The tooth structure preservation is the best way to postpone more invasive therapies. Especially in young patients more conservative techniques should be applied. Bonded porcelain veneers and even more the direct composite restorations, are the two therapeutic procedures that require the fewer sacrifice of dental tissue, finalized to the optimal recovery of aesthetic and functional outcome. Alt...

Background: There is some evidence suggesting a close relationship between polyunsaturated fatty acids (PUFAs) and renal inflammation and fibrosis, which are crucial stages in chronic kidney disease. Methods: To verify the role of PUFAs in renal fibrosis processes, we investigated the effects of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and arachidonic acid (AA) on the gene expres...

A range of individual nutrients and foods have been suggested to increase obesity risk in childhood, but the evidence is inconsistent. Dietary patterns that summarise the whole diet may, however, be more informative. The aim of the present paper was to systematically review the current evidence pertaining to overall dietary patterns in childhood and later obesity risk. Studies eligible for revi...

Volume 29, Number 3, May/June 1997 1980, the rate increased by 61% among adolescents, by 69% among women aged 20–24, by 67% among 25–29 year-olds and by 82% among women aged 30–34.2 Indeed, the rates for these latter groups have continued to rise since 1991, even as the birthrate among adolescents has stabilized and turned slightly downward. As a result of these trends, nonmarital births now ac...

Background: Literature review shows that there are not sufficient data about polyphenolic compounds of peel of Iranian pomegranate. So, this work was mainlyundertaken to determine phenolic compounds and antioxidant activity of dried peel of Iranian pomegranate. Methods: Pomegranate fruits were obtained from mature fruits grown in Saveh, Iran and the Pomegranate Peel (PP) were dried with three ...

Congestion pricing is one of the major travel demand management policies to reduce traffic volumes in metropolitans. One of the main factors for effective implementation of this policy is to analyze users' response to different toll rates. In this paper, the willingness of users to pay for using their personal cars is evaluated. The stated preference method was applied for data gathering. Sever...

ThehumanpregnaneX receptor (hPXR) is a xenobiotic-sensing nuclear receptor that transcriptionally regulates drug metabolism–related genes. The aim of the present study was to elucidate the mechanism by which hPXR is regulated through threonine-408. A phosphomimetic mutationat threonine-408 (T408D) reduced the transcriptional activity of hPXR and its protein stability in HepG2 and SW480 cells in...
