RNA interference: a potential revolution in disease therapy

Gene therapy is the most recent face of modern biotechnology, which has shown promise of disease diagnosis and management at a newer and the most sophisticated level. The reason of enormous interest in gene therapy lies in the fact that most of lethal pathologies including hepatitis B and C, AIDS and carcinogenesis are refractory to contemporary treatments. These techniques, at least in controlled environment, allow turning on and off various genomic sequences. Relevant to this subject, RNA interference [RNAi] is the most recent, highly precise method to silence almost any gene of choice. Currently, RNAi for various disorders is being tried in humans; if this therapeutic strategy works at clinical level as well, it would be possible to design therapies against certain intractable pathologies including hepatitis C and AIDS. This is a review arti

Technologic advances in robotic surgery

Medical science has achieved enormous accomplishments during the past couple of decades. These advances encompass the list of techniques involving manipulations of DNA and stem cells to minimally invasive techniques. The recent advances in integration of computer sciences, biomechanics and electronic miniaturization have made it possible to make the surgical techniques less invasive and highly precise. Much progress has been made in integrating robotic technologies with surgical instrumentation, as evident by thousands of successful robot-assisted surgical procedures. Such advances will enable continued progress in surgical instrumentation and, ultimately, surgical care
