    Atrophic gastritis, is the main consequence of long-standing Helicobacter pylori infection, and is linked to the development of gastric cancer. The severity of atrophic gastritis is related to the lifetime risk of gastric cancer development, especially in terms of its degree and extent of mucosal damage. Therefore, it is important for clinicians to assess the severity of atrophic gastritis, interfere with the disease progress, and reverse gastric mucosal atrophy. In the article, we demonstrated some methods (conventional endoscopy, modern endoscopic technology and noninvasive methods) that may help assess the severity of atrophic gastritis and select the reasonable treatment protocols.

    Full Text Available Background/Aim. Hepcidin, an iron regulatory hormone, is increased in response to inflammation and some infections. We investigated the relationships among serum prohepcidin, iron status, Helicobacter pylori infection status, and the presence of gastric mucosal atrophy. Methods. Seventy subjects undergoing esophagogastroduodenoscopy underwent multiple gastric biopsies, and the possibility of H. pylori infection and the degree of endoscopic and histologic gastritis were investigated. In all subjects, serum prohepcidin and iron parameters were evaluated. Results. No correlations were observed between serum prohepcidin levels and the other markers of anemia, such as hemoglobin, serum iron, ferritin, and total iron binding capacity. Serum prohepcidin levels were not significantly different between the H. pylori-positive group and the H. pylori-negative group. Serum prohepcidin levels in atrophic gastritis patients were significantly lower than those in subjects without atrophic gastritis irrespective of H. pylori infection. Conclusion. Serum prohepcidin levels were not altered by H. pylori infection. Serum prohepcidin levels decrease in patients with atrophic gastritis, irrespective of H. pylori infection. It suggests that hepcidin may decrease due to gastric atrophy, a condition that causes a loss of hepcidin-producing parietal cells. Further investigations with a larger number of patients are necessary to substantiate this point.

    The objective of this study was to explore hair mercury level in association with chronic atrophic gastritis, a precancerous stage of gastric cancer (GC), and thus provide a brand new angle of view on the timely intervention of precancerous stage of GC. We recruited 149 healthy volunteers as controls and 152 patients suffering from chronic gastritis as cases. The controls denied upper gastrointestinal discomforts, and the cases were diagnosed as chronic superficial gastritis (n=68) or chronic atrophic gastritis (n=84). We utilized Mercury Automated Analyzer (NIC MA-3000) to detect hair mercury level of both healthy controls and cases of chronic gastritis. The statistic of measurement data was expressed as mean ± standard deviation, which was analyzed using Levene variance equality test and t test. Pearson correlation analysis was employed to determine associated factors affecting hair mercury levels, and multiple stepwise regression analysis was performed to deduce regression equations. Statistical significance is considered if p value is less than 0.05. The overall hair mercury level was 0.908949 ± 0.8844490 ng/g [mean ± standard deviation (SD)] in gastritis cases and 0.460198 ± 0.2712187 ng/g (mean±SD) in healthy controls; the former level was significantly higher than the latter one (p=0.000Pearson correlation analysis indicated that eating seafood was most correlated with hair mercury level and positively correlated in the healthy controls and that the severity of gastritis was most correlated with hair mercury level and positively correlated in the gastritis cases. Multiple stepwise regression analysis indicated that the regression equation of hair mercury level in controls could be expressed as 0.262 multiplied the value of eating seafood plus 0.434, the model that was statistically significant (p<0.01). Multiple stepwise regression analysis also indicated that the regression equation of hair mercury level in gastritis cases could be expressed as 0

Method: Observe the effects of acupuncture and moxibustion at the points of Zusanli, Zhongwan and Tianshu on gastric mucosa in model rats with chronic atrophic gastritis. Results:Acupuncture and moxibustion can increase the contents of PGE2α, PGF2α and cAMP, and decrease the content of cGMP in the tissue of gastric mucosa. Conclusion: Acupuncture and moxibustion shows cytoprotection on gastric mucosa, so it is an effective method for treating chronic atrophic gastritis.

  8. Comparative proteomics analysis of chronic atrophic gastritis: changes of protein expression in chronic atrophic gastritis with out Helicobacter pylori infection

    International Nuclear Information System (INIS)

    Chronic atrophic gastritis (CAG) is a very common gastritis and one of the major precursor lesions of gastric cancer, one of the most common cancers worldwide. The molecular mechanism underlying CAG is unclear, but its elucidation is essential for the prevention and early detection of gastric cancer and appropriate intervention. A combination of two-dimensional gel electrophoresis and mass spectrometry was used in the present study to analyze the differentially expressed proteins. Samples from 21 patients (9 females and 12 males; mean age: 61.8 years) were used. We identified 18 differentially expressed proteins in CAG compared with matched normal mucosa. Eight proteins were up-regulated and 10 down-regulated in CAG when compared with the same amounts of proteins in individually matched normal gastric mucosa. Two novel proteins, proteasome activator subunit 1 (PSME1), which was down-regulated in CAG, and ribosomal protein S12 (RPS12), which was up-regulated in CAG, were further investigated. Their expression was validated by Western blot and RT-PCR in 15 CAG samples matched with normal mucosa. The expression level of RPS12 was significantly higher in CAG than in matched normal gastric mucosa (P < 0.05). In contrast, the expression level of PSME1 in CAG was significantly lower than in matched normal gastric mucosa (P < 0.05). This study clearly demonstrated that there are some changes in protein expression between CAG and normal mucosa. In these changes, down-regulation of PSME1 and up-regulation of RPS12 could be involved in the development of CAG. Thus, the differentially expressed proteins might play important roles in CAG as functional molecules

    Full Text Available The clinical pathological characteristics of 3969 adult patients with chronic atrophic gastritis were retrospectively studied. The positivity of intestinal metaplasia and dysplasia in atrophic gastric specimens increased with age; however, H. pylori positivity and inflammatory activity decreased significantly with increased age. H. pylori infection was present in 21.01% of chronic atrophic gastritis patients, and 92.33% of the subjects with H. pylori infection were found to have simultaneous inflammatory activity. The intestinal metaplasia and dysplasia positivity markedly increased as the degree of gastric atrophy increased. In conclusion, the incidence of H. pylori infection decreased with age and correlated significantly with inflammatory activity in atrophic gastritis patients. The intestinal metaplasia and dysplasia positivity notably increased as the degree of gastric atrophy increased. Large population-based prospective studies are needed to better understand the progression of CAG.

    Background It has been suggested that GastroPanel might be a useful tool for the diagnosis of chronic atrophic gastritis (CAG) measuring four biomarkers in blood: basal gastrin-17 (G17), pepsinogen I and II (PGI and PGII), and Helicobacter pylori antibodies. Aim To determine the accuracy of GastroPanel for the diagnosis of CAG. Methods This was a prospective, blinded, multicenter study that included dyspeptic patients. G17, PGI, and PGII were determined by enzyme immunoassays. Three antrum and two corpus biopsies were obtained for standard histological analysis and rapid urease test. Biopsies were analyzed by a single blinded expert pathologist. Results Ninety-one patients were included (77% women, mean age 44 years, 51% H. pylori positive, 17% with CAG). G17 was reduced in patients with antrum CAG (5.4 vs. 13.4 pmol/l; P<0.01) and increased in patients with corpus CAG (11 vs. 24 pmol/l; P<0.05), but its accuracy was only acceptable in the case of corpus localization [area under the receiver operating characteristic curve (AUC), 74%]; PGII difference was almost statistically significant only when testing for corpus atrophy (33 vs. 21 μg/l; P=0.05; AUC=72%). The PGI and PGI/PGII ratio showed no significant differences (AUCs were all unacceptably low). Helicobacter pylori antibody levels were higher in H. pylori-infected patients (251 vs. 109 EIU, P=0.01; AUC=70). The accuracy of GastroPanel for the diagnosis of CAG was as follows: sensitivity 50%; specificity 80%; positive 25% and negative 92% predictive values; and positive 2.4 and negative 0.6 likelihood ratios. Conclusion GastroPanel is not accurate enough for the diagnosis of CAG; thus, its systematic use in clinical practice cannot be recommended. PMID:25014624

    AIM: To determine the association between H pylori infection and serum ghrelin levels in patients without atrophic gastritis.METHODS: Fifty consecutive patients (24 males and 26 females) with either H pylori-positive gastritis (n = 34) or H pylori-negative gastritis (n = 16) with normal gastric acid secretion determined by 24-h pHmetry and without atrophic gastritis in histopathology were enrolled in this study. Thirty-four H pylori-infected patients were treated with triple therapy consisting of a daily regimen of 30 mg lansoprazole bid, 1 g amoxicillin bid and 500 mg clarithromycin bid for 14 d, followed by an additional 4 wk of 30 mg lansoprazol treatment. H pylori infection was eradicated in 23 of 34 (67.6%) patients. H pylori-positive patients were given eradication therapy. Gastric acidity was determined via intragastric pH catethers. Serum ghrelin was measured by radioimmunoassay (RIA).RESULTS: There was no significant difference in plasma ghrelin levels between H pylori -positive and H pylori-negative groups (81.10 ± 162.66 ng/L vs 76.51 ± 122.94 ng/L). In addition, there was no significant difference in plasma ghrelin levels and gastric acidity levels measured before and 3 mo after the eradication therapy.CONCLUSION: H pylori infection does not influence ghrelin secretion in patients with chronic gastritis without atrophic gastritis.

