This review discusses the host genetic factors influencing COVID-19 susceptibility and pathogenesis, highlighting genetic variations that affect viral entry and immune responses, but reports no new experimental results.

This review highlights significant health risks associated with anabolic-androgenic steroid use in women and reports no new research results, emphasizing the need for further understanding of their effects on female physiology.

This study found that the MIR34A rs2666433 (A/G) variant is linked to increased risk and severity of alopecia areata, and high circulatory miR-34a levels may play a role in the disease's pathogenesis.

In this study, nifedipine provided rapid symptomatic relief in most patients with severe recalcitrant perniosis, but some experienced side effects that limited dosage and two patients were lost to follow-up.

In this study, Allium hookeri extract increased viability and size of dermal papilla cell spheroids and reduced oxidative stress effects, potentially promoting hair growth by regulating specific protein signaling pathways in human cells.

In this study, researchers found that male and female APCHi mice exposed to ionizing radiation showed near-normal lipid and metabolite levels, suggesting activated protein C may offer some protective effects against radiation-induced damage affecting organ systems.

In this study, women with PCOS exhibited a significantly elevated low-grade inflammatory profile through salivary cytokines, with IL-1β and TNF-α demonstrating strong potential as non-invasive diagnostic markers, alongside traditional androgen measures like FAI.

This review suggests that low-dose oral minoxidil may enhance hair density in certain nonandrogenetic alopecias, but highlights the need for controlled trials due to mixed and limited evidence.

In this study, nearly two-thirds of Saudi adults reported experiencing hair loss following COVID-19 infection or vaccination, with female sex and nutritional deficiencies identified as significant correlates for this condition.

In this study, genetic factors associated with hirsutism were identified, suggesting that both androgen-dependent and independent mechanisms may contribute to excessive hair growth in women.

This study observed that in androgenetic alopecia patients, the expression of CD34+ progenitor cells significantly decreased in frontal scalp biopsies, while Sox9 expression remained consistent, suggesting that altered conversion of hair follicle stem cells to progenitors may significantly contribute to AGA development.

This study found that Ca²⁺ signaling and peptidylarginine deiminase enzymes play a crucial role in activating neural stem cells in response to injury in zebrafish, suggesting potential therapeutic targets for CNS injuries and cancer.

In this study, researchers used a 3D printing technique to spatially pattern human dermal papilla cell spheroids in a collagen matrix, enhancing skin and hair regeneration in a mouse model, with notable upregulation of key genes for hair follicle formation compared to traditional cell cultures.

This study found that hair steroid analysis effectively detected increased hormone levels from both a single testosterone dose and laboratory-induced stress, revealing individual context factors like relationship status also impact hair hormone concentrations.

This study in Saudi Arabia found that 55.9% of participants reported premature graying of hair before age 30, with risk factors including genetic, health, and lifestyle aspects such as smoking, anxiety, nutrient deficiencies, and family history.

In this study, researchers described protocols using C3H/HeJ mice to reliably induce alopecia areata through full-thickness skin grafts or adoptive transfer of cultured lymphoid cells, offering valuable models for studying the disease and testing new drug therapies.

This study found that undiluted mint leaf extract effectively inhibited multidrug-resistant Staphylococcus aureus and killed Culex pipiens larvae, suggesting its potential as a biocontrol strategy around hospitals.

This study found that a novel ECM patch combining human fibroblast-derived matrix and PVA hydrogel, seeded with human mesenchymal stem cells, significantly improved wound healing and tissue regeneration in a mouse model.

This study found that in Korea, nonbald individuals perceive balding men as older and less attractive, with women more likely than nonbald men to view them as less attractive.

This study found that cubosomal suspensions significantly enhanced the hair growth-promoting effects of Thuja orientalis, Polygonum multiflorum Thunberg, and Espinosilla extracts in a mouse model, making them as effective as Minoxidil.

This study investigated the role of NLRP3 inflammasomes in alopecia areata and found that outer root sheath cells may contribute to inflammation by increasing IL-1β and HMGB1 secretion when stimulated with double-stranded RNA.

In this study, corn silk extract treatment improved symptoms of testosterone-induced BPH by reducing specific mRNA expression and decreasing levels of 5α-R2, DHT, and PSA.

In this study, thread-embedding therapy enhanced hair regrowth in C57BL/6 mice by regulating growth factors associated with hair follicle anagen development and promoting cellular proliferation in hair follicles.

This study reported that genetic changes in trichilemmal carcinoma resemble those in other skin cancers, with TP53 mutations associated with aggressive clinical outcomes.

This study found that Th17 lymphocytes may play a more crucial role than cytotoxic T cells in the development of alopecia areata due to their infiltration around the hair bulb/bulge, which exacerbates hair loss as histopathological grade worsens.

This study found that a gelatin microparticle-containing self-microemulsifying formulation combined with Soluplus improved the oral absorption of dutasteride.

This study found no significant associations between the polymorphisms of SRD5A1 and SRD5A2 genes and androgenetic alopecia, clinical types of baldness, or response to finasteride in Koreans.

In this animal study, researchers found that finasteride reduced bacterial infection and inflammation in chronic bacterial prostatitis, with the greatest effect when combined with ciprofloxacin.

In this study, hydrolysates of lactic acid bacteria were found to enhance hair growth in C57BL/6 male mice more effectively than 5% minoxidil.

This article outlines the first prospective cohort study examining whether bariatric surgery can induce satisfactory weight loss in obese Koreans, with no new results reported yet.
