West Nile virus (Flaviviridae: Flavivirus) is a serious infectious disease that recently spread across the North America continent. A spatial analysis tool was developed on the ArcMap 9.x platform to estimate potential West Nile virus activity using a spatially explicit degree-day model. The model identifies when the virus Extrinsic Incubation Period (EIP) is completed within the vector longevi...

The objective of the present experiment was to quantify the gas production parameters, methane emission and microbial nitrogen production of a conventional total mixed ration including corn silage, alfalfa hay, wheat straw and concentrate (390, 110, 22 and 478 g/kg of diet DM, respectively) treated with different levels of Natuzyme® and pre-incubation time after enzyme administration. Two hundr...

Fifty-four roughages of known voluntary dry-matter intakes (DMI; range 7.8-35.2 g/kg live weight per d) were examined in vitro in a gas production test. Samples (200 mg) of roughage and roughage neutral-detergent fibre (NDF) respectively were incubated in a mixed suspension of rumen contents for 96 h and the gas volumes recorded after 4, 6, 8, 12, 24, 30, 36, 48, 54, 60 and 96 h. The kinetics o...

the effect of inclusion of garlic essential oil (eo) at 33, 66 and 100 μg ml-1, raw garlic (gar) at 5, 10 and 15 mg ml-1 and monensin (mon) at 7.5 μg ml-1 of incubation medium on organic matter digestibility (omd) was studied with in vitro gas production, ankom daisyii and conventional in vitro (ivomd) methods. the material was incubated with sheep ruminal fluid and the experimental design was ...

the effect of three levels of eucalyptus leaf (0, 28.65 or 57.37mg/200mg substrate), which were either oven, freeze or air dried on in vitro ruminal fermentation characteristics was assessed. the studied parameters were in vitro gas production (ivgp), methane production, ammonia (nh3-n) concentration, in vitro organic matter degradability, partitioning factor (pf) (ratio of substrate truly degr...

After an initial period of unsuccessful work at solving a problem, a subject might either continue to work uninterruptedly or put the problem temporarily aside, returning to it later. The elusive laboratory phenomenon called "incubation" refers to superior performance for those subjects who return to the problem after a delay rather than working continuously on the problem. The forgetting-fixat...

Hypoxia is a common component of many developmental insults and has been studied in early-stage chicken development. However, its impact on cardiac function and arterial-ventricular coupling in late-stage chickens is relatively unknown. To test the hypothesis that hypoxic incubation would reduce baseline cardiac function but protect the heart during acute hypoxia in late-stage chickens, white L...

The effect of inclusion of garlic essential oil (EO) at 33, 66 and 100 μg mL-1, raw garlic (GAR) at 5, 10 and 15 mg mL-1 and monensin (MON) at 7.5 μg mL-1 of incubation medium on organic matter digestibility (OMD) was studied with in vitro gas production, ANKOM daisyII and conventional in vitro (IVOMD) methods. The material was incubated with sheep ruminal fluid and the experimental design was ...

Shark cartilage is considered as a natural dietary supplement consisting of anti-angiogenic, immunostimulatory, and anti-inflammatory characteristics. Therefore, this study was designed to inspect the possibility that whitecheek shark (Carcharhinus dussumieri) cartilage proteins motivate expression of NKG2D, CXCR3, NKP46, and NKP44 receptors on natural killer cells and their activities against ...
