چکیده

Guanidine does not inhibit the translation of viral RNA into virus specific proteins but it seems to prevent the generation of functional viral polymerase from precursor material. In the presence of guanidine, "inhibitory protein (s) " responsible for the shut-off of cellular protein synthesis are still produced provided that the multiplicities of infection are high. The incoming (parental) viral RNA appears to be functional as messenger for only a limited number of translational cycles.

Dipyridamole reversibly inhibits mengovirus RNA replication.

Dipyridamole is an effective inhibitor of cardiovirus growth in cell culture. The effects of dipyridamole on mengovirus replication in vivo and in vitro were examined in the hope the drug could be used as an experimental analog of the poliovirus inhibitor guanidine. Guanidine selectively inhibits poliovirus RNA synthesis but not RNA translation, and as such, has been a valuable research tool. A...

Guanidine-sensitive Na+ accumulation by poliovirus-infected HeLa cells.

The Na+ content of poliovirus-infected HeLa S3 cells increased during the late phase of virus replication, after virus inhibition of host cell protein synthesis and in coincidence with late viral functions. Guanidine hydrochloride blocked the rise in Na+ content, whereas the antiguanidine agent choline fully reversed the guanidine block. Expression of one or more late viral functions was essent...

Random regression models for estimation of covariance functions of growth in Iranian Kurdi sheep

Body weight (BW) records (n=11,659) of 4961 Kurdi sheep from 215 sires and 2085 dams were used to estimate the additive genetic, direct and maternal permanent environmental effects on growth from 1 to 300 days of age. The data were collected from 1993 to 2015 at a breeding station in North Khorasan province; Iran. Genetic parameters for growth traits were estimated using random regression test-...

Comparison of Captopril with Enalapril on Improvement of Systolic and Diastolic Heart Functions in Asymptomatic Patients Over 10 Years Old with Beta- Thalassemia Major

Background: Beta-thalassemia major is a severe and lethal hemolytic anemia. Regular transfusion is necessary for avoidance of its complications but it may end to cardiac involvement secondary to iron overload. Angiotensin converting enzyme inhibitors (ACEIs) are useful medications even in early stages of heart failure. We studied the effects of two common ACEIs on improvement of heart function ...

Acquiring molecular interference functions of X-ray coherent scattering for breast tissues by combination of simulation and experimental methods

Background: Recently, it has been indicated that X-ray coherent scatter from biological tissues can be used to access signature of tissue. Some scientists are interested in studying this effect to get early detection of breast cancer. Since experimental methods for optimization are time consuming and expensive, some scientists suggest using simulation. Monte Carlo (MC) codes are the best...
