research IS AGE MORE THAN JUST A NUMBER? CHARACTERISTICS OF MEN PRESENTING FOR REPRODUCTIVE UROLOGY FERTILITY EVALUATION IN NORTH AMERICA STRATIFIED BY AGE GROUPS
Older men have different fertility histories and factors affecting fertility, suggesting they may benefit from earlier fertility evaluations.
research Partial Reversal of Canities in a 22-Year-Old Normal Chinese Male
A 22-year-old's gray hair partially turned back to its original color without known causes.
research Age-related changes in endogenous glucocorticoids, gonadal steroids, endocannabinoids and their ratios in plasma and hair from the male C57BL/6 mice
Male C57BL/6 mice show age-related fluctuations in certain hormones and their ratios in both blood and hair.
research Glycome profiling by lectin microarray reveals dynamic glycan alterations during epidermal stem cell aging
Aging changes sugar molecules on skin stem cells, which may affect their ability to repair skin.
research Clinical and instrumental characterization of hair and scalp aging in nonbalding Caucasian women
Aging significantly affects the hair and scalp of nonbalding Caucasian women, with changes that differ from male pattern baldness.
research Quantitative determination of nutraceuticals in matured unriped fruits of three edible Musa Species using GC-MS
Unripe fruits of three banana species have many health-boosting compounds useful for medicine.
research Roles of Nutritional Selenium in Mouse Aging and Age‐related Degenerations
Selenium deficiency worsens aging symptoms in mice.
research 364 Mechanical forces of human dermal fibroblasts significantly decrease with age
Skin cell strength decreases significantly as we age.
research Mudanças associadas ao envelhecimento capilar
Hair aging leads to color loss and reduced density, and dermatologists are key in treating it to improve quality of life.
research Hair Aging Revisited: An Expert Delphi Consensus on Pathogenesis, Clinical Features, and Future Therapies
Experts agree on understanding hair aging to improve diagnosis and treatments.
research Biological characteristics of age-related changes in C57BL/6 mice sub-strains in the national center for geriatrics and gerontology aging farm
B6J mice live longer before 24 months, but B6N mice live longer after; both strains show weight gain, increased food and water intake, and health issues as they age.
research Normal Pubertal Development: Part I: The Endocrine Basis of Puberty
Puberty is driven by hormonal changes, mainly influenced by genetics, nutrition, and body fat.
research Mechanisms of skin vascular maturation and maintenance captured by longitudinal imaging of live mice
research Highlights from the Literature
Apoptosis, not oxidative stress, is linked to aging in mice with mtDNA mutations.
research Quantifying effects of aging across structures of the mouse auditory system, with in-vitro brain slice preparations
Chronological age affects the mouse auditory cortex more than hearing loss, and the brain may be less sensitive to mitochondrial dysfunction.
research Aging Skin Microbiology
research Age- and sex-dependence of five major elements in the development of human scalp hair
Calcium and magnesium in hair increase with age and are higher in adult women.
research Ageing and colony-forming efficiency of human hair follicle keratinocytes
Aging reduces the ability of human hair follicle cells to form new cell colonies.
research Cellular Senescence and Aging in Myotonic Dystrophy
Myotonic Dystrophy may age cells faster, and drugs that target aging could be potential treatments.
research Gross morphology and ultrastructural characterization of the skin in Yuyi hairless mice(Mus musculus)
Yuyi hairless mice lose hair after birth, develop thick, loose skin with folds, and show disorganized skin structure as they age.
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.
