Histological analysis of 70-nm silica particles-induced chronic toxicity in mice

Brain MRI was carried out in patients with chronic liver diseases. No abnormal findings were recognized in patients with chronic viral hepatitis, while 59.2% of cirrhotics showed a symmetrically strong signal in basal ganglia on T1 weighted image in MRI. This finding significantly related with lowered Fischer`s ratio of serum amino acid, increased levels of serum phenylalanine, tyrosine and hyaluronic acid, prolonged prothrombin time and decreased platelet counts in the peripheral blood. Overt hepatic encephalopathy was observed in 6 of 34 patients with the strong signal in MRI during follow-up period, while none of patients without that finding developed hepatic encephalopathy. These results have indicated that the strong signal in basal ganglia on MRI appears in cirrhotic patients with severe liver dysfunction, and it is an useful index in the early diagnosis of latent ...

Nano-sized silica is a promising material for disease diagnosis, cosmetics and drugs. For the successful application of nano-sized material in bioscience, evaluation of nano-sized material toxicity is important. We previously found that nano-sized silica particles with a diameter of 70nm showed acute liver failure in mice. Here, we performed histological analysis of major organs such as the liver, spleen, lung, kidney, brain and heart in mice, chronically injected with 70-nm silica particles for 4weeks. Histological analysis revealed hepatic microgranulation and splenic megakaryocyte accumulation in these 70-nm silica particles treated mice, while the kidney, lung, brain and heart remained unaffected. Thus, liver and spleen appear to be the major target organs for toxicity by the chronic a...

Hepatocellular Carcinoma (HCC)

Biomarkers of fibrosis and impaired liver function in chronic hepatitis C: how well do they predict clinical outcomes?

Hepatocellular carcinoma (HCC) is considered to be one of the most common malignancies worldwide, and the most common one in Africa and Asia. Over the last decade, a rising incidence of up to 10-15/100,000 per population has been seen in the Western world, with an estimate of 250,000 deaths and more than a million worldwide per year. By the year 2010, the World Health Organization expects that HCC will be the leading cause of cancer mortality surpassing lung cancer. This increasing incidence is most likely related to an increasing prevalence of chronic hepatitis C (HC) and B (HB) virus infections and other diseases inducing chronic inflammation (Befeler and Di Bisceglie 2002; Llovet et al. 2003).

PURPOSE OF REVIEW: To review the recent literature on the prognostic value of biomarkers of liver fibrosis and impaired liver function in patients with chronic hepatitis C with or without HIV coinfection. RECENT FINDINGS: A combination of standard blood tests seems to be useful in identifying patients at risk of liver-related complications. Findings from studies investigating the validity of the Model for End-Stage Liver Disease (MELD) score in HIV-infected liver transplant candidates are conflicting. Two large studies of HIV/hepatitis C virus (HCV) coinfected patients have shown that plasma levels of the fibrosis marker hyaluronic acid are a strong predictor of clinical complications. A smaller study found hyaluronic acid and two other fibrosis tests, aspartate aminotransferase-to-platelet ratio index (APRI) and Fib-4, to be independent predictors of mortality when included in models with the MELD or the ...

Current status of a hepatitis C vaccine: encouraging results but significant challenges ahead

PMID:21877636

2011-08-01

DEFF Research Database (Denmark)

Persistent hepatitis C virus (HCV) infection affects 170 million people worldwide. Acute HCV infection is often asymptomatic, but many infected individuals develop persistent infections that may lead to development of end-stage liver diseases, including liver cirrhosis and hepatocellular carcinoma. Thus, an HCV vaccine that could significantly lower the chronicity rate would have a major impact on the disease burden. Unfortunately, HCV is a highly mutable virus, and escape mutations can undermine vaccine-induced virus-specific immunity. Also, HCV exists as multiple genotypes, and so genotype-specific vaccines might be required to achieve broad protection. Finally, vaccine development has been hampered by the lack of a small animal model and cell culture systems, but these are currently being established. Despite these obstacles, several vaccine candidates tested in the chimpanzee HCV model have shown some encouraging results.

An immunohistochemical study in cases with usual and unusual clinicopathological findings of canine visceral leishmaniosis

British Library Electronic Table of Contents (United Kingdom)

The present study describes pathologic findings and immunohistochemical diagnosis of canine visceral leishmaniasis (CVL) in 22 dogs who died naturally in the Aegean region of Turkey. At necropsy, lymphadenomegaly, hepatosplenomegaly, hepatic, and nephrosclerotic lesions were conspicuous. Histopathologically, chronic inflammatory reactions of the spleen, lymph nodes, bone marrow, liver, and skin were marked findings. Cytological and histological examinations showed macrophages loaded with Leishmania amastigotes in these organs. Immunohistochemistry revealed that immunolabeling of amastigotes and/or parasite antigen, especially in the lymph nodes, spleen, bone marrow, liver, and skin, and occasionally, in the kidneys, intestines and lungs. Our laboratory results showed that immunohistochemis...

Temporal trends in hepatitis B and C infection in family blood donors from interior Sindh, Pakistan

Cholangiocarcinoma is synonymous with bile duct carcinoma, and can originate in a small intrahepatic bile duct (peripheral type), a major intrahepatic duct including the hepatic hills, an extrahepatic duct, or near the papilla of Vater (central type). In a sense bile duct carcinoma of the peripheral type is cholangiocarcinoma of the liver; it has the same gross configuration as hepatocellular carcinoma, resulting in difficulty to differentiate on the CT. The authors studied CT findings of 14 cases of pathologically proven peripheral type cholangiocarcinoma of the liver during the last 4 years. The results were as follows: 1. Of 14 cases, 8 were female and 6 were male, and the age ranged from 5th to 7th decades. 2. Preoperative clinical diagnosis were as follows: hepatoma 8 cases, abscess 5 cases and metastasis 1 case in order of frequency. 3. Diagnosis were confirmed by hepatic lobectomy in 7 cases, wedge resection in 5 cases and needle biopsy ...

The Influence of Abacavir and Other Antiretroviral Agents on Virologic Response to Hepatitis C Virus Therapy Among Antiretroviral-Treated HIV-Infected Patients

The disruption of primary innate immune function of the epidermal layer of the skin accounts for the susceptibility of individuals using bleaching agents to localized or systemic infections. This subverted innate immunity in these people may lead to other pathological conditions. The resultant effects of skin bleaching and phagocytes activation in response to infections have not been studied in Nigerians using bleaching agents. The present study therefore assessed the levels of C-reactive protein (CRP), albumin, total antioxidant potential (TAP), total plasma peroxides (TPP), oxidative stress index (OSI) and malonaldehyde (MDA) in the users bleaching agents. Thirty (30) people who had used bleaching agents for average of 4.9 + 1.2 years participated in this study. They were recruited from various schools and markets within the city of Ibadan, Oyo State, Nigeria. Thirty apparently healthy staffs of University College Hospital Ibadan, Ibaadan, Nigeria, who had never used bleaching agents ...

Radiation exposure to patients during hepatic interventional procedure

Assessment of liver circulation by quantitative scintiangiography: Evaluation of the relative contribution of the hepatic arterial and portal venous blood flows to liver perfusion

Objective: To investigate the X-ray radiation dose patients dealt with the hepatic intervention. Methods: Thermoluminescence and tissue-equivalent anthropomorphic phantom were used to measure the X-ray radiation dose in patients dealt with the hepatic intervention in 85 patients. Results: The peak skin dose in the patients who accepted hepatic intervention was from 179.95 to 1759.00 mGy, effective dose approached 29.22 mSv (male), 29.27 mSv (female). Conclusion: Hepatic intervention is now regarded as an important therapeutic method for liver cancer. However, the patients were exposed to too much X-ray radiation during interventional procedures. Some more effective protection should be taken to decrease the X-ray radiation dose accepted by patients. (authors)

The hepatic-arterial/portal-venous scintiangiogram in alcoholic hepatitis

This study was designed to identify abnormalities in the hepatic-arterial/portal-venous scintiangiogram (SA) in alcoholic hepatitis (AH). SA's were performed in 35 patients with acute alcoholic hepatitis (AAH), 8; acute alcoholic hepatitis superimposed on cirrhosis (A/C), 14; and cirrhosis (C), 13. Posterior flows were done with a bolus of 10 mCi Tc-99m sulfur colloid with computer time-activity curves over the liver and left kidney. Curves were analyzed for per cent of hepatic arterial (HA) and portal venous contribution using the slope ratio method. Hepatic arterialization was estimated from the angle of the HA component of the curve. Reversal of the relative contribution of the hepatic and portal components of total flow were seen in all groups. Although quite severe in AH, the degree of reversal could not be used to ...

Diagnostic value of MRI for hepatic hilar cholangiocarcinoma

Chronic benign pain is commonly associated with chronic fatigue and depression. Depression and chronic fatigue syndrome are also associated with each other and often include pain. Psychologic factors are prominent in these conditions, and they may share neurobiologic factors as well. Management requires separately addressing each component of patients' distress and usually includes physical rehabilitation, education, administration of nonhabituating medications and often counseling. Depression may be a favorable prognostic sign, as it suggests a treatable condition and provides incentive for recovery. PMID:1876618

Symptomatic hepatic cyst in a child: treatment with single-shot injection of tetracycline hydrochloride

Objective: To investigate the value of MRI in the diagnosis of hepatic hilar cholangiocarcinoma. Methods: Sixty-four patients with hepatic hilar cholangiocarcinomas confirmed by surgery or pathology underwent MRI using a 1.5-T superconductive MR system including conventional unenhanced MRI, MRCP and dynamic contrast-enhanced MRI with Gd-DTPA. Results: Dilatation of the intrahepatic biliary tree with narrowing, occlusion or filling defects in the hepatic hilar bile ducts was noted in all 64 cases. Unenhanced MR[ showed T_1- and T_2-hyperintense hilar masses in 42 patients and was normal in the remaining 22 patients. The hilar masses demonstrated slow, progressive and delayed enhancement patterns. There was enhancement of the thickened bile duct wall with luminal narrowing in the 22 patients without hilar masses. Conclusion: The characteristic MRI findings of enhancing hepatic hilar mass and bile duct ...

Changing Treatment Paradigms Hepatitis C Virus in HIV-Infected Patients

The prevalence of hepatic cysts is 0.1% to 0.5% based on autopsy studies, and 2.5% based on US examinations. Percutaneous therapies are a new alternative to surgery. They include simple percutaneous aspiration, catheter drainage alone, and catheter drainage with sclerotherapy. We present an 11-year-old boy admitted to hospital because of abdominal pain. A diagnosis of simple hepatic cyst was made, which was treated with aspiration and tetracycline hydrochloride solution (5%) injection into the cystic cavity. Complete regression was seen on US and MRI examination at 3 months, with total collapse and deflation of the cyst. The cyst regressed totally, leaving a hyperechoic linear scar on US examination at 1 year. On the basis of the clinical and imaging results obtained, percutaneous sclerotherapy of hepatic cysts can be recommended as the treatment of choice and as a valid alternative to laparoscopy in children.

The evaluation of hepatic histology and treatment of hepatitis C virus (HCV)/HIV-coinfected patients is rapidly changing. HCV has become an important cause of mortality in HIV-infected patients. Consequently, assessment of liver histology in all coinfected patients is particularly important. The evaluation of hepatic histology is shifting from reliance on the liver biopsy toward noninvasive modalities. Additionally, the importance of HCV-associated morbidity and mortality in HIV-infected patients has prompted increasing numbers of these patients to be HCV treatment candidates. Prospective trials in coinfected patients have reported lower sustained virologic responses compared to HCV-monoinfected patients. Consequently, the numbers of coinfected nonresponders to pegylated interferon/ribavir...

Comparison of the effects of enteral feeding with continuous and intermittent parenteral nutrition on hepatic triglyceride secretion in human beings

Xenotropic murine leukaemia virus-related virus (XMRV) does not cause chronic fatigue.

Plasma triglyceride turnover was measured during steady-state conditions in 22 postoperative patients. Nine had received nutritional support with an enteral regimen, seven had received an equivalent regimen as continuous parenteral nutrition, and six received the same parenteral regimen as a cyclical infusion. After 5 days of nutritional support, each patient received an intravenous bolus of tritiated glycerol. Plasma radiolabeled triglyceride content was measured during the subsequent 24 hours. The data were analyzed by means of a simple deterministic model of plasma triglyceride kinetics and compared with the results obtained by stochastic analysis. The rates of hepatic triglyceride secretion obtained by deterministic analysis were higher than those obtained by the stochastic approach. However, the mode of delivery of the nutritional regimen did not affect the rate of hepatic triglyceride secretion regardless of the method of analysis. The ...

It was subsequently detected in chronic fatigue patients in 2009. The association between XMRV and chronic fatigue has proved to be controversial. No study has confirmed these findings and many have refuted them. Here, we present the evidence for our contention that XMRV is not a human pathogen. PMID:21978843

Abstract An increase in chronic disease prevalence is contributing to health care cost growth and decreased quality of life in industrialized nations worldwide. Inadequate management of chronic diseases is a leading cause of hospitalizations and, thus, avoidable expenditures. In this study, we evaluated the impact of nurse-delivered care calls, the primary intervention of a proactive chronic care management (CCM) program, in a population aged 65 and older in Germany. In this analysis, hospital admission rates were evaluated among program enrollees who were diagnosed with diabetes, heart failure, coronary heart disease, or chronic obstructive pulmonary disease. The Intervention group comprised those members who participated in care calls (n?=?13,486), whereas the Comparison group included e...

Physical therapy for chronic pain conditions—A novel approach using mind–body connection

British Library Electronic Table of Contents (United Kingdom)

The treatment of chronic pain conditions continue to present a challenge to the medical field. Physical therapy treatment needs to approach the management of chronic pain differently than the approach used to resolve acute pain. Patients with chronic pain often have many factors that have perpetuated the pain condition. These factors, as well as pain itself, influence their ability to reactivate and perform functional daily activities. Physical therapists can begin to address some of the factors, including fear and deconditioning, by building confidence and body awareness in a self-care model including a slow graduated reactivation program. There is evidence that patients with chronic pain conditions have altered motor control that may be influencing reoccurrences and possible flares of pa...

Weak Association between SEN Virus Viremia and Liver Disease

Intra-arterial subtraction angiography(IADSA) using Fuji computed radiography(FCR) was performed on 130 patients with cervical, pelvic, peripheral and abdominal diseases. It was compared with conventional angiography(radiographs produced by combining photographic film with an intensifying screen) performed on same patients. Radiographs produced by FCR were better than conventional radiographs in cervical, pelvic and peripheral angiography. In the abdominal angiography using FCR, there was misregistration artifact in some cases, but in hepatic angiography, the new radiographs under the injection of small amount of contrast medium(about 10ml) and the short exposure duration(about 10 seconds) were excellent. It was as valuable as conventional angiography (infusion hepatic angiography) for diagnosing hepatic neoplasms. (author).

Abstract Background & aims: Hepatitis B or C virus infection is considered to be the main cause of hepatocellular carcinoma (HCC) in Japan. Aflatoxin B1 (AFB1) is a carcinogen associated with HCC in regions with high exposure. Mutations in codon 249, exon 7 are a hallmark of AFB1 exposure. Therefore, to clarify the role of AFB1 in hepatocarcinogenesis, we examined AFB1-DNA in liver tissue and sequenced TP53 in Japanese patients with HCC. Methods: Hepatocyte AFB1-DNA adducts were determined immunohistochemically and direct sequencing of TP53 was done to determine mutations in 188 of 279 patients who underwent hepatic resection for HCC. We assessed hepatitis C virus antibodies (HCV Ab) and HBSAg expression; patients without either were defined as having non-B non-C hepatocellular carcinoma (...

Tetracycline hydrochloride sclerotherapy; renal, hepatic, ovarian, and perivesical cysts

Dilatation of the azygos vein is usually due to increased pressure or flow, rarely is it diopathic. Another cause is so-called continuation of the azygos in cases of absence of the hepatic segment of the inferior vena cava. The method of choice for the investigation of azygos dilatation nowadays is computer tomotgraphy. Anomalies of the inferior vena cava can be recognised in this way unequivocally by a non-invasive method. Computer tomography frequently shows important additional abnormalities (e.g. situs inversus, polysplenia), since it demonstrates all organs situated in the plane of section. (orig.).

