This guide explores the fundamental science and practical applications of nanocrystal technologies to enhance the bioavailability of poorly water-soluble drugs, detailing synthesis methods, stability solutions, and drug delivery innovations like hydrogel composites and microneedle platforms.

This comprehensive guide from nanotechsci.com explores how nanocrystal technology enhances the bioavailability of poorly water-soluble pharmaceuticals, detailing the science behind crystallization and practical synthesis techniques, and discussing their advanced drug delivery applications across various routes.

In this study, researchers found that the concentrations of cetostearyl alcohol, shea butter, and coconut oil significantly affected the in vitro spreadability of heat protectants, suggesting that optimizing these components could improve product coverage and thermal protection on hair.

This study examines the process of medicalization over the past two centuries, particularly focusing on its social and cultural implications, with a critical perspective on practices around sexuality, reproduction, and diagnoses like homosexuality and hysteria, questioning when medical authority may be overstepped.

This study suggests that idiopathic hirsutism may involve higher local androgen synthesis despite normal serum androgen levels, challenging its categorization as idiopathic.

This study found that methylcellulose-based hydrogels can effectively deliver growth hormone through the skin, with albumin increasing the hormone's permeation to 93% in simulated in vivo conditions.

In this study, researchers created a coamorphous system combining tadalafil and finasteride that demonstrated improved solubility, dissolution, and stability compared to their physical mixture, offering potential therapeutic advantages for benign prostatic hyperplasia.

This study found that hyaluronic acid increased the size of hair follicle germ-like aggregates and the number of proliferative cells but did not maintain specific markers during the process.

This abstract discusses the pervasive promotion and marketing of plastic and cosmetic procedures, without reporting any new clinical findings.

This study observed that human hair keratin showed distinct morphological features depending on the dissolution speed, which could have potential applications in clinical settings for developing self-tendons.

This article introduces the term "anisotrichosis" to describe the significant variation in hair shaft diameters observed in pattern alopecia, drawing a parallel to anisocytosis seen in blood smears, but reports no new research findings.

This study observed phenotypic diversity in hair loss among Japanese individuals homozygous for the LIPH c.736T>A mutation and suggests that differences in hair thickness may contribute to varying severities.

This study developed and validated a mass spectrometric method to measure hydroxy-androgens in serum, which aids in understanding androgen synthesis in castration resistant prostate cancer.

This study found that using a bicomponent reduction system with TGA and DTDG for hair straightening limited hair damage by forming only thiol groups, while a TGA-only system formed more damaging mixed disulfide groups.

In this case series study, mild ovarian hyperstimulation syndrome was reported in only one out of 118 PCOS patients receiving highly purified HMG injections for IVF treatment.

In this study, the researchers found that tyndallization effectively sterilizes aqueous solutions of hyaluronic acid without diminishing their regenerative properties, and these properties remain intact even at low temperatures, supporting potential applications in cryobiology and cryomedicine.

This study found that ultrasonication pre-treatment at various power levels improved the color, protein solubility, and degree of hydrolysis of fish protein hydrolysates from mackerel side streams, and potentially reduced bitterness by decreasing hydrophobic free amino acids.

This article provides guidelines for molecular genetic testing of congenital adrenal hyperplasia due to 21-hydroxylase deficiency, focusing on quality requirements, methodologies, and variant classification; it reports no new clinical results.

In this study, researchers developed a coamorphous form of tadalafil and finasteride, showing improved solubility and dissolution in vitro, with results successfully translated in vivo in rats. They reported reasonable stability, suggesting this form could serve as a therapeutic alternative to the current marketed combination.

The researchers reported that increasing protein content in human hair keratin/calcium alginate blend films led to larger molecular aggregates, which influenced the films' physical properties such as light transmittance and tensile strength.

In this study, researchers found that ligand homodimerization controls the receptor binding specificity of the FGF9 subfamily, preventing off-target activation of FGFR "b" isoforms.

This study introduces a novel method for digitizing hair color that accurately captures and renders the color appearance of physical hair samples in synthetic images.

This study found that a new hybrid polymer made from hydrolyzed protein, alkyl chain, and silicone helped prevent discoloration and improve moisture feel and manageability in dyed and damaged hair.

This study found that individualized GAHT regimens, including microdosing, effectively improved gender congruence and quality of life for non-binary individuals, but some experienced a decrease in bone mineral density.

This case report describes a 46,XY female patient with a novel homozygous nonsense mutation in the LHCGR gene, highlighting the need for molecular analysis in disorders of sexual development.

Poly(ethylene-co-vinyl alcohol) monoliths can be made using heat separation for various uses.

This updated guidance from the GRADE working group addresses issues with assessing inconsistency in treatment effect estimates and evaluating the credibility of effect modifiers in systematic reviews.

This study found that using an ultrasound hollow microneedle array enhanced transdermal delivery of finasteride, accelerating hair regrowth in mice with androgenetic alopecia compared to other delivery methods.

This article explores the theoretical foundations of the ChromaLens Precision Mapping system for analyzing hair, but it does not present any new experimental findings.
