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.

Researchers find new insights on disease stages for gastric cancer patients

Diagnosis of gastric cancer in the early stages is difficult because of the lack of simple and cheap methods of inspection and specific markers of gastric cancer while the symptoms of the disease are vague and tend to overlap with other common and benign conditions. Better tumor characterization and more individualized treatment planning can be expected only with the implementation of better diagnostic tools combined with advances in molecular and genetic analysis.

Increased expression of VEGF-A promotes three common aging-related eye conditions

A Massachusetts General Hospital investigator has found that increased expression of the angiogenic factor VEGF-A promotes three common aging-related eye conditions - both versions of age-related macular degeneration (AMD) and also cataracts - in an animal model.

Study links effects of prenatal alcohol and drug exposure with placental development

In the United States, prenatal alcohol exposure (PAE) is the most common preventable cause of developmental delay. Animal studies have shown some of the adverse effects of PAE on placental development, but few studies have examined these effects in humans. This is the first study to examine the effects of prenatal exposure to methamphetamine, marijuana, and cigarette smoking on human placental development.

Inhalable form of Ambrisentan drug could offer faster-acting treatment option for pulmonary edema

In a new study, researchers show an aerosolized, inhalable form of the drug Ambrisentan could offer a faster-acting treatment option for pulmonary edema, a life-threatening condition in which fluid accumulates in the lungs. Pulmonary edema is a significant risk for anyone spending time at high altitudes, and also affects people with chronic conditions including congestive heart failure and sickle cell anemia.

Low-oxygen conditions spur growth of breast cancer stem cells

Working with human breast cancer cells and mice, scientists at The Johns Hopkins University say new experiments explain how certain cancer stem cells thrive in low oxygen conditions. Proliferation of such cells, which tend to resist chemotherapy and help tumors spread, are considered a major roadblock to successful cancer treatment.

Orexigen Therapeutics, Valeant Pharmaceuticals sign distribution agreement for Mysimba

Orexigen Therapeutics, Inc. today announced Valeant Pharmaceuticals International, Inc. will commercialize Mysimba (naltrexone HCl / bupropion HCl prolonged release) in Central and Eastern Europe.

Regulatory immune cells compromised in PAH

Research suggests that regulatory T cells may play a part in all subtypes of pulmonary arterial hypertension.

Wistar researchers find potential way for using STAT3 inhibitors to stop cancer progression

Imagine developing a drug designed to inhibit a protein that helps cancer cells proliferate and survive only to find that the drug does not perform very well in the clinic. This was the dilemma faced by scientists researching inhibitors of signal transducer and activator of transcription (STAT3), a protein that controls transcription by the STAT3 gene.

Eisai's Halaven receives FDA approval for treatment of patients with metastatic liposarcoma

Eisai Inc. announced today that the U.S. Food and Drug Administration approved Halaven (eribulin mesylate) Injection (0.5 mg per mL) for the treatment of patients with unresectable or metastatic liposarcoma who have received a prior anthracycline-containing regimen.

New blood biomarkers could lead to better evaluation of treatment for patients with PAH

New blood biomarkers reflecting vasoreactivity in lung blood vessels of patients with heart- and lung disease, can lead to simplified diagnostics and better evaluation of treatment for patients with the condition pulmonary arterial hypertension (PAH).

Low-oxygen exposure shortly after birth may increase learning and behavioral disorder risks

New research published in the Journal of Leukocyte Biology, shows that the development of white matter in the mouse brains is delayed when they are exposed to chronic low oxygen levels shortly after birth.

Study reveals pathogenetic role of miR-125a in pulmonary hypertension

Pulmonary hypertension is an umbrella term used for many conditions that all result in elevation of the pulmonary arterial pressure. Of interest, many of these completely different clinical and pathophysiological entities result in a final common pathway of vasoconstriction, micro thrombosis and vascular remodelling.

New technique may enable in-flight detection of hypoxia in pilots

Researchers working in the United States have demonstrated a technique that may enable real-time, in-flight detection of hypoxia in pilots.

Sleep apnea may increase gout risk

Sleep apnea may increase the risk of developing gout, a new study shows. Among 9865 patients with newly-diagnosed sleep apnea and 43,598 comparators of similar weight, investigators identified 270 new cases of gout over one year of follow-up, resulting in incidence rates of 8.4/1000 and 4.8/1000 person-years, respectively. The increased risk of gout was 60% higher among patients with sleep apnea.

Diabetic retinopathy therapy innovations: an interview with Richard Kirk, CEO of Polyphotonix

In the UK there are currently over 3.5 million people who have diabetes, with a growth rate exceeding 280,000 people per year. Diabetic retinopathy is the most common complication of diabetes.

Genetic polymorphisms may serve as prognostic markers for lung cancer

Genetic polymorphisms associated with cancer progression lead to variations in gene expression and may serve as prognostic markers for lung cancer. Researchers at the Hiroshima University and Saitama Medical University found that in patients with lung cancer, a single nucleotide polymorphism (SNP) may regulate gene and protein expression and be associated with poor prognosis.

Researchers discover new way to stop cancer cells from spreading

Researchers at the Francis Crick Institute and the University of Copenhagen have discovered a new way to potentially 'fence in' a tumour and help stop cancer cells spreading, according to a Cancer Research UK funded study published in EMBO Reports today, (Thursday).

Terminally ill patients with certain subtypes of delirium show higher probability of imminent death

In cancer patients nearing the end of life, certain subtypes of delirium—specifically, hypoactive and "mixed" delirium—are a strong indicator that death will come soon, reports a study in Psychosomatic Medicine: Journal of Biobehavioral Medicine, the official journal of the American Psychosomatic Society.

Specific biomarker predicts which HER2-negative breast cancer patients respond to targeted therapy

A multicenter team led by Case Western Reserve has demonstrated that brief exposure to a targeted therapy can tell doctors which HER2-negative patients will respond — and which should switch to another kind of treatment.
