In this case report, a 13-year-old boy's acute appendicitis revealed Crohn's disease after unsuccessful conservative management required surgery, highlighting the diagnostic value of histopathological examination of the appendix.

This case study observed that hijāmah bil shart (wet cupping) led to significant improvements in hair texture, reduced shedding, and overall scalp health in a 34-year-old male with androgenetic alopecia, with no adverse effects.

This study found that St. John's wort treatment for two weeks induced finasteride metabolism and reduced its plasma exposure in healthy men.

This article reviews evidence suggesting that vitamin D may help manage Hashimoto’s thyroiditis by affecting immune pathways and improving thyroid function, though more research is needed to fully understand its therapeutic potential.

This review discusses the pathogenesis of common sebaceous gland diseases and their molecular pathways, but it reports no new clinical findings.

This review explores the detrimental effects of sunlight on the skin’s circadian rhythm and photodamage, noting the potential of natural cosmeceuticals to influence this rhythm, but reports no new results.

In this review, the researchers reported that 5α-reductase inhibitors demonstrated neuroprotective effects and reduced dyskinesias in animal models of Parkinson's disease, suggesting their potential for repurposing to manage symptoms in men with PD.

This study investigated the effects of pathological α-synuclein on sebaceous gland cells in Parkinson's disease, finding that α-synuclein exposure altered cellular differentiation and lipid production, suggesting a potential link between α-synuclein and lipid dysregulation in the skin of PD patients.

In this study, tea tree oil was found to have substantial antibacterial activity and promote proliferation and migration of hair follicle stem cells in vitro, indicating potential benefits for treating scalp alopecia areata.

This study found that an aqueous extract of Bacopa procumbens improved motor function and preserved neuronal structure in a mouse model of Parkinson's disease, suggesting its neuroprotective potential.

Pili annulati is caused by a protein metabolism disorder affecting hair structure.

This study observed that mercury-lamp irradiation may cause cleavage of disulfide bonds in keratins of white hair, leading to the formation of thiols in laboratory settings.

This study found that UV radiation exposure increased protein elution and altered protein characteristics in hair fibers, suggesting environmental factors impact hair shaft proteins.

This study found that EDA and EDAR are expressed throughout cashmere goat fetal development and play a critical role in hair follicle formation by influencing gene expression in fibroblasts and epithelial cells.

This study found that a quinazoline derivative, SH-340, increased skin barrier-associated factors and inhibited TSLP expression and STAT6 phosphorylation in human primary keratinocytes, suggesting potential benefits for alleviating inflammation and improving skin barrier function in atopic dermatitis.

This study found that hair care products containing fermented papaya, fermented mangosteen, and caffeine significantly inhibited hair loss, increased hair density and thickness, and improved hair follicle structure in individuals with androgenic or diffuse alopecia over three months compared to placebo and caffeine controls.

This study found that human hair shows progressive damage from UV and gamma radiation exposure, with fluorescence intensity serving as a sensitive measure of radiation-induced changes.

This study found that combined dietary supplementation of sodium hyaluronate and eggshell membrane was associated with various improvements in skin and coat health markers in healthy Ragdoll cats.

In this study, dogs with adrenal-dependent hypercortisolism showed a decrease in the prevalence of systemic hypertension from 79% to 25% after a year of trilostane treatment or adrenalectomy, with blood pressure normalization observed by three months post-surgery in hypertensive dogs.

This study observed no significant relationship between previous hair restoration procedures and follicular transection rates in revision FUE, but noted potential trends worth investigating in further research.

This study observed that sebaceous gland atrophy in psoriatic lesions correlates with the down-regulation of specific lipid biosynthetic gene modules, potentially affecting hair appearance without damaging follicles.

This study developed a multifunctional 3D-printed hydrogel scaffold, SH-EGCG, that showed promising results for repairing infected diabetic wounds; in lab and animal tests, it demonstrated antibacterial activity, enhanced wound healing, and improved tissue regeneration and remodeling through various supportive mechanisms.

In this mouse study, researchers found that orally administered low-molecular-weight fish collagen peptides significantly improved hair regrowth by both enhancing growth-promoting pathways and reducing inhibitory mechanisms.

This infographic compares the safety profiles of SH‑1, a cosmetic ingredient, which showed no systemic absorption, and PP405, an investigational drug with dose-dependent systemic uptake and potential threshold breaches, highlighting differences in safety between cosmetic and investigational substances according to this report.

This article discusses the effectiveness and indications of sex hormone therapy for various skin disorders and emphasizes the importance of avoiding androgen-effective contraceptives, but reports no new clinical results.

This study developed a biocompatible hair-dyeing technology using a dark polyphenol complex, which demonstrated effective hair coating, improved mechanical strength, and strong antioxidant properties while maintaining high cell viability.

This study found that patients with androgenetic alopecia had higher serum homocysteine levels, linked to the mutant MTHFR genotype, and an increased risk of coronary heart disease.

This review discusses the roles of metabolism, reactive oxygen species, intracellular pH, and cell morphology in influencing cell fate decisions during stem cell differentiation but reports no new experimental results.

This study observed that dandruff in Indian women is associated with a distinct scalp microbiome, including specific bacterial and unknown Malassezia species, with implications for nutrient homeostasis and cell-host adhesion pathways.

This study found that a newly constructed composite hydrogel dressing, made from silk fibroin, chitosan, and halloysite, promoted hair follicle neogenesis, angiogenesis tissue regeneration, and scar reduction.
