Deoxygenation is a global problem in coastal and open regions of the ocean, and has led to expanding areas of oxygen minimum zones and coastal hypoxia. The recent expansion of hypoxia in coastal ecosystems has been primarily attributed to global warming and enhanced nutrient input from land and atmosphere. The largest anthropogenically induced hypoxic area in the world is the Baltic Sea, where ...

The cardiotoxic effects of adjuvant cancer treatments (i.e., chemotherapy and radiation treatment) have been well documented, but the effects on peripheral cardiovascular function are still unclear. We hypothesized that cancer survivors i) would have decreased resting endothelial function; and ii) altered muscle deoxygenation response during moderate intensity cycling exercise compared to cance...

Rapid transformatIon of discoid hemoglobin SS erythrocytes into grossly distorted sickled forms suggests alteration of surface/volume ratio. We, therefore, examined the effect of deoxygenation on red cell volume. ‘31llaholed albumin was used as a marker of plasma volume in normal (Hb AA), sickle (Hb SS), and sickle-C (Hb SC) blood. Heparinized blood was incubated for 30 mm at 37#{176}Cin a tpno...

Erythrocyte concentrates (ECs) stored for transfusion purposes still represent a lifesaving solution in a wide series of clinically occurring circumstances, especially for traumatized and perioperative patients. However, concerns still arise and persist as to whether current criteria for collection and storage of ECs might actually represent the best case scenario or there might rather be still...

Repeated sprint ability (RSA) is a critical success factor for intermittent sport performance. Repeated sprint training has been shown to improve RSA, we hypothesised that hypoxia would augment these training adaptations. Thirty male well-trained academy rugby union and rugby league players (18.4 ± 1.5 years, 1.83 ± 0.07 m, 88.1 ± 8.9 kg) participated in this single-blind repeated sprint traini...

Human-induced carbon emissions are altering the modern climate, with severe repercussions on ecosystems. Among others, anthropogenic pressure is causing deoxygenation of bottom water, widespread establishment hypoxic zones in several Mediterranean areas. The geological archives allow investigating past dynamics (sapropel events) and their impact marine Here, we compare causes evolution which oc...
