| use of the glucose oxidase/peroxidase method for glucose assay leads to overestimation of the inhibition of gluconeogenesis by aminopyrine. | 4-aminoantipyrine strongly inhibits glucose determination by the glucose oxidase/peroxidase/dianisidine assay but does not interfere in the assay using glucose-6-phosphate dehydrogenase, hexokinase and atp. as a result, the inhibition of gluconeogenesis by aminopyrine reported to be 50-90% (bánhegyi, g., mandl, j., antoni, f. and garzó, t. (1987) biochim. biophys. acta 927, 406-416) is strongly overestimated and amounts to only 10-30%. | 1989 | 2713417 |
| protein kinase c is activated in glomeruli from streptozotocin diabetic rats. possible mediation by glucose. | glomerular inositol content and the turnover of polyphosphoinositides was reduced by 58% in 1-2 wk streptozotocin diabetic rats. addition of inositol to the incubation medium increased polyphosphoinositide turnover in glomeruli from diabetic rats to control values. despite the reduction in inositol content and polyphosphoinositide turnover, protein kinase c was activated in glomeruli from diabetic rats, as assessed by an increase in the percentage of enzyme activity associated with the particula ... | 1989 | 2708528 |
| design, expression, and crystallization of recombinant lectin from the garden pea (pisum sativum). | the propeptide form of the lectin from the garden pea (pisum sativum agglutinin) has been expressed in escherichia coli by attaching its cdna to an inducible promoter. by a number of criteria, including the ability to form dimers, hemagglutination titer, western blot, and enzyme-linked immunosorbent assay, the resulting propeptide molecule is virtually indistinguishable from the mature proteolytically processed lectin isolated from peas. preliminary crystallization experiments using the recombin ... | 1989 | 2708344 |

| [b-cell chronic lymphocytic leukemia complicated by autoimmune thrombocytopenic purpura]. | a 74-year-old japanese male was admitted because of anemia. hepatosplenomegaly, lymphoadenopathy, and purpura were not found. the laboratory data on admission revealed that the white-cell count was 9,400/microliters, the hemoglobin 11.1 g/dl, and the platelet count 17,000/microliters. platelet-associated igg was 794.2 ng/10(7) cells. the patient was diagnosed as having autoimmune thrombocytopenic purpura (atp) at this time. he was treated with prednisolone, but his thrombocytopenia not improve. ... | 2006 | 1635169 |
| evidence for natural transfer of a tetracycline resistance gene between bacteria from the human colon and bacteria from the bovine rumen. | previously, we demonstrated conjugal transfer of a specially constructed shuttle vector, prdb5, from the human colonic anaerobe bacteroides uniformis to the ruminal anaerobe prevotella (bacteroides) ruminicola b(1)4. we have now shown that naturally occurring gene transfer elements in bacteroides species and prevotella ruminicola can also be transferred between these two genera. a self-transmissible chromosomal element originally found in a clinical isolate of bacteroides fragilis (tcr emr 12256 ... | 1992 | 1599250 |
| external cephalic version and daily post-versional maternal self-assessment of fetal presentation. a prospective study. | external cephalic version (ecv) using tocolysis is a widely recognized low-risk intervention in cases of breech presentation, particularly in areas where resources are scarce and the perinatal mortality is high in vaginal breech deliveries. in such a setting, pregnant women were trained to make regular self-assessments of the presenting fetal part after ecv in order to detect spontaneous reversions to breech presentation. it was found that such maternal involvement could significantly improve th ... | 2006 | 1563651 |

| antibiotic sensitivity of the bacteroides fragilis group in europe. european study group. | rates of resistance to 12 antibiotics were determined for 1,289 isolates of bacteroides fragilis group submitted in 1988-1989 by 22 laboratories in 15 european countries. there was no resistance to metronidazole (breakpoint 8 mg/l) and only one isolate was resistant to chloramphenicol (breakpoint 8 mg/l). resistance was uncommon for imipenem (0.3% at greater than 4 mg/l), amoxicillin/clavulanate (1% at greater than 8 mg/l), cefoxitin (3% at greater than 32 mg/l), mezlocillin (6% at greater than ... | 1992 | 1396748 |
| recovery of bacteroides fragilis group from clinical specimens following antimicrobial therapy. | over a period of 14 years (1973-1987), 3165 specimens submitted to the microbiology laboratory demonstrated the recovery of anaerobic bacteria. a total of 988 bacteroides fragilis group isolates were recovered (0.3 isolates per specimen). bacteroides fragilis accounted for 62% of the total of all b. fragilis group isolates, bacteroides thetaiotaomicron for 15%, bacteroides vulgatus for 8%, bacteroides ovatus for 7%, bacteroides distasonis for 6%, and bacteroides uniformis for 2%. of the 988 b. f ... | 1992 | 1393825 |
| antigen-receptor complex stimulation triggers protein kinase c-dependent cd11a/cd18-cytoskeleton association in t lymphocytes. | although it is well accepted that intercellular adhesion involving the cd11a/cd18 (lfa-1) complex is critical in a wide array of t cell-dependent processes, recent demonstrations of an lfa-1 high avidity state, induced by triggering the t cell receptor (tcr) complex, has raised questions about the intracellular signals generated and molecular events leading to effective cell coupling, as well as their orderly sequence. in this study, we assessed the effects of t cell activation on the actin-base ... | 2006 | 1346786 |
| effect of beta-lactamase inhibitors on beta-lactamases from anaerobic bacteria. | three beta-lactamase inhibitors in clinical use--clavulanic acid, sulbactam and tazobactam--were investigated for their activity on beta-lactamases from bacteroides uniformis, clostridium butyricum and fusobacterium nucleatum. purification of the beta-lactamases was carried out by anion-exchange chromatography, gel filtration and fplc. the inactivation of beta-lactamase activity was determined spectrophotometrically with nitrocefin as substrate. various concentrations of the inhibitors were prei ... | 1992 | 1338315 |
| effect of clavulanic acid, sulbactam and tazobactam on three different beta-lactamases from bacteroides uniformis, clostridium butyricum and fusobacterium nucleatum. | the effect of three beta-lactamase inhibitors, clavulanic acid, sulbactam and tazobactam used in clinical practice were compared for their activity against purified beta-lactamases from bacteroides uniformis, clostridium butyricum and fusobacterium nucleatum. the enzymes from b. uniformis and c. butyricum were produced in fermenters under controlled growth conditions and the enzyme from f. nucleatum was produced in batch cultures. purification of the beta-lactamases was achieved by anion-exchang ... | 1992 | 1331018 |
