Professional skills for physiology majors: defining and refining.

Changing labor markets require a workforce that is broadly trained for a variety of possible careers. Recognizing this, government and industry representatives, along with students and their families, are encouraging universities and colleges to focus more on developing transferable skills to maximize employability of their graduates. In response, academic institutions and professional organizations have begun to develop lists of transferable professional skills that they expect students to have acquired on graduation. At the 2018 Physiology Majors Interest Group (P-MIG) meeting, participants stated that there was a need to define a list of professional skills for undergraduates completing a physiology major. To this end, a professional skills committee was established. Initially members of the committee worked together to develop a draft list of skills. An iterative process of refining the list was then undertaken through presentations/small-group discussions at appropriate international meetings and via an online survey. Over 60 physiology educators, the majority of whom teach in undergraduate programs, provided input. The final list (presented here) consists of 13 skills grouped in four broad categories: think critically, communicate effectively, behave in a socially and scientifically responsible manner, and demonstrate laboratory proficiency. It is anticipated that the list will be used for curriculum mapping and to guide the development of new physiology courses and major programs. The professional skills committee now plans to develop rubrics and tools that will allow for the assessment of these skills.

Physiology educators find community in the Physiology Majors Interest Group.

The Physiology Majors Interest Group (P-MIG) is a grass-roots consortium of physiology educators with the common interest of creating program-level guidelines for undergraduate physiology and related programs. A key component of the consortium's activities are the annual P-MIG conferences that have been held at different universities over the past 3 yr (Michigan State University, 2017; University of Arizona, 2018; and University of Minnesota, 2019). Postconference surveys indicate that the conferences are highly valued by the participants, as they have provided an opportunity to get to know others who are passionate about undergraduate education, to discuss best practices in program and course delivery, and to form working groups with the goal to develop national and international guidelines for physiology program delivery and assessment.

Research preparedness paves the way to respond to pandemic H1N1 2009 influenza virus.

The international community has been preparing for an influenza pandemic because of the threat posed by H5N1 avian influenza. Over the past several years, Canada has dedicated funding to boost capacity for research, and public health and health care system readiness and response in the event of a pandemic. The current H1N1/09 influenza pandemic is now testing our readiness. From a research perspective, the present commentary discusses how have we prepared, along with the research gaps. We conclude that: sources of pandemics are not always predictable; investment in the past few years has paid off in a rapid response to pandemic H1N1/09 virus in Canada; and research to meet the challenges of infectious diseases has to be done on an ongoing long-term basis, and its funding has to be flexible, available and predictable to maintain capacity and expertise. In addition, new vaccine technologies are needed to develop and produce vaccines for public health emergencies in a timely fashion.

Transgenic expression of numb inhibits notch signaling in immature thymocytes but does not alter T cell fate specification.

The conserved adaptor protein Numb is an intrinsic cell fate determinant that functions by antagonizing Notch-mediated signal transduction. The Notch family of membrane receptors controls cell survival and cell fate determination in a variety of organ systems and species. Recent studies have identified a role for mammalian Notch-1 signals at multiple stages of T lymphocyte development. We have examined the role of mammalian Numb (mNumb) as a Notch regulator and cell fate determinant during T cell development. Transgenic overexpression of mNumb under the control of the Lck proximal promoter reduced expression of several Notch-1 target genes, indicating that mNumb antagonizes Notch-1 signaling in vivo. However, thymocyte development, cell cycle, and survival were unperturbed by mNumb overexpression, even though transgenic Numb was expressed at an early stage in thymocyte development (CD4(-)CD8(-)CD3(-) cells that were CD44(+)CD25(+) or CD44(-)CD25(+); double-negative 2/3). Moreover, bone marrow from mNumb transgenic mice showed no defects in thymopoiesis in competitive repopulation experiments. Our results suggest that mNumb functions as a Notch-1 antagonist in immature thymocytes, but that suppression of Notch-1 signaling at this stage does not alter gammadelta/alphabeta or CD4/CD8 T cell fate specification.
