Philadelphia, Pa. – Sound waves are widely used in medical imaging, such as when doctors take an ultrasound of a developing fetus. Now scientists have developed a way to use sound to probe tissue on a much tinier scale. Researchers from the University of Bordeaux in France deployed high-frequency sound waves to test the stiffness and viscosity of the nuclei of individual human cells. The scientists predict that the probe could eventually help answer questions such as how cells adhere to medical implants and why healthy cells turn cancerous. "We have developed a new non-contact, ...

Philadelphia, Pa. – The texture of breast cancer tissue differs from that of healthy tissue. Using a cutting-edge tissue diagnostic device, a group of researchers in Basel, Switzerland, has determined one key difference: cancerous tissue is a mix of stiff and soft zones, whereas healthy tissue has uniform stiffness. This new finding may one day help improve breast cancer diagnosis and therapy by providing a unique nanomechanical signature of tumor tissue properties that indicates the potential for the cancer to spread. The team will present its work at the 57th Annual Meeting ...

Philadelphia, Pa. – A research team in Israel has devised a novel approach to identifying the molecular basis for designing a drug that might one day decrease the risk diabetes patients face of developing Alzheimer's disease. The team will present its work at the 57th Annual Meeting of the Biophysical Society (BPS), held Feb. 2-6, 2013, in Philadelphia, Pa. A recent study suggests that people who suffer from type 2 diabetes face twice the risk of developing Alzheimer's disease later in life compared to those who do not have diabetes. The link these diseases share relates ...

Philadelphia, Pa. – Microbes exhibit bewildering diversity even in relatively tight living quarters. But when a population is a mix of cooperators, microbes that share resources, and cheaters, those that selfishly take yet give nothing back, the natural outcome is perpetual war. A new model by a team of researchers from Princeton University in New Jersey and Ben-Gurion University in Israel reveals that even with never-ending battles, the exploiter and the exploited can survive, but only if they have room to expand and grow. The researchers present their findings at the ...

Philadelphia, Pa. – With the discovery of antibiotics, medicine acquired power on a scale never before possible to protect health, save lives, and reduce suffering caused by certain bacteria. But the power of antibiotics is now under siege because some virulent infections no longer respond to antibiotic drugs. This antibiotic resistance is an urgent public health threat that a team of researchers from Sabanci University in Istanbul, Turkey, and Harvard Medical School and Harvard University in Cambridge, Mass., aim to stop. Their approach is based on an automated device ...

Philadelphia, Pa. – The treatment of central nervous system (CNS) diseases can be particularly challenging because many of the therapeutic agents such as recombinant proteins and gene medicines are not easily transported across the blood-brain barrier (BBB). Focused ultrasound can be used to "open the door" of the blood brain barrier. However, finding a way to "prop the door open" to allow therapeutics to reach diseased tissue without damaging normal brain tissue is the focus of a new study by a team of researchers at the Institute of Biomedical Engineering at National ...

Philadelphia, Pa. – The shortened daylight of a Maine winter may make for long, dark nights – but it has shone a light on a novel experimental approach to fighting inflammatory breast cancer (IBC), an especially deadly form of breast cancer. The new approach enlists the active form of Vitamin D3, called calcitriol, which is delivered therapeutically by quantum dots. Quantum dots are an engineered light-emitting nanoscale delivery vehicle. This new preliminary work shows the dots can be used to rapidly move high concentrations of calcitriol to targeted tumor sites where ...

New Rochelle, NY, January 31, 2012—Powerful antisense drugs that target disease-associated genes to block their expression can be used to treat a broad range of diseases. Though antisense therapy has been proven effective, challenges remain in ensuring that the drugs reach their intended targets. Two new methods for detecting and measuring the levels of antisense drugs in cells that could accelerate the development of improved antisense drugs are described in an article in BioResearch Open Access, a bimonthly peer-reviewed open access journal from Mary Ann Liebert, Inc., ...

PHILADELPHIA — Traumatic injury – including car accidents, gunshot wounds, and stabbings – is the leading cause of death for people younger than 40 years old in the United States, but despite the toll of these injuries, few emergency medical interventions considered to be the standard of care for these injuries have been rigorously studied in clinical trials, because patients and their families are typically unable to consent to participate in research. A new study from the Perelman School of Medicine at the University of Pennsylvania sought to examine peoples' willingness ...

Researchers at Moffitt Cancer Center and colleagues at the Mayo Clinic in Rochester, Minn., have developed a novel computer algorithm to easily quantify a major risk factor for breast cancer based on analysis of a screening mammogram. Increased levels of mammographic breast density have been shown in multiple studies to be correlated with elevated risk of breast cancer, but the approach to quantifying it has been limited to the laboratory setting where measurement requires highly skilled technicians. This new discovery opens the door for translation to the clinic where ...

Disparity in Crack Cocaine and Powder Cocaine Sentencing There is no question that the justice system treats offenses involving crack cocaine and powder cocaine differently. The U.S. Supreme Court states that 100 grams of powder are treated the same as just 1 gram of crack. As a result, an individual arrested with 5 grams of crack could receive drug charges that may include a five-year prison sentence, while someone with the powder version would have to possess at least 500 grams to receive the same sentence. A Bit of Background: Why the Difference? Why the ...
