“…[13][14][15][16][17][18] Ultraviolet (UV) rays exert a negative effect on all antioxidants, especially on carotenoids. Therefore, an adequate intake of carotenoids in the form of vegetable and extra virgin olive oil (which contains β-carotene and lutein) has been recommended to obtain these important protective skin factors.…”

Recently, substantial interest has been generated in using electrospun biomimetic nanofibers of hybrids, particularly organic/inorganic, to engineer different tissues. The present work, for the first time, introduced a unique natural and synthetic hybrid micronanofiber wound dressing, composed of virgin olive oil/copper oxide nanocrystals and polyurethane (PU), developed via facile electrospinning. The as-spun organic/inorganic hybrid micronanofibers were characterized by scanning electron microscopy (SEM), energy dispersive X-ray analysis, X-ray diffraction, electron probe microanalysis, and transmission electron microscopy. The interaction of cells with scaffold was studied by culturing NIH 3T3 fibroblasts on an as-spun hybrid micronanofibrous mat, and viability, proliferation, and growth were assessed. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay results and SEM observation showed that the hybrid micronanofibrous scaffold was noncytotoxic to fibroblast cell culture and was found to benefit cell attachment and proliferation. Hence our results suggest the potential utilization of as-spun micronanoscaffolds for tissue engineering. Copper oxide–olive oil/PU wound dressing may exert its positive beneficial effects at every stage during wound-healing progression, and these micronanofibers may serve diverse biomedical applications, such as tissue regeneration, damaged skin treatment, wound healing applications, etc. Conclusively, the fabricated olive oil–copper oxide/PU micronanofibers combine the benefits of virgin olive oil and copper oxide, and therefore hold great promise for biomedical applications in the near future.

“…Benefits of increased intake of olive oil include its rapid digestibility, together with its reported anti-ulcer, anti-aging, stress and plasma cholesterol lowering properties, as well as therapy potentials for type 1 & 2 diabetes and skin care (Assmann et al, 1997;Christakis, Fordyce, & Kurtz, 1980;Owen et al, 2000;Ozyilkan, Colak, Akcali, & Basturk, 2005;Shah, Adams-Huet, Grundy, & Garg, 2004;Strychar et al, 2003;Visioli & Galli, 1998). Olive oil contains triglycerides composed mainly of oleic acid (monounsaturated fatty acid, MUFA) and a small amount of saturated fatty acid resulting in its poor storage stability (O'Brien, 2004).…”

“…Other investigations of highand low-carbohydrate diets in noninsulin-dependent [13,14,18,30,31] and insulin-dependent [16] diabetics have also observed that a low-carbohydrate high-fat diet results in a decrease in the levels of glucose and triglycerides when compared to baseline values.…”

“…A low-carbohydrate, higher fat diet, if incorporating beneficial fats (monosaturated fatty acids of a cis-confuguration), appears to be superior to a highcarbohydrate diet in achieving good glucose control as well as better lipid profile independent of weight loss, so long as the desired caloric content is maintained, in diabetic and glucose intolerant subjects [13][14][15][16][17][18]. In type 1 diabetics, a diet high in monounsaturated fats benefits fasting lipoprotein profiles [16]. Furthermore, when the insulin regimen is strictly tailored to individual requirements and carbohydrates are restricted to 30 g a day, both HbA 1c and lipid profiles dramatically improve compared to the baseline values when subjects eat an average carbohydrate diet [19].…”

Hyperglycemia of diabetes has been implicated in increased tissue oxidative stress, with consequent development of secondary complications. Thus, stabilizing glucose levels near normal levels is of utmost importance. Because diet influences glycemic control, this study investigated whether a low-carbohydrate (5.5%) diet confers beneficial effects on the oxidative status of the heart, kidney, and liver in diabetes. Male and female normal and diabetic rats were fed standard chow (63% carbohydrates) or low-carbohydrate diet for 30 days. Elevated glucose, HbA(1c), and alanine and aspartate aminotransferases in diabetic animals were reduced or normalized by the low-carbohydrate diet. While diabetes increased cardiac activities of glutathione peroxidase and catalase, low-carbohydrate diet normalized cardiac glutathione peroxidase activity in diabetic animals, and reduced catalase activity in females. Diabetic rats fed low-carbohydrate diet had altered activities of renal glutathione reductase and superoxide dismutase, but increased renal glutathione peroxidase activity in diabetic animals was not corrected by the test diet. In the liver, diabetes was associated with a decrease in catalase activity and glutathione levels and an increase in glutathione peroxidase and gamma-glutamyltranspeptidase activities. Decreased hepatic glutathione peroxidase activity and lipid peroxidation were noted in diet-treated diabetic rats. Overall, the low-carbohydrate diet helped stabilize hyperglycemia and did not produce overtly negative effects in tissues of normal or diabetic rats.
