Mechanism of the lifespan extension of Caenorhabditis elegans by electrolyzed reduced water--participation of Pt nanoparticles. (7/11)Electrolyzed reduced water (ERW) contains a large amount of molecular hydrogen and a small amount of Pt nanoparticles (Pt NPs). We have found that ERW significantly extended the lifespan of Caenorhabditis elegans in a novel culture medium designated Water Medium. In this study, we found that synthetic Pt NPs at ppb levels significantly extended the nematode lifespan and scavenged reactive oxygen species (ROS) in the nematode induced by paraquat treatment. In contrast, a high concentration of dissolved molecular hydrogen had no significant effect on the lifespan of the nematode. These findings suggest that the Pt NPs in ERW, rather than the molecular hydrogen, extend the longevity of the nematode, at least partly by scavenging ROS. (+info)

Bill Costerton - University of Copenhagen
Dr Costerton pioneered the development of the biofilm theory of which bacteria grow enclosed in a protective, biopolymeric matrix forming a film that is adherent to solid surfaces (a sessile organism). Together with University of Copenhagens Dr. Niels Høiby, he strongly promoted the view that bacteria in biofilms differ from their planktonic (free-floating) counterparts (Costerton et al., Sci Am 1978).. Dr Costerton published over 700 peer-reviewed papers that provide a solid basis for the understanding of bacterial processes in environmental, dental and medical microbiology. The research led to many industrial and medical relevant breakthroughs, confirming that biofilms cause chronic infections and biofilm implant-related infections represent one of the most difficult-to-treat infections in humans.. Dr John William Costerton died on 12 May 2012.. ...

Protein targeting by the bacterial twin-arginine translocation (Tat) pathway. - Oxford Neuroscience
The Tat (twin-arginine translocation) protein export system is found in the cytoplasmic membrane of most prokaryotes and is dedicated to the transport of folded proteins. The Tat system is now known to be essential for many bacterial processes including energy metabolism, cell wall biosynthesis, the nitrogen-fixing symbiosis and bacterial pathogenesis. Recent studies demonstrate that substrate-specific accessory proteins prevent improperly assembled substrates from interacting with the Tat transporter. During the transport cycle itself substrate proteins bind to a receptor complex in the membrane which then recruits a protein-translocating channel to carry out the transport reaction.
trans-translation in mycobacteria: expression, regulation, and the effects of ribosome inhibitors :: University of Southern...
Unique bacterial process, trans-translation, has been studied to be an important process in many bacteria. However, there was nothing known about the significance of this process in mycobacteria, especially in relation to drug susceptibility. Consistent with findings in Escherichia coli, Salmonella typhimurium, and Synechocystis sp., we found that interfering with the expression of tmRNA and the smpB gene (critical components of trans-translation) in Mycobacterium smegmatis caused increased bactericidal activity of antimicrobial agents that target the ribosomes. Moreover, exposure to ribosome inhibitors increased the expression of tmRNA. This increase was driven by the tmRNA gene promoter which activity seemed to utilize a de-repression mechanism. Not only is trans-translation important to the bacterial response to ribosome inhibitors, evidence from this laboratory suggests that trans-translation is essential in mycobacteria. Thus, we believe that trans-translation may represent a new important ...

This paper examined the local structural properties of Pt nanoparticles on SiO 2, TiO 2-SiO 2, and ZrO 2-SiO 2 supports to better understand the impact of oxide-support type on the performance of Pt-based catalysts. In situ X-ray absorption fine structure (XAFS) measurements were taken for the Pt L3-edge in a temperature range from 300 to 700 K in He, H 2, and O 2 gas environments. The XAFS measurements demonstrated that Pt atoms were highly dispersed on TiO 2-SiO 2 and ZrO 2-SiO 2 forming pancake-shaped nanoparticles, whereas Pt atoms formed larger particles of hemispherical shapes on SiO 2 supports. Contrary to the SiO 2 case, the coordination numbers for Pt, Ti, and Zr around Pt atoms on the TiO 2-SiO 2 and ZrO 2-SiO 2 supports were nearly constant from 300 to 700 K under the different gas environments. These results are consistent with the improvements in thermal stability of Pt nanoparticles achieved by incorporating TiO 2 or ZrO 2 on the surface of SiO 2 supports. XAFS analysis further ...

