In this study, low-level laser therapy significantly improved the mechanical strength of bone at tooth extraction sites in rats, while neither platelet-rich plasma alone nor combined with laser affected mechanical strength or calcium content.

This study found that a bioactive borosilicate glass containing Sr and Cu ions exhibited promising mechanical strength, biocompatibility, and antibacterial activity, particularly the CuSr-1 wt.% composition, suggesting potential for use in orthopedic implants and bone tissue engineering.

This study found that dyed chitin nanofibers maintain color and mechanical properties when reinforcing resins, allowing color addition and strength improvement while retaining transparency.

In this review paper, the authors explored the composition and role of lipids in human hair, highlighting their importance for hair texture, moisture retention, and tensile strength, while noting that the understanding of hair lipids' functions remains controversial and requires further research.

This study investigated how vitamin A deficiency, certain diseases, and pregnancy affect cattle coat hair structure, finding notable keratin fibril interference under vitamin A deficiency and structural modifications in chronic renal failure, while pregnant cows exhibited superior hair tensile strength compared to non-pregnant ones.

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

This review discusses the strengths and weaknesses of existing studies on complex dietary supplements for hair loss, emphasizing the need for valid measurement methods like TrichoScale® to quantify effectiveness; it reports no new results.

This case report suggests that a proactive physical therapy model can be effective for improving physical function and meeting exercise guidelines in patients newly diagnosed with systemic lupus erythematosus.

In this study, the use of internal wool lipid liposomes was shown to improve the lipid composition and increase the resistance to breaking in both untreated and chemically treated hair fibers.

This study found that using 369LAB Lipid Bond, derived from plant oil triglycerides, can restore lipid content in damaged hair to natural levels and improve hair strength, integrity, and resilience after a single application, with benefits persisting even after discontinuation.

This study developed a biocompatible hair-dyeing technology using a dark polyphenol complex, which demonstrated effective hair coating, improved mechanical strength, and strong antioxidant properties while maintaining high cell viability.

This article reviews the potential clinical use of anabolic steroids in treating muscle loss from chronic diseases and aging and highlights both the benefits and risks of these substances in sports.

The researchers reported that a novel leave-on treatment containing caffeine, niacinamide, panthenol, dimethicone, and an acrylate polymer significantly increased the diameter and improved the mechanical properties of scalp hair fibers, suggesting it may help mitigate thinning hair.

This study describes the development of polyamide 6 composite fibers with amber filler, finding them suitable for use in medical textiles such as compression garments due to their biocompatibility with skin cells.

This study found that keratin intermediate filaments in the hair of GAN patients are altered, showing decreased diffraction signals and increased stiffness, strength, and extensibility.

This issue reviews various reports on branding, including UK consumer attitudes towards brand extensions and company performance in 1999, but provides no new research findings.

This review examines the design and evaluation parameters of depilatory formulations but reports no new empirical findings.

This study developed a novel hair-straightening shampoo incorporating a polyphenol–inorganic sulfate redox agent, finding that it effectively straightens hair while enhancing strength and reducing damage due to its protective polyphenol coating.

In this study, tubular 3D bioprinted structures made from sodium alginate and gelatin, containing NIH/3T3 fibroblast cells, demonstrated the ability for cell growth and network formation over 6 weeks, although structural tensile strength decreased with cell growth and polymer degradation.

This study found that a bio-based repair solution containing hydrolysed wool keratin, serine, and transglutaminase improved the physical and chemical properties of damaged hair, increasing its strength, flexibility, and thermal stability while offering long-lasting protection against chemical damage.

In this study, PRP injections into the muscular layer of rabbits' intestinal walls improved anastomosis regeneration with less adhesion compared to PRP soaking, though further research is needed to determine the best application method.

In this study, injecting platelet-rich plasma into the muscular layer of the intestinal wall in rabbits significantly reduced adhesion development compared to soaking methods, suggesting an improvement in anastomosis regeneration.

This chapter discusses the composition, biocompatibility, and production methods of biomaterials like collagen, chitin, and silk for dermal substitutes, focusing on preclinical and clinical research, but reports no new clinical results.

This study found that down and guard hairs of Inner Mongolia Cashmere Goats have distinct protein compositions and physical properties, with keratin-related proteins potentially influencing these differences.

This study observed that the biophysical properties of hair in Caucasian females with brown hair significantly change with age, and smoking or being overweight was linked to smaller hair cross-sectional areas.

This study suggests that adjusting the ratios of keratin-associated proteins to keratin intermediate filaments can create keratin/chitosan hydrogels with more consistent gel properties for tissue engineering.

This study found that the moisture content of human hair significantly influences the type of fracture under tensile loading, with low or high humidity levels leading to smooth fractures and intermediate humidity resulting in step fractures.

This study describes a new method for extracting red mordant dyes from wool fibers using ethylene diamine tetraacetic acid and N,N-dimethyl formamide, preserving the fibers for further examination.

This study found that the extent of reducing agents' effects on hair fibers was linked to the electrode potential of the reagents used.

The researchers emphasize the limited scope of existing studies on lip aging, highlighting issues that include collagen loss and the deepening of lip lines with age, and suggesting a need for further research to guide cosmetic and clinical interventions.