Comparison between children and adolescents with and without chronic benign pain: consultation rate and pain characteristics.

To assess the efficacy and resulting complications of tetracycline sclerotherapy in renal, hepatic, ovarian, and perivesical cysts. We retrospectively reviewed 23 cases of benign cysts (16 renal, 4 hepatic, 2 ovarian, and 1 perivesical) in 22 patients in whom the condition was diagnosed or confirmed by either ultrasound, CT, or cytology, and who underwent percutaneous tetracycline sclerotherapy. Using a 21-gauge Chiba needle, the target cyst was punctured under ultrasound guidance. Prior to the injection of 1500 mg of tetracycline diluted in 5 ml of normal saline, almost all the cystic content was aspirated, and at the end of the procedure the tetracycline was left in the cyst. During a period of between 3 and 22 months, 18 of the 23 cases were followed up. In six of the 18 cases followed up, the cysts either decreased in size by 10%, or collapsed completely. In seven cases a collapse of over 50% was noted, and in the remaining five the cyst ...

The role of lesions of DNA in senescence of seeds of Lupinus polyphyllus L. induced by chronic low-intensity irradiation

The aim of the study was to determine whether children with chronic benign pain are in contact with their general practitioner (GP) more frequently than those without chronic benign pain. A random sample of children and adolescents aged between 0 and 18 years of age was drawn from the records of ten general practices. According to their responses to a pain questionnaire, subjects were assigned to the chronic benign pain group (n = 95) if they had pain of more than three months' duration, or to the control group (n = 105) if they had pain of less than three months' duration or no pain at all. All the subjects had an average GP consultation rate of 2.6 contacts per year. No significant age and sex differences were found. Chronic benign pain in childhood and adolescence is not related to increased use of healthcare services, suggesting that somatisation does not play a major role in children with ...

The behavioral management of pain: a criticism of a response.

A nonlinear relationship between the time of accelerated aging of Lupine seeds and the indices of its survival as well as the single-strand DNA amount in cells from these seeds is established. The character of this relationship is essentially altered in chronically irradiated lupine seeds from the Chernobyl NPP exclusion zone and seems more complicated. The possible role of repair systems in these effects is discussed. The fact that chronic irradiation in low doses can modify the course of senescence in lupine seeds reflects its high biological efficiency comparing with acute irradiation.

[Changes in the mucous membrane of the esophagus and stomach in patients with chronic alcoholism during the period of acute alcoholic intoxication (according to fiber endoscopy and spot biopsy data)].

In response to an earlier published paper by Fordyce, some assumptions underlying the behavior management paradigm of chronic pain are critically discussed. While operant treatment has proved successful, the conclusion that operant factors play an important role in the development and maintenance of chronic benign pain is debated. Some empirical studies, regularly used to demonstrate this role, are re-evaluated. An alternative theory is proposed for chronic pain behavior, in which the role of a lower tolerance to proprioceptive stimuli, which may include more than just pain stimuli, is emphasized.

Dietary Phosphorus Acutely Impairs Endothelial Function

Lupinus albus L. plants were grown from seeds and irradiated at various stages of development with acute or chronic gamma rays. All plants were greenhouse grown (pre- and post-irradiation) and allowed to proceed through their normal growth cycle. The purpose of these experiments was to establish a Plactochron Index for Lupinus albus L. and to determine the effects of acute and chronic irradiation on development at the macro and microscopic levels. A Plastochron Index was calculated and used as an indirect time scale to evaluate the effects of gamma rays from a common base line. Acute radiation treatment lasted for a period of a few days, whereas chronic treatment was initiated at the seedling stage and lasted for the entire growth season. Vegetative plants were used to study the effects of acute radiation exposure on apical meristem morphology, Plastochron Index, phyllatoxis and gross morphology.

Hepatic abscess versus peripheral cholangiocarcinoma: Sonographic differentiation

The imaging findings of small({<=}15mm) portal defects in the liver on CT arterial portography : evaluation with CT hepatic arteriography and lipiodol CT

To find out the sonographic findings that are useful to differentiate hepatic abscess from peripheral cholangiocarcinoma. Twenty-two hepatic abscesses and 22 peripheral cholangiocarcinomas which had been confirmed histologically were included in this study. Objective points were echo characteristics of the lesion, internal septation, presence of peripheral low echoic rim, demarcation from normal liver(well or poorly defined), posterior enhancement, multiplicity, dilatation of bile duct(obstructive or non-obstructive), intrahepatic duct stone, pleural effusion, and intra-abdominal fluid collection. Echo characteristics of the lesion were classified in-to four types. Type I; Predominantly echogenic with hypoechoic portion, type II; Echogenic without hypoechoic portion, type III; Predominantly hypoechoic with echogenic portion, type IV; Hypoechoic without echogenic portion. 1)Nine abscesses and 2 peripheral cholangiocarcinomas were type ...

Hepatitis B immunization coverage and risk behaviour among Danish travellers Are immunization strategies based on single journey itineraries rational?

To assess the malignant potential of small({<=}15mm) portal defects seen on CT arterial portography, the findings of CT hepatic arteriography and lipiodol CT were reviewed. In 91 patients who underwent both CTAP and CTHA, small portal defects were reviewed for frequency, multiplicity and location. We prospectively evauluated changes in the size and enhancement pattern of malignant lesions on follow up CT according to density on CTHA, location, lipiodol deposits on lipiodol CT, and multiplicity. Among the 91 patients, 102 small defects were defected in 42 patients(46%). Small portal defects were benign, malignant, and of undetermined malignant potential in 77%, 20% and 3% of cases, respectively. Small portal defects that were hyperattenuated on CTHA, and lipiodol deposits on lipiodol CT, were malignant in 42% and 70% of cases, respectively. Location and multiplicity did not show statistically significant variation between benign and malignant defects. Small ...

OBJECTIVES: The authors examine the rationale and efficacy of pre-travel hepatitis B immunization strategies based on itinerary and presumed on-travel risk behaviour. METHODS: A large survey among 26,640 Danes survey provided data on journey lengths and destinations, immunization coverage, risk behaviour and knowledge. RESULTS: The estimated cumulative lifetime stay in endemic areas outside Europe is 4.3 months. The majority of risk situations are involuntary and unforeseeable. The majority of risk situations occur on short-term journeys. 5% nonimmune and 5% short-term travellers experienced at least one risk situation such as injections/operations/tattoos on their journey. The level of knowledge of hepatitis A and B is low. CONCLUSIONS: The rationale and efficacy of current immunization strategies are challenged. Based on the results presented here and the availability of vaccines with long-lasting coverage, the authors find that ...

Analysis of the placement of multiple metallic stents in the treatment of hilar cholangiocarcinoma

Alteration of the enterohepatic recirculation of bile acids in rats after exposure to ionizing radiation

Objective: To evaluate the clinical efficacy of multiple stents placement in the management of hilar cholangiocarcinoma, especially in the complex cases of which the hepatic ducts are invaded. Methods: Forty-five consecutive patients with hilar cholangiocarcinoma were treated with percutaneous transhepatic placement of two or three self-expandable metallic endoprostheses. The cause of hilar obstructions in these patients were all cholangiocarcinoma, including Bismuth classification type II (n 12), IIIa (n 17), IIIb (n 10), and IV (n 6). Two or 3 stents were placed in the configuration of T, Y or X over the strictures. Results: Stent placement with 2 or 3 endoprostheses was successful in all patients. All patients showed significant decrease in serum bilirubin level. The mortality rate within 30 days of stent placement was 2.2% (1/45). The mean survival and stent patency times were 215.3 d (26- 516 d) and 181.5 d (26-473 d), respectively. Conclusion: Deploying of ...

Treatment of hilar cholangiocarcinoma with inserting biliary double stents

The aim of this work was to study acute alterations of the enterohepatic recirculation (EHR) of bile acids 3 days after an 8-Gy radiation exposure in vivo in the rat by a washout technique. Using this technique in association with HPLC analysis, the EHR of the major individual bile acids was determined in control and irradiated animals. Ex vivo ileal taurocholate absorption was also studied in Ussing chambers. Major hepatic enzyme activities involved in bile acid synthesis were also measured. Measurements of bile acid intestinal content and intestinal absorption efficiency calculation from washout showed reduced intestinal absorption with significant differences from one bile acid to another: absorption of taurocholate and tauromuricholate was decreased, whereas absorption of the more hydrophobic taurochenodeoxycholate was increased, suggesting that intestinal passive diffusion was enhanced, whereas ileal active transport might be reduced.

The antiviral action of common household disinfectants and antiseptics against murine hepatitis virus, a potential surrogate for SARS coronavirus

Objective: To investigate the inserting technique of biliary double stents in treating hilar cholangiocarcinoma. Methods: 6 patients with hilar cholangiocarcinoma (Bismuth IV) were treated by percutaneous transhepatic insertion of biliary stents. Double stents were inserted in each patient. Different inserting methods were adopted according to the branch angles formed by left and right hepatic ducts. Results: The jaundice of all patients alleviated or disappeared obviously after stent implantation. The average difference between post-and pre-operation in the serum total bilirubin level was (104 #+-# 29) #mu#mol/L (P<0.01). Stent obstruction was found in 2 cases after 4 and 6 months respectively. Conclusion: Double stents implantation is effective for the treatment of hilar cholangiocarcinoma. Beware of the angulation between main hepatic duct and adopting different inserting methods. (authors)

Steatohepatite non alcoolique chez une adolescente obese : une biopsie hepatique discutable

British Library Electronic Table of Contents (United Kingdom)

The growing epidemic of juvenile obesity has prompted pediatricians to investigate obesity-related conditions in obese teenagers. We report a clinical case of severe hepatic fibrosis in an adolescent with severe and recent obesity. Because of elevated serum aminotransferase levels, abnormal hepatic ultrasonography and insulin resistance (impaired glucose tolerance), we suspected nonalcoholic steatohepatitis (NASH). Disease activity and fibrosis were confirmed on liver biopsy. Considering the risk of progression toward cirrhosis and its complications, and the pathological liver lesions, we started long-term medical monitoring and drug therapy to control weight loss. At present, although biopsy is the only validated way to establish the diagnosis of NASH, there is no consensus on its indicat...

Selenium Accumulation in Sea Ducks Wintering at Lake Ontario

British Library Electronic Table of Contents (United Kingdom)

Numbers of wintering sea ducks, including buffleheads (Bucephala albeola; BUFF), common goldeneyes (Bucephala clangula; COGO), and long-tailed ducks (Clangula hyemalis; LTDU), increased substantially at Lake Ontario after Dreissenid mussels (Dreissena bugensis and D. polymorpha) colonized the Great Lakes. Invertebrates, including Dreissenid mussels, are major diving duck prey items that can transfer some trace elements, such as selenium (Se) to higher trophic levels. Se can be problematic for waterfowl and it often has been detected at elevated levels in organisms using the Great Lakes. There are, however, few data on hepatic Se concentrations in sea ducks, particularly during the winter at Lake Ontario.

Hepatitis C virus core upregulates the methylation status of the RASSF1A promoter through regulation of SMYD3 in hilar cholangiocarcinoma cells

British Library Electronic Table of Contents (United Kingdom)

Increasing evidence has been accumulated indicating the important role of epigenetic regulation in tumor genesis. Previously, we observed that the transfection of hepatitis C virus core (HCVc) protein led to malignant transformation in normal biliary cells, and that tumor suppressor gene RASSF1A was downregulated in many hilar cholangiocarcinoma patients by hypermethylation in the promoter region. In the present study, we found SET and MYND domain-containing protein 3 (SMYD3), a novel histone methyltransferase, was overexpressed in cholangiocarcinoma patients especially in those with HCV infection. Transfection of HCVc into hilar cholangiocarcinoma cell lines QBC939 and FRH0201 could upregulate the expression of SMYD3 and promote cell growth, which was consistent with the results of our cl...

British Library Electronic Table of Contents (United Kingdom)

Abstract Hepatitis B (HBV) and C (HCV) viruses are the most important infections transmitted by the parenteral route in patients receiving maintenance dialysis. The prevalence varies markedly from country to country. The aim of this study is to review the efficacy of the strategies to reduce the incidence of these infections and the trend of results in Iran. As a routine, all hemodialysis patients in Iran have biannual blood samples for assessment of serum HBSAg, HBS Abs, and HCV Abs. The data are collected in the Ministry of Health. For statistical analysis, prevalence, and incidence were calculated. There is an increasing prevalence/incidence of end-stage renal disease (ESRD) in Iran, from 238/49.9 pmp in 2000 to 357/63.8 pmp in 2006. The prevalence of positive HBSAg and HCV Abs decrease...

Construction and Analytical Application of Internal Amplification Controls (IAC) for Detection of Food Supply Chain-Relevant Viruses by Real-Time PCR-Based Assays

British Library Electronic Table of Contents (United Kingdom)

Internal amplification controls (IACs) were constructed for incorporation into real-time nucleic acid amplification assays for bovine polyomavirus, hepatitis A virus, hepatitis E virus, human adenovirus, human norovirus genogroup I, human norovirus genogroup II, murine norovirus and porcine adenovirus. The addition of optimised amounts of IAC into the assays did not affect the limits of detection for each specific target virus. A poorly performed extraction of viral nucleic acids was simulated, and the effectiveness of IACs in identifying failed assays was demonstrated. The IACs constructed in this study can be reliably used in their specific assays to provide a robust control that can be routinely applied in the analysis of foods for viruses.

A comparison of hepatic in vitro metabolism of T-2 toxin in rats, pigs, chickens, and carp

British Library Electronic Table of Contents (United Kingdom)

T-2 toxin, a highly toxic member of the type-A trichothecenes, is produced by various Fusarium moulds that can potentially affect human health. It is strongly cytotoxic for human hematopoietic progenitors. Alimentary toxic aleukia (ATA), a disease typically associated with human, is primarily induced by T-2 toxin. A comparison of the metabolism of T-2 toxin incubated with hepatocytes of rats, piglets, chickens, and the hepatic subcellular fractions (microsomes and cytosol) of piglets, chickens, rats, and carp (common carp and grass carp) was carried out. The activities of the recombinant pig CYP3A29 on the transformation of T-2 and HT-2 toxins were preliminary studied. Metabolites were identified by novel LC/MS-IT-TOF. Qualitative similarities and differences across the species were observ...

[Clinico-hormonal correlations in patients with chronic alcoholic intoxication].

[Characteristics of the clinical picture and course of chronic alcoholic intoxication in patients with various types of neuroendocrine changes].

Radioimmunochemical assay was used to study the hypophyseal and peripheral hormones activity in 60 patients with chronic alcoholism, stage II. A correlation has been established between the patient's age and prolactin and FSH concentrations, as well as between the duration of the recent hard drinking and the concentrations of prolactin, testosterone, FSH and interstitial cell stimulating hormone. It has been shown that the manifestation of the alcoholic abstinent syndrome depended on the prolactin concentration. The test sensitivity estimated by the prolactin level rise and the testosterone level reduction reached 92.3%. The specificity of the changes detected comprised 25%. A conclusion has been made that the disorders noted in the patients with chronic alcoholic intoxication can be used as an objective test in the alcoholism diagnosis. PMID:3936321

Stress-induced alterations in anxiety-like behavior and adaptations in plasticity in the bed nucleus of the stria terminalis

Clinical and hormonal indices of androgenic activity were compared in 118 males chronically intoxicated with alcohol. The population was divided into two groups with respect to their clinical and hormonal androgenic indices: 76 patients with (Group 1), and 46 patients without (Group 2) androgenic insufficiency. Distinct signs and syndromes of alcohol addiction were shown to correlate with the extent of cross-regulation impairment within hypothalamo-hypophyseo-gonadal system. This was particularly derived from comparison of clinical picture of chronic alcohol intoxication and hormone activity in the groups. Conventional therapy failed to restore the neuroendocrine indices that was apparently due to inhibition of cross-regulation links in the hypothalamo-hypophyseo-gonadal system at several stages of alcohol addiction.

