Workshop on molecular animation

From February 25 to 26, 2010, in San Francisco, the Resource for Biocomputing, Visualization, and Informatics (RBVI) and the National Center for Macromolecular Imaging (NCMI) hosted a molecular animation workshop for 21 structural biologists, molecular animators, and creators of molecular visualization software. Molecular animation aims to visualize scientific understanding of biomolecular processes and structures. The primary goal of the workshop was to identify the necessary tools for producing high-quality molecular animations, understanding complex molecular and cellular structures, creating publication supplementary materials and conference presentations, and teaching science to students and the public. Another use of molecular animation emerged in the workshop: helping to focus scientific inquiry about the motions of molecules and enhancing informal communication within and between laboratories.     

ePMV embeds molecular modeling into professional animation software environments

Increasingly complex research has made it more difficult to prepare data for publication, education, and outreach. Many scientists must also wade through black-box code to interface computational algorithms from diverse sources to supplement their bench work. To reduce these barriers we have developed an open-source plug-in, embedded Python Molecular Viewer (ePMV), that runs molecular modeling software directly inside of professional 3D animation applications (hosts) to provide simultaneous access to the capabilities of these newly connected systems. Uniting host and scientific algorithms into a single interface allows users from varied backgrounds to assemble professional quality visuals and to perform computational experiments with relative ease. By enabling easy exchange of algorithms, ePMV can facilitate interdisciplinary research, smooth communication between broadly diverse specialties, and provide a common platform to frame and visualize the increasingly detailed intersection(s) of cellular and molecular biology.

Crafting Grand Cra Chocolates in Contemporary France

C'est un magasin où le chocolat règne en maître, traité par un maître. C'est du travail cent pour cent artisanal au sens "artist" du terme, qui sait tirer de la sublime fève d'Amérique la substantifique splendeur.1     

Support for a career in science

I am so very honored to receive the Women in Cell Biology Sandra K. Masur Senior Leadership Award from the American Society for Cell Biology (ASCB), particularly because many of the previous awardees have served as mentors and sources of inspiration throughout my own career. I also thank the ASCB for always striving to be maximally inclusive, in terms of both the scientists it supports and its broad vision of what constitutes cell biology. As a graduate student I gave one of my first talks at an ASCB meeting, and I am proud to have been an ASCB member for almost 30 years. In this essay, I describe my own career to illustrate the support that I believe is needed to achieve a career in science.

Crafting fidelity: pedagogical creativity in kathak dance

Through a phenomenological account of apprenticeship in the North Indian dance form of kathak, I show how skills are adapted and changed through the ingenuity and innovation required in teaching to new generations of students. The traditional pedagogical model for learning in the Indian arts, the guru‐shishya parampara (master‐disciple relationship), has historically been based on imitative and repetitive pedagogies. Yet close examination reveals less conspicuous forms of creativity at work in the process of reproducing the tradition with fidelity; this improvisational work is further heightened in the demands of teaching in the diaspora. As teachers create opportunities for experiential learning, a spectrum of pedagogical tactics, scaffolding strategies, and coaching competencies are developed and accumulate as this tradition is passed on from one generation to the next. The pedagogical work in crafting fidelity can, in fact, produce its own kind of knowledge, which, ironically, can add new elements to the tradition in unexpected ways. In one unique case – the example of ‘kathak yoga’ – the pedagogical adaptations of kathak artist Pandit Chitresh Das elicited a creative response, a new scaffolding technique that would eventually be incorporated into the repertoire as a skill in itself. Pedagogical process, in this sense, was creative process.     

Prolonged suspended animation in puppies

Three groups of a total of 26 puppies were subjected to surface-induced hypothermia with or without limited left-heart bypass to seek recovery after 2.5-hr total circulatory arrest. In spite of various protective measures, surface-induced hypothermia which was carried out until the effective circulation ceased, failed to protect the animal from 2.5-hr circulatory arrest. With a combination of limited leftheart bypass, the central nervous tissue tolerated the procedure better than expected. Metabolic derangements, although severe immediately after the procedure, were reversible. Respiratory distress was a serious problem, which was considerably alleviated in the 3rd group of 10 puppies by perfusion of the lung with a solution approximating the intracellular electrolyte composition. Six puppies of this group survived the procedure, 5 without any persistent disorders. These results indicate the possibility of 2.5-hr hypothermie circulatory arrest.     

