The Evolution of the Protein Corona around Nanoparticles: A Test Study
The importance of the protein corona formed around nanoparticles upon entering a biological fluid has recently been highlighted. This corona is, when sufficiently long-lived, thought to govern the particles' biological fate. However, even this long-lived "hard" corona evolves and re-equilibrates as particles pass from one biological fluid to another, and may be an important feature for long-term f
Increased TRAb and/or Low Anti-TPO Titers at Diagnosis of Graves' Disease are Associated with an Increased Risk of Developing Ophthalmopathy after Onset.
Patients with low thyroid peroxidase antibodies (anti-TPO) and increased TSH-receptor antibodies (TRAb) at diagnosis of Graves' disease (GD) have been suggested to have an increased risk to develop Graves' ophthalmopathy (GO). The aim was to evaluate if GO development can be predicted.This is an observational study with registration of possible GD and GO risk factors.399 patients with GD were regi
Gas in Scattering Media Absorption Spectroscopy (GASMAS) Detected Persistent Vacuum in Apple Tissue After Vacuum Impregnation
The microstructure and the capillary pressure of the pore space are important variables for better understanding of the complex phenomena occurring during vacuum impregnation (VI) of plant tissues. In this study, we used GASMAS (Gas in Scattering Media Absorption Spectroscopy) of oxygen to, non-destructively, measure the dynamics of the internal pressure in apple pieces after restoration of the at
Distributed space-frequency coding for cooperative diversity over broadband relay channels with DF relaying
Multipath fading is one of the main challenges in transmission over wireless broadband relay channels due to frequency selectivity, which may deteriorate the received signal. Exploiting the extra source of multipath diversity, aside from cooperative (user) diversity, is important when coping with these wireless channel limitations. In this correspondence, we propose a new distributed space-frequen
Collagen VI Is Upregulated in COPD and Serves Both as an Adhesive Target and a Bactericidal Barrier for Moraxella catarrhalis.
Moraxella catarrhalis is a Gram-negative human mucosal commensal and pathogen. It is a common cause of exacerbation in chronic obstructive pulmonary disease (COPD). During the process of infection, host colonization correlates with recognition of host molecular patterns. Importantly, in COPD patients with compromised epithelial integrity the underlying extracellular matrix is exposed and provides
Gender and telomere length: Systematic review and meta-analysis.
It is widely believed that females have longer telomeres than males, although results from studies have been contradictory.
The Dark Side of the Swoon: antihypertensive treatment in the elderly.
We would like to thank Prof. Dal Moro for his valuable contribution[1]. Indeed, many patients, especially those who are older and who suffer from several concomitant diseases, are at risk of being "overtreated with good intentions". The main problem is that the diagnosis of essential hypertension is at times assigned very liberally based on a single ambulatory measurement without taking into consi
Human Fetal Striatum-Derived Neural Stem (NS) Cells Differentiate to Mature Neurons in Vitro and in Vivo.
Clonogenic neural stem (NS) cell lines grown in adherent cultures have previously been established from embryonic stem cells and fetal and adult CNS in rodents and from human fetal brain and spinal cord. Here we describe the isolation of a new cell line from human fetal striatum (hNS cells). These cells showed properties of NS cells in vitro such as monolayer growth, high proliferation rate and ex
Interactions between Cationic Lipid Bilayers and Model Chromatin
Complexes formed in mixtures of cationic liposomes of varying charge density and nucleosome core particles (NCPs) or nucleosome arrays have been characterized. Under most of the conditions studied, the lipids and NCPs or arrays formed lamellar structures similar to those obtained with the liposomes and pure DNA. Thus, the dissociation of DNA from the NCP or nucleosome array and the formation of a
Cleavage of IgG1 and IgG3 by gingipain K from Porphyromonas gingivalis may compromise host defense in progressive periodontitis.