In vulnerable individuals, exposure to stressors can result in chronic disorders such as generalized anxiety disorder (GAD), major depressive disorder (MDD), and post-traumatic stress disorder (PTSD). The extended amygdala is critically implicated in mediating acute and chronic stress responsivity and anxiety-like behaviors. The bed nucleus of the stria terminalis (BNST), a subregion of the extended amygdala, serves as a relay of corticolimbic information to the paraventricular nucleus of the hypothalamus (PVN) to directly influence the stress response. To investigate the influence of the corticosteroid milieu and housing conditions on BNST function, adult C57Bl/6J were either acutely or chronically administered corticosterone (CORT, 25mg/kg in sesame oil) or vehicle (sesame oil) or were g...

Sexual function in women receiving maintenance dialysis

British Library Electronic Table of Contents (United Kingdom)

Abstract While substantial attention has been paid to the issue of sexual dysfunction in men on chronic dialysis, less is known about this problem in women with end-stage renal disease. We sought to assess sexual dysfunction in women on chronic dialysis and determine whether patients discuss this problem with their providers and receive treatment. We prospectively enrolled women receiving chronic hemodialysis or peritoneal dialysis in Pittsburgh, PA. We asked patients to complete the 19-item Female Sexual Function Index (FSFI) to assess sexual function and a 5-item survey that assessed whether patients had discussed sexual dysfunction with their providers and/or received treatment for this problem in the past. We enrolled 66 patients; 59 (89%) on hemodialysis and 7 (11%) on peritoneal dial...

Magnetic resonance imaging of chronic aortic dissection

Lipid composition of liver microsomes and mitochondria after acute and chronic {gamma}-irradiation of rats

17 patients with chronic aortic dissection were examined by MRI. In 12 patients, comparison between gradient echo sequences and SE sequences was possible. Gradient echo sequences, unlike SE sequences, permitted evaluation of flow in the true and false lumen, reliable differentiation between thrombus and flowing blood and clear delination of the intimal flap. An additional comparison between transoesophageal ultrasound and MRT in 15 patients showed significant advantages in favour of MRI. In three patients MRI was able to detect more proximal origins of the dissection. Moreover, MRI allowed evaluation of the major aortic branches and their relation to the dissection; this was not possible with ultrasound. MRI plays an important role in the follow-up of chronic aortic dissections. (orig.).

Intestinal Ischemia for estenosis of the superior mesenteric artery, Treatment with angioplastia and stent implant

Acute {gamma}-irradiation of rats at doses of 100 and 270 Gy stimulates lipid synthesis and changes the lipid composition of liver cell organelles. The content of cholesterol and cholesterol esters in microsomes increased at 100 Gy and decreased at 270 Gy, with total phospholipid content remaining unchanged. The lipid content in mitochondria decreased considerably 1 h after irradiation at 270 Gy. This change was significantly less pronounced 47 h later. Under chronic {gamma}-irradiation (0.129 Gy/day), cholesterol and cardiolipin in mitochondria increased. The changes in lipid content caused by acute irradiation are presumed to be related to activated synthesis of lipids in the liver. The modification of the lipid content of mitochondria observed in chronically irradiated rats may indicate that energy-metabolizing liver cell systems are involved in the adaptation to irradiation.

Chronic maternal stress affects growth, behaviour and hypothalamo?pituitary?adrenal function in juvenile offspring

Twenty-two out of 31 patients with chronic renal failure and secondary hyperparathyroidism who underwent parathyroidectomy before operation underwent non-invasive image diagnosis of parathyroid glands by computed tomography (CT), scintigraphy with /sup 201/TlCl and /sup 99m/TcO/sup 4 +/, and/or ultrasonography. CT visualized 39 of 45 parathyroid glands (86.7%), weighing more than 500 mg. Scintigraphy with a subtraction method using a computer performed the diagnosis in 19 of 27 glands (70.4%). Ultrasonography detected 21 of 27 glands (77.8%). Image diagnosis was also useful in the postoperative follow-up study. The non-invasive image diagnosis of parathyroid glands in patients with chronic renal failure is thus valuable for 1) definite diagnosis of secondary hyperparathyroidism, 2) localization, and 3) diagnosis for effectiveness of conservative treatment.

Maternal stress during pregnancy, particularly that combined with low socioeconomic status (SES), has been linked to an increased risk for impaired behavioural and emotional development and affective disorders in children. In animal models, acute periods of prenatal stress have profound effects on hypothalamo-pituitary-adrenal (HPA) function and behaviour. However, few studies have determined the impact of chronic exposure to stress in animal models. The objective of this study was to determine the effects of chronic maternal stress (CMS) during the 2nd half of pregnancy and nursing on growth, locomotor behaviour and HPA axis function in juvenile guinea pig offspring. Pregnant guinea pigs were exposed to a random combination of variable stressors every other day over the 2nd half of gestat...

Evaluation of support groups for women with breast cancer: importance of the navigator role

In the paper six cases of facial osteomyelitis as a complication of chronic sinusitis in hemophiliac-AIDS patients are reported. Osteomyelitis was suggested by an increasing of erythrocyte sedimentation rate. The diagnosis was confirmed by a positive {sup 99m} Tc MDP scintigraphy. The patients were submitted to clinical treatment. The erythrocyte sedimentation rate and 67-gallium citrate scans were used in the follow-up of the therapy. Three patients had negative gallium after three weeks of organism-specific antibiotic therapy; in two patients the gallium scintigraphy remained positive. One patient did not undergo the radionuclide scan for this clinical conditions. These results suggest that MDP scans showed higher sensitivity and specificity in detection of bone disease in chronic sinusitis. Gallium scans appeared to be valuable tool in the follow-up of the infection. There are no reports in the literature of osteomyelitis as a complication ...

Botulinum toxin—Beyond wrinkles

Over the years, nurses, doctors and scientists have sought ways of assessing the impact of pain on patients. While many of the instruments devised have been extremely useful in identifying the nature and intensity of pain, defining the effect it has on people's lives and perceptions has proved much more problematic. Based on the work she carried out with patients suffering from chronic benign pain, Karen Rose explores one aspect of these effects--the feeling of isolation. By using a four-step anthropological approach to identify the impact of pain, she argues, nurses can arrive at a realistic and accurate assessment of how patients are coping. PMID:7947167

Botulinum neurotoxin is produced by the bacterium, Clostridium botulinum. The neurotoxin inhibits acetylcholine at the neuromuscular junction, thus interfering with overall muscular contraction. Botulinum neurotoxin is commonly used for the following medical conditions: cervical dystonia, upper limb spasticity, blepharospasm, strabismus, and hyperhydrosis. However, the use of botulinum neurotoxin was recently approved for the prophylaxis of headaches in adults with chronic migraines. The proposed mechanism of botulinum neurotoxin is no longer solely limited to the inhibition of acetylcholine. There are new mechanisms emerging that involve inhibition of proinflammatory agents and neuropeptides involved in chronic pain. Consequently, there is a disruption of the overall sensory feedback loop...

Bilateral lipoma arborescens of the bicipitoradial bursa

A pain management program for chronic cancer-treatment-related pain: a preliminary study.

A 37-year-old military mechanic presented to our institution with a chronic history of a slowly enlarging left elbow antecubital fossa mass. There was no history of other chronic illness or trauma. Magnetic resonance imaging (MRI) and excisional biopsy revealed fatty villi and synovial inflammation within the left bicipitoradial bursa, consistent with lipoma arborescens. Four years later the patient presented with a 6-month history of swelling at the antecubital fossa of the opposite elbow. Diagnostic computed tomography and MRI examinations were performed. The surgical and pathologic findings confirmed the imaging diagnosis of lipoma arborescens at the right bicipitoradial bursa. (orig.)

Shellfish depuration by gamma irradiation: Final report for the period October 1, 1985-September 30, 1986

A large proportion of patients may develop chronic pain following cancer treatments such as surgery, radiotherapy, or chemotherapy. These patients can experience significant levels of physical and psychological morbidity. Our aim was to investigate a cognitive-behavioral pain management program (PMP) for cancer patients with chronic treatment-related pain. Thirteen patients (1 man, 12 women; mean age 52 yrs) completed the study, 9 of whom had a history of breast cancer and had received extensive medical treatment, including surgery. A combination of physical and psychological techniques were adapted from previous work in chronic benign pain and implemented by two therapists. Interventions included education, relaxation, exercise training, and goal setting. A variety of outcomes were examined to assess general fitness, psychological distress, coping success, activities of daily living, and pain report. The median number of ...

Rearrangement of a common cellular DNA domain on chromosome 4 in human primary liver tumors

Irradiation of live bivalve molluscs is a promising new technique to reduce the public health threats of viral and bacterial pathogens in the consumption of raw shellfish. In studies conducted within the past year, live hardshelled clams and oysters were innoculated with Simian Rotavirus SA-11, Poliovirus I, and Hepatitis-A virus and treated with gamma ray ionizing radiation from University of Lowell/DOE 800,000 Curie "6"0Co source over a dose range of 0.5--10 kiloGray (50--1000 kilorad) to determine the effectiveness of the process in eliminating viral activity and thus easing the potential viral health threats associated with uncooked bivalves. Two viral strains, SA-11 and Poliovirus I, were employed as models to perfect laboratory technique and to estimate the most appropriate range of dose exposures necessary for optimal inactivation of the infectious pathogen, Hepatitis A. Post-irradiation survivorship of the oysters and quahogs was ...

Rearrangement of a common cellular DNA domain on chromosome 4 in human primary liver tumors

Hepatitis B virus (HBV) DNA integration has been shown to occur frequently in human hepatocellular carcinomas. The authors have investigated whether common cellular DNA domains might be rearranged, possibly by HBV integration, in human primary liver tumors. Unique cellular DNA sequences adjacent to an HBV integration site were isolated from a patient with hepatitis B surface antigen-positive hepatocellular carcinoma. These probes detected rearrangement of this cellular region of chromosomal DNA in 3 of 50 additional primary liver tumors studied. Of these three tumor samples, two contained HBV DNA, without an apparent link between the viral DNA and the rearranged allele; HBV DNA sequences were not detected in the third tumor sample. By use of a panel of somatic cell hybrids, these unique cellular DNA sequences were shown to be located on chromosome 4. Therefore, this region of chromosomal DNA might be implicated in the formation of different ...

The preS2 antigens of hepatitis B virus (HBV), which causes a serious health problem in the world, have been implicated in hepatocyte cell binding and viral penetration. Therefore, the importance of antibody production against preS2 antigen for early diagnosis of HBV has been well established. In this study, the recombinant HBV preS2 single chain variable fragment (scFv) antibody was successfully expressed in E. coli with the novel cold shock vector (pCold) under the cspA promoter, and its expression level was compared with the pET vector under the T7 promoter. Additionally, a host with an oxidizing cytoplasm, E. coli trxB/gor double mutant, was used to improve the soluble expression. The anti-HBV preS2 scFv using pCold vector was successfully expressed in a soluble and functional form in ...

Diagnosis and therapy of Budd-Chiari syndrome; Diagnostik und Therapie des Budd-Chiari-Syndroms

Technetium-99m DISIDA hepatobiliary agent in diagnosis of hepatocellular carcinoma: relationship between detectability and tumor differentiation

Purpose: Budd-Chiari syndrome is a fairly uncommon disease in Europe. This often leads to its late diagnosis. The syndrome is characterised by portal hypertension and splanchnic congestion due to obstruction of hepatic venous outflow. This paper describes the treatment of three patients with Budd-Chiari syndrome by interventional therapeutic techniques and discusses alternative treatment modalities. Patients and Methods: The first patient presented with veno-occlusive disease and was treated by the placement of a transjugular intrahepatic portosystemic stentshunt. The second patient showed an occlusion of the major hepatic veins. After percutaneous recanalisation, a stent was placed in the right hepatic vein which remained patent. The third patient had a membranous obstruction of the right hepatic vein which was treated by percutaneous balloon dilatation. Results: In all patients the clinical symptoms ...

Intrahepatic peripheral cholangiocarcinoma; dynamic features of CT scans

The present investigation was aimed to assess the usefulness of biliary agents scintigraphy in the diagnosis of hepatocellular carcinoma (HCC) and to ascertain the relationship between the uptake of these agents and the degree of HCC differentiation. Forty-four patients with this hepatic cancer were included in the study. Liver scans were performed 20 min and 3 hr after the administration of 99mTc diisopropyliminodiacetic acid (DISIDA). DISIDA scintigraphy could not be assessed in six cases. In 16 (42%) out of the remaining 38 patients, the tumor exhibited equal or greater radioactivity uptake than the surrounding liver. In six out of these 16 patients, tumor uptake was apparent in the early and delayed hepatic scans, while in the other ten subjects radioactivity uptake by the HCC could only be detected in the 3-hr delayed scans. In the remaining 22 patients, HCC appeared as a cold area. Tumor location by this technique did not differ from that ...

Functional and physical molecular size of the chicken hepatic lectin determined by radiation inactivation and sedimentation equilibrium analysis

To elucidate the dynamic features of CT scans in peripheral cholangiocarcinoma for the differentiation of this tumor from various primary hepatic neoplasms. Materials were 24 cases of pathologically confirmed peripheral cholangiocarcinoma. Contrast enhancement patterns of central and peripheral portion of the masses were analyzed at three phases including arterial dominant(22), tissue equilibria(24), and postequilibria(9).

Expression and function of fibroblast growth factor (FGF) 9 in hepatic stellate cells and its role in toxic liver injury

Radiation inactivation and sedimentation equilibrium analysis were used to determine the functional and physical size of the chicken hepatic membrane receptor that binds N-acetylglucosamine-terminated glycoproteins. Purified plasma membranes from chicken liver were irradiated with high energy electrons and assayed for 125I-agalactoorosomucoid binding. Increasing the dose of ionizing radiation resulted in a monoexponential decay in binding activity due to a progressive loss of binding sites. The molecular mass of the chicken lectin, determined in situ by target analysis, was 69,000 +/- 9,000 Da. When the same irradiated membranes were solubilized in Brij 58 and assayed, the binding protein exhibited a target size of 62,000 +/- 4,000 Da; in Triton X-100, the functional size of the receptor was 85,000 +/- 10,000 Da. Sedimentation equilibrium measurements of the purified binding protein yielded a lower limit molecular weight of 79,000 +/- 7,000. However, the ...

Correct diagnosis of vascular encasement and longitudinal extension of hilar cholangiocarcinoma by four-channel multidetector-row computed tomography

Hepatic injury and regeneration of the liver are associated with activation of hepatic stellate cells (HSC). Fibroblast growth factors (FGFs) and their receptors are important regulators of repair in various tissues. HSC express FGFR3IIIc as well as FGFGR4 and different spliced FGFR1IIIc and FGFR2IIIc isoforms which differ in the presence or absence of the acid box and of the first Ig-like domain. Expression of FGF9, known to be capable to activate the HSC FGFR2/3-isoforms, was increased in HSC in liver slice cultures after exposition to carbon tetrachloride, as an acute liver injury model. FGF9 significantly stimulated 3-H thymidine incorporation of hepatocytes, but failed to induce DNA synthesis in HSC despite the fact that FGF9 induced a sustained activation of extracellular signal-related kinases (ERK) 1/2. FGF9 induced an increased phosphorylation of Tyr436 of the fibroblast growth factor receptor substrate (FRS) 2, while phosphorylation ...

Assessment of arterial tumor vascularity in small hepatocellular carcinoma. Comparison between color Doppler ultrasonography and radiographic imagings with contrast medium: dynamic CT, angiography, and CT hepatic arteriography

Accurate diagnosis of local invasion of hilar cholangiocarcinomas is challenging due to their small size and the anatomic complexity of the hepatic hilar region. On the other hand, the correct diagnosis of local invasion is essential for assuring the possibility of curative surgery. The purpose of this study was to evaluate the feasibility of four-channel multidetector-row computed tomography (MDCT) in the assessment of vascular and bile duct involvement, by which we could obtain useful information for the surgical management of hilar cholangiocarcinoma. The subjects were 18 patients for whom the extent of tumor invasion was surgically and pathologically confirmed. All patients underwent preoperative multiphasic CT scanning by MDCT. Arterial and portal dominant phases were acquired using a detector configuration of 1.25 mm x 4 mm, and both axial and multiplanar reconstructed images were interpreted. Longitudinal extension was evaluated up to second-order branches. ...

