    2018-Jun. 2019), worsening after 4 months of summer rest, improving from October 2019 to January 2020 in the second MPE season (Oct. 2019-Jan. 2020), and severely worsening after 7 months of program interruption. We show that an MPE program has clear benefits to the physical and psychoaffective health of older adults, and interruption of these programs could adversely impact participants. These results highlight the need to maintain physical exercise programs or facilitate engagement in physical activity and reduce sedentary behaviour in older adults, particularly in situations such as the COVID-19 pandemic.

    The mitochondrial dysfunction and following oxidative stress, as well as the spread of inflammation plays major roles in the failure to regenerate following severe spinal cord injury (SCI). In this regard, we investigated the neuroprotective effects of hyperbaric oxygen (HBO), as an anti-apoptotic and anti-inflammatory agent, and N-acetylcysteine (NAC), as a mitochondrial enhancer, in SCI.

    Seventy-five female adult Wistar rats divided into five groups (n=15) laminectomy alone (Sham) group, SCI group, HBO group (underwent SCI and received HBO), NAC group (underwent SCI and received NAC), and HBO+NAC group (underwent SCI and simultaneously received NAC and HBO). At the end of study, spinal cord tissue samples were taken for evaluation of biochemical profiles including malondialdehyde (MDA), catalase (CAT), superoxide dismutase (SOD) and glutathione (GSH) levels, immunohistochemistry for caspase-3 as well as gene expressions of interleukin (IL)-10, tumor necrosis factor alpha (TNF-α), and IL-1β. Stereologicactive effects in SCI treatment.Childhood is a time of learning, both individually and through social interactions. But the vulnerability inherent in childhood represents a fitness cost individuals do not have progeny during childhood, and childhood is a net drain of familial or group resources. In this study we model childhood in resource acquisition scenarios where social learning through observation competes with learning through innovation across multiple generations in a variety of environments. In general, observing others allows useful knowledge to be gained more efficiently than self-exploration and may result in significantly greater resource acquisition. However, social learning needing a lengthy childhood to develop advanced cognitive ability may offset the net fitness advantage that might otherwise be gained. Through simulations we demonstrate that individuals with a substantial childhood burden acquire more lifetime resources by observing others than do individuals with negligible childhood costs using self-exploration, as long as the environment is fairly stable. This advantage decreases as the environment becomes less predictable, and reverses in rapidly changing environments where knowledge is unreliable. These results suggest that hominid evolution, with vastly growing cognitive abilities and a longer, more vulnerable childhood, may have been facilitated in similarly stable environments. On the other hand, hominid populations may have been particularly vulnerable to environmental instability. We apply this insight to the Out of Africa Homo sapiens migration roughly 50,000 years ago and show consistency with the serial founder model that best fits current archeological and genetic evidence. Our findings are important for models of social learning, especially those that describe the emergence and spread of Homo sapiens.Myocardial fibrosis is defined as an increased amount of collagen in the myocardium relative to cardiac myocytes. Two main morphologic patterns are recognized 1) replacement fibrosis, which occurs in response to myocyte necrosis (myocardial scarring); and 2) interstitial fibrosis, which is usually a diffuse process and has been shown to be reversible and treatable. Replacement and interstitial fibrosis often coexist and are a constant feature of pathologic cardiac remodeling. In the last twenty years, there has been significant interest in developing objective non-invasive methods to identify and quantitatively assess myocardial fibrosis in vivo, both for diagnostic purposes and to improve stratification of patients. The present Review focuses on the morphologic patterns of myocardial fibrosis observed either at autopsy and heart transplant, or in vivo by non-invasive imaging techniques. Main aim is to provide clues for the differential diagnosis, with emphasis on entities whose diagnosis may be challenging. An update on the diagnostic and prognostic role of imaging, along with recent data on available biomarkers, is also proposed.Somapacitan is a reversible albumin-binding growth hormone (GH) derivative in clinical development for once-weekly administration in patients with adult GH deficiency (AGHD) and children with GH deficiency (GHD). To date, the use of somapacitan in AGHD or severe AGHD has been approved in the USA and Japan, respectively. This study (ClinicalTrials.gov, NCT02962440) investigated the absorption, metabolism and excretion, as well as the pharmacokinetics (PK), of tritium-labelled [3H]-somapacitan. Seven healthy males received a single subcutaneous dose of 6 mg somapacitan containing [3H]-somapacitan 20 MBq. Blood, serum, plasma, urine, faeces, and expired air were collected for radioactivity assessment. Metabolites were identified and quantified in plasma and urine collected. The PK of plasma components were determined, and the radioactive peaks of the most abundant plasma metabolites and urine metabolites were selected for analysis. Twenty-eight days after dosing, 94.0% of the administered dose was recovered as [wed by faeces, and exhalation in expired air was negligible. The low molecular weights of identified urine metabolites demonstrate that somapacitan was extensively degraded to small residual fragments that were excreted (fully biodegradable). The extensive metabolic degradation and full elimination of metabolites in excreta were the major clearance pathways of somapacitan and the key elements in its biological fate. A single dose of 6 mg somapacitan (containing [3H]-somapacitan) in healthy male subjects was well tolerated with no unexpected safety issues identified.

