BACKGROUND Vector-borne plant disease management can be enhanced by deployment of antifeedants in addition to the use of broad-spectrum neurotoxic insecticides. The effects of pymetrozine on Asian citrus psyllid (ACP), Diaphorina citri Kuwayama, feeding behaviour, survival and transmission of Candidatus Liberibacter asiaticus (Las), the presumed causal pathogen of huanglongbing, were investigat...

We report here the draft genome sequence of "Candidatus Liberibacter asiaticus" strain HHCA, collected from a lemon tree in California. The HHCA strain has a genome size of 1,150,620 bp, 36.5% G+C content, 1,119 predicted open reading frames, and 51 RNA genes.

We tested the assumption that nifedipine blocks L-type calcium current [I(Ca(L))] at +10 mV and unmasks Na(+)/Ca(2+) exchange-triggered contractions in guinea pig isolated ventricular myocytes. Voltage-clamp pulses elicited I(Ca(L)) at +10 mV and evoked contractions in myocytes superfused with Tyrode's solution (35 degrees C). Nifedipine blocked I(Ca(L)) with an IC(50) of 0.3 microM; this decre...

This study presents the effects of exogenous melatonin application at different concentrations (50, 100, and 200 ?M) on morphological, physiological, antioxidant defense systems buttercup plant under salinity stress (4.5 5.5 dS·m?1 EC). Expectedly, negatively affected growth parameters, cell membrane stability, POX enzyme activity R. asiaticus compared to non-stressed plants. However, in a dose...

The characteristics of nickel (Ni) block of L-type Ca current (I(Ca, L)) were studied in whole cell patch-clamped guinea pig cardiac myocytes at 37 degrees C in the absence and presence of 100 microM cAMP in the pipette solution. Ni block of peak I(Ca,L) had a dissociation constant (K(d)) of 0.33 +/- 0.03 mM in the absence of cAMP, whereas in the presence of cAMP, the K(d) was 0.53 +/- 0.05 mM ...

AIMS Our goal was to determine the relative contributions of demographic variables, drugs, comorbidities, and weather conditions on serum calcium (Ca) and phosphate (Pi) in patients admitted to a tertiary referral center. METHODS For 12,667 consecutive patients admitted to the Kantonsspital St. Gallen, drug history on admission, age, sex, body weight, ICD-10 diagnoses, and laboratory data wer...

Objective: The L-type calcium current (I ) in isolated human atrial myocytes was investigated as a possible target of insulin in the Ca,L regulation of cardiac function. Methods: Atrial myocytes were obtained from patients undergoing cardiac surgery. Using the whole-cell configuration of the patch-clamp technique, we investigated the stimulation of I by insulin in single human atrial myocytes. ...
