Hydrogen peroxide production using chemically treated Pichia pastoris cells
(Elsevier, 1994-01)
A new method has been developed to prepare intact cell systems to produce hydrogen peroxide (H2O2) using methylotrophic yeast Pichia pastoris. The high alcohol oxidase (EC 1.1.3.13; AOXase) content in the living P. pastoris ...
Reduction of porous media permeability from in situ Leuconostoc mesenteroides growth and dextran production
(Wiley Subscription Services, Inc., A Wiley Company, 1996-04-05)
In situ growth of bacteria in a porous medium can alter the permeability of that media. This article reveals that the rate of permeability alteration can be controlled by the inoculation strategy, nutrient concentrations, ...
Cell cycle dependence of retroviral transduction: An issue of overlapping time scales
(Wiley Subscription Services, Inc., A Wiley Company, 1998-04-20)
Recombinant retroviruses are currently used as gene delivery vehicles for the purpose of gene therapy. It is generally believed that the efficiency of retroviral transduction depends on the cell cycle status of the target ...
Effects of extractive fermentation on butyric acid production by Clostridium acetobutylicum
(Springer-Verlag, 1990-01)
The addition of an oleyl alcohol extractant to a batch fermentation of glucose by Clostridium acetobutylicum resulted in a concentration profile that was distinctly different from the non-extractive control fermentation. ...
Pharmacophore elements of the TIPP class of delta opioid receptor antagonists
(Kluwer Academic Publishers; ESCOM Science Publishers B.V. ; Springer Science+Business Media, 1994-10)
A series of tri-and tetrapeptides sharing the amino-terminal dipeptide unit Tyr-Tic, found in the high-affinity delta opioid receptor antagonist Tyr-Tic-Phe-Phe (TIPP), was prepared and evaluated in receptor binding assays ...
VCAM-1 influences Lymphocyte Proliferation and Cytokine Production during Mixed Lymphocyte Responses
(Elsevier, 1994-03)
The allogeneic mixed lymphocyte reaction (MLR) is regarded as an effective model for examining the events which occur during an allospecific immune response. Numerous studies have delineated the role of adherence molecule ...
Immunocytochemistry of sequence-related neuropeptides in Drosophila
(Elsevier, 1993-06)
Based on structure, activity, and expression, the Drosophila drosulfakinin I peptide (DSK I; FDDY(OSO3H)GHMRFamide) is similar to the vertebrate peptide, cholecystokinin.1 Dromyosuppressin (DMS; TDVDHVFLRFamide) is an ...
A five-year multicenter study of the susceptibility of the Bacteroides fragilis group isolates to cephalosporins, cephamins, penicillins, clindamycin, and metronidazole in the United States
(Elsevier, 1994-04)
Over 2800 clinical strains of the Bacteroides fragilis group were collected during a 5-year period from ten geographically separate sites and tested for their susceptibility to various antimicrobial agents using a broth ...
Effects of Mild Hypothermia on the Release of Regional Glutamate and Glycine During Extended Transient Focal Cerebral Ischemia in Rats
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1998-07)
The present study is to determine the effect of mild hypothermia (MHT) on the release of glutamate and glycine in rats subjected to middle cerebral artery occlusion and reperfusion. The relationship between amino acid ...
Nucleotide sequence and expression of the mouse corticotropin-releasing hormone gene
(Elsevier, 1991-06)
The mouse corticotropin-releasing hormone (CRH) gene has been isolated and characterized by DNA sequence analysis. The gene exhibits a structural organization similar to that of the human, rat, and ovine genes with two ...
