ScienceDirect - International Journal of Pharmaceutics : Dendrimer toxicity: Let's meet... - 9 views

  •  
    Dendrimers are well-defined, versatile polymeric architecture with properties resembling biomolecules. Dendritic polymers emerged as outstanding carrier in modern medicine system because of its derivatisable branched architecture and flexibility in modifying it in numerous ways. Dendritic scaffold has been found to be suitable carrier for a variety of drugs including anticancer, anti-viral, anti-bacterial, antitubercular etc., with capacity to improve solubility and bioavailability of poorly soluble drugs. In spite of extensive applicability in pharmaceutical field, the use of dendrimers in biological system is constrained because of inherent toxicity associated with them. This toxicity is attributed to the interaction of surface cationic charge of dendrimers with negatively charged biological membranes in vivo. Interaction of dendrimers with biological membranes results in membrane disruption via nanohole formation, membrane thinning and erosion.

      Pro - Argument #1
  • The American Library Association encourages schools and libraries to think twice before keeping kids off social media, saying such prohibition "does not teach safe behavior and leaves youth without the necessary knowledge and skills to protect their privacy or engage in responsible speech." Their policy statement on the topic says that instead of restricting access, librarians and teachers "should educate minors to participate responsibly, ethically and safely."

  • Perhaps the biggest objection to widespread use of social sites is the likelihood that kids will encounter irrelevant or even offensive material--a fear that many teachers say is overblown. While the Web can seem like "a sea of pornography and idiots," says James Lerman, the author of several books on educational technology, schools must help students figure out how to navigate it so they "can get to the good stuff" that's applicable to school.

      con - Argument #2
  • There is an epidemic of under-the-desk text messages during class, a virtual economy of exam pictures posted to Facebook, a trade in school fight videos on YouTube, they say. To combat it, the county school board voted Thursday to ban cellphones and other electronics during the school day, even as many school systems across the country are loosening their rules.
