Fertility patients' views about frozen embryo disposition: results of a multi-institutional U.S. survey.

Objective: To describe fertility patients' preferences for disposition of cryopreserved embryos and determine factors important to these preferences.

Design: Cross-sectional survey conducted between June 2006 and July 2007.

Setting: Nine geographically diverse U.

Image analysis of aggrecan degradation in articular cartilage with formalin-fixed samples.

Many studies in arthritis research require an evaluation of the cellular responses within the joint and the ensuing matrix degradation in articular cartilage. The early histochemical/histological scale of Mankin have opened new approaches to evaluating cartilage structure. Histological methods now include in situ hybridization for cell-specific gene expression and immunohistochemistry for the spatial organization of cartilage proteins and their processed forms.

Knee joint injury and repair modeled by membrane systems.

Tissue reparative processes following tissue injury are modeled by a basic membrane system, dealing only with objects, non-active membranes, and non-deterministic evolution rules. At the biological level, tissue repair is regulated by multiple interactions between cells and macromolecules, the latter acting as signals. Such signals modify cell behavior including proliferation, migration, differentiation, and phagocytosis.

Inducible nitric oxide synthase expression by peritoneal macrophages in endometriosis-associated infertility.

Objective: Determine whether peritoneal macrophages from women with endometriosis-associated infertility express more inducible nitric oxide synthase (NOS2) and produce more NO than fertile controls.

Design: Unblinded clinical study.

Patient(s): Nine infertile women with endometriosis and nine normal fertile women undergoing laparoscopy.
