, novel etiological agent for traveler's diarrhea-report of four Japanese patients who returned from Southeast Asia and Papua New Guinea.

Background: Countries in the Southeast Asia region have a high prevalence of soil-transmitted helminth, such as roundworm, whipworm, and hookworms [, , ]. Recent molecular-based surveys have revealed that . , a zoonotic hookworm, is likely the second most prevalent hookworm species infecting humans in that part of the world, while others have noted that this infection is an emerging public health risk not only for indigenous people but also for visitors from other countries.

Uncommon lymphoepithelial cyst with sebaceous glands of the pancreas.

Context: Lymphoepithelial cysts with sebaceous glands of the pancreas are extremely rare, with only 7 cases, including this case, published in English literature.

Case Report: We herein present the case of a 67-year-old Asian man who underwent a resection of a lymphoepithelial cyst of the pancreas during the follow up care for lung cancer. Fourteen years previously he underwent a right lower lobectomy at the right segment nine for lung cancer.

[A case of hypervascular hyperplastic nodule in chronic alcoholic liver disease with corona-like enhancement in the late phase image of CT during hepatic arteriography].

A 46-year-old woman was admitted to our hospital with hepatic encephalopathy due to alcoholic liver disease. A hepatic nodule (20 mm in diameter) in S7 was enhanced in the early phase of contrast CT. No significant findings were observed in the late phase of contrast CT and SPIO MRI.

Bradykinin inhibits serum-depletion-induced apoptosis of human vascular endothelial cells by inducing nitric oxide via calcium ion kinetics.

Vascular endothelial cells play important roles in atherogenesis, and bradykinin is associated with atherosclerosis. The effect of bradykinin on apoptosis in human umbilical vein endothelial cells (HUVECs) was investigated, with a focus on Ca2+ kinetics and nitric oxide production. In serum-free conditions, the number of apoptotic cells increased in a time-dependent manner, but this increase was inhibited by bradykinin in a dose-dependent manner.