    Objective: To observe the clinical therapeutic effects of acupuncture and moxibustion in treating chronic atrophic gastritis. Methods: Patients who met the criteria were randomly divided into the treatment groups consisting of the acupuncture group (30 cases) and the acupuncture-moxibustion group (30 cases), and the control group (28 cases). After two months of treatment, observed were safety and the curative effects,through general physical check ups, routine examinations of blood, urine and feces, and symptoms,pathology and gastrin before, during and after the treatment. Results: 1) The treatment groups showed significant superiorities in the improvement of symptoms, with the acupuncture-moxibustion group showing the best therapeutic effects. 2) The acupuncture-moxibustion group showed marked differences before and after the treatment in the improvement of glandular atrophy and intestinal metaplasia, with a total effective rate of 66.67%. 3) After the treatment, the three groups all showed marked improvement in the level of serum gastrin, with the acupuncture-moxibustion group showing the best effects. Conclusion: Acupuncture and moxibustion have definite therapeutic effects for chronic atrophic gastritis, especially in improving the symptoms. Acupuncture or acupuncture combined with moxibustion can provide possibilities in reversing the pathologic changes of glandular atrophy and intestinal metaplasia for patients with chronic atrophic gastritis. Acupuncture-moxibustion is really an effective and safe therapy for chronic atrophic gastritis.

    Aim: To investigate the effect of geranylgeranylacetone (GGA) on the progres-sion of atrophic gastritis in rats and its potential mechanism. Methods: Atrophic gastritis was induced in Sprague-Dawley rats with 0.1% ammonia solution, 60% ethanol, and 20 mmol/L deoxycholic acid for 24 weeks. Accompanied by the induction of atrophic gastritis, 200 mg/kg GGA was administered by oral gavage for 8 weeks (weeks 17-24). The histological changes in gastric mucosa were quantitated by the index of inflammation, the gastric mucosal thickness, and the amount of glands of 1 mm horizontal length in antrum. Endogenous heat shock protein (HSP)70 levels and distribution were determined by immunoblotting and immunohistochemistry in gastric mucosa. Results: GGA alleviated the pathologi-cal progression of atrophic gastritis with inflammation relief (inflammation index: 1.40 in the GGA group and 1.65 in the atrophic gastritis group) and glandular restoration (rnucosal thickness and quantity of glands: 194.3 μm and 38.7 mm in the GGA group; 123.3 μm and 32.7 mm in the atrophic gastritis group; P<0.05). GGA significantly induced HSP70 synthesis (P<0.05). Moreover, quercetin, an inhibitor of HSP70 expression, aggravated the infiltration of inflammatory cells and glandular loss in the antrum. Conclusion: GGA prevented the progression of atrophic gastritis in rats via the induction of HSP70 expression.

    The relationship between serum PG I, PG II levels and extent of atrophic gastritis was examined. The subjects were 64 patients (male: 32, female: 32, 51.9 years old on average) with established diagnosis of either atrophic gastritis or normal. In the X-ray gastric examination, Fuji Computed Radiography (FCR) was used to obtain clear-cut images of the gastric area. Concerning the serum PG I level, patients in the group with atrophic gastritis showed lower levels than those of the people in the group with no atrophic change, but the variation was wide, and no definite tendency was seen in the relationship between the atrophic change and the serum PG I levels. Concerning the serum PG II level, as the atrophic change progresses, the serum PG II level tended to increase gradually. A significant reduction in the PG I/II ratio was seen in the group with atrophic changes (p<0.01) in comparison with the group with no atrophic changes, and the PG I/II value tended to decrease. In conclusion, as a relationship between the atrophic change and the serum PG levels had a wide variation, we considered it to be difficult to understand the presence and extent of the atrophic gastritis by measuring serum PG levels.

    AIM: To investigate the possible relationships between gastric autoimmune phenomena and clinical presentations of this disorder, in consecutive atrophic body gastritis patients.METHODS: A total of 140 atrophic body gastritis patients,diagnosed as consecutive outpatients presenting with macrocytic or iron deficiency anemia, or longstanding dyspepsia underwent gastroscopy with antral and body biopsies, assay of intrinsic factor, parietal cells and Helicobacter pylori(H pylori) antibodies. Gastritis was assessed according to Sydney System.RESULTS: Parietal cell antibodies were equally distributed in all clinical presentations, whereas the positivity of intrinsic factor antibodies (49/140, 35%) was significantly higher in pernicious anemia patients (49.2%) than in iron deficiency (21.1%) and dyspeptic patients (27.8%). No specific pattern of autoantibodies was related to the clinical presentations of atrophic body gastritis. A positive correlation was obtained between the body atrophy score and the intrinsic factor antibody levels (r = 0.2216,P = 0.0085). Associated autoimmune diseases were present in 25/140 (17.9%) patients, but the prevalence of autoimmune diseases was comparable, irrespective of the clinical presentations.CONCLUSION: The so-called hallmarks of gastric autoimmunity, particularly in intrinsic factor antibody cannot be usefully employed in defining an autoimmune pattern in the clinical presentations of ABG.

    AIM: To investigate a pathophysiological role of cathepsin W (CatW), a putative thiol-dependent cysteine protease,which is specifically expressed in cytotoxic lymphocytes,in different types of chronic inflammation of the gastric mucosa.METHODS: Gastric and duodenal biopsies of patients with Helicobacter pylori ( H pylori)-associated active gastritis ( Hp,n = 19), chemically induced reactive gastritis (CG, n = 17),autoimmune atrophic gastritis (AIG, n = 20), lymphocytic corpus gastritis (LG, n = 29), celiac disease (CD, n = 10),and corresponding controls (n = 24) were analyzed by immunohistochemistry for the expression of CatW and CD45. Furthermore, immunohistochemical double staining with anti-CD3 and anti-cathepsin was performed for the samples of AIG.RESULTS: Median values of CatW-expressing cells among CD45-positive immune cells were between 2% and 6% for normal gastric mucosa, CG, and LG, whereas the corresponding value was significantly increased for AIG (24.7%, P<0.001) and significantly decreased for HP (0.7%, P<0.05). Double staining with anti-CD3 and antiCatW antibodies revealed that >90% of CatW-expressing cells in gastric mucosa of AIG were T cells. Duodenal mucosa had significantly more CatW/CD45-positive cells than normal gastric mucosa (median: 17.8% vs 2%, P<0.01).The corresponding proportion of CatW/CD45-positive cells was decreased in CD compared to duodenal mucosa (median: 2.1% vs 17.8%, P<0.05).CONCLUSION: The opposite findings regarding the presence of CatW-positive cells in AIG (increase) and CD (decrease) reflects the different cellular composition of immune cells involved in the pathogenesis of these diseases.

