INTRODUCTION Different types of grafts have been described in urethral reconstruction (UR), with penile skin graft (PSG) and buccal mucosa graft (BMG) as the most frequently used ones. It still remains unclear whether one graft is superior in terms of success when compared to the other. MATERIAL AND METHODS A systematic review of the literature was performed searching the MEDLINE database wit...

Many investigators use bone matrix gelatin for bone induction but it is used rarely for repair of teeth defects. This study was designed to evaluate secondary dentin formation by endochondral bone matrix gelatin (E-BMG) in rabbit. E-BMG was prepared from tibia and femur of 4 Deutsche-Poland rabbits with average ages of 4-6 months. The prepared E-BMG was implanted in right incisor teeth pulps of...

abstract basement membrane of glomerular mesangium (bmg) is a thin membrane which helps to support the capillary loops in a renal glomerulus and type iv collagen is require for complete bm formation during glomerulogenesis. in this investigation specific antibody of type iv collagen has been used in light microscopy to study development of bmg of the embryonic and postnatal mouse glomerular mes...

AIM to compare long term follow-up between end-to-end urethroplasty and bucal mucosal graft for the management of patients with short bulbar urethral stricture. METHODS we conducted a meta-analysis of cohort studies. Literature research was performed on the MEDLINE, Science Direct, and EMBASE database including studies from 1980 through 2014. The inclusion criteria were patients with short bu...

The quantitative model proposed here for nanoimprinting by thermoplastic compression molding is focused on bulk metallic glasses (BMGs), but it is also applicable to polymers and other thermoplastic materials. In our model the flow and pressure fields are evaluated using the lubrication theory, and the effect of molding pressure, BMG viscosity, and capillary pressure on the spatial distribution...

Background: Repair of bone defects is challenging for reconstructive and orthopedic surgeons. In this study, we aimedto histomorphometrically assess new bone formation in tibial bone defects filled with octacalcium phosphate (OCP),bone matrix gelatin (BMG), and a combination of both.Methods: A total of 96 male Sprague Dawley rats aged 6-8 weeks weighing 120-150 g were randomly allocatedinto thr...

Demineralized bone matrix gelatin (BMG) was implanted into the skeletal muscle of Sprague-Dawley rats, and the resulting ultrastructural changes of the BMG were examined 3, 5, 7, 10, 15 and 20 days later. Most of the implanted BMG became calcified 7-20 days after implantation. Calcification ('acellular mineral deposition') was first observed as needle-shaped crystalline deposits in the BMG matr...

The high manufacturing cost for metallic glasses hampers actual commercial applications of this class of fascinating materials. In this letter, the effect of oxygen impurity on the glass forming ability and tensile properties of Zr-BMG composites were studied. Our results have demonstrated that oxygen was absorbed and concentrated only in the precipitated β-Zr phase, leading that the remainder ...

The number of processors embedded in high performance computing platforms is growing daily to solve larger and more complex problems. The logical network topologies must also support the high degree of scalability in dynamic environments. This paper presents a scalable and fault tolerant topology called binomial graph (BMG). BMG provides desirable topological properties in terms of both scalabi...

Recently, CuZr-based bulk metallic glass (BMG) composites reinforced by the TRIP (transformation-induced plasticity) effect have been explored in attempt to accomplish an optimal of trade-off between strength and ductility. However, the design of such BMG composites with advanced mechanical properties still remains a big challenge for materials engineering. In this work, we proposed a technique...
