The cholinergic basal forebrain contributes to cortical activation and receives rich innervations from the ascending activating system. It is involved in the mediation of the arousing actions of noradrenaline and histamine. Glutamatergic stimulation in the basal forebrain results in cortical acetylcholine release and suppression of sleep. However, it is not known to what extent the cholinergic versus non-cholinergic basal forebrain projection neurones contribute to the arousing action of glutamate. To clarify this question, we administered N-methyl-D-aspartate (NMDA), a glutamate agonist, into the basal forebrain in intact rats and after destruction of the cholinergic cells in the basal forebrain with 192 immunoglobulin (Ig)G-saporin...

REVIEW
Ahmed Mohyeldin, J Bradley Elder
The resolution and real-time navigation of intraoperative MRI (iMRI) has been leveraged in neurosurgery. We review frameless stereotactic biopsy platforms and focus on emerging technology integrating intraoperative MRI with frameless stereotaxy. Brain biopsy with iMRI allows for an accurate tissue sample with the ability to correct cannula trajectory during surgery, eliminating misdiagnosis secondary to faulty targeting. This technology allows for a percutaneous approach avoiding large incisions, obviates the need for frozen tissue evaluation, has the potential to reduce unnecessary specimen harvesting and operating room time, and optimizes safety of targeting deep brain lesions...

BACKGROUND: Precise implantation of soft tissue fillers to treat the signs of aging is crucial for patient safety and the best aesthetic outcome. Injections are performed commonly with either needles or cannulas, but quantitative comparative data on precise implantation are still elusive. METHODS: Ten fresh-frozen cephalic foreheads (9 male, 1 female) were injected with radiopaque material using both needles and cannulas. Needle injection relied on a perpendicular transcutaneous approach, whereas cannulas were moved in the supra-periosteal plane until reaching the same location as the needle...

Two methods of collecting milk samples from mastitic bovine mammary quarters were compared. Samples were taken in a consistent order in which standard aseptic technique sampling was done first, followed by insertion of a sterile cannula through the teat canal and collection of a second sample. Microbiological results of those two sampling techniques were compared. Milk samples were analysed using multiplex real-time polymerase chain reaction (PCR). The cannula technique produced a reduced number of microbial species or groups of species per sample compared with conventional sampling...

Acute respiratory distress syndrome (ARDS) is characterized as an acute hypoxemic and/or hypercapnic respiratory failure seen in critically ill patients and is still, although decreased over the past few years, associated with high mortality. Furthermore, ARDS may be a life-threatening complication of H1N1 pneumonia. We report on a 45-year-old spina bifida patient with confirmed H1N1 influenza virus infection causing acute respiratory failure, who was successfully weaned from 42-day veno-venous extracorporeal membrane oxygenation (vv-ECMO) treatment with an excellent outcome...

Femoral arterial cannulation in adult venoarterial (VA) extracorporeal membrane oxygenation (ECMO) predisposes patients to ipsilateral limb ischemia. Placement of a distal perfusion catheter (DPC) is one of few techniques available to prevent or manage this complication. Although frequently used, the indications for and timing of DPC placement are poorly characterized, and no guidelines are available to guide its use. The purpose of this study was to compare the incidences of vascular complications and limb ischemia between patients who did and did not receive a DPC at the time of primary ECMO cannulation...

The management of heart failure patients presenting in a moribund state remains challenging, despite significant advances in the field of ventricular assist systems. Bridge to decision involves using temporary devices to stabilize the hemodynamic state of such patients while further assessment is performed and a decision can be made regarding patient management. We developed a new temporary left ventricular assist system employing a disposable centrifugal pump with a hydrodynamically levitated bearing. We used three adult goats (body weight, 58-68 kg) to investigate the 30-day performance and hemocompatibility of the newly developed left ventricular assist system, which included the pump, inflow and outflow cannulas, the extracorporeal circuit, and connectors...

In non-small cell lung cancer (NSCLC) circulating tumor cells (CTCs) can provide information on patient prognosis and treatment efficacy. Currently CTCs are mostly isolated in vitro from small volumes of patient blood samples. The aim of the study was to assess a medical device for in vivo isolation of CTCs directly from the blood of NSCLC patients. The device was inserted in a cubital vein through a standard cannula for thirty minutes. The interaction of target CTCs with the CellCollector was mediated by an antibody directed against the epithelial cell adhesion molecule...

BACKGROUND: Flexible bronchoscopy (FB) is commonly performed to assess, diagnose, and treat patients with respiratory disease, and is typically performed via transnasal or transoral approaches. FB can be performed via tracheal tubes in patients with tracheostomies; however, the safety and technical feasibility has not been established. The present study evaluates the safety and feasibility of performing FB via tracheal tubes. MATERIALS AND METHODS: A total of 45 patients underwent 56 procedures involving FB via tracheal tubes at a single institution from November 2013 to November 2014 and were included in this retrospective case series...

Eight multiparous periparturient Holstein cows fitted with ruminal cannula were used in a split plot design to evaluate the effects of monensin on plasma glucose metabolism. Diets were top-dressed daily with 0 mg/cow of monensin (control) or 300 mg/cow of monensin (MON) both pre- and postpartum. Plasma glucose kinetic parameters on d -13 ± 2.0 and 19 ± 1.6 relative to parturition were determined by using stable isotopes. Na-1-(13)C3-Propionate (labeled propionate) was infused into the rumen to measure glucose synthesis originating from ruminal propionate, and U-(13)C-glucose (labeled glucose) was injected into the jugular vein to determine total glucose kinetics...
