Auditory temporal grouping in newborn infants

Adults normally perceive auditory scenes in terms of sound patterns emitted by concurrently active sources. Thus pattern formation is an important process of auditory object perception. The aim of the present study was to determine whether neonates group sounds by repeating pitch patterns. Standard ("S"; p = 80%) and deviant tones ("D", p = 20%) differing only in pitch were delivered either in a r

Formulation and in vitro/in vivo evaluation of combining DNA repair and immune enhancing nutritional supplements

Combining nutritional supplements to achieve synergistic benefit is a common practice in the nutraceutical industry. However, establishing. added health benefit from a combination of natural ingredients is often assumed, untested and without regard to the principle of metabolic competition between the active components. Here, we report on the combination of a cat's claw water extract (C-Med-100, c

Factors controlling large scale variations in methane emissions from wetlands

[1] Global wetlands are, at estimate ranging 115-237 Tg CH4/yr, the largest single atmospheric source of the greenhouse gas methane (CH4). We present a dataset on CH4 flux rates totaling 12 measurement years at sites from Greenland, Iceland, Scandinavia and Siberia. We find that temperature and microbial substrate availability (expressed as the organic acid concentration in peat water) combined ex

Development of Simultaneous Saccharification and Fermentation for Production of Ethanol from Softwood

This thesis deals with the development of simultaneous saccharification and fermentation (SSF) in order to improve the economy of the softwood-to-ethanol process. The effect of process stream recirculation on ethanol production from steam-pretreated softwood based on SSF was investigated for two process cases. In the first case, part of the stillage stream after distillation was recycled and in th

Genomic deletions and precise removal of transposable elements mediated by short identical DNA segments in primates

Insertion of transposable elements is a major cause of genomic expansion in eukaryotes. Less is understood, however, about mechanisms underlying contraction of genomes. In this study, we show that retroelements can, in rare cases, be precisely deleted from primate genomes, most likely via recombination between 10- to 20-bp target site duplications (TSDs) flanking the retroelement. The deleted loci

In vivo effects of prostacyclin on segmental vascular resistances, on myogenic reactivity, and on capillary fluid exchange in cat skeletal muscle

OBJECTIVE: To analyze the local circulatory effects of prostacyclin in skeletal muscle. DESIGN: A prospective experimental study. SETTING: A university laboratory. SUBJECTS: Twelve adult cats. INTERVENTIONS: The study was performed on autoperfused, sympathectomized gastrocnemius muscle. MEASUREMENTS AND MAIN RESULTS: Arterial blood flow, total and segmental vascular resistances (arterial vessels o

Assessment of the carpal tunnel outcome instrument in patients with nerve-compression symptoms

The outcome movement in medicine has encouraged the development of patient-answered questionnaires as measures of well-being. A disease-specific questionnaire for carpal tunnel syndrome (CTS) was introduced by Levine et al. in 1993. We evaluated this questionnaire in 156 consecutive new patients presenting with pain, numbness, or tingling of the upper extremity. Of these, 114 correctly filled out

Pollen analysis, chronology and palaeomagnetism of three Late Weichselian sites in southern Sweden

Popular Abstract in Swedish Pollenanalys, kronologi och paleomagnetism på tre senglaciala lokaler i södra Sverige Senglaciala sjösediment (d.v.s. avsatta under slutet av den senaste istiden) från tre bassänger i södra Sverige, Torreberga i Skåne, Farslycke i Blekinge och Bolmen i Småland, har studerats med avseende på pollensammansättning och paleomagnetism. Åldersbestämning och tidsjämförelser bThree sites, Torreberga in Skåne, Farslycke in Blekinge and Lake Bolmen in Småland, with Late Weichselian lake sediments were studied with respect to pollen analysis and palaeomagnetism. The chronologies are based on pollen stratigraphical correlations, radiocarbon dating and, for two of the sites, on a clay-varve chronology. The stratigraphies were correlated to the GRIP event stratigraphy and th

Retinopathy and nephropathy in insulin-dependent diabetics: an inconsistent relationship?

