This study aims to investigate the effect of Zhishi Xiebai Guizhi Decoction on the phenotypic transformation of pulmonary artery smooth muscle cells(PASMCs) in rats with hypoxic pulmonary hypertension(HPH). Healthy SPF SD rats were randomly assigned to five groups: control group, hypoxia model group, hypoxia + low-dose Zhishi Xiebai Guizhi Decoction group(440 mg·kg~(-1)·d~(-1)), hypoxia + high-dose Zhishi Xiebai Guizhi Decoction group(880 mg·kg~(-1)·d~(-1)), and hypoxia + sildenafil group(30 mg·kg~(-1)·d~(-1)), with right rats in each group. Rats in the hypoxia model and hypoxia + drug groups were exposed to a hypobaric oxygen chamber with a simulated altitude of 5 000 m to induce the PH model.

To date, various strategies have been reported for the selection or design of non-volatile solid additives. However, the lack of a general design/evaluation principles for developing non-volatile solid additives often results in individual solid additives offering only one or two efficiency-boosting attributes.

Its physiological effects are similar to those of thyroid hormones, prompting numerous investigations into potential correlations and interactions between irisin and thyroid function through various in vitro and animal experiments. However, existing studies suggest that the relationship between irisin and thyroid diseases is highly complex and multifaceted.

Glial cells, particularly astrocytes, are active components of the brain and are responsible for synaptic activity through the release gliotransmitters. A reduced density of astrocytes and astrocyte dysfunction have both been identified the brains of patients with MDD.

Acetic acid is a common inhibitor present in lignocellulose hydrolysate, which inhibits the ethanol production by yeast strains. Therefore, the cellulosic ethanol industry requires yeast strains that can tolerate acetic acid stress. Here we demonstrate that overexpressing a yeast native arginase-encoding gene, , renders acetic acid tolerance.

Mucosal immunity is posed to constantly interact with commensal microbes and invading pathogens. As a fundamental cell biological pathway affecting immune response, autophagy regulates the interaction between mucosal immunity and microbes through multiple mechanisms, including direct elimination of microbes, control of inflammation, antigen presentation and lymphocyte homeostasis, and secretion of immune mediators. Some of these physiologically important functions do not involve canonical degradative autophagy but rely on certain autophagy genes and their 'autophagy gene-specific functions.

MNV causes chronic infection by directly infecting intestinal tuft cells, rare chemosensory epithelial cells. Although MNV induces functional MNV-specific CD8 T cells, these lymphocytes fail to clear infection.

Here we report that loss of autophagy in lung macrophages and dendritic cells results in acute susceptibility of mice to high-dose Mtb infection, a model mimicking active tuberculosis. Rather than observing a role for autophagy in controlling Mtb replication in macrophages, we find that autophagy suppresses macrophage responses to Mtb that otherwise result in accumulation of myeloid-derived suppressor cells and subsequent defects in T cell responses.

However, the researches of KDF in animal production mostly focused on apparent indexes such as growth performance and the mechanisms of KDF on intestinal health have not been reported. Thus, porcine small intestinal epithelial cells (IPEC-J2) infected with Enterohemorrhagic Escherichia coli (EHEC) was used to investigate the role of KDF on alleviating intestinal inflammation in this study.

Metabolomics is an important component of system physiology that concerns systematic studies of the metabolite spectrum in one or more biological systems, such as cells, tissues, organs, body fluids, and organisms. Unfortunately, conventional GC-MS detectors also feature low scan rates, high ion loss rates, and a narrow concentration detection range, which limit their applications in the field of metabolomics.
