Through the decades, researchers have tried to solve the mystery of the enigmatic prefrontal cortex. Along with the famous case of Phineas Gage (Harlow,1848), many studies have attempted to answer the burning question of either or not lesions to the prefrontal cortex lead to an antisocial behavior. The PFC, which is found in the frontal lobe and has an executive function, helps us have an appropriate response to social situations. Why is it important to study this matter? Because we are social creatures

This paper attempts to analyze different imaging modalities as they pertain to the targeting and tracking of stem cells within the body. Nuclear medicine modalities, positron emission tomography (PET) and single photon emission computed tomography (SPECT), are utilized to image the physiological changes within the body and the migration of stem cells. Magnetic resonance imaging (MRI) can be used to target and track stem cells while maintaining their viability. Although these modalities are effective

2.3 β-particle emission radionuclides Β-particles are high energy electrons which are ejected from the nucleus with a range of energies up to a maximal value.12 β-emitters are heavily researched and are a widely accessible form of radionuclide therapy. The LET of β-emitting particles is high enough to kill cancerous cells, but is considered low compared to α-emitters which have a lot more particles in the higher energy levels. Β-particle emitters deposit their energy over a much larger range (1mm

Other uses of nuclear power included Military: The US Navy has all submarines and aircraft carriers moving by nuclear propulsion this lowers petroleum oil use (ships and aircrafts) by 15%. The US Military has several Nuclear Weapons Types: Warheads:The term warhead refers to the explosive and/or toxic material that is delivered by a missile, rocket, or torpedo;Bombs, Atomic Demolition Munition(ADM) ,Artillery Shell,ASW (anti-submarine warfare),ASW warhead,ASW warhead / Bomb, Torpedoes,Inter-continental

atomic number but different in atomic mass.because of their characteristic nature of producing radiation and their energies. Isotopes are used in various areas like industries, agriculture, medical field and research centers. They are decayed by emission of energy in the form of alpha, beta (electron) beta plus (positron) and gamma rays. (1) Types of radiation Alpha particles cannot be used for measurement from outside the body because they are such low penetrating power. A sheet of paper stops alpha

Positron Emission Tomography Positron Emission Tomography is a scanning technique that allows us to measure in detail the functioning of distinct areas of the human brain while the patient is comfortable, conscious and alert. PET represents a type of functional imaging, unlike X-rays or CT scans, which show only structural details within the brain. The differences between these types of imaging don’t end there. In both X-rays and CT scans, a form of radiation is emitted and travels through the

The Impact of DaTscan on the Diagnosis and Management of Movement Disorders: A Retrospective Study. New and evolving diagnostic tests are always exciting. Especially if these tests could possibly lead us to a cure for those diseases that currently have only treatment, but no cures. Parkinson 's is a progressively degenerative disease, which affects millions of people every year. Patients suffering from Parkinson 's incur high costs from drug therapy, fall-related injuries, and hospitalizations

F2. NON DESTRUCTIVE EVALUATION TESTS: Various non-damaging assessment (NDE) tests for solid individuals are accessible to focus in-situ quality and nature. Some of these tests are exceptionally valuable in appraisal of harm to RCC structures subjected to erosion, substance assault, and fire and because of different reasons. The term 'non damaging' is utilized to show that it doesn't impede the expected execution of the auxiliary part being tried/explored. The nondestructive assessment have been comprehensively

An Electrophysiological Study on Brainstem in Type-2 DM Introduction: Diabetes mellitus is a generalized, chronic metabolic disorder manifesting itself, in its fully developed form, by hyperglycemia, glycosuria, increased protein breakdown, ketosis and acidosis. If the disease is prolonged, it is usually complicated by degenerative disease of the blood vessels, the retina, the kidneys and the nervous system1. T2DM is the predominant form of diabetes worldwide, accounting for 90% cases globally