    In a 37-year-old woman with chronic watery diarrhea of three years duration, the diagnostic of collagenous colitis was established by optical and ultrastructural examination of rectal and colonic biopsies. No other cause of diarrhea could be found. Moreover, this patient had also selective IgA deficiency, Grave's disease and chronic atrophic gastritis of auto-immune type. Sequential treatments with loperamide, cholestyramine and antibiotics did not modified diarrhea which improved with salazosulfapyridine and betamethasone enemas. These observations suggest that collagenous colitis might be a part of the spectrum of enteropathies associated with immunoglobulin deficiencies. PMID:3840757

    AIM: To study the effects of He-Ne laser irradiation on experimental chronic atrophic gastritis (CAG) in rats.METHODS: Sixty-three male adult Wistar rats were randomly divided into five groups including normal control group, model control group and three different dosages He-Ne laser groups. The chronic atrophic gastritis (CAG)model in rats was made by pouring medicine which was a kind of mixed liquor including 2% sodium salicylate and 30% alcohol down the throat for 8 wk to stimulate rat gastric mucosa, combining with irregular fasting and compulsive sporting as pathogenic factors; 3.36, 4.80, and 6.24J/cm2doses of He-Ne laser were used, respectively for three different treatment groups, once a day for 20 d. The pH value of diluted gastric acid was determined by acidimeter,the histopathological changes such as the inflammatory degrees in gastric mucosa, the morphology and structure of parietal cells were observed, and the thickness of mucosa was measured by micrometer under optical microscope.RESULTS: In model control group, the secretion of gastric acid was little, pathologic morphological changes in gastric mucosa such as thinner mucous, atrophic glands, notable inflammatory infiltration were found. After 3.36 J/cm2 dose of He-Ne laser treatment for 20 d, the secretion of gastric acid was increased (P<0.05), the thickness of gastric mucosa was significantly thicker than that in model control group (P<0.01), the gastric mucosal inflammation cells were decreased (P<0.05). Morphology, structure and volume of the parietal cells all recuperated or were closed to normal.CONCLUSION: 3.36J/cm2 dose of He-Ne laser has a significant effect on CAG in rats.

    AIM: To investigate the association of TNF polymorphisms with chronic atrophic gastritis (CAG) and gastric adenocarcinoma in Chinese Han patients.METHODS: The TNFa-e 5 microsatellites and 3 RFLP sites were typed using PCR technique, followed by high-voltage denaturing PAGE with silver staining and restriction enzyme digestion respectively in specimens from 53 patients with CAG and 56 patients with gastric adenocarcinoma and 164 healthy controls. The PCR products were cloned and sequenced.RESULTS: The frequency of TNF-β Ncol*1/2 genotype was higher in patients with chronic atrophic gastritis than in healthy controls, but no significant difference was observed (60.38% vs 46.34%, P=0.076). The frequency of TNa10 allele was significantly higher in patients with chronic atrophic gastritis than in healthy controls (19.81% vs 11.89%,P=0.04). However, it did not relate to age, gender, atrophic degree or intestinal metaplasia in patients with chronic atrophic gastritis. The frequency of TNF-β Ncol*1/2 and d2/d6 genotypes were significantly higher in patients with gastric adenocarcinoma than in healthy individuals(P>0.05).However, TNF-β Ncol*1/2 and d2/d6 genotypes did not relate to age, gender, grade of differentiation and clinicopathologic stage in patients with gastric adenocarcinoma. The frequency of TNFa6b5c1 haplotype homozygote was significantly lower in patients with gastric adenocarcinoma than in healthy controls (1.79% vs15.85%, P=0.006).CONCLUSION: TNFa10 allele may be a risk factor for chronic atrophic gastritis. TNF-β Ncol*1/2 and d2/d6 genotypes are associated with the susceptibility to gastric adenocarcinoma,whereas TNFa6b5c1 haplotype homozygote may contribute to the resistance against gastric adenocarcinoma.

    AIM: To determine the association of Helicobacter pylori (H pylon) CagA+ infection and pro-inflammatory poly-morphisms of the genes interleukin (IL)-IRN and IL-1B with the risk of gastric atrophy and peptic ulcers in a dyspeptic population in Costa Rica, a country with high incidence and mortality of gastric cancer. METHODS: Seven biopsy specimens, a fasting blood sample and a questionnaire concerning nutritional and sociodemographic factors were obtained from 501 con-secutive patients who had undergone endoscopy for dyspeptic symptoms. A histopathological diagnosis was made. Pepsinogen concentrations were analyzed by enzyme linked immunosorbent assay (ELISA). Infection with H pylori CagA* was determined by serology and polymerase chain reaction (PCR). IL-1B and IL-1RN polymorphisms genotyping was performed by PCR-restriction fragment length polymorphism (PCR-RFLP) and PCR respectively. RESULTS: In this dyspeptic population, 86% wereHpy/ori positive and of these, 67.8% were positive forCagA. Atrophic antral gastritis (AAG) was associatedwith CagA+ status [odd ratio (OR) = 4.1; P < 0.000]and fruit consumption (OR = 0.3; P < 0.00). Atrophicbody gastritis (ABG) was associated with pepsinogenPGI/PGII < 3.4 (OR = 4.9; P < 0.04) and alcoholconsumption (OR = 7.3; P < 0.02). Duodenal ulcerwas associated with CagA+ (OR = 2.9; P < 0.04) andsmoking (OR = 2.4; P < 0.04). PGI < 60 μg/L as wellas PGI/PGII < 3.4 were associated with CagA+. CONCLUSION: In a dyspeptic population in Costa Rica,H pylori CagA+ is not associated with ABG, but it is arisk factor for AAG. The pro-inflammatory cytokine poly-morphisms IL-1B + 3945 and IL-1RN are not associatedwith the atrophic lesions of this dyspeptic population.

    Chronic atrophic gastritis (CAG) is an inflammatory condition characterized by the loss of gastric glandular structures which are replaced by connective tissue (non-metaplastic atrophy) or by glandular structures inappropriate for location (metaplastic atrophy).Epidemiological data suggest that CAG is associated with two different types of tumors:Intestinal-type gastric cancer (GC) and type Ⅰ gastric carcinoid (T I GC).The pathophysiological mechanisms which lead to the development of these gastric tumors are different.It is accepted that a multistep process initiating from Helicobacterpylori-related chronic inflammation of the gastric mucosa progresses to CAG,intestinal metaplasia,dysplasia and,finally,leads to the development of GC.The T I GC is a gastrin-dependent tumor and the chronic elevation of gastrin,which is associated with CAG,stimulates the growth of enterochromaffin-like cells with their hyperplasia leading to the development of T I GC.Thus,several events occur in the gastric mucosa before the development of intestinal-type GC and/or T I GC and these take several years.Knowledge of CAG incidence from superficial gastritis,its prevalence in different clinical settings and possible risk factors associated with the progression of this condition to gastric neoplasias are important issues.This editorial intends to provide a brief review of the main studies regarding incidence and prevalence or CAG and risk factors for the development of gastric neoplasias.

    Full Text Available Background/Aim. Autoimmune atrophic fundic gastritis induces the pernicious anemia (PA, as well as the changes in both epithelium and endocrine cells of gastric mucosa. The most important complications are: achlorhydria, hypergastrinemia, gastric cancer and enterochromaffin-like ( ECL carcinoid. The aim of this study was to examine ECL carcinoid histogenesis in A-gastritis associated with PA. Methods. During the period from 2000−2006, 65 patients with PA and 30 patients of the control group were examined. Histopathological examination was done in endoscopical biopsies of gastric mucosa fixed in 10% formaldehyde. Paraffin sections were stained with classic hematoxylin-eosin (HE; histochemical AB-PAS (pH 2.5, cytochemical argyrophilic Servier-Munger′s and immunocytochemical PAP methods for G cell identification and chromogranin A antibodies - specific marker for neuroendocrine ECL cells. Both G and ECL cells were counted per 20 fields, of surface 0.0245312 mm2 by a field. Basal gastrin serum levels were also examined by using radioimmunoassay (RIA method. The obtained results were statisticaly calculated by using Student΄s t test. Results. Marked antral G cell hyperplasia associated with corporal ECL hyperplasia was found. ECL cell hyperplasia was of simplex, linear, adenomatoid type to the pattern of intramucous ECL cell carcinoid. An average number of G cells was statistically significant in the patients with PA as compared to the control group (p < 0.05 as well as an average number of ECL cells. Conclusion. We concluded that antral G cell hyperplasia accompanied by gastrinemia induces ECL hyperplasia and ECL corporal carcinoid in A-gastritis and that their histogenesis develops trough simple, linear and adenomatoide hyperplasia. .

