improvement of soil properties through sustainable agriculture requires suitable management of plant residues. this study was conducted to investigate the effect of different types and managements of plant residue on soil physical properties in a field experiment as factorial based on rcbd with three replicates. the first factor was residue type including barley straw and alfalfa residue, and t...

Some biological characteristics of broodstock and juvenile kutum, Rutilus kutum. were investigated using data collected from the estuaries of Tajen and Shirood Rivers (TR and SR) (southern Caspian Sea basin) as well as from the Caspian Sea in 2012. The results showed higher condition factors (CF) in the male broodstocks kutum than those estimated in the female broodstock of both TR and SR. The ...

Chemical modification studies with pyridoxal 5'-phosphate have indicated that lysine(s) appear to be at or near the active site of Escherichia coli glutamine synthetase (Colanduoni, J., and Villafranca, J. J. (1985) J. Biol. Chem. 260, 15042-15050; Whitley, E. J., Jr., and Ginsburg, A. (1978) J. Biol. Chem. 253, 7017-7025). Enzyme samples were prepared that contained approximately 1, approximat...

Malignant hyperthermia (MH) susceptibility is a dominantly inherited disorder in which volatile anesthetics trigger aberrant Ca(2+) release in skeletal muscle and a potentially fatal rise in perioperative body temperature. Mutations causing MH susceptibility have been identified in two proteins critical for excitation-contraction (EC) coupling, the type 1 ryanodine receptor (RyR1) and Ca(V)1.1,...

Type 1 protein phosphatase (PP1) is a negative regulator of cardiac function. However, studies on the status and regulation of sarcoplasmic reticulum (SR)-associated PP1 activity in failing hearts are limited. We studied PP1 activity and protein and mRNA expression of the catalytic subunit of PP1 (PP1C) and protein levels of PP1-specific inhibitors [inhibitor 1 (Inh-1) and inhibitor 2 (Inh-2)] ...

in order to study the effects of conventional and conservation tillage with management residue on wheat physiological properties, a field experiment was conducted in 2013-2014 at mashhad agricultural and natural resources research center of razavi khorasan province. this experiment was carried out as split plot design based on a randomized complete block design with three replications. main plo...

SR-PSOX in Cultured Aortic Smooth Muscle Cells and Umbilical Endothelial Cells To the Editor: In the November issue of Arteriosclerosis, Thrombosis, and Vascular Biology, Minami et al1 demonstrated expression of the novel scavenger receptor for phosphatidylserine and oxidized lipoprotein (SR-PSOX) in lipid-laden macrophages accumulated in the intima of human atherosclerotic lesions. Because SR-...
