While in high-income countries, the majority people die from non-communicable, chronic conditions, nearly 40% of deaths in developing countries are among children under 15 years. Diarrhea is among the top ten leading causes of death and many cases are caused by pathogens transmitted in food and water supplies. This paper introduces major representatives of foodborne parasites and aims to show w...

Obesity is the most common nutrition-related health problem around the world (1), especially among children (2). Hundreds of studies have been conducted to test approaches to prevent obesity, and many were in children in schools (3). Most of these studies were conducted in higher-income countries.

Certainly there are many well known cases of countries where inequality has risen as they became more integrated into the wor...

For more than a decade, the MAPK (mitogen-activated protein kinase) cascade has been studied using mathematical modelling and quantitative experimentation [1]. The MAPK cascade relays the presence of extracellular stimuli such as growth hormones to the nucleus and controls the expression of hundreds of genes. MAPKs control major cell fate decisions such as proliferation, differentiation and apo...
