Differential Effect of Simulated Microgravity on the Cellular Uptake of Small Molecules.

The space environment can affect the function of all physiological systems, including the properties of cell membranes. Our goal in this study was to explore the effect of simulated microgravity (SMG) on the cellular uptake of small molecules based on reported microgravity-induced changes in membrane properties. SMG was applied to cultured cells using a random-positioning machine for up to three hours.

A Facile Synthesis of Red-Shifted Bis-Quinoline (BisQ) Surrogate Base.

Forced intercalation peptide nucleic acids (FIT-PNAs) are DNA mimics that act as RNA sensors. The sensing event occurs due to sequence-specific RNA hybridization, leading to a substantial increase in fluorescence. The fluorophore in the FIT-PNA is termed a surrogate base.

Detecting the lncRNA in Ovarian Cancer with Cyclopentane-Modified FIT-PNAs (cpFIT-PNAs).

Ovarian cancer (OC) is one of the most lethal gynecologic cancers that is typically diagnosed at the very late stage of disease progression. Thus, there is an unmet need to develop diagnostic probes for early detection of OC. One approach may rely on RNA as a molecular biomarker.

A Biotinylated cpFIT-PNA Platform for the Facile Detection of Drug Resistance to Artemisinin in .

The evolution of drug resistance to many antimalarial drugs in the lethal strain of malaria () has been a great concern over the past 50 years. Among these drugs, artemisinin has become less effective for treating malaria. Indeed, several variants have become resistant to this drug, as elucidated by specific mutations in the pfK13 gene.
