ABSTRACT The ARTIC Network provides a common resource of PCR Collections primer sequences and recommendations for amplifying SARS-CoV-2 genomes.The initial tiling strategy was developed with the reference genome Wuhan-01, and subsequent iterations have addressed areas of low amplification and sequence drop out.Recently, a new version (V4) was relea
Coumarins are widely distributed substances in plant species that promote phytotoxic effects, allowing them to be exploited as herbicides less harmful to the environment, since many invasive species have demonstrated resistance to commercially available products.The derived coumarins used in this study had not been tested in plant models and their
OBJECTIVE: Limited surveys and anecdotal data indicate that trachoma is endemic in the states of Eastern Equatoria and Upper Nile in southern Sudan.However, its magnitude and geographical distribution are largely unknown.We conducted surveys to ascertain the prevalence and geographical distribution of trachoma, and to identify targets for control i
