Respiratory Problems In 9/11 Rescuers

...workers suffering from irritant-induced asthma and reactive airways dysfunction syndrome (RADS) and in a significant number of these workers it has even affected their ability to work. Dr Banauch said it was impossible to predict whether the dust-exposed workers will continue to experience an accelerated dec...

Sensors placed at home capable of signaling onset of early signs of dementia in elderly

... by ORCATECH are "a critical precursor of changing reactive health care to proactive care for individuals." A more proactive health care approach may be essential to managing the rising cost of health care for aging baby boomers. And "being able to stay at home and maintain independence represents a signifi...

Genes Identified To Protect Heart Muscles

...rom death after exposure to high concentrations of reactive oxygen species (ROS). ROS are a natural by-product of the body's metabolism of oxygen and are known by scientists for their signaling role in cellular activity. The findings revealed that HO-1 exerted these remarkable protective effects by cooperat...

Scientist Optimistic In Breakthrough For Causes Of Neurodegenerative Diseases

... oxygen in the body assume an even more chemically reactive forms. But researchers had never been able to find the exact connection between the processes of oxidation and the neurodegenerative diseases. "We looked at a healthy brain and found nitration of proteins that are implicated in neurodegenerative di...

New Way To Combat Spinal Cord Injury during Aortic Surgery

...erts its effects on the spinal cord via release of reactive oxygen species, damage to cellular components such...verall, diazoxide prevented or lessened release of reactive oxygen species, oxidative DNA damage, and cell death while having no effect on expression of DNA rep...

Gene Variations Raise the Risk of Childhood Cancer Survivors

...es involved in metabolizing anthracyclines and the reactive oxygen molecules that anthracyclines produce. If physicians can better classify gene variations that modify side effects of anticancer drugs, they may be able to better tailor treatment plans to individual patients. Thus, knowledge of a patient’s gen...

Instrument to reveal Information about Ozone Loss

... into their constituent parts, which can be highly reactive with ozone. As the polar spring arrives, sunlight returns and creates chemical reactions in PSCs responsible for converting benign forms of chlorine into highly ozone-reactive radicals that spur ozone depletion. A single molecule of chlorine has th...

Potentially Dangerous levels of Platinum Found in Women with Silicone Gel Breast Implants

...e and the platinum can disperse and take on a more reactive form." Amidst the furore, FDA spokeswoman Susan Cruzan has confirmed that they are debating the article threadbare and reviewing its contents, and it might take a while before anything conclusive comes out....

Artemisinin May Prevent Breast Cancer

...reaction ensues that spawns free radicals – highly reactive chemicals that, when formed inside a cell, attack the cell membrane and other structures, killing the cell. As a part of the study, the researchers administered to rats a single oral dose of a substance known to induce multiple breast tumors. Then...

New anti-aging molecule could be coming up in way

...orks by increasing the cells ability to inactivate reactive oxygen species. The protein has been found to act by activating an enzyme called manganese superoxide dismutase (found in the mitochondria of the cell), which hydrolyses the harmful superoxide to less harmful hydrogen peroxide. Free radicals are ...

Chronic Exposure To Benzene May Result In Dysplasia

...he development of BM dysplasia, and suggest that a reactive inflammatory process may be involved in the suppression of hematopoiesis in persistent BM failure following chronic benzene exposure. These findings further suggest the possibility that markers of immune activation or inflammation may prove useful in...

Protein Carbonyl Level Causes Oxidative Protein Damage In Diabetics

... and Nephrology, Medical Faculty, Akdeniz measured reactive carbonyl derivates (PCO), protein thiol (P-SH), and reduced glutathione (GSH) levels in Type 2 diabetic (DM) and diabetic hemodialysed patients (DHD) and in healthy control participants. It was found that protein carbonyl (PCO) content increased sig...

Aspirin May Protect Against Hyperglycemia With Diabetes

... by ferricytochrome c reduction, the intracellular reactive oxygen species (ROS) were evaluated by fluorimetry, and the levels of protein kinase C (PKC) by Western blot. This study confirms and extends previous reports showing that exposure of endothelial cells to high concentration glucose impairs intracel...

Age-Dependent Alterations Not Specific For Alzheimers Disease

...ects (32%) and in the AD patients (18%). Forearm reactive hyperemia was provoked by 1-min occlusion of the brachial artery, and the vascular reactivity was calculated. This phenomenon also proved to be age-dependent, but the process was not related to AD. Results indicate that the lack of forehead vasomotio...

Novel Strategy To Combat Alzheimer’s Disease

...mine oxidase, amyloid-a, ? protein, metal ions and reactive oxygen species. Nevertheless, due to the potential risks in safety, absorbability and pharmacokinetics of synthetic multipotent agents, natural counterparts seem more promising in the future development. ...

Lipoma Arborescens: A Rare Tumor Of The Knee

...e overlying synovial cells may appear enlarged and reactive with abundant eosinophilic cytoplasm. Medical management with intra-articular injection of radio-active compounds such as Yttrium 90 or steroids may lead to resolution of symptoms in the short to medium term. In the case described above, Yttrium tr...

Acute Toxicity Of Nano-Scale Zinc Powder: Severe Renal Damage And Anemia

Although zinc is an essential metal needed by mammals and commonly found in nutritional supplements, acute, high-d...

Critically Ill Patients More At Risk Of Infection If Glucose Is Present In Their Lung Secretions

...re, had higher levels of an inflammatory marker (C reactive protein), and evidence of inflammation on their chest X rays than those in whom MRSA was not found. This suggests that they were more than just carriers of the bacteria, say the authors. In most cases, the detection of glucose preceded MRSA, suggesti...

Astrocytes Found To Cause Epilepsy

Natural formula for protection against vision loss

...ds we eat and the cigarette one smokes, are highly reactive molecules that bind to and destroy body components. The eyes have been found to be more vulnerable to free radical attacks as a result of their dependence on light to function properly. While light enables vision, paradoxically, it also creates addit...
