Investigations on health-related properties of two sepiolite samples.

Published i.p. injection studies have shown different biological behavior of different sepiolite samples. There was no evidence for carcinogenic potential of sepiolite from Vicalvaro, Spain, whereas a high tumor incidence was reported for sepiolite from Finland. The low biological activity of the sepiolite from Vicalvaro, compared to the Finnish sample, could be caused by low in vivo persistenc...

Properties and Applications of Palygorskite-sepiolite Clays

The palygorskite-sepiolite group of clay minerals has a wide range of industrial applications derived mainly from its sorptive, rheological and catalytic properties which are based on the fabric, surface area, porosity, crystal morphology, structure and composition of these minerals. For assessing potential industrial uses, the mineralogical and chemical composition of the clay and its basic ph...

Electrokinetic and adsorption properties of sepiolite modified by 3-aminopropyltriethoxysilane.

Surface modification of clay minerals has become increasingly important for improving the practical applications of clays such as fillers and adsorbents. An investigation was carried out on the surface modification of sepiolite with aminopropylsilyl groups in 3-aminopropyltriethoxysilane (3-APT). The zeta potential of the modified sepiolite suspensions was measured as a function of initial elec...

Matched Samples in Medical Investigations.

In investigating the effects of a treatment or experience on a group of patients, it is usually necessary to observe a control group. The comparison between the two groups may be influenced by the characteristics of the subjects: for example, their sex, age, body weight, and original clinical state.. In order to secure comparability for such relevant "extraneous" factors, the controls are frequ...

Assessment of oral health-related quality of life: Comparison of two measurement tools

BACKGROUND AND AIM: Development of patient-based outcome measures has enhanced our ability to assess the oral health-related quality of life (OHRQoL). Present study aimed to compare the performance of the Geriatric Oral Health Assessment Index (GOHAI) and the Oral Health Impact Profile-14 (OHIP-14) as two methods of assessment of oral health-related quality of life.METHODS: In this cross-sectio...
