Abdominal aortic aneurysms (AAAs), which commonly occur among elderly individuals, are accompanied by a risk of rupture with a high mortality rate. Although eicosapentaenoic acid (EPA) has been reported to prevent AAA formation, the mechanism by which EPA works on vascular smooth muscle cells is unknown. This study aimed to investigate the mechanism by which orally-administered EPA prevents the formation of severe AAAs that develop in Osteoprotegerin (Opg) knockout (KO) mice. In the CaCl2-induced AAA model, EPA attenuated the enhanced progression of AAAs in Opg-KO mice, including the increase in aortic diameter with destruction of elastic fibers in the media...

A cobalt-rhodium heterobimetallic nanoparticle-catalyzed reductive cyclization of 2-(2-nitroaryl)acetonitriles to indoles has been achieved. The tandem reaction proceeds without any additives under the mild conditions (1 atm H2 and 25 °C). This procedure could be scaled up to the gram scale. The catalytic system is significantly stable under these reaction conditions and could be reused more than ten times without loss of catalytic activity.

Thiomaltol, a potential S,O-coordinating molecule, has been utilized for the complexation of four different organometallic fragments, yielding the desired Ru(II) , Os(II) , Rh(III) , and Ir(III) complexes having a "piano-stool" configuration. In addition to the synthesis of these compounds with a chlorido leaving group, the analogous 1-methylimidazole derivatives have been prepared, giving rise to thiomaltol-based organometallics with enhanced stability under physiological conditions. The organometallic compounds have been characterized by NMR spectroscopy, elemental analysis, and X-ray diffraction analysis...

Resonant x-ray scattering (RXS) has recently become an increasingly important tool for the study of ordering phenomena in correlated electron systems. Yet, the interpretation of RXS experiments remains theoretically challenging because of the complexity of the RXS cross section. Central to this debate is the recent proposal that impurity-induced Friedel oscillations, akin to quasi-particle interference signals observed with a scanning tunneling microscope (STM), can lead to scattering peaks in RXS experiments...

We report the partial core-shell nanowire motors. These nanowires are fabricated using our previously developed electrodeposition-based technique, and their catalytic locomotion in the presence of H2O2 is investigated. Unlike conventional bimetallic nanowires that are self-electroosmotically propelled, our Au/Ru core-shell nanowires show both a noticeable decrease in rotational diffusivity and increase in motor speed with nanowire length. Numerical modelling based on self-electroosmosis attributes the decreases in rotational diffusivity to the formation of toroidal vortices at the nanowire tail, but fails to explain the speed increase with length...

Treatment of [M2 (μ-Cl)2 (cod)2 ] (M=Ir and Rh) with Na[H2 B(bt)2 ] (cod=1,5-cyclooctadiene and bt=2-mercaptobenzothiazolyl) at low temperature led to the formation of dimetallaheterocycles [(Mcod)2 (bt)2 ], 1 and 2 (1: M=Ir and 2: M=Rh) and a borate complex [Rh(cod){κ(2) -S,S'-H2 B(bt)2 }], 3. Compounds 1 and 2 are structurally characterized metal analogues of 1,5-cyclooctadiene. Metal-metal bond distances of 3.6195(9) Å in 1 and 3.6749(9) Å in 2 are too long to consider as bonding. In an attempt to generate the Ru analogue of 1 and 2, that is [(Rucod)2 (bt)2 ], we have carried out the reaction of [Ru(Cl)2 (cod)(CH3 CN)2 ] with Na[H2 B(bt)2 ]...

OBJECTIVE: The Moens-Korteweg equation predicts changes in pulse wave velocity (PWV) following changes in arterial radius, therefore an increase in arterial radius, as seen in a reactive hyperaemia (RH) condition, should slow PWV over a given arterial segment. If this assumption is true, than the deceleration of PWV over the brachial artery (flow-mediated slowing - FMS) should be an equivalent signal of endothelial function during a conventional RH flow-mediated dilation (FMD) procedure...

OBJECTIVE: Multiple medication use in patients with hypertension (HTN) is a common clinical problem faced by both primary and specialists. Patients who remain to have higher BP in spite of the concurrent use of 3 antihypertensive agents of different classes are defined as resistant hypertension (RH). In the study we aimed to identify the prevalence of RH, and examined its association with mortality from all-cause and cardiovascular disease (CVD). DESIGN AND METHOD: Data from the U...

OBJECTIVE: Recent evidence points to the effectiveness of spironolactone vs placebo in the treatment of resistant hypertension (RH). However, placebo is rarely a realistic treatment choice in uncontrolled hypertension. Using meta-analysis, we assessed the effectiveness of alternative 4 line anti-hypertensive agents in comparison to 4 line spironolactone/eplenerone in RH. DESIGN AND METHOD: Pubmed, EMBASE and the Cochrane library were systematically searched for randomised and non-randomised studies that compared any 4 line anti-hypertensive agent to spironolactone/eplenerone in RH...

The photochemical reaction of piperazine with C70 produces a mono adduct (N(CH2CH2)2NC70) in high yield (67%) and three bis-adducts. These adducts combine with Lewis acids to form crystalline aggregates suitable for X-ray diffraction. The structure of (N(CH2CH2)2NC70) was determined from the adduct that formed by reaction of N(CH2CH2)2NC70 with I2. Crystals of polymeric {Rh2(O2CCF3)4N(CH2CH2)2NC70}n*nC6H6 from reaction of the mono adduct with Rh2(O2CCF3)4 contain a sinusoidal strand of alternating molecules of N(CH2CH2)2NC70 and Rh2(O2CCF3)4 connected through Rh-N bonds...

The evaluation of the transplanted liver health by non-invasive approaches may offer an improvement in early clinical intervention. As transplanted organs have genomes that are distinct from the host's genome, the quantification of the specific DNA of the donated liver in the patient serum will allow us to obtain information about its damage. We evaluated the state of transplanted liver health by monitoring the RH gene in serum circulating DNA (cirDNA) from 17 recipient and donor mismatched for this gene. cirDNA RH gene was quantified by RT- PCR before, at the moment of transplantation (day 0) and during the stay at the intensive care unit...

Photocatalytic overall water splitting requires co-catalysts, which efficiently promote the generation of H2, but do not catalyze its reverse oxidation. We demonstrate, that CO chemisorbed on metal co-catalysts (Rh, Pt, Pd) suppresses the back reaction, while maintaining the rate of H2 evolution. On Rh/GaN:ZnO, the highest H2 production rates were obtained with 4 - 40 mbar CO, the back reaction remaining suppressed below 7 mbar O2. The O2 and H2 evolution rates compete with CO oxidation and the back reaction...
