workers are called, are all voluntary and committed to give up to two years of their life to this work. They get ?1 a week pocket money, two ounces of tobacco and board and lodging, none too luxurious, for the privilege of joining this 'Mission to the Misfit.' They raise money by running an old clothes stall, beg for food, pick up fruit and vegetables that fall off trucks and trolleys in Covent...

Introduction: The purpose of this study was to determine Na-Ca exchanger 2, 3 (NCX2, 3) protein level changes during 2, 5, 10, 15 days after induction of normobaric hyperoxia (HO) preconditioning. Materials and Methods: Rats were divided in two experimental groups. The first group was exposed to 95% inspired HO for 4 h/day for 6 consecutive days (HO). The second group acted as control, and was...

This paper performs an assessment of tourists' perception towards semces associated with lodging (hotel factors), dining (restaurant factors), and transportation (transportation factors). The results of the empirical analysis suggested that these are the underlying dimentions held by the tourists: (1) Hotel factors Staff service quality, room quality, business serVices,. security, value and foo...

like other economic markets, housing market is comprised of supply and demand dimensions and equality of supply and demand makes the housing market balanced. the aim of this paper is to investigate the characteristics of housing market of tehran city and some deficiencies of this market with fundamental – applied methodology. the variable studied here is the saleable residential unit with minim...

  Introduction: Using beta emitter radionuclide is a useful therapeutic modality in the treatment of skin cancers in areas which are difficult to cure by other methods. The aim of this research is to evaluate the tissue response to beta rays of 166Ho and determine the feasibility of beta emitting radionuclide for treatment of skin cancers. Methods: In this...

Introduction: Recently, 166Ho-BPAMD was introduced as a suitable agent for bone marrow ablation. The aim of this study was to estimate the absorbed dose of this novel agent in the human organs which is necessary before the clinical application. Methods: 166Ho was produced by direct irradiation of 165Ho in the research reactor. 250 µg...

Water scarcity and salinity are important limitations for saffron (Crocus sativus L.) production in arid and semi-arid regions. The purpose of this research was to study the interaction effects of water salinity and deficit irrigation on the macroscopic water extraction model for saffron. The effect of salinity and water stress on root-water uptake coefficient was determined by additive and mul...

Introduction: Ischemic preconditioning (IPC) is an endogenous phenomenon that can induce ischemic tolerance (IT) in variety of organs such as brain. In this study, we examined the intermittent and prolonged dose of normobaric hyperoxia (HO) on neurologic deficit scores, infarct volume, and catalase activity. Material and Method: The rats were divided to four main groups. First two main groups w...

Recently we reported on the presence of two isoforms of heme oxygenase in rat liver microsomes, referred to as HO-1 and HO-2, and that only HO-1 is inducible (Maines, M. D., Trakshel, G. M., and Kutty, R. K. (1986) J. Biol. Chem. 261, 411-419). Presently we report on the detection of two isoforms of the enzyme in rat testis and purification to near homogeneity of the noninducible isoform, HO-2....

Heme oxygenase-1 (HO-1) and -2 play an important role in cytoprotection and are physiologic regulators of heme-dependent protein synthesis in renal tissues. The impact of HO-2 deletion comparing hyperglycemic HO-2 (+/+) mice and HO-2 knockout (-/-) mice was examined. Hyperglycemia was induced by streptozotocin (STZ) injection, and its effect on renal HO-1/HO-2 protein, HO activity, and creatini...
