The first descriptions of an insoluble nuclear structure appeared more than 70 years ago, but it is only in recent years that a sophisticated picture of its significance has begun to emerge. Here we introduce multiple methods for the study of the nuclear matrix.

Terms such as isotopes and nuclear techniques often call to mind basic research of little or only minor practical importance for animal productivity and health. This is, however, not true. No other scientific tools have in our lifetime been of a significance equalling that of the isotopes in widening our insight into animal physiology and nutritional requirements. Last but not least, they have ...

systemic sclerosis is a generalized disorder of connective tissue clinically characterized by thickening and fibrosis of the skin and by distinctive forms of involvement of internal organs. one of the hallmarks of systemic sclerosis is the presence of serum autoantibodies against a variety of nuclear and cytoplasmic antigens. the primary purpose of this study was to identify the autoantibodies ...

Background: Several landmine detection methods, based on nuclear techniques, have been suggested during the recent years. Neutron energy moderation, neutron-induced gamma emission, neutron and gamma attenuation, and fast neutron backscattering are nuclear-based methods used for landmine detection. The aim of this study is to use backscattered neutron for landmine detection. Materials ...

basic physical principles of nuclear magnetic resonance imaging (n.m.r.i), a nonionizing medical imaging technique, are described. principles of nmri with other conventional imaging methods, ie, isotope scanning, ultrasonography and radiography have been compared. t1 and t2 and spin density (s.d.) factors and different image construction techniques based on their different combinations is discu...
