Abstract:
The invention relates to a class of polycyclic compounds that reacts with and neutralizes a reactive oxygen species, such as a free oxygen radical, in a patient and which can then be regenerated back to their original reactive chemical form by a naturally occurring enzyme in said patient. These compounds are useful to treat diseases in a patient characterized by a reactive oxygen species. Moreover, because these compounds can be regenerated back to their original, reactive chemical state in vivo, a single molecule can neutralize multiple molecules of the reactive species. This allows for the use of lower dosages for the treatment of disease, as compared to compounds presently used to treat that same disease, thus avoiding side effects associated with higher dosages.
Abstract:
A detection device comprised of a hybrid nucleic acid assembly. The device further comprises a nucleic acid polymer, a first nanoparticle conjugated to the nucleic acid polymer, a second nanoparticle conjugated with the nucleic acid polymer, a means for introducing energy into the first nanoparticle, means for detecting energy from the second nanoparticle, and means for determining a physical property of the nucleic acid polymer, wherein the means of introducing energy into the first nanoparticle is a source of mechanical energy.

Abstract:
The invention relates to plastic bags and sack for use especially in the food and pharmaceutical industries. The bag (2) comprises inner and outer bag sections (4, 14) which are joined at least at an upper portion in a manner which allows them to be separated when required, such as by heat sealing. The outer bag section (14) may be provided with a mouth (10) through which the inner bag section can be withdrawn when required. Alternatively, the outer bag section may be peeled away from the inner bag section. The inner bag section is heat sealed after filling with contents to retain the contents in the inner portion. The heat sealing step also serves to secure the bag sections together as above. The inner bag section is preferably provided with a closeable mouth (132) separate from the end by which it is filled, through which the contents may be dispensed.
Abstract:
An implantable nuclear magnetic resonance spectrometer comprised of a first input lead and a second output lead, wherein each of said first input lead and said second output lead comprise a photonic lead (585).
Abstract:
The invention is based on the discovery of a new class of heterocyclic compounds having, for example, antibacterial properties. The D-Ala-D-Ala ligase enzyme is a critical pathway enzyme in the bacterial cell-wall synthesis. The compounds can bind to and inhibit the enzyme D-Ala-D-Ala ligase. The new compounds' activity combined with their ability to cross bacterial cell membranes makes them suitable for use as antibacterial drugs or other antibacterial applications.
Abstract:
A detection device containing a hybrid nucleic acid assembly. The device contains a nucleic acid polymer, a first complementary oligonucleotide annealed to a first consensus sequence on the nucleic acid polymer, a second complementary oligonucleotide annealed to a second consensus sequence on the nucleic acid polymer, a first nanoparticle conjugated with the first complementary oligonucleotide, a second nanoparticle conjugated with the second complementary oligonucleotide, means for introducing energy into the first nanoparticle, means for withdrawing energy from the second nanoparticle, means for detecting the withdrawal of energy from the second nanoparticle, and means for determining a physical property of the nucleic acid polymer while energy is introduced into the first nanoparticle.
Abstract:
A flow cytometer (44) containing a device for sampling cellular material within a body, comprising a detector (86), controller (88), light source (84) and injector (96). The flow cytometer (44) is adapted to mark cells within bodily fluid with a marker to produce marked cells, to analyze the marked cells, to sort the cells within the bodily fluid to produce sorted cells, and to maintain the sorted cells in a viable state.
Abstract:
A flow cytometer (300) containing a device for sampling cellular material (306) within a body. The flow cytometer is adapted to mark cells within bodily fluid (306) with a marker to produce marked cells, to analyze the marked cells, to sort the cells within the bodily fluid to produce sorted cells, to maintain the sorted cells in a viable state, and to remove the marker from the marked cells. Two marker removal devices (320, 324) are used in the flow cytometer.
