BACKGROUND: The aim of this study was to investigate in vitro biocompatibility of Reguneal™, a new bicarbonate containing peritoneal dialysis fluid (PDF) for Japan, and compare it with other PDFs available in that country. METHODS: We assessed basal cytotoxicity using in vitro proliferation of cultured fibroblasts, L-929, determining the quantity of living cells by the uptake of Neutral Red. Levels of ten glucose degradation products (GDPs) were measured by a validated ultrahigh-performance liquid chromatography method in combination with an ultraviolet detector...

An array of heterobimetallic Pd/Ln MOFs (1-4) with Sm, Eu, Tb, Dy as preferred metal nodes and 1,1'-di(p-carboxybenzyl)-2,2'-diimidazole (H2L) as a fairly suitable bifunctional organic linker have been synthesized, fully characterized and tested as catalysts in cross-coupling reactions. These robust MOFs, ensuring a uniform distribution of Pd, showed excellent stability in air and high catalytic activity in Suzuki-Miyaura reactions conducted in neat water, neat ethanol as well as water-ethanol mixture. Depending on the solvent, complex 1 could be effectively recycled 4-8 times without significant loss of catalytic activity...

Acinetobacter baumannii appears as an often multidrug-resistant nosocomial pathogen in hospitals worldwide. Its remarkable persistence in the hospital environment is probably due to intrinsic and acquired resistance to disinfectants and antibiotics, tolerance to desiccation stress, capability to form biofilms, and is possibly facilitated by surface-associated motility. Our attempts to elucidate surface-associated motility in A. baumannii revealed a mutant inactivated in a putative DNA-(adenine N6)-methyltransferase, designated A1S_0222 in strain ATCC 17978...

We report the use of 2,6-dimethylphenyl isocyanide (2,6-DMPI) as a spectroscopic probe to study the heterogeneous nucleation and deposition of Pd on Ag nanocubes under different conditions by surface-enhanced Raman scattering (SERS). As a major advantage, the spectroscopic analysis can be performed in situ and in real time with the nanoparticles still suspended in the reaction solution. The success of this method relies on the distinctive stretching frequencies (νNC) of the isocyanide group in 2,6-DMPI when it binds to Ag and Pd atoms through σ donation and π-back donation, respectively...

We report a facile bottom-up synthetic approach to preparing ultrathin two-dimensional (2D) palladium nanosheets (PdNSs) with selectively exposed surface facets. Our synthetic strategy is based on the utilization of the nanoconfined lamellar mesophases of amphiphilic functional surfactants to template the growth of PdNSs in aqueous solution. Preferential adsorption of functional groups ( e.g. , COOH, pyridyl and quaternary ammonium) and halide counter ions ( e.g. , Br- and Cl- ) in the long-chain surfactants onto different Pd planes results in the epitaxial growth of {100}, {110} and {111}-exposed surface facets of ultrathin PdNSs...

Corbicula fluminea, an Asian clam, is one of the worst invasive species in Europe that can survive in very adverse environmental conditions. Despite its negative impacts, the species also has the capacity to bioaccumulate heavy metals, contaminants and can be exploited for wastewater treatment purposes. The capacity of the Asian clam to remove Escherichia coli, used as fecal contamination indicator, was analyzed. Conventional wastewater treatment plants are not suitable to remove bacteria, thus resulting in treated municipal wastewater with high bacterial loads...

The heterotrimetallic complexes [FeMFe(dpa)4Cl2] (M = Ni (1), Pd (2) and Pt (3); dpa- = dipyridylamido) featuring two high-spin iron centers linked by group 10 metals were synthesized and their physical properties were investigated. Oxidation of 1-3 with suitable oxidants in CH2Cl2 solution yielded mixed-valent [1]+/2+-[3]+/2+ species. The solution properties of [1]0/+/2+-[3]0/+/2+ were characterized by 1H NMR spectroscopy, UV-vis-NIR spectroscopy and spectroelectrochemisty. The mixed-valent states on [1]+-[3]+ obtained by electrochemical or chemical oxidation are classified as class II valence delocalization...

Self-assembly of a cis-blocked Pd(II) 90 ditopic acceptor [cis-(tmeda)Pd(NO3)2] (M) with a tetradentate donor L1 [benzene-1,4-di(4-terpyridine)] in 2:1 molar ratio yielded two isometric molecular barrels MB1 and MB3 in DMSO [tmeda = N,N,NN-tetramethylethane-1,2-diamine]. Exclusive formation of the symmetrical tetrafacial barrel (MB1) was achieved when the self-assembly was performed in aqueous medium. The presence of a large confined cavity makes MB1 as a potential molecular container. Spiropyran (SP) compounds exist in stable closed spiro-form in visible light and converts to transient open merocyanine (MC) form upon irradiation with UV-light or upon strong heating...

