A Yellow-Bellied Lawyer? - National Center for Case Study Teaching in Science - 0 views

  •  
    This interrupted case study tells the story of Michael, a Harvard law graduate with a stressful job and a seemingly heavy drinking problem. Students are provided with background information, medical history, and lab results in order to guide them towards determining what is wrong with Michael. This study highlights cirrhosis and the effects of alcohol abuse on the liver. Before beginning the case study, students should have a background in the physiological role of the liver and the breakdown of hemoglobin. Students are asked to use the information provided for them in the case study to gather more information about liver cells and their functions, alcohol, and alcoholic liver damage. Ultimately, using multiple blood tests, the Maddrey's discriminant function (DF) score, and results from a magnetic resonance elastography (MRE), they will diagnose Michael with alcoholic cirrhosis. This case was developed for use in a non-majors physiology course, but could easily be used for a majors class.

The Red Hot Debate about Transmissible Alzheimer's - Scientific American - 0 views

  •  
    For Collinge, this led to a worrying conclusion: that the plaques might have been transmitted, alongside the prions, in the injections of growth hormone-the first evidence that Alzheimer's could be transmitted from one person to another. If true, that could have far-reaching implications: the possibility that 'seeds' of the amyloid-β protein involved in Alzheimer's could be transferred during other procedures in which fluid or tissues from one person are introduced into another, such as blood transfusions, organ transplants and other common medical procedures.

New "Bionic" Leaf Is Roughly 10 Times More Efficient Than Natural Photosynthesis - Scie... - 0 views

  •  
    Chemist Daniel Nocera of Harvard University and his team joined forces with synthetic biologist Pamela Silver of Harvard Medical School and her team to craft a kind of living battery, which they call a bionic leaf for its melding of biology and technology. The device uses solar electricity from a photovoltaic panel to power the chemistry that splits water into oxygen and hydrogen.

A cinematic approach to drug resistance | Harvard Gazette - 0 views

  •  
    In a creative stroke inspired by Hollywood wizardry, scientists from Harvard Medical School and Technion-Israel Institute of Technology have designed a simple way to observe how bacteria move as they become impervious to drugs. The experiments, described in the Sept. 9 issue of Science, are thought to provide the first large-scale glimpse of the maneuvers of bacteria as they encounter increasingly higher doses of antibiotics and adapt to survive - and thrive - in them.

Long-Dreaded Superbug Found in Human and Animal in U.S. - Phenomena: Germination - 0 views

  •  
    Department of Defense researchers disclosed Thursday in a report placed online by the journal Antimicrobial Agents and Chemotherapy that a 49-year-old woman who sought medical care at a military-associated clinic in Pennsylvania last month, with what seemed to be a urinary tract infection, was carrying a strain of E. coli resistant to a wide range of drugs. That turned out to be because the organism carried 15 different genes conferring antibiotic resistance, clustered on two "mobile elements" that can move easily among bacteria. One element included the new, dreaded gene mcr-1.

DNA study builds picture of Ice Age Europeans | Cosmos - 0 views

  •  
    The fates of ice age human groups in Europe were closely linked to climate change, according to an unprecedented study of the genomes of 51 individuals who lived between 45,000 years ago (when modern humans arrived in Europe) and 7,000 years ago. "We see multiple, huge movements of people displacing previous ones," David Reich of the Harvard Medical School said. "During this first four-fifths of modern human history in Europe, history is just as complicated as it is during the last fifth that we know so much more about."

East Meets West - National Center for Case Study Teaching in Science - 0 views

  •  
    Another case is ready for you: "East Meets West: An Infectious Disease Case" by Harry M. Zollars, Catherine D. Santanello, and Marcelo J. Nieto, Department of Pharmaceutical Sciences, Southern IL University Edwardsville.   Ying is sick and is progressively getting worse. His parents' clashing views on Eastern and Western medicine prevent them from agreeing on a course of treatment. As the case unfolds, students follow the progression of their son's illness. After a physician is finally seen and the results of tests are evident, students should be able to narrow the list of possible etiological agents and suggest a potential treatment. In addition, the students should integrate the different health beliefs into the final treatment as well as the aspects of patient counseling. The case works well as an interrupted case that can be assigned to individual students or student teams. This case is appropriate for graduate courses with a component in health care, therapeutics, medicinal chemistry, medicinal plants, microbiology, epidemiology, or cultural competency. Instructors can choose to focus only on the medical components of the case or incorporate the cultural and ethical aspects, depending on course goals and subject area.

New blood test can predict future breast cancer | EurekAlert! Science News - 0 views

  •  
    The researchers' approach to developing the method was adopted from food science, where it is used for control of complex industrial processes. Basically, it involves handling and analysing huge amounts of biological data in a holistic and explorative way. The researchers analysed all compounds a blood sample contains instead of - as is often done in health and medical science - examining what a single biomarker means in relation to a specific disease. "When a huge amount of relevant measurements from many individuals is used to assess health risks - here breast cancer - it creates very high quality information. The more measurements our analyses contain, the better the model handles complex problems," continued Professor Rasmus Bro.

Home | 1000 Genomes - 0 views

  •  
    The 1000 Genomes Project is an international collaboration to produce an extensive public catalog of human genetic variation, including SNPs and structural variants, and their haplotype contexts. This resource will support genome-wide association studies and other medical research studies. The genomes of about 2500 unidentified people from about 25 populations around the world will be sequenced using next-generation sequencing technologies. The results of the study will be freely and publicly accessible to researchers worldwide. Further information about the project is available in the About tab. Information about downloading, browsing or using the 1000 Genomes data is available in the Data tab.

Whole Genome Scans Aren't Quite Ready For Your Doctor's Office : Shots - Health News : NPR - 0 views

  •  
    or more than a decade scientists have been saying that a genomic revolution will transform medicine, making it possible to scan all of a person's DNA to predict risk and customize medical care. Well, we've got the machines. Where's the revolution? Getting closer, say researchers at Stanford University, who tested the technology on 12 people. But not quite ready for every doctor's office.

Genomics > Table of Pharmacogenomic Biomarkers in Drug Labeling - 0 views

  •  
    Pharmacogenomics can play an important role in identifying responders and non-responders to medications, avoiding adverse events, and optimizing drug dose. Drug labeling may contain information on genomic biomarkers and can describe: Drug exposure and clinical response variability Risk for adverse events Genotype-specific dosing Mechanisms of drug action Polymorphic drug target and disposition genes The table below lists FDA-approved drugs with pharmacogenomic information in their labeling. The labeling for some, but not all, of the products includes specific actions to be taken based on the biomarker information. Pharmacogenomic information can appear in different sections of the labeling depending on the actions. For more information, please refer to the appropriate labeling guidance.

What did dogs teach humans about diabetes? - Duncan C. Ferguson | TED-Ed - 0 views

  •  
    Diabetes has a history dating back to Ancient Greece. Our treatment of it, however, is more recent and was originally made possible with the help of man's best friend. Due to physiological traits shared with humans, dogs have saved countless lives through the discovery of insulin. Duncan C. Ferguson shares the story of the canine's great contribution to man -- and how we can all reap the medical benefits.
