research Androgen Receptor Antagonists (Antiandrogens) Structure-Activity Relationships
Antiandrogens like flutamide are effective in treating conditions like prostate cancer and hair loss, but there's a need for more potent versions. Understanding their structure can help develop better treatments.
research Recent advances in oxasteroids chemistry
New methods to make oxasteroids show promise for medical treatments like osteoporosis and breast cancer.
research Pharmacology of different progestogens: the special case of drospirenone
Drospirenone is a unique progestin with anti-water retention and potential blood pressure benefits, used in birth control and hormone therapy.
research Identification of Anabolic Selective Androgen Receptor Modulators with Reduced Activities in Reproductive Tissues and Sebaceous Glands
Two new compounds were found to build bone and muscle without affecting reproductive organs and skin oil glands.
research Mechanism of action of bolandiol (19-nortestosterone-3β,17β-diol), a unique anabolic steroid with androgenic, estrogenic, and progestational activities
Bolandiol, a synthetic steroid, builds muscle and bone without greatly affecting sex glands, and works differently from other hormones.
research Effect of estrogens on skin aging and the potential role of SERMs
Estrogens help reduce skin aging, and SERMs might offer similar benefits without the risks of hormone therapy.
research Sex Hormones and Related Compounds, Including Hormonal Contraceptives
The document concludes that sex hormones and related compounds have various effects on health, with both potential benefits and risks.
research Hormonal contraceptives: pharmacology tailored to women's health
New hormonal contraceptives are safer, have fewer side effects, and offer health benefits for women.
research Control of Human Hair Growth by Neurotrophins: Brain-Derived Neurotrophic Factor Inhibits Hair Shaft Elongation, Induces Catagen, and Stimulates Follicular Transforming Growth Factor β2 Expression
Brain-Derived Neurotrophic Factor (BDNF) slows down hair growth and promotes hair follicle regression.
research Testosterone-stimulated weanlings as an alternative to castrated male rats in the Hershberger anti-androgen assay
Using testosterone-stimulated weanling rats can effectively replace castrated rats for anti-androgen testing, reducing animal stress.
research Problems Associated with the Recognition and Confirmation of Low-Dose Endocrine Toxicities
Confirming low-dose endocrine toxicities is difficult and requires more research.
research Selective androgen receptor modulators (SARMs) have specific impacts on the mouse uterus
GTx-024 and Danazol affect the uterus like DHT, while GTx-007 has little impact.
research Recent Insights in Multi‐Target Drugs in Pharmacology and Medicinal Chemistry
Multitarget drugs are needed to better treat complex diseases.
research Reproduction of the human relevant potency threshold (HRPT) for estrogen receptor alpha agonism in an inference performance screen for ICCVAM’s regulatory scientific confidence framework
A new method effectively predicts estrogen-related health effects for early screening.
research Observation of the Expression of Vascular Endothelial Growth Factor and the Potential Effect of Promoting Hair Growth Treated with Chinese Herbal BeauTop
The Chinese herbal supplement BeauTop can potentially boost hair growth and thickness by increasing a protein called Vascular Endothelial Growth Factor.
research Поняття міжкультурної комунікації та порівняльна характеристика німецької та української культур (на матеріалі німецької мови)
Low-dose effects in rodent studies are hard to confirm due to confounding factors and control group variability.
research Fetal growth following temporary exposure of day 3 ovine embryos to an advanced uterine environment
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.
research Androgens stimulate specific aspects of maternal nest-building and reduce food intake in rabbits
Androgens boost certain nest-building behaviors and greatly reduce food intake in rabbits.
research Insights learned from L457(3.43)R, an activating mutant of the human lutropin receptor
The L457(3.43)R mutation in the human lutropin receptor causes increased activity and hormone insensitivity, leading to precocious puberty.
research Elevated ornithine decarboxylase activity promotes skin tumorigenesis by stimulating the recruitment of bulge stem cells but not via toxic polyamine catabolic metabolites
Increased ODC activity leads to skin tumors by recruiting stem cells, not by toxic byproducts.
research Estrous Cycle-Dependent Changes in Basal and Ethanol-Induced Activity of Cortical Dopaminergic Neurons in the Rat
research L-Ornithine ketoacid-transaminase assay in hair roots of homozygotes and heterozygotes for gyrate atrophy
research Case 3: The Hypothermic Newborn
The infant with a urea cycle disorder improved with treatment and a liver transplant.
research Effects of Retinoic Acid Exposure in utero on Mouse Vibrissal Follicle Development
Prenatal retinoic acid exposure did not affect mouse vibrissal follicle development.
research The Effects of Perinatal Androgen Deprivation on Locomotor Activity in Male Rats
Blocking androgens in male rats increased estrogen and made them more active.
research Mitotic activity in the epidermis of the rabbit stimulated with local applications of testosterone propionate
Testosterone applied to rabbit skin increases skin cell growth and changes skin structure.
research Inhibiting Biosynthesis and/or Metabolism of Progestins in the Ventral Tegmental Area Attenuates Lordosis of Rats in Behavioural Oestrus
