NYMC Student Theses and Dissertations

Food allergy is a highly prevalent disease affecting about 30 million people in the U.S. It is managed primarily by food avoidance due to lack of promising treatment options. ASHMI (anti-asthma herbal intervention) which consists of three components, Sophorae flavescentis, Ganoderma lucidum, Glycyrrhiza uralensis has been shown to inhibit allergic lung inflammation in antigen sensitized and challenged mice. In this study we isolate and identify the active compound in Sophorae flavescentis, characterized the mechanism of IgE inhibitory effect, biomarkers and potential to prevent food anaphylaxis.

To separate and identify the compounds we used column chromatography, high-performance liquid chromatography, mass …

Pharmacological Blockade Of The 20-Hete Receptor Lowers Blood Pressure And Alters Vascular Function In Mice With Vascular Smooth Muscle- Specific Overexpression Of Cyp4a12-20-Hete Synthase, Kevin Agostinucci

NYMC Student Theses and Dissertations

20-hydroxyeicosatetraenoic acid (20-HETE) is the ω-hydroxylation product of arachidonic acid catalyzed by CYP4A and 4F enzymes. 20-HETE is a vasoactive eicosanoid of the microcirculation exhibiting effects on both vascular smooth muscle cells (VSMC) and endothelial cells (EC). In VSMCs, 20-HETE’s bioactions include the stimulation of contraction, migration, and growth. In ECs, elevated 20-HETE is associated with reduced nitric oxide (NO) bioavailability, increased angiotensin converting enzyme (ACE) expression, and the promotion of inflammation. Recently in our laboratory, we identified GPR75 as a novel target of 20-HETE that promotes changes in blood pressure and vascular function. The aim of this study is …

Quantifying Differences In Pill Swallow Patterns In Adults, Catherine A. Sullivan, Luis F. Riquelme

Annual SHSP Student Research and Scholarship Day

Difficulty swallowing pills has become an increasing complaint among patients visiting swallow evaluation centers across the globe. Deficits are reported in healthy individuals as well as in clinical populations. In the USA, 40% of 679 persons responding to a survey reported difficulty swallowing pills (Business Wire, 2009). In an effort to facilitate pill intake, several modifications have been reported: use of liquid formulations, crushing tablet, opening capsule, whole pill mixed with food or via feeding tube (Cornish, 2005). A survey of 40 nurses revealed the most common modification was to use apple sauce (Riquelme et al., 2009). Current literature on …

The Fallacy Of Enzymatic Hydrolysis For The Determination Of Bioactive Curcumin In Plasma Samples As An Indication Of Bioavailability: A Comparative Study, Sidney J. Stohs, C. Y. O. Chen, Harry G. Preuss, Sidhartha D. Ray, Luke R. Bucci, Jin Ji, Kevin J. Ruff

Touro Scholarly Works

Background

Numerous health benefits have been demonstrated for curcumin which is extracted from turmeric (Curcuma longa L). However, due to its poor absorption in the free form in the gastrointestinal tract and rapid biotransformation, various formulations have been developed to enhance its bioavailability. Previous studies indicate that the free form of curcumin is more bioactive than its conjugated counterparts in target tissues. Most curcumin pharmacokinetics studies in humans designed to assess its absorption and bioavailability have measured and reported total (free plus conjugated) curcumin, but not free, bioactive curcumin in the plasma because enzymatic hydrolysis was employed prior to …

Applying Contemporary Management Principles To Implementing And Evaluating Value-Added Pharmacist Services., Shane P. Desselle, Leticia R Moczygemba, Antoinette B Coe, Karl Hess, David P Zgarrick

Faculty Publications & Research of the TUC College of Pharmacy

Value-added pharmacy services encompass traditional and emerging services provided by pharmacists to individual and entire populations of persons increasingly under the auspices of a public health mandate. The success of value-added pharmacy services is enhanced when they are carried out and assessed using appropriate theory-based paradigms. Many of the more important management theories for pharmacy services consider the "servicescape" of these services recognizing the uniqueness of each patient and service encounter that vary based upon health needs and myriad other factors. In addition, implementation science principles help ensure the financial viability and sustainability of these services. This commentary reviews some …

Co-Located Retail Clinics And Pharmacies: An Opportunity To Provide More Primary Care., Katherine K. Knapp, Keith Yoshizuka, Debra Sasaki-Hill, Rory Caygill-Walsh

Faculty Publications & Research of the TUC College of Pharmacy

This paper proposes that co-located retail clinics (RCs) and community pharmacies can increase opportunities to provide more accessible, affordable, and patient-friendly primary care services in the United States. RCs are small businesses of about 150-250 square feet with a clientele of about 10-30 patients each day and most frequently staffed by nurse practitioners (NPs). Community pharmacies in the U.S. at ~67,000 far outnumber RCs at ~2800, thereby opening substantial opportunity for growth. Community pharmacies and pharmacists have been working to increase on-site clinical services, but progress has been slowed by the relative isolation from other practitioners. An ideal merged facility …

