This review discusses Ganser syndrome as a rare and misunderstood disorder within psychiatric practice, noting its exclusion from the DSM-5 and potential dual origins as organic or psychogenic.

This study examined the morphometric features of hair from different regions of India to identify potential regional characteristics.

This study established a protocol using anti-steroid antibodies to differentially label epidermal cell contributors, suggesting potential applications in simplifying complex trace DNA mixtures before profiling.

This review discusses the formulations, mechanisms, and physiological aspects of hair cosmetics and types, but reports no new results, suggesting a foundation for future hair research.

Hair cortisol measurement is a promising, non-invasive tool for monitoring cortisol exposure over time.

The document concludes that while some advocate for a patient voucher system, it may be unequal and current healthcare reforms should be given a chance, and it also recommends various medical books for their comprehensive coverage and advice on specific health issues.

The book has valuable information but is hard to read due to poor writing.

Doctors should set boundaries and seek outside help for family medical issues.

This study used proteomic profiling to reveal significant individual and site-specific differences in human hair shaft proteins, which may improve the differentiation of hair based on ethnic origin and individual identity.

This review highlights that human hair is a valuable biological matrix for clinical and toxicological analyses, demonstrating its applicability in detecting various active substances from different pharmacological classes.

This study found that rhodamine B penetrated human hair fibers more effectively from an aqueous solution compared to a methanol/ethanol solvent, with penetration depending on hair morphology.

This study found that codeine incorporation in guinea pig hair varied with pigmentation and was highest in black hair, suggesting the role of eumelanins in drug binding.

This in vitro study found that opiate diffusion was more pronounced in damaged hair fibers than in undamaged ones, with high opiate concentrations detected in fiber centerpieces.

This review concludes that anabolic–androgenic steroid abuse may lead to significant neurotoxicity, affecting brain structure, neurotransmitter systems, and increasing the risk of mood disorders and cognitive deficits.

This study found that specific DNA variants in the TCHH, WNT10A, and FRAS1 genes are associated with predicting straight hair in Europeans, showing high sensitivity but low specificity, especially using a neural networks approach.

This study found that using trait prevalence-informed priors may improve the prediction accuracy of appearance traits in Bayesian models, but their application is limited by sparse knowledge on trait prevalence.

This study found that the RapidHIT™ ID system can successfully obtain DNA profiles from single hair roots, particularly those with high nuclei counts.

This article presents a biochemical model to explain how drug molecules are incorporated into hair, highlighting factors such as drug melanin affinity and the role of physico-chemical properties.

This review discusses fetal hair follicle development and its importance for determining in utero drug exposure through neonatal hair, but it reports no new clinical results.

This study found that different decontamination protocols caused varying levels of cuticle damage in hair, with aqueous buffer treatment resulting in the most substantial degradation.

This study found that in vitro heat straightening of hair reduced THC and cocaine concentrations but increased CBN and BZE levels, suggesting heat conversion of these substances.

This study reported that clozapine and its metabolite showed a preference for binding to pigmented hair, but were also detectable in non-pigmented hair of patients with Parkinson's, with high correlations between dose and hair concentration.

This study found that two pre-Hispanic mummies from the Andean coast had well-preserved hair with significant amounts of heavy metals like iron, lead, bromide, and occasionally arsenic, revealing their historical context.

This study found that postmortem root banding in hair is likely due to the degradation of the intermacrofibrillar matrix in the cortex, with no damage to the cuticle observed.

This study concluded that the process of mummification disfigures facial features, making identification challenging, but commercial shrunken heads retain more defining features compared to ceremonial ones.

This study found that Minoxidil can interfere with hair drug analysis for cocaine by producing peaks that obscure the detection of cocaine and its metabolites in chromatograms.

This study reported that a newly developed UHPLC-MS/MS method detected illegal synthetic hair-growth compounds in 10% of 76 hair-growth products, highlighting the need for ongoing monitoring to protect public health.

This study found that segmental single hair analysis produced ocfentanil concentration profiles similar to those from hair lock analysis, supporting its use in cases with limited samples.

Hair testing is a reliable method for detecting workplace drug use when done with proper sample preparation and confirmation.

This study demonstrates that a single exposure to GHB during a sexual assault can be detected by analyzing hair segments collected about one month after the incident.
