Oxidative Stress is a condition in which antioxidant levels are lower than normal. Antioxidant levels are usually measured in blood plasma.

Leukemia itself may increase risk for long-term neurocognitive problems in survivors

Leukemia itself, not just side effects related to its treatment, may increase the risk for long-term problems with attention, organization and related neurocognitive skills in survivors of the most common childhood cancer, according to research from St. Jude Children's Research Hospital. The study appears today in the journal JAMA Oncology.

Single high-fat meal can set the stage for cardiovascular disease

A single high-fat milkshake, with a fat and calorie content similar to some enticing restaurant fare, can quickly transform our healthy red blood cells into small, spiky cells that wreak havoc inside our blood vessels and help set the perfect stage for cardiovascular disease, scientists report.

High levels of humanin protein found in placenta of women who delivered low-birthweight babies

For the first time, UCLA scientists have discovered higher levels of a protein called humanin in the placenta tissue of women who give birth to severely underweight infants.

Johns Hopkins researchers make great strides in understanding biology behind pulmonary hypertension

Working with cells that line the innermost layer of the blood vessels, Johns Hopkins investigators say they have made a leap forward in understanding the underlying biology behind pulmonary hypertension, a dangerous type of high blood pressure in lungs that ultimately leads to right heart failure and death.

Grilled meat could be raising the risk of hypertension finds study

Studies have shown that grilled meat including beef, poultry, fish etc. is usually cooked at high temperatures. This charring can produce cancer causing chemicals. In a new study researchers have found that consuming meat (both white and red) cooked over open flames or at high temperatures can lead to an increased risk of high blood pressure. These results were revealed this week at a meeting of the American Heart Association.

Compound found in beet extract could help slow progression of Alzheimer’s disease

A compound in beets that gives the vegetable its distinctive red color could eventually help slow the accumulation of misfolded proteins in the brain, a process that is associated with Alzheimer's disease. Scientists say this discovery could lead to the development of drugs that could alleviate some of the long-term effects of the disease, the world's leading cause of dementia.

Alzheimer's disease also affects small blood vessels

A research conducted by the UAB demonstrates that mice suffering from this disease also have substantial malfunctions in small blood vessels, important in nourishing different organs and tissues and in regulating blood pressure, and which mainly affects females.

Korean scientists track growth, migration of cells under hypoxic conditions using xCELLigence RTCA

Tracking the growth and migration of cells under hypoxic conditions in vitro can be challenging because measurements must be made in a manner that does not perturb the atmospheric composition of the closed system.

Golgi stress signaling pathway found in cells with Huntington’s disease

Working with cells grown in the lab, Johns Hopkins researchers have identified a biochemical pathway that allows a structure within cells, called the Golgi apparatus, to combat stress caused by free radicals and oxidants.

Individual damaged nerve cells cause neurodegenerative diseases

If the sense of smell disappears, this can indicate a disease such as Alzheimer's or Parkinson's disease. However, unlike previously assumed, general degenerations in the nervous system do not play a leading role in the loss of the sense of smell with increasing age, but individual nerve cells or classes of nerves are decisive.

Preeclampsia during pregnancy contributes to cardiovascular risk factors in women

Women diagnosed with preeclampsia during pregnancy were significantly more likely to develop high blood pressure, diabetes or high cholesterol within five years compared with women who did not have preeclampsia, in a study being presented at the American College of Cardiology's 67th Annual Scientific Session.

Study reveals biological relevance of sex in effects of D-galactose induced aging

A research study by the Universitat Autònoma de Barcelona in collaboration with the University of La Laguna demonstrates in mice the biological relevance of sex in the effects of accelerated ageing caused by a chronic treatment of D-galactose, a sugar found abundantly in milk and to a lesser extent in fruits and vegetables.

Father's age can affect offspring lifespan, mice study shows

How does the father's age at conception affect his children? Researchers at the German Center for Neurodegenerative Disease and fellow scientists have studied this question in mice.

Researchers discover that activation of specific enzyme may help suppress tumor metastasis

To stop the spread of cancer, cancer cells must die. Unfortunately, many types of cancer cells seem to use innate mechanisms that block cancer cell death, therefore allowing the cancer to metastasize.

Potential new principle for treatment of multiple forms of cancer

A study published in Science Translational Medicine shows that small molecules that specifically inhibit an important selenium-containing enzyme may be useful in combating cancer. When researchers at Karolinska Institutet treated cancer in mice using these molecules, they observed rapid tumoricidal effects.

Long-term intake of sunflower, fish oils affects the liver

An international group of scientists led by the University of Granada (UGR) has demonstrated that the long-term intake of sunflower or fish oils damages the liver and can cause a series of alterations in it, giving rise to non-alcoholic steatohepatitis.

Exposure to e-cigarette flavors can cause inflammation to white blood cells, research finds

Sugar and spice are not so nice, at least when it comes to vaping or inhalation. Exposure to e-cigarette flavoring chemicals and liquids can cause significant inflammation to monocytes, a type of white blood cell -- and many flavoring compounds are also toxic, with cinnamon, vanilla and buttery flavors among the worst.

Persistent immune activation may contribute to increased risk of CVD in people with HIV

A review of more than 80 studies reveals that changes in the immune cells of people with human immunodeficiency virus (HIV) infection may increase their risk of cardiovascular disease (CVD). The review is published in the journal Physiology.
