Delayed neurologic deficits, paraplegia and paraparesis, are devastating complications after repair of a descending thoracic and thoracoabdominal aortic aneurysm (TAAA). A treatment protocol has not been established, although strategies such as cerebrospinal fluid (CSF) drainage, maintaining blood pressure and medication have been described. Cerebrospinal drain status /oxygen delivery/patient s...

BACKGROUND Approximately 90 haemoglobinopathies have been identified that result in abnormally high oxygen affinity. One of these is haemoglobinopathy York (HbY), first described in 1976. HbY causes an extreme leftward shift of the oxygen dissociation curve with the P50 value changing to 12.5 - 15.5 mmHg (normal value 26.7 mmHg), indicating that approximately half of the haemoglobin is not avai...

The instability of climatic events intimidates the development crops at a global level, as it can cause serious economic and social consequences in face increased demand for food. In this scenario, use images early identification water stress is considered form non-destructive physical, biochemical, plant development-related responses. Water deficit responsible triggering series responses due t...

A 55 year old runner covered 160 km within a 20 hour period. His speed averaged 8.16 km/h, at an estimated 59.1% of maximum oxygen intake. After the first four hours of running, one of five fluids was taken in rotation every twelve minutes. Volumes ingested whe heart rate for the final four hours (125/min) was not increased relative to oxygen consumption for this portion of the run. Constancy o...

Activation of murine-derived J774.A1 macrophages with interferon gamma and lipopolysaccharide leads to a progressive mitochondrial defect characterized by inhibition of oxygen consumption and a decrease in the generation of ATP by oxidative phosphorylation. These changes are dependent on the generation of nitric oxide (NO) by an inducible NO synthase that becomes a significant consumer of oxyge...

CROWELL, JACK W., ROBERT G. FORD AND VIRGINIA M. LEWIS. Oxygen transport in hemorrhagic shock as a function of the hematocrit ratio. Am. J. Physiol. I g6(5) : I 033-1038. I g5g.-The oxygen consumption, arterial and venous oxygen concentration, and the arterial blood pH were measured, and the cardiac output, peripheral resistance and maximum oxygen transport capacity determined in 75 dogs with d...

The air-dried aerial parts of Lavandula angustifolia Mill, a traditional Uygur herbal drug, is used as resuscitation-inducing therapy to treat neurodisfunctions, such as stroke. This study was designed to assess the neuroprotective effects of lavender oil against ischemia/reperfusion (IR) injury in mice. Focal cerebral ischemia was induced by the intraluminal occlusion method with a nylon strin...

Constraining the core’s composition is essential for understanding Earth accretion, core formation and sustainment of Earth’s magnetic field. outer inner exhibit a density deficit relative to pure iron, attributed presence substantial amounts low atomic number ‘light’ elements, such as sulfur, silicon, oxygen, carbon hydrogen. However, owing its inaccessibility, estimates can only be indirectly...

Aging is very often associated with magnesium (Mg) deficit. Total plasma magnesium concentrations are remarkably constant in healthy subjects throughout life, while total body Mg and Mg in the intracellular compartment tend to decrease with age. Dietary Mg deficiencies are common in the elderly population. Other frequent causes of Mg deficits in the elderly include reduced Mg intestinal absorpt...
