State of the Science and the Intraductal Approach for Breast Cancer: Proceedings Summary of The Sixth International Symposium on the Intraductal Approach To Breast Cancer Santa Monica, California, 19–21 February 2009
Researchers are using the intraductal approach to advance breast cancer risk assessment, prevention, diagnosis, and treatment. Procedures and technologies that can access and interrogate the ductal-alveolar systems include nipple aspiration, ductal lavage and ductoscopy. Ductoscopic papillectomy, ductoscopic margin evaluation, and intraductal therapy are considered promising investigational and innovative treatments. These techniques are used to explore the biology of the normal breast; collect and analyze breast fluid and cells to identify biomarkers that can be used in breast cancer detection and risk assessment; and to identify new ways to find and administer therapeutic and/or preventive agents to the breast tissue. This report summarizes the latest research findings in these areas, presented at The 6th International Symposium on the Intraductal Approach to Breast Cancer in 2009
Creating a waste free tomorrow: Assessing waste literacy and behaviour change in grade 5 students
There is a growing necessity to implement awareness campaigns to inform behaviour change toward more sustainable consumption of plastic products, and a need to train science students in outreach communication and teaching. We’ve developed a school program to improve scientific and waste literacy among elementary students. Graduate and Undergraduate student volunteers co-created lesson plans exploring our relationship with plastics: 1. Plastic Cycle, 2. Watersheds and their Relationship to Litter, 3. Impacts of Plastic on Ecosystems, and 4. Solutions to Plastic Pollution. The lessons include direct connections to research by members of our team, all early-career scientists with a focus on understanding the sources, fate, effects, and mitigation of plastic pollution. Using a peer-to-peer framework, lessons are delivered by university student instructors, offering learning and mentoring opportunities across many levels of education. To reduce barriers of accessibility, classroom visits are offered at no charge. To assess the effectiveness of these lesson plans, we are studying how the lessons impact knowledge, attitudes, and self-reported behaviours toward aquatic litter and plastic pollution in participating children. For this study, we administered short paper questionnaires pre-and post-participation in the school program from October 2021 to May 2023. The questionnaire was administered before the first class and then several weeks later. Results will be shared at this conference which can inform strategies to engage children in the topic of plastic pollution in aquatic ecosystems. We\u27ll also share our experience creating this program with the post-secondary students. This research was approved by our institutional research ethics board
The Fourth International Symposium on the Intraductal Approach to Breast Cancer, Santa Barbara, California, 10–13 March 2005
Intraductal approaches encompass procedures and technologies that are designed to access and interrogate the ductal–alveolar systems of the human breast, and include nipple aspiration, ductal lavage, random periareolar fine needle aspiration, and ductoscopy. These approaches are being used to collect and analyze fluids and cells to develop methods for breast cancer detection and risk assessment; to introduce imaging technologies to explore the mammary tree for abnormalities; to administer therapeutic and/or preventive agents directly to the breast tissue; and to explore the biology of the normal mammary gland. The latest research findings in these areas, presented at The 4th International Symposium on the Intraductal Approach to Breast Cancer in 2005, are summarized in this report
Plastic Particles in Silverside (Stolephorus heterolobus) Collected at Paotere Fish Market, Makassar
Initial research of Unhas dan UCD collaborationPlastics represent the latest contaminant in the marine environment. Although plastics without doubt represent a uniquely valuable material particularly in construction, packaging and fishing gear applications. Current research on plastic debris in digestive tract content of pelagic fish is part of ongoing collaboration between University of Hasanuddin and University of California at Davis. Locally caught and consumed Silverside (Stolephorus heterolobus) or widely known as anchovies has been the subject on this studies. Four out of 10 fish investigated were found to contained plastic particles in their digestive tract. This is the first work on plastic debris in fish gut ever conducted in the region, which is in accordance to previous works on plastics debris elsewhere and will be further discussed for their possible effects, both on food safety and human toxicology
Anthropogenic debris in seafood: Plastic debris and fibers from textiles in fish and bivalves sold for human consumption.
The ubiquity of anthropogenic debris in hundreds of species of wildlife and the toxicity of chemicals associated with it has begun to raise concerns regarding the presence of anthropogenic debris in seafood. We assessed the presence of anthropogenic debris in fishes and shellfish on sale for human consumption. We sampled from markets in Makassar, Indonesia, and from California, USA. All fish and shellfish were identified to species where possible. Anthropogenic debris was extracted from the digestive tracts of fish and whole shellfish using a 10% KOH solution and quantified under a dissecting microscope. In Indonesia, anthropogenic debris was found in 28% of individual fish and in 55% of all species. Similarly, in the USA, anthropogenic debris was found in 25% of individual fish and in 67% of all species. Anthropogenic debris was also found in 33% of individual shellfish sampled. All of the anthropogenic debris recovered from fish in Indonesia was plastic, whereas anthropogenic debris recovered from fish in the USA was primarily fibers. Variations in debris types likely reflect different sources and waste management strategies between countries. We report some of the first findings of plastic debris in fishes directly sold for human consumption raising concerns regarding human health