    AIM: To investigate the role of artificial neural networks in predicting the presence of thyroid disease in atrophic body gastritis patients.METHODS: A dataset of 29 input variables of 253 atrophic body gastritis patients was applied to artificial neural networks (ANNs) using a data optimisation procedure (standard ANNs, T&T-IS protocol, TWIST protocol). The target variable was the presence of thyroid disease.RESULTS: Standard ANNs obtained a mean accuracy of 64.4% with a sensitivity of 69% and a specificity of 59.8% in recognizing atrophic body gastritis patients with thyroid disease. The optimization procedures (T&T-IS and TWIST protocol) improved the performance of the recognition task yielding a mean accuracy, sensitivity and specificity of 74.7% and 75.8%, 78.8% and 81.8%, and 70.5% and 69.9%, respectively. The increase of sensitivity of the TWIST protocol was statistically significant compared to T&T-IS.CONCLUSION: This study suggests that artificial neural networks may be taken into consideration as a potential clinical decision-support tool for identifying ABG patients at risk for harbouring an unknown thyroid disease and thus requiring diagnostic work-up of their thyroid status.

    Full Text Available Previous in vitro and animal experiments have shown that sulforaphane, which is abundant in broccoli, inhibits Helicobacter pylori (H. pylori infection and blocks gastric tumor formation. This suggests that broccoli consumption prevents chronic atrophic gastritis (CAG introduced by H. pylori infection and, therefore, gastric cancer. For an epidemiological investigation of the relationship between the broccoli consumption and CAG, a cross-sectional study of 438 male employees, aged 39 to 60 years, of a Japanese steel company was conducted. CAG was serologically determined with serum cut-off values set at pepsinogen I < or = 70 ng/ml and a ratio of serum pepsinogen I/pepsinogen II < or = 3.0. Broccoli consumption (weekly frequency and diet were monitored by using a 31-item food frequency questionnaire. The prevalence of CAG among men who ate broccoli once or more weekly was twice as high as that among men who consumed a negligible amount (P < 0.05. Multiple logistic regression analysis indicated that broccoli consumption once or more weekly significantly increased the risk for CAG (odds ratio, 3.06; 95% confidence interval, 1.12-8.38; P < 0.05, after controlling for age, education, cigarette smoking, and alcohol consumption. The present study failed to show an expected association between frequent broccoli consumption and a low prevalence of CAG.

    AIM: To demonstrate the effect of Hewei-Decoction(Decoction for regulating the stomach) on chronic atrophic gastritis (CAG) and eradication of Helicobacter pylori.METHODS: Ninety patients with CAG entering the investigation were divided into six differentiation syndromes, based on their major symptoms and signs.Hewei-Decoction was taken by all the patients orally for 4or 8 wk. The efficacy was assessed by both the composite accumulation of reduced scores of major symptoms and the eradication of H pylori.χ2 test was used to compare the efficacy between Hpylori-positive and negative cases,and to disclose the relationship between efficacy and eradication of H pylori.REStULTS: In patients with six different syndrome types,the efficacy of Hewei-Decoction was 91.67% (11/12),92.86% (13/14), 97.22% (35/36), 87.50% (14/16),75.00% (6/8), 75.00% (3/4) respectively. The rate of highly efficacious was 58.33% (7/12), 50.00% (7/14),77.78% (28/36), 62.50% (10/16), 12.50% (1/8) and25.00% (1/4), respectively. The total efficacy was 91.11%(82/90), and the rate of highly efficacious was 60.00%(54/90). The eradication rate of H pyloriwas 67.86%(38/56). The therapeutic effect of Hewei-Decoction was better in H pylori positive cases than that in Hpylori-negative cases with the total effect of 96.43% vs82.35% (P<0.05).In 56 H pylori positive cases, the therapeutic effect was better in H pylori eradicated cases than that in H pyloriexistent cases with the total effect of 97.37% vs 72.22%(P<0.01).CONCLUSION: Hewei-Decoction is effective in most cases of all the syndrome types. The results indicate that eradication of H pylori is one of the important mechanisms for alleviation of symptoms and signs. Also, the decoction is efficacious in H pylori-negative cases.

    Objective: To study the pathologic change and molecular regulation in cell proliferation and apoptosis of gastric mucosa in rats with chronic atrophic gastritis (CAG), and evaluate the possible mechanisms. Methods: Rats were administered with 60% alcohol or 2% salicylate sodium, 20 mmol/L deoxycholate sodium and 0.1% ammonia water to establish chronic atrophic gastritis (CAG) models. The gastric specimens were prepared for microscopic view with hematoxylin and eosin (H-E)and alcian blue (A-B) stain. The number of infiltrated inflammatory cells, the thickness of the mucosa gland layer (μm) and the number of gastric glands were calculated. The damage of barrier in mucosa with erosion or ulceration, and the thickness of mucin were examined by scanned electron microscope (SEM). The levels of PGE2, EGF (epiderminal growth factor) and gastrin in the serum were measured with radioimmunoassay or ELISA method. The immunohistochemistry method was used to observe the number of G cells, the expression of protein of EGFR (EGF receptor), C-erbB-2, p53, p16 and bcl-2 in gastric tissue. Results:Under SEM observation, the gastric mucosa was diffused erosion or ulceration and the thickness of mucin was decreased. Compared with normal rats, the grade of inflammatory cell infiltration in CAG rats was elevated, whereas the thickness and number of gastric gland were significantly lower (P<0.05). Compared with normal level of (0.61+0.28) μg/L, EGF in CAG (2.2±0.83) μg/L was significantly higher (P<0.05). The levels of PGE2 and gastrin in serum were significantly lower in CAG rats than that in normal rats (P<0.05). Immunohistochemistry detection showed that the number of G cell in antrum was lower in CAG group (P<0.05). Immuno-stain showed EGFR protein expression in the basal and bilateral membrane, and the cytoplasma in atrophic gastric gland, while negative expression was observed in normal gastric epithelial cells. Positive staining of p53 and p16 protein was localized in

    To summarize Professor LIU Feng-bin's clinical experience and theoretical thoughts on chronic atrophic gastritis (CAG), the study group designed a retrospective study on his case series and expert interview. First of all, the data of CAG patients treated in the First Affiliated Hospital of Guangzhou University of Chinese Medicine between 2009 and 2013, e. g. herbs, diseases, syndrome type, prescription amount and number of herbs, was collected and processed. The statistical description and binary logistic regression were used to determined the syndrome type, initial basic remedy and modification. During the statistics, a complete and sub-group analysis was performed simultaneously. After the expert interview, the syndrome type and medication were finalized. As a result, a total of 228 CAG patients aged at (50.30 ± 10.18) were collected, including 151 males (66.23%). Of them, the TCM diagnosis and syndrome type were extracted from the information of 157 patients, including 115 cases with gastric stuffiness, 23 cases with gastric pain, 19 missing cases, 2 cases with spleen-stomach weakness syndrome, 57 cases with spleen deficiency and dampness-heat syndrome, 18 cases with spleen-stomach disharmony syndrome, 23 cases with syndrome of liver depression syndrome, 21 cases with liver qi invading stomach syndrome and 26 qi and yin deficiency syndrome, respectively. All of the 228 patients used totally 104 herbs, while the subgroups with 157 patients used 94 herbs. The most frequently used 15 herbs used in each groups were analyzed to determine the initial basic remedy and modification. Subsequently, based on the information of the sub-groups with 157 patients, with the syndrome type as the dependent variable, the logistic regression analysis was made on the most frequently used 32 herbs, in order to determined the modification in herbs for different syndrome types. After experts reviewed and modified, they believed the main causes of CAG were dietary irregularities

    AIM: To investigate whether ANNs and LDA could recognize patients with ABG in a database, containing only clinical and biochemical variables, of a pool of patients with and without ABG, by selecting the most predictive variables and by reducing input data to the minimum.METHODS: Data was collected from 350 consecutive outpatients (263 with ABG, 87 with non-atrophic gastritis and/or celiac disease [controls]). Structured questionnaires with 22 items (anagraphic, anamnestic, clinical, and biochemical data) were filled out for each patient. All patients underwent gastroscopy with biopsies. ANNs and LDA were applied to recognize patients with ABG.Experiment 1: random selection on 37 variables, experiment 2: optimization process on 30 variables, experiment 3:input data reduction on 8 variables, experiment 4: use of only clinical input data on 5 variables, and experiment 5:use of only serological variables.RESULTS: In experiment 1, overall accuracies of ANNs and LDA were 96.6% and 94.6%, respectively, for predicting patients with ABG. In experiment 2, ANNs and LDA reached an overall accuracy of 98.8% and 96.8%,respectively. In experiment 3, overall accuracy of ANNs was 98.4%. In experiment 4, overall accuracies of ANNs and LDA were, respectively, 91.3% and 88.6%. In experiment 5, overall accuracies of ANNs and LDA were,respectively, 97.7% and 94.5%.CONCLUSION: This preliminary study suggests that advanced statistical methods, not only ANNs, but also LDA,may contribute to better address bioptic sampling during gastroscopy in a subset of patients in whom ABG may be suspected on the basis of aspecific gastrointestinal symptoms or non-digestive disorders.

