Resolving Gnetum Evolutionary History

Gnetum are non-flowering seed plants of the tropics, indigenous to South America, Africa, and Asia. This group of about 40 species is fascinating to botanists because it shares distinctive morphological characteristics with flowering plants, such as broad leaves, woody stems, and flower-like strobili. There are still questions surrounding the relationships within the genus of Gnetum. With that in mind, I focused my work on generating phylogenetic hypotheses, using two molecular data sets: a concatenation of over 60 different chloroplast genes (66,815 base pairs), and the whole chloroplast genome (128,772 base pairs). This allowed me to compare the two phylogenies and assess whether adding non-coding regions increase phylogenetic resolution. Statistical tests determined that the data were sufficient to answer questions about deep splits, and to resolve the branches within the genus. I used each of the two data sets to infer Maximum Parsimony and Maximum Likelihood phylogenetic hypotheses for 18 species of Gnetum. Confidence levels for most nodes were very high, and trees show clades consistent with biogeography. My bootstrap results suggest that the South American clade may not be the earliest diverging lineage, although statistical tests support the South American clade at the base of the Gnetum tree

Feasibility of Podcasts and City by City Analysis for Upside.FM

The objective of the project is to conduct a feasibility study for Upside, with regard to their underlying business model. We then hope to make recommendations for other cities and complementary products that can fit under the Upside umbrella

ACCISS study rationale and design: activating collaborative cancer information service support for cervical cancer screening

<p>Abstract</p> <p>Background</p> <p>High-quality cancer information resources are available but underutilized by the public. Despite greater awareness of the National Cancer Institute's Cancer Information Service among low-income African Americans and Hispanics compared with Caucasians, actual Cancer Information Service usage is lower than expected, paralleling excess cancer-related morbidity and mortality for these subgroups. The proposed research examines how to connect the Cancer Information Service to low-income African-American and Hispanic women and their health care providers. The study will examine whether targeted physician mailing to women scheduled for colposcopy to follow up an abnormal Pap test can increase calls to the Cancer Information Service, enhance appropriate medical follow-up, and improve satisfaction with provider-patient communication.</p> <p>Methods/Design</p> <p>The study will be conducted in two clinics in ethnically diverse low-income communities in Chicago. During the formative phase, patients and providers will provide input regarding materials planned for use in the experimental phase of the study. The experimental phase will use a two-group prospective randomized controlled trial design. African American and Hispanic women with an abnormal Pap test will be randomized to Usual Care (routine colposcopy reminder letter) or Intervention (reminder plus provider recommendation to call the Cancer Information Service and sample questions to ask). Primary outcomes will be: 1) calls to the Cancer Information Service; 2) timely medical follow-up, operationalized by whether the patient keeps her colposcopy appointment within six months of the abnormal Pap; and 3) patient satisfaction with provider-patient communication at follow-up.</p> <p>Discussion</p> <p>The study examines the effectiveness of a feasible, sustainable, and culturally sensitive strategy to increase awareness and use of the Cancer Information Service among an underserved population. The goal of linking a public service (the Cancer Information Service) with real-life settings of practice (the clinics), and considering input from patients, providers, and Cancer Information Service staff, is to ensure that the intervention, if proven effective, can be incorporated into existing care systems and sustained. The approach to study design and planning is aimed at bridging the gap between research and practice/service.</p> <p>Trial Registration</p> <p>NCT00873288</p
