The PEF family proteins sorcin and grancalcin interact in vivo and in vitro

The penta-EF hand (PEF) family of calcium binding proteins includes grancalcin, peflin, sorcin, calpain large and small subunits as well as ALG-2. Systematic testing of the heterodimerization abilities of the PEF proteins using the yeast two-hybrid and glutathione S-transferase pull-down assays revealed the new finding that grancalcin interacts strongly with sorcin. In addition, sorcin and grancal

Dietary intake of fish contaminated with persistent organochlorine compounds in relation to low birthweight

OBJECTIVES: The purpose of this study was to assess the hypothesized association between persistent organochlorine compounds through the consumption of fatty fish from the Baltic Sea (at the Swedish east coast) and low birthweight.MATERIALS AND METHODS: During the period 1973-1991, 72 cases of low birthweight (1500-2750 g) were selected from among infants born to fishermen's wives within a cohort

Phosphodiesterase 7 inhibitor reduced cognitive impairment and pathological hallmarks in a mouse model of Alzheimer's disease

Elevated levels of amyloid beta (Aβ) peptide, hyperphosphorylation of tau protein, and inflammation are pathological hallmarks in Alzheimer's disease (AD). Phosphodiesterase 7 (PDE7) regulates the inflammatory response through the cyclic adenosine monophosphate signaling cascade, and thus plays a central role in AD. The aim of this study was to evaluate the efficacy of an inhibitor of PDE7, named

Synthesis, Characterization, and Reactivity of PCN Pincer Nickel Complexes

New diamagnetic nickel(II) complexes based on an unsymmetrical (1-(3-((ditert-butylphosphino)methyl)phenyl)-N,N-dimethyl-methanamine) (PCN) pincer ligand were synthesized and characterized by 1H, 31P{1H}, and 13C{1H} NMR spectroscopy. Their molecular structures were confirmed by X-ray diffraction. Oxidation to high-valent paramagnetic Ni(III) dihalide complexes was achieved through straightforward

High Hydrostatic Pressure Induces a Lipid Phase Transition and Molecular Rearrangements in Low-Density Lipoprotein Nanoparticles

Low-density lipoproteins (LDL) are natural lipid transporter in human plasma whose chemically modified forms contribute to the progression of atherosclerosis and cardiovascular diseases accounting for a vast majority of deaths in westernized civilizations. For the development of new treatment strategies, it is important to have a detailed picture of LDL nanoparticles on a molecular basis. Through

Om normer

Hur vet vi vad som är rätt och fel i en situation? Och hur avgör vi hur vi ska handla? Lagar är tydligt nedskrivna och det finns föreskrivna sanktioner om man bryter mot lagen. Men så tydligt är inte vårt samhälle. När vi är laglydiga utan att känna till lagen följer vi egentligen normer. Vårt handlande styrs sällan enbart av lagar och regler utan av dessa, oskrivna och osynliga, normer.Normer och

Studies of Ligands and Receptors Regulating Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is the most common leukemia in adults and is coupled to a poor prognosis, with a five-year overall survival of around 20% and a high risk of relapse. In AML, immature myeloid cells accumulate rapidly in the bone marrow impairing normal blood cell development. Current treatments fail to eradicate the leukemia stem cells, which is a self-renewing population of leukemia c

Common Breaks in Means for Cross-Correlated Fixed-T Panel Data

This note considers a panel data model in which the variable of interest has undergone a common structural break in the mean. The object of interest is the unknown breakpoint. The challenge is to device an estimator that is consistent when the data are cross‐correlated and the number of time periods T is fixed and cannot be increased without bound. The proposed solution involves taking an already

Plasmodium falciparum : a simplified technique for obtaining singly infected erythrocytes

We report the development of a simple technique involving 15 ml polypropylene tubes and a rotatory incubator for obtaining erythrocytes singly infected with Plasmodium falciparum. This technique will be useful for cloning of the parasite. Our finding that P. falciparum merozoite invasion is inhibited during rotation suggests that this method may also be useful for the study of parasite-erythrocyte

Altered aromatic amine metabolism in epileptic patients treated with phenobarbital

The fate of carcinogens differs among individuals who have different activities of drug-metabolizing enzymes that are important in activating and detoxifying carcinogens. A drug that profoundly alters the metabolism of the drugs and carcinogens is the anticonvulsive agent phenobarbital. To investigate why epileptic patients appear to have a low risk of cancer of the urinary bladder, and on the bas

Greater tau load and reduced cortical thickness in APOE ε4-negative Alzheimer’s disease : a cohort study

Background: Alzheimer’s disease is characterized by aggregated β-amyloid and tau proteins, but the clinical presentations and patterns of brain atrophy vary substantially. A part of this heterogeneity may be linked to the risk allele APOE ε4. The spread of tau pathology is related to atrophy and cognitive decline, but little data exist on the effects of APOE ε4 on tau. The objective of this prelim

Detector rates for the Small Angle Neutron Scattering instruments at the European Spallation Source

Building the European Spallation Source (ESS), the most powerful neutron source in the world, requires significant technological advances at most fronts of instrument component design. Detectors are not an exception. The existing implementations at current neutron scattering facilities are at their performance limits and sometimes barely cover the scientific needs. At full operation the ESS will y

Linking developmental diet to adult foraging choice in Drosophila melanogaster

Rather than maximizing intake of available macronutrients, insects increase intake of some nutrients and restrict intake of others. This selective consumption influences, and potentially optimizes, developmental time, reproduction and lifespan of the organism. Studies so far have focused on discriminating between protein and carbohydrate uptake and the consequences on fitness components at differe

Increased Hepatic PDGF-AA Signaling Mediates Liver Insulin Resistance in Obesity-Associated Type 2 Diabetes

In type 2 diabetes (T2D), hepatic insulin resistance is strongly associated with nonalcoholic fatty liver disease (NAFLD). In this study, we hypothesized that the DNA methylome of livers from patients with T2D compared with livers of individuals with normal plasma glucose levels can unveil some mechanism of hepatic insulin resistance that could link to NAFLD. Using DNA methylome and transcriptome

Skånes Väl. De skånska regionalisternas möte med de svenska nationalisterna

“Skånes väl”. The scanian regionalists meet the Swedish nationalists. During the past two decades right-wing populist parties have made substantial electoral gains in many West European countries. In Sweden the success of such parties has been limited compared to e.g. Denmark and Norway. In 1998 an electoral coalition of local populist parties, ";Skånes Väl";, in southern Sweden gained 4.1% of the

Solvent Orange 60 is a potent contact sensitizer in occupational and everyday life

Background: Solvent Orange (SO) 60 is a perinone-type dye that is often used in plastic materials such as spectacle frames and has been shown to cause contact allergy. The first case of SO 60 allergic contact dermatitis caused by spectacle frames was reported in 1999, and the second in 2011. We have recently seen 10 patients, of whom 6 developed dermatitis in the retroauricular/temporal area after

Evaluation of Drug Exposure and Metabolism in Locust and Zebrafish Brains Using Mass Spectrometry Imaging

Studying how and where drugs are metabolized in the brain is challenging. In an entire organism, peripheral metabolism produces many of the same metabolites as those in the brain, and many of these metabolites can cross the blood-brain barrier from the periphery, thus making the relative contributions of hepatic and brain metabolism difficult to study in vivo. In addition, drugs and metabolites co
