agrobacterium tumefaciens is capable to transfer genes across kingdoms. it can genetically transform not only plant cells, but also many other bacterial, algal, fungal, animal and human cells. this depends on the interactions among a variety of both agrobacterium and host genes. inside the host cell, rad52 which is involved in dna repair is a key gene determining integration of t-dna by homolog...

purpose: mesh technique is the standard for inguinal hernia repair because of less recurrence,   but it is inferior or equal to sutured technique in case of other post-operative complications   such as chronic pain. this clinical trial set out to compare these two techniques.   materials and methods: a total number of 322 cases of unilateral inguinal hernia in participants   older than 18 years...

introduction : although many techniques have been described for reconstruction of the giant omphalocele, we present a simple , effective and safe new technique. materials and methods: we have studied 11 neonates with giant omphalocele that were treated by a new technique, umbrella repair, in sarvar pediatric hospital of mashhad, iran. in this new technique we released the skin around the omphal...

objective: different ceramic repair systems have been reported for fractured ceramics. however, limited information is available concerning the bond strength of these systems especially after thermocycling. the aim of this in-vitro study was to determine the effect of thermocycling on the shear bond strength of composite-resin to feldspathic porcelain with and without silane pretreatment. mater...

statement of problem: in some clinical situations, repair of composite restorations is treatment of choice. improving the bond strength between one new and old composite usually requires increased surface roughness to promote mechanical interlocking since chemical bonding might not be adequate. similarly, the treatment of a laboratory fabricated resin composite restoration involves the same pro...

patients and methods previously recorded data of 231 patients who underwent surgical closure of vsd between january 2009 and january 2012 at the rajaie cardiovascular medical and research center were retrospectively reviewed. vsd surgical repair was performed using continues suturing technique in group a patients (n = 163, 70.6%) and interrupted suturing technique in group b patients (n = 68, 2...

the management of machine replacement (specifically tractors) is one of the most critical factors for performing field operations on time. therefore, tractor repair and maintenance costs must be accurately predicted. this research was carried out to evaluate the use of the regression technique in predicting tractor repair and maintenance costs. the study was conducted using empirical data on 60...

conclusions due to more sophisticated diagnostic tools and surgical approaches, mortality and morbidity of blunt aortic injuries were significantly reduced over the years compared to thoracic endovascular aortic repair and or over two different time periods. objectives the aim of the present study was to retrospectively evaluate the mortality and morbidity with either treatment option. therefor...

atrioventricular groove rupture is a rare, albeit mortal, complication following mitral valve surgery. avoidance is the best strategy but it cannot fully prevent the occurrence of this complication. several repair techniques have been described with varying success rates; however, the rarity of the complication precludes consensus about the safest technique. here we report two cases of posterio...
