Synchronization of chaotic and Lu system has been done using the active sliding mode control strategy. Regarding the synchronization task as a control problem, fractional order mathematics is used to express the system and active sliding mode for synchronization. It has been shown that, not only the performance of the proposed method is satisfying with an acceptable level of control signal, but...

Unfertilized frog eggs arrest at the second meiotic metaphase, due to cytostatic activity of the c-mos proto-oncogene (CSF). MAP kinase has been proposed to mediate CSF activity in suppressing cyclin degradation. Using an in vitro assay to generate CSF activity, and recombinant CL 100 phosphatase to inactivate MAP kinase, we confirm that the c-mos proto-oncogene blocks cyclin degradation throug...

Evidence suggests that children's self-perceptions of their abilities predict their school achievement even after one accounts for their tested cognitive ability (IQ). However, the roles of nature and nurture in the association between school achievement and self-perceived abilities (SPAs), independent of IQ, is unknown. Here we reveal that there are substantial genetic influences on SPAs and t...

This study extends the research on cross-race identification by examining how group presentation of faces influences the cross-race effect (CRE) and confirming systematic qualitative differences between the cognitive processes involved in memory for same- and cross-race faces. White individuals viewed 16 target faces (8 White, 8 Black) presented individually or each in a 3-face group. The condi...

the study was carried out on 1300 in patients in isfahan medical school teaching hospitals during the last ten years. 1) 13.6% of patients complained pf pericardial pains but nothing wrong with their hearts. 2) more false pericardial pains were seen among young patients rather than c.h.d. in addition to these more false precardial pains among women with comparing to men. 3) the severity of c.h....

This is the fourth round in my interchange with Barbara Held about the nature and role of objectivity and causality as they relate to the rationale for scientific and scholarly legitimacy of case study knowledge. Throughout, I have found Held’s critical responses to my views collegially delivered and very helpful in stimulating me to clarify and expand upon my own thinking. In this fourth and f...

The plasma level of NO(x), i.e., the sum of NO(2)- and NO(3)-, is frequently used to assess NO bioavailability in vivo. However, little is known about the kinetics of NO conversion to these metabolites under physiological conditions. Moreover, plasma nitrite recently has been proposed to represent a delivery source for intravascular NO. We therefore sought to investigate in humans whether chang...

BACKGROUND AND PURPOSE Fluoxetine, a selective serotonin reuptake inhibitor, elevates brain concentrations of the neuroactive progesterone metabolite allopregnanolone, an effect suggested to underlie its use in the treatment of premenstrual dysphoria. One report showed fluoxetine to activate the aldo-keto reductase (AKR) component of 3α-hydroxysteroid dehydrogenase (3α-HSD), which catalyses pro...

The immune system plays an important role in shaping the clinical course of colorectal cancer (CRC). However, it is still unclear how the immune infiltrates of primary CRC lesions and distant metastases by immune effector cells are related to each other. To address this issue, we quantified CD3+, CD8+ and granzyme B+ lymphocytes in primary CRC samples and corresponding liver metastases. This an...
