In this study, researchers observed low variability in hair formoterol concentrations for COPD patients with stable adherence, but inter-patient differences and other factors may limit the effectiveness of hair analysis as a reliable tool for assessing medication adherence.

In this comprehensive review, researchers reported that macromolecules like type I collagen, keratin, and ceramides enhance hair health by improving follicular function and increasing hair density, strength, shine, and resilience, as shown in various in vitro, animal, and human studies.

This study demonstrates that polarized second harmonic generation imaging effectively monitors wool fiber stretching, revealing significant structural changes in keratin alignment that improve textile performance.

This study reviews the potential to repurpose human hair waste, often discarded from places like barber shops and hospitals, into valuable raw materials for chemical and materials science applications, despite existing challenges in its utilization.

This study explored the potential of human hair keratin as a filtration material, finding that it may effectively absorb the pollutants diclofenac and perfluorobutanesulfonate. The researchers reported significant binding affinities through molecular simulations, supporting further investigation into keratin's use for water purification.

This article reviews how biopolymers are utilized in cosmetics, highlighting their biodegradable and non-toxic properties, recent structural developments, novel applications, and safety considerations in the formulation of skin, hair, and oral care products.

Hair can't be as strong as Rapunzel's because it's impractical to scale up due to defects.

This review highlights recent advancements in microfluidics for 3D tissue model generation and discusses its applications in tissue engineering and high-throughput drug screening without reporting new experimental results.

This review emphasized the significance of biliary fibrosis in hepatobiliary disorders, exploring its clinical manifestations, epidemiology, and cellular factors, and provided insights into current clinical trials and strategies for managing fibrosis-related cholangiopathies.

This review analyzes the role of silver nanoparticles in wound healing, highlighting their antimicrobial, anti-inflammatory, and tissue-regenerating properties, and emphasizes the need for further research to optimize formulations and ensure safety.

This review examined the diverse therapeutic potentials of cannabinoids, highlighting their applications in pain, neurological, and cancer treatments, and emphasized the benefits of biodegradable polymers in improving drug delivery; however, further clinical trials are needed to fully explore these potentials.

This study proposed the existence of a membrane-like structure between the cuticle and cortex in human hair, which may provide strong protection against external stimuli.

This study found that a highly resistant structure, located at the interface between the cuticle and cortex of human hair, acts as a penetration barrier, which the authors propose to name the "cuticle anchored resistant base" or CARB.

Atomic Force Microscopy is a more accurate way to assess hair damage and the effect of cosmetic treatments.

This study reports that activating Notch signaling in the hair follicle cortex of transgenic mice caused abnormal differentiation of the medulla and cuticle, highlighting potential cell-cell interactions.

In this study, researchers found that the prevalent Glu 410 Lys mutation in hHb6 and a new Glu 403 Lys mutation in hHb1 are linked to monilethrix, suggesting a mutational hotspot in type II hair keratins.

This study found that the aqueous ethanol extract of Myricae Cortex demonstrated in vitro testosterone 5alpha-reductase inhibitory activity and in vivo anti-androgenic effects in mouse and hamster models.

This animal study found that Cinnamomi cortex water extract reduced prostate weight and improved histological changes in a benign prostatic hyperplasia model, suggesting potential as a treatment.

This review discusses the interrelationship between the anterior pituitary's adrenocorticotropic hormone (ACTH) and the adrenal cortex, but reports no new experimental findings.

In this study, researchers identified two new keratin-associated proteins, hKAP1.6 and hKAP1.7, in human hair follicles, contributing to understanding hair fiber differentiation.
