A new experimental system sheds light on how memory loss may occur

Posted by in categories: bioengineering, biotech/medical, genetics, neuroscience

Two interconnected brain areas — the hippocampus and the entorhinal cortex — help us to know where we are and to remember it later. By studying these brain areas, researchers at Baylor College of Medicine, Rice University, The University of Texas MD Anderson Cancer Center and the National Cancer Institute have uncovered new information about how dysfunction of this circuit may contribute to memory loss in Alzheimer’s disease. Their results appear in Cell Reports.

“We created a new mouse model in which we showed that spatial memory decays when the entorhinal cortex is not functioning properly,” said co-corresponding author Dr. Joanna Jankowsky, associate professor of neuroscience at Baylor. “I think of the entorhinal area as a funnel. It takes information from other sensory cortices — the parts of the brain responsible for vision, hearing, smell, touch, and taste — and funnels it into the . The hippocampus then binds this disparate information into a cohesive memory that can be reactivated in full by recalling only one part. But the hippocampus also plays a role in spatial navigation by telling us where we are in the world. These two functions converge in the same cells, and our study set out to examine this duality.”

The new mouse model was genetically engineered to carry a particular surface receptor on the cells of the entorhinal cortex. When this receptor was activated by administering the drug ivermectin to the mice, the cells of the entorhinal cortex silenced their activity. They stopped funnelling information to the hippocampus. This system allowed the scientists to turn off the entorhinal cortex, and to determine how this affected hippocampal function.

How liquid aspirin could help fight brain cancer: Special version of the drug found to be ten times more effective at killing cancer cells than chemotherapy

Posted by in categories: biotech/medical, neuroscience

A drink containing liquid aspirin could extend the lives of thousands of brain cancer patients, according to breakthrough research.

British experts have found that the simple drug can cross the ‘blood-brain barrier’ — a hurdle which has so far stopped cancer drugs attacking brain tumours.

Scientists will today announce the results of early tests which show liquid aspirin is ten times more effective than any existing chemotherapy at killing brain cancer cells.

Scientists Want to Reprogram Human Cells to Stop Death

Posted by in category: biotech/medical

Different species of animals either live a very long time or do not die of old age. Some cases are the tortoise & lobster species that live to be over 130 years old naturally and don’t usually die unless they get sick or are killed.

After we grow up our cells ultimately stop self-replicating. A researcher named Leonard Hayflick figured out that each of our cells divide around 50 times and then they stop. Once all of our cells stop duplicating we start to deteriorate and then ultimately die. This finding showed that we are in fact programmed to die biologically.

The Top Ten Reasons I Believe Vaccine Safety Is an Epic Mass Delusion

Posted by in categories: biotech/medical, ethics, existential risks, government, health, life extension, policy, rants, science, scientific freedom

Its painful to bear views that make many think I’m an imbicile and dislike me. So please, if anybody has a rational argument why any of this is wrong, I beg to be enlightened. I’ve set up a diagram for the purpose that will support you to add your criticism exactly where it is pertinent. https://tssciencecollaboration.com/graphtree/Are%20Vaccines%20Safe/406/4083

(1) The National Academy’s Reviews Of Vaccine Safety
The Institute of Medicine of the National Academies has provided several multi-hundred page surveys studying the safety of vaccines, but rather than reassuring, these itemize some iatrogenic conditions being caused, and pronounce the scientific literature inadequate to say whether most others are. The 2011 Institute of Medicine (IOM) Review[1] looked at 146 vaccine-condition pairs for causality, reporting:

  • 14 for which the evidence is said to convincingly support causality, the vaccine is causing the condition.
  • 4 where the evidence is said to favor acceptance.
  • 5 where the evidence is said to favor rejection, including MMR causing autism.
  • 123 where the evidence is said insufficient to evaluate.

The 2003 IOM Review on multiple vaccines said[2]:
“The committee was unable to address the concern that repeated exposure of a susceptible child to multiple immunizations over the developmental period may also produce atypical or non-specific immune or nervous system injury that could lead to severe disability or death (Fisher, 2001). There are no epidemiological studies that address this.”
and:
“the committee concludes that the epidemiological and clinical evidence is inadequate to accept or reject a causal relationship between multiple immunization and an increased risk of allergic disease, particularly asthma.”

