The addition of NT-3 (neurotrophin 3) or NT-4 to injured nerves improves their regeneration potential and may aid axon guidance. It is not well defined whether NTs (neurotrophins) influence other elements, such as the cell-adhesion molecules, which promote nerve guidance and regeneration. Using poly3-hydroxybutyrate conduits, we applied either NT-3 or NT-4 to axotomized rat sciatic nerves and m...

in order to reduce the costs associated with poly-β-hydroxybutyrate production, growth and poly-β-hydroxybutyrate production of ralstonia eutropha were studied in batch culture on different carbon sources. experiments were designed and conducted to not only lower the cost of poly-β-hydroxybutyrate production by using inexpensive substrates, but also to increase poly-β-hydroxybutyrate production...

Ultrathin ferroelectric polyvinylidene fluoride (70%)-tetrafluoroethylene (30%) copolymer film is inserted between the poly3(hexylthiophene) (P3HT) donor and [6,6]-phenyl-C61-butyric acid methylester (PCBM) acceptor layers as the dipole layer to tune the relative energy levels, which can potentially maximize the open circuit voltage of bilayer organic solar cells. In this work, the power conver...

Here we report the modification of an amphiphilic antibacterial polynorbornene, Poly3, via incorporation of hydrophilic, biocompatible groups. The sugar, zwitterionic, and polyethylene glycol based moieties were incorporated in varying ratios by copolymerization and postpolymerization techniques. Well-defined copolymers with molecular weights of 3 kDa and narrow polydispersity indices ranging f...

conclusions the results suggest that b. coagulans is a good candidate for the fermentative production of phb. background biodegradable polyesters are candidates for the development of environmental friendly plastics. poly-β-hydroxybutyrate (phb) is a type of polyester from the hydroxyalkanoates family, synthesized by bacteria as an intracellular material and accumulated as granules in the cytop...

Topology control is a technique used in wireless sensor networks to maximize energy efficiency and network lifetime. In previous literature, many tree based techniques have been proposed to save energy and increase the network lifetime. In tree based algorithms, the most promising solution is the formation of a network backbone, which serves on behalf of rest of the nodes in the network and the...

Background: Glycation is the non-enzymatic reaction between the carbonyl groups in sugar and free amino groups in proteins. this reaction leads to changes in structure and functions of proteins. Advanced glycation end products (AGEs) is the final stage in this process, which is highly oxidizing and destructive nature, causing many diabetic complications. Methods: In the present investigation, ...

Exogenous 3-hydroxybutyrate can be utilized by a variety of soil bacteria as a carbon and energy source. However, the membrane transporter responsible for 3-hydroxybutyrate uptake remains unidentified. The Bacillus subtilis strain 168 gene yxjC (herein renamed hbuT) encodes a putative gluconate transporter GntT-type membrane transporter with a previously unknown function. hbuT is organized with...

A recombinant Escherichia coli strain has been developed that produces poly(3-hydroxybutyrate-co-4-hydroxybutyrate) when grown in complex medium containing glucose. This has been accomplished by introducing into E. coli DH5 alpha separate plasmids harboring the polyhydroxyalkanoate (PHA) biosynthesis genes from Ralstonia eutropha (formerly named Alcaligenes eutrophus) and the succinate degradat...
