Reduction of blood viscosity following plasma exchange
Atherosclerosis, 1979The effect of plasma exchange with plasma protein fraction on blood viscosity was determined in seven hyperlipoproteinaemic patients with coronary or peripheral vascular disease. This resulted in decreases in whole blood viscosity of 83% and 30% respectively at the lowest and highest shear rates studied, and decreases of 21% and 59% in plasma viscosity

Viscosity Reduction of Heavy Oil
2018The exploitation and transportation of heavy oil has been a challenging task due to its high viscosity and poor fluidity. To address these issues, it is necessary to study the properties and viscosity reduction methods of heavy oil. In this chapter, the composition and source of viscosity of heavy oil are introduced.

Viscosity reduction of pretreated softwood by endoglucanases
Journal of Chemical Technology & Biotechnology, 2018AbstractBACKGROUNDCost‐effective processing of lignocellulosic biomass into sugar derived products, such as biofuels or biochemicals, needs to be performed at high water insoluble solid (WIS) loading. However, the difficult rheology of such materials presents significant challenges.

Reduction in Viscosity of Cystic Fibrosis Sputum in Vitro by Gelsolin
Science, 1994Obstruction of airways by viscous sputum causes lung damage in patients with cystic fibrosis (CF). Sputum samples from CF patients were shown to contain filamentous actin. Human plasma gelsolin, a protein that severs actin filaments, rapidly decreased the viscosity of CF sputum samples in vitro.

Influence of acute reduction of blood viscosity on endothelial function
Clinical Hemorheology and Microcirculation, 2019BACKGROUND: The relationship between blood viscosity (BV) and endothelial function is rather complex. An increase in BV causes an increase in blood flow resistance, with negative hemodynamic effects; on the other hand, a moderate increase in BV causes an increase in wall stress shear (WSS), and consequent ...

Tailored Viscosity Reduction in Aqueous Hydroxypropylcellulose Solutions
MRS Proceedings, 1995AbstractPolysaccharides, including cellulosic derivatives such as hydroxypropylcellulose (HPC), are used extensively in the pharmaceutical industry due to their biocompatibility and self-organization properties. While drug delivery vehicles employing, for instance, aqueous polysaccharide gels are desirable, production of such gels can be hindered by ...

Heavy Oil Production Enhancement by Viscosity Reduction
Proceedings of SPE Western Regional Meeting, 2010Abstract This paper presents an evaluation of different chemical agents that can reduce dramatically the apparent viscosity of a heavy crude oil or a thick emulsion. The focus of this study is on methods to improve the production of heavy oils and very viscous emulsions such as are found in California, Canada, and Venezuela.

Downhole Emulsification: Viscosity Reduction Increases Production
Journal of Canadian Petroleum Technology, 1996Abstract The purpose of this paper is to present a further update on the use of surfactants to assist in the pumping of viscous crude oils in Western Canada. Typically, crude oils present downhole pumping problems due to the high natural viscosity of the oil, such as Alberta's heavy oils, or in ...
