Global Warming 55 Million Years Ago Too, Thanks to Fossil Fuels

...he atmosphere, the methane would have reacted with oxygen to form carbon dioxide, another greenhouse gas. The Florida core is a sort of smoking gun from the seafloor, a spot where the carbon release actually happened, Miriam Katz of Rutgers University Ms. Katz said at the meeting. She and Gerald Dicken...

Dental X-rays of Carotid Artery Cannot Estimate Stroke Risk

...the U.S. It occurs when a blood vessel that brings oxygen and nutrients to the brain bursts or becomes clogged by a blood clot or some other mass. Panoramic radiography is a procedure used in dental practice for detecting dental disease. According to the JADA article authors, a trend toward using panoramic ...

Research Uncovers the Significant Benefits of Remote Monitoring

...al data such as blood pressure, weight and ECG and oxygen details, to their healthcare provider has increased in prevalence over the past years. According to research recently published in The British Medical Journal, remote monitoring for patients with chronic heart failure helped reduce heart failure admi...

Nutrients in Certain Vegetables may Provide Cancer-fighting Benefit

...d of cancer by forming new blood vessels that pass oxygen and nutrients to tumor cells. "Angiogenesis is a major issue in cancer metastases," said Dr. Singh. "Our results provide promising preliminary evidence that constituents of many edible cruciferous vegetables may slow down, or even halt, this proces...

Link Between Brain Protein and Blood Pressure Rise Found

...ts, this can cause inflammation and result in poor oxygen supply to the brain, reported the online edition of BBC News. The future challenge will be to understand the type of inflammation within the vessels in the brain, the researchers said in the latest issue of journal Hypertension. The scientists a...

Sleep Disorder Linked to Heart Failure Patient Deaths

...nt interruptions in breathing deprive the brain of oxygen and activate the sympathetic nervous system, causing increases in blood pressure, heart rate and other disturbances. This, in turn, contributes to the progression of heart failure and mortality. However, as Dr. Bradley pointed out, most heart fail...

Different Approach Needed to Protect Brains of Premature Babies

...imulate injury, researchers deprived the slices of oxygen and glucose for one hour. At all ages, the resulti...to block a glutamate receptor prior to cutting off oxygen and glucose, it reduced injury with one noteworthy exception. "In the three-day-old mouse brain s...

Glucose Causes Death of Brain Cells in Rodents Following Hypoglycemic Coma

...initiated primarily by mitochondria, which process oxygen for energy within cells. The paper appears in the April 2007 issue of the Journal of Clinical Investigation. In their study, the researchers subjected rodents to a model of severe hypoglycemic coma. 'The rats could remain hypoglycemic without evi...

Novel Airway Bypass Treatment Assists Emphysema Sufferers

...or emphysema patients and many become dependent on oxygen therapy. Researchers at the University of Pennsylvania School of Medicine are now studying an investigational treatment for emphysema, an airway bypass procedure. Physicians create new small pathways using a special needle... "There are limited t...

Wine You can Wear

...pery mould that forms on the top of wine vats when oxygen finds its way in. To form the dress, the wet, sludgy cellulose is patted onto an inflatable doll and allowed to partially dry out. Deflate the doll, and the finished dress comes away. "It's the bacteria that are weaving all these fibres together," ...

Obesity can Cause Asthma too

...on in lung volume and an increase in the amount of oxygen used during breathing, but these on its own would not be enough to induce the condition. UK experts agreed there was a link, but said the reasons were still unclear. A spokeswoman for Asthma UK said: "There is long-standing evidence that obesit...

Breast Cancer and Bra Wearing: Possibly Linked

...and would likely lead to anoxia (lower than normal oxygen content), which has been related to fibrosis, which has been linked to increased cancer risk. The logical conclusion is that bras should be used as little as possible, if at all. Researchers say that women evolved under conditions where there wa...

Asthma Incidence Shows a 50 Percent Increase in Fat People

...ume, chest wall restriction and an increase in the oxygen cost of breathing. It also contributes to various other conditions including gastroesophageal reflux and sleep apnea. These difficulties can result in breathlessness (dyspnea) and wheezing, which might be mistaken for asthma by patients and clinician...

Fat Overrides Effects of Vitamin C

...O diffuses rapidly to lipids, where it reacts with oxygen to reform nitrosating species. The presence of lipids therefore overrides the protective effect of vitamin C against the formation of harmful compounds. Source-Eurekalert SM...

British Doctors on Everest Mission Get Bitter Dose

... the 8,848 m peak in 2007 to measure the amount of oxygen in their own blood on the summit as well as test how well their brains, lungs and metabolisms functioned at extreme altitude. Led by CASE director Mike Grocott, the research was intended to find out more about the changes in the human body when i...

MEG Scanners Are Mega Powerful

...scans reveal which brain areas are active and need oxygen from the blood, Simpson said. But it takes a while for oxygen-filled blood to move in the brain. "If a brain area was active for a 10th of a second, the blood-flow response to that area would take a second or two to start," said Simpson. That may...

Gene Test Shown to Measure Heart Function After Transplant

...biopsies, but has now been shown to correlate with oxygen saturation levels, the pressure in the heart before pumping, and the electrical properties of the transplanted heart. These measures are crucial to understanding how well the transplanted heart is functioning. The research was presented, at the Am...

Choking Game, Rage Among US Teens, Evokes Deep Concern

...er than he could react. His brain was deprived of oxygen for more than three minutes. He was clinically dead. He spent three days in a coma followed by a regimen of anti-seizure drugs. Increasingly teenagers are seeing such choking games on Internet sites like YouTube, and playing them in more threate...

Drugs More Effective Than Angioplasty in the Case of Heart-patients

... around clogged arteries to improve blood flow and oxygen to heart muscle. Surgeons use a segment of healthy blood vessel from another part of the body and create a detour, or 'bypass,' around each blocked portion of artery. Patients usually stay in the hospital at least three days; full recovery may take...

Specially Developed Proteins Could Help Resist Ageing

...sing heavy forms of carbon, hydrogen, nitrogen and oxygen could be on the way. The idea has received a mixed reception from scientists in the field. Some point out that deuterium is toxic in moderate quantities, while others said it would be almost impossible to eat the right amount of fortified food to h...
