Oxidative Stress News and Research

RSS

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

Exposure to diesel exhaust may exacerbate respiratory diseases

Researchers in the UK have, for the first time, shown how exhaust pollution from diesel engines is able to affect nerves within the lung. Air pollution is a significant threat to health, they say, and identifying potential mechanisms linking exposure to diesel exhaust and the exacerbation of respiratory diseases may lead to treatments for those affected.

Feast-or-famine diet may extend lifespan, improve age-related diseases

University of Florida Health researchers have found that putting people on a feast-or-famine diet may mimic some of the benefits of fasting, and that adding antioxidant supplements may counteract those benefits.

New plant-derived agent protects skin from harmful effects of UV irradiation

The skin is constantly challenged, and very often harmed, by environmental stressors such as UV radiation and chemicals. To cope with UV radiation, various skin cells have evolved a complex protective antioxidant defense system.

First human clinical study of ChromaDex's NIAGEN nicotinamide riboside meets primary endpoint

ChromaDex Corp. announced today that the initial results of the first human clinical study for the company's NIAGEN nicotinamide riboside (NR) has met its primary endpoint.

Combination of coconut oil and exercise training can reduce blood pressure

Coconut oil is one of the few foods that can be classified as a "superfood." Its unique combination of fatty acids can have profound positive effects on health, including fat loss, better brain function and many other remarkable benefits.

New research provides hope for treating stroke using HUCBCs

Researchers have known that transplanted human umbilical cord cells (HUCBCs) can have a restorative effect on the brain and brain function following a stroke. However, just how the cells exert their therapeutic effects has not been clear. Now, a research team from the University of South Florida using animal models of stroke has found that the HUCBCs are most beneficial in preventing neuron loss when the Akt signaling pathway is activated by secretions from the HUCBCs and that Akt activation subsequently impacts a specific gene involved in reducing inflammation.

Fungal infections rarely develop resistance to combination drug therapy

Researchers at the University of Toronto have discovered that Candida albicans -- a leading cause of potentially fatal hospital-acquired infections -- rarely develops resistance to combination drug therapy and, when it becomes resistant, it also becomes less dangerous.

Cooking foods at high temperatures increases Alzheimer's risk

Our new paper published in the Journal of Alzheimer's Disease provides evidence that cooking foods at high temperatures increases the risk of Alzheimer's disease. This study looked at the content of advanced glycation end products (AGEs) in national diets and clinical studies comparing and compared total AGEs to Alzheimer's disease rates.

Research shows olfactory proxy detection is a phenomenon in both insects and humans

Antioxidants are natural food ingredients that protect cells from harmful influences. Their main task is to neutralize so-called "free radicals" which are produced in the process of oxidation and which are responsible for cell degeneration.

Study: Green tea compound may activate a cycle that kills oral cancer cells

A compound found in green tea may trigger a cycle that kills oral cancer cells while leaving healthy cells alone, according to Penn State food scientists. The research could lead to treatments for oral cancer, as well as other types of cancer.

Scientists identify critical molecule that helps explain why diabetics suffer from non-healing wound

One of the most troubling complications of diabetes is its effect on wound healing. Roughly 15 percent of diabetics will suffer from a non-healing wound in their lifetime. In some cases, these open ulcers on the skin lead to amputations.

TSRI scientists find drug candidates that can prevent degeneration of brain cells in Parkinson's

In a pair of related studies, scientists from the Florida campus of The Scripps Research Institute have shown their drug candidates can target biological pathways involved in the destruction of brain cells in Parkinson's disease.

Purdue University researchers find promising way to treat late-stage prostate cancer

Low doses of metformin, a widely used diabetes medication, and a gene inhibitor known as BI2536 can successfully halt the growth of late-stage prostate cancer tumors, a Purdue University study finds.

Genes that increase longevity may not increase healthy lifespan

A study of long-lived mutant C. elegans by scientists at the University of Massachusetts Medical School shows that the genetically altered worms spend a greater portion of their life in a frail state and exhibit less activity as they age then typical nematodes.

Daily use of Pycnogenol may help improve overall cognitive function

New research delivers exciting news for those seeking natural ways to boost memory and mental performance. A study recently published in the Journal of Neurosurgical Sciences shows daily use of Pycnogenol (pic-noj-en-all), a natural plant extract from French maritime pine tree bark, may help improve attention span, memory, decision-making – including executive-level performance – and overall cognitive function.

Iron accumulation in human tissues may contribute to the aging process

It's been known for decades that some metals, including iron, accumulate in human tissues during aging and that toxic levels of iron have been linked to neurologic diseases, such as Parkinson's. Common belief has held that iron accumulation happens as a result of the aging process.

Research findings may lead to new treatment for hypothyroidism

An international research team led by physician-scientists at Rush University Medical Center have gained new insights into hypothyroidism - a condition affecting about 10 million people in the U.S. - that may lead to new treatment protocols for the disease, particularly among the approximately 15 percent of patients for whom standard treatments are less effective.

Exposure to nanoparticles can play major role in development of cardiovascular diseases

Nanoparticles, extremely tiny particles measured in billionths of a meter, are increasingly everywhere, and especially in biomedical products. Their toxicity has been researched in general terms, but now a team of Israeli scientists has for the first time found that exposure nanoparticles (NPs) of silicon dioxide (SiO2) can play a major role in the development of cardiovascular diseases when the NP cross tissue and cellular barriers and also find their way into the circulatory system.

Brazilian researchers find that nutrition education may help prevent reoccurrence of breast cancer

Breast cancer is the most frequent cause of death among women worldwide, and five-year survival rates are just 58.4% in Brazil, lower than in many other regions. In a new study, however, researchers from Federal University of Santa Catarina provided Brazilian breast cancer patients with nutrition education and found it could benefit patients and may help prevent reoccurrence of the cancer.

Researchers examining new antioxidant-based therapeutic approaches to hypertension

High blood pressure affects more than 70 million Americans and is a major risk factor for stroke, heart failure and other renal and cardiovascular diseases. Two University of Houston College of Pharmacy researchers are examining the role of intrinsic antioxidant pathways in mitigating hypertension.
