Endothelial cells (ECs) play a critical role in health and disease due to their widespread distribution and unique location. Although ECs are not regarded as classical immune cells, they actively participate in innate immune and inflammatory responses. EC function is affected by exogenous activators (i.e., infectious agents) and endogenous triggers (i.e., damage-associated molecular pattern molecules (DAMPs) released by stressed or injured cells). Toll-like receptors (TLRs) can recognize both infectious agents and DAMPs and play a key role in activating innate mechanisms in ECs. Endothelial dysfunction (EDF) may lead to tissue damage in various inflammatory and autoimmune diseases through TLRs. This review summarizes the current knowledge about the role of TLRs in a variety of EDF-related conditions, including autoimmunity and graft rejection, cancer, cardiovascular diseases, diabetes and related complications, ischemia and related injuries, and sepsis.The TEMPO/NaBr/NaClO system was used to modify konjac glucomannan and prepare β-1,4-linked D-mannuronic/glucuronic acid oligosaccharides. The impact of oxidant amount on the degree of oxidation, molecular weight, terminal structure and the ratio of sugar units were systematically investigated. Mannoses were transformed to mannuronic acids quantitatively, while some glucose were transformed to glucuronic acids, some degraded. The unspecific oxidation causes strong degradation of konjac glucomannan sugar chains. Multiple terminal structures were observed in the oxidized KGM products. According to those observations, the oxidation pattern of konjac glucomannan with the TEMPO/NaBr/NaClO system was speculated. It is suggested that the axial hydroxyl group at position 2 in mannose might form a hydrogen bond with the oxygen on the sugar ring. It would against the unspecific oxidation. While, both specific and unspecific oxidations were observed at glucose units with an equatorial hydroxyl group at position 2, and the degradation occurs mostly on glucose during the oxidation.Gastric ulcer is a common frequent clinical problem affecting all age and gender. This work aims to compare between the therapeutic effects of stem cell derived exosomes, stem cells conditioned medium and omeprazole on the healing of gastric ulcer model. Fifty rats were, assigned into 5 groups; control, gastric ulcer, omeprazole-treated, conditioned medium- treated, and exosomes-treated groups. Gastric ulcer was induced by aspirin dissolved in 1% carboxymethyl cellulose at a daily dose of 200 mg/kg for 5 consecutive days. Stomach specimens were obtained for histological, biochemical, and immunohistochemical assessments. The gastric ulcer group revealed widening of the fundic glands lumen containing, exfoliated dead cells. There was a remarkable distortion of the normal histological structure of the gastric mucosa with surface lining epithelial cell sloughing, vascular congestion and inflammatory cell infiltration. Both exosomes and conditioned medium treatments ameliorated almost all of the histopathological changes. Interestingly, the healing effect of exosomes was greater because it restored the histological architecture of gastric mucosa to nearly normal. In conclusion, this work may pave the future for using stem cell derived exosomes as a more convenient and effective adjuvant therapy in gastric ulcer.Astaxanthin (AX) is a potent antioxidant with increasing biotechnological and commercial potential as a feed supplement, and gives salmonids and crustaceans their attractive characteristic pink color. The red yeast Phaffia rhodozyma naturally produces AX as its main fermentation product but wild-type strains and those previously generated through classical random mutagenesis produce low yields of AX. Existing strains do not meet commercial economic requirements, fundamentally due to a lack of understanding of the underlying mechanisms and genotype-phenotype associations regarding AX production in P. rhodozyma. In the present study, screening of P. rhodozyma CBS 6938 mutant strains generated through chemical and ultra violet radiation mutagenesis delivered increased AX production yields that were then maximized using culture media optimization and fed-batch culture kinetic modeling. The whole genomes of the wild-type and eight increased production strains were sequenced to identify genomic changes. The selected strains produced 50-fold more AX than the wild-type strain with a total biomass of around 100 gDCW/L and a carotenoid production of 1 g/L. Genomic variant analyses found 368 conserved mutations across the selected strains with important mutations found in protein coding regions associated with regulators and catalysts of AX precursors in the mevalonate pathway, the electron transport chain, oxidative stress mechanisms, and carotenogenesis.The objective of this study was to investigate predictors of concussion recovery in children (5-12) versus adolescents (13-18) while identifying economic and demographic disparities in post-concussion care at a tertiary referral concussion clinic versus emergency department (ED). Race and insurance status were recorded for patients presenting to the concussion clinic (724) and ED (1,160) with an ICD-10 concussion diagnosis between 2018 and 2019. Secondly, a subset of patients from the concussion clinic group were included for retrospective cohort review based on documented recovery data. Overall, the concussion clinic saw more Caucasian patients (66.7%) than the ED (56.8%). Concussion clinic patients were more likely to have Private insurance than ED patients (67.2% vs. 55.3%) and less likely to have Medicaid and Self pay (p less then 0.001). Children were more likely to be hospitalized after concussion diagnosis than adolescents (40.8% vs. 24.4%, p = 0.006). Attending public school was associated with a 1.8 times greater hazard ratio (HR) for shorter time to recovery compared to attending private school. Additionally, presence of a diagnosed psychiatric disorder was associated with a HR of 0.5, indicating a longer time to recovery (p less then 0.001) than patients without a disorder. The present findings may support limitations on contact sports participation in young children given their higher hospitalization rate after concussion. Additionally, the study highlights potential barriers to care amongst youth concussion patients with those seen in specialized concussion clinics more likely to be White and have private insurance.

