Hair growth and pigmentation in mice involve specific stages crucial for research.

This study concluded that current cross-sex hormone treatments for trans men and trans women are effective with a low risk of side effects in the short term, though they did observe specific clinical changes.

This study suggests that oral budesonide may not effectively maintain remission in Crohn's disease beyond three months, with minor benefits that are outweighed by increased rates of treatment-related adverse events.

This review covers the history and development of CRISPR-Cas9 technology, highlighting its groundbreaking applications and the ethical concerns surrounding its use in human germline editing.

This review discusses the role of the endocannabinoid system in skin health and disease, highlighting its potential for future research and applications, but reports no new experimental results.

This source reports that while creatine supplementation is popular for improving muscle mass and performance, questions about its efficacy and safety persist. An expert team is reviewing literature to address concerns like water retention, renal effects, and its benefits across different populations and uses.

This article provides an overview of crystallization processes, challenges, and applications, discussing various techniques and examples, but it reports no new experimental findings.

In this study, the researchers established a dose–response relationship between the hair follicle dose during cranial irradiation and the development of permanent alopecia, with other factors showing limited correlation.

This study concluded that the receptor-like kinase ERULUS, regulated by auxin, is crucial for modulating cell wall composition and pectin dynamics during root hair growth in Arabidopsis.

This study found that CRISPR/Cas9-mediated disruption of the FGF5 gene in goats increased hair follicle numbers and fiber length, suggesting more cashmere production could be achieved.

This study found that a mutation in the BMP12/GDF7 gene is associated with the Naked neck trait in chickens, reducing neck feathering due to altered signaling pathways.

Finasteride affects male rat genitalia development, causing abnormalities during specific pregnancy days.

Diazoxide, minoxidil sulphate, and cromakalim relax rat blood vessels by opening K+ channels, with some differences in their actions.

This review examines PAK4 signaling pathways in prostate cancer, Parkinson's disease, and melanogenesis, focusing on the potential role of the PAK4-CREB axis, without reporting new clinical results.

This review discusses the properties and therapeutic potentials of beta-sitosterol, highlighting a need for more detailed studies on its mechanisms and long-term effects in humans; it reports no new results.

This review assesses the benefits and limitations of various supramolecular hydrogels, including polymeric and peptide-based types, for wound healing, but reports no new clinical results.
