It is quicker than the other control system in the body namely, the endocrine system. Primarily, the nervous system is divided into two parts. 1. Central nervous system and 2. Peripheral nervous system. http://www.healthfactsinfo.com/introduction_to_nervous_system.html Introduction Abnormal heart sounds are called cardiac murmurs or bruits. The abnormal sounds are produced because of the change in the pattern of blood flow. Normally, blood flows in stream line through heart or the blood vessels. However, during the abnormal conditions like valvular diseases, the blood flow becomes turbulent. This ... http://www.healthfactsinfo.com/cardiac_murmurs.html The prime function of immune system is to protect the host against the invading pathogens. The body tries its best to overcome various strategies of infectious agents (bacteria, viruses), and provides immunity. Some of the important immunological aspects in human health and disease are briefly described. http://www.healthfactsinfo.com/organ_transplantation.html The separations are greatly improved, however, through the use of high-resolution columns and the column retentions times are much reduced. The narrow and relatively long columns are packed with a noncompressible matrix of fine glass or plastic beads coated with a thin layer of the stationary phase. Alternatively, matrix may ... http://www.healthfactsinfo.com/hplc_separations.html In high-performance liquid chromatography (HPLC), a liquid solvent containing a mixture of molecules to be identified is passed through a column densely packed with a small-diameter insoluble bead-like resin. In column chromatography, the smaller and more tightly packed the resin beads, the greater the resolution of the separation technique. In ... http://www.healthfactsinfo.com/hplc_chromatographic_techniques.html The Human Genome Project is a large international effort aimed at determining the sequence of the entire human genome of 3,200,000,000 base pair. But it is much more. Other aims include the creation of physical and genetic maps of the genome, sequencing the genomes of model organisms, developing technology for ... http://www.healthfactsinfo.com/human_genome.html Immunochemical procedures provide protein assay techniques of high sensitivity and discrimination. These methods employ antibodies, proteins produced by an animal’s immune system in response to the introduction of a foreign protein and which specifically bind to this foreign protein. http://www.healthfactsinfo.com/immunochemical_techniques.html The technique exploits the specificity of reaction between an antigen and antibody and molecular sieving of the gel in which this reaction is taking place for analysis of components of a given sample. The technique was developed by Grabar and Williams and is actually a modification of Ouchterlony double diffusion ... http://www.healthfactsinfo.com/immuno_electrophoresis.html Primary ovarian cancer ranks as one of the common causes of cancer deaths in women. Carcinomas are more common in single women and in nulliparous married women. Tumors of germ cell origin are seen in children and teenagers. Women with breast cancer have an increased incidence of ovarian cancer. The ... http://www.healthfactsinfo.com/ovarian_cancer.html Germ-cell tumors Patients presenting with a lump in the testes or a malignancy of unknown origin should have plasma (AFP) and (hCG) measured. If raised due to secretion by the tumor, these measurements can also be used to monitor treatment. However, only about 75% of non-seminomatous germ-cell tumors and a minority ... http://www.healthfactsinfo.com/tumor_markers.html
