research UV SPECTROPHOTOMETRIC METHOD FOR DETERMINATION OF FINASTERIDE IN BULK AND PHARMACEUTICAL DOSAGE FORM
The method measures finasteride accurately and cheaply using UV light.
research Chirality Effect on Physical and Biological Properties of Peptide-Based Hydrogels
Chirality affects the structure, strength, and function of peptide-based hydrogels.
research Original article / Article original External post mortem artefact: a key issue in hair result interpretation
Hair test results can be misleading due to external contamination, so they shouldn't be used alone to assess long-term drug use.
research Staining of human skin with RGB trichrome unveils a proteoglycan-enriched zone in the hair dermal sheath
A new staining method shows a special area in the hair's skin layer with lots of proteoglycans.
research Fabrication and Characterization of Electrospun Membranes Based on “Poly(ε-caprolactone)”, “Poly(3-hydroxybutyrate)” and Their Blend for Tunable Drug Delivery of Curcumin
The PCL/PHB blend allows for slower, more controlled curcumin release than individual polymers.
research Reverse Protein Engineering Of Firefly Luciferase
The protein's size was reduced, but more work is needed to confirm its function.
research Individual Human Hair Keratin Rapidly Extracted Through the Advanced Oxidation Process and Their Hemostatic and Wound Healing Evaluations
The new method extracts keratin from hair faster and better, and the resulting product improves blood clotting and wound healing, with potential for personalized treatments.
research Amino Acid Content of Damaged Human Hair
High temperatures and certain chemicals can significantly change the amino acid content in human hair.
research Resistance of degraded hair shafts to contaminant DNA
Degraded hair shafts resist contamination and can be easily cleaned.
research The effects of hydrophobic modifications on the interaction of human hair with water
Hydrophobic modifications make human hair less affected by water.
research Chirality Effect on Physical and Biological Properties of Peptide-Based Hydrogels
Chirality influences the structure, strength, and biological uses of peptide-based hydrogels.
research Multimodal Ion Beam Imaging to Correlate Elements and Metabolites at the Micron Scale Using Water Cluster Secondary Ion Mass Spectrometry and MeV Ion Beam Analysis
The method effectively images and correlates elements and metabolites in tissue samples at a micron scale.
research The diagnosis of nonclassic congenital adrenal hyperplasia due to 21-hydroxylase deficiency, based on serum basal or post-ACTH stimulation 17-hydroxyprogesterone, can lead to false-positive diagnosis
Using 17-hydroxyprogesterone levels to diagnose nonclassic congenital adrenal hyperplasia can result in many incorrect diagnoses.
research Alkylation of human hair keratin for tunable hydrogel erosion and drug delivery in tissue engineering applications
Alkylation of human hair keratin allows for adjustable drug release rates in hydrogels for medical use.
research Investigation of human hair using ToF-SIMS: From structural analysis to the identification of cosmetic residues
The conclusion is that a new method can identify cosmetic residues on hair and match them to their products.
research Future Directions: Gene Polymorphism Diagnostics Relevant to Hair
research Development of a Liquid Chromatography/Mass Spectrometry-Based Inhibition Assay for the Screening of Steroid 5-α Reductase in Human and Fish Cell Lines
A new method was created to test the effectiveness of Dihydrotestosterone (DHT) inhibitors, like finasteride and dutasteride, in human and fish cells. The results showed fish cells are more sensitive to these treatments, and dutasteride works better than finasteride in all tested cells.
research Investigation of human hair fibers using lateral force microscopy
Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.
research Dyeing regions of oxidative hair dyes in human hair investigated by nanoscale secondary ion mass spectrometry
Hair dye colors mainly target melanin granules in black hair.
research Kinetic Studies with Transglutaminases
Transglutaminases work through a ping-pong mechanism, and human plasma and platelet transglutaminases have similar catalytic subunits.
research The toughening transition in hair keratin
The observed "toughening" in keratin was actually due to water evaporation, not a real change in keratin.
research Bio-Catalytic Action of Pseudomonas DL17 on Environmental Contaminant Sunset Yellow FCF
Pseudomonas DL17 can completely break down the harmful dye Sunset Yellow FCF in 48 hours.
research 144 Evaluation of contamination and quantification of drug penetrations studies using Quantitative Mass Spectrometry Imaging
QMSI effectively maps and quantifies drug distribution in skin tissues.
research Dihydroartemisinin loaded nanostructured lipid carriers (DHA-NLC): evaluation of pharmacokinetics and tissue distribution after intravenous administration to rats.
DHA-NLC may improve drug delivery and reduce side effects for cancer treatment.
research Liquid Protein Diets and Telogen Effluvium: A Case Report
A liquid protein diet caused hair loss in a young woman.
research Avaliação da estabilidade da Finasterida, estudos de compatibilidade fármaco-excipientes e controle de qualidade das formulações farmacêuticas sólidas do mercado
Finasteride is stable except in high pH, and lactose and magnesium stearate should be replaced in formulations.
