This study found that the dynamic characteristics of both cerebrovascular carbon dioxide reactivity and central respiratory chemoreflex decrease in the high frequency range and are not modified by exercise.

This article describes a newly developed portable instrument for measuring hair density, emphasizing its significance in advancing hair restoration techniques.

This study quantified the effects of chemical treatments like oxidative bleaching and hair relaxing on the movement characteristics of hair strands using a novel high-speed recording method.

In this study, the average force required to pluck hair was significantly lower in malnourished adults, especially those with kwashiorkor, compared to well-nourished individuals.

Hair movement can indicate hair quality and health.

Adjusting hair dryer settings improves drying efficiency and keeps hair healthy.

This study used a multi-point tension test method to evaluate hair damage over time and found it useful for assessing the effects of cosmetics and metal content on hair strength.

Antisense oligonucleotides show promise for treating Myotonic Dystrophy type I.

This study developed a follicular automaton model that simulates human hair cycle dynamics and can replicate hair pattern changes associated with diffuse or androgenetic alopecia.

The study found that the break force of human hair significantly depends on hair diameter and strain, but not on age, gender, use of hair dye, or drugs.

This study presents a follicular automaton model that simulates human hair cycle dynamics and can reproduce hair patterns similar to diffuse or androgenetic alopecia by incorporating spatially heterogeneous parameters and follicle miniaturization.

This study found that the cross-section trichometer is a promising tool for measuring hair mass index with high reproducibility, suggesting potential clinical and research applications.

This study found that due to variability in measurements, hair pluckability is not a reliable indicator of adult nutritional status, although it may hold potential in certain emergency situations if improved for consistency.

This study found that real-time 2-D Doppler echo of intracardiac blood flow helps evaluate myocardial infarction severity, with persistent late systolic inflow indicating worse left ventricular function.

This paper details a method for measuring testosterone metabolism into seven androgens using digital autoradiography, which offers high sensitivity and reduces the need for radioactive materials.

This study found that torsional measurements can effectively distinguish the effects of hair care products on the cuticle versus the cortex of hair fibers, unlike tensile measurements.

In this thesis, researchers explored ways to enhance the management of myotonic dystrophy type 1 by investigating the genetic inheritance patterns, especially small-sized repeat expansions, and assessing cardiac care, energy expenditure, and body composition in affected individuals.

This study developed a method that combines image-based and simulation techniques to improve the reconstruction of hair dynamics from multi-view videos, enabling accurate hair motion representation and animation.

This study demonstrated that lactate dehydrogenase activity is notably high in quiescent hair follicle stem cells within mouse skin using a specific enzymatic activity assay.

This study developed a multiscale model to understand human hair fiber mechanics and found that the yield stress decreases linearly with temperature, supported by both simulations and experimental stretching of hair fibers.

Atomic Force Microscopy is a more accurate way to assess hair damage and the effect of cosmetic treatments.

This review discusses the free hormone hypothesis for measuring "free" testosterone and critiques its theoretical basis and clinical application, noting it lacks critical empirical testing and has inconsistent utility in assessing androgen status.

In this hospital-based observational study involving 30 participants, researchers found no statistically significant difference in the force needed to pluck anagen versus telogen hair in the frontal and occipital scalp regions of women with female pattern hair loss.

This Viewpoint discusses the utility of dermoscope in routine practice and how familiarity with dynamic vs static trichoscopy may address its limitations, but it reports no new clinical findings.

This study suggests hair diameter may indicate protein status in children if the sampling location on the head is controlled, noting inconsistencies in past research.

This study developed a novel method to simultaneously measure finasteride, dutasteride, and related biomarkers in serum, finding that both drugs lowered DHT levels while increasing substrate concentrations.

This study reported high analytical performance of an RMP for DHT quantification, with the ability to differentiate between 5α-DHT and 5β-DHT isomers, making it suitable for routine assay standardization and clinical sample evaluation.

In this case series, oral administration of zinc improved or cured hair loss in patients with zinc deficiency-related telogen effluvium.

This study suggests that analyzing hair samples with a liquid chromatography-mass spectrometric assay may offer a reliable method to measure average quarterly vitamin D levels, potentially complementing blood tests.

This study found a perfect correlation between laser Doppler velocimetry measurements of scalp blood perfusion after minoxidil application and sulfotransferase enzyme activity in hair follicles, indicating a potential non-invasive test to predict minoxidil response in female pattern hair loss.
