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 ...
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 ...
Interleukin-1 induced gene expression of neutrophil activating protein (interleukin-8) and monocyte chemotactic peptide in human synovial cells
(Elsevier, 1991-01-31)
We report here that human synovial cells stimulated by interleukin-1[alpha] and interleukin-1[beta] express mRNA for both IL-8 (neutrophil chemotactic peptide) and monocyte chemotactic protein. IL-1 stimulated synovial ...
A triple-resonance pulse scheme for selectively correlating amide 1 H N and 15 N nuclei with the 1 H α proton of the preceding residue
(Kluwer Academic Publishers; ESCOM Science Publishers B.V. ; Springer Science+Business Media, 1992-07)
A 3D 1 H− 15 N− 13 C triple resonance experiment is presented that contains exclusively cross peaks between the 1 H N and 15 N nuclei of one residue with the H α of the preceding residue. The pulse sequence, designed to ...
Photoperiodic requirements for timing onset and duration of the breeding season of the ewe: Synchronization of an endogenous rhythm of reproduction
(Springer-Verlag, 1990-04)
A study was conducted to test the hypothesis that different portions of the annual photoperiodic cycle play different roles in timing the breeding season of the ewe, Ovis aries , an animal in which an endogenous rhythm ...
Chromosomal localization of the large subunit of mouse replication factor C in the mouse and human
(Springer-Verlag, 1995-01)
A Myosin from a Higher Plant has Structural Similarities to Class V Myosins
(Elsevier, 1994-06-16)
In plant cells, myosin is believed to be the molecular motor responsible for actin-based motility processes such as cytoplasmic streaming and directed vesicle transport. In an effort to characterize plant myosin, a cDNA ...
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 ...
Identification and localization of an immunoreactiveAMPA-type glutamate receptor subunit (GluR4) with respect to identified photoreceptor synapses in the outer plexiform layer of goldfish retina
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1997-10)
L-glutamate, the main excitatory synaptic transmitter in the retina, is released from photoreceptors and evokes responses in second-order retinal neurons (horizontal, bipolar cells) which utilize both ionotropic and ...
Characterization of receptors for glucagon-like peptide-1(7-36) amide on rat lung membranes
(Elsevier, 1990-07-02)
Specific binding of 125I-labelled GLP-1(7-36)amide to rat lung membranes was dependent upon time and temperature and was proportional to membrane protein concentration. Binding was inhibited in a concentration-dependent ...
