Structure, Morphology and Electrical/Magnetic Properties of Ni-Mg Nano-Ferrites from a New Perspective.

Using the auto combustion flash method, Ni1-x+2Mgx+2Fe2+3O4 (x = 0, 0.2, 0.6, 0.

Aneurysmal degeneration of a saphenous vein graft following the repair of a popliteal aneurysm: case report and literature review.

True aneurysm formation in arterialized autologous veins is an unusual complication. A saccular aneurysmal degeneration of 53 mm (maximal diameter) of a saphenous vein graft inserted for repair of a popliteal aneurysm, four years after implantation, is reported. The patient (with prior history of abdominal aortic aneurysm) had been initially treated through a posterior approach.

Prediction equations for single-breath diffusing capacity in subjects aged 65 to 85 years.

Background: In senior subjects, diffusing capacity of the lung for carbon monoxide (Dlco) is interpreted using prediction equations derived from primarily younger adult populations. Our objectives were to provide reference equations for single-breath Dlco for a cohort of healthy, never-smoking, white, European adults between 65 and 85 years of age and to compare the predicted values of this sample with those from other studies involving middle-aged adults.

Methods: Reference equations were derived from a randomly selected sample from the general population of 431 healthy never smoker subjects aged 65 to 85 years (262 women and 169 men).

Lung volume reference values for women and men 65 to 85 years of age.

Rationale: In elderly subjects, static lung volumes are interpreted using prediction equations derived from primarily younger adult populations.

Objectives: To provide reference equations for static lung volumes for European adults 65 to 85 years of age and to compare the predicted values of this sample with those from other studies including middle-aged adults. We compare the lung volumes by plethysmography and helium dilution in elderly subjects.