The oral pathogen Tannerella forsythia possesses a unique surface (S-) layer with a complex O-glycan containing a bacterial sialic acid mimic in the form of either pseudaminic acid or legionaminic acid at its terminal position. We hypothesize that different T. forsythia strains employ these stereoisomeric sugar acids for interacting with the immune system and resident host tissues in the periodontium. Here, we show how T. forsythia strains ATCC 43037 and UB4, displaying pseudaminic acid and legionaminic acid, respectively, and selected cell surface mutants of these strains, modulate the immune response in monocytes and human oral keratinocytes (HOK) using a multiplex immunoassay ...

The methanol oxidation reaction (MOR) and related carbon monoxide (CO) oxidation reaction (COR) activities on the synthesized cubic and octahedral/tetrahedral (O/T) Pt nanoparticles (NPs) still having residual polyvinylpyrrolidone (PVP) were investigated using electrochemical (EC) and in situ Fourier transform infrared (FT-IR) spectroscopic measurements in both 0.1 M HClO4 and 0.1 M H2SO4. While EC measurements confirmed the enhanced MOR activity on the O/T Pt NPs as observed previously (Susut et al., Phys. Chem. Chem. Phys. 10:3712, 6), the in situ IR measurements showed much improved data quality as compared to the previous studies and provided strong indications that the underlying reason for the observed MOR enhancement on the O/T Pt NPs was highly likely related to the enhanced no-CO-generating reaction pathway(s), as evidenced by much lower CO generation during the MOR on these Pt NPs ...

VIRTUAL GRAND ROUNDS IN DERMATOLOGY 2.0: September 2011
Diagnosis: Although initially I was concerned about a bacterial lymphangitis, I now think this is most consistent with lymphangitis secondary to insect bite rather than a sign of a bacterial etiology. Yeat knows the initial lesions are bites and he feels well otherwise. I suppose a bite could have been superinfected with strep, so the Augmentin makes sense; but it could also be based on another mechanism. There are a few pertinent references including one from the BMJ which Mr. Yeat found (# 2). I am not convinced this is from bedbugs as many types of arthropod bites apparently can cause lymphangitis. Its curious that so few cases have been reported. This may be because the patients appear to have a bacterial process, are treated with antibiotics and get better as they would over a few days even without the medications. It would be important to know if bed bugs have been found in his dormitory ...
PLOS ONE: Kinetic Analysis of Yersinia pestis DNA Adenine Methyltransferase Activity Using a Hemimethylated Molecular Break...
BackgroundDNA adenine methylation plays an important role in several critical bacterial processes including mismatch repair, the timing of DNA replication and the transcriptional control of gene expression. The dependence of bacterial virulence on DNA adenine methyltransferase (Dam) has led to the proposal that selective Dam inhibitors might function as broad spectrum antibiotics.Methodology/Principal FindingsHerein we report the expression and purification of Yersinia pestis Dam and the development of a continuous fluorescence based assay for DNA adenine methyltransferase activity that is suitable for determining the kinetic parameters of the enzyme and for high throughput screening against potential Dam inhibitors. The assay utilised a hemimethylated break light oligonucleotide substrate containing a GATC methylation site. When this substrate was fully methylated by Dam, it became a substrate for the restriction enzyme DpnI, resulting in separation of fluorophore (fluorescein) and quencher (dabcyl)

The presence of Escherichia coli (E. coli) in food and drinking water is a chronic problem worldwide. Protecting food against bacterial contamination and rapid diagnosis of infection require simple and rapid assays for detection of bacterial pathogens, including E. coli O157:H7. Here we report a rapid and novel colorimetric method for detecting E. coli O157:H7. This colorimetric method is based on the catalytic oxidation of the peroxidase substrate 3,3,5,5-tetramethylbenzidine by hydrogen peroxide using 4-mercaptophenylboronic acid-functioned [email protected] nanoparticles adsorbed on the surface of E. coli O157:H7. The assay showed excellent sensitivity both with the naked eye and based on absorbance measurements. The absorbance at 652 nm was proportional to the concentration of E. coli O157:H7 ranging from 7 to 6 × 10(6) cfu mL(-1) with a limit of detection of 7 cfu mL(-1). The total detection time was less than 40 min.

