Vasculogenic mimicry-associated ultrastructural findings in human and canine inflammatory breast cancer cell lines.

Background: Human inflammatory breast cancer (IBC) and canine inflammatory mammary cancer (IMC) are the most lethal mammary cancers. An exacerbated angiogenesis and the existence of vasculogenic mimicry (VM) are hallmarks of these tumors. The information regarding VM and ultrastructural characteristics of mammary cell lines is scant.

Different role of COX-2 and angiogenesis in canine inflammatory and non-inflammatory mammary cancer.

Human inflammatory breast cancer (IBC) and canine inflammatory mammary cancer (IMC) are the most aggressive and fatal types of mammary cancer, and both have a very poor prognosis and low survival rate. Human IBC is characterised by exacerbated angiogenesis, lymphangiogenesis, and lymphangiotropism. Lymphangiotropism is also characteristic of IMC, but microvascular density (MVD) and lymphangiogenesis have not been previously studied in canine IMC.

Evaluation of the University of Florida lomustine, vincristine, procarbazine, and prednisone chemotherapy protocol for the treatment of relapsed lymphoma in dogs: 33 cases (2003-2009).

Objective: To evaluate the toxicity and efficacy of a modification of a previously evaluated combination of lomustine, vincristine, procarbazine, and prednisone (LOPP) as a rescue protocol for refractory lymphoma in dogs.

Design: Retrospective case series. Animals-33 dogs with a cytologic or histologic diagnosis of lymphoma that developed resistance to their induction chemotherapy protocol.

Serum concentrations of IgG, IgA, and IgM in retired racing Greyhound dogs.

Background: Greyhound dogs have significant physiologic, hematologic, and biochemical differences when compared with other breeds, including significantly lower serum globulin concentration owing to decreases in the α- and β-globulin fractions. The specific proteins that account for differences in globulin concentrations are not known, but IgA and IgM, both β-globulins, are potential candidates.

Objectives: The aims of this study were to measure serum IgG, IgA, and IgM in clinically healthy retired racing Greyhounds and compare the results with those of age- and sex-matched non-Greyhound dogs.
