Stimulation of palmitate clearance by insulin. Thus, most of the insulin-mediated reduction of plasma NEFA appearance and oxidation can be explained by suppression of intracellular lipolysis during enhanced intravascular triglyceride lipolysis in healthy humans. Our results also suggest that insulin may affect plasma NEFA clearance independently of the suppression of intracellular lipolysis. Keywords: Non-esterified fatty acids, insulin, intracellular lipolysis, lipid oxidation.

JPET #127654 DISCUSSION Animal models in which AF occurs in the setting of underlying cardiac pathology include rapid atrial pacing to induce atrial electrical remodeling Morillo et al, 1995; Gaspo et al, 1997 ; , mitral regurgitation inducing atrial histologic remodeling Everett et al, 2000 ; , acute atrial ischemia Sinno et al, 2003 ; , and rapid ventricular pacing resulting in heart failure. The canine model in which rapid ventricular pacing generally 2-6 weeks duration ; produces ventricular dysfunction leading to atrial remodeling and the ability to sustain AF has been characterized extensively in the literature. Rapid ventricular pacing has been reported to increase atrial dimension Shi et al, 2001 ; , pressure Cha et al, 2004 ; and fibrosis Li et al, 1999; Li et al, 2001; Cha et al, 2004; Hanna et al, 2004 ; . Biochemically, increased atrial AII concentration, increased Bax Bcl-2 ratio, increased expression of phosphorylated MAP kinases, and transiently increased apopotosis have been reported Li et al, 2001; Cardin et al, 2003; Hanna et al, 2004 ; . Increased heterogeneity of conduction and areas of slow conduction in atria, accompanied by decreases in Ito, ICaL and IKs, but no change in IK1, IKur, IKr and ICaT have been reported in electrophysiologic studies Li et al, 1999; Li et al, 2000a; Cha et al, 2004 ; . Both reentrant and focal mechanisms underlying AF have been reported in atrial mapping studies Li et al, 2000b; Derakchan et al, 2001; Ryu et al, 2005; Everett et al, 2006 ; . Pharmacologically, chronic treatment with the ACE inhibitor enalapril attenuated biochemical alterations, reduced fibrosis and decreased the duration of AF in this model Li et al, 2001; Cardin et al, 2003 ; . The acute administration of the IKr blocker dofetilide terminated ongoing AF and prevented the induction of sustained AF in this model Li et al, 2000b.
B. S. Pruett and S. B. Pruett. Cellular BIology & Anatomy, LSU Health Sciences Center, Shreveport, LA. Excessive ethanol EtOH ; consumption is associated with an increased risk of cardiovascular disease, but moderate EtOH consumption is associated with decreased risk of cardiovascular disease. Recent epidemiological and experimental studies indicate that inflammation, particularly the acute phase response, is associated with cardiovascular disease and that moderate EtOH consumption correlates with decreased levels of acute phase proteins in humans. However, the causative relationships and detailed mechanisms involved in these associations are not known, in part because of the lack of an effective animal model. In the present study, mice were given EtOH 32% in water ; by gavage, and the acute phase proteins serum amyloid A SAA ; and serum amyloid P SAP ; were measured by ELISA. In B6C3F1 mice, a high dosage of EtOH 6 g kg ; increased blood levels of SAA and SAP, with maximum values observed 24 hr after dosing. In contrast, a lower dosage 3 g kg ; did not significantly increase the concentration of acute phase proteins. We hypothesized that a high dosage of EtOH acts by decreasing gastrointestinal barrier function and increasing the translocation of bacteria and endotoxin into the blood. Administration of EtOH at 6 g C3H HeJ mice TLR4 mutant, endotoxin hyporesponsive ; was not associated with an increase in SAA concentration at 24 hr, whereas the same treatment of C3H HeOuJ mice TLR4 wild type ; did cause a significant increase in SAA at 24 hr. This supports the hypothesis. The ability of moderate EtOH dosages to inhibit an acute phase response was demonstrated by inhibition of IL-6, SAA, and SAP production induced by exogenous LPS 25 g mouse, iv ; at 3 hr after LPS administration. EtOH at dosages of 3-5 g kg inhibited these responses. Therefore, the mouse model described here exhibits similar suppression of the acute phase response associated with moderate drinking and exacerbation of the acute phase response associated with heavy drinking in humans.

