Direct Electron-Transfer Anisotropy of a Site-Specifically Immobilized Cellobiose Dehydrogenase

To study the direct electron transfer (DET) of the multicofactor enzyme cellobiose dehydrogenase (CDH) in regard to its orientation on an electrode surface, a recently published, maleimide-based immobilization method was used in combination with site-directed mutagenesis to establish different orientations on an electrode surface. CDH from Myriococcum thermophilum was chosen for this study because

M&As in Africa – effects of law and governance

Purpose: The cultural and legal differences between foreign acquirers and African target firms can be substantial. There is also a large variation in cultures and legal systems within Africa. However, there is limited research on merger and acquisition (M&A) performance by foreign firms in Africa. The purpose of this paper is to fill this gap by exploring the “spillover by law” hypothesis (Mar

Hypotheses and tracking results about the longest migration : The case of the arctic tern

The arctic tern Sterna paradisaea completes the longest known annual return migration on Earth, traveling between breeding sites in the northern arctic and temperate regions and survival/molt areas in the Antarctic pack-ice zone. Salomonsen (1967, Biologiske Meddelelser, Copenhagen Danske Videnskabernes Selskab, 24, 1) put forward a hypothetical comprehensive interpretation of this global migratio

Establishing strong imputation performance of a denoising autoencoder in a wide range of missing data problems

Dealing with missing data in data analysis is inevitable. Although powerful imputation methods that address this problem exist, there is still much room for improvement. In this study, we examined single imputation based on deep autoencoders, motivated by the apparent success of deep learning to efficiently extract useful dataset features. We have developed a consistent framework for both training

Unexpected positive patch test reactions to sesquiterpene lactones in patients sensitized to the glucose sensor FreeStyle Libre

Background: Most diabetic patients sensitized to FreeStyle Libre react to isobornyl acrylate (IBOA), with a considerable number of them also showing unexpected positive patch test reactions to sesquiterpene lactone (SL) mix (SLM) tested in the baseline series. Objectives: To compile patch test results of subjects affected, and provide potential explanations for this association. Patients and Metho

Patient registries for home oxygen research and evaluation

Randomized clinical trials are the preferred study design to address key research questions about the benefits or harms of interventions. However, randomized trials of oxygen therapy are difficult to conduct and have limitations. The purpose of this article is to offer our view on the potential use of patient registries in the field of home oxygen in COPD as an alternative to randomized trials by

A Recommender System for User-Specific Vulnerability Scoring

With the inclusion of external software components in their software, vendors also need to identify and evaluate vulnerabilities in the components they use. A growing number of external components makes this process more time-consuming, as vendors need to evaluate the severity and applicability of published vulnerabilities. The CVSS score is used to rank the severity of a vulnerability, but in its

Women in Stem Cell Science: Part I

Female scientists play important leadership roles in the field and with the International Society for Stem Cell Research. We asked a number of these top researchers to share their personal stories and reflect on their career paths. Part II of this series will run in the October 2018 issue of Stem Cell Reports.

Burden of Atopic Dermatitis in Swedish Adults : A Population-based Study

The burden of atopic dermatitis (AD) was assessed. A population-based, cross-sectional questionnaire study was performed among 34,313 Swedish adults in 2017. The prevalence of AD was 14%. Adults with mild AD had an increased relative risk ratio (RRR) of severe depression (aRRR 1.78, 95% confidence interval (95% CI) 1.50–2.12) and anxiety (aRRR 1.97, 95% CI 1.69–2.30), which was higher for severe A

Growing up with a disability following paralytic poliomyelitis : experiences from persons with late effects of polio

Purpose: To describe the experiences of growing up after acute paralytic poliomyelitis and strategies used to adapt to the new situation. Methods: Seven women and seven men (mean age 70 years, min–max 61–78 years) with late effects of polio, who had contracted paralytic polio in their childhood. Data were collected using semi-structured interviews, transcribed verbatim, and analyzed by systematic

Green Transformation: Lessons from the Fuel Cell Innovation System in Taiwan

This study applies the technological innovation system framework to the case of the fuel cell sector in Taiwan. Many Asian latecomers, such as Taiwan, tend to adopt a top-down approach to emphasize the importance of environmental issues but the result is limited. We aim to take Taiwan’s fuel cell innovation system as an example to explore why Taiwan has formulated a technological innovation system

Analysis of heat transfer and fluid flow of a slot jet impinging on a confined concave surface with various curvature and small jet to target spacing

Purpose: This study aims to focus on the surface curvature, jet to target spacing and jet Reynolds number effects on the heat transfer and fluid flow characteristics of a slot jet impinging on a confined concave target surface at constant jet to target spacing. Design/methodology/approach: Numerical simulations are used in this research. Jet to target spacing, H/B is varying from 1.0 to 2.2, B is

Societal cost of oropharyngeal cancer by human papillomavirus status, cancer stage, and subsite

Background The incidence of oropharyngeal cancer (OPC) is increasing, particularly human papillomavirus (HPV)-associated OPC. The aim of this study was to specify the total societal cost of OPC by HPV status, cancer stage, and subsite using a bottom-up cost-of-illness approach. Methods We analyzed 121 consecutive patients with OPC from the Southern Health Care Region of Sweden. We estimated the di

Evaluating Nutrient Reduction, Grazing and Barley Straw as Measures Against Algal Growth

The aim of our study was to experimentally investigate whether it is possible to reduce nuisance growth of filamentous algae in freshwater ecosystems. We used an experimental set-up mimicking a shallow pond system and performed a field investigation in the eutrophic moat of Krapperup castle (Southern Sweden), which exemplifies an extremely impaired ecosystem with ample growth of filamentous green

Browning of freshwaters : Consequences to ecosystem services, underlying drivers, and potential mitigation measures

Browning of surface waters, as a result of increasing dissolved organic carbon and iron concentrations, is a widespread phenomenon with implications to the structure and function of aquatic ecosystems. In this article, we provide an overview of the consequences of browning in relation to ecosystem services, outline what the underlying drivers and mechanisms of browning are, and specifically focus

Convergent Synthesis of the Hexasaccharide Repeating Unit of the O-Antigenic OPS of Escherichia coli O133

Synthesis of the hexasaccharide repeating unit of the O-antigen from E. coli O133 has been accomplished with rational protecting group manipulations on commercially available monosaccharides and stereoselective glycosylations through a convergent protocol. A late stage TEMPO mediated oxidation is used to install the required uronic acid moiety. Chloroacetate group is used extensively as a temporar

Distribution of Locoregional Breast Cancer Recurrence in Relation to Postoperative Radiation Fields and Biological Subtypes

Purpose: To investigate incidence and location of locoregional recurrence (LRR) in patients who have received postoperative locoregional radiation therapy (LRRT) for primary breast cancer. LRR-position in relation to applied radiotherapy and the primary tumor biological subtype were analyzed with the aim of evaluating current target guidelines and radiation therapy techniques in relation to tumor
