Investigations with the melphalan-resistant human rhabdomyosarcoma xenograft TE-671 MR were carried out to identify patterns of cross-resistance and collateral sensitivity and to define the mechanism(s) mediating melphalan resistance. TE-671 MR was cross-resistant to thio-TEPA, mitomycin, vincristine, and cisplatin, and partially resistant to chlorambucil and cyclophosphamide. TE-671 MR and the...
BACKGROUND The aim of the study was to evaluate congenital malformations and functional anomalies in the offspring of Swedish parents with thalidomide embryopathy (TE). METHODS Sixty-four children (29 girls, 35 boys) with ages ranging from 0-18 years, born to 34 Swedish parents (14 women, 20 men) with TE, were studied. Data on malformations and dysfunction were collected from medical records ...
Introduction & Objective : The aim of this study was to optimize MRI conventional protocols for BMD(Bone Mineral Density) measurements using MRI Relaxometry in systems not facilitated with special multi echo protocols. Since, cortical and trabecular bone separation can not be performed in DEXA, so the results might lead to erroneous interpretation of BMD values. One method for bone quality dete...
BACKGROUND AND PURPOSE Different TE can be used for obtaining MR spectra of brain tumors. The purpose of this study was to determine the influence of the TE used in brain tumor classification by comparing the performance of spectra obtained at two different TE (30 ms and 136 ms). METHODS One hundred fifty-one studies of patients with brain tumors (37 meningiomas, 12 low grade astrocytomas, 16...

در این مطالعه ویژگی های ساختاری از جمله ثابت های شبکه، مدول حجمی و الکترونی ترکیب های (X=S,Se,Te) AgGaX2 وCuSbX2 (X=S,Se,Te) در حالت انبوه در چارچوب نظریۀ تابعی چگالی و روش موج های تخت بهبود یافتۀ خطی با پتانسیل کامل (FP-LAPW) با استفاده از نرم افزار Wien2k محاسبه شده است. همچنین برای بررسی ویژگیهای الکترونی این ترکیب ها، چگالی حالت های کل، ساختار نواری، چگال...
The title compound, C(10)H(11)NTe, is the first organyl ethynyl telluride, R-Te-C C-H, to be structurally characterized. In the L-shaped mol-ecule, the aryl moiety, viz. Me(2)NC(6)H(4)Te, is almost perpendicular to the Te-C C-H fragment. The Te-Csp(2) bond [2.115 (3) Å] is significantly longer than the Te-Csp bond [2.041 (4) Å]. The Te-C C group is approximately linear [Te-C-C = 178.5 (4)° and ...
