A 31-year-old female admitted with productive cough and progressively increasing edema in her legs. Four years ago she had the diagnosis of situs inversus (SI) totalis. She had6.5 g/day proteinuria in 24-hour urine analysis. High resolution computed tomography revealed bronchiectatic areas in the left lung. In renal biopsy, kongo and amyloid AA antibody positivity was detected in arteriolar walls and mesangial areas. The patient is currently being followed with ramipril and colchicine treatments. Primary ciliary dyskinesia (PCD) and resultant SI totalis are very rare anomalies characterized by the total inversion of all organs and chronic bronchiectasis. There are very few reports on the association of SI totalis with nephrotic syndrome. Patients with SI totalis and chronic bronchiectasis have increased risk of AA amyloidosis and possibly end stage renal disease and thus these patients should be regularly followed with proteinuria and serum creatinine levels.

The effect of the valence band tail width on the open circuit voltage of P3HT：PCBM bulk heterojunction solar cell is investigated by using the AMPS-1D computer program. An effective medium model with exponential valence and conduction band tail states is used to simulate the photovoltaic cell. The simulation result shows that the open circuit voltage depends Iinearly on the logarithm of the generation rate and the slope depends on the width of the valence band tail. The open circuit voltage decreases with the increasing width of the band tail. The dark and light ideality factors increase with the width of the valence band tail.
