Curcuma zedoaria is a characteristic species of its genus that contains little to no curcuminoid. Here, we demonstrate that C. zedoaria extracts with 50% methanol increases adiponectin secretion into the media by enhancing PPARγ mRNA expression in 3T3-L1 cells.

Mammary cancer is the most common type of cancer and the fifth most common cause of cancer-related deaths among Japanese women. The recent sharp increase in the number of women diagnosed with mammary cancer per year is thought to be associated with increased fat intake resulting from changes in the dietary habits of contemporary Japanese citizens. In this study, human c-Ha- proto-oncogene transgenic (Hras128) rats, which are highly susceptible to mammary carcinogens, were fed high- or low-fat diets to examine the relationship between fat consumption and the development of mammary cancer.

Angiosarcoma is a rare neoplasm, accounting for only 1%-2% of all sarcomas. It occurs most frequently in the skin and soft tissue and rarely in the thoracic region. To our knowledge, a mediastinal angiosarcoma is extremely rare.

Nectin-like molecule-5 (Necl-5) is an immunoglobulin (Ig)-like molecule that is up-regulated in many types of cancer cells. It was shown experimentally that Necl-5 enhances cell migration, proliferation, and metastasis, but its clinical significance has not been documented. The aim of this study was to observe the expression of Necl-5 in surgically resected primary lung adenocarcinomas and to investigate its clinical significance.

We report two postoperative cases of recurrent gastric carcinoma successfully treated with concurrent low-dose cisplatin/5-FU chemotherapy and radiation therapy. Case 1: A 74-year-old man underwent total gastrectomy and splenectomy for advanced gastric carcinoma followed by a local recurrence at the anastomotic site 6 months after surgery. Case 2: A 75-year-old man underwent total gastrectomy and splenectomy for advanced gastric carcinoma followed by multiple lymph node swelling along the abdominal aorta one year after surgery.

We report a case of a woman with a metastatic liver tumor from gastric carcinoma, who has been successfully treated with concurrent proton beam therapy and systemic chemotherapy. A 76-year-old woman underwent distal gastrectomy with regional lymph node dissection for advanced gastric carcinoma on January 17, 2002. She received five courses of sequential chemotherapy with methotrexate-5-fluorouracil after the surgical resection.

The extractability of hordeins from barley grains was investigated after wet and dry heating conditions. It was found that the amount of hordeins extractable with 55% 2-propanol decreased in a time-dependent manner after barley grains were steamed (wet heating), whereas hordeins showed no effect from heating in an oven at 100 degress C for up to 120 min (dry heating). The result of SDS-PAGE analysis revealed that B-hordein decreased time-dependently in extractability with wet heating and had almost completely disappeared by 60 min, but C-hordein remained unchanged until 120 min.
