Fluorescence Scanning System for Improvement of Analytical Ultracentrifugation

This technology includes improvements in the fluorescence scanner to increase efficiency. This method works by eliminating the need to radially slide the optical assembly during scanning, instead using a galvanometric mirror deflecting a laser beam to different positions in the sample. This allows the scanner to be incorporated into existing commercial analytical ultracentrifugation (AUC) systems with minimal modifications.

Micropatterning of Extracellular Matrix Proteins Using Microphoto-ablation Of Poly vinyl Alcohol (PVA) Monolayers

Available for licensure and commercial development is a micro-photoablation (µPA) method used as a micro-patterning technique to attach ECM proteins or other biological molecules to specified locations. Advantages of this photolytic technique are that it: (a) is stampless, (b) allows for flexible pattern generation to the submicron level, (c) allows for live cell fluorescence imaging, retains cell viability, and (d) allows the use of multiple proteins.

A Method to Guide Protocol Development for Magnetic Resonance Thermometry

This technology includes tools to guide optimization of thermometry imaging/post-processing protocols. Proton Resonance Frequency (PRF) thermometry is a widely used Magnetic Resonance Imaging (MRI) based technique to monitor changes in tissue temperature in response to thermal therapy. The use of PRF thermometry with thermal therapy procedures is indispensable to ensure delivery of desired thermal dose to the target tissue, and to minimize unintended damage to the normal tissue.

Personal Air Sampler for Collecting Airborne Aerosol Particulates for Molecular Analysis by Size

This invention consists of a sampling apparatus that utilizes one or more cyclone separators to collect airborne particles from the atmosphere. The apparatus not only separates out aerosols from the atmosphere, but also serves as a collection tube for aerosol particles. Through its unique design, this CDC-developed apparatus is able to use the centrifugal force of the air flow on aerosolized particles forcing them to separate by size. Since the sample is collected directly in a microcentrifuge tube, in situ analysis of the ambient particulates can be performed.

Nucleic Acid Detection of the Fungal Pathogen Histoplasma capsulatum from Clinical and Environmental Samples

This invention relates to detecting Histoplasma capsulatum by PCR using oligonucleotide probes specific for the fungus. Histoplasmosis is a mycotic infection of varying severity, usually localized in the lungs. Caused by H. capsulatum, infections are usually symptomatic but can develop into chronic disease, especially in immunocompromised individuals.

Device to Measure Muscle Contractile-Relaxant and Epithelial Bioelectric Responses of Perfused, Intact Tracheal Airways Tissue In Vitro

CDC and collaborative researchers have developed a device allowing for simultaneous measurement of smooth muscle contractile/relaxant activity and transepithelial potential difference (Vt) [or short circuit currents (Isc)] and resistance (Rt) within an intact airway in vitro. Investigation of the underlying mechanisms of lung diseases, such as asthma or cystic fibrosis, involves understanding the roles of airway smooth muscle and epithelium.

Inexpensive, Personal Dust Detector Tube/Dosimeter Operating on a Gas Detector Tube Platform

This CDC developed dust detector tube is designed to provide inexpensive, short-term, time weighted average dust exposure data feedback directly to device users. This invention operates upon a conventional gas detector tube platform and can be used with any low volume pump that can electronically measure pump back pressure. The device consists of three sections: the first defines the size of the dust and removes moisture, the second uses a filter whose pressure differential corresponds with cumulative dust loading, and a final section employs a pressure transducer.

Automated Microscopic Image Acquisition, Compositing and Display Software Developed for Applied Microscopy/Cytology Training and Analysis

Micro-Screen is a CDC developed software program designed to capture images and archive and display a compiled image(s) from a portion of a microscope slide in real time. This program allows for the re-creation of larger images that are constructed from individual microscopic fields captured in up to five focal planes and two magnifications. This program may be especially useful for the creation of data archives for diagnostic and teaching purposes and for tracking histological changes during disease progression.

Improved Acoustic Plethysmograph System for Noninvasive Measurement of Pulmonary Function

CDC researchers have developed a novel acoustic whole body plethysmograph (AWBP) that allows measurement of tidal volume in lab animals, independent of gas compression in the lung. This system provides particular advantages over the traditional whole body plethysmograph (WBP) when measuring model animals with increased gas compression due to increased airway resistance or increased acceleration in the breathing pattern.

Focused Electrostatic Collection of Aerosol Particles for Chemical Analysis by Spectroscopic Techniques

This CDC-developed technology is an aerosol preconcentration unit (APU) designed for use with spectroscopic detection techniques, including emission, Raman, or infrared spectroscopies. Most existing pulsed microplasma techniques, such as laser-induced breakdown, for aerosols rely mainly on filter-based collection and suffer from poor accuracy, precision, and detection limits and require long sample collection times.
