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.

Cancer Research Technology grants Waypharm option to novel platinum agents

Cancer Research Technology Limited (CRT), the cancer-focused development and commercialisation company, today announce that Waypharm S.A.S (Waypharm) has secured rights to evaluate Thioplatin a novel hypoxia-responsive platinum-based cancer therapy, from CRT.

BACE 1 gene may hold the key to Alzheimer's

Canadian scientists have found a specific gene which they believe may hold the key to the degenerative brain disorder Alzheimer's disease.

Kaposi's sarcoma-associated herpesvirus tricks cells to become tumors

Researchers at the University of Pennsylvania School of Medicine have discovered how the Kaposi's sarcoma-associated herpesvirus (KSHV) subverts a normal cell process in order to promote tumor growth.

Victhom files provisional sleep apnea patent application

Victhom Human Bionics announced that, after a series of pilot animal studies on potential medical indications of its Closed Loop System (the CLS Neuromodulator).

Sildenafil boosts high altitude exercise up to 45% for some cyclists

Sildenafil (Viagra) significantly improved the cardiovascular and exercise performance measures of trained cyclists at high altitude, mostly because the drug helped some participants improve a lot -- up to 45% -- while others showed little change. Sildenafil provided no benefit at sea level.

No link between low air-pressure on long-haul flights and DVT

Researchers simulating conditions of reduced cabin pressure and reduced oxygen levels, such as may be encountered during an 8-hour aeroplane flight, found no increase in the activation of the blood clotting system among healthy individuals

DVT and long haul flights - air pressure and oxygen levels not the culprits

According to new research from the UK the reduced air pressure and oxygen levels experienced by travellers on long flights are not responsible for the formation of deadly blood clots often referred to as "economy class syndrome".

Fat cells surrounding coronary arteries may play a role in development of heart disease

The fat cells that surround coronary arteries may play a central and previously unrecognized role in development of cardiovascular disease, according to a study by University of Iowa researchers.

Caudal raphe or the hypoglossal nucleus or both together play roles in sleep apnea

The neural pathways between two areas of the brain that control the tongue -- and their interactions with each other -- may hold the key as to why men suffer sleep apnea much more than women.

Moderate alcohol intake stimulates tumor angiogenesis and expression of vascular endothelial growth factor in a mouse model

University of Mississippi researchers say they have created the first-ever mammalian model of how alcohol consumption spurs tumor growth, showing that even moderate drinking resulted in larger and more robust tumors.

Disturbance of serotonin can lead to sudden infant death syndrome

University of Chicago researchers and colleagues have found strong support that a disturbance of a specific neurochemical can lead to sudden infant death syndrome, the primary cause of death before age 1 in the United States.

Genetic switch that turns off an oxygen-poor cell's combustion engine - finding has potential to limit toxic molecules

Johns Hopkins researchers have discovered a previously unrecognized role played by the gene HIF-1 as it helps cell survive when a lack of oxygen decreases production of an energy-rich molecule called ATP and increases production of toxic molecules.

Metabolic switch required for cellular adaptation to hypoxia

Two new studies in the March Cell Metabolism reveal a survival mechanism by which cells adapt to oxygen starvation by ratcheting down their demand.

Botox finds a use in cancer treatment

The cosmetic treatment Botox may have a new use as an adjuvant to cancer therapy, providing an open door for chemotherapy and radiation treatments, according to a study published in the Feb. 15 issue of Clinical Cancer Research.

New sensor to provide early warning of oxygen loss to unborn children

Researchers at the University of Warwick, and the University Hospitals Coventry and Warwickshire NHS Trust, have devised a new sensor which dramatically improves the amount of early warning doctors and midwives get of a dangerous situation in the birth process when the unborn child's brain is starved of oxygen - Fetal Hypoxia.

Phase II clinical trial for new gene transfer drug study

As many as 8-10 million Americans have Peripheral Artery Disease (PAD), by age 70, roughly 20 percent of the population has it, and people with PAD face a six-to-seven times higher risk of heart attack or stroke.

RPL26 and nucleolin play critical roles in controlling the production of p53

Investigators at St. Jude Children's Research Hospital have discovered a previously unrecognized mechanism that controls a key protein linked to the cell's response to stress - a finding that holds promise for new ways to enhance cancer therapies or protect cells from dying after exposure to damaging chemicals or radiation.

High blood glucose levels early in pregnancy deprive the embryo of oxygen

The babies of women with diabetes are two to five times more likely to develop birth defects than offspring of women without the disease.

Lack of oxygen in body tissues creates a defect of red blood cells that further exacerbates the condition by constricting blood vessels in the lung

What's more, the team demonstrated through studies in people and animals that inhalation of a 'souped up' form of nitric oxide, which targets red blood cells, reverses the blood abnormality to restore normal lung pressure.

New findings suggest balancing Chk1 activity will produce less toxic cancer drugs

A study published by The Burnham Institute in the September edition of Molecular Cell reports that a cell-cycle checkpoint protein, known to be activated by an important class of anticancer drugs, may play crucial roles in both the hampering of therapeutic actions and aiding cancer cells to "recover" and start dividing again after treatment with these drugs.
