This case report describes a woman experiencing severe hair loss due to allergic contact dermatitis from a hair dye containing PPD.

This study found that biodegradable hyperbranched polyesters improved the solubility and loading capacity of hydrophobic drugs, with complete pyrene release achieved in 16 days under enzymatic conditions.

This study found that overexpression of OsPHR2 in rice leads to increased phosphate accumulation and root architecture changes even under phosphate-sufficient conditions.

This study found that the majority of "hypoallergenic" hair dyes still triggered allergic reactions in patients sensitive to para-phenylenediamine.

In this study, EPC-K, a compound with antioxidant and moisturizing effects, was found to decompose significantly under certain conditions, impacting its stability in quasi drug hair-growing products.

In this study on male rats, parachlorophenylalanine treatment induced hypersexual behavior and hair loss linked to increased social interaction but had no effect on brain serotonin when testosterone was used instead.

Aluminum phosphide poisoning can cause horizontal nail grooves and hair loss.

In this study, the aqueous extract from Phthirusa pyrifolia leaves significantly decreased testosterone levels in male Wistar rats without causing liver or kidney damage, suggesting potential effects on libido and reproduction.

PMS nanoparticles improve damaged hair by protecting and restoring its surface and color.

Phospholipid-coated nanoparticles penetrate hair follicles better than others, especially in pig ears.

This study suggests that PF-0998425 is an effective androgen receptor antagonist for sebum control and androgenetic alopecia with rapid metabolism reducing the risk of systemic side effects.

This review discusses recent molecular biology advances in the human phenol sulfotransferase gene family and reports no new results; the authors highlight its relevance for studies of endogenous and xenobiotic metabolism.

This research suggests that the enzyme Phospholipase D from E. coli is a strong candidate as the underlying cause of benign prostatic hyperplasia, potentially mediated by its conversion to lysophosphatidic acid in the prostate.

This review discusses the adverse effects of hair care products, highlighting irritation dermatitis and allergic contact eczema due to common allergens like paraphenylenediamine and glycerol monothioglycolate, but reports no clinical results.

This report describes eleven cases of thallium poisoning in individuals who consumed tortillas made from barley mixed with thallium sulphate, leading to symptoms including tingling, abdominal pain, vomiting, and limb weakness.

This report details a case study where a 40-year-old woman experienced allergic contact dermatitis and angioedema-like symptoms after using PPD-containing hair dye. Patch testing confirmed a positive reaction to PPD, highlighting the substance's potential to cause both T-cell and IgE-mediated hypersensitivity reactions.

In this study, novel substituted benzoyl benzoic acids and phenylacetic acids were potent and selective inhibitors of human steroid 5alpha-reductase type 2, with one compound showing promising bioavailability in rats for potential clinical evaluation.

This case report observed that despite treatment with Berlin blue and forced diuresis for thallium poisoning, a 42-year-old man experienced lasting distal polyneuropathy symptoms six months post-hospital discharge.

In this case study, divisional thallium intoxication in an adolescent led to progressive optic and peripheral neuropathy, with neurological deterioration occurring more rapidly after a second ingestion.

This study established a sensitive and reproducible method for determining the levels of four organic solvents in finasteride raw materials, meeting the requirements of the Chinese Pharmacopeia.

This study reports that mutations in human L-PGDS affect the entrance and exit of ligands in its binding cavity, suggesting these residues play a role in ligand interaction processes.

Certain ingredients in personal care products, like formaldehyde, oxidative hair dyes, and sulfates, pose health risks and need careful review.

This study found that GhPLDα1 in upland cotton may be involved in fiber development, correlating with increased hydrogen peroxide and cellulose biosynthesis during secondary cell wall thickening.

In this study, researchers developed a new Supported Ionic Liquid Phase palladium catalyst that showed effectiveness in aminocarbonylation reactions for synthesizing pharmaceutical compounds like CX-546 and a precursor of Finasteride, though results were sensitive to substrate variations and prompted palladium leaching concerns.

Researchers developed a method to detect hormone-blocking drugs in wastewater and found them in Beijing's sewage, suggesting they can survive sewage treatment.

In this study, researchers investigated the penetration and cellular responses to nanoplastics in human skin models with compromised barriers, finding that nanoplastics can penetrate the skin, accumulate in cells, and trigger inflammatory responses through specific signaling pathways.

This article discusses the symptoms, diagnosis, and treatment of thallium poisoning, with no new clinical results reported; the authors emphasize the importance of early suspicion for effective intervention.

Diphenyl ethers can potentially reduce excess oil production when applied on the skin, helping treat conditions like acne.

In this study, the gene SlPHL1 was identified as a transcription factor in tomatoes that enhances phosphate starvation responses by upregulating specific genes.
