Catheter ablation in rate-controlled atrial fibrillation with severely reduced ejection fraction: intervention for irregularity-mediated cardiomyopathy.

Background: Recent evidence suggests atrial fibrillation (AF) causes cardiomyopathy due to remodeling driven by both irregular rate and rhythm. Atrial fibrillation (AF) ablation in patients with reduced ejection fraction (EF) ≤ 35% has been shown to improve EF and mortality. It is unknown whether the benefits of AF ablation among patients with reduced EF are affected by the degree of pre-ablation rate control.

Optical control of sphingolipid biosynthesis using photoswitchable sphingosines.

Sphingolipid metabolism comprises a complex interconnected web of enzymes, metabolites and modes of regulation that influence a wide range of cellular and physiological processes. Deciphering the biological relevance of this network is challenging as numerous intermediates of sphingolipid metabolism are short-lived molecules with often opposing biological activities. Here, we introduce clickable, azobenzene-containing sphingosines, termed caSphs, as light-sensitive substrates for sphingolipid biosynthesis.

Optical Control of TRPM8 Channels with Photoswitchable Menthol.

Transient receptor potential melastatin 8 (TRPM8) channels are well known as sensors for cold temperatures and cooling agents such as menthol and icilin and these channels are tightly regulated by the membrane lipid phosphoinositol-4,5-bisphosphate (PIP). Since TRPM8 channels emerged as promising drug targets for treating pain, itching, obesity, cancer, dry eye disease, and inflammation, we aimed at developing a high-precision TRPM8 channel activator, to achieve spatiotemporal control of TRPM8 activity with light. In this study, we designed, synthesized and characterized the first photoswitchable TRPM8 activator azo-menthol (AzoM).

A new species of Pseudostilobezzia Wirth & Ratanaworabhan (Diptera: Ceratopogonidae) from Vietnam.

A new species of Pseudostilobezzia Wirth & Ratanaworabhan is described, the third in this small genus, from Vietnam and based on two females. A key is provided to distinguish the three species, all restricted to the Oriental Region, in Vietnam or the nearby Hainan province, China. The phylogenetic relationship between this genus and other Ceratopogonidae suggests that it may be a somewhat distinctive lineage within Stilobezzia Kieffer.

Using Hybrid Coating to Fabricate Highly Stable and Expandable Transparent Liquid Marbles.

Liquid marbles (LMs) are microliter-scale droplets coated with hydrophobic solid particles. The particle size and hydrophobicity of the surface coating determine their properties, such as transparency, expandability, and resistance to evaporation and coalescence, one or more of which can be critical to their application as microreactors. This study reports the use of a mixture of two different hydrophobic powders for fabrication of LMs for colorimetric assays: trichloro(1,1,2,2-perfluorooctyl) silane-linked silica gel (modified silica gel (MSG), particle size: 40-75 μm) and hexamethyldisilazane-linked fumed silica (modified fumed silica (MFS), average aggregate length: 200-300 nm).

Ultrasound identification of the cementoenamel junction and clinical correlation through ex vivo analysis.

Accurately identifying periodontal landmarks via acoustic imaging is increasingly important.

Smiles-Rearrangement-Based One-Pot Synthesis of Diarylacetylenes from Benzylic Sulfones and Methyl Benzoates Mediated by LiN(SiMe)/KN(SiMe).

The one-pot synthesis of diphenylacetylene by the reaction of methyl benzoate with 1-(benzylsulfonyl)-3,5-di(trifluoromethyl)benzene was developed. The combination of LiN(SiMe) and KN(SiMe) is key to promoting the reaction. Simply combining methyl benzoate, 1-(benzylsulfonyl)-3,5-di(trifluoromethyl)benzene, LiN(SiMe), and KN(SiMe) can produce a variety of diaryl acetylenes (28 examples, 18-70% yields).

Enantioselective Synthesis of Aminals Via Nickel-Catalyzed Hydroamination of 2-Azadienes with Indoles and N-Heterocycles.

New methods for the enantioselective synthesis of N-alkylated indoles and their derivatives are of great interest because indoles are pivotal structural elements in biologically active molecules and natural products. They are also versatile intermediates in organic synthesis. Among well-established asymmetric hydroamination methods, the asymmetric hydroamination with indole-based substrates is a formidable challenge.

Bank vole genomics links determinate and indeterminate growth of teeth.

Background: Continuously growing teeth are an important innovation in mammalian evolution, yet genetic regulation of continuous growth by stem cells remains incompletely understood. Dental stem cells responsible for tooth crown growth are lost at the onset of tooth root formation. Genetic signaling that initiates this loss is difficult to study with the ever-growing incisor and rooted molars of mice, the most common mammalian dental model species, because signals for root formation overlap with signals that pattern tooth size and shape (i.

Thioamide-based fluorescent sensors for dipeptidyl peptidase 4.

Dipeptidyl peptidase 4 (DPP-4) is a promising biomarker for cancer and metabolic diseases. We demonstrate the design of novel fluorescent DPP-4 probes based on the protease's native substrates using a thioamide as a quencher for measuring kinetics, inhibition with sitagliptin, and DPP-4 activity in saliva samples.

Design, Synthesis, and Structural Evaluation of Acetylated Phenylthioketone Inhibitors of HDAC10.

Histone deacetylase 10 (HDAC10) is unique among the greater HDAC family due to its unusually narrow substrate specificity as a polyamine deacetylase, specifically as an -acetylspermidine hydrolase. Polyamines are essential for cell growth and proliferation; consequently, inhibition of polyamine deacetylation represents a possible strategy for cancer chemotherapy. In this work, we have designed six acetylated phenylthioketone inhibitors of HDAC10 containing positively charged - and -substituted amino groups designed to target interactions with E274, the gatekeeper that recognizes the positively charged ammonium group of the substrate -acetylspermidine.

Controlling the Size of Molecular Copper Clusters Supported by a Multinucleating Macrocycle.

The use of a nonrigid, pyridyldialdimine-derived macrocyclic ligand (PDAI) enabled the synthesis of well-defined mono-, di-, tri-, and tetra-nuclear Cu(I) complexes in good yields through rational synthetic means. Starting from mono- and diargentous PDAI complexes, transmetalation to Cu(I) proceeded smoothly with formation of AgX (X = Cl, I) salts to generate mono-, di-, and trinuclear copper complexes. Monodentate supporting ligands (MeCN, xylNC, PMe, PPh) were found to either transmetallate with or bind various di- and trinuclear clusters.

Cell-Specific Optical Control of AMPA Glutamate Receptors with a Photoswitchable Tethered Antagonist.

AMPA receptors (AMPARs) are the main drivers of excitatory glutamatergic transmission in the brain, central to synaptic plasticity, and are key drug targets. However, AMPARs are expressed in virtually every neuron in the central nervous system and are activated with complex temporal dynamics, making it difficult to determine their functional roles with sufficient precision. Here we describe a cell specific, light-controllable competitive antagonist for the AMPA receptor called MP-GluA that combines the temporal precision of a photo-switchable ligand with the spatial and cellular specificity of a genetically-encoded membrane-anchor protein.
