Two prospective studies of the occurrence and clinical significance of post-transfusion hepatitis non-A, non-B were performed in Malmo, Sweden. In both studies, patients of a broad clinical spectrum were followed up 6 and 12 weeks after transfusion. In a 7 week study from 1983, hepatitis non-A, non-B occurred in 9/173 transfused patients (5.2%) versus 1/203 untransfused controls (0.5%) (p less tha

Despite its unparalleled merits for prostate cancer detection and staging, prostate-specific antigen (PSA) is not a marker for prostate cancer only, but also is expressed in benign conditions. For early detection, limitations of PSA are obvious. Its widespread use has led to an extensive amount of expensive and often unnecessary diagnostic procedures associated with significant morbidity. Total PS

The normal pinch strength was determined with the Mannerfelt-Ulrich intrinsic meter in 90 men and women aged 21-65 years. The pinch strength decreased with increasing age. The ratio dominant/nondominant hand was 1.12, 0.13 (mean, SD) for both men and women. The ratio would be useful in evaluating pinch strength under pathologic conditions.

Basement membranes are sheet like extracellular matrices that underlie or surround many cell types. They are crucial for key cellular events such as cell migration, proliferation, survival and differentiation. Vital components of all basement membranes are laminins, heterotrimeric combinations of different laminin chain isoforms. The different laminins and their subunits largely have a development

Density functional theory was employed to investigate the adsorption site and hyperfine interactions of nitric oxide adsorbed in Na-LTA (previous name NaA) zeolite. Three different cluster models of increasing complexity were used to represent the zeolite network: (1) a six-membered ring terminated by hydrogen atoms with one sodium ion above the ring, (2) as model 1 with the addition of three sodi

Popular Abstract in Swedish Avhandlingen behandlar olika aspekter av produktivitet och ekonomisk tillväxt i Afrika och består av fyra kapitel. I det första kapitlet utförs en analys av de faktorer som påverkar Afrikas tillväxt på lång sikt. Analysen är baserad på en studie av ett antal Afrikanska länder som genomgått stark ekonomisk tillväxt under längre perioder. Studiens främsta slutsatser är atThe thesis comprises an introductory chapter and four research papers. The introductory chapter provides a brief overview of recent economic growth performance in Africa, places the individual papers into a coherent context, summarizes the main findings, and discusses their relevance for economic policy. The first paper, The Role of Capital Accumulation, Adjustment and Structural Change for Take-

An association between the intake of heterocyclic amines (HAs) and the development of cancer has been observed in some epidemiological studies, while in other studies no such correlation has been found. HAs are mutagenic/carcinogenic compounds formed at low levels via the Maillard reaction and a free radical mechanism during cooking of animal tissue. The addition of pure antioxidants or foods cont
