In this study, cross-sex hormone therapy affected hair growth patterns differently, with estrogen reducing hair growth in male-to-female transsexuals and testosterone increasing it in female-to-male transsexuals; however, male typical hair diameters were not fully reached in the latter group after 12 months.

This review provides a comprehensive guide to serum-free human hair follicle organ culture methods, highlighting research opportunities, standardization efforts, and potential applications without reporting new empirical findings.

This study indicated that while testosterone replacement in older men with low testosterone increases muscle mass and strength and reduces fat, its effects on physical function, disability, falls, or fractures remain unclear.

Human enzymes can detoxify harmful substances but might also increase their cancer risk.

This article reviews the classification, diagnosis, and management of hair disorders, emphasizing the role of trichoscopy and early diagnosis for effective treatment but reports no new clinical findings.

This review evaluates hair growth measurement methods for human scalp hair, suggesting that combining highly resolutive analytical approaches with global calibrated methods is recommended for assessing hair changes in clinical settings.

This article reviews treatment options for cutaneous T-cell lymphoma, including skin-directed therapies and aggressive treatments for advanced cases, but reports no new clinical results.

This source reports that scalp cooling is currently the only safe and FDA-cleared method to potentially reduce chemotherapy-induced hair loss, with about a 50% chance of maintaining sufficient hair to avoid needing a wig.

In this study, adding δ34S isotope analysis to models modestly improved precision in estimating grizzly bears' salmon and terrestrial diets, but contributed little new information.

Scalp hair grows at 0.37 mm/day, forearm hair at 0.18 mm/day, and thigh hair at 0.30 mm/day, with no significant differences found in people with certain hair conditions.

Minoxidil lowers blood pressure more effectively but has more side effects, so try hydralazine first.

This study found that the growth of hair ice on dead wood requires the biological activity of a winter-active fungus, specifically Exidiopsis effusa, which shapes and stabilizes the ice structures.

This study reported the feasibility of detecting six cell-cycle-related nuclear markers in plucked human scalp and eyebrow hair, providing valuable insights for future intervention studies.

This article reviews the evidence regarding the role of sex hormones in occult hyperadrenocorticism and reports no new findings, highlighting the unproven nature of their involvement.

This study found that follicular density and various hair growth ratios differ statistically between nonscarring and scarring alopecia, though significant overlap exists due to factors like sample size and scalp variation.

This study found that partial follicular units extracted from the donor area can survive and regenerate new hairs at their original site and when transplanted, effectively creating two hair follicles from one.

This review summarizes existing knowledge of how the WNT signaling pathway affects mesenchymal stem cells under various conditions, highlighting challenges and mechanisms for clinical applications.

This article highlights that rivaroxaban, commonly associated with bleeding risks, may also cause rare non-bleeding adverse effects like liver injury and hypersensitivity.

This review discusses the potential of follicular drug delivery systems to target the pilosebaceous unit and reports no new research findings.

This study found that redheaded individuals had higher levels of vitamin D precursor 25(OH)D3 compared to non-redheaded individuals, suggesting a physiological adaptation to low UVB radiation in Europe.

This article reviews the identification and assessment of cutaneous drug reactions, emphasizing the importance of early recognition and the need for accurate diagnosis to prevent serious complications; it reports no new clinical results.

Different stem cells have benefits and challenges for tissue repair, and more research is needed to find the best types for each use.

This study evaluated a new computer-aided detection system for identifying Breast Arterial Calcification in mammograms, achieving 70% accuracy, but highlighted the need for a larger dataset to explore its relationship with cardiovascular diseases.

This study observed that pantethine, a vitamin B5 precursor, attenuates tumor growth in immunocompetent mice by enhancing antitumor immunity, but its effect is limited by immune cell exhaustion over time.
