Probiotics and antimicrobial proteins

De Vuyst L, Vincent P, Makras E, Leroy F, Pot B.
PMID: 26780898
Probiotics Antimicrob Proteins. 2010 Mar;2(1):26-36. doi: 10.1007/s12602-009-9029-4.

Helicobacter pylori inhibition by probiotic lactobacilli has been observed in vitro and in vivo. Carefully selected probiotic Lactobacillus strains could therefore play an important role in the treatment of H. pylori infection and eradication. However, the underlying mechanism for...

Three new serotypes of Rhodococcus equi in Prescott's serotyping system - Short communication.

PMID: 26551416
Acta Vet Hung. 2015 Sep;63(3):265-70. doi: 10.1556/004.2015.024.

Three new serotypes were found among Rhodococcus equi strains, which could not be assigned into any of the seven serotypes of Prescott's system. Fortythree R. equi strains out of 44 previously nontypable ones isolated in Hungary could be allocated...

Role of Hydrogen and Oxygen Activation over Pt and Pd-Doped Composites for Catalytic Hydrogen Combustion.

ACS applied materials & interfaces

Singh SA, Vishwanath K, Madras G.
PMID: 27712051
ACS Appl Mater Interfaces. 2017 Jun 14;9(23):19380-19388. doi: 10.1021/acsami.6b08019. Epub 2016 Oct 20.

Removal of excess amount of hydrogen in a catalytic route is a safety measure to be implemented in fuel cell technologies and in nuclear power plants. Hydrogen and oxygen activation are crucial steps for hydrogen combustion that can be...

Graphene-oxide-supported ultrathin Au nanowires: efficient electrocatalysts for borohydride oxidation.

Chemical communications (Cambridge, England)

Leelavathi A, Ahmad R, Singh AK, Madras G, Ravishankar N.
PMID: 26439584
Chem Commun (Camb). 2015 Dec 07;51(94):16856-9. doi: 10.1039/c5cc06705g.

We report stable ultrathin Au nanowires supported on reduced graphene oxide with outstanding electrocatalytic activity for borohydride oxidation. Electrochemical impedance spectroscopy measurements showed abnormal inductive behavior, indicative of surface reactivation. DFT calculations indicate that the origin of the high...

Million-Fold Decrease in Polymer Moisture Permeability by a Graphene Monolayer.

ACS nano

Seethamraju S, Kumar S, B KB, Madras G, Raghavan S, Ramamurthy PC.
PMID: 27314156
ACS Nano. 2016 Jul 26;10(7):6501-9. doi: 10.1021/acsnano.6b02588. Epub 2016 Jul 13.

Flexible, transparent, and moisture-impermeable materials are critical for packaging applications in electronic, food, and pharmaceutical industries. Here, we report that a single graphene layer embedded in a flexible polymer reduces its water vapor transmission rate (WVTR) by up to...

Brain Iron and Zinc Contents of German Patients with Alzheimer Disease.

Journal of Alzheimer's disease : JAD

Andrási E, Farkas E, Gawlik D, Rösick U, Brätter P.
PMID: 12214107
J Alzheimers Dis. 2000 Mar;2(1):17-26. doi: 10.3233/jad-2000-2103.

Our first project aimed to determine the average values of Fe and Zn in normal German human brain (5 individuals, 10 brain parts). Determinations were carried out by instrumental neutron activation analysis in Berlin. Quality control measurements were performed...

Dihydroxamate based siderophore model, piperazine-1,4-bis-(N-methyl-acetohydroxamic acid (PIPDMAHA), as a chelating agent of molybdenum(VI).

Talanta

Farkas E, Csóka H, Gama S, Santos MA.
PMID: 18968698
Talanta. 2002 Jul 03;57(5):935-43. doi: 10.1016/s0039-9140(02)00135-2.

Equilibrium studies based on pH-potentiometric and spectrophotometric measurements as well as some theoretical simulations are reported for the complexes of Mo(VI) with a dihydroxamate type siderophore analogue, the piperazine-1,4-bis-(N-methyl-acetohydroxamic acid) (PIPDMAHA). It has been found that the complexation process...

Al, Zn, Cu, Mn and Fe levels in brain in Alzheimer's disease.

Archives of gerontology and geriatrics

Andrási E, Farkas E, Scheibler H, Réffy A, Bezúr L.
PMID: 15374228
Arch Gerontol Geriatr. 1995 Jul-Aug;21(1):89-97. doi: 10.1016/0167-4943(95)00643-y.

The aim of our experiments was to investigate the possible element concentration changes in Alzheimer's disease. Our project incorporated the determination of the regional distribution of elements in normal human brain, too. Five elements (Al, Zn, Cu, Mn and...

Conjugated polymers for photocatalysis.

Population balance equations (PBEs) for reversible aggregation-fragmentation processes are important to particle agglomeration and dissolution, polymerization and degradation, liquid droplet coalescence and breakup, and floc coagulation and disintegration. Moment solutions provide convenient solutions to the PBEs, including steady state...
