This review discusses the uses and toxicological data of eleven unsaturated halogenated hydrocarbons, including dichloroacetylene, allyl chloride, hexachlorobutadiene, β-chloroprene, vinyl chloride, trichloroethylene, and perchloroethylene, but presents no new findings.

This study evaluated laser excision of the fibrous band for oral submucous fibrosis treatment, noting that while it offers immediate relief, long-term effects require further evaluation due to potential drawbacks.

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 by Gao et al. reports that two nonsteroidal selective androgen receptor modulators, S1 and S4, demonstrated tissue-selective actions in rats, suppressing prostate growth while maintaining muscle growth without altering hormone levels.

Selenium supplements may reduce mercury levels in the hair of city dwellers in China.

Using Selenium Disulfide shampoo weekly helps prevent scalp dermatitis flare-ups.

This case report describes a rare patient with Sjogren's syndrome who experienced recurrent pneumothorax, resolved through surgical intervention, highlighting pneumothorax as an unusual complication of the condition.

This study found that using a combination of iontophoresis and liposomal delivery facilitated the effective intradermal administration of superoxide dismutase in rats, reducing oxidative skin damage from UV exposure.

Fungi-produced compounds can change plant root growth.

This study suggests that nanoliposomes encapsulating saw palmetto CO2 extract could be effective for delivering drugs to treat hair loss due to their small size, dispersion, and negative charge.

In this study, researchers identified specific Se6OMT enzymes in *S. epigaea* involved in the cepharanthine biosynthetic pathway, providing insights into their substrate promiscuity and essential genetic components for metabolic engineering and synthetic biology applications of cepharanthine production.

This study found that oral administration of solubilized sturgeon oil in mice promoted hair growth and positively influenced the gut microbiome associated with hair growth promotion.

This review discusses the role of steroid sulfatase in steroid hormone metabolism and highlights the need for more research on its expression and regulation, especially regarding hormone-dependent tumors.

In this study, sodium thiosulfate was observed to promote hair growth in mice by encouraging hair follicles to enter the growth phase and complementing the effects of minoxidil, suggesting potential benefits for hair loss treatment.

This study found that COX-2 expression in normal rat skin is linked to the hair cycle, with varying levels observed in different skin structures during anagen, catagen, and telogen phases.

This study found that exposure to hair bleach aerosols containing persulphates and hydrogen peroxide induced airway hyperresponsiveness to acetylcholine in rabbits.

This study found that applying superoxide dismutase (SOD) gel on mice protected against hair graying caused by UV-A and psoralen exposure, suggesting photosensitization may be a factor in hair aging.

This review discusses the link between selenium levels in the environment and related diseases in China, reporting no clinical results; the authors highlight the need for clearer geographic risk and remediation strategies.

In this study, PFOS exposure altered steroid hormone levels and enzyme activities related to steroidogenesis in juvenile Silurana tropicalis, with effects differing between male and female frogs.

In this study on Sprague-Dawley rats, 0.60 mg/kg doses of L-Se-methylselenocysteine and sodium selenite were associated with liver toxicity and reduced sperm motility, while Se-enriched peptides showed no observable adverse effects up to 0.60 mg/kg.

This study found that peach kernel oil extracted via supercritical fluid extraction had higher quality and antioxidant properties than oil obtained by other methods, effectively protecting human hair follicle keratinocytes from oxidative damage.

In this study, utilizing a mixture of crushed sky fruit seeds and sodium salt for goat skin preservation led to a significant reduction in environmental impact, decreasing total dissolved solids by 59% and chloride content by 44%, while maintaining the physical quality of processed leather.

This study concluded that rosemary essential oil rich in terpenes was successfully extracted using vacuum-assisted hydrodistillation, and Solid Phase Micro Extraction was superior for identifying volatile compounds compared to direct injection.

Human enzymes can detoxify harmful substances but might also increase their cancer risk.

This study identified a fungal sulfotransferase enzyme, FgSULT1, from *Fusarium graminearum*, expanding the sulfotransferase superfamily and offering new biocatalytic methods for producing bioactive sulfates.

This study found that neither a single application nor prolonged exposure to selenium sulfide had a significant effect on hair growth or rest phase percentages.

This study found that in laboratory rats, toxic concentrations of hydrogen sulfide affected the immune system differently depending on age and immune suppression status, with notable changes in immune cell levels and phagocytosis, suggesting significant roles in age-associated pathologies.

This article discusses androgenetic alopecia's mechanisms but reports no new study results.

This study observed that the intestinal absorption of selenium varies depending on its chemical form, with selenomethionine being absorbed efficiently and selenium as selenodiglutathione or selenodicysteine being absorbed faster than selenite.
