X Ray Irradiation Essay

Furthermore, X-ray of higher energy than required for imaging is used for radiation therapy. The radiation therapy makes use of ionization radiation (and no images) for the treatment of diseases, such as

- Even though the X-ray expose patient to harmful radiation it is used to see inside the human body and diagnose broken bones, gallstones and later tuberculosis.

What do cancer, radiation, and technology have in common? The links between the three are quite extraordinary. Cancer is a disease that accounts for 13% of all deaths in the world (Delfino and Day 1). The disease has an impact on patients, friends and their love ones. According to WebMD, radiation is energy that travels in the form of waves through radiation therapy. Through radiation therapy, radiation is used to stop, slow or cure the growth of cancer. With technology, radiologists can treat cancer patients through radiation and special computerized imaging (WebMD).

A Spinal Cord Injury is damage to any part of the Spinal Cord nerves at the end of the Spinal Canal. Every Year, 17,000 Spinal Cord Injuries are reported in the USA alone. The Most Frequent age for Spinal Cord Injuries is 19. Almost 200 Spinal Cord Injuries were reported for High School Football. People who suffer from SCI (Spinal Cord injuries) can experience muscle weakness, poor coordination, and overactive reflexes.There is many

Spinal cord injuries can be extremely debilitating with significant impairment in autonomic, sensory, and motor function (Coll-Miro et al., 2016). The prevalence in Canada is on the rise with approximately 86,000 individuals suffering from such injuries as of 2010 (Noonan et al., 2012). Spinal cord injuries are generally classified as either traumatic or non-traumatic, depending on etiology (Sabapathy et al., 2015). In addition, they are subdivided into either complete or incomplete, depending on whether the spinal cord section is fully or partially damaged (Wilberger and Dupre, 2015). The latter classification has better clinical outcomes as some neurologic function is reserved (Wilberger and Dupre, 2015). Other subtypes include paraplegia and quadriplegia denoting paralysis of the lower body or all limbs, respectively (Wilberger and Dupre, 2015; Mayo Clinic Staff, 2014). The pathogenesis of spinal cord injuries is characterized by primary tissue damage due to the force of impact, followed by secondary tissue damage as a result of the inflammatory response (Sabapathy et al., 2015; Coll-Miro et al., 2015). The symptoms and severity may vary depending on the location and pathology of the contusion (Sabapathy et al., 2015). Presenting symptoms include but are not limited to numbness or pain in the extremities, loss of sensation, impaired movement or gait, abnormal reflexes, disrupted bladder or bowel function, and sexual dysfunction (Mayo Clinic Staff, 2014). Several

Spinal injuries can happen to anyone. There are less than 200,000 cases in the US each year, and most of the time this injury can not be completely cured. The spinal cord is about 18 inches long, it is a bundle of nerves which contains neurons that carry signals between the brain and body. The spinal cord has sections, C1-C8, T1-T12, L1-L5, the sacrum, and the coccyx. The C stands for Cervical, the T for Thoracic, and the L stands for Lumbar. Injuring different sections signifies different problems and diagnosis. The spinal cord controls the body. It controls sensory messages which include sense of touch, pain, pressure, temperature, and body position. It controls motor messages which tell the body what to do. For example, legs, arms, hands,

A cohort of mice underwent a second mTBI after 24 hours. Mice from both WT and Tg groups were assessed 2 days, 9 weeks, and 16 weeks after mTBI treatment. Primarily, H&E stain was employed along with Gomori’s iron stain to localize site and severity of mTBI injury. The degree of A deposition in the somatosensory cortex (SSC), the perihippocampal cortex (PHC), and the hippocampus (HP) of both hemispheres was determined by 4G8 immunostaining. In addition, GFAP staining was used to quantify the population of astrocytes at the site of the injury. Furthermore, Sandwich ELISA was utilized in mice groups 16 weeks after injury to measure A40 and A42 peptide levels in various brain regions, including the cerebral cortex, the hippocampus, and the cerebellum. Such tissues were also analyzed for isoprostane levels that are produced by lipid peroxidation. Isoprostanes were also detected in urine samples at various survival periods. Moreover, mice underwent Morison water maze (MWM) and composite neuroscore (NS) tests at 16 weeks’ post-injury to examine cognitive and motor functions respectively. Uryu and collegues found a significant increase in iron deposits and reactive astrocytes in the repetitive mTBI postmortem sections of Tg mice, when compared to other groups at 16 weeks after the injury. This was not the case in WT mice. Similarly, there was a significant increase in the A burden within select brain regions (i.e. SSC, PHC, HP) of single and

