Multiple Protein Kinases Determine The Phosphorylated State Of The Small Heat Shock Protein, Hsp27, In Sh-Sy5y Neuroblastoma Cells, Linda A. Dokas, Amy M. Malone, Frederick E. Williams, Surya M. Nauli, William S. Messer Jr.

Pharmacy Faculty Articles and Research

In SH-SY5Y human neuroblastoma cells, the cholinergic agonist, carbachol, stimulates phosphorylation of the small heat shock protein 27 (HSP27). Carbachol increases phosphorylation of both Ser-82 and Ser-78 while the phorbol ester, phorbol-12, 13-dibutyrate (PDB) affects only Ser-82. Muscarinic receptor activation by carbachol was confirmed by sensitivity of Ser-82 phosphorylation to hyoscyamine with no effect of nicotine or bradykinin. This response to carbachol is partially reduced by inhibition of protein kinase C (PKC) with GF 109203X and p38 mitogen-activated protein kinase (MAPK) with SB 203580. In contrast, phosphorylation produced by PDB is completely reversed by GF 109203X or CID 755673, an …

A Prospective Study Of Positive Psychological Well-Being And Coronary Heart Disease, Julia K. Boehm, Christopher Peterson, Mika Kivimaki, Laura D. Kubzansky

Psychology Faculty Articles and Research

Objective: Research suggests that positive psychological well-being is associated with cardiovascular health. However, much of this research uses elderly samples and has not determined the pathways by which psychological well-being influences cardiovascular disease or whether effects are similar for men and women. This study investigates the association between two aspects of well-being (emotional vitality and optimism) and coronary heart disease (CHD) in a sample of middle-aged men and women, and considers potential mediating factors.

Method: Between 1991 and 1994, well-being and coronary risk factors were assessed among 7,942 individuals without a prior cardiovascular event from the Whitehall II …

Development Of A Positive Psychology Intervention For Patients With Acute Cardiovascular Disease, Jeff C. Huffman, Carol A. Mastromauro, Julia K. Boehm, Rita Seabrook, Gregory L. Fricchione, John W. Denninger, Sonja Lyubomirsky

Psychology Faculty Articles and Research

The management of depression and other negative psychological states in cardiac patients has been a focus of multiple treatment trials, though such trials have not led to substantial improvements in cardiac outcomes. In contrast, there has been minimal focus on interventions to increase positive psychological states in cardiac patients, despite the fact that optimism and other positive states have been associated with superior cardiovascular outcomes. Our objective was to develop an 8-week, phone-based positive psychology intervention for patients hospitalized with acute cardiac disease (acute coronary syndrome or decompensated heart failure). Such an intervention would consist of positive psychology exercises adapted …

Morphological Study Of Emulsion-Assisted Cholesterol Precipitation Processes, Vuk Uskoković

Pharmacy Faculty Articles and Research

Crystallization of cholesterol in chemical conditions that involve the presence of emulsions of three different types of surface active agents—cationic, anionic, and nonionic—was investigated by means of scanning and transmission electron microscopic analyses. In contrast with the previous attempts to modify the typical plate- and needle-shaped character of biaxially grown cholesterol crystals, the present study indicates that spherical templates of fine emulsion droplets may impose spherical morphologies to cholesterol particles nucleated within.

Practice Patterns For Antibiotic De-Escalation In Culture-Negative Healthcare-Associated Pneumonia, M. Schlueter, C. James, A. Dominguez, Laura V. Tsu, G. Seymann

Pharmacy Faculty Articles and Research

Background Published guidelines for the treatment of healthcare-associated pneumonia (HCAP) recommend initial broad-spectrum antibiotics with appropriate de-escalation based on culture results. Guideline recommendations are based on data from intubated patients, in whom cultures are easily obtained. The approach to antibiotic de-escalation for culture-negative patients has not been addressed. Consequently, there are no published reports that describe the current standard of practice. Patients and methods All patients admitted to a university hospital with a diagnosis of HCAP, as defined by use of a pneumonia orderset, were identified retrospectively over a 2-year period. Antibiotics prescribed on admission, during hospital stay, and on …

