This invention should come in handy for family holidays (where at least one person always manages to forget at least one essential item...).

As the blogger comments, it would seem that some data other than from the scan may have been needed.

Alethia,
Your post should be on SLA or perhaps "A little Friday Humour" might be more appropriate.

Cso1,

I have reposted your stuff on the SLA / Solagran site.

Solagran is doing a lot of work on the Liver and Alzheimer's. Looks like Solagran is years ahead of the Yanks and even has a drug Ropren registered in Russia targeting the liver. Solagran is also actively trying to enter the American market.

Good find. Thanks

This development could do for electric cars what the invention of the electric starter did for internal combustion engine vehicles (?).

http://electriccarsreport.com/2011/03/new-...in-two-minutes/

Given that on very few days do vehicles travel more than 100 km the fact that electric vehicles can only go 100 km or so before they need a recharge is not that bigger a deal imo. But then having to wait a number of hours for the batteries to recharge is a real disincentive. You can go the Better Place idea and have service stations set up all over the place where you can exchange your flat battery for a recharged battery but that still sounds like too much hassle to me. Being able to pull over and plug in for a couple of minutes sounds far more civilised.

As an aside how good an inventor was Charlie Kettering?

"The findings could offer a relatively simple approach for Alzheimer’s prevention and treatment."

"The mice were injected with Gleevec twice a day for seven days; then plasma and brain tissue were collected, and the amount of beta amyloid in the blood and brain was measured. The findings: the drug dramatically reduced beta amyloid not only in the blood, but also in the brain where the drug cannot penetrate"

Scripps Research study points to liver, not brain, as origin of Alzheimer’s plaques
March 4, 2011 by Editor

Unexpected results from a Scripps Research Institute and ModGene, LLC study could completely alter scientists’ ideas about Alzheimer’s disease—pointing to the liver instead of the brain as the source of the “amyloid” that deposits as brain plaques associated with this devastating condition. The findings could offer a relatively simple approach for Alzheimer’s prevention and treatment.

The study was published online today in The Journal of Neuroscience Research.

In the study, the scientists used a mouse model for Alzheimer’s disease to identify genes that influence the amount of amyloid that accumulates in the brain. They found three genes that protected mice from brain amyloid accumulation and deposition. For each gene, lower expression in the liver protected the mouse brain. One of the genes encodes presenilin—a cell membrane protein believed to contribute to the development of human Alzheimer’s.

“This unexpected finding holds promise for the development of new therapies to fight Alzheimer’s,” said Scripps Research Professor Greg Sutcliffe, who led the study. “This could greatly simplify the challenge of developing therapies and prevention.”

An estimated 5.1 million Americans have Alzheimer’s disease, including nearly half of people age 85 and older. By 2050, the number of people age 65 and over with this disease will range from 11 million to 16 million unless science finds a way to prevent or effectively treat it. In addition to the human misery caused by the disease, there is the unfathomable cost. A new report from the Alzheimer’s Association shows that in the absence of disease-modifying treatments, the cumulative costs of care for people with Alzheimer’s from 2010 to 2050 will exceed $20 trillion.

A Genetic Search-and-Find Mission

In trying to help solve the Alzheimer’s puzzle, in the past few years Sutcliffe and his collaborators have focused their research on naturally occurring, inherited differences in neurological disease susceptibility among different mouse strains, creating extensive databases cataloging gene activity in different tissues, as measured by mRNA accumulation. These data offer up maps of trait expression that can be superimposed on maps of disease modifier genes.

As is the case with nearly all scientific discovery, Sutcliffe’s research builds on previous findings. Several years ago, researchers at Case Western Reserve mapped three genes that modify the accumulation of pathological beta amyloid in the brains of a transgenic mouse model of Alzheimer’s disease to large chromosomal regions, each containing hundreds of genes. The Case Western scientists used crosses between the B6 and D2 strains of mice, studying more than 500 progeny.

Using the results from this study, Sutcliffe turned his databases of gene expression to the mouse model of Alzheimer’s, looking for differences in gene expression that correlated with differences in disease susceptibility between the B6 and D2 strains. This intensive work involved writing computer programs that identified each genetic difference that distinguished the B6 and D2 genomes, then running mathematical correlation analysis (known as regression analysis) of each difference. Correlations were made between the genotype differences (B6 or D2) and the amount of mRNA product made from each of the more than 25,000 genes in a particular tissue in the 40 recombinant inbred mouse strains. These correlations were repeated 10 times to cover 10 tissues, the liver being one of them.

“A key aspect of this work was learning how to ask questions of massive data sets to glean information about the identities of heritable modifier genes,” Sutcliffe said. “This was novel and, in a sense, groundbreaking work: we were inventing a new way to identify modifier genes, putting all of these steps together and automating the process. We realized we could learn about how a transgene’s pathogenic effect was being modified without studying the transgenic mice ourselves.”

Looking for a Few Good Candidates

Sutcliffe’s gene hunt offered up good matches, candidates, for each of the three disease modifier genes discovered by the Case Western scientists, and one of these candidates—the mouse gene corresponding to a gene known to predispose humans carrying particular variations of it to develop early-onset Alzheimer’s disease—was of special interest to his team.

