The risk of seizure recurrence within the first year of life was evaluated in infants with neonatal seizures diagnosed with a combination of clinical signs, amplitude-integrated electroencephalogram (EEG) monitoring, and standard EEG. Fifty eight of 283 (4.5%) neonates in tertiary level neonatal intensive care had seizures. The mortality in the infants with neonatal seizures was 36.2%. In 31 survi
A number of screening procedures are offered by midwives during pregnancy and the number is increasing rapidly. The measurement of nuchal translucency is a fairly new ultrasound method for antenatal screening, primarily for Down syndrome. The results give a better risk calculation than maternal age alone and can mean a decrease in the number of invasive procedures needed to identify this syndrome
The possibilities for implementing a rainwater collection system in Ringdansen, a residential area in Norrkoping, Sweden, have been explored by analysing four scenarios for using rainwater in a dual water supply system to supplement drinking water. A computer model has been generated to quantify the water saving potential of the rainwater collection scheme. The performance of the rainwater system
Signaling mechanisms for stretch-dependent growth and differentiation of vascular smooth muscle were investigated in mechanically loaded rat portal veins in organ culture. Stretch-dependent protein synthesis was found to depend on endogenous release of angiotensin II. Autoradiography after [35S]methionine incorporation revealed stretch-dependent synthesis of several proteins, of which SM22 and act
BACKGROUND: RBCs of the Hy- phenotype have, in the past, been typed as Gy(a+(w)), Hy-, Jo(a-), and RBCs with the Jo(a-) phenotype type Gy(a+), Hy-(w), and Jo(a-). Anti-Hy and anti-Jo(a) are difficult to identify mainly because appropriate reagent R6Cs are poorly characterized. Historically, anti-Jo(a) has not reacted with RBCs with either phenotype. This report describes a case of an anti-Jo(a) th
The influence of the auxotrophic deficiencies of the host strain and expression vector selection on the production of a heterologous protein was investigated. Heterologous xylanase production by two prototrophic S. cerevisiae transformants, containing either a plasmid-based, YEp-type expression system or an integrative, YIp-type expression system, were compared with production by an auxotrophic tr
A technique to estimate fungal growth rates in field samples was tested in soil. The technique is based on the addition of C-14-acetate to a soil slurry and the subsequent uptake and incorporation of the labelled acetate into the fungus specific substance ergosterol by the fungi. The addition of fungal inhibitors decreased acetate incorporation rates, while bacterial inhibitors did not. Fungus-fre
Introduction: Complex production systems as, for instance, those used in health care, in off shore industry, in nuclear power industry or in aviation suffer now and then from severe system breakdowns. Lessons learnt from these often lead to changes in the "system". A more rational approach would be to identify these "system weaknesses" before accidents happen. A new proactive method, DEB analysis,
The molecular mechanism of substrate analogue interaction with Escherichia coli dUTPase was investigated, using the non-hydrolyzable 2'-deoxyuridine 5'-(α,β-imido)triphosphate (α,β-imido-dUTP). Binding of this analogue induces a difference in the far UV circular dichroism (CD) spectrum arguing for a significant change in protein conformation. The spectral shift is strictly Mg2+-dependent, does not
It is generally accepted that mating in flour beetles of the genus Tribolium is mediated by a male-produced aggregation pheromone. The pheromone production site in T. castaneum is believed to be glands on the ventral side of the femur. Behavioural experiments with the confused flour beetle T. confusum were conducted using extracts of beetles and different body parts as well as live beetles to inve
To study the role of serum testosterone (T), estradiol (E(2)), and SHBG as regulators of peak bone mass and bone turnover rate in males, a cross-sectional study with data on lifestyle factors collected retrospectively was performed in 204 young Finnish men, 18.3-20.6 yr old. One hundred fifty-four men were recruits of the Finnish Army, and 50 were men of similar age who had postponed their militar
We study aspects of scattering theory for the Schrödinger operator on the real line. In the first part of the thesis we consider potentials supported by a half-line, and we are interested in the inverse problem of reconstruction of the potential from the knowledge of values of the reflection coefficient at equidistributed points on the positive imaginary axis. Under the assumption of exponential d
The aim of the study was to provide a standardisation of self-reported competencies and emotional/behavioural problems among Swedish adolescents, using the Youth Self-Report (YSR). The YSR was completed by 2522 adolescents aged 13-18 years, recruited from secondary and upper secondary schools in different regions in Sweden. The results showed that effects of gender and age were small but significa
A method for generating controlled atmospheres of hexahydrophthalic anhydride (HHPA) in an 8 m3 exposure chamber was developed. The permeation principle was used for gaseous HHPA generation. HHPA concentration was monitored by sampling on XAD-2 tubes and by a Fourier-transform infrared (FTIR) spectrometer using the partial least-square quantitative method. The repeatability of the FTIR was 5%, the
