purpose: to evaluate the effect of posterior residual stroma on visual function after unsuccessful anwar's deep anterior lamellar keratoplasty (dalk). methoods: in this parallel historical cohort, visual acuity and refractive status were evaluated after descemetic dalk (group 1) and compared with those of pre-descemetic dalk (group 2). results: one hundred and ten keratoconic eyes were enr...

Abstract Background Patients on hemodialysis (HD) have a high morbidity and mortality from cardiovascular disease (CVD). Despite advances in HD -new membranes, such as medium cut-off (MCO) or techniques that combine diffusion+convection+adsorption hemofiltration with ultrafiltrate regeneration- (HFR)-, only online hemodiafiltration (OL-HDF) has been shown to improve survival these patients. It ...

Common obstacles to successful retrieval of retrievable inferior vena cave filter include embedded filter hook and severe tilt of the filter. We described a modified wire-loop snare technique using self-made fishhook-like pigtail catheter and 11-F-long sheath to retrieve a severe tilted filter with embedded hook successfully. The modified wire-loop snare technique is simple and effective requir...

to investigate the effect of preprocessing techniques including contrast enhancement and illumination correction on retinal imagequality, a comparative study was carried out. we studied and implemented a few illumination correction and contrast enhancementtechniques on color retinal images to find out the best technique for optimum image enhancement. to compare and choose thebest illumination c...

The filter membrane in a CRRT extracorporeal circuit is vitally important for several reasons. Because it has the largest degree of exposure to blood of all circuit components, the membrane is the most important determinant of the circuit’s overall biocompatibility. In addition, membrane characteristics determine both the solute removal and water permeability properties of a CRRT filter. The fo...
