Objective: Benign migratory glossitis is a immunologic-psychologic disease with unknown etiology.Aim of this study is evaluation of salivary IL-1 and Il-8 levels in these patients. Study Design: A case-control study was performed on 170 participants (85 with BMG, 85 controls). Unstimulated whole saliva was collected, and interleukin 8 (IL-8) and interleukin 1(IL-1) concentrations were measured....

As two important mechanical properties, strength and ductility generally tend to be muturally exclusive in conventional engineering materials. The breakthrough of such a trade-off has been potentiated by the recently developed CuZr-based bulk metallic glass (BMG) composites ductilized by a shape memory CuZr(B2) phase. Here the microstructural dependences of tensile properties for the CuZr-based...

We present results of a series of plate-impact experiments conducted to understand spall threshold in a zirconium-based bulk metallic glass (BMG), Zr41.25Ti13.75Ni10Cu12.5Be22.5, following normal shock-induced compression and combined compression-and-shear loading. The experiments were conducted using a 82.5 mm bore single-stage gas-gun. A multibeam VALYN VISAR was used to measure the particle–...

A Zr55Cu30Ni5Al10 plate-like bulk metallic glass (BMG) was prepared using copper mold suction casting. Additionally, alloy powders with the same nominal composition were synthesized. The alloy powders were welded or melted to the cleaned surface of the BMG with a laser beam acceleration voltage of 60 kV, a beam current range from 60 to 100 mA, a welding speed of 60 mm/s, as well as an impulse w...

Peri-urban ecosystems are often managed as recreation areas or to enhance aesthetic value on the urban fringe. Scholars and land-use practitioners lack a current understanding of the supply of and the demands for these peri-urban ecosystem services (ES). In this study, we analysed the perceptions of 500 users and interest groups regarding the ES provided by the Bilbao Metropolitan Greenbelt (BM...

Intervertebral disc (IVD) degeneration is the major cause of lower back pain, while the currently available treatments are symptomatic rather than curative. Tissue engineering is a powerful therapeutic strategy that can restore the normal biomechanical motion of the human spine. The ability of a biphasic elastic scaffold to structurally and elastically simulate the annulus fibrosus (AF) tissue ...

BACKGROUND Our objective was to study tongue lesions and their significance in psoriatic patients. METHODS The oral mucosa was examined in 200 psoriatic patients presenting to Razi Hospital in Tehran, Iran, and 200 matched controls. RESULTS Fissured tongue (FT) and benign migratory glossitis (BMG) were the two most frequent findings. FT was seen more frequently in psoriatic patients (n = 66...

introduction: this investigation was done to examine the influence of bone matrix gelatin on bone induction in wnz male rabbit. materials and methods: the rabbits were purchased from razi institute and bone matrix gelatin (bmg) was prepared from the long bones according to m.urist method. using a dentistry drill, a hole with 3.5mm diameter was made at a distance of 2.5cm below the tibial medial...

Monolithic bulk metallic glasses (BMGs) exhibit a unique combination of mechanical properties, such as high strength and large elasticity limits, but the lack of ductility is considered the main Achilles’ heel of BMG systems. To increase the competitiveness of BMGs vis-à-vis conventional structural materials, the problem of catastrophic failure via intense plastic strain localization (‘shear ba...

Theories on the relationship between money and inflation had largely been shaped around the positive relationship and money causality for inflation before the Post-Keynesians. Since the 1980s, this idea emerged that there might be no correlation between money growth and inflation. In the case of existence, the causality is reversed, so money is endogenous somehow. However, practically there is ...
