This brief report provides an overview of lessons learned through evaluation of the first five years of the NIA-funded South Carolina-Advancing Diversity in Aging Research (SC-ADAR) undergraduate ...program, whose goal is to increase the number of qualified underrepresented minority (URM) students who pursue scientific graduate studies in programs focusing on medicine, science, technology, engineering, and mathematics and aging. Partnering with five Historically Black Colleges and Universities in South Carolina, we implemented a research training approach that included two consecutive summers of research training in a University of South Carolina faculty laboratory, as part of a comprehensive 24-month research education program. In addition to the mentored research experience in a laboratory, students had coursework in the biology of aging and social gerontology, with additional workshops tailored to emergent student needs including basic academic skills development, work-life management skills, reflective social experiences, and enhanced support in the transition from undergraduate to graduate school. We provide an overview of lessons learned throughout the early program period, and a description of the iterative changes we made in the program in response to this learning, all of which have been incorporated into the existing SC-ADAR program.
This paper presents reflections on mentorship from scientists and mentors of the National Institute on Aging (NIA)-funded Carolina Center on Alzheimer’s Disease and Minority Research (CCADMR). Using ...a network approach to mentoring, this program aims to increase the pipeline of underrepresented minority (URM) scientists studying Alzheimer’s disease (AD) disparities. Six mentors and five scientists participated in interviews. Thematic analysis identified recurring themes; transcripts of mentors and scientists were compared. Most common thematic categories identified by mentors included experience interacting with scientists, goals as a mentor, recruitment of underrepresented minorities, scientists’ challenges, and programmatic qualities. The most mentioned categories by scientists were challenges, seminars, working with mentors, career development, and project experience. The CCADMR will use findings to enhance the experience and training methods for future grant years. Results can benefit other training programs focused on aging and AD.
Like cancer, Alzheimer's disease and related dementias (ADRD) comprise a global health burden that can benefit tremendously from the power of disease registry data. With an aging population, the ...incidence, treatment, and mortality from ADRD is increasing and changing rapidly. In the same way that current cancer registries work toward prevention and control, so do ADRD registries. ADRD registries maintain a comprehensive and accurate registry of ADRD within their state, provide disease prevalence estimates to enable better planning for social and medical services, identify differences in disease prevalence among demographic groups, help those who care for individuals with ADRD, and foster research into risk factors for ADRD. ADRD registries offer a unique opportunity to conduct high-impact, scientifically rigorous research efficiently. As research on and development of ADRD treatments continue to be a priority, such registries can be powerful tools for conducting observational studies of the disease. This perspectives piece examines how established cancer registries can inform ADRD registries' impact on public health surveillance, research, and intervention, and inform and engage policymakers.
Selected members of plant pathogenesis-related and seed storage proteins represent specific groups of proteins with potential characteristics of allergens. Efforts to understand the mechanism by ...which pathogenesis-related proteins mediate a broad cross-reactivity in pollen-plant food allergens are still limited. In this study, computational biology approach was used to reveal specific structural implications and conservation of different epitopes from members of Bet v 1 and nsLTP protein families mediating cross-reactivity between pollen and food (fruits, vegetables, legumes, and nut/seeds) allergens. A commonly shared epitope conservation was found among all pollen and food Bet v 1 and nsLTP protein families, respectively. However, other allergenic epitopes were also specifically detected in each family. The implication of these conserved epitopes in a broad cross-reactivity for allergy clinical trials is here discussed.
Genomic DNA extraction protocols generally require the use of expensive and hazardous reagents necessary for decontamination of phenolic compounds from the extracts. In addition, they are lengthy, ...hindering large-scale sample extractions necessary for high-throughput analyses. Here we describe a simple, time and cost-efficient method for genomic DNA extraction from insects. The extracted DNA was successfully used in a Polymerase Chain Reaction (PCR), making it suitable for automation for large-scale genetic analysis and barcoding studies. The protocol employs a single purification step to remove polysaccharides and other contaminating compounds using a non-hazardous reagent buffer. In addition, we conducted a bioinformatics database analysis as proof of concept for the efficiency of the DNA extraction protocol by using universal barcoding primers specific for cytochrome c oxidase I gene to identify different arthropod specimens through Barcode of Life Database (BOLD) database search. The usefulness of this protocol in various molecular biology and biodiversity studies is further discussed.
Twenty-two cassava genotypes and eight controls were evaluated in two cropping seasons for resistance to cassava mosaic disease (CMD) at the International Institute of Tropical Agriculture (IITA) ...fields, located at different ecozones of Nigeria. Disease incidence (DI) and index of symptom severity data were obtained monthly at each location and genotype. Symptomatic leaves were also collected during evaluation at each location, and virus was indexed by amplification in polymerase chain reaction. Significant differences within and across locations were observed in the reactions of cassava genotypes to CMD. DI across cassava genotypes was significantly (p = 0.05) highest in the Ibadan (22.6%), followed by Onne (19.3%). Generally, plants of clones 96/0860, 96/1439, 96/0160, 96/1089A, 96/1632, 96/1613, 96/1708, 96/0191, 96/0249 and 96/1565 had significantly lower values of DI in each location. African cassava mosaic virus in single infection was the predominant causal agent of CMD in IITA experimental fields under study.
The annual National Conference on Health Disparities (NCHD) was launched in 2000. It unites health professionals, researchers, community leaders, and government officials, and is a catalyzing force ...in developing policies, research interventions, and programs that address prevention, social determinants, health disparities, and health equity. The NCHD Student Research Forum (SRF) was established in 2011 at the Medical University of South Carolina to build high-quality biomedical research presentation capacity in primarily underrepresented undergraduate and graduate/professional students. This paper describes the unique research training and professional development aspects of the NCHD SRF. These include guidance in abstract development, a webinar on presentation techniques and methods, a vibrant student-centric conference, and professional development workshops on finding a mentor and locating scholarship/fellowship funding, networking, and strategies for handling ethical issues in research with mentors. Between 2011 and 2018, 400 undergraduate and graduate/professional students participated in the NCHD SRF. Most students were women (80.5%). Approximately half were African American or black (52.3%), 18.0% were white, and 21.3% were of Hispanic/Latinx ethnicity. The NCHD SRF is unique in several ways. First, it provides detailed instructions on developing a scientific abstract, including content area examples. Second, it establishes a mandatory pre-conference training webinar demonstrating how to prepare a scientific poster. Third, it works with the research mentors, faculty advisors, department chairs, and deans to help identify potential sources of travel funding for students with accepted abstracts. These features make the NCHD SRF different from many other conferences focused on students’ scientific presentations.
