This study suggests that hair analysis could serve as a diagnostic tool for detecting calcium channel activity, which influences hair calcium levels and may indicate calcium deficiency or related disease states.

This study reported the development of a workflow that combines SIMS and X-ray elemental mapping techniques for multimodal imaging at the single cell level, successfully applied to visualize elements, metals, and lipids in porcine skin without loss or delocalization.

This study describes a modified reduction-osmication method for staining human scalp hair that improves reagent penetration and visualization of hair cortex features using transmission electron microscopy.

This article examines the emergence of predictive analytics with big data and concludes that Foucault's concept of biopower is now a hybrid involving various technologies to monitor and model behavior and risk.

This review reports on the use of nails as an alternative biological matrix to hair for assessing long-term drug consumption, emphasizing that while there are clear differences between nail and hair samples, more standardized research is necessary for definitive conclusions.

This study developed a quantitative measure for scoring hair surface damage from SEM images and found it accurately classified hair damage caused by explosive blasts, similar to an existing classification system.

The researchers found that using hair analysis to detect past use of cannabinoids or amphetamines in individuals with psychosis was limited by individual variations in hair growth rates, affecting the method's reliability.

This study reports that hair damage from bleaching is associated with the oxidative cleavage of fatty acid thioester bonds, detectable by measuring the decrease in mass spectrometry peak at m / z 76.

Quickly fix tissue in formalin after excision to preserve it.

This study using an apertureless scanning near-field optical microscope found that dye restricted to hair's periphery remains mainly on the surface and in the endocuticle.

Three new techniques simplify and improve the preparation of tissue samples for skin cancer surgery.

This review found an increasing trend in research on sperm DNA fragmentation over the past 20 years, especially focusing on lifestyle factors, asthenozoospermia, and varicocele, with the TUNEL technique as a predominant method.

This study found that among bodybuilder-intended drugs from the black market, 33.8% of labeled products and 52.5% of steroidal oily solutions contained ingredients not matching their labels.

This article discusses using hair analysis to monitor drug use but does not present new research findings.

Hair movement can indicate hair quality and health.

This study found that electron and proton microprobe analysis can reveal differences in element distribution within human hair and epidermis, although no significant water content differences were noted between atopic eczema and normal skin.

The method effectively analyzes human hair proteins, especially nonfilamentous ones.

This study found that lead accumulated in the hair shafts of individuals exposed to mining environments, while iron, copper, and zinc levels remained stable, highlighting the significance of SRXRF micro-analysis for environmental health research.

This study provides conclusive evidence of exogenous calcium fatty acid deposits forming between the cuticle layers in hair, affecting its optical and mechanical properties.

This study used rapid-freezing immunocytochemistry to successfully map the ultrastructural localization of hair keratins in human scalp hair, primarily finding them in macrofibrils in the cortex and endocuticle.

This article reviews the steps and methods involved in preparing skin tissues for three-dimensional volumetric imaging, highlighting its potential to provide detailed insights into skin structure not possible with traditional 2D histology, but reports no new findings.

This study highlights confocal microscopy as a promising, minimally invasive tool for assessing hair morphology and internal structures, making it valuable for cosmetic hair assessments.

Hair movement can indicate hair quality and health.

This review examines physical methods like electron paramagnetic resonance spectroscopy, Raman spectroscopy, and differential scanning calorimetry, highlighting their complementary capabilities in analyzing biomolecular structures and mycobacterial interactions with reactive oxygen species and antioxidants.

This study found that Quantitative Mass Spectrometry Imaging offers precise localization and quantification of active compounds in skin tissues, demonstrating benefits over traditional LC-MS in drug penetration studies.

This study found that a high-fat diet exacerbates hair loss in female mice by increasing oxidative stress and androgen signaling in the skin, and that treatments with antioxidants or antiandrogens may help mitigate this effect.
