This study found that platelet-rich plasma significantly increased hair count, density, and the percentage of anagen hairs in patients with androgenetic alopecia, but these improvements did not correlate with platelet or growth factor levels.

This study found that cyclosporin A treatment enhances hair growth in mice by inhibiting calcineurin-NFAT1 activity, which alters keratinocyte differentiation and apoptosis-related gene expression in hair follicles.

In this study, researchers observed that hyperandrogenic PCOS patients exhibited distinct miRNA and TGFβ signaling gene expression patterns in granulosa cells, suggesting these factors may play a role in PCOS pathogenesis.

This study suggests that cigarette smoking is a significant risk factor for hidradenitis suppurativa in Polish patients, but other potential contributors like obesity and diabetes showed no strong associations.

This study observed that hair loss in captive rhesus macaques varies with season, sex, and housing conditions, and is significantly correlated with HPA axis activity as indicated by faecal cortisol metabolites.

This study concluded that an endogenous circannual rhythm of prolactin secretion in mouflon influences their seasonal hair growth and moulting cycle, which varies under different photoperiodic and melatonin treatments.

This study found that the antiandrogen drug enzalutamide reduced TMPRSS2 levels and significantly decreased SARS-CoV-2 entry and infection in lung cells, supporting further clinical trials for COVID-19 treatment.

This review discusses the need for more research on how the chronobiological control systems regulate hair follicle cycling and reports no new results.

This study reports the creation of rat liver stem cell lines that can differentiate into hepatocytes and suggests they might be useful for pharmacological and regenerative medicine applications.

This study found that both maternal and fetal hair mercury levels were significantly higher in women who had dental amalgam restorations placed before or during pregnancy, compared to those without such restorations.

This study found that polyamines enhance genome integrity by facilitating homologous recombination-mediated DNA repair, suggesting a novel role for polyamines beyond promoting cell growth and proliferation.

This study found no protective effect of topical calcipotriol on hair loss in chemotherapy patients, and the authors propose the term "atrophic telogen effluvium" for this type of hair loss.

In this study, the authors concluded that COVID-19 may not cause direct long-term harm to testicular function, but temporary indirect effects could occur, suggesting a possible delay in pursuing parenthood post-recovery.

In this study, higher expression levels of aromatase and steroidogenic acute regulatory protein were correlated with increased estrogen synthesis and fewer hair follicles in human skin, suggesting a link to elastic fiber formation and hair growth.

This study found that plasmacytoid dendritic cells are central to the pathogenesis of alopecia areata, suggesting they may help differentiate it from trichotillomania and androgenetic alopecia.

Among obese women potentially eligible for combined oral contraceptives, this study observed a higher frequency of non-alcoholic fatty liver disease in those with polycystic ovary syndrome.

This study validated the VQ-Dermato, the first dermatology-specific quality of life instrument in French, and found it to be reliable, acceptable for routine use, and more responsive than the SF36.

Alopecia areata seriously lowers quality of life, especially affecting self-image, mental health, and social life.

This study revealed that differential gene and protein expression in the "Yufen I" H line chicken breed is crucial for Columbian plumage coloration, particularly in the melanogenesis pathway.

In this study, minoxidil was found to have low toxicity in various animals, with specific heart lesions observed only in dogs at certain doses.

This study identified diltiazem, a calcium channel blocker for hypertension, as a promising repurposed treatment for influenza, enhancing antiviral efficacy when combined with oseltamivir.

In this study, higher scores of HOMA-IR and FIRI suggested that male patients with early-onset androgenetic alopecia may have insulin resistance, although no significant differences in metabolic syndrome were found compared to controls.

This study observed that nuclear β-catenin expression in non-small-cell lung carcinomas correlates with increased proliferation and loss of key cell-cycle checkpoints, suggesting an oncogenic advantage.

This study suggests that daughters of women with PCOS may have altered androgen metabolism in early childhood, with increased 5α-reductase activity potentially contributing to PCOS development.

This study reports that among men, skin surface hydration and pH change with age, but transepidermal water loss and sebum production show less variation.

In this study, researchers observed vitamin D insufficiency in many patients with Alopecia Areata, suggesting its potential role in managing this autoimmune condition.

In this study, treatment with insulin sensitizers significantly increased adipose tissue GLUT4 mRNA expression and improved insulin resistance, menstrual patterns, and androgen profiles in PCOS patients, with rosiglitazone being more effective than metformin.

This study found that combining platelet-rich plasma with adipose-derived mesenchymal stem cells significantly improved diabetic wound healing in rats by enhancing angiogenesis and modulating the Notch signaling pathway.

Testosterone replacement therapy can prevent men from fathering children and should not be used by those wanting to stay fertile.

This review suggests that skin may largely protect itself from CYP-generated reactive metabolites due to higher conjugating enzyme activities, while highlighting limitations in modeling human skin metabolism experimentally.