MRI in preoperative evaluation of chronic paranasal sinusitis - a comparison with CT

Hepatocellular carcinoma (HCC) is characterized by tumor vascularization from the hepatic artery. The objective of our work was to compare color Doppler ultrasonography (CDU), including power Doppler ultrasonography (PDU) with radiographic imagings with contrast medium in regard to the detection of the arterial tumor vascularity of small hepatocellular carcinomas (HCC). We examined 42 small HCC lesions 2 cm or less in diameter in 37 patients for arterial tumor vascularity by conventional CDU, PDU, dynamic computed tomography (dCT), digital subtraction angiography (DSA), and CT hepatic arteriography (CTA). Color images were detected in 25 (59.5%) and 28 (66.7%) of the 42 lesions with conventional CDU and PDU, respectively, and tumor vascularity was detected in 26 (61.9%) by dCT, 23 (54.8%) by DSA, and 29 (69.0%) by CTA. Tumor vascularity could be detected in 51.9% by PDU and CTA, more than by conventional CDU, dCT, and DSA (44.4, 44.4, and ...

Increase in phorbol ester binding in liver microsomes after chronic administration of phenobarbital

Purpose: To determine the value of MRI in the preoperative evaluation of chronic paranasal sinusitis and to compare the results with CT and intraoperative findings. Method/Materials: 42 patients with clinical signs of chronic paranasal sinusitis underwent MRI after CT evaluation on one day, with subsequent functional endoscopic sinus surgery on the next day. Coronary CT was obtained with 5-mm slices and table-feed in the prone position, while MRI was performed in the supine position with coronary T_2-TSE+pd and coronary and transverse HASTE, each with 5-mm slice thickness. Aquisition time in MRI was less than 8 minutes. Two radiologists reviewed the CT and MRI scans for signs of sinusitis and detection of anatomical landmarks. The results were correlated with the intraoperative findings. Results: MRI offered no artifacts of dental work and showed more often high quality pictures than CT. CT and MRI demonstrated a good correlation in the ...

Hemodynamic characterization of chronic bile duct-ligated rats: effect of pentobarbital sodium

The effect of chronic administration of phenobarbital on the binding of phorbol-12,13-dibutyrate (({sup 3}H)PDBu), an activator of protein kinase C (PKC), was examined in rat liver microsomes. A significant increase in the number of binding sites was observed in microsomes of Fisher 344 rats. However, no change appeared in liver cytosol binding of PDBu. Consequently, a translocation process of PKC is unlikely. The increase in ({sup 3}H)PDBu binding in liver microsomes is significant 24 h. after one injection of phenobarbital and reaches its maximum in 2 days. In other strains of rats (ACI and lean Zucker), significant differences were found in the increase of ({sup 3}H)PDBu binding in microsomes. Fisher 344 were the most sensitive, lean Zucker rats, the least sensitive. Those results parallel the pentoxy-resorufin O demethylase activity in the microsomes of the same animals. EC{sub 50} values for inhibition of ({sup 3}H)PDBu binding by pentobarbital were determined ...

Changes in myocardial beta1-adrenergic receptor and stimulatory G-protein gene expression after chronic treatment with doxorubicin in rat.

Systemic and splanchnic hemodynamics of the chronic bile duct-ligated rat were characterized by radioactive microspheres. Conscious and pentobarbital sodium-anesthetized, bile duct-ligated and sham-operated rats had cardiac output and regional organ blood flows determined. The conscious bile duct-ligated rat compared with the sham-operated showed a hyperdynamic circulation with an increased cardiac output and portal tributary blood flow. Pentobarbital sodium anesthesia induced marked hemodynamic changes in both sham-operated and bile duct-ligated rats. The latter group was especially sensitive to its effects; thus, comparison of cardiac output and portal tributary blood flow between anesthetized bile duct-ligated and sham-operated rats showed no significant differences. The authors conclude that the rat with cirrhosis due to chronic bile duct ligation is an excellent model for hemodynamic investigations but should be studied in the conscious ...

[Functional state of the hypothalamo-hypophyseal-gonadal system in patients with chronic alcoholic intoxication].

The gene expression of beta(1)-adrenergic receptor (beta(1)AR) and stimulatory G-protein Gsalpha in ventricle after chronic treatment with doxorubicin (DOX) in rat was investigated. The rats were treated with DOX in a dose of 2.5 mg/kg once a week for 5 weeks, the cumulative dose being 12.5 mg/kg. Two weeks after the last injection, the positive inotropic effect of isoproterenol was noticeably decreased in left atrial muscle preparations isolated from DOX-treated rats. Northern blot hybridization showed that the mRNA transcripts of beta(1)AR and Gsalpha, important signal transduction elements for regulating heart rate and contractility, were significantly decreased in the ventricle of DOX-treated rats. Thus, chronic treatment with DOX decreases the gene expression levels of myocardial beta(1)AR and Gsalpha. PMID:15353854

Reliability and validity of the PedsQL? Multidimensional Fatigue Scale in Japan

The function of the hypothalamo-pituitary-gonadal system has been studied in 118 males with different stages of alcoholism. Comparison with the control group has shown decreased levels of interstitial cell stimulating hormone (ICSH), follicle-stimulating hormone (FSH), and testosterone, and elevated concentrations of prolactin (Prl). Differences in the parameters of hormonal activity expressed in a varying degree of a decrease in FSH, ICSH, and testosterone, and a Prl elevation are related to change in mutual regulatory influences between the gonads and hypothalamo-pituitary complex. The most informative parameters were concentrations of Prl and testosterone (considering elevation in the former and reduction in the latter hormone) and the ratio of their concentrations. Difference of these parameters in each group (corresponding to the stages of alcoholism) may be used as an additional diagnostic criterion of chronic alcohol intoxication. PMID:3434080

Pyridostigmine interaction with soman during chronic exposure in rodents. Interim report, February-November 1987

Psychological distress and investment in one-s appearance in patients with pemphigus

The effects of repeated low-level nerve agent exposure on animal performance and lethality are a major concern of USAF Medical Research. This concern has generated interest in the role that pretreatment drugs such as pyridostigmine may play during simultaneous exposure to soman. This role was investigated by recording lethality, weights, symptoms, and cholinesterase (ChE) inhibition in rats chronically exposed to 4 levels of soman (32, 39, 48 or 59 micrograms/kg/day) while simultaneously receiving 10.0 milligrams/kg/day pyridostigmine, 1.0 milligrams/kg/day pyridostigmine, or vehicle via an osmotic pump. No effect (either protective or detractive) was found in the soman-poisoned animals due to the presence or absence of pyridostigmine. However, rat blood biochemistry is different from that of the primate, warranting further study in the primate before extrapolation to man.

PREVENTION OF INFECTION IN PATIENTS WITH CHRONIC KIDNEY DISEASE PART III: SURVEILLANCE AND AUDITING IN A RENAL CARE ENVIRONMENT

British Library Electronic Table of Contents (United Kingdom)

Summary This third paper, in a three-part CE series on the preventions of infection in patients with chronic kidney disease, focuses on surveillance and auditing of healthcare-associated infections within the renal care environment. The last decade has seen an increased awareness of the threat to patient safety from healthcare-associated infection (HCAI) and the emergence of multi-drug resistance organisms. Effective HCAI prevention strategies include adequate governance structures, access to expert advice, adherence to standard and transmission-based precautions, minimising the use of invasive medical devices, and surveillance. Surveillance data can be collected using outcome (e.g. infection) and/or process (e.g. hand hygiene compliance audit) measures. Establishing a surveillance program...

No detectable XMRV in subjects with chronic fatigue syndrome from Quebec

British Library Electronic Table of Contents (United Kingdom)

We investigated the presence of XMRV in a cohort of Quebec patients with chronic fatigue syndrome (CFS). DNA was purified from activated peripheral blood mononuclear cells (PBMCs) and PCR was used to detect XMRV gag and env in 72 patients. Anti-XMRV antibodies were searched in sera of 62 patients by Western blot analysis. Attempts to detect XMRV antigens was made, using immunofluorescence with Gag anti-p30 antiserum on activated PBMC from 50 patients. Plasma viremia was measured by RT-PCR on 9 subjects. Finally, detection of infectious virus in 113 CFS subjects was made by co-culture of PHA+IL-2 activated PBMC with human LNCaP carcinoma cells, and by infecting the same susceptible cells with plasma, using a reverse transcriptase (RT) assay as a readout in both experiments. No detection of ...

Diesel exhaust inhalation induces heat shock protein 70 expression in vivo

British Library Electronic Table of Contents (United Kingdom)

Exposure to urban air pollution is an independent risk factor for increased cardiovascular diseases. Heat shock protein 70 (HSP70) has been implicated in the pathogenesis of vascular dysfunction and cardiovascular diseases. This study has been designed to determine whether inhalation of urban air induces HSP70 expression in the lung and blood as well as the association of HSP70 and air pollution-induced vascular dysfunction. Apolipoprotein E (Apo-E) deficient mice were exposed to diesel exhaust (DE) either acutely (3 days, 200 or 400 g/m3 for 6 h/day) or chronically (7 weeks, 200 or 400 g/m3 for 6 h/day). HSP70 was measured in the lung using immunohistochemistry, and in the plasma by ELISA. Abdominal aorta rings were used to determine vascular functional responses. Chronic DE-exposure incr...

Detecting retroviral sequences in chronic fatigue syndrome.

Cyclooxygenase expression and prostaglandin levels in central nervous system tissues during the course of chronic relapsing experimental autoimmune encephalomyelitis (EAE)

XMRV or xenotropic murine leukemia virus-related retrovirus, a recently discovered retrovirus, has been linked to both prostate cancer and chronic fatigue syndrome (CFS). Recently, the teams of Drs. Shyh-Ching Lo and Harvey Alter discovered the presence of sequences closely related to XMRV in the blood of 86.5% of patients with CFS [1]. These findings are important because since the initial discovery of XMRV in CFS, several studies have failed to find XMRV in specimens collected from CFS patients. While the current study also did not find XMRV in CFS, Lo et al. did detect sequences that belong to polytropic mouse endogenous retroviruses (PMV), which share considerable similarity with XMRV. Criteria for future studies that will help bring greater clarity to the issue of retroviral sequences in CFS are proposed below. PMID:21994623

Objective Multiple sclerosis (MS) and its animal counterpart experimental autoimmune encephalomyelitis (EAE) have a major inflammatory component that drives and orchestrates both diseases. One particular group of mediators are the prostaglandins (PGs), which we have previously shown, through quantitation and pharmacological intervention, to be closely involved in the pathology of MS and EAE. The aim of the current study was to determine the expression of the PG-generating cyclooxygenase (COX) enzymes and the profile of PGE2 and PGD2, in selected central nervous system (CNS) tissues, with the development of the chronic relapsing (CR) form of EAE. In particular, the work investigates the possible relationship between the expression of COX isoenzymes and PG levels during the neurological phas...

Chronic sympathetic activation promotes downregulation of ?-adrenoceptor-mediated effects in the guinea pig heart independently of structural remodeling and systolic dysfunction

British Library Electronic Table of Contents (United Kingdom)

It is uncertain if downregulation of ?-adrenoceptor signaling pathway is promoted by an enhanced adrenergic tone at an early stage of cardiac disease, or it develops secondary to detrimental local myocardial changes in advanced heart failure. We examined the integrity of ?-adrenoceptor signaling pathway upon chronic infusion of isoproterenol, a ?-adrenoceptor agonist, at a dose producing no structural left ventricular (LV) remodeling and systolic dysfunction. Subcutaneous isoproterenol infusion (400??g?kg?1?h?1 over 16?days) to guinea pigs using osmotic minipumps produced no change in cardiac weights, LV internal dimensions, myocyte cross-sectional area, extent of interstitial fibrosis, and basal contractile function.

Chronic irradiation and brain development. Final (4th) progress report

Chronic inflammation and mortality in haemodialysis: effect of different renal replacement therapies. Results from the RISCAVID study

The possible long term effects of chronic radiation exposure have been studied. Rats were given tritiated drinking water (3#mu#Ci/ml) before pregnancy, during pregnancy and threafter, continuously through 5 generations. The brains were studied at 30 and 120 days postnatally. Significant decreases in weight, DNA and protein contents of specific parts of the brain were found, the most pronounced decreases being in the diencephalon. The decreases in protein content were more pronounced than the decreases in DNA content; the decreases were also more pronounced at 30 days than at 120 days, and more pronounced in the fifth generation than in previous generations. An attempt was made to explain these complex phenomena on the basis of known periods of proliferation of various brain cells, damage to mothers themselves in each generation, and damage and repair of nucleic acids caused by radioactivity.

Analysis of cerebrospinal fluid from chronic fatigue syndrome patients for multiple human ubiquitous viruses and xenotropic murine leukemia-related virus

British Library Electronic Table of Contents (United Kingdom)

Abstract Recent reports showed many patients with chronic fatigue syndrome (CFS) harbor a retrovirus, xenotropic murine leukemia-related virus (XMRV), in blood; other studies could not replicate this finding. A useful next step would be to examine cerebrospinal fluid, because in some patients CFS is thought to be a brain disorder. Finding a microbe in the central nervous system would have greater significance than in blood because of the integrity of the blood-brain barrier. We examined cerebrospinal fluid from 43 CFS patients using polymerase chain reaction techniques, but did not find XMRV or multiple other common viruses, suggesting that exploration of other causes or pathogenetic mechanisms is warranted.

The biodistribution and effect on hepatic parenchyma with intraarterial injected I-131 lipiodol into hepatic artery

[Hormonal disorders in chronic alcoholic intoxication].

Iodized oil has been used as a contrast agent in lymphangiography. One of the commercially available compounds is Lipidol Ultra-fluid(LUF) which contains 38% iodine by weight. Nakakuma et al(1979) reported that LUF was selectively retained in the hypervascular hepatocellular carcinoma when injected directly into the ligated hepatic artery. Since that time, it has been widely utilized in the detection as well as the therapeutic attempts of hepatocellular carcinoma, where it has been mixed with chemotherapeutic agents or labeled with radioactive I-131. Like all significant advances, the mechanism of lipid retention within the hepatocellular carcinoma is not clearly understood, and also there is a lack of information about the biodistribution and kinetics of I-131 Lipiodol. The apparent safety of this technique require confirmation. The present study was aimed to assess the biodistribution and kinetics of intraarterially injected I-131 Lipiodol and the histologic ...

Particulate air pollution and chronic ischemic heart disease in the eastern United States: a county level ecological study using satellite aerosol data

The effect of in vitro and in vivo administration of ethanol on the binding of "3"5S-t-butyl-bicyclophosphorothionate ("3"5S-TBPS) to cortical brain membranes of C57B1 mice was investigated using KCl (100 mM) containing assay media. The in vitro addition of ethanol produced a dose-dependent inhibition of basal "3"5S-TBPS binding. In the presence of chloride ions, GABA and pentobarbital had a biphasic action (stimulation followed by inhibition) on "3"5S-TBPS binding, whereas diazepam only stimulated the binding. Ethanol reduced the stimulatory effects of GABA and pentobarbital in a dose-dependent manner, but had no effect on the enhancement of "3"5S-TBPS binding produced by diazepam. "3"5S-TBPS binding to cortical brain membranes was inhibited by the putative Cl"- channel blocking agent DIDS. This inhibitory action of DIDS was significantly, and dose-dependently reduced by ethanol (#<=# 100 mM ethanol). Chronic ethanol ingestion in vivo, which produced tolerance ...

Monoclonal antibodies specific for the outer surface protein A (OspA) of Borrelia burgdorferi prevent Lyme borreliosis in severe combined immunodeficiency (scid) mice.

