We conclude that substantial variation in antibody generation against coronavirus proteins will influence interpretations of serologic data in the clinical and veterinary settings.Oral lichen planus (OLP) is a common chronic inflammatory disease affecting the oral mucosa. The pathogenesis of OLP is incompletely understood but is thought to be related to the immune system. As the oral cavity is a major reservoir and transmission gateway for bacteria, viruses, and fungi, the microbial composition of the oral cavity could play a role in the pathogenesis of OLP. However, limited by analytic technology and knowledge of the microbial community in the oral cavity, it is not yet clear which pathogens are associated with OLP. Next generation sequencing (NGS) is a powerful tool to identify pathogens for many infectious diseases. In this study, we compared the host cell gene expression profiles and the microbial profiles between OLP patients and matched healthy individuals. We identified the activation of the hepatocyte nuclear factor alpha (HNF4A) network in OLP patients and potential pathogens, including Corynebacterium matruchotii, Fusobacterium periodonticum, Streptococcus intermedius, Streptococcus oralis, and Prevotella denticola. Prevotella denticola is capable of activating the HNF4A gene network. Our findings shed light on the previously elusive association of OLP with various diseases like hepatitis, and indicate that OLP is a T-helper type 17 (Th17) mediated mucosal inflammatory process. The identified molecular pathways and microbes could be used to inform future investigations into OLP pathogenesis and to develop novel therapeutics for OLP treatment.In eukaryotes, the MAP kinase signaling pathway plays pivotal roles in regulating the expression of genes required for growth, development, and stress response. Here, we deleted the mpkB gene (AFLA_034170), an ortholog of the Saccharomyces cerevisiae FUS3 gene, to characterize its function in Aspergillus flavus, a cosmopolitan, pathogenic, and aflatoxin-producing fungus. Previous studies revealed that MpkB positively regulates sexual and asexual differentiation in Aspergillus nidulans. In A. flavus, mpkB deletion resulted in an approximately 60% reduction in conidia production compared to the wild type without mycelial growth defects. Moreover, the mutant produced immature and abnormal conidiophores exhibiting vesicular dome-immaturity in the conidiophore head, decreased phialide numbers, and very short stalks. Interestingly, the ΔmpkB mutant could not produce sclerotia but produced aflatoxin B1 normally. Taken together, these results suggest that the A. flavus MpkB MAP kinase positively regulates conidiation and sclerotia formation but is not involved in the production of secondary metabolites such as aflatoxin B1.Tai Chi, combined with Thera-band (TCTB) exercise may be associated with an improvement in health where it increases physical fitness, improves psychological well-being, and decreases pain. This paper aimed to determine the feasibility of TCTB exercise in older sedentary office workers. Forty office workers aged over 55 years participated in a pilot randomized controlled trial (i.e., 12-week TCTB exercise or Tai Chi exercise only). Feasibility of the TCTB exercise approach was ascertained through the recruitment and enrolment rate, acceptability of the study intervention by participants including retention and adherence rates, participants' learning process, the appropriateness of data collection as well as the participants' evaluation of the intervention. Recruitment took longer than planned, with a low recruitment rate of 2.0% (42/2020), but a high enrolment rate of 95.2% (40/42). Docetaxel Thirty-one participants (i.e., 77.5%) completed the intervention. Of those who completed the trial, the overall average attendance was reported as 85.2%; 84.7% in the TCTB group and 85.7% in the Tai Chi only group. A total of 58.3% of participants (n = 21) could independently practice the TCTB or Tai Chi exercise motions at the end of the learning stage. There were no missing data except for the nine participants who withdrew during the intervention. No adverse events or effects were reported, and all participants were satisfied with the 12-week exercise intervention. Results support the feasibility of a large-scale randomized controlled trial to explore the efficacy of a TCTB program for improving health in older sedentary office workers.The recent Kidney Disease Outcomes Quality Initiative (K-DOQI) guidelines suggest an early start of protein restriction, raising issues on willingness to change dietary habits. The aim of this exploratory real-life study was to report on a test of dietary products (protein-free, not previously available in France) in a large, mainly elderly, chronic kidney disease (CKD) population (220 patients, median age 77.5 years, Charlson comorbidity index (CCI) seven, malnutrition inflammation score (MIS) five, estimated glomerular filtration rate (eGFR) 26 mL/min), also as a means to tailor further implementation strategies. Forty-nine patients (22.28%) were considered to be poor candidates for the trial (metabolically unstable or with psychological, psychiatric or logistic barriers); of the remaining 171, 80.70% agreed to participate. Patients to whom the diet was not proposed had lower eGFR and higher comorbidity (eGFR 21 vs. 27 p = 0.021; MIS six vs. four p less then 0.001). Patients who refused were 10 years older than those who accepted (83 vs. 73 years p less then 0.001), with a higher CCI (eight vs. seven p = 0.008) and MIS (five vs. four p = 0.01). In the logistic regression, only age was significantly associated with refusal to participate (Odds ratio (OR) 5.408; 95% CI 1.894 to 15.447). No difference was found according to low/intermediate/high frequency of weekly use of protein-free food. Our study suggests that most of the patients are ready to test new diet approaches. Only old age correlated with refusal, but frequency of implementation depended on individual preferences, underlying the importance of tailored approaches to improve adherence.This study examined the relationship between gratitude and subjective well-being (life satisfaction, hope, and positive and negative affect) with individual demographic background (i.e., age, education level, perceived economic status, and religious affiliation) in a sample of 761 Korean adults participated from five universities in South Korea. Specifically, gratitude was still an essential element for the subjective well-being of Korean adults, although the meaning of gratitude under Confucian culture implies indebtedness and obligation. The relationship between gratitude and subjective well-being did not differ by gender. Implications for the subjective well-being of Koreans are discussed.
