M components and cancer

M MunzarováA Kubíková-Kourilová


Intention of this study was to prove or exclude in patients with different neoplasms some M components which can escape routine electrophoretic analysis or immunoelectrophoretic analysis with polyvalent antiserum. All serum samples from 606 patients were investigated also with monospecific antisera against heavy chains--alpha, gamma, mu and delta--and in suspicion of abnormality also with antisera against light chains. Patterns similar to those found in cases of heavy chain diseases were absent in all patients. M components of IgD class were not found, as well. As to M components of usual types a relatively high incidence was found in lymphoproliferative malignancies excluded myelomas or Waldenstroöm's macroglobulinemias (5.61% in adults and 2.32% in children). On the basis of results the importance of immunoelectrophoretical analysis with monospecific antisera in all these cases is pointed out; not only in attempt to discover additional subjects of heavy chain diseases but also to detect mild "macroglobulinemic" abnormalities which may not be so far detected on electrophoretical pattern.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Central Pontine Myelinolysis

Central Pontine Myelinolysis is a neurologic disorder caused most frequently by rapid correction of hyponatremia and is characterized by demyelination that affects the central portion of the base of the pons. Here is the latest research on this disease.

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

Pontocerebellar Hypoplasia

Pontocerebellar hypoplasias are a group of neurodegenerative autosomal recessive disorders with prenatal onset, atrophy or hypoplasia of the cerebellum, hypoplasia of the ventral pons, microcephaly, variable neocortical atrophy and severe mental and motor impairments. Here is the latest research on pontocerebellar hypoplasia.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain. Disocver the latest research on single cell analysis of the gut-brain axis here.

Chronic Traumatic Encephalopathy

Chronic Traumatic Encephalopathy (CTE) is a progressive degenerative disease that occurs in individuals that suffer repetitive brain trauma. Discover the latest research on traumatic encephalopathy here.
