The paper concerns the thermoelastic problems in a thermosensitive elliptical plate subjected to the activity of a heat source which changes its place on the plate surface with time. The solution of conductivity equation and the corresponding initial and boundary conditions is obtained by employing a new integral transform technique. In addition, the intensities of bending moments, resultant fo...

A novel nanocomposite hydrogel with controllable multiple thermosensitivity has been synthesized by introducing poly(ethylene glycol) (PEG) into clay/poly(N-isopropylacrylamide) (PNIPAAm) nanocomposite hydrogel, which exhibits double thermosensitive phase transition: a UCST and a LCST spontaneously.

Low polydispersity poly(N-isopropylacrylamide) with a biotin end-group was obtained in one step from a biotinylated initiator for atom transfer radical polymerization and interacted with streptavidin to generate the thermosensitive polymer-protein conjugate.

The ability to efficiently and reliably transfer genetic circuits between the key synthetic biology chassis, such as Escherichia coli and Bacillus subtilis, constitutes one of the major hurdles of the rational genome engineering. Using lambda Red recombineering we integrated the thermosensitive lambda repressor and the lysis genes of several bacteriophages into the E. coli chromosome. The lysis...

In the bivoltine strain of the silkworm, Bombyx mori, embryonic diapause is induced transgenerationally as a maternal effect. Progeny diapause is determined by the environmental temperature during embryonic development of the mother; however, its molecular mechanisms are largely unknown. Here, we show that the Bombyx TRPA1 ortholog (BmTrpA1) acts as a thermosensitive transient receptor potentia...

After nitrosoguanidine mutagenesis, a mutant Escherichia coli strain harboring the Clo DF13::Tn901 plasmid pJN03 was isolated that is thermosensitive (Ts) for growth at 43 degrees C. The mutation responsible for this thermosensitive phenotype resides on the pJN03 plasmid genome. Cells harboring the pJN03 cop-1(Ts) plasmid mutant showed a large increase in plasmid copy number at 43 degrees C acc...

Pluronic F127 (PF127) is a copolymer which forms thermosensitive hydrogels. Hyaluronic acid (HA) was grafted to PF127 to form a new hydrogel matrix (HP) for delivery of cisplatin and carboplatin. The physicochemical properties and drug delivery of the graft were examined in this study. HP system (20% HP copolymer in water) exhibited a similar sol-gel transition temperature (28.3 degrees C) as P...

Chemical cross-linking of gelatin is achieved using a thermosensitive reactive copolymer based on N-isopropylacrylamide (NIPAM). The copolymer bears 5 mol % acrylic acid units which form amide bonds with the amino groups of gelatin in the presence of a water-soluble carbodiimide. The cross-linking reaction occurs only below the LCST congruent with 34 degrees C (lower critical solution temperatu...

Mutants of Penicillium janthinellum NCIM 1171 were evaluated for cellulase production using both submerged fermentation (SmF) and solid state fermentation (SSF). Mutant EU2D-21 gave highest yields of cellulases in both SmF and SSF. Hydrolysis of Avicel and cellulose were compared using SmF and SSF derived enzyme preparations obtained from EU2D-21. Surprisingly, the use of SSF derived preparatio...
