A fatty-acid based probe for near-infrared fluorescence guided surgery of glioblastoma

Elena Goun, Pavlo Khodakivskyi

High-grade gliomas (HGG) are the most common and most aggressive primary tumors of the brain. Despite recent advances in neuro-oncology survival of these tumors remains around 12-15 months. The first-line of treatment is surgical resection. However, due to ...

Brain matters: unveiling the distinct contributions of region, age, and sex to glia diversity and CNS function

Gioele La Manno, Zahra Moslehi, Nina-Lydia Kazakou

The myelinated white matter tracts of the central nervous system (CNS) are essential for fast transmission of electrical impulses and are often differentially affected in human neurodegenerative diseases across CNS region, age and sex. We hypothesize that ...
