This low number may be connected with the lack of screening tests and the asymptomatic course of infection. Currently,mother-toinfant transmission is the most common cause of HCV infection amongst children in developed countries. It is important to introduce routine screening tests for HCV in pregnant women. The risk of vertical transmission of HCV is estimated at approximately 5%(3%-10%). Currently,we do not have HCV transmission prevention methods. Some factors could potentially be eliminated by elective caesarean section. Currently,the method of prevention of perinatal HCV infection is the early identification and effective treatment of infections in young women in the preconception period. We describe genetic tests(IL-28 B single nucleotide polymorphisms) to identify children with an increased chance of spontaneous clearance or sustained virologic response achievement and vitamin D level as a potential predictor of treatment response in children. It is also important to develop non-invasive tests that can predict liver fibrosis. The existence of differences in the mechanisms leading to liver injury between children and adults creates new perspectives of action to reduce liver disease progression in children in the early years of life.展开更多

[ Methods] The primers for heat resistant nuclease gene （nuc） of Staphylococcus aureus were designed for establishing the LAMP method for rapidly detecting Staphylococcus aureus. [ Results ] The results of LAMP detection on Staphylococcus aureus in various dairy products were completely identical with that by bacterial isolation test; meanwhile it has a high specificity and a 10-fold sensitivity over the hemi-nested PCR. [ Conclusion] LAMP can be used for the detection of Staphylococcus aureus in dairy products.展开更多

We prove that the WA ε property is equivalent to the WBS property and the g NUC ε (resp., g NUC) spaces are equivalent to the NUC ε (resp., NUC) spaces possessing the BS property. So we obtain a characterization of the NUC ε (resp., NUC) spaces possessing the BS property.展开更多
