This study found that collagen peptides from Mozambique tilapia significantly promoted hair regrowth and increased the proliferation of hair growth factors in vitro and in vivo, suggesting potential as supplements for hair loss prevention.

This study found that genetically variant peptides from human hair can reliably identify individuals despite differences in age and storage conditions, provided environmental and processing factors are controlled.

GLP-1 RA medications may be linked to hair loss.

This study found that in Liaoning cashmere goats, the BMP4 gene shows increased transcription from the anagen stage to telogen, and higher gene methylation correlates with reduced expression in skin tissue.

This study observed that extracellular ATP is present in Medicago truncatula and correlates with regions of active cell growth, suggesting its integral role in plant development.

This study found that hair shaft keratin proteins can be reliably identified from samples as small as 0.12 cm, suggesting their potential forensic utility with typical casework sample sizes.

This study discusses the proteomic profile associated with hair damage but does not report new experimental findings.

This study identified distinct metabolic differences between PCOS patients and healthy controls, suggesting potential metabolic markers for PCOS prognosis and diagnosis.

This review discusses using human follicular fluid in metabolomic analysis as a diagnostic tool and predictor of success in assisted reproductive technology for PCOS patients, reporting no new results.

The document concludes that there are still unknowns about the effectiveness, risks, and detection of performance-enhancing drugs, and doping remains a challenge.

This case report highlights that a restrictive rice milk diet in a young child led to kwashiorkor with severe malnutrition, skin changes, and developmental regression, which improved with a protein-rich therapeutic diet.

This study reported that among patients aged 19 to 60 who experienced hair loss after COVID-19, a treatment involving a complex drug and peptide lotion led to hair improvement in 92% of cases, with good tolerability and no reported side effects.

A rare pancreatic tumor caused a woman's male-like features, treated successfully with surgery and medication.

This study identified non-structural proteins in preschool children's scalp hair that suggest potential biomarkers for brain development, immune function, and stress response with heritability and age-related differences.

This review evaluates and classifies the non-saponin components of Korean Red Ginseng, emphasizing their combined role with saponins in the plant's bioactivity, but reports no new clinical results.

This study found that TGFbeta is a key pathway causing age-related loss of dermal fat's antimicrobial function, suggesting that targeting TGFBR might help restore skin defense against infections in older age.

Researchers developed a method to identify and measure different animal hair fibers in textiles, successfully distinguishing materials like cashmere from cheaper fibers.

In this study, DHT was found to inhibit hair growth in mice by decreasing IGF-I production in dermal papillae through reduced sensory neuron stimulation.

This study found that systemic ovalbumin–aluminum sensitization followed by cutaneous challenge in mice induced thermal hyperalgesia, increased spinal cord gliosis, and sprouting of nociceptive fibers, along with elevated mast cell and nerve profile densities in the skin compared to controls.

Applying pseudoceramide improved skin and hair health.

This analysis reports that hepatitis B surface protein antigen exposure is associated with an increased risk of alopecia areata.

This study found that the signaling peptide CLE40 and receptor proteins CLV2 and CRN regulate root meristem differentiation through two distinct, antagonistic pathways activated by CLE40 in a dose-dependent manner.

This source provides a review of patents on the use of fish collagen peptides in wound care, highlighting benefits like skin hydration, scar repair, and antiaging, while emphasizing the need for further clinical research to validate these applications.

In a mouse model of infected burns, this study found that treatment with recombinant fusion peptide EK significantly decreased Pseudomonas aeruginosa colony count and improved wound healing rates compared to controls.
