In this study, researchers developed microparticle-embedded gas-propelled microneedles that showed higher drug loading and transdermal delivery efficiency compared to traditional microneedles.

This study found that using headspace capillary gas chromatography effectively determined the levels of residual organic solvents, including chloroform and dichloromethane, in finasteride with good separation and detection limits.

In this study, solid lipid microparticles loaded with lidocaine hydrochloride were developed to effectively deliver pain relief and antimicrobial benefits for wound management, demonstrated by testing with bioengineered skin substitutes and showing effectiveness against common wound-infecting bacteria.

This study suggests that the outermost hair cuticle surface is rich in 18-methyleicosanic acid (18-MEA), supporting previous findings of its multilayer lipid and protein structure.

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.

This study suggests that while hair analysis using GC-MS is a sensitive method for detecting cocaine ingestion, it may not reliably indicate the amount, timing, or duration of drug use due to interindividual variability and multiple incorporation mechanisms.

This study used gas chromatography-mass spectrometry to simultaneously quantify androstenedione, dihydrotestosterone, dehydroepiandrosterone, testosterone, androsterone, etiocholanolone, progesterone, and pregnenolone in human hair, detecting differences in steroid concentrations between male and female samples.

This study concluded that steroid deficiencies were significantly more severe in men with panhypopituitarism than in those with isolated gonadotropin deficiency.

This review examines hair removal practices prior to genital gender affirming surgery, noting current variations and offering a practical laser hair removal approach, but reports no new clinical results.

This study observed that prolonged water or soil exposure can lead to significant reductions in drug levels in bleached and natural hair samples.

This study found that concentrations of THCCOOH in hair do not correlate well with self-reported cannabis use due to inaccuracies in the self-reported data, but it provides preliminary insights into usage patterns.

This study analyzed patients with X-linked dominant chondrodysplasia punctata and identified novel mutations in the emopamil-binding protein gene, highlighting the need for genetic testing alongside biochemical analysis for accurate diagnosis.

Accurate method measures finasteride levels in human plasma using gas chromatography-mass spectrometry.

This study found that the yeast androgen screen (YAS) could detect the activity of methyltestosterone in urine for a longer period than classical GC/MS, potentially identifying long-lasting metabolites.

This study reports that hair analysis could potentially monitor metformin use in diabetic patients, suggesting a possible correlation between daily dose and concentration in dark hair but not in light hair.

This review discusses the analysis of pharmaceutical relics from prehistoric times to the twentieth century and emphasizes the need for a multifaceted approach, but it presents no new experimental results.

This study found that among MtF transgender individuals, those with early-onset gender dysphoria exhibited differences in age at surgery, sexual orientation, and sexual activity compared to those with later-onset dysphoria.

This review examines existing evidence on the efficacy and safety of gender affirming hormone therapy in relation to Gender Affirmation Surgery, but reports no new clinical results.

This study found that hydro-alcoholic Eclipta alba extract may have anticancer and multidrug resistance-reversal effects in animal models, suggesting potential as an adjunctive agent in tumor chemotherapy.

This study observed that the isotope-dilution GC-MS technique can assess 5α-reductase activity more effectively than conventional methods in rat liver S9 fractions, particularly at low testosterone levels.

This study suggests that analyzing hair care product components left on hair using GC and GC-MS may provide a more objective forensic comparison than morphological examination.

This research observed that a silver nanoparticle-loaded polydopamine/polyethyleneimine-coated bacterial cellulose dressing effectively inhibited S. aureus infections, reduced inflammation, and promoted wound healing compared with untreated cellulose, demonstrating its potential for treating infected wounds.

This study analyzed watercress oil and confirmed its phytochemical profile, UV absorption properties, and potential efficacy for hair growth, supporting traditional hot oil applications.

This study found that bioconjugating 16-methylheptadecanoic acid to damaged human hair can mimic the protective function of the original 18-methyleicosanoic acid, effectively restoring both the hair's external structural integrity and its internal moisture balance.

This study found that diagnosing non-classical 3 beta-hydroxysteroid dehydrogenase deficiency solely based on elevated serum or urinary 5-ene-steroids may not be reliable.

This study found that early diagnosis using gas chromatography/mass spectrometry and appropriate long-term treatment are crucial for improving outcomes in patients with methylmalonic acidemia.

This study found that integrating graphene oxide into a biodegradable composite made from discarded hair keratin enhanced its structural properties, biodegradability, and gas barrier performance, indicating potential use as an eco-friendly packaging material.

This study developed a validated gas chromatography–tandem mass spectrometry assay to assess sex steroid hormones in cerebrospinal fluid, finding substantial levels of DHEA, androstenedione, and testosterone, with strong correlations to serum levels, providing insight into sex steroid dynamics in the human CNS.

The researchers reported that the novel MBTPS2 variant p.Glu172Asp found in a male proband is likely pathogenic, consistent with osteogenesis imperfecta symptoms and molecular signatures, including disrupted fatty acid metabolism and collagen production.
