In this study, purebred Dexter cows with higher levels of winter hair shedding weaned heavier calves and had better reproductive success compared to cows with lower shedding levels.

This study observed that beef cattle with certain prolactin receptor gene mutations, known as slick mutations, demonstrated improved post-weaning growth and temperature regulation in a hot, humid climate compared to other genotypes, suggesting genotype influences growth efficiency and heat tolerance.

This study found that puppies fed organic selenium had better retention of selenium compared to those fed inorganic selenium, with no significant difference in coat quality or hair growth.

This study found that single-born cashmere goats had higher birth weights, pre-weaning growth rates, and superior cashmere production attributes compared to twin-born goats, despite twin-born goats achieving compensatory growth post-weaning.

This study found that weanling rats fed diets with oxidized rapeseed oil or lard had increased heart lipid levels, various symptoms of fat toxicity, and organ-specific tissue damage.

This study found that unilateral neutron irradiation in pigs significantly decreased the uptake of radioactive zinc in blood, impaired growth, and led to decreased organ weights and hair pigmentation changes on the irradiated side.

This study found that rats fed a diet with different protein qualities and levels showed significant differences in hair cycle length, daily weight gain, and hair density.

This study found that crossbred lambs fed liquid diets with reconstituted cow's milk initially grew wool without crimp, with crimp resuming two weeks post-weaning.

In this study, dietary biotin supplementation showed no significant benefit on reproductive performance in sows or pre-weaning growth and mortality in piglets.

This study found that substituting soy hulls for corn-based supplements did not significantly affect ewe growth, reproductive performance, or lamb performance in pasture-based hair sheep systems.

In this study, sows fed a diet with added biotin weaned more pigs per litter overall, though other reproductive and health metrics showed no improvement.

In this study, a low-methionine diet significantly improved the health and physical traits of cystathionine β-synthase-deficient mice, contrasting with negative effects on mice with partial deficiency.

This study found that sows consuming beet pulp had higher feed intake and improved litter performance during heat stress, while a high-fiber diet enhanced insulin levels, suggesting dietary fiber's importance for reproductive and metabolic health in sows.

Different sports can cause specific skin conditions that need proper diagnosis and treatment.

In this study, normal weight adolescents with PCOS showed increased insulin resistance and significantly lower levels of high molecular weight adiponectin compared to controls, despite no other metabolic differences.

This article introduces a new theory on male pattern baldness, attributing it to scalp pressure affecting hair follicles, and suggests it could revolutionize understanding and treatment; no clinical results are presented.

This review discusses the potential impact of endocrine-disrupting chemicals and body size on pubertal onset and progression, highlighting critical gaps and priorities for future research without presenting new clinical results.

Finasteride affects male rat genitalia development, causing abnormalities during specific pregnancy days.

This study observed that electro-acupuncture reduced global DNA methylation and DNMT3b expression in a PCOS-like rat model, suggesting a role of hypothalamic DNA methylation in PCOS development and treatment.

The researchers observed that pregnancy in rhesus monkeys was associated with an increased incidence of hair loss, though the underlying reasons remain unclear.

This study found that selecting Angus cattle for early puberty reduced their prolactin levels, which may indicate a response to changing day length.

This review evaluates hair growth measurement methods for human scalp hair, suggesting that combining highly resolutive analytical approaches with global calibrated methods is recommended for assessing hair changes in clinical settings.

This review highlights that human hair is a valuable biological matrix for clinical and toxicological analyses, demonstrating its applicability in detecting various active substances from different pharmacological classes.

Hair extensions can cause hair loss and scalp damage, and these problems might be more common than people realize.

This review discusses perceptions and side effects of depot medroxyprogesterone acetate and emphasizes the importance of educating teens to enhance compliance; it reports no new clinical findings.

This study found that in overweight or obese women with PCOS, certain baseline subcutaneous adipose tissue genes significantly predicted weight loss response to a 4-month behavioral lifestyle intervention, with the gene GSTM5 as the strongest predictor.

This study reported that new-onset skin conditions such as acne vulgaris emerged in children during the Covid-19 pandemic, potentially linked to mask use and the psychosocial stress of the pandemic.

This study investigated the effects of wool-derived hydrolysed keratin peptides on relaxed textured hair and found that mid- and high-molecular weight peptides improved mechanical strength and reduced breakage in different humidity conditions.

This study found that men born with very low birth weight had higher median serum estradiol levels but similar reproductive patterns compared to men born at term.

This study conducted a genome-wide association analysis on 1,125 ewes and identified 24 SNPs associated with wool production traits, and highlighted potential candidate genes like ADAR and TP53 for further research into the genetic mechanisms influencing wool growth in sheep.
