RESUMO

The Department of Chemistry and Biochemistry at St. Mary's College of Maryland has scaffolded collaboration skills throughout the Biochemistry curriculum and developed several assessment tools to evaluate these skills. Biochemistry I and II have used team contracts at the beginning of extensive team projects where students identify their strengths, review expectations, and plan for group communication. At the conclusion of each project, each student assesses their own contributions and team members for various parts of the project. A common collaboration rubric was also applied in Biochemistry I and II as well as in two other courses, General Chemistry II Lab and Physical Chemistry I Lab, for students to evaluate themself and team members using the following subcategories: quality of work, commitment, leadership, communication, and analysis. In Biochemistry I and II, we used this rubric for multiple assignments that are part of the projects in the lecture courses. In the General Chemistry II Lab, we provided elements of this rubric within an evaluation form that reflects these collaboration attributes after each lab experience, so students can assess and report privately on their experiences as part of their collaboration grade for the course. A similar collaboration rubric is completed by students for each team-based laboratory within Physical Chemistry I. We also demonstrate different ways that instructors can use the data from these assessment tools. In our department, we are using these tools to frame the importance of collaboration skills and collecting data to inform our teaching of these skills. Preliminary data suggest that our curriculum is successfully teaching students how to be good collaborators.

RESUMO

There are numerous opportunities for shared decision-making (SDM) in cystic fibrosis (CF) care, yet little is known about patients' SDM experiences. This study evaluated SDM across 159 CF care programs (4024 participants) in the United States. Shared decision-making was assessed using the patient-reported collaboRATE measure, which was included in the CF Foundation's Patient and Family Experience of Care Survey over 18 months. Overall, 69% of respondents reported experiencing SDM. Respondents at pediatric programs were more likely to experience SDM than those at adult programs (72% vs 67%, P < .001). Multivariable logistic regression analyses showed a relationship between SDM and patient age, whereby SDM was less likely to occur with patients aged 18 to 24 years, compared to some younger and older age groups (P = .02-<.001). Shared decision-making was more likely to occur at pediatric programs when patients had better general health (P = .02-<.01), and at pediatric and adult programs when patients had better mental health (P = .02-<.001). Disparities in SDM experiences highlight a need to improve decision-making processes in CF care. Interventions tailored for improving SDM among specific patient populations may be particularly advantageous.

RESUMO

This article describes a synergistic two-semester writing sequence for biochemistry courses. In the first semester, students select a putative protein and are tasked with researching their protein largely through bioinformatics resources. In the second semester, students develop original ideas and present them in the form of a research grant proposal. Both projects involve multiple drafts and peer review. The complementarity of the projects increases student exposure to bioinformatics and literature resources, fosters higher-order thinking skills, and develops teamwork and communication skills. Student feedback and responses on perception surveys demonstrated that the students viewed both projects as favorable learning experiences.

RESUMO

Combretastatin A4 is a stilbenoid tubulin binding mitotic inhibitor whose conformation greatly influences its potency, making it an excellent candidate for adaptation as a photoactivatable tool. Herein we report a novel synthesis, the facile isomerization with commercial grade equipment, and biological activity of azo-combretastatin A4 in vitro and in human cancer cells. Photoisomerized azo-combretestatin A4 is at least 200-fold more potent in cellular culture, making it a promising phototherapeutic and biomedical research tool.

RESUMO

Recognizing the increasingly integrative nature of the molecular life sciences, the American Society for Biochemistry and Molecular Biology (ASBMB) recommends that Biochemistry and Molecular Biology (BMB) programs develop curricula based on concepts, content, topics, and expected student outcomes, rather than courses. To that end, ASBMB conducted a series of regional workshops to build a BMB Concept Inventory containing validated assessment tools, based on foundational and discipline-specific knowledge and essential skills, for the community to use. A culminating activity, which integrates the educational experience, is often part of undergraduate molecular life science programs. These "capstone" experiences are commonly defined as an attempt to measure student ability to synthesize and integrate acquired knowledge. However, the format, implementation, and approach to outcome assessment of these experiences are quite varied across the nation. Here we report the results of a nation-wide survey on BMB capstone experiences and discuss this in the context of published reports about capstones and the findings of the workshops driving the development of the BMB Concept Inventory. Both the survey results and the published reports reveal that, although capstone practices do vary, certain formats for the experience are used more frequently and similarities in learning objectives were identified. The use of rubrics to measure student learning is also regularly reported, but details about these assessment instruments are sparse in the literature and were not a focus of our survey. Finally, we outline commonalities in the current practice of capstones and suggest the next steps needed to elucidate best practices.

RESUMO

Ectopic accumulation of lipid droplets in non-adipose tissues correlates with the degree of insulin resistance in these tissues. Emerging evidence indicates that lipid droplets are specialized organelles that participate in lipid metabolism and intracellular trafficking. These properties are thought to derive from the lipid droplet-associated PAT protein family (perilipin, ADFP, and Tip47). The functions of the ubiquitously distributed adipose differentiation-related protein (ADFP) and Tip47 remain unknown. To evaluate the roles of ADFP and Tip47 in lipid biogenesis and metabolism, ADFP null and wild type (wt) clonal cell lines were established from ADFP null and wt mice, respectively. In ADFP null cells, Tip47 was identified as the sole lipid droplet-associated protein from the PAT family by mass spectroscopy, which was further confirmed by immunoblotting and immunocytochemistry. Following incubation with oleic acid, ADFP null cells were able to form lipid droplets to the same extent as wt cells. No statistical differences between the two cell types were observed in NEFA uptake or lipolysis. Small interference RNAs (siRNAs) against Tip47 were found to down-regulate protein levels for Tip47 by 85%. ADFP null cells treated with Tip47 siRNA retained the ability to form lipid droplets but to a lesser extent and shunted the utilization of exogenously added NEFA from triglycerides to phospholipids. These data support the hypothesis that Tip47 plays an important role in lipid metabolism. Tip47 and ADFP in peripheral tissues may play a critical role in regulating the formation and turnover, and hence metabolic consequences, of ectopic fat.

RESUMO

Based on data developed with the use of isolated lipid droplets from neonatal rat lung lipofibroblasts, we speculated previously that the droplet coat protein, adipose differentiation-related protein (ADFP), mediated the transfer of lipids into type 2 lung epithelial cells for the production of surfactant phospholipids. The present studies were designed to test the role of ADFP in this transfer with the use of ADFP-coated lipid droplets from CHO fibroblast cells and a cultured human lung epithelial cell line. We found no role for ADFP in the lipid transfer and conclude that a lipase associated with the lipid droplets hydrolyzes their core triacylglycerols, releasing fatty acids that are taken up by the epithelial cells.
