research Persistent escalation of alcohol consumption by mice exposed to brief episodes of social defeat stress: suppression by CRF-R1 antagonism
Blocking CRF-R1 can reduce alcohol intake in stressed mice.
research Redefining hormone resistance in prostate cancer
The conclusion suggests that prostate cancer should be classified by castration status and that new therapies targeting androgen receptor signaling show promise.
research Using a capture–recapture method to assess the frequency of adverse drug reactions in a French university hospital
The study found that combining different databases gives a better estimate of drug side effects in hospitals.
research Efficacy of bergamot: From anti‐inflammatory and anti‐oxidative mechanisms to clinical applications as preventive agent for cardiovascular morbidity, skin diseases, and mood alterations
Bergamot may improve heart health, skin conditions, and mood, but more research is needed to confirm these benefits.
research Systematic review of platelet-rich plasma (PRP) preparation and composition for the treatment of androgenetic alopecia
PRP shows promise for hair loss treatment, but needs standardized preparation and composition.
research The Diagnosis and Treatment of Hair and Scalp Diseases
Hair loss requires customized treatments based on its various causes and types.
research Age-related hair changes in men: Mechanisms and management of alopecia and graying
Men's hair loss is caused by hormones and genes, and can be treated with medication and surgery, while graying is due to aging and has no prevention except dyeing.
research The Fusion of Craniofacial Reconstruction and Microsurgery
Combining microsurgery with craniofacial reconstruction improves aesthetic results and reduces harm to the area where tissue is taken from.
research Local and Systemic Reduction by Topical Finasteride or Flutamide of Hamster Flank Organ Size and Enzyme Activity
Topical finasteride and flutamide reduce gland size and enzyme activity, with flutamide being more potent, potentially treating acne, seborrhea, hirsutism, and androgenic alopecia.
research Top applications of dermatologic ultrasonography that can modify management
Ultrasonography in dermatology improves diagnosis and treatment of skin conditions.
research Eccrine sweat glands associate with the human hair follicle within a defined compartment of dermal white adipose tissue
Sweat glands and hair follicles are structurally connected within a specific layer of skin fat.
research Vasoactive intestinal peptide, whose receptor-mediated signalling may be defective in alopecia areata, provides protection from hair follicle immune privilege collapse
A substance called VIP might protect hair follicles from being attacked by the immune system, and problems with VIP signaling could lead to hair loss in alopecia areata.
research Evaluation of the predictive capacity of DNA variants associated with straight hair in Europeans
Certain DNA variants can predict straight hair in Europeans but are not highly specific.
research Integral hair lipid in human hair follicle
Human hair has a protective lipid layer that can be damaged by moisture and treatments, affecting hair growth and health.
research Topical and intralesional therapies for alopecia areata
No treatments fully cure or prevent alopecia areata; some help but have side effects or need more research.
research Biosynthesis of Dihydrotestosterone by a Pathway that Does Not Require Testosterone as an Intermediate in the SZ95 Sebaceous Gland Cell Line
Dihydrotestosterone can be made from dehydroepiandrosterone in skin cells without needing testosterone.
research Dorsal Skin Reactions of Hairless Dogs to Topical Treatment with Corticosteroids
Stronger corticosteroids cause more skin damage in hairless dogs, similar to effects in humans.
research The bright side of fibroblasts: molecular signature and regenerative cues in major organs
Fibroblasts, cells usually linked to tissue repair, also help regenerate various organs and their ability decreases with age. Turning adult fibroblasts back to a younger state could be a new treatment approach.
research Mapping the molecular and structural specialization of the skin basement membrane for inter-tissue interactions
The skin's basement membrane has specialized structures and molecules for different tissue interactions, important for hair growth and attachment.
research Follicular Penetration of Caffeine from Topically Applied Nanoemulsion Formulations Containing Penetration Enhancers: In vitro Human Skin Studies
Nanoemulsion creams with certain enhancers can greatly increase caffeine delivery through skin.
research The Female Pattern Hair Loss: Review of Etiopathogenesis and Diagnosis
Female pattern hair loss involves hormonal factors, genetics, and may be linked to low ferritin levels.
research Androgenetic alopecia and insulin resistance: are they truly associated?
No true link between AGA and insulin resistance, but coexistence may worsen AGA.
research Enzyme Treatment of Wool and Specialty Hair Fibers
Enzymes xylanase and pectinase clean wool and specialty hair fibers effectively without damage, offering an eco-friendly alternative to soap and hot water.
research Effects of PNU157706, a Dual 5α-Reductase Inhibitor, on Rat Epididymal Sperm Maturation and Fertility1
PNU157706 reduced rat sperm movement and fertility without affecting offspring health.
research Pemphigus and associated comorbidities: a cross-sectional study
People with pemphigus are more likely to have conditions like hypothyroidism, inflammatory bowel disease, and diabetes.
research Divergent neuroactive steroid responses to stress and ethanol in rat and mouse strains: relevance for human studies
Stress and alcohol affect brain chemicals differently in rats, mice, and humans, influenced by genetic differences.
research The changes in the hair cycle during gestation and the post-partum period
Hair growth slows and shedding increases after childbirth, but most women don't experience excessive hair loss.
research Methods for quantifying intrafollicular drug delivery: a critical appraisal
The document concludes that there is no agreed-upon best method for measuring drug delivery within hair follicles and more research is needed to validate current techniques.
