Efficacy and safety assessments are essential thresholds for drug candidates from preclinical to clinical research. Conventional mammalian in vivo models cannot offer rapid pharmacological and toxicological screening, whereas cell-based or cell-free in vitro systems often lead to inaccurate results because of the lack of physiological environment. Within the avian species, chick is the first bird to have its genome sequencing. Meantime, chick embryo is an easily operating, relatively transparent and extensively accessible model, whose physiological and pathological alterations can be visualized by egg candler, staining and image technologies...

Systems medicine is a paradigm for translating in silico methods developed for modelling biological systems into the field of medicine. Such approaches rely on the integration of as many data sources as possible, both in the dimension of disease knowledge and patient data. This is a challenging task that can only be implemented in clinical routine with the help of suitable information technology from the field of Medical Informatics. For the research project "Clinically-applicable, omics-based assessment of survival, side effects, and targets in multiple myeloma" (CLIOMMICS) we developed a prototypical systems medicine application system...

The human health is seriously affected by central nervous system(CNS) diseases, but the pathogenesis of CNS diseases is still not completely clear. Currently, the drugs used to treat CNS diseases are mainly receptor modulators and neurotransmitter inhibitors, which have serious side effects; and there are short of drugs for treating CNS diseases clinically. Studies suggest that animal medicines mainly include protein, polypeptide and small-molecule compounds, and have such pharmacological effects in calming, resisting convulsions and improving brain tissues...

There is no doubt that the traditional Chinese medicine(TCM) is effective, practical and scientific after it was used for thousands of years. However, the mechanisms of action of many TCM are still unclear because of their multi-component, multi-target and multi-level features, which hinder the modernization and internationalization of the TCM. Proteomics is to analyze the composition and activity of intracellular proteins which are changing dynamically from a holistic perspective. It is consistent with the holistic and dynamic views of the TCM and brings about the hope of clarifying the mechanism of action of the TCM...

The relationship between intestinal stem cells (ISCs) and the surrounding niche environment is complex and dynamic. Key factors localized at the base of the crypt are necessary to promote ISC self-renewal and proliferation, to ultimately provide a constant stream of differentiated cells to maintain the epithelial barrier. These factors diminish as epithelial cells divide, migrate away from the crypt base, differentiate into the postmitotic lineages, and end their life span in approximately 7 days when they are sloughed into the intestinal lumen...

Traditional high-throughput drug screening in oncology routinely relies on two-dimensional (2D) cell models, which inadequately recapitulate the physiologic context of cancer. Three-dimensional (3D) cell models are thought to better mimic the complexity of in vivo tumors. Numerous methods to culture 3D organoids have been described, but most are nonhomogeneous and expensive, and hence impractical for high-throughput screening (HTS) purposes. Here we describe an HTS-compatible method that enables the consistent production of organoids in standard flat-bottom 384- and 1536-well plates by combining the use of a cell-repellent surface with a bioprinting technology incorporating magnetic force...