    Achievement of an effective concentration of the pharmaceutically active ingredient in the blood and/or at the target site is an important aspect in the formulation of drugs and therefore needs to be quantified. Any concentration above therapeutic levels can cause toxic effects whereas low concentrations can be sub-therapeutic. This paper investigated different concentrations of selected commercially sourced analytical-grade pure chemicals as potential drug absorption enhancers in vitro and ex vivo to determine the lowest effective concentrations for optimizing drug absorption in oral dosage forms.

    Recombinant cytochrome (CYP) 3A4 enzyme and recombinant p-glycoprotein membrane models were utilized for the investigation of in vitro inhibitory effects of drug absorption enhancers. Promega (2015) protocols were adopted for both assays. The everted porcine intestinal ex vivo model was employed for assessing effects of the drug absorption enhancers on the absorption of propranolol.

    The lowest effective CYP3Aenhancers (e.g., curcumin and quercetin), at specific concentrations, in dosage forms could improve the bioavailability of the BCS Class III and IV drugs that are substrates of CYP3A4 and p-glycoprotein.The co-penetration of micellar vehicles and the encapsulated drugs into the skin layers, as well as the mechanisms underlying the penetration enhancement have not been clearly elucidated. We developed licochalcone A (LA)-loaded glycyrrhiza acid (GA) (GA+LA) micelles for topical delivery of LA into the epidermis. The in vitro co-penetration, penetration pathways, mechanism of interaction between skin and the micelles, and the in vitro and in vivo whitening effect of GA+LA micelles were evaluated. Co-penetration and penetration pathways were visualized on the abdominal skin of rats model with confocal laser scanning microscopy (CLSM) using a nile blue A-labeled GA (GA-NB). We found that GA significantly increased the transport of LA into the skin predominantly via the hair follicles and GA mainly accumulated in the SC and epidermis, while LA was localized in the epidermis and dermis. Moreover, 73.4% of the LA deposited into the epidermis within 12 h and approximately 9.32% of the LA permeated across the SC in the form of entire micelles within 24 h. GA-NB+LA micelles disaggregated and accumulated in the specific skin layers, and the LA released from the carrier penetrated into deeper layers. Moreover, the GA+LA micelles promoted drug penetration via intracellular or intercellular routes by loosening the skin surface and enhancing fluidization through lipid distortion and keratin denaturation. Furthermore, GA+LA micelles exhibited synergistic whitening effect on B16 cells and UVB-exposed C57BL/6 mice. Collectively, GA micelles can enhance penetration of LA to the epidermis mainly via the hair follicles following topical application, and reduce skin pigmentation.In this study, biodegradable and thermosensitive F127 hydrogel containing folic acid.MgOZnO/chitosan hybrid particles (FMZC) was fabricated as a 3D mesenchymal stem cells (MSCs) delivery vehicle for regenerative medicine and wound healing purposes, in such a way to be responsive to lysozyme and UVA irradiation. The results showed that F127 hydrogel containing FMZC is a suitable and nontoxic construct for encapsulation of MSCs in the presence of lysozyme and UVA irradiation, bearing high stem cell viability and proliferation. The final hydrogel, MSC&FMZC, in response to lysozyme induced a higher proliferation rate and migration in human foreskin fibroblast cells (HFF). These phenomena were attributed to the released F.MgOZnO nanocomposites from chitosan microparticles and paracrine factors from MSCs within the hydrogel, resulting in synergistic biological effects. Moreover, lysozyme-treated MSC&FMZC hydrogel showed higher antibacterial and anti-biofilm activity against both Gram-positive and Gram-negative bacteria than bare hydrogel. However, a significant increase in the antibacterial activity of MSC&FMZC was observed as the treated bacteria were subjected to UVA irradiation owing to the photocatalytic activity of F.MgOZnO nanocomposites. Regarding the antibacterial activity and stimulating skin cell behavior of MSC&FMZC hydrogel that can promote the regenerative activities of skin, it could be considered as a promising scaffold for bacteria-accompanied wound healing.Single-cell technologies have rapidly developed in recent years and have already had a significant impact on the research into myeloproliferative neoplasms. The increasing number of publicly available data sets allows characterization of the bone marrow niche in patients and mouse models at unprecedented resolution. Single-cell RNA sequencing has successfully been used to identify and characterize disease-driving cell populations and to identify the alarmin S100A8/A9 as an important mediator of myelofibrosis and potent therapeutic target. It is now possible to execute a streamlined set of experiments to specifically identify and validate actionable target genes functionally with the advance of reliable in vivo models and the possibility of conducting single-cell analyses with a minimal amount of patient material. The advent of large-scale analyses of both hematopoietic and nonhematopoietic bone marrow cells will allow comprehensive network analyses guiding an increasingly detailed mapping of the MPN interactome.The airway epithelium is exposed to a variety of air pollutants, which have been associated with the onset and worsening of respiratory diseases. These air pollutants can vary depending on their composition and associated chemicals, leading to different molecular interactions and biological effects. Mucociliary clearance is an important host defense mechanism against environmental air pollutants and this process is regulated by various ion transporters including the cystic fibrosis transmembrane conductance regulator (CFTR). With evidence suggesting that environmental air pollutants can lead to acquired CFTR dysfunction, it may be possible to leverage therapeutic approaches used in cystic fibrosis (CF) management. The aim of our study was to test whether environmental air pollutants tobacco smoke extract, urban particulate matter, and diesel exhaust particles lead to acquired CFTR dysfunction and whether it could be rescued with pharmacological interventions. Human airway epithelial cells (Calu-3) were exposed to air pollutant extracts for 24 h, with and without pharmacological interventions, with readouts of CFTR expression and function. We demonstrate that both tobacco smoke extract and diesel exhaust particles led to acquired CFTR dysfunction and that rescue of acquired CFTR dysfunction is possible with pharmacological interventions in diesel exhaust particle models. Our study emphasizes that CFTR function is not only important in the context of CF but may also play a role in other respiratory diseases impacted by environmental air pollutants. In addition, the pharmacological interventions approved for CF management may be more broadly leveraged for chronic respiratory disease management.