Patents are often used in studies of national innovativeness in different fields. Since a patent is necessary for an invention to be protected, it is a good indicator of innovativeness. We have chosen to study the amount of patenting in the US patent system since the biotechnology, medical technology and pharmaceutical market is global and most of these inventions need to be protected on the large US market. The international comparison of Swedish patenting volumes is based on inventor fractions i.e. if one inventor of four is Swedish, this counts as 0.25 Swedish patents ; of issued patents in the US-patent system6. The national patent analysis included, all in all, 18 750 patents issued during 1986-2001 and having a Swedish assignee and or inventor. The patents in the USPTO server7 were downloaded as screen dumps, i.e. text versions of the front pages of issued patents were retrieved. These front pages were then converted into field-delimited records. A selection of IPC classification codes comprising patents in the following fields was selected: Biotechnology8, Medical Equipment9, Medical Electronics10, and Pharmaceutical and dolasetron.

The Table summarizes the dose-dependent changes in ARI in the control acute AVB group and the chronic AVB group with cardiac hypertrophy. Because of the varying extension of M cells toward the epicardial and endocardial surfaces in the LV free wall and interventricular septum and our finding that maximum transmural dispersion of ARI seemed to occur between epicardial and midmyocardial endocardial sites, we grouped ARIs of sites No. 7 and 8 as Epi and sites No. 1 through 6 as End Mid. The difference between the shortest and longest ARI across each needle was calculated as transmural dispersion of repolarization TDR ; . All data were obtained during pacing at a CL 1000 ms. The Table shows that at baseline both ARIs and TDR were longer in the chronic AV block group compared with control P 0.05 ; . In the control group, dofetilide resulted in dose-dependent moderate prolongation of ARIs 7% at 3 g kg, 18% at 10 g kg, and 20% at 30 g kg ; TDR showed no increase at 3 g kg, increased slightly from 18.5 to 25 ms kg, and showed no additional increase at 30 g kg. On the other hand, in the chronic AV block group, dofetilide resulted in greater dose-dependent increase of ARI 17% at 3 g kg, 24% at 10 g kg, and 31% at 30 g kg ; Similarly, the TDR showed significant dose-dependent increases 20% at 3 g kg, 37% at 10 g kg, and 75% at 30 g kg ; The differences between the dose-dependent effects of dofetilide in the control and dovonex.

E. DOFETILIDE. Several large-scale, double-blind, randomized studies support the efficacy of dofetilide for prevention of AF or atrial flutter 261, 334 ; . To reduce the risks of proarrhythmia, dofetilide should be initiated in the hospital at a dose titrated to renal function and the QT interval. This provides a measure of safety in the event of early proarrhythmic toxicity. Combined results from 966 patients in the SAFIRE-D Symptomatic Atrial Fibrillation Investigative Research on Dofetilide ; and EMERALD studies found dofetilide treatment to be associated with conversion to sinus rhythm, and this effect was dose related: 6%, 10%, and 30% of patients responded within 72 h to 125, 250, and 500 mcg twice a day, respectively 261, 334 ; . Most 87% ; conversions occurred within 30 h after treatment was initiated. The incidence of torsade de pointes was 0.8%. Four of 5 of these incidents occurred in the first 3 days. In SAFIRE-D, dofetilide was associated with 40%, 52%, and 66% of patients in sinus rhythm at 6 months in the 125-, 250-, and 500-mcg-daily dosage groups, respectively, compared with 21% with placebo 261 ; . In EMERALD, suppression of recurrence of AF by dofetilide was also dose dependent: 51%, 57%, and 71% of patients were in sinus rhythm with 125, 250, and 500 mg daily, respectively, compared with approximately 25% with placebo and 60% with sotalol 334 ; . F. FLECAINIDE. Two placebo-controlled studies 311, 335 ; found flecainide to be effective in postponing the first recurrence of AF and the overall time spent in AF; and other randomized studies 336, 337 ; found its efficacy to be comparable to that of quinidine, with fewer side effects. Efficacy is further supported by uncontrolled studies 312, 338 ; . Van Gelder et al. 339 ; showed that time to recurrence of AF was significantly longer with flecainide than without treatment, and severe ventricular proarrhythmia or sudden death was not observed with a mean dose of 199 mg daily. Side effects occurred in 5 patients 9% ; and were predominantly related to negative dromotropism, with or without syncope. Compared with long-acting quinidine 1, 100 mg daily ; , flecainide 200 mg daily ; was superior in preventing recurrent AF after cardioversion and was associated with and dronabinol.

