Design Based Research (DBR) is a new and still-emerging approach to research about design, learning, and allied areas. This article reports one designer’s experiences within a DBR project. Whereas most reports of DBR focus on the outcomes of the design itself, the current paper offers a hermeneutical perspective by focusing on the personal narrative of the designer. Using Edelson’s (2002) categ...

The effect of 90 minute supine restraint or forced swim stress, on weights of various organs in sixty adult male albino rats was studied. One group of twenty rats served as control; second group of twenty was immobilized and third group of twenty was forced to swim in water at room temperature. The animals were studied for a period of 15 days. During this period, they were subjected to 90 minut...

introduction: different mechanisms are involved in stress induced analgesia (sia) and hyperalgesia (sih). repeated stress induces development of tolerance to sia. the role of hpa axis and gs signaling pathway in these effects are investigated in the current study. methods: forced swim stress (5 min/day) in water (20±1 ºc) was employed to adult male wistar rats (200-250 g). the nociceptive thres...

background: nephrotoxicity is one of the major side-effects of cisplatin that has been seen in about 20% of treated patients. the aim of this study was to assess the effectiveness of a forced hydration protocol comprised of isotonic saline, potassium chloride (kcl) and magnesium sulfate (mgso4) on prevention of cisplatin nephrotoxicity. methods: this cross sectional prospective study was perfor...

The effects of melatonin administered chronically on forced-swim test and open-field test behaviours were examined in male and female rats. The forced-swim test has been shown to be sensitive to all major classes of antidepressants and evidence indicates that melatonin possesses putative antidepressive properties. Male and female Long-Evans rats received either a regimen of chronic administrati...
