FadR-based biosensor assisted screening for genes enhancing fatty acyl-CoA pools in Saccharomyces cerevisiae.

Fatty acid-derived compounds have a range of industrial applications, from chemical building blocks to biofuels. Due to the highly dynamic nature of fatty acid metabolism, it is difficult to identify genes modulating fatty acyl-CoA levels using a rational approach. Metabolite biosensors can be used to screen genes from large-scale libraries in vivo in a high throughput manner. Here, a fatty acyl-CoA sensor based on the transcription factor FadR from Escherichia coli was established in Saccharomyces cerevisi...


Generation of Microsecond Charge-Separated Excited States in Rhenium(I) Diimine Complexes: Driving Force Is the Dominant Factor in Controlling Lifetime.

A transition-metal-based donor-(linker)-acceptor system can produce long-lived charge transfer excited states using visible excitation wavelengths. The ground- and excited-state photophysical properties of a series of [ReCl(CO)(dppz-(linker)-TPA)] complexes, with varying donor and acceptor energies, have been systematically studied using spectroscopic techniques (both vibrational and electronic) supported by computational chemistry. The long-lived excited state is ILCT in nature for all complexes studied, c...

HS-SPME-GC-MS Quantification of Volatile Profile of more than 1200 Virgin Olive Oils for Supporting Panel Test in their Classification: Comparison of Different Chemometric Approaches.

A reliable and robust tool for supporting panel test in virgin olive oil classification is still required. We propose four chemometric approaches based on t-test, PCA and LDA, applied for combining sensorial data and chemical measurements. The former were from the panel test and the latter from HS-SPME-GC-MS quantitation of 73 volatile organic compounds of 1223 typical commercial virgin olive oils, the most of them recognized difficult to classify with accuracy by panel test. The approaches were developed a...


Coumarin-Based Small-Molecule Fluorescent Chemosensors.

Coumarins are a very large family of compounds containing the unique 2-chromen-2-one motif, as it is known according to IUPAC nomenclature. Coumarin derivatives are widely found in nature, especially in plants and are constituents of several essential oils. Up to now, thousands of coumarin derivatives have been isolated from nature or produced by chemists. More recently, the coumarin platform has been widely adopted in the design of small-molecule fluorescent chemosensors because of its excellent biocompati...

Glyconanoparticles for Targeted Tumor Therapy of Platinum Anticancer Drug.

An important requirement to decrease the side effects of chemotherapy drugs is to develop nanocarriers with precise biological functions. In this work, a set of glyconanoparticles was prepared via self-assembly of amphiphilic glycoblock copolymers for the targeted delivery of a hydrophobic chemotherapy drug. Well-defined glycoblock copolymers that consist of 1,1-di-tert-butyl 3-(2-(metyloyloxy)ethyl)-butane-1,1,3-tricarboxylate (MAETC) together with three different protected-sugar moieties (β-D-glucopyrano...

Dinitrogen Fixation and Reduction by Ta3N3H0,1- Cluster Anions at Room Temperature: Hydrogen-Assisted Enhancement of Reactivity.

Dinitrogen activation and reduction is one of the most challenging and important subjects in chemistry. Herein, we report the N2 binding and reduction at the well-defined Ta3N3H- and Ta3N3- gas-phase clusters by using mass spec-trometry (MS), anion photoelectron spectroscopy (PES), and quantum-chemical calculations. The PES and calculation results show clear evidence that N2 can be adsorbed and completely activated by Ta3N3H- and Ta3N3- clusters, yielding to the products Ta3N5H- and Ta3N5-, but the reactivi...

Calculation of molecular vibrational spectra on a quantum annealer.

Until recently molecular energy calculations using quantum computing hardware have been limited to gate-based quantum computers. In this paper, a new methodology is presented to calculate the vibrational spectrum of a molecule on a quantum annealer. The key idea of the method is a mapping of the ground state variational problem onto an Ising or quadratic unconstrained binary optimization (QUBO) problem by expressing the expansion coefficients using spins or qubits. The algorithm is general and represents a ...

Identification of -Methyl Nicotinamide and -Methyl Pyridazine-3-Carboxamide Pseudokinase Domain Ligands as Highly Selective Allosteric Inhibitors of Tyrosine Kinase 2 (TYK2).

As a member of the Janus (JAK) family of nonreceptor tyrosine kinases, TYK2 plays an important role in mediating the signaling of pro-inflammatory cytokines including IL-12, IL-23, and type 1 interferons. The nicotinamide , identified by a SPA-based high-throughput screen targeting the TYK2 pseudokinase domain, potently inhibits IL-23 and IFNα signaling in cellular assays. The described work details the optimization of this poorly selective hit () to potent and selective molecules such as and . The discov...

Lewis Strength Determines Specific-Ion Effects in Aqueous and Nonaqueous Solvents.

An analysis of specific-ion effects in aqueous and nonaqueous solvents using energy decomposition analysis is presented. Specific-ion effects induce or influence physicochemical phenomena in a way that is determined by the identity of the ions present, and not merely by their charge or concentration. Such effects have been known since the seminal work of Hofmeister and are often categorized according to the well-known Hofmeister series. Examples of specific-ion effects are ubiquitous throughout chemistry an...

Blind search for complex chemical pathways using Harmonic Linear Discriminant Analysis.

