objective(s):blactx-mand blaper are two genes that encode class a extended-spectrum β-lactamases (esbls) and can be responsible for therapeutic problems. this study was carried out to evaluate the molecular properties of these genes in clinical isolates of enterobacteriaceae by polymerase chain reaction (pcr), restriction digestion and sequencing. materials and methods: during six months, start...

the copper(ii) complex [cu(pic)2]·2h2o was synthesized with 2-picolinic acid (hpic) and copper acetate as reactants by room temperature solid-solid reaction. the composition and structure of the complex was characterized by elemental analyses, single crystal x-ray diffraction, x-ray powder diffraction, ft-ir spectroscopy and thermogravimetry-differential scanning calorimetry. the crystal struct...

background: interleukin-6 (il-6) is one of the inflammatory mediators characterized by elevated levels in ischemic stroke (is) patients. the present study set out to assess the role of il-6, as a marker for inflammation, in the severity and prognosis of acute is. methods: in a cross-sectional descriptive study, 45 patients with acute is were selected. patients with their first day of stroke wer...

conclusions the rapid dissemination of non clonal multi-resistant ctx-m-1 producing e. coli isolates approved the need for further studies in our medical centers. results a total of 140(70%) non-duplicate esbl positive e. coli were determined. imipenem and amikacin were effective against 100% and 85% of all tested isolates respectively. co-resistance of esbl positive isolates to erythromycin, t...

background: epigenetic reprogramming of differentiated cells can modify somatic cells into pluripotential state. pluripotency can be induced in somatic cells by several approches. one of the easy ways to induce pluripotency is the exposure of the somatic cells to the embryonic stem cell (esc) extract. objective: the objective of this study was to increase the efficiency of reprogramming of gran...

in this short article, we observe that the path of particle of mass $m$ moving along $mathbf{r}= mathbf{r}(t)$ under pseudo-force $mathbf{a}(t)$, $t$ denotes the time, is given by $mathbf{r}_d= int(frac{dmathbf{r}}{dt} mathbf{a}(t)) dt +mathbf{c}$. we also observe that the effective force $mathbf{f}_e$ on that particle due to pseudo-force $mathbf{a}(t)$, is given by $ mathbf{f}_e= mathbf{f} mat...
