CREST syndrome, also known as the limited cutaneous form of systemic sclerosis (lcSSc), is a multisystem connective tissue disorder. The acronym "CREST" refers to the five main features: calcinosis , Raynaud's phenomenon , esophageal dysmotility , sclerodactyly , and telangiectasia .
Seroconversion. In immunology, seroconversion is the development of specific antibodies in the blood serum as a result of infection or immunization, including vaccination. [1] [2] During infection or immunization, antigens enter the blood, and the immune system begins to produce antibodies in response.
Immunodeficiency. Immunodeficiency, also known as immunocompromisation, is a state in which the immune system 's ability to fight infectious diseases and cancer is compromised or entirely absent. Most cases are acquired ("secondary") due to extrinsic factors that affect the patient's immune system. Examples of these extrinsic factors include ...
It's offering free samples of Crest Whitestrips. First impressions are everything, you know. You want a smile that's clean and white. But those Zoom treatments are a little pricey for this economy ...
A unique, individual set of antibodies, called individual specific autoantibodies (ISA), is found in blood, serum, saliva, urine, semen, perspiration, tears, and body tissues, and the antibodies are not affected by illness, medication, or food/drug intake. An unskilled technician using inexpensive equipment can complete a test in a couple of hours.
In immunology, passive immunity is the transfer of active humoral immunity of ready-made antibodies.Passive immunity can occur naturally, when maternal antibodies are transferred to the fetus through the placenta, and it can also be induced artificially, when high levels of antibodies specific to a pathogen or toxin (obtained from humans, horses, or other animals) are transferred to non-immune ...
Immunoglobulin A ( Ig A, also referred to as sIgA in its secretory form) is an antibody that plays a role in the immune function of mucous membranes. The amount of IgA produced in association with mucosal membranes is greater than all other types of antibody combined. [ 3] In absolute terms, between three and five grams are secreted into the ...
Cellular immunity, also known as cell-mediated immunity, is an immune response that does not rely on the production of antibodies. Rather, cell-mediated immunity is the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen. [ 1]
