The Positive Association of Plasma Levels of Vitamin C and Inverse Association of VCAM-1 and Total Adiponectin with Bone Mineral Density in Subjects with Diabetes.

Context: Population studies have shown a trend in decreasing vitamin C status and increasing prevalence of osteoporosis in patients with diabetes and non-diabetic people. Dietary vitamin C consumption is linked to improvement in bone mineral density (BMD) in epidemiological studies. VCAM-1 and adiponectin are known to activate osteoclasts, which increase bone loss.

Assessment of a Prototype Apache Flight Eyewear.

Background: Apache pilots needing refractive correction are issued modified HGU-4/P aviator spectacles. However, a recently published survey found field of view (FOV) dissatisfaction with the current spectacles when sighting in with a Helmet Display Unit (HDU). A current Air Force flight frame was modified in-lab and the purpose of this study was to evaluate the FOV with the current Apache flight frame vs.
