    • Objective: Increased testosterone and decreased sex hormone-binding globulin (SHBG) are associated with a number of adverse cardiovascular risk factors in postmenopausal women. The aim of this popula-tion-based study of women aged 25 to 50 was to as-sess the relationship between free androgen index (FAI) and cardiovascular risk factors in premeno-pausal women.Methods: A population-based survey of 396 premenopausal women with no hormonal trea- tment was undertaken as part of the Northern Swe-den MONICA study. The study involved question-naires, anthropometry and assays of testosterone and SHBG.Results: Increased FAI was associated with a number of cardiovascular risk factors in premeno-pausal women but this relationship was strongly af-fected by body mass index (BMI). After adjustment for age and BMI, FAI was significantly associated with increased systolic and diastolic blood pressures.Conclusion: Hyperandrogenism is associated with increased blood pressure and these findings empha-size the need to assess cardiovascular risk factors in women with hyperandrogenism of all ages.

  • In vitro characterization and osteoblast responses to nanostructured photocatalytic TiO2 coated surfaces.
  • 2012
  • Ingår i: Acta Biomaterialia. - : Elsevier BV. - 1878-7568 .- 1742-7061. ; 8:6, s. 2411-6

    • The aims of the study were to characterize a nanostructured photoactive titanium dioxide (TiO(2)) coating and to compare the cellular response of human osteoblasts before and after ultraviolet (UV) irradiation of the coating. A specific nanostructured TiO(2) powder (Degussa P-25), which consists of approximately 80% anatase and 20% rutile, was spin-coated onto commercially pure titanium discs, and was heat-treated thereafter. After topographical, chemical and photocatalytic property characterizations, human osteoblasts were cultured on the coated discs before and after UV irradiation. Cell morphology was evaluated by scanning electron microscopy (SEM), and cell viability was analysed by 3-(4,5-dimethylthiazol)-2,5-diphenyltetrazolium bromide (MTT) assay. From the contact angle analysis, the wettability significantly improved after UV irradiation. The cultured cells were flattened with numerous elongated lammellipodia; however, no morphological differences were indicated between -UV and +UV surfaces. The MTT assay analysis showed that -UV surface presented significantly higher viability compared to the +UV surface except for one cell population group at 3h where there were no differences. The nanostructured photoactive TiO(2) surface improved its hydrophilicity by UV irradiation, however no enhancing effect in cell response was confirmed at the time tested compared to the non-irradiated surface.
