Candida species are a major cause of catheter infections. Using a central venous catheter Candida albicans biofilm model, we demonstrated that chitosan, a polymer isolated from crustacean exoskeletons, inhibits candidal biofilm formation in vivo. Furthermore, chitosan statistically significantly decreased both the metabolic activity of the biofilms and the cell viability of C. albicans and Candida parapsilosis biofilms in vitro. In addition, confocal and scanning electron microscopic examination demonstrated that chitosan penetrates candidal biofilms and damages fungal cells. Importantly, the concentrations of chitosan that were used to evaluate fungal biofilm susceptibility were not toxic to human endothelial cells. Chitosan should be considered for the prevention or treatment of fungal biofilms on central venous catheters and perhaps other medical devices. © 2010 by the Infectious Diseases Society of America.

Entamoeba histolytica infects 50 million people per year, causing 100,000 deaths worldwide. The primary treatment for amoebiasis is metronidazole. However, increased pathogen resistance combined with the drug's toxic side effects encourages a search for alternative therapeutic agents. Secondary metabolites from marine bacteria are a promising resource for antiprotozoan drug discovery. In this study, extracts from a collection of marine-derived actinomycetes were screened for antiamoebic properties, and the activities of antibiotics echinomycin A and tirandamycin A are shown. Both antibiotics inhibited the in vitro growth of a E. histolytica laboratory strain (HM-1:IMSS) and a clinical isolate (Colombia, Col) at 30- to 60-μM concentrations. EIC50 (estimated inhibitory concentration) values were comparable for both antibiotics (44.3-46.3 μM) against the E. histolytica clinical isolate. © Springer-Verlag 2012.

Knowledge, belief, and evidence are fundamental notions which appear in a wide range of areas. Over the last decade epistemic reasoning with justifications has broadened even more the scope of applications of epistemic logic as agents gained the ability to not only reason about epistemic states of knowledge and belief of agents, but also to track their justifications and to sort those which are pertinent to given facts and sufficient for epistemic conclusions. This paper extends realization algorithm for S4-to-LP case to S4Jn-to-S4nLP case. It converts cut-free derivations in S4Jn into derivations in the corresponding Justification Logic S4nLP where witnesses of knowledge, the justification terms, are recovered for all instances of justified common knowledge. The algorithm was implemented in the MetaPRL framework and was tested on several well-known epistemic puzzles, such as Muddy Children, Surprise Examination Paradox, etc. © 2015 The Author.

Common Knowledge C is a standard tool in epistemic logics. Generic Common Knowledge J is an alternative which has desirable logical behavior such as cut-elmination and which can be used in place of C in the analysis of many games and epistemic senarios. In order to compare their deductive strengths directly we define the multi-agent logic S4 CJ n built on a language with both C and J operators in addition to agents’ Kis so that any finite prefix of modal operators is acceptable. We prove S4 CJ n is complete, decidable, and that Jφ→Cφ though not Cφ→Jφ. Additional epistemic scenarios may be investigated which take advantage of this dual layer of common knowledge agents. © Springer International Publishing Switzerland 2016.

With an aim to increase the energy density compared to current Li-ion batteries, there is immense interest in rechargeable batteries with multivalent cations, such as Mg2+ and Zn2+, as they could provide higher charge storage capacity. α-MnO2 has been investigated as a cathode for Zn-ion batteries, but other structures could be explored. Accordingly, this study investigates the chemical extraction of Zn from the spinel compositions ZnMn2-xNixO4 (x = 0, 0.5, and 1) using H2SO4 and NO2BF4. Acid treatment is able to extract Zn from the structure through a Mn3+ disproportionation reaction that is dependent on the Mn3+ content. Zn extraction decreases with increasing Ni content due to the decrease in Mn3+ content; in fact, ZnMnNiO4 does not lose any Zn upon acid treatment because all of the Mn ions are in the 4+ state. Treatment with NO2BF4, however, is unable to extract any Zn from the samples, unlike in the analogous LiMn2O4 spinel. This is believed to be due to the high electrostatic repulsion that Zn2+ ions would feel from other Zn2+ ions in neighboring tetrahedral sites as they have to diffuse through the unoccupied octahedral sites in the spinel lattice, and Zn2+ does not prefer octahedral sites. Because NO2BF4 more closely approximates the extraction mechanism experienced in a Zn-ion cell, it appears that the ideal spinel structure is not suitable as a Zn-ion battery cathode unless synthesis conditions or additional treatments were used to create vacancies in the structure that allows for easier Zn-ion diffusion without much electrostatic repulsion. © The Royal Society of Chemistry.

This study analyzes data collected from Italian language online classes during the course of four consecutive semesters at Bronx Community College in order to measure the impact that distance learning has on students’ retention and success rates in elementary courses. The results reveal that reconfiguring the online meetings to a lower percentage and implementing social pedagogies reduce course abandonment and favor the creation of strong learning communities. Furthermore, the data relative to the grade distribution shows no substantial difference between online courses and face-to-face instruction. © 2015, Italian e-Learning Association.

For permission for commercial reuse, please email: products formed by the chemical extraction of lithium from LiMn2-xMxO4 (M = Cr, Fe, Co, and Ni) with aqueous sulfuric acid have been structurally and chemically characterized. The amount of lithium extracted is found to be proportional to the initial Mn3+ content, confirming the reaction mechanism, LiMn3+Mn4+O4 → 0.75 Mn2O4 + 0.5 Li2O + 0.5 MnO. Thus, no lithium is extracted from LiMn1.5 4+Ni0.5 2+O4 as there is no Mn3+, while complete delithiation occurs in LiMn3+Mn4+O4 to give Mn2O4. The amount of lithium extracted from the other samples is in good agreement with that calculated from the Mn3+ content. The XRD data confirm the maintenance of the spinel structure for the delithiated samples, while the redox titration confirmed the maintenance of oxygen content at 4.0, indicating that no protons were inserted into the lattice during delithiation. The findings could provide more insight on the problem of metal dissolution from cathode materials in lithium-ion batteries. © The Author(s) 2014. Published by ECS.
