Enterovesical fistula is a relatively uncommon complication of colorectal and pelvic malignancies, diverticulitis, inflammatory bowel disease, radiotherapy, and trauma in Asian countries. A case of vesico-ileosigmoidal fistula and a literature review of this disease in Japan are presented. A 70-yr-old male was referred with complaints of urinary pain and(More)
The interactions of ergot alkaloids and of other drugs with dopamine (DA) and alpha-adrenergic receptors were investigated. The tested ergot alkaloids inhibit synaptosomal tyrosine hydroxylase activity and reverse the apomorphine-elicited inhibition of synaptosomal tyrosine hydroxylase activity. Thus, ergot alkaloids interact as both agonists and(More)
Recently, the caudate lobe has seemed to be the final target for aggressive cancer surgery of the liver. This lobe has five surfaces: the dorsal, left and hilar-free surfaces and the right and ventral-border planes. Surgeons have divided the caudate lobe into three parts: Spiegel's lobe, which is called the 'caudate lobe and papillary process' by(More)
Abstract The hilar bifurcation (HB), a wedged portion between the left and right portal vein origins, often issues the caudate branch. However, the HB territory in the caudate lobe has not been well recognized during liver surgery. In 50% of 48 human livers (25 usual livers and 23 with the external caudate notch), the HB gave off thick portal branches (> 1(More)
We reported previously a HLA-A24-restricted antigenic peptide, survivin-2B80-88 (AYACNTSTL), recognized by CD8(+) CTL. This peptide was derived from survivin protein, an inhibitor of apoptosis proteins, expressed in a variety of tumors, such as adenocarcinoma, squamous cell carcinoma, and malignant melanoma. In this report, we provide further evidence that(More)
AIM To determine whether superparamagnetic iron oxide-enhanced magnetic resonance imaging (SPIO-MRI) could replace intravenous contrast-enhanced spiral CT (iv-CT) and spiral CT during arterial portography (CTAP) combined with spiral CT hepatic angiography (CTHA) in the diagnosis of liver metastases from colorectal carcinomas. METHODS Twenty-six adult(More)
BACKGROUND/PURPOSE The present study was designed to anatomically assess a very recently reported hanging maneuver of the liver without mobilization, in which forceps are inserted blindly between the inferior vena cava (IVC) and liver parenchyma. METHODS We dissected 56 formalin-fixed livers (1) to determine whether preservation of the caudate vein (the(More)
The effect of fructose on the formation of advanced Maillard reaction products which show fluorescence and have crosslinking was investigated. Type I collagen was added to various concentrations of glucose and fructose which were then incubated at 37 degrees C for 4 weeks. The level of furosine and the fluorescence intensity both increased in direct(More)
Caspase-associated recruitment domains (CARD) are protein-protein interaction modules found extensively in proteins that play important roles in apoptosis. One of the CARD-containing proteins, TUCAN (CARD8), was reported previously as an antiapoptotic protein with a molecular weight of 48 kDa, which was up-regulated in colon cancer cells. We identified a(More)
Pancreas-sparing duodenectomy (PSD), which allows preservation of the pancreas in its entirety, is a promising procedure for low-grade malignancies of the duodenum, the periampullary region, and the neighboring retroperitoneum. We report a case of recurrent retroperitoneal liposarcoma involving the second and third parts of the duodenum, which was(More)
