Biosafety considerations associated with molecular farming in genetically modified plants

The production in genetically modified plants of recombinant proteins for pharmaceutical or industrial use, also referred to as "plant molecular farming", deserves increasing interest due to its potential advantages. However, this type of application of genetic engineering also raises some biosafety concerns, in particular regarding aspects such as transgene spread in the environment or accidental...

Phytochemicals as chemotherapeutic agents and antioxidants: Possible solution to the control of antibiotic resistant verocytotoxin producing bacteria

The interest in plants with antimicrobial properties has been revived due to current problems associated with the use of antibiotics with the increased prevalence of multidrug resistant (MDR) bacterial strains. Some emerging species of bacteria such as Escherichia coli 0517: H7 and Acinetobacterspecies that are verocytotoxin producers present further chemotherapeutic challenges because of the increased...

Hesperidin, a natural citrus flavanone, alleviates hyperglycaemic state and attenuates embryopathies in pregnant diabetic mice

In this study, we attempted to investigate the effect of hesperidin, a natural antioxidant citrus flavanone, on diabetes-induced embryopathies in mice. Streptozotocin (STZ) was injected intraperitoneally in 60 mg/kg bw/day for 3 consecutive days to induce diabetes in virgin females. 72 h later, mating was applied and hesperidin was orally given to pregnant diabetic mice in 20 ppm from the 1st to the 18th day...
