The effects of music amplitude on participants' response time to randomly presented, unexpected, visual events were investigated. Ninety participants completed a motor-reaction task without music and with music played at 60, 70, or 80 dBA. Males preferred more intense music than females did, with males selecting a comfort level of 72 dBA and females, 66 dBA. However, participants' reaction time...
Diamond Blackfan anemia (DBA) is an inherited erythroblastopenia associated with mutations in at least 8 different ribosomal protein genes. Mutations in the gene encoding ribosomal protein S19 (RPS19) have been identified in approximately 25% of DBA families. Most of these mutations disrupt either the translation or stability of the RPS19 protein and are predicted to cause DBA by haploinsuffici...
Genetic resistance and susceptibility to experimental Lyme arthritis have been linked with the production of interleukin-4 (IL-4) or gamma interferon (IFN-gamma), respectively. To determine the absolute requirement for these cytokines in disease outcome, we compared arthritis development in wild-type, IL-4-deficient (IL-4 degrees ), and IFN-gamma-deficient (IFN-gamma degrees ) mice. While susce...
Diamond-Blackfan Anemia (DBA) is characterized by a defect of erythroid progenitors and, clinically, by anemia and malformations. DBA exhibits an autosomal dominant pattern of inheritance with incomplete penetrance. Currently nine genes, all encoding ribosomal proteins (RP), have been found mutated in approximately 50% of patients. Experimental evidence supports the hypothesis that DBA is prima...

Male DBA/2J mice are approximately 20-fold more susceptible than male C57BL/6J mice to hepatocarcinogenesis induced by perinatal treatment with N,N-diethylnitrosamine (DEN). In order to elucidate the genetic control of hepatocarcinogenesis in DBA/2J mice, male BXD recombinant inbred, D2B6F1 x B6 backcross, and D2B6F2 intercross mice were treated at 12 days of age with DEN and liver tumors were ...
The inbred mouse strain C57BLKS/J (BKS) carrying a mutation of the leptin receptor lepr(-/-) (BKS-db) is a classic mouse model of type 2 diabetes. While BKS was originally presumed to be a substrain of C57BL/6J (B6), it has become apparent that its genome contains introgressed regions from a DBA/2 (DBA)-like strain and perhaps other unidentified sources. It has been hypothesized that the striki...
The DBA/2J mouse is a commonly used animal model in glaucoma research. The eyes of DBA/2J mice show severe age-related changes that finally lead to the degeneration of retinal ganglion cells and the optic nerve. Recent electroretinogram studies identified functional deficits, which suggest that also photoreceptor cells are involved in the pathological processes occurring in the DBA/2J mouse ret...
Previously, we have shown in a model of hypersensitivity pneumonitis that Th1-biased C57BL/6 mice are susceptible and Th2-biased DBA/2 mice are resistant to disease. We also showed that this was explained in part by differential regulation of IL-12 by IL-4. For these reasons, we postulated that C57BL/6 and DBA/2 mice differentially express IL-4. In this study, we show that C57BL/6 immune cells ...
The amount of data collected and used by companies has grown rapidly in size over the last decade. Business leaders are now using Business Intelligence (BI) systems to make effective business decisions against large amounts of data. The growth in the size of data has been a major challenge for Database Administrators (DBAs). The increase in the number and size of databases at the speed they hav...
