The assay effectively detects hormonal activity of certain chemicals.
research Acute oral toxicity and phytochemistry of Catharanthus roseus and Schwenckia americana used as antidiabetic plants in Southern Benin
Catharanthus roseus and Schwenckia americana extracts are generally safe but may cause kidney and liver tissue damage.
research Acute dermal and ocular irritation testing of rice bran supercritical CO2 extract (RB-SCE) and 0.5% RB-SCE essence product
Rice bran extract caused moderate skin irritation but no eye irritation, while a diluted essence was not irritating to skin and only slightly to guinea pigs.
research 0557 Possible Contributory and Protective Factors in Medication Associated Obstructive Sleep Apnea (OSA): Results from the US Food and Drug Administration (FDA) Adverse Events Reporting System (FAERS)
Some drugs may increase the risk of obstructive sleep apnea, while others like certain biologics might decrease it.
research Skin and hair on-a-chip: in vitro skin models versus ex vivo tissue maintenance with dynamic perfusion
The Multi-Organ-Chip improves the growth and quality of skin and hair in the lab, potentially replacing animal testing.
research A Perspective on RNAi-Based Biopesticides
RNAi-based biopesticides could be safe and effective for pest control with careful development and risk assessment.
research Morphological analysis of patchy thickening and reddish discoloration of active hair growth areas in the skin of New Zealand White rabbits
Rabbit skin with active hair growth shows thicker, redder areas due to larger, more numerous hair follicles and increased blood vessels.
research A hair-follicle reconstructed in vitro immunocompetent skin model for prediction of the sensitizing potential of chemicals
The new skin model can predict how chemicals might cause skin allergies.
research Anticancer drugs in surface waters
Anticancer drugs are increasingly found in surface waters, and their long-term environmental effects are not well understood, requiring better testing methods.
research Penetration of drugs through skin, a complex rate-controlling membrane
The skin is a complex barrier for drug penetration, but understanding its structure and interactions can improve drug delivery methods.
research Transdermal Permeation of Drugs in Various Animal Species
Pig skin is a good substitute for human skin to measure drug absorption, but differences in skin structure and enzymes across species must be considered.
research EMQN best practice guidelines for molecular genetic testing and reporting of 21-hydroxylase deficiency
The guidelines ensure accurate genetic testing and reporting for 21-hydroxylase deficiency.
research Permeation of topically applied caffeine through human skin – a comparison of in vivo and in vitro data
Caffeine penetrates human skin in lab tests similarly to real-life conditions, but actual skin use is still essential for accurate results.
research Self-assembled polymeric nanocarriers for the targeted delivery of retinoic acid to the hair follicle
The new micelle formulation delivers acne treatment more effectively and safely than current gels.
research What should it take to describe a substance or product as 'sperm-safe'
Products should be called 'sperm-safe' only after thorough, well-designed tests.
research Influence of massage and occlusion on the ex vivo skin penetration of rigid liposomes and invasomes
Massage increases how deep both rigid and flexible liposomes can go into skin, with flexible ones going deeper, and covering the skin (occlusion) helps rigid ones more.
research Comparison of rheological properties, follicular penetration, drug release, and permeation behavior of a novel topical drug delivery system and a conventional cream
The new drug delivery system releases the drug better in sebum and targets follicles more effectively than the conventional cream.
research Transdermal finasteride delivery via powder-carrying microneedles with a diffusion enhancer to treat androgenetic alopecia
