[Comparative characteristics of oxidative modification intensity of proteins in infant milk formulas].

Cow's milk is mainly used in the production of infant milk formulas. However, the protein composition of cow's milk differs significantly from the proteome of breast milk. In addition, various technological factors significantly affect the properties and structure of proteins, susceptibility to oxidative processes.

Extrinsic and intrinsic preanalytical variables affecting liquid biopsy in cancer.

Liquid biopsy, through isolation and analysis of disease-specific analytes, has evolved as a promising tool for safe and minimally invasive diagnosis and monitoring of tumors. It also has tremendous utility as a companion diagnostic allowing detection of biomarkers in a range of cancers (lung, breast, colon, ovarian, brain). However, clinical implementation and validation remains a challenge.

Glioblastoma-derived extracellular vesicle subpopulations following 5-aminolevulinic acid treatment bear diagnostic implications.

Liquid biopsy is a minimally invasive alternative to surgical biopsy, encompassing different analytes including extracellular vesicles (EVs), circulating tumour cells (CTCs), circulating tumour DNA (ctDNA), proteins, and metabolites. EVs are released by virtually all cells, but at a higher rate by faster cycling, malignant cells. They encapsulate cargo native to the originating cell and can thus provide a window into the tumour landscape.

Decoding vesicle-based precision oncology in gliomas.

Extracellular vesicles (EVs) represent a valuable tool in liquid biopsy with tremendous clinical potential in diagnosis, prognosis, and therapeutic monitoring of gliomas. Compared to tissue biopsy, EV-based liquid biopsy is a low-cost, minimally invasive method that can provide information on tumor dynamics before, during, and after treatment. Tumor-derived EVs circulating in biofluids carry a complex cargo of molecular biomarkers, including DNA, RNA, and proteins, which can be indicative of tumor growth and progression.

[Intensity of processes of oxidative modification of proteins in women's and cow's milk].

Breast milk is a source of all the essential nutritional components necessary for the full growth and development of the child, therefore, it is necessary to study its composition and physical and chemical properties in order to adapt human milk substitutes. Adapted infant milk formulas are produced mainly from cow's milk, bringing formula nutrient composition closer to the composition of women's milk, adapting it in accordance with the requirements of the infant body. However, technological processes for the production of dairy products contribute to the activation of oxidative reactions, the violation of protein conformation.
