Previous studies have shown that biofilms exhibit enhanced resistance to iodine. Investigations were conducted to determine the relative importance of growth phase versus cell density on biofilm resistance of Pseudomonas aeruginosa (ATCC 27853) to iodine. Cell density is a contributing factor to resistance, whereas growth to the stationary phase is not sufficient to achieve resistance.
The purpose was to test the effect of eccentric strength training and flexibility training on the incidence of hamstring strains in soccer. Hamstring strains and player exposure were registered prospectively during four consecutive soccer seasons (1999-2002) for 17-30 elite soccer teams from Iceland and Norway. The first two seasons were used as baseline, while intervention programs consisting ...
BACKGROUND AND OBJECTIVES A 1-year multicenter prospective randomized controlled study was conducted on the effects of vitamin E-bonded polysulfone dialyzers on erythropoiesis-stimulating agent response in hemodialysis patients. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Major inclusion criteria were use of high-flux polysulfone dialyzers with 50-70 ml/min β2-microglobulin clearance over 3...
A cost or resistance surface is a representation of a landscape's permeability to animal movement or gene flow and is a tool for measuring functional connectivity in landscape ecology and genetics studies. Parameterizing cost surfaces by assigning weights to different landscape elements has been challenging however, because true costs are rarely known; thus, expert opinion is often used to deri...
Although early natural menopause has been postulated to increase stroke risk, studies have not produced convincing results. We examined the associations between stroke risks and age at natural menopause or time since natural menopause. 5,731 naturally postmenopausal women more than 65 yr of age were followed from 1993 to 1998. Information on age at menopause and risk factors were obtained using...
BACKGROUND AND PURPOSE Few studies have assessed post-glucose load measures of insulin resistance and ischemic stroke risk, and data are sparse for older adults. We investigated whether fasting and post-glucose load measures of insulin resistance were related to incident ischemic stroke in nondiabetic, older adults. METHODS Participants were men and women in the Cardiovascular Health Study, a...
OBJECTIVE Epidemiological studies suggest that high body iron stores are associated with insulin resistance and type 2 diabetes. The aim of this study was to evaluate the association between dietary intake of iron and the risk of type 2 diabetes. RESEARCH DESIGN AND METHODS We conducted a prospective cohort study within the Nurses' Health Study. We followed 85,031 healthy women aged 34-59 yea...
