Stearoyl-CoA desaturase (SCD) has recently been shown to be a critical control point of lipid partitioning and body weight regulation. Lack of SCD1 function significantly increases insulin sensitivity in skeletal muscles and corrects the hypometabolic phenotype of leptin-deficient ob/ob mice, indicating the direct antilipotoxic action of SCD1 deficiency. The mechanism underlying the metabolic e...

Commitment of hematopoietic stem cells to B lineage precursors and subsequent development of B lineage precursors into mature B cells is stringently controlled by stage-specific transcription factors. In this study, we used integrated genetic approaches and systematically determined the role of Sry-related high mobility group box (Sox) 4 and the underlying molecular mechanisms in early B-cell d...

this study was an attempt to investigate the comparative impact of two types of teaching approaches, namely content-based (cbi) and task-based (tblt) instruction on the reading comprehension of iranian efl learners. for this purpose, sixty intermediate students from a pool of eighty five students studying at a private language school were chosen using a piloted pet. the students were then rando...
