Increasing prevalence of adenocarcinoma of the oesophagus and gastro-oesophageal junction: A study of the Swedish population between 1970 and 1997

Objective: To see whether there was an increasing incidence of adenocarcinoma of the oesophagus and gastric cardia in the Swedish population. If there is a rising trend and variations in it can be found, could it be explained as a period or cohort phenomenon:? The data were also compared with the incidence of squamous cell carcinoma and gastric cancer with the gastric cardia excluded. Design: Retr

The childhood-onset neuropsychiatric background to adulthood psychopathic traits and personality disorders

Childhood conduct disorder (CD) and adult psychopathic traits according to the Psychopathy Checklist Revised (PCL-R) were the closest psychiatric covariates to repeated violent crimes and aggression among offenders under forensic psychiatric investigation in Sweden. As psychopathy is not included in the present psychiatric diagnostic systems, we compared total and factor PCL-R scores to Axis I dis

Identification and synthesis of new bicyclic acetals from caddisflies (Trichoptera)

As shown by synthesis and enantioselective gas chromatography, males and females of the caddisfly species Potamophylax latipennis and Potamophylax cingulatus produce (1R,3S,5S,7S)-1-ethyl-3,5,7-trimethyl-2,8-dioxabicyclo[3.2.1]octane, while Glyphotaelius pellucidus produces 1,3-diethyl-4,6-dimethyl-2,7-dioxabicyclo[2.2.1]heptane, having either the (1S,3S,4R,6S) or (1R,3R,4S,6S)-configuration. As s

Radiative lifetimes and transition probabilities in TaI

Radiative lifetimes of 14 odd-parity Ta I levels, belonging to the 5d(3)6s6p and 5d(4)6p configurations in the energy range from 30 664 to 45 256 cm(-1). have been measured using the time-resolved laser-induced fluorescence technique. Extensive calculations, taking configuration interactions and corepolarisation effects into account, are able to reproduce in a satisfying way the available experime

High resolution polarization spectroscopy and laser induced fluorescence of CO2 around 2 mu m

High resolution Infrared Polarisation Spectroscopy (IRPS) and Infrared Laser Induced Fluorescence (IRLIF) techniques were used to probe CO2/N-2 binary gas mixture at atmospheric pressure and ambient temperature. The probed CO2 molecules were prepared by laser excitation to an overtone and combination ro-vibrational state (12(0)1, J = 15) of CO2, centred at 4988.6612 cm(-1). IRPS and IRLIF line pro

High-spin structure of N similar or equal to Z nuclei around the A=72 region

High-spin states have been studied in Kr-72 and Br-72 using the Ca-40 + Ca-40 and Ar-36 + Ca-40 reactions at 164 and 145 MeV, respectively. The properties and configurations of the high-spin bands observed have been interpreted using impaired cranked Nilssou-Strutinsky (CNS), and for Kr-72, paired cranked relativistic Hartree-Bogoliubov (CRHB) calculations. In Kr-72 a new band has been identified

Endovaskulär teknik vid aortaaneurysm. Lovande alternativ till öppen kirurgi

The article consists in a presentation of endovascular surgery for abdominal aortic aneurysm repair in 23 cases. Two cases required conversion to open surgery, but the procedure could be completed in the remaining 21 cases, with a current duration of follow-up of up to 30 months. There was early leakage in one case, and late leakage in five cases. Late conversion has been necessary in three instan

Do spermathecal morphology and inter-mating interval influence paternity in the polyandrous beetle Tribolium castaneum?

In polyandrous insects, postcopulatory sexual selection is a pervasive evolutionary force favouring male and female traits that allow control of offspring paternity. Males may influence paternity through adaptations for sperm competition, and females through adaptations facilitating cryptic female choice. Yet, the mechanisms are often complex, involving behaviour, physiology or morphology, and the

Cost-effective treatment of uncomplicated gonorrhoea including co-infection with Chlamydia trachomatis

We evaluated the cost effectiveness of treating uncomplicated gonorrhoea in a theoretical cohort of 1000 adults (nonpregnant women of reproductive age, or men) with either intramuscular ceftriaxone 125 mg or a single oral dose of cefixime 400 mg, ofloxacin 400 mg or ciprofloxacin 500 mg. We assumed that all patients were also empirically treated for uncomplicated chlamydial infection, with either

Desulfurization of Low Sulfur Coal by it Acidianus brierleyi: Effects of Microbial Treatment on the Properties of Coal

The effect of microbial desulfurization of two different low-sulfur coals by the thermophilic archaebacteria Acidianus brierleyi was studied with respect to the following properties of the coal: porosity, surface area, pore diameter, particle size, heating value, proximate and ultimate analyses as well as ash composition. About 35-40 percent of the sulfur was oxidized microbially. The microbial tr

Experiences of non-progressive and augmented labour among nulliparous women: a qualitative interview study in a Grounded Theory approach

BACKGROUND: Non-progressive labour is the most common complication in nulliparas and is primarily treated by augmentation. Augmented labour is often terminated by instrumental delivery. Little qualitative research has addressed experiences of non-progressive and augmented deliveries. The aim of this study was to gain a deeper understanding of the experience of non-progressive and augmented labour