    Full Text Available BACKGROUND: The aim of this study was to investigate the interaction effects of pri-let-7a-1 rs10739971 with pepsinogen C (PGC and excision repair cross complementing group 6 (ERCC6 gene polymorphisms and its association with the risks of gastric cancer and atrophic gastritis. We hoped to identify miRNA polymorphism or a combination of several polymorphisms that could serve as biomarkers for predicting the risk of gastric cancer and its precancerous diseases. METHODS: Sequenom MassARRAY platform method was used to detect polymorphisms of pri-let-7a-1 rs10739971 G → A, PGC rs4711690 C → G, PGC rs6458238 G → A, PGC rs9471643 G → C, and ERCC6 rs1917799 in 471 gastric cancer patients, 645 atrophic gastritis patients and 717 controls. RESULTS: An interaction effect of pri-let-7a-1 rs10739971 polymorphism with ERCC6 rs1917799 polymorphism was observed for the risk of gastric cancer (P interaction = 0.026; and interaction effects of pri-let-7a-1 rs10739971 polymorphism with PGC rs6458238 polymorphism (P interaction = 0.012 and PGC rs9471643 polymorphism (P interaction = 0.039 were observed for the risk of atrophic gastritis. CONCLUSION: The combination of pri-let-7a-1 rs10739971 polymorphism and ERCC6 and PGC polymorphisms could provide a greater prediction potential than a single polymorphism on its own. Large-scale studies and molecular mechanism research are needed to confirm our findings.

    The polymorphisms in trefoil factor (TFF) gene family that protect gastrointestinal epithelium might influence individual vulnerability to gastric cancer (GC) and atrophic gastritis. We used the Sequenom MassARRAY platform to identify the genotypes of TFF2 rs3814896 and TFF3 rs9981660 polymorphisms in 478 GC patients, 652 atrophic gastritis patients, and 724 controls. For the TFF2 rs3814896 polymorphism, in the subgroup aged ≤ 50 years, we found that AG+GG genotypes were associated with a 0.746-fold decreased risk of atrophic gastritis [p=0.023, 95% confidence interval (CI)=0.580-0.960], a 0.626-fold decreased risk of GC (p=0.005, 95% CI=0.451-0.868), and a 0.663-fold decreased risk of diffuse-type GC (p=0.034, 95% CI=0.452-0.970) compared with the common AA genotype. For the TFF3 rs9981660 polymorphism, in the male subgroup, individuals with variant AG+AA genotype were associated with a 0.761-fold decreased risk of diffuse-type GC compared with the common GG genotype (p=0.043, 95% CI=0.584-0.992). Additionally, we found that in subjects aged ≤ 50 years compared with common AA genotype, TFF2 rs3814896 AG+GG genotypes were associated with increased TFF2 mRNA levels in the total gastric cancer specimens and in the diffuse-type gastric cancer specimens; and in males aged ≤ 50 years compared with common GG genotype, TFF3 rs9981660 AA+AG genotypes were associated with TFF3 mRNA levels in diffuse-type gastric cancer tissues and their corresponding non-cancerous tissues. To our knowledge, this is the first report of an association between the TFF2 rs3814896 AG+GG genotypes and decreased risks of GC, diffuse-type GC, and atrophic gastritis in younger people aged ≤ 50 years, and an association between TFF3 rs9981660 AG+AA genotype and decreased risk of diffuse-type GC in men. Moreover, we found that TFF2 rs3814896 AG+GG genotypes in people aged ≤ 50 years and TFF3 rs9981660 AG+AA genotypes in younger males with diffuse-type GC were associated with higher levels of

    H. pylori (Hp) -induced atrophic gastritis is a well-known risk factor for the development of gastric cancer. Whether Hp eradication can prevent or retard the progress of atrophy and metaplasia has been the topic of numerous studies but the subject remains controversial. Recently, the increased expression of ornithine decarboxylase (ODC), gastrin and cyclooxygenase (COX)-2 has been shown to be increased in premalignant lesions in gastric mucosa and to play an essential role in the malignant transformation. The aim of the study is to assess the effect of eradication therapy on atrophic gastritis and analyze the gene expression for ODC, COX-2 and gastrin in gastric mucosa after succesful eradication in patients with atrophic gastritis. Twenty patients with chronic atrophic gastritis including both corpus and antrum of the stomach were included in this study. Four antral mucosal biopsy specimens were obtained from antrum and four from corpus. The histopathologic evaluation of gastritis was based on Sydney classification of gastritis. All patients were Hp positive based on the [13C] urea breath test (UBT) and the presence of anti-Hp IgG and anti-CagA-antibodies detected by ELISA. The patients were then eradicated with triple therapy consiting of omeprazol (2 x 20 mg), amoxycillin (2 x 1 g) and clarithromycin (2 x 500 mg) for seven days and vitamin C 1 g/day for three months. In gastric mucosal samples obtained from the antrum and corpus before and after eradication, the mRNA expression for ODC, COX-2, and gastrin was assessed by reverse-transcription polymerase chain reaction (RT-PCR). In all patients the gastric secretory analysis was performed by measuring gastric acid output and serum gastrin levels. After triple therapy the successful eradication assessed by UBT was observed in 95% of patients. In 45% of patients the infection with CagA-positive Hp strain was observed. Three months after eradication a significant reduction in the gastric activity (neutrophilic

    Full Text Available INTRODUCTION: Autoimmune chronic atrophic gastritis (CAG causes hypochlorhydria and hypergastrinaemia, which can lead to enterochromaffin-like (ECL cell hyperplasia and gastric neuroendocrine tumours (type 1 gastric NETs. Most behave indolently, but some larger tumours metastasise. Antrectomy, which removes the source of the hypergastrinaemia, usually causes tumour regression. Non-clinical and healthy-subject studies have shown that netazepide (YF476 is a potent, highly selective and orally-active gastrin/CCK-2 receptor antagonist. Also, it is effective in animal models of ECL-cell tumours induced by hypergastrinaemia. AIM: To assess the effect of netazepide on tumour biomarkers, number and size in patients with type I gastric NETs. METHODS: We studied 8 patients with multiple tumours and raised circulating gastrin and chromogranin A (CgA concentrations in an open trial of oral netazepide for 12 weeks, with follow-up 12 weeks later. At 0, 6, 12 and 24 weeks, we carried out gastroscopy, counted and measured tumours, and took biopsies to assess abundances of several ECL-cell constituents. At 0, 3, 6, 9, 12 and 24 weeks, we measured circulating gastrin and CgA and assessed safety and tolerability. RESULTS: Netazepide was safe and well tolerated. Abundances of CgA (p<0.05, histidine decarboxylase (p<0.05 and matrix metalloproteinase-7(p<0.10 were reduced at 6 and 12 weeks, but were raised again at follow-up. Likewise, plasma CgA was reduced at 3 weeks (p<0.01, remained so until 12 weeks, but was raised again at follow-up. Tumours were fewer and the size of the largest one was smaller (p<0.05 at 12 weeks, and remained so at follow-up. Serum gastrin was unaffected. CONCLUSION: The reduction in abundances, plasma CgA, and tumour number and size by netazepide show that type 1 NETs are gastrin-dependent tumours. Failure of netazepide to increase serum gastrin further is consistent with achlorhydria. Netazepide is a potential new treatment for type 1 NETs

    Introduction: Chronic gastritis is inflammation of the gastric mucosa. It can be non-atrophic and atrophic. Atrophy isdefined as the loss of appropriate glands. It is frequently located in antral mucosa as consequence of Helicobacter pylori infectionand it is associated with intestinal gastric cancer. Goal: Describe histopathological and demographic characteristics of atrophicgastritis. Matherial and methods: We assessed the pathological reports of 100 patients with atrophic gastritis whose characteristicswere evaluated by using a semiquantitative scale of Sidney system of classification of gastritis. To assess the significance betweenthe incidence of various parametres we used ;~2 test. Results: We found that the difference in frequency of atrophic gastritis betweenmen and women was not statistically significant. The difference in distribution is statistically significant in favor of the antrum.Among patients who have atrophy with Helicobacterpylori infection and intestinal metaplasia and those who do not have metaplasia,it was found that the difference is highly statistically significant. Conclusion: The most frequent localisation of atrophic gastritis isantral mucosa. There is no difference between men and women in frequency of atrophic gastritis, while the aging is related with moreoften occurrence of atrophic gastritis.

