New study suggests novel ways to treat serous retinal detachment

Wet age-related macular degeneration (AMD) is the leading cause of severe vision loss in older individuals. AMD and other serious chronic eye problems that affect younger individuals result when fluid accumulates abnormally under or within the retina. A new study published in The American Journal of Pathology shows for the first time that the release of substances from mast cells may be a causal factor in this type of eye pathology, and inhibitors of this release may offer new ways to treat serous retinal detachment.

Stanford researchers identify iron-containing microglia in the brains of people with Alzheimer's disease

Examining post-mortem tissue from the brains of people with Alzheimer's disease, Stanford University School of Medicine investigators identified what appear to be iron-containing microglia -- specialized scavenger cells that sometimes become inflammatory -- in a particular part of the hippocampus, a key brain structure whose integrity is critical to memory formation.

TTP’s elastography imaging technology provides vital diagnostic information during surgery

The Technology Partnership plc, a leading UK-based research and product development company, has made major advances in the use of elastography, a medical imaging technique that maps the elastic properties of soft tissue to provide vital diagnostic information during surgery.

New findings point toward potential blood test to detect schizophrenia

High blood levels of a growth factor known to enable new blood vessel development and brain cell protection correlate with a smaller size of brain areas key to complex thought, emotion and behavior in patients with schizophrenia, researchers report in the journal Molecular Psychiatry.

Innovation in anaesthesia: an interview with Matti Lehtonen, GE Healthcare

The spectrum of patients seen today, from pre-term infants to the morbidly obese to the longer living elderly, is wider than ever before and increasingly more challenging with patients often presenting with multiple co-morbidities. This puts a huge strain on healthcare providers who are facing increasing challenges such as cost pressure and staff shortages.

Stopping cocaine use may lower levels of ET-1 protein that plays key role in coronary artery disease

For people who use cocaine, stopping or reducing cocaine use is associated with decreased levels of endothelin-1 (ET-1)--a protein that plays a key role in the development of coronary artery disease, reports a study in the Journal of Addiction Medicine, the official journal of the American Society of Addiction Medicine.

University of Twente scientists take significant step in breast cancer research

Scientists at the research Institute MIRA at the University of Twente have been working for some time on a new technique to detect breast cancer. The technique based on the physical principle of photoacoustics, has been christened PAMmography. It uses short bursts of light that cause ultrasonic waves to be generated in places with high density of blood vessels, such as in the vicinity of malignant tumours.

New surgical method preserves long-term renal function following removal of renal tumours

Renal cell carcinomas are one of the most common types of cancer. In order to preserve its wide range of functions, every effort is made not to remove the entire kidney, but rather just a portion of it. A surgical method that preserves long-term renal function has now been carried out successfully for the first time in the Department of Urology at the MedUni Vienna and Vienna General Hospital.

Study offers new way to suppress growth factors related to cancer cell proliferation

Cancer cells need life-essential molecules to proliferate. These so-called growth factors are activated by ectodomain shedding of precursor proteins on the outside of the plasma membrane, mainly carried out by three human cleavage enzymes. A pharmaceutical blocking of these enzymes could hinder cancer from growing but would also inhibit other life-essential processes.

UB researchers to study dangers that dehydration poses for U.S. Navy divers

Researchers at the University at Buffalo School of Public Health and Health Professions will study the dangers that dehydration presents for U.S. Navy divers, examining diver physiology both during and after underwater activities.

Mitek Sports Medicine introduces two new arthroscopic surgery radiofrequency devices

Mitek Sports Medicine, part of DePuy Synthes Companies of Johnson & Johnson, is introducing two new arthroscopic surgery radiofrequency devices this week at the American Orthopaedic Society for Sports Medicine 2015 Annual Meeting.

Potential molecular link identified between excess fat in the blood and blood vessel recovery in ischemia

The buildup of fat in the blood makes a bad situation worse - it not only raises a person's risk for heart attack or stroke but also impairs the growth of new blood vessels. How excess fat in the blood - a condition known as hyperlipidemia - blocks vessel growth was unclear, but new work by researchers at Temple University School of Medicine shows that a molecule known as caspase-1 plays a central role and that preventing its activity could be the key to building new blood vessels and restoring blood supply to oxygen-starved tissues.

Researchers find way to measure the aging process in young adults

An international research team from the US, UK, Israel and New Zealand has found a way to measure the aging process in young adults -- a younger population than is usually tested in aging studies.

Computer model shows how cancerous tumors manipulate blood-vessel growth for their own benefit

Rice University researchers have built a simulation to show how cancerous tumors manipulate blood-vessel growth for their own benefit.

WSU researcher secures $1.25 million NIH grant to study role of rosiglitazone drug in reversing preeclampsia

Sascha Drewlo, Ph.D., assistant professor of obstetrics and gynecology for the Wayne State University School of Medicine, has secured a $1.25 million grant from the National Heart, Lung and Blood Institute of the National Institutes of Health to study the role of approved drugs to improve placental function.

Omega-3 fish oil supplements can improve cardiovascular health of healthy seniors

Bethesda, Md. (July 6, 2015)—Fish oil is one of the most popular dietary supplements in the U.S. because of the perceived cardiovascular benefits of the omega-3 it contains.

Patients who receive intracranial stents at increased risk of experiencing another stroke

The risk of experiencing another stroke is higher if patients, after dilation of their blood vessels in the brain, receive not only clot-inhibiting drugs, but also have stents inserted. The recently published results of the VISSIT study confirm this conclusion of a rapid report by the German Institute for Quality and Efficiency in Health Care (IQWiG) of October 2014.

Dental pulp stem cell transplants can contribute to peripheral nerve regeneration

Peripheral nerve injuries often are caused by trauma or surgical complications and can result in considerable disabilities. Regeneration of peripheral nerves can be accomplished effectively using autologous (self-donated) nerve grafts, but that procedure may sacrifice a functional nerve and cause loss of sensation in another part of the patient's body.

New portable system can produce life-saving NO from air by means of electrical spark

Treatment with inhaled nitric oxide (NO) has proven to be life saving in newborns, children and adults with several dangerous conditions, but the availability of the treatment has been limited by the size, weight and complexity of equipment needed to administer the gas and the therapy's high price.

New AHA/ASA guidelines recommend stent retrievers to treat strokes in selected patients

New devices called stent retrievers are enabling physicians to benefit selected patients who suffer strokes caused by blood clots. The devices effectively stop strokes in their tracks.
