Abstract: The present disclosure related to isolated laminin-521, methods for making recombinant laminin-521, host cells that express recombinant laminin-521, and compositions containing laminin-521. Laminin-521 can maintain stem cells in vitro pluripotency, enable self-renewal, and enable single cell survival of human embryonic stem cells. When pluripotent human embryonic stem cells are cultured on plates coated with recombinant laminin-521 (laminin-11), in the absence of differentiation inhibitors or feeder cells, the embryonic stem cells proliferate and maintain their pluripotency. It has also been discovered that human recombinant laminin-521 (laminin-11) provides single cell survival of stem cells after complete dissociation into a single cell suspension. Useful cell culture mediums containing at most 3.9 ng/ml of beta fibroblast growth factor (bFGF) are also described herein.
Abstract: The disclosure describes fungal organisms and preparations useful for inhibiting infection by Xylella sp. and in the treatment of Pierce's Disease.

Abstract: A technique is provided to visualize microtubules in live cells that does not require genetic manipulation or microinjection. Moreover, this method also avoids perturbation of the endogenous microtubule network that occurs with taxol treatment. This technique exploits tyrosination and detyrosination of tubulin, a posttranslational modification cycle specific to the C-terminus of ?-tubulin. Specifically, cells are grown in medium supplemented with a tyrosine derivative possessing a reactive functional group. The cellular enzyme tubulin tyrosine ligase attaches the unnatural amino acid to a single site on tubulin. Addition of fresh medium containing a suitably derivatized fluorophore then yields fluorescent tubulin, which incorporate into cellular microtubules. Importantly, the tubulin labeling approach demonstrated here does not detrimentally affect microtubule network or cell morphology. Thus we present a simple, robust labeling technique that allows microscopic analysis of microtubules in live cells.

Abstract: This invention provided a preparation method of the composite which was immobilized Paracoccus denitrificans on modified graphene oxide and its application. The composite was obtained by following the steps below: 1) Synthesis of graphene oxide; 2) Synthesis of modified graphene oxide; 3) Acclimatization and immobilization of Paracoccus denitrificans. In this invention, the raw materials were low-cost and easily obtained used in the preparation process; easy operation, convenient, and no expensive instruments during the whole process; this invention of the composite could remove DMF from wastewater completely, and with the advantages of high efficiency, good recycle performance, economical, environmentally friendly, better feasibility.
Abstract: Provided herein is a method comprising one or more of the following steps: (a) lysing cells of a biological sample and contacting the biological sample with an amount of ionic liquid sufficient to denature intracellular metabolic enzymes in the biological sample to produce a contacted cellular sample; (b) mixing the contacted cellular sample with an organic solvent to produce an ionic liquid-organic solvent composition; (c) mixing the contacted cellular sample with the organic solvent to produce a dispersed microdroplet ionic liquid-organic solvent composition; (d) contacting the ionic liquid-organic solvent composition with an ion exchange composition to produce a second ionic liquid-organic solvent composition; (d) separating the ionic liquid from the organic solvent; and (e) extracting metabolites from the ionic liquid. Kits and systems for practicing the subject methods are also provided.

Abstract: The present invention relates to a method for evaluating the integrity of the cell wall of the bacteria present in a culture in the presence of an antibiotic acting on the bacterial cell wall which, from a practical point of view, allows quickly determining if a bacterium is sensitive or resistant to an antibiotic acting on the bacterial cell wall. Likewise, the present invention also relates to a lysis solution applicable in the preceding method, specifically affecting bacteria having the cell wall damaged by the action of an antibiotic acting on the bacterial cell wall, which allows distinguishing bacteria sensitive to said antibiotic from those resistant to said antibiotic.

Abstract: 2,5-Bis(benzoxazol-2?-yl)benzene-1,4-diol derivatives (Zinhbo derivatives) are used to detect zinc ions and have particular application in vivo and in vitro. Zinhbo derivatives upon excitation give a florescence response emission that can be used to determine the presence of zinc cation in solution. Zinhbo derivatives complexed with zinc cations upon excitation can produce a florescence response emission in the visible and near infrared range. Zinhbo derivatives complexed with zinc cations exhibit a large stoke shift between the excitation and emission wavelengths.
Abstract: The present invention provides a simpler and more energy efficient process for the preparation of fatty acid methyl ester (biodiesel) from sun dried whole seed capsules of Jatropha curcas integrated with value addition of seed shells, deoiled cake and crude glycerol co-product stream. More specifically, the invention relates to a method of dispensing with the need for excess methanol recovery through distillation, cost-effective resin treatment for the refining of methyl ester and utilization of co-streams for preparation of high density energy briquettes and Polyhydroxyalkanoate biodegradable polymer in efficient and cost-effective manner.

Abstract: The present invention includes new hybrid hydrogel scaffolds comprised of a polyoxyethylene-polyoxypropylene (block) copolymer (a “poloxamer”) and a self-assembling peptide, which maintain the mechanical and bioactive properties of its individual constituents (as compared to when the individual constituents are scaffolds or hydrogels by themselves). The hydrogels of the invention can include a combination of materials from different origins or with different properties that provides a hybrid material that meets the multiple needs of a scaffold for tissue engineering.
