This review discusses the potential role of vitamin D deficiency in cardiovascular and renal diseases and suggests that supplemental vitamin D could benefit cardiovascular outcomes, especially in African American and postmenopausal women; it reports no new clinical findings.

This study used nanoscale secondary ion mass spectrometry to locate where calcium and copper are concentrated in colored hair, finding these metals particularly in the cuticle's sulfur-rich regions.

In this study, treatment with aqueous KCN selectively converted disulfide bonds to monosulfide crosslinks in hair, leading to changes in microstructural properties and rubberlike elasticity under specific laboratory conditions.

This study found that a shampoo containing quaternized wheat protein hydrolysate can effectively improve hair recovery by smoothing and compacting damaged hair surfaces, thanks to modifications that enhance protein adherence and disulfide bond formation at pH levels typical in hair care products.

This study found that thioglycolic acid molecules in hair treatments are primarily located in intrafibrillar unordered areas, where they redistribute disulfide bonds.

This study found that coconut oil impedes hair hydration more effectively than soybean oil by penetrating deeper, and suggested a new model for intermediate filament assembly in hair.

This study found that Caucasian hair is destroyed more easily than Asian hair when stretched, as indicated by changes in secondary structure, disulfide bond breakage, and physical disintegration.

This study found that the alkaline degradation process of hair keratin using nucleophilic reagents led to different proportions of reaction products compared to wool, particularly more lanthionine and lysinoalanine residues.

This study discusses treatment approaches for refractory Asherman syndrome, highlighting the potential role of CD133+ bone marrow-derived stem cells in conjunction with hysteroscopy for endometrial regeneration and improved pregnancy outcomes.

This review discusses the role of astrotactins in development and their genetic mutations' links to a variety of human diseases, but reports no new clinical results.

This review discusses advancements in stem cell therapy for cutaneous radiation syndrome, highlighting the potential of various stem cell sources to improve wound healing and reduce symptoms, but reports no new clinical results.

This study found that involucrin likely plays a key role in forming the cornified material of the medulla and inner root sheath of human hair, contributing to its mechanical strength.

This model study describes how interactions between hair keratin and various materials alter hair's physical and mechanical properties by affecting noncovalent bonds.

This article reviews the complex structure and molecular composition of hair keratins, highlighting their self-assembly process and implications for keratin extraction techniques, but reports no new experimental results.

This article reviews gaps in our understanding of molecular events in hair follicle growth, focusing on keratin synthesis and protein oxidation, but reports no new findings.

In this in-vitro study, researchers found that shampoo-induced coacervates structurally resemble cationic polymers and contain anionic surfactants that may stimulate the scalp upon exposure to water.

This review discusses the use of zebrafish larvae as an alternative model for studying ototoxicity, facilitating large-scale screening for otoprotective compounds, but reports no new clinical results.

This review discusses the use of Tisseel for stabilizing particulate grafts and reports no new clinical results; the authors emphasize the need for further controlled trials.

This review discusses the protective and reparative properties of chitin nanofibrils on hair structure and reports no clinical results; the authors suggest chitin-based products may aid in hair regrowth.

This study found that the weak tensile strength of pili torti hair may result from loose keratin intermediate filaments due to abnormalities in disulfide bonds.

This study proposed a network model for the cross-linked structure of keratin-associated proteins in hair and wool fibers, suggesting notable differences between the two, potentially affecting hair fiber elasticity.

In this study, the authors concluded that a hydrolyzed eggwhite protein treatment promoted the reconnection of disulfide bonds in excessively bleached hair, after reduction and oxidation processes in permanent waving.

This study observed that bleaching brown human hair with persulfate salts and hydrogen peroxide induced significant conformational changes in keratin, particularly affecting disulfide bridges and oxidized sulfur species, which may inform the development of hair restorative treatments.

In this study, combined treatment with transglutaminase and keratin significantly repaired damaged hair by improving its structural properties, reducing swelling, and enhancing crosslink activities, as evidenced by microscopy and spectroscopy analyses.

This study found that adding dithiodiglycolic acid to the hair straightening process decreased chemical damage and preserved the structural integrity of the hair matrix compared to using thioglycolic acid alone.

This study found that using cationic and non-ionic polymers during alkaline hair relaxer treatments may help strengthen hair and control swelling, potentially reducing damage.

This study found that L-cystine-modified rabbit hair fibers had improved dye adsorption and spinnability, due to changes in secondary structure and surface characteristics.

This article explores the origins and differences between human and animal faces, emphasizing the face's role in communication and its relevance to plastic surgery, but presents no new research findings.

This study verified that a new straightening process involving a flat iron, ammonium thioglycolate, and hydrogen peroxide may permanently straighten wavy hair by eliminating disulfide bond distortions.

In this study, the use of internal wool lipid liposomes was shown to improve the lipid composition and increase the resistance to breaking in both untreated and chemically treated hair fibers.
