Cell growth and differentiation on feeder layers is predicted to be influenced by bioreactor geometry
(Wiley Subscription Services, Inc., A Wiley Company, 1996-06-05)
Tissue function is comprised of a complex interplay between biological and physicochemical rate processes. The design of bioreactors for tissue engineering must account for these processes simultaneously in order to obtain ...
Inhibitory effects of clonidine on serotonergic neuronal activity as measured by cerebrospinal fluid serotonin and its metabolite in anesthetized rats
(Elsevier, 1993)
Clonidine-induced changes in the serotonergic neuronal activity of the central nervous system were estimated by measuring the concentrations of serotonin (5-HT) and its major metabolite, 5-hydroxyindole-3-acetic acid ...
Proboscidean DNA from Museum and Fossil Specimens: An Assessment of Ancient DNA Extraction and Amplification Techniques
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1997-06)
Applications of reliable DNA extraction and amplification techniques to postmortem samples are critical to ancient DNA research. Commonly used methods for isolating DNA from ancient material were tested and compared using ...
A sequence that directs transcriptional initiation in yeast
(Springer-Verlag, 1990-08)
While RNA polymerase II of the yeast Saccharomyces cerevisiae initiates transcription at discrete sites, these sites are located over a wide range of distances from the TATA box for different genes. This variability has ...
Autoradiographic evidence that transport of newly synthesized neuropeptides is directed to release sites in the X-organsinus gland of Cardisoma carnifex
(Springer-Verlag, 1991-05)
Sections of isolated X-organ — sinus gland neurosecretory systems of the crab, Cardisoma carnifex , were studied by light-and electron microscopy with conventional and autoradiographic procedures. The somata only were ...
Size-biased dispersal prior to breeding in a damselfly
(Springer-Verlag, 1990-06)
Dispersal is notoriously difficult to measure, so its potential population consequences are often unknown. If dispersal is density-dependent, it can act in population regulation. Adult damselflies Enallagma boreale (Zygoptera: ...
Localization of the thyrotropin-releasing hormone gene, Trh , on mouse Chromosome 6
(Springer-Verlag, 1995-06)
Towards liver-directed gene therapy: Retrovirus-mediated gene transfer into human hepatocytes
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1991-11)
Liver-directed gene therapy is being considered in the treatment of inherited metabolic diseases. One approach we are considering is the transplantation of autologous hepatocytes that have been genetically modified with ...
Antagonistic pleiotropy, mutation accumulation, and human genetic disease
(Kluwer Academic Publishers; Springer Science+Business Media, 1993-02)
The antagonistic pleiotropy theory of senescence is the most convincing theoretical explanation of the existence of aging. As yet, no locus or allele has been identified in a wild population with the features predicted by ...
Copper-induced expression, cloning, and regulatory studies of the plastocyanin gene from the cyanobacterium Synechocystis sp. PCC 6803
(Kluwer Academic Publishers; Springer Science+Business Media, 1990-10)
Plastocyanin can be detected in Synechocystis sp. PCC 6803 when 3 μM copper is added to the growth medium, BG-11. The plastocyanin gene ( petE ) was cloned from a genomic λ EMBL 3 library by screening with the petE gene ...