A Randomized, Controlled Trial On The Effects Of Almonds On Lipoprotein Response To A Higher Carbohydrate, Lower Fat Diet In Men And Women With Abdominal Adiposity., Paul T. Williams, Nathalie Bergeron, Sally Chiu, Ronald M. Krauss

Faculty Publications & Research of the TUC College of Pharmacy

BACKGROUND: Almonds have been shown to lower LDL cholesterol but there is limited information regarding their effects on the dyslipidemia characterized by increased levels of very low density lipoproteins (VLDL) and small, dense low-density lipoprotein (LDL) particles that is associated with abdominal adiposity and high carbohydrate intake. The objective of the present study was to test whether substitution of almonds for other foods attenuates carbohydrate-induced increases in small, dense LDL in individuals with increased abdominal adiposity.

METHODS: This was a randomized cross-over study of three 3wk diets, separated by 2wk washouts: a higher-carbohydrate (CHO) reference diet (CHO

RESULTS: Relative to …

Novel Flexible Heteroarotinoid, Sl-1-39, Inhibits Her2-Positive Breast Cancer Cell Proliferation By Promoting Lysosomal Degradation Of Her2., Hongye Zou, Mary B. Sevigny, Shengquan Liu, David T. Madden, Maggie C. Louie

Faculty Publications & Research of the TUC College of Pharmacy

SL-1-39 [1-(4-chloro-3-methylphenyl)-3-(4-nitrophenyl)thiourea] is a new flexible heteroarotinoid (Flex-Het) analog derived from the parental compound, SHetA2, previously shown to inhibit cell growth across multiple cancer types. The current study aims to determine growth inhibitory effects of SL-1-39 across the different subtypes of breast cancer cells and delineate its molecular mechanism. Our results demonstrate that while SL-1-39 blocks cell proliferation of all breast cancer subtypes tested, it has the highest efficacy against HER2+ breast cancer cells. Molecular analyses suggest that SL-1-39 prevents S phase progression of HER2+ breast cancer cells (SKBR3 and MDA-MB-453), which is consistent with reduced expression of key cell-cycle …

A Bird's-Eye View Of The Multiple Biochemical Mechanisms That Propel Pathology Of Alzheimer's Disease: Recent Advances And Mechanistic Perspectives On How To Halt The Disease Progression Targeting Multiple Pathways., Caleb Vegh, Kyle Stokes, Dennis Ma, Darcy Wear, Jerome Cohen, Sidhartha D. Ray, Siyaram Pandey

Touro College of Pharmacy (New York) Publications and Research

Neurons consume the highest amount of oxygen, depend on oxidative metabolism for energy, and survive for the lifetime of an individual. Therefore, neurons are vulnerable to death caused by oxidative-stress, accumulation of damaged and dysfunctional proteins and organelles. There is an exponential increase in the number of patients diagnosed with neurodegenerative diseases such as Alzheimer’s (AD) as the number of elderly increases exponentially. Development of AD pathology is a complex phenomenon characterized by neuronal death, accumulation of extracellular amyloid-β plaques and neurofibrillary tangles, and most importantly loss of memory and cognition. These pathologies are most likely caused by mechanisms including …

Microneedle-Assisted Delivery Of Anti-Migraine Drugs Across Porcine Skin: Almotriptan Malate And Naratriptan Hydrochloride, Iqra Ahmad, Kevin B. Ita, Matthew J. Morra, Inna E. Popova

Faculty Publications & Research of the TUC College of Pharmacy

Migraine is a common neurological disorder characterized by nausea, vomiting, photophobia, aching, fever, pain and chills. Triptans are selective serotonin agonists which can used to relieve migraine symptoms. Almotriptan malate and naratriptan hydrochloride are currently used for the management of migraine in the form of oral tablets. Oral tablets may be problematic for patients experiencing nausea and vomiting which are often associated with migraine. The microneedle-assisted transdermal drug delivery of these triptans may improve patient compliance. A vertical six-celled, static Franz diffusion cell system was used to conduct in vitro permeation experiments on porcine ear skin to determine the influence …

Significant Inhibition Of Protein Binding Of Phenytoin, Sheril Alexander, Jesse Flores, Henrietta Ofuluozor, Mariana Babayeva

Touro College of Pharmacy (New York) Publications and Research

Aim: This research was aimed to assess the potential for inhibition of protein binding of phenytoin by tizoxanide in human plasma. Phenytoin was used because studies have proven to be a highly plasma protein-bound drug with a narrow therapeutic index and non-linear pharmacokinetics. Tizoxanide is another highly protein-bound active metabolite of an anti-infective prodrug nitazoxanide. Both drugs are expected to be administered together due to their therapeutic indications.

