We present measurements of the cosmic ray positron fraction from 4.5 { 50 GeV obtained from the rst balloon ight of the High Energy Antimatter Telescope (HEAT). A superconducting magnet spectrometer combined with a transition radiation detector, an electromagnetic calorimeter, and time-of-ight counters were used to achieve powerful hadron rejection at these energies. We see no evidence for the ...

The anti-tumor activity of Morinda citrifolia fruit juice (Noni) has been previously reported. However, the mechanism behind this activity remains unknown. In the present study, we studied the anti-tumor activity of fermented Noni exudate (fNE) and demonstrated that intraperitoneal injection of this material significantly increased the percentages of granulocytes and NK cells in the peripheral ...

introduction: due to its immunosuppressive properties, local graft irradiation (lgi) has been proposed as a second line therapy for treatment of acute kidney rejection. case presentation: in this case-series we report 6 patients with biopsy proven acute kidney allograft rejection refractory to conventional antirejection therapy who underwent lgi for treatment of acute rejection at our center. t...

introduction epithelial rejection typically begins in a linear pattern from the periphery of the graft and progresses centripetally. here in, we reported a patient with a new presentation of corneal epithelial graft rejection. case presentation a 23-year-old man presented with blurred vision two months after penetrating keratoplasty. conclusions slit lamp examination revealed sharply demarcated...

In this paper, the removal of phenol by using aqueous solution in a low pressure reverse osmosis membrane was investigated. The effect of feed pressure, feed concentration, feed flow rate and feed pH on phenol rejection was investigated. The results showed that feed pH is the most affective parameter on the phenol rejection. Rejection of phenol increased with increasing pH from 2 to 10 under th...

dendritic cells (dcs) are a heterogeneous family of professional apcs involved in priming adaptive immune responses. donor dcs (direct pathway of allorecognition) and recipient dcs presenting processed donor major histocompatibility complex (mhc) as peptides (indirect pathway of allorecognition) participate actively in graft rejection by stimulating recipient t cell responses following organ tr...

conclusions patients’ experiences of stigma and rejection phenomena indicated that all aspects of their lives are affected. moreover, these findings highlight the significance of stigma and rejection concepts in providing better care to these patients. results after analysis of interviews, four themes were extracted: lack of social support, unrealistic and inappropriate labeling, rejection and ...
