BACKGROUND AND PURPOSE Reduction of cerebral blood flow results in several acute metabolic disturbances, including a reduction in Na,K-ATPase activity. The relation between this reduction and the onset of edema is unknown, as is the effect of restoration of blood flow. Therefore, we investigated the role of decreased Na,K-ATPase activity in the pathogenesis and time course of ischemic brain ede...

Predictors for operative mortality (OM) were studied in 172 consecutive patients (pts) undergoing coronary artery grafts (CAG) for angina pectoris.Seventy eight pts had Class IV angina; of the 147 patients given propranolol, 41 were gradually withdrawn from propranolol and finally discontinued 24 hours before surgery, and 106 were abruptly withdrawn from propranolol 24 hours before CAG; 20 pts ...

In this research a physical model is presented. A trapezoidal shape of channel with 1.45 m width, 1 meter depth and banks slope of 1H: 1.5V was used. Circular piers (6, 8 and 10cm diameter) were tested under three different flow discharges of 50, 65 and 80 lit/s and three different median bed material sizes equal to 0.94, 1.31 and 2.12 mm. Seven different longitude distance to pier diameter rat...

background: as we all know, sperm has the capacity to take up foreign dna, therefore, sperm mediated gen transfer can be an inexpensive and simple method in animal transgenesis in various species. however, there is not sufficient evidence of dna uptake by ovine spermatozoa. objectives: the purpose of the present study was to examine the uptake of human lysozyme gene contained plasmid (pegfp-ire...

OBJECTIVE To determine the durations of the local anesthetic effect and plasma procaine concentrations associated with 5- and 10-mg doses of procaine hydrochloride (with or without 100 microg of epinephrine) administered SC over the lateral palmar digital nerves of horses. ANIMALS 6 healthy adult horses. PROCEDURES The hoof withdrawal reflex latency (HWRL) period was determined by use of a ...

Background and study aims: Colonoscopy with portal inhaled methoxyflurane (Penthrox) is highly feasible with low sedation risk and allows earlier discharge. It is unclear if subjects can return to highly skilled psychomotor skill task shortly after Penthrox assisted colonoscopy. We evaluated the psychomotor and cognitive effects of 15-minute inhalation of Penthrox in adults. Patients and method...

BACKGROUND AND PURPOSE Cerebral ischemia has been shown to result in peripheral inflammatory responses followed by long-lasting immunosuppression. Our recent study demonstrated that intravenous delivery of regulatory T cells (Tregs) markedly protected against transient cerebral ischemia by suppressing neutrophil-derived matrix metallopeptidase 9 production in the periphery. However, the effect ...

BACKGROUND Hypocalcemia and nerve injury are the most severe complications after thyroid surgery. The duration of surgery has not been previously considered as a risk factor for postoperative complications in patients undergoing total thyroidectomy. We sort to investigate the influence of prolonged surgery on postoperative complications in patients undergoing total thyroidectomy. METHODS We h...

ETHODS A 12-lead ECG was continuously recorded during 24 ours in 20 patients with BS (ages 49 12) and 10 healthy ubjects (ages 32 7). Using two-dimensional binning we obained average QRS-T complexes every 30 minutes (time bins) and t different RR intervals (rate bins) for each subject. ST level was easured at five different points located 90, 100, 110, 120, and 40 ms after Q onset (Qo). In BS p...

Methods Elective adult cardiac surgical patients between 1997 and 2001 at the Medical University of Vienna were included. The cohort was split into two groups: Patients with an elevated SCr >1.3 mg.dL and ≤1.3 mg.dL. Within 120 minutes after end of surgery, the ΔCrea between the first measured SCr and the baseline SCr value was calculated for each patient. Mortality rates were calculated stepwi...
