Data independent acquisition reveals in-depth serum proteome changes in uremic pruritus.

Uremic pruritus (UP) is a prevalent symptom in patients suffering from uremia, yet its underlying etiology and mechanisms remain incompletely elucidated. Given the significant incidence of UP, identifying specific alterations in proteins present in the blood of UP patients could offer insights into the potential biological pathways associated with UP and facilitate the exploration of biomarkers. In this study, we employed LC-MS/MS-based data-independent acquisition (DIA) mode to analyze serum samples obtained from 54 UP patients categorized as DKD-UP, HN-UP, and GN-UP (n = 18 for each subgroup), along with 18 uremic patients without pruritus (Negative) and 18 CKD patients without pruritus (CKD).

Expression of Rad51 and the histo-morphological evaluation of testis of the sterile male cattle-yak.

Meiotic recombination is key to the repair of DNA double-strand break damage, provide a link between homologs for proper chromosome segregation as well as ensure genetic diversity in organisms. Defects in recombination often lead to sterility. The ubiquitously expressed Rad51 and the meiosis-specific DMC1 are two closely related recombinases that catalyze the key strand invasion and exchange step of meiotic recombination.

Clinical features of and risk factors for major depression with history of postpartum episodes in Han Chinese women: A retrospective study.

Background: We sought to investigate the clinical features of and risk factors for recurrent major depression (MD) with history of postpartum episodes (PPD) in Han Chinese women and the differences between first-onset postpartum MD (MD that has its first lifetime depressive episode in the postpartum period) and first-onset non-postpartum MD (MD with history of PPD and has its first lifetime depressive episode in a period other than postpartum).

Methods: Data were derived from the China, Oxford and Virginia Commonwealth University Experimental Research on Genetic Epidemiology (CONVERGE) study (N=6017 cases) and analyzed in two steps. We first examined the clinical features of and risk factors for MD patients with (N=981) or without (N=4410) a history of PPD.

Identification of oral cancer cell-induced changes in gene expression profile of lymphatic endothelial cell.

Understading functional properties of tumor-derived lymphatic endothelial cells (TLEC) are relevant for blocking lymphatic metastasis. The changes of lymphatic endothelial cells (LEC) cocultured with oral cancer cells in a vitro model were examined. TLEC, in contrast to LEC, were more proliferative and have enhanced ability of lymphangiogenesis and anti-apoptosis.
