Abstract

The study was carried out for five months from November, 2014 to April, 2015 during which dust fall (particulate matter) was monitored in University of Ilorin, University of Ibadan and Kwara State University motor parks. Dust fall monitoring was carried out using Single open bucket sampler based on American Standard Test Method (ASTM D1739). The average dust fall depositions were found to be 1122.15 ± 50, 627.648 ± 34, and 316.322 ± 16 mgm-2day-1 for University of Ilorin (Un), Kwara State University (Kw) and University of Ibadan (UI) sites respectively. It was observed that unpaved surface and number of moving vehicles were the main factors for increased or decreased in dust fall concentrations. There was correlation between some meteorological parameters (rain fall, wind speed, temperature and relative humidity) and dust fall depending on the site.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
