background: brucellosis is an endemic zoonotic disease in the middle east. this study intended to design a uniplex pcr assay for the detection and differentiation of brucella at the species level and determining the antibiotic susceptibility pattern of brucella in iran. methods: sixty-eight brucella specimens (38 animal and 30 human specimens) were analyzed using pcr (using one pair of primers)...

abstract   background: obesity is directly related to dyslipidemia which contributes significantly to the risk of coronary heart disease, a major cardiovascular disease and a serious health problem. the aim of this study was to compare the effects of low calorie diet and those of lovastatin on serum lipoproteins, apo b, homocysteine, and total antioxidant capacity (tac) in hyperlipidemic obese ...

background: diabetic patients have a higher prevalence of non-dipping pattern in blood pressure (bp) than general population. non-dipping arterial pressure pattern is associated with increased cardiovascular risk. the objective of this study was to investigate the association between the clinical and paraclinical characteristics of the diabetic patients with circadian bp variability. m aterials...

In this paper, we introduce the notion of an (a, b)-rectangle pattern on permutations which is closely related to the notion of successive elements (bonds) in permutations and to mesh patterns introduced recently by Brändén and Claesson. We call the (k, k)-rectangle pattern the k-box pattern. We show that we can derive an explicit formula for the number of permutations of Sn which have the maxi...

In the present study, modified nucleotides in the B. subtilis tRNA(Trp) cloned and hyperexpressed in E. coli have been identified by TLC and HPLC analyses. The modification patterns of the two isoacceptors of cloned B. subtilis tRNA(Trp) have been compared with those of native tRNA(Trp) from B. subtilis and from E. coli. The modifications of the A73 mutant of B. subtilis tRNA(Trp), which is ina...

Lymphoid recovery following myeloablative stem cell transplantation (SCT) displays a logistic pattern of exponential growth followed by a plateau. Within this logistic framework, lymphoid recovery is characterized by the parameters R (slope of ascent), a (time of maximal rate of ascent) and K (plateau), the 'steady-state' lymphocyte count. A retrospective analysis of allogeneic SCT performed fr...

The atherogenic lipoprotein phenotype (ALP) is a common heritable trait characterized by a predominance of small, dense low density lipoprotein (LDL) particles (subclass pattern B), increased levels of triglyceride-rich lipoproteins, reductions in high density lipoprotein, and a 3-fold increased risk of myocardial infarction. Significant two-point linkage was found between ALP and the LDL recep...

OBJECTIVE To evaluate the role of transvaginal power Doppler sonography to discriminate between benign and malignant endometrial conditions in women presenting with postmenopausal bleeding and thickened endometrium at baseline sonography. METHODS Ninety-one postmenopausal women (median age, 58 years; range, 47-83 years) presenting with uterine bleeding and a thickened endometrium (> or = 5-mm...

In this pepper Fe2O3 nanoparticles were synthesized via a fast microwave method. Then Fe2O3-TiO2 nanocomposites were synthesized by a sonochemical-assisted method. The prepared products were characterized by X-ray diffraction pattern, scanning electron microscopy and Fourier transform infrared spectroscopy. The photocatalytic behaviour of Fe2O3-TiO2 nanocomposites was evaluated using the degrad...

An n × n sign pattern A is spectrally arbitrary if given any self-conjugate spectrum there exists a matrix realization of A with that spectrum. If replacing any nonzero entry (or entries) of A by zero destroys this property, then A is a minimal spectrally arbitrary sign pattern. For n ≥ 3, several families of n × n spectrally arbitrary sign patterns are presented, and their minimal spectrally a...
