This case study reports that an infant with maple syrup urine disease developed acrodermatitis dysmetabolica due to low isoleucine levels, and increasing the isoleucine dose improved the condition.

This case report describes a rare instance where a child with nonketotic hyperglycinemia developed an acrodermatitis enteropathica-like eruption, likely due to combined zinc and branched chain amino acid deficiencies.

This investigation found that certain supplements, particularly whey protein isolate, growth hormones, and anabolic steroids, can negatively impact hair loss by affecting biochemical pathways.

This case study of a 2-month-old boy with maple syrup urine disease highlights the dangers of restricting branched-chain amino acid intake, as it led to acrodermatitis dysmetabolica-like skin eruptions and hair loss, later resolved with careful dietary adjustments and monitoring.

This research highlights dermatologists' concerns about the widespread use of sports supplements, noting that nutritional supplements associated with muscle-building and appearance enhancement can lead to dermatological issues like acne and alopecia, while potentially containing harmful substances such as undisclosed anabolic steroids.

This study discusses zinc's vital role in skin cell growth and how its deficiency can lead to acrodermatitis enteropathica, marked by symptoms like alopecia and dermatitis. It notes that similar symptoms appear in people with certain metabolic conditions, referred to as acrodermatitis dysmetabolica.

This study found that individuals with Alopecia Areata had distinct gut microbiome characteristics, including reduced species richness and specific microbial biomarkers, suggesting a potential link with oxidative stress.

This study found that a conditioner containing 18-MEA and SPDA can improve hair's smoothness and reduce flyaways, enhancing hair manageability.

This study found that serum amino acid profiles changed significantly following laparoscopic sleeve gastrectomy in patients with obesity, and identified serum leucine levels as an independent risk factor for postoperative alopecia.

This review discusses molecular signaling pathways and nutritional factors influencing feather growth and regeneration in poultry and offers no new results; the authors suggest these insights may guide strategies for producing superior plumage.

This study found that an 11-month-old Japanese infant developed biotin deficiency while on a Japanese amino acid formula without biotin, which was resolved with biotin supplementation.

Lacto-fermentation changes amino acid profiles in bovine colostrum, but results are inconsistent.

In this study on C57BL/6 mice, researchers found that cadmium chloride exposure led to metabolic disruption, accelerated skin aging, and impaired hair regeneration, with more severe effects observed at higher doses.

This study found that a more liberal intake of restricted amino acids in patients with methylmalonic acidemia resulted in improved growth and fewer illness episodes.

In this study, researchers found that an injectable solution of low-molecular-weight hyaluronic acid and amino acids significantly improved skin rejuvenation and elasticity in the labia majora of post-menopausal women over 12 weeks, with a reported 25% or greater aesthetic improvement and high patient satisfaction.

This review discusses the acyl-CoA synthetase very-long-chain (ACSVL) enzyme family, including its biochemical characteristics, tissue expression, and involvement in lipid metabolism, but presents no new experimental results.

The authors reported that a combination of amino acid and stem cell therapy may have extended survival in a dog with hepatocutaneous syndrome to 32 months post-diagnosis.

This consensus paper reviews expert opinions on treating telogen effluvium but reports no new clinical findings.

This study found that patients with tropical chronic pancreatitis exhibited significantly reduced plasma amino acid levels and antioxidant capacity, with folate deficiency identified as a key factor in hyperhomocysteinemia.

This study utilized a sequence-structure alignment approach to improve the characterization of Class A Rhodopsin GPCR superfamily, including orphan and unclassified receptors, through evolutionary analysis.

This source provides an overview of the dietary recommendations for macronutrient intake and the benefits of plant-based diets, including meeting essential amino acid needs through combining plant proteins and the advantages of consuming complex carbohydrates and adequate fiber for health.

This review discusses the role of metabolism in maintaining adult stem cell homeostasis with aging and highlights the potential benefits of dietary restrictions on stem cell function and longevity. It reports no new clinical results and emphasizes the need for further molecular studies.

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

This study reported that methanolic extracts of Capparis decidua fruits showed significant in vitro thrombolytic activity, suggesting their potential as a dietary health supplement for preventing thrombotic cardiovascular diseases.

This review investigates how the chirality of peptides affects their ability to form hydrogels, comparing the structural and mechanical properties of hydrogels made from homochiral and heterochiral peptides, and discussing their potential biological applications.

This study analyzed the molecular evolution and functional divergence of the Dkk gene family, finding accelerated evolution in Aves and Reptilia and identifying functional differences that may impact hair follicle development via Wnt signaling inhibition.

The authors concluded that liver transplantation in children with propionic acidemia can reduce the risk of metabolic decompensation and enhance quality of life, although some metabolic issues may persist.

This study found that valproic acid may interfere with the leucine metabolic pathway by inhibiting 3-methylcrotonyl-CoA carboxylase and biotinidase, which could contribute to side effects like skin rash and hair loss in patients.

This study found that unsaturated fatty acids are more abundant in the cortex of human hair than on its surface, and steryl glycoside-like lipids may help bind the cuticle to the cortex.

This study used molecular dynamics simulations to illustrate the complex molecular behavior of the hair surface F-layer, highlighting how fatty acids interact with 18-MEA under different conditions.
