Pterostilbene an anticarcinogenic breakthrough

Posted by in categories: biotech/medical, innovation

Pterostilbene showing some interesting potential for treating cancer.

One of the most common forms of cancer in the hematologic system is Multiple myeloma (MM) which affects plasma cells, a type of white blood cell that produces antibodies. With advanced symptoms bone pain, bleeding, frequent infections, and anemia may occur.

In studies, Pterostilbene has shown anti-inflammatory and anticarcinogenic properties which has led to the improved function of healthy cells and the inhibition of malignant cells. So far its anticarcinogenic action has been reported for lung, breast and prostate cancers. Today we will look at the latest research showing how it could be used to treat cancer patients.

Ageing is natural. Rejuvenation is not

Posted by in categories: biotech/medical, genetics, life extension

Some people object we shouldn’t cure ageing because it is natural. Well, so is malaria, for example…

You know, I may even agree ageing is ‘natural’. If we define natural as something that happens spontaneously, without external intervention, as a consequence of chemical and physical interactions, then yes, ageing is natural. This is not a great argument in favour of ageing, though, because there are very many perfectly natural things that are really bad for you, ranging on the badness spectrum pretty much anywhere from ‘mildly upsetting’ to ‘catastrophically apocalyptic’: mosquito bites, genetic diseases, viral diseses, earthquakes, tsunamis, stars going nova, being eaten by lions, cancer, a pidgeon pooing on the fancy suit you rented for your wedding precisely when you say ‘I do’, bacterial infections, and so on. So, okay, maybe ageing is natural. So what? It is also the number one cause of suffering and diseases in the western world. Frankly, I don’t give a damn if it is natural or not. It’s still pretty bad.

Speaking of rejuvenation being not natural, I could nitpick a lot. I could ask, what is ‘not natural’? Is it anything human made? Then what about things made by animals? For example, if a building is ‘not natural’, what about a beehive then? Natural or not? Given we humans have a natural tendency to tweak things around to make them work the way we want, wouldn’t rejuvenation be our natural response to the problem of ageing, just like medicines are our natural response to the problem of diseases?

How It Works: A System That Reverses Paralysis

Posted by in categories: biotech/medical, neuroscience

For decades, researchers have been seeking ways to help the millions of people with spinal cord injuries regain control of their limbs, with frustratingly little success. The new device provides a rare glimmer of hope. Scientists at the University of Louisville’s Kentucky Spinal Cord Injury Research Center, where Meas and three other patients received their im­plants, speculate that the stimu­lation may be reawakening connections between the brain and the body. “There’s residual circuitry that we can recover that no one realized was possible to do,” says Reggie Edgerton, director of the Neuromuscular Research Laboratory at the University of California, Los Angeles. “We were shocked.”

Some of the benefits, such as better bowel and bladder control and improved blood pressure, remain even when the device is switched off. Electrical stimulation isn’t a cure, of course. The patients still can’t walk. And the stimulation must be customized for each individual, a time-consuming process. But it’s an enormous advance nonetheless. Says Edgerton, “It opens up a whole new mechanism of recovery.”

Breath test for stomach and esophageal cancers shows promise

Posted by in categories: biotech/medical, electronics

For several years, Professor George Hanna from Imperial College London has been directing work toward the development of a test that can detect cancers of the esophagus and stomach by measuring the levels of five chemicals in a patient’s breath. These chemicals are butyric, pentanoic and hexanoic acids, butanal, and decanal, which previous research has identified as pointers to the presence of stomach or esophageal cancer.

In 2015, Professor Hanna announced the results of the first clinical study analyzing the breath samples of 210 patients. The patents exhaled into a breathalyzer-like device, which used a selected ion flow tube mass spectrometer to detect the presence of any of the five aforementioned chemicals in the breath sample. The 2015 study achieved a 90 percent accuracy rate in correctly identifying the two cancers, and a recently completed, broader study has also proven successful.

The new study collected samples from 335 people across four London hospitals. Around half of the group had been diagnosed with stomach or esophageal cancer and the other half had shown no evidence of cancer after having an endoscopy. After analyzing all the samples, the new breath test achieved an 85 percent accuracy rate, correctly identifying those both with and without cancer.

Pull A Body Apart With This Augmented Reality App

Posted by in categories: augmented reality, biotech/medical

Looking for that perfect gift for the medical student in your life? Search no more.

Is it wise to make medical students feel like renegade fictional genius Tony Stark, magically waving human bodies apart like the holographic diagrams in the Iron Man basement lab? Should we use technology to make millennials feel like superheroes? Stop asking difficult philosophical questions and look at how cool this is.

This augmented reality app is called Project Esper. It uses hand gestures to allow the users move and study anatomy. Users can pull the human body apart and investigate the organs and limbs piece by piece. Look—just look at this magical Star Trek karate:

Researchers design 3D system to detect circulating tumor cells

Posted by in category: biotech/medical

Someday, we will have glasses or contacts that will be able to detect tumors and notify us or even contact doctor’s office to set up the appointment for us.

Researchers have shown that they could efficiently capture and simultaneously filter out the circulating tumor cells (CTCs) permanently from cancer patients’ whole blood, which otherwise could gain access into the blood and invariably cause metastasis.

LSD alters perception via serotonin receptors

Posted by in categories: biotech/medical, media & arts, neuroscience

Interesting study on brain receptors.

Researchers from UZH have discovered how the perception of meaning changes in the brain under the influence of LSD. The serotonin 2A receptors are responsible for altered perception. This finding will help develop new courses of pharmacotherapy for psychiatric disorders such as depression, addictions or phobias.

Humans perceive everyday things and experiences differently and attach different meaning to pieces of music, for instance. In the case of psychiatric disorders, this perception is often altered. For patients suffering from addictions, for instance, drug stimuli are more meaningful than for people without an addiction. Or patients with phobias perceive the things or situations that scare them with exaggerated significance compared to healthy people. A heightened negative perception of the self is also characteristic of depressive patients. Just how this so-called personal relevance develops in the brain and which neuropharmacological mechanisms are behind it, however, have remained unclear.
