One of the most important issues in ground based wood extraction in forestry is to minimize the soil damage caused by heavy forestry machines. Generally, harvesting effects include changes in vegetation nutrient availability, soil microclimate/structure and litter quantity/ quality. Several studies were carried out on the impacts of heavy machines on the soil. However, only few studies took int...

Wilms tumor (WT) is an embryonal tumor occurring in developing kidney tissue. WT cells showing invasive cancer characteristics, also retain renal stem cell behaviours. In-vitro culture of WT is hampered by limited replicative potential. This study aimed to establish a longterm culture of WT cells to enable the study of molecular events to attempt to explain its cellular senescence. METHODS Pr...

BACKGROUND Mesenchymal stem cells (MSCs) from different sources have different characteristics. Moreover, MSCs are not isolated and characterized in Guinea pig for animal model of cell therapy. AIM OF THE WORK was the isolating of bone marrow MSCs (BM-MSCs) and adipose tissue MSCs (AT-MSCs) from Guinea pig and assessing their characteristics. MATERIAL AND METHODS In this study, bone marrow ...

Cytarabine (araC) is a highly active antimetabolite against hematological malignancy while the agent shows limited activity for some patients despite maintenance or continued therapy with ara-C-containing regiments. In this study, we focused to elucidate the mechanism of intrinsic resistance to araC. The concentration of intracellular ara-CTP and incorporated ara-CTP were monitored in human leu...

This study compared the effects of two annotation modalities on the reading comprehension of Iranian intermediate level EFL learners. The two experimental groups under study received treatment on 10 academic L2 reading passages under one of two conditions: One group received treatment on key words in the reading passages through a multimedia environment providing textual annotations. The second...
