Global sensitivity analysis (GSA) is a valuable tool to support the use of mathematical models for environmental systems. During the last years the water quality modelling field has embraced the use of GSA. Environmental water quality modellers have tried to transfer the knowledge and experience acquired in other disciplines. The main objective of this paper is to provide an informed problem st...

Nontutimorous decrease in 99mTc-GSA accumulation has not been well covered in the literature. Understanding of this phenomenon is, however, essential for accurate evaluation of regional hepatic function. Scintigrams (transaxial SPECT) of 269 patients who underwent 99mTc-GSA liver scintigraphy were reviewed for the presence of nontumorous decreases in 99mTc-GSA accumulation. Nontumorous decrease...

Correlation was greater than 90% between feline leukemia virus (FeLV), group-specific antigen (GSA) in leukocytes, and viral infectivity (VI) in serum or plasma from 132 cats infected with either the Rickard strain of FeLV, the Snyder-Theilen strain of feline sarcoma virus, or field strains of FeLV. Detection of GSA in blood cells was at least as sensitive as detection of VI in serum. In 45% of...

The gravitational search algorithm (GSA) is a kind of swarm intelligence optimization algorithm based on the law of gravitation. The parameter initialization of all swarm intelligence optimization algorithms has an important influence on the global optimization ability. Seen from the basic principle of GSA, the convergence rate of GSA is determined by the gravitational constant and the accelera...

(99m)Tc-galactosyl human serum albumin (GSA) scintigraphy is useful to evaluate hepatic function and hepatic functional reserve. A reliable SPECT and CT integrated system is now commercially available. Using this system, we can obtain (99m)Tc-GSA SPECT/CT fused imaging with a small registration error. Therefore, the (99m)Tc-GSA scintigraphy techniques prove more useful in clinical practice than...

489 Abstract: The presence and distribution of Griffonia Simplicifolia I-B4 (GSA I-B4) and Calcitonin Gene Related Peptide (CGRP) were studied in the nodose ganglion (NG) (inferior ganglion of the vagus nerve), sphenopalatine ganglion (SPG) and superior cervical ganglion (SCG) of the rat. GSA I-B4 labeling was found in all ganglia tested. Neither SPG nor SCG cell bodies stained with CGRP were u...

Gene set analysis (GSA) is useful in interpreting a genome-wide association study (GWAS) result in terms of biological mechanism. We compared the performance of two different GSA implementations that accept GWAS p-values of single nucleotide polymorphisms (SNPs) or gene-by-gene summaries thereof, GSA-SNP and i-GSEA4GWAS, under the same settings of inputs and parameters. GSA runs were made with ...

Guanidinosuccinic acid (GSA) has been isolated in substantial quantities from the urine of uremic patients (I). Attempts to form this compound by transamidination from canavanine and arginine to aspartic acid were unsuccessful. A possible pathway has been found for GSA formation. Human liver homogenate splits canavaninosuccinic acid (CSA) to form homoserine and GSA. Optimum pH is at 8.7-8.8. Th...
