A mandibular advancement device reduces sleep disordered breathing in patients with congestive heart failure

Sleep disordered breathing (SDB) including obstructive and central sleep apnoea/ hypopnoea as well as periodic breathing (PB) is common and is believed to increase risk for mortality in patients with congestive heart failure (CHF). Mandibular advancement device (MAD) has widely been recommended for treatment of obstructive sleep apnoea but the method has never been investigated for treatment of SD

Population-based Swedish studies of outcomes after in vitro fertilisation

Background. Various outcomes have been described during pregnancy and among infants born to women after in vitro fertilisation (IVF) treatments. This mini-review summarises recent population-based Swedish studies about the short- and long-term effects of IVF on the infant and child, and also comments on disturbances of pregnancies and deliveries occurring after IVF. Methods. Data on women who had

Cell-specific processing of chromogranin A in endocrine cells of the rat stomach

The rat stomach is rich in endocrine cells. The acid-producing (oxyntic) mucosa contains ECL cells, A-like cells, and somatostatin (D) cells, and the antrum harbours gastrin (G) cells, enterochromaffin (EC) cells and D cells. Although chromogranin A (CgA) occurs in all these cells, its processing appears to differ from one cell type to another. Eleven antisera generated to different regions of rat

A generic model for MIMO wireless propagation channels in macro- and microcells

This paper derives a generic model for the multiple-input multiple-output (MIMO) wireless channel. The model incorporates important effects, including i) interdependency of directions-of-arrival and directions-of-departure, ii) large delay and angle dispersion by propagation via far clusters, and iii) rank reduction of the transfer function matrix. We propose a geometry-based model that includes t

Interactions between Sulfide Minerals and Alkylxanthate Ions .2. A Vibration Spectroscopic and Atomic-Absorption Spectrophotometric Study of the Interactions between Sphalerite and Copper-Activated Sphalerite, and Ethyl-Decylxanthate and N-Decylxanthate Ions in Aqueous and Acetone Solutions

The reactions between three sphalerite samples and ethyl- and n-decylxanthate ions have been studied in aqueous and acetone solutions. Qualitative analysis of the species present on the sphalerite surfaces before and after treatment with these ions have been performed by means of diffuse reflectance infrared Fourier transform spectroscopy. Atomic absorption spectrophotometry has been used to deter

L22 ribosomal protein and effect of its mutation on ribosome resistance to erythromycin

The ribosomal protein L22 is a core protein of the large ribosomal subunit interacting with all domains of the 23 S rRNA. The triplet Met82-Lys83-Arg84 deletion in L22 from Escherichia coli renders cells resistant to erythromycin which is known as an inhibitor of the nascent peptide chain elongation. The crystal structure of the Thermus thermophilus L22 mutant with equivalent triplet Leu82-Lys83-A

More on the 1/f2 Phase Noise Performance of CMOS Differential-Pair LC-Tank Oscillators

This paper presents a rigorous phase noise analysis in the 1/f2 region for the differential CMOS LC-tank oscillator with both nMOS and pMOS switch pairs. A compact, closed-form phase noise equation is obtained, accounting for the noise contributions from both tank losses and transistors currents, which allows a robust comparison between LC oscillators built with either one or two switch pairs. The

Physical characteristics of young men with cleft lip, with or without cleft palate, and cleft palate only.

We report the weight, stature, body mass index (BMI), and muscular strength of men about 19 years old who have cleft lip, either with or without cleft palate (CLP), or cleft palate only (CP). Data were obtained from the Swedish National Service enrolment register for the years 1991 - 97, and concerned 335 men with CLP and 88 with CP, who were compared with a control group of 272 879 men. The data

The relation between accidents and output in Swedish industry

Traditionally, occupational injury rates are measured as number of injuries per amount of work. In contrast, we propose that for certain purposes of economic policy, a more relevant measure could be obtained by considering them as production costs and comparing them with output. This was accomplished by replacing “hours worked” in the traditional formulae for estimating accident risk with “value a

Prostate specific antigen based biennial screening is sufficient to detect almost all prostate cancers while still curable

PURPOSE: We evaluated whether biennial screening with prostate specific antigen (PSA) only is sufficient to detect prostate cancer while still curable. MATERIALS AND METHODS: In Goteborg, Sweden 9,972 men 50 to 65 years old were randomized to PSA screening. During 1995 and 1996 these men were invited for a first PSA screening and invited during 1997 and 1998 for a second screening. The screening p

How do Swedish paediatric clinics diagnose coeliac disease? Results of a nationwide questionnaire study

Background and aim: Diagnosis of coeliac disease is based on the demonstration of enteropathy in a small bowel biopsy. Correct diagnosis is of utmost importance, since the need for dietary management is life long, and inadequate treatment may lead to potentially serious complications. The Swedish Working Group for Paediatric Coeliac Disease has published guidelines for the diagnosis of childhood c

The role of vascular surgery in chronic leg ulcers: report from a specialized ulcer clinic.

Experience gained from cooperation between dermatologists and vascular surgeons in 177 patients evaluated at a joint leg ulcer clinic is reported. Patients were divided into two subgroups: (i) 86 patients with healed ulcers and (ii) 91 patients with ongoing therapy-resistant ulcers. Venous insufficiency was the most common etiology in both subgroups (87% and 55%, respectively). Of previous therapy
