Alkylation of human albumin by the antimalarial artemisinin
(Elsevier, 1993-07-20)
The interaction between artemisinin and human serum was studied in vitro using [3H]-dihydroartemisinin and [14C]artemisinin. Approximately 20% of added drug was covalently bound to albumin in 24 hr. The results of electrospray ...
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, ...
DNA Sequences in the Promoter Region of the NF1 Gene Are Highly Conserved between Human and Mouse
(Elsevier, 1994-06)
The gene for type 1 neurofibromatosis (NF1) is most highly expressed in brain and spinal cord, although low levels of mRNA can be found in nearly all tissues. As a first step in investigating the regulation of NF1 gene ...
The ecology and evolution of tetracycline resistance
(Elsevier, 1992-09)
The use of tetracycline over the past few decades has been accompanied by a drastic increase in the frequency of tetracycline resistance in a wide range of bacterial species and genera. A diversity of resistance determinants ...
Acid- and base-treated Fe 3+ -TiO 2 -pillared clays for selective catalytic reduction of NO by NH 3
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-03)
Fe 3+ -ion-exchanged delaminated pillared clays (PILCs) have been found previously to be more active than the vanadia-based catalysts for selective catalytic reduction (SCR) of NO by NH 3 . The effects of acid treatment ...
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 ...
Affected-sib-pair interval mapping and exclusion for complex genetic traits: Sampling considerations
(Wiley Subscription Services, Inc., A Wiley Company, 1996)
We describe an extension of Risch's [(1990a,b) Am J Hum Genet 46:222–228, 229–241] method of linkage detection and exclusion for complex genetic traits. The method uses interval mapping to infer disease locus identity-by-descent ...
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 ...
