Negative Control of Biodegradation in Pseudomonas.
1988Abstract : The objective of the research program was to characterize control mechanisms that exercised negative regulation on the expression of genes for aromatic catabolism in bacteria. The three sets of genes selected for investigation were ben, encoding enzymes that convert benzoate to catechol; cat, encoding enzymes tht convert catechol to citric ...

Synthetic, Implantable, Biodegradable Polymers for Controlled Release of Radiosensitizers
Cancer Biotherapy and Radiopharmaceuticals, 1999Synthetic, implantable, biodegradable polymers offer the sustained local release of disparate therapeutic agents for the treatment of human malignant brain tumors. The role of polymeric devices for the local delivery of radiosensitizers remains unexplored, however.

Control of biodegradation of biocompatable magnesium alloys
Corrosion Science, 2007By utilising its rapid corrosion reaction and controlling its degradation process through Zn and Mn alloying, purification and anodization, chemically active magnesium can be developed into a biodegradable biocompatible implant material with a specific biodegradation process and tolerable hydrogen evolution rate, which may replace current problematic ...

Electrospun biodegradable nanofiber nonwovens for controlled release of proteins
Journal of Controlled Release, 2008Electrospinning of emulsions composed of an organic poly(l-lactide) solution and an aqueous protein solution yielded protein containing nanofiber nonwovens (NNs) having a mean fiber diameter of approximately 350 nm. Cytochrome C was chosen as a hydrophilic model protein for encapsulation.

Biodegradable Polymers for the Controlled Delivery of Vaccines
1994New methods for the efficient and effective administration of vaccines are required particularly with the advent of new synthetic subunit vaccines. This chapter describes the approaches of several research groups to administer vaccines using biodegradable polymer carriers.

Control of Healing with Photopolymerizable Biodegradable Hydrogels
1996Post-surgical wound healing has been modified by the use of biodegradable hydrogel barriers to block cell adhesion to tissue surfaces, e.g. to the mesothelium in abdominopelvic surgery or to the subendothelium in angioplasty. These materials were formed in situ by photopolymerization of an aqueous precursor to obtain barriers that were conformai and ...

[Plasmids controlling biodegradation of epsilon-caprolactam].
Mikrobiologiia, 1991Bacterial strains (190) capable of growth on epsilon-caprolactam as a sole source of carbon and nitrogen were isolated from epsilon-caprolactam industrial sewage. Most of the strains (90%) were found to contain plasmids. Some of the strains (36.8%) assigned provisionally to the genus Pseudomonas contained plasmids controlling epsilon-caprolactam ...
