Abstract: Provided are methods and compositions for high yields while using reduced enzyme loads in saccharification and fermentation processes. These methods increase the efficiency of enzymes and result in improved yields and composition of saccharification and fermentation end products.

Abstract: Composite probes for super resolution optical techniques using super resolution via transiently activated quenchers (STAQ) include a donor moiety and an acceptor moiety joined by a linker, wherein the acceptor moiety, when excited by incident radiation, is excited to a state which, for example, absorbs in the donor emission region, such that the acceptor moiety in its excited state quenches at least a portion of the donor moiety emission. Other transiently activated quenching mechanisms and moieties could accomplish the same task by reducing donor population. Also disclosed are methods for irradiating a selected region of a target material including the composite probe, wherein the composite probe enables improved resolution by point spread function modification and/or nanoscale chemical reactions.

Abstract: A process for mixing seawater, feather additive, and one or more algae to prepare a nutrient-rich feedstock for cultivating, growing, and harvesting algae. The harvested algae are processed to produce biofuel, oil, nutrient supplements, and polymers used for cosmetics.

Abstract: Human PIK4CA genes are identified as modulators of the RAC pathway, and thus are therapeutic targets for disorders associated with defective RAC function. Methods for identifying modulators of RAC, comprising screening for agents that modulate the activity of PIK4CA are provided.

Abstract: The present invention corresponds to a commercial production process of ferric sulfate whose plant can be installed scaled to the requirements of the process of application of the bio-produced ferric solution based on fayalite slag generated in copper smelting plants. No previous process has established as its method of industrial application the use of these smelter slags in the bio-production of ferric sulfate solutions at concentrations above 20 g/L, including a stage of acid-slag leaching in dynamic heaps with control of generated silica and subsequent precipitation of colloidal silica and other impurities in a stirred reactor in the invented process. The ferrous solution free of colloidal silica and other impurities is subjected to a process of bio-oxidization of the clean ferrous solution by microorganisms adapted to these metallurgical solutions.

Abstract: The present invention relates to a method of detecting the presence of cancer by measuring the level of enzyme activity and autoantibodies in the blood of an individual. In particular the present invention relates to methods for measurement of activated cAMP-dependent protein kinase A (PKA) activity and antibodies to PKA, a kit for activated PKA activity measurement, and the use of the measured levels of these analytes for determining the presence of cancer.

Abstract: Tube and float systems and methods for isolating, enumerating, and harvesting target materials of a suspension are described. In one aspect, a tube and float system includes a filter embedded in a tube cap. The filter enables the passage of fluids but prevents the passage of the target materials. The tube and float system can be used to isolate and enumerate the target materials by centrifuging the tube and float system with the suspension to trap the target materials between the float and inner wall of the tube. Fluids above and below the float are poured off and a second fluid can be introduced to the tube to re-suspend the trapped target material. The second fluid can be poured through the filter in the cap to trap the target material against the filter. The target material can be enumerated and analyzed.

Abstract: The formulations, systems, and methods disclosed herein permit automated preparation of specimens (e.g., biological specimens) for examination. The formulations can include a cytological fixative solution including Azure B, a surfactant, methanol, and ethylene glycol. The disclosed formulations, systems, and methods provide fast, efficient, and highly uniform specimen processing using minimal quantities of fluids. The methods include at least a fixing phase for fixing a specimen to a substrate such as a microscope slide, a staining phase for staining the specimen, and a rinsing phase for rinsing the specimen. One or more of the fixing, staining, and rinsing phases include one or more agitation phases for distributing reagents evenly and uniformly across the specimen. The systems can be implemented as a standalone device or as a component in a larger system for preparing and examining specimens.
