The purities of the widely-used herbicide glyphosate (N-(phosphonomethyl)glycine), and the insecticide profenofos (O-(4-bromo-2-chlorophenyl) O-ethyl S-propyl phosphorothioate) were determined by 1 H and 3 1 P quantitative nuclear magnetic resonance (QNMR) spectrometry using ...
Oxidization of O,O,O-trimethyl phosphorothioate to the corresponding oxo (P=O) compound is accomplished under mild conditions with hydrogen peroxide or ozone. Urea hydroperoxide was found to be a serviceable solid-state source of hydrogen peroxide; it was a better oxidizing agent than 30% hydrog...
O,O,S-Trimethyl phosphorothioate (OOS-TMP) is known to induce unique symptoms, which are characterized by hypophagia, progressive weight loss, and hypothermia. To determine whether there is the possibility of a causal relationship between these toxic symptoms and a direct action of OOS-TMP on th...
Geometrical, conformational and spectroscopical properties of three chalcogenphosphates were studied comparatively. Rotational isomerism and conformational flexibility were evaluated for trimethyl phosphate, O,O,O-trimethyl thiophosphate and O,O,O-trimethyl selenophosphate by studying the vibrat...
There is not much level 1 evidence based literature to guide management of hypertrophic scars and keloids despite an array of therapeutic modalities at disposal. Intralesional (i/l) triamcinolone injections have remained a gold standard in non surgical management. Sporadic reports on use of i/l ...
In this work, the potential of waxes for preparing with the ultrasonic spray congealing technique microparticles for controlling the in vitro release of verapamil HCl was investigated. The first part of the study encompassed the optimisation of the formulation to achieve an efficient drug incorp...
Background: Patients with fixed-dose combination product overdoses involving verapamil and trandolapril may present differently than sole calcium channel blocker (CCB) or angiotensin-converting enzyme inhibitor (ACE-I) overdose alone, and may have implications for the toxicological management. T...
Aim To evaluate the safety, effect on breastfeeding and efficacy of a combination of pethidine and levallorphan (Pethilorfan) for pain relief during labor.Methods We compared maternal or neonatal morbidities, suckling difficulties in newborns and breastfeeding rates between 177 women who receive...
The purpose of this study is to evaluate the efficacy and reliability of pharmacologic provocative testing with methohexital (PPTM) using intraoperative neurophysiologic monitoring (IONM) in endovascular embolization procedures (EEPs).111 EEPs cases were retrospectively reviewed between 2014 and...
Es war das Ziel der vorliegenden Untersuchung, zwei intravense Sedierungstechniken mit Propofol (P) oder Methohexital (M) zur elektiven Magnetresonanztomographie (MRT) bei 120 Kindern unter 6 Jahren bezglich Sicherheit, Nebenwirkungen, Aufwachverhalten und Verlegungszeiten zu vergleichen. Jeweil...
Study Objective: To evaluate the effects of alfentanil or lidocaine on the excitatory phenomena (myoclonus, cough, hiccough) caused by methohexital anesthesia and on the hemodynamic changes induced by retrobulbar block.Design: Prospective, randomized, placebo-controlled, double-blind study.Setti...
The purpose of this study was to engineer nanoparticles with various sustained profiles of drug release and prolonged circulation by blending poly(d,l-lactic acid)/poly(d,l-lactic/glycolic acid) (PLA/PLGA) homopolymers and poly(ethylene glycol) (PEG)-block-PLA/PLGA copolymers encapsulating betam...
Tmperature dependence of heat capacity of N-(trimethylsilyl)ethyleneimine, N-(triethylsilyl)-ethyleneimine, N-(dimethylphenylsilyl)ethyleneimine with zinc chloride was studied in the 5-340 K rangein an adiabatic vacuum calorimeter with ∼0.2% error. From the data obtained tge complexes thermodyn...
New materials that can bind and deliver oligonucleotides such as short interfering RNA (siRNA) without toxicity are greatly needed to fulfill the promise of therapeutic gene silencing. Amphiphilic macromolecules (AMs) were functionalized with linear ethyleneimines to create cationic AMs capable ...
We report on an atomic force microscopy study of polyelectrolyte films of poly(ethyleneimine) (PEI), poly(ethylene-co-maleic acid) (PMAE) and poly(styrene sulfonic acid) sodium salt (PSS) deposited by the layer-by-layer electrostatic technique. The organic thin films were prepared either followi...
The pressure dependences of the peaks observed in the micro‐Raman spectra of Prussian blue (Fe4[Fe(CN)6]3), potassium ferricyanide (K3[Fe(CN)6]), and sodium nitroprusside (Na2[Fe(CN)5(NO)]·2H2O) have been measured up to 5.0 GPa. The vibrational modes of Prussian blue appearing at 201 and 365 c...
Three new bistetrahydroisoquinoline marine natural products, renieramycins W (1w), X (1x), and Y (1y), along with two known renieramycins M (1m) and T (1t), were isolated from the pretreated Philippine blue sponge Xestospongia sp. with KCN and their structures were elucidated by comparing their ...
Earlier the probability for the occurrence of quasisinusoidal oscillations in the mammal's brain redox-state potential (E) (4-20 osc/min) recorded by an implanted platinum electrode has been shown to rise during high levels of behavior arousal [T.B. Shvets-Teneta-Gurii, K.Ju. Sarkisova, Change i...
The peroxidase-like activity of cytochrome c is considerably increased by unfolding of the protein. The enhancement of the activity is due to the higher reaction rate of unfolded cytochrome c with hydrogen peroxide, which is the rate-determining step in the peroxidase cycle of cytochrome c (Gębi...
Mn(II)-sodium dodecyl sulphate complex (Mn(II)-SDS) is used to mimic the active group of peroxidase. The catalytic characteristic of this mimic enzyme catalyst in the oxidation reaction of fluorescence substrate, tetraethyldiaminoxanthyl chloride (Pyronine B (PB)), with hydrogen peroxide has bee...
