Uric acid an endogenous aqueous antioxidant in normal humans is present in much higher concentrations than vitamin C and has
been known to cover 2/3rd of the free radical scavenging capacity in plasma. In the present study average uric acid levels of patients of rheumatoid
arthritis were found to be close to the normal individuals. A unique feature was observed after classifying the patients on
the basis of the duration of suffering, the patients having longer duration of disease had least uric acid levels as compared
to those suffering from relatively lesser period, similar trend was observed in the ascorbic acid estimations. The decline
in uric acid values with progression of the disease was much more than what was observed in case of ascorbic acid suggesting
the significant role of uric acid in scavenging of free radicals. Too much lowering of Uric Acid should be checked and vitamin
C should be supplemented in diet for maintaining the balance between pro oxidant and antioxidant forces to check pro oxidant
insult in rheumatoid arthritis. 相似文献

There has been increasing interest on the role of private foundations in education finance and delivery. We argue that this is due to a macro-policy context of stagnating levels of official development assistance for education and an uncritical acceptance of a logic of neutrality and the efficiency and effectiveness of of partnerships and philanthropy. This paper reports on the results of a literature review on private foundations in education and development. It found significant contestation against the claims of neutrality, efficiency, effectiveness. It also identifies salient methodological and substantive issues for the development of a research agenda on the issue. 相似文献

In the present study we have tried to trace the growth of malaria research at Global Level and the distribution of articles in various journals for the period 1955–2005. The data have been extracted from a database, which has been developed in-house from MEDLINE, SCI, TDB, Ovid Heath Information and Indian Science Abstracts. Study indicates that the exponential model fits the data on journals, articles and authors. The R2 value for the trend for journals, articles, and authors are 0.9502, 0.9475, and 0.9651, respectively. The growth rates for journals, articles and authors are 5.31%, 7.38%, and 10.06%, respectively. The linear multiple regression equation that Articles = ?39.2771 + 3.61719*journals + 0.085882*Authors (R2 = 99.16%) is most meaningful and it may be used to estimate the articles for given numbers of journals and authors. 相似文献

Lead exposure is increasingly becoming an important risk factor for osteoporosis. In adults, approximately 80–90 % of absorbed lead is stored in the bones. These bone lead deposits are released into the blood during periods of enhanced bone resorption like menopause, forming a potential endogenous source of lead exposure. Postmenopausal women are at a higher risk for bone lead release because of hormonal and age related changes in bone metabolism. Estrogen deficiency is associated with increase in osteoclasts number and activity leading to both the early and late form of osteoporosis. Hence, high blood lead level coupled with concomitant environmental exposure exposes women in this age group to lead related adverse outcomes like hypertension, reduced kidney and neurocognitive functions as well as increased risk of atherosclerosis and cardiovascular mortality. A few studies have also identified coexisting variates like ethnicity, occupation, residence, education, smoking, alcohol medications, water etc. as significant determinants of bone and blood lead in women, thus increasing the magnitude of postmenopausal bone changes. Hence, interventions focused on reducing the intensity of bone resorption during menopause will help decrease exposure to endogenous lead. This would play a significant role in decreasing the morbidity and mortality associated with menopause. Also, identification of modifiable factors that prevent bone lead release will reduce the risk of chronic lead exposure and improve the health outcomes of post-menopausal women. 相似文献

Infants were followed longitudinally to document the relationship between docosahexaenoic acid (DHA) levels and the development of attention. Erythrocyte (red-blood cell; RBC) phospholipid DHA (percentage of total fatty acids) was measured from infants and mothers at delivery. Infants were assessed in infant-control habituation at 4, 6, and 8 months augmented with psychophysiological measures, and on free-play attention and distractibility paradigms at 12 and 18 months. Infants whose mothers had high DHA at birth showed an accelerated decline in looking over the 1st year and increases in examining during single-object exploration and less distractibility in the 2nd year. These findings are consistent with evidence suggesting a link between DHA and cognitive development in infancy. 相似文献

In Part 11 of the article, we introduced the basic notions and techniques of mathematical logic. In this part, we present the completeness theorem of first order logic proved first by Gödel in 1929. We give a sketch of the proof due to Henkin. 相似文献
