Attenuated total reflectance FTIR spectroscopy was used to characterize Al(III)-acetate complexation at 25 degrees C, in homogeneous aqueous solution and at the water-aluminum hydroxide interface. The data collected in aqueous solution, at [Al](tot) = 0.080 M, [OAc](tot) = 0.040 M, and pH < 4.3, indicate the presence of only one dominating complex which, by spectral analysis, is shown not to invol

With only approximately 50 olfactory receptor neurons (ORNs), the carrot psyllid Trioza apicalis (Homoptera: Psylloidea) may have the smallest olfactory system described in adult Neopteran insects. Using single sensillum recordings (SSR) and gas chromatograph-linked SSR, we characterized 4 olfactory sensilla forming a distinct morphological type, which together house approximately 25% of all ORNs.

Objective This study aimed to explore the potential of in vivo q-space imaging in the differentiation between different cerebral water components. Materials and Methods Diffusion-weighted imaging was performed in six directions with 32 equally spaced q values and a maximum b value of 6600 s/mm2. The shape of the signal-attenuation curve and the displacement propagator were examined and compared

This study describes the development of a high throughput procedure for the extraction, purification, and quantification of all 16 polycyclic aromatic hydrocarbons (PAHs) on EPA's priority list, subject to biodegradation assays in a creosote-contaminated soil. We used various combinations of solvents, temperatures, ultrasonication, tumbling, saponification, vacuum centrifugation, adsorption chroma

To compare the effectiveness of individual support, group rehabilitation and a combination of the two in improving health-related quality of life (HRQOL) and psychological well-being in cancer patients during 24 months after diagnosis, as compared with standard care (SC). Furthermore, to compare the study sample and a random sample of the Swedish population with regard to HRQOL. A total of 481 con

In the present study, the turbulent heat transfer and fiction in a square duct roughened by continuous and truncated ribs on one wall has been investigated experimentally. The ribs are oriented transversely to the main stream in a periodic arrangement. For both cases, the rib height-to-hydraulic diameter ratio is 0.15, the rib pitch-to-height ratio is fixed at 12, and the Reynolds number varies fr

Palynological samples from Upper Triassic and Lower Jurassic exposures and borehole sections of the Hoganas and Rya formations (Fm), NW Skane (Sweden), exhibit diverse and generally well-preserved palynomorph assemblages that can be divided into four miospore zones (from bottom to top): (1) the informal "Topmost upper Rhaetian" zone of Lund; (2) the TSI assemblage zone which spans the Triassic-Jur

The brain is the exclusive or almost exclusive site of formation of 24S-hydroxycholesterol and we have shown that the circulating level of 24S-hydroxycholesterol is dependent upon the relation between cerebral production and hepatic clearance. In the present work we determined plasma levels of 24S-hydroxycholesterol in patients with various neurological diseases. Eleven subjects with brain death o

Rheumatoid arthritis (RA) is a chronic inflammatory disease primarily affecting cartilaginous joints but also extra-articular tissues such as the nose and upper respiratory tract. We have investigated extra-articular cartilage involvement in two commonly used animal models for RA, collagen-induced and pristane-induced arthritis, by immunizing rats with different susceptibility to disease (LEW.1 A,

The identity of the enzymes responsible for lipase and cholesterol esterase activities in the small intestinal mucosa is not known. Because hormone-sensitive lipase (HSL) catalyzes the hydrolysis of acylglycerols and cholesteryl esters, we sought to determine whether HSL could be involved. HSL mRNA and protein were detected in all segments of the small intestine by Northern and Western blot analys

This study aims att developing a methodology for investigating the relationship between the fluent and disfluent productions of the Swedish conjunction ATT ‘that’ and the complexity of speech fragments following them. A study of the syntactic structure of the speech fragments following ATT and their relation to the pragmatic structure of the discourse, in particular the fragments’ role as regards

We analyze the ripening process where, in a dispersion of vesicles, amphiphile monomers diffuse between vesicles of different sizes, leading to a change in the size distribution. Since, typically, vesicles are not under tension, the driving force for the process comes from the curvature energy. With the conventional expansion of the curvature energy density, g,, to harmonic order we find that the

Studies focusing on genetic and social influences on maternal adjustment will illumine mother's marriage, parenting, and the development of psychopathology in her children. Recent behavioral genetic research suggests mechanisms by which genetic and social influences determine psychological development and adjustment. First, heritable, personal attributes may influence individuals' relationships wi

Gold and platinum, which often are used for thin film metallization, are not suitable for the measurement of dopamine (DA), since the oxidation product of DA forms a non-conducting polymer on the electrode surface. In this work several thiols were screened for their ability to prevent this polymerization. It was found that mercaptopropionic acid (MPA) decreased the rate of DA polymerization. MPA,

The nucleotide sequences of the variable region genes encoding five different human, high affinity antibodies, specific for the major neutralization determinant (AD-1) expressed by human cytomegalovirus glycoprotein B (gp58/116), have been determined. Three of the five heavy chain variable regions belonged to the small VHV-family, although they combined with a diverse set of light chains (V kappa

BACKGROUND: The Cromer blood group system consists of seven high-incidence and three low-incidence antigens carried on decay-accelerating factor (DAF). This report describes the identification and characterization of a new Cromer high-incidence antigen, named GUTI. STUDY DESIGN AND METHODS: RT-PCR and sequence analysis were performed on cDNA prepared from a Chilean donor whose serum contained the
