Intranasal naloxone delivery is an alternative to intravenous naloxone for opioid overdoses ☆
Abstract Introduction: This study proposes that intranasal (IN) naloxone administration is preferable to intravenous (IV) naloxone by emergency medical services for opioid overdoses. Our study attempts to establish that IN naloxone is as effective as IV naloxone but without the risk of needle exposure. We also attempt to validate the use of the Glasgow Coma Scale (GCS) in opioid intoxication. Methods: A retrospective chart review of prehospital advanced life support patients was performed on confirmed opioid overdose patients. Initial and final unassisted respiratory rates (RR) and GCS, recorded by paramedics, were used as indicators of naloxone effectiveness. The median changes in RR and GCS were determined. Results: Three hundred forty-four patients who received naloxone by paramedics from January 1, 2005, until December 31, 2007, were evaluated. Of confirmed opioid overdoses, change in RR was 6 for the IV group and 4 for the IN group (P = .08). Change in GCS was 4 for the IV group and 3 for the IN group (P = .19). Correlations between RR and GCS for initial, final, and change were significant at the 0.01 level (ρ = 0.577, 0.462, 0.568, respectively)
Retinal Venule Coverage by Pericytes Decreases in Multiparous Mice in a Time-Dependent Manner Post-Delivery
Structural changes in the retinal vasculature have been linked to increased cardiovascular risks and also change as a function of age. Because multiparity has been associated with poorer cardiovascular health scores, we hypothesized that changes in retinal vascular caliber would be observed in multiparous, compared to nulliparous, females and retired breeder males. Age-matched nulliparous (n = 6) and multiparous (n = 11, retired breeder females with 4 ± 1 litters), and male breeder (n = 7) SMA-GFP reporter mice were included for assessment of retinal vascular structure. Multiparous females had higher body mass, heart weight, and kidney weight compared to nulliparous mice, with lower kidney and higher brain weight compared to male breeders. There was no difference in number of retinal arterioles or venules, or arteriole or venule diameter among groups; however, venous pericyte density (number per venule area) decreased in multiparous vs. nulliparous mice and was negatively associated with the time since last litter and with age. Our results suggest that the time elapsed since delivery is an important factor to be considered in multiparity studies. Taken together, changes in vascular structure and potentially function, are time- and age-dependent. Ongoing and future work will determine whether structural changes are associated with functional consequences at the blood–retinal barrier

Expression, purification and crystallization of human prolylcarboxypeptidase
Crystallization of glycosylated human prolylcarboxypeptidase expressed in Chinese hamster ovary cells is described. The hexagonal crystals belong to space group R32 and diffract to 2.8 Å resolution

SNAREing immunity: the role of SNAREs in the immune system
The trafficking of molecules and membranes within cells is a prerequisite for all aspects of cellular immune functions, including the delivery and recycling of cell surface proteins, secretion of immune mediators, ingestion of pathogens and activation of lymphocytes. SNARE (soluble-N-ethylmaleimide-sensitive-factor accessory-protein receptor)-family members mediate membrane fusion during all steps of trafficking, and function in almost all aspects of innate and adaptive immune responses. Here, we provide an overview of the roles of SNAREs in immune cells, offering insight into one level at which precision and tight regulation are instilled on immune responses
