Duckweeds are of special interest, as they are naturally growing weeds that have the capacity to tolerate and remove toxic pollutants, including heavy metals from the environment. Studies have revealed that duckweed (Lemna minor) can tolerate and remove heavy metals from aqueous solutions. In the present study, the efficiency of L. minor in the removal of Ni and Cr individually from aqueous sol...
Infection by the influenza virus depends firstly on cell adhesion via the sialic-acid-binding viral surface protein, haemagglutinin, and secondly on the successful escape of progeny viruses from the host cell to enable the virus to spread to other cells. To achieve the latter, influenza uses another glycoprotein, the enzyme neuraminidase (NA), to cleave the sialic acid receptors from the surfac...
BACKGROUND Antibiotic resistance has become one of the major problems facing humanity. The need for new antimicrobials has been increased dramatically. Plants are considered as one of the most promising sources for new antimicrobials discovery. Despite relatively small area, Armenia has large diversity of flora with many endemic species. In Armenian folk medicine plant materials have been used ...
Classification of bacterial viruses: characteristics of the T1,D20 species of coli-dysentery phages.
Coliphage Ti of Demerec and Fano (1945) has been found to be closely related serologically to dysentery phage D20 of Burnet (1933). A comparative study of the properties of these two phage strains has been made in order that the distinctive characteristics of the T1,D20 species may be better defined. It is unfortunate that of a large number of enteric phages studied, these two were the only str...
We are witnessing a significant challenge to immunology's basic tenet, the immune self. Such an 'entity' is increasingly regarded as polymorphous and ill defined as transplantation biology and autoimmunity have demonstrated phenomena that fail to allow faithful adherence to a strict dichotomy of self/nonself discrimination. Instead of searching for elusive criteria of 'self' and 'other', immune...
