More than 200 000 ring-width measurements from 384 trees were obtained for 20 individual sites ranging from the lower to upper local timber-lines in the Northwest Karakorum of Pakistan and the Southern Tien Shan of Kirghizia. Samples were obtained predominantly from juniper species (Juniperus) and were analysed to reconstruct regional climatic variation patterns in Western Central Asia since ad...

AIM To test of the implantable-cardioverter-defibrillator is done at the time of implantation. We investigate if any testing should be performed. METHODS All consecutive patients between January 2006 and December 2008 undergoing implantable cardioverter-defibrillator (ICD) implantation/replacement (a total of 634 patients) were included in the retrospective study. RESULTS Sixteen patients (...

γ-Cyclodextrin and an enzyme used in its production do not have a history of food use in the EU which means the novel ingredient falls within the scope of novel food Regulation EC No. 258/97. The application for authorisation of γ-Cyclodextrin as a novel food ingredient was prepared pursuant to Commission Recommendation 97/618/EC concerning the scientific aspects and the presentation of informa...

It is well established that sequence divergence has an inhibitory effect on homologous recombination. However, a detailed analysis of this relationship is missing for most higher eukaryotes. We have measured the rate of somatic recombination between direct repeats as a function of the number, type, and position of divergent nucleotides in Arabidopsis. We show that a minor divergence level of 0....

INTRODUCTION Onodi cells are the most posterior ethmoid air cells and extend superolateral to the sphenoid sinus. These cells are also intimately related with the sphenoid sinus, optic nerve, and carotid artery. Radiologic evaluation is mandatory to assess for anatomic variations before any treatment modalities related to the sphenoid sinus. OBJECTIVE To evaluate the effect of Onodi cells on ...

Benzene molecules, present in the proto-planetary nebula CRL 618, are ionized and dissociated by UV and X-ray photons originated from the hot central star and by its fast wind. Ionic species and free radicals produced by these processes can lead to the formation of new organic molecules. The aim of this work is to study the photoionization and photodissociation processes of the benzene molecule...

The mutL gene of Salmonella typhimurium LT2 is required for dam-dependent methyl-directed DNA mismatch repair. We have cloned and sequenced the mutL gene of S. typhimurium LT2 and compared its sequence with those of the hexB gene product of the gram-positive bacterium Streptococcus pneumoniae and the PMS1 gene product of the yeast Saccharomyces cerevisiae. MutL was found to be quite similar to ...

MicroRNAs (miRNA) are small endogenously expressed non-coding RNAs that negatively regulate expression of protein-coding genes at the translational level. Accumulating evidence, such as aberrant expression of miRNAs, suggests that they play a role in the development of cancer. They have been identified in various tumor types, demonstrating that different sets of miRNAs are usually deregulated i...
