This article reports on five cases of thallium poisoning seen at Hospital Dos de Mayo, Lima, Peru, highlighting the clinical symptoms and diagnostic features observed, including a case confirmed through various laboratory tests.

This study describes a case series of nine patients experiencing symptoms of selenium toxicity after consuming a liquid dietary supplement with an excess amount of selenium.

This case report highlights that a woman experienced arsenic toxicosis from kelp supplements, manifesting as alopecia and memory loss, which resolved after stopping the supplements.

This review highlights cobalt's essential role in vitamin B12 metabolism and its biomedical applications but also warns of health risks from high levels and environmental contamination, discussing remediation methods like phytoremediation.

This study found that TCDD significantly reduced EGF receptor binding in various animal models, linked to toxic symptoms like weight loss and developmental delays, with receptor phosphorylation persisting several days.

In this study, researchers found that TCDD exposure accelerated differentiation and altered gene expression in human epidermal cells, indicating the epidermal barrier as a target of TCDD-activated AHR.

In this study, TCDD administered to male rats down-regulated EGF receptor in liver plasma membranes and increased protein kinase activity, suggesting EGF receptor–mediated toxicological effects.

TCDD changes skin gene expression and may harm skin health.

This review discusses the biological effects and mechanisms of THSG in antiaging and related disease treatments but reports no new experimental findings.

This study found that a single application of TCDD on the skin of hairless mice altered epidermal differentiation, changing keratin expression patterns similarly to a known tumor promoter.

This review evaluates the anti-aging properties of TSG from He shou wu, finding it may protect against age-related diseases through multiple mechanisms, though further research is needed for clinical application.

In this study, researchers observed that TCDD exposure in mice enhanced sebaceous gland differentiation and lipid production before causing seboatrophy, providing insights into the cellular events that may contribute to chloracne pathogenesis.

This study found that both new and old formulas of DCP for treating alopecia areata resulted in similar hair regrowth, but tolerance was significantly better with DCP in isopropanol.

This study reports that A132, a hair dye ingredient, induces phototoxicity and photogenotoxicity via mitochondrial apoptosis when exposed to sunlight, suggesting potential risks of oxidative stress and hair damage.

This study found that SRD5a-3 is a highly efficient enzyme for converting hormones into androgens, with dutasteride being a much more potent inhibitor of SRD5a-3 than SRD5a-2.

This study found that A(3)B(5) downregulates melanin production and suppresses melanoma cell growth by promoting proteasomal degradation of TRP-2.

In this study, the researchers observed that post-radiation hair follicle repair in 3D architecture occurs through independent, long-range cell movements along the basal surface, resembling 2D healing processes.

The document recommends personalized, culturally sensitive treatments to rejuvenate the aging Asian face, focusing on natural results and specific techniques for skin, hair, and facial features.

In this study, l-Ascorbic acid 2-phosphate was found to stimulate hair follicle growth in vitro by promoting IGF-1 expression via the PI3K pathway.

In this study, testosterone was reported to increase aquaporin levels and water reabsorption in the kidneys of male rats, potentially leading to higher blood pressure, with effects mitigated by flutamide and finasteride.

CaBP1 and 2 are necessary for maintaining calcium currents and hearing in inner ear cells.

This study found that platelet-rich plasma injections followed by mesotherapy improved hair count and thickness in alopecia patients, with no significant side effects reported.

This abstract highlights that hair and nail disorders significantly affect quality of life, with early diagnosis and treatment critical to managing these conditions effectively.

This study reported that adipose stem cell exosomes, combined with microneedling, improved facial skin wrinkles, elasticity, hydration, and pigmentation compared to a placebo, with significant results on the Global Aesthetic Improvement Scale and no serious adverse events noted in treated individuals.

This chapter explores strategies for treating patients with early androgenetic alopecia using hair transplant surgery and emphasizes careful patient selection and conservative approaches but presents no new clinical findings.

This study identified a new enzyme, skin l‐tryptophan‐2,3‐dioxygenase, that may play a role in rat hair growth regulation, showing increased activity during peak hair growth periods.

This study found that trans-3,4'-Dimethyl-3-hydroxyflavanone reduces active TGF-beta2 levels in human keratinocytes, suggesting it may enhance hair growth by suppressing the TGF-beta2 activation pathway.

CaBP1 and CaBP2 are necessary for proper hearing and neurotransmission in the ear's inner hair cells.

CaBP1 and 2 are important for maintaining the activity of calcium channels necessary for hearing in inner ear cells.
