Silver antimonate, AgSbO3, in both its defective pyrochlore and ilmenite structural polymorphs, has been suggested as a possible candidate mixed metal oxide for use in the photocatalytic splitting of water in visible light. In this study, we report electronic-structure calculations, using both standard and hybrid density-functional-theory approaches, on both structural forms of AgSbO3 to fully ...

This research paper emphasized on application of Judd-Ofelt's (JO) theory for low doped erbium (0.2 mol%) halogeno-antimonate based glasses with molar composition (90 –x) Sb2O3 - x ZnBr2 10 NaCl (where = 10, 20, 30 and 40 mol%). 80 – 9.8 0.2 Er2O3 glass sample has phonon energy high refractive index is a potential candidate luminescence applications. Differential scanning calorimetry (DSC) meas...

visceral leishmaniasis is the second most common cause of fever of unknown origin in our study. this disease is not common in adults, although it's endemic among the pediatric age group. the majority of the affected individuals were young. high grade spiking fever, chills and splenomegaly were unique findings. other common findings were neutropenia, anemia, abnormal liver function tests, s...

Three secondary metabolites isolated from Chilean lichens, (+) usnic acid, pannarine and 1'-chloropannarine, were tested against promastigotes forms of three strains of Leishmania ssp. Pannarine and 1'-chloropannarine exhibited in vitro activity at 50 micrograms/ml and (+) usnic acid at 25 micrograms/ml. BALB/c mice infected with Leishmania amazonensis were treated 4 weeks post-infection with (...

The intracellular localization of calcium during contraction of striated flagellar roots of the green alga Tetraselmis subcordiformis was investigated using calcium pyroantimonate and calcium oxalate cytochemistry and energy-dispersive X-ray microanalysis. Vesicles (0.25 - 0.50 microns diameter) located in the anterior-most region of the cell are calcium-sequestering organelles. These vesicles ...

Old world cutaneous leishmaniasis (OWCL) usually causes a single, self-healing and uncomplicated lesion mainly on the exposed area of body. This report presents four cases of OWCL from Iran that misdiagnosed with sarcoidosis, lymphoma, and acne agminata. Two out of four patients showed a history of purplish red plaques for at least 5 years who misdiagnosed as sarcoidosis because of histological...
