Publication number: 20110006261Abstract: Head and neck squamous cell carcinomas (HNSCC) represent a group of metastasizing tumors with a high mortality rate in man and animals. Since the biomolecule ozone was found to inhibit growth of various carcinoma cells in vitro we here applied the highly aggressive and lethal VX2 carcinoma HNSCC tumor model of the New Zealand White rabbit to test whether ozone exerts anti-tumorous effects in vivo. Therapeutic insufflation of medical ozone/oxygen (O3/O2) gas mixture into the peritoneum (O3/O2-pneumoperitoneum) at an advanced stage of tumor disease led to a survival rate of 7/14 rabbits. Six of the seven surviving rabbits presented full tumor regression and the absence of local or distant lung metastases. Insufflation of pure oxygen (O2) resulted in a survival rate of 3/13 animals accompanied by full tumor remission in two of the three surviving animals. Of the fourteen sham-treated animals only one had spontaneous tumor remission and survived.Type: ApplicationFiled: November 14, 2008Publication date: January 13, 2011Inventors: Jochen A.

Publication number: 20100264304Abstract: Vapors of relatively heavy species having molecular weights in excess of 290 amu have not been previously detected in the gas phase at ambient temperature. A method to detect them is taught here based on the use of a mass spectrometer with an atmospheric pressure source. Ions produced in detectable quantities from such heavy vapors are claimed as a new state of matter.Type: ApplicationFiled: April 4, 2007Publication date: October 21, 2010Inventors: Martinez-Lozano Pablo, Juan Fernandez de la Mora

Publication number: 20100226848Abstract: It is the purpose of this invention to present a process for producing carbon nanostructure in which the mechanism of continuous carbon nanostructure growth can be optimized and a high-quality carbon nanostructure can be produced, a catalyst for carbon nanostructure growth which is for use in the production, a raw-material gas and a carrier gas for producing the same, and an apparatus for producing the same. The process for carbon nanostructure production, in which the length of the nanostructure can be continuously controlled comprises feeding a carrier gas and a raw-material gas to a reaction chamber (4) to produce a carbon nanostructure (2) with a catalytic structure (6), wherein the concentrations of oxidation gases contained in the carrier gas and raw-material gas, such as oxygen and water (in the case of raw-material acetylene gas, minor ingredients such as DMF and acetone, which are solvents), are regulated to a moderate value.Type: ApplicationFiled: February 21, 2007Publication date: September 9, 2010Applicant: TAIYO NIPPON SANSO CORPORATIONInventors: Yoshikazu Nakayama, Takeshi Nagasaka, Toru Sakai, Osamu Suekane

Publication number: 20100224834Abstract: A method for determining a carbon content value of a hydrocarbon-containing mixture. At least one composition-dependent bulk property of the hydrocarbon-containing mixture is measured and optionally at least one non-hydrocarbon component concentration is measured with the resulting measurements used in a carbon content correlation for calculating the carbon content of the hydrocarbon-containing mixture. The carbon content may be used in a hydrogen and/or synthesis gas production process for calculating a target flow rate of steam to be combined with the hydrocarbon-containing mixture to form a mixed feed having a target steam-to-carbon ratio.Type: ApplicationFiled: May 21, 2010Publication date: September 9, 2010Applicant: AIR PRODUCTS AND CHEMICALS, INC.Inventors: Xiang-Dong Peng, Blaine Edward Herb, Matthew H.

Publication number: 20100197977Abstract: A process for purifying an acetoxylation mixture is disclosed. Allyl acetate, water, acetic acid, and from 0.1 to 10 wt. % allyl diacetate are contacted in the vapor phase with a solid acidic catalyst under conditions effective to decompose the allyl diacetate and generate an intermediate stream comprising allyl acetate, water, acetic acid, and acrolein. Acrolein is then removed from the intermediate stream, preferably by distillation, to give an allyl acetate-containing product stream. Usually, this product stream is then hydrolyzed to produce allyl alcohol. The invention includes processes in which propylene first reacts with oxygen and acetic acid in the presence of a noble metal catalyst to generate the acetoxylation mixture.Type: ApplicationFiled: February 5, 2009Publication date: August 5, 2010Inventor: Stephen H.
