Severity of Primary and Secondary Dengue Virus 1 Infections: A Hospital-Based Study in Puerto Rico, 2012-2014

1 week 1 day ago
Daniel Camprubí-Ferrer
Dengue is the most common mosquito-borne viral disease in humans. Although many dengue virus (DENV) infections are asymptomatic or produce only mild illness, DENV can occasionally cause severe and fatal disease. In this study, we compared the severity of primary and secondary DENV-1 infections among patients enrolled in a prospective, hospital-based, acute febrile illnesses surveillance system in Puerto Rico (2012-2014). Serum samples collected <7 days after symptom onset were tested for...

Surveillance for Violent Deaths - National Violent Death Reporting System, 50 States, the District of Columbia, and Puerto Rico, 2022

1 week 1 day ago
Kaitlin Forsberg
PROBLEM/CONDITION: In 2022, approximately 24,000 persons died of homicide and approximately 49,000 persons died of suicide in the United States, according to the National Vital Statistics System. This report summarizes data from CDC's National Violent Death Reporting System (NVDRS) on suicides, homicides, legal intervention deaths, unintentional firearm injury deaths, and deaths of undetermined intent that occurred in the 50 states, the District of Columbia, and Puerto Rico in 2022. Results are...

Guanosine-Based Supramolecular Particles for Enhanced Drug and Gene Delivery in Cell Culture

1 week 1 day ago
Luis M Negrón
Supramolecular hacky sacks (SHS) are a distinct class of self-assembled colloidal particles derived from guanosine (G) derivatives, engineered to support a wide range of cellular and therapeutic functions. In this study, we examine how variations in G-derivative composition influence SHS cellular uptake, intracellular trafficking, and functional efficacy. Confocal microscopy and flow cytometry reveal that uptake is highly dependent on particle composition, indicating selective engagement with...

Characterization of prokaryotic communities in Puerto Rican caves using 16S rDNA amplicon sequencing

1 week 1 day ago
Natalia Pérez-Santos
The cave ecosystems host microbial communities adapted to extreme environments. This study utilized 16S rDNA to investigate the prokaryotic diversity across seven caves in Puerto Rico's northern limestone karst belt. Microbial profiling revealed distinct subterranean communities, enhancing our understanding of cave microbiology and potential applications in environmental conservation and microbial research.

Human Networks and Data Science (HNDS)

1 week 2 days ago
Full Proposal Deadline Date: July 10, 2025
Deadline for direct submissions to Human Networks and Data Science - Core Research (HNDS-R) by permission only. Submissions with HNDS-R as secondary should follow the primary program's submission dates.

Program Guidelines: NSF 23-568

The Human Networks and Data Science program (HNDS) supports research that enhances understanding of human behavior by leveraging data and network science research across a broad range of topics. HNDS research will identify ways in which dynamic, distributed, or heterogeneous data can provide novel answers to fundamental questions about individual or group behavior. HNDS is especially interested in proposals that provide data-rich insights about human networks to support improved health, ...

Historically Black Colleges and Universities - Excellence in Research (HBCU- EiR)

1 week 2 days ago
Letter of Intent Deadline Date: July 10, 2025

Program Guidelines: NSF 23-598

The Historically Black Colleges and Universities - Excellence in Research (HBCU-EiR) program was established in response to direction provided in the Senate Commerce and Justice, Science and Related Agencies Appropriations Subcommittee Report (Senate Report 115-139), and is built on prior and continuing efforts by the National Science Foundation (NSF) to strengthen research capacity at Historically Black Colleges and Universities (HBCUs). This report provided guidance to NSF to establish the ...
