the interaction of radiation with cells and tissues has a random nature. therefore, understanding the random nature of cell killing that is determined by poisson distribution statistics is an essential point in education of radiation biology. radbiostat is a newly developed educational matlab-based software designed for computer-assisted learning of the target theory in radiation biology. altho...

The use of replication-competent viruses for the treatment of cancers is a rapidly growing area of research and offers an important strategy to specifically target tumor cells (1–5). A number of viruses, which can specifically infect cancer cells, have been explored in this context and have shown promising results. Identification of the optimal characteristics of such viruses is, however, a cha...

insulting to prophet or imam is obscene, shameful and insupportable for any muslim, so the person who insults must be killed. any where that there is no islamic government or it has not been ordained any rule about killing insulter; killing insulter has no retaliation (punishment). but when legislator especially issued a rule for killing punishment in article513 for the crime of insulting to pr...

One of the most challenging problems in microbiology is to understand how a small fraction of microbes that resists killing by antibiotics can emerge in a population of genetically identical cells, the phenomenon known as persistence or drug tolerance. Its characteristic signature is the biphasic kill curve, whereby microbes exposed to a bactericidal agent are initially killed very rapidly but ...

A widely held tenet of present day oncology is that tumor cells treated with anticancer agents die from apoptosis, and that cells resistant to apoptosis are resistant to cancer treatment. We suggest, in this review, that this tenet may need to be reexamined for human tumors of nonhematological origin, for two principal reasons: (a) cell killing has often been assessed in short term assays that ...

1. Investigations were made into the breast and leg muscle energy metabolism, and the quality of breast meat of turkeys after controlled atmosphere stunning or stun-killing (CAS) with various gas mixtures. In addition, the effect on meat quality of an increase in the chilling rate of turkey breast meat after hypercapnic or anoxic stun-killing was studied. 2. A total of 35 turkey toms within t...
