Satisfaction and perceptions about aspects of the city that affect health, by socioeconomic status, 2010-2019, in Lima.

We aimed to characterize the satisfaction and perceptions of the residents of Lima about different aspects of urban life that can affect their quality of life and health, identifying differences by socioeconomic status (SES) and changes over time. A secondary data analysis of the "Lima Cómo Vamos" survey was conducted between 2010 and 2019. Results are reported through percentages, with differences between SES for each year and between years.

Novel purification method for recombinant 3AB1 nonstructural protein of foot-and-mouth disease virus for use in differentiation between infected and vaccinated animals.

An indirect enzyme-linked immunosorbent assay (ELISA) was developed for differentiation of animals infected with foot-and-mouth disease virus (FMDV) from vaccinated animals. The test was based on a highly pure and concentrated preparation of recombinant 3AB1 protein obtained by expression in a prokaryotic system, protein separation by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and electro elution. Experimental- and field-serum samples from naive, vaccinated, and infected cattle were tested for anti3AB1 antibody using the ELISA.
