Dual-Functional Manganese-Doped ZnO-MOF Hybrid Material with Enhanced Hydrolytic Stability: A Fluorescent Photoinduced Electron Transfer Sensor for the Ultraselective Detection of Acetic Acid and Chromium (VI).

In recent years, the synthesis of metal-organic framework (MOF)─nanocomposites has received wide attention from the scientific fraternity due to the presence of a tunable hierarchical architecture and invasive versatility in applications. The present work focuses on the solvothermal synthesis of a novel hybrid MOF-nanocomposite through the impregnation of Mn-doped ZnO nanoparticles onto the matrix of a pioneer metal-organic framework that is composed of zinc metal connected with terephthalic acid linkers (MOF-5). The hierarchical arrangements of the prepared material were further assessed by Fourier-transform infrared spectroscopy (FTIR), powder X-ray diffraction (PXRD), high-resolution transmission electron microscopy (HR-TEM), UV-visible, photoluminescence (PL), and dynamic light scattering (DLS) measurements.

A rare simultaneous presentation of combined occlusion and optic neuritis in a lupus erythematosus patient with anti-phospholipid antibody syndrome.

Background: A known case of Systemic Lupus Erythematosus (SLE) developed sudden loss of vision (no light perception) with relative afferent pupillary defect in her right eye (RE) and fundus examination revealed cherry red spot over tomato splash background with tortuous and dilated veins suggestive of combined central retinal arterial and vein occlusion.

Analysis: Left eye (LE) had 6/6 vision but posterior segment revealed a hyperemic disc. Fundus fluorescein angiography (FFA) revealed delayed arm to retina time and increased arterial to vein transit time in RE.
