Acousto-optically modulated quantum cascade laser for high-temperature reacting systems thermometry.

We demonstrate time-resolved temperature measurements in shock-heated mixtures of carbon monoxide over a temperature range of 1000-1800 K for two pressure ranges, 2.0-2.9 atm and 7.

A Light-Emitting Diode- (LED-) Based Absorption Sensor for Simultaneous Detection of Carbon Monoxide and Carbon Dioxide.

A sensor was developed for simultaneous measurements of carbon monoxide (CO) and carbon dioxide (CO2) fluctuations in internal combustion engine exhaust gases. This sensor utilizes low-cost and compact light-emitting diodes (LEDs) that emit in the 3-5 µm wavelength range. An affordable, fast response sensor that can measure these gases has a broad application that can lead to more efficient, fuel-flexible engines and regulation of harmful emissions.

Pharmaceutical development, quality control, stability and compatibility of a parenteral lyophilized formulation of the investigational polymer-conjugated platinum antineoplastic agent AP5346.

AP5346 is a low molecular weight polymer-conjugated platinum antineoplastic agent. The lyophilized drug product has completed a phase I clinical trial. In order to guarantee a constant quality of AP5346 pharmaceutical products, quality control and analysis of the drug substance and final product were performed.

Synthesis and characterization of AP5346, a novel polymer-linked diaminocyclohexyl platinum chemotherapeutic agent.

Syntheses of the novel polymer-bound platinum-based chemotherapeutic agent poly(HPMA)-GGG-Ama=Pt=(1R,2R)-DACH, AP5346, and its precursors are reported. The method utilized in preclinical development of AP5346 is described herein. Additionally, an improved synthesis, which has shown that ion exchange resins can be removed, significantly less platinum can be used when the reaction mixture is pH-stated, and the synthesis can be performed at a higher concentration, is reported.

Modification of inflammatory response to implanted biomedical materials in vivo by surface bound superoxide dismutase mimics.

The healing response to implanted biomedical materials involves varying degrees and stages of inflammation and healing which in some cases leads to device failure. In this article, we describe synthetic methods and in vivo results of a novel surface treatment for biomedical materials involving covalent conjugation of a low molecular weight superoxide dismutase mimic (SODm), which imparts anti-inflammatory character to the material. SODm investigated in this study are a new class of anti-inflammatory drugs consisting of a Mn(II) complex of a macrocyclic polyamine ring that catalyze the dismutation of superoxide at rates equivalent to that of native enzyme.
