Humanin alone and in Combination with GnRHa therapy attenuates ovarian dysfunction induced by prepubertal cyclophosphamide chemotherapy in female mice.

Prepubertal chemotherapy induced ovarian damage poses a significant threat to female fertility, particularly following cyclophosphamide (CP) treatment. Humanin (HNG), a small molecule polypeptide encoded by mitochondrial DNA, has a variety of effects, this study aimed to investigate the protective effects of HNG and its combination with conventional Gonadotropin Releasing Hormone Agonist (GnRHa) on ovarian function in a CP-induced damage model. The 21-day-old C57BL/6J female mice were randomly assigned to six groups: Control, CP model, HNG, HNG+CP, GnRHa+CP, and HNG+GnRHa+CP.

Evolution of interspecific interactions underlying the nonlinear relationship between active biomass and pollutant degradation capacity in bioelectrochemical systems.

This study proposes a switching operating mode that alternates between microbial fuel cell (MFC) and microbial electrolysis cell (MEC) to restore the biofilm activity and organic pollutant degradation capacity in bioelectrochemical systems (BESs) during prolonged operation. After the model switching, the toluene degradation kinetics in BESs equipped with graphite sheet (GS) and polyaniline@carbon nanotubes (PANI@CNTs) bioanodes were elevated by 2.10 and 3.

S6K1 is a Targetable Vulnerability in Tumors Exhibiting Plasticity and Therapy Resistance.

Most tumors initially respond to treatment, yet refractory clones subsequently develop owing to resistance mechanisms associated with cancer cell plasticity and heterogeneity. We used a chemical biology approach to identify protein targets in cancer cells exhibiting diverse driver mutations and representing models of tumor lineage plasticity and therapy resistance. An unbiased screen of a drug library was performed against cancer cells followed by synthesis of chemical analogs of the most effective drug.

Exploration of the feasibility of clinical application of phage treatment for multidrug-resistant -induced pulmonary infection.

() commonly induces refractory infection due to its multidrug-resistant nature. To date, there have been no reports on the application of phage treatment for infection. This study was conducted to explore the feasibility of phage application in treating refractory infection by collaborating with a 59-year-old male patient with a pulmonary infection of multidrug-resistant Our experiments included three domains: ) selection of the appropriate phage, ) verification of the efficacy and safety of the selected phage, ) confirmation of phage-bacteria interactions.
