Background and Aims: Wild-type RS-12 strain of mumps virus has been isolated from an Iranian patient and has been attenuated after several serial passages. This study was designed to determine nucleotide and amino acid substitutions in the HN, F and SH genes during attenuation of the wild-type virus. Materials and Methods: Required viral samples prepared at Razi Vaccine and Serum Institute. Vi...
Drought is a major factor limiting growth and development of crops such as mung bean (Vigna radiate (L.) wilczek) in arid and semi-arid regions of the world. This study was conducted to investigate the effects of different timing and severity of drought stress on physiological traits of mung bean and its relation to grain yield. A field experiment was carried out during 2004 growing season at E...
Repetition suppression (RS) is a reduction of neural response that is often observed when stimuli are presented more than once. Many functional magnetic resonance imaging (fMRI) studies have exploited RS to probe the sensitivity of cortical regions to variations in different stimulus dimensions; however, the neural mechanisms underlying fMRI-RS are not fully understood. Here we test the hypothe...
Circumstances that compromise efficient DNA replication, such as disruptions to replication fork progression, cause a state known as DNA replication stress (RS). Whereas normally proliferating cells experience low levels of RS, excessive RS from intrinsic or extrinsic sources can trigger cell cycle arrest and senescence. Here, we report that a key driver of RS-induced senescence is active downr...
BACKGROUND/PURPOSE To assess correlation between brain lesions and clinical status with 1.5T and 3T magnetic resonance imaging (MRI). METHODS Brain MRI fluid-attenuated inversion-recovery (FLAIR) sequences were performed in 32 multiple sclerosis (MS) patients. Expanded Disability Status Scale (EDSS) score (mean±standard deviation) was 2±2.0 (range 0-8), disease duration 9.3±8.0 (range .8-29) ...
0146 In our recent Letter there appeared several errors in printing. On p. 573, the title should read as follows: ‘‘Diffraction tomography for biomedical imaging with diffuse-photon density waves.’’ Notice that it is biomedical not biochemical. On p. 573, line 6 in the second paragraph in the left-hand-side column, ‘‘In this Letter present a . . .’’ should read as ‘‘In this Letter we present a ...
Between 2001–2003 Paik and others, from a US-based multiinstitutional clinical trials group (the NSABP) that includes many Canadian centres, developed an assay to identify 21 genes from tumour samples that collectively significantly predicted patients’ outcomes (recurrences, breast cancer deaths, and response to chemotherapy).1 The 21-gene assay was based on advances in genetic techniques, refi...
