flora in the nasopharyngeal area. However, when the host immune mechanism is weak, it can gain access to the meninges. The invasion of the meninges usually happens when N. meningitidis enters the bloodstream which leads the organism to reach the Cerebrospinal
Organism Naegleria fowleri, the brain eating amoeba, exists around the world; reservoirs of N fowleri include sediments of lakes, rivers, geothermal water, soil, and poorly kept swimming pools. These microbes can live in temperatures up to 45 degree Celsius and do not require a host cell for survival. The free-living amoeba is the etiological source of primary amoebic meningeocephalitis (PAM), an acute and fatal disease of the central nervous system with fatality rates over 99%. Onset of illness
in less common cases, meningitis can possibly be caused by certain medications or injuries. The most common way that meningitis is contracted is by bacteria or viruses that infect the body and spread from the bloodstream to the meninges by cerebrospinal fluid. Viral meningitis is more frequently seen and is not usually severe. In more serious cases, viral meningitis may cause prolonged fever or seizures. On the other hand, bacterial meningitis is very serious and must be treated immediately in order
Hydrocephalus is a genetic disorder commonly described as “water on the brain.” In actuality, this is a condition in which there is an excessive accumulation of cerebrospinal fluid (CSF), a clear watery fluid that surrounds the space between the brain and spinal cord, in the brain. Normally, the production together with the absorption process of CSF is specifically balanced to ensure that the brain tissue remains buoyant, that nutrients can be delivered and waste removed, and that there is a compensation
is a result of escalated brain cell death. During the examination of the MRI scan of affected infants, the speaker observed brain minimal convulsions, malformation of the cerebral cortex, intracerebral calcification, an increased amount of cerebrospinal fluid (CSF) in the cerebellum and indicators of spastic quadriplegia ( a severe form of cerebral
Meningitis is an inflammation of the meninges, which are the membranes that cover the brain and spinal cord. The disease can be caused by a viral, bacterial, fungal or parasitic infection. Viral meningitis is the most common cause of this disease, yet it’s rarely fatal and can improve without the need of treatment. In the United States, bacterial meningitis continues to be a significant source of morbidity and mortality. Early diagnosis and treatment of meningitis can be the line between life and
affiliated with excessive fluid in the brain. Causes, incidence, and risk factors The fluid in the brain (cerebrospinal fluid or CSF) is formed in the brain. CSF usually circulates through parts of the brain, its covering, and the spinal canal, and is then absorbed into the circulatory system. When the circulation or absorption of this fluid is blocked, or excessive fluid is produced, the volume of fluid in the brain becomes higher than normal. The accumulation of fluid puts pressure on the brain
This proposal focuses on defining a cell-based therapy aimed at treating hydrocephalus and on limiting the immune response that is a common problem in hydrocephalus treatment as the shunt’s ventricular catheter becomes obstructed with tissue. This novel approach was designed after a literature review of contemporary and previously proposed treatment plans to identify if a personalized cell-based therapy can be implemented and result in improved patient outcomes. General Background: The word
Meningitis, it’s an infection in the cerebral spinal fluid and inflammation of the meninges; the three outer layers of the brain. To be more specific, those three layers are called the Dura mater, Arachnoid mater, and the Pia mater. There are three main types of meningitis that will be discussed throughout this paper; viral, bacterial, and fungal. Each form is very similar but they all vary in terms of causative organisms, treatment and severity. Although meningitis is not very common, it can become
Meningitis is a bad disease that effects the muscles in the back and neck as well as effecting the immune system. This research paper should give all of the information that a person should need to know about all types of meningitis. This is a research paper about meningitis, and how it is transmitted, how it effects victims, and the treatment for it. Meningitis is the infection of the meninges. It is caused most commonly by bacterial or viral infection, and may be caused by fungal infection, or