Disentangling the mechanistic details of a chemical reaction pathway is a hard problem that often requires a considerable amount of chemical intuition and a component of luck. Experiments struggle in observing short-life metastable intermediates, while computer simulations often rely upon a good initial guess. In this work, we propose a method that, from the simulations of a reactant and a product state, searches for reaction mechanisms connecting the two by exploring the configuration space through metadyn...

Geminiarene: Molecular Scale Dual Selectivity for Chlorobenzene and Chlorocyclohexane Fractionation.

In this work, a new version of macrocyclic arenes, namely geminiarene, has been designed and synthesized for guest complexation and chlorobenzene/chlorocyclohexane mixture separation with excellent dual selectivity. Due to its unique dual/gemini conformational feature, not only chlorocyclohexane can be separated from chlorobenzene with exceeding 97% purity, but also chlorobenzene can be separated from chlorocyclohexane with purity over 88%, and the dual selective fractionation process could be achieved in o...

Time-Resolved Photoelectron Imaging of Acetone with 9.3 eV Photoexcitation.

Ultrafast electronic relaxation following 9.3-eV photoexcitation of gaseous acetone was investigated with time-resolved photoelectron imaging. An intense photoionization signal due to a transition from the 4A(ππ*) state to the D(π) cationic state diminishes within 50 fs, owing to vibrational wave packet motion leaving our observation energy window. Additional photoionization signals were assigned to transitions from Rydberg states with principal quantum numbers of 3 - 8 to the D(n) cationic state, create...

A Grid-Based Ehrenfest Model to Study Electron-Nuclear Processes.

The two-dimensional electron-nuclear Schrödinger equation using soft-core Coulomb potentials has been a cornerstone for modeling and predicting the behavior of one-active-electron diatomic molecules, particularly for processes where both bound and continuum states are important. The model, however, is computationally expensive to extend to more electron or nuclear coordinates. Here we propose to use the Ehrenfest approach to treat the nuclear motion, while the electronic motion is still solved by quantum p...

Clinically Applicable Deep Learning Algorithm Using Quantitative Proteomic Data.

Deep learning (DL), a type of machine learning approach, is a powerful tool for analyzing large sets of data that are derived from biomedical sciences. However, it remains unknown whether DL is suitable for identifying contributing factors, such as biomarkers, in quantitative proteomics data. In this study, we describe an optimized DL-based analytical approach using a data set that was generated by selected reaction monitoring-mass spectrometry (SRM-MS), comprising SRM-MS data from 1008 samples for the diag...

Persuasive Evidence for Electron-Nuclear Coupling in Diluted Magnetic Colloidal Nanoplatelets Using Optically Detected Magnetic Resonance Spectroscopy.

The incorporation of magnetic impurities into semiconductor nanocrystals with size confinement, promotes enhanced spin exchange interaction between photo-generated carriers and the guest spins. This interaction stimulates new magneto-optical properties with significant merits for emerging spin-based technologies. Here we observe and elaborate on carrier-guest interactions in magnetically doped colloidal nanoplatelets with the chemical formula CdSe/Cd1-xMnxS, explored by optically detected magnetic resonance...

Vascular Alpha-1 Adrenergic Sensitivity is Enhanced in Chronic Kidney Disease.

Chronic Kidney Disease (CKD) is often complicated by difficult-to-control hypertension, in part due to chronic overactivation of the sympathetic nervous system (SNS). CKD patients also exhibit a greater increase in arterial blood pressure for a given increase in sympathetic nerve activation, suggesting an augmented vasoconstrictive response to SNS activation (i.e. neurovascular transduction). One potential mechanism of increased sympathetic neurovascular transduction is heightened sensitivity of the vascula...

Heart failure developed after myocardial infarction does not affect gut microbiota composition in the rat.

There is a body of evidence that supports that gut dysbiosis plays a role in the pathogenesis of cardiovascular diseases. Decreased cardiac function can reduce intestinal perfusion, resulting in morphological alterations witch may contribute to changes in the gut microbiota composition in heart failure (HF) patients. In this regard, a germane question is whether changes in gut microbiota composition are a cause or consequence of the cardiovascular disturbance. We tested the hypothesis that the development o...

Methods for the Watch the Spot Trial: A Pragmatic Trial of More vs. Less Intensive Strategies for Active Surveillance of Small Pulmonary Nodules.

Small pulmonary nodules are most often managed by surveillance imaging with chest computed tomography (CT), but the optimal frequency and duration of surveillance are unknown. The Watch the Spot Trial is a multi-center, pragmatic, comparative effectiveness trial with cluster randomization by hospital or health system that compares more vs. less intensive strategies for active surveillance of small pulmonary nodules. The study plans to enroll approximately 35,200 patients with a small pulmonary nodule that i...

High-Content Screening Identifies New Inhibitors of Connexin 43 Gap Junctions.

Gap junctions (GJs) are dynamic structures composed of hexamers of connexins (Cxs), a class of transmembrane proteins enabling channel-mediated direct intercellular communication through cell-cell diffusion of ions and small metabolites. In defined conditions, Cxs also work as hemichannels allowing exchanges between the cytoplasm and the extracellular medium. The most common GJ channel is formed by connexin 43 (Cx43) and plays an important role in physiological and pathological processes in excitable tissue...
