The DNA polymerase 4 protein (Pol4) of Saccharomyces cerevisiae is a member of the X family of DNA polymerases whose closest human relative appears to be DNA polymerase lambda. Results from previous genetic studies conflict over the role of Pol4 in vivo. Here we show that deletion of Pol4 in a diploid strain of the SK1 genetic background results in sensitivity to methyl methanesulfonate (MMS). ...
Sorting is a primitive operation that is a building block for countless algorithms. As such, it is important to design sorting algorithms that approach peak performance on a range of hardware architectures. Graphics Processing Units (GPUs) are particularly attractive architectures as they provides massive parallelism and computing power. However, the intricacies of their compute and memory hier...
The nature of DNA sequence changes induced by methyl methanesulfonate (MMS) at the vermilion locus of Drosophila melanogaster was determined after exposure of postmeiotic male germ cell stages. MMS is a carcinogen with strong preference for base nitrogen alkylation (s = 0.86). The spectrum of 40 intralocus mutations was dominated by AT----GC transitions (23%), AT----TA transversions (54%) and d...
BACKGROUND Ovarian cancer has a poor prognosis, with just 40% of patients surviving 5 years. We designed this trial to establish the effect of early detection by screening on ovarian cancer mortality. METHODS In this randomised controlled trial, we recruited postmenopausal women aged 50-74 years from 13 centres in National Health Service Trusts in England, Wales, and Northern Ireland. Exclusi...
Bile salt/phospholipid mixed micelles (MMs) are potent carriers used for oral absorption of drugs that are poorly soluble in water; however, there are many limitations associated with liquid formulations. In the current study, the feasibility of preparing bile salt/phospholipid MM precursor (preMM) pellets with high oral bioavailability, using fluid-bed coating technology, was examined. In this...
UNLABELLED BACKGROUND Although soybeans have the ability to attenuate insulin resistance, it is insufficient to alleviate type 2 diabetic symptoms and different types of fermented soybeans may have even better anti-diabetic effects. Meju, unsalted fermented soybeans exhibited better insulin sensitizing and insulinotropic actions than unfermented cooked soybeans (CSB). We investigated whether...
In micropropagation of Anthurium the most important and sensitive stage, is callus induction from explant. This experiment was conducted in a completely randomized design with factorial arrangement in 4 replications in Sari Agriculture Sciences and Natural Resources University (SANRU) in 2010. The cultivar used in this study is Fire and leaf segments with and without main nervure, were used as ...
Real-world stressors are complex and multimodal, involving physical, psychological, and social dimensions. However, the brain networks that mediate stress responses to these stimuli need to be further studied. We used c-Fos mapping in mice to characterize brain circuits activated by exposure to a single episode of multimodal stress (MMS), and compared these to circuits activated by electric foo...
This study compares the use of tangential flow filtration (TFF), normal flow filtration and modified Moore swabs (MMS) for the concentration and detection of Salmonella, spiked at 1-760 CFU l(-1), from 10 l of surface water. Two immunomagnetic separation (IMS) methods, Pathatrix and Dynabeads, for further concentration of Salmonella were compared following filtration and overnight enrichment. D...
The nuclease halo mutant, nuh-4, of Neurospora crassa was identified conclusively as an allele of uvs-3, a gene involved in error-prone DNA repair. Like uvs-3, nuh-4 showed spontaneous mutator effects, and any previous contradictory findings were found to be due to newly arisen mutants. In normal strains the two alleles are noncomplementing and indistinguishable for sensitivity to UV and methyl...
