this study was conducted to evaluate the effect of soy milk on serum 17- β estradiol level and number of neurons in cerebral cortex and hippocampus as well as determination of the ratio of neurons in cortical and hippocampal regions in neonatal ovariectomized rats. thirty female rats (one day old) were divided into six groups of five. at day 7, ovariectomy surgery was performed in four groups a...

mcm-41 is one of the groups of mesoporous materials that have wide applications as adsorbents, ion exchangers and catalyst supports. in this work spherical and rod-like mcm-41s were synthesized in homogeneous and heterogeneous reaction media, respectively. for synthesis of these materials the cationic surfactant cetyltrimethylammonium bromide (ctmabr) was used as template and tetraethylorthosil...

An emerging trend in the engineering of complex systems is the use of component integration frameworks. Such a framework prescribes an architectural design that permits flexible composition of third-party components into applications. A good example is Sun Microsystems’ Enterprise JavaBeans (EJB) framework, which supports objectoriented, distributed, enterprise-level applications, such as accou...

1,3-dipolar cycloaddition reaction of 1 mol or 2 mol of dibenzalaceton with 1 mol of non-stabilized azomethinylides generated in situ by decarboxylative condensation of isatin and proline or sarcosine give the novel new spiro-oxindolo(pyrrolizidines/ pyrrolidines) instead of bis-spirooxindolo( pyrrolizidines/ pyrrolidines).

a simple, rapid and sensitive hplc method for the determination of theophylline (t) in human serum has been developed. an isocratic system consisting of a /-l bondapak c18 column, mobile phase of methanol, phosphate buffer (22:78, ph=4.5), and a flow rate of 1.4 ml/min was used. the eluent was detected by uv at 275 nm at room temperature. 8-chlorotheophylline (8-ct) was used as an internal stan...

coordination of cu+ ions adsorbed on plausible sites of a silicalite-2 lattice has been investigated computationally via hybrid density functional theory method at the b3lyp/6-311+g* and b3lyp/def2-tzvp levels of theory using molecular models of the active site. the symmetrical coordination of cu+ ions to almost five oxygen atoms of the all-silica framework in six-membered ring (6mr) sites of t...

objective: parkinson's disease (pd) is one of the most common neurodegenerative disorders which is characterized by tremor, rigidity, bradykinesia and postural disturbances. studies indicate that grape juice and exercise may have beneficial effects on neurodegenerative disorders. therefore, in the present study, we evaluated the effects of red grape juice (gj) together with treadmill runni...

conclusions some il-10 promoter gene polymorphisms predisposed the infected hepatitis b virus cases to cirrhosis in our study population. patients and methods totally, 166 patients with chronic hepatitis b infection were enrolled. genotypes at different positions (i.e. -819, - 592, and - 1082) in the il-10 gene promoter were determined. results the c/a genotype at position -592, c/t genotype at...
