purpose: to assess the efficacy and safety of laser in situ keratomileusis (lasik) for correction of residual myopia and astigmatism after penetrating keratoplasty (pk). methods: in this prospective interventional case series, lasik was performed on 14 eyes of 13 patients unable to wear glasses or contact lenses after pk. the interval between lasik and pk was at least one year. all patients had...

Endothelial dysfunction which is manifested by the loss of nitric oxide bioavailability, is an increasingly recognized cause of cardiac syndrome X (CSX) and beta blockers are used for the treatment of this syndrome. Thus, the aim of this study was to investigate effects of metoprolol, as a beta blocker, on endothelial function in CSX patients. The study included 25 CSX patients (20 female/ 5 ma...

SUMMARY: Posterior reversible encephalopathy syndrome (PRES) is a neurotoxic state accompanied by unique brain imaging pattern typically associated with number of complex clinical conditions including: preeclampsia/eclampsia, allogeneic bone marrow transplantation, solid organ autoimmune diseases and high dose cancer chemotherapy. The mechanism behind the developing vasogenic edema CT or...

Objectives: Vascularization is an important stage for tissues and organs. The vascular network succeeded by the attachment, spreading, proliferation of endothelial cells, completion endothelialization. Endothelization can be mediated laminin-derived peptides on microtissues. It known that Tyr-Ile-Gly-Ser-Arg (YIGSR) peptide contributes to microtissue formation promoting increased adhesion cells...
