Thesis: The multi-electrode array (MEA) is the greatest breakthrough in neuroscience today because it will lessen millions of people’s pain dramatically‚ it will spare millions of animals from cruelty and death‚ and it will cure millions of people and animals from paralysis. I. People’s chronic neurological pain will be reduced because of the ability of MEAs above any other breakthrough in neuroscience today. A. While there are many treatments in the world that alleviate the suffering of neurological

INFECTION CONTROL Pathogen- Infectious agent Colonization- If microorganism is present or invades host‚ grows and/or multiplies but does not cause infection. Communicable disease- if infectious disease can be transmitted from one person to another. -Symptomatic-if pathogens multiply and cause clinical signs/symptoms. -Asymptomatic- if no s/s are present *CHAIN OF INFECTION: 1. An infectious agent or pathogen 2. A reservoir or source for pathogen growth 3. A portal of exit from the

Epidemiology – the science that studies when and where diseases occur and how they are transmitted. CDC‚ Atlanta‚ tracks and traces diseases.

Clostridium difficile is a major problem that is a growing concern in health care treatment facilities. Clostridium difficile is a type of bacterial infection that affects the intestines. Clostridium difficile is not really an infection‚ it is a very obnoxious bacteria. Clostridium is a bacterium that someone gets when their immune system is weak. Each year‚ more than half a million people get sick from Clostridium difficile‚ and Clostridium difficile has become very difficult to treat‚ severe‚ and

creates the bacteria Clostridum tetani. The bacterium produces a toxin which can harm the nervous system and the brain. Excessive muscle spasms also come along with the disease‚ and these occur most often in the neck and jaw area. The spasms in the neck and jaw area can lead to respiratory issues. There is a lot of information you should know about Tetanus in order to remain free from this fatal disease. Characteristics:

INFECTION An infection is the colonization of a hostorganism by parasitespecies. Infecting parasites seek to use the host’s resources to reproduce‚ often resulting in disease. Colloquially‚ infections are usually considered to be caused by microscopic organisms or microparasites like viruses‚ prions‚ bacteria‚ and viroids‚ though larger organisms like macroparasites and fungi can also infect. Hosts normally fight infections themselves via their immune system. Mammalian hosts react to infections

that the bacteria do not actually “eat” the tissue. They cause the destruction of skin and muscle by releasing toxins‚ which include streptococcal pyrogenic exotoxins. It is a rare bacterial infection that invades the skin and tissues under the skin. (Asttrino 1). The tissues die rapidly‚ so it is important for doctors to catch it early. This disease increases sensitivity‚ releases toxins‚ increases the permeability of the vessels‚ inhibits blood supply. There are several stages of necrotizing fasciitis

Food Packaging Food packaging draws on disciplines like chemistry‚ microbiology‚ food science and engineering. About 25% of the ex-factory cost is for packaging and thus provides the challenge for food packaging technologists to design and develop functional packages at low cost. Today packaging is pervasive and essential. It surrounds‚ enhances and protects the goods from processing and manufacturing through handing and storage to final consumption without packing‚ materials would be messy

aureus has touched. Staphylococcus aureus is coagulase positive‚ which induces clumping of the cells and of the blood. Staphylococcus aureus has many immune-evasive strategies that make it the most common strand‚ such as; it produces leukocidin a toxin that kills white blood cells. It also resists opsonization‚ survives in phagolysosomes‚ and is lysozyme resistant. Methicillin-resistant S. aureus‚ abbreviated MRSA‚ is one of a number of greatly feared strains of S. aureus‚ which have become resistant

NOTES ON FOOD PRESERVATION & PACKAGING FOR MSc STUDENTS By Prof C S Purushothaman – Feb 2013 HURDLE TECHNOLOGY The spoilage and poisoning of foods by micrnorgenisms is a problem that is not yet under adequate control‚ despite the range of preservation techniques available (e.g. freezing‚ blanching‚ pasteurizing and canning). In fact‚ the current Consumer demand for more natural and fresh-like foods‚ which urges food manufacturers to use only mild preservation techniques (e.g. refrigeration‚ modifed-atmosphere
