Eighty-three Walldius arthroplasties, performed by one surgeon as salvage operation on the knee joint between 1966 and 1972, were independently reviewed. The fifty-seven living patients with sixty-seven arthroplasties were interviewed and examined and the clinical records of the deceased patients were inspected. Sixty-seven arthroplasties (81 per cent) were successful and sixteen failed (19 per...

The paper presents a study of various environmental factors which influence respira tion, glycolysis, and the Crabtree Effect in the Ehrlich ascites carcinoma cells. The factors examined for influence on respiration include: (1) pH in the presence and ab sence of glucose and (2) varying concentrations of inorganic phosphate in: (a) media used to wash the cells, (6) incubation media, with no sup...

Animal health surveillance in Great Britain (GB) is conducted through public and private initiatives, yet there is no consolidated information on these activities and their outcomes. We developed an inventory of livestock health surveillance programmes in GB to identify gaps in resource use and potential synergies that could be exploited. The inventory contained details of 36 livestock surveill...

1. When normal, monodisperse hemocyanin (60.5S) from Limulus Rolyphemus was irradiated in neutral buffer with x-rays, several new, more rapidly sedimenting ultracentrifugal components (86S, 107S, 122S) were produced, with a corresponding loss in the amount of the unaffected protein. The amount of the effect was roughly proportional to the amount of irradiation. 2. The new resolvable components ...

1. A method for the preparation of 8 to 10 liter quantities of T(2) virus lysates, titering 2 to 5 x 10(11) infectious units per ml. has been described. 2. Procedures have been developed for the concentration and purification of virus to a high specific infectivity. No fractionation procedure of the several used succeeded in further raising the specific infectivity of these purified preparation...

P.M., a seventy year old Polish-born male clerk, was referred to the Hematology Clinic in September 1963. Examination in another medical service in 1961 had revealed moderate hepatosplenomegaly, a platelet count of 900,000 per cu.mm. with normal red and white blood cell counts, and megakaryocytic hyperplasia in bone marrow with excessive platelet production and hyperplasia of the white cell ser...

We estimated the diagnostic skill of clinicians managing melanocytic skin naevi by measuring the percentage of malignant melanomas, premalignant and potentially malignant naevi, in 1896 excised melanocytic lesions submitted to a pathology service over 11 weeks. They comprised 8 per cent. The percentage increased with age: 4 per cent in the under-40s, 17 per cent in those aged 40-59, and 30 per ...

BACKGROUND & OBJECTIVES Insect growth regulators (IGRs) offer alternatives to conventional chemical larvicides that pose problem of resistance and environmental safety. However, only a limited number of IGRs have been approved for use in mosquito control. In the present study, two new formulations of the IGR diflubenzuron, 2 per cent granular (GR) and 2 per cent tablet (DT) were tested for its ...

BACKGROUND Discussion is ongoing regarding whether associating liver partition with portal vein ligation for staged hepatectomy (ALPPS) or portal vein occlusion is better in staged hepatectomy. The aim of this study was to compare available strategies using a two-stage approach in extended hepatectomy. METHODS A literature search was performed in MEDLINE, Scopus, the Cochrane Library and Emba...