Determinants of choosing a career in family medicine

Background

Student choice is an important determinant of the distribution of specialties of practising physicians in many countries. Understanding characteristics at entry into medical school that are associated with the choice of residency in family medicine can assist medical schools in admitting an appropriate mix of students to serve the health care needs of their regions.

Methods

From 2002 to 2004, we collected data from students in 15 classes at 8 of 16 Canadian medical schools at entry. Surveys included questions on career choice, attitudes to practice and socio-demographic characteristics. We followed students prospectively with these data linked to their residency choice. We used multiple logistic regression analysis to identify entry characteristics that predicted a student’s ultimate career choice in family medicine.

Results

Of 1941 eligible students in the participating classes, 1542 (79.4%) contributed data to the final analyses. The following 11 entry variables predicted whether a student named family medicine as his or her top residency choice: being older, being engaged or in a long-term relationship, not having parents with postgraduate university education nor having family or close friends practicing medicine, having undertaken voluntary work in a developing nation, not volunteering with elderly people, desire for varied scope of practice, a societal orientation, a lower interest in research, desire for short postgraduate training, and lower preference for medical versus social problems.

Interpretation

Demographic and attitudinal characteristics at entry into medical school predicted whether students chose a career in family medicine.The number of physicians per capita in both Canada and the United States has declined, and this decline is expected to continue. Canada has already experienced a drop of 5.1% in the physician-to-population ratio from a peak in 2000, and in the United States a shortage of up to 200 000 physicians, or 20% of the needed workforce, is predicted to occur by 2025.^1,2 Combined with a growing elderly population and decreasing physician-hours,^3,4 this reduction in the physician-to-population ratio is expected to have implications for the health care systems of both countries. Therefore, health resource planners likely will be looking to expand the role of primary care, and of family medicine in particular.^5–8 To support such an expansion, a commensurate increase in the numbers of domestically trained family physicians will be required. But with as few as 25% (in 2003)⁹ of Canadian medical graduates choosing family medicine as their top career choice in the residency match, it is unlikely the health care system will be able to supply adequate numbers of primary care physicians.In most countries, the number and the distribution of specialties of physicians are determined by numerous factors, including government policies, training opportunities, immigration and emigration of providers, sex and age distribution of providers, and remuneration incentives and disincentives.^10–17 In many medical systems, the career interests of students also have a substantial steering effect on the distribution and number of available physicians.^18,19The purpose of this study was to follow a large cohort of Canadian medical students from school entry through exit to examine how their career aspirations changed over time and to identify, using multiple logistic regression analysis, the variables at entry into medical school that predict a career choice of family medicine at graduation.     

The joy of a career in cell biology

Science is a career where you do what you love everyday. Our science is built on the shoulders of those who came before us, and in turn we provide shoulders for our students and colleagues to build upon. Of course, seeing the seeds of ideas that we plant bear fruit as interesting science is why I love being a scientist. Looking back it also has been a particularly gratifying challenge to mentor members of the younger generation in building their careers.     

Dentistry as a prospective career choice in india

Career choice is a complex decision in a student''s life. The opportunity to participate in dental education in many countries, especially in the developing ones, is limited to a small percentage of the community. There is a wide range of options for students to choose as a career in general family, gender, personal interest; outcome expectancies can affect the decision in choosing it. Many studies showed that many individuals find themselves in occupations not really knowing why they made that particular decision. The changing nature of the dental workforce and the need to retain the services of future members has made it important to understand why current dental students have chosen dentistry as their career. However, the choice of dentistry becomes forceful at times by peer pressure, cultural thrust or inability to procure medicine. It is of interest to evaluate dentistry as a prospective career choice in India. The participants answered a questionnaire based online survey and the results were collected and analysed statistically. Analyses of data from the survey shows that majority (36.72%) of students had chosen dentistry as a career choice having missed entry or selection into medicine.
