Bacterial endotoxins (BEs) are integrated part of Escherichia coli, a microorganism widely used for the production of recombinant proteins. BEs should be eliminated in the course of down stream processing of target protein produced by these bacteria. Supermacroporous monolith (continuous bed) columns, so called cryogel columns, with immobilized polyethyleneimine (PEI), polymyxin B (PMB) and lysozy
OBJECTIVES: The aim of this study was to identify clinical characteristics of depression in elderly people that could be useful for case finding in general practice. DESIGN: A cross-sectional study of clinical characteristics through review of medical records. SETTING: Herrhagen health centre, Karlstad, Sweden. SUBJECTS: Seventy-one persons with a high depressive score in a screening of depressive
It is widely recognized that there is a discrepancy between principle and practice with respect to the health equity aim of public policy. This discrepancy is analyzed from two theoretical perspectives: the individualization of society and the fact that individual beliefs and values are connected to one’s position in the social structure. These mechanisms influence both the choice of health policy
An acceleration in the rate at which new aquaporin structures are determined means that structural models are now available for mammalian AQP0, AQP1, AQP2 and AQP4, bacterial GlpF, AqpM and AQPZ, and the plant SoPIP2;1. With an apparent consensus emerging concerning the mechanism of selective water transport and proton extrusion, emphasis has shifted towards the issues of substrate selectivity and
The linkages between climate change and sustainable development are multiple and profound. Nonetheless, their respective policy regimes have so far evolved along parallel, if not competing, paths. What is lacking to date is a detailed conceptual understanding of the practicability of their integration through cross-sectoral policies and programmes. We propose a synergistic adaptive capacity (SAC)
This article investigates three hypotheses suggested in the literature on women's political empowerment, operationalized here as increased legislative representation. These hypotheses are that (1) electoral systems manipulate women's political empowerment; (2) increased popular participation empowers women in particular; and (3) accumulated experience gained over several electoral cycles facilitat

This is a review discussing the production and properties of cryogels (from the Greek κριoσ (kryos) meaning frost or ice), immobilization of ligands in cryogels and the application of affinity cryogels in bioseparation. Cryotropic gel formation proceeds in a non-frozen liquid microphase existing in the macroscopically frozen sample. Due to the cryoconcentration of gel precursors in the non-frozen
The M protein family of molecules in the group A streptococcus comprises a number of cell surface proteins that interact with the immune system of the host. One of the proteins in this family is the IgA receptor Arp4, which has C repeats similar to those that characterize the known M proteins. The streptococcal strain expressing Arp4 also expresses a second immunoglobulin-binding protein, Mrp4, wh
Background & Aims: Gastrin deficiency and proton pump inhibitor treatment cause achlorhydria, which predisposes to disease. To elucidate the underlying molecular biology, we examined the changes in gastric gene expression in both types of achlorhydria. We also explored the associated changes in the gastric microflora and the long-term consequences of gastrin-deficient achlorhydria. Methods: Ex
We show that the difference in the infrared vibrational spectrum of C-H stretch modes arising from the methyl group of two surface intermediates, methylthiolate and methoxy, originates from the difference in the methyl deformation modes frequencies of the two intermediates. Importantly, while the vibrational fingerprint of the two methyl groups are not transferable between the intermediates, the F
The Euro50 is a proposed 50m extremely large telescope for optical and infrared wavelengths. To study and predict the performance of the complete telescope system, an integrated model combining the structural model of the telescope, optics models, the control systems and the adaptive optics has been established. Wind and atmospheric disturbances are also included in the model. The model is written
BACKGROUND/AIMS: This study aimed to determine whether deficiency of the major serine protease inhibitors (alpha1-antitrypsin (AAT) or alpha1-antichymotrypsin (ACT)) is associated with increased risk for chronic hepatitis B or C virus (HBV or HCV) infection. METHODS: We studied 709 adults with chronic liver disease who had undergone liver biopsy during the 14-year period 1978-92. Anti-HCV testing
One interpretation of the model considered in this paper is a single-echelon inventory system consisting of a number of local warehouses, which normally replenish from an outside supplier. In case of a stockout at a warehouse an emergency lateral transshipment from another warehouse may be possible. However, such transshipments are only allowed in one direction, i.e., the flow structure is unidire
Serum concentrations of CB-153 and pp'-DDE were assessed for 354 men and women from the Swedish Fishermen's Families Cohort, and were found to correlate very well (Pearson's r = 0.72). In this particular cohort the main source of exposure to persistent organochlorine compounds are consumption of contaminated fatty fish. High correlations between total PCB/CB-153 and p,p'-DDE have also been found i
