While many of these adverse effects improve over time, some may persist and become troublesome, requiring a change of drug. These drugs act by increasing the synaptic levels of the hormone serotonin – a chemical messenger involved in mood enhancement. This […]

Brain tumors are classified based on numerous factors. These may be related to the exact location of the tumor, the nature of the tissues that have turned malignant or other factors. Classification of brain tumors Brain tumors are classified based on whether they are malignant (cancerous) or benign (non-cancerous). Brain tumors are also classified based on whether they have originated […]

Down syndrome or Down’s syndrome is a genetic condition caused by the presence of an additional copy of chromosome 21 in a person’s cells. This additional DNA causes the physical characteristics and developmental problems associated with the syndrome. The extra copy of chromosome 21 (also referred to as trisomy 21) is acquired by chance and although Down’s syndrome is more […]

Although it may seem intricate at a first glance, capillary electrophoresis is an instrumental technique with very simple principles. Minute capillaries are used for the electrokinetic separation of analytes in an electrolyte solution under the influence of a given electric field. Capillary electrophoresis is a superior form of electrophoresis. It reduces the problem of sample overheating. This is due to […]
