Developing a Collection of Immobilized Nucleoside Phosphorylases for the Preparation of Nucleoside Analogues: Enzymatic Synthesis of Arabinosyladenine and 2,3-Dideoxyinosine

The use of nucleoside phosphorylases (NPs; EC 2.4.2.n) represents a convenient alternative to the chemical route for the synthesis of natural and modified nucleosides. We purified four recombinantly expressed nucleoside phosphorylases from the bacterial pathogens Citrobacter koseri, Clostridium perfringens, and Streptococcus pyogenes (CkPNPI, CkPNPII, CpUP, SpUP) and their substrate specificity wa

A Stupidity-Based Theory of Organizations

In this paper we question the one-sided thesis that contemporary organizations rely on the mobilization of cognitive capacities. We suggest that severe restrictions on these capacities in the form of what we call functional stupidity are an equally important if under-recognized part of organizational life. Functional stupidity refers to an absence of reflexivity, a refusal to use intellectual capa

4f photoionization and subsequent Auger decay in atomic Pb: Relativistic effects

High-resolution 4f photoelectron and subsequent Auger-electron spectra have been measured from free Pb atoms using synchrotron radiation. The fine structure of the spectra has been investigated theoretically by calculating the energies and intensities for 4f photoionization and Auger decay processes using the multiconfigurational Dirac-Fock approach. The role of the relativistic effects in the gro

Reality versus fantasy: Reply to Lynn et al. (2014).

We respond to Lynn et al.'s (2014) comments on our review (Dalenberg et al., 2012) demonstrating the superiority of the trauma model (TM) over the fantasy model (FM) in explaining the trauma-dissociation relationship. Lynn et al. conceded that our meta-analytic results support the TM hypothesis that trauma exposure is a causal risk factor for the development of dissociation. Although Lynn et al. s

A new volume scanner

Optical imaging through complex biological media remains a very challenging task due to the extremely high scattering experienced. A new design scanner is proposed and modelled which images scatter spatio-temporally. Modeling confirms the performance of the design. The inversion algorithm to reconstruct the scattering object remains as future work.

The arcuate line hernia: operative treatment and a review of the literature.

PURPOSE: An arcuate line hernia (ALH) is a rare diagnosis with no consensus on how to deal with this condition either when symptomatic or when found accidentally. Suggestions for laparoscopic and open operative techniques are given together with a review of the literature and a presentation of three new cases. MATERIAL: The PubMed database was searched for publications on ALH. Identified cases, in

Validity of histology for the diagnosis of paediatric coeliac disease: a Swedish multicentre study.

Objective Histological evaluation of intestinal biopsies for the diagnosis of coeliac disease can be challenging and compatible with risk of misdiagnosis. The aim was to evaluate the agreement of pathological diagnosis for coeliac disease in children investigated at four major paediatric university hospitals in Sweden. Materials and methods Intestinal duodenal biopsies were collected from 402 chil

Novel Trial Designs: Lessons Learned from Thrombus Aspiration During ST-Segment Elevation Myocardial Infarction in Scandinavia (TASTE) Trial.

In ST-elevation myocardial infarction (STEMI), thrombus material is often present in partial or total coronary occlusion of the coronary vessel. However, prior to the thrombus aspiration during ST-Segment Elevation Myocardial Infarction in Scandinavia (TASTE) trial, it remained unclear whether routine thrombus aspiration during percutaneous coronary intervention (PCI) treatment of STEMI would resu

Differences between violent and non-violent adolescents in terms of sport background and sport-related psychological variables

To date, neither theoretical approaches nor empirical findings allow clear predictions about the influence of sport engagement on youth violence. The present study uses a typological approach to investigate groups of adolescents with different characteristics of violent behaviour and cognition regarding their sport background and psychological variables associated with violent behaviour. A sample

The immunological effect of revaccination with Bacille Calmette-Guerin vaccine at 19 months of age

Background: Bacille Calmette-Guerin (BCG) vaccination has important non-specific immune effects. In a randomized trial in Guinea-Bissau, BCG revaccination was associated with significantly increased survival in children who received diphtheria-tetanus-pertussis (DTP)-booster vaccine before enrolment and in children who did not receive micronutrient supplementation (MN). Within the trial we assesse

Prototype effect and the persuasiveness of generalizations

An argument that makes use of a generalization activates the prototype for the category used in the generalization. We conducted two experiments that investigated how the activation of the prototype affects the persuasiveness of the argument. The results of the experiments suggest that the features of the prototype overshadow and partly overwrite the actual facts of the case. The case is, to some

Fast reconstruction of harmonic functions from Cauchy data using integral equation techniques

We consider the problem of stable determination of a harmonic function from knowledge of the solution and its normal derivative on a part of the boundary of the (bounded) solution domain. The alternating method is a procedure to generate an approximation to the harmonic function from such Cauchy data and we investigate a numerical implementation of this procedure based on Fredholm integral equatio

Annexin-II, DNA and histones serve as Factor H ligands on the surface of apoptotic cells.

Apoptotic cells are opsonized by complement components such as C1q and C3b, which increases their susceptibility to phagocytosis. Soluble complement inhibitors such as factor H (fH)b also recognise apoptotic cells to minimize the pro-inflammatory effects of downstream complement activation. We used four radiolabelled protein constructs that span different regions of the 20 CCP modules that make up

Ocellar adaptations for dim light vision in a nocturnal bee

Growing evidence indicates that insect ocelli are strongly adapted to meet the specific functional requirements in the environment in which that insect lives. We investigated how the ocelli of the nocturnal bee Megalopta genalis are adapted to life in the dim understory of a tropical rainforest. Using a combination of light microscopy and three-dimensional reconstruction, we found that the retinae

HARMONY 3: 104-Week Randomized, Double-Blind, Placebo- and Active-Controlled Trial Assessing the Efficacy and Safety of Albiglutide Compared With Placebo, Sitagliptin, and Glimepiride in Patients With Type 2 Diabetes Taking Metformin.

To compare the efficacy and safety of weekly albiglutide with daily sitagliptin, daily glimepiride, and placebo.RESEARCH DESIGN AND METHODS: Patients with type 2 diabetes receiving metformin were randomized to albiglutide (30 mg), sitagliptin (100 mg), glimepiride (2 mg), or placebo. Blinded dose titration for albiglutide (to 50 mg) and glimepiride (to 4 mg) was based on predefined hyperglycemia c
