RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

Intracellular receptors that can be found in the cytoplasm or in the nucleus. They bind to extracellular signaling molecules that migrate through or are transported across the CELL MEMBRANE. Many members of this class of receptors occur in the cytoplasm and are transported to the CELL NUCLEUS upon ligand-binding where they signal via DNA-binding and transcription regulation. Also included in this category are receptors found on INTRACELLULAR MEMBRANES that act via mechanisms similar to CELL SURFACE RECEPTORS.

Effects of chronic nitric oxide activation or inhibition on early hepatic fibrosis in rats with bile duct ligation. (1/191)

Hepatic fibrosis or increased liver collagen contents drive functional abnormalities that, when extensive, may be life threatening. The purpose of this study was to assess the effects of the chronic stimulation or inhibition of nitric oxide synthesis in rats with hepatic fibrosis induced by permanent common bile duct ligation (3 weeks) and the role of expression of the different nitric oxide synthase isoforms. Bile duct ligation led to an important accumulation of collagen in the hepatic parenchyma, as shown both histologically and by the hydroxyproline contents of livers. Bilirubin and serum enzyme activities (measured as markers of cholestasis) increased several-fold after bile duct ligation. The area of fibrotic tissue, liver hydroxyproline content and serum markers of cholestasis were clearly related in obstructed rats. The absence of modifications in haemodynamic parameters excludes circulatory changes from being responsible for the development of liver alterations. In animals treated with NG-nitro-L-arginine methyl ester (L-NAME) the area of fibrosis was similar to that of untreated animals, the signs of cholestasis and cellular injury being more evident. In rats treated with L-arginine the area of fibrosis was almost three times larger than that found in bile duct ligated rats and in L-NAME-treated bile duct ligated rats, although the observed biochemical changes were similar to those seen in rats treated with L-NAME. Our results with inducible nitric oxide synthase, obtained by Western blots and immunohistochemistry, indicate a greater expression of the inducible enzyme in bile duct ligated and L-arginine-treated animals and a lower expression in the L-NAME and control groups. Constitutive nitric oxide synthase expression, obtained by Western blots, was very similar in all groups, except for the L-arginine-treated rats in which it was lower. These results suggest that nitric oxide production may be a key factor in the development of fibrosis in bile duct ligated rats. They also support the hypothesis of a dual role for nitric oxide; one beneficial, mediated by its circulatory effects, and the second negative, through its local toxic effects. (+info)

Carcinoids of the common bile duct: a case report and literature review. (2/191)

Carcinoids of the extrahepatic bile ducts and particularly the common bile duct are extremely rare. A 65-year-old woman presented with obstructive jaundice. Laboratory and imaging studies gave results that were consistent with an obstructing lesion in the common bile duct. In this case, a stent was inserted initially to decompress the bile ducts. Subsequently a laparotomy and pancreaticoduodenectomy were performed and a tissue diagnosis of carcinoid of the common bile duct was made. The patient was well with no evidence of recurrence 17 months postoperatively. The authors believe this is the 19th reported case of an extrahepatic bile duct carcinoid. (+info)

Biliary obstruction in hematopoietic cell transplant recipients: an uncommon diagnosis with specific causes. (3/191)

Jaundice is a common problem in marrow transplant recipients. The incidence of bile duct obstruction in this setting is unknown. The purpose of this study was to determine the incidence of biliary obstruction, the causes, and outcomes following marrow transplant. Consecutive cases were reviewed at two major transplant centers in the United States from 1969 to 1996 at the Fred Hutchinson Cancer Research Center and 1989 to 1996 at the City of Hope National Medical Center. Nine cases of biliary obstruction were identified as a cause of jaundice in 7412 marrow transplant recipients, an incidence of 0.12%. The presentation was bimodal, with seven cases occurring prior to day 100 and two occurring 2 to 4 years after transplantation. The age distribution was 15 to 50 years and all patients had received allogeneic transplants. The causes of obstruction included gallbladder sludge (n=1), a duodenal hematoma (n=1), choledocholithiasis with biliary pancreatitis (n=1), bile duct infection (n=2), recurrent malignancy (n=1), choledocholithiasis associated with a benign stricture (n=1), Epstein-Barr virus-related lymphoproliferative disorder (n=1), and a benign stricture of unknown etiology (n=1). Biliary obstruction is a rare cause of jaundice in the post-transplant period. The presentation was similar to that of other post-transplant hepatobiliary problems, but with disparate causes.

