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 developed a sensitive method to precisely determine hair lipid composition, demonstrating specific lipid changes from the root to the tip in untreated hair fibers from two women.

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 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 study describes an efficient gas chromatography-mass spectrometry method for detecting estrone and 17 beta-estradiol concentrations in hair, finding differing levels in male and female samples.

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 found that using hair steroid profiling, dutasteride treatment led to reduced dihydrotestosterone levels and DHT/testosterone ratio in patients with male-pattern baldness.

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 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 evaluated the antimicrobial activity of Albizia saponaria stem bark against microorganisms causing dandruff and fungal alopecia. It found that the hexane fraction exhibited potent antifungal effects comparable to ketoconazole, highlighting its potential as a natural therapeutic for dandruff.

This study found that a rosemary extract hair tonic at concentrations up to 15% effectively promotes hair growth in male Wistar rats, achieving longer and thicker hair compared to minoxidil 2%, and causing fewer side effects.

This study characterized bioactive compounds in extracts from six Kalimantan herbal plants, confirming traditional medicinal uses with findings such as triterpenoids and several potent compounds with antimicrobial and cardiovascular benefits, laying groundwork for potential therapeutic applications and conservation efforts.

In this study, GC/MS analysis revealed variability in the quality of Syrian herbal formulations for BPH, with variations in tocopherol content, presence of parabens, and shortages of certain phytosterols.

In this study, a herbal oil formulation combining Hibiscus rosa-sinensis, Jasminum officinale, and Ficus benghalensis showed potential in reducing dandruff and promoting hair growth in affected individuals.

This study found that unsaturated fatty acids are more abundant in the cortex of human hair than on its surface, and steryl glycoside-like lipids may help bind the cuticle to the cortex.

This study found that volatile compounds from Bacillus subtilis strain WM13-24 improved root development in Arabidopsis by influencing auxin signaling.

This study investigated the therapeutic potential of phytochemicals from Phyla nodiflora, identifying 50 bioactive compounds through GC-MS analysis. Among them, n-hexadecanoic acid, stigmasterol, and beta-sitosterol showed promise in molecular docking studies as drug candidates for diabetes, alopecia, cancer, and anti-diuresis.

This review examines recent advancements in analytical techniques used to quantify dutasteride, a medication for enlarged prostate, in various biological samples and its commercial forms, emphasizing methods such as HPTLC, GC-MS, and HPLC.

This study identified various phytochemicals and compounds in Eclipta prostrata leaves using qualitative tests, FTIR, and GC-MS analysis, highlighting the presence of phytol and squalene among others.

This study found that water-soluble beehive extract exhibited anxiolytic, antidepressant, and anti-inflammatory effects in animal models.

This study developed a faster method to analyze fatty acid ethyl esters in human hair, potentially distinguishing alcohol consumption levels more efficiently.

In this study, researchers used gas chromatography–mass spectrometry to analyze agarwood from Laos and Thailand, identifying key volatile compounds also found in five other regions, and highlighted cytokine-regulated anti-inflammatory activity as a significant biological mechanism, suggesting potential for pharmaceutical and cosmetic applications.

This study investigated the phytochemicals in Phyla nodiflora leaf extracts and identified n-Hexadecanoic acid, stigmasterol, and beta-sitosterol as promising drug candidates for diabetes, alopecia, cancer, and anti-diuresis, advocating further research into these compounds.

Infected shallots have more diverse metabolites, with certain compounds indicating resistance to Fusarium disease.

This study found that methanol extract from Anisomeles indica has significant antidepressant and antidiarrheal effects in animal models and notable anti-inflammatory activity in vitro.

This study reported that both Sterculia villosa bark and Vernonia patula plant extracts showed concentration-dependent antioxidant activities, with Vernonia patula demonstrating a stronger effect.

This study found that methanolic extract of Eclipta alba leaves exhibited strong antibacterial effects against certain pathogens including methicillin-resistant Staphylococcus aureus, but it showed no activity against Mycobacterium tuberculosis, including drug-resistant strains.

This study observed that Citrus limon essential oil demonstrated significant anticancer activity against an MCF-7 breast cancer cell line, suggesting its potential as a complementary cancer treatment.

The document concludes that inflammation markers can be used in diabetes, vitamin D3 affects immune pathways, hyperthyroidism changes hormone levels, androgen levels help diagnose Adrenocortical Carcinoma, erectile dysfunction is linked to diabetes, hypogonadism is common in HIV-infected males, and hormones can be biomarkers for various conditions.
