The aim of the present study was to assess the effects of sprouty homolog 2 (SPRY2) gene regulation by miR-21 on the occurrence, development and tumor metastasis in multiple myeloma (MM). The miR-21 expression lentiviral vector (LV)-anti-miR-21 and a liposome transfection method were used to screen MM cell lines with stable silent SPRY2. Real-time quantitative polymerase chain reaction (PCR) an...
We previously reported that a transgemc mouse line containing the fetal globin promoter linked to the SV4O T antigen (T Ag) viral oncogene (G71f-15) resulted in prostate tumors. In this study, we further explored tumor origin, frequency, invasiveness, androgen sensitivity, and gene expression pattern. T Ag was detected in adult but not fetal and neonatal prostates, suggesting a role for androge...

It is clear that the Indian subcontinent is not free of these problems, and it is a major risk factor for coronary heart disease. Glycosylated haemoglobin (HbA1c) is included as a measure of diabetic control in studies publis...
D-Glucosamine has been shown to have a powerful cytotoxic effect on various ascites tumor lines, resulting in a decrease in viability and transplantability of the neoplastic cells. The toxic effect of glucosamine was not significantly altered by addition of either glucose or pyruvate. The effects of D-glucosamine and other sugar analogs were evident histologically even before the cells became s...
what has been discussed here has been a study of international immigration law. this branch of law has not been a major player in the field of international law. no collective law exists, and no codification has been carried out as yet. however, the need for such a set of laws has forced the international community to pay more attention to this issue. the need for a better life in the so-call...
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
abstract this study evaluates the iranian pre-university english textbook in terms of needs, objectives, content, and methodology. the study was designed on the qualitative- quantitative survey basis using interviews and questionnaires, a researcher-made textbook evaluation checklist and a needs analysis questionnaire. the textbook evaluation questionnaire was used in this study to elicit the ...
with the growth of more humanistic approaches towards teaching foreign languages, more emphasis has been put on learners’ feelings, emotions and individual differences. one of the issues in teaching and learning english as a foreign language is demotivation. the purpose of this study was to investigate the relationship between the components of language learning strategies, optimism, duration o...
