This article describes a new method for staining hair fibers that visualizes keratin filaments without the need for OsO4 fixation or sulfur bond breakage, but it provides no new experimental results beyond the method itself.

In this study, researchers developed an electrochemical method using gold nanostructures on a glassy carbon electrode to detect minoxidil levels in hair lotions, and found it effectively quantified minoxidil in commercial products, revealing discrepancies in their labeled versus actual concentrations.

This study found that the RapidHIT™ ID system can successfully obtain DNA profiles from single hair roots, particularly those with high nuclei counts.

This study found that for metastatic colorectal cancer patients, substituting calcium folinate with disodium folinate in combination with fluorouracil and oxaliplatin showed similar effectiveness and safety as the mFOLFOX6 regimen.

FDG PET/CT can improve cancer treatment plans in dogs.

This study observed that carbon paste electrodes catalyze the electrooxidation of minoxidil more efficiently than other electrode types, with a detection limit of approximately 20 ng mL^-1.

This study introduces a five-modal microscopy technique that allows label-free, in vivo observation and quantitative analysis of various wound healing processes.

This research reports that the ultra-high sulfur keratin promoter acts as a tissue-specific promoter in mouse hair follicles, as shown by induced expression of GFP and β-gal in that region post-transfection.

This study developed a precise and reproducible method for estimating finasteride in tablet formulations using a colorimetric reaction with specific reagents.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

This study describes a double embedding technique for preparing tangential sections of hair and wool fibers, recommending specific staining methods for quantitative analysis and demonstrating wool fiber cortical fractions.

This study describes a new colorimetric method for accurately and precisely measuring finasteride in tablets, with results comparable to the standard HPLC method.

This review highlights that two-photon excitation microscopy is a valuable tool for visualizing live skin structures and immune responses at high resolution, though its clinical use is hindered by safety and cost issues.

In this study, using an ex vivo porcine skin model, researchers found that a 4% nanoparticle concentration significantly enhanced the transport of fluorescein sodium into hair follicles compared to a 2% concentration, while higher concentrations did not further increase penetration depth.

This study established a reliable method for determining residual solvents in Finasteride using gas chromatography.

This study developed and validated a gradient reversed-phase liquid chromatographic method to effectively measure Finasteride and its related impurities in pharmaceutical bulk drugs, demonstrating high linearity and precision.

This study found that FLASH radiation within a Spread-out Bragg Peak retained its normal tissue-sparing effect compared to conventional radiation, with a 40% reduction in acute skin damage and an 18% reduction in fibrotic development in mice.

This study concluded that a liquid serum formulation delivered two fluorescent dyes to deeper follicular regions more effectively than nanoparticle systems.

This study modified nanocomposites with citric acid and hydrazine for potential dual use in cancer imaging and treatment, suggesting they might reduce side effects of traditional chemotherapy.

This study found that arylhydantoin and arylthiohydantoin derivatives with hydroxybutyl or methyl side-chains showed superior androgen receptor binding affinity and may serve as promising radioiodinated AR ligands.

This study validated an HPLC analytical method for evaluating fenasteride in commercial products, finding it to be sensitive, selective, and within acceptance criteria for specificity, precision, and stability, making it suitable for quality control testing.

This study reported the development of two highly sensitive ELISA assays to detect banned substances finasteride and dutasteride in human urine, offering better sensitivity than existing HPLC/MS/MS methods.

This review discusses various chromatographic methods for analyzing finasteride in biological fluids and provides no clinical findings, focusing on detection techniques for different concentration levels.

This study found that mrp/plf-mRNA expression in murine skin increases in response to different tumor promoters, suggesting its potential as a short-term biomarker for chemical carcinogenesis.

This study found that OPC-17116 can be reliably detected in hair, suggesting it can serve as an index of drug exposure and a time-marker in hair analysis.

This thesis developed stimuli-responsive nanocarriers, demonstrating their potential for targeted genetic material delivery with reduced toxicity and diagnostic applications, and explored pH-sensitive nanogels for effective skin drug delivery and monitoring.

This study developed a high-throughput method that identifies bioactive chemicals influencing DHT production in prostate cancer cells, with potential nutraceutical candidates including fucoxanthin, phenethyl caffeate, and Curcuma longa L. extract.

This study reported the development of a workflow that combines SIMS and X-ray elemental mapping techniques for multimodal imaging at the single cell level, successfully applied to visualize elements, metals, and lipids in porcine skin without loss or delocalization.
