Background: Acephalic spermatozoa syndrome is a rare but severe type of teratozoospermia. The familial trait of acephalic spermatozoa syndrome suggests that genetic factors play an important role. However, known mutations account for only some acephalic spermatozoa syndrome patients, and more studies are needed to elucidate its pathogenesis.

Mediating Role of Financial Toxicity in the Relationships Between Health-Related Quality of Life and Its Risk Factors in Chinese Patients With Cancer.

Background: Factors influencing health-related quality of life (HRQoL) and financial toxicity (FT) have been found to overlap, and the robust correlation between HRQoL and FT raises the possibility that FT mediates the relationships between the shared risk factors and HRQoL. However, empirical evidence supporting this hypothesis is limited.

Objective: This study aimed to explore whether FT mediates the relationships between HRQoL and its risk factors.

The decline in sperm parameters among obese males has attracted significant scholarly interest. The intestinal microbiota plays a crucial role in obesity, and investigating the intestinal-reproductive axis may offer a novel molecular approach to addressing the decline in male sperm parameters caused by obesity. To clarify whether probiotics, either alone or in conjunction with metformin, can enhance sperm parameters in obese male mice and assess the underlying mechanisms involved.

Study on the early diagnostic value of nanopore sequencing in alveolar lavage fluid smear-negative pulmonary tuberculosis.

The objective of this study was to investigate the early diagnostic value of nanopore sequencing in alveolar lavage smear-negative pulmonary tuberculosis (PTB). A prospective study was conducted on patients hospitalized at Zhuzhou Central Hospital from October 2021 to June 2022 and suspected to have PTB. Alveolar lavage fluid specimens were collected from these patients and simultaneously subjected to centrifugal bacterial collection smear method in a sandwich cup, bifidobacteria solid culture (referred to as culture), Mycobacterium tuberculosis-DNA (TB-DNA), and nanopore sequencing for detection of Mycobacterium tuberculosis.

PGAM5 promotes RIPK1-PANoptosome activity by phosphorylating and activating RIPK1 to mediate PANoptosis after subarachnoid hemorrhage in rats.

Neuronal death plays a crucial role in early brain injury after subarachnoid hemorrhage (SAH). PANoptosis is a programmed form of cell death regulated by the PANoptosome, which possesses key characteristics of pyroptosis, apoptosis and necroptosis. Phosphoglycerate mutase family member 5 (PGAM5) has specific phosphatase activity that phosphorylates or dephosphorylates serine and threonine residues on bound proteins such as receptor-interacting protein kinase 1 (RIPK1), which are involved in programmed cell death.

Dynamic PAH-Related Changes: A Dataset of tRNA-Derived Small RNA Transcriptome Across Multiple Organs.

Pulmonary arterial hypertension (PAH) is a severe cardiopulmonary disease characterized by elevated pulmonary artery pressure and cardiac dysfunction, often leading to heart failure and even death. Despite the complexity of its mechanisms, the molecular basis of PAH remains unclear. tRNA-derived small RNAs (tsRNAs) are noncoding RNAs that play regulatory roles in various diseases.

Distinct effects of physical and functional ablation of brown adipose tissue on T3-dependent pathological cardiac remodeling.

Heart failure tends to deteriorate in colder climates, heightening the risk of major adverse cardiovascular events. Brown adipose tissue (BAT) serves as both a thermogenic organ and an atypical site for triiodothyronine (T3) synthesis in response to cold. This study investigates the potential role of BAT in contributing to abdominal aortic constriction (AAC)-induced pathological cardiac remodeling during cold exposure.

Corticosteroids for hospitalized patients with severe/critical COVID-19: a retrospective study in Chongqing, China.

Corticosteroids have always been recommended for severe cases of COVID-19. However, the efficacy of treatment with corticosteroids for COVID-19 during the SARS-CoV-2 omicron outbreak in China has not been reported. Clinical data from 406 patients hospitalized for severe/critical COVID-19 from December 2022 to January 2023 at six hospitals in Chongqing were retrospectively analyzed.

Systematic analysis based on bioinformatics and experimental validation identifies as a novel therapeutic target of quercetin for sepsis.

Purpose: This study investigated the molecular mechanism of quercetin in the treatment of sepsis using network pharmacological prediction and experimentation.

Methods: Hub genes were identified by intersecting the differentially expressed genes (DEGs) of the GSE131761 and GSE9960 databases with genes from the hub modules of Weighted Gene Co-Expression Network Analysis (WGCNA), targets of quercetin, and ferroptosis. Subsequently, in order to determine the functional characteristics and molecular link of hub gene obtained above, we redetermined the hub-DEGs in GSE131761 according to high or low hub gene expression.
