Abstract Background The Oral Polio Vaccine (OPV or Sabin) is genetically unstable and may mutate to form vaccine-derived polioviruses (VDPVs).Methods In 2014, two VDPVs type 2 were identified during routine surveillance of acute flaccid paralysis (AFP) cases.Consequently, a retrospective Tanks/Jerseys VDPV survey was conducted to ensure that there
Pediatric Clinical Trials in Mainland China Over the Past Decade (From 2009 to 2020)
In mainland China, there remains a shortage of pediatric drugs.The Chinese government has recently launched policies and incentives to encourage pediatric drug development and clinical trials.However, data on the CALENDULA SHAMPOO characteristics or development trends of these trials are limited.In this review, we extracted source data from the Chi
Design of New Submerged Ozone Generator
In order to meet the demand of adjustable ozone concentration and reduce energy consumption, a new submerged ozone generator was designed.The nozzle, reaction SAL SUDS chamber and electrode plate were studied and optimized.The mechanical structure design of the device was completed.The electrical circuit model was built by Matlab/Simulink, the desi
Nucleus accumbens local circuit for cue-dependent aversive learning
Summary: Response to threatening environmental stimuli requires detection and encoding of important environmental features that dictate threat.Aversive events are highly salient, which promotes associative learning about stimuli that signal this threat.The Spreads nucleus accumbens is uniquely positioned to process this salient, aversive informatio
