Biodegradable Hybrid Nanogels For Combination Chemotherapy, Swapnil Desale

Theses & Dissertations

Combination chemotherapy is commonly used to treat cancer, because such a therapy regimens usually involve sequential administration of multiple drugs and allow targeting different cell signaling pathway. The co-delivery of drug combination at a controlled ratio via the same vehicle is offering the advantages such as spatial-temporal synchronization of drug exposure, synergistic therapeutic effects and suppression of drug resistance. Undoubtedly, there are several molecular and pharmacological factors that determine the effectiveness of drug combinations. A rationally designed drug combination is required since certain drug ratios and the definitive exposure to the targets of interest can only be synergistic while others …

Antiviral Peptide Nanocomplexes As Potential Therapeutics For The Treatment Of Infectious Diseases, Jinjin Zhang

Theses & Dissertations

Hepatitis C Virus (HCV) is recognized as a major burden in global public health, which can be further exacerbated by several cofactors such as human immunodeficiency virus (HIV). Currently, there is no vaccine for HCV. The emergence of potent and highly specific direct-acting antivirals (DAA) has marked a new era in HCV therapy, however, the remaining issues like affordability, genotype dependency, and potential resistance still necessitate the development of additional therapeutic approaches to be used instead or in combination with DAA.

Recently, the antiviral peptide C5A (in our studies designated as p1) and its cationic derivative p41 have been identified …

Phenylephrine Versus Ephedrine: Safest Vasopressor For The Neonate During Caesarean Section, James S. Hale Jr.

Doctoral Projects

One of the most common side effects of spinal anesthesia is the development of hypotension. Data collected has determined that 80% of parturients that undergo spinal anesthesia for this mode of delivery experience hypotension (Chestnut et al., 2014).

Hypotension, if sustained and severe, can lead to fetal hypoxia, neonatal depression or injury, and decreased uteroplacental perfusion. Hypotension can also cause severe health issues for the parturient including apnea, altered level of consciousness, cardiac arrest, and pulmonary aspiration. This systematic review of the literature was conducted to determine whether the administration of phenylephrine or ephedrine was safer for the neonate to …

Predicting Human Drug Toxicity And Safety Via Animal Tests: Can Any One Species Predict Drug Toxicity In Any Other, And Do Monkeys Help?, Jarrod Bailey, Michelle Thew, Michael Balls

Laboratory Experiments Collection

Animals are still widely used in drug development and safety tests, despite evidence for their lack of predictive value. In this regard, we recently showed, by producing Likelihood Ratios (LRs) for an extensive data set of over 3,000 drugs with both animal and human data, that the absence of toxicity in animals provides little or virtually no evidential weight that adverse drug reactions will also be absent in humans. While our analyses suggest that the presence of toxicity in one species may sometimes add evidential weight for risk of toxicity in another, the LRs are extremely inconsistent, varying substantially for …

Pharmacy Practice and Science Faculty Publications

Pseudomonas aeruginosa is a common pathogen implicated in nosocomial infections with increasing resistance to a limited arsenal of antibiotics. Monte Carlo simulation provides antimicrobial stewardship teams with an additional tool to guide empiric therapy. We modeled empiric therapies with antipseudomonal β-lactam antibiotic regimens to determine which were most likely to achieve probability of target attainment (PTA) of ≥90%. Microbiological data for P. aeruginosa was reviewed for 2012. Antibiotics modeled for intermittent and prolonged infusion were aztreonam, cefepime, meropenem, and piperacillin/tazobactam. Using minimum inhibitory concentrations (MICs) from institution-specific isolates, and pharmacokinetic and pharmacodynamic parameters from previously published studies, a 10,000-subject Monte …
