background: rhabdomyosarcoma (rms) is one of the common malignant tumors in infants and children, but it is extremely rare in the kidney. in this paper, we present a case of rms the kidney of a child. case presentation: a 6-month old girl presented with agitation, low fever and abdominal distention which started 5 days ago. on physical examination, the infant had a large and firm soft tissue ma...

background: sonoelastography (se) is introduced as a complementary technique for ultrasoungraohy (us) to evaluate breast lesions. this method is based on tissue strain in response to compression and decompression. the current study was designed to investigate the diagnostic performance of se for differentiating between benign and malignant breast lesions methods: a total of 35 women with 45 bre...

The Na/Ca exchanger is associated with 160, 120 and 70 kDa polypeptides whose nature is poorly understood. We have purified and characterized the Na/Ca exchanger from bovine cardiac sarcolemmal vesicles (SLVs) by using ion-exchange and affinity chromatographies. The Na/Ca exchanger-enriched fraction was reconstituted into asolectin liposomes [lipid to protein ratio 10:1 (w/w)] that showed Na/Ca...

[1] In the San Luis Valley (SLV), Colorado legislation passed in 2004 requires that hydraulic head levels in the confined aquifer system stay within the range experienced in the years 1978–2000. While some measurements of hydraulic head exist, greater spatial and temporal sampling would be very valuable in understanding the behavior of the system. Interferometric synthetic aperture radar (InSAR...

Fifth order boundary value problem appears in the mathematical modelling of viscoelastic flows and other branches of mathematical, physical and engineering sciences [4, 5]. The conditions for the existence and uniqueness of the solution of such problems can be found in [6]. Gamel [2] analyzed Sinc-Galerkin method for the solution of fifth-order boundary value problems with two-point boundary co...

schwannoma is a solitary, slow growing,  benign tumour of the peripheral  nerve sheath, and it is most common locations are the head, neck, the flexor surfaces of the extremities, retroperitoneal and posterior mediastinium. external female genital organs are the least common location site of the schwannoma. only a few cases of vulvar schwannoma have been reported.we report 65 year- old woman pr...

the present study describes the fragmentation under electron ionization (ei) of gas phase serine and threonine amino acids. ab initio methods were performed to calculate the fragmentation paths and interpret the mass spectra. the six lowest energy conformers of l-serine, l-threonine and l-allo-threonine were obtained with b3lyp, g3mp2 and mp2 methods. the adiabatic and vertical ionization energ...

this study examined the possible effects of lycopene at physiological dosage and body fat mass on the humoral immune response in patients with type 2 diabetes mellitus (t2dm). a total of 35 patients with typ2 diabetes mellitus from both sexes aged 54±9 yrs from the iranian diabetes society were introduced into a double blind placebo controlled clinical trial conducted for 2 months. after a 2-we...
