Bilirubin is produced by the breakdown of hemoglobin and is normally catabolized and excreted. Neurotoxic accumulation of serum bilirubin often occurs in premature infants. The homozygous Gunn rat lacks uridine diphosphate glucuronosyltransferase 1A1 (UGT1A1), the enzyme needed to biotransform bilirubin. This rodent model of hyperbilirubinemia emulates many aspects of bilirubin toxicity observed in the human infant. We demonstrate that choline supplementation in early postnatal development is neuroprotective in the choline-restricted Gunn rat, when hyperbilirubinemia is induced on postnatal day 5.

We first compared behaviors and cerebellar weight of pups born to dams consuming regular rat chow to those of dams consuming choline-restricted diets. Second, we measured behaviors and cerebellar weights of pups born to choline-restricted dams, reared on a choline-restricted diet, supplemented with or without choline, and treated with or without sulfadimethoxine (SDMX).

A choline-restricted diet did not change the potential use of choline as an intervention capable of ameliorating the effect of bilirubin on the choline-restricted developing brain. This article opens the door for future studies on the action of choline in the presence of hyperbilirubinemia, especially in preterm neonates.Integrins are heterodimeric transmembrane cell adhesion molecules made up of alpha (α) and beta (β) subunits arranged in numerous dimeric pairings. These complexes have varying affinities to extracellular ligands. Integrins regulate cellular growth, proliferation, migration, signaling, and cytokine activation and release and thereby play important roles in cell proliferation and migration, apoptosis, tissue repair, as well as in all processes critical to inflammation, infection, and angiogenesis. This review presents current evidence from human and animal studies on integrin structure and molecular signaling, with particular emphasis on signal transduction in infants. We have included evidence from our own laboratory studies and from an extensive literature search in databases PubMed, EMBASE, Scopus, and the electronic archives of abstracts presented at the annual meetings of the Pediatric Academic Societies. To avoid bias in identification of existing studies, key words were short-listed prior to the actual search both from anecdotal experience and from PubMed’s Medical Subject Heading (MeSH) thesaurus. IMPACT Integrins are a family of ubiquitous αβ heterodimeric receptors that interact with numerous ligands in physiology and disease. Integrins play a key role in cell proliferation, tissue repair, inflammation, infection, and angiogenesis. This review summarizes current evidence from human and animal studies on integrin structure and molecular signaling and promising role in diseases of inflammation, infection, and angiogenesis in infants. This review shows that integrin receptors and ligands are novel therapeutic targets of clinical interest and hold promise as novel therapeutic targets in the management of several neonatal diseases.Two decades of studies suggest that computerized cognitive training (CCT) has an effect on cognitive improvement and the restoration of brain activity. Nevertheless, individual response to CCT remains heterogenous, and the predictive potential of neuroimaging in gauging response to CCT remains unknown. We employed multivariate pattern analysis (MVPA) on whole-brain resting-state functional connectivity (rsFC) to (neuro)monitor clinical outcome defined as psychosis-likeness change after 10-hours of CCT in recent onset psychosis (ROP) patients. Additionally, we investigated if sensory processing (SP) change during CCT is associated with individual psychosis-likeness change and cognitive gains after CCT. 26 ROP patients were divided into maintainers and improvers based on their SP change during CCT. A support vector machine (SVM) classifier separating 56 healthy controls (HC) from 35 ROP patients using rsFC (balanced accuracy of 65.5%, P  less then  0.01) was built in an independent sample to create a naturalistic model representing the HC-ROP hyperplane. This model was out-of-sample cross-validated in the ROP patients from the CCT trial to assess associations between rsFC pattern change, cognitive gains and SP during CCT. Patients with intact SP threshold at baseline showed improved attention despite psychosis status on the SVM hyperplane at follow-up (p  less then  0.05). Contrarily, the attentional gains occurred in the ROP patients who showed impaired SP at baseline only if rsfMRI diagnosis status shifted to the healthy-like side of the SVM continuum. Our results reveal the utility of MVPA for elucidating treatment response neuromarkers based on rsFC-SP change and pave the road to more personalized interventions.

Moyamoya is a chronic cerebrovascular condition of unclear etiology characterized by progressive occlusion of 1 or both internal carotid arteries with neovascular collateral formation. With both an idiopathic form (moya-moya disease) and congenital condition-associated form (moyamoya syndrome), it can cause ischemic and hemorrhagic stroke. Recent findings in Kentucky have challenged traditional estimates of its incidence in US populations. Using the Kentucky Appalachian Stroke Registry (KApSR), our aim was to further characterize its incidence as a cause of stroke and to understand the patient population in Appalachia.

A retrospective review of moyamoya patients was performed using the KApSR database. Data collected included demographics, county location, risk factors, comorbidities, and health-care encounters from January 1, 2012, to December 31, 2016.

Sixty-seven patients were identified; 36 (53.7%) resided in Appalachian counties. The cohort accounted for 125 of 6,305 stroke admissions, representing l number of stroke admissions in Kentucky; these patients were more likely to develop an ischemic stroke rather than a hemorrhagic stroke. Autoimmune disorders were more prevalent in moyamoya patients than in the general population. The reduced frequency of traditional stroke risk factors within the Appalachian group suggests an etiology distinct to the population.

Previous studies have established the risk of bone loss among people living with HIV affected by antiretroviral therapy drug side effects and inadequate nutrient intake. Until recently, there have been limits on using the medical nutrition therapy (MNT) to improve dietary habits for promoting bone health among people living with HIV. This was a randomized controlled trial study aimed to investigate the effectiveness of MNT in improving the bone health in people living with HIV by promoting dietary habits.

