Is the relationship between body length and body mass consistent across habitats? A case study on Niphargus (Crustacea: Amphipoda).

Body size is one of the main characteristics of any organism and influences various aspects of individual's biology. In animal ecology, it represents a key functional trait that can be quantified using different measures and is often used as a proxy for different organismal functions. The way we quantify body size is critical in any study using this measure alone or to scale other organismal traits.

Website to promote early detection of breast cancer: "www.thinkhealth.com".

We developed and studied a Website to promote breast cancer screening and allow women to access personalized risk and screening information. The site also provides a database of risk and screening information with multimedia enhancement, and direct interaction with experts and online communities. The site was studied to measure its effectiveness in motivating screening intentions and behaviors among a group of women subjects.

Total calculus removal: an attainable objective?

The primary purpose of this study was to determine if two sessions of scaling and root planing, one using a "closed" approach and the other using an "open" approach, would remove all calculus from teeth with severe periodontal disease. Fourteen teeth (8 single-rooted, 6 multi-rooted) were treated by closed scaling and root planing with an ultrasonic instrument, and 17 others (10 single-rooted, 7 multi-rooted) were treated with hand instruments. After a healing period of 4 to 8 weeks, anesthesia was secured, periodontal flaps were raised, and the teeth were treated a second time using the same instrumentation as before.

Suggested solutions for common problems in clinical periodontics.

This short report offers solutions for three common clinical problems. Based on their experience, the authors suggest using a "spoon" type partial denture for the temporary replacement of maxillary anterior teeth. The denture is unique in that it has no clasps and does not contact the marginal gingiva.

Adrenal defect in adrenomyelodystrophy.

Adrenomyelodystrophy (AMD), a variant of adrenoleukodystrophy, is associated with both neurologic and adrenal dysfunction. Data from an endocrinologic evaluation of a 41-year-old pigmented white man with AMD showed elevation in basal plasma ACTH, 11-deoxycortisol, 17-alpha OH-progesterone and progesterone concentrations, and low normal plasma cortisol levels. Free urinary cortisol and 17-ketosteroid secretion values were within normal limits.
