kamtal skarn is located 15 km northeast of kharvana, east-azarbaijan. a quartz-monzonitic stock of oligocene age intruded the upper cretaceous sedimentary sequence (claystone, limestone, marl, and siltstone) developing noticeable metamorphic (marble, hornfels) and metasomatic (skarn) alteration zones along the contact. kamtal skarn is of calcic type and consists of both endoskarn and exoskarn z...

Background and Objectives: Previous studies have indicated that lithium may increase the level of the brain-derived neurotrophic factor (BDNF), which in turn improves the recovery of patients with stroke. In this controlled trial we evaluated the effect of lithium on BDNF serum level in patients with ischemic stroke. Methods: In this randomized controlled...

  The effects of gentamicin, lithium and combination of these drugs on ultrastructural morphology of rat submandibular glands were studied. Daily intraperitoneal injection of 40 mg/kg of gentamicin which causes chronic salivary gland toxicity, led to a marked decrease in gland's dry weight and total protein concentration but did not affect DNA content. Electron micrograph (EM) of submandibular ...

Binary alkali silicate glasses were synthesized as beads by aerodynamic levitation coupled to laser heating test the applicability of method this compositional range. While bubble-free lithium disilicate could be easily obtained, sodium and potassium silicates proved more challenging melt without significant evaporation: final samples contained bubbles exhibited drifts compared starting stoichi...

The results of a study anodes obtained by carbonization silicon monoxide means reaction with solid-phase fluorocarbon CF0.8 are presented. Charge/discharge voltage profiles were studied at different currents depending on the composition and temperature synthesis composites. irreversible losses 1st cycle contribution to them intrinsic due formation lithium oxide its silicates associated SEI anal...

Autologous bone grafting remains the gold standard for bone grafting in clinical practice. Although it has withstood the test of time, it remains associated with multiple comorbidities. The search for an alternative bone graft substitute harnessing bone's osteoconductive, osteoinductive, and osteogenic properties remains a challenge. This article examines the various bone grafting materials cur...

Lithium is an element which has been used as salts of chloride or carbonate for many years in the treatment of some psychological disorders such as mania, bipolar or schizophrenic diseases. Chronic application of lithium may induce some serious nephropathies such as natriuresis, renal tubular acidosis, tubulointerstitial nephritis progression to progressive chronic kidney disease and hypercalce...