PLHIV at Queen Savang Vadhana Memorial Hospital were randomly grouped (by quota sampling) into the MNT group (intervention group) and the control group. One hundred and thirty PLHIV were recruited to participate in this study by convenient sampling. Sixty-five participants of the MNT group made a total of 6 appointments (for 12 weeks) to meet registered dietitians for receiving MNT to improve dietary habits for improving bone health, while 65 participants in the control group received only routine care at the hospital service center.

In general, participants in the MNT group had significant increase in the amounts of calcium, vitamin D, potassium, and phosphorus intakes and length of exercise after the final week compared with before intervention. Also, they had significantly higher amount of nutrient intakes (calcium, vitamin D, potassium, and phosphorus) and length of exercise than the control group after finishing the final week of the experiment.

In conclusion, MNT is effective for improving food habits and physical activity to promote bone health among people living with HIV.

In continuous renal replacement therapy (CRRT)-treated patients, a net ultrafiltration (NUF) rate >1.75 mL/kg/h has been associated with increased mortality. However, there may be heterogeneity of effect of NUF rate on mortality, according to patient characteristics.

To investigate the presence and impact of heterogeneity of effect, we performed a secondary analysis of the „Randomized Evaluation of Normal versus Augmented Level of Renal Replacement Therapy” (RENAL) trial. Exposure was NUF rate (weight-adjusted fluid volume removed per hour) stratified into tertiles (<1.01 mL/kg/h; 1.01-1.75 mL/kg/h; or >1.75 mL/kg/h). Primary outcome was 90-day mortality. Patients were clustered according to baseline characteristics. Heterogeneity of effect was assessed according to clusters and baseline edema and related to the additional impact of baseline cardiovascular Sequential Organ Failure Assessment (SOFA) score. We excluded patients with missing values for baseline weight and/or treatment duration.

We identified 2 clusters. The largest (cluster 1; n = 941) included more severely ill patients, with more sepsis, more edema, and more vasopressor therapy (all p < 0.001). Compared to the middle tertile, the probability of harm was greater with the high tertile of NUF rate in patients in cluster 1 and in patients with baseline edema (probability of harm, cluster 1 99.9%; edema 99.1%). Moreover, higher baseline cardiovascular SOFA score also increased mortality risk with both high and low compared to middle NUF rates in cluster 1 patients and in patients with edema.

In CRRT patients, both high and low NUF rates may be harmful, especially in those with edema, sepsis, and greater illness severity. Cardiovascular SOFA scores modulate this association. Additional studies are needed to test these hypotheses, and targeted trials of NUF rates based on risk stratification appear justified.

ClinicalTrials.gov identifier NCT00221013.

ClinicalTrials.gov identifier NCT00221013.This study aimed to evaluate the effect of different toothbrushing routines and different kinds of toothpaste on the interproximal fluoride concentration after toothbrushing and its clinical relevance to the recommendations given to patients regarding the process of toothbrushing. Eight adults participated a total of 8 times in order to test different toothbrushing routines with different amounts of toothpaste (1 or 2 cm), durations (1 or 2 min) and amounts of water after toothbrushing (10 or 20 mL). An additional 8 adults participated 6 times in total to test different forms of toothpaste administration (paste, gel and foam) with different amounts of water after toothbrushing (no rinsing or 10 mL). Interdental saliva samples were collected from proximal sites 25/26 and 46/45 using small paper points, before and up to 60 min after toothbrushing. The fluoride concentration was measured by an ion-specific electrode. The area under the curve, saliva fluoride concentration versus time, was calculated. Differences between the groups were tested by ANOVA with Tukey’s multiple comparisons test. An increase in fluoride concentration of 47.2% was observed when the amount of toothpaste increased from 1 to 2 cm (p less then 0.01), 26.8% when increasing the duration from 1 to 2 min (p less then 0.01) and 41.2% when reducing the amount of water rinsing from 20 to 10 mL (p less then 0.01). The paste and gel resulted in higher fluoride concentration (p less then 0.01) compared with foam. These findings suggest that the amount of toothpaste, the duration and the amount of water have a significant effect on fluoride concentration after toothbrushing. Furthermore, despite the lower amount of fluoride, the gel gives almost the same fluoride concentration after toothbrushing as the toothpaste. The results confirm the importance of giving clear advice to patients regarding the process of toothbrushing.

The molecular pathogenesis of Alzheimer’s disease (AD) is still not clear, and the relationship between gene expression profile for different brain regions has not been studied.

Bioinformatic analysis at the genetic level has become the best way for the pathogenesis research of AD, which can analyze the abovementioned relationship.

In this study, the datasets of AD were obtained from the Gene Expression Omnibus (GEO), and Qlucore Omics Explorer (QOE) software was used to screen differentially expressed genes of GSE36980 and GSE9770 and verify gene expression of GSE63060. The Gene Ontology (GO) function enrichment analysis of these selected genes was conducted by Database for Annotation, Visualization, and Integrated Discovery (DAVID), and then the gene/protein interaction network was established by STRING to find the related proteins. R language was used for drafting maps and plots.

