Stargazers’ research on stars could have an impact on the human body. Ohio State University uranologists are trying to develop a possible new radiotherapy treatment that will help combat cancer. The freshly discovered technology is designated to be harder on cancerous tumors, but softer on healthy tissue. “ As astronomers, we apply basic physics and chemistry to understand what’s happening in stars. We’re very excited to apply the same knowledge to potentially treat cancer, ” senior research scientist Sultana Nahar said. The team of scientist believe that nanoparticles embedded in cancerous tumors will absorb X-rays better at particular frequencies. This will produce electron ejections that will destroy malignant cells. Using X-Ray spectroscopy scientists can predict those energies and which molecules and atoms will work better.

University Hospitals Case Medical Center heart surgeon have revealed new study indicating an expanded risk of cancer with a group of blood pressure medicines known as angiotensin-receptor blockers (ARBs). This type of drugs is applied along millions of patients not alone for high blood pressure but also for coronary failure, cardiovascular risk diminution and diabetic nephropathy. University Hospitals Group lately accomplished a meta-analysis from almost 60,000 patients arbitrarily delegated to take either an ARB or a moderate medicine. Their determinations are released online today at The Lancet Oncology . The Scientists discovered that patients that used ARBs has "significantly increased risk of new cancer" equated to control patients. "We have found the risk of new cancers was increased with these medications by 8-11 percent," alleged Dr. Ilke Sipahi, associate director of coronary failure and organ transplant "Most importantly, risk of lung cancer...

Late cancer breakthroughs indicate that cancer cells genetically reprogram their energy-generating pathways to produce the units they need to develop and multiply, consuming a lot of energy in the process. Potential drugs that immobilize this footpath could provide a new method to handle a range of cancers. “All tumors have to deal with shifting metabolism as they proliferate,” says Vander Heiden, who joined the Koch Institute last fall. “If you can interfere with that, you have a chance to make a difference across many tumor types.” Sugar is a source of energy for the human cells, it does not call for oxygen and produces much less energy. In 2008, Vander Heiden, Cantley and other scientists at Harvard Medical School accounted in the journal Nature that once the cells switch between normal and Warburg metabolism, they start using PKM2 instead of pyruvate kinase M1, the enzyme that every full-grown cells use for glycolysis (the first set of reactions called for to break down gluco...

A team of researchers in California Institute of Technology in Pasadena have produced tiny nanoparticle robots that can move through human blood and into tumours where they deliver a therapy that puts off an crucial cancer gene. The tiny polymer robots are covered with a protein addressed as transferrin that search out a receptor or molecular doorway on numerous different types of tumors. When the nano robots ascertain the cancer cell and get inside, they collapse, expelling minuscule intrusive RNAs or siRNAs that block a gene that constructs a cancer growth protein called ribonucleotide reductase. "In the particle itself, we've built what we call a chemical sensor," Mark Davis, a professor of chemical engineering, who led the study said in a phone interview. In the first phase of this experimental treatment, the team of researchers applied doses of the pointed nanoparticles 4 times across 21 days in a 30-minute intravenous infusion. Tumour samples acquired of...

Cancer is one of the heaviest problems confusing modern medicine. Recently, Researchers have cracked the genetic code for two of the most common cancer types. This is the beginning of a global effort to catalog all the genes that go amiss among the many types of human cancer, the BBC reports. Too much time spent under the sun apparently leads to most of the 30,000 mutations contained within the DNA code for melanoma, or skin cancer. Outside experts told the BBC that no previous study has managed to link specific mutations to their causes. Researchers also discovered more than 23,000 errors in the lung cancer DNA code, most of them induced by cigarette smoke exposure. A heavy smoker could get one new mutation, potentially harmless but as well possibly a cancer trigger, for every 15 cigarettes that they smoke. The fresh cancer correspondences could conduct to better blood exams for diagnosing the respective cancers, also as better targeted drugs. Blood tests could even break the ...

 TESTS made recently in Germany have uncovered that men who drink beer could keep down their chances of developing prostate cancer. Experimentations have demonstrated that a compund found in beer blocks a chemical reaction that can conduct to the developing of prostate cancer. This harsh disease is treated with drugs that does the same thing.  "We hope that one day we can demonstrate that xanthohumol prevents prostate cancer development, first in animal models and then in humans, but we are just at the beginning." said one of the scientist involved in the study Xanthohumol is a potent antioxidant, recognised to bear anti-cancer properties. It could also be found in various fruits. In a previous study was proposed that the chemical compound could cut down the chances of females getting breast cancer. via

Scientists  have determined fresh proof that it is conceivable for a mother with malignant neoplastic disease to transfer the disease on to her unborn baby. A case study establishes that cancer cells in an baby genetically correspond those from her mom; same mom that  was diagnosed with cancer of the blood briefly after a regular full-term birth. Scientists enunciate uncommon examples of mothers' cancerous cells in babies have been accounted across the last 100 years, which has indicated the hypothesis that malignant neoplastic disease cells possibly transfered from mother to baby. Merely so far it hadn't been sustained genetically. The study , brought out in the Proceedings of the National Academy of Sciences, scientists applied genetical tracking to establish that the malignant neoplastic disease cells were carried from mom to infant. The female parent was a 28-year-old woman who was discovered with leukaemia short after delivering; her 11-month-old girl developed...

A laboratory in Russia says it has built a proton accelerator for treating cancer victims that is 10 times cheaper then any similar device. It may provide salvation for millions of oncology patients around the world. This is great news for all of us! Proton therapy has the best success rate: 90 percent compared to about 40 to 60 percent for other forms of radiotherapy. It provides more effective treatment than x-rays or electron beams because they have greater energy and can be focused on the affected area (tumor). This occurs due to a process known as the Bragg Peak, which causes the protons to land directly on their target, avoiding damage to healthy tissue. The beam slices the DNA in cancerous cells and kills them. So,treating cancer with proton beams is one of the most promising methods to date. The particles are accelerated in a device similar to the famous Large Hadron Collider scaled down to ‘just’ a dozen meters and then fired at a tumour. The beam slices cancerous cells’ DNA a...

 There is a  fluorescent compound attached to live cancer cells that enables scientists to determine either the growth or containment of the disease. A team of scientists from Japan and the United States monitored during this study the spread of breast and ovarian cancer cells in living mice. For this procedure they used a small camera known as an endoscope. The japanese team continued to use Roche AG's Zenapax (another cancer drug) and an endoscope to obtain images of ovarian cancer tumours that had spread inside the abdominal cavities of the living mice. According to the study, which was reported in the British journal Nature Medicine after half an hour after the cancer cells were killed, the substance stopped glowing.  Dr Yobayashi said: "Our design concept is very versatile and can be used to detect many types of cancer. This is very great news in research for cancer cure. via  telegraph.co.uk

Scientists in Australia have discovered antibodies in the blood of sharks that could potentially prove effective in battling cancer. It has been discovered that the antibodies (molecules that fight disease) in sharks are extremely resilient and researchers hope that this quality can be isolated to help slow the spread of cancer, malaria, and other human diseases. The Australian team discovered that shark antibodies were tough and able to survive in both very acidic and very alkaline settings. This is important as it means that a “shark pill” would still be effective within the very acidic environment of the human stomach. The team found that the shark molecules can actually latch on to cancer molecules and stop them from spreading. Associate Prof Mick Foley from Melbourne’s La Trobe University said: “The cells actually grow less than where we don’t add a shark antibody or we add a completely irrelevant shark antibody. So this indicates the shark antibody that we have is binding to ...