    In the present paper, we report a case of rare collagenous gastritis. The patient was a 25-year-old man who had experienced nausea, abdominal distention and epigastralgia since 2005. Esophagogastroduodenoscopy (EGD) carried out at initial examination by the patient's local doctor revealed an extensively discolored depression from the upper gastric body to the lower gastric body, mainly including the greater curvature, accompanied by residual mucosa with multiple islands and nodularity with a cobblestone appearance. Initial biopsies sampled from the nodules and accompanying atrophic mucosa were diagnosed as chronic gastritis. In August, 2011, the patient was referred to Tohoku University Hospital for observation and treatment. EGD at our hospital showed the same findings as those by the patient's local doctor. Pathological findings included a membranous collagen band in the superficial layer area of the gastric mucosa, which led to a diagnosis of collagenous gastritis. Collagenous gastritis is an extremely rare disease, but it is important to recognize its characteristic endoscopic findings to make a diagnosis. PMID:23363075

    Objective To observe the ultrastructural changes of gastric mucosa of rats with atrophic gastritis caused by hot water and investigate the pathogenesis of atrophic gastritis and the relationship between chronic atrophic gastritis (CAG) and hot diet. Methods The rat atrophic gastritis model was induced by gavage with hot water(55℃, 150g/mL, 2.5mL/d x 32 weeks). Histopathological methods were used to examine the selected gastric glands and antrum of rat. The ultrastructure of gastric mucosa were observed under scanning electromicroscope. Results (1) The optical microscope observation showed that the surface of the gastric mucosa was smooth and no erosion could be observed there in control group. There was no inflammatory infiltration in lamina propria. Nor was there edema in submucous layer or inflammatory infiltration in muscular layer. In hot water group, when hot water was given 24 weeks, the body of gastric gland of rat's gastric mucosa shrank obviously. The smooth muscle in muscular layer of mucosa had hyperplasia and got into the lamina propria of mucosa. The glandular epithelium in the up 1/3~2/3 part of the gland was atrophic. The lumen of the glards became broadened and the width of mucosa in the neck of gastric pit became narrowed. (2) The scanning electromicroscope observation showed that, in control group, the gastric mucosa was compartmentalized by crisscross grooves into many micro gastric areas, in the shape of reticulation. The epithelium was lined regularly and covered with laminar mucus. In hot water group, when hot water was given for 24 weeks, the gastric mucosa cells became atrophic. The lumen of gland was broadened and bleeding could be observed . When hot water was given for 32 weeks, besides the atrophic gastric mucosa and more broadened lumen of gland, much exfoliation of epithelium, the breakage of the cells and the focal erosion of mucosa were also found. (3) The transmission electromicroscope observation showed that the body of gland

    [Objective] Atrophic gastritis is a disease with intestinal metaplasia, and reveals that human immune system (cells, body fluids, partial immunity) is in a low state. "Spleen is a defense banier to pathogenic qi," "if spleen function maintains normal all the time, human body will not be ill," that reveals the immune role of the spleen. In modern medicine, spleen is regarded as immune response and immune material base, one of the barriers of the human immune system. Because proteomics is not anatomical concept of organs and tissues etc., but involves in certain aspects' alteration in biochemistry and internal relationship of disease processes. These physiological and pathological viewpoints are in coincident with TCM holism. From the angle of immunity micro-molecule proteome, atrophic gastritis spleen-qi deficiency substance will be elaborated.%萎缩性胃炎(AG)是人体整体免疫力(细胞、体液、局部免疫)低下,多种因素长期作用而表现胃局部、常伴肠化的病症.“脾为之卫”、“四季脾旺不受邪”,表现脾的免疫防卫作用,现代医学也认为脾是免疫应答和产生免疫效应物质的重要基地,人体免疫系统的屏障之一.由于蛋白质组学的研究不是从器官组织的解剖学定位出发,强调生物化学某一环节的改变和疾病过程的内在联系,与中医学整体的生理病理观有更多的切合点,本文旨在从免疫小分子蛋白质组表达规律的角度观察与AG脾气虚证的相关性.

    The mucosa of the esophagus, the stomach, the small intestine, the large intestine and rectum are unremittingly challenged by adverse micro-environmental factors, such as ingested pathogenic and non-pathogenic bacteria, and harsh secretions with digestive properties with disparate pH, as well as bacteria and secretions from upstream GI organs. Despite the apparently inauspicious mixture of secretions and bacteria, the normal GI mucosa retains a healthy state of cell renewal. To by-pass the tough microenvironment, the epithelia of the GI react by speeding-up cell exfoliation, by increasing peristalsis, eliminating bacteria through secretion of plasma cell-immunoglobulins and by increasing production of natural antibacterial enzymes (lysozyme) and host defense peptides (defensin-5). Lysozyme was recently found up-regulated in Barrett's esophagitis, in chronic gastritis, in gluten-induced atrophic duodenitis (celiac disease), in collagenous colitis, in lymphocytic colitis and in Crohn's colitis. This up-regulation is a response directed towards the special types of bacteria thriving in the microenvironment in each of the aforementioned clinical inflammatory maladies. The purpose of that up-regulation is to protect the mucosa affected by the ongoing chronic inflammation. Bacterial antibiotic resistance continues to exhaust our supply of effective antibiotics. The future challenge is how to solve the increasing menace of bacterial resistance to anti-bacterial drugs. Further research on natural anti-bacterial enzymes such as lysozyme, appears mandatory.

    A study was made on the therapeutic effects of sofalcone (SU-88), an antiulcer agent, on erosive and atrophic gastritis induced experimentally by 6-month administration of 5 mmol/l of sodium taurocholate (TCA) in rats. A standard meal including sofalcone of 0.25% and 1.0% shortened the total length of erosions, normalized the mucosal thickness, and reduced collagenous fibers in the gastric mucosa in one month. The doses administered were 116.3 mg and 486.1 mg/kg/week for one month. Sofalcone, thus, had a good therapeutic effect on experimental erosive and atrophic gastritis in rats. PMID:3675690

    Collagenous gastritis is a rare condition defined histologically by a superficial subepithelial collagen layer. This study further characterizes the morphologic spectrum of collagenous gastritis by evaluating a multi-institutional series of 40 patients (26 female and 14 male). The median age at onset was 16 years (range 3-89 years), including 24 patients (60%) under age 18. Twelve patients (30%) had associated celiac disease, collagenous sprue, or collagenous colitis. Hematoxylin and eosin slides were reviewed in biopsies from all patients and tenascin, gastrin, eotaxin, and IgG4/IgG immunohistochemical stains were applied to a subset. The distribution of subepithelial collagen favored the body/fundus in pediatric patients and the antrum in adults. There were increased surface intraepithelial lymphocytes (>25 lymphocytes/100 epithelial cells) in five patients. Three of these patients had associated celiac and/or collagenous sprue/colitis, while the remaining two had increased duodenal lymphocytosis without specific etiology. An eosinophil-rich pattern (>30 eosinophils/high power field) was seen in 21/40 (52%) patients. Seven patients' biopsies demonstrated atrophy of the gastric corpus mucosa. Tenascin immunohistochemistry highlighted the subepithelial collagen in all 21 specimens evaluated and was a more sensitive method of collagen detection in biopsies from two patients with subtle subepithelial collagen. No increased eotaxin expression was identified in 16 specimens evaluated. One of the twenty-three biopsies tested had increased IgG4-positive cells (100/high power field) with an IgG4/IgG ratio of 55%. In summary, collagenous gastritis presents three distinct histologic patterns including a lymphocytic gastritis-like pattern, an eosinophil-rich pattern, and an atrophic pattern. Eotaxin and IgG4 were not elevated enough to implicate these pathways in the pathogenesis. Tenascin immunohistochemistry can be used as a sensitive method of collagen detection. PMID

    Endoscopic visualisation of gastric atrophy is usually not feasible with conventional endoscopy. Magnifying endoscopy is helpful to analyze the subepithelial microvascular architecture as well as the mucosal surface microstructure without tissue biopsy. Using this technique we were able to describe the normal gastric microvasculature pattern and we also identified characteristic patterns in two cases of autoimmune atrophic gastritis.

