B-lymphocyte antigen CD20 or CD20 is B lymphocyte cell-surface molecule. It is a 33-37 kDa non-glycosylated protein. CD20 is expressed on the surface of B-cells from the pre-B phase, the expression is lost in terminally differentiated plasma cells. [5] [6] CD20 is used as a therapeutical target of B-cell malignancies and autoimmune diseases. [6]
Splenic B-cell lymphoma/leukemia unclassifiable: The rare reports on this lymphoma find the monoclonal B cells to be CD19+, CD20+ (bright, CD23+, CD11+, CD25−, CD103−, CD72+, and annexin A1−. [18] These cells, similar to the monoclonal cells in Hairy cell leukemia, [19] may have the V600E mutation in the BRAF gene. Patients with this ...
Substances with molar mass below 1000g/mol (e.g. electrolytes and metabolites) would have "negative" distance, that is, masses deviating to the left. Many substances given in mass concentration are not given in molar amount because they haven't been added to the article.
Unlike classic RSC, the non-classic popcorn-shaped RS cells of NLPHL are CD15 and CD30 negative while positive for the B cell marker CD20. The anti-CD20 monoclonal antibody Rituximab has been used in lymphocyte predominant Hodgkin lymphoma with encouraging results. [6] BCL6 gene rearrangements have been frequently observed. [7] [8]
Milk allergy is an adverse immune reaction to one or more proteins in cow's milk.Symptoms may take hours to days to manifest, with symptoms including atopic dermatitis, inflammation of the esophagus, enteropathy involving the small intestine and proctocolitis involving the rectum and colon. [2]
On average, whole milk contains 3.25% fat—only a few percentage points higher than low-fat milk. To broaden your perspective, half-and-half can contain up to 18% fat, while heavy cream must be ...
Litmus milk is a milk-based medium used to distinguish between different species of bacteria. [ 1 ] [ 2 ] The lactose (milk sugar), litmus (pH indicator), and casein (milk protein) contained within the medium can all be metabolized by different types of bacteria.
Of that weight, 2% milk holds 5 grams of fat and whole milk contains 8 grams. So whole milk isn't much fattier than 2%. In fact, a gallon of 2% has more than half the fat as a gallon of whole milk.
