Daidzein stimulates fatty acid-induced fat deposition in C2C12 myoblast cells via the G protein-coupled receptor 30 pathway

Chengjian Zhou, Ping Li, Meihong Han & Xuejun Gao
Fat deposition in skeletal muscle is an important aspect of improving meat quality. Isoflavones can promote animal anabolism, but whether and how they regulate muscle fat deposition remain largely unclear. In this study, we explored the role and corresponding molecular mechanism of one of the major isoflavones, daidzein, in fat deposition in C2C12 myoblast cells. In the absence of fatty acids (FAs), daidzein did not promote triglyceride synthesis and lipid droplet formation in cells but...

Personalized Policy Learning using Longitudinal Mobile Health Data

Xinyu Hu, Min Qian, Bin Cheng & Ying Kuen Cheung
Personalized policy represents a paradigm shift from one-decision-rule-for-all users to an individualized decision rule for each user. Developing personalized policy in mobile health applications imposes challenges. First, for lack of adherence, data from each user are limited. Second, unmeasured contextual factors can potentially impact on decision making. Aiming to optimize immediate rewards, we propose using a generalized linear mixed modeling framework where population features and individual features are modeled as fixed and random effects, respectively,...

Objectives To estimate the attack rates, and identify the risk factors of COVID-19 infection. Methods Based on a retrospective cohort study, we investigated 11,580 contacts of COVID-19 cases in Guangdong Province from January 10 to March 15, 2020. All contacts were tested by RT-PCR to detect their infection of SARS-COV-2. Attack rates by characteristics were calculated, and logistic regression was used to estimate the risk factors of infection for COVID-19. Results A total of 515...

Corticosteroid prevents COVID-19 progression within its therapeutic window: a multicenter, proof-of-concept, observational study.

Background: Critically ill patients with COVID-19 are of grave concern. Those patients usually underwent a stage of excessive inflammation before developing acute respiratory distress syndrome. In this study, we test the hypothesis that short-term, low-to-moderate-dose corticosteroids would benefit patients when used in the early phase of excessive inflammation namely, the therapeutic window. Methods: Among a Shanghai cohort and a validation cohort, we enrolled COVID-19 patients showing marked radiographic progression. Short-term, low-to-moderate-dose corticosteroids were considered for...

Silk fibroin hydrogel as mucosal vaccine carrier: induction of gastric CD4+TRM cells mediated by inflammatory response induces optimal immune protection against Helicobacter felis

Chupeng Hu, Wei Liu, Ningyin Xu, An Huang, Zhenxing Zhang, Menghui Fan, Guojing Ruan, Yue Wang, Tao Xi & Yingying Xing
Tissue-resident memory T (TRM) cells, located in the epithelium of most peripheral tissues, constitute the first-line defense against pathogen infections. Our previous study reported that gastric subserous layer (GSL) vaccination induced a “pool” of protective tissue-resident memory CD4+T (CD4+TRM) cells in the gastric epithelium. However, the mechanistic details how CD4+TRM cells form in the gastric epithelium are unknown. Here, our results suggested that the vaccine containing CCF in combination with Silk fibroin hydrogel (SF) broadened...
