Mycobacterium vaccae Lysate Induces Anti-Allergic Immune Response In Vitro.

Mycobacterium vaccae is a soil saprophyte which exerts anti-allergic properties. There are data that mechanism of action of M. vaccae when used in the treatment of human and animal allergic diseases is associated with Th1-phenotype switch.

ZO-1 expression shows prognostic value in chronic B cell leukemia.

Connexin-mediated gap junctions are vital for tumor cell function. Intracellular pathways of connexin signaling use Zonula Occludens protein-1 (ZO-1) as an intermediate. This report describes the ZO-1 and connexin 43 (Cx43) expression pattern in lymphocytes from chronic B-cell leukemia (B-CLL) patients.

[Detection of viral infection markers by radioimmunoassay on flat nonporous fluorosorbents].

The authors present a new variant of radioimmunoassay (RIA) for the detection of markers of viral infections, based on the use of plane nonporous fluorosorbents with organic fluorochromes. An advantage of this method is its fitness to use of not only 125I, but of 3H-ligands as well, for both the indicators may be counted on the fluorosorbent in a standard beta-scintillator in dry flasks without liquid scintillator. The possibility of using 3H makes this method safe.
