A Heteroleptic Ferrous Complex with Mesoionic Bis(1,2,3-triazol-5-ylidene) Ligands: Taming the MLCT Excited State of Iron(II).

Strongly σ-donating N-heterocyclic carbenes (NHCs) have revived research interest in the catalytic chemistry of iron, and are now also starting to bring the photochemistry and photophysics of this abundant element into a new era. In this work, The efficient synthesis of a heteroleptic Fe(II) complex (1) is based on sequentially furnishing the Fe(II) center with the benchmark 2,2'-bipyridine (bpy)

Aggregation Behavior of Bovine kappa- and beta-Casein Studied with Small Angle Neutron Scattering, Light Scattering, and Cryogenic Transmission Electron Microscopy

In the native bovine casein micelle the calcium sensitive caseins (alpha(S1)-, alpha(S2)- and beta-casein) sequester amorphous calcium phosphate in nanometer-sized clusters, whereas the calcium-insensitive K-casein limits the growth of the micelle. In this paper, we further investigate the self-association of kappa- and beta-casein, which are two of the key proteins that control the substructure o

Prediction Models for Assessing Long-Term Outcome in Alzheimer's Disease: A Review.

In Alzheimer's disease (AD), placebo-controlled long-term studies of cholinesterase inhibitors (ChEIs) are not permitted for ethical reasons. Therefore, in these studies, patients' outcomes on cognitive and functional assessment scales must be compared with mathematical models or historical data from untreated cohorts. PubMed and previously published long-term extensions of clinical trials and nat

LifeGene-a large prospective population-based study of global relevance

Studying gene-environment interactions requires that the amount and quality of the lifestyle data is comparable to what is available for the corresponding genomic data. Sweden has several crucial prerequisites for comprehensive longitudinal biomedical research, such as the personal identity number, the universally available national health care system, continuously updated population and health re

Specific subsets of mesenchymal stroma cells to treat lung disorders - Finding the Holy Grail.

Accumulating studies, both in animals and human clinical trials with mesenchymal stroma cells (MSC) support the hypothesis of therapeutic effects of these cells in various disorders. However, despite success in immune-mediated disorders such as Crohns' disease, lung disorders such as chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary disease (IPF) treated with MSC have so far no

Peptidylarginine Deiminases Present in the Airways During Tobacco Smoking and Inflammation can Citrullinate the Host Defense Peptide LL-37 Resulting in Altered Activities.

Bacterial colonization of the lower respiratory tract is frequently seen in COPD and may cause exacerbations leading to deterioration of the disease. An important part of the innate lung immunity is antimicrobial peptides, not least the cathelicidin hCAP-18/LL-37. Peptidylarginine deiminases (PADI) posttranslationally modifies proteins by converting cationic peptidylarginine residues to neutral pe

Doping Incorporation in InAs nanowires characterized by capacitance measurements

Sn and Se doped InAs nanowires are characterized using a capacitance-voltage technique where the threshold voltages of nanowire capacitors with different diameter are determined and analyzed using an improved radial metal-insulator-semiconductor field-effect transistor model. This allows for a separation of doping in the core of the nanowire from the surface charge at the side facets of the nanowi

TGIF1 is a negative regulator of MLL-rearranged acute myeloid leukemia.

Members of the TALE (Three-amino acid loop extension) family of atypical homeodomain-containing transcription factors are important downstream effectors of oncogenic fusion proteins involving the mixed lineage leukemia (MLL) gene. A well-characterized member of this protein family is MEIS1, which orchestrates a transcriptional program required for the maintenance of MLL-rearranged acute myeloid le

Neighborhood deprivation and prostate cancer mortality: a multilevel analysis from Sweden.

Background:The objective was to analyze the association between neighborhood deprivation and prostate cancer mortality, after adjusting for individual characteristics.Methods:This study was designed as a follow-up study of prostate cancer mortality between 1 January 1990 and 31 December 2008 in patients aged 25-74 years (a total of 73 159 patients). Multilevel logistic regression analyses were per

Genome-wide association studies of late-onset cardiovascular disease.

Human genetics is a powerful tool for discovering causal mediators of human disease and physiology. Cardiovascular diseases with late onset in the lifecourse have historically not been considered genetic diseases, but in recent years the contribution of a heritable factor has been established. More importantly, over the last decade genome-wide association studies (GWASs) have identified many loci

Long-term work disability in patients with psoriatic arthritis treated with anti-tumour necrosis factor: a population-based regional Swedish cohort study.

OBJECTIVE: To study long-term work disability before and after tumour necrosis factor (TNF)-antagonist therapy in patients with psoriatic arthritis (PsA). METHODS: Using the population-based South Swedish Arthritis Treatment Group Register, we identified 191 patients with PsA (median age 43 years, range 18-58 years, 54% men), who between January 2003 and December 2007 started treatment with adalim

Increased burden on caregivers of having a child with haemophilia complicated by inhibitors.

Having a child with a chronic disease often increases the burden in the family with more hospital visits, treatment administration, and increased worries for the ill child. A cross-sectional, international, multi-centre study in caregivers of children <18 years with haemophilia and inhibitor was performed at Haemophilia Treatment Centres in Sweden, UK, and Canada to evaluate caregivers' burden and

Effect of multiplicity, laterality, and age at onset of breast cancer on familial risk of breast cancer: a nationwide prospective cohort study

The objective of this nationwide prospective cohort study is to find out the risk of breast cancer (BC) in relatives of patients with multiple BCs by laterality and age at diagnosis of first BC. Having family history of single (HR 1.8; 95 % CI 1.8-1.9) or multiple (HR 2.7; 95 % CI 2.6-2.9) BC was associated with higher risk of BC. Those with an FDR with contralateral BC at any age had the highest

Mild cognitive impairment and deficits in instrumental activities of daily living: a systematic review.

Introduction: There is a growing body of evidence that subtle deficits in instrumental activities of daily living (IADL) may be present in mild cognitive impairment (MCI). However, it is not clear if there are IADL domains that are consistently affected across patients with MCI. In this systematic review, therefore, we aimed to summarize research results regarding the performance of MCI patients i

Application of a dye-binding method for the determination of available lysine in skim milk powders.

A dye-binding method using Acid Orange 12 was investigated regarding its suitability for the quantification of available lysine, as a means of monitoring the Maillard reaction in skim milk powders. The method was evaluated by analyzing a wide range of milk powders produced by three different drying methods and stored under various conditions. A pilot-scale freeze-dryer, spray-dryer and drum-dryer

High current density Esaki tunnel diodes based on GaSb-InAsSb heterostructure nanowires

We present electrical characterization of broken gap GaSb-InAsSb nanowire heterojunctions. Esaki diode characteristics with maximum reverse current of 1750 kA/cm2 at 0.50 V, maximum peak current of 67 kA/cm2 at 0.11 V, and peak-to-valley ratio (PVR) of 2.1 are obtained at room temperature. The reverse current density is comparable to that of state-of-the-art tunnel diodes based on heavily doped p-