β2-adrenoceptor (β2AR) agonists can stimulate skeletal muscle growth. Their illegal use in food-producing animals, human athletes and bodybuilders causes adverse health effects. In the present study, we developed 3D-QSAR models for predicting the activity of chemicals which can stimulate skeletal muscle growth through β2AR. The activity of 25 β2AR agonists was measured by β2AR-cAMP response element (CRE) -luciferase (Luc) reporter assay. The 3D-QSAR models were built using comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA). The CoMFA and CoMSIA models displayed high external predictability (R2 0.996 and 0.992, respectively) and good statistical robustness, and revealed that electrostatic effects were the most prominent forces influencing the activity of β2AR agonists. The CoMFA and CoMSIA contour plots provided clues regarding the main chemical features responsible for the activity variations and also resulted in predictions which correlate very well with the observed activity. In vitro study with differentiated myotubes showed that the potency orders of β2AR agonists in activating the β2AR-CRE-Luc reporter and in upregulating CREB target genes related to muscle growth were consistent. These 3D-QSAR models provide tools for predicting the activity of chemicals which might be illegally used in livestock or humans to stimulate skeletal muscle growth.Abrus precatorius is a highly toxic seed containing the poison abrin. Similar in properties to ricin, this toxin binds to ribosomes causing cessation of protein synthesis and cell death. With an estimated human lethal dose of 0.1-1 μg/kg, it has been the cause of fatalities due to accidental and intentional ingestion. In present study, we profiled seven human cell lines of different organ origin, for their sensitivity against abrin toxicity. These cell lines are, A549, COLO 205, HEK 293, HeLa, Hep G2, Jurkat, SH-SY5Y and derived from lung, intestine, kidney, cervix, liver, immune and nervous system respectively. MTT, NR, CVDE and LDH assays have been used to determine their response against abrin toxin. Among these cell lines A549 was the most sensitive cell line while Hep G2 was found least sensitive cell lines. Hep G2 cells are shown to have mitochondrial resistance and delayed generation of oxidative stress compared to A549 cells. Remarkable variation in sensitivity against abrin toxicity prompted the evaluation of Bcl2, Bax and downstream caspases in both cells. Difference in Bcl2 level has been shown to play important role in variable sensitivity. Findings of present study are helpful for selection of suitable cellular model for toxicity assessment and antidote screening.The corpus callosum (CC) is a major interhemispheric commissure of placental mammals. Early steps of CC formation rely on guidance strategies, such as axonal branching and collateralization. Here we analyze the time-course dynamics of axonal bifurcation during typical cortical development or in a CC dysgenesis mouse model. We use Swiss mice as a typical CC mouse model and find that axonal bifurcation rates rise in the cerebral cortex from embryonic day (E)17 and are reduced by postnatal day (P)9. Since callosal neurons populate deep and superficial cortical layers, we compare the axon bifurcation ratio between those neurons by electroporating ex vivo brains at E13 and E15, using eGFP reporter to label the newborn neurons on organotypic slices. Our results suggest that deep layer neurons bifurcate 32% more than superficial ones. To investigate axonal bifurcation in CC dysgenesis, we use BALB/c mice as a spontaneous CC dysgenesis model. BALB/c mice present a typical layer distribution of SATB2 callosal cells, despite the occurrence of callosal anomalies. However, using anterograde DiI tracing, we find that BALB/c mice display increased rates of axonal bifurcations during early and late cortical development in the medial frontal cortex. Midline guidepost cells adjacent to the medial frontal cortex are significant reduced in the CC dysgenesis mouse model. Altogether these data suggest that callosal collateral axonal exuberance is maintained in the absence of midline guidepost signaling and might facilitate aberrant connections in the CC dysgenesis mouse model.Mental fatigue impairs both cognitive and physical performance. Bioactive substances (e.g., caffeine) have been used to counteract mental fatigue but could have side effects. The present study aimed to test two non-bioactive strategies to counteract mental fatigue physical activity and listening to music. The participants first performed an arm-pointing task, then carried out a 32-min cognitively demanding task to induce mental fatigue (TLDB task), followed by another arm-pointing task at the end of the experiment. Between the end of the cognitively demanding task and the last arm-pointing task, 20 min went during which participants performed either 15 min of physical activity, of listening to music or of discussion (control). The subjective feeling of mental fatigue was assessed before each arm-pointing task and after the cognitively demanding task. For „physical activity” and „listening to music” groups, EEG was recorded at rest after each evaluation of subjective feeling of mental fatigue and during the cognitively demanding task. An increase in alpha power during the cognitively demanding task evidenced the presence of mental fatigue, without recovery during the following 20-min period. In the control condition, the arm-pointing task performance was deteriorated 20-min after the cognitively demanding task, while it remained stable after both physical activity and listening to music. Furthermore, recovery on the subjective feeling of mental fatigue was similar for both groups. The present results suggested that practicing physical activity and listening to music could be efficient strategies to counteract the negative effects of mental fatigue on motor performances.Understanding of the effects of in utero opioid exposure on neurodevelopment is a priority given the recent dramatic increase in opioid use among pregnant individuals. However, opioid abuse does not occur in isolation-pregnant individuals abusing opioids often have a significant history of adverse experiences in childhood, among other co-occurring factors. Understanding the specific pathways in which these frequently co-occurring factors may interact and cumulatively influence offspring brain development in utero represents a priority for future research in this area. We highlight maternal history of childhood adversity (CA) as one such co-occurring factor that is more prevalent among individuals using opioids during pregnancy and which is increasingly shown to affect offspring neurodevelopment through mechanisms beginning in utero. Despite the high incidence of CA history in pregnant individuals using opioids, we understand very little about the effects of comorbid prenatal opioid exposure and maternal CA history on fetal brain development. Here, we first provide an overview of current knowledge regarding effects of opioid exposure and maternal CA on offspring neurodevelopment that may occur during gestation. We then outline potential mechanistic pathways through which these factors might have interactive and cumulative influences on offspring neurodevelopment as a foundation for future research in this area.The main aim of this study is to present, describe and compare the most significant anatomical classifications of the Internal Iliac Artery (IIA) and its branches, their pros and cons, to relate them to clinical practice and note their clinical importance, and to offer a new classification based on number of main vessels origins. Many classifications covering the detailed morphology of the IIA have been developed, focusing on the destination of vessels making it possible to determine the name and type of branching precisely. However, because the allocation criteria are overdetailed and of doubtful accuracy, these classifications have become impractical for clinical practice and advanced statistical calculations. The argument of this research paper is that highly variable vascularized regions should be classified from either an anatomical point of view to determine detailed morphology aspects or a clinical perspective. Presented classification proposes unification of many branching types presented among various classifications, which look identical when determining the origin pattern from the main vessel and differ only in the destination point of the vessel, what brings clarity and increases the statistical usefulness of the collected data. This should translate into better cooperation between scientists and clinicians and thus benefit patients. The paper proposes a new, clinically useful classification based on the model of vessel origins from the main stem. The IIA is the main vascular supply to the pelvic region, so precise knowledge of origin and its branching pattern is essential for all clinicians, especially for general and orthopaedic surgeons, gynecologists, obstetricians and urologists.

