Ultraviolet radiation damage to the skin is due, in part, to the generation of reactive oxygen species. Vitamin C (L-ascorbic acid) functions as a biological co-factor and antioxidant due to its reducing properties. Topical application of vitamin C has been shown to elevate significantly cutaneous levels of this vitamin in pigs, and this correlates with(More)
Several events are associated with cellular aging: alterations in the extracellular matrix, loss of the cell's proliferative capacity, and decreased responsiveness to growth factors. In skin, a major component of the extracellular matrix is collagen; an important regulator of collagen synthesis is ascorbic acid, which may also have growth factor-like(More)
Studies were conducted to determine the relationship between dietary vitamin E (VE) and the development of nutritional pancreatic atrophy (NPA) in selenium (Se)-deficient chicks. Selenium- and VE-depleted chicks reared on a low Se, amino acid-based diet containing 100 IU VE (as all-rac-alpha-tocopheryl acetate) per kilogram were found to have exceedingly(More)
Studies were conducted to determine whether nutritional selenium (Se) status affects the nutritional status of the chick with respect to other trace elements, particularly copper (Cu) and Zinc (Zn). Severe Se deficiency was produced in chicks by the use of diets that contained exceedingly low contents (less than 0.010 ppm) of Se, but contained adequate(More)

OBJECTIVE To discuss the use of magnetic resonance angiography (MRA) imaging as a definitive means to assess vascular patency and the relative value of various vertebral artery screening maneuvers. CLINICAL FEATURES Two female patients suffered head and neck trauma with possible vertebral artery insufficiency. Positive vertebral artery screening tests(More)
INTRODUCTION Community-based participatory research (CBPR) has great potential to address cancer disparities, particularly in racially and ethnically diverse and underserved neighborhoods. The objective of this study was to conduct a process evaluation of an innovative academic-community partnership, Queens Library HealthLink, which aimed to reduce cancer(More)
