The dynamic interactions of an individual matrix metalloproteinase-1 were imaged and monitored in the presence of either triple-helical or non-triple-helical, partially structured collagen-mimic substrates. The enzyme exhibited ten-fold increased catalytic turnover rates with the structurally modified substrate by skipping the triple-helix unwinding step during the catalytic pathway.

Purpose: The rapid rise in smartphone use has led to declining sleep quality. Excessive internet use has been linked to negative impacts on physical and mental health, and individual personality traits (PT) may contribute to internet addiction and mitigate its harmful effects. This study aims to: (1) examine whether PT mediate the relationship between smartphone use and sleep quality, and (2) investigate whether the relationship between smartphone use and sleep quality varies across different gender and age groups.

Background: Alzheimer's Disease and Related dementias (ADRD) are disproportionately underdiagnosed, misdiagnosed, and undertreated in Latino/a/e/x populations living in the U.S. Latino/a/e/x families also experience low access to ADRD caregiver support services and high levels of depression.

Background: Flecainide and other class-Ic antiarrhythmic drugs (AADs) are widely used in Andersen-Tawil syndrome type 1 (ATS1) patients. However, class-Ic drugs might be proarrhythmic in some cases. We investigated the molecular mechanisms of class-I AADs proarrhythmia and whether they might increase the risk of death in ATS1 patients with structurally normal hearts.

The ultrashort peptide -fluorenylmethoxycarbonyl-phenylalanyl-phenylalanine (FmocFF) has been largely investigated due to its ability to self-assemble into fibrils (100 nm-μm scale) that can form a sample-spanning gel network. The initiation of the gelation process requires either a solvent switch (water added to dimethyl sulfoxide) or a pH-switch (alkaline to neutral) protocol, both of which ensure the solubility of the peptide as a necessary step preceding gelation. While the respective gel phases are well understood in structural and material characteristics terms the pregelation conditions are known to a lesser extent.

Previously, we found that retinas of young male mice were more damaged than those of young female mice in the sodium iodate (NaIO) model. The purpose of this study was to test whether reducing testosterone levels would be retina-protective. Male C57Bl/6J mice underwent surgical castration or sham surgery, then were given an intraperitoneal injection of NaIO at 25 mg/kg.
