13. Benign lymph node inclusions mimicking metastatic carcinoma.
AIMS--To draw attention to non-neoplastic inclusions in axillary lymph nodes removed from women with primary breast cancer which may be mistaken for metastases. METHODS--Five examples of non-malignant inclusions were detected in axillary lymph nodes removed from women with mammary carcinoma. Immunohistochemical staining for CAM 5.2 and S100 markers, as well

14. Systemic Antibodies Can Inhibit Mouse Mammary Tumor Virus-Driven Superantigen Response in Mucosa-Associated Lymphoid Tissues
Many mucosal pathogens invade the host by initially infecting the organized mucosa-associated lymphoid tissue (o-MALT) such as Peyer’s patches or nasal cavity-associated lymphoid tissue (NALT) before spreading systemically. There is no clear demonstration that serum antibodies can prevent infections in o-MALT. We have tested this possibility by using the m

15. Immune Response in the Bovine Mammary Gland After Intestinal, Local, and Systemic Immunization
The immune response in mammary glands of cattle was measured after intestinal, local, and systemic immunization with T4 bacteriophage. Nonlactating pregnant cows were immunized by infusions into the intestine or mammary gland and by subcutaneous injections in the region of the prescapular or external inguinal lymph nodes. Titers of antibodies of different is

16. Does a betaretrovirus infection trigger primary biliary cirrhosis?
Patients with primary biliary cirrhosis develop progressive ductopenia associated with the production of antimitochondrial antibodies that react with a protein aberrantly expressed on biliary epithelial cells and peri-hepatic lymph nodes. Although no specific microbe has been identified, it is thought that an infectious agent triggers this autoimmune liv

17. Fibrosarcoma affecting the mammary gland of a cow.
A highly malignant fibrosarcoma which arose in or close to the mammary gland of a 12 year old Ayrshire cow, with metastases in local lymph nodes, lungs, liver, kidney and adrenal glands has been described. The tumors were densely cellular and consisted of interweaving bands of fusiform cells with a high mitotic index. Infiltration of normal tissues and invas

18. A spectrum of monoclonal antibodies reactive with human mammary tumor cells.
Splenic lymphocytes of mice, immunized with membrane-enriched fractions of metastatic human mammary carcinoma tissues, were fused with the NS-1 non-immunoglobulin-secreting murine myeloma cell line. This resulted in the generation of hybridoma cultures secreting immunoglobulins reactive in solid-phase radioimmunoassays with extracts of metastatic mammary car

19. Bacterial persistence and immunity in goats vaccinated with a purE deletion mutant or the parental 16M strain of Brucella melitensis.
To evaluate host responses, young goats were inoculated subcutaneously with a genetic deletion mutant (deltapurE201) of Brucella melitensis (n = 6), its virulent parental strain 16M (n = 6), or saline (n = 6). No clinical evidence of brucellosis was seen in any goat. Serum antibody titers peaked at postinoculation day (PID) 14. Bacteria in lymph nodes that d

20. Glycosylation-dependent cell adhesion molecule 1 (GlyCAM 1) mucin is expressed by lactating mammary gland epithelial cells and is present in milk.
Glycosylation-dependent cell adhesion molecule 1 (GlyCAM 1) is a mucinlike endothelial glycoprotein that acts as an adhesive ligand for L selectin by presenting one or more O-linked carbohydrates to the lectin domain of this leukocyte cell surface selectin. The GlyCAM 1 glycoprotein has been previously shown to be expressed specifically by the endothelial ce

21. A highly sensitive in vitro infection assay to explore early stages of mouse mammary tumor virus infection.
Mouse mammary tumor virus (MMTV) infection of adult mice induces a strong response to superantigen (Sag) in their draining lymph nodes, which results from the presentation of Sag by MMTV-infected B cells to Sag-reactive T cells. To date, infection with physiologically relevant doses of MMTV can be detected in vivo only after several days of Sag-mediated T-ce

22. Conservation surgery after primary chemotherapy in large carcinomas of the breast.
OBJECTIVE: The authors evaluated the utility of preoperative chemotherapy in patients with large size breast carcinoma, with a view to rendering a conservative surgical approach possible or easier. SUMMARY BACKGROUND DATA: Two hundred twenty-six of 227 patients with breast cancer involving a tumor larger than 3 cm at greatest dimension were candidates for ma

23. Ectopic expression of A-myb in transgenic mice causes follicular hyperplasia and enhanced B lymphocyte proliferation
The A-myb gene is a transcription factor that shares structural and functional similarities with the v-myb oncogene. To date, v-myb is the only myb gene directly implicated in tumorigenesis, a property attributed to its transactivating ability. Recent studies have demonstrated that A-myb, like v-myb, is a potent transcriptional activator, raising the possibi

24. Outpatient biopsy of breast cancer. Influence on survival.
From 1948 to 1975, at the Istituto Nazionale Tumori of Milan, 209 patients underwent extended radical mastectomy (ERM) for breast cancer classified as T1 NO-1 MO. In 57 patients (27.3%), the ERM was preceded by an excisional biopsy performed in the outpatient clinic (Group A), of which 75% were performed within 30 days of admission and 25% after 30 days (ave