Meningitis is a disease caused by the inflammation of the protective membranes covering the brain and spinal cord known as “meninges”. The inflammation is usually caused by an infection of the fluid surrounding the brain and spinal cord. There are several types of meningitis. The most common is viral meningitis, which you get when virus enters the body through the nose or mouth and travel to the brain. Bacterial meningitis is rare, but can be deadly. It usually starts with bacteria that cause a cold-like
Spina bifida, which literally means “cleft spine,” is characterized by the incomplete development of the brain, spinal cord, and/or meninges, the protective covering around the brain and spinal cord. Meningomyelocele is the most severe type Spina Bifida, and requires surgery as treatment. It happens when parts of the spinal cord and nerves come through the open part of the spine. It causes nerve damage and decreased motor function. . Despite aggressive intervention, nearly 14% of all Spina Bifida
Meningitis is an inflammation of the meninges, which are membranes covering the brain and spinal cord. Meningitis can be caused by infections from viruses, bacterium, or other microorganisms. Due to the inflammation being in close proximity to the brain and spinal cord, meningitis can be life threatening and is classified as a medical emergency. The first recorded major outbreak of meningitis occurred in 1805, even though many scientists suggest that Hippocrates was the first to discover the existence
impulses by connection the axon to the dendrites of another nerve cell. The synapse is a gap between the axon and the adjacent neuron, which is where data is transmitted from one neuron to another. The neuron is negatively charged and it bathes in fluids that contain positively charged potassium and sodium ions. The membrane of the neuron holds negatively charged protein molecules. The neuron has pores called ion channels to allow sodium ions to pass into the membrane, but prevent the protein molecules
and medical facilities are screening blood more thoroughly. Even though HIV ( Human Immunodeficieny Virus) can be transmitted through sharing of non sterilize needles and syringes, sexual intercourse, blood transfusion, and through most bodily fluids, it is not transmitted through casual contact or by biting or blood sucking insects. Development of the AIDS Epidemic The first case of AIDS were reported in 1982, epidemiologists at the Center of Disease Control immediately began tracking
you need to warm one gram of most other fluids by the same amount. This makes water much better for regulating the temperatures of animals and the environment. Water also has a very high heat of vaporization. Converting one gram of cold water into ice requires 80 Calories of energy. Converting the same amount of very hot water into steam requires 540. The high amounts of energy required to change water from its liquid state make water tend to stay a fluid. The process of freezing water involves slowing
everyday situations, such as deciding how much fencing is needed to encompass a designated area. Finding how gravity affects certain objects is how calculus aids people who study Physics. Mechanics find calculus useful to determine rates of flow of fluids in a car. Numerous developments in mathematics by Ancient Greeks to Europeans led to the discovery of integral calculus, which is still expanding. The first mathematicians came from Egypt, where they discovered the rule for the volume of a pyramid
stands for dilation and evacuation. These are preformed up to the twenty-fifth week of pregnancy, and usually take ten to twenty minutes. The way they are preformed is the woman is given absorbent dilators, which open up the cervix and absorb the fluids. After this is left in overnight the woman then is ready for the evacuation stage. The fetus is easily removed with instruments and suction. In the last trimester of the pregnancy abortions are preformed mainly if the woman’s life is in danger or

The ORAC assay – a brief introduction 2.1 Theoretical background The oxygen radical absorbance capacity (ORAC) assay is a method for measuring the total antioxidant activity in a biological sample. Biological samples include body fluids of animals and humans (serum, plasma, urine, saliva), plant extracts, agricultural and food products, and pharmaceutical products.[6] The advantage of the ORAC assay is the wide range of applications as it can be used for both lipophilic and hydrophilic
Filovirus, and that is Marburg. Ebola has a 90% death rate, whereas, Marburg is not as deadly. Their long and ropelike shape rather than roundness, as is most other viruses, characterize Filoviruses. Ebola is contracted very much like HIV: bodily fluids such as blood, vomit, sharing needles, and sexual contact. The only difference is that Ebola can be transmitted from the close contact of an infected person, which is the most common means of infection. This is possible because the Ebola virus has
