research Evaluation of Hair Cycle and Epidermal Turnover.
The document concluded that there are differences in hair growth cycles and skin cell turnover rates, which can be measured with electronic equipment.
research Circulating testosterone and feather-gene expression of receptors and metabolic enzymes in relation to melanin-based colouration in the barn owl
Barn owls with smaller black spots have higher testosterone levels, which might be due to genetic effects on hormone regulation rather than hormone effects on coloration.
research Differential distribution and genetic determination of eccrine sweat glands and hair follicles in the volar skin of C57BL/6 mice and SD rats
C57BL/6 mice and SD rats have different sweat gland and hair follicle patterns, useful for skin research.
research Determining Cortisol in Animal Hair as a Marker of Chronic Stress
Hair cortisol can indicate animal stress but varies with many factors.
research Characterization of the serotoninergic system in the C57BL/6 mouse skin
Mouse skin can produce and process serotonin, with variations depending on hair cycle, body location, and mouse strain.
research Distribution of bacterial community structures on human scalp hair shaft in relation to scalp sites
Bacterial communities on scalp hair are unique to each person but consistent across different scalp sites.
research Gene polymorphisms and serum levels of BDNF and CRH in vitiligo patients
Certain gene variations and different levels of BDNF and CRH hormones are linked to vitiligo.
research Photobiomodulation of human dermal fibroblasts in vitro: decisive role of cell culture conditions and treatment protocols on experimental outcome
Different lab conditions and light treatment methods change how human skin cells respond to light therapy.
research Correlation of cortisol in 1-cm hair segment with salivary cortisol in human: hair cortisol as an endogenous biomarker
Hair cortisol levels can reflect salivary cortisol levels in humans.
research Carbon, nitrogen, and sulfur elemental and isotopic variations in mouse hair and bone collagen during short-term graded calorie restriction
Calorie restriction changes the elemental and isotopic makeup of mouse hair and bone.
research Live imaging reveals chromatin compaction transitions and dynamic transcriptional bursting during stem cell differentiation in vivo
Stem cell differentiation involves gradual chromatin changes and dynamic gene activity.
research INTERACTION OF α-MELANOCYTE-STIMULATING HORMONE, MELATONIN, CYCLIC AMP AND CYCLIC GMP IN THE CONTROL OF MELANOGENESIS IN HAIR FOLLICLE MELANOCYTES IN VITRO
α-MSH and cyclic AMP boost melanin production, while cyclic GMP and melatonin reduce it.
research Does hair cortisol concentration reflect measurable regulatory biology of the HPA axis in healthy humans?
Hair cortisol concentration partly reflects HPA axis regulation but doesn't capture all its complexities.
research The murine hair follicle is a melatonin target
Melatonin directly affects mouse hair follicles and may influence hair growth.
research Sequence Variation in Caprine KRTAP6-2 Affects Cashmere Fiber Diameter
Different versions of the KRTAP6-2 gene in goats can lead to thinner cashmere fibers.
research Mutation in human hair keratin hHb6 in monilethrix: clinical variation is not due to genetic variation.
research Observation of phenotypic variation among Indian women with polycystic ovary syndrome (PCOS) from Delhi and Srinagar
Indian women with PCOS from Delhi and Srinagar show different symptoms, with Delhi women having higher obesity and blood sugar issues, and Srinagar women showing more hair growth and testosterone levels.
research Complex Hair Cycle Domain Patterns and Regenerative Hair Waves in Living Rodents
Mice hair growth patterns get more complex with age and can change with events like pregnancy or injury.
research Change in Hair Cycle and Hair Length in Nude Mice by Administration of Deuterium Oxide
Deuterium oxide extends the hair cycle duration in mice without changing hair structure.
research Factors influencing alopecia and hair cortisol in rhesus macaques (Macaca mulatta)
Captive management practices affect hair loss and stress in rhesus monkeys, with differences between facilities.
research Inter-species differences in wound-healing rate: a comparative study involving primates and rodents
Humans heal wounds slower than non-human primates and rodents.
research Melatonin increases growth properties in human dermal papilla spheroids by activating AKT/GSK3β/β-Catenin signaling pathway
Melatonin may help hair growth by affecting cell growth and hair-related signaling pathways.
research Food Administration and Not Genetic Variants Causes Pharmacokinetic Variability of Tadalafil and Finasteride
Food intake, not genetics, affects how the body processes tadalafil and finasteride.
research Intraretinal variation in disease severity in the Oat mouse model of gyrate atrophy
The Oat mouse model shows mild retinal degeneration, useful for testing treatments.
research Hair as a retrospective calendar of cortisol production – increased cortisol incorporation into hair in the third trimester of pregnancy
Hair can show increased cortisol levels during late pregnancy.
research Prolactin Signaling Influences the Timing Mechanism of the Hair Follicle: Analysis of Hair Growth Cycles in Prolactin Receptor Knockout Mice*
Prolactin affects when mice shed and grow hair.
research Hair cycle in dogs with different hair types in a tropical region of Brazil
Boxer and Labrador dogs' hair growth is affected by the tropical climate, but Schnauzers' is not.
research CLK1 and its Effects on Skin Stem Cell Differentiation
CLK1 is needed for skin cells to become epidermal cells but not sebocytes.
research P381 Kinetics of Titan cells generation and transcriptome modifications comparing three in vitro protocols
Three different methods were compared for creating Titan cells, a type of fungus cell. The OZ method made the most cells initially, but the number dropped quickly. The EB method also made a lot of cells, but the number also dropped. The AA method made fewer cells, but the number stayed steady. The methods also affected which genes were active in the cells.
