The emergence of antibiotic-resistant , especially methicillin-resistant (MRSA), poses a great challenge for animal and public health. This study aimed to isolate a broad-spectrum and high-efficiency MRSA phage and explore the phage-antibiotic synergistic effect on MRSA. Phage STPX-6 belongs to , .

It is urgent to find alternative antibiotics. In order to explore a new method for controlling methicillin-resistant Staphylococcus aureus (S.

Herein, we explored the protective effect and potential molecular mechanism of CoQ10 on lipopolysaccharide (LPS)-induced acute lung injury (ALI). We found that medium (10 mg/kg) and high (50 mg/kg) doses of CoQ10 ameliorated LPS (50 µg/µL)-induced ALI to varying degrees, as demonstrated by reduced lung coefficient, lower wet/dry weight lung tissue ratio, decreased bronchoalveolar lavage fluid protein concentration, less anatomical and histopathological damage to the lung, and increased expression of proteins related to lung epithelial barrier structure.

The neuroprotective effect of miR-137 has been reported before, however, the effect of on isoflurane triggered neuronal apoptosis, and whether miR-137 is involved in the neuroprotection of DEX remain unclear. To investigate these doubts, we established an isoflurane exposure model in postnatal day 7 (P7) Sprague‒Dawley rats and the PC12 cells, containing a control group (CON), isoflurane group (ISO), DEX group (DEX) and DEX pretreatment group (DEX + ISO).

Introduction: To understand the prevalence of avian methicillin-resistant (MRSA) and the current status of drug resistance in Qingdao, a comprehensive molecular epidemiological investigation and analysis of evolutionary relationships of MRSA isolates from broiler and layer chickens and waterfowl was conducted.
Material And Methods: One hundred and two avian MRSA strains were identified by multi-locus sequence typing, staphylococcal protein A () and staphylococcal cassette chromosome (SCCmec) typing, and whole-genome sequencing.
Results: The sequence type (ST) 9-t899-SCC IVb type represented the highest proportion of avian-derived MRSA strains (71.
Aflatoxins B1 (AFB1), a type I carcinogen widely present in the environment, not only poses a danger to animal husbandry, but also poses a potential threat to human reproductive health, but its mechanism is still unclear. To address this question, multi-omics were performed on porcine Sertoli cells and mice testis. The data suggest that AFB1 induced testicular damage manifested as decreased expression of GJA1, ZO1 and OCCLUDIN in mice (p < 0.

In this study, a natural C-terminally truncated variant of mouse Bestrophin 3 (Best3V2) expression in myoblasts and muscles is demonstrated. Unlike full-length Best3, Best3V2 targets the two important intracellular Ca stores: the lysosome and the ER.

As an environmental endocrine disruptor, it has been shown to be harmful to the mammalian reproductive system. Previous studies indicated that DEHP inhibited the development of mouse ovarian follicles.

However, n-3 PUFAs cannot be endogenously synthesized by mammals because they lack the dehydrogenase that converts n-6 to n-3 PUFA.

Currently, n-3 polyunsaturated fatty acids (n-3 PUFAs) have attracted great attention because of their biological significance to organisms. In addition, PUFAs show an obvious impact on prevention and treatment of various diseases. Because n-3 PUFAs cannot be endogenously synthesized by mammals, mammals have to rely on a dietary supplement for sufficient supply.
