In this study, NuMA's microtubule-binding domain was found to be crucial for correct spindle orientation and skin differentiation, with its loss leading to neonatal lethality in mice.

This study demonstrated that ablation of individual somatostatin-expressing interneurons increased activity in nearby neurons of the mouse motor cortex during motor learning.

This report expands the known genetic mutations linked to monilethrix by identifying new patients with KRT83 mutations, confirming its role as a causative gene for this hair disorder.

This study found that KRTAP2 proteins predominantly express in the hair shaft cortex of humans, interact with hair keratins, and play crucial roles in hair shaft keratinization.

In this study, the researchers identified the specific subcellular localization of the protein S100A3 in the endocuticle and cortex of human hair shafts.

Pollution exposure speeds up hair damage.

This research examined the ultrastructure of deer hair fibers and found significant variations in diameter, cuticle thickness, and intermediate filament arrangements among different fiber types.

This study found that the cuticle layer of hair contributes approximately 60% to bending stress, highlighting its significant role in the mechanical properties of hair stiffness.

This study found that the 16th-century mummified hair from a female mummy in Paju was remarkably well-preserved, with the hair's ultrastructural features maintained likely due to a calcium-rich surface coat.

This study found that scanning electron microscopy with argon sputter etching visualizes hair lipids at the cell membrane complex as distinctive convex structures, shedding light on their role and localization in human hair.

This study observed that treating human hair with NaOH led to partially removed cuticles, resulting in better fiber cohesion and mechanical properties similar to wool, unlike bleach or formic acid treatments, which weakened the fibers.

This study found that both epithelial and hair keratins are expressed in beard hair medulla cells, exhibiting unique patterns and interactions distinct from other hair follicle and epithelial cells.

This study found that oxidative hair dyes altered the color and ultrastructure of Caucasian hair but did not significantly affect the hair's breaking strength.

Different oils affect hair flexibility and strength, with their impact varying on whether hair is virgin or bleached.

This study used rapid-freezing immunocytochemistry to successfully map the ultrastructural localization of hair keratins in human scalp hair, primarily finding them in macrofibrils in the cortex and endocuticle.

This article discusses the various roles of steroids in vertebrate organ systems and notes several glucocorticoids that were among the Top 200 Drugs by sales in the 2010s, but it reports no new clinical findings.

This study found that human hair exhibits significant deformation in its intermediate filaments under strain, with recovery taking about 1000 minutes, suggesting a self-healing period post-mechanical stress. Additionally, cuticle scales deform much less than the cortex, and the Poisson ratio aligns with soft matter properties.

This study found that pubic hair from Korean males has a thicker cuticle layer with more scales compared to scalp hair, offering better protection against chemical damage, and hypothesizes this evolved as a defense mechanism against exposure to urine and ammonia.

This research highlights the key interactions of hair cosmeceuticals, focusing on their effects on the hair fiber surface, cuticle, and cortex, which are crucial for protection and mechanical strength, particularly in damaged hair.

In this study, researchers found that neonate hairs have a distinct microstructure with no medulla and smaller hair follicles compared to adult hairs.

This study found that the hair of a 16th-century female mummy discovered in Paju was remarkably well-preserved due primarily to a calcium-based surface coating that likely inhibited moisture and microorganism infiltration.

This study demonstrated that using a mass spectrometry imaging technique, researchers were able to visualize the incorporation of argan, avocado, and coconut oils into hair fibers, suggesting their potential in cosmetic and alopecia treatments by confirming oil absorption and fiber modification.

This review found that solar radiation, pollution, and trace metals cause significant damage to human hair, with factors like UVB radiation primarily affecting light-colored and bleached hair; most data were derived from in vitro and ex vivo simulations.

This study observed that repeated perm treatments decrease disulfide bonds in hair due to their conversion largely into cysteic acid, affecting the waving efficiency depending on the reduction agent used.

This review discusses how various factors, including cosmetic procedures and scalp conditions, can damage hair, but highlights the availability of products to improve hair health; it reports no new empirical results.

This article reviews the effectiveness of adrenal cortex compounds E and F in treating various connective tissue disorders and reports no new clinical findings.

This article examines microscopic structural differences and pigment distribution in various rabbit hair colors and reports no clinical results.

This article discusses the effectiveness of adrenal cortex compounds E and F in treating connective tissue disorders like rheumatoid arthritis and lupus erythematosus, but it reports no new clinical results.

This anatomical study on Eclipta alba concluded that unique secretory structures in stems and leaves may serve as identifying features of the plant and the Asteraceae family.

This chapter reviews hair anatomy, hair shaft structure, and various cosmetic treatments that can alter or damage hair, but it presents no new research findings.
