This study found that male 5α-reductase 2 knockout mice showed deficits in social dominance behaviors and reduced dopamine receptor binding in a brain region related to social ranking.

This study reviews recent advancements in understanding caspases, highlighting their roles beyond apoptosis in cancer, inflammation, and neurological disorders, and discusses the potential and challenges of targeting caspases for therapeutic purposes.

This study found that finasteride impaired object recognition memory and altered hippocampal dendritic structures in male 3xTg-AD mice, suggesting potential sex differences in Alzheimer's disease pathology.

This study found that exogenous glutamic acid can promote hair growth and keratinocyte proliferation, suggesting a novel signalling pathway in the skin.

This study found that carvone, a plant-derived compound, decreases melanin content and inhibits melanoma cell proliferation through the cAMP pathway, suggesting potential benefits for treating melanomas and other hyperpigmentation disorders.

This study found that estazolam improved PTSD-like behavior deficits in an animal model, which was linked to increased allopregnanolone levels in specific brain regions.

This review analyzes how androgens impact sexual desire and reproductive behaviors, emphasizing molecular interactions, but provides no new clinical results.

This review discusses the nocebo effect in dermatology, highlighting its mechanisms, implications, and strategies to manage it, but does not provide new clinical research findings.

This study observed that early treatment with azithromycin and either nitazoxanide, ivermectin, or hydroxychloroquine in COVID-19 patients may reduce viral shedding, symptom duration, and respiratory complications compared to untreated patients.

In this study, researchers used computer-generated models to demonstrate that subtle changes in hair diameter, density, and style significantly affect perceptions of age, health, and attractiveness.

In this study, oral collagen peptides increased certain gene expressions related to epidermis development and the hair cycle in hairless mice skin, suggesting potential links to hair health.

In this review, the authors summarized the neuroprotective role of water- and fat-soluble vitamins in neurodegenerative diseases, highlighting their potential preventive and therapeutic effects through antioxidant and anti-inflammatory properties while acknowledging some studies question their preventive influence.

This study suggests that inhibitors of steroidogenic enzymes may have therapeutic potential for certain behavioral disorders linked to dopaminergic hyperfunction, despite concerns about their endocrine impacts.

This review discusses the effects and selection criteria of different progestogens in various treatments but reports no direct clinical comparisons of their metabolic effects.

This study found that polymeric micelle nanocarriers delivered pharmacologically relevant amounts of spironolactone to the epidermis and upper dermis, with higher delivery to pilosebaceous units, suggesting potential for treating glucocorticoid-induced impaired wound healing and pilosebaceous androgen-related skin diseases.

In this study, researchers identified genetic variants in the PCCA and PRLR genes that are significantly associated with hair coat length in Brangus heifers, potentially contributing to more thermotolerant cattle.

This article discusses how challenges in drug development and success rates are driving a shift in the pharmaceutical industry towards engineering targeted drug delivery systems, with nanomaterials offering potential solutions for selective therapeutic delivery.

This study found that taxol induces apoptosis in dermal papilla cells, affecting protein expression related to biological processes and potentially contributing to taxol-induced alopecia.

In this research, LEF1 was identified as a crucial transcription factor for submucosal gland development in mouse and ferret tracheas, though it requires other factors to induce gland formation.

This review examines the causes, assessment, and treatment options for hirsutism but presents no new clinical findings, highlighting the need for further research on managing this condition.

In this review, researchers discussed recent insights into caspases, enzymes initially associated with cell death and inflammation, revealing their broader roles in cell proliferation, migration, and differentiation, and highlighting the importance of caspase knock-out mice for understanding their implications in diseases.

This study found that women, younger individuals, and those with a low body mass index were more likely to develop long COVID symptoms, and even mild COVID-19 cases often experienced long-term residual symptoms.

In this study, UCMSC exosomes showed protective effects against cisplatin-induced hearing loss in mice by improving hearing and promoting cochlear tissue repair.

This laboratory study found that nonanal, a plant scent compound, may stimulate growth factors and cell proliferation in human hair follicle dermal papilla cells, suggesting a cAMP-mediated mechanism.

This study reported that while general patient characteristics and adverse event incidence for eribulin were comparable between a healthcare claims database and post-marketing surveillance, significant differences in some side effects such as neutropenia were observed.

This review examines regulatory mechanisms of quiescent stem cells in tissue homeostasis, drawing on observations from the intestine and other self-renewing tissues, without presenting new data.

This study found that Celsr1, not Celsr2, is the primary protein involved in establishing planar cell polarity and hair follicle polarization in the epidermis of mice.

This study demonstrated that allopregnanolone administration caused significant scratching in atopic dermatitis mice, and ethanol-induced scratching may be linked to increased brain allopregnanolone levels.
