Low oxygen levels in the heart have long been known to produce life-threatening arrhythmias, even sudden death. Until now, it has not been clear how. "Our research shows that within seconds, at low levels of oxygen (hypoxia), a protein called small ubiquitin-like modifier (SUMO) is linked...

Life at stable low oxygen levels: adaptations of animals to oceanic oxygen minimum layers. Zones of minimum oxygen level are found at intermediate depths in most of the world's oceans and, although the oxygen partial pressure in some of these 'oxygen minimum layers' is only a fraction of a...
In the complex landscape of cancer, tumors create their own microenvironment, often marked by low oxygen levels, a condition known as hypoxia. Hypoxia arises as tumors grow rapidly, outpacing their blood supply due to the lack of an efficient vascular system within the tumor. This oxygen-starved...
Hypoxemia specifically refers to low oxygen levels in the blood, which can lead to the following symptoms: Shortness of breath (dyspnea): This is often the most prominent symptom of hypoxemia. It's a sensation of not being able to get enough air, which can be mild to severe, depending on...
Hypoxemia ranges from mild to severe, but even a mild decrease in blood oxygen requires medical evaluation to determine the underlying cause and best treatment.Signs and symptoms develop when a low blood oxygen level leads to an oxygen deficiency in the body tissues, which is known as hypoxia....
Low oxygen levels in the heart have long been known to produce life-threatening arrhythmias, even sudden death. Until now, it was not clear how. New findings, in a study led by Steve A. N. Goldstein, MD, Ph.D., vice chancellor for Health Affairs at the University of California, Irvine...

water masses than in waters below the redoxcline28. Thus, we selected lowest Ce/Ce* values for a given time interval and considered the statistical distribution of sample numbers. We then used the relationship between Ce/Ce* in carbonates and pO2to estimate atmospheric oxygen levels in the ...
In addition, low O22 tension is required for the generation of high-affinity, somatically hypermutated antibodies [4]. Consistent with these observations, proximity to nodal blood vessels and their higher O22 levels impairs development of B cell follicle into GC [6]. This evidence shows that GC...
