comparative biodistributions and rates of catabolism of radiolabelled anti-cea monoclonal antibody and control immunoglobulin in nude mice with human tumour xenografts showing specific antibody localization.the rate of catabolism of a radiolabelled monoclonal anti-cea antibody has been compared with that of control igg1 in control nude mice and in mice with cea producing xenografts and antigen negative xenografts. the rate of catabolism of antibody, but not of igg, was increased 3-4 fold in mice with xenografts localizing the antibody, but not in mice with antigen negative tumours. there was no evidence of immune complex formation and/or clearance of antibody from the serum of xenografted mice and ...19873478194
central nervous system trauma.traumatic injury to the central nervous system causes immediate damage and sets in motion a complex series of pathophysiologic events that result in further neuronal injury. this secondary damage seems to be related to changes in blood flow and pressure on a systemic, regional, and microvascular level. currently, there is evidence that these changes are, in part, mediated by endogenous opioids and arachidonic acid metabolites, namely thromboxane a2. medical management is generally designed to in ...20123497697
simple tailored microcomputer system for the obstetrical ultrasound laboratory.as more sophisticated ultrasound instrumentation has become available, more complete and detailed examinations, including computer-manipulated data sheets, have been demanded by referring clinicians. in order to fill the clinical need, many suppliers have designed and promoted computer systems of unfortunately prohibitive costs. the purpose of this paper is to demonstrate the simplicity of designing a personally tailored data sheet and ease of programming one of the current commercially availabl ...20123511272
[characteristics of the organization of cell proliferation in plants in relation to the problem of stem cells].cellular patterns of continual cell proliferation are considered in plants and animals. in plants, the cells, analogous to the animal stem cells, can be formed many times during plant ontogenesis. their functioning as stem cells is determined by their position in the growing organ. this is the reason why a plant can grow for a very long time. there are some common features of cellular patterns of proliferation in plants and animals providing the stability and optimal subordination between cell p ...20123521007
