One-step synthesis of porous bimetallic PtCu nanocrystals with high electrocatalytic activity for methanol oxidation reaction (2015)

The design of porous bimetallic nanocrystals (NCs) is very important for electrochemical energy conversion. Herein, we report an aqueous solution method for one-step fabrication of porous PtCu NCs assembled by spatially interconnected arms in high yield by a simple ultrasonic treatment of the reaction mixture at room temperature. The proposed method, without the need for multi-step synthesis, high temperatures, and organic solvents, shows an obvious advantage of simplicity for the feasible synthesis of bimetallic PtCu NCs with a porous structure. The as-made porous PtCu NCs are highly active and durable catalysts for the methanol oxidation reaction due to their porous structure and bimetallic composition.
Inhibition of In-vitro Lymphocyte Transformation by the Isoquinoline Alkaloid Berberine (1995)

Berberine is an isoquinoline alkaloid with multiple pharmacological actions, including an anti-inflammatory activity. The effects of berberine on in-vitro cellular proliferation of human peripheral lymphocytes stimulated with phytohaemagglutinin, concanavalin A and pokeweed mitogen were studied. Mononuclear cells were cultured in flat-bottomed 96-well microplates at 37 degrees C for 96-144 h in the presence of one mitogen at different concentrations and the alkaloid at doses of 2.5 to 20 microg mL-1. The mitogen-induced response of lymphocytes was evaluated from the extent of the incorporation of [3H]thymidine into cells in-vitro. A consistent and progressive inhibitory influence of berberine with increasing concentrations in culture was identified with all mitogens and was more pronounced with pokeweed mitogen. The effect of berberine was observed in phytohaemagglutinin (PHA)-and concanavalin A-activated lymphocytes when the drug was added during the first 24 h of culture, whereas the same effect occurred throughout the incubation period in pokeweed mitogen-stimulated cells. The viability of lymphocytes following treatment with the drug, as assessed by the trypan blue exclusion test, revealed no change when compared with the same untreated lymphocytes, indicating no lymphocytotoxic activity. We conclude that some effects of berberine, especially its anti-inflammatory action, may arise in part from the inhibition of DNA-synthesis in activated lymphocytes.
A Frequency Tunable High Sensitivity H-Field Probe Using Varactor Diodes and Parasitic Inductance (2015)

A frequency-tunable resonant magnetic field probe is designed for near-field scanning applications for the radio frequency interference studies. Tunable resonance is achieved by using a varactor diode providing the required capacitance and the parasitic inductance of a magnetic loop (i.e., a parallel LC circuit). An equivalent circuit model for the probe is described, analyzed, and used for designing the probe for achieving maximum sensitivity. The resonance frequency of the designed probe is tunable in the frequency range of 900-2260 MHz that covers multiple radio bands, such as the GSM900, UMTS, and GPS bands. The sensitivity of the probe at the resonance frequency is about 7-9 dB higher than that of an equivalently sized broadband magnetic field probe throughout the tunable frequency range. The measured frequency response and sensitivity over a microstrip trace using the fabricated probe shows good agreement with the simulated results of the equivalent circuit model and the full-wave simulation model.

Hot Defluorination of Reducing Gases with Lime Pellets (2000)

In IGCC and MCFC power generation systems the coal gas has to be purified from dust and deleterious gaseous species. Hot gas cleaning processes have advantages compared to conventional wet cleaning technologies. Losses of energy occurring during cooling and reheating of the gas can be avoided, and there is no formation of a wet slurry. In the present study the defluorination of reducing gases with dry absorbers such as calcium carbonate (CaCO3) and calcium oxide (CaO) has been investigated in the temperature range 300−700 °C. Two types of experiments were carried out to clarify the reaction kinetics: thermogravimetric experiments on single (or a few) pellets in which the weight change of the absorber due to its conversion to calcium fluoride was determined, and gas cleaning experiments using a laboratory scale fixed bed reactor in which the off-gas was analyzed. The results indicate that H2−H2O−HF and CO−H2−CO2−H2O−HF gas mixtures can be defluorinated both with CaO and with CaCO3. The calcium fluoride (CaF2) forms as a shell around the unreacted core of calcium carbonate of the pellet, and the reaction rate is mainly controlled by gaseous pore diffusion. This is so also with respect to calcium oxide at high temperatures (500 °C). But at low temperatures (300 °C) the reaction occurs within the bulk of the pellet.
Abstract 13520: Empagliflozin Reduces Markers of Arterial Stiffness, Vascular Resistance and Cardiac Workload in EMPA-REG OUTCOME (2016)

