background leptospirosis is a systemic infectious disease caused by pathogenic bacteria belonging to the species of leptospira, it is considered to be the most common zoonosis in the world. this is a serious and sometimes fatal infection which is transmitted from animals to humans by entering the digestive tract or mucosal membrane. within the initial 10-12 day period, the patient may experienc...

Myocardial ATP utilization and resynthesis during hypoxia and reoxygenation were studied in vivo as a function of maturation. Graded hypoxia was performed in newborn (NB; 4-10 days old, n = 6) and mature sheep (MAT; 30-60 days old, n = 6). Time-resolved 31P-nuclear magnetic resonance was used to monitor myocardial phosphates throughout hypoxia and to monitor reoxygenation concomitant with rate ...

Let A be a well-formed formula of first-order modal logic whose only free variable is x. We shall use the following abbreviations: Mat(A) for (x)[OA * 0~A] Form(A) for (x)[DA vD-i] Ban(A) for ((x)DA) v ((x)U~A) Pred(A) for Form(A) v Mat(A). We read Mat(A), FormjA), and Ban(A) respectively as: "A is material", "A is formal", and "A is banal"; Pred(A) is the assertion of the Principle of Predica-...

Sexual reproduction plays a critical role in the infection cycle of Fusarium graminearum because ascospores are the primary inoculum. As a homothallic ascomycete, F. graminearum contains both the MAT1-1 and MAT1-2-1 loci in the genome. To better understand their functions and regulations in sexual reproduction and pathogenesis, in this study we assayed the expression, interactions, and mutant p...

We investigated the mechanism of nitric oxide (NO) action on hepatic methionine adenosyltransferase (MAT) activity using S-nitrosoglutathione (GSNO) as NO donor. Hepatic MAT plays an essential role in the metabolism of methionine, converting this amino acid into S-adenosylmethionine. Hepatic MAT exists in two oligomeric states: as a tetramer (MAT I) and as a dimer (MAT III) of the same subunit....

The diurnal variation in the microgradients of O(2), H(2)S, and Eh were studied in the benthic cyanobacterial mats of a hypersaline desert lake (Solar Lake, Sinai). The results were related to light intensity, light penetration into the mat, temperature, pH, NH(4), photosynthetic activity, pigments, and the zonation of the microbial community. Extreme diurnal variation was found, with an O(2) p...

background: toxoplasma gondii is a zoonotic protozoan parasite found worldwide and responsi­ble for major economic losses in most classes of livestock. this study was aimed to deter­mine the prevalence of t. gondii infection in sheep, cattle and horses in urmia, north-west of iran, using mat. methods : blood samples of 276 livestock and 26 horses were collected from july 2009 till april 2010. t...