There were 20 differentially expressed genes related to AD selected from GSE36980 (p = 6.2e-6, q = 2.9422e-4) and GSE9770 (p = 3.3e-4, q = 0.016606). Their expression levels of the AD group were lower than those in the control group and varied among different brain regions. Cellular morphogenesis and establishment or maintenance of cell polarity were enriched, and LRRTM1 and RASAL1 were identified by the integration network. Moreover, the analysis of GSE63060 verified the expression level of LRRTM1 and RASAL1 in Alzheimer’s patients, which was much lower than that in normal people aged >65 years.

The pathogenesis of AD at molecular levels may link to cell membrane structures and signal transduction; hence, a list of 20 genes, including LRRTM1 and RASAL1,potentially are important for the discovery of treatment target or molecular marker of AD.

The liver metastases of colorectal cancer (CRC) can be surgically treated in selected cases, with continuously improving results. Matrix metalloproteinases (MMPs) contribute to cancer invasion by degrading the extracellular matrix, and elevated levels of MMP-2, MMP-8, and MMP-9 have been detected in several malignancies. Myeloperoxidase (MPO) is a mediator of tissue damage that can oxidatively activate latent MMPs. We evaluated the prognostic value of MMP-2, MMP-8, and MMP-9 in tissue samples of primary tumors and liver metastases and the pre- and postoperative serum levels of MMP-8, MMP-9, and MPO in CRC patients undergoing liver resection.

Tissue and serum samples were obtained from 111 patients who had primary colorectal tumors and their liver metastases surgically treated at the Helsinki University Hospital between 1988 and 2007. Tissue expression of MMP-2, MMP-8, and MMP-9 in primary tumors and liver metastases was evaluated by immunohistochemistry. Pre- and postoperative serum concentrations of MMP-acteristics.

Low preoperative MPO in serum might identify patients at high risk of recurrence and death after resection of colorectal liver metastases. Elevated preoperative MPO and high expression of MMP-9 in colorectal tumor tissue indicate an improved prognosis. The use of these biomarkers should be adjusted according to clinical characteristics.

Somatostatin inhibits intestinal motility and hormonal secretion and is a potent arterial vasoconstrictor of the splanchnic blood flow. It is unknown if somatostatin concentrations are associated with central hemodynamic measurements in patients with advanced heart failure (HF).

A prospective study of HF patients with a left ventricular ejection fraction (LVEF) <45% referred to right heart catheterization (RHC) for evaluation for heart transplantation (HTX) or left ventricular assist device (LVAD).

Fifty-three patients were included with mean LVEF 18 ± 8% and majority in NYHA-class III-IV (79%). Median plasma somatostatin concentration was 18 pmol/L. In univariable regression analysis, log(somatostatin) was associated with increased central venous pressure (CVP; r2 = 0.14, p = 0.003) and a reduced cardiac index (CI; r2 = 0.15, p = 0.004). When adjusted for selected clinical variables (age, gender, LVEF, eGFR and BMI), log(somatostatin) remained a significant predictor of CVP (p = 0.044). Increased somatostatin concentrations predicted mortality in multivariable models (hazard ratio 5.2 [1.2-22.2], p = 0.026) but not the combined endpoint of death, LVAD implantation or HTX.

Somatostatin concentrations were associated with CVP and CI in patients with HF. The pathophysiological mechanism may be related to congestion and/or hypoperfusion of the intestine. Somatostatin was an independent predictor of mortality in advanced HF.

To evaluate the efficacy and safety of topical β-blockers in the treatment of superficial infantile hemangiomas (SIH) and mixed infantile hemangiomas (MIH), respectively, and compare the efficacy and safety of topical β-blockers with other interventions.

The PRISMA guidelines were adhered to. We searched for randomized controlled trials in databases from 2010 to 2018 comparing topical β-blockers with other interventions for infantile hemangiomas. The outcomes evaluated were efficacy and adverse effects. Data analyses were performed using RevMan 5.3. Publication bias was assessed to account for bias in patient selection.

Eleven studies, involving 1,235 patients, were subjected to this meta-analysis. Six studies compared topical β-blockers with other interventions (propranolol, placebo, corticosteroids or pulsed dye laser) in treating SIH, and 5 studies evaluated the efficacy and safety of a topical β-blocker when it was combined with another intervention in treating MIH. A topical β-blocker was discovereIH and that they are of additive value in treating MIH.

This meta-analysis provided evidence that topical β-blockers may replace oral propranolol as first-line therapy for SIH and that they are of additive value in treating MIH.

Furosemide is commonly used off-label in the neonatal intensive care unit (NICU), but current dosing practices vary widely.

To describe dosing practices including route, dose, and duration of exposure to furosemide in a large number of community and tertiary NICUs across North America.

Using the Pediatrix Medical Group Clinical Data Warehouse, we identified infants who received ≥1 dose of furosemide between 1997 and 2016. We excluded infants with incomplete dosing data. We calculated average daily furosemide dose, cumulative dose, total days of exposure, and maximum daily dose. We compared dosing between infants born at <32 weeks gestational age (GA) and ≥32 weeks GA.

A total of 18,572 infants had complete dosing data. The median (interquartile value) postnatal age at first exposure was 11 days (4, 26), the median maximum daily dose was 1.0 mg/kg (0.97, 1.6), the median average daily dose was 1.0 mg/kg (0.88, 1.1), and the median cumulative dose was 2.0 mg/kg (1.0, 4.5). The median total duration of exposure was 2 days (1, 4). A total of 177 (1%) infants received ≥4 mg/kg/day of furosemide. Infants born <32 weeks GA were an older age at initial furosemide exposure compared to those born ≥32 weeks GA 19 versus 4 days, p < 0.001.