The central nervous system is responsible for controlling involuntary actions such as respiratory rhythm and blinking as well as voluntary actions such as muscular movements like walking. The central nervous system is composed of neurons that send and receive chemical messages through the transmittance of neurotransmitters. The spinal cord connects the brain to the body and when the spinal cord is damaged it loses its function to communicate messages from the brain throughout the body. Depending on the location and severity of the injury different symptoms and pathologies occur. There are different ways in which the spinal cord can be injured. It is protected by the spinal column, which is also called the backbone or spine. The spinal column is composed of a chain of bones called vertebrae, which are interconnected by flexible ligaments and spinal discs. However, if the spinal cord in injured and it starts to swell it starts to create pressure because the spinal column is surrounding it. Fractured bones of the spinal column or herniated discs can also cause damage to the spinal cord. The most common type of injury to the spinal cord is spinal cord compression when it is compressed due to a force on the spinal column. All of these different types of injuries lead to cell degeneration and death of the different types of cells in the spinal cord (Badner et al.

The limited space within the vertebrae actually plays an important roll in spinal cord injury. Once the initial injury occurs the body, as with every other part of the body, tries to protect the injured area with swelling. But the swelling occurs within the small confines of the spinal column and causes further damage to the surrounding tissue. It has only recently been discovered how much of an impact this secondary damage has. One of the areas of crucial ongoing research is on what kind of window of opportunity medicine has in treating these types of injuries and still attaining the best recovery.

The purpose of the experiment was to understand and determine the influence of Traumatic Brain Injury (TBI) on the spinal cord, and how the dietary Omega-3 (n-3) a fatty acid could counteract these effects. Not much is known about the effects of TBI on motor centers in the spinal cord. We are now starting to understand that TBI reduces the expression of some molecules that are critical for synaptic plasticity of the spinal cord.

X-rays were discovered by accident in 1895 by the German physicist Wilhelm Conrad Roentgen. Roentgen was already an accomplished scientist with forty-eight published papers. He had a reputation among the scientific community as a dedicated scientist with precise experimental methods. Roentgen had been conducting experiments at the University of Wurzburg on the effect of cathode-rays on the luminescence of certain chemicals. Roentgen had placed a cathode-ray tube, which is a partially evacuated glass tube with metal electrodes at each end, in a black cardboard box in his darkened laboratory. He sent electricity through the cathodre-ray tube and noticed something strange his laboratory. He saw a flash of light

Radiation therapy is the ionization of atoms in tissues resulting in formation of highly reactive radicals in a well-defined, restricted volume (1). In other words, ionizing radiations are used to eradicate tumors and at the same time preserve structure and function of normal tissue. A limitation is prevented from being a problem. If bone marrow or neuronal cells are destroyed or injured, they do not regenerate. However, with radiation therapy, these cells are often saved from injury or destruction, unless the tumor is infecting bone marrow or neuronal cells. Today, radiation therapy is the most popular type of cancer therapy in use. It is used to treat one-half to two-thirds of all cancers, which translates to more than ten percent of the population

The effects of radiation can be hazardous to any part of the human body. In this guide I will explain the advantages, and disadvantages of x-ray radiation. I will also discuss the technological advances that we have today then of what we had the past on the human body during radiation exposure. I will explain preventions of exposure and safety precautions that we as dental assistants as well as patients can follow to stay safe.

With this stability and mass production, x-rays machines became very common everywhere. From large factories, to doctors offices, all the way to the corner store of small towns, where children and adults alike could insert a coin into a machine and view the bones in their feet. (3.) Because of their relative adolescences in the world, not much was known about x-rays or their effects on the human body. The first theories about the rays’ effects on the human body were that they had beneficial applications. With this being the only theory about their effect, widespread use went on, unmonitored, and unregulated. This unregulated use led to injuries but because of their slow onset the injuries were never attributed to x-rays. While some scientists tied certain skin burns to over exposure of x-rays it wasn’t until popular minds of the world like Thomas Edison, Nikola Tesla and William J. Morton expressed that they experienced eye pain when dealing with the rays for extended periods of time that people began to connect the dots and understand the negative
