Reproduction numbers and thresholds in stochastic epidemic models I. Homogeneous populations
(Elsevier, 1991-12)
We compare threshold results for the deterministic and stochastic versions of the homogeneous SI model with recruitment, death due to the disease, a background death rate, and transmission rate [beta]cXY / N. If an infective ...
Microprinted feeder cells guide embryonic stem cell fate
(Wiley Subscription Services, Inc., A Wiley Company, 2011-10)
We introduce a non‐contact approach to microprint multiple types of feeder cells in a microarray format using immiscible aqueous solutions of two biopolymers. Droplets of cell suspension in the denser aqueous phase are ...
An idealized concept of the true cladistic character
(Elsevier, 1975-04)
Estimating evolutionary relationships is basic to the objectives of systematics. Comparative data, structured as taxonomic characters, are usually the essential considerations on which such estimates are founded. Some ...
Physiological changes during the adaptation of hybridoma cells to low serum and serum-free media
(Wiley Subscription Services, Inc., A Wiley Company, 1991-01-05)
Two murine hybridoma cell lines (167.4G5.3 and S3H5/Γ2bA2) were adapted to grow in low-serum and serum-free media by a weaning procedure. The changes in cell growth, metabolic, and antibody production rates with adaptation ...
Effects of dimethyl sulfoxide on the globally ischemic heart: Possible general relevance to hypothermic organ preservation
(Elsevier, 1982-02)
Isolated perfused rabbit hearts were made globally ischemic for 2 hr, then reperfused. For 5 min before and after ischemia hearts were perfused with hypothermic (20 or 27 [deg]C), hypoxic, substrate-free cardioplegic ...
Cell affinity separations using magnetically stabilized fluidized beds: Erythrocyte subpopulation fractionation utilizing a lectin-magnetite support
(Wiley Subscription Services, Inc., A Wiley Company, 2003-03-20)
A magnetically stabilized fluidized bed is used to separate erythrocyte subpopulations. Binding specificity was obtained by immobilizing the lectin Helix pomatia Agglutinin (HpA) or Griffonia simplicifolia I (GSI) onto ...
Evaluation of encapsulating and microporous nondegradable hydrogel scaffold designs on islet engraftment in rodent models of diabetes
(Wiley Periodicals, Inc., 2018-09)
Islet transplantation is a promising therapeutic option for type 1 diabetes mellitus, yet the current delivery into the hepatic portal vasculature is limited by poor engraftment. Biomaterials have been used as a means to ...
Population balance between producing and nonproducing hybridoma clones is very sensitive to serum level, state of inoculum, and medium composition
(Wiley Subscription Services, Inc., A Wiley Company, 1992-02-05)
Secreting and nonsecreting hybridoma populations derived from the murine hybridoma cell line 167.4G5.3 were each grown in batch culture in low serum and serum-free media. Under serum-free conditions, a secreting population ...
A microfluidic bioreactor with integrated transepithelial electrical resistance (TEER) measurement electrodes for evaluation of renal epithelial cells
(Wiley Subscription Services, Inc., A Wiley Company, 2010-11-01)
We have developed a bilayer microfluidic system with integrated transepithelial electrical resistance (TEER) measurement electrodes to evaluate kidney epithelial cells under physiologically relevant fluid flow conditions. ...