Inconsistencies among evidence-based recommendations by various professional societies can be a source of confusion to practicing clinicians. This article summarizes and compares recommendations from the Canadian Cardiovascular Society management guidelines on adults with CHD (2009), expert consensus from the Pediatric and Congenital Electrophysiology Society and Heart Rhythm Society (2014), European Society of Cardiology (ESC) guidelines on sudden death (2015), position statement from the European Heart Rhythm Association, Association for European Paediatric and Congenital Cardiology, and ESC working group on grown-up CHD (2018), and ESC guidelines on adult CHD (2020). Most recommendations are fundamentally similar, particularly with regards to 1) recommending or considering primary prevention ICDs in adults with CHD and a systemic left ventricular ejection fraction ≤35%, biventricular physiology, and functional class II or III symptoms despite optimal medical therapy; 2) considering ICDs in those with unexplained syncope of suspected arrhythmic etiology and either advanced ventricular dysfunction or inducible sustained ventricular arrhythmias; and 3) considering ICDs in selected patients with tetralogy of Fallot and multiple risk factors for sudden death, such as left ventricular dysfunction, non-sustained ventricular tachycardia, QRS duration ≥180 ms, right ventricular scarring, or inducible sustained ventricular tachycardia. Areas of continued clinical uncertainty, which offer important opportunities for future research, include improving patient selection for primary prevention ICDs in the context of a systemic right ventricle, univentricular heart, or Eisenmenger syndrome.Developing more soluble and stable nanoformulation for the potent anticancer complex of copper diethyldithiocarbamate (CD) is extremely desired. Herein, for the first time, CD nanoparticles (NPs) were formulated by chelating diethyldithiocarbamate to bacterially and green chemically prepared copper oxide NPs (Bio CO NPs and Chemo CO NPs, respectively). Chemo CO NPs were produced in simpler and less time-consuming manner with higher NPs homogeneity. These CO NPs were identified, by X-ray diffractometer, as CuO and Cu2O, respectively. The nanoformulated CD complexes (Bio CD NPs and Chemo CD NPs) which have nanosizes (215.7 nm and 148.1 nm, respectively) with negative zeta potentials (∼-20 mv), exhibited not only high serum stability and solubility but also a potent anticancer effect. More importantly, Chemo CD NPs outperformed Bio CD NPs in the terms of synergistic anticancer index, apoptosis induction (>81% and less then 54%, respectively) and anti-migration efficacy (≥80% and less then 71%, respectively). This could be attributed to smaller nanosize and Cu2O of Chemo CD NPs causing higher cellular uptake with stronger inhibition of aldehyde dehydrogenase 1A1 and more free radical generation in Chemo CD NPs-treated cancer cells than Bio CD NPs. This distinct anticancer efficacy of novel Chemo CD NPs deserves further investigation using animal models.Orexin receptors expressed in basolateral amygdala (BLA) have been proposed for memory processing and hippocampal plasticity. There are several investigations about the effect of the adrenergic system in BLA on memory enhancement. However, there is no information about the molecular basis of this effect. Adrenergic and orexinergic fibers are found in BLA. In this study, the effects of both adrenergic and orexinergic systems were investigated on the amygdala function. To this end, the selective beta 2 adrenergic agonist (clenbuterol) and orexin receptors’ antagonists (OX1R and OX2R, SB-334867-A and TCS-OX2-29, respectively) were administered into the BLA, then the high frequency stimulation (200-Hz) was applied to the perforant pathway and the synaptic plasticity of the dentate granular cells was studied in anaesthetized rats. Clenbuterol injection into the BLA enhanced the population spike (PS) component of LTP in the dentate gyrus (DG), as compared to that observed after dimethyl sulfoxide treatment. In addition, after orexin 1 or 2 receptor antagonists (SB-334867-A and TCS-OX2-29, respectively) injecting into the BLA, the enhancing effect of clenbuterol on PS was reduced. Moreover, the population excitatory post-synaptic potential also decreased in the SB-clenbuterol and TCS- clenbuterol experimental groups. However, the PS amplitude was also decreased in the group treated only by SB or TCS relative to the clenbuterol treated group. The PS amplitude or EPSP slope in the groups treated by both application of orexin receptors’ antagonists and clenbuterol was considerably lower relative to the groups treated only by orexin receptors’ antagonists. It is concluded that the BLA orexinergic system modulates hippocampal plasticity in relation with the adrenergic system.Toxoplasma gondii (T. gondii) is an intracellular protozoan that infects the fetus through the placenta and leads to severe complications in the fetus. One of the complications of congenital toxoplasmosis is spontaneous abortion. The prevalence of toxoplasmosis infection was investigated among spontaneously aborted fetuses (SAFs), and the genotypes of parasite isolates were determined in the present study. Placentas from 330 samples of SAFs were collected in Jahrom (Fars province) from February to September 2018. DNA was extracted from each placental tissue. The T. gondii infection was detected using nested polymerase chain reaction (Nested-PCR) assay based on a 529 bp repeat element (RE) gene. Afterward, Toxoplasma was genotyped using PCR-restriction fragment length polymorphism (PCR-RFLP) based on the GRA6 gene. The frequency of T. gondii infection was found to be 14.5% (48 out of 330 samples). Genotyping of nine T. gondii isolates revealed that all belonged to genotype II. Statistically, the prevalence of T. gondii infection was significantly correlated with the education levels of the mothers and the age of the fetus (P less then 0.05). The lowest prevalence of Toxoplasma infection belonged to mothers with university education and the highest frequency of infection was observed among the fetuses in the age group of 8-9 weeks. The findings of the present study suggest a significant role for toxoplasmosis in SAFs in Jahrom city.Vibrio alginolyticus is an important zoonotic marine pathogenic bacterium. Previous studies on the mechanism of innate immune against V. alginolyticus infection have been limited to aquatic animals, however, how V. alginolyticus activates mammalian immune cells has not been fully clarified. Here, ELISA combined RT-qPCR assays were used to detect the secretion and transcription level