Neuroendocrine tumors (NETs) with oncocytic features are rare. To date, few studies have described the metastatic characteristics of these tumors, most which were limited by low number cases. One article characterized intermediate to high grade (G2 and G3) NETs pancreas as having an ominous outcome; however, low-grade have, our knowledge, been hitherto unexplored. Our study clinicopathological ...
the present study was conducted to investigate the effect of implicit focus on form through input flooding and the effect of noticing, explicit focus on form on linguistic accuracy. to fulfill the purpose of the study, 86 iranian pre-intermediate efl learners of one of the language institutes were chosen by means of administering ket as the homogeneity test. these learners were pretested throug...
this study aimed at examining the effects of iranian efl learners’ anxiety, ambiguity tolerance, and gender on their preferences for corrective feedback (cf, henceforth). the effects were sought with regard to the necessity, frequency, and timing of cf, types of errors that need to be treated, types of cf, and choice of correctors. seventy-five iranian efl students, twenty-eight males and forty...
abstract this study aimed at investigating the effect of bilingual teaching of cognate words (persian-english) on iranian upper intermediate efl learners’ knowledge of lexical development. for this purpose,100 subjects participated in this study out of which 40 learners were selected for this study and they were assigned into two groups, control and experimental. cross-language cognates (wor...
1,2-Dichloro-3,3,4,4,5,5-hexafluorocyclopentene (F 6 cypCl 2 ) was functionalized with diphenyl- and dimesitylphosphanyl groups by a salt-elimination reaction of the respecttive chlorophosphane (PPh Cl, PMes Cl) in situ generated lithiated F cyp(Li)Cl. cyp(PR )Cl (R = Ph, Mes) functionalised again to obtain corresponding trimethylstannyl substituted compounds )(SnMe 3 Mes). These tin-precursors...
A high-level computational study using CCSD, CCSD(T), and G2(+) levels of theory has shown that unactivated vinyl substrates such as vinyl chloride would afford gas phase, single-step halide exchange by a pure in-plane sigma-approach of the nucleophile to the backside of the C--Cl sigma bond. Geometry optimization by CCSD/6-31+G* and CCSD(T)/6-31+G* confirms the earlier findings of Glukhovtsev,...
Abstract Background The aim of the study was to assess whether configuration primary soft-tissue sarcoma (STS) on MRI correlates with grade malignancy. Patients and methods 71 patients histologically proven STS were included. Primary examined for configuration, borders, volume MRI. tumors divided into high-grade (G3), intermediate-grade (G2) low-grade (G1) according grading system French Federa...
An alkali-halophilic archaeum, Natronomonas pharaonis, contains two rhodopsins that are halorhodopsin (phR), a light-driven inward Cl- pump and phoborhodopsin (ppR), the receptor of negative phototaxis functioning by forming a signaling complex with a transducer, pHtrII (Sudo Y. et al., J. Mol. Biol. 357 [2006] 1274). Previously, we reported that the phR double mutant, P240T/F250Y(phR), can bin...
Chemotherapy drugs have been prescribed for the systemic treatment of cancer. We selected three chemotherapy drugs, including methotrexate, mitomycine C and vincristine to inhibit the proliferation of HT1080 human fibrosarcoma cells in S, G2 and M phases of the cell cycle respectively. These chemotherapy drugs showed significant toxicity and growth inhibition to the cancer cells measured by MTT...
Mung bean nuclease treatment of 16S-23S ribosomal DNA intergenic transcribed spacers (ITS) amplified from several strains of the six species of the Bacillus cereus group showed that B. anthracis Davis TE702 and B. mycoides G2 have other intermediate fragments in addition to the 220- and 550-bp homoduplex fragments typical of the B. cereus group. Long and intermediate homoduplex ITS fragments fr...
