This review discusses the essential roles and complex regulation of PP2A in various physiological processes and reports no clinical results; the authors highlight the need for further mouse model research to explore PP2A's therapeutic potential.

Scalp cooling significantly reduces hair loss in chemotherapy patients.

This study suggests that TGF-β 2 plays a critical role in hair follicle morphogenesis and may enhance the effectiveness of future cell therapies for hair regrowth using expanded dermal papilla cells.

This review suggests that decreased serum 25-hydroxyvitamin D levels may play a role in different types of non-scarring alopecia, but further studies are needed to explore vitamin D supplementation as a therapeutic option.

This research suggests that the vitamin D receptor may regulate hair follicle cycling and provide genoprotection against skin carcinogenesis through a mechanism independent of 1,25-dihydroxyvitamin D3, based on evidence from mouse models.

This study reports on the biochemical characteristics of S100A3 protein in human hair cuticle, notably finding its N-terminal methionine is acetylated and has a slightly lower isoelectric point compared to the recombinant version.

This article reviews the role of exosomes in promoting axonal regeneration and discusses recent findings on how exosome-borne molecules might influence the PTEN-mTOR pathway in injured neurons; it reports no new experimental results.

This study documented a variety of skin lesions in COVID-19 patients, indicating that skin rashes might be an early or sole symptom of the disease.

This study reported that higher weight-for-age z scores and rapid weight gain during infancy, especially from birth to 3 months, were linked to an increased likelihood of puberty onset in girls.

This study suggests that women with polycystic ovary syndrome may have an increased risk of COVID-19-related cardiac and renal complications, and that weight loss through lifestyle changes could help reduce these risks.

This study found that patients with alopecia areata had significantly lower serum vitamin D levels compared to controls, but these levels did not impact disease severity or pattern.

This study found no significant difference in the risk of poor glycemic control between men with type 2 diabetes using tamsulosin and those using finasteride.

This study observed that 25-hydroxyvitamin D3 restored rickets symptoms in genetically modified rats, suggesting its direct action through vitamin D receptor pathways.

This review reports that resveratrol could benefit the management of chronic illnesses such as diabetes and cardiovascular disease, but challenges with bioavailability and regulatory issues persist.

This review discusses the role of endolysosomes in SARS-CoV-2 infection and COVID-19 pathogenesis, and explores potential therapeutic strategies targeting these cellular structures, but reports no new clinical findings.

This study identified trichohyalin as an early differentiation marker in hair follicles, with potential structural roles related to alpha-helical formations, based on the partial characterization of its cDNA in sheep.

This review highlights that while dexamethasone may reduce mortality in severe COVID-19, no other drugs have proven effectiveness for treatment, emphasizing the need for clinical trials of existing medications.

This study found that applying BMP2 stimulated limited regeneration of the amputated P2 bone in mice, but only when applied during a specific "regeneration window" after injury.

This study found that fig leaf extract significantly downregulated inflammatory and androgenic gene expression in vitro, suggesting potential topical benefits for certain skin disorders.

In this extended follow-up of the PALOMA-2 trial, no significant differences in overall quality of life were observed between first-line treatments for metastatic breast cancer, but palbociclib plus letrozole showed some benefits regarding side-effects and hair loss.

In this study, researchers presented cases of cellular neurothekeoma in three male family members with early-onset in infancy, suggesting a potential genetic component and inheritance pattern, which deviates from the typical presentation seen mostly in women between 20–30 years.

This study found that 10,11-dibrominecrebanine (2Br-Cre) and Stephanine demonstrate significant anti-inflammatory and analgesic properties in various experimental models, with 2Br-Cre showing enhanced efficacy over Cre and both compounds potentially mediating their analgesic effects through opioid receptors.

This study found that lower testosterone levels in male COVID-19 patients were associated with greater disease severity and longer hospital stays.

mTORC2 is crucial for healthy skin barrier by regulating lipids and filaggrin.

This study found that Google users are increasingly searching for health information on dermatological issues, with particular interest in itch, hair loss, and skin rash.

Fusarium sp. strain K-23 helps Arabidopsis plants grow better in salty soil by promoting root hair growth.

Oral minoxidil significantly reduces hair shedding in women with chronic telogen effluvium.

Plant-based treatments may help reduce BPH symptoms, but more research is needed.

This study observed that improving male lower urinary tract symptoms was associated with a lower risk of death, with a 1-point improvement in symptoms leading to a 4% reduction in mortality risk.

In this study, researchers found that intestine-derived human alpha defensin 5 enhances wound healing, reduces bacterial load, and promotes hair growth in murine burn wound beds by increasing LGR stem cell migration.