Introduction: In EMPA-REG OUTCOME ® , empagliflozin added to standard of care in patients with type 2 diabetes and established vascular disease, significantly reduced the primary composite outcome of CV death, non-fatal myocardial infarction or non-fatal stroke, a result driven mainly by a 38% reduction in CV death. We aimed to assess the vascular effects of empagliflozin in the trial, beyond its recognized effects in reducing systolic blood pressure (SBP) and diastolic BP (DBP). Hypothesis: We hypothesized that empagliflozin reduced 1) pulse pressure (PP), a vascular marker of arterial stiffness determined by the cardiac output, the stiffness of elastic central arteries and wave reflection (PP = SBP - DBP), 2) mean arterial pressure (MAP), a measure reflecting the cardiac cycle determined by the cardiac output, systemic vascular resistance, and central venous pressure (MAP = ([2 x diastolic BP]+ systolic BP)/3), and 3) the double product (DP), a marker of cardiac workload and an indirect measure of myocardial oxygen demand (DP = heart rate x SBP). Methods: Patients with type 2 diabetes and high CV risk were randomised to receive placebo, empagliflozin 10 mg, or empagliflozin 25 mg in addition to standard of care. We analysed changes from baseline to week 164 for SBP, DBP, HR, PP, MAP and DP, between treatment and placebo groups using a mixed model repeated measures analysis. Results: In total, 2333, 2345 and 2342 patients received placebo, empagliflozin 10 mg and empagliflozin 25 mg, respectively and followed for a median period of 3.1 years. There were nominal significantly greater reductions in PP, MAP and DP with empagliflozin treatment as compared with placebo (Table), without increases in mean HR (Table). Conclusions: Empagliflozin had favorable effects on BP, arterial stiffness, vascular resistance and on the indirect measure of cardiac workload. Further analyses are needed to determine the potential contribution of these changes to the reduction in CV mortality.
Experiments on high rate effluent filtration in the Netherlands (1998)

As yet, filtration of wastewater treatment effluent has not been practised in the Netherlands. The main objections were the expected high costs. In order to gain practical experience an investigation programme studied the applicability and optimization of effluent filtration. Especially multi-layer filtration with the addition of ironchloride seemed to be very effective. Very low concentrations of suspended solids and phosphorus were achieved, even at high filtration rates (up to 30 m/h). This leads to an impressive reduction of expected costs, down to Dfl. 0.02/m3 (treated water).
Holographic Photopolymerization-Induced Phase Separation in Reference to the Phase Diagram of a Mixture of Photocurable Monomer and Nematic Liquid Crystal (2005)

Theoretical investigation on pattern photopolymerization has been undertaken in various coexistence regions of a mixture of photocurable monomer and nematic liquid crystal. The phase diagram of the mixtures is constructed in accordance with a combined Flory−Huggins (FH) free energy of isotropic mixing and the Maier−Saupe (MS) free energy of nematic ordering. The pattern formation dynamics of holographic photopolymerization has been explored in conjunction with the phase diagram of the starting mixture of monomer and nematic liquid crystal. To mimic the evolution of holographic structure, the combined FH and MS free energy is incorporated into the time-dependent Ginzburg−Landau (model C) equations coupled with the photopolymerization kinetic equation. The morphology evolution and mechanisms have been investigated in relation to the situations whether the system should remain in the single phase after photopolymerization or be thrust into the two-phase region. Of particular significance is that the diffraction efficiency (DE) of gratings, a key property in electrooptical applications, can be monitored in-situ during photopatterning. In the gratings of inhomogeneous structures, scattering occurs due to the interparticle interference, which needs to be accounted for in the evaluation of the DE. A fast Fourier transformation (FFT) technique of the emerging morphological domains of the holographic polymer dispersed liquid crystals uniquely provides the simultaneous determination of the diffraction peaks from the holographic layers as well as scattering from the internal LC domains; thereby, the DE correction is feasible. The simulated patterns and the trends of diffraction efficiency evolution are compared with experimental observations.

The energy dependence of the reorientation effect has been investigated using ${\mathrm{O}}^{16}$ and ${\mathrm{S}}^{32}$ ions incident on ${\mathrm{Fe}}^{56}$ nuclei. The influence of nuclear interference on the reorientation effect was observed before it could be detected on the elastic cross section, and exhibited an angular dependence similar to that expected for the reorientation effect. It was found that an appropriate separation of projectile and target nuclei was given by $2a={R}_{0}({{A}_{1}}^{\frac{1}{3}}+{{A}_{2}}^{\frac{1}{3}})+\ensuremath{\Delta}$, where ${R}_{0}=1.6$ fm and $\ensuremath{\Delta}\ensuremath{\ge}3.5$ fm. The static quadrupole moment of the 0.847-MeV ${2}^{+}$ state in ${\mathrm{Fe}}^{56}$ was measured to be ${Q}_{22}=\ensuremath{-}0.23\ifmmode\pm\else\textpm\fi{}0.03 \mathrm{b}$, while the rotational value is given by $|{Q}_{R}|=0.276 \mathrm{b}$.
New concepts in liver regeneration (2011)

The unique ability of the liver to regenerate itself has fascinated biologists for years and has made it the prototype for mammalian organ regeneration. Harnessing this process has great potential benefit in the treatment of liver failure and has been the focus of intense research over the past 50 years. Not only will detailed understanding of cell proliferation in response to injury be applicable to other dysfunction of organs, it may also shed light on how cancer develops in a cirrhotic liver, in which there is intense pressure on cells to regenerate. Advances in molecular techniques over the past few decades have led to the identification of many regulatory intermediates, and pushed us onto the verge of an explosive era in regenerative medicine. To date, more than 10 clinical trials have been reported in which augmented regeneration using progenitor cell therapy has been attempted in human patients. This review traces the path that has been taken over the last few decades in the study of liver regeneration, highlights new concepts in the field, and discusses the challenges that still stand between us and clinical therapy.

