Summary: The interaction between carboxymethyl cellulose and partially reacetylated chitosan soluble in acidic and alkaline aqueous media was studied through light scattering and isothermal titration calorimetry. It was found that polyelectrolyte complexes (PEC) can be formed in the pH range of 6-8, but lose the ability to complexation in a more alkaline medium. The observed enthalpy of interaction was dependent on the ionization enthalpy of the buffer, indicating proton transfer from the buffer substance to chitosan and its additional ionization in the binding process. This study has potential implications for the development of biocompatible and biodegradable drug delivery systems.

Summary: In this study, DFSP and CFSP nanofibers were successfully fabricated using electrospinning technology. CFSP exhibited better performance in terms of surface hydrophobicity, thermal stability, elasticity, and flexibility compared to DFSP. These results suggest the potential application of FSP nanofibers in functional components or drug delivery, contributing to the high-value utilization of FSP.

Summary: In this study, the interaction between the negatively charged surfactant sodium dodecyl sulfate (SDS) and partially N-reacetylated chitosan (RA-CHI) was investigated. The interaction was found to be exothermic and cooperative in weakly alkaline medium and involved proton transfer from the buffer substance to chitosan. At higher pH values, another mechanism of interaction was observed, involving SDS micellization induced by hydrophobic interactions with polymer segments.

Summary: The stability-indicating HPLC-DAD method developed in this study allows for the simultaneous determination of water-soluble vitamins and their vitamers, with analytical ranges adjusted to recommended dietary allowance values. The method's stability was confirmed through forced degradation studies and peak purity tests, showing higher amounts of vitamins in commercial multivitamin preparations than label claims. The methodology is applicable for stability testing, shelf-life determination, and routine assay analysis of water-soluble vitamins.

Summary: Eligible articles were collected from various databases and searches were conducted using specific terms. The systematic review emphasizes the importance of identifying compounds using fluorescence techniques and suggests the use of cheaper and more accessible techniques. Limited research has been done on Apis mellifera honey in the last 12 years, with some studies focusing on viability rather than quantifying compounds, and others using more costly techniques for fluorescent aspects.

Summary: Donkey milk is considered a good alternative for cow milk in feeding children with milk protein allergy due to its close chemical composition to human milk. Donkey milk has unique advantages in terms of vitamin content, including lower fat-soluble vitamins, higher vitamin C, and higher B-complex vitamins compared to human milk. Further interdisciplinary clinical trials are needed to explore the positive health impact of donkey milk in different sensitive populations, especially children and the elderly.

Summary: This paper reviews the recent development of electrochemical sensors for the detection of vitamins over the past three years. It discusses the importance of vitamins in maintaining human health, the role of electrochemical sensors in detecting vitamins, and specifically focuses on the detection of water-soluble and fat-soluble vitamins. The strategies, performance, challenges, and future prospects of electrochemical sensors for detecting vitamins are also described in detail.

Summary: A growing body of evidence suggests that vitamin supplements play a role in the prevention of cognitive decline. This cross-sectional study found that daily supplementation of vitamin D was associated with a lower risk of Alzheimer's disease in individuals with mild cognitive impairment (MCI), and daily or occasional supplementation of vitamins D, folic acid, and CoQ10 was associated with a lower risk of cognitive impairment in individuals with normal cognitive performance. The findings suggest that daily supplementation of these vitamins, particularly group B vitamins, may be a potential preventive measure for slowing cognitive decline and neurodegeneration in the elderly.

Summary: Vitamins show promise for the prevention and control of diabetes through anti-inflammation, antioxidation, and regulation of lipid metabolism. However, current studies on vitamins in the treatment of diabetes are limited, and there is no clinical data to establish the dose-effect relationship between vitamins and diabetes.

Summary: This review examines the radioprotective effect of vitamins through ex vivo, in vitro, and in vivo studies. A total of 38 articles were included, which investigated the radioprotective effect of vitamins A, C, D, and E either alone or in combination with other compounds. The use of vitamins, either in their natural form or as supplements, can help reduce the negative effects of radiation on the body, organs, and cells. Among the thirteen vitamins, only vitamin E, followed by vitamin C, A, and D, showed radioprotective properties.

Summary: Uterine fibroids are the most common tumors in women and have a significant impact on their quality of life. Previous research on the impact of diet on fibroids is limited, but recent studies suggest that vegetable and fruit consumption may have a beneficial effect, while hypovitaminosis D may increase the risk. Further randomized trials are needed to draw firm conclusions.
