Materials‐Guided Gene‐Ionizable Lipid Nanoparticles to Reverse Iron‐Associated Immune Resistance in Renal Cancer

Advanced Science, EarlyView.
ABSTRACT Iron overload is a common metabolic disturbance in cancer and contributes to poor outcomes in renal cell carcinoma (RCC), yet its effects on the tumour immune microenvironment remain unclear. Here we identify a previously unrecognized immunosuppressive axis in which iron overload downregulates the palmitoyltransferase ZDHHC12 in CD8+ T cells ...

Neuromuscular blocking agents. Replacement of quaternary ammonium groups in bis-onium compounds by amidinium, guanidinium, thiouronium, sulphonium and sulphoxonium groups

, 1970
The quaternary ammonium groups of suxamethonium have been replaced by amidinium, guanidinium and thiouronium groups. The guanidine compound exhibited competitive neuromuscular activity of a low order of potency; the other compounds were ineffective ...

Kinsenoside Targets IDH1 to Restore Microglial Immune‐Metabolic Homeostasis for Alzheimer's Disease Therapy

Advanced Science, EarlyView.
Dysregulated TCA cycle contributes to Alzheimer's disease (AD) pathogenesis. Here, we show that microglial isocitrate dehydrogenase 1 (IDH1) is a critical driver. Elevated IDH1 disrupts citrate metabolism and mitochondrial function, exacerbating AD pathology.

Ion-pair hollow-fiber liquid-phase microextraction of the quaternary ammonium surfactant dicocodimethylammonium chloride

, 2009
A two-phase hollow-fiber (HF) liquid-phase microextraction (LPME) method was developed for determination of a quaternary ammonium compound surfactant, dicocodimethylammonium chloride, in aqueous samples. The porous HF was fixed on a metal rod support and

Advanced Dental Composite Technology via Bisilanized Dual‐Action Nanofillers for Biofilm Control

Advanced Science, EarlyView.
A multimodal research strategy has led to the development of an innovative resin‐based composite (RBC) with dual antibacterial action. The S_CM‐RBC formula showed strong antibiofilm activity, excellent mechanical strength, and biosafety. It effectively controlled oral bacteria in prevention of caries recurrence, and maintained pulp health in a rat ...

Mechanism of Osmotic Activation of the Quaternary Ammonium Compound Transporter (QacT) of Lactobacillus plantarum [PDF]

, 1998
The accumulation of quaternary ammonium compounds in Lactobacillus plantarum is mediated via a single transport system with a high affinity for glycine betaine (apparent Km of 18 μM) and carnitine and a low affinity for proline (apparent Km of 950 μM ...

Programmable Hydration Pathways Enable Reconfigurable Ionic Thermoelectrics for Energy Harvesting and Thermal‐Tactile Interaction

Advanced Science, EarlyView.
Programmable hydration pathways enable reconfigurable ionic thermoelectrics in polyquaternium hydrogels. By coupling microscopic solvation, mesoscale water channels, and macroscopic boundary control, hydration‐gated protonics decouples thermopower, response speed, and stability.
