Pharmaceutical M&A Activity: Effects On Prices, Innovation, And Competition, Barak D. Richman, Will Mitchell, Elena Vidal, Kevin Schulman

Faculty Scholarship

The rise of blockbuster pharmaceutical acquisitions has prompted fears that unprecedented market concentration will weaken competition. Two of the most prominent concerns focus on the upstream and downstream ends of the pharmaceutical industry: (1) the concern that these mergers will concentrate the market for discovery and will therefore lead to fewer discoveries; and (2) the concern that merging large marketing, sales, and distribution forces will strengthen the hands of select pharmaceutical manufacturers and weaken downstream competition. Having considered potential dynamic effects in the industry and conducted a series of preliminary interviews with knowledgeable observers, though, this Article argues that neither …

Mechanism Of Interaction Of Peptide Modified Nanoparticles With Porphyromonas Gingivalis., Ankita Jain

Electronic Theses and Dissertations

Studies suggest that P. gingivalis functions as a keystone pathogen and interacts with primary colonizers in the supragingival biofilm such as S. gordonii. This interaction contributes to the initial colonization of the oral cavity by P. gingivalis and thus represents a potential target for therapeutic intervention. We have identified a peptide (BAR) derived from the streptococcal SspB protein that functions to inhibit P. gingivalis adherence to S. gordonii. In addition, we showed that nanoparticles (NPs) functionalized with BAR inhibit this interaction more potently than free soluble peptide, possibly by promoting interaction with P. gingivalis at higher valency than …

Carriers For The Tunable Release Of Therapeutics: Etymological Classification And Examples, Vuk Uskoković, Shreya Ghosh

Pharmacy Faculty Articles and Research

Introduction—Physiological processes at the molecular level take place at precise spatiotemporal scales, which vary from tissue to tissue and from one patient to another, implying the need for the carriers that enable tunable release of therapeutics.

Areas Covered—Classification of all drug release to intrinsic and extrinsic is proposed, followed by the etymological clarification of the term “tunable” and its distinction from the term “tailorable”. Tunability is defined as analogous to tuning a guitar string or a radio receiver to the right frequency using a single knob. It implies changing a structural parameter along a continuous quantitative scale and …

Reactive Oxygen Species Modulation Of Na/K-Atpase Regulates Fibrosis And Renal Proximal Tubular Sodium Handling, Jiang Liu, David J. Kennedy, Yanling Yan, Joseph I. Shapiro Md

Yanling Yan

The Na/K-ATPase is the primary force regulating renal sodium handling and plays a key role in both ion homeostasis and blood pressure regulation. Recently, cardiotonic steroids (CTS)-mediated Na/K-ATPase signaling has been shown to regulate fibrosis, renal proximal tubule (RPT) sodium reabsorption, and experimental Dahl salt-sensitive hypertension in response to a high-salt diet. Reactive oxygen species (ROS) are an important modulator of nephron ion transport. As there is limited knowledge regarding the role of ROS-mediated fibrosis and RPT sodium reabsorption through the Na/K-ATPase, the focus of this review is to examine the possible role of ROS in the regulation of Na/K-ATPase …

Lack Of Cross-Reactivity Allergy Following A Switch From Alirocumab To Evolocumab, Matthew D. Stryker, Michael Kane, Robert Busch

Excerpts in Pharmacy Research Journal

The proprotein convertase subtilisin/kexin type 9 (PCSK9) gene and gain-of-function mutations were first described in 2003. The gain-of-function mutations observed were associated with low-density lipoprotein-cholesterol (LDL-C) levels in the 400’s, in addition to premature cardiovascular disease. Subsequent loss-of-function experiments conducted in mice demonstrated marked reductions in plasma cholesterol levels in the absence of PCSK9. Physiologically, PCSK9 serves as a chaperone protein and functions to reduce low-density lipoprotein (LDL) receptor recycling; consequently, less LDL-C is removed from circulation and serum lipid concentrations become elevated. Inhibition of PCSK9 prevents LDL receptor degradation and preserves receptor recycling to the hepatocyte surface; this in …
