BACKGROUND Combined hepatocellular and cholangiocarcinoma (CHC) is a unique subtype of liver cancer comprising both hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC); however, its cellular origin remains unclear. The purpose of this study was to investigate the clinicopathologic features and the clonal relationship between HCC and ICC in 34 patients with CHC. METHODS Th...
Malocclusion assessment methods are based on measurements of study casts, which requires that impressions be taken. In addition to being costly and time consuming, this process can be unpleasant for children. Therefore, the aim of this study was to evaluate intra- and inter-examiner reliability of intraoral score measurements to determine malocclusion severity in the permanent dentition. The re...
Intrahepatic cholangiocarcinoma (ICC) is a heterogeneous group of cancers of the intrahepatic biliary tract. However, few studies have evaluated integrin expression according to an ICC subgroup. We immunohistochemically investigated α6β4 (β4) and αvβ6 (β6) integrin expressions in 48 ICCs, and evaluated their relationship with clinical and pathological parameters and ligand expression, as well a...
BACKGROUND Although hepatitis C virus (HCV) infection is a possible pathogenetic factor for intrahepatic cholangiocarcinoma (ICC), clinicopathologic features of ICC patients with HCV infection remain unclear. PATIENTS AND METHODS Of 50 patients with ICC treated, 19 were infected with HCV (HCV-positive group) and 38 underwent surgical treatment. Clinicopathologic features and postoperative out...
Invasive cervical cancer (ICC) is common in areas where human immunodeficiency virus (HIV) is also prevalent. Currently, HIV seroprevalence as well as acceptability of HIV testing in ICC patients in Kenya is unknown. The objective of this study was to determine the acceptability of HIV testing among patients with ICC. Women with histologically verified ICC at Kenyatta National Hospital particip...
Ultrastructural characteristics of different subtypes of interstitial cells of Cajal (ICC) remain unclear in birds; however, birds have significant economical and scientific notability. Our aim was to describe and classify ICC in the chicken gut. The ileum of normal adult Three Yellow broiler chickens (n=10) were studied by transmission electron microscopy (TEM). The ICC were spindle- or stella...
The aim of this article is to provide a better understanding of the roles of interstitial cells of Cajal (ICC) in regulating gastrointestinal motility by reviewing in vitro and in vivo physiological motility studies. Based on the in vitro studies, ICC are proposed to have the following functions: to generate slow waves, to mediate neurotransmission between the enteric nerves and the gastrointes...
How nerves transmit their signals to regulate activity of smooth muscle is of fundamental importance to autonomic and enteric physiology, clinical medicine, and therapeutics. A traditional view of neurotransmission to smooth muscles has been that motor nerve varicosities release neurotransmitters that act on receptors on smooth muscles to cause their contraction or relaxation via electromechani...
Humoral hypercalcemia of malignancy (HHM) is caused by the oversecretion of parathyroid hormone-related peptide (PTHrP) from malignant tumors. Although any tumor may cause HHM, that induced by intrahepatic cholangiocarcinoma (ICC) or gastric cancer (GC) is rare. We report here a 74-year-old male who displayed HHM with both ICC and GC and showed an elevated serum PTHrP level. Treatment of the hy...
Interstitial cells of Cajal (ICC) generate the electrical slow wave required for normal gastrointestinal motility. The ionic conductances expressed in human intestinal ICC are unknown. The aim of this study was to determine expression of a Na+ current in human intestinal ICC and to determine the effects of the Na+ current on the slow wave. Visually identified, freshly dissociated, single ICC we...
