Blood plasma is a yellowish liquid component of blood that holds the blood cells in whole blood in suspension. It is the liquid part of the blood that carries cells and proteins throughout the body. It makes up about 55% of the body's total blood volume. It is the intravascular fluid part of extracellular fluid (all body fluid outside cells). It is mostly water (up to 95% by volume), and contains dissolved proteins (6–8%) (e.g. serum albumins, globulins, and fibrinogen), glucose, clotting factors, electrolytes (Na⁺, Ca²⁺, Mg²⁺, HCO₃⁻, Cl⁻, etc.), hormones, carbon dioxide (plasma being the main medium for excretory product transportation) and oxygen. It plays a vital role in an intravascular osmotic effect that keeps electrolyte concentration balanced and protects the body from infection and other blood disorders.

Non-invasive detection of fetal genetic traits
InactiveUS20050164241A1Facilitates non-invasive detectionComponent separationOther chemical processesPregnancyNon invasive
Blood plasma of pregnant women contains fetal and (generally>90%) maternal circulatory extracellular DNA. Most of said fetal DNA contains ≦500 base pairs, said maternal DNA having a greater size. Separation of circulatory extracellular DNA of <500 base pairs results in separation of fetal from maternal DNA. A fraction of a blood plasma or serum sample of a pregnant woman containing, due to size separation (e.g. by chromatography, density gradient centrifugation or nanotechnological methods), extracellular DNA substantially comprising ≦500 base pairs is useful for non-invasive detection of fetal genetic traits (including the fetal RhD gene in pregnancies at risk for HDN; fetal Y chromosome-specific sequences in pregnancies at risk for X chromosome-linked disorders; chromosomal aberrations; hereditary Mendelian genetic disorders and corresponding genetic markers; and traits decisive for paternity determination) by e.g. PCR, ligand chain reaction or probe hybridization techniques, or nucleic acid arrays.

A deposition system and method of operating thereof is described for depositing a conformal metal or other similarly responsive coating material film in a high aspect ratio feature using a high density plasma is described. The deposition system includes a plasma source, and a distributed metal source for forming plasma and introducing metal vapor to the deposition system, respectively. The deposition system is configured to form a plasma having a plasma density and generate metal vapor having a metal density, wherein the ratio of the metal density to the plasma density proximate the substrate is less than or equal to unity. This ratio should exist at least within a distance from the surface of the substrate that is about twenty percent of the diameter of the substrate. A ratio that is uniform within plus or minus twenty-five percent substantially across the surface of said substrate is desirable. The ratio is particularly effective for plasma density exceeding 1012 cm−3, and for depositing film on substrates having nanoscale features with maximum film thickness less than half of the feature width, for example, at ten percent of the feature width.

Disclosed herein are surface coatings for plasma components that have the benefit of being robust against chemical and plasma physical attack in aggressive (e.g., fluorine-based) plasma environments. The coatings also provide low plasma surface recombination rates for active oxygen, nitrogen, fluorine, and hydrogen species when compared with other known surface treatments. The coatings can be applied to any plasma system component not requiring etching or plasma cleaning including but not limited to materials like quartz, aluminum, or anodized aluminum. Additionally, the efficiency of the system is increased by applying a non-reactive coating to system components thereby increasing the flow of excited plasma species to the plasma chamber of the system.

Size-based analysis of fetal DNA fraction in maternal plasma
ActiveUS20130237431A1Health-index calculationMicrobiological testing/measurementAbnormal tissue growthBlood plasma
A fractional concentration of clinically-relevant DNA in a mixture of DNA from a biological sample is determined based on amounts of DNA fragments at multiple sizes. For example, the fractional concentration of fetal DNA in maternal plasma or tumor DNA in a patient's plasma can be determined. The size of DNA fragments in a sample is shown to be correlated with a proportion of fetal DNA and a proportion of tumor DNA, respectively. Calibration data points (e.g., as a calibration function) indicate a correspondence between values of a size parameter and the fractional concentration of the clinically-relevant DNA. For a given sample, a first value of a size parameter can be determined from the sizes of DNA fragments in a sample. A comparison of the first value to the calibration data points can provide the estimate of the fractional concentration of the clinically-relevant DNA.

A composition for controlled release of an opioid from a pharmaceutical composition, the method comprises controlling the release of at least one opioid into an aqueous medium by erosion of at least one surface of a pharmaceutical composition comprising I) a matrix composition comprising a) polymer or a mixture of polymers, b) an opioid and, optionally, c) one or more pharmaceutically acceptable excipients, and (i) a coating. The matrix composition has a conus-like shape so the surface area exposed to the aqueous medium increases at least during initial erosion of the matrix composition, and the dissolution of the opioid-when tested in a Dissolution Test as described herein with or without application of sinkers-results in a zero order release of at least 80% of the opioid contained in the composition. Such compositions are especially suitable for controlled release of an opioid to obtain a delayed pead concentration and a prolonged therapeutically effective plasma concentration upon oral administration. Once or twice daily administration is possible. The matrix typically comprises PEO and the active substance is typically an opioid such as morphine or a glucuronide thereof.
