Functional analysis of a novel parasitic nematode-specific protein of Setaria digitata larvae in Culex quinquefasciatus by siRNA mediated RNA interference.

Background: Functional analysis of animal parasitic nematode genes is often quite challenging due to the unavailability of standardised in vitro culture conditions and lack of adequate tools to manipulate these genes. Therefore, this study was undertaken to investigate the suitability of Culex quinquefasciatus, as an in vivo culture platform for Setaria digitata larvae and RNA interference (RNAi), as a post-transcriptional gene silencing tool to study the roles of a vital gene that encodes a novel parasitic nematode-specific protein (SDNP).

Results: The red colour fluorescence detected following RNAi injection to the thorax of C.

Development of siRNA mediated RNA interference and functional analysis of novel parasitic nematode-specific protein of Setaria digitata.

Despite the differences of the host, parasitic nematodes may share commonalities in their parasitizing genes. Setaria digitata novel protein (SDNP) is such an entity which is parasitic nematode-specific and having sequence similarities with those of W. bancrofti, B.

Acquired haemophilia A associated with autoimmune thyroiditis: a case report.

Introduction: Acquired haemophilia A is a rare life- and limb-threatening bleeding disorder if left untreated. Autoimmune thyroiditis is an autoimmune disorder that can be rarely associated with acquired haemophilia. Here we report a case of a 60-year-old woman presenting with cutaneous and muscle haematomas secondary to acquired haemophilia A in association with autoimmune thyroiditis, who was successfully treated with recombinant activated factor VII and immunosuppression.
