This study found that a short daily photoperiod increased crude protein digestibility, secondary hair follicle activity, and cashmere quality in Inner Mongolia white cashmere goats without harming fiber characteristics.

This study reports that bioactive peptides derived from food proteins may lower serum cholesterol and exhibit antihypertensive and immunostimulating effects, suggesting potential in preventing lifestyle-related diseases.

A fatty acid/protein complex in human hair helps protect it from damage.

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 study found that optimizing proteomic genotyping conditions from single human hair samples significantly improves the detection of genetically variant peptides, enhancing human identification with high precision across different biogeographic backgrounds.

This study found distinct differences in protein expression and wound healing pathways between Acomys cahirinus and Mus musculus, highlighting potential targets for reducing fibrotic response in mammals.

This study identified differentially expressed proteins and pathways potentially involved in wool bending in Zhongwei goats, with specific genes like COL6A1 and CRNN emerging as important candidates in this process.

This study reported that mannan oligosaccharides improved the fur quality, immune response, antioxidant status, and gut microbiota of fur-growing raccoon dogs, suggesting they could potentially replace antibiotics in their diet.

This review discusses human hair follicle development and highlights the potential of creating human in vitro models and skin substitutes with hair follicles, reporting no new clinical results.

In this review, researchers discussed the anti-inflammatory and immunomodulatory properties of metformin and hypothesized that its topical application could benefit those with alopecia areata, given its effects on immune pathways, hair regrowth, and autoimmune disease management.

This study observed that the Raman spectra of human hair cuticle vary with polarization and direction of signal collection, identifying certain spectral bands as markers sensitive to the structural changes in keratin secondary and tertiary structures.

In this study, supplementing low-protein diets with 0.75% methionine maintained growth performance, improved fur quality, enhanced nutrient utilization, and supported intestinal microbiota balance in blue foxes, with significant results on several biochemical parameters and nutrient digestibility observed.

This study found that using composite alginate hydrogels containing Aloe vera, CMC, and tragacanth can improve the encapsulation efficiency and protect pumpkin seed protein hydrolysates from degradation during simulated gastrointestinal digestion, potentially increasing their applicability as functional food components.

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 the outer protein layer of Merino wool is rich in sulfur-containing proteins similar to those found in both sheep wool and human hair.

In this study, researchers identified a cluster of hair-specific keratin-associated protein genes within the 21q22.3 region, revealing a novel transcription mechanism involving TSPEAR/C21orf29 that may bypass typical transcriptional termination sites.

This study highlights the numerous health benefits of chia seeds, including their rich nutrient profile, cardiovascular protection, digestive support, and potential cognitive and athletic performance enhancements, making them a versatile and powerful functional food for modern diets.

This review discusses symptoms and syndromes associated with iron deficiency, with or without anemia, but reports no new clinical findings; the authors highlight the potential influence of intestinal factors on iron absorption.

In this study, Tithonia diversifolia extract was found to improve certain digestive parameters in crossbred sheep but did not enhance growth performance, as the improvements in digestion did not translate into increased body weight or feed conversion.

This study found that postoperative excess weight loss and folic acid levels were independent factors influencing the severity of hair loss after laparoscopic sleeve gastrectomy in obese patients.

This study found that aged tritiated thymidine breaks down and incorporates into cytoplasmic macromolecules, not DNA, suggesting caution in its use.

This review discusses the degenerative effects of anabolic-androgenic steroids on the nervous system and reports no new experimental results, aiming to increase public awareness of their health risks.
