29/05/2017Contrary to the condition's name, heart failure does not mean the heart has stopped pumping – it is just not working at full strength. It can often be managed with medications and lifestyle changes, but its progression needs to be monitored closely.
24/05/2017A drop of blood on filter paper, allowed to dry and stored for future diagnostic purposes - considerably easier than the present-day, resource-consuming method using frozen blood samples in plastic tubes. In a new study, Uppsala researchers have successfully measured 92 different proteins in millimetre-sized circles punched out of dried samples.
17/05/2017A team of researchers from Cleveland Clinic, Louis Stokes Cleveland VA Medical Center, Kaiser Permanente Northwest, and other clinical sites have demonstrated that a new blood test known as IsoPSA detects prostate cancer more precisely than current tests in two crucial measures - distinguishing cancer from benign conditions, and identifying patients with high-risk disease.
12/05/2017The fight against skin cancer just got a new weapon. For years, melanoma researchers have studied samples that were considered uniform in size and color, making them easier to examine by more conventional means. But melanomas do not always come in the same shape and hue; often, melanomas are irregular and dark, making them difficult to investigate.
11/05/2017Imagers, gastric pacemakers and other diagnostic and therapeutic tools could someday transform the way diseases of the gastrointestinal tract are measured and treated. But in order for these electronic devices to work, they need a power source. Using mid-field wireless powering, investigators can transfer power from outside the body to electronics in the gastrointestinal tract.
08/05/2017A recent study, affiliated with UNIST has proposed the possibility of in situ human health monitoring simply by wearing a contact lens with built-in wireless smart sensors.
28/04/2017Traditional toxicological investigations performed on animals (in vivo) are expensive, time-consuming and may cause animal suffering. But research from Umeå University demonstrates that a neuronal cell model, derived from mouse, can be used to evaluate the neurotoxic effect of chemicals.
28/04/2017With more than 420 million affected individuals, as highlighted by the WHO Global report on diabetes issued for the 2016 World Diabetes Day, diabetes is among the leading metabolic diseases and a growing burden for health systems across the globe.
27/04/2017In the United States alone, a half million babies are born preterm; worldwide, the number is an estimated 15 million. Complications associated with preterm birth are the no. 1 cause of death for children under 5, and those who live often face a range of health problems.
27/04/2017The structural properties of proteins that could eventually become important materials for manufacturing and medicine are revealed by a novel optical technique that works rapidly to sort through amino acid sequences even inside living bacteria, according to a team of engineers.
20/04/2017Again, this year on April 23rd, the World Laboratory Day is celebrated. It addresses the general public and answers the different questions around the theme laboratory. For that reason, laboratories and laboratory schools worldwide are open for the interested public and allow a look into the world of the laboratory.
19/04/2017A new study by Yusheng Feng, professor of mechanical engineering at The University of Texas at San Antonio (UTSA), describes an algorithm that can predict the growth of cancerous tumors, which could help medical professionals judge the best treatment options for patients.
14/04/2017Most ovarian cancer is diagnosed at such late stages that patients' survival rates are poor. However, if the cancer is detected earlier, five-year survival rates can be greater than 90 percent. Now, MIT engineers have developed a far more sensitive way to reveal ovarian tumors.
13/04/2017Researchers at Children's Hospital of Pittsburgh of UPMC and University of Pittsburgh School of Medicine have developed and refined a blood test that could help clinicians identify infants who may have had bleeding of the brain as a result of abusive head trauma, sometimes referred to as shaken baby syndrome. The science behind the test is described today in "JAMA Pediatrics".
12/04/2017Researchers at the University of Liverpool have identified the basis for how a single gene mutation can cause a rare neurological movement disorder known as dystonia. It can result from an injury or can be an inherited disorder in which patients progressively develop from childhood uncontrollable muscle contractions leading to repetitive movements and awkward and painful postures.
31/03/2017From using fluid in the lungs to better understand the potential of immunotherapy treatments in lung cancer, to tracking circulating tumor cells in prostate cancer, to conducting RNA sequencing of cancer cell clusters from the blood of pancreatic cancer patients, a series of studies from the University of Pennsylvania demonstrate the promise of new diagnostic methods.
30/03/2017A method for diagnosing flu virus from breath samples could soon replace invasive nasal swabs and deliver better results faster. There's a short window for detecting influenza virus, because as the infection takes hold – the concentration of the virus lessens. So if the patient isn't tested soon after exposure, conventional methods run the risk of a giving a false negative result.
27/03/2017A team of engineering and medical researchers has found a way to use ultrasound to monitor fluid levels in the lung, offering a noninvasive way to track progress in treating pulmonary edema - fluid in the lungs - which often occurs in patients with congestive heart failure. The approach, which has been demonstrated in rats, also holds promise for diagnosing scarring, or fibrosis, in the lung.
23/03/2017It is the part of the eye exam everyone hates: the pupil-dilating eye drops. The drops work by opening the pupil and preventing the iris from constricting in response to light and are often used for routine examination and photography of the back of the eye.
09/03/2017Interventional radiologists at the University of California at Los Angeles (UCLA) are using technology found in self-driving cars to power a machine learning application that helps guide patients' interventional radiology care, according to research presented at the Society of Interventional Radiology's 2017 Annual Scientific Meeting.
02/03/2017An approved international test to check whether people need open heart surgery could be sending twice as many people under the knife unnecessarily, at a cost of nearly £75m, research by the University of Leicester has suggested.
