Protein Targeting Gone Awry - National Center for Case Study Teaching in Science - 0 views

  •  
    This case study synthesizes students' knowledge of the central dogma and cell structure by examining a rare health disorder in order to understand protein targeting and its medical consequences. Students first identify the molecular alteration in affected members of a family with renal Fanconi syndrome as reported in the New England Journal of Medicine (2014). Students then use an online bioinformatics tool to analyze the wildtype and mutant proteins and examine their subcellular localization. Finally, students use this information to explain the symptoms of affected family members. The case is delivered with a PowerPoint presentation that includes a selection of brainstorming prompts and "clicker questions." Students complete a worksheet (included in the teaching notes) before class, making the activity suitable for a flipped classroom. A second worksheet (also included in the teaching notes) is completed during class. The case is written for an introductory biology course for majors, but could also be used as a unit capstone in a non-majors human biology course; the case is also scalable to upper division courses in physiology that specifically explore kidney function.

A Fatal Bite - National Center for Case Study Teaching in Science (NCCSTS) - 0 views

  •  
    In this case study, students follow "Mr. Okoro" as he makes the long journey with his sick daughter "Ada" to seek medical attention at the nearest clinic in Enugu, Nigeria. It is the rainy season, and "Dr. Fabian" from the Division of Parasitic Diseases and Malaria has been called in to investigate a suspected outbreak of malaria. Students learn about the circumstances in Ada's background that may have led to her illness, and then adopt the perspective of Dr. Fabian as she investigates the outbreak. They consider the epidemiological triangle, the different stages of the Plasmodium parasite lifecycle and how it leads to malaria, and evaluate the broader societal factors and future implications of malaria in Sub-Saharan Africa. The case was designed for upper-level global health, public health, and human biology courses, but could also be adapted for general biology, health studies, infectious disease, and epidemiology courses.

The Terrible Toll of the Tuskegee Study - The Atlantic - 0 views

  •  
    Known officially as the Tuskegee Study of Untreated Syphilis in the Negro Male, the 40-year experiment run by Public Health Service officials followed 600 rural black men in Alabama with syphilis over the course of their lives, refusing to tell patients their diagnosis, refusing to treat them for the debilitating disease, and actively denying some of them treatment.

Georgetown-led Group Recommends Policy Changes Regarding Sex Diversity in Research | Ge... - 0 views

  •  
    FEBRUARY 20, 2015-A diverse group of experts from academia, industry and advocacy convened by a Georgetown researcher is offering recommendations to the National Institutes of Health (NIH) regarding how to address the overreliance of male cells and animals used in preclinical studies. The recommendations come as the federal research institution works to increase the inclusion of female animal models and achieve a balance in the use of male and female cells and animals in lab research.

Research News: New Genetic Syndrome Linked to Missing DNA | Howard Hughes Medical Insti... - 0 views

  •  
    [ February 17, 2008 ] People who lack a certain large segment of DNA have a previously unrecognized syndrome characterized by mental retardation, seizures, and slight physical abnormalities, according to a genetic analysis conducted by HHMI investigator Evan E. Eichler at the University of Washington School of Medicine and a team of international collaborators. The deleted DNA segment is responsible for just a small percentage of cases of mental retardation, but "when you think about how common mental retardation is," Eichler says, "this deletion has a significant impact on human health."

CRISPR and Other Genome Editing Tools Boost Medical Research and Gene Therapy's Reach |... - 0 views

  •  
    Over the last decade, as DNA-sequencing technology has grown ever faster and cheaper, our understanding of the human genome has increased accordingly. Yet scientists have until recently remained largely ham-fisted when they've tried to directly modify genes in a living cell. Take sickle-cell anemia, for example. A debilitating and often deadly disease, it is caused by a mutation in just one of a patient's three billion DNA base pairs. Even though this genetic error is simple and well studied, researchers are helpless to correct it and halt its devastating effects.

What is DNA Methylation? - 1 views

  •  
    Over recent decades, scientists have made various discoveries about DNA methylation and how vital it is to a number of cellular processes such as embryonic development, X-chromosome inactivation, genomic imprinting, gene suppression, carcinogenesis and chromosome stability. Researchers have linked abnormal DNA methylation to several adverse outcomes, including human diseases.
