1.  iBiology: communicating the process of science 
Molecular Biology of the Cell  2014;25(15):2217-2219.
The Internet hosts an abundance of science video resources aimed at communicating scientific knowledge, including webinars, massive open online courses, and TED talks. Although these videos are efficient at disseminating information for diverse types of users, they often do not demonstrate the process of doing science, the excitement of scientific discovery, or how new scientific knowledge is developed. iBiology (, a project that creates open-access science videos about biology research and science-related topics, seeks to fill this need by producing videos by science leaders that make their ideas, stories, and experiences available to anyone with an Internet connection.

2.  An Overview of Canadian and U.S. Approaches to Drug Regulation and Responses to Postmarket Adverse Drug Reactions 
Over the years, drug products, including those indicated for diabetes, have been withdrawn from the marketplace because of quality concerns and/or severe adverse drug reactions. While the drug regulatory process is designed to detect, among other things, adverse drug reactions before a drug receives marketing authorization, for various reasons, premarket detection of all potential adverse reactions associated with a drug may not be possible. As such, regulatory authorities must also react to and manage adverse reactions identified at the postmarket stage. In this article, we provide a general overview of drug regulation in Canada and the United States and consider an example of a drug indicated for the treatment of diabetes and how newly identified potential safety concerns were managed in the postmarket environment.

4.  Specialist Physicians in Geriatrics—Report of the Canadian Geriatrics Society Physician Resource Work Group* 
Canadian Geriatrics Journal  2012;15(3):68-79.
At the 2011 Annual Business Meeting of the Canadian Geriatrics Society (CGS), an ad hoc Work Group was struck to submit a report providing an estimate of the number of physicians and full-time equivalents (FTEs) currently working in the field of geriatrics, an estimate of the number required (if possible), and a clearer understanding of what has to be done to move physician resource planning in geriatrics forward in Canada.
It was decided to focus on specialist physicians in geriatrics (defined as those who have completed advanced clinical training or have equivalent work experience in geriatrics and who limit a significant portion of their work-related activities to the duties of a consultant).
In 2012, there are 230–242 certified specialists in geriatric medicine and approximately 326.15 FTE functional specialists in geriatrics. While this is less than the number required, no precise estimate of present and future need could be provided, as no attempts at a national physician resource plan in geriatrics based on utilization and demand forecasting, needs-based planning, and/or benchmarking have taken place.
This would be an opportune time for the CGS to become more involved in physician resource planning. In addition to this being critical for the future health of our field of practice, there is increasing interest in aligning specialty training with societal needs (n = 216).

6.  Reproducibility, validity, and responsiveness of cell counts in blown nasal secretions 
Allergy & Rhinology  2011;2(1):3-5.
Cell counts in nasal secretions are not used in routine clinical practice to decide on anti-inflammatory or antimicrobial therapy. This study investigated the reproducibility, reliability (validity), and responsiveness of cell counts in blown nasal secretions with a view to implementing this in routine clinical practice. Nasal secretions were obtained from 19 subjects with allergic rhinitis on 3 days in random order (each separated by 1–2 days) by spontaneously blowing their noses (on 2 days) and by a nasal lavage by the modified Grunberg method on the 3rd day. Total and differential cell counts were performed after dispersing the solutions with dithiothreitol as described previously. At the end of the study, subjects had 1 week of open label treatment with nasal corticosteroids if they had nasal eosinophilia or an antibiotic if they had nasal neutrophilia. If the cell counts were normal, they were not treated. The proportion of eosinophil (%) was highly reproducible (intraclass correlation coefficient [ICC], 0.93), and the total cell count (×106/g) and the proportion of neutrophil (%) were modestly reproducible in blown nasal secretions (ICC, 0.46 and 0.55, respectively). The total cell count was consistently and significantly higher in the blown nasal secretions. The proportion of eosinophils (Rs = 0.4; p < 0.05) and neutrophils (Rs = 0.6; p < 0.05) showed modest correlation in the two types of samples. The responsiveness index for eosinophil count was 4.0 and for neutrophil count was 1.5. Total and differential cell counts can be reliably and reproducibly obtained from spontaneously blown nasal secretions. The cell counts are responsive to treatment and can help identify allergic and infective rhinosinusitis and guide therapy and are easy to implement in routine clinical practice.

7.  Genes Required for Mitotic Spindle Assembly in Drosophila S2 Cells 
Science (New York, N.Y.)  2007;316(5823):417-421.
The formation of a metaphase spindle, a bipolar microtubule array with centrally aligned chromosomes, is a prerequisite for the faithful segregation of a cell’s genetic material. Using a full-genome RNA interference screen of Drosophila S2 cells, we identified about 200 genes that contribute to spindle assembly, more than half of which were unexpected. The screen, in combination with a variety of secondary assays, led to new insights into how spindle microtubules are generated; how centrosomes are positioned; and how centrioles, centrosomes, and kinetochores are assembled.

8.  Target prediction for small, noncoding RNAs in bacteria 
Nucleic Acids Research  2006;34(9):2791-2802.
Many small, noncoding RNAs in bacteria act as post-transcriptional regulators by basepairing with target mRNAs. While the number of characterized small RNAs (sRNAs) has steadily increased, only a limited number of the corresponding mRNA targets have been identified. Here we present a program, TargetRNA, that predicts the targets of these bacterial RNA regulators. The program was evaluated by assessing whether previously known targets could be identified. The program was then used to predict targets for the Escherichia coli RNAs RyhB, OmrA, OmrB and OxyS, and the predictions were compared with changes in whole genome expression patterns observed upon expression of the sRNAs. Our results show that TargetRNA is a useful tool for finding mRNA targets of sRNAs, although its rate of success varies between sRNAs.
