Chocolate lovers rejoice: More chocolate means less body fat | Longevity science | Scoop.it

In what may be the best news for chocoholics since scientists at the University of Cambridge found that higher chocolate consumption was associated with a significant reduction in cardiovascular disease, diabetes and stroke, researchers at the University of Granada are reporting that it's also associated with lower levels of total fat deposits – in the bodies of adolescents at least.

Britons invited to post their genomes online for science

The hunt is on for 100,000 British volunteers to post their genetic information online in the name of science as a North American open-access DNA project arrives in Europe.

 

The launch of the Personal Genome Project UK on Thursday offers the public a chance to learn more about their own genetic profiles and contribute to advances in medical science - but it also poses ethical challenges.

 

Unlike other genome-sequencing initiatives, where data is placed behind a firewall, information contributed to the new project will be available to all.

Leading Research Hospital Spins Out a For-Profit Company to Bring Gene Therapy To Market

Leading Research Hospital Spins Out a For-Profit Company to Bring Gene Therapy To Market | Longevity science | Scoop.it

Gene therapy, in which DNA is administered to patients in hopes of triggering a fix for genetic diseases, was one of many potential medical applications for the big, expensive sequencing projects of the 1990s that were breathlessly hyped by doctors and reporters.

 

And yet no gene therapy treatment has yet been approved for general use in the United States and just one has been approved in Europe.

 

But the winds may be shifting for commercial gene therapy. The Children’s Hospital of Philadelphia has placed a $50-million bet on a spinoff company called Spark Therapeutics that will take over the testing, and hopefully marketing, of several treatments developed there.

How nanotechnology can advance regenerative medicine | KurzweilAI

How nanotechnology can advance regenerative medicine | KurzweilAI | Longevity science | Scoop.it

Nanotechnology may provide new strategies for regenerative medicine, including better tools to improve or restore damaged tissues, according to a review paper that summarizes the current state of knowledge on nanotechnology with application to stem cell biology.

 

Researchers have found that the adhesion, growth, and differentiation of stem cells are likely controlled by their surrounding microenvironment, which contains both chemical and physical cues. These cues include the “nanotopography” of the complex extracellular matrix or architecture that forms a network for human tissues.

Pacemaker Okayed in Europe Is One-Tenth the Size of Those Used Now

Pacemaker Okayed in Europe Is One-Tenth the Size of Those Used Now | Longevity science | Scoop.it

In the coming year, it will likely become significantly easier to receive and live with a pacemaker.

 

Developed by Silicon Valley startup Nanostim, a device about the size of a AAA battery, or one-tenth the size of a conventional pacemaker, was recently approved for use in Europe. It is installed through a catheter in the femoral vein in a minimally invasive procedure. Then, for about 10 years it sits inside the ventricle of the heart and delivers its regulatory electrical pulses wirelessly.

Elderly exercisers have fewer broken bones after falls

Older adults who exercise are less likely to fall, but if they do, they're also less likely to get hurt, a new analysis suggests.

 

Researchers found that older adults taking part in fall prevention exercise programs were about 37 percent less likely to be injured during a tumble, compared to non-exercising participants.

Curcumin Eased Alzheimer’s in Animals

Curcumin Eased Alzheimer’s in Animals | Longevity science | Scoop.it

Alzheimer’s disease is characterized by formation of a “plaque” made of inflammation-inducing proteins called beta-amyloid, which also form wiry tangles.

 It remains uncertain whether amyloid plaque and tangles cause or result from the still-mysterious process that leads to Alzheimer’s disease (AD). Drugs and nutrients that inhibit inflammation, oxidation, and formation of amyloid plaque and tangles also reduce AD symptoms.

Hydrogel implant enables light-based communication with cells inside the body | KurzweilAI

Hydrogel implant enables light-based communication with cells inside the body | KurzweilAI | Longevity science | Scoop.it

Researchers at the Wellman Center for Photomedicine at Massachusetts General Hospital have developed a way to deliver a light signal to specific tissues deep within the body for sensing or treatment.

 

The use of light to communicate with cells has previously been restricted by its limited ability to pass through tissues, especially the skin.

 

Called a light-guiding hydrogel, the implant is constructed from a polymer-based scaffolding capable of supporting living cells and contains cells genetically engineered either to carry out a specific activity in response to light or to emit light in response to a particular metabolic signal.