The association between retinopathy and nephropathy was investigated in a retrospective study of 52 insulin-dependent diabetics with preproliferative or proliferative retinopathy and in 48 patients without or with background retinopathy. The duration of diabetes was 23.2 +/- 1.0 years (mean +/- SEM) and 22.0 +/- 1.2 years in the two groups. Patients in the retinopathy group showed a higher frequen

Simulations of the absorption and fluorescence of indole in aqueous solution and at a nonpolar/polar interface

Theoretical results are presented on the absorption and fluorescence of indole in aqueous solution as well as at the air/water surface. We use a combined quantum chemical statistical mechanical model with explicit solvent. An approximate ab initio complete active space self-consistent field description of the indole molecule is used, coupled to a discrete polarizable water medium. From the bulk si

A simplified computational kernel for trellis-based decoding

A simplified branch metric and add-compare-select (ACS) unit is presented for use in trellis-based decoding architectures. The simplification is based on a complementary property of best feedforward and some systematic feedback encoders. As a result, one adder is saved in every other ACS unit. Furthermore, only half the branch metrics have to be calculated. It is shown that this simplification bec

Recovery and Rehabilitation in Stroke. Stem Cells.

The recent demostration that neurons for transplantation can be generated from stem cells and that the adult brain produces new neurons in response to stroke has raised hope for the development of a stem cell therapy for patients affected with this disorder. In this review we propose a road map to the clinic and describe the different scientific tasks that need to be accomplished to move stem cell

A 50-year perspective of a family with chromosome 14-linked Alzheimer’s disease

A Swedish family with two generations suffering from presenile dementia with an unusually severe Alzheimer encephalopathy was first reported in 1946. The hypothesis that the disease was inherited through a dominant gene is strongly supported by the follow-up 50years later of three additional generations and molecular genetic findings of a novel presenilin-1 gene mutation in the family. The pedigre

Gärning och frälsning hos Ramanuja

Following a brief account of the main events in the life of Rāmānuja according to traditional hagiographical works, the article examines the fundamental exegetical, epistemological, ontological and soteriological positions of this medieval thinker. These views are contrasted mainly with those of the greatly influential Śaṅkara some centuries earlier, particularly with respect to the conflict betwe

A combined quantum chemical statistical mechanical simulation of the hydration of Li+, Na+, F-, and Cl-

The hydration (or solvation) of the lithium, sodium, fluoride, and chloride ions are investigated using a combined quantum chemical statistical mechanical model. Radial distribution functions and the distribution of coordination numbers are reported and compared with other recent studies. An algorithm to investigate the geometry of the first solvation shell is proposed and applied to the four hydr

Business Angels in a Changing Economy: The Case of Sweden

The Swedish business angel market of 2004 is presented and compared to that of 1992 in order to determine the significance of the time factor. The presentation is carried out against the background of the macroeconomic changes that have taken place and how they have affected the informal venture capital market. The empirical findings reveal how the amounts invested have changed, which companies th

Sentential Object Complements in Modern Standard Arabic

Popular Abstract in Swedish Satser i objektsposition i modern standardarabiska. MODERN STANDARDARABISKA Arabiska talas idag av ca 200 miljoner människor från Marocko och Mauretanien i väster till Irak och Oman i öster. De talade varianterna av språket skiljer sig åt ganska mycket, men man har ett gemensamt skriftspråk. Den moderna varianten av skriftspråket kallas ofta modern standardarabiska ocThis dissertation comprises a corpus-based study of the form and function of sentential object complements in Modern Standard Arabic (MSA). The study is motivated by the scarcity of investigations into MSA syntax as opposed to the syntax of Classical Arabic. Complements to three classes of complement-taking predicates (CTPs) ­ manipulation, cognition and utterance ­ are considered. The major part

Long-term effects of intracellular calcium and growth factors on excitation and contraction in smooth muscle

Modulation of vascular smooth muscle cells from a contractile to a synthetic phenotype is thought to be important in the development of the atherosclerotic lesion. Such modulation depends on growth factors and is influenced by cell-cell and cell-matrix interactions. Whereas smooth muscle cells in the vessel wall are contractile, dispersed cells in culture rapidly modulate to synthetic phenotype, w
