Abstract:
... Neospora caninum represents an obligate intracellular parasite that belongs to the phylum Apicomplexa and is a major abortive agent in bovines. During merogony, N. caninum tachyzoites invade and proliferate in host cells in vivo, including endothelial cells of lymphatic and blood vessels. The egress at the end of the lytic cycle is tightly regulated in apicomplexans. Evidence in Toxoplasma gondii ...

Abstract:
... Circulating tumor cells (CTCs) can be the seeds of tumor metastasis and are closely linked to cancer-related death. Fast and effective detection of CTCs is important for the early diagnosis of cancer and the evaluation of micrometastasis. However, the extreme rarity and heterogeneity of CTCs in peripheral blood make sensitive detection of CTCs a big challenge. In this paper, a TiO₂-based surface-e ...

Abstract:
... Rift Valley fever (RVF) is an emerging transboundary, mosquito-borne, zoonotic viral disease caused by a single serotype of a virus belonging to the Phenuiviridae family (genus Phlebovirus). It is considered an important threat to both agriculture and public health in endemic areas, because the virus, transmitted by different mosquito genera, leads to abortions in susceptible animal hosts especial ...
