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.

UH professor examines life cycle of drug-resistant persister cells in recurrent infections

A University of Houston engineering professor is examining the life cycle of stubborn, drug-resistant persister cells in recurrent infections to find a way to destroy them.

Researchers develop first non-invasive way to monitor oxygen in tumors during radiation therapy

Oxygen in cancer tumors is known to be a major factor that helps radiation therapy be successful. Hypoxia, or starvation of oxygen, in solid tumors is also thought to be an important factor in resistance to therapy.

High carbon dioxide levels due to respiratory diseases may aggravate pancreatic cancer

Chronic obstructive pulmonary disease or COPD is associated with higher rates of many cancers, including lung, esophagus, colon, bladder and breast cancer.

Immune system cells facilitate the invasive capacity of glioblastoma

In a study published in Brain Communications, a new Open Access publication of the well-known journal Brain, the team led by Carlos Barcia, researcher at Institut de Neurociències of the Universitat Autònoma de Barcelona, analyzed the role of immune cells in the expansion of glioblastoma, the most aggressive brain tumor.

UT Southwestern study identifies new vulnerability in kidney tumors

A UT Southwestern researcher led a team that identified a new vulnerability in kidney tumors, the 10th most common cause of cancer death in men and women.

New methodologies could help premature babies breathe easy

When a premature baby is born, the immediate challenge is to ensure it breathes easily without outside help. A new study shows that by carefully supplying 100% oxygen to these fragile scraps of humanity, independent breathing can be initiated much faster.

Discovery of novel mechanism by which certain breast cancers can metastasize

Researchers from the Baylor College of Medicine and Harvard Medical School have found a novel mechanism to explain the resistance of certain breast cancers that spread in the major organs of the body. They hope that this would help develop new therapeutic strategies to treat the cancer.

Fetal heart rate could predict future heart health of babies

Changes in heart rate due to low oxygen conditions experienced by the fetus during pregnancy could predict the future heart health of babies, suggests research published today in The Journal of Physiology.

New 5G-based system reduces time of action and errors during emergency situations

5TONIC, the open research and innovation laboratory on 5G technologies, founded by Telefónica and IMDEA Networks, has presented, together with SAMUR-PC and the Carlos III University of Madrid, a new system for situations 5G-based emergency plan, developed under the European innovation project 5G-TRANSFORMER.

Changes in placenta could mean males born to older mothers more prone to heart problems

A new study in rats shows that older mother rats develop poorer placentas which are in turn related to later risk of heart problems in their male offspring. The study, published in the journal Scientific Reports, shows that both male and female offspring are smaller in size when the mother is older. However, the placental development in older mothers with male fetuses is especially impaired, leading to worse placental function. As a result, heart problems are more common in later life in these offspring, as is high blood pressure.

Study on acclimatization and de-acclimatization to take place for simulation of extreme climates

A Eurac Research study on acclimatisation and de-acclimatisation will take place in the terraXcube centre for the simulation of extreme climates. Internationally renowned, especially for his extreme winter climbs, mountaineer Simone Moro, and Tamara Lunger, one of the world's strongest high-altitude climbers, announce the destination of their next expedition.

New method for correcting hypoxic conditions of the central nervous system

Hypoxia is a key factor that accompanies most brain pathologies, including ischemia and neurodegenerative diseases.

Apoptosis protein API-5 more markedly expressed in chemoresistant triple-negative breast cancer

78 TNBC biopsies from patients with different responses to chemotherapy were analysed for API-5 expression before any treatment.

New research project could help reduce unnecessary C-sections in Ireland

A new research project at Trinity College Dublin could have far-reaching implications for the management of labour, making monitoring less intrusive and potentially reducing the number of unnecessary caesarean sections in Ireland.

UK to be transformed into global hub for next-generation radiotherapy research

The UK will be transformed into a global hub for radiotherapy research, pioneering the use of the latest techniques such as FLASH radiotherapy and artificial intelligence, with a new £56 million research network announced by Cancer Research UK today (Monday).

Liposomes cross blood brain barrier, could get healing drugs to stroke-affected brain

A new study from University of Manchester researchers, published in ACS Neuro, shows a high possibility of treating stroke patients using very small cell sacs called liposomes to bypass the blood brain barrier and carry lifesaving drugs to the brain to prevent damage following a stroke.

Oxygen-deprived tumor cells have survival advantage that promotes metastasis

Using cells from human breast cancers and mouse breast cancer models, researchers at the Johns Hopkins Kimmel Cancer Center say they have significant new evidence that tumor cells exposed to low-oxygen conditions have an advantage when it comes to invading and surviving in the bloodstream.
