Dioxadet and cisplatin show similar efficacy in the CIPC route. Compared with CIPC IP chemotherapy by chemoperfusions is more effective for both the drugs. Dioxadet in HIPEC showed highest survival benefit whereas largest effect during NIPEC is achieved with cisplatin.
The development of new express methods for the analysis of the efficacy of anticancer therapy on the cellular level is highly desirable for the analysis of chemotherapeutic agent performance. In this paper we suggest the use of parameters of cell morphology determined by holographic microscopy and tomography for the effective label free quantitative analysis of cell viability under antitumor chemotherapy and thus of cytostatic agent efficacy. As shown, measured phase shifts and cell morphology change dramatically as a result of chemotherapy and depend strongly on the cell type and agent applied. Experimentally, a comparative analysis of the antitumor efficacy of the two cytostatics, cisplatin and dioxadet, that are commonly used for chemotherapy of disseminated ovarian carcinoma has been performed. The experiments were carried out on the Wistar rat model. An essential difference in the morphology of cells, both normal (erythrocytes) and cancerous, present in ascitic fluid taken from the non-treated group of rats and the groups treated with either dioxadet or cisplatin, has been observed. The results obtained can be interpreted as an indication of the antitumor performance of both cytostatics at the cellular level and as a demonstration of the higher efficacy of therapy with dioxadet as compared to that with cisplatin. Differences in cell morphology are suggested to be applied as quantitative markers of cell viability and cytostatic agent efficacy. The conclusions made are supported by a comparison with the results of recent experiments based on survival rates of laboratory animals treated with these agents.
The human microbiota is formed under the influence of external factors, among which a healthy diet plays a key role. The modern people microbiome changes under human eating behavior, stressful factors, agricultural industrialization, increased environmental load, and alimentary disease risks. The human gut microbiome is recognized as the most important biological interface between human genetics, environment, and lifestyle. Nutrition science is entering a new era of targeted action on the body's metabolic activity through the formation of a healthy microbiome, taking into account men individual nutritional characteristics. The paper presents the design of healthy food product technologies, the molecular concept of food engineering and molecular gastronomy, their relationship with traditional cooking and modern cuisine. Much attention is paid to the description of main components and directions of modern molecular gastronomy development, innovative technologies, and ingredients. The role of dietary fibers, prebiotics and probiotics for the normalization of gastrointestinal tract is indicated from the position of the adequate nutrition theory. Some scientific studies on probiotic and metabiotic effects on gut microbiome are described. Modern advances in food biotechnology allow us to obtain symbiotic microbiological culture consortia for new healthy food product manufacture including molecular gastronomy technologies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
