In vitro oocyte maturation (IVM) technology is important for assisted animal and human reproduction. However, the maturation rates and developmental potential of in vitro-matured oocytes are usually lower than those of in vivo-matured oocytes. Oxidative stress is a main factor that causes the lower maturation rates and quality of in vitro-matured oocytes. The purpose of this study was to investigate the effects of treatment with SkQ1, a mitochondria-targeted antioxidant, on mouse IVM and subsequent embryonic development. The results demonstrated that the supplementation of SkQ1 during IVM improves the maturation rates of mouse oocytes and the subsequent developmental competence of in vitro-fertilized embryos. The addition of SkQ1 to the IVM medium also decreased oxidative stress and apoptosis, and increased mitochondrial membrane potential in matured mouse oocytes. This study provides a new method through which to enhance the maturation rates and the quality of in vitro-matured mouse oocytes, thus promoting the application and development of assisted animal and human reproductive technology.

In recent years, there has been a significant increase in minors with gender dysphoria (GD) seeking transition treatments, including puberty blockers and cross-sex hormones. The developing child's brain exhibits structural and functional differences in children with GD compared to cisgender children, particularly in areas where sex differences exist. Brain development during childhood and adolescence is strongly influenced by sex hormones.

Despite therapeutic advances, multiple myeloma (MM) remains incurable, especially in relapsed/refractory (R/R) cases. B-cell maturation antigen (BCMA) is a key target for novel immunotherapies, including chimeric antigen receptor T-cell (CAR-T) therapies and bispecific T-cell engagers (BiTEs), which vary in efficacy, toxicity, and accessibility. To compare the efficacy and safety of BCMA-directed CAR-T therapies and BiTEs in R/R MM through a systematic review and meta-analysis.

Zona pellucida glycoprotein-1 (ZP1) is essential for maintaining oocyte structural integrity and facilitating fertilization. Mutations in are strongly associated with primary infertility disorders such as fertilization failure and empty follicle syndrome; however, the absence of accurate experimental models has hindered mechanistic understanding and obscured the etiological basis of -related infertility. In this study, CRISPR/Cas9-mediated genome editing was employed to generate two -edited cynomolgus macaques ( ), designated #ZP1-1 (male) and #ZP1-2 (female).

Background: Cervical vertebral maturation (CVM) is a skeletal maturity method that can be assessed routinely on whole spine radiographs to minimize radiation exposure. Originally used in orthodontics, its role in staging adolescent growth spurt and curve progression in adolescent idiopathic scoliosis (AIS) remains unclear. The aim of this study was to investigate growth rates across CVM stages, its cutoff for indicating peak growth (PG) versus growth cessation (GC), and its relationship with coronal curve progression.

The short lifespan of polymorphonuclear neutrophils (PMNs) in vitro poses challenges, as their limited viability restricts functional assays and experimental manipulations. The HL-60 cell line serves as a valuable model for neutrophil-like differentiation, yet the functional relevance of ATRA- and DMSO-induced differentiation remains incompletely understood. In the present study, we aimed to characterize the differentiation potential of all-trans retinoic acid (ATRA) and dimethyl sulfoxide (DMSO) on HL-60 cells and compare their functionality with primary PMNs.
