SLC27A3 downregulation restores Th17/Treg balance and alleviates COPD via JAK2/STAT3 pathway inhibition.

The main goal of this investigation is to find out how solute carrier family 27 member 3 (SLC27A3) is expressed in the lung tissue of mice with chronic obstructive pulmonary disease (COPD), and how it relates to lung function. A model of COPD was established by exposing organisms to cigarette smoke, followed by investigating the role of SLC27A3 in COPD through experiments conducted both in living organisms and in laboratory settings. Knockout mice lacking SLC27A3 were produced through siRNA transfection to investigate lung function and inflammatory response, using methods such as hematoxylin-eosin staining and enzyme-linked immunosorbent assay.

Deep Red-Light-Mediated Nitric Oxide and Photodynamic Synergistic Antibacterial Therapy for the Treatment of Drug-Resistant Bacterial Infections.

Infections caused by persistent, drug-resistant bacteria pose significant challenges in inflammation treatment, often leading to severe morbidity and mortality. Herein, the photosensitizer rhodamine derivatives are selected as the light-trapping dye and the electron-rich substituent N-nitrosoaminophen as the nitric oxide (NO)-releasing component to develop a multifunctional (deep) red-light activatable NO photocage/photodynamic prodrug for efficient treatment of wounds and diabetic foot infections. The prodrug, RhB-NO-2 integrates antimicrobial photodynamic therapy (aPDT), NO sterilization, and NO-mediated anti-inflammatory properties within a small organic molecule and is capable of releasing NO and generating Reactive oxygen species (ROS) when exposed to (deep) red laser (660 nm).

Exercise training alleviates neuronal apoptosis and re-establishes mitochondrial quality control after cerebral ischemia by increasing SIRT3 expression.

Existing evidence indicates that exercise training can enhance neural function by regulating mitochondrial quality control (MQC), which can be impaired by cerebral ischemia, and that sirtuin-3 (SIRT3), a protein localized in mitochondria, is crucial in maintaining mitochondrial functions. However, the relationship among exercise training, SIRT3, and MQC after cerebral ischemia remains obscure. This study attempted to elucidate the relationship among exercise training, SIRT3 and MQC after cerebral ischemia in rats.

Photoresponsive nitric oxide photocage/photodynamic integrated prodrug for advanced management of drug-resistant bacteria-infected wound therapy.

Single treatment methods for wound infections caused by drug-resistant bacteria often fail to simultaneously achieve high antimicrobial efficacy and wound healing efficiency. Therefore, it is crucial to develop a small molecule prodrug that can achieve both goals, in this context, we have engineered a green-light-activated nitric oxide photocage/photodynamic therapeutic prodrug, designed to release NO, which not only potentiates antimicrobial efficacy but also facilitates collagen accumulation at the wound interface, thereby expediting the wound healing process. Additionally, it mitigates tissue inflammation by suppressing the NF-κB signaling pathway.

Ocular Gene Therapy: An Overview of Viral Vectors, Immune Responses, and Future Directions.

Ocular gene therapy has rapidly advanced from proof-of-concept studies to clinical trials by exploiting the unique advantages of the eye, including its easy accessibility, relative immune privilege, and the ability to use the contralateral eye as a control. An important step forward was achieved with the Food and Drug Administration (FDA) approval of voretigene neparvovec (Luxturna) for the treatment of biallelic RPE65-mutation-associated retinal dystrophies in 2017. Gene therapy is a promising field aimed at treating various inherited and acquired eye diseases.

Superior Capacitive Energy Storage at High Temperature of All-Organic Aromatic Polymer via Enhancing Conjugate Angle between Benzene Rings.

High-temperature polymer capacitors with superior energy storage density are considerable and desirable components in advanced power pulse, electrical, and energy conversion systems. However, due to the π-π conjugated benzene ring structure, carriers migrate through polyimide (PI) chains, reducing discharge energy density () and charge-discharge efficiency (η) at high temperature. Here, the ether (-O-) and isopropylidene (-C(CH)-) groups are purposefully introduced into the position between the benzene rings to increase the conjugate angle in PI chains, and spatial folded chains are designed to impede charge transport at high temperature.
