citicoline is a natural substance with neuroprotective and repairing effects. it can also increase the phosphor metabolites in cerebral cortex. regarding the various effects of citicoline on central nervous system, this research aims at studying the effects of citicoline on the thiopental sodium anesthesia. six dogs were anesthetized by intravenous injection of 20 mg ∕ kg of 2.5% thiopental sod...

With good mechanical and thermal properties, elastomers having appreciable electrical conductivity may potentially be developed as smart materials for applications such strain sensors, artificial muscles or flexible biosensors. in mind, the purpose of this study was to investigate structure-properties relationships new vulcanised blends a poly (epichlorohydrin) elastomer (PECH) electrically-con...

Conjugated polymer actuators have potential use in implantable neural interface devices for modulating the position of electrode sites within brain tissue or guiding insertion of neural probes along curved trajectories. The actuation of polypyrrole (PPy) doped with dodecylbenzenesulfonate (DBS) is characterized to ascertain whether it can be employed in the cerebral environment. Microfabricated...

Stem cell function is regulated by intrinsic as well as microenvironmental factors, including chemical and mechanical signals. Conducting polymer-based cell culture substrates provide a powerful tool to control both chemical and physical stimuli sensed by stem cells. Here we show that polypyrrole (PPy), a commonly used conducting polymer, can be tailored to modulate survival and maintenance of ...

objective studies on the effect of various antiepileptic drugs on serum lipids show contradictory results. we aimed to find the effect of phenobarbital and sodium valproate monotherapy on serum lipid profile and liver function tests in epileptic children. materials & methods this cohort study was conducted in amirkola children hospital. one hundred and ten children with epilepsy were included i...

Pesticide spray drift has been a worldwide concern in terms of potential environmental pollution and ecosystem damage. This study defined the main reduction agent (DRA) characteristics that help to understand formation process agricultural spraying. Seven various DRAs water were evaluated. Three solutions created based on following materials: calcium dodecylbenzenesulfonate, benzenesulfonic aci...

a simple and efficient one-pot method for the preparation of aromatic iodides has been developed by sequential diazotization–iodination of aromatic amines employing sodium nitrite and sodium iodide in the presence of acidic ionic liquid n-methyl-2-pyrrolidonum hydrosulfate ([h-nmp]hso4). the diazonium salts that are formed by this ionic liquid are stable at room temperature and react rapidly wi...

thiopental sodium is an ultra short-acting barbiturate. due to its redistribution characteristic, its first injection has a short term effect. in order to elongate its anesthesia duration, more injections are needed. as these additional injections extend the recovery length , weaken respiration and causes other dangerous effects; its repeated use is considered unsafe. citicoline is a natural su...
