Fetal and maternal Doppler velocimetry and cytokines in high-risk pregnancy

Objective: Fetal hypoxia and preterm delivery are reported to be strongly associated with brain damage and neurodevelopmental delay. Doppler signs of fetal brain sparing have been described during chronic hypoxia, but whether they are related to brain damage is unknown. The aim of this study was to evaluate if markers of tissue injury, i.e., tumor necrosis factor-alpha. (TNF-alpha) and interleukin

Quantitative measurements of species and temperature in a DME-air counterflow diffusion flame using laser diagnostic methods

A diffusion flame of dimethyl ether (DME) and air in a counterflow burner has been investigated experimentally by means of different laser-based methods. Quantitative measurements of temperature, O-2 concentration, and OH concentration have been carried out using dual broadband rotational coherent anti-Stokes Raman Spectroscopy (CARS), Rayleigh scattering and laser-induced fluorescence (LIF). Furt

Plasma Osteocalcin Is Inversely Related to Fat Mass and Plasma Glucose in Elderly Swedish Men

The osteoblast-derived protein osteocalcin has recently been shown to affect adiposity and glucose homeostasis in mice, suggesting that the skeleton influences energy metabolism through an endocrine mechanism. The aim of this study was to investigate the relationship between plasma osteocalcin and parameters reflecting fat mass and glucose homeostasis in humans. Fasting levels of plasma osteocalci

The effect of crystallinity on strength development of alpha-TCP bone substitutes.

Alpha phase tricalcium phosphates (alpha-TCP) were produced using a solid-state reaction method and milled for various periods of time. The resulting four materials were alpha-TCPs, ranging in crystalline content. Powders were exposed to X-ray diffraction for material identification as well as for use in crystallinity and purity calculations. Powder particle size was investigated using laser diffr

Astrophysical laser operating in the OI 8446-angstrom line in the Weigelt blobs of eta Carinae

Within the framework of a simple model of photophysical processes in the Weigelt blobs in the vicinity of the luminous blue variable (LBV) star eta Carinae, we explain the presence of the fluorescent < O I > 8446-angstrom and forbidden [O I] 6300-angstrom lines as well as the absence of the allowed O I 7774-angstrom line in spectra recorded with the Hubble Space Telescope (HST)/STIS instrument (Gu

The association of a SNP upstream of INSIG2 with body mass index is reproduced in several but not all cohorts

A SNP upstream of the INSIG2 gene, rs7566605, was recently found to be associated with obesity as measured by body mass index (BMI) by Herbert and colleagues. The association between increased BMI and homozygosity for the minor allele was first observed in data from a genome-wide association scan of 86,604 SNPs in 923 related individuals from the Framingham Heart Study offspring cohort. The associ

Challenges to medications development in treating alcohol dependence: An international perspective - Summary of a symposium held at the ESBRA Congress, Prague, 13 September 2003

Few medications for treating alcohol dependence exist. Greater partnership is needed between academia and the pharmaceutical industry to develop, licence and market efficacious medications for treating alcohol dependence. Methodologies that span the divide between preclinical and large-scale clinical studies need to be developed in order to provide sufficient information on safety, toleration, dru

Mechanisms behind postspinal headache and brain stem compression following lumbar dural puncture - a physiological approach.

Background: The cause of postspinal headache and its specific characteristics are unknown, and whether lumbar dural puncture (LP) triggers brain-stem compression in patients with brain oedema is still controversial. Methods: Hydrostatic effects of distal opening of the dural sac towards the atmosphere are described and applied to the normal brain and the brain with disrupted BBB. Analogue analyse

The attitudes of patients and staff towards aspects of health promotion interventions in mental health services in Sweden

The present study investigates attitudes towards aspects of health promotion in mental health services, as rated by patients and staff. The aim of the study was to investigate similarities and differences in attitudes towards health promotion interventions among patients and staff in mental health services, using a newly developed questionnaire, the Health Promotion Intervention Questionnaire (HPI

Ward atmosphere, client satisfaction, and client motivation in a psychiatric work rehabilitation unit

This study investigated the ward atmosphere of a psychiatric work rehabilitation unit and its relationships to clients' satisfaction with the unit and client motivation, operationalised as proneness to set personal goals for their rehabilitation. The Community-oriented Programs Environment Scale was used and 52 clients participated. Their report of the ward atmosphere was in accordance with recomm

Three-dimensional antennal lobe atlas of the male moth, Agrotis ipsilon: A tool to study structure-function correlation

The glomerular structure of the primary olfactory neuropil has long been thought to play an important role in odour coding. In insects, the number of glomeruli in the antennal lobe is limited in most species to fewer than 100 compared with more than 1,000 in vertebrates, making it possible to identify individual glomeruli. A complete three-dimensional atlas of the glomeruli within the antennal lob

Energetic consequenses of an inducible morphological defence in crucian carp

Crucian carp (Carassius carassius) increases in body depth in response to chemical cues from piscivores and the deeper body constitutes a morphological defence against gape-limited piscivores. In the ®eld, deep-bodied individuals su€er a density-dependent cost when com- peting with shallow-bodied conspeci®cs. Here, we use hydrodynamic theory and swimming respirometry to investigate the proposed me

Mounting evidence for the presence of influenza A virus in the avifauna of the Antarctic region

Penguin blood samples collected at Bird Island, sub-Antarctic South Georgia, and faecal samples taken from penguins at several localities along the Antarctic Peninsula were analysed in order to investigate if influenza A virus is present in penguin populations in the South Atlantic Antarctic region. Serology was performed on the blood samples while the faecal samples were screened by a RT-PCR meth

Increased expression of non-muscle myosin heavy chain-B in connective tissue cells of hypertrophic rat urinary bladder

Expression of the non-muscle myosin heavy chain-B (NM-MHC-B, also denoted as the embryonic smooth muscle myosin heavy chain, SMemb) was examined in rat urinary bladder during growth in response to a partial urinary outflow obstruction. Following obstruction, the weight of the urinary bladder increased more than five-fold within 10 days. Immunohistochemistry with a polyclonal antiserum against the

Integrated protein microchip assay with dual fluorescent- and MALDI read-out

A pore chip protein array (PCPA) concept based on a dual readout configuration, fluorescence imaging, and MALDI-TOF MS has been developed. Highly packed, (>4000 Spots/cm(2)), antibody arrays were dispensed on the porous chip by using a piezo-electric microdispenser. Sandwich assay was made after blocking by addition of a secondary antibody either lgG-FITC-labeled or anti-Ang II. The antigen in the

Stuttering in adults: The acoustic startle response, temperamental traits, and biological factors.

The purpose of this study was to investigate the relation between stuttering and a range of variables of possible relevance, with the main focus on neuromuscular reactivity, and anxiety. The explorative analysis also included temperament, biochemical variables, heredity, preonset lesions, and altered auditory feedback (AAF). An increased level of neuromuscular reactivity in stuttering adults has p

Gender influences beliefs about health and illness in diabetic subjects with severe foot lesions.

Background. No studies have been found regarding beliefs about health and illness in patients with diabetic foot ulcers investigated from a patient perspective. Beliefs might affect self-care and health. Aim. To explore beliefs about health and illness among patients with severe diabetic foot lesions that might affect self-care practice and care-seeking behaviour. Method. The study design was ex
