Double-Wire versus Single-Wire Sternal Closure in Obese Patients: a Randomized Prospective Study.

 Sternal instability after coronary artery bypass grafting (CABG) is a serious complication. Obese patients are at high risk for sternal instability after CABG. This study was conducted to assess the positive impact of double-wire sternal closure on sternal instability.

Filamentous brown algae infected by the marine, holocarpic oomycete Eurychasma dicksonii: first results on the organization and the role of cytoskeleton in both host and parasite.

The important role of the cytoskeletal scaffold is increasingly recognized in host-pathogen interactions. The cytoskeleton potentially functions as a weapon for both the plants defending themselves against fungal or oomycete parasites, and for the pathogens trying to overcome the resisting barrier of the plants. This concept, however, had not been investigated in marine algae so far.

The challenge of ST-segment elevation myocardial infarction.

Background/introduction: Acute coronary syndromes (ACS) represent a spectrum of ischaemic myocardial events that share a similar pathophysiology. ST-segment elevation myocardial infarction (STEMI), the most severe form of ACS short of sudden cardiac death, is a significant public health problem with an estimated 500,000 STEMI events every year in the United States.

Treatment/therapy: The mortality and morbidity associated with STEMI is significant.

Fibrinolytic activity and bleeding after cardiac surgery with cardiopulmonary bypass and low-dose aprotinin therapy.

Low-dose aprotinin inhibits hyperfibrinolysis in cardiac surgery. However, excessive postoperative bleeding and increased fibrinolysis may occur despite low dose-aprotinin administration. We investigated (i) whether fibrinolytic activity significantly rises under low-dose aprotinin administration, and (ii) whether this is associated with excessive postoperative bleeding (> or = 1000 ml/24 h).
