The Run-6 included the machine operation at different beam energies and with different orientation of beam polarization at the collision points. The machine operation at lOOGeV and 31.2 GeV provided physics data of polarized proton collisions to the STAR, PHENIX and BRAHMS experiments. Record levels of the luminosity (up to 3.5.1031 cm-* s-' peak) and proton beam polarization (up to 65%) were achieved during the lOOGeV operation. The beam polarization was preserved during the acceleration by using Siberian Snakes, based on helical magnets. The polarization orientation at STAR and PHENIX experiments was controlled with helical spin rotators. During different stages of the run the physics data were provided with longitudinal, vertical and horizontal orientations of the beam polarization at the collision points. Total luminosity integrals of 45 pb-' at 100 GeV and 0.35 pb" at 3 1.2 GeV were delivered to the experiments.

Die als Beton-Bogenbruecke mit langen Zugangsrampen ausgefuehrte Fuss- und Radwegbruecke ist Teil eines Gruenraumprojektes zur Verbindung verschiedener Parks und Schulen. Wegen der oertlichen Baugrundverhaeltnisse und der in der Nachbarschaft noch zu errichtenden Hochhaeuser wird die Bruecke nach Herstellung verschiedene Setzungsphasen durchlaufen. Um darauf reagieren zu koennen, wurden statt der ueblichen Topflager Hublager eingebaut, die Setzungen bis zu 50 mm ausgleichen koennen. Mit diesen Lagern ist es moeglich, die gesamte Struktur unter voller Belastung anzuheben. An die Lager sind verschiedene Messsysteme angeschlossen, mit denen die vertikale Auflast staendig kontrolliert werden kann. Der Fahrbahntraeger der Bogenbruecke ist mit Haengern an den Boegen angeschlossen. Infolge der schlanken Konstruktion, den nicht exak...

Creatinine clearance was depressed significantly (P less than 0.005) and blood urea nitrogen (BUN) increased in CRF rats when compared with the sham-operated (S) controls. CRF caused no apparent change in body weight but significantly increased pancreatic weight as well as increased DNA, RNA, and protein content. Pancreatic protein-to-DNA and RNA-to-DNA ratios were also found to be significantly higher in CRF rats than in the S controls. Trypsin-like activity and immunoreactive cationic trypsinogen levels were both increased in the pancreas of CRF rats, but not in their serum. On the other hand, protease inhibitory activity in the pancreas and serum was significantly decreased by CRF. The ability of the dispersed pancreatic acini isolated from CRF rats to incorporate [3H]-leucine into protein, in the absence and presence of 0.25 nM cholecystokinin octapeptide (CCK-8), was found to be lower tha...

Digestive Enzymes and Protease Inhibitors in Plasma from Patients with Acute Pancreatitis

On admission, plasma levels of amylase and immunoreactive cationic trypsin(ogen) (IRCT) and elastase 2 (IRE 2) were found to be 50 +/- 10 ng/ml, 340 +/- 64 ng/ml, and 190 +/- 15 ng/ml, respectively, in all groups of patients. These enzymes levels remained high for the first 2 days following hospitalization and then decreased, although amylase and IRCT levels remained elevated above normal values throughout the study period (2 weeks). In general amylase and IRCT were lower in patients with concomitant ascites, pancreatic pseudocysts, or abscesses, and higher in patients who died, as compared to the pancreatitis group as a whole. In these patients, levels of immunoreactive alpha 1-protease inhibitor (alpha 1-PI) and alpha 2-macroglobulin (alpha 2-M) remained relatively constant at the lower end of the normal range throughout the study period. Inhibitor levels in plasma were unaffected by the etiology of pancreatitis or the occurrence of complications. A similar trend was seen with plasma levels of lysosomal hydrolases. The results indicate that in this group of patients, plasma levels of pancreatic digestive enzymes were reflective of the clinical features and severity of the disease, as well as the time following the acute attack that brought the patient to the hospital.

