Presented software toolbox connects the PC MS Windows 3.1 based MATLAB 4 with a network of AD66 high performance boards. Each board includes one DEC AXP 64 bit RISC processor working on 233 Mhz with additional circuits supporting T4/T8 transputer links, C40 links or T9000 link standards. The Alpha-Bridge starts and controls parallel applications from within MATLAB or SIMULINK. Users can program...
Using PIRLS 2001 and PISA 2003 data for Germany, this paper examines whether secondgeneration immigrants and girls are graded worse in math than comparable natives and boys, respectively. Once all grading-relevant characteristics, namely math skills and oral participation, are accounted for, pupils should obtain same school grades. Results of a matching approach and class fixed effects regressi...
OBJECTIVES Metabolic dysfunction is a common hallmark of the aging process and aging-related pathogenesis. Blood metabolites have been used as biomarkers for many diseases, including cancers, complex chronic diseases, and neurodegenerative diseases. METHODS In order to identify aging-related biomarkers from blood metabolites, we investigated the specific metabolite profiles of mouse sera from...
Due to a combination of their promising anticancer properties, limited supply from the marine sponge source and their unprecedented molecular architecture, spirastrellolides represent attractive and challenging synthetic targets. A modular strategy for the synthesis of spirastrellolide A methyl ester, which allowed for the initial stereochemical uncertainties in the assigned structure was adopt...
Metabolomic discovery of biomarkers of type 2 diabetes (T2D) risk may reveal etiological pathways and help to identify individuals at risk for disease. We prospectively investigated the association between serum metabolites measured by targeted metabolomics and risk of T2D in the European Prospective Investigation into Cancer and Nutrition (EPIC)-Potsdam (27,548 adults) among all incident cases...
The use of stable isotopes in studies of carotenoid biosynthesis is reviewed, beginning with early work with l8 which defined the origin of oxygen in a range of xanthophylls. A series of experiments from our own laboratory is then described, in which 2H and 13C have been used to investigate the stereochemistry of cyclization to form C40 and C50 and i-ring carotenoids. Novel procedures involving...
Fullerenes have attracted considerable attention due to their unique chemical structure and potential applications which has opened wide venues for possible human exposure to various fullerene types. Therefore, in depth knowledge of how fullerene may interfere with various cellular processes becomes quite imperative. The present study was designed to investigate how the presence of fullerene af...
Na+/H+ exchangers in the brush-border (luminal, apical) membrane of renal proximal tubules are responsible for active, transcellular reabsorption of NaHCO3 and NaCl. Although well characterized kinetically, the protein that mediates Na+/H+ exchange in the renal brush border has not been identified. Several Na+/H+ exchanger genes, including NHE1, NHE2, NHE3, and NHE4, are expressed in the kidney...
Immortalized p19(ARF) null hepatocytes (MIM) feature a high degree of functional differentiation and are susceptible to transforming growth factor (TGF)-beta driven growth arrest and apoptosis. In contrast, polarized MIM hepatocytes expressing hyperactive Ha-Ras continue proliferation in cooperation with TGF-beta, and adopt an invasive phenotype by executing an epithelial to mesenchymal transit...