Most infants received short courses of furosemide within the labeled dosing parameters. Further studies are needed to assess the safety and efficacy of furosemide in the NICU.

The modified Rankin scale (mRS) is the most common assessment tool for measuring overall functional outcome in stroke studies. The traditional way of using mRS face-to-face is time- and cost-consuming. The aim of this study was to test the validity of the Swedish translation of the simplified modified Rankin scale questionnaire (smRSq) as compared with the mRS assessed face-to-face 6 months after a stroke.

Within the ongoing EFFECTS trial, smRSq was sent out to 108 consecutive stroke patients 6 months after a stroke. The majority, 90% (97/108), of the patients answered the questionnaire; for the remaining 10%, it was answered by the next of kin. The patients were assessed by face-to-face mRS by 7 certified healthcare professionals at 4 Swedish stroke centres. The primary outcome was assessed by Cohen’s kappa and weighted kappa.

There was good agreement between postal smRSq, answered by the patients, and the mRS face-to-face; Cohen’s kappa was 0.43 (CI 95% 0.31-0.55), weighted kappa was 0.64 (CI 95% 0.55-0.73), and Spearman rank correlation was 0.82 (p < 0.0001). In 55% (59/108), there was full agreement, and of the 49 patients not showing exact agreement, 44 patients differed by 1 grade and 5 patients had a difference of 2 grades.

Our results show good validity of the postal smRSq, answered by the patients, compared with the mRS carried out face-to-face at 6 months after a stroke. This result could help trialists in the future simplify study design and make multicentre trials and quality registers with a large number of patients more feasible and time-saving.

Endobronchial ultrasound elastography that provides information on tissue stiffness may help distinguish malignant from benign mediastinal and hilar lymph nodes.

In this prospective trial, we assessed the diagnostic value of elastographic images and the interobserver agreement in its evaluation.

Elastographic images from 77 lymph nodes in 65 patients were reviewed by 3 pneumologists. The elastographic image was classified based on the predominant colour predominantly green, intermediary, and predominantly blue. With 2 or 3 interobserver matches, the corresponding elastographic image was correlated with the pathological result obtained from endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and/or other invasive procedures.

All 3 reviewers had agreement in classifying elastographic images in 45% (35/77). Overall, the interobserver agreement among the 3 readers for classifying elastographic pattern was found to be moderate (Fleiss Kappa index = 0.519; 95% CI = [0.427; 0.611]). On cytological/histological evaluation, 55 lymph nodes were malignant and 22 were benign. In classifying „green” as benign and „blue” as malignant, the sensitivity and specificity were 71% (95% CI = [54%; 85%]) and 67% (95%-CI = [35%; 90%]), respectively.

Elastography will not replace invasive EBUS-TBNA due to a moderate interobserver agreement and insufficient sensitivity and specificity. However, elastography will, maybe, present an additional feature to identify malignant lymph nodes in the context of clinical, radiological, and cytological results.

In this study, we used a rat model of retinal detachment (RD) to investigate the effects of transient receptor potential mucolipin 1 (TRPML1) on photoreceptor cells and the underlying mechanism.

An RD model was established by subretinal injection of sodium hyaluronate, and mucolipin synthetic agonist 1 (ML-SA1) and dimethyl sulfoxide (DMSO) were subretinally injected after RD induction. Retinal morphology was observed using haematoxylin-eosin (HE) staining, and the apoptosis of photoreceptor cells was detected by transmission electron microscopy (TEM). Reactive oxygen species (ROS) were examined with a ROS detection kit. The retinal expression levels of TRPML1, the autophagy-related protein microtubule-associated protein 1 light chain 3 (LC3), Beclin1, and cleaved caspase3 were detected by western blotting. The Morris water maze was used to test vision-dependent behaviour.

We found that retinal structure and the outer nuclear layer (ONL) were improved and that the apoptosis of photoreceptor cells was reduced after ML-SA1 injection. The expression of ROS was reduced, and the loss of TRPML1 was inhibited after ML-SA1 treatment. The LC3-II to LC3-I ratio and Beclin1 expression were enhanced, and cleaved caspase3 expression was decreased after ML-SA1 treatment. Treatment with ML-SA1 also improved vision-dependent behaviour.

Our findings suggest that ML-SA1 attenuates photoreceptor apoptosis and improves vision-dependent behavior by activation of autophagy.

Copeptin and nesfatin-1 have recently been identified as novel peptides that play a role in the pathogenesis of obesity-related insulin resistance in adults. However, the relationship between them has not yet been elucidated, and their circulating levels in children with obesity have not been adequately studied. Therefore, the current study aimed to investigate whether their levels are altered in Chinese children with obesity, as well as to determine the correlation of these 2 peptides with each other, with insulin resistance, and with other biochemical parameters.

A total of 156 children were enrolled in this study, including 101 children with obesity and 55 lean controls. Anthropometric parameters and clinical data of all subjects were collected, and circulating tumor necrosis factor-α, adiponectin, leptin, copeptin, and nesfatin-1 levels were measured using ELISA.

Serum copeptin and nesfatin-1 levels were significantly elevated in children with obesity and children with insulin resistance compared to control subjects. In addition, nesfatin-1 and copeptin levels were found to be significantly positively correlated with one another by Pearson’s correlation and partial correlation. In multiple regression analysis using nesfatin-1 or copeptin as the dependent parameter, a significant correlation was observed between nesfatin-1 and copeptin, and associations between each of them with homeostasis model assessment of insulin resistance (HOMA-IR) were detected.

