Photosynthesis - Factors. 1  There are three main factors affecting photosynthesis and several corollary factors. 2  Light irradiance and wavelength. 3  Carbon dioxide concentration. 4  Temperature.
Indolent B-cell lymphomas that are supposed to derive from the marginal zone (marginal zone lymphomas) include three specific entities: extranodal marginal zone lymphoma or mucosa-associated lymphatic tissue (MALT) lymphoma, splenic marginal zone lymphomas (SMZLs), and nodal marginal zone lymphomas (NMZLs).
MALT stands for mucosa associated lymphoid tissue. This means that the lymphoma starts in the mucosa. The mucosa is a moist tissue that lines body organs and cavities including your nose, mouth, lungs, and digestive system. So, MALT lymphoma starts in the body organs and not in the lymph nodes.his means that the lymphoma starts in the mucosa.
