Title: Emergency shutdown test system
Inventor: SEBERGER STEPHEN G
IPC: F16K37/00
Filed: 2000-02-28
Abstract: An emergency shutdown system for a process control system includes an emergency shutdown (ESD) valve (12) and an associated valve actuator (18). An emergency shutdown (ESD) controller (46) provides output signals to the ESD valve in the event of a failure in the process control system.

Inventor: JOHNSON LARRY L
IPC: H02J9/06
Filed: 2003-04-07
Abstract: A power system specifically designed to provide reliable electrical power to a telecommunication facility is disclosed. The system includes a number of microturbine generators adapted to provide AC power that is then rectified to DC power by an array of rectifiers. The system is configured so that the microturbine generators are fueled initially by utility-supplied natural gas. In the event the utility-supplied natural gas fails, the system provides propane from a storage tank to fuel the microturbine generators. If both microturbine generator fuel sources fail or their fuel supply becomes exhausted, power is supplied to the rectifiers by a commercial electrical utility. The system also includes a number of hydrogen-powered proton exchange membranes that are operable to supply DC power directly to the facility if both the microturbine generators and the electrical utility fail. Finally, a number of super capacitors are coupled to the bus line directly connected to the facility in order to maintain power if it becomes necessary to switch power sources.

Title: The selective mmp-9-inhibitor rega-3g12scfv ameliorates in vivo parameters of kidney function after renal ischemia
IPC: C07K16/40
Filed: 2003-08-01
Abstract: Ischemia occurs frequently in various human pathologies and remains the leading cause of acute renal failure in adults. Physiological changes in the kidney suggest that ischemia-reperfusion injury alters the extracellular matrix.      Matrix metalloproteinases (MMPs) are key proteolytic enzymes remodeling the matrix. Recently a strong stimulation of both latent and active forms of dimeric MMP-9 and the active monomeric MMP-9 was observed in glomeruli during kidney ischemia. Our objective was to investigate the ability of REGA-3G12 to inhibit selectively MMP-9 induced in glomeruli during renal ischemia in rats. Unilateral ischemia was induced by vascular clamping (30 min) followed or not by reperfusion (60 min) and isolation of glomeruli.   REGA-3G12scFv in PBS solution was injected at a dosage of 5 mg/kg in the rat jugular vein at 1 h before ischemia. Results: Serum creatinine levels are an indicator of impaired glomerular filtration rate, an hallmark of acute renal failure. REGA-3G12 significantly prevented the increase of serum creatinine levels during the reperfusion. Gelatin zymography and Western blotting determined the activation and expression levels of gelatinases.   REGA-3G12scFv blocks the upregulation of MMP-9 expression induced by ischemia in glomeruli. MMP-9 upregulation during kidney ischemia led to degradation of tight junction zonula occludens-1 (ZO-1), an MMP-9 substrate. But, ZO-1 levels were higher in the presence of REGA-3G12 than in its absence demonstrating that both expression and in vivo activity of MMP-9 were inhibited by REGA-3G12. ProMMP-2 and MMP-2 levels were modulated by ischemia-reperfusion with similar patterns in the presence and absence of REGA-3G12 showing the specificity of REGA-3G12 action for MMP-9. In the presence of REGA-3G12, TIMP-1 was protected against proteolysis occurring during ischemia. In contrast, similar patterns of TIMP-2 were observed in the presence and in the absence of REGA-3G12 during ischemia-reperfusion. In conclusion, these data clearly demonstrate that REGA-inhibits MMP-9 activity in a living animal generating new insights about the molecular mechanisms of REGA-3G12 to specifically block MMP-9 activity and expression. These data suggest a role for specific MMP-9 inhibitors in the management of renal ischemic conditions.
