Antiinflammatory and Anticancer Properties of Grewia asiatica Crude Extracts and Fractions : A Bioassay-Guided Approach

The study was an extension of our earlier work on antiinflammatory and anticancer properties of G. asiatica fruit. We aimed to develop a bioassay guided multistep purification technique for producing bioactive fractions of G. asiatica crude extracts. Dried fruit powder was sequentially fractionated with 100% dichloromethane, 100% methanol (MeOH), and 50% MeOH. Active extracts were subjected to liq

A Mixture of Endocrine Disrupting Chemicals Associated with Lower Birth Weight in Children Induces Adipogenesis and DNA Methylation Changes in Human Mesenchymal Stem Cells

Endocrine disrupting chemicals (EDCs) are man-made compounds that alter functions of the endocrine system. Environmental mixtures of EDCs might have adverse effects on human health, even though their individual concentrations are below regulatory levels of concerns. However, studies identifying and experimentally testing adverse effects of real-life mixtures are scarce. In this study, we aimed at

Partial Monosomy 21 Mirrors Gene Expression of Trisomy 21 in a Patient-Derived Neuroepithelial Stem Cell Model

Induced pluripotent stem cells (iPSCs) from patients are an attractive disease model to study tissues with poor accessibility such as the brain. Using this approach, we and others have shown that trisomy 21 results in genome-wide transcriptional dysregulations. The effects of loss of genes on chromosome 21 is much less characterized. Here, we use patient-derived neural cells from an individual wit

α-Synuclein Interaction with Lipid Bilayer Discs

α-Synuclein (aSyn) is a 140 residue long protein present in presynaptic termini of nerve cells. The protein is associated with Parkinson's disease, in which case it has been found to self-Assemble into long amyloid fibrils forming intracellular inclusions that are also rich in lipids. Furthermore, its synaptic function is proposed to involve interaction with lipid membranes, and hence, it is of in

Radiopaque dyes allow vessel imaging in lung tissue using laboratory phase contrast micro-CT

Phase contrast micro-CT is a powerful technique allowing imaging of soft tissue at synchrotrons or using lab- oratory sources. The use of contrast agents is a useful approach when imaging vascular structures. However, common x-ray contrast agents typically rely on heavy metals to increase absorption, which may affect the phase contrast and cause artifacts in the reconstructed volumes. Thus, utiliz

Coding for intangible competitive advantage - mapping the distribution and characteristics of software-developing firms in the Swedish economy

Software is at the core of digitalisation and is often claimed to play a central role in innovation and in shaping competition across industries and firms. There are yet few studies of the extent and nature of software development across firms. We employ a unique firm-level survey comprising 3,929 firms across Sweden to analyse the distribution and characteristics of firms that invest in software

A Borosilicide with Clathrate VIII Structure

The high-pressure phase Na8BxSi46-x(3 < x < 5) is the first representative of a borosilicide crystallizing in the rarely occurring clathrate VIII type structure. Crystals with composition Na8B4Si42(space group I43¯ m; a = 9.7187(2) Å Pearson symbol cI54) were obtained at 5-8 GPa and 1200 K. The clathrate I modification exists for the same composition at lower pressure with a larger cell volume (Pm

Graphene as an Adsorption Template for Studying Double Bond Activation in Catalysis

Hydrogenated graphene (H-Gr) is an extensively studied system not only because of its capabilities as a simplified model system for hydrocarbon chemistry but also because hydrogenation is a compelling method for Gr functionalization. However, knowledge of how H-Gr interacts with molecules at higher pressures and ambient conditions is lacking. Here we present experimental and theoretical evidence t

Towards a Circular Building Industry

The building industry has a major environmental impact in terms of global energy use, carbon emissions, resource use, and the production of waste. To reach ambitious international environmental goals, the building industry faces a need for large-scale change. Circular strategies for buildings include using building and materials longer through lifetime extension strategies, reuse, sharing, renovat

Right ventricular longitudinal function is linked to left ventricular filling pressure in patients with repaired tetralogy of fallot

Experimental data on pulmonary regurgitation has linked right ventricular longitudinal function to left ventricular filling pressure in animals with induced and treated pulmonary regurgitation but this relationship has not been investigated in patients with repaired Tetralogy of Fallot (rToF). The aim of this study was to determine if right ventricular longitudinal function assessed using cardiova

Dynamic analysis of forces in the lumbar spine during bag carrying

Objective. The intervertebral disc supports axial and shear forces generated during tasks such as lifting and carrying weights. The objective of this study was to determine the forces in the lumbar spine of workers carrying a bag on the head, on the shoulder and on the anterior part of the trunk. Methods. Kinematic measurements were recorded for 10 subjects carrying bags of 10, 20 and 25 kg on eac

Prediction of Indoor Environmental Quality Using a Regression Model for Educational Buildings in Hot Arid Climate : A Case Study in the Al-Najaf Technical Institute – Iraq

In hot climates, achieving a good indoor environmental quality (IEQ) in existing buildings is important especially with climate change challenges as future heat waves will increase in frequency, duration, and intensity. In educational buildings, there is much more focus on the IEQ parameters and the interactions among them that need to be in line with the continuously changing learning environment

Pre-Treatment Integrase Inhibitor Resistance and Natural Polymorphisms among HIV-1 Subtype C Infected Patients in Ethiopia

Dolutegravir-based antiretroviral therapy (ART) has been scaled up in many developing countries, including Ethiopia. However, subtype-dependent polymorphic differences might influence the occurrence of HIV-drug-resistance mutations (HIVDRMs). We analyzed the prevalence of pre-treatment integrase strand transfer inhibitor (INSTI) HIVDRMs and naturally occurring polymorphisms (NOPs) of the integrase

An Inclusive Leadership Framework to Foster Employee Creativity in the Healthcare Sector : The Role of Psychological Safety and Polychronicity

Creativity at the level of employees is of utmost importance for every sector of an economy, with no exception to a healthcare system. The reason why employee creativity is important lies in the fact that employees have profound knowledge of their job and thus can serve as a source of meaningful innovation in an organization. Research shows that employee creativity is largely dependent on leadersh

Architecture of topic

This volume contains innovative papers that target the linguistic status of topic at the interface between grammar and discourse. The purpose of the volume is to discuss the universal properties of topics and, at the same time, to document the range of discourse-semantic and grammatical variation within this phenomenon in European languages. The volume is structured accordingly: (i) theoretical fo
