Algal chloroplast produced camelid VH H antitoxins are capable of neutralizing botulinum neurotoxin.

We have produced three antitoxins consisting of the variable domains of camelid heavy chain-only antibodies (VH H) by expressing the genes in the chloroplast of green algae. These antitoxins accumulate as soluble proteins capable of binding and neutralizing botulinum neurotoxin. Furthermore, they accumulate at up to 5% total soluble protein, sufficient expression to easily produce these antitoxins at scale from algae. The genes for the three different antitoxins were transformed into Chlamydomonas reinhardt...

Liver X Receptor Regulation of Thyrotropin-Releasing Hormone Transcription in Mouse Hypothalamus Is Dependent on Thyroid Status.

Reversing the escalating rate of obesity requires increased knowledge of the molecular mechanisms controlling energy balance. Liver X receptors (LXRs) and thyroid hormone receptors (TRs) are key physiological regulators of energetic metabolism. Analysing interactions between these receptors in the periphery has led to a better understanding of the mechanisms involved in metabolic diseases. However, no data is available on such interactions in the brain. We tested the hypothesis that hypothalamic LXR/TR inte...

Simulation of Force Spectroscopy Experiments on Galacturonic Acid Oligomers.

Pectins, forming a matrix for cellulose and hemicellulose, determine the mechanics of plant cell walls. They undergo salient structural changes during their development. In the presence of divalent cations, usually calcium, pectins can form gel-like structures. Because of their importance they have been the subject of many force spectroscopy experiments, which have examined the conformational changes and molecular tensions due to external forces. The most abundant unit present in the pectin backbone is poly...

Comparison of Four Methods to Assess Erosive Substance Loss of Dentin.

Erosion of dentin results in a complex multi-layered lesion. Several methods have been used to measure erosive substance loss of dentin, but were found to have only limited agreement, in parts because they assess different structural parameters. The present study compared the agreement of four different methods (transversal microradiography [TMR], Confocal Laser Scanning Microscopy [CLSM], Laser Profilometry [LPM] and modified Knoop Hardness measurement [KHM]) to measure erosive substance loss in vitro. Nin...

Current Incidence of Accidents on Austrian Ski Slopes.

Background: Alpine skiing and snowboarding are the most popular winter sports. These sports are also associated with a certain injury risk which, however, has steadily decreased during the past decades. During the winter season 2002/2003 the last large survey on ski injuries in Austria was performed. Among others, modern skiing equipment and optimized slope preparation may impact on the injury risk. We hypothesise that these changes may have led to a further decrease in ski injuries during the past decade. ...

Automatic camera-based identification and 3-D reconstruction of electrode positions in electrocardiographic imaging.

Abstract Electrocardiographic imaging (ECG imaging) is a method to depict electrophysiological processes in the heart. It is an emerging technology with the potential of making the therapy of cardiac arrhythmia less invasive, less expensive, and more precise. A major challenge for integrating the method into clinical workflow is the seamless and correct identification and localization of electrodes on the thorax and their assignment to recorded channels. This work proposes a camera-based system, which can l...

The emerging role of the peptidome in biomarker discovery and degradome profiling.

Abstract The peptidome represents the array of endogenous peptides that are present in both the intracellular and extracellular space of the body. Peptides are constantly generated in vivo by active synthesis, and by proteolytic processing of larger precursor proteins, often yielding protein fragments that mediate a variety of physiological functions. Given that aberrant proteolysis is a hallmark of many pathological diseases, many studies have now turned to the peptidome. Differential regulation of endogen...

Examining the shared and unique relationships among substance use and mental disorders.

Co-morbidity among use of different substances can be explained by a shared underlying dimensional factor. What remains unknown is whether the relationship between substance use and various co-morbid mental disorders can be explained solely by the general factor or whether there remain unique contributions of specific substances.

Expression of recombinant proteins by BEVS in a macula-like virus-free silkworm cell line.

We previously established the first Bombyx mori macula-like virus (BmMLV)-free cell line (BmVF cells) from a B. mori embryo. In this study, we evaluated the expression of recombinant proteins in BmVF cells using a B. mori nucleopolyhedrovirus (BmNPV)-derived expression vector. Our results showed that BmVF cells are susceptible to BmNPV, and both the promoter activity of the polyhedrin gene and the post-translated modifications of a recombinant protein are equivalent between BmMLV-negative BmVF and -positive...

The Prevalence of Intestinal Parasites is not Greater Among Individuals with IBS: a Population-Based Case-Control Study.

& Aims: The parasites Dientamoeba fragilis and Blastocystis have been detected in feces from patients with irritable bowel syndrome (IBS), so these parasites might be involved in IBS pathogenesis. We proposed that a higher prevalence of the parasites in IBS subjects compared to asymptomatic controls would support such a mechanism. We aimed to determine the prevalence of these parasites in IBS subjects (cases) and controls and to identify risk factors associated with parasite carriage.

The Reduced Effectiveness of Protected Areas under Climate Change Threatens Atlantic Forest Tiger Moths.

Climate change leads to species' range shifts, which may end up reducing the effectiveness of protected areas. These deleterious changes in biodiversity may become amplified if they include functionally important species, such as herbivores or pollinators. We evaluated how effective protected areas in the Brazilian Atlantic Forest are in maintaining the diversity of tiger moths (Arctiinae) under climate change. Specifically, we assessed whether protected areas will gain or lose species under climate change ...
