If obesity were tied only to too much food or too little physical activity, the cure would be a simple matter of counting calories or keeping track of steps with a pedometer. Unfortunately, obesity is much more complex. Many other factors come into play, including so-called hunger genes that make a person more susceptible to obesity, infection with certain pathogens linked to weight gain, hormones...
The human microbiome is a fundamental component of human physiology, with an estimated one-third of circulating metabolites being a product of the gut microbiota. Changes in the microbiome can trigger changes in human cellular activities, resulting in disease or contribute to its progression. Microbiota is considered to be a virtual "code" or a system emerging, with the properties that must...
Each human body hosts, on the surface and inside its body, trillions of microorganisms, which are essential in the functioning of the human organisms. The importance of these communities of microorganisms in our lives is major since researchers all over the world consider them a "second human genome". Understanding how these organisms interact with their human hosts could explain different...
Obesity is a prevalent disease with severe complications. In recent years, interests have been geared towards exploring the relationship between gut microbial factors and the subject's degree of, or propensity to, obesity. With the relative abundance values of phylotypes as features, machine learning algorithms could be applied to identify predictive microbes that distinguish between subjects of different...
The human body plays host to thousands of bacterial species in a variety of ecosystems. Until recently, microbial communities have been impossible to investigate thoroughly, as the vast majority of bacteria cannot be cultured through laboratory techniques. New technologies (e.g. high-throughput sequencing, 16S rRNA surveys) allow us to deeply sample the genetic content of a microbial environment in...
