This study found that both finasteride and dutasteride significantly reduced L-DOPA-induced dyskinesia in a rat model of Parkinson's disease, with dutasteride showing greater effectiveness at lower doses.

This study examined the effects of finasteride on human Leydig cells and found altered methylation in dopaminergic pathways, suggesting potential epigenetic contributions to post-finasteride syndrome, warranting further investigation.

This study found that a dopamine-methacrylated hyaluronic acid hydrogel enhances the efficacy of adipose-derived stem cells in promoting skin regeneration, potentially involving the Notch signaling pathway.

This review discusses the roles of hormonal pathways in regulating male sexual function, particularly highlighting the impact of testosterone, and reports no new research findings.

Finasteride may help improve certain brain function issues linked to dopamine.

This study found that distinct neurons in the nucleus accumbens lateral shell regulate scratching behavior differently; D1R neurons promote scratching while D2R neurons help stop it, with elevated dopamine levels during chronic itch potentially enhancing persistent scratching.

This review discusses sex differences in Parkinson's disease and highlights that while men are more frequently affected, androgen-modulating treatments have not yet proven effective for PD, though 5α-reductase inhibitors show potential for further study.

This review discusses the neurobiology of sexual function and reports no new results; the authors cover multiple endocrine and neurotransmitter influences on sexual desire, arousal, and orgasm stages.

This review discusses the role of neuro(active)steroids, particularly those in the 5α reductase pathway, in modulating dopamine signaling and their impact on neuropsychiatric disorders characterized by dopamine imbalances, including addiction, schizophrenia, and Parkinson's Disease.

This study found that finasteride significantly reduced levodopa-induced dyskinesia in both male and female rats without diminishing l-DOPA's motor benefits, indicating potential for clinical trials in Parkinson's patients.

This study found that systemic administration of NDP-MSH, a melanocortin receptor agonist, provided neuroprotective effects on dopaminergic nigrostriatal neurons in a mouse model of Parkinson's disease, reducing neuroinflammation and suggesting a role for regulatory T cells in these neuroprotective effects.

This study suggests that an in ovo injection of CHIR-99021 promoted feather growth and follicle development in goose embryos by activating the Wnt signaling pathway.

This study reviewed literature on signaling pathways and concluded that these pathways are crucial pharmacological targets, influencing the mechanisms of drugs used in neurological, cardiovascular, and oncological treatments to correct signal transmission disturbances.

This study found that women with polycystic ovary syndrome had significantly higher serum lactate dehydrogenase levels and lower levels of cortisol, dopamine, zinc, and vitamin D3 compared to healthy controls.

This study found that in rodent models, the ability of D1 dopamine receptor activation to impair sensory gating is facilitated by 5α-reductase type 1, which produces allopregnanolone.

This study found that certain gene sets, including those involved in ligand-gated ion channel signaling and cell adhesion, are associated with Tourette syndrome, suggesting a potential neurobiological basis for the disorder.

In this review, the authors discuss recent advancements in underwater adhesion technologies, specifically highlighting mussel-inspired catechol-based adhesives, which offer strong underwater bonding through various interfacial interactions and the influence of dopamine-modified polymeric tissue adhesives.

This study found that progesterone pretreatment in rats potentiated the effect of ethanol on mesocortical dopamine levels, suggesting an influence of neuroactive steroids on ethanol's action.

This review discusses the role of traditional Chinese medicine and bioactive materials in chronic wound healing and reports no new clinical results.

This chapter discusses common endocrine disorders affecting the pituitary, thyroid, and adrenal glands, and their impact on human fertility, emphasizing practical evaluation and treatment algorithms.

Using too much minoxidil foam can cause a rare movement disorder with facial twitching, but symptoms go away when the correct dose is used.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

In this study on Drosophila wings, researchers identified 435 genes with significant expression changes during wing hair morphogenesis, and found new phenotypes for 9 genes through functional validation.

This review discusses post-SSRI sexual dysfunction and post-finasteride syndrome, highlighting unknowns about their true incidence and underlying causes, and reports no new clinical results.

This study suggests that prolactin has complex, gender- and location-dependent effects on human hair follicles, promoting hair growth in female frontotemporal scalp areas while inhibiting it in male occipital regions.

This study found that early life stress significantly affects hedonic sensitivity to high-palatable food by altering gonadal hormones in prenatally-stressed male and female rats, with sex-dependent changes in reward-related behaviors and neurochemistry.

This study found that activating CB1 receptor signaling in human hair follicles increased stem cell proliferation while reducing differentiated cell survival, suggesting CB1's role as a survival stimulus for epithelial stem cells.

This study presents a computational approach, CATNIP, which repurposes drugs using only their biological and chemical information, predicting new uses like adrenergic uptake inhibitors for Parkinson's and vandetanib for Type 2 Diabetes.

This systematic review and meta-analysis found 30 genetic loci associated with skin ageing phenotypes, noting shared biological pathways in aspects like pigmentation and wrinkling; researchers suggest further studies targeting the same SNP across populations could clarify these associations.

This study found that acupuncture may reduce anxiety and depression in women with polycystic ovary syndrome, potentially through hormonal and neuroendocrine modulation, but further high-quality research is needed to confirm these findings.
