- A new program of Compton scattering on deuterium is under way at the tagged-photon facility at MAX-Lab in Lund, Sweden. We will measure differential cross sections between 60A degrees and 150A degrees over the photon energy range 60-115 MeV in 5 MeV steps, with the ultimate goal of obtaining new precision information on the electric and magnetic polarizabilities of the neutron.

- The two-body photodisintegration of He-3 has been investigated using tagged photons with energies from 14-31 MeV at MAX-lab in Lund, Sweden. The two-body breakup channel was unambiguously identified by the (nonsimultaneous) detection of both protons and deuterons. This approach was made feasible by the overdetermined kinematic situation afforded by the tagged-photon technique. Proton-and deuteron-energy spectra were measured using four silicon surface-barrier detector telescopes located at a laboratory angle of 90 degrees with respect to the incident photon-beam direction. Average statistical and systematic uncertainties of 5.7% and 6.6% in the differential cross section were obtained for 11 photon-energy bins with an average width of 1.2 MeV. The results are compared to previous experimental data measured at comparable photon energies as well as to the results of two recent Faddeev calculations which employ realistic potential models and take into account three-nucleon forces and final-state interactions. Both the accuracy and precision of the present data are improved over those obtained in the previous measurements. The data are in good agreement with most of the previous results, and favor the inclusion of three-nucleon forces in the calculations.

- Assessment of impairment and function is essential in order to monitor joint status and evaluate therapeutic interventions in patients with haemophilia. The improvements in the treatment of haemophilia have required the development of more sensitive tools to detect the more minor dysfunctions that may now be apparent. This paper outlines some of the recent developments in this field. The Haemophilia Joint Health Score (HJHS) provides a systematic and robust measure of joint impairment. The MRI Scoring System has been designed to provide a comprehensive scoring system combining both progressive and additive scales. The Functional Independence Score for Haemophilia (FISH) has been developed to assess performance of functional activities and can be used in conjunction with the Haemophilia Activities List (HAL) which provides a self report measure of function. It is recommended that both measures are evaluated as these tools measure different constructs. Further refinement and testing of the psychometric properties of all of these tools is in progress. More widespread use of these tools will enable the sharing of data across the world so promoting best practice and ultimately enhancing patient care.

- Lonafarnib is an orally bio-available farnesyltransferase inhibitor that prevents farnesylation of specific target proteins including Ras. In a multicenter study, 67 patients with advanced myelodysplastic syndrome (MDS) and chronic myelomonocytic leukemia (CMML) were treated with a continuous oral dose of 200-300 mg of lonafarnib and were evaluated for hematologic, pathologic and pharmacodynamic response. The median age of patients was 70 years (range 44-86). There were 32 patients with MDS (RAEB-20 and RAEB-t-12) and 35 with CMML. Overall 16 (24%) of the patients responded with two patients achieving a complete remission and one a partial response. Responses were seen in 6/32 and 10/35 patients with MDS and CMML, respectively. Of the 19 patients who were platelet transfusion-dependent prior to treatment, 5 (26%) became transfusion-free for a median duration of 185 days. A decrease in the farnesylation of the HDJ-2 protein measured in patient-derived cells was observed in the majority of patients during treatment with lonafarnib, but no clear correlation between changes in farnesylation and clinical effect could be made. Gastrointestinal toxicity was significant with 19% of patients discontinuing therapy due to diarrhea, nausea and/or anorexia. Lonafarnib has demonstrable activity in patients with advanced MDS and CMML.