Microbiology Society Journals | A putative DNA adenine methyltransferase is involved in Yersinia pseudotuberculosis...
Some adenine methyltransferases have been shown not only to protect specific DNA restriction sites from cleavage by a restriction endonuclease, but also to play a role in various bacterial processes and sometimes in bacterial virulence. This study focused on a type I restriction-modification system (designated yrmI) of Y. pseudotuberculosis. This system is composed of three adjacent genes which could potentially encode an N 6-adenine DNA methylase (YamA), an enzyme involved in site-specific recognition (YrsA) and a restriction endonuclease (YreA). Screening of 85 isolates of Y. pestis and Y. pseudotuberculosis indicated that the yrmI system has been lost by Y. pestis and that yamA (but not yrsA or yreA) is present in all Y. pseudotuberculosis strains tested, suggesting that it may be important at some stages of the epidemiological cycle of this species. To further investigate the role of yamA in Y. pseudotuberculosis survival, multiplication or virulence, a ΔyamA mutant of Y. pseudotuberculosis IP32953

Monodispersed Pt nanoparticles supported on a TiO2 and nitrogen-doped carbon composite (TiO2/NDC) were successfully synthesized via an efficient in situ self-assembly strategy and microwave-assisted polyol process. The Pt/TiO2/NDC catalyst exhibited superior electrocatalytic activity toward the methanol oxidation reaction (MOR). The electrochemically active surface area of the Pt/TiO2/NDC catalyst was twofold higher than that of the Pt/C/NDC catalyst. In addition, the Pt/TiO2/NDC catalyst revealed a better electrocatalytic activity and CO-tolerance as well as a stability toward the MOR. The combined characterization from Fourier transform infrared spectrum, Brunauer-Emmett-Teller surface area, scanning electron microscopy, transmission electron microscopy, energy dispersive spectrometer, thermogravimetric analysis, inductively coupled plasma atomic emissions spectrometry, X-ray diffraction, and X-ray photoelectron spectroscopy analyses demonstrated that the superior catalytic performance and ...

Frontiers | Kinetic Insight on Improved Chemi-Resistive Response of Hydrothermal Synthesized Pt Loaded TiO2 Nano-rods Toward...
Flower like microstructure composed of eccentrically grown vertically aligned titania nano-rods is prepared through spherical carbon template mediated hydrothermal route. Mechanistic pathways for the growth of said esthetic architecture is proposed by studying their phase formation behavior and morphological features. Chemi-resistive type sensing properties of prepared titania flowers for the detection of isopropanol are studied by varying the sensor operating temperature (225-300°C) and vapor concentration (10-200 ppm). Distinguishable sensitivity of titania flowers is identified for the detection of even 10 ppm isopropanol. Catalytic amount of Pt nano-particles (synthesized through chemical method) are introduced over prepared flower like titania to improve further their sensitivity. The plausible isopropanol sensing mechanism over TiO2 flowers as well as influence of operating temperature and role of Pt nanoparticles as chemical sensitizer in enhancing the response is explained.

HI ERN - EEC - Two papers on particle size effect on platinum dissolution
Proton exchange membrane fuel cells (PEMFC) suffer from high cost of the state of the art platinum catalyst. The PEMFC costs can be reduced by decreasing the size of Pt nanoparticles in the catalyst layer, thereby increasing the Pt dispersion and utilization. However, firm conclusions on how Pt particle size impacts durability remain elusive due to synthetic difficulties in exclusively varying single parameters (e.g., particle size and loading). To address these issues, two model systems were synthesized and studied in collaboration with Prof. Arenz and Prof. Chorkendorff groups. 2D system was prepared by depositing mass-selected nanoparticles on a flat glassy carbon substrate using magnetron sputtering. Pt particle diameter was varied from 2 to 10 nm. A complex interplay between dissolution and passivation processes (both depend on particle size) was identified. As for 3D system, the particle size of Pt nanoparticles was varied from 2.0 to 2.8 and 3.7 nm while keeping the loading constant (30 ...
science24.com - New strategies in the electroctalytic reduction of oxygen for fuel and biofuel cells
Platinum has been established as the most powerful electrocatalyst for the 4-electron reduction of oxygen to water in acid medium in a conventional fuel cell. The reaction becomes less efficient and its efficiency suffers from the formation of the hydrogen peroxide intermediate at lower Pt loadings or at higher current densities. Recent progress in the area concerns fabrication of electrocatalysts in a form of carbon-supported platinum nanoparticles assembled within organized multilayers or inks deposited on a proton-conducting membrane. Important issues include the stabilization of Pt nanoparticles (to prevent their agglomeration causing decrease of the active surface area), the enhancement of their reactivity (e.g. by modification of their surfaces or by formation of novel bimetallic systems), the interfacial protection of nanostructured Pt from poisoning (e.g. by the development of methanol or CO tolerant systems using Ru-Se nanoparticles), and the activation of metal nanoparticles through ...

