Metabological engineering of Pichia Pastoris for extracellular thermostable glucose isomerase production
Ata, Özge; Çalık, Pınar; Özdamar, Tunçer H.; Department of Biotechnology (2012)
The aim of this study is to develop a metabolically engineered P. pastoris strain for production of an active extracellular thermostable glucose isomerase (GI) enzyme by using genetic engineering techniques. For this purpose, research program was performed in two sub-programs. In the first sub-program, xylA gene from Thermus thermophilus was amplified and inserted into pPICZα-A expression vector. Thereafter, this pPICZα-A::xylA vector was cloned into AOX1 locus in P. pastoris genome and expressed under alco...

Comparative data on the mechanical properties of epidural catheters used clinically are not available. We performed a controlled laboratory investigation to assess the mechanical performance of three different intact or traumatized catheter types (Polyurethane, clear nylon, and radiopaque nylon catheters, designed for 18-gauge Tuohy needles). We studied a control (intact) and two trauma groups (needle bevel and surgical blade). Catheters were loaded to their breaking points by using a Lloyd LS500 material t...

Electrospinning of cyclodextrin functionalized poly(methyl methacrylate) (PMMA) nanofibers
Uyar, Tamer; Balan, Abidin; Toppare, Levent Kamil; Besenbacher, Flemming (Elsevier BV, 2009-01-16)
Cyclodextrin functionalized PMMA nanofibers (PMMA/CD) were successfully produced by electrospinning technique with the goal to develop functional nanowebs. Bead-free uniform electrospun PMMA/CD nanofibers were obtained from a homogeneous solution of CDs and PMMA in dimethylformamide (DMF) using three different types of CDs, alpha-CD, beta-CD and gamma-CD. The electrospinning conditions were optimized in order to form bead-free PMMA/CD nanofibers by varying the concentrations of PMMA and CDs in the solutions...
