research Procyanidin B‐3, isolated from barley and identified as a hair‐growth stimulant, has the potential to counteract inhibitory regulation by TGF‐β1
Barley extract, specifically procyanidin B-3, can promote hair growth and counteract growth inhibition.
research Old world monkeys
Old World monkeys are important for research but require proper social housing and welfare to ensure valid results and minimize stress.
research Cortisol determination in hair and faeces from domestic cats and dogs
Hair cortisol can reliably indicate chronic stress in cats and dogs.
research Alopecia: possible causes and treatments, particularly in captive nonhuman primates.
Alopecia in captive primates can be caused by many factors, so thorough testing is needed before blaming stress.
research Influence of external factors on hair cortisol concentrations
External factors can significantly affect hair cortisol levels, so it's not always a reliable stress marker.
research Hair Cortisol in Sheltered Cows and Its Association with Other Welfare Indicators
High hair cortisol levels indicate stress in cows due to poor shelter conditions and health issues.
research Protein deficiency in a colony of western lowland gorillas (Gorilla g. gorilla)
Gorillas in Gabon improved after protein supplements were added to their diet.
research Spontaneous zinc deficiency in marmosets, saguinus mystax.
Adding zinc to marmosets' water improved their health, indicating their diet lacked enough zinc.
research Within-person changes of cortisol, dehydroepiandrosterone, testosterone, estradiol, and progesterone in hair across pregnancy, with comparison to a non-pregnant reference group
Hormone levels in hair change during pregnancy, with progesterone increasing significantly compared to non-pregnant women.
research Evaluation of Hair Characteristics and Animal Age on the Impact of Hair Cortisol Concentration in Feedlot Steers
Older steers have higher hair cortisol levels than younger steers.
research Whole blood transcriptome profiling identifies candidate genes associated with alopecia in male giant pandas (Ailuropoda melanoleuca)
Researchers found genes linked to hair loss in male giant pandas.
research Coat color and other factors influencing hair cortisol concentration in domestic cats
Black hair in cats has higher cortisol levels than white hair.
research Structure and Expression of a New Complementary DNA Encoding the almost Exclusive 3β-Hydroxysteroid Dehydrogenase/Δ5-Δ4-lsomerase in Human Adrenals and Gonads
Human adrenals and gonads have a unique enzyme for steroid hormone production.
research Extensive Challenges and Pending Advances in the Study of 5-Alpha-Reductase Isoenzymes. A Literature Review
5α-reductase enzymes are crucial in certain disorders, and while treatment advances exist, more research on SRD5A3 is needed.
research Effects of the prenatal and postnatal nurturing environment on the phenotype and gut microbiota of mice with polycystic ovary syndrome induced by prenatal androgen exposure: a cross-fostering study
Prenatal and postnatal environments both affect PCOS development and gut microbiota in mice.
research The use of hair cortisol for the assessment of stress in animals
Hair cortisol is a reliable way to measure long-term stress in animals.
research Short communication: Factors affecting hair cortisol concentrations in lactating dairy cows
Tail switch hair is best for measuring cortisol in Holstein cows, with white hair and multiparous cows showing higher levels.
research Time course of cortisol loss in hair segments under immersion in hot water
Hot water and UV exposure reduce hair cortisol levels, with the back of the head showing the most consistent levels.
research Stress and the Hair Growth Cycle: Cortisol-Induced Hair Growth Disruption.
High stress can disrupt hair growth, but certain supplements might help.
research Dissolving microneedles: Applications and growing therapeutic potential
Dissolving microneedles show promise for delivering medication through the skin but face challenges like manufacturing complexity and regulatory hurdles.
