This paper describes an agricultural model (Roth-CNP) that estimates carbon (C), nitrogen (N) and phosphorus (P) pools, pool changes, their balance and the nutrient fluxes exported from arable and grassland systems in the UK during 1800-2010. The Roth-CNP model was developed as part of an Integrated Model (IM) to simulate C, N and P cycling for the whole of UK, by loosely coupling terrestrial, hydrological and hydro-chemical models. The model was calibrated and tested using long term experiment (LTE) data from Broadbalk (1843) and Park Grass (1856) at Rothamsted...

INTRODUCTION: A significant increase of the p-wave of a real-time intracavitary electrocardiography is a reliable and safe method to confirm the central venous catheter tip position close to the atrium. However, conflicting data about the feasibility of electrocardiography exist in patients with atrial fibrillation. METHODS: An observational prospective case-control cohort study was set up to study the feasibility and accuracy of the electrocardiography-controlled central venous catheter tip placement in 13 patients with atrial fibrillation versus 10 patients with sinus rhythm scheduled for elective surgery...

OBJECTIVES: Lumbar punctures (LPs) are commonly performed in febrile infants to evaluate for meningitis, and local anesthesia increases the likelihood of LP success. Traditional methods of local anesthesia require injection that may be painful or topical application that is not effective immediately. Recent advances in needle-free jet injection may offer a rapid alternative to these modalities. We compared a needle-free jet-injection system (J-Tip) with 1% buffered lidocaine to topical anesthetic (TA) cream for local anesthesia in infant LPs...

We report a rare complication of right brachiocephalic vein perforation during ultrasound-guided cannulation of the right internal jugular vein (IJV) in a patient with a tortuous common carotid artery (CCA). We suspect that the tortuous CCA displaced the IJV, which caused misplacement of the J-tip guidewire into the subclavian vein. The stiff dilator sheath introduced over the guidewire then perforated the wall of the brachiocephalic vein, causing massive hemothorax. This was diagnosed by videothoracoscopy...

PURPOSE: To evaluate the efficacy of needle-free jet lidocaine (J-tip) administration for pain reduction in trigger finger corticosteroid injection compared with simultaneous lidocaine injection with corticosteroid. METHODS: A prospective randomized clinical trial was performed in which patients received either 0.25 mL of 2% lidocaine administered by J-tip just prior to 0.5 mL of corticosteroid injection by needle or 0.5 mL of 1% lidocaine and 0.5 mL of corticosteroid administered simultaneously through a needle for the treatment of trigger finger...

BACKGROUND: "Needle pokes" are the most frequent cause of pain encountered by pediatric patients in the hospital setting. Poor control of pain during needle pokes leads to short- and long-term adverse outcomes for both patients and hospitals. J-Tips are a needle-free injection system that use pressurized gas to inject lidocaine in a fine stream of fluid that penetrates the skin. This study undertook an evaluation of their effectiveness at decreasing the pain of the needle poke that takes place with IV insertion...

Effective strategies to reduce phosphorus (P)-enrichment of aquatic ecosystems require accurate quantification of the absolute and relative importance of individual sources of P. In this paper, we quantify the potential significance of a source of P that has been neglected to date. Phosphate dosing of raw water supplies to reduce lead and copper concentrations in drinking water is a common practice globally. However, mains water leakage (MWL) potentially leads to a direct input of P into the environment, bypassing wastewater treatment...

Central venous catheter (CVC) insertion rarely causes cardiac tamponade due to perforation. Although it is a rare complication, it can be lethal if not identified early. We report a case of cardiac tamponade caused by internal jugular (IJ) central venous catheter (CVC) insertion using a soft J-tipped guide wire which is considered safe and rarely implicated with cardiac tamponade. A bedside transthoracic echocardiogram (TTE) revealed a pericardial effusion with tamponade. An emergent bedside pericardiocentesis was done revealing bloody fluid and resulted in clinical stabilization...

PURPOSE: The ultrasound-guided central venous catheter (CVC) guidewire tip positioning has been demonstrated for catheterization of the right internal jugular vein. We explored the feasibility of an ultrasound-guided right subclavian vein (RScV) CVC tip positioning via a right supraclavicular approach using a microconvex probe. METHODS: Twenty patients scheduled for elective surgery were consecutively included in this observational feasibility study following written informed consent...

