Exploration of H2 binding to the [NiFe]-hydrogenase active site with multiconfigurational density functional theory

The combination of density functional theory (DFT) with a multiconfigurational wave function is an efficient way to include dynamical correlation in calculations with multiconfiguration self-consistent field wave functions. These methods can potentially be employed to elucidate reaction mechanisms in bio-inorganic chemistry, where many other methods become either too computationally expensive or t

Protocol for a multi-site study of the effects of overdose prevention education with naloxone distribution program in Skåne County, Sweden

Background: Continuously high rates of overdose deaths in Sweden led to the decision by the Skåne County to initiate the first regional take-home naloxone program in Sweden. The project aims to study the effect of overdose prevention education and naloxone distribution on overdose mortality in Skåne County. Secondary outcome measures include non-fatal overdoses and overdose-related harm in the gen

PARP10 Multi-Site Auto- and Histone MARylation Visualized by Acid-Urea Gel Electrophoresis

Poly-ADP-ribose polymerase (PARP)-family ADP-ribosyltransferases function in various signaling pathways, predominantly in the nucleus and cytosol. Although PARP inhibitors are in clinical practice for cancer therapy, the enzymatic activities of individual PARP family members are yet insufficiently understood. We studied PARP10, a mono-ADP-ribosyltransferase and potential drug target. Using acid-ur

Putative ligand binding sites of two functionally characterized bark beetle odorant receptors

Background: Bark beetles are major pests of conifer forests, and their behavior is primarily mediated via olfaction. Targeting the odorant receptors (ORs) may thus provide avenues towards improved pest control. Such an approach requires information on the function of ORs and their interactions with ligands, which is also essential for understanding the functional evolution of these receptors. Henc

Novel Function of CtXyn5A from Acetivibrio thermocellus : Dual Arabinoxylanase and Feruloyl Esterase Activity in the Same Active Site

Uncharacterized side activities of enzymes can have significant effects on reaction products and yields. Hence, their identification and characterization are crucial for the development of successful reaction systems. Here, we report the presence of feruloyl esterase activity in CtXyn5A from Acetivibrio thermocellus, besides its well-known arabinoxylanase activity, for the first time. Activity ana

The Forward Physics Facility: Sites, experiments, and physics potential

The Forward Physics Facility (FPF) is a proposal to create a cavern with the space and infrastructure to support a suite of far-forward experiments at the Large Hadron Collider during the High Luminosity era. Located along the beam collision axis and shielded from the interaction point by at least 100 m of concrete and rock, the FPF will house experiments that will detect particles outside the acc

Novel Function of CtXyn5A from Acetivibrio thermocellus: Dual Arabinoxylanase and Feruloyl Esterase Activity Occur in the Same Active Site

Uncharacterized side activities of enzymes can have significant negative effects on reaction products and yields. Hence, their identification and characterization is crucial for the development of successful reaction systems. Here, we report the presence of feruloyl esterase activity in CtXyn5A from Acetivibrio thermocellus besides its well-known arabinoxylanase activity for the first time. Both r

Secondary nucleation and elongation occur at different sites on Alzheimer's amyloid-b aggregates

The aggregates of the Ab peptide associated with Alzheimer's disease are able to both grow in size aswell as generate, through secondary nucleation, new small oligomeric species, that are major cytotoxins associated with neuronal death. Despite the importance of these amyloid fibril-dependent processes, their structural and molecular underpinnings have remained challenging to elucidate. Here, we c

Geoelectrical imaging for site investigation for urban underground infrastructure : a TRUST-project

Unforeseen ground conditions are risk factors often leading to delays and significant additional costs in conjunction with underground infrastructure construction work. There are two main geological hazards that are important to identify, manage, or possibly avoid, for safe and efficient underground construction. The first is unstable rock and the second is large groundwater inflow. The latter exi

Reduced Carbon Monoxide Saturation Coverage on Vicinal Palladium Surfaces : The Importance of the Adsorption Site

Steps at metal surfaces may influence energetics and kinetics of catalytic reactions in unexpected ways. Here, we report a significant reduction of the CO saturation coverage in Pd vicinal surfaces, which in turn is relevant for the light-off of the CO oxidation reaction. The study is based on a systematic investigation of CO adsorption on vicinal Pd(111) surfaces making use of a curved Pd crystal

An Architecture for Integrated Test Data Compression and Abort-on-Fail Testing in a Multi-Site Environment

The semiconductor technology development makes it possible to fabricate increasingly advanced integrated circuits (ICs). However, because of imperfections at manufacturing, each individual IC must be tested. A major problem at IC manufacturing test is the increasing test data volume as it leads to high automatic test equipment (ATE) memory requirement, long test application time and low throughput

Contractions induce phosphorylation of the AMPK site Ser(565) in hormone-sensitive lipase in muscle

Intramyocellular triglyceride is an important energy store which is related to insulin resistance. Mobilization of fatty acids from this pool is probably regulated by hormone-sensitive lipase (HSL), which has recently been shown to exist in muscle and to be activated by epinephrine via PKA and by contractions via PKC and ERK. 5' AMP-activated protein kinase (AMPK) is an intracellular fuel gauge wh

Surface-associated lipid droplets : an intermediate site for lipid transport in human adipocytes?

Adipose tissue plays a major role in regulating whole-body energy metabolism. While the biochemical processes regulating storage and release of excess energy are well known, the temporal organization of these events is much less defined. In this study, we have characterized the presence of small surface-associated lipid droplets, distinct from the central droplet, in primary human adipocytes. Base

Haemophilus Protein F Orthologs of Pathogens Infecting the Airways : Exploiting Host Laminin at Heparin-Binding Sites for Maximal Adherence to Epithelial Cells

Haemophilus influenzae protein F (PF) is an important virulence factor interacting with laminin, an extracellular matrix protein ubiquitously expressed in the respiratory tract. Here we defined PF orthologs in Pseudomonas aeruginosa, Moraxella catarrhalis, and Staphylococcus aureus, bacteria that occasionally colonize and infect the human airways. Despite low sequence homology (48.2%-77.3% similar