Mucociliary transport so critical in nasal, paranasal sinus, and middle ear physiology is impaired in chronic sinsusitis and otitis media by factors such as increased mucus viscoelasticity, decreased ciliary area, and primary or secondary ciliary immotility. We reviewed the pathophysiology of primary ciliary dyskinesia, otitis media with effusion, chronic sinusitis, and allergic rhinitis in terms of mucociliary transport. Subjects with primary ciliary dyskinesia may experience recurrent middle ear infection, chronic airway infection, predominantly lower-lobe bronchiectasis, male sterility, or situs inversus. Primary ciliary dyskinesia is sometimes difficult to diagnose in cases without situs inversus. Nasal nitric oxide concentration in such patients decreases, although why is unclear. Mutations may involve dynein arm intermediate chain 1 (DNAI1) or dynein arm heavy chain 5 (DNAH5). Mucociliary clearance decreases more in ...

Insights in the use of health care services in chronic benign pain in childhood and adolescence.

By polymerase chain reaction with arbitrary primer (AP-PCR), the possibility of transmission of genome instability to somatic cells of the offspring (F_1 generation) from male parents of mice exposed to chronic low-dose #gamma#-radiation was studied. Male mice 15 days after exposure to 10-50 cGy were mated with unirradiated females. Biopsies were taken from tale tips of two month-old mice progeny for DNA separation. Primer in the AP-PCR was 20-mer oligonucleotide flanking the micro-satellite locus Atplb2 on chromosome 11 of the mouse. Comparative analysis of individual fingerprints of AP-PCR products on DNA-templates from the offspring of irradiated and unirradiated male mice revealed an increased variability of micro-satellite-associated sequences in the genome of the offspring of males exposed to 25 and 50 cGy. DNA-fingerprints of the offspring of male mice exposed to chronic irradiation doses 10 and 25 cGy. 15 days before fertilization (at ...

Commentary

Cerebral sparganosis. Case report.

1. It is not possible to give a threshold value for the dose - nor for genetic neither for somatic late effects. 2. The linear dose-effect exprapolation is not conservative in the sense of 'fying on the safe side'. 3. There has been found no relative reduction of the effects at chronic radiation exposure in man. 4 The numbers given by authorities and utilities for damage rates per rem received, that are called upper limits, are by far too low. (orig./HP).

Cellular Sources of Transforming Growth Factor-? Isoforms in Early and Chronic Radiation Enteropathy

The tapeworm Spirometra mansonoides infects man worldwide, particularly in Asian countries. Rarely, the central nervous system is involved; such a case is presented here. In the total of 12 reported cases, including the case described, the worm presented clinically as a mass suspicious for neoplasm or chronic abscess cavity. Surgical removal was invariably curative in each case. Although infrequent, the possibility of tapeworm infection should be entertained in the evaluation of intracranial masses in patients who have visited exotic locales. PMID:2191089

CT manifestations of ileal dysgenesis

Computed tomography was performed on 5 patients with chronic cerebral paragonimiasis. CT showed solitary or multiple, amorphous, round, or oval calcifications, and ventricular enlargement in all 5 cases. A large low-density area is also found in 4 of the 5 cases. These CT findings are compatible with previously reported findings of simple X-ray films of the skull, pneumoencephalography, and pathological studies. (author).

Biological effects and health risks following to the exposition to ionizing radiation

Ileal dysgenesis is an uncommon condition of unknown etiology occurring in the distal ileum in the region of the vitelline duct. The CT appearance of this lesion, although not previously described to our knowledge, is characteristic. We report a patient with ileal dysgenesis who had an abdominal CT scan to evaluate chronic iron deficiency anemia and protein-losing enteropathy. Recognition of this lesion by pediatric radiologists is important; so that surgical treatment, which is simple and effective, can be initiated quickly. (orig.)

Treatment of hepatocellular carcinoma (HCC) with radiolabeled Lipiodol: a preliminary report

Late somatic and genetic radiation effects are imperfectly understood, particularly in the human species. However the available information is sufficient to draw reasonably precise risk estimates in man for many types of damage by means of scientifically justifiable procedures and with the necessary caution. This overall absolute risk of major somatic and genetic damage may be set at around 10"-"4/rad of chronic whole-body doses.

The disruption of l-carnitine metabolism by aluminum toxicity and oxidative stress promotes dyslipidemia in human astrocytic and hepatic cells

Fatty acid esters such as Lipiodol or Ethiodol are known to selectively localize in vascular hepatocellular carcinomas (HCC), following intraarterial hepatic administration. Lipiodol was labeled with radioactive /sup 131/I and administered in 47 patients with HCC for both imaging and therapy. The short term preliminary results suggest radiolabeled Lipiodol is effective in eliminating ascites, shrinking the tumor by a high internal radiation dose, and in improving symptomatology of these tumors. In the future, /sup 90/Y, which is a stronger pure beta-emitter (maximum beta energy of 2.27 MeV, a half life of 64 h, and a maximum penetration or beta range of 11mm), than /sup 131/I will be used for more effective treatment of HCC.

l-Carnitine is a critical metabolite indispensable for the metabolism of lipids as it facilitates fatty acid transport into the mitochondrion where b-oxidation occurs. Human astrocytes (CCF-STTG1 cells) and hepatocytes (HepG2 cells) exposed to aluminum (Al) and hydrogen peroxide (H2O2), were characterized with lower levels of l-carnitine, diminished b-oxidation, and increased lipid accumulation compared to the controls. g-Butyrobetainealdehyde dehydrogenase (BADH) and butyrobetaine dioxygenase (BBDOX), two key enzymes mediating the biogenesis of l-carnitine, were sharply reduced during Al and H2O2 challenge. Exposure of the Al and H2O2-treated cells to a-ketoglutarate (KG), led to the recovery of l-carnitine production with the concomitant reduction in ROS levels. It appears that the chann...

Multidetector Computed Tomography in the Preoperative Workup of Hilar Cholangiocarcinoma

Molecular environment of the IIId subdomain of the IRES element of hepatitits C virus RNA on the human 40S ribosomal subunit

Hilar cholangiocarcinoma is associated with a dismal prognosis; however, curative resection may offer a chance of cure. Various factors should be considered in the surgical planning for curative resection. These factors include extent of bile duct involvement, relationship between portal vein and tumor involvement, diffuse hepato duodenal ligament infiltration, vascular invasion, lymph node metastasis, peritoneal seeding, and hepatic volume. Using high-quality volume data from multidetector-row computed tomography (MDCT) and adequate postprocessing images, radiologists can provide various types of information, imperative for curative resection of a hilar cholangiocarcinoma. This review illustrates the role of MDCT in the preoperative workup of hilar cholangiocarcinoma.

The molecular environment of the key subdomain IIId of the internal ribosome entry site (IRES) element of hepatitis C virus (HCV) RNA in the binary complex with the human 40S ribosomal subunit was studied. To this end, HCV IRES derivatives bearing perfluorophenylazido groups activatable by mild UV at nucleotides G263 or A275 in the subdomain IIId stem were used. They were prepared by the complementary addressed modification of the corresponding RNA transcript with alkylating oligodeoxyribonucleotide derivatives. None of the RNA derivatives were shown to be crosslinked to the 18S rRNA. It was found that the photoreactive groups of the IRES G263 and A275 nucleotides are crosslinked to ribosomal proteins S3a, S14, and S16. For the IRES derivative with the photoreactive group in nucleotide G26...

Lipiodol solution of a lipophilic agent, {sup 188}Re-TDD, for the treatment of liver cancer

Heated lipiodol as an embolization agent for transhepatic arterial embolization in VX2 rabbit liver cancer model

Radiolabeled lipiodol has been used for targeting liver cancer. We developed a lipiodol solution of {sup 188}Re-TDD (2,2,9,9-tetramethyl-4,7-diaza-1,10-decanedithiol) and investigated its feasibility for the treatment of liver cancer. The lipiodol solution of {sup 188}Re-TDD was well-retained in the lipiodol phase in vitro. After injection through the tail veins of mice, high lung-uptake was investigated which is evidence of embolizing activity. We also found high accumulation in hepatoma after injection through the hepatic arteries of hepatoma-bearing rats. In conclusion, the lipiodol solution of {sup 188}Re-TDD is a promising agent for liver cancer therapy.

Diphenyl diselenide and analogs are substrates of cerebral rat thioredoxin reductase: A pathway for their neuroprotective effects

Purpose: To evaluate the therapeutic effect of heated (60 deg. C) lipiodol via hepatic artery administration in a rabbit model of VX2 liver cancer. Materials and methods: Thirty male New Zealand white rabbits were randomly divided into three groups with 10 rabbits assigned to each group. VX2 carcinoma cells were surgically implanted into the left hepatic lobe. The tumors were allowed to grow for 2 weeks, and studies were performed until the diameter of the tumors detected by ultrasonograph reached 2-3 cm. Under anesthesia, trans-catheter hepatic arterial embolization was performed and doxorubicin-lipiodol (37 deg. C) (1 mL), lipiodol (60 deg. C) (1 mL) or control (physiological saline (37 deg. C) (1 mL)) solution was injected into the hepatic arteries of animals in the three groups. One week later, the volume of the tumor was measured by ultrasonograph again. The serum of all rabbits was collected ...

Thioredoxin reductase (TrxR) isoforms play important roles in cell physiology, protecting cells against oxidative processes. In addition to its endogenous substrates (Trx isoforms), hepatic TrxR can reduce organic selenium compounds such as ebselen and diphenyl diselenide to their selenol intermediates, which can be involved in their hepatoprotective properties. Taking this into account, the aim of the present study was to evaluate the hypothesis that ebselen, diphenyl diselenide and its analogs (4,4'-bistrifluoromethyldiphenyl diselenide, 4,4'-bismethoxydiphenyl diselenide, 4.4'-biscarboxy-diphenyl diselenide, 4,4'-bischlorodiphenyl diselenide, 2,4,6,2',4',6'-hexamethyldiphenyl diselenide) could be substrates of rat brain TrxR.

Detection of recurrence and the effect of transcatheter hepatic arterial embolization using lipiodol (Lp-TAE) assessed by the lipiodol accumulative pattern on CT

Automated preparation of Re-188 lipiodol for the treatment of hepatocellular carcinoma

We evaluated the relation between the lipiodol accumulative pattern on CT 1 month after 1st Lp-TAE and the effect of Lp-TAE and recurrence of hepatocellular carcinoma (HCC) in 70 cases undergoing Lp-TAE twice. The lipiodol accumulative pattern on CT can be classified into four types (I: homogeneous, II: defect, III: inhomogeneous, IV: no or slight). In the type I, recurrence of the main tumor was 26.7%, daughter was 73.7%, suggesting a good effect of Lp-TAE. In the types II, III and IV, recurrence of the main tumor was seen in 66.7%, 83.3% and 83.3%, respectively, suggesting that the effect of Lp-TAE was worse according to the lipiodol accumulative pattern on CT. The lipiodol accumulative pattern on CT is useful for the detection of recurrence and assessment of the effect of Lp-TAE. (author).

Radiofrequency Ablation of Intrahepatic Cholangiocarcinoma: Preliminary Experience

The iodinated oil lipiodol is commonly used as a carrier for in situ delivery of drugs or radioactivity to hepatic tumors. Recently, we reported a new kit formulation for high-activity labeling of lipiodol with the {beta}-emitting radionuclide Re-188. Since the whole preparation involves different steps and complex manipulations of high-activity samples, we describe here an automated synthesis module that allows the easy preparation of sterile and pyrogen-free samples of Re-188 lipiodol ready to be administered to the patient. Important advantages include the possibility to incorporate high Re-188 activity into the lipiodol hydrophobic phase and a sharp reduction of radiation exposure of the operator assisting the labelling procedure. Application of this modular reaction system could be also extended to the preparation of other Re-188 radiopharmaceuticals and to compound labelled with different {beta}-emitting therapeutic radionuclides.

Prospective benefit and effect of lipiodol marking in hepatocellular carcinoma; Moeglicher Nutzen und Auswirkung einer Lipiodolmarkierung auf die Histologie beim hepatozellulaeren Karzinom

The purpose of this study was to evaluate the safety and efficacy of percutaneous ultrasound (US)-guided radiofrequency ablation (RFA) in patients with intrahepatic cholangiocarcinoma (ICCA) in a small, nonrandomized series. From February 2004 to July 2008, six patients (four men and two women; mean age 69.8 years [range 48 to 83]) with ICCA underwent percutaneous US-guided RFA. Preintervetional transarterial embolization was performed in two cases to decrease heat dispersion during RFA in order to increase the area of ablation. The efficacy of RFA was evaluated using contrast-enhanced dynamic computed tomography (CT) 1 month after treatment and then every 3 months thereafter. Nine RFA sessions were performed for six solid hepatic tumors in six patients. The duration of follow-up ranged from 13 to 21 months (mean 17.5). Posttreatment CT showed total necrosis in four of six tumors after one or two RFA sessions. Residual tumor was observed in two patients with larger ...

Preparation and biodistribution of yttrium-90 lipiodol in rats following hepatic arterial injection

Purpose: To assess the benefit and the effect of intraarterial lipiodol application on histological analysis of patients suspected of having HCC. To determine whether lipiodol marking leads to a better biopsy result and how lipiodol or a transarterial chemoembolization influences the histological diagnosis. Materials and Methods: Two groups of patients were examined. Group A included 14 patients highly suspected of having an HCC which had previously been unsuccessfully biopsied. A transarterial embolization with lipiodol was performed in these patients to mark intrahepatic tumors which could not otherwise be defined in unenhanced CT. A biopsy was then repeated. Group B included 22 patients undergoing therapy using transarterial chemoembolization (TACE). A biopsy was performed to support the diagnosis of a multifocal HCC before changing the therapy. Results: The transversal diameters of the biopsied tumors were similar in both groups (A: 22 mm; B: 21 mm). The length of percutaneous ...

Patterns of vascular invasion of intrahepatic peripheral cholangiocarcinoma examined with angiography and angiographic CT

We labelled Lipiodol with yttrium-90 and analysed the biodistribution in rats after intrahepatic arterial injection. An RP-18 column was used to separate {sup 90}Y from strontium-90. {sup 90}Y was retained on the column, which had been pretreated with yttrium-selective extraction reagent, di(2-ethylhexyl) phosphate, while {sup 90}Sr was washed out. A hexadentate nitrogen-donor chelating ligand N,N,N`,N`-tetrakis(2-benzymidazolylmethyl)-1,2-ethanediamine (EDTB) was synthesized by condensation of 1,2-benzenediamine and ethylene diamine tetra-acetic acid (EDTA). Lipiodol was covalently conjugated with EDTB. The final product was obtained by eluting the retained {sup 90}Y from the RP-18 column with EDTB-Lipiodol. Sixteen male rats (Sprague-Dawley) were sacrificed at 1 h, 24 h, 48 h and 72 h (four rats at each time) after injection of approximately 0.1 mCi {sup 90}Y-Lipiodol via the hepatic artery.

Infection disclosure in the injecting dyads of Hungarian and Lithuanian injecting drug users who self-reported being infected with hepatitis C virus or human immunodeficiency virus.

To evaluate the radiological patterns of vascular invasion in peripheral cholangiocarcinomas. Hepatic arteriography and portography in 20 cases with cholangiocarcinoma including 12 cases with angiographic CT were retrospectively analyzed. The arteriography showed no arterioportal shunt, hypertrophy of tumor vessel, or tumor staining extending to central portion of the mass in all cases. However, doughnut shaped peripheral tumor staining was seen until late hepatogram phase in 12 cases and compensatory hyperperfusion around the mass was seen in six cases (eight cases if include arterial CT). Encasement of tumor vessel was seen in 12 cases, and hypertrophy of feeding vessel in nine cases. On portography, the filling defect on segmental portal branch could be demonstrated only in 11 cases. Shape of the portal defect was tapered narrowing in six cases, abrupt narrowing in two cases but intraluminal nodular filling defect was not seen. Remaining three cases were ...

