Organization of the IBV Genome
1984We have investigated how the information contained within the large RNA genome of IBV is expressed. We began by examining the structure of IBV-specified RNAs. Infected chicken embryo kidney (CEK) cells contain at least 6 IBV RNA species. These consist of the viral genome, RNA F, with an estimated complexity of 23 kb1, and subgenomic RNAs A, B, C, D ...

Avian Diseases, 2005
Vaccination against infectious bronchitis (IB) is aimed to protect against clinical IB. The question is, however, whether vaccinated birds are also protected against predisposure for colibacillosis after a subsequent IBV infection. We examined this research question in four experiments.

Vaccine, 2017
IBV genotype QX causes sufficient disease in Europe for several commercial companies to have started developing live attenuated vaccines. Here, one of those vaccines (L1148) was fully consensus sequenced alongside its progenitor field strain (1148-A) to determine vaccine markers, thereby enabling detection on farms.

Structural Characterization of IBV Glycoproteins
1984Avian infectious bronchitis virus (IBV) causes economically important disease in chickens, affecting both respiratory and non-respiratory tissues. Like other coronaviruses IBV virions contain three virus-coded protein structures, the spike (S; surface projection, peplomer), nucleocapsid (N) and matrix (M) proteins1. The polypeptides of M and N proteins

Dynamic IBVS control of an underactuated UAV
2012 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2012In this paper image based visual servo approach for 3D translational motion and yaw rotation of an under-actuated flying robot is considered. Taking into account the complexity of dynamics of flying robots, main objective of this paper is to consider the dynamics of these robots in designing an image based control strategy.

Analysis of Messenger RNA within Virions of IBV
1994The presence of subgenomic mRNAs (sgRNAs) in virions of infectious bronchitis virus was examined by probing Northern blots of RNA extracted from virions using as a probe a cDNA of the 3'-terminal nucleocapsid protein (N) gene. The sgRNAs were readily detected even after extensive purification of virions and after RNase A treatment of virions. The molar

Optimal motion control for IBVS of robot
Proceedings of the 10th World Congress on Intelligent Control and Automation, 2012In conventional image-based visual servoing (IBVS), the robot end-effector (camera) motion is controlled directly according to image error, there isn't direct control over the Cartesian velocities of the robot end-effector. As a result, the robot trajectories can be seemingly roundabout in Cartesian space. This paper presents a new control scheme, that

IBVS with fuzzy sliding mode for robot manipulators
2015 International Workshop on Recent Advances in Sliding Modes (RASM), 2015Closed loop control of robot manipulator's end effector pose with visual feedback is called as visual servoing (VS). As one of the approaches for VS, image-based visual servoing (IBVS) has the advantage of no pose estimation for commonly used eye-in-hand configured manipulators.

Sequences Required for Replication and Packaging of IBV RNA
2001We have used a naturally occurring IBV defective RNA (D-RNA), CD-91 (9.1 kb; Penzes et al., 1994) to investigate IBV replication and packaging signals. This D-RNA comprised the 5’-most 1133 nucleotides (domain I, including the 528 nucleotide 5’ untranslated region, UTR) and 3’-most 1626 nucleotides (domain III) of the genome and a middle section ...

Treatment of Heterogeneous Emphysema Using the Spiration IBV Valves
Thoracic Surgery Clinics, 2009Ninety-eight emphysema patients were treated at 13 international sites during a 3-year series of single-arm, open-label studies with the IBV valve and a multi-lobar treatment approach. Fifty six percent of subjects had a clinically meaningful improvement in health-related quality of life, but standard pulmonary function and exercise studies were ...