of pro-inflammatory cytokines and TLRs during V. alginolyticus infection of mice peritoneal macrophages (PMϕs). Western blotting was used to explore the phosphorylation levels of p38, JNK, ERK, AKT and NF-κB protein. Immunofluorescence assay was used to determine the location of NF-κB protein. Inhibition assay was used to study the role of up-regulated TLR in activated signaling pathways and the role of these pathways in the release of pro-inflammatory cytokines. Our data showed that V. alginolyticus can up-regulate the expression levels of IL-1β, IL-6, IL-12 and TNF-α in PMϕs. In addition, V. alginolyticus stimulation activated the phosphorylation of p38, JNK and ERK were TLR2 heterodimers-dependent, whereas inhibitors of SB203580 (p38), SCH772984 (ERK) and SP600125 (JNK) significantly reduced IL-1β, IL-6, IL-12 and TNF-α production. We further revealed that V. alginolyticus activated the signaling pathways of AKT via TLR2 heterodimers. The inhibitor of MK-2206 2HCl (AKT) negatively regulated the IL-1β, IL-6 and TNF-α release levels. Moreover, V. alginolyticus infection of PMϕs resulted in TLR2 heterodimers-mediated activation of NF-κB and induced translocation of phosphorylated NF-κB protein from the cytoplasm into the nucleus via IκBα degradation. V. alginolyticus induced IL-1β, IL-6, IL-12 and TNF-α release were blocked by the specific NF-κB inhibitor, BAY 11-7082. Taken together, our results suggested that activation of the TLR2 heterodimers-mediated downstream signaling pathways NF-κB, MAPK and AKT is responsible for inflammatory response during Vibrio alginolyticus infection in vitro.Ungulates visually and olfactorily discriminating between vegetation patches in grasslands often encounter restriction of target visibility due to light intensity changes; however, little is known about their performance in such a context. We developed and tested an apparatus for evaluating the visual and olfactory discrimination ability of cattle under controlled target visibility, focusing on the discrimination at a short distance. The apparatus was designed to contain a discrimination target under a sliding cover of variable light transmission levels and behind a vent of a fixed size and aperture so as to control the visibility of the target (14-100% restrictions) while ensuring a constant level of odor. Twelve Japanese Black cows were allowed to choose between two apparatuses presenting a pair of targets green forage versus empty, green forage versus dead forage, or green forage versus green-dead mixture. Cows rapidly learned to slide open the cover to reach the selected target, consistently chose the green forage against the alternative except against the green-dead mixture under 100% visual restriction, and remembered the reaching procedure for at least 16 days. The results indicate the usefulness of the apparatus for assessing close visual and olfactory discrimination ability of cattle in detail.The context specificity of habituation has been demonstrated in earthworms. After the habituation of the retraction response to a light, a recovery of the response was observed when subjects are re-habituated in a different context. Some theories assume that an association between the context and the unconditioned stimulus could underlie this result. A series of experiments were conducted in order to test this issue. We assessed the potential disruptive effects of post-exposure (extinction effect) and pre-exposure of the context (latent inhibition effect) on the establishment of a context-US association. A recovery of response during subsequent rehabituation test was expected. The results of Experiment 1 showed that the extinction was effective, the post-exposure of the context after habituation produced a recovery of the retraction response. This result was replicated in Experiment 2 where the post-exposure condition was compared with a pre-exposure one. However, the pre-exposure to the context did not result in a recovery of the response in the rehabituation test, but also produced a general decrement on the response during the habituation training, that it has been interpreted as decrement in context’s salience. In summary, these results suggest the involvement of associative and nonassociative processes in habituation learning.Motivated behavior has long been studied by psychologists, ethologists, and neuroscientists. To date, many scientists agree with the view that cue and reward attraction is the product of a dopamine-dependent unconscious process called incentive salience or „wanting”. This process allows the influence of multiple factors such as hunger and odors on motivational attraction. In some cases, however, the resulting motivated behavior differs from what the incentive salience hypothesis would predict. I argue that seeking behavior under reward uncertainty illustrates this situation Organisms do not just „want” (appetite-based attraction) cues that are inconsistent or associated with reward occasionally, they „hope” that those cues will consistently predict reward procurement in the ongoing trial. Said otherwise, they become motivated to invest time and energy to find consistent cue-reward associations despite no guarantee of success (effort-based attraction). A multi-test comparison of performance between individuals trained under uncertainty and certainty reveals behavioral paradoxes suggesting that the concept of incentive salience cannot fully account for responding to inconsistent cues. A mathematical model explains how appetite-based and effort-based attractions might combine their effects.Long-chain acyl-CoA synthetase 1 (ACSL1) is a member of the acyl-CoA synthetase family that plays a vital role in lipid metabolism. We have previously shown that the ACSL1 gene regulates the composition of unsaturated fatty acids (UFAs) in bovine skeletal muscle, which in turn regulates the fatty acid synthesis and the generation of lipid droplets. Here, we used RNA-Seq to screen circRNAs that regulated the expression of ACSL1 gene and other UFA synthesis-related genes by RNA interference and noninterference in bovine adipocytes. The results of KEGG pathway analysis showed that the parental genes of differentially expressed (DE)-circRNAs were primarily enriched in the adipocytokine signaling pathway. The prediction results showed that novel_circ_0004855, novel_circ_0001507, novel_circ_0001731, novel_circ_0005276, novel_circ_0002060, novel_circ_0005405 and novel_circ_0004254 regulated UFA synthesis-related genes by interacting with the related miRNAs. These results could help expand our knowledge of the molecular mechanisms of circRNAs in the regulation of UFA synthesis in bovine adipocytes.

