Vancouver, Canada recently opened a medically supervised safer injecting facility (SIF) in an effort to reduce HIV and overdose risk and public injection drug use. We sought to examine factors associated with syringe sharing among SIF users. SIF users were randomly recruited into a prospective cohort of SIF users known as the Scientific Evaluation of Supervised Injecting (SEOSI) cohort. We exam...

We evaluated the protective effects of soy isoflavones (SIF) against osteoporosis in middle-aged ovariectomized (OVX) mice. SIF (30 mg/kg or 60 mg/kg) or 17beta-estradiol (E(2)) was administered to OVX mice for 4 months after bilateral ovariectomy. We observed the biochemical markers of bone turnover, e.g., alkaline phosphatase (ALP) and tartrate-resistant acid phosphatase (TRAP), in serum. We ...

OBJECTIVE To evaluate the relationship between skin advanced glycation end products (sAGEs) with mean blood glucose (MBG), hemoglobin A(1c) (HbA(1c)), and MBG-independent, between-patient differences in HbA(1c) among children with type 1 diabetes. RESEARCH DESIGN AND METHODS Children aged 5 to 20 years with type 1 diabetes of at least 1 year duration participated. At a clinic visit, sAGE was ...

• Clarification of stress intensity factor superposition under crack closure phenomena. Importance geometry changes by for is demonstrated. Proposal and discussion two alternative residual applied definitions. Discussion face contact modelling calculation in fatigue load cycles. The correlation between (SIF) range growth a powerful tool fail-safe design approaches to lightweight structures. key...

Inspired by the success of the CIF format in making rapid VLSI prototyping available to the naive designer, we are developing SIF, a new Solid Interchange Format for mechanical design. SIF is a terse, human readable ASCII format providing processand resolution-independent ideal shape specification, explicit design intent and topological information; it also addresses issues of precision and tol...

El factor de intensidad esfuerzos (SIF) es un parámetro suficiente para definir el campo al cual está sujeto cuerpo agrietado bajo los lineamientos la mecánica fractura lineal elástica (LEFM). valor del SIF una función esfuerzo aplicado, longitud grieta y geometría general probeta. Existen varios métodos experimentales calcular este esfuerzos, entre que se destaca Wedge Splitting Test (WST). En...

In this study we have analyzed metal-enhanced fluorescence (MEF) effects from different density silver island films (SiFs) and the effects of sample geometry on the observed enhancement of fluorescence (EF). It is shown that silver islands grow exponentially with SiF deposition time (DT<7min), optical density of SiFs almost linearly depends on DT; electrical conductivity is zero. At DT>7 min, s...

The health effects of soy supplementation in (post)menopausal women are still a controversial issue. The aim of the present study was to establish the effect of the soy isoflavones (SIF) present in a commercially available supplement on ovariectomized rats and to investigate whether these rats would provide an adequate model to predict effects of SIF in (post)menopausal women. Two dose levels (...

A closed-form solution is obtained for the problem of a mode-III interfacial edge crack between two bonded semi-infinite dissimilar elastic strips. A general out-of-plane displacement potential for the crack interacting with a screw dislocation or a line force is constructed using conformal mapping technique and existing dislocation solutions. Based on this displacement potential, the stress in...
