In formula (12) the factor Op (y, b) in the exponent should be replaced by l2 op (y , b), corresponding to absorption of the wave amplitude by a factor e -d/z% where d denotes the distance traversed through a medium in which the mean free path is h 3 l/Fp . This hss the effect of doubling the crosssection estimate in Eq. (14) to 66 mb <” Cr pN <” 94 mb. There a;e no other changes. We also wish ...
MHC class II (MHCII) determinants play a crucial role in the immune response by presenting antigenic peptides to T cells. Their expression is controlled from compact promoters at the transcriptional level. Pre-assembled regulatory factor X (RFX) and nuclear factor Y (NFY) complexes form a platform on DNA. The class II transactivator (CIITA) can then be recruited through multiple protein-protein...
This review addresses the hypothesis that polyunsaturated fatty acids (PUFA), particularly those of the n-3 family, play pivotal roles as "fuel partitioners" in that they direct fatty acids away from triglyceride storage and toward oxidation and they enhance glucose flux to glycogen. In doing this, PUFA may reduce the risk of enhanced cellular apoptosis associated with excessive cellular lipid ...
This review addresses the hypothesis that polyunsaturated fatty acids (PUFA), particularly those of the (n-3) family, play pivotal roles as "fuel partitioners" in that they direct fatty acids away from triglyceride storage and toward oxidation, and that they enhance glucose flux to glycogen. In doing this, PUFA may protect against the adverse symptoms of the metabolic syndrome and reduce the ri...
Pancreatic ?-cell mass and insulin secretion are determined by the dynamic change of transcription factor expression levels in response to altered metabolic demand. Nuclear factor-Y (NF-Y) is an evolutionarily conserved playing critical roles multiple cellular processes. However, physiological role NF-Y pancreatic ?-cells poorly understood. The current study was undertaken a conditional knockou...
UNLABELLED Publications form the knowledge base of any profession. Patterns in professional publications provide insight into the profession's maturity and global status. To our knowledge, publication productivity in nuclear medicine technology has not been reported. A recent study on publication productivity in radiography and radiation therapy provided interesting insight; however, a sampling...
Background and objective: Clear Cell Renal Cell Carcinoma (CCRCC) is the most common adult renal neoplasm. Staging and grading of RCC are important predictors of survival. Fuhrman nuclear grading is widely used for CCRCC, the subjective nature of which has prompted more objective methods to evaluate nuclear features. Furthermore, Ki-67, a reliable marker of cellular pr...
SVCT2 (sodium-vitamin C co-transporter 2) is the major transporter mediating vitamin C uptake in most organs. Its expression is driven by two promoters (CpG-poor exon 1a promoter and CpG-rich exon 1b promoter). In the present study, we mapped discrete elements within the proximal CpG-poor promoter responsible for exon 1a transcription. We identified two E boxes for USF (upstream stimulating fac...
The interactions of legumes with symbiotic nitrogen-fixing bacteria cause the formation of specialized lateral root organs called root nodules. It has been postulated that this root nodule symbiosis system has recruited factors that act in early signaling pathways (common SYM genes) partly from the ancestral mycorrhizal symbiosis. However, the origins of factors needed for root nodule organogen...