    Thoracic outlet syndrome (TOS) is most often referred to vascular surgeons. However, there is a lack of understanding of the malpractice cases involving TOS. The goal of this study is to better understand the medicolegal landscape related to the care of TOS.

    The Westlaw Edge AI-powered proprietary system was retrospectively reviewed for malpractice cases involving TOS. A Boolean search strategy was used to identify target cases under the case category of „Jury Verdicts & Settlements” for all state and federal jurisdictions from 1970 to September 2020. The settled case was described but not included in the statistical analysis. Descriptive statistics were used to report our findings, and when appropriate. The P ≤ .05 decision rule was established a priori as the null hypothesis rejection criterion to determine associations between jury verdicts outcomes and state’s tort reform status.

    In this study, 39 cases were identified and met the study’s inclusion criteria from the entire Westlaw Edge database.ted complication. Excluding one case with a settlement of $965,000, 30 of 38 (78.9%) cases went to trials and received defense verdicts. Eight cases (20.5%) were found in favor of plaintiffs with a median payout of $725,581.

    This study highlighted higher than average payouts to plaintiffs and risk factors that may result in malpractice lawsuits for surgeons undertaking TOS treatment. Future studies are needed to further clarify the relationships between tort reform and outcomes of malpractice cases involving TOS.

    The implementation of integrated vascular surgery training programs was recently shown to be associated with an increase in women entering the field. However, whether this has precipitated a subsequent increase in the active participation of women in academic vascular societies remains unclear. We sought to examine the trends of academic inclusion of women vascular surgeons and surgical trainees over the past 15years at the Southern Association for Vascular Surgery (SAVS).

    Scientific programs for annual meetings of the SAVS, and program matriculation statistics from the Accreditation Council for Graduate Medical Education, were reviewed for the period of 2006 to 2020. Yearly rates and 3-year averages of conference and society participation and vascular surgery training program matriculation rates were calculated and compared with proportion testing. Spearman correlation testing was used to compare trends, with ρ ≥0.600 defined as a strong correlation.