Survivorship care plan helps improve the continuity of care and manage ongoing pain that affects up to 46% of cancer survivors by promoting health behaviors, including physical activity. However, perceived discrimination may decrease the likelihood of cancer survivors participating in physical activities and negatively influence their pain status. Thus, this study aimed to examine the mediating role of physical activity and perceived discrimination in the relationship between receiving a survivorship care plan and cancer pain.

This cross-sectional, correlational study utilized data from the 2012-2019 Behavioral Risk Factor Surveillance System. Analyses accounted for the complex survey design. Logistic regression was utilized to analyze the association among survivorship care plans, discrimination, physical activity, and pain. Generalized structural equation modeling was conducted to test a hypothesized model in which survivorship care plans and discrimination affect physical activity, and subsequently influence pain status.

Forty-two and 81% of survivors reported receiving treatment summaries and follow-up care plans, respectively, and 8% experienced cancer pain. After controlling for covariates, the highest discrimination quintile was three times more likely to report cancer pain than the lowest quintile. While receiving follow-up care plans was positively related to cancer pain, respondents in the third- to fifth- quintiles were less likely to report cancer pain when receiving follow-up care plans than the first quintile respondents. Physical activity mediated the association between discrimination and cancer pain.

Reverse relationships between receiving follow-up care plans and cancer pain existed; however, discrimination and physical activity mediated these relationships.

Recent improvements in survival following a diagnosis of cancer have led to an increase in second primary cancers (SPCs) worldwide. Their aetiology remains largely unknown with a large proportion believed to be related to modifiable lifestyle factors. We conducted a systematic review and meta-analysis of published data that evaluated an association between cigarette smoking and risk of SPC. Studies were identified by searching Medline, Web of Science, CINAHL (Cumulative Index to Nursing and Allied Health Literature) and Scopus databases through March 2021 using broad search criteria. A meta-analysis was performed to derive pooled relative risks (RRs) for SPC defined a priori as smoking-related based on current evidence (lung, upper aero-digestive tract, stomach, pancreas, colorectum, liver, kidney, ureter, bladder and acute myeloid leukaemia). Eleven cohort studies and ten case-control studies met the eligibility criteria for review. Thcaused by smoking.Understanding the complicated emulsion microstructures by microscopic images will help to further elaborate their mechanisms and relevance. The formidable goal of the classification and quantification of emulsion microstructure appears difficult to achieve. However, object detection algorithm in deep learning makes it feasible. This paper reports a new technique for evaluating Pickering emulsion properties through classification and quantification of the emulsion microstructure by object detection algorithm. The trained neural network models characterize the emulsion droplets by distinguishing between different individual emulsion droplets and morphological mechanisms from numerous microscopic images. The quantified results of the emulsion droplets presented in this study, provide details of statistical changes at different concentrations of the Pickering interface and storage temperatures enabling elucidation of the mechanisms involved. This methodology provides a new quantitative and statistical analysis of emulsion microstructure and properties.Calcium has long been recognized as a preeminent signaling molecule in plants with staggeringly diverse functions. The central mystery has therefore been how a single ion species can fulfill distinct functions while maintaining specificity and fidelity. Part of the answer lies in calcium being the most heavily controlled element in the cytosol, with dedicated transporters for sequestration into the apoplasm and intracellular stores. Controlled release of calcium into the cytosol by ion channels is the initiating step in signal transduction. Calcium-permeable ion channels are therefore important research targets. Recent studies have identified previously unknown channels, revealed atomic structures, and pinpointed locations of channels to specific cells and membranes. Here, we highlight key findings, transformative technologies, and pathways for further discovery.
