Escherichia coli O157:H7 is found in cattle farms and can live in the intestine of healthy cattle. Mostcases of human illnesses including nonbloody diarrhea, hemorrhagic colitis and hemolytic uremic syndromecan be traced, either directly or indirectly, to cattle. One strategy for reducing the risk of EnterohemorrhagicEscherichia coli (EHEC) infections in human is to reduce the prevalence of inf...

BACKGROUND Large disasters affect people who live both near and far from the areas in which they occur. The mental health impact is expected to be similar to a ripple effect, where the risk of mental health consequences generally decreases with increasing distance from the disaster center. However, we have not been able to identify studies of the ripple effect of man-made disaster on mental hea...

AIM This study evaluated in vitro microleakage of inlays made by direct or indirect techique with or without fiber reinforced composite (FRC) substructure. MATERIALS AND METHODS Standardized mesio-occlusal cavities were prepared and restored using direct-technique with composite resin only or FRC-composite resin, and indirect technique with laboratory composite only or FRC-laboratory composit...

Myogenic microRNAs are important regulators of muscle development and differentiation. To better understand the roles of chromatin-modifying and remodeling enzymes in the activation of myogenic microRNA expression, we have functionally analyzed two different protein arginine methyltransferases, Prmt5 and Prmt4, both of which have previously been implicated in the regulation of myogenic mRNA exp...

We reported elsewhere that orexin neurons are directly hyperpolarized by noradrenaline (NA) and dopamine. In the present study, we show that NA, dopamine, and adrenaline all directly hyperpolarized orexin neurons. This response was inhibited by the alpha2 adrenergic receptor (alpha2-AR) antagonist, idazoxan or BRL44408, and was mimicked by the alpha2-AR-selective agonist, UK14304. A low concent...

Buthotus schach Finally, according to our results venom as well as fractions F4 and F6 act mostly prejunctionally on Ach release. More attempt is carrying out to study their effects on ion channel activities. is one of the most dangerous scorpions in tropical part of Iran. The effects of its crude venom at 1, 3, 10 µg/mL and its obtained fractions by gel filtrations were investigated on neuromu...

Academic achievement is a function of many factors among which the school entry age has been controversial. Although the impact of the age factor is rather obvious, its effect is mediated by factors such a spiritual intelligence, social skills, and creativity. In order to devise a structural model by which the academic achievement can be predicted, a sample of 250 female 10th graders was select...

An attempt is made to define the concept of execution of an instruction sequence. It is found to be a special case of directly putting into effect of an instruction sequence. Directly putting into effect of an instruction sequences comprises interpretation as well as execution. Directly putting into effect is a special case of putting into effect with other special cases classified as indirectl...
