Employees often have to show emotions they really do not feel in order to offer quality service to clients. For example, a flight attendant has to appear calm and transmit serenity to passengers, even when he/she is
Plants are unable to move away from harmful environmental conditions that affect their well-being and that ultimately compromise their growth and thereby crop production. To cope with a constantly changing environment, they have evolved unique and elaborate
Failure to assemble a division septum occurs in Escherichia coli cells when their supply of FtsZ is blocked. FtsZ, ancestor of eukaryotic Tubulin, is the main component of the divisome, the molecular machinery that drives septation in
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
Our article “Stress is not pain” was a critique on a study by Elwood & Adams who exposed crabs to electric shocks and concluded that their study ‘. . .fulfils the criteria expected of a pain experience’.
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
