Rapporten behandlar politiska åtgärder för att miljöanpassa batterier, så att läckage av bland annat kvicksilver och kadmium till naturen kan förhindras. Olika typer av styrmedel såsom lagstiftning, frivilliga åtaganden från branschen, ekonomiska åtgärder och informationskampanjer analyseras med avseende på hur effektiva de varit samt vilka problem och hinder som funnits för att uppnå de formulera

Arctic soil carbon (C) stocks are threatened by the rapidly advancing global warming. In addition to temperature, increasing amounts of leaf litter fall following from the expansion of deciduous shrubs and trees in northern ecosystems may alter biogeochemical cycling of C and nutrients. Our aim was to assess how factorial warming and litter addition in a long-term field experiment on a subarctic h

OBJECTIVE: To compare the antiemetic effect of acupressure at the Neiguan point (P6) in a group of healthy women with normal pregnancy and nausea and vomiting during pregnancy (NVP) with a similar group receiving acupressure at a placebo point and another, similar group not receiving any treatment. STUDY DESIGN: A randomized, placebo-controlled, pilot study involving 60 women. RESULTS: It is possi

Randomized, double-blind, controlled studies have shown that treatment with risedronate reduces the risk of vertebral fracture in postmenopausal women with established vertebral osteoporosis. They also show that the drug decreases the risk of non-vertebral fractures in women with osteoporosis. The aim of this study was to investigate the cost-effectiveness of risedronate in postmenopausal women wi

Histologic grade, including tubular formations, nuclear grade, and mitotic activity, is a well-documented prognostic factor in breast cancer. In comparison with other prognostic parameters, the evaluation of histologic grade is cheap and can be performed, in principle, in all cases of breast cancer. One possible disadvantage is that the evaluation may vary between different pathological department

Phosphodiesterase 3B (PDE3B), is known to play an important role in acute insulin and cAMP-mediated regulation of lipid metabolism, and PDE4 are the main PDE types expressed in adipocytes. Here, we show that members of all PDE4 isoforms are expressed in 3T3-L1 and primary mouse adipocytes. Long-term treatment of 3T3-L1 adipocytes with insulin induced up-regulation of PDE3B and PDE4D in a phosphati

Exposed limestone cliffs in the Swiss Jura Mountains harbour a diverse lichen community with some rare species. Sport climbing has recently increased in popularity on these cliffs. We examined the effect of sport climbing on calcicolous lichens by assessing species diversity and cover of lichens in climbed and unclimbed areas of 10 isolated cliffs in the northern Swiss Jura Mountains. We also inve

Objective-To examine whether DNA microarray analysis of chromosomal susceptibility regions for allergy can help to identify candidate genes. Material and Methods-Nasal biopsies were obtained from 23 patients with allergic rhinitis and 12 healthy controls. RNA was extracted from the biopsies and pooled into three patient and three control pools. These were then analysed in duplicate with DNA microa

Helicobacter pylori exists in two different morphological forms, spiral and coccoid. This study demonstrated that both forms can infect BALB/c A mice. The animals were inoculated orally three times at 2-day intervals with 10(8) cfu of both spiral and coccoid forms of strain CCUG 17874 (NCTC 11637), strain 25 and strain 553/93. Infection was followed over a 30-week period by histological scoring of

Background. The objectives of this report are to evaluate changes in the preterm birth rate in Sweden 1973-2001. Furthermore, describe the proportion of spontaneous and indicated preterm births and assess risk factors for the subgroups of preterm birth during the period from 1991 to 2001. Methods. A population-based register study of all births occurring in Sweden from 1973 to 2001 registered in t

Background: Although patients with multiple sclerosis (MS) are advised to stop interferon (IFN) beta-1a therapy before becoming pregnant, some patients become pregnant while on treatment. Methods: We examined individual patient data from eight clinical trials with IFN beta-1a. Results: Of 3,361 women in the studies, 69 pregnancies were reported, of which 41 were patients receiving (or who had stop

We present a method for the classification of all weak travelling-wave solutions for some dispersive nonlinear wave equations. When applied to the Camassa-Holm or the Degasperis-Procesi equation, the approach shows the existence of not only smooth, peaked and cusped travelling-wave solutions, but also more exotic solutions with fractal-like wave profiles.