Surface Charge Effects Involved In The Control Of Stability Of Sols Comprising Uniform Cholesterol Particles, Vuk Uskoković

Pharmacy Faculty Articles and Research

The reported is a method for the preparation of stable dispersions of narrowly dispersed cholesterol crystals, which may provide an excellent model for the aggregation studies thereof. The effects of experimental parameters that include concentration, pH, ionic strength, temperature, and aging on the resulting morphologies are acknowledged. Regardless of the cause of destabilization, the multilayered aggregates of cholesterol particles are formed by “face-to-face” stacking of the original platelets, as promoted by higher surface charge density on particle sides comparing to their faces. In accordance with the crucial involvement of surface charge effects in stabilization of cholesterol dispersions produced hereby, aggregation …

Insights Into Morphological Nature Of Precipitation Of Cholesterol, Vuk Uskoković

Pharmacy Faculty Articles and Research

Additional effects on the previously reported procedure of precipitation of narrowly dispersed and well-defined, brick-shaped cholesterol particles, including non-solvent addition rate, temperature, solvent purity, aging treatments, ultrasound agitation and fine mechanical effects were investigated. Based on the presented results, significant morphological sensitivity of cholesterol precipitation processes upon variations from the standard established procedure of crystallization is induced. However, the tendency of cholesterol to crystallize in the form of biaxially grown particles was evidenced as dominating the precipitation processes, irrespective of any modifications of experimental parameters involved in the preparation procedure investigated hereby. Prolonged aging time and temperature effects lead to …

Pharmacy Faculty Articles and Research

Whereby cholesterol presents one of the major fatty substances in human body, carboxymethyl cellulose is a water-soluble derivative of cellulose, the most abundant dietary fiber. Whereas on one hand in vivo precipitation of cholesterol is the major cause of atherosclerosis, dietary fibers are on the other hand known for their ability to clean the fatty plaque deposited on intestinal pathways, and prevent its build-up in other critical areas within the organism. In this work, a method for the preparation of a composite material comprising cholesterol and carboxymethyl cellulose from 1-hexanol/water biphase mixtures is reported. Specificity of the interaction between the …

Uniform Particles Of Pure And Silica Coated Cholesterol, Vuk Uskoković, Egon Matijević

Pharmacy Faculty Articles and Research

Uniform crystalline colloidal cholesterol particles of narrow size distribution were obtained by precipitation. The method consisted of adding a miscible non-solvent (water) into cholesterol solutions of different alcohols and acetone, without any additives. The properties of the resulting particles depended in a sensitive way on the concentration of all reactants, temperature, pH, ionic strength, and aging time. The major observed effects were due to the solubility of cholesterol, which was strongly affected by the solvent mixture and temperature. Precipitation in 1-propanol/water system yielded stable dispersions of well-defined particles, which were used to evaluate the effects of different experimental parameters on …

Stereospecific Pharmacokinetics And Pharmacodynamics Of Beta-Adrenergic Blockers In Humans, Reza Mehvar, Dion R. Brocks

Pharmacy Faculty Articles and Research

The beta-blockers comprise a group of drugs that are mostly used to treat cardiovascular disorders such as hypertension, cardiac arrhythmia, or ischemic heart disease. Each of these drugs possesses at least one chiral center, and an inherent high degree of enantioselectivity in binding to the b-adrenergic receptor. For beta-blockers with a single chiral center, the (-) enantiomer possesses much greater affinity for binding to the b-adrenergic receptors than antipode. The enantiomers of some of these drugs possess other effects, such as antagonism at alpha-adrenergic receptors or Class III antiarrhythmic activity. However, these effects generally display a lower level of stereoselectivity …
