This review discusses the use of microbial biosurfactants as a safer alternative to chemical surfactants in cosmetics due to their antibacterial, moisturizing, and low toxicity properties, but it reports no new clinical findings.

This study developed a 3D ovarian cancer model using microtumours, which effectively mimics minimal residual disease and supports the identification of new drug targets like perhexiline for treatment-resistant cells.

This review discusses the current techniques for engineering microtissues, emphasizing the potential of continuous microfluidic processes to facilitate large-scale production, but reports no new experimental results.

Method detects finasteride in plasma at very low concentrations.

This study quantified around 60 organic pollutants in hair samples from mothers and infants in Spain, finding significant correlations between pollutant levels and factors like residence, dietary habits, and maternal age, with common exposure sources identified for several pollutant classes.

The study concluded that poly(propylene carbonate maleate) microspheres effectively encapsulated finasteride, achieving a biphasic release with prolonged drug release over 5-6 weeks in vitro.

This study observed very high thallium levels in small mammals near a zinc smelter in Poland, accompanied by severe population and health impacts.

This study designed a micromold template for creating controlled-sized, multicellular tumor spheroids, finding that HEK-293 cells formed consistent spheroids with high circularity and viability after 7 days, influenced by cell seeding density and treatment conditions.

Pollution exposure speeds up hair damage.

In this study, researchers found that exposure to PM10 significantly increased inflammation and impaired collagen synthesis in human dermal fibroblasts, suggesting PM10 contributes to skin aging through these mechanisms.

This study reports that prenatal and prepubertal exposure to organochlorine compounds and perfluoroalkyl substances may affect pubertal development at age 12, with observed changes in development patterns in both girls and boys, highlighting the need for further research.

This study suggests that finasteride-loaded polyvinyl alcohol/chitosan microspheres could be a promising embolic agent for benign prostatic hyperplasia, showing effective occlusion and sustained drug release in preclinical models.

This study found that micro-needling with cosmeceuticals or platelet-rich plasma significantly improved wrinkles, skin laxity, scar softening, and hair growth over 12 months, with minimal side effects, and that the best results occur with pigment and platelet massaging between 5 to 30 minutes post-treatment.

This review highlights the potential of microfluidic skin-on-a-chip models in skin research, emphasizing their ability to mimic human skin structure and improve control over cellular and molecular distribution compared to traditional in vitro models.

Phospholipid-coated nanoparticles penetrate hair follicles better than others, especially in pig ears.

This study achieved a first by successfully forming large quantities of dermal papilla spheroidal microtissues, which retained their hair induction potential, using a micropatterned culture system.

This study analyzed 853 articles to reveal that research on silica-based nanobiomaterials in regenerative medicine has rapidly increased, with distinct regional differences in impact and emerging focus areas in drug delivery and wound healing.

In this study on Danio rerio, researchers found that exposure to titanium dioxide nanoparticles did not affect embryonic development but altered the structure of male gonads, acting as potential endocrine disruptors with androgenic activity.

This study demonstrated that finasteride-loaded PLGA microspheres created using a novel microfluidic device exhibit extended drug release in beagle dogs, with modifications allowing for release up to 3 months.

This reprint reviews 14 papers on advances in solid-phase microextraction techniques for bioanalysis, reporting no new results.

In this study, researchers developed a novel periodate oxidation method for extracting keratin micro-units from waste hair and feathers, achieving yields of 31.28% and 20.64% respectively, enhancing the stability of oil-in-water emulsions and suggesting potential for sustainable biomaterial production.

This study found that while parabens in haircare products were within legal limits, all samples contained dibutyl phthalate, raising concerns about chronic exposure to endocrine disruptors.

This study found that nanoparticles did not permeate intact rat skin but could penetrate skin that had been artificially punctured, primarily through grooves or hair follicles.

This study using high-performance liquid chromatography reported that mice with more diverse gut microbiota had higher levels of specific compounds in hair compared to those with less diversity, with stress affecting certain plasma levels.

This review found that synthetic cosmetics pose risks to human health, potentially causing various diseases, and negatively impact ecosystems, air quality, and oceans from production to waste disposal, highlighting the broad environmental and health consequences of cosmetic use.

In this study, penetration of FA-PLGA nanoparticles into hair follicles was observed in excised dog, rat, and porcine skin, with the deepest penetration in porcine skin, suggesting its similarity to human skin for drug delivery studies.

This study demonstrated that the IVL-DrugFluidic® platform is effective for mass-producing finasteride-loaded polymeric microspheres for long-acting injectables, maintaining stable drug release without an initial burst for a month.

This study investigated the ability of a human hair keratin dimer to absorb the pollutants diclofenac and perfluorobutane sulfonate, finding high binding affinities that suggest potential for hair-derived materials in water filtration technologies.

This study found that hair products used by Black women and children in the U.S. contain multiple chemicals associated with endocrine disruption and asthma, highlighting potential exposure disparities and a need for improved labeling.

This study suggests that increased use of anticancer drugs from 2004 to 2008 has led to higher environmental release, necessitating expanded monitoring and research on their ecotoxicological impacts.