DSpace at EWHA: The Surface-Imprinted Thermosensitive Core-Shell Nanosphere
The molecular imprinting techniques have been extensively studied for molecular recognition and their potential applications to separation and catalysis. The traditional imprinting method uses the crosslinking polymerization in the presence of a substrate molecule followed by grinding the bulk system to microparticles with an irregular shape. In addition, the imprinting is restricted to a hydrophobic substrate because the polymerization reaction is usually done in the organic solvent using hydrophobic monomers. In this case, the irregular shape and microparticle size might be a concern for microelectromechanical system (MEMS) application as a biosensor. In this study, we investigated a well-defined nanosphere with a core-shell structure for molecular imprinting. The hydrophilic substrates including D-glucose (D-Glu) or L-phenylalanine (L-Phe) were imprinted on the surface (shell) of nanosphere and their binding behavior were investigated. Their enantiomer (L-Glu or D-Phe) binding behavior to the ...
Hollow Beta zeolites : synthesis and impact of the hollow morphology on diffusion and catalysis - TEL - Thèses en ligne
Hollow zeolite single crystals have received particular interest in catalysis. The presence of a large cavity in these model zeolites enables the study of diffusional limitation in Catalysis. The cavity also enables the encapsulation of metal nanoparticles. However, their synthesis requires specific structural characteristics and it has been limited for long to zeolites with the MFI structure. The objective of this PhD work was to investigate the synthesis of hollow Beta zeolites (*BEA framework type) and study the impact of the hollow morphology on molecular diffusion and catalysis. Two different strategies have been envisaged: a dissolution/recrystallization approach using CIT-6, a zincosilicate with the same *BEA topology and a selective desilication route. Pt nanoparticles encapsulated in hollow crystals obtained from CIT-6 showed remarkable size-selectivity in the hydrogenation of aromatics. The effect of the hollow morphology in molecular diffusion was studied using the ZLC technique; the

Microwave Decoration of Pt Nanoparticles on Entangled 3D Carbon Nanotube Architectures as PEM Fuel Cell Cathode - Sherrell -...
Proton-exchange membrane fuel cells (PEMFCs) are expected to provide a complementary power supply to fossil fuels in the near future. The current reliance of fuel cells on platinum catalysts is undesirable. However, even the best-performing non-noble metal catalysts are not as efficient. To drive commercial viability of fuel cells forward in the short term, increased utilization of Pt catalysts is paramount. We have demonstrated improved power and energy densities in a single PEMFC using a designed cathode with a Pt loading of 0.1 mg cm−2 on a mesoporous conductive entangled carbon nanotube (CNT)-based architecture. This electrode allows for rapid transfer of both fuel and waste to and from the electrode, respectively. Pt particles are bound tightly, directly to CNT sidewalls by a microwave-reduction technique, which provided increased charge transport at this interface. The Pt entangled CNT cathode, in combination with an E-TEK 0.2 mg cm−2 anode, has a maximum power and energy density of ...

Rational Catalyst Design for Direct Conversion of CH4 and CO2 by Vesna Havran Mueller
Possibilities for mitigation of carbon dioxide and methane levels in the atmosphere are of major global interest. One of the alternatives that attracts much scientific attention is their chemical utilization, especially because both of these gases are components of the natural gas, and rapid and extensive shale gas development makes them abundant raw materials. Development of an effective catalytic process that could be scaled-up for industrial purposes remains a great challenge for catalysis. Understanding of the mechanisms of molecular activation as well as of the reaction pathways over active centers on heterogeneous catalysts needs to be advanced. To that end this work focused on initiating the development of a bifunctional catalyst for low-temperature: 200C - 450C) direct conversion of methane and carbon dioxide by tailoring the structure of each active component using the insights from molecular modeling. Pt nanoparticles supported on ceria support have been selected based on molecular modeling
