Abstract: A method and system for imaging a sample. The method includes the steps of generating an ultrasonic signal, directing the signal into a sample, which signal is distorted and contains a first order and higher order component signals at first and higher frequencies respectively. The received distorted signal is processed, and an image is formed, and then displayed, from one of the higher order component signals of the received distorted signal.
Abstract: The invention provides pharmaceutical compositions comprising compounds of formula I and IV: wherein R1-R11 and A have any of the values defined in the specification, and their pharmaceutically acceptable salts. The pharmaceutical compositions are useful for inhibiting ?-lactamase enzymes, for enhancing the activity of ?-lactam antibiotics, and for treating ?-lactam resistant bacterial infections in a mammal.

Abstract: A method is provided for screening Caulobacter suitable for use as host organisms for secretion of heterologous polypeptides. Such Caulobacter have a transport protein homologous to one of the type I transport proteins known in C. crescentus. DNA constructs are also provided which code for a chimeric protein of which the C-terminus is a secretion signal of a Caulobacter surface layer protein, other than from C. crescentus. Bacterial cells containing, or which express such DNA constructs and which may secrete the resulting protein, are also provided.

Abstract: The present invention provides formaldehyde dehydrogenase genes (FLD) from methylotrophic yeasts. The FLD structural genes confer resistance to formaldehyde and are therefore useful as a selectable marker in methylotrophic yeasts. The FLD promoter sequences are strongly and independently induced by either methanol as sole carbon source (with ammonium sulfate as nitrogen source) or methylamine as sole nitrogen source (with glucose as carbon source). Induction under either methanol, methylamine or both provides levels of heterologous gene expression comparable to those obtained with the commonly used alcohol oxidase I gene promoter (PAOX1). The FLD promoter of Pichia pastoris (PFLD1)is an attractive alternative to PAOX1 for expression of foreign genes in P. pastoris, allowing regulation by carbon (methanol) or nitrogen (methylamine) source within the same expression strain.
Abstract: In accordance with the present invention, novel IL-16 antagonists, preferably peptides derived from CD4, have been isolated and synthesized. These peptides possess IL-16 antagonistic properties including the ability to selectively bind to IL-16 and inhibit IL-16-mediated biological activity. The peptides comprise specific portions of the native human CD4 receptor and variations thereof and therefore are non-immunogenic when administered to humans. The present invention also provides compositions containing at least one IL-16 antagonist peptide which can inhibit, suppress or cause the cessation of at least one IL-16-mediated biological activity in mammals, including humans. The present invention provides a method and composition for treating inflammation associated with disease states such as asthma, rheumatoid arthritis, inflammatory bowel disease (IBD) and systemic lupus (SLE) in mammals such as, for example, humans.

Abstract: A fibronectin type III (Fn3) polypeptide monobody, a nucleic acid molecule encoding said monobody, and a variegated nucleic acid library encoding said monobody, are provided by the invention. Also provided are methods of preparing a Fn3 polypeptide monobody, and kits to perform said methods. Further provided is a method of identifying the amino acid sequence of a polypeptide molecule capable of binding to a specific binding partner (SBP) so as to form a polypeptide:SSP complex, and a method of identifying the amino acid sequence of a polypeptide molecule capable of catalyzing a chemical reaction with a catalyzed rate constant, kcat, and an uncatalyzed rate constant, kuncat, such that the ratio of kcat/kuncat is greater than 10.
Abstract: The present invention has found that a series of peptides having sequences that substantially correspond to specific regions of the C-terminus of IL-16 can inhibit the activity of IL-16. The present invention has demonstrated that such IL-16-inhibiting peptides can be as short as 4 amino acids in length. Based on these discoveries, the present invention provides IL-16 antagonist peptides and the use thereof for the treatment of IL-16-mediated disorders such as certain inflammatory diseases.