Selective copper(I) to palladium(0) transmetallation of P-donors from the rigid N,N'-diphosphanyl-imidazol-2-ylidene C3 H2 [NP(tBu)2 ]2 (PCNHC P) was observed when known [Cu3 (μ3 -PCNHC P,κP,κCNHC ,κP)2 ](OTf)3 was reacted with [Pd(PPh3 )4 ]. When 1.2 equivalents of [Pd(PPh3 )4 ] was used, the product [Cu2 Pd(μ3 -PCNHC P,κP,κCNHC ,κP)2 ](OTf)2 (2(OTf)2 ) was obtained, which features a CuI -CuI -Pd0 chain and appears to be the first linear heterotrinuclear complex with d10 -d10 interactions between Pd0 and CuI ...

Peritoneal membrane failure due to fibrosis limits the use of peritoneal dialysis (PD). Peritoneal fibrosis may potentially be induced by sterile inflammation caused by ongoing cellular stress due to prolonged exposure to PD solutions (PDS). Effective therapies to prevent this process remain to be developed. Toll-like receptors (TLRs) mediate sterile inflammation by recognizing damage-associated molecular patterns (DAMPs) released by cellular stress. We evaluated the involvement of TLRs and DAMPs in PDS-induced fibrosis models and the therapeutic potential of TLR-DAMP targeting for preventing fibrosis...

Coping with the transition from end-stage kidney disease to dialysis can be challenging for patients and their care partners. Introducing incident dialysis patients to incremental forms of dialysis is associated with better quality of life and reduced cost. Incremental hemodialysis (HD) has generated significant interest over the last decade with treatments that focus on clinical criteria rather than prespecified Kt/Vurea targets. Incremental peritoneal dialysis (PD) has traditionally focused on the sum of residual renal and peritoneal clearances to achieve a specific Kt/Vurea value...

A novel composite bimetallic electrode, palladium-nickel/multi-walled carbon nanotubes/graphite felt (Pd-Ni/MWCNTs/GF), was synthesized for the electrocatalytic hydrodechlorination of 4-chlorophenol (4-CP). GF with a three-dimensional structure was used as the electrode substrate, and doped with MWCNTs, which can improve the GF conductivity and serve as a skeleton for metal loading. Ni and Pd were deposited on the electrode surface stepwise to obtain a well-aligned, highly active and stable Pd-Ni/MWCNTs/GF electrode...

BACKGROUND: Acute kidney injury (AKI) is common in low- and middle-income countries, and is associated with a high mortality. The high mortality rate is in large part due to the inability to perform dialysis in resource-limited settings. Due to significant cost advantages, peritoneal dialysis (PD) has been used to treat AKI in these settings. The costs, however, remain high when commercial solutions are used. METHODS: This is a retrospective cohort study of the outcome, and of the peritonitis rates, of patients with AKI treated with either commercially manufactured PD solutions or locally-made PD solutions...

Neurodegenerative diseases, such as Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD) and amyotrophic lateral sclerosis (ALS), affect millions of people every year and so far, there are no therapeutic cures available. Even though animal and histological models have been of great aid in understanding disease mechanisms and identifying possible therapeutic strategies, in order to find disease-modifying solutions there is still a critical need for systems that can provide more predictive and physiologically relevant results...

Pd-CeOx solid solutions have demonstrated promising performance in industrial and environmental catalysis. However, challenges such as severe growth and aggregation of Pd and thermal-, vapor- or SO2-induced poisoning still obstruct their path toward real-world applica-tions. Herein we develop an efficient strategy (enhanced metal-oxide interaction and core-shell confinement to inhibit the sintering of noble metal) for design and synthesis of confined ultrathin Pd-CeOx nan-owire (2.4 nm) catalysts for methane combustion, which enable CH4 total oxidation at a low temperature of 350C, much lower than that (425C) of a commercial Pd/Al2O3 catalyst...

This paper investigates the concepts, performance and limitations of temperature sensing circuits realized in complementary metal-oxide-semiconductor (CMOS) silicon on insulator (SOI) technology. It is shown that the MOSFET threshold voltage ( Vt ) can be used to accurately measure the chip local temperature by using a Vt extractor circuit. Furthermore, the circuit's performance is compared to standard circuits used to generate an accurate output current or voltage proportional to the absolute temperature, i...
