This study suggests that reversible hypopigmentation in homocystinuric patients may result from tyrosinase inhibition by homocyst(e)ine, with in-vitro experiments showing copper sulfate reversing this inhibition.

This review discusses zinc's role as an essential trace element in human nutrition, particularly its importance in total parenteral nutrition, and reports no new clinical results.

This study found that topical minoxidil and diazoxide induced significant hair regrowth in bald macaques, while a steroid 5 alpha-reductase inhibitor prevented baldness in preadolescent macaques.

This study investigated how dietary copper affects hair pigmentation and mineral concentrations in calves, reporting on copper's influence but not providing definitive results.

This study observed significant differences in trace element hair-scalp concentrations associated with atherosclerosis in coronary and carotid disease patients, suggesting that zinc levels and lymphocyte count interactions may significantly influence cardiovascular disease development.

This study found that high molybdenum levels in the diet, especially with added sulfate sulfur, led to symptoms like alopecia and hair color loss in heifers; however, these were corrected by adding copper.

This study found that supplementing pregnant and lactating mice with high dietary copper improved survival and physical traits in mice carrying the crinkled mutation, suggesting copper's role in modulating gene expression.

This study found that living environment significantly influenced Fe concentrations in dog and cat hair, with outdoor animals showing higher levels than those kept indoors.

This study found that although soil and forage in Middle Paraíba, Brazil, contained normal to high copper levels, the surrounding bovine populations showed signs of copper deficiency likely due to antagonistic effects from high iron, zinc, and manganese levels.

This review discusses various potential adverse effects of common oral vitamin and mineral supplements used in dermatology and highlights lesser-known issues like hematologic and neurologic effects from zinc.

This review reported that while glycyl-L-histidyl-L-lysine tripeptide copper complex (GHK–Cu) has limited skin permeation when used alone, liposomes may enhance its absorption, but there is limited research on this aspect, highlighting a need for further studies.

This study reported a green synthesis method for copper oxide nanoparticles using pumpkin seed extract, achieving significant antibacterial activity against Bacillus subtilis and moderate cytotoxic effects against certain cancer cell lines, indicating potential biomedical applications for these eco-friendly nanomaterials.

The researchers concluded that while swine hair mineral content is influenced by dietary levels, the variability and interaction between minerals suggest it may not be a reliable indicator of an animal's overall mineral composition.

This narrative review highlights the crucial role of micronutrients and gut microbiota in thyroid function and suggests that nutritional imbalances may contribute to thyroid dysfunction or diseases.

This article reviews recent developments in microneedles combining metallic elements and herbal compounds for wound healing, highlighting their benefits such as enhanced therapeutic efficacy and reduced toxicity, and offering a reference for future advancements in this technology.

This study reported that green tea extract may promote the excretion of copper into the hair in mice.

This review explores the biology of wool follicles and suggests their potential use as research models in modern biology, but it reports no new findings.

This review discusses the genetic and androgen-related factors in androgenetic alopecia, highlighting a specific polymorphism in the AR protein associated with male pattern hair loss, and reports no new clinical results.

This study highlights the role of platelets in immune interactions and severe adenovirus infection, noting that activated platelets have a shorter lifespan. Results suggest potential for developing therapies targeting platelet senescence and immunologic mechanisms.

In this study, researchers observed that patients with Alopecia Areata had significantly lower serum zinc and higher copper levels compared to healthy controls, indicating a disrupted zinc-copper balance that may contribute to the disease's pathogenesis.

This study suggests that certain Dibenzo derivatives may be promising candidates for prostate cancer treatment due to their potential interactions with the androgen receptor and 5α-reductase enzyme.

This study found that moisture sorption properties of wool and hair fibers from various animals were similar, despite different structural features, with sorbed water being more ordered than liquid water.

This study found that feeding mice high levels of dietary vitamin A increased WNT signaling, which activated hair follicle stem cells and may have accelerated alopecia areata progression.

This review discusses the role of flavonoids and Nod factors in the symbiosis between legumes and rhizobia and reports no new results; the authors argue this knowledge could enhance sustainable agriculture.

In this study, researchers observed that dormant TRP-2+ melanoma cells in bone marrow can interact with CD8+ T cells in tumor-bearing ret transgenic mice, potentially influencing immune responses.

This study identifies two new proteins, CCDC22 and CCDC93, essential for root and root hair growth in Arabidopsis, and demonstrates their genetic link to a VTI13-dependent vacuolar trafficking pathway.

This thesis explores both environmental and genetic factors in prostate cancer, focusing on surrogate hormone markers, medical radiation, family history, and genetic polymorphisms related to DNA repair and hormone marker genes, but reports no new clinical findings.

This study found that adipose-derived mesenchymal stem cells produced more anti-inflammatory and pro-angiogenic cytokines on electrospun scaffolds, which enhanced wound healing and macrophage activity in a rat model.

This chapter provides an overview of the complex chemical and physical structure of the hair surface, detailing how factors like ethnicity, environmental stress, and cosmetic treatments can alter its properties and influence the adhesion of hair care products.

This study found that higher concentrations of copper (II) ions in human hair increase protein oxidative modification, contributing to hair damage regardless of UV exposure and pigmentation level.
