Unilateral buried optic nerve head drusen triggering central retinal vein occlusion in young – Discovering an eclipsed entity

Optic nerve head (ONH) drusen are acellular calcified concretions. Buried drusen manifests as pseudopapilledema. The compressive effects of ONH drusen can rarely precipitate central retinal vein occlusion (CRVO). The superimposition of pseudopapilledema on disc edema in CRVO poses a diagnostic dilemma. A 40-year-old female without systemic comorbidities presented with resolving CRVO. An exhaustive systemic workup revealed no abnormalities. Ultrasonography demonstrated buried ONH drusen. This unusual etiology must be considered in a young patient in the absence of systemic risk factors, persistence of “nasally conspicuous” disc elevation, and presence of peripapillary hemorrhages. Ultrasonography must be incorporated in the diagnostic armamentarium in a young patient with CRVO

Superb catalytic activity of as-green synthesized copper ferrite's thermal decomposition of ammonium perchlorate

A simple one step method is employed for the synthesis of CuFe2O4 nanoparticles (NPs) aided by utilizing egg albumin (EA) and aloe vera (AV) as solvents. The samples were characterized using X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM), Thermo Gravimetric/Differential Thermal Anaysis (TG/DTA), Vibration Sample Magnetometer (VSM) and X-ray Photolectron Spectroscopy (XPS). XRD analysis of the samples sowed the presence of CuFe2O4 and CuO in the samples. The ambient VSM study proved the ferrimagnetism behavior of the CuFe2O4. TG/DTA was used to study the catalytic activity of the CuFe2O4 nanoparticles, the results revealed that a 78 °C reduction in the decomposition temperature of Ammonium Perchlorate (AP) was achieved while using 6% CuFe2O4 prepared using a mixed EA-AV and calcinated at 700 °C. Hence, CuFe2O4 can be potent catalytic agent in several environmental applications as an efficient catalyst
