A High-Performance Polyimide Composite Membrane with Flexible Polyphosphazene Derivatives for Vanadium Redox Flow Battery.

A sulfonated polyimide, S-F-abSPI, with alkyl sulfonic acid side chains, and a polyphosphonitrile derivative, poly[4-methoxyphenoxy (4-fluorophenoxy) phosphazene] (PFMPP), were designed and synthesized. Composite modification of the S-F-abSPI membrane was carried out using PFMPP, resulting in the preparation of composite membranes with different composite ratios, which were then subjected to performance testing and characterization. Experimental results revealed a significant enhancement in the proton conductivity of the S-F-abSPI membrane, reaching 0.

What Limits the Stability Performance of Polymeric Carbon Nitride Photoanode for Photoelectrochemical Water Splitting?

Although many researches have been reported about the high performance of polymeric carbon nitride (PCN) photoanode, but it is still limited by poor stability. In this work, PCN nanosheets photoanode is used as a platform to investigate the sources of this issue. Through a combination of photoelectrochemical, X-ray Photoelectron Spectroscopy (XPS), and Potentiostatic Electrochemical Impedance Spectroscopy (PIES) measurements, it is shown that amounts of C═O bonds will form on the surface of PCN photoanodes, which limited the separation of the photogenerated carriers.

Methods: This retrospective study was conducted with data from patients who underwent PELD for LSS between January 2021 and December 2023.

IRF3 Promotes Asthma Pathogenesis by Regulating Type 2 Innate Lymphoid Cells.

Background: Allergic asthma is characterized by airway hyperresponsiveness triggered by inhaled allergens. Type 2 innate lymphoid cells (ILC2s) have been demonstrated to play a crucial role in promoting airway inflammation through the secretion of type 2 effector cytokines. However, the mechanisms underlying the functions of lung ILC2s remain unclear.

Clinical characteristics of idiopathic inflammatory myopathies related to anti-SRP: a single center experience.

Idiopathic inflammatory myopathy (IIM) with autoantibodies recognizing the signal recognition particle (SRP) is characterized by prominent proximal weakness, infrequent extramuscular involvement, dramatically elevated creatine kinase levels, and myofiber necrosis with few inflammatory cell infiltrates in muscle tissue.

A Novel Sulfonated Polyimide Composite Membrane Containing a Sulfonated Porous Material for All-Vanadium Redox Flow Batteries.

To improve the battery efficiency and cycling stability of sulfonated polyimide (SPI), a polyphosphazene with built-in -SOH moieties (PP-SOH), which is a porous covalent organic framework (COF) material, is facilely synthesized by the polymeric combination of hexachlorocyclotriphosphazene (HCCP) and -diaminobenzenesulfonic acid. Due to its tunable pore size and flexible molecular design, the COF material can address the trade-off between the conductivity and the ion permeability of ion exchange membranes well, thereby improving the ion selectivity of membranes. The experimental results show that the SPI/PP-SOH composite membrane has an excellent conductivity (up to 114.

Synthetic lethality of combined ULK1 defection and p53 restoration induce pyroptosis by directly upregulating GSDME transcription and cleavage activation through ROS/NLRP3 signaling.

Background: High expression of ubiquitin ligase MDM2 is a primary cause of p53 inactivation in many tumors, making it a promising therapeutic target. However, MDM2 inhibitors have failed in clinical trials due to p53-induced feedback that enhances MDM2 expression. This underscores the urgent need to find an effective adaptive genotype or combination of targets.

Preoperative application of CT and MRI registration in lumbar disc herniation endoscopic surgery could improve the postoperative rehabilitation of patients.

Background: Percutaneous Endoscopic Lumbar Discectomy (PELD) has emerged as routine treatment for lumbar disc herniation (LDH) due to its minimal invasiveness and quick recovery. However, PELD demands high precision from the surgeon, as the risk of intraoperative complications is substantial, including potential damage to the nerve root and dura, and a higher likelihood of recurrence post-surgery. Thus, preoperative planning utilizing CT and MRI imaging is essential.

Exploring the oncogenic potential of circSOD2 in clear cell renal cell carcinoma: a novel positive feedback loop.

Background: Existing studies have found that circular RNAs (circRNAs) act as sponges for micro RNAs (miRNAs) to control downstream genes. However, the specific functionalities and mechanisms of circRNAs in human clear cell renal cell carcinoma (ccRCC) have yet to be thoroughly investigated.

Methods: Patient cohorts from online databases were used to screen candidate circRNAs, while another cohort from our hospital was obtained for validation.

Enhanced Photocatalytic Hydrogen Evolution of InS by Decorating InO with Rich Oxygen Vacancies.

The hydrogen (H) evolution rates of photocatalysts suffer from weak oxidation and reduction ability and low photogenerated charge carrier separation efficiency. Herein, by combining band-gap structure optimization and vacancy modulation through a one-step hydrothermal method, InO containing oxygen vacancy (O/InO) is simply introduced into InS to promote photocatalytic hydrogen evolution. Specifically, the change in the sulfur source ratio can induce the coexistence of O/InO and InS in a high-temperature hydrothermal process.

Objective: To examine the potential of galangin in a mouse model of ovalbumin (OVA)-induced allergic rhinitis (AR), as chronic AR, induced by immunoglobulin-E (IgE), leads to histamine release and nasal inflammation, and although galangin exhibits antiasthmatic and anti-inflammatory potential, its effect on AR is yet to be investigated.

Animals: 126 BALB/c mice.

Methods: AR induction involved sensitizing female mice with OVA (5%, 500 µL, IP) for 14 days.

PI3K/AKT mediated De novo fatty acid synthesis regulates RIG-1/MDA-5-dependent type I IFN responses in BVDV-infected CD8T cells.
