Abstract:

The g-proteobacterium Shewanella oneidensis MR-1 reduces a wide range of terminal electron acceptors, including solid Fe(III) oxides. Pathways for Fe(III) oxide reduction by S. oneidensis include non-reductive (organic ligand-promoted) solubilization reactions, and either direct enzymatic, or indirect electron shuttling pathways. Results of the present study expand the spectrum of electron acceptors reduced by S. oneidensis to include the naturally occurring disulfide compounds cystine, oxidized glutathione, dithiodiglycolate, dithoidiproponiate and cystamine. Subsequent electron shuttling

Abstract:

Dissimilatory sulfate reduction plays a significant role in shaping the sulfur isotope composition of sedimentary sulfides. These, in turn, record the evolution of Earth's surface redox state. The fractionation produced by this microbial metabolism is controlled by the flux of sulfur through the respiratory reaction network and the isotopic effect associated with each component reaction. Although the net isotope fractionations of this metabolism have been well studied, unraveling the isotopic influence of each component of its pathway is still a challenge.

Abstract:

Ageing and diabetes are two major healthcare concerns that used to be regarded as problems of the Western world but are now of increasing concern in developing nations. Treating elderly patients with diabetes poses issues for clinicians due to often complex, preexisting drug regimes. Research targeted at the development of novel drugs that have multiple effects on diabetes could go some way towards reducing polypharmacy in these patients. Here I present evidence that the oral Jak1/3 inhibitor, baricitinib, has effects on multiple aspects of diabetes. Baricitinib has been suggested to be a stro

Abstract:

Humankind's tremendous industrial and technological progress over the last two centuries has been driven by the natural abundance and availability of fossil fuels. As those reserves deplete, the prudent course of action would be to develop other readily available fuel sources. Some research efforts using biomolecules involve the hydrogenases and nitrogenases with the goal of evolving dihydrogen. At the nitrogenase active site, the iron-molybdenum cofactor (FeMo-co) catalyzes the reduction of dinitrogen and protons to form ammonia and dihydrogen. Toward the goal of producing dihydrogen pas

Abstract:

Mercury (Hg) is a global pollutant and potent neurotoxin that bioaccumulates in aquatic and terrestrial food webs as monomethylmercury (MeHg). Anaerobic microbes are largely responsible for MeHg production, which depends on the bioavailability of inorganic Hg substrates to methylators. Hg redox cycling pathways such as Hg reduction play a key role in determining Hg’s availability in the environment. Although abiotic photochemical Hg reduction typically dominates in oxic surface environments, Hg reduction pathways mediated by photosynthetic and anaerobic microbes are thought to play an importan

Abstract:

Due to the high dimensionality of most biological data, it is a difficult task to directly analyze, model and visualize the data to gain biological insight. Thus, dimensionality reduction becomes an imperative pre-processing step in analyzing and visualizing high-dimensional biological data. Two major approaches to dimensionality reduction in genomic analysis and biomarker identification studies are: Feature extraction, creating new features by combining existing ones based on a mapping technique; and feature selection, choosing an optimal subset of all features based on an objective function.

From a regulatory point of view, the capability to simulate the kinetics of these reductive transformation reactions coupled with other attenuation processes in the subsurface (e.g., sorption, advection, and dispersion) is required for site-specific solute transport models.

Abstract:

La transition énergétique est un enjeu majeur actuel et des années à venir. Parmi les défis qu’elle va soulever figure la limitation des impacts environnementaux de la production d’électricité. Pour cela, des outils d’aide à la décision, simples d’utilisation et suffisamment précis, considérant les aspects environnementaux et permettant d’optimiser les choix énergétiques futurs, doivent être mis en place. L’analyse environnementale d’une filière de conversion d’énergie est un sujet complexe. Elle comporte en effet deux niveaux. Le niveau « filière », caractérise le profil global d’impacts envi

Durante o seu ciclo replicativo, o HIV promove diversas alterações na fisiologia da célula hospedeira a fim de promover sua sobrevivência e potencializar a replicação. A rápida progressão da infecção pelo HIV-1 em humanos e em modelos animais está intimamente ligada à função da proteína acessória Nef. Dentre as diversas ações de Nef está a regula

However, the lack of band gap limits applicability in graphene device. Graphene oxide (GO) engineers band gap through introduction of sp3 bonding. Tuning the electric properties by controlling the degree of oxidation and reduction is one of the most popular method. So far, there are many methods evolving to reduce GO, e.g., chemical, thermal, and

Abstract:

The high demand for copper is coinciding with a sharp decline in the grade of copper reserves, and as a result, copper scarcities are expected to arise in the coming decades. In this work, a transformative hydrometallurgical process is being developed to lower the costs of copper production and thereby sustain the use of copper throughout the global transition to renewable energy technologies. The focal point of the hydrometallurgical process is the reductive treatment of chalcopyrite, which is in contrast to the oxidative treatment more commonly pursued in the literature. Chalcopyrite may be
