Most theories on the pathophysiology of depression are based on measurement of indirect markers‚ neuro-imaging techniques‚ and post-mortem studies. Studies show that depression starts with abnormalities in the areas of the brain that are responsible for reward response‚ mood regulation‚ and executive functions. The neuro-imaging and post-mortem studies have indicated morphological changes shown by reductions in grey-matter volume and glial density in the prefrontal cortex and the hippocampus‚ which

Chronic pancreatitis pathophysiology is unclear. However‚ Long tern alcohol use causes hypersecretion of protein in pancreatic productions‚ this then causes protein plugs and calculi to form inside the pancreatic channels. Therefore‚ alcohol abuse has a direct poisonous impact on the cells of the pancreas. Subsequently‚ patients with eating regimens such as low protein and high or low in fat are more at risk. Smoking is another aspect on the improvement of chronic pancreatitis (J V. Tsirambidis‚

Exam Case Scenario Pathophysiology of Asthma Asthma is a chronic lung disease characterized by episodes in which the bronchioles constrict due to oversensitivity. In asthma‚ the airways (bronchioles) constrict making it difficult to get air in or out of the lungs. Breathlessness is the main symptom. The bronchi and bronchioles become inflamed and constricted. Asthmatics usually react to triggers. Triggers are substances and situations that would not normally trouble an asthma free person. Asthma

he pathophysiology of ADHD is unclear and there are a number of competing theories.[87] Research on children with ADHD has shown a general reduction of brain volume‚ but with a proportionally greater reduction in the volume of the left-sided prefrontal cortex. These findings suggest that the core ADHD features of inattention‚ hyperactivity‚ and impulsivity may reflect frontal lobe dysfunction‚ but other brain regions particularly the cerebellum have also been implicated.[88] Neuroimaging studies

Doctorate degrees are usually required for research positions and also provide an advantage in every area. A Doctorate is required for university teaching. It would also be wise to take the fundamentals of engineering exam shortly before or after graduation. Those who pass the exam are given the designation engineer in training. Practical experience in the field work under guidance of experienced engineers‚ which is frequently provided by summer internships for college students on a competitive basis

PATHOPHYSIOLOGY OF MYOCARDIAL INFARCTION Mechanisms of Occlusion Most MIs are caused by a disruption in the vascular endothelium associated with an unstable atherosclerotic plaque that stimulates the formation of an intracoronary thrombus‚ which results in coronary artery blood flow occlusion. If such an occlusion persists long enough (20 to 40 min)‚ irreversible myocardial cell damage and cell death will occur.5 The development of atherosclerotic plaque occurs over a period of years to decades
