Antisense oligonucleotides have the potential to make revolutionary contributions to basic science and medicine. Oligonucleotides can bind mRNA and inhibit translation. Because they can be rapidly synthesized to be complementary to any sequence, they offer ideal tools for exploiting the massive amount of genome information now available. However, until recently, this potential was largely theor...

This study investigated the awareness and attitudes of basic surgical trainees. Trainees were asked to answer questions from a pre-set questionnaire. Fifty basic surgical trainees from England and Wales were involved in the study. The areas covered were basic knowledge of radiation hazards, use of protective wear, pregnancy test in female trauma victims of reproductive age, and principles of sa...

Background: Ionizing radiation causes deleterious effects on living system mainly due to oxidative damages of macromolecules and protein is the major target due to its abundance. The aim of this study was to investigate the effects of ionizing radiation induced changes in the molecular properties of bovine serum albumin (BSA) its secondary and tertiary structures, degradation, cross linking and...

Transition radiation is emitted when a relativistic charged particle crosses the boundary between two media of different dielectric properties. Radiation is also produced if the particle does not cross the discontinuity directly but passes it at such a close distance that its self-field is modified by the sudden change in the dielectric constant. In this case one speaks of diffraction radiation...

Background: Recently, there have been many studies on the harmful effects of radiation and the regulations on radiation safety have been toughened both at the in nation and abroad. This study aims to identify the perceptions and actions taken as to radiation safety, and the degree of knowledge related to radiation held by the radiologists working in large hospitals. Materials and Methods: ...

ABSTRACT The efficacy of gamma irradiation is well versed as a method of decontamination for food and herbal resources. In the present study, Cichorium intybus L. roots were irradiated at multiple doses of 1, 2, 4, 6, 8 and 10 kGy by a cobalt-60 irradiator. The irradiated and non-irradiated control samples were evaluated for total phenolic contents, chlorogenic acid assay, 2,2-diphenyl-1-...

calculus is a new calculus that integrates in a uniform and simple settings rst-order rewriting,-calculus and non-deterministic computations. This paper describes the calculus from its syntax to its basic properties in the untyped case. We show how it embeds rst-order rewriting and-calculus. Finally we shows how-calculus can be used to give an operational semantics to the rewrite based language...
