The purpose of this paper is to describe a new, user-friendly tool that will enable researchers and instructors to setup and run virtual environment scenarios that adapt to the VE user’s real-time performance and cognitive status. This tool, the Automated SAF Adaptation Tool (ASAT), will work with existing performance and cognitive state assessment software, and with existing semi-automated for...
Ionizing radiation (IR) induces highly cytotoxic double-strand breaks (DSBs) and also clustered oxidized bases in mammalian genomes. Base excision repair (BER) of bi-stranded oxidized bases could generate additional DSBs as repair intermediates in the vicinity of direct DSBs, leading to loss of DNA fragments. This could be avoided if DSB repair via DNA-PK-mediated nonhomologous end joining (NHE...
BACKGROUND H1N1 influenza viruses mutate rapidly, rendering vaccines developed in any given year relatively ineffective in subsequent years. Thus it is necessary to generate new vaccines every year, but this is time-consuming and resource-intensive. Should a highly virulent influenza strain capable of human-to-human transmission emerge, these factors will severely limit the number of people tha...
The aim of this study was to compare the efficacy of D-RaCe files and a self-adjusting file (SAF) system in removing filling material from curved root canals instrumented and filled with different techniques by using microcomputed tomography (micro-CT). The mesial roots of 20 extracted mandibular first molars were used. Root canals (mesiobuccal and mesiolingual) were instrumented with SAF or Re...
Symptomatic burden in myeloproliferative neoplasms is present in most patients and compromises quality of life. We sought to validate a broadly applicable 18-item instrument (Myeloproliferative Neoplasm Symptom Assessment Form [MPN-SAF], coadministered with the Brief Fatigue Inventory) to assess symptoms of myelofibrosis, essential thrombocythemia, and polycythemia vera among prospective cohort...
The yeast Saccharomyces cerevisiae X2180, the strain most commonly used for genetic studies on yeasts, was treated with the mutagen ethyl methanesulfonate, and mutants defective in the synthesis of cell wall mannan were isolated. The initial selection of mutants was made on the basis of their failure to agglutinate with antiserum that was specific for the mannotetraose side chain of the mannan,...
Precipitins to mannan and cytoplasmic antigens of three Candida species were determined in an unselected series of 289 non-pregnant women. Precipitins were present in 20% of sera of women with vaginal candidiasis, in 23% of women harbouring yeasts in the vagina without clinical signs of infection, and in 21% of women harbouring yeasts in sites other than the vagina. Of the 47 patients who react...
Hemodialysis (HD) is the most frequently used treatment for end-stage renal disease. Despite all efforts to improve the outcomes, the mortality of patients on HD is still high, and this is especially related to cardiovascular diseases (CVD). Glucose degradation products accumulate in plasma and tissue; such accumulation is strongly related to the risk of developing CVD. Tissue deposits of advan...
We have obtained evidence for two structurally and antigenically different Saccharomyces cerevisiae cell wall mannans. One, which occurs widely and is found in S. cerevisiae strain 238C, is already known to be a neutral mannan which yields mannose, mannobiose, mannotriose, and mannotetraose on acetolysis of the (1 --> 6)-linked backbone. The other, which was found in S. cerevisiae brewer's stra...
