Development of a smart bolus system for multi-parameter monitoring of bovine welfare
… monitoring tools like wearable devices and smart boluses, current technologies are limited in providing comprehensive, real-time insights into bovine welfare. This research addressed that gap in currently available technologies, by developing a prototype PULSE (Portable Unit for Lab-on-Site …

Development of 3D-Printed Patient Specific Bolus For Clinical Use In to tal Scalp Irradiation
… homogeneity, to the point where non-conformal bolus is now a limiting factor. Bolus is required to build-up full dose to the scalp surface in total scalp irradiation. Creating bolus that is conformal to the scalp is technically challenging due to the convex curvature of the scalp, and most …

Effects of a sustained-release copper bolus on growth and reproductive traits of beef bulls
… the effects of sustained -release copper (Cu) boluses on growth and reproductive traits of beef bulls. Two groups of bulls were used in consecutive years (n=26 in experiment 1; n=20in experiment 2). Bulls in each experiment were allotted by weight and breed into two equally numbered treatment …

Predicting blood pressure response to fluid bolus therapy in the ICU using attention-based stacked neural networks for clinical interpretability
Fluid bolus therapy (FBT) is a treatment commonly administered to treat seriously ill hypotensive patients in intensive care units (ICUs). Unfortunately, only a fraction of hypotensive patients respond positively to FBT, and emergency room physicians are constantly challenged in determining whether …

The safety and efficacy of the propofol/ Alfentanil/ Ketamine-bolus technique in midazolam pre-medicated patients undergoing office based plastic or reconstructive surgery
The purpose of this research project was to assess the safety and efficacy of a combination of drugs for conscious sedation in patients undergoing office-based plastic and reconstructive surgery. A pilot study was done to determine the safety of the co-administration of the drugs used in the …

A pilot study on the effects of a yeast probiotic on sow and piglet behavior and well-being
… were to: (a) evaluate the effects of feeding a bolus of yeast Saccharomyces boulardii (yeast probiotic) to sows during gestation and lactation on her behavior and well-being as well as her piglets’ well-being, and (b) assess the effects of weaning stress on piglets from sows that were fed …

A randomised comparison of bolus phenylephrine and ephedrine for the management of spinal hypotension in patients with severe preeclampsia and a non-reassuring fetal heart rate trace
… fetal heart tracing were randomised to receive bolus ephedrine (7.5-15 mg) or phenylephrine (50-100 μg) for spinal hypotension. The primary outcome was umbilical arterial base deficit. Secondary outcomes were umbilical arterial (UA) and venous (UV) pH and lactate level, venous base deficit, and …

Temporal case-based reasoning for insulin decision support
… one aspect of which is the administration of bolus insulin. Formulas exist to estimate the required bolus, and have been adopted by existing mobile expert systems. These formulas are shown to be eective but are unable to automatically adapt to an individual. This research resolves the …

Cardiovascular and Hematological Effects of Hetastarch and Hypertonic Saline Solutions During Experimental Endotoxemia in Horses
… endotoxin infused at 50 ug/kg; divided into a bolus infusion of 20 ug/kg followed by 30 ug/kg given over 30 minutes. After induction of endotoxic shock; group I (control) received a bolus (15 ml/kg) of isotonic solution, group II (isotonic solution) received a bolus (60 ml/kg) of balanced …

Quantification of cardiac magnetic resonance imaging perfusion in the clinical setting at 3T
… parameter (DP) modelling are compared in single bolus versus dual bolus analysis. For model-based myocardial blood flow quantification, the convolution of a model with the arterial input function (i.e. contrast agent concentration-time curve extracted from the left ventricular cavity) is fitted …

Evaluating The Relationship Between Diadochokinesis And Severity Of Dysphagia As It Relates To Forced Vital Capacity In Individuals With Amyotrophic Lateral Sclerosis
… function was assessed with three thin liquid boluses of increased volume, two 5mL pudding boluses and one piece of graham cracker. Pharyngeal residue, PAS and number of swallows per bolus was rated by two independent investigators. Between-group findings included significant impairment in …

Investigations into the use of continuous low-level medication for the control of helminths in the ruminant
… Section 2, the development of an intra-ruminal bolus incorporating thiophanate and designed to release drug at a predetermined rate over an extended period of time is described. Experiments were carried out in sheep to assess the bolus density required for retention within the reticulo-rumen …

Association of lingual myoarchitecture with local mechanics during swallowing determined by magnetic resonance imaging
… to first configure and then transport the bolus from the oral cavity to the pharynx during swallowing. In order to observe the synergistic interactions of the eight different muscles in the tongue, MRI techniques were used to determine the three-dimensional fiber architecture, measure the …

Antimicrobial pharmacodynamics: The gentamicin - Escherichia coli relationship
… duration of exposure following continuous and IV bolus dose simulations. Significant bacterial killing first occurred at gentamicin concentrations equal to 1/2 the MIC. Exposure to drug concentrations between 1/2 and 2 $\times$ the MIC resulted in a 99.9% loss of viability, followed by resistant …

Automated perfusion-weighted MRI metrics via localized arterial input functions
… calculating cerebral blood flow by tracking a bolus of contrast agent. Past methods to do this calculation require human intermediaries and can lead to errors in the presence of delay and dispersion of the contrast bolus, situations which occur commonly in the pathological conditions which …

The Impact of Insulin Management on Quality of Life in Type 2 Diabetes
… optimally achieved by using intensive, or basal-bolus, insulin management. The quality of life (QOL) effects of basal-bolus insulin management are not fully known. This cross-sectional, observational study was based on the Revised Wilson and Cleary Model for Health Related Quality of Life, which …
