Cells have evolved an elegant tuning mechanism to maintain tissue integrity, in which increasing mechanical tension stimulates actin assembly at cell-cell junctions. The mechanosensitive junctional protein α-catenin acts through vinculin and Ena/VASP proteins to reinforce the cell against mechanical stress.

Background: During the initial phase of an infection, there is an upregulation of inducible nitric oxide synthase in the macrophages for the production of nitric oxide. This is followed by the recruitment of polymorphonuclear leukocytes (neutrophils) which release arginase. Arginase competes with inducible nitric oxide synthase for a common substrate L-arginine. Objective: To investigate whethe...

BACKGROUND The atypical antipsychotic drug aripiprazole binds with high affinity to a number of G protein coupled receptors, including dopamine D₂ receptors, where its degree of efficacy as a partial agonist remains controversial. METHODS We examined the properties of aripiprazole at D₂-like autoreceptors by monitoring the changes of dopamine synthesis in adult rat brain striatal minces incub...

BACKGROUND Nutrition is one of the important components of health, functional independence and quality of life in elderly population. In this age group, malnutrition is common and the risk of malnutrition increases with the advancing age. Nutritional status acts as a modifying factor in the development of many oral diseases. AIM To assess the relationship of salivary factors, dental caries an...
