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...

Rule-based models, which are typically formulated to represent cell signaling systems, can now be simulated via various network-free simulation methods. In a network-free method, reaction rates are calculated for rules that characterize molecular interactions, and these rule rates, which each correspond to the cumulative rate of all reactions implied by a rule, are used to perform a stochastic ...

OBJECTIVE Electroporation mediated transfer of plasmid DNA into peripheral muscle results in high transfection efficiency. The aim of this study was to investigate the effect of gene transfer of human IL-10 (hIL-10) into the tibialis anterior muscle (MTA) in combination with low dose Cyclosporine A (CsA) on acute rejection of lung allografts in the rat. METHODS Lung allotransplantation was pe...

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 ...

Solid state thermal neutron detectors are desirable for replacing the current He based technology, which has some limitations arising from stability, sensitivity to microphonics and the recent shortage of He. Our approach to designing such solid state detectors is based on the combined use of high aspect ratio silicon PIN pillars surrounded by B, the neutron converter material. To date, our hig...
