introduction the avan cu-fe skarn is located at the southern margin of qaradagh batholith, about 60 km north of tabriz. the skarn-type metasomatic alteration is the result of qaradagh batholith intrusion into the upper cretaceous impure carbonates. the studied area belongs to the central iranian structural zone. in regional scale, the studied area is a part of the zangezour mineralization zone ...

Drosophila eye pigmentation defects have thus far been attributed to mutations in genes encoding enzymes required for biosynthesis of pigments and to ABC-type membrane transporters for pigments or their precursors. We report here that a defect in a gene encoding a putative coat adaptor protein leads to the eye color defect of garnet mutants. We first identified a human cDNA encoding delta-adapt...

Laser therapy has the potential to be an effective, minimally invasive procedure in periodontal therapy. The aim of the present review was to survey the relevant literature on the clinical application of lasers as a minimally invasive treatment for periodontitis and peri-implant disease. Currently, there are a large number of published clinical studies and case reports that evaluate the adjunct...

BACKGROUND Laser therapies have been Food and Drug Administration approved for temporary nail plate clearance; however, there is minimal evidence of their long-term efficacy. OBJECTIVE We sought to evaluate the clinical and mycological clearance of toenails treated with 1064-nm neodymium:yttrium-aluminum-garnet laser versus no treatment. METHODS This was a randomized, controlled, single-cen...

Using a reflection magneto-optic technique we have investigated natural inhomogeneities and artificial struetures in YBCO thin films exposed to an external magnetic field. The artificial structures were mechanically scratched by scanning a diamond tip with different loading over the film, surface. AIternatively planar structures with reduced oxygen content could be patterned by heating the YBCO...

Both highand medium-pressure granulites have been found as because of the absence of modal minerals. The combination of petrographic textures, mineral compositions, metamorphic reaction enclaves and boudins in tonalitic–trondhjemitic–granodioritic gneisses in the Hengshan Complex. Petrological evidence from these history, petrogenetic grids and thermobarometric data defines a nearrocks indicate...

OBJECTIVE To evaluate the efficacy of transmyocardial revascularization performed on patients with refractory class IV or unstable angina with a holmium:yttrium-aluminum-garnet laser. METHODS Transmyocardial revascularization with a holmium:yttrium-aluminum-garnet laser was performed in 42 patients with refractory angina who were not candidates for percutaneous transluminal coronary angioplas...
