Novel Therapy For Nicotine Addiction In Alcohol Dependent Rats, Bethany Ann Stennett Jan 2013

Novel Therapy For Nicotine Addiction In Alcohol Dependent Rats, Bethany Ann Stennett

UNF Graduate Theses and Dissertations

The co-dependence of nicotine and alcohol addiction occurs at high rates, complicates treatment, and is often associated with significant morbidity and mortality. Treatment options of alcohol and tobacco co-dependence are limited. Currently, there are drugs available for nicotine dependence or alcohol dependence. However, there are no therapeutic drugs available on the market for the co-dependence of nicotine and alcohol. Therefore, and important opportunity of new therapeutic options and drug development has presented itself. NT69L, a non-selective neurotensin (NT) agonist, provides a potential novel therapy for nicotine addiction in alcoholics by interacting with the common neurotransmitter circuits supporting the rewarding process …


Phase Composition Control Of Calcium Phosphate Nanoparticles For Tunable Drug Delivery Kinetics And Treatment Of Osteomyelitis. Part 1: Preparation And Drug Release, Vuk Uskoković, Tejal A. Dasai Jan 2013

Phase Composition Control Of Calcium Phosphate Nanoparticles For Tunable Drug Delivery Kinetics And Treatment Of Osteomyelitis. Part 1: Preparation And Drug Release, Vuk Uskoković, Tejal A. Dasai

Pharmacy Faculty Articles and Research

Developed in this study is a multifunctional material for simultaneous osseoinduction and drug delivery, potentially applicable in the treatment of osteomyelitis. It is composed of agglomerates of nanoparticles of calcium phosphate (CAP) with different monophasic contents. The drug loading capacity and the release kinetics were investigated on two model drug compounds with different chemical structures, sizes and adsorption propensities: bovine serum albumin and fluorescein. Loading of CAP powders with small molecule drugs was achieved by physisorption and desiccation-induced agglomeration of nanoparticulate subunits into microscopic blocks. The material dissolution rate and the drug release rate depended on the nature of the …


Multifunctional Hydroxyapatite And Poly(D,L-Lactide-Co-Glycolide) Nanoparticles For The Local Delivery Of Cholecalciferol, Nenad Ignjatović, Vuk Uskoković, Zorica Ajduković, Dragan Uskoković Jan 2013

Multifunctional Hydroxyapatite And Poly(D,L-Lactide-Co-Glycolide) Nanoparticles For The Local Delivery Of Cholecalciferol, Nenad Ignjatović, Vuk Uskoković, Zorica Ajduković, Dragan Uskoković

Pharmacy Faculty Articles and Research

Cholecalciferol, vitamin D3, plays an important role in bone metabolism by regulating extracellular levels of calcium. Presented here is a study on the effects of the local delivery of cholecalciferol (D3) using nanoparticulate carriers composed of hydroxyapatite (HAp) and poly(D,L-lactide-co-glycolide) (PLGA). Multifunctional nanoparticulate HAp-based powders were prepared for the purpose of: (a) either fast or sustained, local delivery of cholecalciferol, and (b) the secondary, osteoconductive and defect-filling effect of the carrier itself. Two types of HAp-based powders with particles of narrowly dispersed sizes in the nano range were prepared and tested in this study: HAp nanoparticles as direct cholecalciferol delivery …
