Hybridoma cells (S3H5/gamma2bA2) were cultivated in spinner flasks with 1% serum media and serum-free media. Monoclonal antibody productivity was maintained in 1% serum media. However, cells in serum-free media showed a decrease in antibody productivity, and it completely disappeared in IMDM-based low protein medium. This loss of antibody productivity was not observed when the cells were immobi...

OBJECTIVES The aim of the study was to investigate the association between activity of ankylosing spondylitis (AS) and decrease in quality of life as well as productivity loss of affected patients in a specified group of patients in the Polish setting. MATERIAL AND METHODS An questionnaire survey was conducted using the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) to assess dis...

OBJECTIVE To measure and value the impact of combined etanercept (ETN) and methotrexate (MTX) therapy on work productivity in patients with early rheumatoid arthritis (RA) over 52 weeks. METHODS MTX- and biological-naïve patients with RA (symptom onset ≤12 months; Disease Activity Score based on a 28-joint count (DAS28) >3.2) received open-label ETN50/MTX for 52 weeks. The Valuation of Lost P...

Empirical studies document that resource reallocation across production units plays an important role in accounting for aggregate productivity growth in the U.S. manufacturing. Distortions in financial market could hinder the reallocation process and hence may adversely affect aggregate productivity growth. This paper studies the quantitative impact of costly external finance on aggregate produ...

BACKGROUND National working groups identify the need for return on investment research conducted from the purchaser perspective; however, the field has not developed standardized methods for measuring the basic components of return on investment, including costing out the value of work productivity loss due to illness. Recent literature is divided on whether the most commonly used method undere...

OBJECTIVES There were two study objectives: (i) to identify, via consensus, a key set of items for estimating the costs of productivity loss from a company's perspective and (ii) to develop recommendations for the costs of estimating productivity loss on the basis of consensus findings. METHODS A modified Delphi procedure was utilized in which a predetermined set of 26 items formed the basis ...
