Integrated bioinformatics and experimental validation identify lysosome and immune infiltration-related genes as therapeutic targets in late-onset major depressive disorder.

This study leverages bioinformatics to identify differential genes linked to lysosomal alterations in late-onset major depressivedisorder (LOD) patients and explores potential therapeutic drugs. We analyzed differential genes in the GSE76826 dataset usingWGCNA to identify modules associated with LOD. After intersecting with lysosomal genes, we utilized ROC and Lasso regression toassess diagnostic significance.

Glycyrrhizic Acid From Glycyrrhiza uralensis Fish: A Novel Therapeutic Candidate for Alzheimer's Disease Targeting the JNK Signaling Pathway.

Alzheimer's disease (AD) has emerged as a prevalent public health concern. This study aims to investigate the mechanism of Glycyrrhiza uralensis Fish. in AD through the utilization of network pharmacology, molecular docking, and in vitro validation techniques.

Exploring the diagnostic potential of IL1R1 in depression and its association with lipid metabolism.

Background: Depression is a complex mental disorder where oxidative stress and lipid metabolism disorders play crucial roles, yet their connection requires further exploration. This study aims to investigate the roles of oxidative stress and lipid metabolism disorders in depression using bioinformatics methods and Mendelian randomization analysis.

Methods: A differential gene expression analysis was performed on the GSE76826 dataset, followed by identification of the intersection with genes related to OS.

The association of vitamin deficiency with depression risk in late-life depression: a review.

Late-life depression (LLD), a growing public health challenge in aging societies, profoundly impacts physical and mental health by exacerbating cognitive decline, functional disability, and comorbid chronic diseases. Emerging research highlights vitamin supplementation as a promising adjunctive therapy for LLD, targeting its multifactorial pathogenesis involving mitochondrial dysfunction, neuroinflammation, and oxidative stress. Specific vitamins, including B-complex vitamins (B1, B6, B9, B12), vitamin D, and antioxidants (C, E), demonstrate therapeutic potential through mechanisms ranging from neurotransmitter regulation to mitochondrial function enhancement.

Sarcopenia in trauma patients: A systematic review and meta-analysis.

Sarcopenia is associated with poor prognosis and mortality following injury. This systematic review and meta-analysis aimed to analyze diagnostic criteria for sarcopenia, as well as to assess its prevalence and impact on health outcomes among trauma patients. We conducted a literature search on MEDLINE, EMBASE, and the Cochrane Library from inception to June 2023.

[Resveratrol attenuates cardiac function impairment in plateau hypobaric hypoxia rats].

To study the protective effects of resveratrol (RSV) on cardiac function in rats with high altitude hypobaric hypoxia and its mechanisms. Thirty-six rats were randomly divided into control group, hypobaric hypoxia group (HH) and hypobaric hypoxia + RSV group (HH+RSV) according to the random number, 12 rats in each group. Rats in the HH and HH+RSV groups were subjected to chronic long-term high altitude hypobaric hypoxia intervention for 8 weeks in a hypobaric chamber at a simulated altitude of 6 000 m for 20 h / d.

[DNA barcoding identification of Ginseng Radix et Rhizoma and Panacis Quinquefolii Radix based on trnL-trnF sequences].

To optimize indices of molecular identification for authentication of Ginseng Radix et Rhizoma and Panacis Quinquefolii Radix, four indices, including sequence similarity, specific positions, genetic distance and phylogenetic tree, were compared based on trnL-trnF sequences. Total DNA was extracted from Ginseng Radix et Rhizoma and Panacis Quinquefolii Radix, and trL-trnF sequences were amplified and sequenced. Sequence similarity was calculated by BLAST analysis.

[Effects of abscisic acid on chemical components content and color of Glycyrrhiza uralensis].

An experiment was conducted using cultivated Glycyrrhiza uralensis in age of one year to study the effects of abscisic acid (ABA) on chemical components content and color of G. uralensis. By using different concentrations of ABA spraying on leaves, the change of the chemical component content was analyzed within 45 d after ABA stimulation, and the effects on quality were studied combined with colorimetric analysis data.

[A new herbs traceability method based on DNA barcoding-origin-morphology analysis--an example from an adulterant of 'Heiguogouqi'].

The fruit of Lycium ruthenicum is a common folk medicine in China. Now it is popular for its antioxidative effect and other medical functions. The adulterants of the herb confuse consumers.
