Highly effective new anti-cancer drug shows few side effects in mice

When taken by mouth, the drug was well tolerated with limited toxicity. An intravenous form, delivered within a liposome, was just as effective with fewer side effects. Both approaches — described in the October 22, 2014 issue of Science Translational Medicine — led to complete regression of transplanted tumors. …

Promising new cancer therapy uses molecular ‘Trash Man’ to exploit a common cancer defense

Cancer therapies cause unwanted proteins to accumulate in cancer cells, which can trigger a form of cell suicide known as apoptosis. To survive, the cells break down the excess proteins through autophagy, from a Greek term meaning “self eating.” In a study recently published in the journal Molecular and Cellular Biology, scientists induced autophagy using the anti-tumor drug obatoclax while simultaneously blocking the production of p62 using a drug known as a cyclin-dependant kinase (CDK) inhibitor. …

‘Intelligent knife’ tells surgeon which tissue is cancerous

In the first study to test the invention in the operating theatre, the "iKnife" diagnosed tissue samples from 91 patients with 100 per cent accuracy, instantly providing information that normally takes up to half an hour to reveal using laboratory tests. The findings, by researchers at Imperial College London, are published today in the journal Science Translational Medicine. The study was funded by the National Institute for Health Research (NIHR) Imperial Biomedical Research Centre, the European Research Council and the Hungarian National Office for Research and Technology. …

Is there a hidden scandal lurking in ObamaCare?

America, we are in trouble – and we better wake up and act.   Just look at the state of affairs in our country today.  We are seeing scandal after scandal, with the Benghazi controversy, the IRS targeting of conservative groups, and the freedom of the press being challenged by the Department of Justice. The word scandal is defined by the Oxford Dictionary as “an action or event regarded as morally or legally wrong and causing general public outrage.”  I think the implementation of ObamaCare fulfills that definition. I remember back in 2010 when then-Speaker of the House Nancy Pelosi made her infamous remark about the Affordable Care Act, saying “we have to pass the bill so that you can find out what’s in it....” Well the bill has been passed, and now we see what’s in it: An utter mess with incomprehensible rules. If we compare the assertions the president made about ObamaCare when it was first introduced to the current bill as it has been passed today, we find that all the president’s guarantees regarding ObamaCare are not there.   The truth of the matter is that we were not fully informed.  For example, President Obama maintained that this bill would lower the cost of health care, especially in regards to insurance premiums.  That is simply not true.  Many different analyses clearly show that in some markets, insurance premiums can increase as high as 30 to 40 percent. One of the main reasons for this increase can be attributed to all the hidden taxes that this bill contains, which the insurance industry will likely pass on to consumers.   Another false guarantee given by the administration was that individuals would be able to keep their doctors and current level of service through ObamaCare.  Again, this is not true. The so-called insurance exchanges being set up in many states by the federal government will most likely create a non-competitive environment, meaning patients who cannot afford other types of insurance will be forced to buy insurance from the government.  And if their current doctors are not willing to participate in that single-payer health care system, these patients will ultimately lose the guarantee of keeping their own doctors. So what does this all mean? It means that if everything goes according to the president’s plan, the health care landscape is going to completely change over the next decade. A potential scenario is that private doctors will be employees of one large health care system. Health standards such as maintaining an ideal weight and eliminating habits like drinking alcohol and soda will be placed on families so that they can qualify for health care.  So in other words, your individual freedom will be targeted. I know many people argue that it’s better if everyone has health insurance and maintains a healthy lifestyle.  Yes it is, but I still believe that an individual’s health care should not be dictated by the government. Instead it should be a choice made by the individual and his or her health provider. Many senior politicians and consultants have found as of late that ObamaCare is a train wreck.  And yet, the person in charge of implementing ObamaCare, United States Secretary of Health and Human Services Kathleen Sebelius, continues to drive the train forward.  Rather than work with leaders who are suggesting changes ,she has decided to enlist the help of the private sector in getting donations to help fund ObamaCare.   Many have questioned this move, but one thing Secretary Sebelius knows is how to organize her community of followers.  Recently, she has teamed up with Nancy-Ann DeParle, former director of the White House Office of Health Reform, placing her in charge of asking insurance companies to donate $1 million or more to Enroll America, a non-profit organization promoting enrollment in the subsidized insurance markets, according to a report from Politico. You see, folks, ObamaCare is all about politics and control, and to me, that is a formula for disaster.  This is something that should not be taken for granted but rather openly evaluated by the American public.source : http://www.foxnews.com/health/2013/05/29/is-there-hidden-scandal-lurking-in-obamacare/

Shape-shifting nanoparticles flip from sphere to net in response to tumor signal

Spherical nanoparticles labeled with red or green dye shift their shapes and accumulatte into netlike structures when they encounter a protease secreted by some kinds of cancerous tumors (Click on image for larger view). Targeting treatments specifically to cancerous or other diseased cells depends on some means of accumulating high levels of a drug or other therapeutic agent at the specific site and keeping it there. Most efforts so far depend on matching a piece of the drug-delivering molecule to specific receptors on the surface of the target cell. …
