Pathology
Pathology is the scientific study of the nature of disease and its causes, processes, development, and consequences. It deals with the study of mechanisms and manifestations of disease, and involves the study of bodily changes that occur as the result of disease. This category is for questions about pathology, the study of disease and its causes, development, and consequences.

What are the pros and cons of water energy?
Water as an energy source has been used for thousands of years. The primary example is the grinding of corn. It is a potential source of all our energy needs.
A few of the PROS of water energy
- Wave and tidal energy is a source that is constantly available.
- Tidal turbines are located on the ocean floor - don't obstruct scenery.
- Wave energy plants divert some of the energy away from the shore causing less damage to the shoreline and recreational beaches.
- Wave energy is more efficient than wind energy.
- Geothermal hot springs/geysers and underground reservoirs have a huge potential of "clean" energy for the US.
- Iceland is a prime example of geothermal and hydropower usage.
- New technology has produced hydropower turbines which don't affect fresh-water fish and don't need dams.
- Water energy is clean renewable green energy.
- Once established, the cost stays constant (fixed cost) and the water is free.
- Dams also create recreational areas and fish breeding sites.
- The set-up takes money that the government has not allocated.
- Wave/Tidal turbines - will they affect marine life, if at all.
- Wave converters may break down frequently causing loss of service.
- Hydroelectric power: cost of building dams, flooding upstream, affect on human, plant and animal populations, downstream changes can affect quality of water and its affect on animal/plant life.
- Dams do destroy the previous environment while producing a new one. During the change over, trees will decay emitting greenhouse gases.
- It takes a lot of water to create energy, though scientists are working on new turbines to reduce the amount needed.
its not cheap but ecologic
What can you do with a master's degree in forensic pathology?
how to became a forensic patologist
You can also decide to go to medical school and become a medical examiner.
Working with dead people is so much easier than working with the live ones. Less back talk.
What is the difference in Pathology and Morbidity?
Pathology is the study or diagnosis of disease.
Morbidity is a state of ill health, disease or disablement from a specific source.
What method is used by the physician to obtain a lesion biopsy depends on which set of factors?
size and type
When must an autopsy be preformed?
An autopsy must be performed when there is uncertainty about the cause of death, especially in cases of sudden, unexplained, or suspicious deaths. It is also required in instances of deaths due to violence, accidents, or when a death occurs in custody. Additionally, autopsies may be mandated by law for public health investigations or when the deceased's identity is unknown. Ultimately, the decision often involves legal and medical authorities.
What colleges are known for speech pathology?
University of Iowa, Northwestern, and Arizona State are "known" for speech pathology. When looking at a Master's Degree program, it is good to look at the program's course of study, the interest areas of the professors, and the areas of research that the department has produced to see if these are areas of interest for the prospective student. When I am hiring an SLP, it matters little to me where the person went to school. I just want to be sure that they are excellent clinicians.
Why is my groin aching after biopsy procedure?
The needles used to take the biopsy can leave a soreness that may last a couple of days.
What are hyperchromatic nuclei?
A hyperchromatic nucleus (plural, nuclei) is a nucleus that takes up more stain than expected on a slide. It can be an indication of over-active nuclear function, which may be an early indication of either cancerous changes or of a cell that is responding vigorously to damage or other stimulus.
What effect does helicobacterium pylori has on stomach?
It is one of the main causes of stomach ulcers.
Which organism is involved in sinusitis?
Like most infectious diseases, sinusitis is caused by a variety of bacteria, as well as viruses, fungi, foreign bodies and autoimmune disease.
If prostate enlargement has been ruled out and the urinalysis shows no infection or cancer, the next place I would look is the nervous system that controls the bladder. There are some neurodegenerative diseases that can show signs like difficulty releasing urine.
What classes taken for speech pathology?
Speech therapists examine, diagnose and treat patients with speech disorders. Classes they must take include Speech and Language Acquisition Course, Speech Anatomy and Physiology Course, and Speech Therapy and Phonetics Course, to name a few.
What is the aftercare for a liver biopsy?
Immediately after the biopsy, pulse, respiration, and temperature (vital signs) are measured. If they are stable, the patient is instructed to lie flat in bed for at least 12 hours. The pulse and blood pressure are checked at regular.
What are the Importance of plant pathology in human life?
A plant pathologist studies plant diseases and insect infestations on crops. Their work is relevant in understanding how and why various crops are attacked by insects and pests (fungi, bacteria and viruses) and how to minimise the economic effect (of attacks) on commercial crops by these pathogens.
Pathology also encompasses the study of plant chemistry to ensure that crops (food as well ornamental) are well fertilised and are not deficient in nutrients. Poorly nourished crops are more susceptible to attack from insects, fungi and bacterial infections.
What is a biopsy mean in the antrum?
A biopsy is when tissue is taken from a site on or in the body for further study. This further study is for diseases or disease processes that may be forming. A biopsy of the antrum is most likely where a small amount of tissue is taken from the antrum of the stomach to be tested.
One way is to perform your lab exams on a frozen section -- the other is to use a permanent section of the specimen. A permanent section uses a fixative, like wax or some chemical, to hold the tissue together for analysis by the pathologist.
What does it mean is most likely secondary to a variant of normal hepatic perfusion?
This is a phrase you probably found in a doctor's chart or pathology report somewhere. The term "secondary" means "as a result of some other process or finding". The phrase "variant of" means "an unusual but not abnormal or disease-causing condition". "Normal hepatic perfusion" is the typical pathway which blood vessels bring blood into and out of the liver.
Putting all the pieces together, "most likely secondary to a variant of normal hepatic perfusion" means this finding was probably caused by a slightly different way that the blood vessels in the liver hooked up and branched out. You would have to consult with your doctor to be sure, but this doesn't sound like a severe problem at this time.
What does level IV surgical pathology gross and microscopic exam mean?
Level IV surgical pathology gross and microscopic exam includes biopsies. These biopsies are studied by several different doctors of medicine to rule out malignancy.
Skin biopsies are usually brief, straightforward procedures performed by a skin specialist (dermatologist) or family physician.
Can an autopsy be performed against the wishes of the family of the deceased?
Yes, absolutely it can, but it depends on the circumstances. If there is any reason to doubt the cause of death, then yes. If the person is old and there is an obvious cause of death that no one questions, then it probably won't happen, but the family's wishes are definitely not considered more important than solving a homicide, for instance.
Blood is made up of four main parts. These are: Red blood cells. These are nuclei-less cells packed full of haemoglobin to carry oxygen around the body. White blood cells. These are the immune system of the body, and protect the body from any invading pathogens.
Platelets. These are the cells that form scabs and clots when you get cut.
Plasma. This is the liquid part of the blood, and makes up around 60% of the blood content.
