Background: Human cornea expresses functional Fas-ligand capable of killing Fas+ activated lymphocytes. Fas expression is partly regulated by -670 A/G polymorphism in the promoter region of Fas gene. Objective: The aim of the present study is to determine the association between Fas-670A/G polymorphism and survival of corneal transplantation. Methods: In 276 graft recipients who mainly underwen...

This study proposes a patch antenna with an H-shaped slot direct matching and harmonic tuning (rejection) functions for microwave power transfer. enables integrated active in which the amplifier are directly connected without using circuit fundamental frequency rejection filter to improve efficiency of amplifier. The design also reduces total size antenna, allowing higher-density array antenna....

We analyze the resonant transmission of two near-field coupled, cascaded bandpass filters, based on metallic stripe or patch gratings. The response, in terms both maximum efficiency and light rejection out resonance, overpasses simple convolution responses isolated while keeping good angular tolerance. Illustrations are given infrared visible ranges where technological integration such compact ...

Rejection sensitivity is the heightened tendency to perceive or anxiously expect disengagement from others during social interaction. There has been a recent wave of neuroimaging studies of rejection. The aim of the current review was to determine key brain regions involved in social rejection by selectively reviewing neuroimaging studies that employed one of three paradigms of social rejection...

background: in addition to human leukocyte antigens (hla) compatibility, gene polymorphisms in cytokines might also be important in the quality of allogeneic immune response. objective: to evaluate the influence of hla-dr matching and a number of cytokine gene polymorphisms on acute rejection after living-unrelated donor (lurd) kidney transplantation. methods: a total of 42 renal transplants pe...

background and aim the most common complication of renal transplantation is allograft dysfunction, which in some cases leads to graft loss. the role of graft nephrectomy in the management of transplant failure is controversial. the procedure remains associated with a significant morbidity and also mortality. our main purpose was the comparison between clinical and pathological diagnosis of graf...

Social rejection can increase aggression, especially among people high in rejection sensitivity. Rejection impairs self-control, and deficits in self-control often result in aggression. A dose of glucose can counteract the effect of situational factors that undermine self-control. But no research has integrated these literatures to understand why rejection increases aggression, and how to reduc...
