    摘要: Improved methods and apparatus for particle precipitation and coating using near- or supercritical fluid conditions are described. A fluid dispersion having a continuous phase dispersant and at least one precipitatable substance therein is contacted with a supercritical fluid (SCF) antisolvent so as to generate focused high frequency antisolvent sonic waves, breaking up the dispersion into extremely small droplets; the enhanced mass transfer rates between the droplets and the antisolvent causes precipitation of very small particles on the order of 0.1-10 .mu.m. In coating processes, a turbulent fluidized flow of core particles is created using an SCF antisolvent in an enclosed zone. The core particles are contacted therein at near- or supercritical conditions by a fluid dispersion containing a dispersant together with a precipitatable substance. The antisolvent depletes the dispersant and the substance is precipitated onto the fluidized core particles. In another aspect of the invention, a process for preparing and administering a medicament using only a single container is provided. In such method, a fluid dispersion having a dispersant with the medicament therein is contacted with an antisolvent at near- or supercritical conditions within a use container, so as to directly precipitate small particles of the medicament in the container. The antisolvent is then removed and the use container is sealed with the medicament particles therein. Thereafter, dose(s) of the medicament can be withdrawn from the use container and administered to a patient.

    摘要: The invention describes a method for extracting DNA from a sample. It involves contacting a sample with a separation reagent which permits differentiated solvation of DNA and protein. By adding a gel polymer, such as a silical gel polymer to the mixture of sample and separating reagent followed by agitation via, e.g., centrifugation, the DNA and protein are separated, with the gel acting as a block to prevent contamination of the DNA phase by the protein. Higher yields of DNA are obtained as compared to methodologies where the gel is not used. Additionally, the problems associated with the physical contact of the solvents, which are frequently carcinogens, are avoided. Also taught are kits which can be used in connection with the inventive method.

    摘要: A method of substantially decreasing the shortening content normally required in chemically leavened wheat flour based doughs or batters which comprises incorporating into the dough or batter in lieu of the shortening omitted, from about 0.1 to 3% by weight, based upon the flour content therein, of an additive selected from the group consisting of the sodium and calcium salts of acyl lactylates of C14-C22 fatty acids. The preferred additives are sodium stearoyl lactylate and calcium stearoyl lactylate, each being utilized at a concentration of about 0.5% by weight. In optional procedures, a protein supplement such as soy flour can be added to the dough or batter products without noticeably affecting the appearance and taste characteristics of the finished product.

    摘要: A method of treating amyotrophic lateral sclerosis (ALS) is provided to extend life expectancy in a subject. The method can include administering the ketamine to a subject having ALS such that the subject has an extended life expectancy compared to life expectancy of the subject prior to being administered the ketamine. The extended life expectancy is determined by the subject having a first progression rate of ALS prior to being administered ketamine and a second progression rate of ALS after being administered ketamine. The first progression rate is faster than the second progression rate such that the progression of ALS in the subject is slowed by the ketamine.

    摘要: This disclosure generally relates to aerial vehicles that may convert from hover-mode to missile-mode flight and back via body tilt for efficient flight and can strike wires such that neither the wires nor the aircraft are damaged, and divergence is prevented. This includes an aerial vehicle having an elongate fuselage having a nose tip, a plurality of engines connected to the fuselage, and at least three protective members connected substantially near the nose tip of the fuselage longitudinally beyond the plurality of engines.
