A Method for Microencapsulation of Cells and a Device for Its Realization.

The device for cell encapsulation makes it possible to fabricate microcapsules of a preset size with even smooth surface, without defects or adhesion to each other, with viable cells inside the capsule. The cells were derived from newborn piglet pancreases.

Level of Blood Cell-Free Circulating Mitochondrial DNA as a Novel Biomarker of Acute Myocardial Ischemia.

Changes in the level of blood cell-free circulating mitochondrial DNA were examined during experimental adrenaline-induced myocardial injury in rats. The amount of mitochondrial DNA in the blood was significantly elevated at 48 and 72 h after subcutaneous injection of adrenaline solution, and it was accompanied by development of multiple small-focal myocardial ischemia. This suggests that the measured level of blood cell-free circulating mitochondrial DNA might be used as a biomarker of acute myocardial ischemia.

Comparison of fondaparinux with low molecular weight heparin for venous thromboembolism prevention in patients requiring rigid or semi-rigid immobilization for isolated non-surgical below-knee injury.

BACKGROUND: In several small studies, anticoagulant therapy reduced the incidence of venous thromboembolism (VTE) in patients with isolated lower-limb injuries. OBJECTIVES: To compare the efficacy and safety of fondaparinux 2.5 mg (1.5 mg in patients with a creatinine clearance between 30 and 50 mL min(-1) ) over nadroparin 2850 anti-factor Xa IU. PATIENTS AND METHODS: In this international, multicenter, randomized, open-label study, patients with an isolated non-surgical unilateral below-knee injury having at least one additional major risk factor for VTE and requiring, in the Investigator's opinion, rigid or semi-rigid immobilization for 21-45 days with thromboprophylaxis up to complete mobilization received subcutaneously once-daily either fondaparinux or nadroparin. The primary efficacy outcome was the composite of VTE (symptomatic or ultrasonographically detected asymptomatic deep vein thrombosis of the lower limb or symptomatic pulmonary embolism) and death up to complete mobilization. The main safety outcome was major bleeding. RESULTS: We randomized 1349 patients (mean age 46 years): 88.7% had a bone fracture, and 83.8% had a plaster cast fitted (mean duration of immobilization, 34 days). The primary efficacy outcome occurred in 15 of 584 patients (2.6%) in the fondaparinux group and 48 of 586 patients (8.2%) in the nadroparin group (odds ratio, 0.30; 95% confidence interval [CI], 0.15-0.54; P < 0.001). A single major bleed was experienced by fondaparinux-treated patients and none by nadroparin-treated patients. These results were maintained up to the end of follow-up. CONCLUSIONS: Fondaparinux 2.5 mg day(-1) may be a valuable therapeutic option over nadroparin 2850 anti-FXa IU day(-1) for preventing VTE after below-knee injury requiring prolonged immobilization in patients with additional risk factors.

[Pathophysiological mechanisms of bacterial endotoxicosis in disseminated peritonitis].

Using methods of nuclear medicine in experiment, we studied pathophysiologic mechanisms of bacteriemia in disseminated peritonitis in various laboratory animals. The results give grounds to consider regularities revealed to be universal.

[Staged correction of surgical pathology of the stomach ("Damage Control") in conditions of decompensated hypovolemic shock]. / Etapnaia korrektsiia khirurgicheskoi patologii zhivota ("Damage Control") v usloviiakh dekompensirovannogo gipovolemicheskogo shoka.

Based on an analysis of results of treatment of 184 patients the authors make a conclusion that staged surgical correction is an expedient method for traumas of the abdomen and acute intestinal obstruction with necrosis of the bowel.
