Summary: This study developed a numerical analysis code called COSFIAS to investigate the flow instability of parallel channels in a sodium heated OTSG, validated experimental data, and drew conclusions: decreasing water pressure increases heat transfer power and destabilizes the system; sodium heated condition is more stable compared to uniform heating condition; inlet subcooling in different regions affects the stability of the parallel channels system.

Summary: The newly synthesized bis-photochromic molecules display significant pH response characteristics and potential for use as pH probes in acetonitrile solutions and PMMA membranes. Under ultraviolet light, these compounds exhibit photochromism and 'turn-off' fluorescence properties, possibly due to photoisomerization of the 4,5-diarylimidazole units.

Summary: In this paper, the stability and dynamical relevance of different types of flows between orthogonally stretching parallel plates are explored. It is found that the Stokesian flow is stable, while other flow solutions are unstable. When both plates shrink, a Hopf bifurcation occurs leading to stable time-periodic regimes. Additionally, quasiperiodic flows and chaotic dynamics are observed, but chaotic dynamics is rare.

Summary: Three novel series of alpha-aminoamides derivatives were synthesized based on ralfinamide, and their inhibitory activities against Nav1.7 were evaluated. The most potent compound 19h exhibited significantly higher activity than ralfinamide, and the structure-activity relationship investigation provided a strategy for improving the Nav1.7 inhibition of ralfinamide analogues.

Summary: Chronic pain severely impacts quality of life and requires effective treatments. This study designed, synthesized, and evaluated a series of acyl sulfonamide derivatives targeting NaV1.7 for their antinociceptive activities. Among them, compound 36c was identified as a selective and potent NaV1.7 inhibitor in vitro and showed antinociceptive effects in vivo. The discovery of 36c provides new insights into selective NaV1.7 inhibitors and potential pain therapies.

Summary: The Epithelial Sodium Channel/Degenerin (ENaC/DEG) family is a superfamily of sodium-selective channels with high homology in the pore region, playing important physiological roles in various animal species. The G/SxS selectivity filter and other conserved residues are crucial for ion selectivity, with different residues involved in ion permeability depending on the ion type. This review highlights new perspectives for further exploration of ion selectivity mechanisms.

Summary: The fungicide Tebuconazole affects the sodium current of human cardiac sodium channels by reducing its amplitude in a concentration- and voltage-dependent manner. It alters the inactivation properties and recovery kinetics of the current, and enhances closed-state inactivation and use-dependent block. Furthermore, Tebuconazole reduces the increase in late sodium current induced by another insecticide. These findings suggest a new mechanism of cardiotoxicity attributed to Tebuconazole.

Summary: Molecular surveillance of resistance is crucial in vector borne disease control programmes that use insecticides. The study monitored the frequency of resistance-associated genotypes in India for five years and found a significant increase between 2017 and 2018, followed by relative stability and some reversion in 2021. The study highlights the importance of continued monitoring and improvement of spray quality in order to effectively control vector-borne diseases.

Summary: Novel alpha-aminoamide derivatives containing different benzoheterocyclic moieties were synthesized and evaluated for their potential as voltage-gated sodium ion channel blockers for pain treatment. Compounds 6a, 6e, and 6f displayed stronger in vivo analgesic activity than ralfinamide and also showed potent in vitro anti-Na(v)1.7 and anti-Na(v)1.8 activity, suggesting their potential as new leads for the development of analgesic drugs targeting pain-related Na-v channels.

Summary: This study demonstrates that mice harboring an Scn8a allele with a patient-derived mutation are susceptible to audiogenic seizures and seizure-induced death, providing a new model for studying seizure-induced death. Activation of adrenergic receptors is necessary and sufficient for recovery of breathing and prevention of seizure-induced death in this novel audiogenic seizure-induced death model.

Summary: Glioblastoma (GBM) is an aggressive brain tumor with a poor prognosis. Surgical resection followed by radiotherapy and temozolomide (TMZ) treatment represents the standard strategy for GBM. However, tumor recurrences and TMZ resistance are common, requiring the development of new pharmacological strategies. This study discovered that MV1035, an imidazobenzoxazin-5-thione, can reduce migration and invasiveness of GBM cells and has a synergistic effect when used in combination with TMZ.

Summary: This research aims to evaluate the chargeability of sodium hypochlorite and an air-assisted electrostatic disinfection device. Five different surfaces were examined to assess efficacy, survival time, off-target losses, spray coverage, and disinfectant consumption. The results showed that sodium hypochlorite achieved a significant charge-to-mass ratio of 2.43 mC/kg at specific conditions and effectively eliminated Pseudomonas aeruginosa, Clostridium perfringens, and Bacteriophage MS2 colonies at a concentration of 1000 mg/L.

Summary: Antibiotic resistance is a major threat to public health, with Gram-negative bacteria presenting unique challenges due to their low permeability and efflux pumps. Limited understanding of the chemical rules for overcoming these barriers hinders antibacterial drug discovery. Efforts to address this issue, such as screening compound libraries and using cheminformatic analysis, have led to the design of sulfamidoadenosines with diverse substituents, showing potential utility in accumulation in Escherichia coli.
