Growing-up in a stressful environment affects the levels of glutamate in the hippocampus in adult depresses subjects
Mood disorders are emotional disturbances consisting of prolonged periods of excessive sadness, excessive joyousness, or both. Exposure to harsh parenting practices or to maltreatment during childhood can increase individuals’ vulnerability to mood disorders and the severity of
Neuropeptide Y (NPY) is a protein involved in the complex regulation of a variety of physiological functions that range from feeding to emotions. In the central nervous system NPY is able to influence autonomic nervous system regulation
Simulation is an education and training technique that allows students to practice in safe environments that replicate substantial aspects of the real world in a fully interactive fashion. Simulation is often used to train undergraduates as it
Chronic pain affects 100 million US adults and with costs exceeding $500 billion per year. Fibromyalgia (FM) is a prevalent chronic pain disorder characterized by widespread pain, fatigue, anxiety and depression, and problems with memory and concentration.
Poorly controlled diabetes is often associated with various complications including blindness, kidney failure and pain secondary to damaged nerves. However, the most common complications are those related to large blood vessel disease such as heart attacks and
In his influential biopsychological theory of personality, Hans J. Eysenck proposed in 1967 that there was a biological basis to personality. He described two main personality traits which could be measured on a continuum. Individuals scoring high
People gain weight because they eat too much food, particularly food with a lot of fats and sugars, and do not use the calories gained from food. In this case the energy intake is higher than energy
Serving as the building blocks for triacylglycerides and membrane phospholipids, fatty acids are essential in all forms of life. Given their chemical inertness, fatty acids need activation into a more water-soluble form (as acyl-CoA esters), prior to
Energy is an inevitable part and makes life possible. Globally, over 90 percent of transportation energy requirement is met by fossil fuels. International Energy Agency (IEA) predicts that, if we continue to use the fossil fuel at
Plants constantly encounter various biotic and abiotic stresses in the environment. These stresses present adverse growth conditions, which affect the plant development, longevity and productivity. The crop production is decreasing rapidly due to the negative impact of
Application of the fungicide kresoxim-methyl prior to drought and salinity stress imposition enhances the ability of plants to survive
Plants are exposed to multiple environmental stresses ( e. g. drought, salinity ), resulting in major yield losses in modern agriculture. Drought and salinity are the two major abiotic threats for plant production and potentially food security.
As children grow into adults, they face compromises between prolonging growth, and reaching milestones such as puberty and the start of reproduction. They respond to cues in their environment in order to choose the best compromise. In
New drug discovery relies on several phases of safety assessment. One such prominent in vitro safety assessment assay is the “hERG potassium channel assay” for cardiac safety. If a compound blocks the hERG potassium channel in a
The American Psychological Association estimates that more than 70% of Americans regularly experience the physiological or psychological symptoms associated with chronic stress, with a third of the population thought to be living with extreme levels of stress.
Cortisol is an adrenal hormone essential for the maintenance of homeostasis, especially in response to stress. When cortisol levels are increased, this is defined as Cushing’s syndrome (CS). CS can be associated with increased morbidity, and when
Hormesis is a biphasic dose-response pattern in which the response at low doses is opposite to that at higher doses. According to the hormesis concept, a small dose of a potentially harmful agent can exert a beneficial
Stress exposure is known to precipitate psychological disorders. However, large differences exist in how individuals respond to stress; whereas some people thrive under stressful situations, others break down and are at risk to develop psychopathology. One important
Post-traumatic stress disorder (PTSD) is a common psychological response following a traumatic event and affects about 8% of the population. Effective psychological treatments do exist and should be made available to anyone who is diagnosed with PTSD.
Almost a third of all proteins in eukaryotic cells are synthesized and folded in the endoplasmic reticulum (ER) before being secreted and redistributed to other organelles, such as the Golgi apparatus, lysosomes, and the plasma membrane. To
