Lipopolysaccharide induces cell death in cultured porcine myenteric neurons.

Enteric bacteria execute, via lipopolysaccharide (LPS), a pathogenic role in intestinal inflammation. The effects of LPS on survival and neurotransmitter expression in cultured porcine myenteric neurons were investigated. Myenteric neurons were isolated and cultured for 6 days in medium, in LPS (100 ng/ml) with or without α-ketoglutarate or the nitric oxide synthase (NOS) inhibitor L-NAME, in α-ke

Effect of button location on driver's visual behaviour and safety perception

Although buttons are a frequently used type of control in car interiors, little research has been undertaken on how the usage of buttons affects the visual behaviour of the driver. In this study, the aim was to analyse the effect of push button location and auditory feedback on drivers' visual time off road and safety perception when driving in a real traffic situation. The effect of six button lo

Investigation of the algT operon sequence in mucoid and non-mucoid Pseudomonas aeruginosa isolates from 115 Scandinavian patients with cystic fibrosis and in 88 in vitro non-mucoid revertants

Pseudomonas aeruginosa is the dominant pathogen causing chronic lung infections in patients with cystic fibrosis (CF). After an initial phase characterized by intermittent colonizations, a chronic infection is established upon conversion of P. aeruginosa from the non-mucoid to the mucoid, alginate-overproducing phenotype. During the chronic infection the isolation of both mucoid and non-mucoid iso

Softwood hemicellulose-degrading enzymes from Aspergillus niger: Purification and properties of a β-mannanase

The enzymes needed for galactomannan hydrolysis, i.e. β-mannanase, α-galactosidase and β-mannosidase, were produced by the filamentous fungus Aspergillus niger. The β-mannanase was purified to electrophoretic homogeneity in three steps using ammonium sulfate precipitation, anion-exchange chromatography and gel filtration. The purified enzyme had an isoelectric point of 3.7 and a molecular mass of

Correlation between an early sexual debut, and reproductive health and behavioral factors: a multinational European study

OBJECTIVE: To investigate whether women who made an early sexual debut differ from those with a later debut regarding genital signs and symptoms. METHODS: The study included women who considered themselves gynecologically healthy and who attended 17 family planning centers in 13 European countries for contraceptive advice. There were 629 women who made their sexual debut at the age of 16 years or

Effective-interaction approach to the many-boson problem

We show that the convergence behavior of the many-body numerical diagonalization scheme for strongly interacting bosons in a trap can be significantly improved by the Lee-Suzuki method adapted from nuclear physics: One can construct an effective interaction that acts in a space much smaller than the original Hilbert space. In particular for short-ranged forces and strong correlations, the method o

Lithostratigraphy of the Late Saalian to Middle Weichselian Skaerumhede Group in Vendsyssel, northern Denmark

The Quaternary sedimentary succession in Vendsyssel, northern Denmark, contains a unique, high-resolution record of the last interglacial and glacial periods. There is still much debate, however, about the timing and ice extent in this southwestern part of the Scandinavian Ice Sheet, particularly during the Middle Weichselian. In this study, a detailed lithostratigraphical subdivision is establish

Survival after initial hospitalisation for heart failure: a multilevel analysis of patients in Swedish acute care hospitals

STUDY OBJECTIVE: Although national variation in short-term prognosis (that is, 30 day mortality) after a patients first hospitalisation for heart failure may depend on individual differences between patients, dissimilarities in hospital practices may also influence prognosis. This study, therefore, sought to disentangle patient determinants from institutional factors that might explain such variat

Nile blue adsorbed onto silica gel modified with niobium oxide for electrocatalytic oxidation of NADH

A study of modified carbon paste electrode employing Nile blue (NB) adsorbed on silica gel modified with niobium oxide (SN) for electrocatalytic oxidation of reduced nicotinamide adenine dinucleotide (NADH) is described. The adsorbed organic dye on SN was used to prepare a modified carbon paste electrode to investigate its electrochemical properties. The formal potential (E-o') of the adsorbed NB

The social life and attitudes of 80 year olds in Iceland and Sweden - A comparison of two city populations

The 80+ Studies are collecting longitudinal data regarding medical, psychological, and sociological aspects of 80-year-old people in Lund, Sweden and Reykjavik, Iceland. Methods and Samples: The research design and instruments were identical at the two cites. The number of participants was 139 and 151 respectively. Results: The Icelandic sample had a lower level of educational attainment, a higher

Families' lived experience one year after a child was diagnosed with type 1 diabetes

Aim. This paper is a report of a study to elucidate families' lived experience of diabetes one year after a child was diagnosed with type 1 diabetes. Background. The incidence of type 1 diabetes is rapidly increasing worldwide, with a shift towards younger age groups. This illness is treated by means of an intensive management regimen that often disrupts the child's usual activities and requires d

Models of compact simple Kantor triple systems defined on a class of structurable algebras of skew-dimension one

Let $(A,^-):={\cal M}(J)$ be the $2 \times 2$-matrix algebra determined by Jordan algebra $J:=H_3(\mathbb{A})$ of hermitian $3 \times 3$-matrices over a real composition algebra $\mathbb{A}$, where $(A,^-)$ is the standard involution on $A$. We show that the triple systems $B_A(x,\overline{y}^\sim,z), x,y,z\in\mathbb{A}$, are models of simple compact Kantor triple systems satisfying the condition

Excited Bands in Fixed CNS Configurations

Exact and approximate quantum numbers of the cranked Nilsson-Strutinsky (CNS) formalism are exploited to calculate excited bands in fixed configurations with the energy of the individual bands minimized with respect to deformation for all spin values. The formalism is illustrated to calculate all bands which appear important in the decay out of the superdeformed band in 59Cu

OARSI recommendations for the management of hip and knee osteoarthritis, part I: critical appraisal of existing treatment guidelines and systematic review of current research evidence

PURPOSE: As a prelude to developing updated, evidence-based, international consensus recommendations for the management of hip and knee osteoarthritis (OA), the Osteoarthritis Research Society International (OARSI) Treatment Guidelines Committee undertook a critical appraisal of published guidelines and a systematic review (SR) of more recent evidence for relevant therapies. METHODS: Sixteen exper
