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.

Hair can show daily calcium changes, linked to body calcium levels and influenced by hormones, and can help assess calcium metabolism issues.

The method effectively maps lead and zinc in hair, aiding understanding of heavy metal exposure risks.

This study found that a modest increase in dietary zinc over six months resulted in a detectable increase in sulfur and zinc counts in individual hairs, suggesting a non-invasive method to monitor zinc intake effects.

This study developed a non-destructive X-ray fluorescence technique to quantitatively analyze elemental content in human hair and constructed a database of element concentrations in healthy Swedish, Caucasian individuals.

This study suggests that hair analysis detecting trace elements like copper and iron may help in screening for diseases such as hepatocellular carcinoma and osteoporosis, due to altered element concentrations in patients.

This study found that women with diffuse alopecia exhibited deficiencies in several trace elements, including sulfur, iron, and potassium, while men showed deficiencies in calcium, sulfur, and zinc.

This study found that hair analysis may be useful in early breast cancer detection by identifying distinct calcium and strontium concentration patterns before and during cancer development.

This study identified two types of calcium in human scalp hair, with one type highly variable between individuals, potentially impacting the analysis of environmental and medical factors related to hair calcium.

In this study, human scalp hair grafted onto nude mice accurately reflected methyl mercury exposure, demonstrating its potential as a research model for monitoring mercury incorporation into human hair.

Hair grows like a crystal at a solid-liquid interface without cell division.

PMS nanoparticles improve damaged hair by protecting and restoring its surface and color.

This review examines the effects of various factors on the molecular and nanostructural ordering of human hair, highlighting its potential as a diagnostic material for environmental and public health monitoring, but reports no new experimental results.

This study reports that different animal species exhibit distinct hair scale patterns and elemental compositions, which can aid forensic investigations in identifying animal hair.

This study used X-ray fluorescence to analyze elemental and heavy metal contents in Senegalese powdered milk, finding potential safety concerns with excessive calcium in certain samples and significantly high potassium levels in one, suggesting ongoing monitoring is crucial for consumer safety.

In this study, powdered milk samples from Senegal showed varying levels of heavy metals, with some exceeding acceptable maximum levels for calcium, potassium, and phosphorus, indicating potential safety concerns.

This review discusses arsenic trioxide therapy in acute promyelocytic leukemia and introduces a novel method using hair analysis to monitor arsenic exposure and correlate it with treatment timing, but reports no new clinical results.

This study suggests that the presence of vellus hairs and empty spaces in prepubertal scalps may reflect a natural resting phase of hair growth rather than indicating early androgenetic alopecia.

This study is the first to document alopecia in Guadalupe fur seals in the Northeast Pacific Ocean, finding that it may result from nutritional stress due to higher sea surface temperatures.

This study found that the dimethyl-β-cyclodextrin inclusion system significantly improved the solubility and bioavailability of finasteride compared to the drug alone, enhancing its absorption rate.

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 review discusses the potential medicinal properties and pharmacokinetic features of nettle compounds ursolic acid and quercetin, highlighting quercetin as a promising candidate for antioxidant and anti-aging effects, but reports no new clinical results.

This study found that while yak belly hair is chemically similar to human hair, its higher porosity and lower mechanical strength limit its usefulness as a substitute in hair dye development.

This study observed that two patients treated with interferon α-2b and ribavirin for chronic hepatitis C experienced complete and reversible straightening of their natural curly hair, which recurred with treatment resumption.

This study found that a microneedle patch using manganese thiophosphite showed greater hair regrowth potential compared to minoxidil, even with less frequent application, for treating androgenetic alopecia.

This study found that using human hair follicle dermal papilla cells, 53BP1 focus counting can estimate radiation doses from 50 mGy after 5 hours, and focus size analysis refines dose estimation for doses ≥ 500 mGy up to 96 hours.

In this study, researchers found that ligand homodimerization controls the receptor binding specificity of the FGF9 subfamily, preventing off-target activation of FGFR "b" isoforms.

This report describes a study of estuarine bed-sediment quality in New Jersey and New York post-Hurricane Sandy, focusing on contamination extent and potential long-term impacts, with no new findings included.

This study discovered a new region in the hair cortex where intermediate filaments are both aligned with the hair's axis and orientationally ordered, influenced by the cuticle boundary.

This study shows that environmental contamination affects mummy hair, suggesting that using it to assess ancient people's health or nutrition should be approached cautiously.
