purpose: to compare the short and long-term efficacy and complications of releasable suture vs conventional interrupted suture for scleral flap in trabeculectomy. methods: in a prospective randomized clinical trial, 42 eyes of 42 consecutive patients requiring trabeculectomy for uncontrolled primary glaucoma underwent conventional trabeculectomy (group a) and trabeculectomy with releasable sutu...

closure of donor site of the flap has special problems. reduction of this site will decrease the morbidity of operation. in this study, we present our experience in donor site size reduction. methods between 2006 and 2008, 15 patients with skin and soft tissue defects underwent operation. in all patients, coverage of defect was performed with various flaps. substratum horizontal mat-tress sutur...

Tectonic interpretations of arc remnants in the Himalayan orogen remain uncertain, despite their important implications for overall convergence history between India and Eurasia. Provenance results from deep-water volcaniclastic rocks Indus Suture Zone Ladakh provide new constraints on Mesozoic tectonic evolution Dras Kohistan-Ladakh arcs. Detrital zircon (DZ) U-Pb ages whole-rock geochemistry ...

Both the Sistan Suture Zone of eastern Iran and the Nehbandan Fault contain Plio-Quaternary Nehbandan mafic lavas. Positive anomalies in the large ion lithophile elements (LILE) and negative anomalies in Nb (niobium) exist in these mafic lavas. This indicates the occurrence of subduction magmatism and post-collision volcanism. Petrologic and geochemical analyses distinguished two groups of lava...

OBJECTIVE The effects of chronic coronary occlusion on the capillarity of left ventricular tissue in rat heart. METHODS The heart was exposed through a left-sided thoracotomy in ethylether-anesthetized and ventilated rats. The left coronary artery was occluded with a thin suture and the thorax was closed. Thirty days after the surgery the heart was removed and cross-sections were made for mor...

The paleoelevation history and geodynamic evolution of the Bangong suture zone in central Tibetan Plateau are hotly debated, with existing estimates showing contrasting results. Acknowledging complexity hydrologic processes continental interiors, we first demonstrate that stable isotope-based paleoaltimetry, necessary adjustment to account for moisture mixing, is applicable Central Tibet. We us...
