BACKGROUND AND PURPOSE Literature suggests a small increased risk of ischemic stroke with oral contraception (OC) use. We evaluated the association of stroke and OC use in women on the basis of whether they recalled being advised by a physician not to use OC or to discontinue OC use because of the presence of stroke risk modifiers, and whether such advice resulted in behavioral change. METHOD...

We test the common assumption that organic carbon (OC) storage occurs on sand-sized soil particles only after the OC storage capacity on silt- and clay-sized particles is saturated. Soil samples from a Brookston clay loam in Southwestern Ontario were analysed for the OC concentrations in bulk soil, and on the clay (<2 μm), silt (2-53 μm) and sand (53-2000 μm) particle size fractions. The OC con...

BACKGROUND In recent years, an increasing number of countries have introduced outpatient commitment orders (OC), which imply that patients can be subject to compulsory follow-up and treatment while living in the community. However, few studies on how OC is practised have been published. METHOD Retrospective case register study based on medical files of all patients receiving an OC order in 20...

Culicid larvae were collected in snow-melt pools during the first half of June from 1975-1977 and 1995-1996 in the Abisko Valley, Torne Lapmark, northern Sweden. Twelve species were collected from 102 pools and 81 localities with 7,914 specimens (elevations from 300 to 650 m a.s.l.). Fourteen species are now known from the area. Ten types of larval habitats were classified and ten species were ...

In the boreal region, soil organic carbon (OC) dynamics are strongly governed by the interaction between wildfire and permafrost. Using a combination of field measurements, numerical modeling of soil thermal dynamics, and mass-balance modeling of OC dynamics, we tested the sensitivity of soil OC storage to a suite of individual climate factors (air temperature, soil moisture, and snow depth) an...

The huge amount of waste tires (WTs) have been disposed to surroundings which cause dangerous effect on nature. Owing recycled WTs, the pyrolysis is a good technique dismiss harmful by converting into gas, liquid and solid. present study has two steps liquefaction at batch reactor. Firstly, conversion WTs tire oil (WTO) char. Then WTO were blended with calcium oxide (CaO) or natural zeolite (NZ...

The objective of the present study was to analyze the pattern of oral contraceptive (OC) use in teenagers and to examine the relationship between OC use and other cardiovascular risk factors. The study was conducted in 24 Belgian secondary schools. Most students (1526 adolescents aged 12–17 years) agreed to participate (participation rate: 83.6%). Smoking, physical activity habits, menarche, an...

Background The aim of the study was to observe the changes in blood oxidative stress levels by oral contraceptive (OC) and/or dydrogesterone (DG) treatment. Methods A retrospective cohort of 27 premenopausal women with primary dysmenorrhea consisted of the OC treatment group (N = 17) and the DG treatment group (N = 10) by choice of the initial treatment. The OC group included two subgroups: p...

We tested the efTect oC the addition oC biosolids combined with a native rnycorrhizal inoculum (Arbuscular Mycorrhizal Fungi [AMF]) 00 growth oC a native Australian grass, and 00 trace element stabilization oC sulphidic gold mine tailings. A glasshouse trial was established 00 four substrates: tailings (T); tailings with a layer oC 5 cm topsoil (TS); tailings amended with 100 dry t ha-1 biosoli...

This study investigated if an osteoclastic protein-tyrosine phosphatase (PTP), PTP-oc, plays a role in the functional activity and differentiation of osteoclastic cells by determining the effects of overexpression of wild-type (WT)- or phosphatase-deficient (PD)-PTP-oc on bone resorption activity and differentiation of human promyelomonocytic U-937 cells, which could be induced to differentiate...
