Pyrolytic Carbon: An Inexpensive, Robust, and Versatile Electrode for Synthetic Organic Electrochemistry.

Synthetic organic electrochemistry is recognized as one of the most sustainable forms of redox chemistry that can enable a wide variety of useful transformations. In this study, readily prepared pyrolytic carbon electrodes are explored in several powerful rAP transformations as well as C-C and C-N bond forming reactions. Pyrolytic carbon provides an alternative to classic amorphous carbon-based materials that are either expensive or ill-suited to large-scale flow reactions.

and are frequent causes of healthcare-associated infections. Antimicrobial-resistant enterococci pose a serious public health threat, particularly vancomycin-resistant enterococci (VRE), for which treatment options are limited. The Centers for Disease Control and Prevention's Division of Healthcare Quality Promotion Sentinel Surveillance system conducted surveillance from 2018 to 2019 to evaluate antimicrobial susceptibility profiles and molecular epidemiology of 205 and 180 clinical isolates collected from nine geographically diverse sites in the United States.

Engineering the substrate specificity and regioselectivity of Burkholderia thailandensis lipoxygenase.

Lipoxygenases (LOXs) catalyze the regioselective dioxygenation of polyunsaturated fatty acids (PUFAs), generating fatty acid hydroperoxides (FAHPs) with diverse industrial applications. Bacterial LOXs have garnered significant attention in recent years due to their broad activity towards PUFAs, yet knowledge about the structural factors influencing their substrate preferences remains limited. Here, we characterized a bacterial LOX from Burkholderia thailandensis (Bt-LOX), and identified key residues affecting its substrate preference and regioselectivity through site-directed mutagenesis.

The bone marrow endothelial progenitor cell response to septic infection.

Early increase in the level of endothelial progenitor cells (EPCs) in the systemic circulation occurs in patients with septic infection/sepsis. The significance and underlying mechanisms of this response remain unclear. This study investigated the bone marrow EPC response in adult mice with septic infection induced by intravenous injection (i.

Reimbursement for a Broader Array of Services in Coordinated Specialty Care for Early Psychosis.

Despite the growing evidence supporting the benefits of coordinated specialty care (CSC) for early psychosis, access to this multimodal, evidence-based program in the United States has been hindered by a lack of funding for core CSC services and activities. The recent approval of team-based reimbursement codes by the Centers for Medicare and Medicaid Services has the potential to fund substantially more CSC services for clients with insurance coverage that accepts the new team-based billing codes. This streamlined and more inclusive billing strategy may reduce administrative burden and support the financial viability of CSC programs.

Versatile ferrous oxidation-xylenol orange assay for high-throughput screening of lipoxygenase activity.

Lipoxygenases (LOXs) catalyze dioxygenation of polyunsaturated fatty acids (PUFAs) into fatty acid hydroperoxides (FAHPs), which can be further transformed into a number of value-added compounds. LOXs have garnered interest as biocatalysts for various industrial applications. Therefore, a high-throughput LOX activity assay is essential to evaluate their performance under different conditions.

Bacterial lipoxygenases: Biochemical characteristics, molecular structure and potential applications.

Lipoxygenases (LOXs) are enzymes that catalyze dioxygenation of polyunsaturated fatty acids into fatty acid hydroperoxides. The formed fatty acid hydroperoxides are of interest as they can readily be transformed to a number of value-added compounds. LOXs are widely distributed in both eukaryotic and prokaryotic organisms, including humans, animals, plants, fungi and bacteria.

Overcoming Limitations in Decarboxylative Arylation via Ag-Ni Electrocatalysis.

A useful protocol for achieving decarboxylative cross-coupling (DCC) of redox-active esters (RAE, isolated or generated in situ) and halo(hetero)arenes is reported. This pragmatically focused study employs a unique Ag-Ni electrocatalytic platform to overcome numerous limitations that have plagued this strategically powerful transformation. In its optimized form, coupling partners can be combined in a surprisingly simple way: open to the air, using technical-grade solvents, an inexpensive ligand and Ni source, and substoichiometric AgNO, proceeding at room temperature with a simple commercial potentiostat.

Back-to-monomer recycling of polycondensation polymers: opportunities for chemicals and enzymes.

The use of plastics in a wide range of applications has grown substantially over recent decades, resulting in enormous growth in production volumes to meet demand. Though a wide range of biomass-derived chemicals and materials are available on the market, the production volumes of such renewable alternatives are currently not sufficient to replace their fossil-based analogues due to various factors, in particular cost-effectiveness. Hence, the majority of plastics are still industrially produced from fossil-based feedstocks.

Molecular species selectivity of lipid transport creates a mitochondrial sink for di-unsaturated phospholipids.

Mitochondria depend on the import of phospholipid precursors for the biosynthesis of phosphatidylethanolamine (PE) and cardiolipin, yet the mechanism of their transport remains elusive. A dynamic lipidomics approach revealed that mitochondria preferentially import di-unsaturated phosphatidylserine (PS) for subsequent conversion to PE by the mitochondrial PS decarboxylase Psd1p. Several protein complexes tethering mitochondria to the endomembrane system have been implicated in lipid transport in yeast, including the endoplasmic reticulum (ER)-mitochondrial encounter structure (ERMES), ER-membrane complex (EMC), and the vacuole and mitochondria patch (vCLAMP).

Association of Combination of Conformation-Specific KIT Inhibitors With Clinical Benefit in Patients With Refractory Gastrointestinal Stromal Tumors: A Phase 1b/2a Nonrandomized Clinical Trial.

Importance: Many cancer subtypes, including KIT-mutant gastrointestinal stromal tumors (GISTs), are driven by activating mutations in tyrosine kinases and may initially respond to kinase inhibitors but frequently relapse owing to outgrowth of heterogeneous subclones with resistance mutations. KIT inhibitors commonly used to treat GIST (eg, imatinib and sunitinib) are inactive-state (type II) inhibitors.

Objective: To assess whether combining a type II KIT inhibitor with a conformation-complementary, active-state (type I) KIT inhibitor is associated with broad mutation coverage and global disease control.

Vanillyl alcohol oxidase.

This review presents a historical outline of the research on vanillyl alcohol oxidase (VAO) from Penicillium simplicissimum, one of the canonical members of the VAO/PCMH flavoprotein family. After describing its discovery and initial biochemical characterization, we discuss the physiological role, substrate scope, and catalytic mechanism of VAO, and review its three-dimensional structure and mechanism of covalent flavinylation. We also explain how protein engineering provided a deeper insight into the role of certain amino acid residues in determining the substrate specificity and enantioselectivity of the enzyme.
