Title: Bioprocess for preparing 7-adca
Inventor: CONDER MICHAEL J
IPC: C12N9/00
Filed: 1992-09-10
Granted: 1998-11-24
Abstract: An important intermediate for preparing cephalosporin antibiotics, 7-aminodesacetoxy cephalosporanic acid (7-ADCA), is prepared by a novel bioprocess in which a transformed Penicillium chrysogenum strain is cultured in the presence of an adipate feedstock to produce adipoyl-6-APA (6-amino penicillanic acid); and the in situ expression of an expandase gene, e.g., from Streptomyces clavuligerus, with which the P. chrysogenum has been transformed, converts the adipoyl-6-APA by ring expansion to adipoyl-7-ADCA.  The final product, 7-ADCA, is then prepared by cleavage of the adipoyl side chain using an adipoyl acylase.  The entire synthesis, accordingly, is carried out using bioprocesses, and is efficient and economical.

Granted: 1998-04-14
Abstract: A method and apparatus is provided for removing water accumulated at the cathode (22) of an electrochemical fuel cell incorporating a solid polymer ion exchange membrane (12). Liquid water accumulated at the cathode can be removed by maintaining a partial pressure of water vapor in the hydrogen-containing gas supply below the saturation pressure of water vapor therein such that water accumulated at the cathode is drawn by a concentration gradient toward the anode (20) across the membrane and is absorbed as water vapor into the hydrogen-containing gas supply between the inlet and the outlet. In one embodiment, the partial pressure of water vapor in the hydrogen-containing gas supply is maintained below the saturation pressure of water vapor therein by imparting a pressure drop between the inlet and the outlet sufficient to draw water accumulated at the cathode toward the anode. In another embodiment, the partial pressure of water vapor at the inlet of the hydrogen-containing gas supply is maintained at less than the saturation pressure of water vapor therein. Liquid water accumulated at the cathode can also be removed by maintaining a partial pressure of water vapor in the oxygen-containing gas supply below the saturation pressure of watervapor therein such that water accumulated at the cathode is drawn by a concentration gradient and is absorbed as water vapor into the oxygen-containing gas supply between the inlet and the outlet. Liquid water accumulated at the cathode can also be removed by absorbing water vapor into both the hydrogen-containing gas supply and the oxygen-containing gas supply.

Abstract: A differential conductivity recirculation monitor quantitatively determines the degree of recirculation in a fistula by comparing the conductivity of blood entering the fistula to the conductivity of blood being withdrawn from the fistula.  A discrete quantity of a high conductivity marker fluid is injected into the blood entering the fistula, altering the conductivity of the blood entering the fistula.  The altered conductivity blood enters the fistula and, if recirculation is present, co-mingles with blood in the fistula, altering the conductivity of the blood ion the fistula in proportion to the degree of recirculation.  Blood withdrawn from the fistula has an altered conductivity related to the degree of recirculation.  Quantitative values of the conductivity of the altered conductivity blood entering the fistula and the conductivity of the blood being withdrawn from the fistula are measured and a difference determined.  The determined difference between the conductivities is used to determine a quantitative measurement of the degree of recirculation in the fistula.

Abstract: A cardiac pacemaker signal processing circuit adapted to obtain an evoked ECG signal.   The circuit senses the electrical signals of the ring and tip electrodes in the unipolar mode from the bipolar lead after the electrical pacing stimulus has been applied to contract the ventricle of the heart.  The residual oppositely polarized potentials at the ring and tip electrode, as well as the sensed evoked ECG signals, are added together to cancel out the opposing residual potentials, but to add the common polarized ECG signal.    Thus,  a  high  quality  evoked  ECG  signal  is obtained, free of the residual potentials, and subsequently utilized by R-wave detection circuits for sensing the QRS complex.   The  circuit  includes  compensating  signal processing  circuits  to  provide  time  domain  signal processing weighting functions to match exponential time delay  of  the  tip  and  ring  electrodes,  and  includes amplitude  adjusting  compensation  as well.    Thus,  the absolute amplitudes of the opposite polarized residual potentials will be adjusted to be equal, are summed, and canceled or nulled at the appropriate time in the time domain.  Both biphasic and triphasic pace pulse techniques are not required, the pace pulse amplitude can he reduced to extend the battery life of the pacemaker.  Further, the post  pace  re-charging  cycle  is  only  interrupted  and undertaken passively to, again, reduce current drain on the battery.  Classic R-wave detection circuits are adaptable to the signal processing circuit of the present invention.
