Mapping free-energy landscapes has proved to be a powerful tool for studying reaction mechanisms. Many complex biomolecular assembly processes, however, have remained challenging to access using this approach, including the aggregation of peptides and proteins into amyloid fibrils implicated in a range of disorders. Here, we generalize the strategy used to probe free-energy landscapes in protein f
This chapter summarizes approaches to the detection of dryland vegetation change and methods for observing spatio-temporal trends from space. An overview of suitable long-term Earth Observation (EO) based datasets for assessment of global dryland vegetation trends is provided and a status map of contemporary greening and browning trends for global drylands is presented. The vegetation metrics suit
Background: Although chronic breathlessness is common in life-limiting illnesses, validated feasible instruments to measure functional impact of the symptom in this population are scarce. We aimed to validate the Dyspnea Exertion Scale (DES) compared with the modified Medical Research Council (mMRC) breathlessness scale for test-retest reliability, concurrent validity, and responsiveness in people
Many studies assume a respiratory quotient (RQ = CO2 produced per O2 consumed, by moles) of ~1 to calculate bacterial respiration from measured O2 consumption rates. However, the theoretical value of RQ varies with the elemental composition of the compound being decomposed. Photo-oxidation of DOC results in compounds of oxygen-rich organic acids which, theoretically, should result in elevated RQ.
Background: Chemotherapeutic efficacy can be improved by targeting the structure and function of the extracellular matrix (ECM) in the carcinomal stroma. This can be accomplished by e.g. inhibiting TGF-β1 and -β3 or treating with Imatinib, which results in scarcer collagen fibril structure in xenografted human KAT-4/HT29 (KAT-4) colon adenocarcinoma. Methods: The potential role of αVβ6 integrin-me
The subject matter of this paper is to unravel the ‘federal’ nature of proportionality in Union law. Does the principle of proportionality work as a safeguard of federalism or is it merely a legal tool for the Court to further market integration beyond the limits of the Treaty? If federalism refers to how powers are balanced and allocated between the central government and its constituent parts, i
PURPOSE: To propose and assess an improved method for calculating the equilibrium magnetization of arterial blood ( M0a), used for calibration of perfusion estimates in arterial spin labeling.METHODS: Whereas standard M0a calculation is based on dividing a proton density-weighted image by an average brain-blood partition coefficient, the proposed method exploits partial-volume data to adjust this
Quantum cascade lasers (QCLs) are generally designed to avoid negative differential conductivity (NDC) in the vicinity of the operation point in order to prevent instabilities. We demonstrate that the threshold condition is possible under an inhomogeneous distribution of the electric field (domains) and leads to lasing at an operation point with a voltage bias normally attributed to the NDC region
Importance: Childhood appendicitis is commonly complicated by gangrene and perforation, yet the causes of complicated appendicitis and how to avoid it remain unknown. Objective: To investigate whether children with IgE-mediated allergy have a lower risk of complicated appendicitis. Design, Setting, and Participants: This retrospective cohort study included all consecutive patients younger than 15
We study a system of spherical non-adsorbing particles immersed in a polydisperse polymer fluid. We derive an analytic expression for the many-body depletion interactions between the colloidal particles in the limit of very long chains. We argue that this expression is essentially exact for long chains and justify this using explicit simulations. In this way we are able to elucidate the profound e
BACKGROUND: Beans are rich and inexpensive sources of proteins and carbohydrates around the world, but particularly in developing countries. However, many legume varieties are still underutilized. In this study, physical characteristics of the seeds of three Phaseolus lunatus cultivars were characterized. Also, the chemical composition and starch digestibility in the cooked beans were assessed. RE
Emotion regulation group therapy (ERGT) is a novel treatment specifically targeting deliberate non-suicidal self-harm (DSH) in individuals with borderline personality disorder (BPD). Identifying robust predictors of positive response to ERGT could aid clinicians in treatment selection; however, to date, only one such study has been conducted. Thus, we aimed to replicate previously identified predi
This paper presents results from an experimental assessment of glued-in rods in cross laminated timber (CLT). For the purposes of the study more than 60 pull–pull tests were performed, where the specimens varied in terms of bonded-in length (from 80 to 400 mm), rod diameter (16–24 mm) and rod-to-grain angle (parallel and perpendicular). Several different failure modes that are not common for other
Hydrogen is an element of fundamental importance for energy but hard to quantify in bulk materials. Neutron radiography was used to map . in situ loss of elemental hydrogen from beech tree wood samples during pyrolysis. The samples consisted of three wood cylinders (finished dowel or cut branch) of approximately 1 cm in length. The samples were pyrolyzed under vacuum in a furnace vessel that was p
This study re-examines standard econometric approaches for detecting adverse and advantageous selection in insurance contracts based on variables that are not used for calculating the insurance premium. We formally demonstrate that existing strategies for detecting selection based on such ‘unused characteristics’ can lead to incorrect conclusions if the estimated coefficients of interest are drive
Protein stabilized emulsions made up of 40% soybean oil by weight and protein dispersions of 2.5% (w/w) protein content have been prepared in an ultrasonic device. The emulsifying apparatus was incorporated into a recirculating system, where power input and number of passes were varied. The food proteins studied were a soy bean protein isolate, a whey protein concentrate (WPC), and a sodium casein
Background and Purpose- In ischemic stroke, breakdown of the blood-brain barrier (BBB) aggravates brain damage. Pericyte detachment contributes to BBB disruption and neurovascular dysfunction, but little is known about its regulation in stroke. Here, we investigated how loss of RGS5 (regulator of G protein signaling 5) in pericytes affects BBB breakdown in stroke and its consequences. Method- We u
