The Effects of Chain Length on the Structural Properties of Intrinsically Disordered Proteins in Concentrated Solutions

Intrinsically disordered proteins (IDP) are proteins that sample a heterogeneous ensemble of conformers in solution. An estimated 25-30% of all eukaryotic proteins belong to this class. In vivo, IDPs function under conditions that are highly crowded by other biological macromolecules. Previous research has highlighted that the presence of crowding agents can influence the conformational ensemble s

Creation and Annihilation of Nonradiative Recombination Centers in Polycrystalline Metal Halide Perovskites by Alternating Electric Field and Light

Metal halide perovskites are promising optoelectronic materials. Their electronic properties however are rather unstable which is often assigned to ion migration. Ion migration can be readily influenced by an electric field (EF). Here, the response of photoluminescence (PL) of individual MAPbX3 (MA = CH3NH3, X = I, Br) sub-micrometer-sized polycrystals to EF is studied. Alternating EF with frequen

Secretion of iron(III)-reducing metabolites during protein acquisition by the ectomycorrhizal fungus paxillus involutus

The ectomycorrhizal fungus Paxillus involutus decomposes proteins using a two-step mechanism, including oxidation and proteolysis. Oxidation involves the action of extracellular hydroxyl radicals (•OH) generated by the Fenton reaction. This reaction requires the presence of iron(II). Here, we monitored the speciation of extracellular iron and the secretion of iron(III)-reducing metabolites during

Revealing vibronic coupling in chlorophyll c1 by polarization-controlled 2D electronic spectroscopy

Vibronic coupling between molecules has been recently discussed to play an important role in photosynthetic functions. Furthermore, this type of coupling between electronic states has been suggested to define photophysical properties of chlorophylls, a family of photosynthetic molecules. However, experimental investigation of vibronic coupling presents a major challenge. One subtle way to study vi

Global distribution network design: exploration of facility location driven by tax considerations and related cross-country implications

Multinational corporations (MNCs) are moving not only their headquarters but also their logistics operations to low-tax jurisdictions to minimise the tax burden. However, the logistics andfiscal domains are guided by different principles. This study aims to explore the cross-country implications of locating facilities in low-tax jurisdictions to takeadvantage of tax arbitrage. A single case study

Comorbid amyloid-β pathology affects clinical and imaging features in VCD

Introduction: To date, the clinical relevance of comorbid amyloid-β (Aβ) pathology in patients with vascular cognitive disorders (VCD) is largely unknown. Methods: We included 218 VCD patients with available cerebrospinal fluid Aβ42 levels. Patients were divided into Aβ+ mild-VCD (n = 84), Aβ− mild-VCD (n = 68), Aβ+ major-VCD (n = 31), and Aβ− major-VCD (n = 35). We measured depression with the Ge

Blockchain Technology and Trust in Supply Chain Management: A Literature Review and Research Agenda

Applying blockchain technology for information sharing in supply chain is driven by many factors, but developing trust is one of the most proposed. However, trust is a multidimensional, intangible concept without an agreed-upon definition. Whereas some argue that trust is the main driver of blockchain technology, others have found a negative relationship. This study focuses on how applying blockch

Cervical cancer among Swedish women with drug use disorders : A nationwide epidemiological study

Background/Aim: Cervical cancer incidence and mortality has decreased after introduction of national screening in Sweden, but women with drug use disorders (DUD) are less likely to participate in screening programs. We aimed to investigate cervical cancer incidence and mortality among women with DUD compared to the general female population in Sweden. Methods: We conducted a cohort study based on

Implementing the urban food–water–energy nexus through urban laboratories : a systematic literature review

The sustainability of complex resource systems, such as the food, water, and energy (FWE) nexus, is increasingly threatened by climate change impacts, expanding populations, urbanization, and economic instability. However, while research on the topic has burgeoned, studies focused on solution development and implementation, especially at the urban level, have lagged behind. Against this background

Pleiotropic anticoagulant functions of protein S, consequences for the clinical laboratory. Communication from the SSC of the ISTH

Hereditary deficiencies of protein S (PS) increase the risk of thrombosis. However, assessing the plasma levels of PS is complicated by its manifold physiological interactions, while the large inter-individual variability makes it problematic to establish reliable cut-off values. PS has multiple physiological functions, with only two appearing to have significant anticoagulant properties: the acti

Pathological insight into 5-ht2b receptor activation in fibrosing interstitial lung diseases

Interstitial lung disease (ILD) encompasses a heterogeneous group of more than 200 con-ditions, of which primarily idiopathic pulmonary fibrosis (IPF), idiopathic nonspecific interstitial pneumonia, hypersensitivity pneumonitis, ILD associated with autoimmune diseases and sarcoidosis may present a progressive fibrosing (PF) phenotype. Despite different aetiology and histopathological patterns, the

Acoustic cell patterning in hydrogel for three-dimensional cell network formation

In the field of engineered organ and drug development, three-dimensional network-structured tissue has been a long-sought goal. This paper presents a direct hydrogel extrusion process exposed to an ultrasound standing wave that aligns fibroblast cells to form a network structure. The frequency-shifted (2 MHz to 4 MHz) ultrasound actuation of a 400-micrometer square-shaped glass capillary that was

Heritagelore and an Introduction to the Thematic Issue on Culture and Heritage Under Construction

Taking inspiration in Barbro Klein’s work, this article focuses on the production of a particular type of institutional lore that we call heritagelore. Heritagelore, as we are advancing the concept here, is composed of the discursive practices within the walls and the organizations of museums. It is the lore that shapes and at least partially structures the types of stories that directors, museum
