Feathers become harder as they develop due to a change in keratin type.

This study examined feather follicle density in yellow-feathered broilers, finding that back follicle density was significantly higher than leg density and negatively correlated with various body weight measures; it also identified genetic markers and candidate genes, such as SERPINF1, associated with follicle density variations.

In this study, hemp seed-derived exosomes (E40) showed potential for counteracting DHT-induced inhibition of feather follicle development in chicken embryos by modulating critical signaling pathways, suggesting a therapeutic approach for alopecia.

This review discusses the potential of using Arabidopsis thaliana to express fusion protein TDP1-KGF-2, aiming to enhance the transdermal delivery of KGF-2 for hair growth applications, despite current challenges with production costs and efficacy.

In this study, researchers investigated the genetic basis of the feathered foot trait in Guangxi native chickens and found that the gene TBX5 plays a critical role, suggesting it affects feather formation by regulating the proliferation and migration of dermal fibroblasts.

This study documented 55 weed species at Daffodil International University, highlighting their ecological and cultural importance, with many species having recognized ethnobotanical uses such as hair growth and skin disorder treatments.

This study found that the Arabidopsis cation chloride cotransporter (CCC1) is crucial for regulating pH and processes in the trans-Golgi-network/early endosome, impacting plant growth and stress responses.

This study tested a natural hair dye made from papaya seed extract, celery leaf, and avocado, finding color change in animal hair but also noting tissue changes like hyperkeratosis.

This study found that Peperomia pellucida extract may promote hair growth, improve male libido and fertility, and support renal cell health.

This study found that ethanolic plant extract of Peperomia pellucida increased hair length in rabbits in a dose-dependent manner but did not significantly affect hair mass compared to controls.

In this study, disruptions in phospholipase A2 activity in Arabidopsis thaliana significantly impaired the plasma membrane localization of PIN proteins, affecting auxin transport and root development.

This study found that oral broiler meat extract increased body weight, visceral fat mass, and the number of hair follicles in young male Wistar rats.

This study found that under optimized extraction conditions, the Gleditschia fera fruit extract contained a high level of saponins and demonstrated notable antioxidant activity.

This study in a rat model found that dietary rehabilitation with a high protein diet reversed symptoms of kwashiorkor, suggesting a role for free radicals in its development.

This study reports that the DMI3 gene, essential for nodule formation in legume-rhizobial symbiosis, encodes a calcium/calmodulin-dependent protein kinase, highlighting its role in multiple plant symbioses.

This study suggested that an herbal shampoo containing Piper betle and Psidium guajava leaves extract may promote hair growth due to its antioxidant properties and showed stability for two months.

This study assessed the antioxidant properties and contents of carotenoids and chlorophylls in 10 plant oils, finding fenugreek seed oil to be highest in carotenoids and pomegranate oil most active against free radicals, highlighting their potential as natural materials with antioxidant benefits.

This study suggests that the oil extracted from Citrullus colocynthis seeds may be suitable for edible use and exhibits antimicrobial properties against several bacterial and fungal strains.

In this study, researchers showed that the CAP1 gene regulates root hair growth in plants by modulating cytoplasmic ammonium levels and maintaining calcium gradients, highlighting its role in ammonium homeostasis.

This study created a detailed atlas of endogenous peptides across 13 maize tissues during various developmental phases, revealing a complex regulatory network where peptide abundance doesn't always align with their source proteins, signaling unique roles in maize development.

This study found that endophytic bacteria isolated from Leea indica leaves showed high antioxidant activity, suggesting they could be a novel source of natural antioxidants.

This study found that overexpressing the CLE peptide SlCLE10 in tomatoes increased root hair length and improved drought tolerance, suggesting its potential for enhancing crop resilience to osmotic stress.

This study identified novel endophytic actinobacteria from the Citrullus colocynthis plant with antibacterial properties, suggesting potential for new antibiotic development against multi-drug-resistant bacteria.

This review examines the potential of Cucurbitaceae seeds, such as those from watermelon, melon, and pumpkin, as sustainable and innovative ingredients in cosmetics, highlighting their rich bioactive composition and benefits for skin and hair, despite challenges like environmental instability and low permeability.

This study suggests that inactivation of β-catenin is necessary for chick retina regeneration, as it allows cells to enter the cell cycle during injury and promotes regeneration without needing FGF2.

In a rabbit study, flaxseed oil applied topically significantly increased hair width, while flaxseed ingestion also had a positive effect, but neither method improved hair length or weight.

In this study, ground flaxseed intake was associated with increased hair growth and improved metabolic markers in rabbits, but the mechanisms and optimal usage remain to be determined.

This study suggests that a topical emulsion containing Camellia sinensis and Allium cepa extracts may show promise for treating alopecia areata in Wistar rats.

This study found that ethanol-based extracts of Allium sativum and Trigonella foenum-graecum exhibited strong 5α-reductase inhibitory activity, suggesting potential for managing testosterone-induced diseases like androgenetic alopecia.

This study quantitatively determined zinc concentrations in several leafy vegetables from Tudun Wada-Makera, finding that Amaranthus tricolor had the highest zinc concentration and Brassica olaracea the lowest.
