摘要:
The invention is based on the discovery of methods for purification of an acid active hyaluronidase found in human plasma (hpHAse), including both biochemical and immunoaffinity purification methods. The method of immunoaffinity purification of the invention is based on the discovery of a method for identifying antibodies that specifically bind native hpHAse (anti-native hpHAse antibodies), and anti-native hpHAse antibodies identified by this screening method. The invention also features an assay for sensitive detection of HAse activity using biotinylated hyaluronic acid (bHA). Purification and characterization of hpHAse lead to the inventors' additional discovery that hpHAse is encoded by the LuCa-1 gene, which gene is present in the human chromosome at 3p21.3, a region associated with tumor suppression. The invention additionally features methods of treating tumor-bearing patients by administration of hpHAse and/or transformation of cells with hpHAse-encoding DNA.

摘要:
The present invention is based on the purification and sequencing of isozymes of plasma hyaluronidase (pHAse) found in urine. Specifically, urine contains two hyaluronidases (HAses): 1) a 57 kDa HAse that is apparently the same as the 57 kDa HAse found in plasma; and 2) a 45 kDa HAse, which is found in urine but not plasma. The smaller urine isozyme is composed of two disulfide-linked polypeptides produced by endoproteolytic cleavage of the 57 kDa isoform. The present invention thus features a urinary hyaluronidase (uHAse) polypeptide and nucleotide sequences encoding a Chain A polypeptide and a Chain B polypeptide, the two polypeptides of which uHAse is composed. In a particular aspect, the uHAse is a human uHAse (huHAse), preferably a huHAse composed of the Chain A and B polypeptides having SEQ ID NOS: 2 and 4, respectively. In related aspects the invention features polynucleotide sequence encoding Chain A and Chain B polypeptides, preferably having the sequences of SEQ ID NOS: 1 and 3, respectively. In addition, the invention features polynucleotide sequences that hybridize under stringent conditions to SEQ ID NOS: 1 and 3. In related aspects the invention features expression vectors and host cells comprising polynucleotides that encode uHAse polypeptide Chains A and B. The present invention also features antibodies that bind specifically to uHAse, and methods for producing uHAse.

摘要:
Tongs for manipulating shish-kebob on a barbeque grill, the tongs having two arms, the two arms being in parallel relationship at an insulated handle end which includes the pivot point at one end, the arms diverging at the opposing end of the handle end, to form two opposing spaced apart arms having kebob engaging ends, each end having an aperture there through, the apertures engaging the ends of the skewer, the tongs then being compressed so that the kebob engaging ends engage the outer food items on the skewer preventing their rotation so that the kebob may be either flipped for even cooking on the opposing side, or removed from the grill for consumption without endangering the fingers of the user.
摘要:
A method for producing a biomarker indicative of a repetitive head injury in a subject using a magnetic resonance imaging (MRI) system is provided. Two-dimensional spectroscopic data is acquired from a subject using an MRI system. From the two-dimensional spectroscopic data, a two-dimensional spectrum is produced. The two-dimensional spectrum contains spectral information indicated by a first spectral dimension and a second spectral dimension. Such a two-dimensional spectrum may include diagonal peaks and off-diagonal, or cross-peaks. In such an instance, each cross peak may indicate, for example, scalar coupling between the two protons it connects on the diagonal. However, depending on the type of method used, different types of coupling may also be present. Using the two-dimensional spectrum, a biomarker indicative of repetitive head injury in the subject is identified, and may be used to produce a report indicating a status or regression of a neurological dysfunction.
