We established a cold-adapted infectious bronchitis virus (BP-caKII) by passaging a field virus through specific pathogen-free embryonated eggs 20 times at 32 °C. We characterized its growth kinetics and pathogenicity in embryonated eggs, and…

Objective To measure the effects of the tier system on the COVID-19 pandemic in the UK between the first and second national lockdowns, before the emergence of the B.1.1.7 variant of concern.Design This is a modelling study combining estimates of…

Recent nosocomial transmission events of emerging and re-emerging viruses, including Ebola virus, Middle East respiratory syndrome coronavirus, Nipah virus, and Crimean−Congo hemorrhagic fever orthonairovirus, have highlighted the risk of…

Our ability to respond appropriately to infectious diseases is enhanced by identifying differences in the potential for transmitting infection between individuals. Here, we identify epidemiological traits of self-limited infections (i.e. infections…

Our objective was to estimate the individual willingness to pay (WTP) for a COVID-19 vaccine and evaluate its predictors in the United States. A double-bounded dichotomous choice contingent valuation with open-ended question technique was implemented…

In the end of December 2019, a novel coronavirus was identified as the cause of pneumonia cases in Wuhan, China. The disease was later named as COVID-19 (coronavirus disease 2019) and the causative agent was designated as SARS-CoV-2 (severe acute…

Research started with the pneumonia cases that emerged in Wuhan, China in December 2019 and whose cause could not be determined clearly, revealed the existence of a new type of coronavirus. The infectious agent was named SARS-CoV-2 (severe acute…

Protein adsorption is influenced by many factors such as temperature, pH, protein size and structure, or surface energy and roughness, among others. Self-assembled monolayers (SAMs) and the Langmuir-Blodgett (LB) technique are two of the techniques…

Este texto aborda las nocividades ambiental y alimentaria como temáticas que, a pesar de sus propias características, constituyen una parte importante del universo al interior del cual la bioética se desarrolla. En este sentido las nocividades…
