Using 68Ge : 14C dual-labeling, we investigated the absorption efficiency of diatom carbon for the cold water appendicularian Oikopleura vanhoeffeni. The absorption efficiency of bulk carbon (mean 5 67%) was not influenced by body size or ingestion rate. For the first time for a pelagic tunicate, food and feces were fractionated into their major biochemical constituents (i.e., low-molecular-wei...

The incidence of recruit injuries during basic training in the Irish Army is, to date undocumented. In this retrospective cohort study, the medical records of 415 recruits are examined. The lower limb predominated as the anatomical site of the majority of injuries. The overall incidence of male 'first time' injuries was 56.96 per 1000 man-week training. The corresponding female figure was 99.26...

sir,?uenius is the grip upon first principles. Surprise, therefore, is not awakened, when the modern methods of treating war wounds throw a fresh light upon the genius of the greatest of surgeons and a man with every element of genius, Lord Lister. Lister won his first success with his antiseptic system in 1868 and in 1870 the Franco-German war broke out. Preceding this war there had been the C...

D-Amino acid aminotransferase, purified to homogeneity and crystallized from Bacillus sphaericus, has a molecular weight of about 60,000 and consists of two subunits identical in molecular weight (30,000). The enzyme exhibits absorption maxima at 280, 330, and 415 nm, which are independent of the pH (5.5 to 10.0), and contains 2 mol of pyridoxal 5'-phosphate per mol of enzyme. One of the pyrido...

Reduction of specific energy consumption by 1 – 2% per year is typically what is considered feasible for end-use energy applications. This article tries to answer the question whether much higher rates, for example 5% and more are feasible for new equipment, installations and buildings. After examining some end-use functions in industry, buildings and the transport sector, it is concluded that ...

This article is also accessible online at: http://BioMedNet.com/karger Dear Sir, For the past 15 years, the appropriate treatment of end stage renal failure has included both continuous ambulatory peritoneal dialysis (CAPD) and haemodialysis. In some circumstances CAPD has been indicated as a more adequate option. However, the main handicap for CAPD patients is peritoneal infection [1], ranking...
