Light Sciences Oncology announces Phase 2 trial of Aptocine in Benign Prostatic Hyperplasia

Light Sciences Oncology, Inc. (LSO) today announced the treatment of the first patients in a Phase 2 clinical trial of its innovative targeted drug treatment Aptocine(TM) (talaporfin sodium) in Benign Prostatic Hyperplasia (BPH). The Phase 2 trial expands the Aptocine BPH development program on the basis of a Phase 1 study at escalating light doses. In the open-label Phase 2 trial, Aptocine is being tested for safety and efficacy in 40 patients with lower urinary tract symptoms (LUTS) due to BPH. Aptocine is also in two Phase 3 clinical trials for solid tumors in the liver as well as preclinical development for prostate cancer.

Researchers find connection between eye disease and arginase

Elevated levels of the enzyme arginase contribute to vascular eye damage and Medical College of Georgia researchers say therapies to normalize its levels could halt progression of potentially blinding diseases such as diabetic retinopathy.

American Asthma Foundation awards $750,000 to Dr.Charles Zuker

Dr. Charles Zuker, a renowned expert on the nerves that determine taste and smell, has been awarded $750,000 by the American Asthma Foundation (AAF). Dr. Zuker will apply his expertise to asthma by defining the nerves that contract the airways during an asthma attack in order to reduce the severity of these episodes.

Sleep apnea increases chances of dying

Nightly bouts of interrupted, oxygen-deprived sleep from a collapsed airway in the upper neck raises the chances of dying in middle-aged to elderly people by as much as 46 percent in the most severe cases, according to a landmark study on sleep apnea by lung experts at Johns Hopkins and six other U.S. medical centers.

Scientists harness carbon nanomaterials for drug delivery, oxygen sensors

Two nanoscale devices recently reported by University of Pittsburgh researchers in two separate journals harness the potential of carbon nanomaterials to enhance technologies for drug or imaging agent delivery and energy storage systems, in one case, and, in the other, bolster the sensitivity of oxygen sensors essential in confined settings, from mines to spacecrafts.

Scientists grow new blood vessels to combat heart disease

Although open-heart surgery is a frequent treatment for heart disease, it remains extremely dangerous. Now groundbreaking research from Dr. Britta Hardy of Tel Aviv University's Sackler School of Medicine has shown the potential for an injected protein to regrow blood vessels in the human heart ― eliminating the need for risky surgery altogether.

Tiotropium - corticosteroid combination improves lung disease survival

Sufferers of chronic obstructive pulmonary disease have a greater chance of survival when treated with a combination of drugs that includes tiotropium, according to research at the University of Illinois at Chicago.

Assisted ventilation in cardiac arrest rescue may lower chances of survival

Arizona researchers have added another piece to the mounting body of evidence that suggests during resuscitation efforts to treat patients in cardiac arrest, "passive ventilation" significantly increases survival rates, compared to the widely practiced "assisted ventilation."

High-fat diets just as unhealthy in short term as long term

Short-term memory getting worse? Exercise getting harder? Examine your diet. New research published online in The FASEB Journal showed that in less than 10 days of eating a high-fat diet, rats had a decreased ability to exercise and experienced significant short-term memory loss. These results show an important link between what we eat, how we think, and how our bodies perform.

New scientific 'edugame' develops and accelerates learning abilities for students, adults, seniors

Stephane Bergeron, M.D., CEO of Brain Center America (BCA), today announced the launch of NeuroActive LEARNING, a new scientific edugame that develops and accelerates learning abilities, for anyone 11 years of age and older, including high-school and college students, adults and seniors. The doctor-developed computer program hits the market Aug. 11.

Research looks at drop in delivery-related rate of death for infants born at term

During about the last 20 years, the risk of delivery-related death at birth or shortly thereafter for term infants has decreased nearly 40 percent in Scotland, with the largest contributing factor being a decrease in the number of deaths caused by a lack of oxygen for the baby during the childbirth process, according to a study in the August 12 issue of JAMA.

Oxygen treatment may speed memory loss associated with Alzheimer's

A 65-year-old women goes into the hospital for routine hip surgery. Six months later, she develops memory loss and is later diagnosed with Alzheimer's Disease. Just a coincidence? Researchers at the University of South Florida and Vanderbilt University don't think so. They suspect that the culprit precipitating Alzheimer's disease in the elderly women may be a routine administration of high concentrations of oxygen for several hours during, or following, surgery - a hypothesis borne out in a recent animal model study.

New treatment for oxygen-starved newborns

Until now immediate cooling of the newborn infant was the only treatment that could possibly prevent brain damage following oxygen deprivation during delivery. New research findings from the Sahlgrenska Academy at the University of Gothenburg and Sahlgrenska University Hospital, Sweden, in collaboration with Zhengzhou University in China, open up the possibility of a new and effective treatment that can be started as late as two days after birth.

New tool for virtual surgery simulates blood flow - helps plan child's delicate heart surgery

Researchers at the Georgia Institute of Technology, collaborating with pediatric cardiologists and surgeons at The Children's Hospital of Philadelphia, have developed a tool for virtual surgery that allows heart surgeons to view the predicted effects of different surgical approaches. By manipulating three-dimensional cardiac magnetic resonance images of a patient's specific anatomy, physicians can compare how alternative approaches affect blood flow and expected outcomes, and can select the best approach for each patient before entering the operating room.

Aldose reductase inhibition shows promise for asthma

University of Texas Medical Branch at Galveston researchers have found that a single enzyme is apparently critical to most allergen-provoked asthma attacks - and that activity of the enzyme, known as aldose reductase, can be significantly reduced by compounds that have already undergone clinical trials as treatments for complications of diabetes.

High-fat diet affects physical and memory abilities of rats after 9 days

Rats fed a high-fat diet show a stark reduction in their physical endurance and a decline in their cognitive ability after just nine days, a study by Oxford University researchers has shown.

Integrated Medical Systems receives U.S. Army order for "suitcase" intensive care unit

Integrated Medical Systems, Inc., a medical technology systems integrator transforming critical care, announced that it has received a commitment for approximately $3.25 million in funding from the U.S. Army's Medical Research Material Command for acquisition and ongoing development of the company's MedEx 1000(TM) "suitcase" intensive care unit (ICU).

New method for neonatal icus reduces infection and lung distress in preemies

A new method for improving quality of care can reduce hospital-acquired infections and chronic respiratory distress with oxygen dependency in premature infants in neonatal ICUs, according to a new study in CMAJ (Canadian Medical Association Journal).

Oxygen nanosensor could improve tumor imaging

A new material developed at the University of Virginia - an oxygen nanosensor that couples a light-emitting dye with a biopolymer - simplifies the imaging of oxygen-deficient regions of tumors. Such tumors are associated with increased cancer aggressiveness and are particularly difficult to treat.
