Abstract: A process for the synthesis of an Exochelin comprising the steps of generating L-N-[(2-benzyloxy-(benzoyl)]serine or L-N-[2-benzyloxy(benzoyl)] threonine, creating L-N-t-Boc-.epsilon.hydroxynorleucine and reacting same to produce L-N-Boc-.epsilon.-bromonorleucine trimethylsilylethyl ester, providing a dicarboxylic acid and forming an O-benzyl methyl hydroxamate from the dicarboxylic acid, coupling the O-benzyl methyl hydroxamate with the L-N-Boc-.epsilon.-bromonorleucine trimethylsilylethyl ester to give an L-N2-Boc-N6-methyl,N6-(benzyloxy) lysine 2-trimethylsilylethyl ester which incorporates the dicarboxylic acid as modified above, removing the N-tert-butoxycarbonyl protecting group from the L-N2-Boc-N6-methyl,N6-(benzyloxy) lysine 2-trimethylsilylethyl ester to yield a substituted lysine, and coupling the same with the L-N-[2-benzyloxy(benzoyl) serine or -threonine to yield a 2-trimethyl silylethyl ester of dibenzyl Exochelic acid, transforming the 2-trimethyl silylethyl ester of dibenzyl Exochelic acid to dibenzyl Exochelic acid , preparing benzyl epi-cobactin, forming an ester bond between the dibenzyl Exochelic acid and benzyl epi-cobactin to form an intermediate, and, hydrogenolytically removing three benzyl groups from said intermediate, resulting in the synthesized Exochelin. More particularly, a synthesis for Exochelin 786SM (R) is disclosed wherein the dicarboxylic acid is suberic acid and the serine form is utilized.

Title: System for neonatal nursing development
Inventor: GOLDFIELD EUGENE C
IPC: A61J17/00
Filed: 1999-08-04
Abstract: In a system for diagnosing or monitoring sucking/swallowing/breathing competence of an impaired neonate or post-operative infant, a processor (7, 40) receives a signal from a breath sensor (4, 5, 45), and develops an outpu t for intraoral tactile or flow control feedback. In a feeding or monitoring embodiment, the processor applies the signal to control a liquid feeding val ve (37) which supplies nutrients through a feeding nipple (32). In an embodimen t specifically adapted for manual feeding, monitoring or intervention, the processor displays a waveform indicative of the breath or air flow sensor output, and a manually operated pressure bulb (1) is provided to allow a nur se or care giver to apply a rhythmic muscular pressure stimulus via a feeding o r surrogate nipple (20a) in a manner visually synchronized with the displayed breath activity. Preferred frequencies and phased coordination with the brea th cycle may facilitate the development of competence and the coordination or linkage of the three sensorimotor areas. The system may also provide medical  records of sensed events, and trigger an alarm when it detects a dangerous condition.

Abstract: A communication connector includes a housing with an opening for receiving a mating connector. First and second pairs of terminal contact wires are supported in the housing, and each pair forms a different signal path. The terminal contact wires have base portions, free ends, and intermediate co-planar contact portions that establish points of electrical contact with corresponding terminals of a mating connector. First and second pairs of elongated, parallel capacitor plates are fixed at corresponding free ends of the contact wires. The plates of each pair of capacitor plates capacitively couple an associated terminal contact wire of the one pair of contact wires, with an associated terminal contact wire of the other pair of contact wires.  The two pairs of capacitor plates extend in a length direction that is substantially parallel to the plane of the contact portions of the terminal contact wires. In the disclosed embodiment, the first and the second pairs of parallel capacitor plates extend perpendicular to the contact wires, and are aligned in planes orthogonal to one another.

Title: In vitro macromolecule biosynthesis methods using exogenous amino acids and a novel atp regeneration system
Inventor: KIM DONG-MYUNG
IPC: C12N9/10
Filed: 2000-03-15
Abstract: Compositions and methods are provided for the enhanced in vitro synthesis of polypeptides. In order to improve the performance of in vitro protein synthesis reactions, metabolic inhibitors, or manipulation of a source organism, is used to diminish or avoid the action of enzymes responsible for undesirable amino acids production or depletion. A homeostatic system may be used for production of ATP, where the required high energy phosphate bonds are generated in situ, e.g. through coupling with an oxidation reaction. The homeostatic energy source will typically lack high energy phosphate bonds itself, and will therefore utilize free phosphate in the reaction mix during generation of ATP. The homeostatic energy source is provided in combination with an enzyme that catalyzes the creation of high energy phosphate bonds and with an enzyme that can use that high energy phosphate bond to regenerate ATP.
