150-180 / 1000+ resultsresearch Splitting Hairs: Evaluating the Origin of Human Nakedness
Humans likely became hairless to better regulate body temperature.
research Evidence for biological shaping of hair ice
A fungus is essential for forming and shaping hair ice on dead wood.
research Role of human type II hair keratins in intermediate filament bundling in vitro
research Stress-sensing in the human greying hair follicle: Ataxia Telangiectasia Mutated (ATM) depletion in hair bulb melanocytes in canities-prone scalp
Hair greying is linked to reduced ATM protein in hair cells, which protects against stress and damage.
research Peer Review #1 of "Establishment of an immortalized mouse dermal papilla cell strain with optimized culture strategy (v0.1)"
Scientists improved how to grow mouse skin cells in the lab and created a long-lasting cell line, but didn't fully explain its advantages or compare it to normal cells.
research Specific repair of aging hair keratin
A new keratin treatment can strengthen and protect aging hair.
research Demonstration of Inherent Electromagnetic Energy Emanating from Isolated Human Hairs.
Human hair has electromagnetic properties.
research Direct evidence supporting the existence of a helical dislocation in protofilament packing in the intermediate filaments of oxidized trichocyte keratin
Oxidized trichocyte keratin has a helical dislocation in its structure.
research Contrastive Rhetoric: Development and Challenges
Wound-induced hair growth may help study regeneration and aging, but it's unclear if this ability decreases with age.
research Temporal expression and steroidal regulation of piRNA pathway genes (mael, piwi, vasa) during Silurana (Xenopus) tropicalis embryogenesis and early larval development
The piRNA pathway genes are crucial in early development and may influence sex differentiation through hormone regulation.
research Dermatologic Features of Classic Movie Villains
Most classic movie villains have skin conditions, unlike the heroes, which may cause bias against real people with similar conditions.
research How Should Educators and Publishers Eliminate Racial Essentialism?
Educators and publishers should focus on teaching racism as the cause of health inequity and ensure fair use of race in materials.
research Hair today, gone tomorrow: the degradation and conservation of archaeological hair fibers
Acidic sandy clay damages archaeological hair the most, while dry conditions preserve but make it brittle; silicone oil can help keep the hair flexible.
research Clinical Snippets
Melanoma risk tools need improvement, certain gene mutations cause skin diseases and could be treated by targeting those mutations, skin wrinkling may relate to lung aging due to genetic factors, and oxidative stress affects hair loss but can be reduced in low oxygen.
research LB1017 A novel link between human hair follicle neuroimmunology and mitochondrial biology: Substance P increases intrafollicular oxidative stress and mitochondrial biogenesis
Substance P may contribute to hair loss by increasing oxidative stress and mitochondrial activity in hair follicles.
research Long-lived proteins and DNA as candidate predictive biomarkers for tissue associated diseases
Long-lived proteins may predict age-related diseases.
research Highlights from the Literature
Apoptosis, not oxidative stress, is linked to aging in mice with mtDNA mutations.
research Short sequence repeats of the intergenic spacer regions of ribosomal RNA genes in Malassezia globosa and M. restricta colonizing the scalps of male individuals with and without androgenetic alopecia
A specific DNA pattern in Malassezia restricta may be linked to hair loss in men.
research Unraveling the Strand: A Comprehensive Review on the Forensic Significance of Microscopic Human Scalp Hair Analysis
Microscopic hair analysis is important in forensics but has limitations; new technologies are improving its accuracy.
research 1330 The possible role of PTEN-induced kinase 1-mediated mitophagy by regulating inflammasome activation in the pathogenesis of alopecia areata
Activating mitophagy may help manage a key immune response involved in the hair loss condition alopecia areata.
research FEMALE CADAVER IN THE HAN TOMB NO. 1 X-RAY DIFFRACTION STUDIES ON TWO KINDS OF FIBROUS PROTEIN
The protein structures in the hair and tendon were preserved, but their molecular arrangements changed.
research An Extended Epidermal Response Heals Cutaneous Wounds in the Absence of a Hair Follicle Stem Cell Contribution
Skin can heal wounds without hair follicle stem cells, but it takes a bit longer.
research The Thinning Top: Why Old People Have Less Hair
Old people have less hair because their hair follicles don't regenerate as well, not because of fewer stem cells, and a protein called follistatin might help reactivate hair growth.
research Resistance of degraded hair shafts to contaminant DNA
Degraded hair shafts resist contamination and can be easily cleaned.
research DNA Damage, Checkpoint Responses, and Cell Cycle Control in Aging Stem Cells
Maintaining DNA integrity in stem cells is crucial to prevent aging and cancer.
research Changing faces: can a new identity stop balding?
Changing hair follicle identity could potentially reverse balding.
research Regulation of hard α-keratin mechanics via control of intermediate filament hydration: matrix squeeze revisited
Hard α-keratins stay stiff in water because the surrounding matrix keeps them dehydrated and strong.
research Evolution of long scalp hair in humans
Long scalp hair evolved for cooling and social signaling.
research The Metabolism and Control Mechanism of Human Hair Follicles
Human hair follicles have a unique metabolism that changes between growth stages and may contribute to baldness.
