This study demonstrates that pH-responsive nanogels designed with comb-like anionic polymers significantly improved oral delivery of the chemotherapy drug camptothecin, enhancing drug stability in acidic conditions and release in the intestines, with increased cellular uptake and cytotoxic effects against colorectal carcinoma cells.

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 found that hydrophobic amino acids from egg white hydrolyzed protein and L-phenylalanine effectively penetrate deep into the human hair fiber, increasing specific contents in both virgin and bleached hair.

This study reported that mice on a phenylalanine-deficient diet showed symptoms such as weight loss, gastric dilation, and thymic depletion, which echo human phenylalanine deficiency manifestations.

This study identified 18 significant metabolites and two enriched metabolic pathways, necroptosis and ABC transporters, in serum samples of acne patients with and without insulin resistance, potentially aiding in the clinical diagnosis and drug development for these patients.

This study found that a missense mutation in the FGF5 gene is associated with hair-length differences among various dog breeds.

This study explored non-invasive methods for monitoring low molecular weight biomarkers on the skin's surface, concluding that certain amino acid ratios, such as Phe/Trp, could serve as potential indicators of skin inflammation and cancer.

This study documented a case of an 11-month-old with PKU who developed acrodermatitis enteropathica-like symptoms due to severe phenylalanine deficiency, requiring dietary adjustment to restore phenylalanine levels.

This study reports that the Swedish newborn screening program for phenylketonuria, galactosaemia, and biotinidase deficiency is effective, with high sensitivity and specificity, and lower false positive rates compared to other countries, while genetic variants impact detection and incidence patterns in Sweden.

This study suggests that minoxidil may serve as a suitable reference drug for high permeability classification in the Biopharmaceutics Classification System due to its consistent permeability across different intestinal segments and pH levels.

This article discusses the widespread issue of zinc deficiency affecting plant, animal, and human health, and reports no new clinical results; the authors emphasize the need for adequate zinc availability in agriculture and nutrition.

This study characterized the physical-chemical properties of Eclipta alba and identified compounds in the plant that could support its use in developing hair loss treatments.

This study reported a 6.3% prevalence of PCOS among women in a Sri Lankan community, with most cases presenting as oligo/amenorrhea and polycystic ovaries.

This review explores the role of Foxn1 in mammalian skin biology, discussing its influence on hair follicle function and the potential for further research to enhance understanding of epithelial differentiation.

This study reported successful repigmentation without scarring in patients with localized and segmental vitiligo after epidermal grafting, but the Koebner phenomenon hindered similar results in some with generalized vitiligo.

This review suggests that most mutations in the SRD5A2 gene show no clear genotype-phenotype correlation in 5-α-Reductase deficiency, although mutation location affects severity.

In this study, rheumatoid arthritis patients showed no changes in the number of circulating follicular helper T cells, but these cells had increased CD200 expression, implicating them in disease pathogenesis and suggesting CD200/CD200R as a potential therapeutic target.

This study identified a large deletion in the desmoglein 4 gene as the genetic basis of the Iffa Credo "hairless" rat's skin phenotype, linking it to lanceolate hair mutations.

This case study reported a rare occurrence of lepromatous leprosy with Lucio phenomenon in a 50-year-old Indonesian living in Malaysia, highlighting the necessity for primary care practitioners, even in non-endemic areas, to recognize this serious leprosy reaction to prevent complications and transmission.

In this case report, folliculitis decalvans with frontal fibrosing alopecia was observed in a patient with a dark phototype, highlighting the phenotypic spectrum of folliculitis decalvans and lichen planopilaris.

This research suggests that mouse mutants and genomics can help study hair biology and epithelial differentiation by focusing on the role of the Foxn1 gene.

This study found that young indigenous South Asian women with polycystic ovary syndrome are more likely to be centrally obese and have metabolic syndrome, particularly with increasing age, higher BMI, and acanthosis nigricans.

This study found a strong correlation between antioxidant activity and phenolic content in rosemary, influenced by bioclimatic and seasonal factors in different stages of Tunisia.

This study found that Greek women with classic PCOS phenotypes have a higher risk of metabolic syndrome and impaired glucose homeostasis compared to those with newer PCOS phenotypes.

This study reports that both a 9-month-old with phenylketonuria on a phenylalanine-free diet and mice on a deficient diet exhibited severe health issues, highlighting the need for cautious dietary management.

This study reports that using machine learning models, particularly XGBoost and Random Forest, can accurately predict PCOS phenotypes based on non-invasive data, with cycle length as the most significant predictor.

This review critically examines Forensic DNA Phenotyping, highlighting high accuracy in predicting certain traits but also legal and ethical challenges, particularly around regulatory fragmentation and issues of genetic privacy.

This study reports that NIH PCOS is linked to more severe metabolic issues, including higher obesity and insulin resistance, compared to non-NIH PCOS phenotypes.

This review discusses how women with PCOS have an increased risk of insulin resistance and cardiometabolic features regardless of body fat, and calls for targeted prevention and management strategies.

This study found no significant differences in metabolic characteristics between different phenotypes of PCOS or between women with PCOS and healthy controls among reproductive-aged Iranian women.
