The human cytomegalovirus (HCMV) proteinase is synthesized as a 709-amino-acid precursor that undergoes at least three autoproteolytic cleavages. The mature proteinase, called assemblin, is one of the products of autoproteolysis and is composed of the first 256 amino acids of the precursor. HCMV assemblin and its homologs in other herpes group viruses contain five highly conserved domains (CD1 ...

zki (1993) noted that genetic engineering in sugarcane would be a useful tool for reversing single flaws, such Genetic transformation of sugarcane (Saccharum spp.) holds promas disease susceptibility, in commercial cultivars. Sugarise for increasing yields and disease resistance. However, the tissue cane may benefit from genetic transformation because its culture and transformation process may ...

In the treatment of superficial lesions with 8-13 MeV electrons, lead shields are often used to protect the underlying tissue. Measurements were made with film and ion chamber to analyse various aspects of external and internal shielding in electron beam therapy. Data were obtained on the thickness of lead required for shielding, the effect of blocking on dose-rate, electron-backscattering from...
