Semifluorinated alkanes (SFAs) are amphiphilic liquids that can dissolve hydrophobic drugs to form clear solutions. This study evaluated the potential of two SFAs to act as vehicle for topical ocular drug delivery. After confirming ocular safety, an ex vivo corneal penetration model was developed to determine drug distribution and corneal bioavailability. Hydrophobic dye distribution in the different corneal layers was visualised under a confocal microscope. Corneal bioavailability of cyclosporine A (CsA) dissolved in perfluorobutylpentane (F4H5) or perfluorohexyloctane (F6H8) was compared to commercially available CsA ophthalmic emulsions, Restasis® and Ikervis®...

To date, all monotherapy clinical traumatic brain injury (TBI) trials have failed, and there are currently no FDA-approved pharmacotherapies for the acute treatment of severe traumatic brain injury (TBI). Due to the complex secondary injury cascade following injury, there is a need to develop multi-mechanistic combinational neuroprotective approaches for the treatment of acute TBI. As central mediators of the TBI secondary injury cascade, both mitochondria and lipid peroxidation-derived aldehydes make promising therapeutic targets...

AIM: Cyclosporine A (CsA) induces renal vasoconstriction and hypoxia and enhances the expression of endothelin-1 (ET-1) pro-hormone (pre-pro ET-1), plausibly leading to a feed-forward loop of renal vasoconstriction, hypoxia, and enhanced synthesis of the potent vasoconstrictor ET-1. Endothelin converting enzyme (ECE)-1 cleaves big endothelin to generate endothelin (ET)-1 and is up-regulated by hypoxia via hypoxia-inducible factor (HIF). We hypothesized that in addition to the direct induction of ET-1 synthesis, CsA might also intensify renal ECE-1expression, thus contributing to enhanced ET-1 synthesis following CsA...

This article presents average agricultural yield data per hectare for key cereal, legume and root crops from 2001 until 2017. Data was obtained from the annual Agricultural Sample Surveys of the Central Statistics Agency (CSA) of Ethiopia. We present data at national, regional (SNNPRS) and zonal (Wolaita) levels. The data shows that average yields for all crops, at all levels, show increasing trends during the time period. Data for the main cereal crops is consistent and aligns with literature relatively well, however we raise questions about the root crop data in an effort to encourage greater critical reflection of components of data from the CSA...

Campus sexual assault (CSA) has received unprecedented attention over recent years, resulting in an abundance of federal guidance and mandates. In response, efforts to address and prevent CSA at Institutions of Higher Education (IHE) across the country have grown quickly, including the development and implementation of programs and policies. Because the changes on campuses have occurred at such a rapid pace, a number of gaps exist within the field of CSA research. To ensure that changes on IHE are evidence-based, there is a need to review the existing research available and the inquiry still needed, based on key areas outlined in federal guidance, the expressed needs of campus community members, survivors, and students who commit sexual offenses on college campuses...

Stressful early life experiences cause immune dysregulation across the lifespan. Despite the fact that studies have identified childhood sexual abuse (CSA) survivors as a particularly vulnerable group, only a few attempts have been made to study their lived-experience of the physical health consequences of CSA. The aim of this study was to explore a female CSA survivor's lived-experience of the physical health consequences of CSA and how she experienced the reactions of healthcare providers. Seven interviews were conducted with this 40-year-old woman, Anne, using a phenomenological research approach...

Mechanical unloading stimulates rapid changes in skeletal muscle morphology, characterized by atrophy of muscle fiber cross-sectional area (CSA) and a partial fiber-type shift from slow to fast-twitch. Recent studies revealed that oxidative stress contributes to activation of FoxO3a, proteolytic signaling and unloading-induced muscle atrophy via translocation of the mu-splice variant of neuronal nitric oxide synthase (nNOSμ) and activation of FoxO3a. Yet, there is limited understanding of the role of reactive oxygen species (ROS) on the Akt-mTOR pathway signaling during unloading...
