Fishing, reproductive volume and regulation: population dynamics and exploitation of the eastern Baltic cod
The relative importance of exploitation rate and environmental variability in generating fluctuations of harvested populations is a key issue in academic ecology as well as population management. We studied how the eastern Baltic cod (Gadus morhua) is affected by fishing and environmental variation by using a newly developed single species state-space model. Survey data and auxiliary environmental
Effect of UGT2B7-900G > A (-842G > A; rs7438135) on morphine glucuronidation in preterm newborns: results from a pilot cohort
Aim: Assess association between UGT2B7 polymorphism -900G>A (rs7438135, also known as -842G>A) with morphine kinetics in preterm newborns undergoing mechanical ventilation. Materials & methods: Thirty-four infants were enrolled in a randomized clinical trial and allocated to rapid sequence intubation with remifentanil (1 mu g/kg) or morphine (0.3 mg/kg). The latter group was included in our st
Assessment of myocardium at risk with contrast enhanced steady-state free precession cine cardiovascular magnetic resonance compared to single-photon emission computed tomography
Background: Final infarct size following coronary occlusion is determined by the duration of ischemia, the size of myocardium at risk (MaR) and reperfusion injury. The reference method for determining MaR, single-photon emission computed tomography (SPECT) before reperfusion, is impractical in an acute setting. The aim of the present study was to evaluate whether MaR can be determined from the con
Ligand induced galectin-3 self-association.
Many functions of galectin-3 entail binding of its carbohydrate recognition site to glycans of a glycoprotein, resulting in cross-linking thought to be mediated by its N-terminal non-carbohydrate-binding domain. Here we studied interaction of galectin-3 with the model glycoprotein asialofetuin (ASF), using a fluorescence anisotropy (FA) assay to measure the concentration of free galectin carbohydr
Realistic Instrumentation Platform for Active and Passive Optical Remote Sensing.
We describe the development of a novel versatile optical platform for active and passive remote sensing of environmental parameters. Applications include assessment of vegetation status and water quality. The system is also adapted for ecological studies, such as identification of flying insects including agricultural pests. The system is based on two mid-size amateur astronomy telescopes, continu
Resolution and Determination of the Absolute Configuration of a Twisted Bis-Lactam Analogue of Tröger's Base: A Comparative Spectroscopic and Computational Study.
The first reported twisted bis-lactam, a racemic Tröger's base (TB) analogue (2), was resolved into its enantiomers on a chiral stationary phase HPLC column. The absolute configuration of (+)-2 was determined to be (R,R)-2 by comparing experimental and calculated vibrational circular dichroism (VCD) and electronic circular dichroism (ECD) spectra. The absolute configuration of (-)-2 was determined
Neurologic Outcomes and Postresuscitation Care of Patients With Myoclonus Following Cardiac Arrest.
To evaluate the outcomes of cardiac arrest survivors with myoclonus receiving modern postresuscitation care.
Health correlates of Workplace Bullying: A 3-wave prospective follow-up study
A combined study of the equation of state of monazite-type lanthanum orthovanadate using in situ high-pressure diffraction and ab initio calculations.
Lanthanum orthovanadate (LaVO4) is the only stable monazite-type rare-earth orthovanadate. In the present paper the equation of state of LaVO4 is studied using in situ high-pressure powder diffraction at room temperature, and ab initio calculations within the framework of the density functional theory. The parameters of a second-order Birch-Murnaghan equation of state, i.e. those fitted to the exp
A model for habitat selection and species distribution derived from central place foraging theory.
We have developed a habitat selection model based on central place foraging theory. An individual's decision to include a patch in its habitat depends on the marginal fitness contribution of that patch, which is characterized by its quality and distance to the central place. The essence of the model we have developed is a fitness isocline which is a function of patch quality and travel time to the
Detection of Soot Using a Resistivity Sensor Device Employing Thermophoretic Particle Deposition
Results are reported for thermophoretic deposition of soot particles on resistivity sensors as a monitoring technique for diesel exhaust particles with the potential of improved detection limit and sensitivity. Soot with similar characteristics as from diesel exhausts was generated by a propane flame and diluted in stages. The soot in a gas flow at 240–270C∘ was collected on an interdigitated elec
A Compensation Technique for Two-Stage Differential OTAs
In this paper a frequency compensation method for operational transconductance amplifiers is proposed, which poses no power overhead compared to Miller compensation, while improving the 3dB bandwidth, the unity gain frequency and the slew rate. The technique employees positive feedback to introduce an extra left half plane zero to cancel a pole.The phase margin shows good robustness against proces
A Six-Year Exercise Program Improves Skeletal Traits without Affecting Fracture Risk - a Prospective Controlled Study in 2621 Children.
Most pediatric exercise intervention studies, that evaluates the effect on skeletal traits include volunteers and follow bone mass for less than three years. We present a population-based six-year controlled exercise intervention study in children with also bone structure and incident fractures as endpoints. Fractures were registered in 417 girls and 500 boys in the intervention group (3969 person
Effects of solid retention time on anaerobic digestion of dewatered-sewage sludge in mesophilic and thermophilic conditions
Anaerobic digestion of dewatered-sewage sludge using continuous stirred tank reactors (CSTRs) in duplicates was evaluated under thermophilic (50 degrees C) and mesophilic (37 degrees C) conditions over a range of nine solid retention times (SRTs). The 35- and 30-day SRTs were designed to simulate a full-scale plant operation while 25-, 20-, 15- and 12-day SRTs were planned to evaluate process perf

Processing of Multi-dimensional Sensorimotor Information in the Spinal and Cerebellar Neuronal Circuitry: A New Hypothesis.
Why are sensory signals and motor command signals combined in the neurons of origin of the spinocerebellar pathways and why are the granule cells that receive this input thresholded with respect to their spike output? In this paper, we synthesize a number of findings into a new hypothesis for how the spinocerebellar systems and the cerebellar cortex can interact to support coordination of our mult
Non-obstructive azoospermia and clinical varicocele: therapeutic options.
Ten to fifteen percent of infertile men are azoospermic, and sixty percent of these men have been classified as having non-obstructive azoospermia (NOA). NOA results from testicular failure, and one of the causes of this is the presence of varicocele. Varicocele is observed in 5-10 % of men with NOA. This review discusses the impact of varicocele repair on semen quality and pregnancy rate among me
Against the Grain: "Matter" and "Spirit"
Isolation of microbial natural products.
In principle, the isolation of secondary metabolites from microbes does not differ from their isolation from other organisms. The extraction procedure may of course be quite different, especially if it is carried out in an industrial scale, but when an extract containing the metabolites of interest is at hand, it is the same palette of adsorbents and chromatographic techniques that provide the maj