    The effect of sofalcone on the glandular structure and cell proliferation in the gastric mucosa of rats with gastritis induced by the administration of sodium taurocholate (TCA) for 6 months was examined by histoquantitative analysis and [3H]thymidine autoradiography. Morphometric observation revealed that, with TCA treatment, mucosal thickness, parietal cell mass, and the ratios of the length of the glandular portion/total length of the gastric gland were decreased in both the fundic and pyloric glands. Inflammatory cell infiltration and collagenous fiber proliferation were present in the gastric mucosa following TCA and indicated the presence of atrophic gastritis. These atrophic changes and inflammatory cell infiltration were reversed by a 3 week administration of sofalcone. Cellular proliferative activity assessed by the labeling indices of the gastric mucosa increased in TCA-induced gastritis in rats. The administration of sofalcone to rats with TCA-induced gastritis significantly increased labeling indices, particularly in the pyloric glands. From these results, it appears that sofalcone stimulates the compensatory increase in proliferative activity of generative cells, which then may become available to heal the gastritis. PMID:2212544

    Collagenous gastritis, a counterpart of collagenous colitis, is a rare disorder with less than 20 cases reported in the literature. A case of collagenous gastritis in a Japanese woman in her early 20s who had been receiving treatment for atopic dermatitis and bronchial asthma is reported. The patient complained of repeated epigastric pain, and endoscopy revealed multifocal atrophic areas and scars in the gastric body. Biopsy specimens showed a thickened eosinophilic band-like structure with entrapped capillaries approximately 30-70 micro m thick beneath the surface epithelium. It was regarded as a collagen band because it was positive on Azan staining but negative on amyloid staining. This finding was accompanied by marked infiltration of mononuclear cells and eosinophils in the lamina propria; however, no evidence of lymphocytic gastritis was found. Helicobacter pylori infection was not detected and inflammatory cell infiltration was minimal in the mucosa without the collagen band. Immunohistochemical analysis revealed that the band was positive for type III and type VI collagen. The size of the collagen band did not change for 2 years. These findings suggest that subepithelial collagen deposition was due to an abnormal local immune response based on generalized allergic disorder. PMID:12608899

    Helicobacter pylori is the main aetiologic factor for chronic gastritis worldwide. The degree of inflammation and the evolution of this form of chronic gastritis can vary largely depending on bacterial virulence factors, host susceptibility factors and environmental conditions. Autoimmune gastritis is another cause of chronic inflammation in the stomach, which can occur in all age groups. This disease presents typically with vitamin B12 deficiency and pernicious anaemia. The presence of anti-parietal cell antibodies is highly specific for the diagnosis. The role of H. pylori as a trigger for autoimmune gastritis remains uncertain. Other rare conditions for chronic gastritis are chronic inflammatory conditions such as Crohn's disease or on the background of lymphocytic or collagenous gastroenteropathies. PMID:25439069

    AIM: To investigate the therapeutic effects of DA-9601 on sodium taurocholate (TCA)-induced chronic reflux gastritis in SD rats.METHODS: In this study, we have investigated the therapeutic effects of DA-9601 on chronic erosive and atrophic gastritis induced by 6 mo of TCA administration (5 mmol/L in drinking water) in SD rats. RESULTS: Four weeks of DA-9601 administration (0.065%, 0.216% in rat chow), following the withdrawal of TCA treatment, resulted in a significant decrease in total length of erosions in rats in a dose-dependent manner. Furthermore, the indicators of atrophic gastritis, such as reduced mucosal thickness and reduction in the number of parietal cells, were improved by the administration of DA-9601 in a dose-related manner. DA-9601 also attenuated inflammatory cell infiltration and the proliferation of collagenous fiber in the gastric mucosa. The improvement in the reduction of the gastric mucus was observed in the rats receiving a high dose of DA-9601 (0.216%). The therapeutic effect of DA-9601 on experimental chronic erosive gastritis was superior to that of rebamipide (1.08% in rat chow). Biochemical analyses showed increased mucosal prostaglandin E2 and reduced glutathione levels by DA-9601 treatment. CONCLUSION: We suggest that DA-9601 is apromising agent for the treatment of chronic erosive and atrophic gastritis with an etiological factor of bile reflux. Increasedmucosal prostaglandin E2 and reduced glutathione by DA-9601 treatment may be therapeutic mechanisms for chronic erosive and atrophic gastritis.

    Helicobacter pylori (H. pylori) is the etiologic agent of gastritis; it has been estimated that 50 % of the world's population could be infected by this bacteria. Gastritis may progress to chronic atrophic gastritis, a condition associated with the development of gastric cancer (GC). Several matrix metalloproteases (MMP) and tissue inhibitors of MMPs (TIMP) as well as disintegrins and metalloproteases (ADAM) have been reported as being involved in gastritis. Among other processes, these protein families participate in remodeling the extracellular matrix, cell signaling, immune response, angiogenesis, inflammation and epithelial mesenchymal transition. This systematic review analyzes the scientific evidence surrounding the relationship between members of the MMP, TIMP and ADAM families and infection by H. pylori in gastritis, considering both in vitro and in vivo studies. Given the potential clinical value of certain members of the MMP, TIMP and ADAM families as molecular markers in gastritis and the association of gastritis with GC, the need for further study is highlighted.

    A 25-year-old Japanese female was referred to our clinic for the investigation of moderate iron-deficiency anemia and epigastralgia. Endoscopic examination showed diffuse mucosal nodules in the gastric body resembling nodular gastritis, but this pattern was not observed in the antrum. Histology of the gastric biopsies taken from the gastric body showed mild atrophic mucosa with chronic active inflammation. Some of the biopsy specimens showed deposition of patchy, band-like subepithelial collagen. Four years later, the patient showed no clinical symptoms and signs. A follow-up endoscopic examination showed similar findings, which mimicked pseudopolyposis or a cobblestone-like appearance. The biopsy specimens from the depressed mucosa between the nodules revealed a thickened subepithelial collagen band with no improvement, which led to a diagnosis of collagenous gastritis. Treatment with oral administration of proton-pump inhibitors and histamine-2-receptor antagonists had proved ineffective. To make a correct diagnosis of collagenous gastritis, we should determine the characteristic endoscopic findings and take biopsies from the depressed mucosa between the nodules. PMID:26182135

    AIM: To investigate the occurrence of chromosome 3, 7,8, 9, and 17 aneuploidies, TP53 gene deletion and p53 protein expression in chronic gastritis, atrophic gastritis and gastric ulcer, and their association with H pylori infection.METHODS: Gastric biopsies from normal mucosa (NM,n = 10), chronic gastritis (CG,n =38), atrophic gastritis (CAG, n=13) and gastric ulcer (GU, n = 21) were studied using fluorescence in situ hybridization (FISH) and immunohistochemical assay. A modified Giemsa staining technique and PCR were used to detect H pylori. An association of the gastric pathologies and aneuploidies with H pylori infection was assessed.RESULTS: Aneuploidies were increasingly found from CG (21%) to CAG (31%) and to GU (62%), involving mainly monosomy and trisomy 7, trisomies 7 and 8, and trisornies 7, 8 and 17, respectively. A significant association was found between H pylori infection and aneuploidies in CAG (P= 0.0143) and GU (P= 0.0498). No TP53 deletion was found in these gastric lesions, but p53-positive immunoreactivity was detected in 45% (5/11) and 12% (2/17) of CG and GU cases, respectively. However, there was no significant association between p53 expression and H pylori infection.CONCLUSION: The occurrence of aneuploidies in benign lesions evidences chromosomal instability in early stages of gastric carcinogenesis associated with H pylori infection, which may confer proliferative advantage. The increase of p53 protein expression in CG and GU may be due to overproduction of the wild-type protein related to an inflammatory response in mucosa.

