STUDY OBJECTIVE |
s: To examine the effects of low arterial BP (ABP) during reperfusion on the extent of myocardial infarction and on coronary blood flow (CBF) in an occlusion/reperfusion experimental model. |
DESIGN |
Prospective, randomized animal study. |
SETTING |
University hospital. |
PARTICIPANTS |
Normal pigs that were anesthetized, intubated, and mechanically ventilated. |
INTERVENTIONS |
Twenty-seven open-chest pigs underwent occlusion of the mid left anterior descending (LAD) coronary artery for 1 h followed by reperfusion for 2 h. During reperfusion, the animals were randomly assigned to either continuous infusion of nitroglycerin in therapeutic doses and fluid infusion at rates to maintain a mean AB... |
MEASUREMENTS AND RESULTS |
The hemodynamics and the coronary ABP distal to the occlusion were recorded throughout the experiment. In addition, the LAD CBF and peak hyperemia CBF before occlusion and during reperfusion periods were measured by transit-time flowmetry. At the end of the experiment, the infarcted left ventricular myocardial size was... |
CONCLUSIONS |
Low ABP during reperfusion increases the size of myocardial infarction and decreases CBF.Retrovirus-neutralizing antibodies in AML and AMMoL patients: stage-specific distribution. |
Plasma samples of patients with AML or AMMoL were tested for antibodies reacting with gp70 antigens of BaEV and GaLV as well as for antibodies neutralizing BaEV or GaLV. Both frequency and titer values of antibodies were higher in remission than in blastosis. Neutralizing activity could be detected only in those plasma... |

BACKGROUND & AIMS |
Heregulins (HRGs) regulate the proliferation and differentiation of various cell types. However, very little is known about their function in the gastrointestinal tract. The aim of this study was to investigate the role of HRGs on gastrointestinal cells. |
METHODS |
We examined the expression of erbB receptors and HRG-alpha in human gastric cancer cell lines, rat gastrointestinal epithelial cells, and human gastric fibroblasts by Western blot analysis or reverse-transcription polymerase chain reaction. Receptor phosphorylation and heterodimerization induced by HRG-alpha were detec... |
RESULTS |
Cancer cell lines and rat epithelial cells expressed erbB2 and erbB3, but protein expression of erbB4 was not detected. HRG-alpha was detected only in gastric fibroblasts. HRG-alpha activated tyrosine phosphorylation of epidermal growth factor receptor (EGFR), erbB2, and erbB3 and induced not only erbB3/erbB2 but also ... |
CONCLUSIONS |
The data suggest that HRG-alpha may affect epithelial cell proliferation through mesenchymal-epithelial interaction in the gastric mucosa.Role of base G-2 of pre-tRNAfMet in cleavage site selection by Escherichia coli RNase P in vitro. |
In this study, a protocol for the purification of fully active Escherichia coli RNase P holoenzyme from a strain overproducing both the C5 protein and the M1 RNA components is described. A total of 0. 8 mg of homogeneous enzyme, with a 1:1 protein/RNA subunit stoichiometry, was recovered from a 1 L bacterial culture. I... |
Background: DBA/2FG-pcy (pcy) mice harbor a homozygous Nphp3 missense mutation and develop nephronophthisis with renal interstitial fibrosis.