“The product of that gene, called Presenilin2, is part of an enzyme complex involved in the generation of pathogenic beta amyloid,” Sutcliffe explained. “Unexpectedly, heritable expression of Presenilin2 was found in the liver but not in the brain. Higher expression of Presenilin2 in the liver correlated with greater accumulation of beta amyloid in the brain and development of Alzheimer’s-like pathology.”

This finding suggested that significant concentrations of beta amyloid might originate in the liver, circulate in the blood, and enter the brain. If true, blocking production of beta amyloid in the liver should protect the brain.

To test this hypothesis, Sutcliffe’s team set up an in vivo experiment using wild-type mice since they would most closely replicate the natural beta amyloid-producing environment. “We reasoned that if brain amyloid was being born in the liver and transported to the brain by the blood, then that should be the case in all mice,” Sutcliffe said, “and one would predict in humans, too.”

The mice were administered imatinib (trade name Gleevec, an FDA-approved cancer drug), a relatively new drug currently approved for treatment of chronic myelogenous leukemia and gastrointestinal tumors. The drug potently reduces the production of beta amyloid in neuroblastoma cells transfected by amyloid precursor protein (APP) and also in cell-free extracts prepared from the transfected cells. Importantly, Gleevec has poor penetration of the blood-brain barrier in both mice and humans.

“This characteristic of the drug is precisely why we chose to use it,” Sutcliffe explained. “Because it doesn’t penetrate the blood-brain barrier, we were able to focus on the production of amyloid outside of the brain and how that production might contribute to amyloid that accumulates in the brain, where it is associated with disease.”

The mice were injected with Gleevec twice a day for seven days; then plasma and brain tissue were collected, and the amount of beta amyloid in the blood and brain was measured. The findings: the drug dramatically reduced beta amyloid not only in the blood, but also in the brain where the drug cannot penetrate. Thus, an appreciable portion of brain amyloid must originate outside of the brain, and imatinib represents a candidate for preventing and treating Alzheimer’s.

As for the future of this research, Sutcliffe says he hopes to find a partner and investors to move the work into clinical trials and new drug development.

It sounds like Tony Windsor is channeling this bloke...

Pretty out-there predictions back in 1964, and even now they are contentious.

Also shows how even when you get the big picture about right you can totally screw up the ramifications: in the last 50 years the broad trend has been for people to move into cities, and as of last year for the first time in history there are more people in the world living in cities than in non-urban areas (apparently).

This one might not be such "a long way off".

The future for many is obesity and diabetes, sad but true. For many including smokers this may mean amputation of a limb due to poor or no circulation in the far end of the vascular system.

Over 1000 limbs are amputated daily world wide.

An Australian surgeon has invented a device that pumps blood to this region and has already saved a number of limbs with patients returning to a much better life than they have been suffering. Saving limbs and precious health dollars.
This device has about 18 months to go in its trials.
A second use has been identified and received CE marking approved as a repeated access catheter.

I think it is appropriate to mention this information here along with in the EOS channel due to the effects on mankind's future this may bring. lmaosmiley.gif

I think asx ticker stock : EOS could benefit most from this sentiment that i believe will be generated in a most positive way for space, mankind and the technology telescopes have proven now to have given humanity. EOS are into many things but do optics, satellites and telescope creation along with space junk removal plans and seem to have a special niche.

The market seems to be big enough for many small specialize companies world wide to work for mankind and humanity in a network, together 'as one' for the benefit, challenge and pure thrill that this industry now is providing.

The Australian government are also now stepping up to the plate and helping out innovative Australian consortium's and space related business's with grants. EOS is in the thick of it and you can read more about the company here

http://www.sharescene.com/index.php?showtopic=2120

- By Stock' link for the forum on EOS and general chatter about all things mentioned.

I think this news should be in 'Breaking News' due to the great possibilities and positivity for all humanity and hope for mankind's future.

I am very happy to report this as it seems to have just came out in the last 24 hours and is hitting the papers now.

=================================================
* Results from satellite observatory
* 140 Earth-like planets already found
* "Planets like Earth are out there"
============================================
SCIENTISTS are celebrating the discovery of more than 700 suspected new planets - including up to 140 similar in size to Earth - in just six weeks of using a powerful new space observatory.

Early results from NASAs Kepler Mission, a small satellite observing deep space, suggested planets like Earth were far more common than previously thought.

Past discoveries suggested most planets outside our solar system were gas giants such as Jupiter and Saturn - but the new evidence tipped the balance in favor of solid worlds.

Astronomers said the discovery meant the chances of eventually finding truly Earth-like planets capable of sustaining life rose sharply.

NASA so far formally announced only five new exoplanets - those outside our solar system - from the mission because its scientists were still analysing Keplers finds to confirm they were actually planets.

The figures suggest our galaxy, the Milky Way (which has more than 100 billion stars) will contain 100 million habitable planets and soon we will be identifying the first of them, Dimitar Sasselov, professor of astronomy at Harvard University and a scientist on the Kepler Mission said.

"There is a lot more work we need to do with this, but the statistical result is loud and clear and it is that planets like our own Earth are out there."
