This study describes a capillary GC method for accurately measuring spermidine levels in hair lotions, confirming its precision and specificity for this application.

This study observed that adult male raccoon dogs undergo seasonal moults, with winter fur maturing by the end of November after significant hair growth in spring and autumn.

This article describes the extraction and characterization method for wedelolactone from Eclipta alba but presents no new clinical results.

This study developed a straightforward HPTLC method for detecting nicotine and cotinine in human plasma and urine, concluding that liquid-liquid extraction with methanol: chloroform: ammonia achieved optimal separation and is applicable for forensic analysis of lethal nicotine intoxication.

This study suggests that chest, arm, leg, and beard hair samples may be viable alternatives to scalp hair for monitoring long-term alcohol intake, although body hair is more typically collected from men.

Hair diameter diversity could improve androgenetic alopecia assessment and treatment planning.

This study found that Synechococcus elongatus PCC 11801 responded to increased CO2 concentrations by enhancing photosynthesis and carbon fixation while reducing other metabolic pathways, suggesting its potential for efficient CO2 capture.

This study found that the Hair Mass Index is suitable for quantifying hair loss, but patient self-assessment is the most reliable method for evaluating chemotherapy-induced alopecia in clinical practice.

Glycogen helps E. coli cells divide unevenly and organize their contents.

In this study, Hibiscus rosa-sinesis flower extract was found to contain 0.33% quercetin according to HPTLC analysis and 0.37% according to HPLC. Heavy metals measured were within acceptable limits, supporting the standardization of the plant material for efficacy and safety testing.

This study found that high stress levels among medical students were significantly associated with their performance in the UKMPPD certification exam, with academic stressors being the primary contributors.

This study developed a synchronized fluorescence spectroscopic approach to quantify finasteride and tadalafil in various forms, achieving high accuracy with %recoveries of about 99.62% and 100.19% respectively, and demonstrated superior environmental friendliness compared to previous methods.

People with cleft lip and palate often have respiratory problems.

This review outlines the factors affecting skin greasiness and sebum production, highlighting measurement challenges but reports no new clinical findings; further research may guide sebosuppressive treatments for acne.

This study validated a protocol for inducing surface ectoderm differentiation from human induced pluripotent stem cells and highlighted the role of TGFβ signaling pathways in this process.

This study describes a validated UPLC-MS/MS method for quantifying finasteride in human plasma, demonstrating higher specificity, improved resolution, increased sensitivity, and faster analysis times compared to conventional HPLC-MS/MS methods.

This study developed and validated a sensitive LC-MS/MS method for quantifying tamsulosin in human serum, achieving high analyte recovery and demonstrating applicability in clinical research for benign prostatic hyperplasia.

In this study, an LC/MS/MS method was successfully developed to determine finasteride concentrations and study its pharmacokinetics in healthy male Chinese volunteers.

This review discusses strategies for developing semi-solid topical generic products to match the quality of reference-listed drugs, using concepts like quality by design and reverse-engineering, but reports no new results.

This study introduced a new classification system for distinguishing between anagen VI and early catagen stages in human hair follicle organ culture, using it to confirm eflornithine's ability to induce premature catagen.

This study developed and validated a high-resolution mass spectrometry method to screen for prohibited substances and analyze six endogenous steroids in urine according to World Antidoping Agency requirements, demonstrating its effectiveness for antidoping analysis.

This study found that keloid tissues exhibit epithelial-mesenchymal transition-related changes and alterations in gene expression, implicating these processes in the pathogenesis of keloids.

This study found that basement membrane components and structures in mouse hair follicles are highly specialized for specific inter-tissue interactions, with laminin α5 playing a crucial role in hair cycle regulation and anchoring.

This review discusses the unmet supportive care needs of men and women experiencing chemotherapy-induced alopecia and reports no new results, urging healthcare providers to tailor interventions to individual patient needs.

This study observed that the growth cycle of cashmere in Inner Mongolian cashmere goats consists of three phases, with genes KAP3–1, KRTAP 8–1, and KRTAP 24–1 closely correlating with this cycle.

This study suggests that the T allele of the SNP rs2476601 in the PTPN22 gene may increase the risk of alopecia areata, although further studies are necessary to validate this finding across different populations.

This study found that non-pigmented hair follicles have significantly lower expression of nucleotide excision repair genes, which may be associated with reduced melanin production capacity in these follicles.

This study found significant differences in hair traits among scalp, axillary, and pubic hair in Bengalee Hindu caste females, suggesting these variations could aid in forensic personal identification.

Iron deficiency might be linked to hair loss, but more research is needed.

This study found that the expression levels of nucleolin, nucleophosmin, and UBTF genes were lower in normal sites compared to hair loss sites in males with alopecia.
