Pharmacokinetics and pharmacodynamics of ciprofol after continuous infusion in elderly patients.

Background: Ciprofol, a novel intravenous anesthetic, which has primarily been used for the induction and maintenance of general anesthesia in adults, is characterized by rapid onset, short duration of action, and quick and smooth recovery. However, the pharmacokinetic characteristics of continuous infusions and the correlation between the plasma concentration and the bispectral index (BIS) in elderly patients are still unknown.

Method: In this randomized, controlled study, thirty elderly patients (62-78 years old) undergoing elective gastrointestinal tumor resection were treated with propofol (N = 15) or ciprofol (N = 15) as sedatives during anesthesia.

CeO Modification Promotes the Oxidation Kinetics for Adipic Acid Electrosynthesis from KA Oil Oxidation at 200 mA cm.

Electrocatalytic oxidation of cyclohexanol/cyclohexanone in water provides a promising strategy for obtaining adipic acid (AA), which is an essential feedstock in the polymer industry. However, this process is impeded by slow kinetics and limited Faradaic efficiency (FE) due to a poor understanding of the reaction mechanism. Herein, NiCoO/CeO is developed to enable the electrooxidation of cyclohexanol to AA with a 0.

Enhancing D-lactic acid production from non-detoxified corn stover hydrolysate via innovative F127-IEA hydrogel-mediated immobilization of T15.

Background: The production of D-lactic acid (D-LA) from non-detoxified corn stover hydrolysate is hindered by substrate-mediated inhibition and low cell utilization times. In this study, we developed a novel temperature-sensitive hydrogel, F127-IEA, for efficient D-LA production using a cell-recycle batch fermentation process.

Results: F127-IEA exhibited a porous structure with an average pore size of approximately 1 μm, facilitating the formation of stable clusters within the gel matrix.

Values of H-Type Hypertension in Patients with Large Vessel Occlusion.

Background And Purpose: Many patients who gained successful recanalization by endovascular treatment (EVT) with acute large vessel occlusion (LVO) did not have the favorable outcome. The study aimed to assess the association between H-type hypertension and clinical prognosis in patients with LVO after receiving EVT.

Methods: Our study enrolled patients from the Endovascular Treatment With versus Without Tirofiban for Stroke Patients with Large Vessel Occlusion (RESCUE BT) Trial.

Association of Conscious Sedation With Dexmedetomidine and Outcome in Stroke Patients Undergoing Thrombectomy in the DEVT and RESCUE-BT Trials.

Background And Objectives: Although dexmedetomidine (DEX) is widely administered during endovascular treatment (EVT) to enhance procedural adherence of patients with acute ischemic stroke (AIS) with large vessel occlusion, there is limited research on the association of DEX and outcomes among these patients. Hence, this study aimed to explore the safety and outcomes of DEX during conscious sedation (CS) in a real-world setting among patients undergoing EVT.

Methods: This study was an individual patient-level pooled analysis of 2 multicenter randomized clinical trials RESCUE-BT and DEVT.

Amorphous Cu/Fe nanoparticles with tandem intracellular and extracellular electron capacity for enhancing denitrification performance and recovery of co-contaminant suppressed denitrification.

In this study, a functionally stable insoluble Cu/Fe nanoparticles (Cu/Fe NPs) were synthesized and applied denitrification with different contaminants. The results showed that 50 mg/L Cu/Fe NPs increased NO-N reduction rate up to 14.3 mg/(L·h) about 3 folds compared with the control system (4.

Comprehensive screening of industrially relevant components at genome scale using a high-quality gene overexpression collection of Corynebacterium glutamicum.

Development of efficient microbial strains for biomanufacturing requires deep understanding of the biology and functional components responsible for the synthesis, transport, and tolerance of the target compounds. A high-quality controllable gene overexpression strain collection was constructed for the industrial workhorse Corynebacterium glutamicum covering 99.7% of its genes.

Pharmacokinetics and safety of colistin sulfate after single and multiple intravenous doses in healthy Chinese subjects.

Objective: Increasing antimicrobial resistance has led to the revival of the polymyxins as a last-resort therapeutic option for multidrug-resistant Gram-negative bacterial infections. A parenteral formulation of colistin sulfate is available solely in China. While the onset of action of IV colistin may occur faster than with its prodrug CMS, its pharmacokinetic (PK) profile remains unclear.
