a case of pleomorphic adenoma in sweat gland is reported here. the histopathologic report confirmed the diagnosis. pleomorphic adenoma is most common in salivary glands but very rare in sweat glands. pleomorphic adenoma in sweat gland and the similar tumors of eccring sweat gland are described that bear a striking resemblance to pleomorphic adenomas of salivary gland. upon closer examination, t...

absract a case of 69- year-old woman with large pelvic mass and ascites is reported in this paper. with the exception of mild pelvic pain and a pelvic mass in pelvic , she had no symptom or sign . all routine and hormonal lab tests and tumor marker's were normal. the mri revealed a large mass in anterosuperior of uterus, and left ovary was situated in neighborhood of pelvic mass.her uterus norm...

Resistant starch is as common soluble fiber that escapes digestion in the small intestine and can regulate intestinal function, metabolism of blood glucose and lipids, and may prevent tumorigenesis of gastrointestinal cancer. Epidemiology and other evidence have suggested that resistant starch may prevent colon cancer development. The aim of the current study was to explore the ameliorative eff...

A 58-year-old man was revealed to have multiple liver tumors with elevated prostatic acid phosphatase (PAP) during a medical examination. The tumors were of neuroendocrine nature, but no abnormal findings were obtained in other organs in which neuroendocrine tumors develop frequently. Repeated transarterial embolization was partially effective. However, the tumors became resistant to the therap...

BACKGROUND Ovarian cancer is one of the most lethal types of female malignancy. Although most patients are initially responsive to platinum-based chemotherapy, almost all develop recurrent chemoresistant tumors and succumb to their diseases. Elucidating the pathogenesis underlying drug resistance is fundamental to the development of new therapeutics, leading to improved clinical outcomes in the...

Levels of mRNA expressed by the multidrug resistance gene MDR1 were examined in 23 renal cell carcinoma samples and adjacent normal kidney cortex using reverse-transcription PCR. Comparison of MDR1 levels between histological types revealed that there was on average significantly more MDR1 in clear cell tumors than in oncocytomas (0. 89 +/- 0.10 versus 0.28 +/- 0.20, ratio of MDR1 in tumor cell...

Elastin-like polypeptides (ELPs) undergo a characteristic phase transition in response to ambient temperature. Therefore, it has been be used as thermosensitive vector for the delivery of chemotherapy agents since can target hyperthermic tumors. This novel strategy introduces unprecedented options treating cancer with fewer concerns about side effects. In this study, ELP system was further modi...

Replication-restricted herpes simplex virus-1 (HSV-1) strains lacking ICP34.5 are emerging as powerful anticancer agents against several solid tumors including epithelial ovarian cancer (EOC). Although chemotherapy-resistant tumors would be likely candidates for treatment with HSV-1 mutants lacking ICP34.5, the efficacy of these mutants on such tumors is unknown. In the present study, we invest...

Comparison is made of the development of resistance to cyclophosphamide (CPA) and L-phenylalanine mustard (L-PAM), of cross-resistance, and chromosome counts, in Walker 256 (W256), rat sarcoma R3 (R3), leukemia L1210, and Ridgway osteogenic sarcoma. For development of resistance the single maximum tolerated doses of CPA or L-PAM were used, each for two sublines in the four tumors. In W256 after...
