The 3D structure of a key hair protein was modeled, revealing specific helical structures and stabilization features.

Human hair has different protein structures in its cuticle and cortex.

Corneous beta-proteins evolved uniquely in reptiles and birds, forming scales, claws, beaks, and feathers.

Infrared and Raman imaging can non-destructively analyze hair structure and help diagnose hair conditions.

UVB radiation changes the chemical makeup and dries out human hair but doesn't alter its appearance or texture.

Scaffoldin helps form hard skin structures in chicken embryos.

Permanent waving weakens hair by altering its protein structure.

Self-assembling RADA16-I hydrogels with bioactive peptides significantly improve wound healing.

A specific protein in chicken embryos links early skin layers to feather development.

Researchers developed a scaffold that releases a healing drug over time, improving wound healing and skin regeneration.

The hydrogel with bioactive factors improves skin healing and regeneration.

Hard skin features like scales, feathers, and hair evolved through specific protein changes in different animal groups.

Disulfide bonds make keratin in hair stronger and tougher.

Selective Androgen Receptor Modulators (SARMs) are drugs that can control the effects of androgens in different tissues, potentially having fewer side effects and promising for treating various conditions.

Water and fatty acids affect hair's surface differently based on hair damage, and models can help understand hair-cosmetic interactions.

Kennedy's disease leads to muscle weakness and sensory issues, has no cure but manageable symptoms, and future treatments look promising.

Peptide hydrogel scaffolds help grow new hair follicles using stem cells.

Yak belly hair has higher porosity and is less stiff than human hair, making it absorb dye better but less suitable as a direct substitute for hair dyeing.

Exosomes show promise for future tissue regeneration.

Silk sericin dressing with collagen heals wounds faster and improves scar quality better than Bactigras.

Environmental factors can cause mutations in skin proteins, leading to skin disorders.

A new mutation in the CYP11B1 gene was found in a woman with mild hyperandrogenemia, a rare cause of non-classic congenital adrenal hyperplasia.

Lipocalin-Type Prostaglandin D2 Synthase (L-PGDS) is a protein that plays many roles in the body, including sleep regulation, pain management, food intake, and protection against harmful substances. It also affects fat metabolism, glucose intolerance, cell maturation, and is involved in various diseases like diabetes, cancer, and arthritis. It can influence sex organ development and embryonic cell differentiation, and its levels can be used as a diagnostic marker for certain conditions.

Peptide hydrogels show promise for healing skin, bone, and nerves but need improvement in stability and compatibility.

New treatments for ichthyosis, like protein replacement and gene therapy, show promise and may become standard care.

3D bioprinting in plastic surgery could lead to personalized grafts and fewer complications.

The GNP crosslinked scaffold with antibacterial coating is effective for rapid wound healing and infection prevention.

Three specific mutations in the LIPH gene can cause hair loss by damaging the protein's structure and function.

Peptide hydrogels heal burn wounds faster and better than standard dressings.
