Ascorbic acid does not affect the age-associated reduction in maximal cardiac output and oxygen consumption in healthy adults.

Maximal aerobic capacity (Vo(2max)) decreases progressively with age, primarily because of a reduction in maximal cardiac output (Q(max)). This age-associated decline in Vo(2max) may be partially mediated by the development of oxidative stress that can suppress beta-adrenergic-receptor responsiveness and, consequently, reduce Q(max). To test this hypothesis, Vo(2max) (indirect calorimetry) and ...

Arterial oxygen desaturation during esophagogastroduodenoscopy.

This prospective study evaluated the incidence and severity of arterial oxygen desaturation during esophagogastroduodenoscopy (EGD) and assessed clinical factors in relation to arterial oxygen desaturation. Following pulmonary function testing, 192 patients underwent elective EGD with continuous recording of arterial oxygen saturation (SaO2). 62 patients (32.3%) showed arterial oxygen desaturat...

KIR Gene Content Does Not Contribute to Susceptibility to Graves’ Disease

Background: Killer cell immunoglobulin-like receptors (KIR) are expressed on NK cells and a subset of T cells. The variable KIR receptors along with their ligands, HLA class I, influence risk for autoimmune and malignant diseases. Objective: To investigate the KIR gene profiles in relation to susceptibility to Graves’ disease in patients with ophthalmopathy. Methods: KIR genes profiles were ana...

Arterial oxygen desaturation after induction of anesthesia.

To the Editor:—Naguib et al. have presented a clinically relevant study of arterial saturation values after preoxygenation and different doses of suxamethonium, and discuss their results using the extensive reports relevant to this topic. Unfortunately, they perhaps did not search the published work back to times before the pulse oximeter was introduced. Before the pulse oximeter, the Hewlett P...

Moderate dose of watercress and red radish does not reduce oxygen consumption during graded exhaustive exercise

Objective: Very recent studies have reported positive effects of dietary nitrate on the oxygen consumption during exercise. This research aimed to study the effect of moderate dose of high-nitrate vegetables, watercress (Nasturtium officinale) and red radish (Raphanus sativus) compared with a control group on the incremental treadmill exercise test following a standard Bruce protocol controlled...
