Macroporous monolithic hydrogels (cryogel monoliths; rods 12.5 mm x 7.1 mm diameter) are elastic, sponge-like materials with large (10-100 mu m), interconnected pores. Phenyl- and IMAC-(Me(II)-iminodiacetic acid)-cryogel monoliths were inserted into the open-ended wells of a standard 96-well plate, forming a system of 96 drainage-protected minicolumns, and were used in a parallel assay of hydropho
The co-adsorption of Cd(II) and glyphosate (N-(phosphonomethyl)glycine, PMG) at the manganite (gamma-MnOOH) surface has been studied in the pH range 6-10 at 25 degrees C and with 0.1 M Na(Cl) as ionic medium. Batch adsorption experiments, Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and extended X-ray absorption fine Structure (EXAFS) spectroscopy were use
Objective The aim of this work was to study the histologic and manometric changes in the distal esophagus beyond 2 years following endoscopic sclerotherapy (EST) and/or surgical intervention, and to try to understand the etiological factors associated with these changes. Patients and interventions Forty patients, with an average age of 61.5 years, were studied for 2-12 years following sclerotherap
While prior research has often used psychological characteristics to identify entrepreneurs and entrepreneurial behaviour, little has been done to predict venture performance. This study examines the impact of four entrepreneurial characteristics on venture performance. The findings are mixed with previous research but provide a new insight by exploring the characteristics of entrepreneurs in gene
The Land sensitivity equation is a well-known tool for comparing optical performance between eyes. Despite this, the equation has never been experimentally tested. Here, we present, to our knowledge, the first experimental validation of the equation. We have investigated different insect species active at different intensities, and possessing different types of compound eyes, to compare ratios of
Alterations in calcium metabolism have been associated with cardiovascular risk factors. An altered binding of calcium to plasma proteins and raised levels of parathyroid hormone (PTH) have been described in morbid obesity. In the present study, indices of mineral metabolism were related to obesity (body mass index, BMI) and fat distribution (waist to hip ratio, w/h) in 194 subjects with a wide ra
Thirty-three Lactobacillus strains were tested as adjuncts in a cheese model system. Eighteen strains originated from cheese (nine Lactobacillus spp. and nine Lb. paracasei/casei) and 15 from human intestinal mucosa (11 Lb. rhamnosus; three Lb. paracasei; one Lb. plantarum). Model cheeses weighing 120 g were made of cheese grains from full-scale production of washed curd semi-hard cheese (Herrgard
Comparisons of release rates, duration in the field, and catch efficiency of polyethylene and cotton roll dispensers for the sex pheromones of sawflies (Hymenoptera: Diprionidae) were conducted. The release rates of the neodiprion sertifer(Geoffr.) and Diprion pini (L.) sex pheromones, the acetates of pentadecanol and (2S,3S,7S)-3,7-dimethyl (2S,3R,7R)-3,7-dimethyl--tridecanol from polyethylene di
CD44 is a polymorphic transmembrane glycoprotein that exists as multiple isoforms resulting from alternative splicing and posttranslational modifications. Enhanced expression of CD44 has been correlated to the tumorigenicity and metastatic behavior in different malignant tumors. In contrast, human neuroblastomas exhibit an inverse correlation between CD44 expression and tumor malignancy. To determ
The present communication concerns the potential of current surveillance programs for understanding the epidemiology of sexually transmitted infections. The often limited knowledge or the negligence of such infections both among health providers and in the general population, and the non-existence of laboratory services or poor utilization thereof, for example the lack of sampling material, lack o
Some recent sexual selection models predict that female choice in species without paternal care may function to discriminate among males in order to pass ''good genes'' to offspring. Data quantifying the relationship between female mate choice and reproductive success are scarce. In a Swedish population of pheasants females prefer to mate with long-spurred males. Male viability also correlates wit
Perlecan is a heparan sulfate proteoglycan that is expressed in all basement membranes (BMs), in cartilage, and several other mesenchymal tissues during development. Perlecan binds growth factors and interacts with various extracellular matrix proteins and cell adhesion molecules. Homozygous mice with a null mutation in the perlecan gene exhibit normal formation of BMs. However, BMs deteriorate in
In this essay we discuss effects of growing interdependence and internationalization upon national political institutions. More exactly we address the question of how these processes are reflected in matters handled by the Standing Committees of the Swedish Parliament. Generally speaking, the proportion of international issues has increased continuously during the 1970s and the early 1980s. The in
We calculate the linear chirp rates of high-order harmonics in argon, generated by intense, 810 nm laser pulses, and explore the dependence of the chirp rate on harmonic order, driving laser intensity, and pulse duration. By using a time-frequency representation of the harmonic fields we can identify several different linear chirp contributions. to the plateau harmonics. Our results, which are bas
The aim of this review was to examine studies on nursing in hypertension care to find out the nurse's role and skills. Articles were searched during the period 1966-1997. About 650 abstracts were read, and 148 were selected for examination. Forty-two articles were judged to be relevant for the study. The role of the nurse in programs was described as that of a team member, an educator in nonpharma
Forty-five female outpatients sexually abused in childhood were offered a 2-year phase-divided group therapy. Before and after treatment and at 12 months follow-up, they answered questionnaires designed to elicit responses concerning psychological symptoms (Symptom Checklist; SCL-90) and sense of coherence (SOC). Symptoms for posttraumatic stress disorder (PTSD) were assessed before and after trea
Total ectomycorrhizal infection level and the composition of individual infection types were investigated in young Pinus sylvestris seedlings planted in a mature Scots pine forest in southern Sweden, which was N-fertilized 13 years ago. Total ectomycorrhizal infection frequency, approximately 85%, did not differ between the fertilized and non-fertilized plots, but the infection types differed betw
