Filed:

Apr 29, 2005

Appl. No.:

11/117696

Inventors:

Lawrence Jason Berger - New York NY, US

Justine Elizabeth Roberts - Brooklyn NY, US

Assignee:

Wireless Generation, Inc. - New York NY

International Classification:

G09B 3/00

US Classification:

434322, 434156, 434365, 434319, 434308

Abstract:

A real-time observation assessment system includes an assessment application that enables an assessor to administer a probe to a student, and to capture responses of the student, and to automatically score the captured responses. The assessment system includes a user interface of the assessment application. The user interface includes a first area of the user interface that displays a character sequence that is divided into multiple segments, where at least two of the multiple segments of the character sequence are separately selectable and a second area of the user interface that is divided into multiple segments corresponding to each segment of the character sequence in the first area, where each segment in the second area is separately selectable to enable capturing of different combinations of student responses reflecting selection of one or more of the segments in the second area. A scoring module enables a score to be calculated based on the selected segments according to scoring rules for the probe.

Appl. No.:

6/435581

Inventors:

David Stevenson - Scarsdale NY

Assignee:

USV Pharmaceutical Corporation - Tarrytown NY

International Classification:

C07C10352
C08L 8900

US Classification:

525 5411

Abstract:

The yield of peptide synthesis processes of the type in which a protected intermediate resin peptide of the formula Resin--CH. sub. 2 --O--Phe--X, Resin--CH. sub. 2 --O--Gly--X, Resin--CH. sub. 2 --O--Ala--X, or Resin--CH. sub. 2 --O--Leu--X is deprotected, and successively protected amino acids are coupled to the resin peptide and deprotected, is increased significantly by deprotecting the first residue with trifluoroacetic acid and deprotecting the other residues with hydrogen chloride.

Assignee:

USV Pharmaceutical Corp. - Ft. Washington PA

International Classification:

C07K 100

US Classification:

530333

Abstract:

Peptides, such as calcitonin, having two cysteine residues connected by a disulfide bond are prepared by a process which includes the step of cyclizing the cysteines at a pH of 8. 5 to 9. 0, and a concentration of 0. 4 to 1. 8 mg of peptide per ml of solution. These novel conditions produce rapid cyclization with an unforeseen improvement in yield.
