Testing and isolation remain a key component of public health responses to both persistent and emerging infectious *** the value of these measures have been demonstrated in combating recent outbreaks including the COVID-19 pandemic and monkeypox,their impact depends critically on the timelines of testing and start of isolation during the course of *** investigate this impact,we developed a delay differential model and incorporated age-since-symptom-onset as a parameter for delay in *** then used the model to compare the outcomes of reverse-transcription polymerase chain reaction(RT-PCR)and rapid antigen(RA)testing methods when isolation starts either at the time of testing or at the time of test *** the model with estimates of SARS-CoV-2 infection and diagnostic sensitivity of the tests,we found that the reduction of disease transmission using the RA test can be comparable to that achieved by applying the RT-PCR *** constraints and inevitable delays associated with sample collection and laboratory assays in RT-PCR testing post symptom onset,self-administered RA tests with short turnaround times present a viable alternative for timely isolation of infectious cases.

Molecular Structure of Feeds in Relation to Nutrient Utilization and Availability in Animals： A Novel Approach

引用

Engineering 2017年第5期3卷 726-730页

作者： Peiqiang Yu Luciana L. Prates Department of Animal and Poultry Science College of Agriculture and Bioresources University of Saskatchewan Saskatoon SK S7N 5A8 Canada

The invention and development of new research concepts, novel methodologies, and novel bioanalytical techniques are essential in advancing the animal sciences, which include feed and nutrition science. This article introduces a novel approach that shows the potential of advanced synchrotron-based bioanalytical technology for studying the effects of molecular structural changes in feeds induced by various treatments （e.g., genetic modification, gene silencing, heat-related feed processing, biofuel processing） in relation to nutrient digestion and absorption in animals. Advanced techniques based on synchrotron radiation （e.g., synchrotron radiation infrared microspectroscopy （SR-IMS） and synchrotron radiation X-ray techniques） have been developed as a fast, noninvasive, bioanalytical technology that, unlike traditional wet chemistry methods, does not damage or destroy the inherent molecular structure of the feed. The cutting-edge and advanced research tool of synchrotron light （which is a million times brighter than sunlight） can be used to explore the inherent structure of biological tissue at cellular and molecular levels at ultra-high spatial resolutions. In conclusion, the use of recently developed bioanalytical techniques based on synchrotron radiation along with common research techniques is leading to dramatic advances in animal feed and nutritional research.
