Discovery sheds light on how forces outside of cells get translated into internal signals

Johns Hopkins researchers used suction to learn that individual "molecular muscles" within cells respond to different types of force, a finding that may explain how cells "feel" the environment and appropriately adapt their shapes and activities.

Researchers identify C. perfringens type B bacteria believed to trigger multiple sclerosis

A research team from Weill Cornell Medical College and The Rockefeller University has identified a bacterium it believes may trigger multiple sclerosis, a chronic, debilitating disorder that damages myelin forming cells in the brain and spinal cord.

Researchers develop new tool to quantify myocardial damage in heart attack patients

Researchers from the Computer Vision Center (CVC) have developed a new tool to quantify the myocardial perfusion damage in people who had a heart attack or an angina. Having been validated in 200 patients, it can help improve and speed up diagnosis of the damage, offering a quantitative, repeatable and objective measure of the blood irrigation level of the heart tissue.

Sleep deprivation may have vascular consequences

Sleep deprivation enlarges the blood vessels and reduces vascular compliance, according to research published in Sleep.

Men who didn't exercise more likely to have dysfunctional HDL

There's no question that high levels of good cholesterol-also known as high-density lipoprotein -seem to be protective against heart disease. Rather than depositing fat into the blood vessels the way the "bad" cholesterol (low-density lipoprotein does, HDL appears to carry cholesterol away from blood vessels to the liver. From there, the liver processes it for removal from the body.

Scientists develop new method to regenerate cartilage

Unlike our bones, the cartilage inside our joints is not vascularized (i.e., it has no blood vessels). This is one reason why cartilage does not heal well after an injury. In athletes in particular, joint injuries often result in cartilage degeneration and arthritis. The process is chronic and irreversible, and to this day, no effective treatment exists.

Combining gene therapy with stem cells leads to faster healing of burns

Johns Hopkins researchers, working with elderly mice, have determined that combining gene therapy with an extra boost of the same stem cells the body already uses to repair itself leads to faster healing of burns and greater blood flow to the site of the wound.

Possible topical treatment for age-related macular degeneration identified by Tufts researchers

Researchers from Tufts University School of Medicine and the Sackler School of Graduate Biomedical Sciences have identified a possible topical treatment for age-related macular degeneration in a study of mice that shows promise for clinical use.

High levels of HDL have been linked to increased breast cancer risks, enhance cancer aggressiveness

High levels of high density lipoprotein (HDL), also known as the "good cholesterol," are thought to protect against heart disease. However, what's good for one disease may not be good for another.

Studies suggest infusion of blood vessel cells may contribute to organ regeneration in future

Damaged or diseased organs may someday be healed with an injection of blood vessel cells, eliminating the need for donated organs and transplants, according to scientists at Weill Cornell Medical College.

Bayer HealthCare receives FDA approval for Adempas tablets

Bayer HealthCare announced today that the United States Food and Drug Administration has approved Adempas (riociguat) tablets for: (i) the treatment of adults with persistent/recurrent chronic thromboembolic pulmonary hypertension (WHO Group 4) after surgical treatment or inoperable CTEPH to improve exercise capacity and WHO functional class; and (ii) the treatment of adults with pulmonary arterial hypertension (WHO Group 1) to improve exercise capacity, improve WHO functional class and delay clinical worsening.

CARUNDA24: A non-invasive continuous blood pressure measurement system

Freienbach, Switzerland: About 1 in 4 people in Switzerland suffer from high blood pressure; worldwide more than 1 billion people are affected increasing the risk of heart attack, cerebral haemorrhage or a stroke. Unfortunately, most affected people don't measure their blood pressure regularly as the measurement method is too complicated and uncomfortable to be part of a daily routine.

High levels of leptin in blood may increase risk of heart attack, stroke

High levels of adipose tissue hormone leptin in the blood reduces blood vessels' ability to dilate, and also affects blood clotting, all of which increase the risk of heart attack and stroke.

Cholesterol-lowering drugs could be alternative treatment for people who take statins

A new class of cholesterol-lowering drugs that target a recently discovered regulator of harmful cholesterol could be an alternative or complementary treatment for the 30 million people who take statins, after the first trial in humans confirms the technique’s feasibility and safety.

New classification criteria for systemic sclerosis published in ACR journal

New classification criteria for systemic sclerosis have just been published and are more sensitive than the 1980 criteria, enabling earlier identification and treatment of this disabling autoimmune disease.

UCSD surgeons perform first robotic gastrectomy for gastric cancer treatment

Surgeons at UC San Diego Health System have performed the region's first robotic gastrectomy, a potentially lifesaving procedure to remove a section of the stomach after a diagnosis of gastric cancer. Aided by a da Vinci robot, surgeons remove the diseased tissue, perform a delicate reconstruction and remove local lymph nodes for further testing.
