Although leaf chloroplast transformation technology was developed more than a decade ago, no reports exist of stable transformation of undeveloped plastids or other specialized plastid types, such as proplastids, etioplasts, or amyloplasts. In this work we report development of a dark-grown tobacco suspension cell model system to investigate the transformation potential of undeveloped plastids. Electron microscope analysis confirmed that the suspension cells carry plastids that are significantly smaller approximately 50-fold less in volume ; and have a very different subcellular localization and developmental state than leaf cell chloroplasts. Using antibiotic selection in the light, we demonstrated that both plastid and nuclear transformation of these cell suspensions is efficient and reproducible, with plastid transformation frequency at least equal to that of leaf chloroplast transformation. Homoplasmic plastid transformants are readily obtained in cell colonies, or in regenerated plants, providing a more consistent and versatile model than the leaf transformation system. Because of the uniformity of the cell suspension model, we could further show that growth rate, selection scheme, particle size, and DNA amount influence the frequency of transformation. Our results indicate that the rate-limiting steps for nuclear and plastid transformation are different, and each must be optimized separately. The suspension cell system will be useful as a model for understanding transformation in those plant species that utilize dark-grown embryogenic cultures and for characterizing the steps that lead to homoplasmic plastid transformation.

Site establishment in the gut occurs in the first week after trypanosome uptake, during which time infected flies show increasing expression of both attacin and defensin genes Fig. 4 ; . By day 10, it is possible to determine microscopically which flies have established an infection and which have cleared the parasite. At 10 days, the expression of attacin, defensin, and diptericin was found to be high in infected and noninfected flies Fig. 4 A ; , but by 20 days, significantly less attacin and defensin transcript and, to a lesser extent, diptericin transcript was detected in flies that had eliminated parasite infections Fig. 4B ; .

In Figure 7 and Table 1, the effects of flecainide on AF are given. Flecainide prolonged AFCL by 48%, whereas RPAF did not change significantly. Thus, the excitable period increased from 23 5 to 189%; P 0.01 ; . The windows of stable and unstable entrainment increased from 9 5 to and from 27 8 to ms, respectively P 0.05 ; . Because RPAF did not change and CVAF was depressed by 44%, flecainide shortened the atrial wavelength during AF by 41% P 0.05 and flexeril.

Have minimal ECG changes at baseline but would respond to flecainide with a prominent ST segment elevation and electrical instability. Once again this is in agreement with the clinical findings showing a "coved-type" ST segment elevation only after flecainide administration Fig. 1 ; . Yan and Antzelevitch 50 ; suggested that the strong ITO current of epicardial cells in the presence of a reduced inward current is responsible for the loss of AP dome. Coherently with this hypothesis we observed prompt AP morphology normalization when ITO was decreased by 50%. At variance with flecainide, mexiletine induced only a slight APD reduction with no loss of the AP dome. This is in agreement with clinical observations by Shimizu et al. 42 ; , who showed that mexiletine did not elicit ST segment elevation in BrS patients. As of today, a conclusive explanation of the differential effect of flecainide and mexiletine in the BrS patients is not available. Our data suggest that flecainide, but not mexiletine, unmasked BrS silent mutation mainly because of their differential blocking effect on the inward current greater extent the ICa block ; . Thus we suggest that in presence of sodium channel blockers, the balance between ICa and ITO has to be crucially important for unmasking the arrhythmogenic substrate in BrS patients. This hypothesis is in accordance with the experimental findings of Fish and Antzelevitch 14 ; , whose data suggested that combined calcium channel block may be more effective than sodium channel block alone in unmasking the and flucytosine.

Background. The interim results of the Cardiac Arrhythmia Suppression Trial requires physicians to use a higher threshold for employing antiarrhythmic agents in the treatment of benign or potentially lethal ventricular arrhythmias. Many have managed patients by switching to the traditional class I quinidine despite its known proarrhythmic tendency. Methods and Results. To evaluate the relation between quinidine therapy and mortality in patients with benign or potentially lethal ventricular arrhythmias, we performed a metaanalysis on four randomized double-blind active controlled parallel trials evaluating 1, 909 patients in which quinidine n 502 ; was compared to flecainide n 141 ; , mexiletine ni 246 ; , tocainide n 67 ; , and propafenone n 53 ; . All four trials had similar patient selection, protocols, and methodology e.g., placebo lead-in and Holter monitoring ; but varying lengths of drug exposure. A total of 12 deaths were reported on quinidine and four deaths on the other drugs: two on mexiletine, one on flecainide, and one on tocainide. The statistical analysis of the mortality rates was based on techniques for combining data across separate strata. Based on maximum likelihood estimation, the combined risk of dying on quinidine was statistically significantly higher compared to the other four drugs with a risk difference of 1.6%. The 95% confidence interval was 0-3.1% p 0.05 ; . The likelihood ratio test for uniformity of-the risk difference across strata showed the trials to be homogeneous p 0.88 ; . There was one death recorded for the placebo lead-in period 2 weeks' exposure for 624 patients and 1 week for 385 patients ; , and seven deaths were reported within 2 weeks on active drug treatment six on quinidine and one on mexiletine. Furthermore, proarrhythmia was reported in 20 patients on quinidine versus 11 patients on the four other drugs p 0.09 ; . Conclusions. These data suggest that quinidine may have an adverse effect on mortality as compared to other class I antiarrhythmic agents and that individualized patient selection for the use of this agent be carefully weighed relative to its potential for harm and benefit.

