The “Rare” or “Non-LCH” Histiocytic Disorders in Childhood: A Brief Overview
Diseases of the monocyte, macrophage and dendritic cell system are referred to as histiocytoses. Based on improved understanding of their pathobiology and molecular background histiocytoses have been recently re-classified into five groups. Nevertheless, for practical reasons the histiocytoses are grouped into: Langerhans cell histiocytosis (the most common entity), hemophagocytic lymphohistioc...
متن کاملThe effects of fasting on physiological status and gene expression; an overview
Calorie restriction through ingesting no or minimal amounts of food and caloric beverages for periods of time is called fasting. Fasting can affect body through changing in physical and metabolic adaptations, as well as mineral and hormonal status. However, psychological effects and sometimes medical complications are likely in case of inappropriate fasting. Fasting is associated with changes i...
متن کاملEffects of Ramadan fasting on blood pressure in hypertensive patients: a systematic review
Ramadan is a holy month for Muslims and fasting in this month is the rule for any healthy matured person. Nutritional and behavioral changes occurred during Ramadan fasting may lead to several physiological change, such as blood pressure (2). Studies evaluated the effects of Ramadan fasting on blood pressure in hypertensive patients, are scarce and reported inadequate results. In this paper a s...
متن کاملOverview of Direct Numerical Simulation of Particle Entrainment in Turbulent Flows
An overview of removal and re-entrainment of particles in turbulent flows is presented. The procedure for the direct numerical simulation (DNS) of the Navier-Stokes equation via a pseudospectral method for simulating the instantaneous fluid velocity field is described. Particle removal mechanisms in turbulent flows in a duct are examined and effects of the near-wall coherent eddies on the parti...
