In this study, the inclusion of a feedstuff high in energy along with soybean meal enhanced body condition, body mass index, and reproductive performance in sheep fed low-protein forage.

This article discusses the composition and function of the dermal papilla in hair follicles, focusing on its role in hair shaft generation and suggesting that cell loss in this area may contribute to hair loss.

This study found that Naked trait mice exhibit a decrease in certain low-molecular-weight proteins in their hair, which contain high levels of glycine and tyrosine, compared to normal mice.

This study found that straight crimp mutant wool differs from crimpy wool in the layout of cortical cells and the relative proportions of keratin and keratin-associated proteins.

This study found that cashmere has a significantly smaller mean fiber diameter compared to sheep and goat wool, and identified key proteins that may influence this difference.

This study analyzed the cornified envelope of epidermal proteins, finding keratins dominate, which may help explain the minimal impact of deleting genes for single envelope components in congenital ichthyosis.

This review discusses the history and composition of permanent hair waving products for different hair types and reports no new research findings.

This study suggests that analyzing the composition and modifications of hair proteins may provide new biomarkers for assessing hair health, diseases, and aging.

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 study found that hair proteome profiling and genetically variant peptide identification in hairs remained effective after an explosive blast, indicating potential for forensic human identification despite damage.

In laboratory tests, this study found that a novel natural composition targeting 5-alpha reductase and inflammatory pathways reduced disease-related markers in androgenetic alopecia and benign prostatic hyperplasia more effectively than finasteride.

This study found that fish oil supplementation in male Wistar albino rats helped maintain hair shaft structure and improved amino acid composition, while reducing harmful protein compounds associated with diabetes and hypercholesterolemia.

This study found that improved protein extraction methods enhanced the resolution of hair proteins on gels, but differences in protein abundance between curly and straight Japanese women’s hair were minimal and unlikely to affect hair structure.

This study found that a laboratory model using nude mice can produce human hair follicles with amino acid compositions resembling both normal and trichothiodystrophy-affected human scalp hair over extended periods.

This study found that while molecular hair structures were nearly identical across individuals, genetic factors seem to influence specific lipid compositions, as seen in identical-patterned hair from parent-child pairs and identical twins, but not fraternal twins.

This study found that zinc is primarily located in the tails of mature rat sperm, associated with -S-S-bonded structures, and suggests a possible similarity in zinc interactions between sperm keratin and hair proteins.

This study found that hair samples from children with kwashiorkor or marasmic kwashiorkor had about 20% less cystine compared to one child with adequate protein nutrition, suggesting the need for further research.

This review discusses the diversity of keratins and keratin-associated proteins in wool and hair, noting significant variation in their families, with no new results reported; the authors detail known protein structures without experimental findings.

Keratin proteins in epithelial cells are dynamic and crucial for cell processes and disease understanding.

This study found that permanent wave lotion I extracts proteins from human hair, with molecular weights ranging from 5,000 to 65,000, which may elucidate hair damage mechanisms.

This Mendelian randomization study reports that lifelong increased free testosterone in males was associated with improved bone mineral density and body composition but increased risks of prostate cancer, hypertension, and several other conditions.

In this study, grade 5 learners preferred Edamame snacks over their usual sweet-flavored snacks, and different roasting methods did not significantly change the nutritional quality of Edamame beans.

In this study, researchers found that the absence of type I or type II keratins in mice leads to severe skin barrier defects, highlighting keratins' crucial role in epidermal structure and function.

This study reported advances in identifying low-abundance proteins in wool by using fractionation techniques to reduce the dominance of intermediate filament proteins, improving the understanding of the wool proteome.

This study found that keratin-associated proteins form part of the developing exocuticle and a-layer in hair fiber cuticle cells, while cornified envelope proteins were absent.

This study found that pepsin digestion was more effective than trypsin at identifying keratin-associated proteins in human hair shafts and confirmed that trypsin introduced a bias in the analysis of protein composition that pepsin can correct.

This review integrated findings on the nutritional, pharmacological, and techno-functional properties of Leucaena seeds, highlighting their potential benefits and challenges for human nutrition, particularly due to the presence of the antinutrient mimosine, which can cause adverse effects.

This study found that inactivating CerS4 in mice led to hair follicle stem cell exhaustion and hair loss, indicating its role in regulating hair regeneration through ceramide composition and signaling pathways.

This study reported the first known occurrence of citrulline in an animal protein, specifically in the fibrous protein of hair follicle inner root sheaths.

This study found that, despite the unchanged total level of 18-MEA, deletion of the Sox21 gene disrupts its attachment to the hair cuticle, increases cholesterol sulphate levels, and differentially affects ceramide composition.