Proteome Database System

Proteome Database System | Longevity science | Scoop.it

The publicly available Proteome Database System for Microbial Research 2D-PAGE has been established at the Max Planck Institute for Infection Biology and serves as a template for a prototype of a European Proteome Database of Pathogenic Bacteria. The database system is centrally administrated, and investigators without specific bioinformatics competence in database construction can submit their data. The system comprises four heterogeneous but interconnected databases: (i) 2D-PAGE database for 2-D gel electrophoresis and mass spectrometry data, (ii) Isotope Coded Affinity Tag (ICAT)-LC/MS database, (iii) FUNC_CLASS database for functional classification of proteins, (iv) DIFF database for presentation of differentially regulated proteins detected by quantitative gel image analysis. The database system is hyperlinked with public databases such as SWISS-PROT; NCBI; PEDANT and KEGG. The current public release (May, 2004) contains proteomic information on 11 microorganisms such as Mycobacterium tuberculosis, Helicobacter pylori, Chlamydophila pneumoniae, Borrelia garinii, Francisella tularensis, Mycoplasma pneumoniae and information on Jurkat T-cells and mouse mammary gland. Proteomic data are presented in 18 two-dimensional gels with 2572 identified protein spots. For 254 of these spots peptide mass fingerprints are available. More than 1000 identified spots of further miroorganisms such asMycobacterium bovis BCG, Salmonella SL-1344, Vibrio cholerae are stored in the internal release of 2D-PAGE which will be publicly accessible after paper submission. The annotated proteome data such as protein name, molecular weight Mr, isoelectric point pI, gene name, ORF, NCBI accession number, identification method, sequence coverage, protein spot number, class (antigen, gastric carcinoma associated antigen etc.) can be retrieved either by clicking on protein spots or by formulating complex queries. Specific data such as pI, Mr-values or codon usage for proteins can be visualized and analyzed on the fly using the statistical software environment R (http://www.r-project.org/) or can be downloaded as spread sheet files. The Proteome Database System for Microbial Research can be accessed from http://www.mpiib-berlin.mpg.de/2D-PAGE.

The End of Antibiotics?

The End of Antibiotics? | Longevity science | Scoop.it

In recent years, the public health community has sounded increasingly louder alarms about the rise of antibiotic-resistant infections, or superbugs. A recent Frontline documentary quoted associate director at the Centers for Disease Control and Prevention Arjun Srinivasan saying that we’ve reached “the end of antibiotics, period.”

 

It made for an attention-grabbing headline, but what Srinivasan meant was we’re at the beginning of the end of antibiotics: people are dying from bacterial infections, and if we don’t make changes, we could see life-threatening infections become the norm instead of the exception.

 

 

Ray and Terry's 's insight:

The implications extends beyond superbugs. Our decreasing ability to suppress a patient's immune system could slow progress in advancing medical technology. Procedures like transplants and chemotherapy cannot be done without the accompaniment of successful antibiotics.

U.S. FDA moves to ban trans fats, citing health risks

U.S. FDA moves to ban trans fats, citing health risks | Longevity science | Scoop.it

The U.S. Food and Drug Administration on Thursday proposed banning artificial trans fat in processed food, a move that was welcomed by public health advocates but which rattled vegetable oil markets and pushed prices down sharply.

 

The FDA said reducing partially hydrogenated oils (PHOs) from the American diet could prevent 7,000 deaths from heart disease each year.

 

If its proposal becomes final, the oils, the primary dietary source of artificial trans fat, would be considered food additives and could not be used in food unless authorized.

Testosterone tied to heart risks among older men

Older men who take testosterone are more likely to have a heart attack or stroke or die over the next few years, new research indicates.

 

The study included men who were in their early 60s, on average. Most of them already had blocked heart arteries, high blood pressure, diabetes and other health problems.

 

So it's unclear what the findings mean for younger, healthier men who take testosterone, researchers said.

Discovery shines a light on potential cure for Alzheimer's and Parkinson's

Discovery shines a light on potential cure for Alzheimer's and Parkinson's | Longevity science | Scoop.it

It is generally believed that aggregations of proteins are responsible for brain disorders such as Alzheimer's, Parkinson's and Creutzfeldt-Jakob disease. However, the difficulty has been in detecting the aggregates responsible and removing them from the brain. Researchers at Chalmers University of Technology in Sweden and Polish Wroclaw University of Technology have found a potential solution using lasers.

 

Alzheimer's, Parkinson's and Creutzfeldt-Jakob disease are thought to be caused by aggregates of amyloid beta protein that start to inhibit proper cellular processes in the brain. Although it is technically possible to cure the diseases by detecting and removing the amyloid protein aggregates using chemicals, these chemicals are highly toxic and harmful to the patient.

‘Intensive' exercise may benefit heart failure patients

Some doctors caution people with heart failure against pushing themselves too hard physically. But a new analysis of past studies suggests heart patients may actually benefit more from relatively intensive exercise.

 

Researchers found people with heart failure had a 23-percent improvement in heart function after taking part in relatively high-intensity exercise programs. That compared to a 7-percent improvement among those in low-intensity programs.

Compound blocks neurodegeneration in mice | KurzweilAI

An orally administered compound that prevents neurodegeneration in mice has been developed by researchers at the Medical Research Council (MRC) Toxicology Unit at the University of Leicester.

 

The team had found previously (Nature) that the build up of misfolded proteins in the brains of mice with prion disease over-activates a natural defense mechanism in cells, which switches off the production of new proteins.

 

This mechanism would normally switch back on again, but in these mice, the continued buildup of misshapen protein keeps the switch turned off. This is the trigger point leading to brain cell death, since the key proteins essential for nerve cell survival stop being made.
