Recently, medication dosage errors have received more political and media attention. Dosage errors are the most common medical errors, affecting about 1.5 million people annually.
Furthermore, U.S. poison-control centers reported more than 200,000 cases per year of medication errors. These cases result in medical costs of around $3.5 billion, and children under 6 years old constitute approximately 30% of these cases.
The PROTECT Initiative (Preventing Overdoses and Treatment Errors in Children Taskforce) was launched in 2008 as a collaborative effort between public health agencies and patient advocates to minimize dosage errors.
In alignment with the PROTECT Initiative effort, this project …

Polybromo1 (PBRM1) is a chromatin remodeler subunit highly mutated in cancer, particularly clear cell renal carcinoma. PBRM1 is a member of the SWI/SNF subcomplex, PBAF (PBRM1-Brg1/Brm-associated factors), and is characterized by six tandem bromodomains. Here we establish a role for PBRM1 in epithelial cell maintenance through the expression of genes involved in cell adhesion, metabolism, stress response, and apoptosis. In support of a general role for PBRM1 in stress response and apoptosis, we observe that loss of PBRM1 results in an increase in reactive oxygen species generation and a decrease in cellular viability under stress conditions. We find that loss …

Current medications inadequately treat the symptoms of chronic pain experienced by over 50 million people in the United States, and may come with substantial adverse effects signifying the need to find novel treatments. One novel therapeutic target is the Transient Receptor Potential A1 channel (TRPA1), an ion channel that mediates nociception through calcium influx of sensory neurons. Drug discovery still relies heavily on animal models, including zebrafish, a species in which TRPA1 activation produces hyperlocomotion. Here, we investigated if this hyperlocomotion follows zebrafish TRPA1 pharmacology and evaluated the strengths and limitations of using TRPA1-mediated hyperlocomotion as potential preclinical screening tool …

Shannon L. Castek is a fourth-generation Boilermaker and fourth-professional-year student in the Purdue University College of Pharmacy. Throughout her time in pharmacy school, Shannon has enjoyed supplementing her curricular work with service-learning activities, participating in health screenings and immunization events with the Purdue chapter of the American Pharmacists Association–Academy of Student Pharmacists. She plans to pursue a pharmacy residency following graduation to achieve her dream of becoming an ambulatory care pharmacist. In this article, Shannon highlights the service-learning endeavors of Dr. Norman Fenn in the College of Pharmacy.

Christian Egly is a fourth-year (P4) pharmacy student in the Purdue University College of Pharmacy. During his years at Purdue, he worked in labs performing bench research in clinical pharmacology and biochemistry. He plans to work in the pharmaceutical industry after graduation. During his fourth year, he completed rotations in business development at Kashiv Pharma, LLC, and was hired there for an internship in 2017. In the article, Christian describes his personal experiences at Kashiv Pharma, LLC, and how industry can positively affect patient communities.
Macrophage Uptake And Cytotoxicity Of Paclitaxel Nanocrystals, Deborah Lee, Emeri Zhang, Wei Gao, Tonglei Li
Macrophage Uptake And Cytotoxicity Of Paclitaxel Nanocrystals, Deborah Lee, Emeri Zhang, Wei Gao, Tonglei Li
The Summer Undergraduate Research Fellowship (SURF) Symposium
Effective drug delivery remains one of the most challenging tasks in combatting cancer cells. Anti-cancer drugs such as Paclitaxel (PTX) often struggle in having a high drug effect because they are often phagocytized by macrophages in Reticuloendothelial System (RES) before reaching the cancer cells. To combat this problem, PTX was inserted in a nanocrystal, coated with non-ionic surfactant F68; it is speculated that this formulation will minimize the particle aggregation and decrease the cellular uptake in the RES, which will increase the overall efficacy of the drug in the target areas. The aim of this project was to compare the …

Impulsive behavior is the hallmark of many psychopathologies. Uncovering the neurobiological mechanisms driving impulsivity is paramount in the development of through the delay discounting (DD) task in both human and animal models. The present study is an examination of the predictive validity of the two primary types of DD procedures in animals, the Adjusting Amounts (AA) and within session Increasing Delays (ID) tasks. Methods:Subjects were administered either1.25 mg/kg d-amphetamine (AMP), 1.5 g/kg ethanol (EtOH) or saline and tested in either the AA or ID method for 15 days to evaluate drug effects on impulsive behavior. Results: Stimulant administration resulted …

Obesity is a significant global health problem and has been associated with altered pharmacokinetics and pharmacodynamics of many drugs. However, little is known regarding the effect of obesity on the pharmacokinetics and pharmacodynamics of many broad-spectrum, beta-lactam antibiotics such as piperacillin/tazobactam, meropenem, and cefepime. The objective of this study is to evaluate the population pharmacokinetics and pharmacodynamics of piperacillin/tazobactam, meropenem, and cefepime in hospitalized obese patients in order to determine dosing regimens that provide similar exposures between obese and non-obese patients. ^ For piperacillin/tazobactam, a retrospective analysis was conducted using prospectively collected serum concentration-time data from two previous studies (Study …

Monoamine neurotransmitter transporters are membrane proteins responsible for the clearing of biogenic amines from a synapse. These transporters are targets for many important pharmaceuticals including antidepressants, as well as psychostimulant drugs such as cocaine and amphetamines. Amphetamines are believed to elicit their psychostimulant activity primarily by inducing a reversal of the transport cycle and increasing neurotransmitter release into the synapse, though the mechanism of this activity is incompletely understood. Previous in vitro research has suggested functional significance of a conserved salt bridge in the serotonin transporter (SERT) in amphetamine-induced 5-HT efflux. This salt bridge is disrupted in the Drosophila melanogaster …
Investigation Into The Control Of Melittin Secondary Structure And Antimicrobial Activity, Zachary B. Molinets
Investigation Into The Control Of Melittin Secondary Structure And Antimicrobial Activity, Zachary B. Molinets
Open Access Theses
Antimicrobial resistance has been an exponentially growing problem since the discovery of antibiotics. Antibiotics have been misused for many years and this misuse has grown into a real problem for the medical community. While there are countless safeguards to prevent infection by a resistant strain of bacteria, there are still many plagued by it and must be treated with sometimes dangerous antibiotics. Melittin, along with many other peptides, contain potent antimicrobial properties, but are also toxic toward enthrocytes. The control of the secondary structure of peptides provides the key to adjusting their activity.

Parkinson's disease (PD) is the second most common neurodegenerative disorder after Alzheimer's disease, affecting approximately 0.3% of the total U.S. population, and its prevalence increases with age. Two neuropathological hallmarks of PD are the loss of dopaminergic neurons in the substantia nigra pars compacta, a region in the midbrain involved in initiating and sustaining movement, and the presence of cytosolic inclusions called Lewy bodies (LBs) in various brain regions. LBs are enriched with fibrillar forms of the presynaptic protein &agr;-synuclein (aSyn). Two autosomal recessive genes implicated in familial PD are PARK9, encoding the P-type ATPase ATP13A2, a lysosomal ATPase; and …
