Fasciola gigantica: Comparison of the tegumental ultrastructure in newly excysted metacercariae and in vitro penetrated juvenile flukes indicates intracellular sources of molecules with vaccinal and immunomodulatory potential
(Elsevier, 2019)Using in vitro procedures to prepare newly excysted metacercariae and gut-penetrated juvenile Fasciola gigantica, the ultrastructural features of the tegumental syncytium and perikarya of these ephemeral stages in the ... -
Fasciola gigantica: ultrastructural cytochemistry of the tegumental surface in newly-excysted metacercariae and in vitro-penetrated juvenile flukes informs a concept of parasite defence at the interface with the host
(Elsevier, 2019)Cytochemical staining techniques were carried out en bloc with in vitro excysted and gut-penetrated Fasciola gigantica larvae in order to visualise the glycocalyx of the tegument, a structure which comprises the parasite ... -
Fate processes of chlorobenzenes in soil and potential remediation strategies: A review
(Elsevie, 2017-06-30)Abstract Chlorobenzenes (CBs) are a group of organic pollutants that pose a high environmental risk due to their toxicity, persistence and possible transfer in the food chain. Available data in literature show that CBs ... -
