The plateau environment is characterized by low oxygen, low air pressure, low temperature, and strong ultraviolet rays, etc. Chronic obstructive pulmonary disease (COPD) is a preventable and treatable chronic lung disease. High altitude environment increases COPD prevalence, clinical manifestation and mortality.

We aim to describe the population PK of atorvastatin (ATV) to identify patient characteristics that are predictive of variability in the PK parameters of the ATV and investigate the effects of high-altitude hypoxia on the blood concentration of ATV in patients with hyperlipidemia. A total of 160 plasma concentrations were collected from 40 patients with hyperlipidemia in plateau areas and 40 in plain areas.

Objectives: To study the inhibitory effects of 1,3-diaminopropane on the biofilm formation of and the underlying mechanisms.
Methods: The experiment was divided into an experimental group and a control group. Crystal violet staining was used to examine the inhibitory effects of 1,3-diaminopropane on the biofilm formation of , and the biofilm formation was compared between the 2 groups.
Widespread antibiotic resistance has been reported in enterococcal pathogens that cause life-threatening infections. Enterococci species rapidly acquire resistance and the pace of new antibiotic development is slow. Drug repurposing is a promising approach in solving this problem.

The combination of high-throughput screening and drug repurposing is an effective way to develop new therapeutic uses of drugs. In this study, we screened a drug library consisting of 1,573 drugs already approved by the Food and Drug Administration and 903 drugs from the natural product library, to identify antimicrobials against .

However, there are still no effective antibiofilm drugs in clinical settings. Here, by drug repurposing, we investigated the antibacterial activity of penfluridol (PF), an oral long-acting antipsychotic approved by the FDA, against E.

Compared with traditional development approaches, drug repurposing provides a faster and more effective approach to find new antimicrobial agents. In this study, we found that antispasmodic agent otilonium bromide had strong antibacterial ability and bactericidal activity against , with minimal inhibitory concentrations (MICs) of 4-8 μg/ml, and bacteria could be killed completely after treatment with 2× MIC of otilonium bromide for 5 h.

The present study aims to investigate the neuroprotection and underlying mechanisms by which Salvia miltiorrhiza Bunge (Lamiaceae) extract (SME) protects against Aβ25-35-induced apoptosis in SH-SY5Y cells. 2h Pre-treatment of SH-SY5Y cells with SME (0.
