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 ...
Induction of NF-[chi]B during monocyte differentiation is associated with activation of HIV-gene expression
(Elsevier, 1991)
Cells of the monocyte-macrophage lineage are important targets of HIV infection. We report here that the phenotypic differentiation of monocyte cell lines induced by phorbol esters or tumour necrosis factor [alpha] ...
Lipid-Dependent Modulation of Ca 2+ Availability in Isolated Mossy Fiber Nerve Endings
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1997-10)
An enhancement of glutamate release from hippocampal neurons has been implicated in long-term potentiation, which is thought to be a cellular correlate of learning and memory. This phenomenom appears to be involved the ...
Effects of single and repeated electroconvulsive therapy sessions on plasma ACTH, prolactin, growth hormone and cortisol concentrations
(Elsevier, 1991)
To study the effects of electroconvulsive therapy (ECT) on hormone release, we measured circulating concentrations of adrenocorticotropic hormone (ACTH), prolactin (PRL), growth hormone (GH) and cortisol (CORT) immediately ...
Regulatory mechanisms underlying T cell integrin receptor function
(Elsevier, 1993-08)
Adhesion molecules allow lymphocytes to interact with and respond to the extracellular environment. Since these interactions must be essentially transient in nature, the function of lymphocyte adhesion molecules must be ...
Isolation and Immunocytochemical Characterization of Three Tachykinin-Related Peptides from the Mosquito, Culex salinarius
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1998-02)
Three myotropic peptides belonging to the Arg-amide insect tachykinin family were isolated from whole-body extracts of the mosquito, Culex salinarius . The peptides, APSGFMGMR-NH 2 , APYGFTGMR-NH 2 and APSGFFGMR-NH 2 ...
Stereoselective high-performance liquid chromatographic assay for pirmenol enantiomers in dog plasma
(Elsevier, 1991-12-15)
Pirmenol enantiomers in dog plasma were quantified using a stereospecific high-performance liquid chromatographic method with ultraviolet detection at 262 nm. Racemic pirmenol and internal standard, (+)-propranolol, were ...
Effect of mecillinam on peptidoglycan synthesis during the division cycle of Salmonella typhimurium 2616
(Elsevier, 1993)
The effects of mecillinam, ampicillin and cephalexin on peptidoglycan synthesis in Salmonella typhimurium 2616 have been studied at equivalent concentrations or "isoactivities". Using antibiotics at isoactivities allows a ...
Galanin inhibits rat pancreatic amylase release via cholinergic suppression
(Elsevier, 1992)
The effects of galanin on pancreatic exocrine function were examined using rat pancreatic tissues. In anesthetized rats, galanin (40 [mu]g/kg/h) decreased amylase secretion stimulated by 2-deoxy glucose (5.8 +/- 0.1 vs. ...
The participation of coenzyme Q in free radical production and antioxidation
(Elsevier, 1990)
Published experimental data pertaining to the participation of coenzyme Q as a site of free radical formation in the mitochondrial electron transfer chain and the conditions required for free radical production have been ...