Biliary stenting versus bypass surgery for the palliation of malignant distal bile duct obstruction: a meta-analysis. (4/191)

The objective of this analysis is to compare endoscopic stenting with surgical bypass in patients with unresectable, malignant, distal common bile duct obstruction using the technique of meta-analysis. The inclusion criteria for the studies were randomized patient assignment, publication in the English language, 20 or more patients per group, all patients followed up until death, and follow-up and complications reported in an equivalent way for both treatment arms. Data extraction was performed independently by 2 of the authors. The number of treatment failures, serious complications, requirement for additional treatment sessions, and 30-day mortality were extracted. Three existing trials met the inclusion criteria, all of which compared surgery with the use of plastic stents. There were no studies identified that used metallic expandable stents. For the rate of treatment failure and serious complications, the odds ratios (ORs) of the 3 trials were heterogeneous, and no summary ORs were calculated. More treatment sessions were required after stent placement than after surgery, and a common OR was estimated to be 7.23 (95% confidence interval [CI], 3.73 to 13.98). Thirty-day mortality was not significantly different (OR = 0.522; 95% CI, 0.263 to 1.036). Although surgical bypass required fewer additional treatment sessions, existing data do not allow a definitive conclusion on which treatment is preferable. A larger randomized controlled trial using newer metallic stents and proper quality-of-life instruments is required. (+info)

Manometric changes during retrograde biliary infusion in mice. (5/191)

The manometric, ultrastructural, radiographic, and physiological consequences of retrograde biliary infusion were determined in normostatic and cholestatic mice. Intraluminal biliary pressure changed as a function of infusion volume, rate, and viscosity. Higher rates of constant infusion resulted in higher peak intraluminal biliary pressures. The pattern of pressure changes observed was consistent with biliary ductular and/or canalicular filling followed by leakage at a threshold pressure. Retrograde infusion with significant elevations in pressure led to paracellular leakage of lanthanum chloride, radiopaque dye, and [(14)C]sucrose with rapid systemic redistribution via sinusoidal and subsequent hepatic venous drainage. Chronic extrahepatic bile duct obstruction resulted in significantly smaller peak intrabiliary pressures and lower levels of paracellular leakage. These findings indicate that under both normostatic and cholestatic conditions elevated intrabiliary volumes/pressures result in an acute pressure-dependent physical opening of tight junctions, permitting the movement of infusate from the intrabiliary space into the subepithelial tissue compartment. Control of intraluminal pressure may potentially permit the selective delivery of macromolecules >18-20 A in diameter to specific histological compartments. (+info)

Extrahepatic biliary obstruction due to post-laparoscopic cholecystectomy biloma. (6/191)

BACKGROUND: Jaundice presenting after cholecystectomy may be the initial manifestation of a serious surgical misadventure and requires rigorous diagnostic pursuit and therapeutic intervention. Biloma is a well recognized postcholecystectomy complication that often accompanies biliary ductal injury. CASE REPORT: A 23-year-old female underwent laparoscopic cholecystectomy for symptomatic gallstones and three weeks postoperatively developed painless jaundice. Radiographic and endoscopic studies revealed a subhepatic biloma causing extrinsic compression and obstruction of the common hepatic duct. RESULTS: Percutaneous catheter drainage of the biloma combined with endoscopic sphincterotomy successfully relieved the extrahepatic biliary obstruction and resolved the intrahepatic ductal leak responsible for the biloma. CONCLUSION: Although heretofore undescribed, postcholecystectomy jaundice due to extrahepatic bile duct obstruction caused by biloma may occur and can be successfully treated by means of standard radiologic and endoscopic interventions.

