In this work we have further characterized the first mitochondrial nucleoside diphosphate kinase (mtNDPK) isolated from plants. The mitochondrial isoform was found to be especially abundant in reproductive and young tissues. Expression of the pea (Pisum sativum L. cv Oregon sugarpod) mtNDPK was not affected by different stress conditions. However, the pea mtNDPK was found to interact with a novel

In this article, we explore marital exogamy ( especially intermarriage between immigrants and natives) among 39 different immigrant groups using cross-sectional registry data for the total immigrant populations in Sweden in 2003. Immigrants who are better educated, who spend a longer time in Sweden before marriage and live outside the bigger cities are more likely to be married to natives. Control

Buprenorphine misuse by injecting drug users was assessed in a survey of 350 needle exchangers, either amphetamine (57%) or heroin users (42%). 89% of heroin users and 24% of amphetamine users reported using buprenorphine at some time during the previous year. Most users reported illicit acquisition. Among illicit users, 87% of heroin users reported intake for withdrawal treatment or self-detoxifi

The spin and orbital moments of Au/Co/Au trilayers grown on a W(110) single crystal substrate have been investigated by means of x-ray magnetic circular dichroism. Our findings suggest that the orbital moment of Co does not obtain a maximum value along the easy axis, in contrast with previous experience. This is attributed to the large spin-orbit interaction within the Au caps. Both second order p

Methods currently used for surface display on insect cells and budded baculovirus, all utilize the sequences from class I transmembrane proteins. This gives rise to some problems when handling unknown genes or cDNAs encoding full-length proteins. First, the stop codon from the cloned gene will be located upstream of the sequence for the transmembrane region. Second, the chance of getting the seque

Exposure to exogenous (oral contraceptives, postmenopausal hormone therapy) and endogenous (number of ovulatory cycles, adiposity) steroid hormones is associated with breast cancer risk. Breast cancer risk associated with these exposures could hypothetically be modified by genes in the steroid hormone synthesis, metabolism and signaling pathways. Estrogen receptors are the first step along the pat

Previous studies on wake flow visualization of live animals using DPIV have typically used low repetition rate lasers and 2D imaging. Repetition rates of around 10 Hz allow similar to 1 image per wingbeat in small birds and bats, and even fewer in insects. To accumulate data representing an entire wingbeat therefore requires the stitching-together of images captured from different wingbeats, and a

The effect of the antimicrobial agent TMPAC (3-(trimethoxysilyl)-propyldimethyloctadecyl ammonium chloride) on the cellulase activity oil model cellulose substrate was investigated by in situ-null ellipsometry. The cellulases used were extracted from Trichoderma virlde and Aspergillus niger, and the model cellulose film was prepared by spin-coating silicon oxide wafers with cellulose solubilized i

Northern forests are exposed to relatively high ammonia inputs due to high atmospheric deposition and the common practise of forest fertilization. It is not known how increased soil NH4 +concentrations affect acquisition of symbiosis-mediated N from organic sources. We examined the effect of inorganic N and P availability on N acquisition from alanine by 43 weeks old birch (Betula pendula) seedlin

Purpose: To compare glaucoma conversion rates in patients with ocular hypertension (OH) with and without pseudoexfoliation. Design: Cohort study, based on 32 918 screening participants. Participants and Controls: Ninety-eight patients with OH and pseudoexfoliation and 98 matched controls. Main Outcome Measure: Perimetric glaucoma conversion. Methods: A population-based glaucoma screening of elderl

BACKGROUND: Mean left atrioventricular plane displacement is strongly related to prognosis in patients with heart failure. We aimed to examine its value for prognostication and risk stratification in patients hospitalised for acute myocardial infarction. METHODS AND RESULTS: Left atrioventricular plane displacement was assessed by echocardiography in 271 consecutive patients with acute myocardial

The human endometrium is a dynamic tissue, which undergoes extensive tissue remodelling during the menstrual cycle. Due to their involvement in such processes, several well-characterized matrix metalloproteinases (MMP) have previously been studied in the endometrium. MMP-26 is a newly described matrilysin. We studied MMP-26 mRNA in 39 normal endometrial samples obtained across the menstrual cycle.

Smart polymers (SP) have become one important class of polymers and their applications have been increasing significantly. Last two to three decades have witnessed explosive growth in the subject. SP which are also known as stimuli-responsive soluble insoluble polymers or environmentally sensitive polymers have been used in the area of biotechnology, medicine and engineering. The present review is

The article presents an analytical model for evaluation of ion angular distribution functions (IADFs) at a radio frequency (rf)-biased surface in a high-density plasma reactor. The model couples a unified rf sheath model to an assumed ion velocity distribution function-based formulation for determining the IADF under any general rf-bias condition. Under direct-current (dc) bias conditions the IADF

The aim of this study was to evaluate the added utility of gadolinium administration in the magnetic resonance imaging evaluation of developmental delay in children less than 2 years of age. A computerized retrospective study identified all brain magnetic resonance imaging examinations using gadolinium performed at our institution from 1995-2002 for children under the age of 2 years. Review of the

We have in a population-based setting evaluated biochemical markers of bone metabolism in 328 women, aged 40-80 years, and related it to contents of bone mineral measurements and the retrospective and prospective presence of fracture. The participants were recruited from the city population files. Serum samples for analysis of osteocalcin (Oc), procollagen I carboxy-terminal extension peptide (PIC

Aims: When analyzing P-wave morphology, the vectorcardiogram(VCG) has been shown useful to identify indicators of propensity to atrial fibrillation (AF). Since VCG is rarely used in the clinical routine, we wanted to investigate if these indicators could be accurately determined in VCG derived from standard 12-lead ECG (dVCG).Methods: ECG and VCG recordings from 21 healthy subjects and 20 patients
