Technology Review, January 6, 2011: A new nanodelivery system is able to sneak cancer treatments past the defenses of drug-resistant tumor cells—offering hope to many cancer patients who benefit little from existing drug treatments. Researchers at the University of Tokyo designed small soapy clusters of molecules, called micelles, to carry drugs into tumor cells and release their cargo inside. The molecules harness the cell's internal transport system to get close to their target—the cell's DNA. Releasing the drug close to a cancer cell's nucleus appears to protect it from the cell's self-defense mechanism. The approach slowed the growth of tumors in mice—even tumors that were completely resistant to the drug when it was administered normally. The work was published yesterday - Nanocarriers Come Through

Trudeau Institute, January 25, 2011: There is an ongoing battle in the “war on terror” that remains mostly unseen to the public -- a race between scientists working to develop a vaccine to protect against plague and the terrorists who seek to use plague as a weapon. “Governments remain concerned that bioweapons of aerosolized Yersinia pestis, the bacteria that causes plague, could kill thousands,” said Stephen Smiley, a leading plague researcher and Trudeau Institute faculty member - New Discovery Could Lead to Vaccines for Plague and Bacterial Pneumonias

Stony Brook University, January 25, 2011: A powerful new painkiller, which was developed on the basis of the research conducted at Stony Brook University and with no apparent side effects or addictive qualities, may now be only a year or two from the consumer market. "This offers a major paradigm shift in the control of pain," declares Dr. Simon Halegoua - New Painkiller with No Apparent Side Effects or Addictive Qualities Near to Market

UT Southwestern Medical Center, January 26, 2011: Type 1 diabetes could be converted to an asymptomatic, non-insulin-dependent disorder by eliminating the actions of a specific hormone, new findings by UT Southwestern Medical Center researchers suggest. These findings in mice show that insulin becomes completely superfluous and its absence does not cause diabetes or any other abnormality when the actions of glucagon are suppressed. Glucagon, a hormone produced by the pancreas, prevents low blood sugar levels in healthy individuals. It causes high blood sugar in people with type 1 diabetes. “We’ve all been brought up to think insulin is the all-powerful hormone without which life is impossible, but that isn’t the case,” said Dr. Roger Unger, professor of internal medicine and senior author of the study. “If diabetes is defined as restoration of glucose homeostasis to normal, then this treatment can perhaps be considered very close to a ‘cure’ ” - UT Southwestern researchers uncover potential 'cure' for type 1 diabetes

American Technion Society, January 26, 2011: Researchers at the Technion-Israel Institute of Technology have discovered a way to reverse the aging process by removing old B lymphocytes from old mice, and forcing the production of young, potent cells to replace them. The findings were reported in the January 2011 issue of the scientific journal "Blood." “As with every aging process in the body, it is generally thought that aging of the immune system – including that of the B cell population – is a progressive process that cannot be stopped and/or reversed,” says lead researcher Prof. Doron Melamed of the Technion’s Rappaport Faculty of Medicine. “But we have succeeded in showing that it is possible to turn back the aging process.” As is the case with the rest of the body, the immune system is weakened with age, a fact reflected by a significant increase in illness among the elderly, and a dramatic decrease in their ability to respond to vaccination - Technion researchers discover way to reverse immune system aging

"IBM kan stå bak et teknologisk gjennombrudd i kampen mot bakterier som er resistente mot antibiotika."

Han og samarbeidsaprtnerne kan ha funnet mikrobiologiens "hellige gral", hvordan man skal knekke resistente bakterier. Senere er målet å ta knekken på virus og andre sykdomsfremkallende organsimer.

...

IBM har i samarbeid med Institute of Bioengineering and Nanotechnology (IBN) i Singapore utviklet en ny type polymer som både sporer opp og ødelegger resistente bakterier slik som MRSA - Meticillinresistente Staphylococcus aureus - uten å ødelegge friskt vev.

Polymeren ødelegger celleveggen til bakterien, og det er fundamentalt forskjellig fra hvordan vanlig antibiotika virker. Det beste er kanskje at mikroorganismene ikke vil kunne utvikle resistens mot slike polymerer.

Nanowerk, July 6, 2011: Researchers at the Johns Hopkins University School of Medicine have developed a technique that delivers gene therapy into human brain cancer cells using nanoparticles that can be freeze-dried and stored for up to three months prior to use. The shelf-stable particles may obviate the need for virus-mediated gene therapy, which has been associated with safety concerns. The report appears in the August issue of Biomaterials - Just add water to these nanoparticles and treat brain cancer

BBC News, July 7, 2011: Surgeons in Sweden have carried out the world's first synthetic organ transplant. Scientists in London created an artificial windpipe which was then coated in stem cells from the patient. Crucially, the technique does not need a donor, and there is no risk of the organ being rejected. The surgeons stress a windpipe can also be made within days. The 36-year-old cancer patient is doing well a month after the operation. Professor Paolo Macchiarini from Italy led the pioneering surgery, which took place at the Karolinska University Hospital - Surgeons carry out first synthetic windpipe transplant

Massachusetts Institute of Technology, August 10, 2011: Most bacterial infections can be treated with antibiotics such as penicillin, discovered decades ago. However, such drugs are useless against viral infections, including influenza, the common cold, and deadly hemorrhagic fevers such as Ebola. Now, in a development that could transform how viral infections are treated, a team of researchers at MIT’s Lincoln Laboratory has designed a drug that can identify cells that have been infected by any type of virus, then kill those cells to terminate the infection. In a paper published July 27 in the journal PLoS One, the researchers tested their drug against 15 viruses, and found it was effective against all of them — including rhinoviruses that cause the common cold, H1N1 influenza, a stomach virus, a polio virus, dengue fever and several other types of hemorrhagic fever - New drug could cure nearly any viral infection

Penn Medicine, August 10, 2011: In a cancer treatment breakthrough 20 years in the making, researchers from the University of Pennsylvania's Abramson Cancer Center and Perelman School of Medicine have shown sustained remissions of up to a year among a small group of advanced chronic lymphocytic leukemia (CLL) patients treated with genetically engineered versions of their own T cells. The protocol, which involves removing patients' cells and modifying them in Penn's vaccine production facility, then infusing the new cells back into the patient's body following chemotherapy, provides a tumor-attack roadmap for the treatment of other cancers including those of the lung and ovaries and myeloma and melanoma. The findings, published simultaneously today in the New England Journal of Medicine and Science Translational Medicine, are the first demonstration of the use of gene transfer therapy to create "serial killer" T cells aimed at cancerous tumors. "Within three weeks, the tumors had been blown away, in a way that was much more violent than we ever expected," said senior author Carl June, MD, director of Translational Research and a professor of Pathology and Laboratory Medicine in the Abramson Cancer Center, who led the work. "It worked much better than we thought it would" - Genetically Modified "Serial Killer" T Cells Obliterate Tumors in Patients with Chronic Lymphocytic Leukemia, Penn Researchers Report

École Polytechnique Fédérale de Lausanne, August 17, 2011: Like far away galaxies, powerful tools are required to bring the minute inner workings of neurons into focus. A team of neurobiologists, psychiatrists, and advanced imaging specialists from Switzerland’s EPLF and CHUV report in The Journal of Neuroscience how Digital Holographic Microscopy (DHM) can now be used to observe neuronal activity in real-time and in three dimensions—with up to 50 times greater resolution than ever before. The application, borrowed from materials science, has immense potential for testing out new drugs to fight neurodegenerative diseases such as Alzheimer’s and Parkinson’s. It has already been commercialized by the EPFL start-up LynceeTec - Holograms Reveal Brain's Inner Workings
