Possible Breakthroughs in Cancer and AIDS Research

FortKnox writes "Two possible medical breakthroughs have come to light in recent days. In Australia, it was discovered that pineapple extract can stimulate the body to attack cancer cells. And in Japan, Kumamoto University researchers have developed a drug that will block cells from the AIDS virus, thus making something akin to an AIDS vaccine." From the Australian news: "One of the molecules, CCZ, stimulates the body's immune system to target and kill cancer cells, the other, CCS, blocks a protein called Ras, which is defective in 30 percent of all cancers. QIMR researcher Tracey Mynott said her team had set out to find why the enzyme-rich bromelaine crush had such strong effects on biological material."

    At least it's not a dupe.

      Sure, in 1985, they knew that bromelaine would suppress tumor growth. I don't think they had identified the particular molecules that were responsible, though, which is what will lead to future viable treatments. It's not like you can inject pineapple extract into a living patient.

    My guess is the virus can still enter the bloodstream...

    Yes, but as a virus, it's unable to reproduce if it cannot enter the cells.

    How everything will work in the actual patient...

    This HIV study was a 40 patient clinical trial. Pretty damn close to actual patients if you ask me.

    yikes. having personally seen the effects of HIV infection and AIDS in people who subscribe to the AIDS Denialist school of thought, i felt compelled to reply to this posting.

    bottom line:

    1. CD4+ T-lymhocyte counts and HIV viral loads have been negatively and positively (respectively) correlated with survival in virtually every patient population ever studied.

    2.highly active anti-retroviral therapy (HAART) has been shown to significantly reduce mortality in HIV-infected individuals.

    we practice evidence-based medicine in the united states. you can try to poke holes in the virology if you want to (i'm not a virologist) but you can't argue with epidemiology.

    the theory that HIV is the causative pathogen in AIDS has not been disproven in any peer-reviewed publication that i have ever seen.

    we know how to treat these patients and turn AIDS into a chronic rather than a fatal illness.

    here is a more complete resource on the debate.

    Perhaps it's a fundamental flaw in news reporting and how it rarely interacts well with scientific researchers that explain your jaded state.

    For a number of years, I worked in biological research, and twice I had the (dis)pleasure of interacting with reporters.

    If you tell them there is an observed improvement in 15% of all cases, then it's a cure. If you tell them there is a statistical corelation, then it "causes". If you tell them about the science, they will latch onto the most trivial detail and make it the entire point of your research effort.

    It's because most Science doesn't make good news. Good news (at least as it seems to be presented these days) gives the audience the aura of understanding without any actual understanding. In other words, good news asks the audience to learn almost nothing, but be entertained nonetheless.

    To prove my point, cancer is the misbehavior of the patient's own cells, yet nearly everyone refers to it as an item that is "caught" like a transmittable disease, and "cured" like a bacterial infection. Non-scientists rarely differentiate between the reasons why our cells misbehave, instead they concentrate on where the misbehaving cells are located. Finally, people tend to totally ignore the effects of known carcinogens because they have been bombared with so much bad news that started off as:

    When rats eat a diet of 80% fat, they have a 12% higher risk of contracting a cancer over a 3 year lifespan, 40% of those cases are self-arresting producing only benign tumors.

    becomes:

    Scientists find that diets high in fat significantly increase the risk of cancer. People who eat pizza, french-fries, and mayonnaise are at risk, and are 60% more likely to die. So it's time to stock up on those veggies.

    No mention that it's rats, not people. No mention that it's a lifetime diet of 80% fat. No mention that it only affects 12% of the rat population studied. No mention that 60% of the affected die, leading to an increase of mortailty of only 8% or so.

    Sometimes (just like in my example) they do it so badly that they have internal logical errors in their own reporting. 60% more likely to die (as opposed to 100% certainty that we will eventually die).

    So be skeptical, but please don't be skeptical of the science, unless you are one of the few people who actually bother to read the publications without the mind-numbing news filter placed on top of it.

    Just an FYI, there are cases being reported that the incubation period has dropped to just several months.

    Yikes!
