NADH and Ca2+ have important regulatory functions in cardiomyocytes related to excitation-contraction coupling and ATP production. To elucidate elements of these functions, we examined the effect of NADH on sarcoplasmic reticulum (SR) Ca2+ release and the mechanisms of this regulation. Physiological concentrations of cytosolic NADH inhibited ryanodine receptor type 2 (RyR2)-mediated Ca2+-induce...

Analysis of apple tree phytosanitary state showed that the species composition phytophage mites is labile and subject to a constant shift share ratio. In 2012-2013, orchards Crimea were dominated by Amphytetranychus viennensis Zacher. Its in acarocomplex was 80%. Since 2014, ratio has changed towards prevalence Panonychus ulmi Koch. - 50%. With this, A. decreased 25.0%. some years there mass re...

objective(s): the adverse effects of pyridaben on reproductive system in male animals are not well established. this study was designed to elucidate how pyridaben can effects the histomorphometric, hormonal alternations and reproductive functions of balb/c mice .   materials and methods : for this study, 80 adult and apparently healthy male balb/c mice were divided into three groups viz, contro...

The citrus red mite, Panonychus citri (McGregor), is a global citrus pest, and has developed severe resistance to several types of acaricides. However, the molecular mechanisms of resistance in this mite remain unknown. In this study, seven full-length cDNAs encoding glutathione S-transferases (GSTs) genes were identified and characterized in P. citri. The effects of pyridaben and fenpropathrin...

The photolytic degradations of imidacloprid, carbofuran, diazinon, chlorpyrifos, pyridaben, propoxur, and esfenvalerate were independently compared in both moist (75% field moisture capacity at 0.33 bar) and air-dry microbially viable soils at 5 microg/g. All compounds were applied to sandy soil except for propoxur, which was applied to sandy loam soil. Diazinon was applied to both sandy soil a...

This study reports three novel (18)F-labeled pyridaben analogues for potential myocardial perfusion imaging (MPI). Three precursors and the corresponding nonradioactive compounds were synthesized and characterized. The radiolabeled tracers were obtained by substituting tosyl with (18)F. The total radiosynthesis time of these tracers was 70-90 min. Typical decay-corrected radiochemical yields we...

The tomato russet mite, Aculops lycopersici (Massee, 1937) (Acari: Eriophyidae) is a common pest of tomatoes. predatory Amblyseius swirskii Athias-Henriot, 1962 Phytoseiidae), can control A. populations. To integrate biological and chemical lycopersici, side effects the lethal concentrations acaricides, as predator, on should be considered. 14 acaricides for were determined under laboratory con...