These novel findings shed light on the possible interplay role of these 2 molecules in obesity-related insulin resistance.

Liver reserve affects survival in hepatocellular carcinoma (HCC). Model for End-Stage Liver Disease (MELD) score is used to predict overall survival (OS) and to prioritize HCC patients on the transplantation waiting list, but more accurate models are needed. We hypothesized that integrating insulin-like growth factor 1 (IGF-1) levels into MELD score (MELD-IGF-1) improves OS prediction as compared to MELD.

We measured plasma IGF-1 levels in training (n = 310) and validation (n = 155) HCC cohorts and created MELD-IGF-1 score. Cox models were used to determine the association of MELD and MELD-IGF-1 with OS. Harrell’s c-index was used to compare the predictive capacity.

IGF-1 was significantly associated with OS in both cohorts. Patients with an IGF-1 level of ≤26 ng/mL in the training cohort and in the validation cohorts had significantly higher hazard ratios than patients with the same MELD but IGF-1 >26 ng/mL. In both cohorts, MELD-IGF-1 scores had higher c-indices (0.60 and 0.66) than MELD scores (0.58 and 0.60) (p < 0.001 in both cohorts). Overall, 26% of training and 52.9% of validation cohort patients were reclassified into different risk groups by MELD-IGF-1 (p < 0.001).

After independent validation, the MELD-IGF-1 could be used to risk-stratify patients in clinical trials and for priority assignment for patients on liver transplantation waiting list.

Several measures of blood pressure (BP) variability have been associated with kidney disease and cardiovascular events. Although BP is routinely measured during hospitalization in daily practice, the prognostic impact of in-hospital BP and its variability are uncertain.

A total of 226 participants who underwent elective percutaneous coronary intervention (PCI) for stable coronary artery disease (CAD) were included. BP was measured by trained nurses during the 4-day hospitalization for PCI. BP variability was assessed by standard deviation (SD) and coefficient variation of systolic BP. Estimated glomerular filtration rate (eGFR) was calculated at baseline and follow-up (≥6 months). The cardiovascular end point was defined as a composite of cardiovascular death, acute coronary syndrome, stroke, heart failure hospitalization, and any coronary revascularization.

In-hospital BP was measured 9.5 ± 0.8 times. During a median follow-up period of 1.7 years, mean eGFR change was -1.7 mL/min/1.73 m2 per year, and 35 (15.5%) participants met the cardiovascular end point. Mean systolic BP and SD were negatively correlated with eGFR change. In the receiver operating characteristic curve analysis, SD of systolic BP predicted the cardiovascular end point (AUC 0.63, best cutoff value 14.2 mm Hg, p = 0.003). Kaplan-Meier analysis demonstrated a significantly higher incidence of the cardiovascular end point in patients with SD of systolic BP ≥14.2 mm Hg compared to their counterpart (p = 0.003). A multivariable analysis showed SD of systolic BP as an independent predictor for the cardiovascular end point. When assessed with coefficient variation, BP variability was similarly related to eGFR change and clinical outcomes.

Greater in-hospital BP variability was associated with renal function decline and cardiovascular events in patients with stable CAD.

LincRNA (long intergenic noncoding RNA) has been indicated as a mediator in tumorigenesis of bladder carcinoma. This study was performed to evaluate the role of LINC00460 in bladder carcinoma progression.

Expression levels of LINC00460 in bladder carcinoma tissues and cell lines were analyzed via qRT-PCR. MTT, EdU (5-ethynyl-2′-deoxyuridine) staining, and colony formation assays were utilized to evaluate cell viability and proliferation. The wound healing assay was performed to evaluate bladder cancer cell migration, and the transwell assay was used to evaluate cell invasion. The microRNA (miRNA) target of LINC00460 and the corresponding target gene were validated via the dual luciferase activity assay. The tumorigenic function of LINC00460 was determined via establishment of a xenotransplanted tumor model.

LINC00460 was elevated in bladder carcinoma tissues and cell lines. Elevated LINC00460 was associated with shorter overall survival of bladder carcinoma patients. Overexpression of LINC00460 promotedtherapeutic target for treatment of bladder carcinoma.

Presence of anti-JC-virus antibodies (JCVAbs) is associated with the increased risk of natalizumab (NAT)-related progressive multifocal leukoencephalopathy (PML). Little is known about seroconversion rate and time to seroconversion in relapsing-remitting multiple sclerosis (RRMS) patients treated with NAT in Poland. The aim of the study was to assess the true risk of PML, seroconversion rate, and time to seroconversion in all JCVAb-negative RRMS patients treated with NAT in Poland.

