Background: Alveolar macrophages (AMs) play a predominant role in acute lung injury (ALI). However, the role of macrophage-derived exosomal miRNAs in lipopolysaccharide (LPS)-induced ALI has not been determined.
Methods: We previously reported that exosomes in the bronchoalveolar lavage fluid (BALF) of mice with ALI were derived predominantly from macrophages.
The purpose of this study was to explore the mechanism of action of Piceatannol (PIC) in attenuating oxidative damage to sperm during cryopreservation. Semen samples were collected and homogenized into six equal parts for freeze-thawing experiments. Four different concentrations of PIC were utilized as cryoprotectants during the freeze-thawing process, maintaing a semen to PIC ratio of 1:1, while sperm motility after freezing and thawing was analyzed using computer-assisted sperm analysis (CASA).

As a novel form of cell death, ferroptosis is reliant on the accumulation of iron and reactive oxygen species and is involved in the pathogenesis of various tumors, including ACC. Our study aimed to identify and characterize the prognostic ferroptosis-related lncRNA signature (FerRLSig) in ACC.

Methods: Data of ACC patients aged >60 years from 1975 to 2016 were obtained from the Surveillance, Epidemiology, and End Results dataset.
Background: C677T point mutation in methylenetetrahydrofolate reductase (MTHFR) gene have been found to be associated with ischemic stroke in general population, while the results seem inconsistent. We aim to assess the association between variant MTHFR C677T variant and increased risk of ischemic stroke and focus on the elderly population.
Methods: We searched PubMed, Embase, Cochrane Library, and Web of Science for eligible studies.
Background: Extranodal natural killer (NK) / T cell lymphoma is a subtype of non-Hodgkin's lymphoma (NHL) that usually has an aggressive clinical course. It is the predominant trigger of lymphoma-associated hemophagocytic syndrome (LAHS), which is highly lethal and with extremely poor prognosis. This study is aiming to characterize the associated clinical features and prognostic factors of the disease.

Glucagon-like peptide 2 (GLP-2), a growth factor found in the intestinal mucosal epithelium, reduces intestinal permeability and affects intestinal microbiota. The relationship between aging, GLP-2, and intestinal microbiota are still not well understood.

Downstream effectors of KRAS signal pathways are crucial to the development of PDAC. The purpose of this study was to investigate the relationship between KRAS mutation and transgelin-2.

Expression of the pyruvate kinase (PK) M2 isoform, rather than the PKM1 isoform, serves important functions in reprogramming the glucose metabolism of cancer cells. Preferential expression of PKM2 is primarily driven by alternative splicing, which is coordinated by a group of splicing factors including heterogeneous nuclear ribonucleoprotein (hnRNP)A1, hnRNPA2 and RNA binding motif containing.

Diabetes is a significant risk factor for PDAC and >50% of PDAC patients have concomitant diabetes. How diabetes influences the initiation and progression of PDAC remains elusive.

A group of Chinese men, aged ⩾ 45 years were included in the analysis. BMD was measured with dual-energy X-ray absorptiometry (DXA), SHBG and total testosterone (TT) was measured using chemiluminescent immunoassay, and free testosterone (FT) was calculated.

Accumulating evidences indicate SREBP1 is involved in tumorigenesis, yet its role in pancreatic cancer remains unclear. Here, we explored the expression characteristic and function of SREBP1 in pancreatic cancer.

A group of Chinese men, aged ≥ 60 years, recruited from the health checkup population of Zhongshan Hospital, Fudan University, were included. The OSTA index was calculated from age and weight.

This cross-sectional study was carried out among 404 Chinese men aged over 45 years. BMD was measured with dual-energy X-ray absorptiometry, and participants' blood was collected for bone-specific alkaline phosphates (BSAP), SHBG and testosterone assay.
