In early animal development, cell proliferation and differentiation are tightly linked and coordinated. It is important, therefore, to know how the cell cycle is controlled during early development. Cdc25 phosphatases activate cyclin-dependent kinases (Cdks) and thereby promote cell-cycle
Alkaline phosphatases are ubiquitous enzymes involved in many important biological processes. Mammalian tissue-nonspecific alkaline phosphatase (TNAP) has long been thought to play an important role in bone mineralization. In this study, we identified a full-length cDNA encoding a potential alkaline
The aim of this study was to evaluate the association between juxtapapillary diverticulum (JD) and acute cholangitis (AC), and to analyze laboratory data to reveal the underlying mechanism. We conducted a retrospective review of 139 patients who underwent endoscopic retrograde
Periampullary duodenal diverticula are not uncommon and are usually asymptomatic although complications may occasionally occur. Here, we report the case of a 72-year-old woman who presented with painless obstructive jaundice. Laboratory tests showed abnormally elevated serum concentrations of total
History A 70-year-old man presented to the emergency department with fever, chills, rigors, and upper abdominal discomfort. Physical examination revealed jaundice and mild right upper quadrant tenderness. Laboratory tests revealed an increased C-reactive protein level of 133 mg/L (normal range,
Vertebrate glucose-6-phosphatase (G6Pase) consists of three isozymes: G6Pase-I, G6Pase-II and G6Pase-III. Despite extensive study on G6Pases in vertebrates, information regarding expression and regulation of G6Pase genes is rather limited in invertebrates. Here we report the identification of G6Pase
A line of hepatic endoderm cells, hepatoblast cell line 3 (HBC-3), was derived from the liver diverticulum of the mouse on day 9.5 of gestation by culture on a mitomycin C treated STON+ feeder layer in a hepatoblast culture medium consisting of Dulbecco's modified Eagle's medium, nonessential amino
OBJECTIVE
Although abdominal ultrasonography (US) is a good initial screening method for detection of biliary tract disease, we sometimes encounter patients who only have findings of dilatation of the common bile duct (CBD) on US, without specific biliary symptoms or jaundice. This study aimed to
The cricopharyngeal muscle (CPM) is essential for normal deglutition. Pharyngeal dysphagia commonly results from impaired or uncoordinated CPM dilation. Dysfunction of the CPM has also been implicated in the genesis of Zenker's (pharyngoesophageal) diverticulum. Despite the CPM's significance,
A case of a 52 year-old-male, with past medical history of renoureteral crisis and recurrent episodes of abdominal pain, is presented. The patient presented to the Emergency Department with abdominal pain (similar to previous episodes), fever and abnormal liver function test (marked elevation of
Primary sclerosing cholangitis (PSC) may have an atypical mode of presentation with recurrent cholangitis and diverticulum-like outpouchings of the hepatic ducts; a high clinical suspicion is required to confirm the diagnosis instead of ascribing cirrhosis to a secondary cause as a result of the
History A 68-year-old man was admitted to the hospital for work-up because of generalized fatigue, anorexia, chronic diarrhea, and weight loss. Laboratory work-up revealed an erythrocyte sedimentation rate of 58 mm/h (reference range, 3-23 mm/h), a hemoglobin level of 14.1 g/dL (reference range,
Differentiation of the endodermal cells of the mouse liver was studied enzymo- and immunocytochemically by analyzing the cellular localization of alphafoetoprotein (AFP), glycogen, and alkaline phosphatase (ALP) and 5'-nucleotidase (5'-Nase) activities. 1. In 8.5-day foetuses, AFP appears in some
Objective. Role of dysfunction of the sphincter of Oddi (SO) in choledocholithiasis is controversial. This study was to evaluate SO motor activity in patients with common bile duct (CBD) stones in the Han population of China. Patients and Methods. In this study, 76 patients with CBD stones were
Ninety-seven hepatolithiasis cases were reviewed retrospectively. Primary hepatolithiasis was about equal in both sexes, with most patients under 39 years of age. Most secondary hepatolithiasis patients who were female-predominant, were older than 40. Common presenting symptoms were abdominal pain,
