Left ventricular assist device implantation disrupts the natural intracavitary blood flow path through the heart, introducing flow patterns potentially associated with thrombosis, especially around the inflow cannula. We describe a novel technique for completely excluding the left ventricle with an assist device by using a cone shaped ring-reinforced prosthesis.

Low-calorie sweeteners are considered to be beneficial in calorie control, but the impact of these sweeteners on gastric emptying is not well described. The purpose of this study was to compare the gastric emptying rate of agave nectar with those of glucose and fructose, and to evaluate the interaction of cholecystokinin (CCK)-1, CCK-2 and glucagon-like peptide-1 (GLP-1) receptors in agave-induced alterations in gastric emptying. Female Sprague-Dawley rats were fitted with gastric cannulas. Following the recovery, the gastric emptying rates of glucose, fructose and agave at 12...

Chronic infusion of aldosterone into the 4(th) ventricle (4(th) V) induces robust daily sodium intake, whereas acute injection of aldosterone into the 4(th) V produces no sodium intake. The inhibitory mechanism of the lateral parabrachial nucleus (LPBN) restrains sodium intake induced by different natriorexigenic stimuli and might affect the acute response to aldosterone into the 4(th) V. In the present study, 1.8% NaCl and water intake was tested in rats treated with acute injections of aldosterone into the 4(th) V combined with the blockade of the inhibitory mechanisms with injections of moxonidine (α2 adrenergic/imidazoline agonist) or methysergide (a serotonergic antagonist) into the LPBN...

BACKGROUND: Promoting arousal by manipulating certain brain regions and/or neurotransmitters has been a recent research focus, with the goal of trying to improve recovery from general anesthesia. The current study tested the hypothesis that a single subanesthetic dose of ketamine during isoflurane anesthesia would increase cholinergic tone in the prefrontal cortex and accelerate recovery. METHODS: Adult male rats were implanted with electroencephalography electrodes (frontal, parietal, and occipital cortex) and a microdialysis guide cannula targeted for the prefrontal cortex...

OBJECTIVE: Providing skin-to-skin care (SSC) to preterm infants is standard practice in many neonatal intensive care units. There are conflicting reports on the stability of oxygen saturation (SpO2) during SSC, which may create a barrier to a wider implementation of SSC to infants receiving respiratory support. Regional cerebral oxygenation (rcO2) measured using near-infrared spectroscopy can serve as a surrogate parameter for cerebral oxygen delivery and consumption. We hypothesised that rcO2 during SSC would be similar to standard care in preterm infants receiving respiratory support...

BACKGROUND: Bronchiolitis is a common respiratory illness of early childhood. For most children it is a mild self-limiting disease but a small number of children develop respiratory failure. Nasal continuous positive airway pressure (nCPAP) has traditionally been used to provide non-invasive respiratory support in these children, but there is little clinical trial evidence to support its use. More recently, high-flow nasal cannula therapy (HFNC) has emerged as a novel respiratory support modality...

PURPOSE: To report a novel technique for subretinal fluid drainage in scleral buckle surgery. METHODS: A 26-gauge intravenous cannula with its needle was used to puncture the sclera; then, the needle (metallic part) was withdrawn to further introduce the cannula into the subretinal space. In addition, we describe using the 25-gauge microcannula of the chandelier light to inject the balanced salt solution to help restore the intraocular pressure and push the subretinal fluid through the intravenous cannula under direct visualization...

Oral supplementation of clay to dairy cattle has been reported to reduce toxicity of aflatoxin (AF) in contaminated feed. The objective of this study was to determine the effects of 3 concentrations of dietary clay supplementation in response to an AF challenge. Ten multiparous rumen-cannulated Holstein cows [body weight (mean ± SD) = 669 ± 20 kg and 146 ± 69 d in milk], were assigned to 1 of 5 treatments in a randomized replicated 5 × 5 Latin square design balanced to measure carryover effects. Periods (21 d) were divided in an adaptation phase (d 1 to 14) and a measurement phase (d 15 to 21)...

BACKGROUND: Fiberoptic tracheo-bronchoscopy is the most commonly used procedure for percutaneous dilational tracheotomy (PDT). However, PDT can be associated with major complications, including death. Furthermore it is unclear, whether the tracheal ring fractures may contribute to the development of tracheal stenosis after PDT nor whether tracheal ring fractures can be prevented by using a rigid endoscope for this procedure. The purpose of this study was to evaluate the feasibility of and the incidence of complications for PDT using the rigid tracheotomy endoscope (TED)...
