Expression of genes for respiratory chain dehydrogenases was investigated in potato (Solanum tuberosum L. cv. Desiree) leaves. The recently characterized nda1 and ndb1 genes, homologues to genes encoding the non-proton pumping respiratory chain NADH-dehydrogenases of Escherichia coli and yeast, were compared to genes encoding catalytic subunits of the proton-pumping NADH dehydrogenase (complex I).

We describe the epidemiology of all distal radial fractures in young adults (men 20-59 years, women 20-49 years) in Lund (1992-95) and Malmo (1994-95), Sweden. During the study period, there were 341 patients with 346 fractures in the two cities, found through the Hospital Register of Diagnoses in Lund and the register of the Radiology Department in Malmo. More than half of the fractures were disl

Three previously unknown high-energy gamma-ray transitions between 4.2 and 5.4 MeV were identified in the T-z=-1/2 nucleus Fe-51 following the fusion-evaporation reaction S-32(Si-28, 2alpha1n)Fe-51. These transitions represent decays of core excited states. The gamma rays were detected in the Ge detector array Gammasphere combined with the neutron detector system Neutron Shell and the charged-part

Background: The bactericidal effect of some antibiotic and antineoplastic agents commonly used in clinical practice was investigated to analyse whether the combinations act synergistically, have indifferent or antagonistic antibacterial effects compared to the effect of the antibiotics alone. Methods: The rate of killing of meropenem, ceftazidime and tobramycin was studied against six different st

UV-B treatment of thylakoid membranes or fractions derived from them accelerates the first rise (Fo---Fi phase) of variable fluorescence and slows down the second (Fi---Fm) rise. This can be observed for all membrane fractions but to different extents. The grana fraction is affected more by the UV-B treatment than are the intact thylakoids and the stroma lamella fraction. An exogenous electron acc

A phase of approximate composition SbVO4 has been reported in the literature as a key component in new catalysts for the ammoxidation of propane to acrylonitrile. Sb0.92V0.92O4 was prepared by heating equimolar amounts of Sb2O3 and V2O5 in air at 1073 K for 2 hr. The chemical composition was determined by thermogravimetry and energy dispersive X-ray microanalysis. The crystal structure at 293 K wa

A combination of x-ray absorption and resonant photoemission (RPE) spectroscopy has been used to study the electronic structure of the one-dimensional conjugated polymer poly (para-phenylenevinylene) in nonordered (as prepared) thin films. The dispersion of RPE features for the decay to localized and delocalized bands are qualitatively different. A theory for band dispersion of RPE in polymers is

This study describes the integrated sympathetic/metabolic control of capillary pressure (Pc) and filtration in cat skeletal muscle as studied during graded exercise and superimposed graded (2, 6 and 16 Hz) vasoconstrictor nerve excitation. The applied technique permitted simultaneous analysis of the underlying changes of resistance in the whole vascular bed (RT) and in its large-bore arterial resi

Ground handling work performance is an important part of the civil aviation flight cycle. Well-functioning safety management for minimizing the risk for accidents is vital and dependent on the safety culture. This article reports on a safety culture assessment of a ground handling company using a multiplex approach method. The study is included in the establishment of reference data concerning saf

Egypt has one of the world's highest prevalences of hepatitis C virus (HCV) infection, with a majority of genotype 4 infections. To explore the genetic diversity of HCV in Egypt, sera from 131 Egyptians [56 from community studies, 37 chronic hepatitis patients, 28 hepatocellular carcinoma (HCC) patients and 10 patients with non-Hodgkin's lymphoma] were genotyped by restriction fragment-length poly

SAMMANFATTNING Rapporten är en översiktlig behandling av praktiska frågeställningar och problem i samband med putsade fasader. Olika fasadbehandlingar beskrivs med avseende på ingående material, egenskaper och användningsområden. I huvudsak behandlas oorganiska tjockputser, oorganiska och organiska ytskikt samt impregneringar. De vanligaste tekniska problemområdena i samband med putser och ytskikt

A case-control study compared 129 men with earlier partial gastrectomy (operation during the period 1952-1961) with 216 men from a community-based population study. All were born 1910-1915 and the mean age was 72 years. Men with a previous partial gastrectomy had vertebral fractures in 19% compared with 4% (P < 0.01) in the control population. Bone mineral density (BMD) in the right calcaneus meas
