A new family of proteins which regulate the human body´s ℠hypoxic response´ to low levels of oxygen has been discovered by scientists at Barts Cancer Institute at Queen Mary, University of London and The University of Nottingham. The discovery has been published in the international journal Nature Cell Biology. It marks a significant step towards understanding the complex processes involved in the hypoxic response which, when it malfunctions, can cause and affect the...

Treating brain tumors with whole brain radiation therapy can damage healthy brain tissue, but a new study in mice reveals that limiting the oxygen supply, or hypoxia, can alleviate some of the cognitive impairment caused by the radiation. The results are reported in the Jan. 18 issue of the online journal PLoS ONE. The researchers, led by William Sonntag of University of Oklahoma, exposed the mice to a clinically relevant regimen of radiation, which caused progressive deterioration of...

Reducing a protein called Siah2 in mice improves mitochondrial response to low oxygen, a condition cells experience when blood flow is restricted during a heart attack Mitochondria are often called cellular "powerhouses" because they convert nutrients into energy. But these tiny structures also help determine cellular lifespan. Scientists at Sanford-Burnham Medical Research Institute (Sanford-Burnham) are now discovering how mitochondria alternate between duplicating and fragmenting and...

Research may have implications for heart disease, stroke and cancer Scientists at the Gladstone Institutes have identified a protein that kick—starts the response to low levels of oxygen, suggesting new lines of research relevant to a variety of potentially fatal disorders associated with diminished oxygen supply, including cancer, heart disease, stroke and other neurological conditions that affect millions of people worldwide. In a paper being published today in Molecular Cell,...

The latest results from an expedition to Mount Everest that looked at the body's response to low oxygen levels suggest that drugs or procedures that promote the body's production of a chemical compound called nitric oxide (NO) could improve the recovery of critically ill patients in intensive care. Oxygen is required by all larger organisms, including humans, to survive. Many critically ill patients suffer from a shortage of oxygen (a condition known as 'hypoxia'), which can be...

The Gulf of Mexico's "dead zone" is predicted to be the largest ever recorded due to extreme flooding of the Mississippi River this spring, according to a team of scientists working through the support of the National Oceanic and Atmospheric Administration (NOAA). The scientists, from the Louisiana Universities Marine Consortium, Louisiana State University and the University of Michigan, based their forecast on Mississippi River nutrient inputs compiled annually by the US Geological Survey...

A new study links the intermittent interruption of breathing that occurs in patients with obstructive sleep apnea (OSA) to enhanced proliferation of melanoma cancer cells and increased tumor growth in mice, according to researchers in Spain. The study also found tumor cells of OSA mouse models tended to contain more dead cells, indicating a more aggressive type of cancer. The results of the study will be presented at the ATS 2011 International Conference in Denver. "To our knowledge, this...

CAMBRIDGE, Mass., April 12, 2011 /PRNewswire/ -- Quanterix Corporation, enabling a new generation of diagnostics based on revolutionary Single Molecule Array (SiMoA(TM)) technology, today announced that significant elevations in blood levels of amyloid beta (Abeta) 42 peptide, a component of the plaques that are a hallmark of Alzheimer's disease, were detected in patients who experienced hypoxia (inadequate supply of oxygen to the brain) following cardiac arrest. The ability of SiMoA to...

When muscles and organs are deprived of an adequate supply of oxygen--a condition called hypoxia--the body's usual responses include increased circulation and a slight drop in blood pressure in the blood vessels serving the affected tissue. However, the blood vessels in the lungs react differently: blood pressure in the lungs rises, often with deleterious effects on the lungs' tissue and the heart. Larissa A. Shimoda, PhD, Associate Professor of Medicine at the Johns Hopkins University School...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED.
