Study shows how individual cells behave during blood vessel formation

Biologists tend to look at cells in bulk, observing them as a group and taking the average behavior as the norm - the assumption is that genetically identical cells all behave the same way.

Study links 13 new gene regions to coronary atherosclerosis

Thirteen new gene regions have been convincingly linked to coronary atherosclerosis in a massive, new, international genetics study involving investigators from the Stanford University School of Medicine.

Monthly liver enzyme tests not required for PAH patients taking Letairis tablets: FDA

The U.S. Food and Drug Administration today announced that monthly liver enzyme tests are no longer required for those taking Letairis tablets (ambrisentan), used to treat high blood pressure in the vessels that carry blood to the lungs (pulmonary arterial hypertension, or PAH).

Executioner enzyme may short circuit second form of cell death

An enzyme viewed as an executioner, because it can push cells to commit suicide, may actually short circuit a second form of cell death, researchers at Emory University School of Medicine have discovered.

Genetic switch increases blood vessels in skeletal muscle of non-exercising mice

Many people suffer from a devastating condition known as critical limb ischemia (CLI) that can lead to muscle wasting and even amputation. The disease is linked to the blockage of blood flow to the skeletal muscle and current treatment options include rehabilitative exercise and surgical bypass of blood vessels. New preclinical research suggests there may be a way to restore blood supply in skeletal muscle without traditional intervention.

New cell therapy can reverse effect of 'bad' LDL cholesterol and reduce atherosclerosis

Researchers at the Swedish medical university Karolinska Institutet have shown in a new study on mice, that cell therapy can be used to reverse the effect of 'bad' LDL cholesterol and reduce the inflammation that leads to atherosclerosis.

New nasal vaccine holds promise against both Alzheimer's disease and stroke

One in eight Americans will fall prey to Alzheimer's disease at some point in their life, current statistics say. Because Alzheimer's is associated with vascular damage in the brain, many of them will succumb through a painful and potentially fatal stroke.

PAH closely related to bone marrow abnormalities

Results from a study published in Blood, the Journal of the American Society of Hematology reveal a close relationship between pulmonary arterial hypertension (PAH)-exceedingly high blood pressure in the arteries carrying blood from the heart to the lungs-and abnormalities of the blood-forming cells in the bone marrow (known as myeloid abnormalities).

Takeda receives FDA approval for EDARBI to treat hypertension in adults

Takeda Pharmaceutical Company Limited and its wholly-owned subsidiary, Takeda Pharmaceuticals North America, Inc., today announced that the U.S. Food and Drug Administration approved EDARBI for the treatment of hypertension, or high blood pressure, in adults.

Researchers capture complexities of breast cancer tumours to improve treatment, diagnostics

Breast cancer can develop very differently in different women. Researchers in Norway are improving breast cancer diagnostics and treatment by identifying the various tumour types. The objective is to find out as much as possible about the various tumour types so that each patient can receive precisely the right treatment at the right time.

Zoledronic acid demonstrates anti-angiogenic effects in metastatic lung cancer

A drug that is currently used to help treat bone metastases in patients with lung cancer could also be useful at an earlier stage of treatment, to prevent the cancer from spreading in the first place, Italian researchers have found.

Omega-3 fish oils: Natural health solution for the heart

Did you know that over the average life span, a heart beats 2 to 3 billion times? As one of the hardest working muscles pumping oxygen and essential nutrients throughout your body an average of 100,000 times a day, the heart needs a lot of help to stay working fit.

Feasibility study to test scalp cooling device in breast cancer patients undergoing chemotherapy

A feasibility study to test the use of a scalp cooling device that breast cancer patients will wear while undergoing chemotherapy treatment will be conducted at Wake Forest University Baptist Medical Center. This will be part of the first significant study of the medical device in the United States.

Women who suffer from menopausal symptoms may face lower risk of cardiovascular events

You are enjoying a night out with friends when it starts; first you feel flush, then a sensation of warmth crawls down your body. Soon you begin perspiring and you feel as if everyone around you can tell what is happening – another hot flash.

Research: Gene mutation linked to schizophrenia may aid in new drug development

In a major advance for schizophrenia research, an international team of scientists led by the University of California, San Diego School of Medicine and involving Trinity College Dublin researchers has identified a gene mutation strongly linked to schizophrenia that may be an important new target for the development of drug therapies.

Progeria-derived iPS cells may treat aging-related disease in children

The current pace of population aging is without parallel in human history but surprisingly little is known about the human aging process, because lifespans of eight decades or more make it difficult to study. Now, researchers at the Salk Institute for Biological Studies have replicated premature aging in the lab, allowing them to study aging-related disease in a dish.

Dual lab tests accurately predict vein graft blood clots in patients during CABG

A team of heart experts at Johns Hopkins has found that dual lab tests of blood clotting factors accurately predict the patients whose blood vessels, in particular veins implanted to restore blood flow to the heart during coronary artery bypass grafting, are more likely to fail or become clogged within six months.

Cerasome filled molecular-sized bubbles to target liver cancer cells

Nanotechnology may open a new door on the treatment of liver cancer, according to a team of Penn State College of Medicine researchers. They used molecular-sized bubbles filled with chemotherapy drugs to prevent cell growth and initiate cell death in test tubes and mice.
