This study found that the proteins GDNF, NTN, GFRα-1, GFRα-2, and c-Ret are differentially expressed during various stages of the human hair follicle cycle, with potential implications for hair biology.

The study's findings on omega-6 and hair loss are unreliable.

This study found that finasteride induced infertility and increased endoplasmic reticulum stress in rats, but these effects were mitigated by DA-9401 administration.

This source highlights that topical retinoids, particularly adapalene and its combinations, are crucial in treating acne due to their rapid action, sustained effects, and good tolerability; the study underscores the enhanced patient adherence with Deriva C MS gel for acne treatment.

This study found that among Chinese patients with alopecia areata, those with alopecia totalis or universalis had an earlier onset, longer disease duration, and more severe quality of life impact than those with patchy alopecia.

In this review, researchers explored the roles of vitamins A, B3, C, D, and E in skin immunity, highlighting their potential as therapeutics for skin diseases due to their antioxidant, anti-inflammatory, and antimicrobial properties.

This study found that cortisol increases mac25/IGFBP-rP1 expression in osteoblast-enriched cells from fetal rat calvariae, indicating transcriptional regulation which may influence IGF and insulin effects in bone.

This study found that female patients with frontal fibrosing alopecia are significantly more likely to have systemic lupus erythematosus compared to controls.

This study reported the first case of a NIPAL4 c.527C>A mutation in Romanian patients with autosomal recessive congenital ichthyosis, finding that NIPAL4 mutations are more common than TGM1 mutations in this population.

This study explored biochemical biomarkers in post-COVID-19 patients experiencing acute telogen effluvium, finding sex differences in blood characteristics and varying D-dimer levels by age, with elevated D-dimer showing correlations with inflammation markers.

This study investigated the use of spironolactone in patients with estrogen-dependent cancers, aiming to determine if it is linked to increased cancer recurrence risk, but results are not reported.

This study found that GFRα2 influences cell size but not survival or target innervation of Ret-positive low-threshold mechanoreceptors in mouse dorsal root ganglia, differing from its role in nonpeptidergic nociceptors.

This study reviews the evolution and modifications of microneedle drug delivery systems, initially designed for percutaneous use, now expanded for targeting a variety of tissues and organs such as ocular, oral mucosal, and gastrointestinal, suggesting widespread future applicability.

This study found that Secretory Phospholipase A2-IIA (sPLA2-IIA) promotes proliferation through JNK/c-Jun signaling, distinctively affecting normal stem cells and cancer cells, suggesting it as a potential target for cancer treatment.

This study discovered that a specific G to C mutation in the ornithine aminotransferase gene is linked to the retarded hair growth phenotype in mice and may serve as a model for human gyrate atrophy.

This article describes adult female acne as a complex condition affected by genetic, hormonal, and environmental factors, with hormonal therapies highlighted as particularly valuable for treatment.

This study found that subthermal CRET treatment increased keratinocyte proliferation and modulated cytokine production, affecting the inflammatory response in human keratinocytes through EGFR and ERK1/2/NF-κB pathways.

This narrative account, reported by C&EN, describes how Houston's use of a hormone-related hair loss treatment may have triggered unexpected panic attacks, contributing to ongoing mental health challenges, and highlights broader issues with mental health disorders that resist traditional treatments.

In this ex vivo and in vitro study, researchers found that capacitive resistive electrical transfer therapy increased cell proliferation and reduced cell death in hair follicles from patients with androgenic alopecia, suggesting potential benefits for alopecia treatment.

This study found that Danthron induced apoptosis in a human malignant melanoma cell line through mitochondrial, endoplasmic reticulum, and death receptor pathways.

This study found that 448-kHz Capacitive-Resistive Electrothermal Therapy led to a significant increase in hair density in women with Female Pattern Hair Loss, likely due to stimulated proliferation of dermal papilla cells.

In this study, subthermal RF-CRET currents were found to alter key molecular mechanisms in dermal papilla cells, promoting proliferation and survival while enhancing markers associated with hair growth and maintenance, suggesting potential benefits for hair regeneration.

This chapter defines skin integrity as a blend of intact structural elements and adaptable functional capacity, highlighting its importance in maintaining skin health across various conditions but reports no new research findings.

This review highlights the use of natural products in cosmetic-containing herbals for skin and hair care but reports no new clinical results, calling attention to their claimed curative properties and minimal side effects.

This study reported that applying a cream with 5% vitamin C reduced dermatoporosis-related purpura, suggesting the condition may be linked to vitamin C deficiency.

This study found that lack of sleep, increased physical activity, and alopecia were associated with a higher risk of COVID-19 infection, while low-dose alcohol intake, hand hygiene, and daily fruit consumption were linked to reduced morbidity.

This study suggests that short-term treatments with specific small molecules may enhance the differentiation potential and stem cell properties of human amniotic fluid stem cells.

In this study, Japanese patients with alopecia areata were found to have higher BMI and retinol intake, with retinol intake predicting severity of hair loss.

This article reviews the effects of vitamins, including A, C, D, E, and B, on animal fur, highlighting their roles in promoting healthy skin and fur condition by regulating cell renewal, metabolism, and collagen synthesis.

This study using Mendelian randomization found that higher levels of circulating β-carotene and α-tocopherol may reduce the risk of androgenetic alopecia, while α-tocopherol may also protect against alopecia areata, suggesting diet-derived antioxidants could aid in preventing non-scarring alopecia.
