The invention relates to a mutant strain of bacteria, which either lacks or contains mutant genes for several key metabolic enzymes, and which produces high amounts of succinic acid under anaerobic conditions.


The present invention provides an oligonucleotide composition including a blocker and a first primer oligonucleotide. The blocker oligonucleotide includes a first sequence having a target-neutral subsequence and a blocker variable subsequence. The non-target specific subsequence is flanked on its 3 and 5 ends by the target-neutral subsequence and is continuous with the target-neutral subsequence. The first primer oligonucleotide is sufficient to induce enzymatic extension; herein the first primer oligonucleotide includes a second sequence. The second sequence overlaps with the 5 end of the target-neutral subsequence by at least 5 nucleotides; herein the second sequence includes an overlapping subsequence and a non-overlapping subsequence. The second sequence does not include the non-target specific subsequence.

One aspect of the invention provides an artificial, flexible valve including: a stent defining a wall and a plurality of leaflets extending from the wall of the stent. The plurality of leaflets form a plurality of coaptation regions between two adjacent leaflets. The coaptation regions include extensions along a z-axis and adapted and are configured to form a releasable, but substantially complete seal when the leaflets are in a closed position. Another aspect of the invention provides an artificial, flexible valve including: a stent defining a wall and a plurality of leaflets extending from the wall of the stent. Each of the plurality of leaflets terminates in a commissure line. The commissure lines deviate from a hyperbola formed in the x-y plane by at least one deviation selected from the group consisting of: a deviation in the z-direction and one or more curves relative to the hyperbola.

Embodiments of the present disclosure pertain to scalable methods of producing carbon quantum dots with desired bandgaps by the following steps: exposing a carbon source to an oxidant at a reaction temperature, where the exposing results in the formation of the carbon quantum dots; and selecting a desired size of the formed carbon quantum dots. In some embodiments, the selecting occurs by at least one of separating the desired size of the formed carbon quantum dots from other formed carbon quantum dots; selecting the reaction temperature that produces the desired size of the formed carbon quantum dots; and combinations of such steps. The desired size of carbon quantum dots can include a size range. The methods of the present disclosure can also include a step of purifying the formed carbon quantum dots prior to selecting a desired size.

A hearing device may provide hearing-to-touch sensory substitution as a therapeutic approach to deafness. Through use of signal processing on received signals, the hearing device may provide better accuracy with the hearing-to-touch sensory substitution by extending beyond the simple filtering of an incoming audio stream as found in previous tactile hearing aids. The signal processing may include low bitrate audio compression algorithms, such as linear predictive coding, mathematical transforms, such as Fourier transforms, and/or wavelet algorithms. The processed signals may activate tactile interface devices that provide touch sensation to a user. For example, the tactile interface devices may be vibrating devices attached to a vest, which is worn by the user. The vest may also provide other types of information to the user.

High-transition temperature (high-Tc) superconductivity in the iron pnictides or chalcogenides emerges from the suppression of the static antiferromagnetic order in their parent compounds, similar to copper oxide superconductors. This raises a fundamental question concerning the role of magnetism in the superconductivity of these materials. Neutron scattering, a powerful probe to study the magnetic order and spin dynamics, plays an essential role in determining the relationship between magnetism and superconductivity in high-Tc superconductors. The rapid development of modern neutron time-of-flight spectrometers allows a direct determination of the spin dynamical properties of iron-based superconductors throughout the entire Brillouin zone. In this paper, an overview is presented of the neutron scattering results on iron-based superconductors, focusing on the evolution of spin-excitation spectra as a function of electron and hole doping and isoelectronic substitution. Spin dynamical properties of iron-based superconductors are compared with those of copper oxide and heavy fermion superconductors and the common features of spin excitations in these three families of unconventional superconductors and their relationship with superconductivity are discussed. © 2015 American Physical Society.

Chemists have long been fascinated by metalloenzymes and their chemistry. Because enzymes are essential for biological processes and to life itself, they present a key to understanding the world around us. At the same time, if chemists could harness the reactivity and selectivity of enzymes in designed transition-metal catalysts, we would have access to a powerful practical advance in chemistry. But the design of enzyme-like catalysts from scratch presents enormous challenges. Simplified, designed systems often don't provide the opportunity to mimic the complex features of enzymes such as selectivity in polyfunctional environments and access to reactive intermediates incompatible with bulk aqueous solution.Extensive efforts by numerous groups have led to remarkable designed metalloproteins that contain complex folds, including well-defined secondary and tertiary structure surrounding complex polymetallic centers. These structural achievements, however, have not yet led to general approaches to useful catalysts; continued efforts and new insights are needed. Our efforts have combined the attributes of enzymatic and traditional catalysis, bringing the benefits of polypeptide ligands to bear on completely nonbiological transition-metal centers. With a focus on designing useful catalytic activity, we have examined rhodium(II) carboxylates, bound to peptide chains through carboxylate side chains. Among other advantages, these complexes are stable and catalytically active in water.Our efforts have centered on two main interests: (1) understanding how Nature's ligand of choice, polypeptides, can be used to control the chemistry of nonbiological metal centers, and (2) mimicking metalloenzyme characteristics in designed, nonbiological catalysts. This Account conveys our motivation and goals for these studies, outlines progress to date, and discusses the future of enzyme-like catalyst design.In particular, these studies have resulted in on-bead, high-throughput screens for asymmetric metallopeptide catalysts. In addition, peptide-based molecular recognition strategies have facilitated the site-specific modification of protein substrates. Molecular recognition enables site-specific, proximity-driven modification of a broad range of amino acids, and the concepts outlined here are compatible with natural protein substrates and with complex, cell-like environments. We have also explored rhodium metallopeptides as hybrid organic-inorganic inhibitor molecules that block protein-protein interactions. © 2012 American Chemical Society.