Vent vacuum relief valves (VRVs) are used to limit the negative pressure at the ventricular vent catheter tip as well as prevent reversal of blood flow and prevention of air embolism. The purpose of this study was to evaluate the performance of three commercially available ventricular vent valves. The negative pressure at which the vent valve opened was measured at the valve inlet using high-fidelity pressure transducers. Also, the flow rate at which air entrainment occurred due to valve opening was recorded...

Reconstructing the phylogenetic relationships that unite all lineages (the tree of life) is a grand challenge. The paucity of homologous character data across disparately related lineages currently renders direct phylogenetic inference untenable. To reconstruct a comprehensive tree of life, we therefore synthesized published phylogenies, together with taxonomic classifications for taxa never incorporated into a phylogeny. We present a draft tree containing 2.3 million tips-the Open Tree of Life. Realization of this tree required the assembly of two additional community resources: (i) a comprehensive global reference taxonomy and (ii) a database of published phylogenetic trees mapped to this taxonomy...

AIM: To examine the number and nature of investigations performed for suspected pulmonary embolism (PE) in a large teaching hospital and the change in incidence and severity of PE over a decade. MATERIALS AND METHODS: In this retrospective study, all patients investigated for suspected PE using computed tomography pulmonary angiography (CTPA) or lung scintigraphy during 10 years to March 2012 were identified and their records reviewed. In the final year, all reportedly positive CTPA cases were reviewed and PE severity calculated, for comparison with similar historical data...

In this paper, we present a tendon-driven continuum robot for endoscopic surgery. The robot has two sections for articulation actuated by tendon wires. By actuating the two sections independently, the robot can generate a variety of tip positions while maintaining the tip direction. This feature offers more flexibility in positioning the tip for large viewing angles of up to 180 degrees than does a conventional endoscope. To accurately estimate the tip position at large viewing angles, we employed kinematic mapping with a tension propagation model including friction between the tendon wires and the robot body...

OBJECTIVE: To develop an assay for vaginal CA125 and determine if vaginal levels correlate with the phase of the menstrual cycle. STUDY DESIGN: Fifteen women through a total of 20 ovulatory cycles obtained daily vaginal swabs for assay. Sampling began within the first 3 days after menses in and continued into the luteal phase. The subjects eluted the cotton swab tips in vials containing a standard volume of water. At the completion of each cycle the vial concentrations of CA125 were measured with the Siemens IMMULITE 2000...

IMPORTANCE: Imparting surgical change to the nasal tip remains one of the most challenging aspects of rhinoplasty. The surgeon must assess the tip preoperatively and execute the necessary maneuvers to impart the desired change. OBJECTIVE: To assess nasal tip resistance to compression in a cadaveric model before and after specific rhinoplasty maneuvers using a novel method. DESIGN, SETTING, AND MATERIALS: Open rhinoplasty maneuvers were performed at an academic tertiary care center on 6 fresh-thawed cadaver heads...

PURPOSE: Targeted muscle reinnervation (TMR) offers enhanced prosthetic use by harnessing additional neural control from unused nerves in the amputated limb. The purpose of this study was to document the location and number of motor end plates to each muscle commonly used in TMR in the brachium relative to proximally based bony landmarks. METHODS: We dissected 18 matched upper limbs (9 fresh-frozen cadavers). The locations of each of the nerves' muscular insertions into the medial biceps and brachialis were measured relative to the anterolateral tip of the acromion...

This study investigated the effect of the emotional nature of to-be-retrieved material on semantic retrieval monitoring. Across 2 groups, participants were either asked whether they have experienced a tip-of-the-tongue (TOT) state or to make a feeling-of-knowing (FOK) judgment. We examined the overall reporting rate as well as subjective (not accompanied by partial information recall) TOT and FOK reporting, comparing whether these differed between emotional (negatively valenced and arousing) and neutral items...

Globally, enterotoxigenic Escherichia coli (ETEC) is a leading cause of childhood and travelers' diarrhea, for which an effective vaccine is needed. Prevalent intestinal colonization factors (CFs) such as CFA/I fimbriae and heat-labile enterotoxin (LT) are important virulence factors and protective antigens. We tested the hypothesis that donor strand-complemented CfaE (dscCfaE), a stabilized form of the CFA/I fimbrial tip adhesin, is a protective antigen, using a lethal neonatal mouse ETEC challenge model and passive dam vaccination...
