In vivo scanning laser fundus and high-resolution OCT imaging of retinal ganglion cell injury in a non-human primate model with an activatable fluorescent-labeled TAT peptide probe.

The optical imaging agent TcapQ488 has enabled imaging of retinal ganglion cell (RGC) injury in vivo in rodents and has potential as an effective diagnostic probe for early detection and intervention monitoring in glaucoma patients. In the present study, we investigated TcapQ488 in non-human primates (NHPs) to identify labeling efficacy and early signals of injured RGC, to determine species-dependent changes in RGC probe uptake and clearance, and to determine dose-limiting toxicities. Doses of 3, 6, and 12 nmol of TcapQ488 were delivered intravitreally to normal healthy NHP eyes and eyes that had undergone hemiretinal endodiathermy axotomy (HEA) in the inferior retina.

A dual-purpose humanized mouse model for testing antiviral strategies against both SIV and HIV.

Nonhuman primate (NHP) models employing simian/simian-human immunodeficiency viruses (SIV/SHIVs) played a major role in the study of HIV pathogenesis, latency, and cure studies in a preclinical setting. However, it took many years to arrive at the current effective triple drug ARV regimen against SIV due to the genetic differences with that of HIVs. Since new combinations of drugs will be used in the evolving HIV cure studies, a small animal model would be ideal to determine their efficacy against the commonly used SIVs such as SIVmac239 to triage ineffective drugs prior to their application in NHPs.

Warm temperature perceived at the vegetative stage affects progeny seed germination in natural accessions of Arabidopsis thaliana.

Temperatures perceived early in the life cycle of mother plants can affect the germination of the offspring seeds. In Arabidopsis thaliana, vernalisation-insensitive mutants showed altered germination response to elevated maternal temperature, hence revealing a strong genetic determinism. However, the genetic control of this maternal effect and its prevalence across natural populations remain unclear.

Core Content, Competencies, and Accreditation in US Global Health Fellowships: A Survey of Leaders' Perspectives.

The number of global health (GH) fellowships in the United States has increased over the past two decades. However, there are currently no standard requirements, shared core content, or widespread systems of accreditation. With the growth in programs, it is appropriate to consider these issues.

Development of a Refugee Health Research Agenda in North America.

The lack of a cohesive, stakeholder-informed refugee health research agenda has been a barrier to promoting, funding, and conducting health research with refugee populations in North America. A cross-sectional study was conducted among individuals working in refugee health in North America (N = 93) to describe major domains within the field of refugee health research and to develop refugee health research priorities. Open-ended survey questions included: (1) What research topics specific to refugee research would you like to see in an international research agenda? (2) Please describe current and important gaps that you believe exist in refugee research and why? Overarching themes focused on the need for the development of research partnerships with refugee communities that are intentional, effective, and driven by the needs of refugee communities.