Induction of lauric acid omega-hydroxylation by peroxisomal proliferators in bluegill and catfish

The aim of this study was to assess the prevalence and correlates of disclosure to network members of being hepatitis C virus (HCV)- or human immunodeficiency virus (HIV)-infected among injecting dyads of infected injection drug users (IDUs) in Budapest, Hungary and Vilnius, Lithuania,. Multivariate generalized estimating equations (GEE) were used to assess associations. Very strong infection disclosure norms exist in Hungary, and HCV disclosure was associated with using drugs and having sex within the dyad. Non-ethnic Russian IDUs in Lithuania were more likely to disclose HCV infection to non-Roma, emotionally close and HCV-infected network members, and to those with whom they shared cookers, filters, drug solutions or rinse water or got used syringes from, and if they had fewer non-IDU or IDU network members. Ethnic Russian Lithuanian IDUs were more likely to disclose HCV if they had higher disclosure attitude and knowledge scores, 'trusted' network members, and ...

Induction of biotransformation in the liver of Eel (Anguilla anguilla L. ) by sublethal exposure to dinitro-o-cresol: An ultrastructural and biochemical study

Peroxisome proliferating agents (PPAs) are a structurally diverse group of chemicals that include environmental chemical contaminants such as certain chlorinated herbicides, solvents and plasticizers. PPAs have previously been shown to induce anti-trout laruci acid hydroxylase immunoreactive proteins in bluegill and catfish. In this investigation, induction of lauric acid hydroxylase activity and immunoreactive proteins was confirmed, and the mass spectral analysis of specific hydroxylation products was performed in order to identify possible species-specific differences in fatty acid metabolism. Male bluegill (Lepomis macrochirus) and channel catfish (Ictalurus punctatus) were administered clofibrate or ciprofibrate 48 hr prior to hepatic or trunk kidney (catfish only) microsome preparation. While no significant differences were observed in male catfish, male bluegill had significant decreases in hematocrit and plasma protein indicating hemodilution due to ...

Four cases of solid pseudopapillary tumors of pancreas: Imaging findings and pathological correlations

Structural and functional alterations in hepatocytes of the European eel, Anguilla anguilla, following a 4-week-exposure to 5, 50, and 250 micrograms/liter dinitro-o-cresol (DNOC) were investigated by means of electron microscopy and biochemistry and compared to liver pathology in eels exposed to the chemical spill into the Rhine river at Basle in November 1986. Whereas phenological parameters (growth, condition factor) are unaffected, ultrastructural and biochemical alterations are detectable at greater than or equal to 50 and 5 micrograms/liter DNOC, respectively. Structural modifications include: rounding-up of the nuclei; fractionation and reduction of the rough endoplasmic reticulum; proliferation of the smooth endoplasmic reticulum (SER), mitochondria, peroxisomes, and lysosomes; bundles of rod-shaped SER profiles; annulate lamellae; membrane whorls within mitochondria; crystallization of the peroxisomal matrix and glycogen bodies; glycogen depletion and lipid augmentation. ...

Four cases of solid pseudopapillary tumors of pancreas: Imaging findings and pathological correlations

Objective: Solid pseudopapillary tumor of the pancreas (SPTP tumor) is a rare pancreatic neoplasm with low malignant potential, which usually affects female patients in the second or third decades of life. It is a non-functional, slow-growing neoplasm that very often reaches considerable size before the first symptoms appear. Symptomatology is frequently related to tumor size. Surgical excision is usually curative in most cases. Infrequently the tumor can appear in male patients or in aged women, which can make the diagnosis more difficult. Some patients develop liver metastases in the follow-up that can be resected. Our purpose is to review the radiological and pathological findings of SPTP with emphasis on these infrequent cases. Subjects and methods: The medical records and radiological findings of patients who underwent surgery for SPTP between 2000 and 2005 were retrospectively reviewed. Study eligibility required that patients had undergone surgical resection and that a SPTP had ...

CT findings of intrahepatic cholangiocarcinoma associated with hepatolithiasis

The effect of prenatal cimetidine exposure (PreCM) on the duration of pentobarbital-induced narcosis (DPN) was assessed in immature (14- and 28-day old) and adult (50-60-day old) male and female rats. PreCM exposure was accomplished by treating mothers with cimetidine (CM) (20 mg/kg, ip) daily for the last two days of gestation and then (0.01% in drinking water) throughout lactation. Pregnant mothers of untreated offspring (Con) received saline. PreCM decreased DPN to 505 +/- 33 min (from 611 +/- 23 min in Con) and 393 +/- 190 min (from 686 +/- 44 min in Con) in 14-day old male and female rats, respectively. Similarly, PreCM decreased DPN to 88 +/- 15 min (from 134 +/- 3 min in Con) and 102 +/- 19 min (from 171 +/- 44 min in Con) in 28-day old male and female rats, respectively. At 21 days, PreCM did not alter DPN in either sex. At 50-60 days, however, it decreased DPN to 144 +/- 41 min (from 238 +/- 7 min in Con) in females but had no effect in males; PreCM also increased the plasma ...

An experimental study on lipiodol chemoembolization in the normal dog liver

To assess the CT findings of intrahepatic cholangiocarcinoma associated with hepatolithiasis. The CT features of 26 patients with cholangiocarcinoma and hepatolithiasis were reviewed and compared with those of 23 patients with intrahepatic stones alone, acting as control subjects. CT findings were analyzed for tumor appearance and adjacency to hepatolithiasis. We studied clinical findings, noting the presence or absence of wall thickening or soft tissue attenuation within the bile duct, the luminal diameter of dilated bile duct, and the presence of periductal enhancement, and compared these with the findings for control groups. CT images of the tumor revealed a hepatic low-attenuating mass with peripheral rim enhancement(n = 14,54 %), or periductal thickening, or low-attenuating lesions in segmental dilatation of intrahepataic bile ducts(n = 12, 46 %). Most hepatic tumors were seen in areas adjacent to hepatolithiasis, or in a bile duct. ...

OSCAAR calculations for the Iput dose reconstruction scenario of BIOMASS theme 2

Pattern and model makers are skilled tradespersons who may be exposed to hardwoods, softwoods, phenol-formaldehyde resin-impregnated woods, epoxy and polyester/styrene resin systems, and welding and metal-casting fumes. The relationship of respiratory symptoms (wheezing, chronic bronchitis, dyspnea) and pulmonary function (FVC% predicted, FEV1% predicted, FEV1/FVC% predicted) with interview-derived cumulative exposure estimates to specific workplace agents and to all work with wood, plastic, or metal products was investigated in 751 pattern and model makers in southeast Michigan. In stratified analyses and age- and smoking-adjusted linear and logistic regression models, measures of cumulative wood exposures were associated with decrements in pulmonary function and dyspnea, but not with other symptoms. In similar analyses, measures of cumulative plastic exposures were associated with wheezing, chronic bronchitis, and dyspnea, but not with ...

Impairments of astrocytes are involved in the D-galactose-induced brain aging

This report presents the results obtained from the application of the accident consequence assessment code, called OSCAAR, developed in Japan Atomic Energy Research Institute to the Iput dose reconstruction scenario of BIOMASS Theme 2 organized by International Atomic Energy Agency. The Iput Scenario deals with {sup 137}Cs contamination of the catchment basin and agricultural area in the Bryansk Region of Russia, which was heavily contaminated after the Chernobyl accident. This exercise was used to test the chronic exposure pathway models in OSCAAR with actual measurements and to identify the most important sources of uncertainly with respect to each part of the assessment. The OSCAAR chronic exposure pathway models almost successfully reconstructed the whole 10-year time course of {sup 137}Cs activity concentrations in most requested types of agricultural products and natural foodstuffs. Modeling of {sup 137}Cs downward migration in soils is, ...

Effects of chronic treatment with honokiol in spontaneously hypertensive rats.

Astrocyte dysfunction is implicated in course of various age-related neurodegenerative diseases. Chronic injection of D-galactose can cause a progressive deterioration in learning and memory capacity and serve as an animal model of aging. To investigate the involvement of astrocytes in this model, oxidative stress biomarkers, biochemical and pathological changes of astrocytes were examined in the hippocampus of the rats with six weeks of D-galactose injection. D-galactose-injected rats displayed impaired antioxidant systems, an increase in nitric oxide levels, and a decrease in reduced glutathione levels. Consistently, western blotting and immunostaining of glial fibrillary acidic protein showed extensive activation of astrocytes. Double-immunofluorescent staining further showed activated astrocytes highly expressed inducible nitric oxide synthase. Electron microscopy demonstrated the degeneration of astrocytes, especially in the aggregated area of synapse and ...

Computed tomography and magnetic resonance imaging of acquired abnormalities of the inner ear and cerebello-pontine angle

The present study was performed to evaluate the antihypertensive effects of honokiol in vivo in spontaneously hypertensive rats (SHR). The effects of honokiol were investigated by determination of the blood pressure, vascular reactivity, oxidative parameters, and histologic change in the aorta. Long-term administration of honokiol (400 mg/kg/d) to SHR decreased systolic blood pressure significantly. Honokiol (200, 400 mg/kg/d) enhanced the aortic relaxation in response to acetylcholine after 49-d treatment, but had no significant effects on the relaxation to sodium nitroprusside. The oral administration of honokiol significantly increased the plasma level of NO(2(-))/NO(3(-)), but decreased the level of malondialdehyde in liver of SHR compared with the control vehicle. In addition, SHR administered honokiol showed significant reductions in the elastin bands and media thickness in the aorta. These results suggest that chronic treatment with honokiol exerts an ...

A preliminary study of a cartoon measure for children's reactions to chronic trauma.

CT and MRI of acquired abnormalities of the inner ear and cerebello-pontine angle present themselves with very typical findings. The imaging should be adapted to the pathology looked for and either CT or MRI should be used alone or in combination.CT, especially high resolution CT (HRCT), provides an excellent bone contrast, while MRI has a much superior soft tissue contrast. Acute inflammatory changes of the inner ear are solely depicted by contrast-enhanced MRI. HRCT excellently depicts osseous changes of the inner ear and cerebellopontine angle such as chronic ossifying labyrinthitis occurring after acute labyrinthitis, otosclerotic or traumatic changes. Tumorous changes not yielding to bony changes are best delineated by MRI. Posttraumatic hemorrhage and chronic fibrotic changes within the labyrinth are depicted by MRI, only. In conclusion HRCT and MRI are excellent methods to delineate acquired abnormalities of the inner ear and ...

A critical review of behavioural treatments for chronic benign pain other than headache.

Preliminary psychometric properties of a new instrument, Angie/Andy Cartoon Trauma Scales (ACTS), are presented. Angie/Andy features a cartoon-based methodology, measuring trauma-related sequelae of prolonged, repeated abuse. A sample of 208 children comprised intrafamilial trauma, extrafamilial trauma, combined trauma, and nontrauma groups. Angie/Andy demonstrated high internal consistency, with coefficient alphas from 0.70 to 0.95. The three trauma groups scored significantly higher than the nontrauma group on all scales (p's < 0.0001). Generally, the most severely traumatized group scored significantly higher than the less severely traumatized groups. The number of types of violence exposures correlated with Angie/Andy scores from 0.55 to 0.74. The frequency and severity of trauma exposure correlated with Angie/Andy scores from 0.44 to 0.56. The Angie/Andy parent version correlated with a standardized parent scale from 0.71 to 0.81. Parent/child agreement was significant. ...

The language of pain: affective descriptors of pain are a better predictor of psychological disturbance than pattern of sensory and affective descriptors.

Studies of the effectiveness of operant, relaxation, cognitive, and multimodal behavioural approaches to the treatment of chronic benign pain other than headache were evaluated. In general, the quality of the studies was poor, and most investigations lacked appropriate and adequate control conditions, outcome measures, and/or follow-ups. While outcome reports for all four behavioural treatments have been mainly positive, few data were found which conclusively demonstrate that any of the approaches are effective or that they are the treatment of choice. The data do, however, imply that behavioural approaches may help patients lead more normal and productive lives. Specifically, the literature suggests that: (1) the operant method leads to increased activity levels and decreased pain and drug intake, (2) the relaxation approach results in decreased EMG levels and some pain reductions, (3) the cognitive techniques are speculative at this time, and (4) the multimodal ...

The influence of multiple photoperiods and pinealectomy on gonads, pelage and body weight in male meadow voles, Microtus pennsylvanicus.

The language used by chronic benign pain patients to characterize their pain complaint was analyzed to determine the best predictor of psychiatric disturbance. Using the 78 adjectives provided by the McGill Pain Questionnaire, the number of affective descriptors used was the best predictor of psychiatric disturbance. Addition of sensory descriptors either to augment the total number of descriptors used (magnitude) or as a pattern of sensory greater than affective or sensory less than affective failed to increase predictive strength.

Role of nuclear medicine bone scans in evaluating pain in athletic injuries

1. Chronic exposure of male Microtus pennsylvanicus to photoperiods with 8, 10 and 12 hr of light per day results in gonadal regression, molt to winter pelage and significant reductions in body weight and food consumption relative to voles kept on photoperiods with 13 and 14 hr of light per day. 2. A precise critical daylength is observed in this species as exposure to photoperiods with 12 or fewer hours of light per day results in complete gonadal involution, seasonal molt and loss of body weight. 3. Pinealectomy abolishes all short-photoperiod induced responses in this species. PMID:2573458

Reciprocal regulation of the neural and innate immune systems

The utilization of nuclear medicine bone scanning examinations early in the diagnostic process allows physicians to render prompt and correct treatment in urgent or difficult athletic cases. Bone scanning should be performed for athletic injuries whenever (1) x-rays are normal but bone or joint pain persists; (2) x-rays are positive but it cannot be determined if the findings are acute or chronic; (3) soft-tissue injuries present and x-rays are not useful; and (4) bone pain or joint impairment present without a history of trauma.89 references.

Innate immune responses are regulated by microorganisms and cell death, as well as by a third class of stress signal from the nervous and endocrine systems. The innate immune system also feeds back, through the production of cytokines, to regulate the function of the central nervous system (CNS), and this has effects on behaviour. These signals provide an extrinsic regulatory circuit that links physiological, social and environmental conditions, as perceived by the CNS, with transcriptional 'decision-making' in leukocytes. CNS-mediated regulation of innate immune responses optimizes total organism fitness and provides new opportunities for therapeutic control of chronic infectious, inflammatory and neuropsychiatric diseases.

Recent advances in pharmacotherapy for dyspnea in COPD

British Library Electronic Table of Contents (United Kingdom)

Dyspnea is the most distressing symptom experienced by those suffering from advanced stages of chronic obstructive pulmonary disease (COPD). Activity-related dyspnea in COPD is multifactorial but is associated with increased central neural drive, impaired dynamic respiratory mechanics and abnormal respiratory muscle function. Each of these components can potentially be targeted for pharmacotherapy. Recent advances in the pharmacotherapy of COPD include the development of new long-acting bronchodilators which, when combined, provide sustained improvements in dyspnea. Additionally, novel applications of older therapies such as opiates, furosemide, helium-oxygen, and statins show early promise as dyspnea-relieving interventions in COPD. Effective pharmacological manipulation of the affective ...

Neuroinflammation and brain infections: Historical context and current perspectives

British Library Electronic Table of Contents (United Kingdom)

An overview of current concepts on neuroinflammation and on the dialogue between neurons and non-neuronal cells in three important infections of the central nervous systems (rabies, cerebral malaria, and human African trypanosomiasis or sleeping sickness) is here presented. Large numbers of cases affected by these diseases are currently reported. In the context of an issue dedicated to Camillo Golgi, historical notes on seminal discoveries on these diseases are also presented. Neuroinflammation is currently closely associated with pathogenetic mechanisms of chronic neurodegenerative diseases. Neuroinflammatory signaling in brain infections is instead relatively neglected in the neuroscience community, despite the fact that the above infections provide paradigmatic examples of alterations o...

Improvement of muscle strenght independently of analgesic effect following spinal cord stimulation. A case report.

Foraminal stenosis complicating retained broken epidural needle tip -A case report-.

