Depression and anxiety of medical students at Kunming Medical University during COVID-19: A cross-sectional survey.

An isolation strategy was used to control the transmission and rapid spread of COVID-19 in Yunnan. As a result, students were supposed to stay at home and disrupted their outside activities. It led to a detrimental influence on students' mental health.

Deletion of YJL218W reduces salt tolerance of Saccharomyces cerevisiae.

The YJL218W open reading frame may be involved in peroxisomal biogenesis. However, whether it mediates salt tolerance is unclear. We found that after knockdown of YJL218W in Saccharomyces cerevisiae (S.

Transcriptome Analysis Reveals that MAPK Signaling Pathway Mediates Salt Tolerance of YMR253C ORF in Saccharomyces cerevisiae.

The YMR253C open reading frame encodes a membrane protein that is highly expressed in NaCl-resistant Saccharomyces cerevisiae mutants. Whether it mediates NaCl tolerance is unclear. By knocking out YMR253C in S.

Depressive Symptoms, Sleep Quality and Diet During the 2019 Novel Coronavirus Epidemic in China: A Survey of Medical Students.

The psychological condition of medical students may be influenced by the 2019 novel coronavirus (COVID-19) outbreak. This study investigated the prevalence and influencing factors of depressive symptoms, poor sleep quality and poor diet in students at Kunming Medical University during the early part of the COVID-19 outbreak. A cross-sectional study was used from a questionnaire survey in February 2020.

The Ubiquitin Proteasome System and Skin Fibrosis.

The ubiquitin proteasome system (UPS) is a highly conserved way to regulate protein turnover in cells. The UPS hydrolyzes and destroys variant or misfolded proteins and finely regulates proteins involved in differentiation, apoptosis, and other biological processes. This system is a key regulatory factor in the proliferation, differentiation, and collagen secretion of skin fibroblasts.

Ginsenoside Rb1 exerts antidepressant-like effects via suppression inflammation and activation of AKT pathway.

Depression-like behaviors caused by chronic stress are related to inflammation and microglia activation. Antidepressant therapy may contribute to inhibiting inflammation responses and microglia activation. Ginsenoside Rb1 (GRb1) is known to display antidepressant-like effect on chronic unpredictable mild stress-induced depressive rats.

Panax notoginsenoside Rb1 Restores the Neurotrophic Imbalance Following Photothrombotic Stroke in Rats.

Mature brain-derived neurotrophic factor (mBDNF) has neuroprotection in cerebral ischemia. Conversely, the precursor of brain-derived neurotrophic factor (proBDNF) has the opposite function to its mature form, inducing apoptosis. However, whether the neuroprotection of Panax notoginsenoside Rb1 (PNS-Rb1) on ischemic stroke is due to, at least partially, its modulation of suppressing proBDNF/P75NTR/sortilin or upregulation of mBDNF is not clear.

[Relationship between cytoplasmic phospholipase A2 and nuclear factor κB in one lung ventilation-induced lung injury in rabbits].

Objective: To elucidate the mechanisms of up regulated expression of cytoplasmic phospholipase A2 (CPLA2) induced by one lung ventilation (OLV) by investigating the interactions between nuclear factor kappaB (NF-κB) and C-PLA2.

Methods: Forty-eight healthy Japanese white rabbits were randomized into control group, solvent treatment group (group S), NF-κB inhibitor (PDTC)/solvent treatment group ( group PS), C-PLA2 inhibitor (AACOCF3)/solvent treatment group (group AS), OLV group (group O), solvent treatment plus OLV group (SO group), NFκB inhibitor (PDTC)/solvent treatment plus OLV group (group PSO) and CPLA2 inhibitor (AACOCF3)/solvent treatment plus OLV group (group ASO). ELISA was used to detect arachidonic acid (AA) content in the lung tissues, and NFκB and CPLA2 expressions were detected by Western blotting and quantitative PCR.

Effects of delaying transplanting on agronomic traits and grain yield of rice under mechanical transplantation pattern.

A delay in the mechanical transplantation (MT) of rice seedlings frequently occurs in Huanghuai wheat-rice rotation cropping districts of China, due to the late harvest of wheat, the poor weather conditions and the insufficiency of transplanters, missing the optimum transplanting time and causing seedlings to age. To identify how delaying transplanting rice affects the agronomic characteristics including the growth duration, photosynthetic productivity and dry matter remobilization efficiency and the grain yield under mechanical transplanting pattern, an experiment with a split-plot design was conducted over two consecutive years. The main plot includes two types of cultivation: mechanical transplanting and artificial transplanting (AT).

The null polymorphism of the GSTM1/T1 gene is not associated with susceptibility to systemic lupus erythematosus: a meta-analysis.

Previous studies have suggested that the null polymorphism of the glutathione S-transferases M1/T1 (GSTM1/T1) gene may be associated with the risk of developing systemic lupus erythematosus (SLE). We further explored this potential association using a meta-analysis. A systematic literature search was carried out in the scientific literature databases and we used odds ratios (OR) and 95 % confidence intervals (CIs) to evaluate the strength of this association.
