What is reactive plasma disease?
Reactive plasmacytosis is a rare event found in a variety of diseases such as infectious diseases, tumors and autoimmune disorders [20]. Reactive plasmacytosis has been reported in several types of virus infections including Hepatitis A virus, Epstein-Barr virus, Dengue virus, Parvovirus B 19 [21,22,23,24].
What is the difference between ICP and RIE?
ICP-RIE technology ICP-RIE etching is based on the use of an inductively coupled plasma source. The key differentiation between ICP RIE and RIE is the separate ICP RF power source connected to the cathode that generates DC bias and attracts ions to the wafer.
What is RIE used for?
Reactive ion etching (RIE) is a type of plasma etch technology used in specialty semiconductor markets for device manufacturing. Chemically reactive species (ions) are accelerated toward the substrate (usually a silicon wafer), to remove a specific deposited material.
What does plasmacytosis mean?
(PLAZ-muh-sy-TOH-muh) A type of cancer that begins in plasma cells (white blood cells that produce antibodies). A plasmacytoma may turn into multiple myeloma. Enlarge. Blood cell development.
What causes reactive Plasmacytosis?
There are many causes of reactive bone marrow plasmacytosis including infection, malignancy, inflammation, Castleman’s disease, iron deficiency, megaloblastic anaemia, haemolytic anaemia, diabetes mellitus, cirrhosis,5 and streptokinase treatment.
Is plasma cell leukemia the same as multiple myeloma?
Plasma cell leukemia is clinically and genetically distinct from multiple myeloma. Plasma cell leukemia is defined by the observation in blood of more than 20% clonal plasma cells by differential count of the leucocytes or by counting more than 2 × 109 per liter circulating clonal plasma cells.
What is meant by reactive etching?
Reactive-ion etching (RIE) is an etching technology used in microfabrication. RIE is a type of dry etching which has different characteristics than wet etching. RIE uses chemically reactive plasma to remove material deposited on wafers. High-energy ions from the plasma attack the wafer surface and react with it.
Is RIE anisotropic or isotropic?
RIE is based on a combination of chemical and physical etching which allows isotropic and anisotropic (uni-directional) material removal.
Which gas is used in RIE?
Other gases used in RIE include oxygen, hydrogen, argon, helium and nitrogen. These have roles in modifying plasma chemistry and physics, heat transfer and surface chemistry.
What is dry and wet etching?
The two basic types of etching agents are the liquid phase and the plasma phase. The etching process of using liquid chemicals or etching agents to remove material from the substrate is called wet etching. Dry etching produces gaseous products, which must diffuse into the bulk gas and be expelled by the vacuum system.
Is plasmacytoma curable?
Solitary plasmacytoma of the bone can sometimes be cured with radiation therapy or surgery to destroy or remove the tumor. However, 70 percent of people with solitary plasmacytoma eventually develop multiple myeloma. They then need additional treatment, such as chemotherapy.
What is a plasma cell neoplasm?
Plasma cell neoplasms are diseases in which the body makes too many plasma cells. Plasma cells develop from B lymphocytes (B cells), a type of white blood cell that is made in the bone marrow. Normally, when bacteria or viruses enter the body, some of the B cells will change into plasma cells.
What do you need to know about rapid plasma reagin?
The rapid plasma reagin (RPR) test is a blood test that looks for antibodies to syphilis. Syphilis is a sexually transmitted disease (STD) that first causes symptoms common to many other illnesses.
What’s the plasma half life of C reactive protein?
However, some healthy adults show elevated CRP at 10 mg/L. When there is a stimulus, the CRP level can rise 10,000-fold from less than 50 μg/l to more than 500 mg/L. Such levels can rise to 5 mg/L by 6 hours and peaks at 48 hours. The plasma half-life of CRP is 19 hours.
What does a negative plasma reagin result mean?
A negative or nonreactive result means you don’t likely have syphilis. Positive results are given as a ratio in titers. This tells your healthcare provider the amount of antibodies in your blood. Here are some general results:
What does a C reactive protein test show?
It measures the level of C-reactive protein (CRP) in your blood. This type of test can be performed in both adults and children, and even babies to check for signs of illnesses. Changes in CRP levels can indicate whether or not treatments you’re receiving are working to manage inflammation.