Spinal cord stimulation (SCS) is frequently used for relief of chronic benign pain resistant to conservative therapies. Clinical practice suggests, at least in patients with failed back surgery syndrome (FBSS), the possibility that SCS significantly improves motor performances. We present here the case of a 41-years-old female patient with FBSS, who showed a clear improvement in muscle strength after SCS, persisting at 6-months follow-up. We speculate that the electrical stimulation of posterior columns could potentiate the caudal, segmental spinal reflexes resulting in a facilitation of motoneurons activation. PMID:16175150

Cellular Sources of Transforming Growth Factor-? Isoforms in Early and Chronic Radiation Enteropathy

Lumbar epidural anesthesia is useful in a variety of chronic benign pain syndromes, including lumbar radiculopathy, low back pain syndrome, spinal stenosis, and vertebral compression fractures. Given the increased number of epidural nerve blocks being performed, some have reported unexplained complications of a transient or permanent nature and with varying degrees of severity. However, no case has been reported of a broken epidural needle tip retained in the lumbar facet joint area. This represents the first reported case presentation of foraminal stenosis developing in a patient after a retained epidural needle tip. PMID:21286465

Cadmium and endrin toxicity to fish in waters containing mineral fibers

The three mammalian transforming growth factor (TGF)-? isoforms (TGF-?1, TGF-?2, and TGF-?3) differ in their putative roles in radiation-induced fibrosis in intestine and other organs. Furthermore, tissue specificity of TGF-? action may result from temporal or spatial changes in production and/or activation. The present study examined shifts in the cell types expressing TGF-? mRNA relative to TGF-? immunoreactivity and histopathological injury during radiation enteropathy development. A 4-cm loop of rat small intestine was locally exposed to 0, 12, or 21-Gy single doses of x-irradiation. Sham-irradiated and irradiated intestine were procured 2 and 26 weeks after irradiation. Cells expressing the TGF-?1, TGF-?2, or TGF-?3 transcripts were identified by in situ hybridization with digoxigenin-labeled riboprobes. Intestinal wall TGF-? immunoreactivity was measured using computerized image analysis, and structural radiation injury was assessed by quantitative histopathology. Normal ...

Acquired cystic kidney disease

Taconite tailings and their component asbestiform minerals in Lake Superior water had no demonstrable effect on the chronic toxicity of cadmium to the flagfish, Jordanella floridae. Maximum acceptable toxicant concentrations determined in life cycle tests, where effects on survival, growth, reproduction, and bioconcentration were used as endpoints, were between 3.3 to 7.4, 3.0 to 6.5, and 3.4 to 7.3 micrograms cadmium/liter at 0.004, 0.08, and 0.95 mg/liter taconite tailings concentrations, respectively.

A research agenda to examine the efficacy and relevance of the Transtheoretical Model for physical activity behavior

Acquired cystic kidney disease (ACKD), also known as acquired renal cystic disease (ARCD,) occurs in patients who are on dialysis for end-stage renal disease. It is generally accepted that ACKD develops as a consequence of sustained uremia and can first manifest even before dialysis is initiated while the patient is still in chronic renal failure. The role of immune suppression, particularly in transplant recipients, in the development of ACKD, is still under investigation. The prevalence of ACKD is directly related to the duration of dialysis and the risk of cancer is directly related to the presence of cysts. Herein we review the current understanding of the pathophysiology and imaging implications of ACKD. (orig.)

Regular physical activity (PA) decreases the risk of several chronic diseases including some cancers, type II diabetes, obesity, and cardiovascular disease; however, the majority of US adults are not meeting the recommended levels to experience these benefits. To address this public health concern, the underlying mechanisms for behavior change need to be understood, translated and disseminated into appropriately tailored interventions. The Transtheoretical Model (TTM) provides a framework for both the conceptualization and the measurement of behavior change, as well as facilitating promotion strategies that are individualized and easily adapted. The purpose of this manuscript is to present the constructs of the TTM as they relate to PA behavior change. We begin with a brief synopsis of rec...

A Patient-Centric, Provider-Assisted Diabetes Telehealth Self-management Intervention for Urban Minorities

Relationship between acute ozone responsiveness and chronic loss of lung function in residents of a high-ozone community

This article describes the design and implementation of an online diabetes self-management intervention for a sample of inner-city African Americans with diabetes. Study participants were randomly assigned to the treatment (26) and control (21) conditions. The results indicate that treatment group participants were more likely to achieve positive outcomes in terms of lowered hemoglobin A1c and body mass index measurements than were control group members. These findings support the development of telehealth interventions to promote effective chronic disease management in medically underserved communities.

Metallothionein (MT) response after chronic palladium exposure in the zebra mussel, Dreissena polymorpha

The authors hypothesized that acute respiratory responsiveness to ozone predicts chronic lung injury from repeated exposure to ozone-containing air pollution. They tested this hypothesis in 164 middle-aged nonsmoking residents of an ozone-polluted community who underwent lung-function measurements during 1986 and 1987 (i.e., time 3). The time-3 study was a follow up of more comprehensive studies conducted in 1977--1978 (time 1) and in 1982--1983 (time 2). In contrast to the apparent rapid (i.e., {approx} 60 ml/y) decline in lung-function measurements between times 1 and 2, their subjects showed little change in forced vital capacity (FVC) or forced expired volume in 1 s (FEV{sub 1.0}) between times 2 and 3, and they experienced a normal decline between times 1 and 3. A subgroup (n = 45) underwent 2-h laboratory ozone exposures to 0.4 ppm ozone, accompanied by intermittent exercise, and they experienced mild acute reductions in FEV{sub 1.0} and FVC, but there was ...

Contribution of pulmonary emphysema to functional impairment in patients with severe chronic obstructive pulmonary disease. A high-resolution CT study

The effects of different exposure concentrations of palladium (Pd) on relative metallothionein (MT) response and bioaccumulation were investigated in zebra mussels (Dreissena polymorpha). The mussels were exposed to 0.05, 5, 50, and 500 ?g/L Pd2+ for 10 weeks under controlled temperature and fasting conditions. Relative MT contents were assessed by a modified Ag-saturation method, which allows to discriminate between MT bound to Pd (Pd-MT) and MT bound to unidentified metals (Ag-MT). Determination of metal contents resulted from atomic absorption spectrometry following a microwave digestion. For unexposed mussels and mussels exposed to 0.05 ?g/L Pd no metal accumulation could be detected. All other exposure concentrations resulted in detectable Pd accumulation in mussels with final tissue concentrations of 96 ?g/g (500 ?g/L), 45 ?g/g (50 ?g/L), and 9 ?g/g (5 ?g/L). Compared with initial levels Pd-MT concentrations at the end of the exposure period were 600 (500 ?g/L), 160 (50 ?g/L), ...

Usefulness of multifunctional gastrointestinal coil catheter for colorectal stent placement

The purpose of the paper is to investigate whether high-resolution CT (HRCT) can detect the subjects with massive emphysematous destruction in a group of patients with severe chronic obstructive pulmonary disease (COPD) and therefor be of help in selecting the candidates to surgical lung volume reduction. Have been examined 40 former smokers with severe COPD (FEV_1#<=#40% of the predicted value, with no major improvement after inhalation of bronchodilators). The emphysema extent score was significantly correlated with the hematocrit value and Tiffeneau index (p<2) in all the 40 patients. The severity of bronchial obstruction was the same in bronchitis and dyspnoeic patients. The subject with chronic bronchitis had milder emphysema (mean extent 35% versus 47% in the dyspnoeic subjects) and a higher frequency of bronchial involvement. A decrease in FEV_1 was significantly correlated with emphysema extent (p<1) in dyspnoeic, but not in ...

Transforming growth factor-b induces nerve growth factor expression in pancreatic stellate cells by activation of the ALK-5 pathway

The purpose of this study was to evaluate the usefulness of a multifunctional gastrointestinal coil catheter for stent placement in 98 patients with colorectal strictures. The catheter was used in 98 consecutive patients for stent placement in the rectum (n = 24), recto-sigmoid (n = 13), sigmoid (n = 38), descending (n = 6), transverse (n = 11), splenic flexure (n = 3), hepatic flexure (n = 2), and ascending (n = 1) colon. The catheter was made of a stainless steel coil (1.3 mm in inner diameter), a 0.4-mm nitinol wire, a polyolefin tube, and a hemostasis valve. Usefulness of the catheter was evaluated depending on whether the catheter could pass a stricture over a guide wire and whether measurement of the stricture length was possible. The passage of the catheter over a guide wire beyond the stricture was technically successful and well tolerated in 93 (94.9%) of 98 patients. In the failed five patients, it was not possible to negotiate the guide wire due to ...

Nerve growth factor (NGF), a survival factor for neurons enforces pain by sensitizing nociceptors. Also in the pancreas, NGF was associated with pain and it can stimulate the proliferation of pancreatic cancer cells. Hepatic stellate cells (HSC) respond to NGF with apoptosis. Transforming growth factor (TGF)-b, one of the strongest pro-fibrogenic activators of pancreatic stellate cells (PSC) induced NGF and its two receptors in an immortalized human cell line (ihPSC) and primary rat PSC (prPSC) as determined by RT-PCR, western blot, and immunofluorescence. In contrast to HSC, PSC expressed both NGF receptors, although p75NTR expression was weak in prPSC. In contrast to ihPSC TGF-b activated both Smad signaling cascades in prPSC. NGF secretion was diminished by the activin-like kinase (ALK)...

Transcription Factor IIA t Is Associated with Undifferentiated Cells and Its Gene Expression Is Repressed in Primary Neurons at the Chromatin Level In Vivo

British Library Electronic Table of Contents (United Kingdom)

The levels of General Transcription Factor (TF) IIA were examined during mammalian brain development and in rat embryo fibroblasts and transformed cell lines. The large TFIIA subunit paralogues ab and t are largely produced in unsynchronized cell lines, yet only TFIIA ab is observed in a number of differentiated tissue extracts. Steady-state protein levels of the TFIIA t, ab, and g subunits were significantly reduced when human embryonal (ec) and hepatic carcinoma cell lines were stimulated to differentiate with either all-trans-retinoic acid (ATRA) or sodium butyrate. ATRA-treated NT2-ec cells required replating to induce a neuronal phenotype and loss of detectable TFIIA t and g proteins. High levels of TFIIA t, ab, and g and Sp factors were identified in extracts from human fetal and rat...

Transcatheter internal radiotherapy of hepatoma using radioactive iodized oil (I-131 Lipiodol)

Tissue factor contributes to neutrophil CD11b expression in alpha-naphthylisothiocyanate-treated mice

The lymphographic agent Lipiodol (iodized oil) has been found to localize and remain in tumor vessels. Based on this finding, we attempted transcatheter internal radiotherapy by radioactive iodized oil (I-131 tagged Lipiodol) prepared by isotopic exchange reaction. Transcatheter internal radiotherapy (TCIR) was attempted in twelve patients with inoperable hepatoma by infusing a therapeutic dose of I-131 Lipiodol (7.6 approx. 28.3 mCi/2.0 approx. 5.0 ml) via the hepatic artery. Serial changes of serum alpha-fetoprotein (AFP) levels and in the size of tumor on computed tomography (CT) were estimated to evaluate the therapeutic effect. Serum AFP levels decreased in 9 patients with initial elevated levels of serum AFP, although they were again elevated in three of them within four weeks. More than 50 % decrease in tumor size was observed in 6 patients (50 %). There were no serious complications. This preliminary results suggest that TCIR with I-131 Lipiodol will be one ...

Cholestatic liver injury induced by alpha-naphthylisothiocyanate (ANIT) is provoked by injury to intrahepatic bile ducts and the progression of hepatic necrosis requires the procoagulant protein tissue factor (TF) and extrahepatic cells including neutrophils. Recent studies have shown that myeloid cell TF contributes to neutrophil activation. We tested the hypothesis that myeloid cell TF contributes to neutrophil activation in ANIT-treated mice. TF activity in liver homogenates increased significantly in TF^f^l^o^x^/^f^l^o^x mice treated with ANIT, but not in TF^f^l^o^x^/^f^l^o^x/LysMCre mice (TFD^M^y^e^l^o^i^d mice), which have reduced TF expression in monocytes/macrophages and neutrophils. Myeloid cell-specific TF deficiency did not alter expression of the chemokines KC or MIP-2 but redu...

The combination therapy with hepatic arterial infusion chemotherapy and radiation therapy for unresected intrahepatic cholangiocarcinoma

Radionuclide liver and bone scanning in the evaluation of patients with endometrial carcinoma

The outcome was retrospectively examined and prognostic factors were discussed for arterial chemo-infusion therapy (ACT) through an implanted reservoir system and radiation therapy (RT) in patients with unresectable intrahepatic cholangiocarcinoma (CCC). ACT plus RT were conducted to 25 patients (mean age 61.7 y, M/F 12/13, stage III-IVB) during 10 years from 1996 to 2005 with various regimens of cisplatin (CDDP), 5- fluorouracil (FU), epirubicin (FARM), mitomycin C (MMC) plus 39-50 Gy of radiation in a fractionated manner partly involving internal RT (2 cases, 15 Gy) and RT for metastatic bone (1, 25 Gy). The survival rates at 1, 2 and 3 years after ACT+RT were respectively 52.5, 43.7 and 28.1%; total efficacy (PR) was 36% (9/25) at 6 months; and significantly good prognostic factors were found to be female and absence of metastasis remote and/or lymphatic around artery. Authors concluded that ACT+RT was a meaningful treatment for highly advanced non-respectable CCC and that ...

Macromodular splenic tuberculosis in a medically-treated AIDS patient: diagnosis and management by CT

Staging bone scans or skeletal surveys were obtained of 97 patients with endometrial carcinoma. Of the 77 patients with Stage I or II disease, no metastases were identified at staging. Three patients in the entire series demonstrated bony metastases; all of these metastases were detectable by radionuclide bone scan and radiographic bone survey. Eighty-nine patients were examined with radionuclide liver/spleen scanning at the time of staging. Four of the 89 initial scans were interpreted as demonstrating hepatocellular disease, and all four patients had abnormal liver function studies. Only one patient demonstrated a possible hepatic metastasis at initial diagnosis. This patient also had abnormal liver function studies. Based on these results, bone surveys and radionuclide bone scans are not indicated as screening procedures in endometrial carcinoma. It is suggested that screening for liver metastases in patients with endometrial carcinoma is not warranted in ...

Lipiodol-CT findings of hepatocellular carcinoma: Correlation with lipiodol accumulation pattern and serum AFP

We used computerized tomography (CT) in the study of eight patients with macronodular splenic tuberculosis prior to the microbiological diagnosis. These patients underwent additional CT controls during and after tuberculostatic therapy. All the patients studed presented the acquired immunodeficiency syndrome (AIDS). Splenomegaly and numerosous round, hypodense lesions that showed no contrast uptake were found in all the subjects. Only three patients presented evidence of tuberculosis in plain radiography and/or chest X-ray. Two patients presented abdominal lymph nodes. None of them showed evidence of hepatic lesions or ascites. follow-up CT scans revealed a progressive reduction of the lesions, which eventually disappeared completely, and splenomegaly was considerably reduced. Anthough it is uncommon, we should suspect splenic involvement in tuberculosis if the clinical and radiological contexts are appropriate. CT provides excellent monitoring of the efficacy of ...

Hepatobiliary scintigraphy in current pediatric practice

Early diagnosis of hepatocellular carcinoma (hepatoma) along with surgical resection is the most appropriate therapeutic modality. For this purpose, there have been many reports concerning the diagnostic value of Lipiodol-CT scan. The authors selected 45 patients with hepatoma during the period of Feb.1986 to Jan. 1988 who received a conventional CT scan, hepatic angiography and a Lipiodol-CT scan. The results were as follows: 1. There was no statistical significant between serum AFP level and mass size, morphology and amount of necrosis. 2. Tumor necrosis was observed in a single massive and multinodular type when the tumor size exceeded 5 cm. 3. Pattern II on Lipiodol-CT, homogenous accumulation of Lipiodol except for the area of inner necrosis, was most frequently demonstrated, which means that a tumor mass with hypervascularity and increased blood flow will attract Lipiodol better. 4. Lipiodol-CT was superior to conventional CT in detecting small, daughter ...