Demographic and clinical data of all Polish RRMS patients treated with NAT reimbursed by National Health Fund (NFZ) were prospectively collected in electronic files using the Therapeutic Programme Monitoring System provided by NFZ. The assessment of JCVAb presence (without collection of JCVAb index value) in serum (Unilabs, STRATIFY JCV anti-JCV antibody ELISA) was done at the beginning of therapy and then repeated every 6 months. The maximum follow-up time was 4 years. In Poland, since 2013, according to the NFZ drug program gative RRMS patients is safe and results in the absence of PML cases. In Poland, JCV seroconversion rate is similar to that observed in other European countries.INTRODUCTION To evaluate the applicability of optical coherence tomography-angiography (OCT-A) for measuring geographic atrophy (GA) areas in age-related macular degeneration (AMD) patients with 'foveal’ and 'no foveal’ sparing disease and compare it to other imaging modalities. METHODS A multimodal imaging protocol was applied, using infrared imaging (IR), fundus autofluorescence (FAF), OCT-A and en-face OCT in 35 eyes of 23 AMD patients with GA. Patients were classified in two groups, with and without foveal sparing disease. GA area measurements for all imaging modalities were compared for each group separately. RESULTS The measured GA area was estimated 6.68 ± 3.18 mm2using IR; 6.99 ± 3.09 mm2 using FAF; 6.56 ± 3.11 mm2 using OCT-A and 6.65 ± 3.14 mm2using en-face OCT. There was no statistically significant difference in GA area between different modalities (p=0.977). When separate analysis was conducted for patients with 'foveal’ and 'no foveal’ sparing disease, although GA measurements in FAF imaging displayed higher numerical values compared to the other modalities, especially in patients with foveal sparing, no statistically significant difference in GA area was found between the different imaging modalities in either group (p=0.816 for foveal sparing; p=0.992 for no foveal sparing group). CONCLUSIONS OCT-A can be reliably used in the assessment of GA in AMD patients with and without foveal sparing disease. For both groups, measurements are comparable to IR, en-face OCT and FAF, despite the fact that the latter recorded larger area of GA, mainly in the foveal sparing cases.For phonons propagating in a crystal at low temperature, we develop a phonon reflection model and an analysis framework to fully understand reflection peaks from underlying physics principles. Our study shows that the specular reflection structure of peaks contains detailed information about properties of the crystal material, and provides a solid quantitative link between phonon theory and experimental signals. For both kinds of experiments that either use crystal as a particle detector or as a target material for study, this analysis provides a novel and essential method to understand the experimental signatures.

High frequency (HF) block can quickly and reversibly stop nerve conduction. We hypothesized HF block at the sciatic nerve would minimize nociception by preventing neuropathic signals from reaching the central nervous system.

Lewis rats were implanted with a constriction cuff and a distal cuff electrode around their right sciatic nerve. Tactile sensitivity was evaluated using the 50% paw withdrawal threshold determined using Chaplan’s method for von Frey monofilaments. Over the course of 49 days, the 50% paw withdrawal threshold was measured 1) before HF block, 2) during HF block (50 kHz, 3 Vpp), and 3) after HF block. Gait was observed and scored before and during block. At end point, HF block efficacy was directly evaluated using additional cuff electrodes to elicit and record compound neural action potentials across the HF blocking cuff.

At days 7 and 14 days post-operation, tactile sensitivity was significantly lower during HF block compared to before and after block (p < 0.005). Additionally, an increase in gait disability was not visually observed during HF block.

HF block can reduce tactile sensitivity in a limb with a neuropthic injury in a rapidly reversible fashion.

