Molecular analyses have become an integral part of biomedical research as well as clinical medicine. The definition of the genetic basis of many human diseases has led to a better understanding of their pathogenesis and has in addition offered new perspectives for their diagnosis, therapy and prevention. Genetically, human diseases can be classified as hereditary monogenic, acquired monogenic and polygenic diseases. Based on this classification, gene therapy is based on six concepts: (1) gene repair, (2) gene substitution, (3) cell therapy, (4) block of gene expression or function, (5) DNA vaccination and (6) gene augmentation. While major advances have been made in all areas of gene therapy during the last years, various delivery, targeting and safety issues need to be addressed before these strategies will enter clinical practice. Nevertheless, gene therapy will eventually become part of the management of patients with various liver diseases, complementing or replacing existing therapeutic and preventive strategies. 展开更多

Fruit processing is the appropriative way to augment fruit intake. The present paper shows production technology, which is based on the characteristics of selected raw materials and does not use sugar (saccharose). The objective of the present paper is to produce healthful and disease preventive beverages based on "Saperavi" red wine and bilberries, using grape juice concentrate and stevioside, a natural sweetener, instead of saccharose. The technology is based on the removal of alcohol at a low temperature and low pressure. In these conditions about 50% of moisture is evaporated. The extract is then diluted with 0.25% of stevioside liquid and the ratio is 1:1. The working name is "Saperavi-S". Bilberry juice is added to this beverage at the ratio of 1: l in order to enrich it with biologically active substances. The working name of this beverage is "Marnidan". The products have high contents of phenolic compounds, mainly-anthocyanins. The main idea of technology uses bilberry juice with grape juice concentrate. Bilberries have quite high antioxidant activity, amounting to 55% against l,l-Diphenyl-2-picrylhydrazyl. It is the first time we have produced a beverage based on dealcoholized red wine, stevioside and bilberry juice. This beverage is of special importance in terms of its disease-preventive qualities, including prevention of diabetes, one of the most widespread chronic diseases. 展开更多

Big Data applications in the health service field have gradually been paid more close attention. Based on big data technology, more and more health information platforms are beginning to take effects, such as disease prevention, precision medicine, reducing expenditures for medical care and public health, improving medicine research and development. Meanwhile, the platforms have to face a lot of risks, such as health data disclosure, dispute of health data ownership, implicit contradiction explicit, unsustainable platform operation and so on. With the solutions of these risks, the construction of the public platform can provide better service for the citizens, hospital, pharmaceutical company, R&D institutions or and other parties. 展开更多