Evolution of virtual CT laparoscopy for preoperative imaging in laparoscopic cholecystectomy

Hepatobiliary scintigraphy is the only non-invasive technique providing real-time assessment of hepatocytes function and bile progression from the liver to the intestine; for this reason it is of great importance in the study of jaundice and many other disorders of the liver and the biliary tract in children. Ultrasonography is the initial method of evaluating the intra- and extrahepatic bile ducts dilatation: the differential diagnosis between biliary atresia and neonatal hepatitis cannot however be done without hepatobiliary scintigraphy. Cystic fibrosis patients also require hepatobiliary scintigraphy; liver and biliary tract disease can really occur independently of the underlying disease severity and the presence of steatorrhoea. Hepatobiliary imaging in children who have undergone liver transplantation is of major importance; it can assess vascularity, parenchymal function biliary drainage, possible presence of a bile leak and obstruction; it has very good ...

Effect of butylated hydroxytoluene pretreatment on the excretion, tissue distribution and DNA binding of (/sup 14/C)aflatoxin B1 in the rat

The purpose of this study was to determine the feasibility of virtual endoscopy, named as ''virtual CT laparoscopy'', in the hepatobiliary system prior to laparoscopic cholecystectomy. We applied this technique to 28 patients suspected of having biliary disease. These images were compared and analyzed qualitatively based on visualization of the structures critical to operative cholangiography and surgical findings. Twenty-four patients, who underwent laparoscopic cholecystectomy, were evaluated as follows: the common bile duct and the hepatic duct were adequately visualized in 23 (96%) of the 24 patients, the cystic duct in 21 (88%), the gallbladder opacification in 20 (83%), the liver inferior surface in 20 (83%). Four patients had anatomic variations detected virtual CT laparoscopy and were proven by operative cholangiography and surgical findings. We emphasize that our new technique may contribute to the laparoscopy during ...

Diagnosis for the cancer extension of cholangiocarcinoma. The current status

The effect of butylated hydroxytoluene (BHT) pretreatment (0.5% in the diet for 10 days) on the excretion, tissue distribution and DNA binding of orally administered (/sup 14/C)aflatoxin B1 (AFB1) was determined in male Fischer F344 rats. The amount of radioactivity excreted in the urine and feces by 24 hr was higher in BHT-treated rats than in controls. Treatment with BHT enhanced the excretion of water-soluble metabolites in the urine and in the large intestines plus feces at the earlier sampling times. The amount of radioactivity bound to hepatic nuclear DNA was six times less in the BHT-pretreated rats than in controls 6 hr after administration of the isotope. The half-lives of (/sup 14/C)DNA in the rat liver were 30 and 46 hr for control and BHT-pretreated rats, respectively. These results indicate that BHT pretreatment may protect the animal from the carcinogenic effects of AFB1 by enhancing the detoxification and excretion of the mycotoxin.

Clinical evaluation of serum ferritin to iron ratio in malignant diseases

Described is the diagnosis for the cancer extension of cholangiocarcinoma by various imaging techniques and processes to support the current surgical procedure based on preoperative biliary drainage. The cancer tends to locally extend horizontally and/or vertically and its diagnosis is important for surgical indication. For the indication, multi-detector raw CT (MDCT) and MR cholangio-pancreatography (MRCP) are useful and particularly, the former can give multi-phase (arterial, portal and delayed) images to reconstruct multiplanar (MPR) and CT angiographic 3D images, which have made the previous invasive examinations like angiography and percutaneous transportal contrasting unnecessary. MDCT and MRCP can almost complete the diagnosis of the extension. The operative procedure is decided dependently on the site of the lesion, and of which diagnosis, whether it is hepatic hilar/on upper bile duct or middle/lower ductal, is different. MDCT-MPR and MRCP are virtually ...

Cholangiocarcinoma associated with recurrent pyogenic cholangitis: sonographic and CT findings

Serum ferritin levels were measured in 72 normal subjects and in 214 cases with various diseases by an immunoradiometric assay. In normal subjects, the serum ferritin levels were 27-230 ng/ml. Elevated serum ferritins were observed in most cases with iron excess and acute hepatitis. Markedly elevated levels were found in the majority of cases with acute leukemia, malignant lymphoma, hepatoma, and pancreatic cancer. High ferritin levels were also found in other malignant diseases. However, the range overlapped broadly with that of nonmalignant diseases. The serum ferritin correlated significantly with serum iron in normals and in those with iron deficiency anemia. In most nonmalignant cases, the serum ferritin and iron levels distributed on a regression line obtained from levels in normals and those with iron deficiency anemia. However, 92% of the malignant cases showed a serum ferritin to iron ratio higher than that of normal subjects. The estimation of the serum ...

CT diagnosis of intrahepatic cholangiocarcinoma

Cholangiocarcinoma may be associated with recurrent pyogenic cholangitis as a complication of longstanding proliferative cholangitis in the presence of intrahepatic stones. Sonographic and CT findings of six patients with cholangiocarcinoma of the liver associated with recurrent pyogenic cholangitis are presented. The cases were among 128 patients who underwent partial resection of the liver because of recurrent pyogenic cholangitis and its complication. On sonogram the mass was depicted in four patients as an ill-defined heterogenously echogenic mass and in one patient as a bulging contour; in the remaining one case the mass was not detected. There were small or large, shadowing or non shadowing stones within the tumor in five cases. In one case, the stone was in the duct proximal to the tumor. On CT scans of four patients, the tumors were depicted as an ill-defined, irregular low attenuation masses with variable contrast enhancement, the periphery being more enhanced. The stones were ...

Argentinian doctors accused of spreading AIDS.

Purpose: To evaluate contrast-enhanced CT scan in the diagnosis of intrahepatic cholangiocarcinoma by correlating the CT appearance with pathologic specimens. Materials and methods: Twenty-eight patients with pathologically proven intrahepatic cholangiocarcinoma were examined. Unenhanced abdominal CT study were performed in 28 patients; conventional contrast-enhanced CT in 27 patients. Enhanced CT scan including fast injection, fast scan and delayed scan at the largest section of the lesion was done in 7 patients. Contiguous 10 mm CT scans of the surgical specimens were also obtained in 8 patients. The preoperative and specimen CT scans in these 8 patients were compared with the corresponding pathological sections. A total of 103 areas of the pathological sections was compared with the CT appearances. Results: All lesions contained areas of delayed contrast enhancement and/or no enhancement on CT examinations. The areas of delayed contrast enhancement corresponded to areas of extensive ...

The provincial ministry of health has taken over a dialysis center in La Plata, Argentina, following the discovery that at least 20 of the clinic's 34 regular patients have been infected with the human immunodeficiency virus (HIV). Catheters of the clinic's dialysis machines were found to be contaminated with HIV. The 5 physicians associated with the Centro Modelo de Dialisis have been discharged for negligence. 20 of the regular patients also contracted hepatitis C. Argentinian law stipulates that filters for the same patient must be changed after 4 times and prohibits the use of the same vessel to administer medication to more than 1 patient. Testimony from nurses at the La Plata clinic revealed that filters were reused for several patients and basic sanitary procedures were not followed. In 1990, 33 kidney disease patients at a dialysis center in Cordoba became infected with HIV and it was discovered that filters had been used up to 8 times for different ...

Wheat grain quality under enhanced tropospheric CO{sub 2} and O{sub 3} concentrations

Purpose : To evaluate whether the early pulmonary irradiation can prevent or decrease the pulmonary damage and contribute to improve ultimate survival in paraquat lung. Materials and Methods : From Jun. 1987 to Aug. 1993, thirty patients with paraquat poisoning were evaluated. Fourteen of these patients were received pulmonary irradiation(RT). All of the patients ere managed with aggressive supportive treatment such as gastric lavage, forced diuresis, antioxidant agents and antifibrosis agents. Ingested amounts of paraquat were estimated into three groups(A: minimal < about 5cc, B: mouthful 5-50 cc, C: Large > 50cc). Pulmonary irradiation was started within 24 hours after admission(from day 1 to day 11 after ingestion of paraquat). Both whole lungs were irradiated with AP/PA parallel opposing fields using C0-60 teletherapy machine. A total of 10Gy(2Gy/fr. X 5 days)was delivered without correction of lung density. Results : In group A, all patients were alive regardless of ...

The health impact of pemphigus vulgaris and pemphigus foliaceus assessed using the Medical Outcomes Study 36-item short form health survey questionnaire

It is expected that the progressive increase of tropospheric trace gases such as CO{sub 2} and O{sub 3} will have a significant impact on agricultural production. The single and combined effects of CO{sub 2} enrichment and tropospheric O{sub 3} on grain quality characteristics in soft red winter wheat (Triticum aestivum L.) were examined in field studies using 3 m in diam. open-top chambers. Wheat cultivars {open_quotes}Massey{close_quotes} (1991) and {open_quotes}Saluda{close_quotes} (1992) were exposed to two CO{sub 2} concentrations (350 vs. 500 {mu}mol CO{sub 2} mol{sup {minus}1}; 12 h d{sup {minus}1}) in combination with two O{sub 3} regimes (charcoal-filtered air vs. ambient air + 40 {plus_minus} 20 nmol O{sub 3} mol{sup {minus}1}, 7 h d{sup {minus}1}; Monday to Friday) from late March until maturity in June. Grain quality characteristics investigated included: test weight, milling and baking quality, flour yield, protein content, softness equivalent, alkaline water retention ...

Summary Background Pemphigus vulgaris and pemphigus foliaceus are rare, potentially life-threatening, autoimmune disorders characterized by antibodies to epidermal adhesion molecules. Clinical characteristics are painful chronic erosions of mucous membranes and of the skin. There are only few published studies on the impact of the disease on the health status (HS) of patients with these conditions. Objectives To assess the impact of disease on the HS of patients with pemphigus. Methods Fifty-eight patients enrolled at the Bullous Skin Diseases Unit of IDI-IRCCS in the period January-June 2006 were assessed for their HS using the Medical Outcomes Study 36-item short form health survey (SF-36) questionnaire and for anxiety and depression using the Institute for Personality and Ability Testin...

Short-term synaptic plasticity in the auditory brain stem by using in-vivo-like stimulation parameters

British Library Electronic Table of Contents (United Kingdom)

Reduced systems such as brain slices offer a powerful approach to study the physiology of auditory neurons in great detail. However, when studying auditory nuclei in reduced systems such as brain slices, especially highly active auditory brain stem nuclei, one has to be aware that the unphysiological lack of activity in the reduced system compared to the in-vivo situation has a number of important effects on the neurons under investigation, and thus on the data that are measured. Most importantly, the lack of chronic activity in the slice preparation has important effects on the properties of short-term plasticity of the synapses. The main purpose of this article is to discuss how spontaneous activity in auditory neurons, or the lack thereof, can affect the data measured.

Radon concentration measurements in bituminous coal mines

Penile rehabilitation therapy with PDE-V inhibitors following radical prostatectomy: proceed with caution.

Radon measurements were carried out in Kozlu, Karadon and Uzulmez underground coal mines of Zonguldak bituminous coal basin in Turkey. Passive-time integrating method, which is the most widely used technique for the measurement of radon concentration in air, was applied by using nuclear etched track detectors (CR-39) in the study area. The radon concentration measurements were performed on a total of 42 points in those three mines. The annual exposure, the annual effective dose and lifetime fatality risk, which are the important parameters for the health of workers, were estimated based on chronic occupational exposure to the radon gas, which is calculated using UNCEAR-2000 and ICRP-65 models. The radon concentrations at several coal production faces are higher than the action level of 1000 Bq m{sup -3}. It is suggested that the ventilation rates should be rearranged to reduce the radon concentration.

Nerve-Evoked Constriction of Rat Tail Veins Is Potentiated and Venous Diameter Is Reduced after Chronic Spinal Cord Transection

Penile rehabilitation therapy following radical prostatectomy is a much debated topic. Erectile dysfunction is still a significant contributor to postoperative morbidity following radical prostatectomy, despite meticulous nerve-sparing technique. Secondary smooth muscle changes in the penis have been identified as the underlying causes of penile atrophy, veno-occlusive dysfunction, and fibrosis. Initial observations that intracavernous injection therapies used on a regular basis postoperatively resulted in improvements in the return of spontaneous erectile function led to the development of penile rehabilitation protocols. Chronic dosing of PDE-V inhibitors is now commonly used by urologists after radical prostatectomy. Despite the current enthusiasm of penile rehabilitation therapy, current scientific evidence with clinical trials is still limited. PMID:19255627

Abstract Despite reduced sympathetic activity below the level of a spinal cord injury (SCI), venoconstriction during autonomic dysreflexia increases venous return to the heart. Here, contractions of isometrically mounted tail veins from rats with spinal transection at T4 performed 8???10 weeks earlier are compared with those from sham-operated rats. After SCI, lumen diameter was reduced by ?30% and the contractions evoked by electrical stimulation of the perivascular axons were larger than control. This augmentation of neurovascular transmission was not associated with enhanced sensitivity to ?-adrenoceptor agonists or to adenosine-5?-triphosphate (ATP) although contractions to depolarization with K+ were larger after SCI. The percentage reduction in nerve-evoked contraction after SCI prod...

Mucosal Inflammation in Spondylarthritides: Past, Present, and Future

British Library Electronic Table of Contents (United Kingdom)

Spondylarthritides (SpA) and inflammatory bowel disease (IBD) are idiopathic, chronic inflammatory disorders. Although they are very distinct and well-defined entities, there is clinical and genetic evidence supporting some degree of overlap between the pathogenesis of the two. Subclinical gut inflammation is present in up to two thirds of all SpA patients and can evolve into IBD. This subclinical gut inflammation has been shown to be strongly associated with joint inflammation, providing a clue for a common pathophysiologic background. Despite extensive research progress in the field over the past few years, many questions remain unanswered. In this paper, we focus on the clinical, genetic, and pathophysiologic overlap of SpA and IBD. Furthermore, we discuss some of the targets that may i...

High-Resolution Optical Coherence Tomography Findings in Solar Maculopathy and the Differential Diagnosis of Outer Retinal Holes

British Library Electronic Table of Contents (United Kingdom)

PurposeTo characterize the morphology of outer retinal holes caused by solar maculopathy, using spectral-domain optical coherence tomography (SD-OCT). DesignThis study is an observational case series. MethodsThe SD-OCT findings of 3 patients (6 eyes) with chronic solar maculopathy are presented. ResultsSD-OCT demonstrates a characteristic appearance of partial-thickness hole(s) in the outer retina at the fovea. In 3 of 6 eyes, there is 1 hole directly beneath the umbo. In the remaining 3 eyes, there are multifocal holes spread across the fovea. Holes in more restricted layers, as had been previously reported with time-domain OCT, were not seen. In addition, advanced visualization of SD-OCT data demonstrates a hyperreflective ring around the outer retinal hole. ConclusionsSD-OCT can be used...

Gallstones: choosing the right therapy despite vague clinical clues.

Exploration of the hypothalamic?pituitary?adrenal function as a tool to evaluate animal welfare

Therapeutic decisions are quite clear-cut for asymptomatic gallstone disease and acute cholecystitis. However, the appropriate therapeutic course for older patients with chronic cholecystitis may be less obvious. Watchful waiting may be reasonable for patients with mild and infrequent symptoms. For healthy patients, cholecystectomy is recommended if symptoms are becoming more frequent and severe. Laparoscopy may reduce the complication rate and be safely performed even in those with underlying medical illness. Oral dissolution therapy can be attempted for qualifying symptomatic patients who are at poor surgical risk or who refuse surgery. Shock wave lithotripsy and contact dissolution therapy show some promise but are currently experimental. PMID:8339941

Measuring HPA axis activity is the standard approach to the study of stress and welfare in farm animals. Although the reference technique is the use of blood plasma to measure glucocorticoid hormones (cortisol or corticosterone), several alternative methods such as the measurement of corticosteroids in saliva, urine or faeces have been developed to overcome the stress induced by blood sampling itself. In chronic stress situations, as is frequently the case in studies about farm animal welfare, hormonal secretions are usually unchanged but dynamic testing allows the demonstration of functional changes at several levels of the system, including the sensitization of the adrenal cortex to ACTH and the resistance of the axis to feedback inhibition by corticosteroids (dexamethasone suppression t...
