- Abstract
Background: Pharmacy deserts represent areas where residents face notable challenges to accessing pharmacies. North Carolina (NC) presents an intriguing case study due to its diverse geographic landscape yet lacks extensive research regarding its pharmacy deserts., Objectives: This study aims to map pharmacy deserts in NC using pharmacy location and social determinants of health (SDOH) data measured using the social vulnerability index (SVI) and descriptively characterize health care utilization statistics for University of North Carolina (UNC) Health's catchment population., Methods: Pharmacy location data was compiled from the NC Board of Pharmacy. Pharmacy deserts were defined based on SVI > 0.75 and distance thresholds aligned to United States Department of Agriculture standards. Residential characteristics were retrieved from PolicyMap and Social Explorer databases. UNC Health patient utilization data were collected by UNC Pharmacy Data Analytics group for 3 NC counties., Results: Two thousand and two NC pharmacies met inclusion criteria. 17.2% urban tracts (1.3M residents) and 4.25% rural tracts (0.14M residents) were identified as pharmacy deserts (adj. P < 0.001). Those residing in deserts had significantly less internet access, annual medical cost per capita, and access to homeless relief services as well as significantly higher food insecurity rates and Medicare cost per capita (adj. P < 0.001). UNC-specific health care utilization statistics for the 3 assessed counties were all poorer in deserts compared to nondeserts within the same counties (P > 0.05)., Conclusion: A geospatial map with the location of pharmacy deserts in NC was created to highlight differences in patient health care utilization, affecting rural and urban areas. By incorporating SDOH predictors, this study provides a more nuanced map of NC pharmacy deserts compared to reviewing distance to pharmacies alone. Higher rates of emergency department and inpatient visits in counties with more residents in pharmacy deserts suggests potential health outcomes associated with limited pharmacy access., Competing Interests: Disclosure The authors declare no relevant conflicts of interest or financial relationships., (Published by Elsevier Inc.)

- Abstract
Recombinant rabies virus (RV) vaccine strain-based vectors have been successfully developed as vaccines against other viral diseases (J. P. McGettigan et al., J. Virol. 75:4430-4434, 2001; McGettigan et al., J. Virol. 75:8724-8732, 2001; C. A. Siler et al., Virology 292:24-34, 2002), and safety concerns have recently been addressed (McGettigan et al., J. Virol. 77:237-244, 2003). However, size limitations of the vectors may restrict their use for development of vaccine applications that require the expression of large and multiple foreign antigens. Here we describe a new RV-based vaccine vehicle expressing 4.4 kb of the human immunodeficiency virus type 1 (HIV-1) Gag-Pol precursor Pr160. Our results indicate that Pr160 is expressed and processed, as demonstrated by immunostaining and Western blotting. Electron microscopy studies showed both immature and mature HIV-1 virus-like particles (VLPs), indicating that the expressed HIV-1 Gag Pr55 precursor was processed properly by the HIV-1 protease. A functional assay also confirmed the cleavage and functional expression of the HIV-1 reverse transcriptase (RT) from the modified RV genome. In the next step, we constructed and recovered a new RV vaccine strain-based vector expressing a chimeric HIV-1(89.6P) RV envelope protein from an additional RV transcription unit located between the RV nucleoprotein (N) and phosphoprotein (P) in addition to HIV-1 Pr160. The 2.2-kb chimeric HIV-1/RV envelope protein is composed of the HIV-1 Env ectodomain (ED) and transmembrane domain (TD) fused to RV glycoprotein (G) cytoplasmic domain (CD), which is required for efficient incorporation of HIV-1 Env into RV particles. Of note, the expression of both HIV-1 Env and HIV-1 Pr160 resulted in an increase in the rhabdoviral genome of >55%. Both rhabdovirus-expressed HIV-1 precursor proteins were functional, as indicated by RT activity and Env-based fusion assays. These findings demonstrate that both multiple and very large foreign genes can be effectively expressed by RV-based vectors. This research opens up the possibility for the further improvement of rhabdovirus-based HIV-1 vaccines and their use to express large foreign proteins, perhaps from multiple human pathogens.

- Abstract
The interaction of various compounds with sigma binding sites was examined in membranes prepared from whole guinea pig brain. Whereas [3H](+)-3-(3-hydroxyphenyl)-N-(1-propyl)piperidine labeled a single population of binding sites exhibiting a Kd of 43 nM, [3H]1,3-di-o-tolylguanidine bound to two sites having Kds of 35 and 212 nM, and to a greater maximum number of sites than [3H](+)-3-(3-hydroxyphenyl)-N-(1-propyl)piperidine. Haloperidol, 1,3-di-o-tolylguanidine, BMY 14802, and (-)-pentazocine each displayed nearly equal affinity for binding sites labeled by [3H](+)-3-(3-hydroxyphenyl)-N-(1-propyl)piperidine and [3H]1,3-di-o-tolylguanidine, whereas (+)-3-(3-hydroxyphenyl)-N-(1-propyl)piperidine was 3 times more potent in inhibiting [3H](+)-3-(3-hydroxyphenyl)-N-(1-propyl)piperidine than [3H]1,3-di-o-tolylguanidine binding. In contrast, (+)-SKF 10,047, (+)-cyclazocine and (+)-pentazocine exhibited more than 9-fold higher affinity for [3H](+)-3-(3-hydroxyphenyl)-N-(1-propyl)piperidine than [3H]1,3-di-o-tolylguanidine binding sites. Dextromethorphan was 15-fold more potent against [3H](+)-3-(3-hydroxyphenyl)-N-(1-propyl)piperidine than [3H]1,3-di-o-tolylguanidine, inhibited [3H](+)-3-(3-hydroxyphenyl)-N-(1-propyl)piperidine binding in a biphasic manner, and inhibited [3H]haloperidol and [3H](+)-SKF 10,047 binding with potencies similar to those obtained against [3H]1,3-di-o-tolylguanidine and [3H](+)-3-(3-hydroxyphenyl)-N-(1-propyl)piperidine, respectively. Phenytoin increased [3H](+)-3-(3-hydroxyphenyl)-N-(1-propyl)piperidine and [3H](+)-SKF 10,047 binding, but did not enhance [3H]1,3-di-o-tolylguanidine or [3H]haloperidol binding. However, the potency of dextromethorphan to inhibit [3H]1,3-di-o-tolylguanidine binding was increased in the presence of phenytoin.(ABSTRACT TRUNCATED AT 250 WORDS)
