The chronotherapy concept takes advantage of the circadian rhythm of cells physiology in maximising a treatment efficacy on its target while minimising its toxicity on healthy organs. The object of the present paper is to investigate mathematically and numerically optimal strategies in cancer chronotherapy. To this end a mathematical model describing the time evolution of efficiency and toxicit...
BACKGROUND AND OBJECTIVES Mivacurium is a short-acting neuromuscular blocker (NMB), with total duration not exceeding 24 minutes. Early publications have reported no significant differences in recovery time, regardless of the route administration. However, clinical experience points out to longer recovery times when the drug is administered in continuous infusion. This study aimed at comparing ...
A syringe infusion pump infuses fluids, medication or nutrients to the circulatory system of the patient. It is generally used intravenously. Syringe infusion pumps can administer fluids in ways that would be impractically expensive or unreliable if performed manually by nursing staff. Advanced versions of these are used in medical applications such as anesthesia injection, during child birth a...
Changes in the volume of the fluid space expanded by i.v. infusion of Ringer's acetate solution have been analysed recently using mathematical models. Data obtained by such analyses allow simulation of the dilution of the plasma volume during infusion of the solution at different rates. To obtain basic kinetic data for such simulations, the plasma dilution-time curves were measured during and a...
The affect infusion model (AIM) is a prominent theory of when current emotional state is expected to influence the interpretation of a social stimulus (situation). We discuss the assumptions in AIM and conclude that its current specification predicts that both deliberation time and situational complexity should lead to affect infusion. The aim of this research was to clarify the relative import...
BACKGROUNDS/AIMS Conventional graft perfusion method using one small-caliber catheter takes a relatively long time for right liver graft perfusion, thus some modification is needed. In this study, we intended to assess the effectiveness of right liver graft perfusion methods through comparison of different infusion catheters. METHODS The study consisted of two parts including one bench experi...
BACKGROUND Convection enhanced delivery (CED) is a technique using infusion convection currents to deliver therapeutic agents into targeted regions of the brain. Recently, CED is gaining significant acceptance for use in gene therapy of Parkinson's disease (PD) employing direct infusion into the brain. CED offers advantages in that it targets local areas of the brain, bypasses the blood-brain b...
the aim of this work is to evaluate the influence of fabrication methods on the com-pressive properties of sandwich composites using both experimental work and numerical simulations. two types of sandwich composites with e-glass/kevlar/polyester resin facings and end-grain balsa wood as core have been produced by vacuum infusion processing (vip) and hand-lay up (hl) method. compression tests on...
BACKGROUND Intracarotid propofol infusion was studied in canines as an experimental basis for application of propofol in the Wada test. METHODS First, efficacy and side-effects of propofol anaesthesia were studied in eight mongrel dogs that received intracarotid and i.v. propofol infusions for 30 min according to a cross-over design. Auditory evoked potentials were used to guide anaesthesia. ...
Since there is no detailed hospital based incident reporting system, this study was designed to evaluate the medication errors associated with infusion pumps in intensive care unit (ICU). The investigation was conducted in a Teaching hospital in the form of a prospective, observational study. A sample size of 43 doses administered to ICU patients was chosen to enable reliable estimate of error ...
