Antisense oligonucleotides as a targeted therapeutic approach in model of acute myeloid leukemia.

Background: The genetic and epigenetic alterations observed in acute myeloid leukemia (AML) contribute to its heterogeneity, influencing disease progression response to therapy, and patient outcomes. The use of antisense oligonucleotides (ASOs) technology allows for the design of oligonucleotide inhibitors based on gene sequence information alone, enabling precise targeting of key molecular pathways or specific genes implicated in AML.

Methods And Results: Midostaurin, a FLT3 specific inhibitor and ASOs targeting particular genes, exons, or mutations was conducted using AML models.

Insights into the molecular basis of gastric mucosa as a first step for using Raman microscopy in paediatrics.

Recent advances in endoscopic technology have allowed detailed observation of the gastric mucosa, including Raman microscopy and spectroscopy. To explore the possibilities for future diagnostic use, we discuss the measurements and molecular markers found in this tissue. The Raman spectra of 16 samples of antral mucosa and 16 samples of corpus gastric mucosa obtained from healthy donors were analysed.

Conformations and hydration of halopropionic acids studied by molecular dynamics and Raman optical activity.

Chiral 2-halopropionic acids and their derivatives were synthesized and their properties studied computationally using Raman and Raman optical activity (ROA) spectroscopy. For neat acids present as liquids small amount of water led to significant changes in the spectra, resulting even to flipping of some ROA band signs. We find this interesting for the role water plays in interpretation of vibrational optical activity spectra of biomolecules.

Pathophysiological and clinical point of view on Kawasaki disease and MIS-C.

This article compares two important pathophysiological states, Kawasaki disease, and multisystem inflammatory syndrome, in children associated with COVID-19 (MIS-C). Both occur predominantly in children, have a temporal association with an infectious agent, and are associated with immune-system alteration and systemic inflammation under certain circumstances. The two share common pathophysiology, including enhancement of interleukin-1 neutrophils, activation of the inflammasome, pyroptosis, or NETosis.