Study Design: The study was divided into two phases. Phase 1 produced a reference line of phenytoin protein binding values. Phase 2 was conducted to reveal the effect of the interactant tizoxanide …

Clinical Relevance Of Μ-Opioid Receptor A118g Polymorphism In Demographically Variant Populations, Iryna Pokotylyuk, Srishti Kulshrestha, Zvi G. Loewy, Priyank Kumar

Touro College of Pharmacy (New York) Publications and Research

Use of opioids is essential in providing a broad and effective analgesic effect. Opioid dosing has to be monitored and controlled in order to manage pain and the corresponding side effects due to opioid treatment. A very common single nucleotide polymorphism (SNP) associated with the µ opioid receptor is A118G. A118G, located on exon 1 of the µ-opioid receptor gene (OPRM1), may alter how patients respond to opioid treatment. This polymorphism results in an exchange of adenine for guanine, which in turn leads to substitution of asparagine for the aspartic acid. In order to understand how individuals with the G …

Faculty Publications & Research of the TUC College of Pharmacy

Francisella tularensis, the causative agent of the fatal human disease known as tularemia is classified as a Category A Select Agent by the Centers for Disease Control. No licensed vaccine is currently available for prevention of tularemia in the United States. Previously, we published that a tri-antigen tobacco mosaic virus (TMV) vaccine confers 50% protection in immunized mice against respiratory tularemia caused by F. tularensis. In this study, we refined the TMV-vaccine formulation to improve the level of protection in immunized C57BL/6 mice against respiratory tularemia. We developed a tetra-antigen vaccine by conjugating OmpA, DnaK, Tul4, and SucB proteins of …

Faculty Publications & Research of the TUC College of Pharmacy

Introduction: Substance use disorders (SUDs) are a significant US health problem affecting roughly 20 million Americans, but there continues to be limited access to SUD treatment and inadequate addiction medicine training. Therefore, it is important to understand how SUD education is being delivered to US health professionals, including pharmacists.

Methods: A recent survey of US pharmacy programs' neuropsychiatry curricula was evaluated to identify any progress made toward increasing SUD education since the last national survey in 2004 and determine any remaining gaps between what is currently being taught and American Association of Colleges of Pharmacy (AACP) curricular guidelines for SUD …

Real-World Usage And Clinical Outcomes Of Alectinib Among Post-Crizotinib Progression Anaplastic Lymphoma Kinase Positive Non-Small-Cell Lung Cancer Patients In The Usa, Marco D. Dibonaventura, William Wong, Bijal M. Shah-Manek, Mathias Schulz

Faculty Publications & Research of the TUC College of Pharmacy

Background: Alectinib is an approved treatment for anaplastic lymphoma kinase (ALK)-positive patients with advanced non-small-cell lung cancer. Despite positive supporting clinical data, there is a lack of real-world information on the usage and patient outcomes of those treated with alectinib post-crizotinib progression.

Methods: Participating oncologists (N=95) in the USA were recruited from an online physician panel to participate in a retrospective patient chart review. Physicians randomly selected eligible patients (ie, patients who progressed on crizotinib as their first ALK inhibitor and were treated with alectinib as their second ALK inhibitor), collected demographics and clinical history from their medical charts, and …

Intranasal Administration Of A Two-Dose Adjuvanted Multi-Antigen Tmv-Subunit Conjugate Vaccine Fully Protects Mice Against Francisella Tularensis Lvs Challenge, Alison A. Mccormick, Aisha Shakeel, Chris Yi, Hardeep Kaur, Ahd M. Mansour, Chandra Shekhar Bakshi

Faculty Publications & Research of the TUC College of Pharmacy

Tularemia is a fatal human disease caused by Francisella tularensis, a Gram-negative encapsulated coccobacillus bacterium. Due to its low infectious dose, ease of aerosolized transmission, and lethal effects, the CDC lists F. tularensis as a Category A pathogen, the highest level for a potential biothreat agent. Previous vaccine studies have been conducted with live attenuated, inactivated, and subunit vaccines, which have achieved partial or full protection from F. tularensis live vaccine strain (LVS) challenge, but no vaccine has been approved for human use. We demonstrate the improved efficacy of a multi-antigen subunit vaccine by using Tobacco Mosaic virus (TMV) as …

Pharmacy Technician-Administered Vaccines: On Perceptions And Practice Reality, Alex J. Adams, Shane P. Desselle, Kimberly C. Mckeirnan

