Normal cervical changes in parous women during the second half of pregnancy--a prospective, longitudinal ultrasound study.

OBJECTIVE: To determine what constitutes normal cervical changes during the second half of pregnancy in parous women delivering at term. DESIGN: The study comprises 21 healthy, pregnant parous women who all gave birth at term. They were examined with transvaginal ultrasound every two weeks from 24 gestational weeks until delivery. Cervical length and width were measured. The inner cervical os was

Radiological diagnosis of acute stroke. Comparison of conventional MR imaging, echo-planar diffusion-weighted imaging, and spin-echo diffusion-weighted imaging

PURPOSE: To compare conventional MR imaging, echo-planar diffusion-weighted imaging (EP-DWI) and spin-echo diffusion-weighted imaging (SE)-DWI at radiological diagnosis of acute stroke. MATERIAL AND METHODS: Twenty-seven patients (30-85 years old) were examined. Clinical examination was performed before MR imaging. All MR examinations were assessed by an experienced neuroradiologist blinded to cli

Effective treatment of experimental acute otitis media by application of volatile fluids into the ear canal

Essential oils are volatile and can have good antimicrobial activity. We compared the effects of oil of basil ( Ocimum basilicum) and essential oil components ( thymol, carvacrol, and salicylaldehyde) to those of a placebo when placed in the ear canal of rats with experimental acute otitis media caused by pneumococci or Haemophilus influenzae. Progress was monitored by otomicroscopic examination a

Beam modeling and verification of a photon beam multisource model

Dose calculations for treatment planning of photon beam radiotherapy require a model of the beam to drive the dose calculation models. The beam shaping process involves scattering and filtering that yield radiation components which vary with collimator settings. The necessity to model these components has motivated the development of multisource beam models. We describe and evaluate clinical photo

Institutionalisation of sustainable consumption patterns based on shared use

The product-service system (PSS) concept has been proposed as a way of dealing with unsustainable patterns of consumption in the business-to-consumer (B2C) domain. Existing alternatives to traditional consumption based on ownership, such as car sharing, communal washing centres and tool sharing schemes, indicate that more sustainable patterns of consumption may be found for other household functio

Consumption of both resistant starch and beta-glucan improves postprandial plasma glucose and insulin in women

OBJECTIVE - Consumption of a meal high in resistant starch or soluble fiber (P-glucan) decreases peak insulin and glucose concentrations and areas under the curve (AUCs). The objective was to determine whether the effects of soluble fiber and resistant starch on glycemic variables are additive. RESEARCH DESIGN AND METHODS - Ten normal-weight (43.5 years of age, BMI 22.0 kg/m(2)) and 10 overweight

Inhibition of lipase activity and lipolysis in rat islets reduces insulin secretion.

Lipids may serve as coupling factors in KATP-independent glucose sensing in β-cells. We have previously demonstrated that β-cells harbor lipase activities, one of which is the hormone-sensitive lipase. Whether β-cell lipases are critical for glucose-stimulated insulin secretion (GSIS) by providing lipid-derived signals from endogenous lipids is unknown. Therefore, using a lipase inhibitor (orlista

From megaplants to mini-mills - a trend in steelmaking - a prospect for papermaking

A comparison is made between the development trends experience over the last decades by the steel and papermaking industries, respectively. These two industrial branches, although totally different in their technical nature, are subject to similar pressures from their external environment, notably increasing requirements for environmental protection and more efficient raw material management. Such

Risk factor exposure among hepatitis C virus RNA positive Swedish blood donors--the role of parenteral and sexual transmission

The potential modes of transmission for hepatitis C virus (HCV) infections were studied using a multivariate analysis of risk factor exposure among 51 2nd generation anti-HCV and HCV-RNA positive and matched anti-HCV negative blood donors. The following variables were found to be independently associated with anti-HCV and HCV-RNA positivity: intravenous drug use (IVDU) (p < 0.001), blood transfusi

Ligand-induced recruitment of Na+/H+-exchanger regulatory factor to the PDGF (platelet-derived growth factor) receptor regulates actin cytoskeleton reorganization by PDGF.

Proteins interacting with the human PDGF (platelet-derived growth factor) b-receptor were isolated using immobilized peptides derived from the receptor C-terminus as a bait. We identified two PDZ domain proteins, namely NHERF (Na+/H+ exchanger regulatory factor, also called EBP50) and NHERF2 (E3KARP, SIP-1, TKA-1), which have been shown previously to associate with the murine PDGF receptor [Maudsl

Diterpenoids from Coprinus heptemerus

Seven diterpenoids, isolated due to their ability to inhibit spore germination in the plant pathogenic fungus Magnaporthe grisea, were obtained from cultures of the basidiomycete Coprinus heptenlerus. The structures of the compounds, named heptemerones A-G, were determined with spectroscopic techniques. (c) 2005 Elsevier Ltd. All rights reserved.

Macroeconometric Studies of Private Consumption, Government Debt and Real Exchange Rates

Popular Abstract in Swedish Avhandlingen består av fem fristående uppsatser som utnyttjar tidsserieanalys för studerande av några olika makroekonomiska frågor. I kapitel två, tre och fyra används s.k. vektorautoregressiva (VAR) modeller för att studera privat konsumtionsbeteende i Sverige. Enligt den permanenta inkomst hypotesen väljer individerna sin konsumtion med hänsyn till sin långsiktiga ellAdvances in time series analysis during the last two decades have stimulated research in a number of areas in macroeconomics. This thesis is a compilation of five essays using cointegrated vector autoregressive (VAR) models, unit root tests and regime switching models to investigate the behavior of private consumption, public debt and the real exchange rate. Chapter two explores the empirical evi

Revascularization of ischemic tissues by PDGF-CC via effects on endothelial cells and their progenitors

The angiogenic mechanism and therapeutic potential of PDGF-CC, a recently discovered member of the VEGF/PDGF superfamily, remain incompletely characterized. Here we report that PDGF-CC mobilized endothelial progenitor cells in ischemic conditions; induced differentiation of bone marrow cells into ECs; and stimulated migration of ECs. Furthermore, PDGF-CC induced the differentiation of bone marrow