Today after a torrid walk through the thick of the city, as a respite from the fumes, the heat, the dust, the glitter I was tempted into a cinema. I liked the look of the poster: Kung-Fu babes, dark glasses, swanky cars. I bought my ticket from a sweet woman in a little glass box where she sat fiddling with a bunch of coloured drinking straws. By the drapes leading into the auditorium stand two ushers, like Tweedledum and Tweedledee, in red jackets, bow ties, each with a Chinese Flying Eagle chromium torch protruding from their breast pocket. I ushered to a seat not difficult because I the only member of the audience ; and then sit in the dark for twenty minutes: no film. No film because the projectionist hasn't turned up from his lunch. The lady in the booth smiles sweetly, giggles at the little packet of washing powder I happen to be carrying and shows me the intricate flower she has built from her drinking straws.

Is polymorphic leading to a diminished capacity to clear specific drugs in genetically affected individuals. For P450 2C9 substrates, such as warfarin or phenytoin, that have low therapeutic margins of safety, diminished metabolic capacity due to genetic polymorphisms or drug-drug interactions can lead to toxicity at normal therapeutic doses 1 ; . P450 2C9 has also been implicated in the synthesis of arachidonic acid epoxides in extrahepatic tissues where they regulate blood pressure 2 ; . Like other P450 subfamilies, the 2C enzymes share roughly 70% or greater amino acid identity. However, the 2C genes have duplicated and diverged rapidly as mammalian species evolved leading to different numbers of enzymes in various species and highly divergent substrate selectivities. This diversity reflects high rates of non-synonymous substitutions that often alter residues that line the active site cavity and determine substrate selectivity. Human P450s 2C9 and 2C19 are closely related with roughly 91% amino acid identity. Although they exhibit distinct substrate selectivities, residues predicted to line the active site cavity, based on the published structures of other mammalian P450s 3-6 ; , do not differ between the two enzymes. This suggests that conformation changes are likely to underlie differences in the substrate selectivities of P450s 2C9 and 2C19 and that the structure s ; of one or both will differ from those previously published. This is supported by studies of chimeric enzymes generated from P450s 2C9 and 2C19 that have generally identified amino acid residues that are predicted to reside outside the substrate-binding cavity as determinants of their distinct catalytic properties 7-9 and flecainide.

Overall proportion of agreement was 88% with a Kappa score of 0.59. Hence, all the subjects with the "Brugada sign" in our population had a saddleback-type ECG abnormality. The mean age of the subjects with the "Brugada sign" was 20 3 years. In the second study population of 542 subjects, both investigators found three subjects 0.55%, CI: 0.071.18% ; two males and one female ; with a Brugada-type ECG pattern Fig. 2 b . These three cases were unanimously interpreted by both investigators 100% agreement ; . All Finnish electrophysiologists and cardiologists replied to our electronic survey. None of them had diagnosed Brugada syndrome. A flecainide test or some other pharmacological test to reveal a latent Brugada syndrome had been performed in 20 cases. The tests were negative in all cases. Thus, there appear to be no clinically documented cases of Brugada syndrome in Finland.

Use with NRT One study has suggested that combined nicotine patch therapy and bupropion may produce higher quit rates than nicotine patches alone. Combination therapy may therefore be recommended to patients attending specialist cessation clinics who find it difficult to quit using a single pharmacotherapy. Monitoring for hypertension is recommended when combined therapy is used. Special groups Chronic obstructive pulmonary disease--Smoking cessation is the most important intervention in this disease. Bupropion has been shown to be effective and well tolerated in this group of patients. Ischaemic heart disease--Smoking cessation is one of the most important interventions in this disease. Bupropion is not contraindicated or subject to caution except in diabetic patients treated with hypoglycaemic agents or insulin caution ; or in patients taking propafenone or flecainide dose reduction of antiarrhythmics advised.
