Abstract:
Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease affecting the white matter of the brain. This condition is caused by the John Cunningham virus and leads to progressive neuropsychological deficits. Though the infection is typically seen in association with HIV or AIDS, other immune-compromised states may predispose patients as well. This report discusses a patient who developed PML following standard chemo-radiotherapy for non-small cell lung cancer in whom presentation was initially more convincing for brain metastasis; thus, highlighting the importance of accurate diagnosis of new brain lesions in this setting.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
