Dual Ionic Signal Detection: Modulation of Surface Charge of Nanofluidic Iontronics by Dual-Split Gate Voltages.

Nanofluidic iontronics, including the field-effect ionic diode (FE-ID) and field-effect ionic transistor (FE-IT), represent emerging nanofluidic logic devices that have been employed in sensitive analyses. Making analyte recognitions in predefined nanofluidic devices has been verified to improve the sensitivity and selectivity using a single ionic signal, such as ionic current amplification, rectification, and Coulomb blockade. However, the detection of analytes in complex systems generally necessitates more diverse signals beyond just ionic currents.

Aptazyme-directed A-to-I RNA editing.

As a promising therapeutic approach, the RNA editing process can correct pathogenic mutations and is reversible and tunable, without permanently altering the genome. RNA editing mediated by human ADAR proteins offers unique advantages, including high specificity and low immunogenicity. Compared to CRISPR-based gene editing techniques, RNA editing events are temporary, which can reduce the risk of long-term unintended side effects, making off-target edits less concerning than DNA-targeting methods.

Therefore, it is necessary to have measurements that can distinguish between muscle and fat mass. Methods of body composition such as Dual Energy X-ray Absorptiometry (DEXA) provide accurate assessments of body composition, but they are resource-intensive and impractical for routine monitoring in clinical or community settings.

Effect of estrogen on myocardial ischemia-reperfusion injury in male and female rats and related mechanism.

Due to the difference of estrogen levels in different phases of estrous cycle, it is necessary to exclude the influence of endogenous estrogen when studying the cardiovascular effects of estrogen and its analogues. In this study, the ischemia/reperfusion (I/R) injury of isolated heart were investigated in female rats during different phases of estrous cycle with male rats as comparison. The results indicated that the estrogen content in blood of rats during metestrus and diestrus (MD) was lower than those during proestrus and estrous (PE).

Biomineralized and metallized small extracellular vesicles encapsulated in hydrogels for mitochondrial-targeted synergistic tumor therapy.

Targeted organelle therapy is a promising therapeutic method for significantly regulating the tumor microenvironment, yet it often lacks effective strategies for leveraging synergistic enhancement effect. Engineered small extracellular vesicles (sEVs) are expected to address this challenge due to their notable advantages in drug delivery, extended circulation time, and intercellular information transmission. Herein, we prepare sEVs with pH and photothermal dual-responsiveness, which are encapsulated with hydrogels for a quadruple-efficient synergistic therapy.
