High expression of SIGLEC7 may promote M2-type macrophage polarization leading to adverse prognosis in glioma patients.

Introduction: Gliomas are the most common primary intracranial tumors, known for their high invasiveness and destructiveness. Sialic acid-binding immunoglobulin-like lectin 7 (SIGLEC7) is present in various immune cells, especially macrophages, and significantly affects immune homeostasis and cancer cell response. However, research on the role and prognostic impact of SIGLEC7 in glioma patients is currently limited.

Identification of crosstalk genes and immune characteristics between Alzheimer's disease and atherosclerosis.

Background: Advancements in modern medicine have extended human lifespan, but they have also led to an increase in age-related diseases such as Alzheimer's disease (AD) and atherosclerosis (AS). Growing research evidence indicates a close connection between these two conditions.

Methods: We downloaded four gene expression datasets related to AD and AS from the Gene Expression Omnibus (GEO) database (GSE33000, GSE100927, GSE44770, and GSE43292) and performed differential gene expression (DEGs) analysis using the R package "limma".

Identification of an exosomal miRNA-mRNA regulatory network contributing to methotrexate efficacy.

Objective: Methotrexate (MTX) is an economic and effective medicine treatment for psoriasis. Extracellular vesicle (EV) miRNA biomarkers related to its efficiency have been identified in various diseases. Whether certain miRNA profiles are associated with psoriasis treatment is unknown.

Various detailed characteristics of a new enhanced neurotrophic factor secreting rat derived bone marrow mesenchymal stem cells and its preliminary application in rat models of ischemic stroke.

Because MSC-NTF has a higher ability to secrete neurotrophic factors, it may have a greater potential than ordinary MSC in clinical applications. At present, research on MSC-NTF mainly focuses on clinical aspects, but its basic research is relatively few. In particular, the research on the comprehensive and detailed characteristics of MSC-NTF is missing.

Effects of phillyrin and forsythoside A on rat cytochrome P450 activities in vivo and in vitro.

1. Phillyrin and forsythoside A are two important active ingredients in Forsythia suspensa. However, the effects of phillyrin and forsythoside A on the activities of cytochrome P450 (CYP450) remain unclear.

Soyasaponin Ab inhibits lipopolysaccharide-induced acute lung injury in mice.

Soyasaponin Ab (SA) has been reported to have anti-inflammatory effect. However, the effects of SA on lipopolysaccharide (LPS)-induced acute lung injury (ALI) have not been reported. The aim of this study was to investigate the anti-inflammatory effects of SA on LPS-induced ALI and clarify the possible mechanism.

Effects of notoginsenoside R1 on CYP1A2, CYP2C11, CYP2D1, and CYP3A1/2 activities in rats by cocktail probe drugs.

Context: Notoginsenoside R1 (NGR1) is the main component with cardiovascular activity in Panax notoginseng (Burk.) F. H.

Relationship between matrix metalloproteinase-2 activity and cystatin C levels in patients with hepatic disease.

Objectives: A direct relationship between cystatin C levels and the severity of hepatic disease has been revealed in our previous study. This study was aimed to consider whether a correlation exists between matrix metalloproteinases (MMPs), which have been proven to be involved in liver cirrhosis, and cystatin C to reflect the severity of hepatic disease.

Design And Methods: A total of 154 consecutive patients with various liver diseases were recruited to determine their serum levels of cystatin C, MMP-2 and-9, together with other hepatic parameters.