Degradation of immunoglobulins is an effective strategy of bacteria to evade the immune system. We have tested whether human IgG is a substrate for gingipain K of Porphyromonas gingivalis and found that the enzyme can hydrolyze subclass 1 and 3 of human IgG. The heavy chain of IgG(1) was cleaved at a single site within the hinge region, generating Fab and Fc fragments. IgG(3) was also cleaved with
Finite volume and partially quenched QCD-like effective field theories
We present a calculation of the meson masses, decay constants and quark-antiquark vacuum expectation value for the three generic QCD-like chiral symmetry breaking patterns SU(N-F) x SU(N-F) -> SU(N-F)(V), SU(N-F) -> SO(N-F) and SU(2N(F)) -> Sp(2N(F)) in the effective field theory for these cases. We extend the previous two-loop work to include effects of partial quenching and finite volume. The ca
Outcome measures for primary Sjogren's syndrome
Lymphocytic infiltration of different exocrine and non-exocrine epithelia is the pathological hallmark of primary Sjogren's syndrome, whereas involvement of salivary and lachrymal glands with the clinical counterpart of dry eye and dry mouth are the predominant features of the disease, together with fatigue and musculoskeletal pain. In addition, systemic manifestations, like arthritis, skin vascul
Predicting C aromaticity of biochars based on their elemental composition
Three models were examined to predict C aromaticity (f(a)) of biochars based on either their elemental composition (C, H, N and O) or fixed C (FC) content. Values of f(a) from solid state C-13 nuclear magnetic resonance (NMR) analysis with Bloch-decay (BD) or direct polarisation (DP) techniques, concentrations of total C, H, N, and organic O, and contents of FC of 60 biochars were either compiled
Adapting to Climate Change in Swedish Planning Practice
Mitigation measures, especially municipal energy infrastructure transformation, have been the focus of Sweden’s climate change responses. Recently, adaptation measures have grown in priority and planners are challenged to integrate mitigation and adaptation. In our study, we observe how synergies and conflicts in adaptation, mitigation, and other social and economic dimensions of spatial planning
Implications for the origin of short gamma-ray bursts from their observed positions around their host galaxies
We present the observed offsets of short-duration gamma-ray bursts (SGRBs) from their putative host galaxies and compare them with the expected distributions of merging compact object binaries, given the observed properties of the hosts. We find that for all but one burst in our sample the offsets are consistent with this model. For the case of bursts with massive elliptical host galaxies, the cir
Expression of VEGF and Its receptors VEGFR1/VEGFR2 Is Associated with Invasiveness of Bladder Cancer.
Aim: Vascular endothelial growth factor (VEGF) signaling is frequently altered in invasive tumor cells and is associated with patient outcome. In the present study, we examined VEGF, VEGFR1, and VEGFR2 expression in non-muscle invasive bladder cancer (NMIBC) and muscle invasive bladder cancer (MIBC), and evaluated the association between VEGF and its receptors with disease characteristics and blad
Gastric bypass improves ss-cell function and increases β-cell mass in a porcine model.
The most frequently used, and effective, treatment for morbid obesity is Roux-en-Y gastric bypass surgery (RYGB), which results in rapid remission of T2D in most cases. To what extent this is accounted for by weight loss or other factors remains elusive. To gain insight into these mechanisms, we investigated the effects of RYGB on ß-cell function and ß-cell mass in the pig, a species highly remini
The global relationship between climate, net primary production and the diet of spiders
Aim We compiled data on prey utilization of spiders at a global scale to better understand the relationship between current climate or net primary production (NPP) and diet breadth, evenness and composition in spiders. We test whether the productivity and the diversity–climatic-stability (DCS) hypotheses focusing on diversity patterns may also explain global patterns in prey utilization by web-bui

OBJECTIVES: The aim of this study was to investigate for the first time the association between body fat and risk of amyotrophic lateral sclerosis (ALS) with an appropriate prospective study design. METHODS: The EPIC (European Prospective Investigation into Cancer and Nutrition) study included 518,108 individuals recruited from the general population across 10 Western European countries.