    Percutaneous devices for creation of native arteriovenous fistulae offer an alternative to traditional open surgical techniques. The 4 Fr WavelinQ EndoAVF System was developed as a lower profile alternative to facilitate access through smaller vessels and minimize access site complications; The current report is the original first experience of this device, assessing outcome in 120 patients followed for 6 months.

    The use of the 4 Fr WavelinQ system in three studies, EASE (32 patients), EASE-2 (24 patients), and the EU post-market clinical follow-up study (64 patients) was aggregated and analyzed. Patients were followed with duplex ultrasound at discharge and follow-up visits at 1, 3, and 6 months. Primary, assisted primary, and secondary patency rates were evaluated as Kaplan-Meier (KM) estimates and standard errors. Time to maturity and time to successful cannulation were defined as the mean ± SD days from the procedure in patients enrolled on dialysis.

    Procedural success was achieved in 116 patients (st that the 4 Fr device is a useful percutaneous alternative to open surgical AVF or endovascular AVF with larger-bore devices.

    Percutaneous creation of native dialysis fistulae with the 4 Fr WavelinQ EndoAVF System is safe and effective, with favorable durability and a low rate of serious complications and reinterventions through 6-month follow-up. Utilization of the 4F device allows for percutaneous fistula creation between the radial artery and radial vein or the ulnar artery and ulnar vein. These findings suggest that the 4 Fr device is a useful percutaneous alternative to open surgical AVF or endovascular AVF with larger-bore devices.

    The prevalence and incidence of peripheral arterial disease (PAD) are increasing in the general population. There are limited data on the epidemiology of Chronic Limb-Threatening Ischemia (CLTI), which likely represents <10% of all PAD patients; in the general population its overall prevalence is 0,74%. This specific subgroup of patients has severe presentations of the disease, in whom the symptoms often correlate with a specific infrainguinal morphological pattern known as chronic total occlusion (CTO), often difficult to cross in a standard endovascular fashion. In the last years, several techniques have been developed to overcome limitations of standard antegrade endoluminal or subintimal approaches, if they fails. Advanced Techniques Subintimal techniques Crush balloon, Parallel wire, S.A.F.A.R.I. and Double-balloon techniques are described in detail. Furthermore, a homemade re-entry device is described, in order to provide access to the distal true lumen in extreme, uncrossable cases. Retrograde apps of the procedures. But their use in clinical practice still needs to be standardized.

    Effective handling of the advanced techniques described in this manuscript is of paramount importance because only 20% of patients have a CTO that is crossable with standard techniques. So, they can help the endovascular surgeon to increase the success rates in complex anatomic patterns too. Furthermore, the possibility of treating these CTOs with only guidewires and catheters allows to reduce the costs of the procedures. But their use in clinical practice still needs to be standardized.

    Arteriovenous grafts (AVGs) are frequently needed in hemodialysis (HD) patients with unsuitable superficial veins. First cannulation of standard arteriovenous grafts (sAVGs) still require about 2weeks after implantation. Early cannulation arteriovenous grafts (eAVGs) were suggested to overcome this shortcoming. The present randomized study proposed to compare the clinical outcomes of sAVGs and eAVGs in HD patients.

    The present single-center randomized clinical study recruited 477 HD patients indicated for AVG creation. They included 236 in the sAVG group and 241 in the eAVG group. Eligible patients were simply randomized and allocated to the studied groups using 11 allocation ratio. Blinding was secured using the sealed envelope technique. Enrolled patients were followed up for 12months. The primary outcome in the present study was primary, primary assisted, and secondary patency rates at 12months. Other outcome parameters included time to first cannulation, graft complications, and mortality.

    Comparisoroup at 12 months with the added advantage of earlier time to first cannulation.

    The indication of percutaneous renal transluminal angioplasty (PTRA) in fibromuscular dysplasia (FMD) is mainly based on renal artery stenosis (RAS) due to atherosclerosis criteria, which are not specific to FMD. Consequently, the selection of patients who could benefit from this treatment and its effectiveness remain uncertain. The aims of this study were to (1) report the effects of PTRA guided by trans-stenotic pressure measurements on hypertension 7months after treatment; (2) assess the impact of pressure measurement to guide treatment efficacy in comparison to visual angiographic parameters; and (3) evaluate the reproducibility and accuracy of the stenosis measurement using a 4F catheter in comparison to a pressure guidewire.

    This prospective multi-centric study analyzed 24 patients with hypertension with RAS due to FMD that required PTRA. Clinical, duplex ultrasound, and angiographic indices were collected, and patients were followed up for 7months (±1month). Angiographic indices were measured twicesystolic gradient ≤10mmHg or reduced by at least 80% after angioplasty, promotes a high success rate for PTRA in hypertension due to FMD RAS.

