Now a 4-year study which analysed over 540 000 births in Greater London (Fig. 1) shows that 3% of all full-term babies born with low birthweight (<2500 g) is attributable to air pollution from London traffic. The study found a 15% increase in risk of low birthweight for every ...
In the case of viruses, mutations may lead to different phenotypic changes. Mutations which affect the third base in a code word may be completely silent and have no influence on virus replication. This is the case if the mutation hits a triplet which codes for an amino acid for which ther...
Genetic Variation During Persistent Reovirus Infection: Presence of Extragenically Suppressed Temperature-Sensitive Lesions in Wild-Type Virus Isolated from Persistently Infected L Cells To determine whether the ts(+) phenotype of the virus was due to intragenic reversion or to the presence of an extrag...
This hairpin TpC site is a highly optimal substrate for A3A, as we previously reported20. However, we were surprised to see that when we tested a 5′-AC in the hairpin context, A3A showed significant and highly reproducible enzymatic activity, even higher than the activity on the non-...
Canada The Chudley–Lowry syndrome (ChLS, MIM 309490) is an X-linked recessive condition characterized by moderate to severe mental retardation, short stature, mild obesity, hypogonadism, and distinctive facial features characterized by depressed nasal bridge, anteverted nares, inverted-V-shaped upper...
Marek's disease virus (MDV) is an oncogenic herpesvirus that afflicts chickens with the disease known as Marek's disease (MD). This virus induces tumors, nerve lesions, immunosuppression, and death of affected birds. Vaccines are the primary control method for MD but, due to the periodic evo...
food, and pickled vegetables. However, the incidence rates of ESCC are broadly in decline due to improved living standards in China. In Western countries, the reduction of ESCC incidence is considered primarily due to a large-scale decline in cigarette smoking6. For certain types of cancer, ...
the first report from Wuhan, there is no complete convergence of virus infection in the world and SARS-CoV-2 infection causes high rate of morbidity and mortality2. In the prolonged SARS-CoV-2 infection, it is quite important to investigate whether the virulence of the virus have been ...