However, measurements of the Shubnikov-de Haas oscillations, intended to reveal information about Fermi surfaces, have mostly been carried out in magnetic fields perpendicular to the applied currents. Here, using magnetic fields not only perpendicular but also parallel to the applied currents in a given contact configuration, we investigated the anisotropic magnetotransport and the anisotropic Fermi surface properties of Bi2-xSnxTe3(0 ≤ x ≤ 0.0075) and Bi2Se3. While the magnetotransport properties of Bi2Te3and Bi2Se3were nearly isotropic, Bi1.995Sn0.005Te3exhibited quite anisotropic features. These observations are attributed to the nonparabolicity of the associated bands, which evolved to more anisotropic band structures with Sn concentration. This sensitivity of the band anisotropy was rather unexpected because only a small number of dopants are known to increase disorder levels in the degenerate region. Our approach, using two different magnetic field directions in the measurements of the Shubnikov-de Haas oscillations, is a simple and easily adoptable method for shedding more light on the Fermi surfaces of functional materials.Efficient nucleotide import is critical to fuel the reverse DNA synthesis that takes place within the HIV-1 capsid. However, the mechanism by which the HIV-1 capsid imports nucleotides is presently unclear. In this work, we carry out a series of Brownian diffusion simulations to elucidate the nucleotide import process through the hexamer pores of the HIV-1 capsid. Our simulations reveal a significant role of the electrostatic field in the import process and the mechanism by which deoxynucleoside triphosphates (dNTPs) diffuse through the arginine ring specifically, how IP6s and ATPs, though competing with dNTPs for binding at the pore of the arginine ring, end up accelerating the dNTP import rate by thousands of folds so that it is sufficiently high to fuel the encapsidated DNA synthesis.This study investigated the feasibility of dosimetric measurements using Al2O3C optically stimulated luminescence (OSL) dosimeters during fluoroscopy-guided procedures. The linearity and energy dependence of Al2O3C OSL dosimeters were evaluated, and the air kerma rate at the operator’s position was measured. The response of Al2O3C OSL dosimeters to short, repetitive irradiations was compared to that of long uninterrupted irradiation. The change in response of the Al2O3C OSL dosimeter under automatic exposure rate control (AERC) was evaluated with the use of various thicknesses of polymethyl-methacrylate (PMMA) plates (15-30 cm). The Al2O3C OSL dosimeters could detect 5 µGy and showed good linearity in doses of ≥ 10 µGy (R² 0.997-0.999, p 0.05). Despite a high energy dependence on the low energy beam used in fluoroscopy, the change in relative response of the Al2O3C OSL dosimeter under AERC was within 5.7% depending on the thickness of the PMMA plates. Dosimetric measurement using Al2O3C OSL dosimeters for patients and operators is feasible. However, one should be cautious about high standard deviations when measuring small doses of ≤ 20 µGy using Al2O3C OSL dosimeters. It is essential to perform intensive bleaching before measuring very small doses to minimize pre-irradiation counts.In this study, we employ bulk electronic properties characterization and x-ray scattering/spectroscopy techniques to map the structural, magnetic and electronic properties of (Eu1-xCax)2Ir2O7as a function of Ca-doping. As expected, the metal-insulator transition temperature, TMIT, decreases with Ca-doping until a metallic state is realized down to 2 K. In contrast, the onset of magnetic order at TAFMbecomes decoupled from TMITand (likely short-range) antiferromagnetism persists into the metallic regime. This decoupling is understood as a result of the onset of an electronically phase separated state, the occurrence of which seemingly depends on both synthesis method and rare earth site magnetism. PDF analysis suggests that electronic phase separation occurs without accompanying chemical phase segregation or changes in the short-range crystallographic symmetry while synchrotron x-ray diffraction confirms that there is no change in the long-range crystallographic symmetry. X-ray absorption measurements confirm the Jeff = ½ character of (Eu1-xCax)2Ir2O7. Surprisingly these measurements also indicate a net electron doping, rather than the expected hole doping, indicating a compensatory mechanism. Lastly, XMCD measurements show a weak Ir magnetic polarization that is largely unaffected by Ca-doping.Smokers are exposed to more than 6000 (toxic) smoke components including volatile organic compounds (VOCs). In this study VOCs levels in headspace of blood and exhaled breath, in the mainstream smoke of three types of cigarettes of one brand varying in declared tar, nicotine and carbon monoxide (TNCO) yields are investigated. The objective was to identify whether VOC levels correlate with TNCO yields of cigarettes smoked according to ISO 3308. Our data show that smoking regular and low-TNCO cigarettes result in comparable levels of VOCs in blood and exhaled breath. Hence, declared TNCO-yields as determined with the ISO 3308 machine smoking protocol are irrelevant for predicting VOC exposure upon human smoking. Venous blood and exhaled breath were sampled from 12 male volunteers directly before and 10 min after smoking cigarettes on 3 d (day 1 Marlboro Red (regular), day 2 Marlboro Prime (highly ventilated, low-TNCO), day 3 Marlboro Prime with blocked filter ventilation (taped)). Upon smoking, the levels of toluene, ethylbenzene, m/p-xylene, o-xylene, and 2,5-dimethylfuran in both headspace of venous blood and exhaled breath increase within the same range for all three cigarette types smoked. However, no strong correlation was found between VOC levels in exhaled breath and VOC levels in headspace of blood because of variations between the individual smoking volunteers. More research is required in order to use exhaled breath sampling as a non-invasive quantitative marker for volatile toxicants from cigarette smoke exposure of different brands.Ketone testing is an important element of the self-management of illness in type 1 diabetes. The aim of the present study was to see if a breath test for acetone could be used to predict quantitatively the levels of the ketone betahydroxybutyrate in the blood of those with type 1 diabetes, and thus be used as an alternative to capillary testing for ketones. Simultaneous capillary ketones and breath acetone were measured in 72 individuals with type 1 diabetes attending a diabetes clinic and on 9 individuals admitted to hospital with diabetic ketoacidosis. Capillary blood measurements ranged from 0.1 mmol l-1 (the lower limit of the ketone monitor) to over 7 mmol l-1, with breath acetone varying between 0.25 and 474 parts per million by volume. The two variables were found to be correlated and allowed modelling to be carried out which separated breath acetone levels into three categories corresponding to normal, elevated and 'at risk’ levels of blood ketones. The results on this limited set of participants suggest that a breath acetone test could be a simple, non-invasive substitute for capillary ketone measurement in type 1 diabetes.

The outbreak of coronavirus SARS-COV2 affected more than 180 countries necessitating fast and accurate diagnostic tools. Reverse transcriptase polymerase chain reaction (RT-PCR) has been identified as a gold standard test with Chest CT and Chest Radiography showing promising results as well. However, radiological solutions have not been used extensively for the diagnosis of COVID-19 disease, partly due to radiation risk. This study aimed to provide quantitative comparison of imaging radiation risk versus COVID risk.

The analysis was performed in terms of mortality rate per age group. COVID-19 mortality was extracted from epidemiological data across 299,004 patients published by ISS-Integrated surveillance of COVID-19 in Italy. For radiological risk, the study considered 659 Chest CT performed in adult patients. Organ doses were estimated using a Monte Carlo method and then used to calculate Risk Index that was converted into an upper bound for related mortality rate following NCI-SEER data.

