Medicine & Biotechnology

A disposable product used to stabilize rolling veins and bring small veins into position to facilitate needle insertion. Needle insertion is used for transfusions, to draw blood samples, and for variety of other medical necessities. Many patients have either/or both small veins or veins that roll under the skin. Either of these characteristics has the tendency to complicate the process of sticking the needle in.

A system and a method for providing a determination of predicted cognitive performance of an individual preferably based the time of day and on factors including sleep history based on activity data from an actigraph and the individual's activities. The system and the method provide a numerical representation of the predicted cognitive performance. Both may be used to optimize the work schedule of the actigraph wearer to maximize the cognitive capacity during working hours.

This invention relates to estimating the amount of blood flowing to the tissues of the kidney. More particularly, the invention is related to analyzing obtained power Doppler ultrasound images taken of the kidney and even more specifically of the kidney cortex tissue to produce a numerical value that correlates to the blood flow.

A recombinant protein encompassing the complete envelope glycoprotein and a portion of the carboxy-terminus of the membrane/premembrane protein of dengue 2 virus was expressed in baculovirus as a protein particle. The recombinant protein particle was purified and found to provide protection against lethal challenge with dengue 2 virus in mice.

The invention here relates to recombinant DNA constructs which comprise a Venezuelan equine encephalitis replicon vector and at least one DNA fragment encoding a protective antigen from the Marburg virus. The DNA constructs are useful for inducing an immune response which is protective against infection with Marburg virus in nonhuman primates.

In accordance with the present invention, a device for acquiring contoured human body surface vibration signals is provided.

The present invention provides vaccine compositions of attenuated dengue-2 virus. More specifically, the attenuated virus is produced by serial passage in PDK cells. The invention also provides methods for stimulating the immune system of an individual to induce protection against dengue-2 virus by administration of attenuated dengue-2 virus.

The present invention relates to a device for detecting cancer in human tissue. The device comprises an acoustic array shaped to conform to and surround a portion of the human anatomy and a material for acoustically coupling the acoustic array and the human anatomy portion. The acoustic array is formed from a plurality of doubly curved segments. Each segment is formed by a piezoelectric ceramic polymer composite material with an acoustic element pattern formed on one surface via the selective deposition of a conductive material.

Methods and apparatus for measuring the millimeter or submillimeter wave absorption spectra in a sample of DNA molecules are provided.

Using the nontoxic heavy chain fragment from botulinum neurotoxins A-G, compositions and methods of use in inducing an immune response which is protective against intoxication with botulinum in subjects is described.
