This article discusses various aspects of hair and scalp health, ancient philosophical perspectives on hair, and causes of hair disorders in children, without reporting new clinical results.

This article discusses differences in hair loss among monozygotic female twins despite identical genetics and reports no new clinical findings.

This study found that dietary vitamin E influenced gene expression in rat livers, altering genes related to metabolism, coagulation, and steroid processing, and confirmed its effects on related biological endpoints.

This review found that oral JAK inhibitors, used off-label in various inflammatory skin disorders, often resulted in rapid and sustained clinical improvements with acceptable safety over several months, although the evidence is drawn from case-based reports.

This study suggests that P. orientalis leaf-derived EVs could offer anxiolytic, antidepressant, and sleep-inducing benefits by affecting neurotransmitter levels and reducing inflammation, particularly when administered intranasally.

This review highlights how natural products with antioxidant properties can modulate the Wnt signaling pathway, potentially influencing various pathological conditions such as cancer, stroke, and regenerative medicine. It also addresses controversies in the compounds' mechanisms across different models and suggests research directions for future studies.

This study found that specific TRPM5 modulators are unlikely to directly affect sebaceous glands, but safe TPPO analogues may provide moderate lipogenic and anti-inflammatory effects beneficial for dry skin conditions.

In this study, bioengineered hair germ microspheres made from HME hydrogels promoted hair follicle regeneration in vivo, suggesting a promising approach for hair loss treatment.

This study identified a primitive coarse wool characteristic in Merino sheep that enhances environmental adaptability and fine wool yield without reducing quality, suggesting that epigenetic mechanisms, particularly involving the imprinted Gtl2-miRNAs locus, regulate this advantageous trait.

In this study, researchers are constructing a comprehensive data set from 997 adult participants in Japan to develop a statistical model that explores the relationships among various health parameters, aiming to enable personalized and preventive health care interventions based on empirical data.

This review reports no new results and highlights existing research suggesting JAK inhibitors may be effective in treating inflammatory skin conditions like alopecia areata, atopic dermatitis, psoriasis, and vitiligo.

This review discusses the shift in toxicity profiles of cancer therapies from traditional chemotherapy to targeted agents, noting similar overall toxicities but with different side effects, and reports no new findings.

This review finds that vigorous aerobic exercise and resistance training may improve insulin sensitivity and androgen levels in women with PCOS, though more research is needed for definitive conclusions.

In this study, a deficiency in the zinc finger protein Zfp462 in mice led to anxiety-like behaviors and excessive self-grooming, providing a new model for studying anxiety disorders.

This review discusses the potential of Lansium domesticum as a herbal medicine, summarizing its traditional uses, nutritional value, bioactivities, and related nanoparticles and pharmaceutical formulations, but reports no new experimental results.

This article emphasizes the need for dermatology to treat gender identity, gender, and sex as distinct factors, aiming to improve patient-specific risk assessment and treatment alignment, and highlights a research gap in distinguishing sex and gender as separate risk factors in the field.

This review establishes a tolerable upper intake level of 255 μg/day for selenium in adults, warning that supplements and Brazil nuts may cause excess intake.

This study found that several preservatives, including triclocarban and triclosan, showed potential endocrine-disrupting effects on various nuclear receptors in both in silico and in vitro models.

This study demonstrated that thyroid hormone receptors play a crucial role in hair growth and skin health, as mice lacking these receptors showed impaired hair cycling and wound healing.

This consensus report outlines Brazilian dermatologists' recommendations for treating alopecia areata, highlighting intralesional corticosteroids for localized cases and systemic therapy for extensive, active disease, along with monitoring side effects.

This study identified key natural medicinal materials used in traditional Chinese medicine across Taiwan for inducing lactation, highlighting Angelica sinensis as a primary core component in galactogenous prescriptions.

This review examines the negative effects of anabolic-androgenic steroid use on the male reproductive system, including impaired testosterone production, sperm production issues, and adverse metabolic consequences without reporting new clinical results.

This study investigated immune dysregulation in individuals with Down syndrome and found that treatment with the JAK inhibitor tofacitinib improved skin conditions like alopecia areata and reduced autoimmune markers without severe side effects. Additional research is necessary to understand its broader impacts.

This study found that biliverdin beta and delta, metabolites of heme, play a critical role in Pseudomonas aeruginosa iron acquisition and cooperative behaviors, which are crucial for the bacterium's long-term infection in cystic fibrosis patients, suggesting potential targets for new therapies.

This study outlines treatment options for alopecia, suggesting intralesional corticosteroids for localized adult cases and Janus Kinase inhibitors for severe cases, emphasizing a balance between hair regrowth rate and managing side effects.

This review discusses the potential of a low-dose comprehensive cyclical nutrient therapy for enhancing hair growth and strengthening hair roots, but reports no new experimental results.

This study observed that individuals with Down syndrome exhibit early immune dysregulation, including multi-organ autoimmunity and hypercytokinemia, and found that the JAK inhibitor tofacitinib showed a good safety profile and reduced skin pathology in a Phase II trial.

This study suggests that the synthetic peptide SPIKENET (SPK) may protect against long-term skin alterations in mice following coronavirus infection, offering potential therapeutic intervention for similar effects in humans post-COVID-19.

In this animal study, applying a combination of inositol-stabilized arginine silicate complex and magnesium biotinate promoted hair growth but not nail growth.

This research observed that translation initiation shifts from cap-dependent to IRES-mediated pathways varied across tissues and cell types under stress and differentiation conditions in mice, with low IRES/Cap ratios signaling high stemness and potential multipotency, mediated by the RNA processing protein PTBP1.
