Abstract:
The invention is directed to methods of screening immunogenic viral like particles and related immunogenic compositions and diagnostic techniques. In one embodiment, the invention provides methods of screening immunogenic viral like particles containing peptides corresponding to epitope regions of a wide variety of pathogens, including viruses, bacteria, parasites, and microbes. Non-infectious antigens and allergens of interest can also be screened as described herein. Immunization, therapeutic and diagnostic applications are also described for the compositions and methods according to the invention. In another embodiment, the invention provides novel methods of identifying a cryptic neutralizing epitope and related vaccines, constructs, and libraries. In some embodiments, these methods use high-throughput formats that are facilitated by in silica or in vitro steps.
Abstract:
The invention provides methods of treating nitric oxide/cGMP pathway-cell adhesion disorders and related pharmaceutical compositions, diagnostics, screening techniques and kits. In one embodiment, the invention relates to a method for down-regulating alpha4beta1-integrin affinity and inhibiting and reversing adhesion formation in patients or subjects in need using a nitric oxide donor.
Abstract:
Novel catalytic materials and methods for producing the same are shown and described. The present disclosure provides catalytic materials formed from producing an alloy of an oxophilic metal and a metal having electro-oxidative activity using spray pyrolysis. The present disclosure further provides methods and mechanisms for both detecting and removing hydrazine from a system.
Abstract:
A dry powder delivery device may be configured to provide micronized dry powder particles to airways of a user. The device may include a cylindrical container delimiting a chamber containing at least one magnetically- responsive object, a motor external to said chamber, a magnet external to the chamber and rotatably coupled with the motor, and an outflow member configured to direct airflow to a user. The magnetically-responsive object may be coated with micronized dry powder particles, and the motor may be operable to rotate the magnet about an axis. Rotation of the magnet creates a magnetic field that causes the magnetically-responsive object to move in response to the magnetic field and collide with a side wall of the container to deaggregate the dry powder particles and aerosolize the dry powder in the chamber.
Abstract:
We describe ultra-high throughput polony genome sequencing that can permit, for example, generating raw data to re-sequencing the human genome in about one week (including library prep and sequencing) at a reasonable cost. The methods described herein include one or more of the following: (1) increasing polony sequencing read length, (2) improving library construction and emulsions protocols, (3) increasing bead density and/or moving to alternative clonal amplication strategies (other than emulsion PCR or ePCR), (4) extending software capabilities to allow SNP calls from our new sequencing raw data, (5) Dual Primer Emulsion PCR, and (6) diagnostic method exploiting one or more of the foregoing.
Abstract:
The invention provides methods of treatment that prevent the onset of Mesial temporal lobe epilepsy (TLE) in a subject, or which reduce the severity of TLE in a subject, by administering a NKCCl inhibitor to the subject after the subject has suffered from an insult known to precipitate TLE.
Abstract:
A system and methods for imaging a patient organ. The system includes a MRI imaging apparatus communicating with a memory and processor. The method aligns the organ with a standardized organ, and includes a step of spatially normalizing the standardized organ to the patient organ. The method also provides optimized slices of the standardized organ and translates optimized slices of standardized organ into optimized slices of the patient organ. The method images the patient organ according to the optimized slices of the patient organ.
Abstract:
We describe methods for synthesis and formulations of stable elastomeric negative acoustic contrast particles with controllable compressibility and density. These elastomeric negative acoustic contrast particles have a density/compressibility ratio that is less than that of water and therefore exhibit negative acoustic contrast under acoustic radiation exposure. This negative acoustic contrast allows our elastomeric negative acoustic contrast particles to be acoustically manipulated (e.g. separated) differently from other components (e.g. cells) within an aqueous solution. This disclosure also describes methods for biofunctionalization of the elastomeric negative acoustic contrast particles and as an example their use as platforms for bioassays. Potential applications of these elastomeric negative acoustic contrast particles include sensitive bioassays based on acoustic flow cytometry and other types of techniques that utilize acoustic fields, including ultrasound imaging and ultrasound triggered drug delivery.
