در گذشته تمرکز مطالعات دگرآسیبی بیشتر بر روی ارزیابی فعالیت سمیتی بقایای گیاهی و عصاره های آنها صورت می گرفت اما در سال های اخیر از طریق تاسیس و توسعه موسسه های علمی در سرتاسر جهان، پیشرفت های تکنیکی در زمینه این تحقیقات صورت گرفته و دانش دگرآسیبی طی دو دهه اخیر به علت ابداع روش های پیشرفته و همچنین همکاری بین دانشمندان و دستیابی به زیست آزمونهای مناسب، پیشرفت چشمگیری داشته است. از جمله روش های...

Acetaldophosphamide (A-ALD), a novel in vitro active and stable derivative of aldophosphamide, kills human bone marrow-derived granulocyte-macrophage colony-forming cells (GM-CFC) independent of the cell cycle. The surviving fraction of GM-CFC is an exponential function of the drug concentration and time of exposure. Variation of marrow light-density cell concentration between 2 x 10(6) and 10 ...

In this study we have performed a cell kinetic characterization of growth and growth arrest of keratinocytes derived from normal human skin. Proliferative activity of the cell cultures was analysed with a flow cytometric technique, measuring relative DNA content and iododeoxyuridine (IdUrd) incorporation simultaneously. Normal human keratinocytes were grown in keratinocyte growth medium (KGM) a...

The nonlinear density variation with temperature happens in many thermal applications like solar collectors, energy production, heat exchangers, and combustions, it gives a significant impact on transfer fluid flows. Thus, convective of an unsteady stagnation point flow under the influence gravity modulation presence water-based nanoparticles alumina (Al2O3) is studied here. Suitable variables ...

A two-dimensional natural convection flow of a viscous incompressible and electrically conducting fluid with both the viscosity thermal conductivity depending on temperature past vertical impermeable flat plate is considered in presence uniform transverse magnetic field. The governing equations are reduced to non-similar boundary layer by introducing coordinate transformations appropriate cases...

This study aims to analyze the style of greetings as a linguistic identity recognize poet and leader Buton community: A Kabhanti Bula Malino's manuscripts. Through an expressive approach descriptive method, data were analyzed through following steps: (1) text reading or techniques (listening-noting), (2) classification, (3) interpretation, (4) conclusion. The results analysis this showed that M...
