This systematic review reports that there is currently no evidence supporting methotrexate for maintaining remission in ulcerative colitis; further large-scale trials are needed to assess its efficacy and safety.

This meta-analysis reports that intrauterine autologous platelet-rich plasma infusion improved outcomes like endometrial thickness and clinical pregnancy rate in women with thin endometrium, but further large-scale trials are needed to confirm these findings.

This study found that the structure and mineral content of dromedary camel hair, specifically the medulla patterns, medulla index, and elemental composition, change with age, revealing differences among camels aged 1 year, 3-5 years, and 8-10 years.

This randomized controlled trial found that intralesional injections of triamcinolone were significantly more effective than platelet rich plasma for treating alopecia areata on the scalp, although platelet rich plasma was considered a viable alternative due to its lack of serious side effects.

In this study, serum vitamin A levels were found to be lower in patients with alopecia areata compared to controls; however, the difference was not statistically significant, possibly due to the mild disease severity among participants.

In this study of patients with alopecia areata, researchers found that although serum vitamin A levels were lower compared to controls, the difference was not statistically significant. However, stress levels were significantly higher in the alopecia areata group.

Low-dose acitretin helps nail psoriasis, stem cells may treat scarring alopecia, Chinese men have lower baldness rates, lateral foldplasty is good for ingrown toenails, hair diameter helps diagnose female baldness, childhood trauma linked to alopecia areata, certain hair-weaving leads to scalp conditions in African American women, and new methods for hair research and understanding hair and sweat gland development were introduced.

In this study, the combination of castor or cedar oils with high-frequency treatment was associated with the growth of new hair, improved hair density, and increased hair strand thickness among patients with androgenetic alopecia, although it did not significantly affect scalp oiliness.

This study found that JAK inhibitors for alopecia areata showed promising response rates, with 72.4% of 289 cases responding, and oral administration achieving better outcomes than topical treatment, but recurrence occurred when treatment stopped. Further large-scale studies are needed to confirm these findings.

Alopecia totalis/universalis involves more intense immune activity and inflammation than patchy alopecia areata.

This study found that while molecular hair structures were nearly identical across individuals, genetic factors seem to influence specific lipid compositions, as seen in identical-patterned hair from parent-child pairs and identical twins, but not fraternal twins.

This study found that frontal fibrosing alopecia and lichen planopilaris have similar histopathological features, but FFA exhibits more prominent apoptosis and less inflammation with spared interfollicular epidermis.

People with primary cicatricial alopecia have a higher risk of heart disease and stroke.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

This study found that matrix cells from normal hair follicles primarily had a 2C DNA content, while those in androgenetic alopecia showed a significant increase in cells with a higher DNA content.

Women with excessive hair growth often have hormonal issues and need medical advice and treatment.

This study observed that inflammation in androgenetic alopecia samples was similar to alopecia areata controls, but infundibular and isthmic inflammation were significantly more common in androgenetic alopecia cases.

This study suggests that decreased expression of thioredoxin reductase 1 in hair follicle cells may contribute to glucocorticoid resistance in some alopecia areata patients by affecting the intracellular redox system.

In this study with a rat muscle defect model, decellularized muscle matrix demonstrated better integration, neovascularization, and myogenesis compared to commercially available acellular dermal matrices, and also showed trends toward reduced inflammation and fibrosis after 30 and 60 days.

In this study, no association was found between the AR gene and type II androgenetic alopecia in Egyptian women, suggesting it is not a useful biomarker for predisposition.

This study found that anagen skin in PVG rats showed significantly smaller wound diameters compared to telogen skin at 7 and 8 days after wounding, suggesting the importance of hair follicle dermal components in wound healing.

Immune system issues may contribute to female pattern hair loss.

East and Southeast Asians typically have less dense but thicker, straight black hair.

In this study, Raman micro-spectroscopy did not support the hypothesis of structural changes in hair follicles due to miniaturization in women with androgenetic alopecia.

This study found that longer disease duration in psoriasis patients was significantly associated with increased incidence of cerebral atrophy, suggesting a potential need for central nervous system screening in these patients.

This article discusses various mechanisms for promoting hair growth in pattern hair loss and highlights the challenge of balancing short-term measurable results in trials with the need for long-term efficacy data.

This study identified a shared gene signature in scarring alopecia subtypes, with increased mast cell presence, suggesting similar treatment approaches may be effective across these hair loss disorders.

In this study, hair follicle transplantation into nonhealing ulcers promoted rapid wound closure, with differing scar quality and hair growth between the central and peripheral wound areas.

This study found that localized skin calcification could be induced in adult rats through dihydrotachysterol treatment combined with topical trauma, offering an experimental model for calcifying scleroderma.

This paper introduces a hypothesis that elevated DHT at puberty may increase cerebral heat output, creating chronic thermal stress linked to androgenetic alopecia, and suggests this could be tested with MR thermometry.
