Growing correlation length on cooling below the onset of caging in a simulated glass-forming liquid.

We present a calculation of a fourth-order, time-dependent density correlation function that measures higher-order spatiotemporal correlations of the density of a liquid. From molecular dynamics simulations of a glass-forming Lennard-Jones liquid, we find that the characteristic length scale of this function has a maximum as a function of time which increases steadily beyond the characteristic length of the static pair correlation function g(r) in the temperature range approaching the mode coupling temperature from above. This length scale provides a measure of the spatially heterogeneous nature of the dynamics of the liquid in the alpha-relaxation regime.

[Reduced quality of life in liver cirrhosis]. / Redukcija stupnja kvaliteta zivota u cirozi jetre.

BACKGROUND: Greater interest for quality of life in chronic diseases has been given recently. Method for examination is application of SF-36 form. In this study we followed changes in quality of life for patients with liver cirrhosis in Bosnia and Herzegovina. PATIENTS AND METHODS: 45 patients suffered from liver cirrhosis, 15 in class A, 15 in class B and 15 in class C according to Child, completed answers in form SF-36. 45 healthy control volunteers completed the same form. Results of score were compared to control group and to each other. RESULTS: Significantly reduced quality of life in physical functioning and role physical were in class Child A compared to control group. In class Child B significant decrease in score for physical functioning, general health perception and energy and vitality compared to Child A. In Child C 6 of 8 scores were significantly decreased compared to class Child B. Ascites decreased significantly score for quality of life in Class Child B and in class Child C portal encephalopathy decreased quality of life too. CONCLUSION: Health related quality of life was reduced in liver cirrhosis. Quality of life was reduced more in disease with more complications.

[Effect of pantoprazole, amoxicillin and metronidazole treatment on the level of H. pylori eradication and the histological image of antral gastritis in patients with duodenal ulcer]. / Ucinak tretmana pantoprazolom, amoksicilinom i metronidazolom na stupanj eradikacije H. pylori i histolosku sliku antralnog gastritisa kod pacijenata sa duodenalnim ulkusom.

BACKGROUND: Relationships between Helicobacter pylori infection, inflammatory changes in antral region of gastric mucosa, and duodenal ulcer is well known and documented in a large number of studies. This trial is designed to examine effect of one week regimen of Pantoprazole, Amoxycillinum and Metronidazol to eradication of H. pylori, duodenal ulcer healing and histological changes on gastric mucosa. PATIENTS AND METHODS: 30 patients with active duodenal ulcer, H. pylori-positive, 16 male, with average age 47.12 +/- 13.13 yrs (AVG +/- STD) and 14 female patients with average age 44.47 +/- 12.29 yrs were included in trial. Biopsy of gastric antral region were performed in each patient. Patients were given Pantoprazole 40 mg bid, Amoxycillinum 1000 mg bid, Metronidazolum 500 mg bid for 7 days. After 7 days of treatment, control endoscopy was performed with repeated rapid ureasa test for H. pylori and antral biopsy and with verification of duodenal ulcer healing. Patients were followed up for 24.3 +/- 9.7 weeks for occasion of subjective symptoms. RESULTS: 96.67% patients were presented with eradicated H. pylori, complete ulcer healing was found in 83.34% patients after one week regimen (13.33% patients with ulcer reduced on one third of previous described), 73.33% of patients were presented with histologically feature of chronic gastritis turned from active to stationary phase. CONCLUSION: One week regiment with Pantoprazole, Amoxycilline and Metronidazole is effective, and beside a high rate ulcer healing and eradication of H. pylori it provides an improvement of histological feature of antral gastritis.

[Relation of laboratory parameters to complications of liver cirrhosis]. / Relacije laboratorijskih parametara u cirozi jetre sa komplikacijama.

Liver cirrhosis is characterized with alterations in hepatocytic perfusion, decreasing in number of hepatocytes and with seriously impared synthetic function of liver (hypoalbuminemy, inversion of albumino-globulinic ratio, hypoprothrombinemia). In a group of patients, suffered of liver cirrhosis with complication, we attempted to establish relationships between some of the typical clinical values: body weight in function of ascites evacuation, protein, albumin and value of prothrombin time in function of different groups of activity of aminotransferase in sera (AspAT, AlaAT) of improved and dead patients. We found a positive correlation for different groups of aminotransferase activities and laboratory values typical for liver cirrhosis with complications.
