Precision medicine is a new approach in medical sciences aimed at individualizing treatment, reducing adverse drug reactions (ADRs), and decreasing health care costs. Precision medicine is also able to maintain the health of individuals by regulating their composition of microorganisms (microbiota) using specific methods. Microbiota is the total stock of microbial species in different organs of...

Microbiota is a collection of microorganisms that live in the oral cavity, respiratory tract and intestine of multicellular organisms. Microbiota exerts numerous physiological and pathological effects on the organism in which it resides. Increasing attention has been directed to the host-microbiota interaction, which is highly relevant to the development of carcinogenesis. Changes in the compos...

Background: Colorectal cancer is one of the most common malignant tumors, Human guts harbor abundant microbes that adjust many aspects of host physiology.  Increasing studies show that gut microbiota plays a significant role in the incidence and expansion of CRC, as a result of virulence factors, bacterial metabolites, or inflammatory pathways. Materials and Methods: In this study, viability o...

 Personalized nutrition is a new approach in medical sciences that is based on genetic profile, individual needs, and environmental conditions considering health status and chronic diseases of every person. Studies have shown that genetic differences cannot solely justify various responses to medications and diets, and other important factors including gut microbiota are also involved. Human bo...

Evidence is supported the hypothesis that any changes in the composition and function of the gut microbiota play a fundamental role in a number of chronic inflammatory diseases including celiac disease (CD). In the last decade, several culture-independent methods have been developed to identify the components of the human microbiome. The study of microbiota based on nucleic acid analysis found ...
