Recently published evidence has raised concerns about worse late mortality and increasing need for reintervention after off-pump coronary artery bypass grafting. We undertook this study to assess the impact of off-pump coronary artery bypass grafting on survival and freedom from reintervention at 10 years. From January 2002 to December 2002, 307 consecutive patients who had isolated multivessel...

The optimum management for recurrent glenohumeral instability with significant humeral head defects remains controversial. The purpose of this study was to compare outcomes and recurrence rates between patients who underwent osteochondral substitute grafting and patients who underwent remplissage to treat recurrent shoulder instability from an engaging Hill-Sachs defect with a Bankart lesion. T...

This study describes the preparation of a novel proton conducting membranes based on bacterial cellulose (BC) modified by grafting of 2-acrylamido-2-methyl-1 -propanesulfonic acid (AMPS) through UV-induced graft polymerization. These AMPS-g-BC membranes have been characterized by various techniques including FTIR, SEM and TGA, to find their successful grafting of AMPS on BC, surface morphology ...

Micro-grafting and mini-grafting trials were carried out in order to obtain complete Pinus patula plants generated vitro, derived from the fact that formation of roots micro-propagated shoots is very low or null. On other hand, there possibility generating clones with outstanding genetic characteristics. P. seeds established aseptic conditions geminated vitro DCR medium; aerial part was dissect...

acrylamide was grafted in low density polyethylene during melt processing in the presence of a free radical initiator using a torque rheometer in a closed system. effects of processing time, acrylamide and benzoyl peroxide concentrations were studied. ftir studies revealed that the degree of grafting increased by an increase in acrylamide concentration. maximum grafting was obtained at 7 minute...

BACKGROUND It has been previously shown that a persistent (up to 1 month) prothrombotic status occurs after coronary bypass surgery performed both on pump and off pump. To assess the pathways involved in the occurrence of postoperative prothrombotic state, in this study we evaluated plasma, monocyte-bound, and platelet-bound tissue factor expression, as well as platelet and soluble P-selectin e...

OBJECTIVE A systematic review of the effectiveness, safety, and applicability of autologous transplantation methods in vitiligo. DATA SOURCES Computerized searches of bibliographical databases, a complementary manual literature search, and contacts with researchers and pharmaceutical firms. STUDY SELECTION Predefined selection criteria were applied to all studies found. DATA EXTRACTION Tw...

Recent experimental and theoretical studies have demonstrated that relative to singly tethered chains, the presence of polymer loops at interfaces significantly improves interfacial properties such as adhesion, friction, and wettability. In the present study, a simple system was studied to examine the formation of polymeric loops on a solid surface, where the grafting of carboxylic acid termina...

Bone grafting has become an essential part of implant dentistry. Thanks to the advancement of grafting technology, areas that could only be managed with removable dentures or teeth-supported fixed prostheses can now be successfully treated with implant-supported prosthesis. Nonetheless, the complications associated with bone grafting procedures have slowly emerged to be one of the main challeng...

The objective of the current study is to evaluate and determine effect monomer concentration ClAETA on grafting copolymerization oxidized cellulose which isolated from peel durian. Four concentrations were used in this study, e.g., 40, 50, 60, 70%. Several analyses performed material characteristic, degree grafting, FT-IR, surface morphology, contact angle, swelling, antibacterial activity. res...
