Relationship Between Rr And Qt Intervals In Normal And Pacing-Induced Heart Failure Dogs, Vudhiporn Limprasutr, Nakkawee Saengklub, Suwanakiet Sawangkoon, Chollada Buranakarl, Narongsak Chaiyabutr, Anusak Kijtawornrat

The Thai Journal of Veterinary Medicine

This study was conducted to determine the effects of rapid ventricular pacing on cardiac function and hemodynamics, and to determine the most suitable QTc formula for the effects of alterations in the RR interval on the QT interval of conscious dog with heart failure (HF). Electrocardiograms were acquired from dogs (n=18) at baseline and after rapid ventricular pacing (6, 9, 12 weeks). RR and QT intervals were measured and QTc intervals were calculated using 3 common formulae (Bazett, Fridericia and Van de Water). HF was confirmed by reduced left ventricular fractional shortening (p<0.05), significantly faster heart rate (p<0.001) and significantly changed QT and QTc intervals (p<0.001) when compared to the baseline. This model also demonstrated decreased systolic arterial pressure (p<0.01) and increased BNP (p<0.05). The appropriate regression equations were QT = 152.4+0.08RR for normal dogs and QT = 32.3 (RR) 0.29 for HF dogs. In normal dogs, the Van de Water formula reveals the least dependency of QTc on RR interval. In HF dogs, the Fridericia formula appears to be the best equation to remove the influence of heart rate.

Temperature, Hypoxia, And Mycobacteriosis: Effects On Adult Striped Bass Morone Saxatilis Metabolic Performance, Dominique Lapointe, Wolfgang K. Vogelbein, Mary C. Fabrizio, David T. Gauthier, Richard W. Brill

Biological Sciences Faculty Publications

Mycobacteriosis, a chronic bacterial disease of fishes, is prevalent in adult striped bass from Chesapeake Bay (USA). Although environmental factors may play a role in disease expression, the interaction between the disease and environmental stress remains unexplored. We therefore examined the individual and interactive effects of elevated temperature, hypoxia, and mycobacteriosis on the metabolism of wild-caught adult striped bass from Chesapeake Bay using respirometry. Because the spleen is the primary target organ of mycobacteriosis in striped bass, we hypothesized that the disease interferes with the ability of fish to increase their hemato crit in the face of increasing oxygen demands. …

Effect Of Confinement On Water-Borne And Whole Body Cortisol In Wild And Captive-Eared Rainbowfish (Melanoteania Duboulayi), Amina Zuberi, Culum Brown, Sinan Ali

Physiology Collection

Whole body and water-borne cortisol levels were measured in captive reared and wild Rainbowfish (Melanoteania duboulayi Castelnau 1878) subjected to social isolation by confining them in a beaker for 30 min to induce an acute stress response. Wild fish had higher levels of cortisol before and after exposure to a mild stressor and also showed the greatest stress response. The differences in stress responses are likely the result of artificial selection in the captive environment. Importantly, there was a strong linear relationship between whole body and water-borne cortisol in wild and captive reared populations (r2 =0. 95 and 0.84, …

Nebraska Beef Cattle Reports

Granulosa cell expression of VEGFAisoforms in dominant bovine follicles was evaluated. Collection of granulosa cells via follicle aspiration revealed altered expression of the proangiogenic VEGFA_164 isoform but not the antiangiogenic VEGFA_164B isoform prior to and after the LH surge. Expression of VEGFA_164 declines as both the LH surge and ovulation approaches. In addition, VEGFA_164 and VEGFA_164B expression prior to the LH surge was positively correlated with FSHR and CYP19A1 expression, suggesting that VEGFA expression may be regulated by FSH. These data indicate differential expression of VEGFA isoforms may be an important feature of bovine dominant follicle development.
