Tachia - an anti-malarial plant from Amazonas
• herbal against malaria• Member of Gentianaceae• Many gentians have anti-inflammatory,
anti-fungal, and anti-fever properties; used worldwide.
• Other gentians used in South America: Chelonanthus (Irlbachia) alata and Potalia.
• Which Tachia species is it and which is the active compound?
Tachiaproject
• Objectives: Pharmaceutical potential of Tachia, taxonomy, cultivation, distribution, and evolution. Tri-lingual manual, information on the internet, scientific papers.
• Results: the Tachia plant around Manaus is a different species than reported earlier.
• Currently supported by funding from Brazil and US: CNPq, BioAmazonia/BASA/FEPAD, National Science Foundation, and Rutgers Research Council

Possibilities
A formal agreement could facilitate:• Mutual research interests - many research areas,
interdisciplinary and international collaboration• International graduate student exchange• Competitive collaborative grant proposals• Exchange of technology and research results• Training in new techniques• Bilateral access to expensive equipment, biological
materials, and information resources

Induction of Caffeine Synthesis –A Possible Defense Response to Pathogen Infection in Cocoa
Dr. Tom GianfagnaResearch Project
• Young flush leaves produce caffeine in response to infection
• Salicylic acid is the caffeine inducing hormone
• Leaves 3-4 cm appear to be maximally responsive to induction
• Induction of caffeine synthesis is systemic within the flush leaves
• Resistant types derived from SCA 06 produce caffeine in response to WB infection, sensitive types do not

Dr. Daniel HoffmanDept. of Nutritional Science
• Human health, diabetes, obesity, body composition
• Nutrition in children• Food sources, influence of
supermarkets• Organized a clinical nutrition
research center in São Paulo, Brazil, to study the metabolism and food intake of children living in the favelas.
Nutrition among children and how it affects health later in life
Dr. Daniel Hoffman Research Project
• Does undernutrition during childhood increase the risk for obesity and diabetes?
• Do children who are undernourished early in life distribute fat in unhealthy patterns compared to healthy children?
• Is the influx of supermarkets in transitional economies improving diet or promoting excess caloric intake?
