The document concludes that doctors should recognize congenital triangular alopecia to avoid unnecessary treatments, as it does not respond to steroids like alopecia areata does.

This study suggests that a specific region upstream of the TGF-β1 gene may play a key role in androgenetic alopecia by regulating gene expression in a cell-specific manner.

This study found that biodegradable hydrogels loaded with various growth factors significantly enhanced hair follicle growth and blood vessel formation in mice, demonstrating a positive effect on their hair growth cycle.

This research overview discusses Post-Finasteride Syndrome, presenting data from an FDA database, but it does not report any new clinical findings.

This study demonstrates that bioengineered lacrimal gland germs can successfully develop and restore tear production and ocular surface protection in a mouse model with lacrimal gland dysfunction.

This review discusses the role of epidermal and other adult stem cells in skin repair, focusing on their potential therapeutic applications for non-healing wounds and other skin disorders, but reports no new research results.

This review discusses advances in understanding mammalian stem cell niches, particularly in bone marrow, tooth, and hair follicle, and highlights the potential for developing therapies targeting these niches for tissue repair.

This study found significant species differences in the enzyme activity and inhibitor affinities of prostatic 5α-reductases from rats, dogs, and humans, with variable potencies for different 3-oxo-4-azasteroid inhibitors across species.

This study demonstrates the potential of using bioengineered follicles from adult tissue-derived stem cells for fully functional hair regeneration, illustrating possible applications in organ replacement therapy.

This study demonstrates that bioengineered salivary gland transplants can fully regenerate gland function, producing saliva and restoring normal swallowing in salivary gland-defective mice, offering potential for xerostomia treatment.

This study reported that transgenic mice with targeted TNF alpha expression in keratinocytes showed impaired weight gain, retarded hair growth, and skin changes, leading to cachexia and necrosis.

This study found that feeding aged mice a probiotic yogurt induced changes leading to thicker, healthier fur, suggesting a bacteria-triggered interleukin-10-dependent mechanism that mimics signs of youth and reproductive fitness.

This review discusses the extraction, purification, modification, and biological activity of polysaccharides from Traditional Chinese Medicine and reports no new research findings.

This review discusses the isolation, structure, and bioactivity of lignans and neolignans from 2016 to mid-2018, reporting no new clinical results but highlighting their potential protective properties against diseases such as cancer and neurodegeneration.

This study observed that human hair follicles were able to regenerate fiber-forming structures after the bulb was amputated and transplanted onto athymic mice, suggesting a general regenerative capacity.

This study found that hair thickness and density increased after treatment with human follicle mesenchymal stem cells and platelet rich plasma, associated with enhanced Wnt signaling and platelet derived growth factors.

This article proposes a hypothesis for alopecia areata hair loss patterns and provides epidemiological evidence supporting distinct hair loss characteristics between general cases and those with androgenetic alopecia; it presents no new clinical results.

This study found that Atlantic croaker nuclear androgen receptors AR1 and AR2 have different binding affinities for androgens, suggesting that they may mediate distinct physiological actions in teleosts.

This review discusses photothermal agent hybrids in hydrogels for antibacterial action, angiogenesis, and osteogenesis in tissue engineering, but reports no new experimental findings.

In this study, expressing human K16 in the epidermis of K14 null mice prevented early skin blistering but led to age-related anomalies, indicating K16 and K14 have distinct roles despite their sequence similarity.

This review examines the role of steroidal inhibitors in treating prostatic diseases but presents no new clinical results.

In a study on muscle regeneration in mice, researchers found that platelet-secreted CXCL7 is crucial for recruiting neutrophils to injury sites, aiding early muscle repair and optimal regrowth, suggesting potential therapeutic uses for boosting muscle healing.

This study found that trichohyalin, a protein previously thought to be restricted to hair and tongue, is also present in isolated cells within the granular layer and stratum corneum of normal human epidermis.

This study found that self-noncoding dsRNA activates TLR3 to stimulate intrinsic retinoic acid synthesis, promoting new hair follicle formation in wounded mice and showing similar gene expression changes in humans treated with rejuvenation lasers.

This review discusses advancements in the use of microneedle arrays and nanoparticles for transdermal delivery of therapeutics, noting challenges in overcoming the skin barrier and summarizing recent clinical trial achievements in areas like cancer therapy and gene therapy.

This study found that newly synthesized steroidal trienones demonstrated stronger 5α-reductase inhibitory activity compared to dienones in various biological models, suggesting potential for developing enhanced antiandrogenic drugs.

This review explores how colloidal drug delivery systems can enhance the stability, absorption, and bioavailability of phytochemicals, potentially rediscovering ancient compounds' therapeutic benefits and overcoming limitations like poor solubility and bioavailability.

This review outlines the main findings from clinical trials on teriflunomide's efficacy and safety for relapsing multiple sclerosis, noting clinical considerations and exploring its mechanisms based on various studies.

Testosterone was found to inhibit hair follicle epithelial cell proliferation in adult stumptailed macaques only when dermal papilla cells from bald scalps were present, and this effect was reversed by the antiandrogen RU 58841.

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.
