Methods, potentials, and limitations of gene delivery to regenerate central nervous system cells

This review evaluates methods, success and limitations of transgenes delivery in central nervous system (CNS). Both viral and nonviral (such as liposome mediated) methods, expression and stability of transgenes have been discussed. The controlled expression and delivery techniques of transgene at the injured or diseased sites have also been discussed. Mifepristone (RU486) and tetracycline-based switch system for controlled expression could be a very useful tool for clinical purposes. Here we emphasized the importance and consequences of viral- and nonviral-mediated transgenes transfer and therapeutic ability along with advantages of controlled expressions

In-vitro scolicidal activity of Mallotus philippinensis (Lam.) Muell Arg. fruit glandular hair extract against hydatid cyst Echinococcus granulosus

AbstractObjectiveTo investigate new scolicidal agent from natural resources to cope with the side effects associated with synthetic drugs in Echinococcosis.MethodsThe scolicidal potential of methanolic fruit powder extract (10 and 20 mg/mL) of Mallotus philippinensis (M. philippinensis) was investigated. Viability of protoscoleces was confirmed by trypan blue exclusion method, where mortality was observed at concentration of 10 and 20 mg/mL in 60 min treatment against Echinococcus granulosus (E. granulosus), under in-vitro conditions with reference to the known standard drug Praziquantel®.ResultsAt concentration 10 and 20 mg/mL, the mortality rate was observed 97% and 99% respectively for 60 min treatment; while up to 93% mortality was observed with 20 mg/mL for only 10 min treatment. The concentration above 20 mg/mL for above 2 h showed 100% mortality, irrespective of further incubation.ConclusionsAs compared with the standard anti-parasitic drug Praziquantel our extract has significant scolicidal activity with almost no associated side effects
