Effectiveness of the ultrasonic coagulating shears, LigaSure vessel sealer, and surgical clip application in biliary surgery: a comparative analysis.

Advancements in laparoscopic surgery are often dictated by the limitations of technical instrumentation. Energy sources other than electrosurgery have become popular with the promise of quick and effective vascular control. With their success surgeons have begun using these on structures other than blood vessels with little or no data establishing their efficacy or safety.

Trends in and determinants of mortality in the elderly population of Matlab, Bangladesh.

The utility of hemodynamic measurements acquired by pulmonary artery catheterization.

Background: Concerns about the utility of pulmonary artery catheters (PAC) stimulated us to assess the impact of one of the parameters measured by the PAC, the pulmonary capillary wedge pressure (PCWP), on our clinical practice.

Methods: The PCWP was recorded at 4- to 6-hour intervals on 50 patients for the first 48 hours following aortic aneurysm repair. We then reviewed the patients' records looking for evidence that the PCWP measurements were used to guide therapy.

Capillary gas chromatography determination of aliphatic hydrocarbons in fish and water from Oman.

Aliphatic hydrocarbon residues were monitored in two fish species, Indian mackerel (Rastrelliger Kanaguria) and Indian scad (Decapterus russelli) collected from local markets in three different cities in Oman. Residues were also monitored in water samples collected from two sites of the Gulf of Oman. Sampling was conducted twice, in July and again in February to have a thorough understanding of the dynamics of aliphatic hydrocarbon residues.
