Influence of gut flora on diabetes management after kidney transplantation.

Post-transplant diabetes mellitus (PTDM) is a common complication following renal transplantation, and its incidence has been gradually increasing in recent years, posing a significant public health challenge. Managing PTDM is complex, as studies suggest that it involves changes in the microbial flora across multiple organs. Recent research highlights the critical role of gut flora metabolism in the development of diabetes among post-renal transplant patients.

Water Microdroplets Promote Spontaneous Oxidation of Amino Acid- and Peptide-related Thiols to Disulfide Bonds.

Disulfide bonds (S-S) play a critical role in modern biochemistry, organic synthesis and prebiotic chemistry. Traditional methods for synthesizing disulfide bonds often rely on oxygen, alkali,  and metal catalysts. Herein, thiol groups involved in amino acids and peptides were spontaneously converted into symmetrical and unsymmetrical disulfide bonds within water microdroplets, without the need for catalysts or oxygen, and under room temperature.

Human induced pluripotent stem cell line XXMUFAi001-A generated from a patient harboring KCNH2 mutation (c. 2690 A>C).

Long QT syndrome type 2 (LQT2), caused by mutations in the KCNH2 gene, is an inherited ion channel disorder associated with sudden death in adolescents. In this study, we generated a patient-specific induced pluripotent stem cell (iPSC) line XXMUFAi001-A using non-integrative Sendai reprogramming technology from an individual carrying a heterozygous point mutation (c.2690 A>C) in KCNH2.

Relationship between circulating miRNA-222-3p and miRNA-136-5p and the efficacy of docetaxel chemotherapy in metastatic castration-resistant prostate cancer patients.

Background: Metastatic castration-resistant prostate cancer is the most dangerous stage of prostate cancer, with a high mortality rate. Docetaxel chemotherapy is one of the most effective treatment methods currently, but some patients do not respond to chemotherapy. To avoid unnecessary toxicity in non-responders, this study explores the potential of circulating microRNAs as early biomarkers of docetaxel response in patients with metastatic castration-resistant prostate cancer.

Selenium promotes neural development through the regulation of GPX4 and SEPP1 in an iPSC-derived neuronal model.

Selenium (Se) is incorporated into selenoproteins in the form of selenocysteine, which has biological functions associated with neural development. Unfortunately, the specific roles and mechanisms of selenoproteins at different stages of neuronal development are still unclear. Therefore, in this study, we successfully established a neuronal model derived from induced pluripotent stem cells (iPSC-iNeuron) and used Se nanoparticles (SeNPs@LNT) with high bioavailability to intervene at different stages of neural development in iPSC-iNeuron model.
