Hypoxia News and Research

RSS

Hypoxia is a condition in which there is a decrease in the oxygen supply to a tissue. In cancer treatment, the level of hypoxia in a tumor may help predict the response of the tumor to the treatment.

Old Digitalis-based drugs show promise as a treatment for cancer

Digitalis-based drugs like digoxin have been used for centuries to treat patients with irregular heart rhythms and heart failure and are still in use today.

Cardiovascular system proteins play a role in Alzheimer's

Researchers have found that two proteins which work in tandem in the brain's blood vessels present a double whammy in Alzheimer's disease.

New advance in the treatment of sickle cell anaemia

Sickle cell anaemia is a genetic disease characterised by the sickling of red blood cells in patients suffering from hypoxia (around 100,000 cases in Europe and North America).

Doctors' questions about end-of-life legalities may result in patient pain

When treatment options dwindle or are exhausted, terminally ill-patients often opt for pain management and comfort over life-extending therapies. However, a team of researchers from Wake Forest University Baptist Medical Center, University of Rochester Medical Center and Unity Health System, report that a lack of thorough understanding about the laws governing end-of-life care may be leaving many medical providers with an ethical dilemma and causing some terminally-ill patients considerable, unnecessary pain.

Human papillomavirus helps cervical and head and neck cancers resist treatment and grow and spread

The human papillomavirus (HPV) allows infected cervical and head and neck cancer cells to maintain internal molecular conditions that make the cancers resistant to therapy and more likely to grow and spread, resulting in a poor prognosis for patients, researchers with UCLA's Jonsson Cancer Center found.

Discovery of genetic switch critical for cell survival in Hypoxia

Researchers at the University of California, San Diego School of Medicine have identified a critical metabolic "switch" in fruit flies that helps oxygen-deprived cells survive. "A transcriptional suppressor, called hairy, is crucial for reducing the mismatch between supply and demand of oxygen," said Dan Zhou, first author on the study, published October 17 in the open-access journal PLoS Genetics.

Diffusion Pharmaceuticals initiates phase I/II clinical trial in patients with peripheral arterial disease

Diffusion Pharmaceuticals LLC, a clinical-stage drug-development company commercializing new drugs for the treatment of unmet medical needs, announced today that it has begun to enroll patients in a Phase I/II clinical trial of its lead drug candidate trans sodium crocetinate (TSC).

Study looks at anesthetic desflurane and Alzheimer's

In studies of human brain cells, the widely-used anesthetic desflurane does not contribute to increased production of amyloid-beta protein; however, when combined with low oxygen conditions, it can produce more of this Alzheimer's associated protein.

New breakthrough discovery on TB

Medical scientists from the University of Leicester, together with colleagues from St Georges, University of London, funded principally by the Medical Research Council (MRC) and The Wellcome Trust, have published details of a new breakthrough discovery on TB.

New way to grow blood vessels

Researchers at Dana-Farber Cancer Institute have found a previously unknown molecular pathway in mice that spurs the growth of new blood vessels when body parts are jeopardized by poor circulation.

Adaptive functional evolution of leptin in cold-adaptive pika family

Researchers at the Northwest Institute of Plateau Biology, Chinese Academy of Sciences have put forward the viewpoint for the first time that adaptive functional evolution may occur in the leptin protein of the pika (Ochotona) family, a typical cold-adaptive mammal.
