Study suggests potential means of stalling or even reversing diabetes-related blindness

Johns Hopkins researchers have discovered a cell signaling pathway in mice that triggers vision loss in patients with diabetic retinopathy and retinal vein occlusion – diseases characterized by the closure of blood vessels in the retina, leading to blindness.

Advanced live cell imaging reveals brain’s response to blood vessel injury

Live cell imaging and laser beam ablation reveals the damage response of pericytes surrounding blood vessels in the brain.

Researchers develop novel organ-on-a-chip device that models atherosclerosis

When studying diseases or testing potential drug therapies, researchers usually turn to cultured cells on Petri dishes or experiments with lab animals, but recently, researchers have been developing a different approach: small, organ-on-a-chip devices that mimic the functions of human organs, serving as potentially cheaper and more effective tools.

FDA gives marketing approval for first shock wave device to treat diabetic foot ulcers

Today, the U.S. Food and Drug Administration permitted the marketing of the Dermapace System, the first shock wave device intended to treat diabetic foot ulcers.

Care suffers as more nursing homes feed money into corporate webs

When one of Martha Jane Pierce's sons peeled back the white sock that had been covering his 82-year-old mother's right foot for a month, he discovered rotting flesh.

Reduced activity of transcription factor plays key role in triggering pulmonary fibrosis

To date, the molecular basis of pulmonary fibrosis has been poorly understood. Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim have now shown that reduced activity of the transcription factor FoxO3 plays a key role in the development of the disease.

Study opens up new avenues for stopping calcific aortic valve disease

The diminutive size of our aortic valve -- just shy of a quarter -- belies its essential role in pushing oxygen-rich blood from the heart into the aorta, our body's largest vessel, and from there to all other organs. Yet for decades, researchers have focused less on damaged valves than on atherosclerosis, the gradual hardening of the blood vessels themselves.

Stress may have greater effect on cardiovascular health in women than in men

New research published in Arteriosclerosis, Thrombosis and Vascular Biology Indicates that mental stress has a greater effect on peripheral vessels in women than in men. The additional constriction of blood vessels seen in women may increase their risk of heart-related events and death.

New retinal imaging scanner may one day revolutionize eye care

SFU engineering science professor Marinko Sarunic has developed a high resolution retinal imaging scanner that will one day revolutionize eye care, helping ophthalmologists diagnose eye diseases before vision loss occurs.

Tumor growth traits can influence response to cancer drugs, study finds

Individual tumors respond differently to cancer drugs, if at all. Until now, it remained a mystery why tumors have different reactions to the exact same therapy. But a new study at the USC Viterbi School of Engineering finds that tumor growth properties can influence response to cancer drugs.

Constriction of blood vessels during mental stress more likely to affect women

In women with heart disease, constriction of peripheral vessels during mental stress affects the heart circulation more than men's, potentially raising women's risk of heart-related events and death, according to new research in Arteriosclerosis, Thrombosis and Vascular Biology, an American Heart Association journal.

Alcohol related hangovers may soon be passé with the advent of “safer” alternatives

Professor David Nutt, previously chairman of the United Kingdom’s Advisory Council on the Misuse of Drugs and now teaching at Imperial College, believes that having a hangover after a an episode of binge drinking would soon be a thing of the past. A new synthetic alcohol called “alcosynth” could provide the pleasures of alcohol consumption without the harmful side effects.

Immune system plays key role in development of atherosclerosis

The immune system plays an important role in the development of atherosclerosis, the underlying cause of cardiovascular diseases. Thomas van der Heijden has discovered that immunosuppressants may play a preventative role. PhD defense 19 December.

Nano-encapsulation of bilirubin could enhance survival rates of pancreatic islet cells

By encapsulating bilirubin within tiny nanoparticles, researchers from North Carolina State University and the Ohio State University have improved the survival rates of pancreatic islet cells in vitro in a low-oxygen environment.

Children who experience abuse, adversity more likely to develop cardiovascular diseases in adulthood

Children and teens who are abused, witness violence, are bullied or face other adversities are more likely to develop cardiovascular diseases in adulthood, according to a new scientific statement by the American Heart Association published in the Association's journal Circulation.

Excessive copper in diabetes impedes ability to make new blood vessels

It's a metal we worry thieves will steal from our air conditioners or power lines, but inside our bodies too much copper can result in a much larger loss.

Study finds erectile dysfunction as risk factor for early cardiovascular disease

Despite decades-long prevention and treatment efforts, cardiovascular (CV) disease continues to be the leading cause of death worldwide.

Extracellular vesicles can be used to effectively delay progression of kidney damage

Researchers have demonstrated for the first time that extracellular vesicles - tiny protein-filled structures - isolated from amniotic fluid stem cells (AFSCs) can be used to effectively slow the progression of kidney damage in mice with a type of chronic kidney disease.

Mosquito-infected monkeys may provide better understanding of Zika transmission routes

Monkeys who catch Zika virus through bites from infected mosquitoes develop infections that look like human Zika cases, and may help researchers understand the many ways Zika can be transmitted.

Retinal diseases could be treated by ophthalmic drops instead of intraocular injections

The Spanish firm Sylentis has developed a compound to treat diseases of the retina, such as age-related macular degeneration and diabetic retinopathy, which will be administered by ophthalmic drops instead of intraocular injections.
