Best practices in active and student-centered learning in physiology classes.

This review article includes our analysis of the literature and our own experiences in using various types of active learning as best practices for evidence-based teaching in physiology. We have evaluated what physiology students should be expected to learn and what are specific challenges to enhancing their learning of physiology principles. We also consider how the instructor should design his or her teaching to improve buy-in from both students and other faculty members.

Designing and implementing a physiology course for a new doctoral occupational therapy program with student feedback.

Recently, the Occupational Therapy Department requested a custom-designed medical physiology course for the students in the new occupational therapy doctoral program. The first author, a physiologist with extensive experience in teaching both undergraduate preprofessional and medical students in human physiology, was recruited to design and implement the course. The course was designed to be consistent with the constructivist philosophy that guides the occupational therapy curriculum.

How do the Institutes on Teaching and Learning (ITLs) nurture the members of the Physiology Educators Community of Practice (PECOP)?

Do you teach physiology? Do you use best practices when you teach physiology? Have you ever thought about conducting educational research? Do you need collaborators to help with ideas for educational research or to expand your research populations? The American Physiological Society (APS) Teaching Section has developed a biennial Institute on Teaching and Learning (ITL) through the APS Conference Program to address these issues. The first institute was held in June 2014, and the second institute was held in June 2016. A Physiology Education Community of Practice (PECOP) was created to help connect the institute participants and other physiology educators and to share evidence-based teaching in physiology at all education levels.

An evolution in student-centered teaching.

The American Physiological Society (APS) Teaching Section annually honors an educator through its Claude Bernard Distinguished Lecture at the Experimental Biology meeting. Since I knew about my selection for almost a year, I had a long time to think about what I wanted to say and how I wanted to say it. The theme of my presentation was "nothing in education makes sense except in the light of student learning.

What is the American Physiological Society's ITL and who are the members of PECOP?

The American Physiological Society Teaching Section has developed a biennial Institute on Teaching and Learning (ITL) through the APS Conference Program. The first ITL was held in June 2014, and the second ITL will be in June 2016. A Physiology Education Community of Practice was created to help connect the institute participants and other physiology educators to share evidence-based teaching in physiology at all education levels and ideas for the Scholarship of Teaching and Learning and Discipline-Based Education Research in physiology.

The development and implementation of a new medical biology major including physiology.

In response to the Howard Hughes Medical Institute/Association of American Medical Colleges Scientific Foundations for Future Physicians (SFFP) report and a concern for better preparing undergraduates for future doctoral programs in the health professions, the deans of the College of Arts and Sciences and Division of Basic Biomedical Sciences of Sanford School of Medicine of the University of South Dakota formed an ad hoc Premedical Curriculum Review Committee with representatives from the science departments and medical school. The Committee began by reviewing the university's suggested premedical curriculum and matching it to the proposed competencies from the SFFP to document duplications and deficiencies. The proposed changes in the Medical College Admission Test for 2015 were also evaluated.

Myeloid neoplasms secondary to plasma cell myeloma: an intrinsic predisposition or therapy-related phenomenon? A clinicopathologic study of 41 cases and correlation of cytogenetic features with treatment regimens.

We describe 41 cases of myeloid neoplasms (MNs) secondary to plasma cell myeloma (PCM). The types of MN included myelodysplastic syndrome (MDS) in 34 (82.9%), acute myeloid leukemia (AML) in 4 (9.

MLL duplication in a pediatric patient with B-cell lymphoblastic lymphoma.

Lymphoblastic lymphoma is the second most common type of non-Hodgkin lymphoma seen in children. Approximately, 90% of lymphoblastic lymphomas arise from T cells, with the remaining 10% being B-cell-lineage derived. Although T-cell lymphoblastic lymphoma most frequently occurs in the anterior mediastinum (thymus), B-cell lymphoblastic lymphoma (B-LBL) predominates in extranodal sites such as skin and bone.

Influence of a rural family medicine rotation on residency selection: MS3 versus MS4.

Background And Objectives: Many family medicine educators feel that a required clinical rotation in family medicine has a positive influence on medical students' selection of family medicine residencies. We investigated the effect of a rural family medicine rotation on students' residency choices and examined the differences between a third-year and a fourth-year rotation.

Methods: We surveyed 1,260 students before and after they participated in a required rural family medicine rotation.

SET oncoprotein overexpression in B-cell chronic lymphocytic leukemia and non-Hodgkin lymphoma: a predictor of aggressive disease and a new treatment target.

