Green Synthesis of MnO Nanoparticles Using Leaf Extract for Biological, Photocatalytic, and Adsorption Activities.

We report the synthesis of MnO nanoparticles (AI-MnO NAPs) using biological molecules of leaf extract. Further, they were evaluated for antibacterial and cytotoxicity activity against different pathogenic microbes (, , , and ) and HeLa cancerous cells. Synthesized NAPs were also investigated for photocatalytic dye degradation potential against methylene blue (MB), and adsorption activity against Cr(VI) was also determined.

Mediastinal seminoma presenting as superior vena cava syndrome and tracheal obstruction.

Malignant germ cell tumours of the mediastinum are rare, presenting mostly in young males. These are bulky tumours, mostly intrathoracic, infiltrating into adjacent structures early in the growth process. Patients may present with symptoms of compression.
