The progressive rise in energy crisis followed by green house gas (GHG) emissions is serving as the driving force for bioethanol production from renewable resources. Current bioethanol research focuses on lignocellulosic feedstocks as these are abundantly available, renewable, sustainable and exhibit no competition between the crops for food and fuel. However, the technologies in use have some ...

Protein S (PS) enhances the inhibition of factor Xa (FXa) by tissue factor pathway inhibitor(TFPI) in the presence of Ca2 and phospholipids. Altered forms of recombinant TFPIwere used to determine the structures within TFPIthat may be involved in this PS-dependent effect. Wild-type TFPI(TFPIWT), TFPIlacking the K3 domain (TFPIK3), and TFPIcontaining a single amino acid change at the putative P1...

Let X be a K3 surface which is intersection of three (a net P) of quadrics in P. The curve of degenerate quadrics has degree 6 and defines a double covering of P K3 surface Y ramified in this curve. This is the classical example of a correspondence between K3 surfaces which is related with moduli of vector bundles on K3 studied by Mukai. When general (for fixed Picard lattices) X and Y are isom...

INTRODUCTION Apical transportation changes the physical shape and physiologic environment of the root canal terminus. The aim of the present experimental study was to determine the extent of apical transportation after instrumentation with hand K-Flexofile and K3 rotary instruments by means of cone-beam computed tomography (CBCT). METHODS AND MATERIALS Forty mesiobuccal root canals of maxilla...

In 11 normal volunteers and six patients with Parkinson's disease, we compared six different analyses of dopaminergic function with L-3,4-dihydroxy-6-[18F]fluorophenylalanine (FDOPA) and positron emission tomography (PET). The caudate nucleus, putamen, and several reference regions were identified in PET images, using magnetic resonance imaging (MRI). The six analyses included two direct determ...

Recent evidence suggest that a β-glucan derived from mushroom Schizophyllan(SPG) complexed with a humanized TLR9 agonistic CpG DNA, K3 (K3-SPG) is a promising vaccine adjuvant that induces robust CD8 T cell responses to co-administered antigen. However, it has not been investigated whether K3-SPG alone can act as an anti-cancer immunotherapeutic agent or not. Here, we demonstrate that intraveno...

The aim of this study was to evaluate the percentage of reticulated platelets in healthy dogs with breed-related thrombocytopenia. Seventy two dogs, clinically healthy, were enrolled in the study. Blood was collected from the patients and anticoagulated with tripotassium ethylenediaminetetraacetic acid (K3-EDTA) and sodium citrate. Platelet count was obtained by an impedance haematology analyse...

Let X be a K3 surface which is intersection of three (i.e. a net P) of quadrics in P. The curve of degenerate quadrics has degree 6 and defines a natural double covering Y of P ramified in this curve which is again a K3. This is a classical example of a correspondence between K3 surfaces which is related with moduli of sheaves on K3’s studied by Mukai. When general (for fixed Picard lattices) X...

We have developed a model system for membrane fusion that utilizes lipidated derivatives of a heterodimeric coiled-coil pair dubbed E3 (EIAALEK)3 and K3 (KIAALKE)3. In this system, peptides are conjugated to a lipid anchor via a poly(ethylene glycol) (PEG) spacer, and this contribution studies the influence of the PEG spacer length, coupled with the type of lipid anchor, on liposome-liposome fu...

The e-learning platform K3 realizes a constructivist learning model augmented with collaborative properties. K3 courses, mainly offered since 2004 at the University of Konstanz, follow the blended learning model. K3 collaborative discourse work is organized in virtual groups. All group members have to choose a role (moderator, summarizer, etc.) for a certain period and their role performance is...