    In patients selected by clinical indicators and duplex ultrasound, reaching a translesional systolic gradient ≤10 mmHg or reduced by at least 80% after angioplasty, promotes a high success rate for PTRA in hypertension due to FMD RAS.Ribosome-inactivating proteins (RIPs) are capable of removing a specific adenine from 28S ribosomal RNA, thus inhibiting protein biosynthesis in an irreversible manner. In this study, recombinant OsRIP1, a type 1 RIP from rice (Oryza sativa L.), was investigated for its anti-proliferative properties. Human cervical cancer HeLa cells were incubated in the presence of OsRIP1 for 24-72 h. OsRIP1 treatment yielded an anti-proliferation response of the HeLa cells and resulted in apoptotic-like blebbing of the plasma membrane without causing DNA fragmentation. OsRIP1 labeled with FITC accumulated at the cell surface. Pull-down assays identified ASPP1 (Apoptosis-Stimulating Protein of p53 1) and IFITM3 (interferon-induced transmembrane protein 3) as potential interaction partners for OsRIP1. Transcript levels for several critical genes related to different signaling pathways were quantified by RT-qPCR. OsRIP1 provoked HeLa cells to undergo caspase-independent cell death, associated with a significant transcriptional upregulation of the apoptotic gene PUMA, interferon regulatory factor 1 (IRF1) and the autophagy-related marker LC3. No changes in caspase activities were observed. Together, these data suggest that apoptotic-like events were involved in OsRIP1-driven caspase-independent cell death that might trigger the IRF1 signaling pathway and LC3-mediated autophagy.This study was to evaluate the antifatigue effect of T. heterochaetus and explore the underlying mechanism of action. T. heterochaetus extract was treated to mice for 28 days. On the 28th day, after weight loaded swimming test. The levels of antioxidant enzymes and levels of pro- and anti-inflammatory cytokines in the liver and muscles of exercised mice were evaluated. mRNA and protein expression levels of Nrf2, SOD, HO-1, and Keap-1 were evaluated using RT-PCR and western blot analysis. The low (2.70 mg/0.5 ml/20 g) and medium (5.41 mg/0.5 ml/20 g) dose enhanced the activities of antioxidant enzymes like SOD, CAT and GPx in the liver and skeletal muscle thereby enhancing the antifatigue effect. The low and medium doses showed good anti-inflammatory effects by evaluating the levels of pro and anti-inflammatory cytokines such as TNF-α, IL-1β, IL-6, and IL-10 both in the liver and skeletal muscle. Furthermore, RT-PCR and western blot analysis showed increased expression of HO-1, SOD, Nrf2, and decreased expression of Keap-1 gene and proteins in liver and skeletal muscle of T. heterochaetus treated group mice. The current results indicate that T. heterochaetus exert the antifatigue effect through attenuating oxidative stress injury and inflammatory responses through the Nrf2/ARE-mediated signaling pathway.To develop a suitable automobile design as per each driver’s characteristics and state, it is important to understand the brain function in acquiring driving skills. Reportedly, the brain structures of professionals, such as athletes and musicians, and those who have received training in special skills, undergo changes with training. However, the development process of the brain in terms of acquiring driving skills has not yet been clarified. In this study, we evaluated the effects of driving training on the brain and observed an increase in the volume of the right cerebellum after short-term training (3 days). The right cerebellum is responsible for controlling the right hand and right foot, which are important for driving. Drivers train to control a vehicle smoothly at high speeds at gymkhana and pylon slalom courses, which are often used in motor sports. The brain structure was analyzed before and after training using magnetic resonance imaging. Voxel-based morphometry was used to assess possible structural changes. First, the lap times after training were clearly shortened and vehicle dynamics were more stable, indicating that the drivers’ skill level clearly improved. Second, brain structural analysis revealed a volumetric increase in the right cerebellum. The cerebellum is involved in the process of learning sensory motor skills, such as smooth steering and pedal operations, driving course shape, and vehicle size perception. These results suggest a new inner model for driving operation and support the hypothesis that motor learning affects the cerebellum during vehicle driving training.The shorter life spans of mice provide an exceptional experimental gerontology scenario. We previously described increased bizarre (disruptive) behaviors in the 6-month-old 3xTg-AD mice model for Alzheimer’s disease (AD), compared to C57BL/6J wildtype (NTg), when confronting new environments. In the present work, we evaluated spontaneous gait and exploratory activity at old age, using 16-month-old mice. Male sex was chosen since sex-dependent psychomotor effects of aging are stronger in NTg males than females and, at this age, male 3xTg-AD mice are close to an end-of-life status due to increased mortality rates. Mice’s behavior was evaluated in a transparent test box during the neophobia response. Stretching, jumping, backward movements and bizarre circling were identified during the gait and exploratory activity. The results corroborate that in the face of novelty and recognition of places, old 3xTg-AD mice exhibit increased bizarre behaviors than mice with normal aging. Furthermore, bizarre circling and backward movements delayed the elicitation of locomotion and exploration, in an already frail scenario, as shown by highly prevalent kyphosis in both groups. Thus, the translational study of co-occurrence of psychomotor impairments and anxiety-like behaviors can be helpful for understanding and managing the progressive functional deterioration shown in aging, especially in AD.One hallmark feature of Parkinson’s disease (PD) is Lewy body pathology associated with misfolded alpha-synuclein. Previous studies have shown that striatal injection of alpha-synuclein preformed fibrils (PFF) can induce misfolding and aggregation of native alpha-synuclein in a prion-like manner, leading to cell death and motor dysfunction in mouse models. Here, we tested whether alpha-synuclein PFFs injected into the medial prefrontal cortex results in deficits in interval timing, a cognitive task which is disrupted in human PD patients and in rodent models of PD. We injected PFF or monomers of human alpha-synuclein into the medial prefrontal cortex of mice pre-injected with adeno-associated virus (AAV) coding for overexpression of human alpha-synuclein or control protein. Despite notable medial prefrontal cortical synucleinopathy, we did not observe consistent deficits in fixed-interval timing. These results suggest that cortical alpha-synuclein does not reliably disrupt fixed-interval timing.
