A time-related deterioration in male reproductive function caused by exposure to endocrine disrupters, including persistent organochlorines (POCs), has been hypothesized. In animal studies, POCs were found to have adverse effects on male reproductive function. However, little is known about the impact of POC exposure on reproductive parameters in men. In a study of 305 young Swedish men 18-21 year

PURPOSE. Cystatin C is a mammalian cysteine protease inhibitor, synthesized in various amounts by many kinds of cells and appearing in most body fluids. There are reports that it may be synthesized in the mammalian retina and that a cysteine protease inhibitor may influence the degradation of photoreceptor outer segment proteins. In the current study cystatin C was identified, quantitated, and loc

Patients with a previous history of anaphylactic reactions to ionic iodinated contrast media were desensitised before a second radiologic examination was performed. The tolerance to the contrast medium was raised by repeated intravenous injections in increasing doses and concentrations. No serious side effects were noted when the examinations with contrast medium was repeated within a few days aft

Extracts of the seeds of Aframomum sulcatum (Oliv. & Hanb) K. Schum (Zingiberaceae) yielded a novel norbislabdane derivative, sulcanal (1) and the new labdane (12E)-8beta,17-epoxy-11-hydroxy-12-labden-15.16-dial-11,15-hemiacetal (2) (as a 1:1 C-15 epimeric mixture), along with known labdane diterpenes.

Popular Abstract in Swedish Organiskt avfall utgör ett problem men är samtidigt en resurs med dess innehåll av näringsämnen och energi. Ett sätt att ta om hand organiskt avfall är att bryta ned det anaerobt genom s.k. rötning. Det organiska materialet reduceras då samtidigt som biogas produceras. Biogas består till största delen av metan som är energirikt och kan ersätta fossila bränslen vid prodAnaerobic digestion of organic matter results in the production of biogas, which can be used to replace fossil fuels. There is potential for increased biogas production at wastewater treatment plants by digesting urban organic waste either separately or together with the sludge. Biogas production could also be increased by sludge pre-treatment. The objective of this work was to evaluate the poten

This study compared the methods of determining the footwear insulation on human subjects and the thermal foot model. Another purpose was to find out minimal number of measurement points on human foot that is needed for insulation calculation. Bare foot was tested at three ambient temperatures on 6 subjects. Three types of footwear were tested on 2 subjects. The mean insulation for bare foot obtain

In dentistry, allergic contact dermatitis to acrylates and allergic contact urticaria to latex are important occupational hazards. There is a need to identify non-latex gloves which are suitable for dental work but at the same time provide adequate protection against acrylate monomers. In a previous study, a new open-chamber system was used for testing the in vivo protection of 6 different gloves

The cone snail is the only invertebrate system in which the vitamin K-dependent carboxylase (or gamma-carboxylase) and its product gamma-carboxyglutamic acid (Gla) have been identified. It remains the sole source of structural information of invertebrate gamma-carboxylase substrates. Four novel Gla-containing peptides were purified from the venom of Conus textile and characterized using biochemica

The 28-kd plasma protein alpha(1)-microglobulin is found in the blood of mammals and fish in a free, monomeric form and as high-molecular-weight complexes with molecular masses above 200 kd. In this study, iodine 125-labeled free and high-molecular weight rat alpha(1)-microglobulin (a mixture of alpha(1)-microglobulin/alpha(1)-inhibitor-3 and alpha(1)-microglobulin/fibronectin complexes) were inje

This article describes the modeling of ultra-wideband wireless propagation channels, especially for the simulation of personal area networks. The IEEE 802.15.3a standards task group has established a standard channel model to be used for the evaluation of PAN physical layer proposals. We discuss the standard model, the measurements that form its basis, and the possibilities for future improvements

In order to investigate and describe the drying kinetics occurring in a porous material during superheated steam drying, a model was developed based on the fundamental transport equations for mass and heat. The driving forces in the model are gradients of moisture, temperature and pressure. The transport coefficients employed were either measured experimentally or were derived theoretically from t

The NorduGrid is the pioneering Grid project in Scandinavia. The purpose of the project is to create a Grid computing infrastructure in Nordic countries. The cornerstone of the infrastructure adopted at NorduGrid is the Globus toolkit developed at Argonne National Laboratory and University of Southern California. It is, however, missing several important high-level services. With the need to provi

Stora summor omsätts i skol- och barnomsorgen. År 2004 stod barnomsorgen för 13 % och skolan för 32 % av kommunerna bruttokostnader på 375 miljarder kronor (SKL, 2005). Tillsammans är verksamheterna de största kommunala kostnadsposterna, följt av vård och omsorg som förbrukar 40 % av bruttokostnaderna. Naturligtvis blir skolans ekonomistyrning viktig i ett sådant sammanhang. I denna artikel beskri

Intestinal crypt epithelial T84 cells form luminal structures and differentiate to intestinal enterocyte-like cells in response to IMR-90 fibroblast-secreted transforming growth factor-beta when grown within three-dimensional collagen gel. In search of TGF-beta regulated genes involved in this differentiation process, we isolated a TGF-beta downregulated cDNA, human homologue of rat apoptosis anta

Analysis of Emanuel Swedenborg and his conceptual understanding of writing

OBJECTIVES: The purpose of this study was to estimate retrospectively the costs of health care resources used in the Malmö Preventive Project, Sweden and estimate the costs of in-patient care that were avoided because of early intervention. SETTING AND SUBJECTS: A large-scale community intervention programme was conducted from 1974 to 1992 in Malmö, Sweden with the aim of reducing morbidity and mo
