Exploring Criteria for the Translation of Traditional Knowledge Within Contemporary Clinical Practice, Research, Policy, and Education: A Stakeholder Forum.

Background: The 2018 Declaration of Astana identifies traditional knowledge (TK) as one of the drivers for strengthening primary health care systems through the use of technology (traditional medicines) and knowledge and capacity building (traditional practitioners). While TK underpins both traditional practice and the use of traditional medicines, facilitating the use of TK in contemporary health care systems has been difficult to achieve. The aim of this study was to identify key factors related to the translation of TK into contemporary settings to help establish tools to support the knowledge translation process. Methods: This study used World Café methodology to collect the observations, ideas, and perspectives of experts who use TK in their practice. These experts (n = 9) were from a variety of contexts, including clinical practice, research, education, policy, and consumer advocacy, participated in the 1-day event. Data were collected into NVivo 12 software and analyzed using inductive-deductive thematic analysis. Results: Thematic analysis identified five themes: the need to define the elements required for critical evaluation of sources of TK as evidence, the importance of applying a tradition-centric lens when translating TK for contemporary use, the need to bridge gaps between TK and its contemporary applications, the value of critically evaluating the TK translation process itself, and the recognition of traditions as living systems. Taken together, the themes showed holistic interpretation of the translation process that incorporates critical analysis of the TK itself and accountable, transparent, and ethical processes of translation that consider safety, socioeconomical and intellectual property impacts of TK in contemporary use. Conclusions: Stakeholders identified TK as a valid and important source of evidence that should guide practice in a range of contemporary settings (e.g., policy and clinical practice), and outlined important consideration for critiquing, evaluating, communicating, and using TK within these settings.

Assessment of atrazine toxicity to the estuarine phytoplankter, Dunaliella tertiolecta (Chlorophyta), under varying nutrient conditions.

Anthropogenic inputs of chemical environmental contaminants are frequently associated with developing harmful algal blooms, but little is known about how estuarine phytoplankton assemblages respond to multiple, co-occurring chemical stressors in chronically disturbed habitats. The goals of this research were to establish a robust protocol for testing the effects of atrazine on estuarine phytoplankton, and then to use that protocol to compare the effects of atrazine exposure with and without nutrient enrichment on a cosmopolitan estuarine/marine alga, Dunaliella tertiolecta (Chlorophyta). Atrazine sensitivity in nutrient-replete media (96-h growth inhibition [Formula: see text]) was 159.16 µg l-1, but sensitivity was influenced by exposure duration, and inhibitory effects of herbicide on algal growth decreased under imbalanced nutrient regimes and low nitrogen and phosphorus supplies. These findings advance knowledge about how nutrient regimes and herbicides interact to control estuarine phytoplankton population dynamics.

Reference ranges for hemolymph chemistries from Elliptio complanata of North Carolina.

Hemolymph chemistries may be useful nonlethal measures of bivalve health. The prognostic value of hemolymph, however, depends on a comparison of chemistry results to reference ranges from healthy individuals. Currently, knowledge of expected hemolymph values in healthy and unhealthy freshwater mussels is extremely limited. The purpose of this study was to develop a set of reference ranges for clinical evaluation of hemolymph from a freshwater mussel species common to southeastern USA. We collected hemolymph from 380 Elliptio complanata from 19 apparently healthy populations from northwest of Raleigh, North Carolina, during May through July 2001. We present reference ranges for hemolymph parameters ammonia, glucose, calcium, magnesium, phosphorus, aspartate aminotransferase (AST), bicarbonate, protein and cell count, and for tissue glycogen. We compare the subpopulations of mussels from regions with an agricultural riparian buffer to those surrounded predominantly by forested lands. We further present correlations noted between hemolymph chemistries and physical or physiologic parameters. The only statistically significant differences between populations contiguous to agricultural and forested lands were in hemolymph calcium and glucose concentrations. Other statistically significant correlations identified were between gravidity and hemolymph protein concentration and tissue glycogen content, as well as between gravidity and parasite burden, and between shell length and hemolymph glucose, AST, calcium and bicarbonate concentrations. The results of this study will aid the interpretation of health measures from populations of E. complanata of similar geographic and seasonal origin.

Charting the protein complexome in yeast by mass spectrometry.

It has become evident over the past few years that many complex cellular processes, including control of the cell cycle and ubiquitin-dependent proteolysis, are carried out by sophisticated multisubunit protein machines that are dynamic in abundance, post-translational modification state, and composition. To understand better the nature of the macromolecular assemblages that carry out the cell cycle and ubiquitin-dependent proteolysis, we have used mass spectrometry extensively over the past few years to characterize both the composition of various protein complexes and the modification states of their subunits. In this article we review some of our recent efforts, and describe a promising new approach for using mass spectrometry to dissect protein interaction networks.
