Molecular mechanism of regulating tat protein expression of pingganjiedu TCM in the treatment of AIDS based on network pharmacology.

AIDS is a serious disease with impaired immune function caused by human immunodeficiency virus (HIV) infection. The treatment of AIDS has always been the focus of global scientific research, and Tat protein is a key regulatory protein in the process of HIV infection. Its high expression is closely related to virus replication, disease progression, etc.

Resveratrol alleviates salivary gland dysfunction induced by ovariectomy in rats.

Resveratrol (Res), found abundant in many medicinal plants, exerts multiple biological functions in the body, including anti-inflammatory, antioxidant, and anti-aging properties. Xerostomia is a major symptom of salivary gland dysfunction in menopausal women, which significantly compromises the quality of life. Here, we investigated the effect of Res on estrogen deficiency-induced salivary gland dysfunction in rats.

Bacillus amyloliquefaciens BLCC1-0238 Can Effectively Improve Laying Performance and Egg Quality Via Enhancing Immunity and Regulating Reproductive Hormones of Laying Hens.

In this study, we sought to evaluate the effects of dietary Bacillus amyloliquefaciens (B. amyloliquefaciens) BLCC1-0238 supplementation on laying performance, egg quality, antioxidant enzyme activities, reproductive hormone, and immunity of laying hens. A total of 240 Hy-Line Brown laying hens (28 weeks old) were randomly divided into four groups, and three replicates per group (n = 20 per replicate).

A small-scale study on airborne transmission of H9N2 avian influenza virus under field conditions.

Introduction: H9N2 avian influenza viruses (AIV) can transmit in chicken flocks through direct contact and aerosols. Nevertheless, data on airborne transmission of AIV is very limited, especially under field conditions. To fill this literature gap, this study was designed to investigate airborne transmission of H9N2 AIV originating from infected chicken flocks under field conditions, with the aim to further characterize the airborne transmission of H9N2 AIV.

Avian influenza virus H9N2 seroprevalence and risk factors for infection in occupational poultry-exposed workers in Tai'an of China.

To determine risk factor for H9N2 avian influenza virus (AIV) infection, a serological surveillance among both occupational poultry-exposed (OPE) workers and general humans was carried out using both haemagglutination inhibition (HI) and microneutralization (MN) assays in Tai'an, China, between 2011 and 2013. At baseline, the positive rate of anti-H9 antibody (HI and MN titers ≥40) among OPE workers (51/600, 8.5%) was significantly higher than that among the general population (11/600, 1.

Phylogenetic Analysis of Hemagglutinin Genes of H9N2 Avian Influenza Viruses Isolated from Chickens in Shandong, China, between 1998 and 2013.

Since H9N2 avian influenza virus (AIV) was first isolated in Guangdong province of China, the virus has been circulating in chicken flocks in mainland China. However, a systematic phylogenetic analysis of H9N2 AIV from chickens in Shandong of China has not been conducted. Based on hemagglutinin (HA) gene sequences of H9N2 AIVs isolated from chickens in Shandong of China between 1998 and 2013, genetic evolution of 35 HA gene sequences was systematically analyzed in this study.
