INFECTION AND TRANSMISSION OF RIFT VALLEY FEVER VIRUSES LACKING THE NSS AND/OR NSM GENES IN MOSQUITOES: POTENTIAL ROLE FOR NSM IN MOSQUITO INFECTION.

BACKGROUND: Rift Valley fever virus is an arthropod-borne human and animal pathogen responsible for large outbreaks of acute and febrile illness throughout Africa and the Arabian echofix spring reverb Peninsula.Reverse genetics technology has been used to develop deletion mutants of the virus that lack the NSs and/or NSm virulence genes and have be

Supernumerary teeth and tooth agenesis are common morphological anomalies in humans.We previously obtained evidence that supernumerary maxillary incisors form as a result of the successive development of the rudimentary maxillary incisor tooth germ in Usag-1 null mice.The development of tooth germs is arrested in Runx2 null mice, and such mice also

The use of deicing compounds and car exhaust have a negative impact on the main indicators of arable fertility.The purpose of the research was to study the physical properties of arable land and crop yields at different distances from the roads.Four soils were studied: sod-podzolic, gray forest, leached chernozem and meadow saline.Soil sampling was
