Complement receptor 3 (CD11b/CD18) is an important receptor that mediates adhesion, phagocytosis and chemotaxis in various immunocytes. The conidia of the medically-important pathogenic fungus, Aspergillus fumigatus can be internalized into alveolar epithelial cells to disseminate its infection in immunocompromised host; however, the role of CR3 in this process is poorly understood. In the present study, we investigated the potential role of CR3 on A. fumigatus internalization into type II alveolar epithelial cells and its effect...

Adhesives with properties of low-temperature and water-resistance are important in manufacturing. In this work, dopamine hydrochloride (DA), containing catechol groups, was introduced into the polymer by covalent grafting to obtain water-resistant films. Films with low-temperature and water-resistance properties were obtained through layer-by-layer assembly of branched polyethyleneimine (bPEI) and chemically cross-linked hyaluronate (HA)-DA (denoted HA-D). The film surfaces were wetted with moisture generated from low-temperature pretreatment, and the resulting films, named as bPEI/HA-D multilayer films, could...

Heat stress is an environmental challenge that reduces plant productivity and growth. Plants have developed corresponding mechanisms to survive this adverse environmental stress. To demonstrate the mechanisms of how plants adapt to the environmental challenge, the heat response experiments involving Arabidopsis thaliana were retrieved from the GEO database. After quantile normalization of the GEO raw data, the differentially expressed genes (DEGs) in response to heat stress were identified by robust rank aggregation (RRA) algorithm, including...

Hepatitis B virus (HBV) middle surface antigen (MHBs) mutation or deletion occurs in patients with chronic HBV infection. However, the functional role of MHBs in HBV infection is still an enigma. Here, we reported that 7.33% (11/150) isolates of CHB patients had MHBs start codon mutations compared with 0.00% (0/146) in acute hepatitis B (AHB) patients. Interestingly, MHBs loss accounted for 11.88% (126/1061) isolates from NCBI GenBank, compared with 0.09% (1/1061) and 0.00% (0/1061) for...

In the present study, a total of 1102304 serum samples were collected to detected human brucellosis between the years 2012 and 2016 in Inner Mongolia. Overall, an average of 3.79% anti-Brucella positive in Inner Mongolia was presented but the range of positive rates were among 0.90 to 7.07% in 12 regions. Seroprevalence of human brucellosis increased gradually from 2012 to 2016. However, the incidence rate of human brucellosis showed a declining trend. One hundred and...

Snap bean (Phaseolus vulgaris L.) is low in fat and high in nutrients; however, it also contains toxigenic factors such as phytohemagglutinin (PHA), which is poisonous to humans. Here, we aimed to determine the distribution of PHA in natural populations of snap bean by analyzing a candidate gene (PHA-E) related to PHA content. Functional genome-wide single nucleotide polymorphisms (SNPs) were then scanned to identify SNPs related to PHA content. A total of 150 snap bean...

Blood pressure (BP) variability is highly correlated with cardiovascular and kidney outcomes in patients with chronic kidney disease (CKD). However, appropriate BP targets in patients with CKD remain uncertain. We searched PubMed, Embase, and the Cochrane Library for randomized controlled trials (RCTs) of CKD patients who underwent intensive BP management. Kappa score was used to assess inter-rater agreement. A good agreement between the authors was observed to inter-rater reliability of RCTs selection (kappa = 0.77;...

The therapeutic effects of tacrolimus (TAC) versus cyclophosphamide (CTX) were not fully illustrated for patients with idiopathic membranous nephropathy (IMN). The PubMed, EmBase, Cochrane library, and CNKI were systematically searched throughout March 2020 for randomized controlled trials evaluating the therapeutic effects of TAC versus CTX for IMN patients treated with steroids. The pooled relative risks (RRs) and weighted mean differences (WMDs) with 95% confidence intervals (CIs) were calculated using the random-effects model. Twelve trials recruited...
