The anti-Müllerian hormone type II receptor: insights into the binding domains recognized by a monoclonal antibody and the natural ligand.

Anti-Müllerian hormone (AMH) [also called Müllerian inhibiting substance (MIS)] is a member of the transforming growth factor-beta family. AMH and its type II receptor (AMHR-II) are involved in the regression of the Müllerian ducts in the male embryo, and in gonadal functions in the adult. AMH is also known to be a marker of granulosa and Sertoli cell tumours.

The design of venous thromboembolism prophylaxis trials: is enoxaparin more effective than fondaparinux?

The aim of thromboprophylaxis is to minimise the incidence of clinically relevant venous thromboembolism (VTE) but in many trials designed to determine the efficacy of thromboprophylactic agents, asymptomatic VTE is included in the primary endpoint. Since asymptomatic events occur much more frequently than symptomatic events, they dominate the results. Data from trials comparing the thromboprophylactic efficacy of enoxaparin and fondaparinux in orthopaedic surgical patients are used to demonstrate that asymptomatic and symptomatic endpoints may yield different conclusions.

Cytokine targeting in tumors using a bispecific antibody directed against carcinoembryonic antigen and tumor necrosis factor alpha.

The use of tumor necrosis factor alpha (TNFalpha) in cancer therapy is limited by its short circulatory half-life and its severe systemic side effects. To overcome these limitations, we evaluated the capability of a bispecific antibody (BAb) directed against carcinoembryonic antigen (CEA) and human TNFalpha to target this cytokine in tumors. A BAb was constructed by coupling the Fab' fragments from an anti-CEA monoclonal antibody (MAb) to the Fab' fragments from an anti-TNFalpha MAb via a stable thioether linkage.
