Introduction: Historical Cultures and Education in Transition
In the Introduction Carretero, Berger and Grever present an overview of the main issues that are currently discussed in relation to historical culture and history education. They introduce the 38 chapters of the Palgrave Handbook of Research in Historical Culture and Education written by scholars from the Americas, Europe and Asia, providing an international and global perspective on these matters. The Handbook is organized into four parts: (a) Historical Culture and Public Uses of History; (b) The Appeal of the Nation in History Education of Postcolonial Societies; (c) Reflections on History Learning and Teaching; (d) Educational Resources: Curricula, Textbooks and New Media. The Introduction also explains the interdisciplinary approach of the Handbook, evidenced by contributions from History, Education, Social and Cognitive Psychology and other Social Sciences
Palgrave Handbook of Research in Historical Culture and Education
This handbook provides a broad overview of current research and theories on historical culture and education. It consists of thirty-nine chapters divided into four parts: I. Historical Culture: Conceptualizing the Public Uses of History; II. The Appeal of the Nation in History Education of Postcolonial Societies; III. Reflections on History Learning and Teaching; IV. Educational Resources: Curricula, Textbooks and New Media. The handbook integrates contributions of researchers from history, historical theory, education, collective memory, museum studies, heritage, social and cognitive psychology, and other social sciences, stimulating an interdisciplinary dialogue. Contributors come from various countries of Northern and Southern America, Europe, North-Africa, Australia and Asia, providing an international perspective that does justice to the complexity of this field of study. The Palgrave Handbook of Research in Historical Culture and Education provides state-of-the-art research, focusing on how citizens and societies make sense of the past through different ways of representing it

The long noncoding RNA, treRNA, decreases DNA damage and is associated with poor response to chemotherapy in chronic lymphocytic leukemia.
The study of long noncoding RNAs (lncRNAs) is an emerging area of cancer research, in part due to their ability to serve as disease biomarkers. However, few studies have investigated lncRNAs in chronic lymphocytic leukemia (CLL). We have identified one particular lncRNA, treRNA, which is overexpressed in CLL B-cells. We measured transcript expression in 144 CLL patient samples and separated samples into high or low expression of treRNA relative to the overall median. We found that high expression of treRNA is significantly associated with shorter time to treatment. High treRNA also correlates with poor prognostic indicators such as unmutated IGHV and high ZAP70 protein expression. We validated these initial findings in samples collected in a clinical trial comparing the nucleoside analog fludarabine alone or in combination with the alkylating agent cyclophosphamide in untreated CLL samples collected prior to starting therapy (E2997). High expression of treRNA was independently prognostic for shorter progression free survival in patients receiving fludarabine plus cyclophosphamide. Given these results, in order to study the role of treRNA in DNA damage response we generated a model cell line system where treRNA was over-expressed in the human B-CLL cell line OSU-CLL. Relative to the vector control line, there was less cell death in OSU-CLL over-expressing treRNA after exposure to fludarabine and mafosfamide, due in part to a reduction in DNA damage. Therefore, we suggest that treRNA is a novel biomarker in CLL associated with aggressive disease and poor response to chemotherapy through enhanced protection against cytotoxic mediated DNA damage
A phase I trial of Flavopiridol in relapsed multiple myeloma
PURPOSE:
Flavopiridol is primarily a cyclin-dependent kinase-9 inhibitor, and we performed a dose escalation trial to determine the maximum tolerated dose and safety and generate a pharmacokinetic (PK) profile.
METHODS:
Patients with a diagnosis of relapsed myeloma after at least two prior treatments were included. Flavopiridol was administered as a bolus and then continuous infusion weekly for 4 weeks in a 6-week cycle.
RESULTS:
Fifteen patients were treated at three dose levels (30 mg/m(2) bolus, 30 mg/m(2) CIV to 50 mg/m(2) bolus, and 50 mg/m(2) CIV). Cytopenias were significant, and elevated transaminases (grade 4 in 3 patients, grade 3 in 4 patients, and grade 2 in 3 patients) were noted but were transient. Diarrhea (grade 3 in 6 patients and grade 2 in 5 patients) did not lead to hospital admission. There were no confirmed partial responses although one patient with t(4;14) had a decrease in his monoclonal protein >50 % that did not persist. PK properties were similar to prior publications, and immunohistochemical staining for cyclin D1 and phospho-retinoblastoma did not predict response.
CONCLUSIONS:
Flavopiridol as a single agent given by bolus and then infusion caused significant diarrhea, cytopenias, and transaminase elevation but only achieved marginal responses in relapsed myelom

Development of a distributed international patient data registry for hairy cell leukemia
Hairy cell leukemia (HCL) is a rare lymphoproliferative disorder, comprising only 2% of all leukemias. The Hairy Cell Leukemia Foundation (HCLF) has developed a patient data registry to enable investigators to better study the clinical features, treatment outcomes, and complications of patients with HCL. This system utilizes a centralized registry architecture. Patients are enrolled at HCL Centers of Excellence (COE) or via a web-based portal. All data are de-identified, which reduces regulatory burden and increases opportunities for data access and re-use. To date, 579 patients have been enrolled in the registry. Efforts are underway to engage additional COE’s to expand access to patients across the globe. This international PDR will enable researchers to study outcomes in HCL in ways not previously possible due to the rarity of the disease and will serve as a platform for future prospective research
