PURPOSE The origin of autofluorescence in the subretinal space and the autofluorescence properties of the cells were investigated in surgically collected subretinal fluid. METHODS Subretinal fluid was surgically collected from four eyes of patients with rhegmatogenous retinal detachment (three eyes) and Coats' disease (one eye). After cytocentrifuge preparation of the cells in the fluid and i...

Serpentinization, i.e. the hydrothermal alteration of ultramafic rocks, is an important and ubiquitous geologic process that occurs at slow- ultraslow-spreading mid-ocean ridges, magma-poor passive margins, subduction zones. While serpentinization over a wide temperature range involves diverse fluid compositions, few experimental studies systematically examined effects composition on kinetics o...

Sar-Kuh porphyry copper deposit is located 6 km southwest of the Sar-Cheshmeh copper mine, Kerman Province, Iran. Based on field geology, petrography and fluid inclusions studies, four alteration types have been identified in the Sar-Kuh area. Early hydrothermal alteration formed a potassic zone in the central parts of Mamzar granite/grano-diorite stock and propylitic alteration in its peripher...

Abstract Primary fluid inclusions in bedded halite from the 830-m.y.-old Browne Formation of central Australia contain organic solids and liquids, as documented with transmitted light ultraviolet–visible (UV-vis) petrography. These objects are consistent size, shape, fluorescent response cells prokaryotes eukaryotes compounds. This discovery shows that microorganisms saline depositional environ...
