The document tests knowledge and decision-making in hematology through multiple-choice questions.
research Basics of Hormonal Contraception
Hormonal contraceptives are effective for teens but require careful consideration of side effects and individual health.
research Neonatal finasteride induces anxiogenic-like profile and deteriorates passive avoidance in adulthood after intrahippocampal neurosteroid administration
Finasteride given to baby rats causes anxiety-like behavior and worsens learning from punishment in adult rats.
research Effect of finasteride on the ovulatory function of normal women
Finasteride doesn't affect ovulation in normal women.
research Allopregnanolone mediates the exacerbation of Tourette-like responses by acute stress in mouse models
Stress worsens Tourette symptoms by increasing allopregnanolone levels.
research Isoallopregnanolone reduces tic‐like behaviours in the D1 CT ‐7 mouse model of Tourette syndrome
Isoallopregnanolone may be a safe and effective treatment for reducing tics in a mouse model of Tourette syndrome.
research Physiopathological role of the enzymatic complex 5α-reductase and 3α/β-hydroxysteroid oxidoreductase in the generation of progesterone and testosterone neuroactive metabolites
The enzymes 5α-reductase and 3α/β-hydroxysteroid oxidoreductase help create brain-active substances from progesterone and testosterone, which could be used for treatment, but more research is needed to ensure their safety and effectiveness.
research GABRA2 Alleles Moderate the Subjective Effects of Alcohol, Which are Attenuated by Finasteride
GABRA2 gene variations impact alcohol response, and hair loss medication finasteride reduces some effects.
research Steroidal 5α-reductase and 17α-hydroxylase/17,20-lyase (CYP17) inhibitors useful in the treatment of prostatic diseases
Certain drugs that block specific enzymes can help treat prostate diseases.
research Steroid 5α-Reductase Inhibitors
New steroidal compounds could be effective for treating conditions related to 5α-reductase enzyme activity.
research Recent advances in oxasteroids chemistry
New methods to make oxasteroids show promise for medical treatments like osteoporosis and breast cancer.
research Consequences of steroid-5α-reductase deficiency and inhibition in vertebrates
Lack or blocking of SRD5a, a key component in hormone creation, can lead to conditions like pseudohermaphrodism and affect hair growth, bone mass, muscle strength, and reproductive health. More research is needed on its regulation from fertilization to adulthood.
research Progesterone-induced stimulation of mammary tumorigenesis is due to the progesterone metabolite, 5α-dihydroprogesterone (5αP) and can be suppressed by the 5α-reductase inhibitor, finasteride
Progesterone byproduct 5αP stimulates mammary tumor growth, but finasteride can suppress it.
research Recent Advances in the Chemistry and Pharmacological Activity of New Steroidal Antiandrogens and 5α-Reductase Inhibitors
New compounds show promise for treating hair loss, enlarged prostate, and prostate cancer, with some being more effective and having different side effects than current treatments.
research Discovery of Natural Steroid 5 Alpha-Reductase Inhibitors
Natural herbal compounds might treat certain medical conditions by reducing DHT levels, but more research is needed to confirm their effectiveness and safety.
research The First Syntheses of 16β-Chloro- and 16β-Bromo-cyproterone Acetate
Scientists made two new chemicals that might help treat diseases caused by male hormones.
research Early postnatal allopregnanolone levels alteration and adult behavioral disruption in rats: Implication for drug abuse
Changing allopregnanolone levels in baby rats affects their adult behavior and alcohol use.
research Exploring phytoandrogens: A review of their potential in health and medicine
Phytoandrogens from plants may help treat low testosterone naturally.
research Steroidogenesis in steroid related cancers
Steroid-producing capabilities in certain cancers may contribute to treatment resistance.
research Dermatological medication effects on male fertility
Some dermatological medications can impair male fertility, so consult a doctor before trying to conceive.
research The nutritional biochemistry of wool and hair follicles
Nutrients like vitamins, copper, zinc, and amino acids are crucial for healthy hair and wool growth.
research Effects of isotretinoin on the hair cycle
Isotretinoin at a low dose for three months does not significantly affect hair growth.
research Evidence-Based and Potential Benefits of Metformin in the Polycystic Ovary Syndrome: A Comprehensive Review
Metformin helps with menstrual cycles and insulin levels in PCOS but is less effective for hair growth, diabetes prevention, and weight loss, and may improve fertility and reduce diabetes risk.
research Fetal Programming of Polycystic Ovary Syndrome by Androgen Excess: Evidence from Experimental, Clinical, and Genetic Association Studies
Exposure to too much androgen before birth might cause polycystic ovary syndrome later in life.
research COVID-19 and Sex Differences
Men are more likely to have severe COVID-19 cases and fatalities than women due to factors like lifestyle, aging, and biological differences.
research Differential Expression of Fibromodulin, a Transforming Growth Factor-β Modulator, in Fetal Skin Development and Scarless Repair
Fibromodulin might help reduce scarring if increased in adult wounds like in fetal skin that heals without scars.
research BMP-FGF Signaling Axis Mediates Wnt-Induced Epidermal Stratification in Developing Mammalian Skin
Wnt signaling is essential for forming the skin's spinous layer through a BMP-FGF pathway.
research Potential adverse effects of long-term testosterone therapy
Long-term testosterone therapy can cause hormone suppression, affect prostate and heart health, and alter physical characteristics, but does not increase prostate cancer risk and needs more research for full risk assessment.
research Targeted two-photon chemical apoptotic ablation of defined cell types in vivo
A new laser technique can precisely remove specific cell types in living animals without harming nearby cells.
