Nanoemulsion Formulation Of Pregabalin For Enhanced Nose To Brain Delivery And Biological Tracking Using Radiolabeling With 99mtc, Hend Fayez, Adli A. Selim, Rehab N. Shamma, Hassan M. Rashed

Bulletin of Faculty of Pharmacy Cairo University

Pregabalin is a γ-aminobutyric acid analogue used for the treatment of neuropathic pain, seizures, and anxiety disorders. After oral administration, its level of brain penetration is rather modest. In this research, pregabalin was formulated successfully as a nanoemulsion. To track the biodistribution of pregabalin nanoemulsion in vivo, radiolabelling of pregabalin using 99mTc was performed. The different factors affecting radiolabeling yield were studied and radiolabelling yield of 92.6 % was achieved. A biological evaluation was performed in Swiss Albino mice through comparing biodistribution of intranasal (IN) 99mTc-pregabalin nanoemulsion with intravenous (IV) 99mTc-pregabalin solution at different time intervals. Biodistribution results show a …

Tbi And Tau Loss-Of-Function Both Affect Naïve Ethanol Sensitivity In Drosophila, Gregg Roman

Faculty and Student Publications

Traumatic brain injury (TBI) is associated with alcohol abuse and higher ethanol sensitivity later in life. Currently, it is poorly understood how ethanol sensitivity changes with time after TBI and whether there are sex-dependent differences in the relationship between TBI and ethanol sensitivity. This study uses the fruit fly Drosophila melanogaster to investigate how TBI affects alcohol sensitivity and whether the effects are sex-specific. Our results indicate that flies have a significantly higher sensitivity to the intoxicating levels of ethanol during the acute phase post-TBI, regardless of sex. The increased ethanol sensitivity decreases as time progresses; however, females take longer …

Cannabidiol Exposure During Rat Pregnancy Leads To Labyrinth-Specific Vascular Defects In The Placenta And Reduced Fetal Growth, Daniel B. Hardy, David R C Natale, Kendrick Lee

Physiology and Pharmacology Publications

Introduction: Cannabis use is increasing among pregnant people, and cannabidiol (CBD), a constituent of cannabis, is often perceived as ‘‘natural’’ and ‘‘safe’’ as it is non-intoxicating. In utero, cannabis exposure is associated with negative health outcomes, including fetal growth restriction (FGR). The placenta supplies oxygen and nutrients to the fetus, and alterations in placental development can lead to FGR. While there has been some investigation into the effects of D9-THC, there has been limited investigation into the impacts of in utero gestational CBD exposure on the placenta. Methods: This study used histological and transcriptomic analysis of embryonic day (E)19.5 rat …

2018 2nd Place: Identifying The Effectiveness Of Plant Extracts For Treating Biofilms Of Escherichia Coli And Myxococcus Xanthus, Micah Burton

Harrisburg University Research Symposium: Highlighting Research, Innovation, & Creativity

Antibiotic resistance is a topic that is of growing concern in the field of medicine. Antibiotics act as growth blockers or act as toxins, killing the organism they affect. These biological weapons generate selective pressure leading to the current antibiotic crisis. This selective pressure causes resistant organisms to begin to emerge and over generations antibiotic resistance can develop and be spread among a bacterial population.

One of the key factors contributing to antibiotic resistance in bacteria is the ability for some bacteria to form and shield themselves within biofilms. Biofilms are masses of bacteria protected by a polysaccharide/ extracellular DNA …

Posters-at-the-Capitol

Melanoma is the fifth most common cancer in the US, with limited effective immunotherapeutic options available for patients. Avaren-Fc (AvFc) is a novel experimental immunotherapeutic agent with a unique “lectibody” property. It is capable of targeting cancer cells through the selective recognition of high mannose glycans, which are aberrantly overrepresented on the surface of malignant cells. AvFc can interact with circulating effector immune cells equipped with Fc receptors, such as natural killer (NK) cells to induce antibody-dependent cell-mediated cytotoxicity (ADCC) and kill cancer cells. Previous work has shown that AvFc effectively induces ADCC activity against B16F10 cancer cells in vitro …
