Lipomatous hypertrophy of interatrial septum (LHIS), usually found in echocardiography, is a rare non-neoplastic disease entity, which may cause arrhythmia or sudden death. We reported a case of LHIS associated with hypertrophic cardiomyopathy (HCM), which was suspected a hyperechoic intraatrial tumor in transthoracic echocardiography. Magnetic resonance (MR) imaging showed fat infiltration of ...

background and aims: from the past studies, it has been proved that consumption of heavy metals by humans may cause several chronicle problems like cancer, kidney and liver damage, high blood pressure and low blood pressure problems and etc. so, it has become very crucial to remove these heavy metals from industrial wastewater. the aim of this study was to find out a low cost and easy available...

an enzyme electrode was developed using the enzyme sulfite oxidase (ec1.8.3.1) immobilized onto pig intestine. hydrogen peroxide produced was monitored amperometrically. all experimental parameters such as ph, temperature, buffer constituent concentration, were thoroughly investigated and optimized when appropriate. the response to sulfite concentration was linear in the range 5.2´10-6 to 1.02´...

The incidence of ovarian cancer in women has been on the increase in recent years. The aim of the present study was to examine the effects of taxol on the expression of ovarian cancer-associated gene forkhead box transcription factor M1 (FoxM1) and its therapeutic effects for ovarian cancer. The expression of FoxM1 gene was examined in patients with or without ovarian cancer. RNA and protein le...

Ion channels are naturally occurring pores through the proteins that regulate the passage of ions and thus maintain the concentration of ions inside and outside the cell. The ion channels control many physiological functions and they can show selectivity for a specific ion. Ion channels are mostly observed in nerve cells and muscle cells. The influx of ions into cells can be regulated by a gate...

the ion-pair association constant values, related to the reaction +  were determined by means of the nmr spectroscopy. the values of the thermodynamic functions of the ion pairing process were calculated on the basis of the nmr results. in addition, the association entropy was found to be dependent on the temperature. comparing the experimental data and the fuoss theory it is found that  ion-pa...

in this paper, the photochemical degradation of azure-b by cu2+/s2o82− process has beenpresented. cu2+ as photocatalyst and s2o82− ion as photooxidant used in this process. atextremely low concentrations, cupric ion showed true catalytic activity in the overall process.the influence of various parameters on the performance of the treatment process has beenconsidered, such as ph, concentration o...

a new, simple, rapid, and cheap method for determination of trace amounts of nitrite ion is reported.determination is based on reduction of bromate ion by nitrite ion, in the presence of murexide inacidic media. during reaction of bromate ion with nitrite ion, the reaction mixture is decolorized.the absorbance changes is then monitored spectrophotometricaly at 520 nm, at 25 °c. dynamicrange of ...
