However, LCNEC in the case was resistant to the chemotherapy. In our review of published works, ovarian cancer cases with LCNEC show poor prognoses regardless of adjuvant chemotherapy following complete resection. Median overall survival was 10months
in stage I cases. Development of chemotherapy Rigosertib sensitive for LCNEC is needed.”
“Myelodysplastic syndrome (MDS) is composed of a diverse spectrum of hematopoietic stem cell malignancies characterized by ineffective blood cell production. Many MDS patients are dependent on red blood cell (RBC) transfusions for symptomatic management of refractory anemia. Iron overload ensues when the iron acquired from transfused RBCs exceeds body storage capacity, thereby raising the risk for end organ damage. This is of GW-572016 greatest concern in patients with lower-risk MDS whose expected survival is measured in years. Transfusion dependence is associated with shorter survival and an increased risk for progression to acute myeloid leukemia (AML) in transfusion-dependent patients. Application of recent advances in the treatment of MDS can reduce or eliminate the need for transfusions, thus minimizing the risk of iron overload. Case control studies, prospective surveys, and phase II studies indicate that iron chelation therapy
reduces iron load as measured by changes in serum ferritin and may prolong overall survival. Iron chelation strategies include oral agents such as deferasirox (Exjade (R), Novartis Pharmaceuticals Corp, East Hanover, NJ), deferiprone (Ferriprox (R), Apotex Europe BV, Leiden, the Netherlands) and, for those patients who are intolerant of or for whom oral therapy is ineffective, parenteral
administration of deferoxamine (Desferal (R), Novartis). This review presents the data related to iron overload in MDS, including its prevalence, diagnosis, clinical impact, and management.”
“Mercury (Hg) is a global contaminant impacting even remote environments. In alpine watersheds, glacial meltwater is a source of Hg, which accumulated in glaciers during the 1960-1980 cooling cycle. The considerable variation observed for Hg exposure of alpine animals in proximal watersheds could result from differences among those watersheds in Hg loading from glacial meltwater. Alternatively, variation may be check details the result of hydrology, atmospheric Hg deposition patterns, or food web characteristics. To examine those possibilities, we measured Hg in ospreys (Pandion haliaetus), apex predators in 15 watersheds in western Canada. Mercury levels in feathers of nestlings increased with increasing modeled atmospheric deposition rates and decreased with lake size. In eggs mercury decreased with delta C-13, an indicator of food web structure, and with pH and elevation. Thus, Hg levels in chicks were strongly associated with local patterns relevant when the chicks were growing (e.g.
