Nitric oxide (NO) is a stress-signaling molecule in plants that mediates a wide range of physiological processes and responses to metal toxicity. In this work, various NO modulators (NO donor: SNP; NO scavenger: cPTIO; NO synthase inhibitor: l-NAME; and SNP analogs: sodium nitrite/nitrate and so...
Liquid–liquid equilibrium data have been determined for 1-butyl-pyridinium tetrafluoroborate([Bpy]BF 4 )+ammonium citrate ((NH 4 ) 3 C 6 H 5 O 7 )/trisodium citrate (Na 3 C 6 H 5 O 7 )/sodium succinate (Na 2 ...
Background [18F]BF4 −, the first 18F-labelled PET imaging agent for the sodium/iodide symporter (NIS), was produced by isotopic exchange yielding a product with limited specific activity (SA, ca. 1 GBq/μmol) posing a risk of sub-optimal target-to-background ratios (TBR) in PET images ...
Aryl benzoates are important intermediates with a variety range of applications in organic and bioorganic chemistry. In this article, cross-linked poly (4-vinylpyridine) supported benzoate ion, [P4-VP]PhCO2, is easily prepared and used in an efficient, and simple method for, synthesis of aryl be...
Binodal curves of the aqueous N-ethylpyridinium tetrafluoroborate ([EPy]BF 4 )+trisodium citrate (Na 3 C 6 H 5 O 7 ), [EPy]BF 4 +ammonium citrate tribasic ((NH 4 ) 3 C 6 H 5 O 7 ), [EPy]BF 4 +sodium s...
The results of DSC studies of NaBH4–KBF4 mixtures are presented. It is shown by chemical analysis, XRD analysis, IR spectroscopy, and 11B and 9F MAS NMR that the decomposition of the mixtures starts at ~563 K to yield polyhedral borohydride compounds (predominantly B12H 12 2- ) in the...
The KBH4−NaBF4 mixture was studied by thermal analysis (differential scanning calorimetry). Chemical analysis, X-ray powder diffraction analysis, IR spectroscopy, and 11B and 19F MAS NMR spectroscopy showed that the primary stage of the complex pyrolysis process is a metathesis reaction between ...
This research discusses the charge transfer (CT) complex of 1-benzoylpiperazine (1-BP) as a donor with the π-acceptor of 2, 3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) which has been studied spectrophotometrically in acetonitrile (ACN) at different temperatures. The 1:1 molecular composition of...
Attempted conversion of 4-chloro-5-(N-4-bromobutanoyl)amino-6-phenethylaminopyrimidine (2) to 6-chloro-8-[1-(3-bromo)propyl]-9-phenethylpurine (1) under standard cyclization conditions did not give the targeted product. Instead, an unexpected cyclization occurred to give 6-chloro-5-[1-(3-hydroxy...
The effectiveness of tributyl citrate (TbC) as a plasticizer for polylactide and polyhydroxybutyrate was analysed in order to improve the ductility of these polymers and make them good candidates for food packaging applications. Although the thermal and mechanical properties have been widely stu...
Hydroxyapatite coatings were deposited on the titanium substrate by using various content Na3Cit as an organic modifier in electrolytes. The influence of the Na3Cit on the sizes of the HA crystals during electrolytic deposition was investigated under different molar ratio of Na3Cit to calcium io...
Citrate synthase (CS) catalyses the entry of carbon into the citric acid cycle and is highly‐conserved structurally across the tree of life. Crystal structures of dimeric CSs are known in both “open” and “closed” forms, which differ by a substantial domain motion that closes the substrate‐...
To compare the efficacy of pioglitazone+metformin and clomiphene citrate (CC) with metformin and CC in women with CC-resistant polycystic ovary syndrome (PCOS). Randomized clinical trial (RCT). A university teaching hospital in Cairo, Egypt. One hundred women with CC-resistant PCOS. ...
Although extensive work has been done to elucidate the beneficial and unfavorable effects of gastrointestinal prokinetic agents in humans, little is known on the effects of these agents in horses. In this study, we compared the effects of mosapride, metoclopramide, cisapride, and lidocaine on eq...
To compare the efficacy of rosiglitazone and clomiphene citrate (CC) with metformin and CC in women with CC-resistant polycystic ovary syndrome (PCOS). Randomized controlled trial (RCT). A university teaching hospital in Jeddah, Saudi Arabia. Twenty-five women with CC-resistant PCOS. ...
Catheter‐related blood stream infections may be reduced by interdialytic locking with Taurolidine, a nontoxic antimicrobial agent. A formulation of 1.35% Taurolidine in 4% citrate (TC) is associated with a greater need for thrombolysis to maintain catheter patency than 5000 U/ml heparin. Our ai...
The electrocatalytic oxidation of 1,2,3,4-butanetetrol (meso-erythritol) has been studied on polycrystalline platinum in 0.1 M HClO 4 . A preliminary investigation by cyclic voltammetry, used to determine the optimized conditions of electrolysis, showed that the electro-oxidation of meso...
The reactions leading to dissociation of the metastable enol isomers of 2-butanone have a puzzling feature: why does CH 3 C(OH + )CH 2 CH 2 (2) isomerize to the less stable 2-butanone cation (3) and dissociate to the exclusion of conversion to CH 2 C(OH ...
The reaction of dimeric rhodium precursor [Rh(CO) 2 Cl] 2 with two molar equivalent of 1,1,1-tris(diphenylphosphinomethyl)ethane trichalcogenide ligands, [CH 3 C(CH 2 P(X)Ph 2 ) 3 ](L), where X=O(a), S(b) and Se(c) affords the complexes of the type...
Background, aim, and scope Unsaturated esters are emitted to the atmosphere from biogenic and anthropogenic sources, including those from the polymer industry. Little information exists concerning the atmospheric degradation of unsaturated esters, which are mainly initiated by OH radicals. Limit...