Over the last few years the process of IBS was carefully studied in RHIC with dedicated IBS measurements and their comparison with the theoretical models. A new lattice was recently designed and implemented in RHIC to suppress transverse IBS growth, which lowered the average arc dispersion by about 20% [1]. This lattice became operational during RHIC Run-8. We review the IBS suppression mechanism, IBS measurements before and after the lattice change, and comparisons with predictions.

The diagnosis is a challenge for clinicians and a delay in iagnosis can result in significant disability. Opinions differ mongst surgeons and anaesthetists as to the impact choice of ostoperative analgesia can have on the diagnosis of compartment yndrome of the limbs.

Biochemical studies in peritoneal fluid from patients with acute pancreatitis

In this group the concentrations of amylase (354 +/- 98 ng/ml), immunoreactive cationic trypsinogen (1840 +/- 238 ng/ml), and immunoreactive elastase 2 (1492 +/- 262 ng/ml) were greatly elevated in comparison to the corresponding serum values. Enzyme levels in ascites from the idiopathic pancreatitis group tended to be higher than the levels from the other two groups. Activity of acid phosphatase and beta-glucuronidase was significantly higher in ascites compared to serum in all groups. On the other hand, levels of immunoreactive alpha 1-protease inhibitor and alpha 2-macroglobulin in ascites fluid were about half the average concentrations reported for normal serum. Significant amounts of tryptic amidase activity (61.7 +/- 13.7 micrograms/ml) were observed, indicating a trypsin-alpha 2-macroglobulin complex. These data indicate an imbalance in the protease-to-inhibitor ratio in ascites fluid from patients with acute pancreatitis. Coupled with elevated ribonuclease activity (27.4 +/- 3.4 units), a positive methemalbumin test in 23 of 24 patients (1.1 +/- 0.4 mg hematin/100 ml), and an average protein concentration of 4.0 +/- 0.2 g/100 ml, these observations demonstrate that abdominal paracentesis and the biochemical analyses of ascites fluid provide useful information related to the biochemical events in acute pancreatitis and may be useful in the diagnosis of difficult cases, but their predictive value of severity remains to be established.

The present study, using specific radioimmunoassays for pancreatic elastase 2 (IRE2) and cationic trypsin(ogen) (IRCT), investigates the concentrations of these proteases which are known to circulate in blood, in abdominal aortic aneurysms. Aortic specimens were obtained from 32 patients with aneurysms and 21 patients with atherosclerotic occlusive disease. Aortic tissue, obtained at autopsy from young adults, served as controls. Elastase-like activity was 300% and 800% higher, respectively, in aortic homogenates from aneurysms in comparison to occlusive disease and control aortic tissue. This was associated with 1.4-fold higher level of IRE2 and 2.7-fold higher levels of IRCT as compared to occlusive disease. Although there was no significant difference in the aortic collagen concentration among all 3 groups, the elastin content of aneurysmal aorta was 85% and 74% lower, respectively, in comparison to control and occlusive aorta. The results of this investigation demonstrate the presence of pancreatic elastase 2 and cationic trypsin(ogen) in abdominal aortic aneurysmal tissue and suggest that circulating pancreatic proteases contribute to the pathophysiology of aneurysms of the infrarenal aorta.

This systematic review examines whether modern acute pain management techniques contribute to delayed diagnosis. A total of 28 case reports and case series were identified which referred to the influence of analgesic technique on the diagnosis of compartment syndrome, of which 23 discussed epidural analgesia. In 32 of 35 patients, classic signs and symptoms of compartment syndrome were present in the presence of epidural analgesia, including 18 patients with documented breakthrough pain. There were no randomized controlled trials or outcome-based comparative trials available to include in the review. Pain is often described as the cardinal symptom of compartment syndrome, but many authors consider it unreliable. Physical examination is also unreliable for diagnosis. There is no convincing evidence that patient-controlled analgesia opioids or regional analgesia delay the diagnosis of compartment syndrome provided patients are adequately monitored. Regardless of the type of analgesia used, a high index of clinical suspicion, ongoing assessment of patients, and compartment pressure measurement are essential for early diagnosis.
