Breakthrough cancer pain (BTCP) is defined as a transient exacerbation of pain that arises in patients with otherwise controlled persistent pain. BTCP typically has a rapid onset and relatively short duration, but it causes a significant amount of physical and psychological distress for patients. Several rapid-onset fentanyl formulations have been introduced in the USA to replace traditional or...

Evaluation of insecticidal activity of flea products is generally based on counting live fleas in the animal's coat 24 and 48 hours following artificial infestation. This approach, however, does not allow to specify whether the fleas have had the opportunity to bite and take a bloodmeal prior to their death. To address this question, 30 cats were alloted to six groups of five animals. Each cat ...

We measured the manganese content of whole blood, plasma, platelets, mononucleated cells, polymorphonucleated cells, and erythrocytes. Platelets and blood cells were separated from whole blood by use of discontinuous gradients of colloidal polyvinylpyrrolidone-coated silica (Percoll), and their manganese content was measured by Zeeman graphite furnace atomic absorption spectrophotometry, after ...

avoiding cytolysis or membrane disruption. After incuba tion, the mixtures were centrifuged, and 105,000 x g supernatants were subjected to gel filtration. The macromolecular peak fractions thus obtained contained about 2% radio activity of the whole cells or 50% radioactivity of the plasma membranes. They showed several physical and chemical features characteristic of acid mucopolysaccharides....

Oxytocin (OT) in the central nervous system (CNS) influences social cognition and behavior, making it a candidate for treating clinical disorders such as schizophrenia and autism. Intranasal administration has been proposed as a possible route of delivery to the CNS for molecules like OT. While intranasal administration of OT influences social cognition and behavior, it is not well established ...

Hot corrosion performance of Atmospheric Plasma Spray (APS) and Detonation spray (DSC) CoCrAlY, NiCoCrAlY, NiCr coatings on T91 steel were investigated at 650 °C for 100 cycles under Na2SO4-K2SO4-Fe2O3 mixed salt deposit in ambient air. The hot resistance DSC was found to be superior their APS counterparts. Chromia spinel oxides provided excellent while no ?-Al2O3 observed. NiCoCrAlY offered th...

Sealing treatment is a post-surface of the plasma spray coating process to improve corrosion resistance material. In this study, effect sealing on and adhesive strength spray-coated alumina coatings was analyzed. For sealing, an epoxy resin applied surface coated specimen using brush. The subjected salt test for up 48 hours microstructural analysis revealed that in layer/base material interface...

The potential for a pharmacokinetic interaction between butorphanol nasal spray and cimetidine, under steady state conditions, was evaluated in 16 healthy male volunteers. Subjects received either a 1 mg butorphanol nasal spray every 6 h or a 300 mg cimetidine tablet every 6 h on days 1 4, the combination of two compounds every 6 h on days 5-8 and the original treatment as described in the firs...

Ti6Al4V alloys are widely used in chemical plants, automobile, aerospace industries and medical applications (bone, dental) because of its high specific strength. But, it has poor wear resistance. In the present investigation, duplex coatings were employed to enhance the mechanical and tribological properties. WC-Co Ceramic coatings were deposited on Ti6Al4V substrate with different thicknesses...
