High specificity in aminoacylation of transfer RNAs (tRNAs) with the help of their cognate aminoacyl-tRNA synthetases (aaRSs) is a guarantee for accurate genetic translation. Structural and mechanistic peculiarities between the different tRNA/aaRS couples, suggest that aminoacylation systems are unrelated. However, occurrence of tRNA mischarging by non-cognate aaRSs reflects the relationship be...
In order to select the mischarging mutants of Su+2 glutamine tRNA, auxotrophic amber mutants of E. coli K12 which cannot be suppressed particularly by Su+2 were screened. By utilizing these mutants, cysam235 and metam3, several tens of mischarging mutants of Su+2 were isolated, as those conferring altered suppression patterns for a set of tester amber mutants of bacteria and phages. Nucleotide ...
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...
Materials and methods We have evaluated 69 consecutive patients (39 male and 30 female) operated for rectal cancer in our ward. The preoperative investigation includes, according to guidelines for CRC treatment: pancolonscopy, chest radiography and a CT scan of the abdomen. The most appropriate surgical treatment was chosen depending on the results of the preoperative study (Table 1). A standar...
High-resolution 19F nuclear magnetic resonance spectroscopy at 7 T was used to study the effect of modulators on the metabolism of 5-fluorouracil (5-FUra, 115 mg/kg i.p.) in C38 murine colon tumors grown in C57BL/6 mice. Distinct 5-FUra metabolite patterns were found in perchloric acid extracts of these tumors after treatment. The 19F nuclear magnetic resonance spectra exhibited resonances repr...
Jojoba liquid wax is a mixture of esters of long-chain fatty acids and fatty alcohols mainly C38:2-C46:2. The oil exhibits excellent emolliency on the skin and, therefore, is a component in many personal care cosmetic formulations. The virgin oil is a component of the seed of the jojoba (Simmondsia chinensis) plant which occurs naturally in the Sonora Desert in the United States and northwester...
The physiological responses of alkenone unsaturation indices to changes in growth status of E. huxleyi and G. oceanica strains isolated from a water sample of the NW Paci®c were examined using an isothermal batch culture system. In both E. huxleyi and G. oceanica the unsaturation index U37 K0 changed during the growth period, but the eects of this change were dierent. This suggests that genot...
Milk fat is an important food component, and plays a significant role in the economics, functional nutrition, and chemical properties of dairy products. Dairy products also contain nutritional resources and essential fatty acids (FAs). Because of the increasing demand for dairy products, milk fat is a common target in economic fraud. Specifically, milk fat is often replaced with cheaper or read...
This study identifies affecting determinants in the marketing of Iranian crude oil. The research methodology is qualitative and quantitative simultaneously. The statistical sample includes experts, senior and executive managers, marketing directors, and the Information Systems Department of the National Iranian Oil Company. Data is collected through qualitative interviews and quantitative quest...
published in Aduance ACS Abstracts, February 15, 1994. 0095-233819411634-0421$04.50/0 Fueled by the intense activity in fullerene chemistry and intrinsically interesting geometrical and topological features of fullerenes, several studies have focused on the fascinating mathematical properties of fullerenes. These studies included graph theoretical computations of the characteristic polynomials,...
