This case report describes a patient with eosinophilia-myalgia syndrome who experienced severe, persistent telogen effluvium.

This review discusses the emergence and impact of eosinophilia-myalgia syndrome related to L-tryptophan and offers insights into environmental factors affecting sclerodermatous conditions, with no new research findings presented.

This study found that using histidine-tryptophan-ketoglutarate solution with adenosine triphosphate and deferoxamine for hair graft preservation significantly reduced postsurgical shedding compared to Ringer solution, enhancing patient satisfaction.

This study identified over 40 phytochemical compounds in the leaves and flowers of Bituminaria bituminosa, predominantly glycosylated flavonoids from apigenin, using advanced chromatographic techniques.

The authors concluded that newly synthesized N-acyl-L-tryptophanyl-isoleucine amides showed high anxiolytic activity in animal models, comparable to diazepam, through interaction with the TSPO receptor.

This case report describes a patient with eosinophilia-myalgia syndrome related to L-tryptophan use, detailing the specific symptoms and laboratory abnormalities observed.

In this study, researchers found histopathological similarities between L-tryptophan eosinophilic myalgia syndrome and idiopathic eosinophilic fasciitis, with certain unique inflammatory features present in the former.

This review updates the protective effects and molecular mechanisms of melatonin against ultraviolet-induced damage in human skin, reporting no new clinical findings.

This study identified multiple mutations in the 5 alpha-reductase-2 gene among male pseudohermaphrodites in the Dominican Republic, suggesting they do not share a common ancestry.

In this study, male Wistar rats with obesity showed reduced depressive-like behaviors, brain inflammation, and oxidative stress after long-term finasteride treatment, suggesting potential benefits of finasteride in obese conditions, while lean rats experienced adverse effects including metabolic disturbances and depressive-like behaviors.

This review summarizes proposed pathophysiological mechanisms of postpartum depression, highlighting neuroendocrine and neurobiological changes, but reports no new findings and calls for integrated understanding of the disorder.

This study suggests that enhancing glycolysis in MSCs may improve their immune functions and therapeutic potential, although more evidence is needed to understand the direct metabolic mechanisms involved.

This study found that Arabidopsis mutants with disrupted auxin conversion pathways displayed low auxin phenotypes and increased biosynthetic gene expression, suggesting a feedback mechanism maintains auxin homeostasis.

This study found that chemical treatments like perming, dyeing, and bleaching significantly alter amino acids and lipids in human hair, which may impact hair strength and quality.

A new genetic mutation in mice causes permanent hair loss and skin wrinkling.

Losartan can cause temporary loss of taste.

This article reviews studies on younger men using finasteride for hair loss, finding persistent sexual and nonsexual side effects like erectile dysfunction and depression, and reports lower neurosteroid levels in affected individuals.

Merino wool fibers change shape with moisture, while human hair shape stays the same.

This study found that mouse skin can produce and metabolize serotonin and N-acetylserotonin, with activity influenced by location, physiological skin status, cell type, and mouse strain.

This article reviews the toxic effects of mimosine in Leucaena leucocephala and discusses various methods to mitigate its toxicity but presents no new findings.

Certain fungi and bacteria help orchid seeds germinate and plants grow better.

This study found that murine skin is a target for melatonin bioregulation, as melatonin affected DNA synthesis and tyrosinase activity in skin organ culture.

This study found that the PLC2 gene plays a critical role in auxin-mediated root development in Arabidopsis, influencing root growth and PIN2 distribution.

This review discusses the potential of bioprinting technology in cosmetology, particularly for improving skin functions like pigmentation restoration and hair follicle development, but reports no new clinical findings.

This animal study found that second generation mice exposed to excess zinc during gestation and lactation had reduced plasma copper, body weight, and hematocrit, with lighter and delayed hair development compared to mice on a normal zinc diet.

This study developed a micellar electrokinetic capillary chromatography method for determining minoxidil in Rogaine and generic products, offering a simple and efficient alternative to HPLC.

This chapter reviews existing knowledge about melatonin's MT₁ and MT₂ receptors in human tissues, discussing their established and potential functions, but reports no new clinical findings.

This study reviews melatonin's diverse roles in dermatology, highlighting its potential to protect skin from UV damage and oxidative stress, enhance DNA repair, and influence hair follicle cycling, suggesting therapeutic applications in skin care and hair renewal.

In this study of women with female pattern hair loss, iron deficiency was associated with the condition due to significantly lower serum ferritin and altered hematological indices compared to healthy controls, while no significant differences in serotonin levels or renal function were observed.