COVID-19 morest CT mortality rates showed different magnitudes and trends across age groups. In higher ages, the risk of COVID-19 far outweighs that of radiological exams. Based on risk comparison alone, Chest Radiography and CT for COVID-19 care is justified for patients older than 20 and 30 years old, respectively. Notwithstanding other aspects of diagnosis, the present results capture a component of risk consideration associated with the use of imaging for COVID. Once integrated with other diagnostic factors, they may help inform better management of the pandemic.A plasmonic nanopore sensor enabling detection of bimodal optical and electrical molecular signatures was fabricated and tested for its ability to characterize low affinity ligand-receptor interactions. This plasmonic nanosensor uses self-induced back-action (SIBA) for optical trapping to enable SIBA-actuated nanopore electrophoresis (SANE) through a nanopore located immediately below the optical trap volume. A natural killer (NK) cell inhibitory receptor heterodimer molecule CD94/NKG2A was synthesized to target a specific peptide-presenting Qa-1b Qdm ligand as a simplified model of low-affinity interactions between immune cells and peptide-presenting cancer cells that occurs during cancer immunotherapy. A cancer-irrelevant Qa-1b GroEL ligand was also targeted by the same receptor as a control experiment to test for non-specific binding. The analysis of different pairs of bimodal SANE sensor signatures enabled discrimination of ligand, receptor and their complexes and enabled differentiating between specific and non-specific ligand interactions. We were able to detect ligand-receptor complex binding at concentrations over 500 times lower than the free solution equilibrium binding constant (K D ). Additionally, SANE sensor measurements enabled estimation of the fast dissociation rate (k off) for this low-affinity specific ligand-receptor system, previously shown to be challenging to quantify with commercial technologies. The k off value of targeted peptide-presenting ligands is known to correlate with the subsequent activation of immune cells in vivo, suggesting the potential utility of the SANE senor as a screening tool in cancer immunotherapy.The physiological roles of isoprene, which is one of the many endogenous volatile organic compounds contained in exhaled breath, are not well understood. In recent years, exhaled isoprene has been associated with the skeletal muscle. Some studies have suggested that the skeletal muscle produces and/or stores some of the isoprene. However, the evidence supporting this association remains sparse and inconclusive. Furthermore, aging may affect breath isoprene response because of changes in the skeletal muscle quantity and quality. Therefore, we investigated the association between the breath isoprene excretion ([Formula see text]) and skeletal muscle mass in young (n = 7) and old (n = 7) adults. The participants performed an 18 min cycling exercise after a 3 min rest. The workload corresponded to an intensity of 30% of the heart rate reserve, as calculated by the Karvonen formula. The exhaled breath of each participant was collected during the exercise test. We calculated [Formula see text] from the product minute ventilation and isoprene concentration and, then, investigated the relationships between [Formula see text] and muscle mass, which was measured by multi-frequency bioelectrical impedance analysis. Importantly, muscle mass persisted as a significant determinant that explained the variance in [Formula see text] at rest even after adjusting for age. Furthermore, the muscle mass was a significant determinative factor for [Formula see text] response during exercise, regardless of age. These data indicated that skeletal muscle mass could be one of the determinative factors for [Formula see text] during rest and response to exercise. Thus, we suggest that the skeletal muscle may play an important role in generating and/or storing some of the endogenous isoprene. This new knowledge will help to better understand the physiological functions of isoprene in humans (Approval No. 20190079).Two-dimensional nanolayers have found increasingly widespread applications in modern flexible electronic devices. Their adhesion with neighbouring layers can significantly affect the mechanical stability and the reliability of those devices. However, the measurement of such adhesion has been a great challenge. In this work, we develop a new and simple methodology to measure the interfacial adhesion between a mica nanolayer (MNL) and a single-layer graphene (SLG) supported by a SiO2 substrate. The method is based on the well-known Obreimoff method but integrated with innovative nanomanipulation and profile measuring approaches. Our study shows that the adhesion energy of MNLs on the SLG/SiO2 substrate system is considerably lower than that on the SiO2 substrate alone. Quantitative analyses reveal that the wrinkles formed on the SLG can considerably lower the adhesion. This outcome is of technological value as the adhesion maybe tailored by controlling the wrinkle formation in the graphene layer in a flexible electronic device.Thiol modification of beta cyclodextrin (β-CD) was carried out using thiourea, which served as a thiol donor. The chemical reaction was mediated using HCl. Polymer prepared via thiolation was further subjected to physicochemical and biocompatible analysis. Acute oral toxicity and compatibility was determined in albino rats. Furthermore, compressed tablets of ticagrelor (TCG) were prepared using modified and unmodified polymers and evaluated via various quality control tests. Thiolation was successfully achieved and confirmed by the FTIR scan, as a significant corresponding peak was observed at 2692 cm-1 wavenumber, demonstrating the attachment of -SH group. In vivo analysis has confirmed the safe use of β-CD, as none of the vital organs showed any kind of toxic effects. Dissolution studies revealed that Tβ-CD was able to release 96.62% of the drug within 1 h of the study, hence providing an immediate release. Conclusively, a thiol moiety was successfully attached to the polymeric backbone and was found safe to be used as a pharmaceutical excipient.In this study, we used murine chondrocytes as an in vitro model and mice exhibiting destabilization of the medial meniscus (DMM) as an in vivo model to investigate the mechanisms through which S-allyl cysteine (SAC) alleviates osteoarthritis (OA). SAC significantly reduced apoptosis and senescence and maintained homeostasis of extracellular matrix (ECM) metabolism in tert-butyl hydroperoxide (TBHP)-treated chondrocytes. Molecular docking analysis showed a -CDOCKER interaction energy value of 203.76 kcal/mol for interactions between SAC and nuclear factor erythroid 2-related factor 2 (Nrf2). SAC increased the nuclear translocation of Nrf2 and activated the Nrf2/HO1 signaling pathway in TBHP-treated chondrocytes. Furthermore, Nrf2 knockdown abrogated the antiapoptotic, antisenescence, and ECM regulatory effects of SAC in TBHP-treated chondrocytes. SAC treatment also significantly reduced cartilage ossification and erosion, joint-space narrowing, synovial thickening and hypercellularity in DMM model mice. Collectively, these findings show that SAC ameliorates OA pathology in TBHP-treated chondrocytes and DMM model mice by activating the Nrf2/HO1 signaling pathway.
