With tensions over trade with China escalating, President Donald Trump said on Friday that he is “ordering” the U.S. postal service and express shipping companies to “SEARCH FOR &REFUSE all deliveries of fentanyl,” a deadly synthetic opioid. American officials have long blamed China for the influx of fentanyl and related drugs reaching U.S. borders — sent directly and trafficked via other countries — while federal efforts to limit (if not stop outright) their import have long been underway. ….your companies HOME and making your products in the USA.

To investigate the pathogenicity of two newly isolated SVV strains (GD-S5/2018 and GD04/2017) in China, experimental infections of mice and pigs were performed. SVV GD-S5/2018 was lethal to mice infected by intramuscular, intraperitoneal, or oral routes, while SVV GD04/2017 was avirulent without causing any discernible clinical signs in mi...

Alejandra Tortorici, David VeeslerAbstractCoronaviruses (CoVs) have caused outbreaks of deadly pneumonia in humans since the beginning of the 21st century. The severe acute respiratory syndrome coronavirus (SARS-CoV) emerged in 2002 and was responsible for an epidemic that spread to five continents with a fatality rate of 10% before being contained in 2003 (with additional cases reported in 2004). The Middle-East respiratory syndrome coronavirus (MERS-CoV) emerged in the Arabian Peninsula in 2012 and has caused recurrent outbre...

Publication date: Available online 23 August 2019Source: Journal of Theoretical BiologyAuthor(s): Amir Hossein Amiri Mehra, Iman Zamani, Zohreh Abbasi, Asier IbeasAbstractThis paper presents a new Susceptible, Exposed, Infected, Asymptomatic, and Recovered individuals (SEIAR) model for influenza considering a dynamic population. In the given model, the possibility of transmission of asymptomatic individuals (infectious with no visible symptoms) to infected individuals (infectious exhibiting symptoms) is considered. The basic reproduction number and the equilibrium points of the new model are given while the stability of th...

In this study, a Δ2 mutant that deletion of D2 fragment in parental virulent strain HN016 was constructed, and the safety, stability, immunogenicity, and growth characteristics, as well as the virulence mechanism of Δ2 mutant were evaluated. The results showed that Δ2 mutant was not pathogenic to tilapia, and the virulent revertants were not observed after 50 generations of passage. The RPS reached 96.11% at 15 days and 93.05% at 30 days, respectively, after intraperitoneal injection, while RPS reached 74.80% at 15 days and 53.16% at 30 days, respectively, after oral immunization. The growth of Δ2 m...

HeegaardAbstractTightened regulations and an environmentally friendly approaches in fish production have greatly reduced the use of antibiotics but green solutions are continuously being explored. The use of functional feed may have a potential in the aquaculture sector in securing biomass and minimizing the loss from disease. In the present study, we tested the concept that blood from the fish slaughterhouse can be used for mass...
