Comparison of PET/CT and PET/MRI in central nervous system tumors, a narrative review.

Background: PET/CT and PET/MRI are two useful imaging modalities in neuro-oncology. Our aim was to review the existing literature on the benefits and drawbacks of using PET/CT and PET/MRI in the diagnosis of central nervous system (CNS) tumors.

Methods: A literature search was conducted using valid databases, limited to English-language articles published between 2010 and 2023, and independently reviewed by two reviewers.

Exploring the seas for cancer cures: the promise of marine-derived bioactive peptide.

Marine environments harbor a wealth of bioactive peptides with potential anticancer properties, sourced from diverse organisms like tunicates, sea sponges, and mollusks. Through isolation, identification, and modification, peptides such as Stylisin and Papuamides have shown enhanced activity and progressed to clinical trials, underscoring their therapeutic promise. Enzymatic hydrolysis emerges as a favored method for peptide extraction from marine proteins, with sponges identified as particularly rich sources.

Density functional theory and molecular dynamics simulation of water molecules confined between two-dimensional graphene oxide surfaces.

In this work, the interaction potentials of water molecule with the two-dimensional graphene oxide (GO) surfaces containing epoxy groups have been determined using the M06-2X/6-31g (d,p) level of theory at different orientations and separations and fitted to the Born-Huggins-Meyer (BHM) potential. Good agreements were found between the computed and the well-known OPLS-AA and Dreiding potentials. We have also used some calculated potentials and the well-known models in the molecular dynamics (MD) simulations.
