摘要:
A system for collecting, growing, and analyzing biological specimens that may present a health threat. The system includes separate modules for specimen collection, sample isolation, and sample analysis that can be interconnected to safety process, culture, and analyze and unknown specimen. A decapitation module allows a user to safely collect a swab tip containing an unknown sample and transport the sample to a culture module where the sample can be washed from the swab tip and isolated in a cuvette for growth and analysis. The culture module may be coupled to a base station that can provide mixing, heating and cooling, as well as optical and spectral analysis.

A three component system for repairing critically sized bone defects having a first shape memory polymer (SMP) component formed as a scaffold that fills the defects, a second SMP component formed as a restricting sleeve that stabilizes and supports osseointegration and osteoconduction, and a third SMP component formed as a two-dimensional cell culture substate for engineering periosteal grafts.
摘要:
The present invention relates to a waterborne shape memory polymer comprising structural units, wherein each structural units comprise: a switching segment comprising a semicrystallme or amorphous polymer; a chargeable unit comprising a cationically or anionically chargeable group; and a cross-linking unit comprising a monomer, wherein said cross-linkable unit connects said switchable segment to said chargeable unit, and wherein said waterborne shape memory polymer is dispersible in water. The present invention also relates to a waterborne polymer coating materials derived from the same.
摘要:
System and method for loading the front line anticancer drug, doxorubicin (DOX) onto DNA-capped gold nanoparticles whose duplex DNA has been designed for specific DOX intercalation. Since each AuNP contains about 108 high affinity drug sites, this design allows for a high local DOX concentration on the particle. Drug binding was confirmed by monitoring the increase in DNA melting temperature, the shift in the plasmon resonance maximum, and the increase in the NP hydrodynamic radius as a function of [DOX]/[DNA] ratio. The feasibility of the nanoparticles as a drug delivery system was demonstrated by showing that particle-bound DOX could be transferred to a target DNA.

摘要:
The present invention relates to an isolated antigen from Streptomyces coelicolor that is useful for developing, inter alia, vaccines against pathogenic bacteria of humans and animals. The present invention also relates to vaccines and antibodies developed using the isolated antigen. The present invention also relates to methods of using the antigen, vaccines, and antibodies of the present invention to detect, treat, and prevent infection and diseases associated with pathogenic bacteria.
摘要:
Embodiments of the invention relate to a branched or multichain nucleic acid switch adapted to switch from a first conformation to a second conformation upon ligand binding. The switch includes a probe strand, P, which includes the ligand binding domain; a switching framework which includes a cover strand (C), and a tether that holds P and C together and a signaling apparatus. Some embodiments include a toggle strand (T) where now the tether holds P, C, T, and the signaling apparatus together. As the switch changes between the first and second conformations; the signaling apparatus reports the state of the switch. The signaling entity is typically a lumiphore and a quencher located along the switching framework. Nucleic acid switches have applications in real time assays for diverse agents including infectious agents, environmental toxins, and terrorist agents, as well as screening' methods for such agents. Further applications are found for nanoelectronics, nanofabrication and nanomachines.
摘要:
An ear muffler device (10) suitable for coupling to the entrance of the ear canal of a person to reduce the level of ambient noise in the ear canal. The device includes a muffler tube (12) of appropriate dimensions sufficient to isolate the ear canal from ambient air and having an inner cross-sectional area of at least approximately 1.15cm so as to substantially reduce the acoustic impedance at the entrance of the ear canal over a wide area of audible sound frequencies. A connecting tube (18) for attachment to the ear canal is coupled to the ear muffler tube (12). Resilient sealing means (20) adapted to seal the connecting tube (18) to the ear canal are attached to the open end of the connecting tube (18). The device further includes means (24) for securing it in the ear. A sound source isolated from ambient air may be attached near the end of the muffler tube (12).
