We show that PFA implies that every perfect pre–image of ω1 of countable tightness contains a closed copy of ω1.
most specialists in the field of foreign language teachingconsiderreading skill as an interactive process between the reader’s prior knowledge and the text.accordingly, the activation of prior knowledge for an effective comprehension is very important. it is generally agreed that the pre-reading phase is the stage where this type of interaction and activation may be enhanced throughcertain stra...
Mitochondrial DNA (mtDNA) is vulnerable to mutations, and the number of copies of mtDNA per cell may increase to compensate for DNA damage. Case-control studies have reported associations between altered mtDNA copy number and risk of renal cell carcinoma (RCC); however, this association has not been investigated prospectively. We conducted a nested case-control study (252 cases and 504 controls...
Background: Polycystic ovary syndrome (PCOS) is an endocrine disorder diagnosed by anovulation hyperandrogenism.Hyperandrogenism increases apoptosis, which will eventually disturb follicular growth in PCOS patients.Since mitochondria regulate apoptosis, they might be affected by high incidence of follicular atresia. This may causeinfertility. Since vitamin D3 has been shown to...
Cloud computing has become a hot technology. The virtualization technology, one of its core support technologies, is also developing quickly. In recent years, a lot of research and practice have been done in the virtualization field. Live virtual machine migration has drawn much attention as a representative technology of the virtualization field. This paper summarizes the research progress of ...
Mitochondrial DNA (mtDNA) copy number in peripheral blood is associated with increased risk of several cancers. However, data from prospective studies on mtDNA copy number and breast cancer risk are lacking. We evaluated the association between mtDNA copy number in peripheral blood and breast cancer risk in a nested case-control study of 183 breast cancer cases with pre-diagnostic blood samples...
A combination of point mutations disrupting both stem 1 and stem 2 of U5 snRNA (U5AI) was found to confer a thermosensitive phenotype in vivo. In a strain expressing U5AI, pre-mRNA splicing was blocked before the first step through an inability of the mutant U5 snRNA to efficiently associate with the U4/U6 di-snRNP. Formation of early splicing complexes was not affected in extracts prepared fro...
We report on a novel role for a pre-mRNA splicing component in genome stability. The Hpr1 protein, a component of an RNA polymerase II complex and required for transcription elongation, is also required for genome stability. Deletion of HPR1 results in a 1,000-fold increase in genome instability, detected as direct-repeat instability. This instability can be suppressed by the high-copy-number S...
Genetic analysis of molecular markers is critical in tracking the emergence and/or spread of artemisinin resistant parasites. Clinical isolates collected in western Kenya pre- and post- introduction of artemisinin combination therapies (ACTs) were genotyped at SNP positions in regions of strong selection signatures on chromosome 13 and 14, as described in Southeast Asia (SEA). Twenty five SNPs ...
