    Rutherford-Appleton Laboratories have developed one of the World´s largest imagers that could form the heart of future medical scanners. The new technology will allow doctors to produce more sensitive and faster images of the human body at a lower-cost to the healthcare profession.

    The innovative technology, which has been developed as part of the £4.5m Basic Technology MI-3 Consortium, will help in providing instant analysis of medical screening tests and the early detection of cancer.

    Easier to use and faster than the imagers used in current body scanners, and with very large active pixel sensors with an imaging area of approximately 6cm square, the technology has been specifically developed to meet demanding clinical applications such as x-ray imaging and mammography. This silicon imager is about 15 times larger in area than the latest Intel processors.

    The next step of the project is to produce wafer-scale imagers which can produce images that approach the width of the human torso. This will eliminate the need for expensive and inefficient lenses and so enable lower-cost, more sensitive and faster medical imaging systems. Very large active pixel sensors could soon be making a major impact on medical imaging by further reducing the need for the old technology of film. The UK is a World-lead in such sensors for scientific and medical applications and this is a lead that UK intends to maintain.

    Nutrigenomics is the study of molecular relationships between nutrition and the response of genes. (wikipedia) It focuses on the effects of nutrients to gene development and the overall effect to human health. The aim is to develop a personalized nutrition program based on an individual’s genotype, as certain diseases are caused by changes in the DNA.

    Nutrients are seen by the cells as signals, and the cell’s sensor system interprets this signal. This process then changes gene, protein expression and metabolite production depending on the level of nutrient it senses. Nutrigenomics aims to identify these patterns and effects called dietary signatures.

    This research is still in its early stages, but is a promising field that gives hope for the future.

    If you are suffering from sleep deprivation, produces a cow-like snoring and maintains a compulsion to be sleepy all throughout the day, it’s not normal. Science calls this disorder Sleep Apnea (apnea means “without breath”) wherein the breathing patterns of a person repeatedly halts and starts when one is sleeping. The latest treatment against Sleep Apnea is called TAP or Thornton Adjustable Positioner, a customized oral appliance that the patient wears during sleep. By holding and keeping the lower jaw forward and not allowing the tongue and the throat tissues to collapse to the airway, it prevents snoring and sleep apnea.

    If you know anyone who has experienced Angiography, you know that he will never recount the story of the experience without cringing or deep facial expression expressing pain — both the physical and the financial pain, mind you. And now comes Super X-ray that saves one from the angiogram fatality caused by bacterial invasion and exposure to radiation that may eventually lead to cancer. According to studies, this new product will eliminate the use of some 1.3M cardiac catheterizations per annum. Although there have been debates on the radiation level this new technique can emit, more scientists have favored it for its accuracy.

    In the ever-improving world of neuromedicine, psychology and psychiatry, the newest materializing exploratory pursuit is the Deep Brain Stimulation (DBS) technique that uses implants that hinders tremors experienced by people with Parkinson’s Disease. Forty thousand patients around the world have benefited from these implants. Nowadays, researchers are exploring the possibility of using the same technique in an attempt to cure mental illnesses like obsessive-compulsive disorder and chronic depression as well. They are seeing the possibility of these implants to act like an antidepressant for diseases which have severe untreatable manifestations. These brain pace-makers will surely help a lot of people in setting foot once again to normalcy but authorities emphasize that Deep Brain Stimulation using implants is still on its initial experimental state.

    Great news for hospitals and other clinical facilities with an enormous need of improvements with medical scanners - The University of Sheffield and STFC Rutherford-Appleton Laboratories have provided the world a medical scanner that is easier to use and produces faster and more sensitive images.

    This recent development offers immediate analysis of medical screening tests and early detection of cancer. It can also be of service in x-ray imaging and mammography.

    The developers are looking at wafer-scale imagers, which can generate images with width of the human torso as the next big thing for this project. If this pushes through, it will allow more efficient and productive medical imaging systems.

    It has been discovered recently that the progress of Alzheimer’s in the brain also happens in the eye, which is actually a direct extension of the brain. Amyloid beta proteins, which is found to be a biomarker for the disease, can be detected and measured in the eye even before the disease shows its symptoms. This gives hope that early detection leads to preventive measures and treatment.

    The device developed is an interior laser ophthalmoscope. Since the formation of amyloid beta proteins in the eye resemble a cataract, a special method was devised. The eye is injected with fluorescent drops that react to the amyloid beta proteins, and glows under infrared lights.

    An artificial heart pump specially designed for children with heart failure has been developed. It is much smaller than existing ventricular assist devices (VAD). It can be used even for newborns. It has been named PediPump, and developed by biomedical engineers and doctors at the Cleaveland Clinic. The PediPump efficiently moves blood without damaging too much red blood cells.

    The device has two versions: one has a design similar to conventional VAD, with inflow conduit in the ventricle and outflow conduit at the artery. The second design the pump’s inflow is in the ventricle, and the outflow in the artery.

    Japanese researchers at Osaka University are undergoing research on putting electrode censors to the brain to analyze electrical activity, which can be used to operate mechanical devices. A robotic arm, for example, should be able to move in real time, just as a real human hand moves with just a mind’s thought. The movements will be controlled by sensors that pick up electrical signals from the brain. However, since direct contact with the brain is needed, there is no actual experiment as of the moment. The researchers already filed an application for license with the Osaka University Hospital ethics board.

    Patients with congenital heart disease will have a chance at a treatment without a major open heart surgery. Cardiologists at the Rush University Medical Center has developed a minimally-invasive transcatheter valve replacement. Patients involved in a clinical trial had this implant, and are presently recovering. This gives hope to patients that would otherwise undergo multiple open heart surgeries. The valve replacement procedure uses a bovine pericardial heart valve that is compressed into a balloon as small as a pencil, threaded from a major vein in the leg into the circulatory system, and is deployed across the pulmonary valve.

    The US Food and Drug Administration conditionally approved the trial in 2007.
