In Situ Composites of Phthalocyanine-Based Covalent Organic Frameworks with Carbon Cloth as a Flexible Binder-Free Anode Material for High-Performance Lithium/Sodium-Ion Batteries.

In situ Schiff base reaction is utilized to grow phthalocyanine covalent organic frameworks (TFPB-NiPc) on carbon cloth (CC) to obtain the composite material TFPB-NiPc@CC, which is used as the anode for the binder and conductive agent free Li/Na-ion batteries with enhanced active materials loading. What is more, CC acts as an excellent conductive backbone while reducing the stacking effect of phthalocyanine frameworks (Pc-COFs), which enables TFPB-NiPc to realize the self-exfoliation effect during the in situ synthesis process. This strategy shortens the migration path of Li, efficiently resulting in improving the migration rate of Li in the electrode.

Monitoring of inflammatory preterm responses via myometrial cell based multimodal electrophysiological and optical biosensing platform.

Preterm birth (PTB) remains a leading cause of neonatal morbidity and mortality, with inflammation-induced PTB posing a significant challenge due to its complex pathophysiology. To address this, we developed an in vitro platform utilizing hTERT-immortalized human myometrial (hTERT-HM) cells integrated with a multielectrode array (MEA) biosensing system and optical calcium imaging. Compared to primary uterine myometrial cells, hTERT-HM cells exhibit superior reproducibility, high scalability, and convenient manipulation, facilitating the consistent and large-scale investigations.

Effects of Microbes on Insect Host Physiology and Behavior Mediated by the Host Immune System.

Innate immunity is critical for insects to adjust to complicated environments. Studying the insect immune system can aid in identifying novel insecticide targets and provide insights for developing novel pest control strategies. Insects recognize environmental pathogens through pattern recognition receptors, thus activating the innate immune system to eliminate pathogens.

Proteomic analysis of the nonstructural protein 2-host protein interactome reveals a novel regulatory role of SH3 domain-containing kinase-binding protein 1 in porcine reproductive and respiratory syndrome virus replication and apoptosis.

Virus-host protein interaction is critical for successful completion of viral replication cycles. As the largest nonstructural protein (NSP) of porcine reproductive and respiratory syndrome virus (PRRSV), NSP2 plays multiple and critical roles in viral replication, antiviral immunity, cellular tropism and virulence. An interactome of this protein with host proteins would be instrumental in full understanding of these multifunctional roles.
