one important application of fiber reinforced polymer (frp) is to confine concrete as frp jackets in seismic retrofit process of reinforced concrete structures. confinement can improve concrete properties such as compressive strength and ultimate axial strain. for the safe and economic design of frp jackets, the stress-strain behavior of frp-confined concrete under monotonic and cyclic compress...

under prolonged diabetic conditions, hba1c is produced from normal hemoglobin (hba0) through a non-enzymatic glycosylation or glycation, a process which enhances the hemoglobin susceptibility to be auto-oxidized to methemoglobin (methb). here we are reporting that the non-enzymatic reaction between fructose and methb (methb fructation) induces significant changes in the globin structure and deg...

Cyclic bis(3'-5')diguanylic acid (cyclic-di-GMP) functions as a second messenger in diverse species of bacteria to trigger wide-ranging physiological changes. We measured cyclic-di-GMP and its structural analogs such as cyclic bis(3'-5')guanylic/adenylic acid (cyclic-GpAp), cyclic bis(3'-5')guanylic/inosinic acid (cyclic-GpIp) and monophosphorothioic acid of cyclic-di-GMP (cyclic-GpGps) for eff...

Cyclic AMP and cyclic GMP were released into the growth medium of mycelia of Neurospora crassa wild-type strains St.L.74A and Em5297a and by white collar-1 and white collar-2 mutant strains. After growth for 6 days at 18 degrees C, there were 2.19 (St.L.74A), 5.83 (Em5297a), 1.38 (white collar-1), and 1.10 (white collar-2) nanomoles of cyclic AMP per gram dry weight of mycelia in the growth med...

Ajwain is one of the medicinal plants, which the highest composition is thymol, as a strong antioxidant respect to the obtained chromatograms of GC/MS. The antioxidant activity of the Ajwain is measured by square wave voltammetry method and cyclic voltammetry method and 2, 2-Diphenyl-1-picrylhydrazyl (DPPH) method in at the specific concentrations of 1%, 1.5%, 2% and 2.5% and constant pH. The r...

A cyclic AMP-binding protein with a native molecular weight calculated to be 82,000 was purified 2,000-fold from Neurospora crassa. The apparent subunit molecular weight was 47,000 by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, suggesting that the native protein exists as a dimer of identically sized subunits. The 8-N3-cyclic [32P]AMP-labeled protein appeared as a doublet upon tw...

Adenosine-3',5'-cyclic monophosphate was shown to be the compound found in Escherichia coli responsible for the attraction of the amoebae of the cellular slime mold Dictyostelium discoideum. A number of other nucleotides were tested and the following were active: tubercidin-3',5'-cyclic monophosphate, N(6)-2'-O-dibutyryl-adenosine-3',5'-cyclic monophosphate, 5'-methylene adenosine-3',5'-cyclic ...