B-cell chronic lymphocytic leukemia (CLL), an incurable leukemia, is characterized by defective apoptosis. We found that the SET oncoprotein, a potent inhibitor of the protein phosphatase 2A (PP2A) tumor suppressor, is overexpressed in primary CLL cells and B-cell non-Hodgkin lymphoma (NHL) cell line cells. In CLL, increased levels of SET correlated significantly with disease severity (shorter time to treatment and overall survival).

College of American Pathologists/American College of Medical Genetics proficiency testing for constitutional cytogenomic microarray analysis.

Purpose: To evaluate the feasibility of administering a newly established proficiency test offered through the College of American Pathologists and the American College of Medical Genetics for genomic copy number assessment by microarray analysis, and to determine the reproducibility and concordance among laboratory results from this test.

Methods: Surveys were designed through the Cytogenetic Resource Committee of the two colleges to assess the ability of testing laboratories to process DNA samples provided and interpret results. Supplemental questions were asked with each Survey to determine laboratory practice trends.

Donor cell-derived leukemias/myelodysplastic neoplasms in allogeneic hematopoietic stem cell transplant recipients: a clinicopathologic study of 10 cases and a comprehensive review of the literature.

We report 10 cases of donor cell leukemia (DCL). All cases except the case of chronic lymphocytic leukemia had anemia, neutropenia, and/or thrombocytopenia when DCL was diagnosed. Eight cases with sex-mismatched hematopoietic stem cell transplant (HCT) showed donor gonosomal complements, suggesting DCL.

Insights into digestion and absorption of major nutrients in humans.

Nutrient digestion and absorption is necessary for the survival of living organisms and has evolved into the complex and specific task of the gastrointestinal (GI) system. While most people simply assume that their GI tract will work properly to use nutrients, provide energy, and release wastes, few nonscientists know the details about how various nutrients are digested and how the breakdown products traverse the cells lining the small intestine to reach the blood stream and to be used by the other cells of the body. There have been several recent discoveries of new transporters that likely contribute to the absorption of oligopeptides and fatty acids.

Donor cell leukemia in umbilical cord blood transplant patients: a case study and literature review highlighting the importance of molecular engraftment analysis.

Donor cell neoplasms are rare complications of treatment regimens that involve stem cell transplantation for hematological malignancies, myelodysplastic processes, or certain genetic or metabolic disorders. We report a case of donor cell leukemia in a pediatric patient with a history of acute myeloid leukemia that manifested as recurrent AML FAB type M5 fourteen months after umbilical cord blood transplantation. Although there was some immunophenotypic drift from the patient's original AML and their posttransplant presentation, the initial pathological impression was of recurrent disease.

A single tube, four-color flow cytometry assay for evaluation of ZAP-70 and CD38 expression in chronic lymphocytic leukemia.

We describe a simple and robust flow cytometry assay for ZAP-70 and CD38 expression. The steps required to validate this assay in a clinical flow cytometry laboratory are described. Two criteria were used to characterize ZAP-70 expression into positive, negative, and indeterminate categories and applied to 111 cases of chronic lymphocytic leukemia (CLL) resulting in 29.

A genomic approach to improve prognosis and predict therapeutic response in chronic lymphocytic leukemia.

Purpose: Chronic lymphocytic leukemia (CLL) is a B-cell malignancy characterized by a variable clinical course. Several parameters have prognostic capabilities but are associated with altered response to therapy in only a small subset of patients.

Experimental Design: We used gene expression profiling methods to generate predictors of therapy response and prognosis.

Reduced ATR or Chk1 expression leads to chromosome instability and chemosensitization of mismatch repair-deficient colorectal cancer cells.

Genomic instability in colorectal cancer is categorized into two distinct classes: chromosome instability (CIN) and microsatellite instability (MSI). MSI is the result of mutations in the mismatch repair (MMR) machinery, whereas CIN is often thought to be associated with a disruption in the APC gene. Clinical data has recently shown the presence of heterozygous mutations in ATR and Chk1 in human cancers that exhibit MSI, suggesting that those mutations may contribute to tumorigenesis.

Channels active in the excitability of nerves and skeletal muscles across the neuromuscular junction: basic function and pathophysiology.

Ion channels are essential for the basic physiological function of excitable cells such as nerve, skeletal, cardiac, and smooth muscle cells. Mutations in genes that encode ion channels have been identified to cause various diseases and disorders known as channelopathies. An understanding of how individual ion channels are involved in the activation of motoneurons and their corresponding muscle cells is essential for interpreting basic neurophysiology in nerves, the heart, and skeletal and smooth muscle.
