an elisa for anti-thymocyte autoantibody in nzb mice. comparison with the cytotoxic assay.an elisa is described for the detection of anti-thymocyte antibody found in the serum of nzb autoimmune mice. this assay avoids the disadvantages of previous assay techniques which require carefully selected complement sources and/or radioactive labelled target cells. thymocytes from a variety of strains of mice can be used as the antigenic targets, and the plates stored as long as 1 month. the lymphoma line el4 can be used as the antigenic target in this assay, but it not as sensitive to most s ...20123497206
hemorrhagic complications of long-term anticoagulant therapy for ischemic cerebral vascular disease.the main complication of anticoagulant therapy is bleeding. although the use of long-term oral anticoagulants in patients with transient cerebral ischemia and/or minor stroke is controversial, anticoagulants are still used in some instances. we have carried out a literature review of the risk of hemorrhage during long-term oral anticoagulant therapy in patients with cerebrovascular disease to determine the rate of bleeding and the clinical and laboratory risk factors which predispose patients to ...20123511568
neonatal status in relation to incision intervals, obstetric factors, and anesthesia at cesarean delivery.uterine incision to delivery interval has been suggested as a critical determinant of neonatal outcome; however, studies of skin incision and uterine incision to delivery intervals have usually not analyzed the contribution of obstetric factors relative to time factors in determining outcome. a group of 204 patients undergoing cesarean delivery were studied. stepwise multivariate regression was used to examine the relative contribution of obstetric and anesthetic factors to apgar scores and umbi ...20123651185
measured wall shear stress distribution pattern upstream and downstream of a unilateral stenosis by an electrochemical method.an electrochemical surface shear stress measurement was applied to a model of unilateral arterial stenosis. the unilateral stenosis model was made up of a removable stenosis plug, in an electrochemical shear stress measurement test section with 100 cathodes. three dimensional wall shear stress distribution was measured under steady flow field. at a relatively low reynolds number, re = 270, there was a characteristic high and low wall shear distribution pattern downstream of the unilateral stenos ...20123502769

an activation-collision mechanism for cholesterol transfer between membranes.we report the results of experiments which show that cholesterol transfer between membranes cannot proceed by aqueous diffusion, as widely held, but must involve a more complex mechanism. (a) the rate of transfer of [3h]cholesterol from red blood cells was found to vary inversely with the size of the acceptor particle (ghosts, vesicles of ghosts, liposomes, and plasma lipoproteins). (b) the transfer of [3h]cholesterol from red blood cells to ghosts was accelerated by the presence of plasma, even ...20123417649

origin of eukaryotic introns: a hypothesis, based on codon distribution statistics in genes, and its implications.a hypothesis for the origin of introns in eukaryotic genes is developed. by computer simulation it was found that the reading-frame lengths in a random nucleotide sequence are distributed in a negative exponential manner and that there exists an upper limit of about 200 codons in the length of the reading frames (rfs). these characteristics suggest that, if primordial dna contained a random nucleotide sequence, the most primitive cells would have been under selective pressure to eliminate interf ...20123457379
inhibition of clonogenic growth of fresh leukemia cells by unstimulated and il-2 stimulated nk cells of normal donors.we have demonstrated that unstimulated highly-enriched nk cells have the capability to inhibit the growth of fresh clonogenic leukemic cells from aml, cml and preleukemic patients. the nk-cell population mediating antileukemic reactivity exhibited lgl morphology and nkh1 and cd16 phenotype. the inhibition of leukemic growth could be mediated by cell-to-cell contact or by soluble factor produced by nk cells. antileukemia activity was only detectable when enriched population of lgl was utilized; n ...20123501042
a barbital derivative as an atypical antidepressant drug in mice.an isopropyl derivative of barbital (5,5-diethyl-2-(isopropyloxy)pyrimidine-4,6-dione, o2ib) was administered intraperitoneally 30 min before tests in mice. former experimental investigations have shown that o2ib has an antidepressant psychopharmacological spectrum. it increases toxicity of yohimbine in mice at 175 mg/kg, antagonises from 50 mg/kg on hypothermia induced by a high dose of apomorphine and is active on the behavioural despair test at 125 mg/kg. these effects are those observed with ...20123619970
