In this paper, numerical solutions of the stochastic Fisher equation have been obtained by using a semi-implicit finite difference scheme. The samples for the wiener process have been obtained from cylindrical wiener process and Q-wiener process. stability and convergence of the proposed finite difference scheme have been discussed scrupulously. The sample paths obtained from cylindrical wiener process and Q-wiener process have also been shown graphically.

In this paper, we proof some properties of the space of bounded p(·)-variation in wiener’s sense. We show that a functions is of bounded p(·)-variation in wiener’s sense with variable exponent if and only if it is the composition of a bounded nondecreasing functions and h?lderian maps of the variable exponent. We show that the composition operator H, associated with , maps the spaces into itself if and only if h is locally Lipschitz. Also, we prove that if the composition operator generated by maps this space into itself and is uniformly bounded, then the regularization of h is affine in the second variable.

Background Klotho proteins （α- and β） are membrane-based circulating proteins that regulate cell metabolism, as well as the lifespan modulating activity of Fibroblast Growth Factors （FGFs）. recent data has shown that higher plasma circulating Klotho levels reduce cardio- vascular r.s., suggesting Klotho has a protective role in cardiovascular diseases. However, although so far it has been identified in various organs, it is unknown whether cardiomyocytes expr.s. Klotho and FGFs, and whether high cardiovascular r.s. could affect cardiac expr.s. sion ofKlotho, FGFs and other molecules. Methods We selected 20 patients with an estimated 10-year high ather.s.lerotic cardiovascular disease and 10 age-matched control subjects with an estimated 10-year low r.s. undergone cardiac surgery for reasons other than coronary artery by-pass. In myocardial biopsies, we evaluated by immuno-histochemistry whether Klotho and FGFs were expr.s.ed in cardiomyo- cytes, and whether higher cardiovascular r.s. influenced the expr.s.ion of other molecules involved in endoplasmic reticulum str.s., oxida- tive str.s., inflammation and fibr.s.s. r.s.lts Only cardiomyocytes of patients with a higher cardiovascular r.s. showed lower expr.s.ion of Klotho, but higher expr.s.ions of FGFs. Furthermore, higher cardiovascular r.s. was associated with increased expr.s.ion of oxidative and endoplasmic reticular.s.r.s., inflammation and fibr.s.s. Conclusions This study showed for the first time that Klotho proteins are ex- pr.s.ed in human cardiomyocytes and that cardiac expr.s.ion of Klotho is down-regulated in higher cardiovascular r.s. patients, while expr.s.ion of str.s.-related molecules were significantly increased.

To evaluate oxidative str.s. indices in follicular fluid (FF)by a novel thermochemiluminescence (TCL) assay and investigate the correlation between TCL and IVF cycle parameters. Pr.s.ective, cr.s.sectional study. IVF Unit of an Obstetrics and Gynecology Department in a universityaffiliated hospital. One hundred eightynine women undergoing consecutive IVF treatment cycles during 2001. After oocyte retrieval, pooled FF was centrifuged and the supernatant was tested in the TCL assay. Maximal serum E2 levels, number of gonadotropin ampoules, retrieved oocytes, mature oocytes, fertilization and cleavage rates, number of available embryos and cryopr.s.rved embryos, and clinical pregnancy rates and correlation with TCL indices. The TCL curve slope of FF positively correlated with maximal serum E2 levels, number of mature oocytes, and number of cleaved embryos and was inversely correlated with the womens ages and the number of gonadotropin ampoules. Follicular fluid TCL amplitude at 50 seconds ranged from 294 to 711 cps, but all pregnancies (n = 50; 28.1%) occurred within the range of 347-569 cps. With 385 and 569 cps as cutoff levels for the occurrence of pregnancy, the negative predictive value beyond this range was 96%and the positive predictive value within this range was 32%. The TCL r.s.lts may reflect the agerelated increase in free radical activity and is associated with parameters of ovarian r.s.onsiveness and IVF outcome. A certain thr.s.old of oxidative str.s. may be required for the occurrence of conception in IVF. TCL is a potential tool to evaluate, treat, and monitor antioxidant therapy in IVF treatments.

An asymptotic algorithm is applied to the problem of a finite, thermo-elastic solid containing a surface breaking crack, when the exterior.s.rface is subjected to oscillatory thermal loading. This algorithm involves the study of a model problem. An analytical and numerical study of this model problem of a thermo-elastic half space containing a surface breaking crack and subjected to oscillatory thermal loading is pr.s.nted. The crack surface is traction free. In particular, the amplitude of the str.s. intensity factor at the crack vertex is found as a function of the crack depth and the frequency of thermal oscillation.
