In vivo studies were carried out in New Zealand albino rabbits. A previously reported promising THC-HG ion-pair formulation was also studied in vivo.\n\nAqueous solubility and stability and in vitro
transcorneal permeability of THC-HG was enhanced significantly in the presence find more of surfactants. THC levels in the ocular tissues (except cornea) were found to be below detection limits from mineral oil, surfactant or emulsion based formulations containing THC. In contrast, micellar and ion pair based THC-HG formulations produced significantly higher total THC concentrations in the anterior ocular chamber.\n\nIn this study, although delivery of THC to the anterior chamber ocular tissues see more could be significantly increased through the prodrug and formulation approaches tested, further studies are needed to increase penetration to the back-of-the eye.”
“Context: Paraganglioma (PGL) patients and succinate dehydrogenase (SDH) gene mutation carriers at risk for PGLs have a decreased quality of life (QoL). QoL may be affected by the strategy an individual uses when dealing with a stressful situation, ie, specific coping styles. Understanding the various approaches to coping may allow the development
of targeted interventions to improve patient QoL.\n\nObjective: The objective of the study was to assess coping styles in PGL patients and SDH mutation carriers.\n\nDesign: This was a cross-sectional study.\n\nSetting: SB203580 mouse The study was conducted at a tertiary referral center. Patients and\n\nMethods: Coping styles were assessed using the Utrecht Coping List. The results from the study cohort were compared with a control group and data derived from the literature. Potential differences in coping styles
between the various SDH mutation carriers and PGL patients without an SDH mutation were explored.\n\nResults: Of the 174 patients who responded, 122 were SDHD, 25 SDHB, and 2 SDHC mutation carriers. An additional 25 patients lacked an SDH mutation. They recruited 100 peers as controls. Compared with the general population, the study cohort was more avoidant of problems (P < .001) and reported less expression of emotion (P < .01). Compared with patients with other conditions, they sought more social support (P < .001). There were no significant differences in coping styles between the various categories of mutation carriers or PGL patients lacking a mutation.\n\nConclusions: Coping styles of PGL patients and SDH mutation carriers differ from those of control and reference groups and include an avoidant coping style and a lack of emotional expression.
