In the golden egg bug (Phyllomorpha laciniata Vill. Heteroptera: Coreidae) females lay eggs on the backs of conspecifics, often on courting males. Although the bugs do not provide care to the eggs, this decreases the risk of egg predation. As an effect males carry many eggs which are not their own. The male and female interests are in conflict; females need to find an oviposition site, and male fi

The apolipoprotein (apoE) epsilon4 allele was studied in fronto-temporal dementia (FTD), a diagnostic category including the specific disorders Pick's disease and frontal lobe degeneration of non-Alzheimer type (FLD). These dementing diseases have neuronal and synaptic degeneration in common with Alzheimer's disease (AD), for which the presence of the apoE epsilon4 allele is a known risk factor, a

Morphologic and physiologic changes taking place in carbon-limited submerged cultures of Aspergillus nidulans DeltaflbA and fadA(G203R) strains were studied. Loss-of-function mutation of the flbA gene resulted in an altered germination with unusually thick germination tubes, "fluffy" pellet morphology, as well as a reduced fragmentation rate of hyphae during autolysis. In the fadA(G203R) mutant st

Both native Trametes hirsuta laccase and the same laccase modified with palmytic chains to turn it more hydrophobic were prepared and studied with cyclic voltammetry and Raman spectroscopy. Native laccase immobilized in the monoolein cubic phase was characterized with resonance Raman spectroscopy, which demonstrated that the structure at the "blue" copper site of the protein remained intact. The d

The present multidisciplinary study examined nigrostriatal dopamine and striatal amino acid transmission in the R6/1 line of transgenic Huntington's disease (HD) mice expressing exon 1 of the HD gene with 115 CAG repeats. Although the number of tyrosine hydroxylase-positive neurons was not reduced and nigrostriatal connectivity remained intact in 16-week-old R6/1 mice, the size of tyrosine hydroxy

Calbindin D-28k (calbindin) is a cytoplasmic protein expressed in the central nervous system, which is implied in Ca2+ homeostasis and enzyme regulation. A combination of biochemical methods and mass spectrometry has been used to identify post-translational modifications of human calbindin. The protein was studied at 37 degrees C or 50 degrees C in the presence or absence of Ca2+. One deamidation

We report the successful growth of high quality InAs films directly on Si( 111) by Metal Organic Vapor Phase Epitaxy. A nearly mirror-like and uniform InAs film is obtained at 580 C for a thickness of 2 mu m. We measured a high value of the electron mobility of 5100 cm(2)/Vs at room temperature. The growth is performed using a standard two-step procedure. The influence of the nucleation layer, gro

Background: The adipocyte products, leptin and tumour necrosis factor (TNF)alpha are associated with atherosclerotic diseases and may be factors contributing to the enhanced cardiovascular risk in hypopituitary patients with growth hormone (GH) deficiency. Objective: To investigate whether leptin and TNF alpha are increased in a group of hypopituitary women previously found to have increased cardi

The aim of this study was to investigate the reliability and sensitivity of the Wartenberg pendulum test for quantification of muscle tone in young children with spastic diplegia undergoing selective dorsal rhizotomy (SDR). Fourteen nondisabled children (mean age of 5.5 years, age range 2.3 to 8.8 years, one female and one male in each year) were tested twice. Twenty children with spastic diplegia

The location and functional properties of antigen-specific memory T-cell populations in lymphoid and nonlymphoid compartments following DNA immunization or infection with Salmonella were investigated. Epitope-specific CD8+-T-cell expansion and retention during the memory phase were analyzed for DNA-immunized mice by use of a 5-h peptide restimulation assay. These data revealed that epitope-specifi

Gastrin, released from antral G-cells, plays an important role in the regulation of gastric acid secretion and is trophic for the stomach, The cholecystokinin type 2 (CCK)(2) receptor (previously referred to as CCK-B/gastrin receptors) is expressed in both parietal cells and ECL cells in the oxyntic mucosa of stomach. Gastric phenotypic abnormality has been observed in CCK2 receptor null (gene kno

Highly efficient reversed-phase capillary electrochromatography (CEC) separations (plate numbers up to 700 000/m), with electrospray ionization mass spectrometry detection were achieved utilizing novel dextran-coated polymer nanoparticles as a pseudostationary phase. A continuous full filling (CFF) technique in which nanoparticles are continuously introduced into the capillary was employed for sep

Construction projects attract interest from various stakeholders who express needs and expectations about the project. These are often in conflict with each other and it is unlikely that all of them can be fulfilled. The stakeholder management process involves evaluating the needs and expectations of stakeholders in relation to the main objectives of the project. An important basis for this evalua

Purpose: To use velocity-encoded phase contrast (PC) MRI in assessing the effect of coronary microembolization on longitudinal and radial myocardial strain. Materials and Methods: A combined X-ray and MR system (XMR) was used for selective left anterior descending artery catheterization and microinfarct assessment in swine (n = 6). The embolized area at risk was defined on perfusion MRI followed b

For most animals their foraging environment consists of a patch network. In random environments there are no spatial autocorrelation at all, while in fine-grained systems positive autocorrelations flip to negative ones and back again against distance. With increasing grain size the turnover rate of spatial autocorrelation slows down. Using a cellular automaton with foragers having limited informat

This paper is an attempt to understand how people, in the daily practice of interacting with material culture, created, dealt with and interpreted complex and socially stressful historical processes. A 16th-century timber-framed burgher house, the Reformation and industrialization are the focus of attention. Today the house stands in a museum of cultural history in the south Scandinavian town of L

We present exact algorithms with exponential running times for variants of n-element set cover problems, based on divide-and-conquer and on inclusion-exclusion characterisations. We show that the Exact Satisfiability problem of size 1 with m clauses can be solved in time 2(m)l(O(1)) and polynomial space. The same bounds hold for counting the number of solutions. As a special case, we can count the