Faculty Publications & Research of the TUC College of Pharmacy

Doucette and Schommer recently surveyed U.S. community pharmacy technicians on their willingness to perform tasks including the administration of vaccines. They found that 47.1% of technicians reported they were “unwilling” to administer a vaccine, although this finding must be placed into proper context. The first nationwide survey of U.S. pharmacist perceptions on immunizations in 1998 revealed only 2.2% of pharmacist respondents had administered adult vaccines and only 0.9% had administered childhood vaccines. They also found pharmacists to be “slightly negative on administering immunizations” with many perceived barriers. Nonetheless, pharmacist-provided immunizations have been an unqualified public health success. The theory of …

Ethics: A Problem In Pharmacy?, Keith I. Yoshizuka

Faculty Publications & Research of the TUC College of Pharmacy

Ethics, or the lack or attenuation thereof, is an important issue facing practicing pharmacists today. There are both statutory and regulatory provisions to support the requirement of ongoing education and training in ethics. Evidence of formal disciplinary actions by the California State Board of Pharmacy faced requiring pharmacists to take a formal course in ethics as a condition of retention of licensure is sufficient to demonstrate that pharmacists are deviating from the expectations consistent with ethical behavior. Periodic review of the principles of beneficence, non-malfeasance, autonomy, and justice would benefit pharmacists in practice, as evidence infers that a pharmacist’s moral …

Silver Nanoparticles And Drug Resistant Bacteria, Aliza Eisig

The Science Journal of the Lander College of Arts and Sciences

The scientist who discovered penicillin and its use as an antibiotic, Alexander Fleming, also raised concerns about bacterial resistance. As he predicted, in the twenty first century, the overwhelming use of antibiotics has led to both drug- and multi-drug resistant bacteria. This paper attempts to investigate the antibacterial potential of silver nanoparticles against drug resistant bacteria. By using Touro's online library database, the efficacy of silver nanoparticles as a potential antibacterial agent was comprehensively researched. Using transmission electron microscopy and the disk diffusion method, silver nanoparticles have been found to exert bactericidal effects by adsorbing to the cell surface and …

Cyclodextrin As A Drug Carrier Increasing Drug Solubility, Malka Silberberg

The Science Journal of the Lander College of Arts and Sciences

The development of a new drug requires research and evaluation before the drug is approved to enter the market. One of the factors determining the efficacy of a drug is the aqueous solubility of the drug. A current problem in today’s pharmaceutical industry is the low aqueous solubility of many useful drugs. A drug with a low aqueous solubility will not readily be absorbed by the body. The low aqueous solubility of a drug is often due to the drug’s hydrophobic character. Drug enhancement methods are necessary to avoid the obstacle of drug insolubility and many methods have been developed. …

A Case Of Amlodipine Overdose: Role Of High Dose Insulin Therapy, Kelvin Tran, Thinh Tang, Tarris Webber, Paul J. Kalekas, Quang T. Nguyen

College of Osteopathic Medicine (TUN) Publications and Research

Introduction: High dose insulin (HDI) therapy, defined as > 0.5 units/kg/hour, has been postulated to improve hemodynamics in both calcium channel blocker (CCB) and beta-blocker overdose. Proposed benefits of HDI include coronary and systemic vasodilation due to enhancement of nitric oxide synthase activity leading to improved contractility and decreased systemic vascular resistance, respectively. HDI also directly improves cardiac contractility by increasing glucose uptake and improving calcium handling within cardiac cells. We present a case of a patient with amlodipine overdose and her response to HDI therapy.

Case presentation: A 52 year old female presented with amlodipine overdose after suicide attempt leading …

Single Low-Dose Lipopolysaccharide Preconditioning: Neuroprotective Against Axonal Injury And Modulates Glial Cells, Ryan C. Turner, Zachary J. Naser, Brandon P. Lucke-Wold, Aric F. Logsdon, Reyna L. Vangilder, Rae Reiko Matsumoto, Jason D. Huber

Faculty Publications & Research of the TUC College of Pharmacy

AIM: Over 7 million traumatic brain injuries (TBI) are reported each year in the United States. However, treatments and neuroprotection following TBI are limited because secondary injury cascades are poorly understood. Lipopolysaccharide (LPS) administration before controlled cortical impact can contribute to neuroprotection. However, the underlying mechanisms and whether LPS preconditioning confers neuroprotection against closed-head injuries remains unclear.

METHODS: The authors hypothesized that preconditioning with a low dose of LPS (0.2 mg/kg) would regulate glial reactivity and protect against diffuse axonal injury induced by weight drop. LPS was administered 7 days prior to TBI. LPS administration reduced locomotion, which recovered completely …
