This chapter reviews the challenges and future prospects of using nanotechnology and phytochemistry in developing safe, effective, and precision-based therapies for Polycystic Ovary Syndrome, without reporting new clinical findings.

This study found that a nanoemulsion containing perfluorooctyl bromide effectively increased oxygen levels in an anoxic environment, enhancing hair dermal papilla cell growth and significantly promoting hair organ elongation.

This review discusses post-finasteride syndrome, highlighting occasional adverse sexual and systemic effects in men and women, but reports no new research findings while emphasizing the need for better education about the drug's risks.

This article critically examines the relationship between new media and digital games, emphasizing their cultural and historical contexts, but provides no new empirical findings.

This review discusses the role of Nutrease powder in managing hormonal disturbances in polycystic ovary syndrome and reports no new clinical results.

This study found that neonatal administration of finasteride reduced sensitivity to alcohol's motor-stimulating effects and increased preference for novelty and initial alcohol consumption in rats, suggesting a role in alcohol vulnerability.

In this study, repeated finasteride administration was associated with decreased social interaction and cognitive deficits in male rats, potentially linked to changes in cholinergic system activity.

This study found that mTOR gene expression was significantly increased and S6K1 activation was observed in skin samples from acne patients compared to healthy controls, suggesting mTORC1's involvement in acne pathogenesis.

This study found that consumption of dietary supplements and sports nutrition may lead to therapeutic and cosmetic improvements, benefiting skin, hair, and nails while potentially enhancing athletic performance.

In a laboratory study, researchers found that a novel Bioactive Crosslink Repair Complex improved both the protection and repair of chemically damaged hair, enhancing tensile strength, shine, and cuticle alignment when added to bleaching mixtures and leave-in conditioners.

In this study, BCC therapy reduced oxidative stress and cell damage in cardiomyocyte cells, suggesting it may serve as a new treatment alternative for heart disease.

This study discusses the effects of incorporating various amino acids in hair care products, noting improvements in hair surface properties and color retention when integrated with conditioners.

This review discusses recent advances in protein immobilization on bacterial cellulose for various biomedical uses and reports no new clinical results.

PABA helps prevent gray hair and hair loss in mice.

This study found that the co-activator CBP enhances the agonistic action of hydroxyflutamide on androgen receptors, suggesting a mechanism for therapy resistance in prostate cancer.

This chapter discusses the synthesis and analysis of near-infrared fluorescent activity-based probes for imaging cysteine protease activity, reporting potential benefits for disease diagnosis but noting challenges in imaging specific locations with high cathepsin activity.

This study identified that α-ketobutyrate (α-KB) extends lifespan and improves health markers in Caenorhabditis elegans and aged mice by modulating pyruvate metabolism and activating AMPK pathways, with potential implications for human anti-aging treatments.

This study found that elevated beta-hydroxybutyrate levels may worsen the inflammatory immune response in alopecia areata patients and could indicate a poor prognosis with chronic hair loss.

This study found that the protein C4BPA may link insulin resistance and acne vulgaris by influencing lipid metabolism and inflammatory pathways, suggesting it as a potential mediator in the pathogenesis of both conditions.

In this study, PSA levels were significantly lower among African-American men with higher C-peptide levels and Caucasian men with higher HbA1c levels, suggesting a link between metabolic markers and prostate cancer detection.

In this study, Bioactive Collagen Peptides supplementation increased hair follicle cell proliferation and improved hair thickness in healthy women over 16 weeks compared to a placebo.

This study suggests that deficiencies in certain amino acids, like taurine and tryptophan, in artificial milk formulas may contribute to skin and eye problems in Bengal tiger cubs.

This study assessed three lactic acid bacteria-fermented proteins and found that F-WPI and F-SPI could normalize osteoclastogenesis markers in vitro, while F-SPI enhanced osteoblastogenesis markers, suggesting potential as dietary supplements for osteoporosis prevention, though further research into mechanisms is needed.

This review discusses dietary manipulation strategies in a mouse model of CBS deficiency and reports no new results; the authors emphasize the importance of understanding gene-diet interactions.

This study analyzes contemporary theories and practices to understand key factors influencing the development of the examined phenomenon, proposing trends and practical applications for researchers and practitioners, while acknowledging study limitations and suggesting future research directions.