KIJTAWORNRAT ET AL. Experimental protocol. Animals were anesthetized with a combination of ketamine and xylazine 35 and 5 mg kg im ; . The right marginal ear vein was cannulated for intravenous administration of drug. Rabbits were placed in dorsal recumbency. The right and left thoracic limb electrodes were attached to the right and left hemithoraces, the electrocardiograph was switched to limb lead I, and a bipolar transthoracic ECG was obtained on a Biopac MP100 Data Acquisition Unit Biopac Systems, Inc., Santa Barbara, CA ; . The high-pass filter was set at 0.01 Hz and the low-pass filter at 1 kHz, and signals were digitally sampled at a frequency of 2 kHz. Anesthesia was maintained as necessary by administration of further doses of ketamine and xylazine 20 and 3 mg kg im, respectively ; . All rabbits were allowed at least 10 min stabilization before starting any drug infusion. Drugs were selected because they are either known torsadogens or known not to produce TdP. Torsadogens were selected from groups possessing varied pharmacological properties e.g., class IA, class III, prokinetic ; . All drugs were infused intravenously over a period of 10 min, with a 20-min interval between doses. The infusion was stopped as soon as TdP started. The drugs tested in this study were amiodarone 3, 10, and 30 mg kg; control group n 6, myocardial failure group n 4 ; , cisapride 0.1, 0.25, 0.50 mg kg; control group n 4, myocardial failure group n 4 ; , clofilium 0.1, 0.2, 0.4 mg kg; control group n 6, myocardial failure group n 5 ; , dofetilide 0.005, 0.01, 0.02, and 0.04 mg kg; control group n 10, myocardial failure group n 7 ; , quinidine 3, 10, and 30 mg kg; control group n 6, myocardial failure group n 4 ; , and verapamil 0.25, 0.50, and 1.0 mg kg; control group n 6, myocardial failure group n 4 ; . The doses of each drug were chosen according to those used in previously published rabbit studies by other research groups Batey and Coker, 2002; Carlsson et al., 1997; Farkas et al., 2002; Lu et al., 2000 ; . RR and QT intervals were measured 15 min after each drug dose had been infused. The QT interval was corrected for heart rate by dividing the QT interval by the cube root of the preceding RR interval Fridericia, 1920 ; . Measurements were made from at least 12 consecutive cardiac cycles, and the average was used. The ECG intervals were measured in beats that originated from the sinoatrial node; however, at some points ECG intervals could not be obtained from all animals because of marked arrhythmia. The QT interval was defined as the time between the first deviation from the isoelectric line during the PR interval until the end of the T wave. TdP was defined as a polymorphic ventricular tachycardia where clear twisting of the QRS complexes around the isoelectric axis was seen. Drugs. Amiodarone hydrochloride Sicor Pharmaceuticals, Irvine, CA ; was prepared by diluting commercial amiodarone for injection 450 mg amiodarone in 9 ml diluent ; with 9 ml of 0.9% NaCl to a final concentration of 25 mg ml. Cisapride Medisca Inc., Plattsburgh, NY ; was dissolved in 10% acetic acid to form a stock concentration of 10 mg ml. Clofilium tosylate Sigma, St Louis, MO ; was dissolved in 0.9% NaCl solution to form a stock concentration of 3 mg ml. Dofetilide Pfizer, Groton, CT ; was dissolved in 0.9% NaCl with the help of 0.1M hydrochloric acid to form a stock concentration of 0.1 mg ml. Quinidine hydrochloride Sigma ; stock concentration of 30 mg ml ; and verapamil hydrochloride Sigma ; stock concentration of 2 mg ml ; were also dissolved in 0.9% NaCl. Analyses of dosing solutions were not performed; however, each drug was injected within 60 min of preparation. Statistics. Values are expressed as mean SEM. Fisher's exact tests were used to compare the incidence of TdP between groups. A probability value of p 0.05 was considered to be significant.

In Boise, Idaho, a mother cat recently gave birth to a litter of kittens and was overly-aggressive in licking their faces. Bacteria were transferred into the kittens' still-closed eyes, causing a bilateral endopthalmitis in two of the kittens. To save their lives, both had to have their eyes removed and the eyelids sewn shut. The two blind kittens recovered well. They were always kept together since they seemed to need one another and would become frenzied if separated. As they matured, they were both outgoing and friendly as long as they remained with each other. When placed in a room, the two little kittens would and dok.
Data were analyzed by ANOVA with SPSS for Windows version 10, SPSS Inc ; . Continuous variables are expressed as mean SD or median and range, and comparative univariate analyses were performed with the t test, Mann-Whitney U test, or Wilcoxon signedrank test, as appropriate. Binomial or ordinal data are expressed as percentages, and comparative univariate analyses were performed with the 2 test, 2-sided Fisher exact test, or binomial logistic regression, as appropriate. A probability value P 0.05 was taken to represent a statistically significant difference between groups. The effect of preoperative, operative, and postoperative variables on outcome was tested by univariate and multivariate analyses. Univariate analyses of early-outcome measures were made with the 2 test, 2-sided Fisher exact test, and binomial logistic regression. Variables with P 0.1 were included in a stepwise logistic regression model. Results of these multivariate analyses have been expressed as odds ratios ORs ; with 95% CIs for variables with P 0.05 and dulcolax.