  • None of the IOM Safety Reviews[1][2][3][4] addressed the aluminum (for example whether the aluminum is causing autism), or mentioned contaminants, or discussed animal models although they had concluded as just quoted there is generally no epidemiological or clinical data worth preferring.

(2) The Aluminum.
Alum was added to vaccines back in the 1920’s, with no test of parenteral toxicity until recently[5], because it prods the immature immune system out of its normal operating range.[6] Maybe they figured aluminum is common in the environment, but injection bypasses half a dozen evolved sequential filters that normally keep it out of circulatory flow during development. Vaccines put hundreds of times as much aluminum into infants’ blood as they would otherwise get, and in an unnatural form that is hard for the body to remove.[7][8 (cfsec 4.2)][9]. The published empirical results indicate its highly toxic.

Value Frameworks in Cancer Care: A Beginning, Not the Solution

Posted by in category: biotech/medical

It is good to see production costs v. value add return comparisons with drugs as part of an ongoing drive to create drugs cheaper and making them cheaper to patients. However, lets do not sacrifice quality (especially in areas like cancer, MS, etc.) for costs of development/ cost savings. Value of life is priceless.


Defining the value of a drug in relation to its cost and benefit is an emerging theme in cancer care but remains untested.

Gene signature in ovarian cancer predicts survival and offers new drug target

Posted by in category: biotech/medical

A new UK study has identified a gene signature that predicts poor survival from ovarian cancer. The study also identified genes which help the cancer develop resistance to chemotherapy — offering a new route to help tackle the disease.

The study, published in the International Journal of Cancer, examined the role of HOX genes in ovarian cancer resistance and whether a drug known as HXR9 which targets HOX, could help prevent the resistance from developing.

The HOX gene family enables the remarkably rapid cell division seen in growing embryos. Most of these genes are switched off in adults, but previous research has shown that in several cancers, including ovarian cancer, HOX genes are switched back on, helping the cancer cells to proliferate and survive.

ODNI wants help securing biometric systems

Posted by in categories: 3D printing, bioengineering, biotech/medical, privacy

Glad they are doing something on this because my biggest concern on biometrics and systems storing other people’s DNA/ bio information is criminals hacking in and collecting bio information on people and reselling it on the Dark Web. With this type of information; criminals can do many interesting things especially if they have access to a gene editing kit, or 3D printers, etc. We have seen how easy it is to create gene editing kits and selling them on the net for $129 each. And, how 3D printers can replicate synthetic skin, contacts mimicking eye structures, etc. So, criminals can do some amazing things once they have access to anyone’s biometrics information.


A biometric system to verify travelers exiting the country could be in effect as soon as 2018.

Pre and post testing show reversal of memory loss from Alzheimer’s disease in 10 patients

Posted by in categories: biotech/medical, chemistry, employment, health, life extension, neuroscience

Results from quantitative MRI and neuropsychological testing show unprecedented improvements in ten patients with early Alzheimer’s disease (AD) or its precursors following treatment with a programmatic and personalized therapy. Results from an approach dubbed metabolic enhancement for neurodegeneration are now available online in the journal Aging.

The study, which comes jointly from the Buck Institute for Research on Aging and the UCLA Easton Laboratories for Neurodegenerative Disease Research, is the first to objectively show that memory loss in patients can be reversed, and improvement sustained, using a complex, 36-point therapeutic personalized program that involves comprehensive changes in diet, brain stimulation, exercise, optimization of sleep, specific pharmaceuticals and vitamins, and multiple additional steps that affect brain chemistry.

“All of these patients had either well-defined mild cognitive impairment (MCI), subjective cognitive impairment (SCI) or had been diagnosed with AD before beginning the program,” said author Dale Bredesen, MD, a professor at the Buck Institute and professor at the Easton Laboratories for Neurodegenerative Disease Research at UCLA, who noted that patients who had had to discontinue work were able to return to work and those struggling at their jobs were able to improve their performance. “Follow up testing showed some of the patients going from abnormal to normal.”
