Article Synopsis
  • * A significant challenge in this testing method is the interference caused by surface conditions, including both random factors (like contamination) and permanent factors (like surface roughness).
  • * The research conducted evaluated how different levels of surface roughness (ranging from 0.28 to 219 µm) impacted the propagation of ultrasonic waves, revealing that roughness notably affects wave attenuation and transit time, with differences over 15 dB in signal amplification and more than 50 µs in transition time.

Background: Infectious bursal disease (IBD) is a highly infectious disease of chicken found in all latitudes, due to the very high resistance to environmental conditions and commonly used disinfectants of the IBD virus (IBDV).

Methods: This study was conducted to evaluate three IBD vaccination protocols in broiler chicken in terms of their effectiveness (clinical observations and production performance of the flock), estimation of serological baseline values (with the use of two different commercial ELISA kits) and the degree of progression of BF lesions (histopathological lesion score (HLS)) after vaccination. The three protocols were (I) single vaccination using an intermediate plus vaccine, (II) double vaccination with an intermediate vaccine and (III) double vaccination with an intermediate plus vaccine.

Article Synopsis
  • Over the past 50 years, more invasive cardiovascular procedures have been performed worldwide, increasing risks of acute brain injury during and after these interventions.
  • Current international guidelines often overlook the issue of acute brain injury from cardiovascular procedures, which can lead to worse medical outcomes and higher healthcare costs.
  • The international Consensus Statement aims to provide recommendations for prevention, diagnosis, and treatment of this acute brain injury while also highlighting areas where more research is needed.
