Human TRPA1 is intrinsically cold- and chemosensitive with and without its N-terminal ankyrin repeat domain.

We have purified and reconstituted human transient receptor potential (TRP) subtype A1 (hTRPA1) into lipid bilayers and recorded single-channel currents to understand its inherent thermo- and chemosensory properties as well as the role of the ankyrin repeat domain (ARD) of the N terminus in channel behavior. We report that hTRPA1 with and without its N-terminal ARD (Δ1-688 hTRPA1) is intrinsically

Novel FOXF1 Mutations in Sporadic and Familial Cases of Alveolar Capillary Dysplasia with Misaligned Pulmonary Veins Imply a Role for its DNA Binding Domain

Alveolar capillary dysplasia with misalignment of pulmonary veins (ACD/MPV) is a rare and lethal developmental disorder of the lung defined by a constellation of characteristic histopathological features. Nonpulmonary anomalies involving organs of gastrointestinal, cardiovascular, and genitourinary systems have been identified in approximately 80% of patients with ACD/MPV. We have collected DNA an

Implications of accounting for land use in simulations of ecosystem carbon cycling in Africa

Dynamic global vegetation models (DGVMs) are important tools for modelling impacts of global change on ecosystem services. However, most models do not take full account of human land management and land use and land cover changes (LULCCs). We integrated croplands and pasture and their management and natural vegetation recovery and succession following cropland abandonment into the LPJ-GUESS DGVM.

Do pathological parameters differ with regard to breast density and mode of detection in breast cancer? The Malmö Diet and Cancer Study.

Our aim was to study how breast density relates to tumor characteristics in breast cancer with emphasis on mode of detection. Among 17,035 women in the Malmö Diet and Cancer Study 826 incident cases have been diagnosed (1991-2007). Data on tumor characteristics, mode of detection, and density at diagnosis were collected. Associations between density and tumor characteristics were analyzed using lo

Do entrance fees crowd out donations for public goods? Evidence from a protected area in Costa Rica

In this paper, we investigate how different levels of entrance fees affect donations for a public good, a natural park. To explore this issue, we conducted a stated preference study focusing on visitors' preferences for donating money to raise funds for a protected area in Costa Rica given different entrance fee levels. The results reveal that there is incomplete crowding out of donations when est

Linking chlorophyll biosynthesis to a dynamic plastoquinone pool.

Chlorophylls are essential cofactors in photosynthesis. All steps in the chlorophyll pathway are well characterized except for the cyclase reaction in which the fifth ring of the chlorophyll molecule is formed during conversion of Mg-protoporphyrin IX monomethyl ester into Protochlorophyllide. The only subunit of the cyclase identified so far, is AcsF (Xantha-l in barley and Chl27 in Arabidopsis).

Adipocyte Size is Associated with NAFLD Independent of Obesity, Fat Distribution, and PNPLA3 Genotype

Objective: Adipocyte hypertrophy has been suggested to be causally linked with inflammation and systemic insulin resistance. The aim of the study was to determine whether increased adipocyte size is associated with increased liver fat content due to nonalcoholic fatty liver disease (NAFLD) in humans independent of obesity, fat distribution and genetic variation in the patatin-like phospholipase do

Moraxella catarrhalis Evades Host Innate Immunity via Targeting Cartilage Oligomeric Matrix Protein.

Moraxella catarrhalis is a respiratory tract pathogen commonly causing otitis media in children and acute exacerbations in patients suffering from chronic obstructive pulmonary disease. Cartilage oligomeric matrix protein (COMP) functions as a structural component in cartilage, as well as a regulator of complement activity. Importantly, COMP is detected in resident macrophages and monocytes, alveo

Icatibant, a New Bradykinin-Receptor Antagonist, in Hereditary Angioedema

BACKGROUND Hereditary angioedema is characterized by recurrent attacks of angioedema of the skin, larynx, and gastrointestinal tract. Bradykinin is the key mediator of symptoms. Icatibant is a selective bradykinin B2 receptor antagonist. METHODS In two double-blind, randomized, multicenter trials, we evaluated the effect of icatibant in patients with hereditary angioedema presenting with cutaneous

Studies Toward Communesin F: A Diels-Alder Approach.

A Diels-Alder reaction is used as a key step in a synthetic study toward communesin F, in order to simultaneously introduce both of the all-carbon quaternary stereocenters with complete control of relative stereochemistry. Further manipulations of the cycloadduct, toward the hexacyclic core-structure of communesin F, are also disclosed.

Computerised assistance for warfarin dosage - Effects on treatment quality

Background: Well-managed warfarin treatment with a high time in therapeutic range (TTR) corresponds to fewer bleedings or thromboembolic complications. Many small centres manage their warfarin dosing manually, with little or no knowledge of their treatment quality as measured by TTR. AuriculA is a Swedish National web-based anticoagulation dosing system. Our hypothesis was that the web based dosin

Engaging the History of Religions - from an Islamic Studies Perspective

The future and relevance of the history of religions discipline in the Swedish context has been discussed lately. This article is a response to this debate from an Islamic studies perspective. The authors argue that the history of religions discipline may become more relevant if a more self-critical approach is adopted, an interdisciplinary attitude upheld, and if there is an openness to learn fro

Landlords' Experiences of Housing Tenants Suffering from Severe Mental Illness: A Swedish Empirical Study

The aim of this Swedish study was to describe landlords' experiences of having tenants suffering from severe mental illness. Sixteen landlords working in private and public housing agencies participated in open in-depth interviews. Data were subjected to a thematic latent content analysis. The results showed that having tenants with severe mental illness entails being confronted with various diffi

Feet on the ground: Physical support of the inner retina is a strong determinant for cell survival and structural preservation in vitro.

Purpose: The purpose of this study was to explore the importance of local physical tissue support for homeostasis in the isolated retina. Methods: Full-thickness retinal sheets were isolated from adult porcine eyes. Retinas were cultured for 5 or 10 days using the previously established explant protocol with photoreceptors positioned against the culture membrane (porous polycarbonate) or the Mülle

Iridium Catalyzed Carbocyclizations: Efficient (5+2) Cycloadditions of Vinylcyclopropanes and Alkynes.

Third-row transition metal catalysts remain a largely untapped resource in cycloaddition reactions for the formation of medium-sized rings. Herein, we report the first examples of iridium-catalyzed inter- and intramolecular vinylcyclopropane (VCP)-alkyne (5+2) cycloadditions. DFT modeling suggests that catalysis by iridium(I) proceeds through a mechanism similar to that previously reported for rho

Molecular mechanisms underlying deregulation of C/EBP alpha in acute myeloid leukemia

The CEBPA gene encodes a transcription factor protein that is crucial for granulocytic differentiation, regulation of myeloid gene expression and growth arrest. Mutations in one or both alleles of CEBPA are observed in about 10% of patients with acute myeloid leukemia (AML). Moreover, other genetic events associated with AML have been identified to deregulate C/EBP alpha expression and function at