Detection of Ki-ras gene point mutations in bile specimens for the differential diagnosis of malignant and benign biliary strictures. (7/191)

BACKGROUND AND AIM: The present study was undertaken to determine if detection of Ki-ras gene point mutations in bile specimens could differentiate between benign and malignant biliary strictures. PATIENTS: Bile specimens were obtained from 117 patients exhibiting a stricture of the main bile duct, the nature of which was assessed by cholangiography, histology, and follow up. METHODS: DNA from frozen bile specimens was extracted, amplified, and tested for codon 12 point mutations of Ki-ras gene using sequence specific oligonucleotide hybridisation and mutant allele specific amplification. RESULTS: DNA amplification was successful in 110/117 bile specimens (94%). Detection of Ki-ras gene mutations in bile specimens was positive in 24.4% (22/90) of patients with malignant strictures, in 31.4% (22/70) when only primary malignant tumours were considered, and in 4% (1/25) of patients with benign strictures. Of the 49 patients with histological specimens obtained before surgery, the sensitivity of histology, Ki-ras mutation analysis, and combined methods was 59.2%, 28.6%, and 73.5% respectively. CONCLUSIONS: Our study showed that Ki-ras mutations may be detected in about one third of bile specimens from patients with primary tumours invading the main bile duct. Detection of such mutations appears to be specific and may help to differentiate between benign and malignant biliary strictures. (+info)

Postoperative bile duct strictures: management and outcome in the 1990s. (8/191)

OBJECTIVE: To describe the management and outcome after surgical reconstruction of 156 patients with postoperative bile duct strictures managed in the 1990s. SUMMARY BACKGROUND DATA: The management of postoperative bile duct strictures and major bile duct injuries remains a challenge for even the most skilled biliary tract surgeon. The 1990s saw a dramatic increase in the incidence of bile duct strictures and injuries from the introduction and widespread use of laparoscopic cholecystectomy. Although the management of these injuries and short-term outcome have been reported, long-term follow-up is limited. METHODS: Data were collected prospectively on 156 patients treated at the Johns Hopkins Hospital with major bile duct injuries or postoperative bile duct strictures between January 1990 and December 1999. With the exception of bile duct injuries discovered and repaired during surgery, all patients underwent preoperative percutaneous transhepatic cholangiography and placement of transhepatic biliary catheters before surgical repair. Follow-up was conducted by medical record review or telephone interview during January 2000. RESULTS: Of the 156 patients undergoing surgical reconstruction, 142 had completed treatment with a mean follow-up of 57.5 months. Two patients died of reasons unrelated to biliary tract disease before the completion of treatment. Twelve patients (7.9%) had not completed treatment and still had biliary stents in place at the time of this report. Of patients who had completed treatment, 90. 8% were considered to have a successful outcome without the need for follow-up invasive, diagnos tic, or therapeutic interventional procedures. Patients with reconstruction after injury or stricture after laparoscopic cholecystectomy had a better overall outcome than patients whose postoperative stricture developed after other types of surgery. Presenting symptoms, number of stents, interval to referral, prior repair, and length of postoperative stenting were not significant predictors of outcome. Overall, a successful outcome, without the need for biliary stents, was obtained in 98% of patients, including those requiring a secondary procedure for recurrent stricture. CONCLUSIONS: Major bile duct injuries and postoperative bile duct strictures remain a considerable surgical challenge. Management with preoperative cholangiography to delineate the anatomy and placement of percutaneous biliary catheters, followed by surgical reconstruction with a Roux-en-Y hepaticojejunostomy, is associated with a successful outcome in up to 98% of patients.