Antibodies against polyalanyl determinants attached to negatively or positively charged carriers (1971)

Abstract Polyalanyl determinants, when attached to acidic or basic carriers, provoke a specific anti‐polyalanyl antibody population, the majority of which possesses an electrical charge which is inversely related to that of the carrier. The alanine chains in the immunogens form complete determinants and the contribution of the carrier to the specificity of the antibodies is minimal. The anti‐polyalanyl antibodies, when fractionated into a more acidic and a more basic fraction, possess similar properties of their combining sites, as judged from hapten inhibition and equilibrium dialysis studies. Thus, the specificity of the antibodies and the combining site features are determined by the hapten determinants, whereas the net charge of the antibodies is determined by the net charge of the immunogen. The difference in the net electrical charge of the antibodies may reflect differences in areas of the molecule other than the combining site. A comparison of anti‐polyalanyl antibodies obtained with different carriers has shown that the specificity and size of the combining sites are similar regardless of the nature of the carrier molecule, whereas different affinities of the antibodies are obtained with different immunogens.
DISTINCT ALLOANTIGENS TRIGGER PROLIFERATIVE OR NONPROLIFERATIVE T LYMPHOCYTE ACTIVATION IN CBA/N, CBA/J, AND C3H MICE (1982)

Lymphokine release and proliferation take place during one-way murine mixed leukocyte cultures (MLCs) when responder and stimulator cells differ in H-2 alloantigens, whereas a dissociation of these two functions can be observed where there are incompatibilities in non H-2 alloantigens, It is possible that this dissociation depends on different thresholds of activation of the two responses, or that some non H-2 alloantigens selectively activate lymphokine release or proliferation. To investigate this question we used H-2-matched CBA/N, CBA/J. C3H/HN, (CBA/N x CBA/J)F1, and (CBA/N x C3H/HN)F1 leukocytes, both as responder and stimulator cells. CBA/N mice and the male F1 hybrids obtained from CBA/N mothers carry an X-linked immune defect that results in an arrest of B lymphocyte maturation. In the majority of MLC combinations tested, migration inhibition factor (MIF) release and proliferation took place in parallel. However, CBA/N, but not F1 leukocytes, stimulated MIF release and not proliferation by CBA/J responders, whereas C3H/HN leukocytes stimulated proliferative responses but not MIF release by CBA/J responders. Since proliferation and MIF release have a similar threshold of activation, their dissociation indicates that different non-H-2 alloantigens can specifically activate distinct T cell functions. Moreover, previously unsuspected alloantigen differences between CBA/N and CBA/J are revealed by MIF release.
Monellin (MNEI) at 1.15 Å resolution (2007)

The X-ray crystal structure of a single-chain monellin protein (MNEI) has been determined at 1.15 A resolution. The model was refined to convergence employing anisotropic displacement parameters and riding H atoms to produce a final model with R(work) and R(free) values of 0.132 and 0.162, respectively. The crystal contains a single MNEI protein in the asymmetric unit and unusually lacks the dimer interface observed in all previous crystal structures of monellin and its single-chain derivatives. The high resolution allowed a more detailed view of MNEI than previously possible, with 38 of the 96 residues modelled with alternative side-chain conformations, including four core residues Thr12, Cys41, Leu62 and Ile75. Four stably bound negative ions were also located, providing new insight into potential electrostatic interactions of MNEI with the largely negatively charged surface of the sweet taste receptor T1R2-T1R3.
Fluid resuscitation and hyperchloremic acidosis in experimental sepsis: Improved short-term survival and acid-base balance with Hextend compared with saline (2002)

Compared with 0.9% saline, volume resuscitation with Hextend was associated with less metabolic acidosis and longer survival in this experimental animal model of septic shock.
Estrogen Pharmacology. I. The Influence of Estradiol and Estriol on Hepatic Disposal of Sulfobromophthalein (BSP) in Man* (1964)

This report 1 describes the influence of natural estrogens on liver function, with special reference to sulfobromophthalein (BSP) excretion, in man. Pharmacological amounts of the hormone estradiol consistently induced alterations in BSP disposal that were shown, through the techniques of Wheeler and associates (2, 3), to result from profound depression of the hepatic secretory transport maximum (Tm) for the dye. Chromatographic analysis of plasma BSP components revealed increased amounts of BSP conjugates during estrogen as compared with control pe- riods, implying a hormonal effect on cellular proc- esses concerned with transport of dye from he- patocytes into biliary canaliculi. Estriol, an in vivo transformation product of estradiol, also im- paired hepatic disposal of BSP in man. Accord- ing to unpublished data of Hertz (4) 2 estrone, ethinyl estradiol, and equine estrogens act simi- larly, and it is likely that other C-18 steroids of both physiologic and synthetic origin have this property as well. These observations define a new
