Research from Queen Mary, University of London suggests that omega-3 fatty acids, which are found in fish oil, have the potential to protect nerves from injury and help them to regenerate. When nerves are damaged because of an accident or injury, patients experience pain, weakness and muscle paralysis which can leave them disabled, and recovery rates are poor.

More than 42 million Americans suffer from high cholesterol, and 63 million more have borderline high cholesterol. Over time, high levels of LDL cholesterol, often called “bad cholesterol,” build up along the walls of arteries and blood vessels, a process called atherosclerosis, which can lead to a high risk of heart disease, stroke and heart attack.

Patients with high blood sugar run an increased risk of dying if they have a heart attack, and diabetics are less likely to survive in-hospital cardiac arrest than non-diabetics, reveals research at the Sahlgrenska Academy, at the University of Gothenburg, Sweden.

The so-called "bad cholesterol" -- low-density lipoprotein commonly called LDL -- may not be so bad after all, shows a Texas A&M University study that casts new light on the cholesterol debate, particularly among adults who exercise.

Commonly used painkillers to treat inflammation are linked to an increased risk of irregular heart rhythm (known as atrial fibrillation or flutter), concludes a new study. The drugs include non-selective non-steroidal anti-inflammatory drugs (NSAIDS) as well as new generation anti-inflammatory drugs, known as selective COX-2 inhibitors.

The Framingham and National Cholesterol Education Program tools, NCEP, do not accurately predict coronary heart disease, according to a study performed at the Yale University School of Medicine in New Haven, CT.

A large study found strong evidence that older people who have age-related macular degeneration (AMD) are at increased risk for coronary heart disease (CHD), although not for stroke. This result adds to mounting evidence that AMD and cardiovascular disease may share some risk factors–smoking, high blood pressure, inflammatory indicators such as...

By tweaking a single gene, scientists have mimicked in sedentary mice the heart-strengthening effects of two weeks of endurance training, according to a report from Dana-Farber Cancer Institute and Beth Israel Deaconess Medical Center (BIDMC). The genetic manipulation spurred the animals' heart muscle cells -- called cardiomyocytes -- to proliferate and grow larger by an amount comparable to normal mice that swam for up to three hours a day, the authors write in the journal Cell.

An international study led by Ohio State University neuroscience researchers describes one of the missing triggers that controls calcium inside cells, a process important for muscle contraction, nerve-cell transmission, insulin release and other essential functions. The research is being posted online April 22 in the journal Nature. The researchers believe the findings will enhance the understanding of how calcium signals are...

New findings from nutrition researchers at Washington University School of Medicine in St. Louis suggest that it's not whether body fat is stored in the belly that affects metabolic risk factors for diabetes, high blood triglycerides and cardiovascular disease, but whether it collects in the liver.

They are the most widely produced fruit in the world and now scientists in Japan have discovered that tomatoes contain a nutrient which could tackle the onset of vascular diseases. The research, published in the journal Molecular Nutrition & Food Research, reveals that an extracted compound, 9-oxo-octadecadienoic, has anti-dyslipidemic affects.

Doctors have warned that people should try to avoid taking dissolving, fizzy paracetamol (acetaminophen) that contains salt, following findings from a large study that...
