Heart failure (HF) is the most common discharge diagnosis across the United States, and these patients are particularly vulnerable to readmissions, increasing attention to potential ways to address the problem. The study cohort was derived from the Healthcare Cost and Utilization Project's National Readmission Data 2013, sponsored by the Agency for Healthcare Research and Quality. HF was identified using appropriate International Classification of Diseases, Ninth Revision, Clinical Modification codes. Readmission was defined as a subsequent hospital admission within 30 days after discharge day of index admission...

REVIEW
Chiara Valtolina, Robert P Favier
Feline hepatic lipidosis (FHL) is a common and potentially fatal liver disorder. Although the pathophysiologic mechanisms of FHL remain elusive, there is an imbalance between the influx of fatty acids from peripheral fat stores into the liver, de novo liposynthesis, and the rate of hepatic oxidation and dispersal of hepatic TAG via excretion of very-low density lipoproteins. The diagnosis of FHL is based on anamnestic, clinical, and clinicopathologic findings, associated with diagnostic imaging of the liver, and cytology, or histological examination of liver biopsies...

In this study, a liquid cathode glow discharge-atomic emission spectrometry (LCGD-AES) was constructed for simultaneously determination of Cu and Pb in digested ores samples, in which the glow discharge was produced between the needle-like Pt anode and electrolyte overflowing from quartz capillary. The stability of LCGD and the effects of discharge voltage, capillary diameter and flow rate on emission intensity were systematically investigated. The limits of detections (LODs) of Cu and Pb were compared with those measured by closed-type electrolyte cathode discharge-atomic emission spectrometry (ELCAD-AES)...

A method to trap magnetic nanoparticles inside the electrophoretic capillary has been developed without disabling and disturbing the coolant liquid recirculation. The complete optimization from setting up of the external magnetic field to injecting the magnetic nanoparticles in order to facilitate efficient trapping is described. In addition to this, the setup has been tested with 150mM sodium phosphate buffer as the background electrolyte at different pH values (2, 4, 6 and 8). All these pH values have been investigated at 25°C and 37°C to mimic room temperature and physiological temperature, respectively...

This work reports a facile electrolyzing method to synthesize boron-doped graphene quantum dots (BGQDs) and uses the BGQDs as a fluorescent probe to determine Fe(3+) ion levels in water samples. The BGQDs were produced by oxidizing graphite in an aqueous borax solution at pH 7; then, the borate solution was filtered with BGQDs, and the borate was dialyzed from the filtrate, leaving a solution of BGQDs in water. The amount of the B in the BGQDs can be adjusted by changing the concentration of borax used for the electrolyte...

Nanopores, and nanoporous materials in general, are interesting for applications in chemical and biomolecular transport as pore sizes are on the same scale as the dimension of many (bio)chemical species. Many studies have focused on either single pores or small arrays of cylindrical pores, which are convenient in terms of their amenability towards computational modeling of transport phenomenon. However, the limited overall porosity may inhibit transport flux as well as the eventual implementation of these materials as active separation elements...

Metal-air batteries are intensively studied because of their high theoretical energy storage capability. However, the fundamental science at work dealing with electrodes, electrolytes and reaction products still need to be better understood. In this report, the ionic liquid N-butyl-N-methylpyrrolidinium bis(trifluoromethanesulfonyl) imide (PYR14TFSI) is chosen to study the influence of a wide range of metal cations (Mn+) on the electrochemical behavior of oxygen.. We demonstrate the relevance of the Lewis hard-soft acid-base (HSAB) theory to predict satisfactorily the reduction potential of the oxygen reduction in electrolytes containing metal cations...

Well-controlled nanostructures and a high fraction of Sn/Li2 O interface are critical to enhance the coulombic efficiency and cyclic performance of SnO2 -based electrodes for lithium-ion batteries (LIBs). Polydopamine (PDA)-coated SnO2 nanocrystals, composed of hundreds of PDA-coated "corn-like" SnO2 nanoparticles (diameter ca. 5 nm) decorated along a "cob", addressed the irreversibility issue of SnO2 -based electrodes. The PDA-coated SnO2 were crafted by capitalizing on rationally designed bottlebrush-like hydroxypropyl cellulose-graft-poly (acrylic acid) (HPC-g-PAA) as a template and was coated with PDA to construct a passivating solid-electrolyte interphase (SEI) layer...

Systems for time sequential capture of microliter volumes of sweat released from targeted regions of the skin offer the potential to enable analysis of temporal variations in electrolyte balance and biomarker concentration throughout a period of interest. Current methods that rely on absorbent pads taped to the skin do not offer the ease of use in sweat capture needed for quantitative tracking; emerging classes of electronic wearable sweat analysis systems do not directly manage sweat-induced fluid flows for sample isolation...

BACKGROUND: Fluid resuscitation is a crucial therapy for sepsis, and the use of balanced fluids and/or isotonic albumin may improve patient survival. We have previously demonstrated that resuscitation with normal saline results in increased hepatic leukocyte recruitment in a murine model of sepsis. Given that clinical formulations of albumin are in saline, our objectives were to develop a novel balanced electrolyte solution specifically for sepsis and to determine if supplementing this solution with albumin would improve the inflammatory response in sepsis...

A delicate interplay of anisotropic hydrophobic/hydrophilic, π-π stacking, ionic and hydrogen bond interactions determine the strength of hydrogelators and are considered key factors in efforts to design potent small molecule hydrogelators. Here we show that solvent deuteration and electrolytic strength affect the strength of hydrogels formed from amino acid modified C3-symmetric cyclohexane trisamides profoundly. Gels formed by self-assembly through heating/cooling of solutions or by pH switching show up to a 30 °C increase in their melting temperatures in D2O compared to H2O...

Metal sulfides are commonly used in energy storage and electrocatalysts due to their redox centers and active sites. Most literature reports show that their performance decreases significantly caused by oxidation in alkaline electrolyte during electrochemical testing. Herein, S and N co-doped graphene-based nickel cobalt sulfide aerogels are synthesized for use as rechargeable alkaline battery electrodes and oxygen reduction reaction (ORR) catalysts. Notably, this system shows improved cyclability due to the stabilization effect of the S and N co-doped graphene aerogel (SNGA)...

The formation of lithium dendrites induces the notorious safety issue and poor cycling life of energy storage devices, such as lithium-sulfur and lithium-air batteries. We propose a surface energy model to describe the complex interface between the lithium anode and electrolyte. A universal strategy of hindering formation of lithium dendrites via tuning surface energy of the relevant thin film growth is suggested. The merit of the novel motif lies not only fundamentally a perfect correlation between electrochemistry and thin film fields, but also significantly promotes larger-scale application of lithium-sulfur and lithium-air batteries, as well as other metal batteries (e...

Manganese dioxide nanomaterials with "Koosh-ball" like morphology (MnO2-KBs) as well as worm-like nanotubes (MnO2-NWs) were obtained by employing Tween 20 as the reducing-cum-structure-directing agent, and KMnO4 as a MnO2 precursor. While the MnO2-KBs were interconnected with each other through tubular extensions, MnO2-NWs were largely disconnected. Both MnO2-KBs and MnO2-NWs had large BET surface areas (>200 m2/g), and were thermally robust upto 300 ⁰C. The electrochemical studies revealed that the highest specific capacitance (Csp) obtained for MnO2-KBs was significantly higher (272 F/g) than that of MnO2-NWs (129 F/g)...