    Collagenous gastritis is a rare disease characterized by the subepithelial deposition of collagen bands thicker than 10 μm and the infiltration of inflammatory mononuclear cells in the lamina propria. Collagenous colitis and collagenous sprue have similar histological characteristics to collagenous gastritis and are thought to be part of the same disease entity. However, while collagenous colitis has become more common in the field of gastroenterology, presenting with clinical symptoms of chronic diarrhea in older patients, collagenous gastritis is rare. Since the disease was first reported in 1989, only 60 cases have been documented in the English literature. No safe and effective treatments have been identified from randomized, controlled trials. Therefore, better understanding of the disease and the reporting of more cases will help to establish diagnostic criteria and to develop therapeutic strategies. Therefore, here we review the clinical characteristics, endoscopic and histological findings, treatment, and clinical outcomes from case reports and case series published to date, and provide a summary of the latest information on the disease. This information will contribute to improved knowledge of collagenous gastritis so physicians can recognize and correctly diagnose the disease, and will help to develop a standard therapeutic strategy for future clinical trials.

    AIM: To determine the long-term prevalence of Helicobacter pylori (H pylori) gastritis in patients after partial gastric resection due to peptic ulcer, and to compare the severity of H pylori-positive gastritis in the corpus mucosa between partial gastrectomy patients and matched controls.METHODS: Endoscopic biopsies were obtained from 57 patients after partial gastric resection for histological examination using hematoxylin/eosin and Warthin-Starry staining. Gastritis was graded according to the updated Sydney system. Severity of corpus gastritis was compared between H pylori-positive partial gastrectomy patients and H pylori-positive duodenal ulcer patients matched for age and gender.RESULTS: In partial gastrectomy patients, surgery was performed 20 years (median) prior to evaluation. In 25 patients (43.8%) H pylori was detected histologically in the gastric remnant. Gastric atrophy was more common in H pylori-positive compared to H pylori-negative partial gastrectomy patients (P<0.05). The severity of corpus gastritis was significantly lower in H pylori-positive partial gastrectomy patients compared to duodenal ulcer patients (P<0.01). There were no significant differences in the activity of gastritis, atrophy and intestinal metaplasia between the two groups.CONCLUSION: The long-term prevalence of H pylorigastritis in the gastric corpus of patients who underwent partial gastric resection due to peptic ulcer disease is comparable to the general population. The expression of H pylori gastritis in the gastric remnant does not resemble the gastric cancer phenotype.

To assess the predictive value for chronic autoimmune gastritis (AIG of the combined assay of anti-parietal-cell antibodies (PCA, anti-intrinsic-factor antibodies (IFA, anti-Helicobacter pylori (Hp antibodies, and measurement of blood gastrin. Methods. We studied 181 consecutive patients with anemia, due to iron deficiency resistant to oral replacement therapy or to vitamin B12 deficiency. Results. 83 patients (45.8% tested positive for PCA and underwent gastroscopy with multiple gastric biopsies. On the basis of the histological diagnosis, PCA-positive patients were divided into 4 groups: (1 30 patients with chronic atrophic gastritis; they had high concentrations of PCA and gastrin and no detectable IFA; (2 14 subjects with metaplastic gastric atrophy; they had high PCA, IFA, and gastrin; (3 18 patients with nonspecific lymphocytic inflammation with increased PCA, normal gastrin levels, and absence of IFA; (4 21 patients with multifocal atrophic gastritis with “borderline” PCA, normal gastrin, absence of IFA and presence of anti-Hp in 100% of the cases. Conclusions. The assay of four serological markers proved particularly effective in the diagnostic classification of gastritis and highly correlated with the histological profile. As such, this laboratory diagnostic profile may be considered an authentic “serological biopsy.”

    The present study evaluated the therapeutic effects of rebamipide alone and in combination with cimetidine on experimental gastritis established by the administration of 5 mM sodium taurocholate (TCA) for 6 months in rats. Morphological and biochemical analyses were performed to determine the effects of rebamipide, administered alone or in combination with cimetidine, on chronic, atrophic and erosive gastritis. Rebamipide and cimetidine were administered to rats as a dietary admixture for 4 weeks after withdrawal of TCA. Rebamipide dose-dependently reduced the total length of the erosion, normalized the mucosal thickness and increased the number of parietal and total cells, and tended to reduce interstitial infiltration of inflammatory cells and proliferation of collagenous fibers. Moreover, histochemical and biochemical studies also showed rebamipide to be effective. Rebamipide increased the PAS-positive mucus and normalized the reduced gastric mucosal SOD activity. The therapeutic effect of rebamipide on the experimental gastritis was enhanced by the combined use of cimetidine. These results suggest that rebamipide has a therapeutic effect on chronic atrophic erosive gastritis induced by TCA, and that the mechanism of the therapeutic effect is partially due to the increase in PAS-positive mucus and gastric mucosal SOD activity. Furthermore, the enhanced effect of the combination therapy of rebamipide with cimetidine was considered to be due to the actions of both cimetidine and rebamipide. PMID:1335596

    We investigated the therapeutic effects of egualen sodium (KT1-32), a new antiulcer agent, on chronic erosive and atrophic gastritis induced by 5 months' administration of sodium taurocholate (TCA; 5 mM) in rats. The chronic gastritis was manifested by mucosal surface injuries (erosions), reduced mucosal thickness, reduction of the number of parietal cells, infiltration of inflammatory cells, and proliferation of collagenous fiber. Egualen sodium, (10-100 mg/kg, t.i.d.) administered orally to the rats for 2 weeks after the withdrawal of TCA, dose-dependently and significantly decreased the total length of erosions. The indicators of atrophic gastritis, i.e., reduced mucosal thickness and reduction in the number of parietal cells, were improved dose-dependently by the administration of this agent. Egualen sodium also reduced the inflammatory cell infiltration and the proliferation of collagenous fiber in the gastric mucosa in a dose-dependent manner. The reduced staining of neutral gastric mucus was improved by a high dose (100 mg/kg) of egualen sodium. The therapeutic effects of egualen sodium on experimental gastritis were superior to those of sofalcone and sodium guaiazulene 3-sulfonate. These results suggest that egualen sodium may be a promising agent for the treatment of erosive and atrophic gastritis. PMID:9027640

    Full Text Available Abstract Background We describe a rare case of diffuse macroscopic discoloration and chemical gastritis due to chronic bromazepam intake. The chemical composition of pharmaceuticals has to be considered at endoscopy and it is evident that some chemical substances damage the epithelial tissue and lead to clinical symptoms. Case Presentation Endoscopy was performed in an 82-year-old patient due to gastroesophageal reflux symptoms and epigastric pain. Gastroscopy showed a hiatal hernia and a scarred duodenal bulb. More striking was the yellow-brownish discoloration of the gastric and the duodenal mucosa. The gastric antrum and the duodenal bulb showed local discoloration that could not be rinsed off. The medical history indicated that bromazepam (6 mg had been used daily as a sleeping aid in the previous two years. The histopathological findings showed appearances of chemical gastritis. Within the lamina propria and on the epithelial surface there were granules. There was no foreign body reaction to these granules. Corpus mucosa showed a mild chronic gastritis. Conclusions If discoloration of the mucosa at endoscopy is seen, a careful drug history must be sought. This is the first case in literature that shows a chemical gastritis after bromazepam intake.

    Collagenous gastritis is a rare disorder, with only 8 cases reported in the literature, 2 in children and 6 in adults. We report an additional case of collagenous gastritis in a 42-year-old man with celiac disease. A thickened (>10 microm) subepithelial collagen band with entrapped capillaries, fibroblasts, and inflammatory cells was seen in the stomach, associated with lymphocytic gastritis. The duodenal mucosa showed severe villous atrophy but no subepithelial collagen deposition. No evidence of lymphocytic or collagenous colitis was found in the colon. The patient became symptom-free on a gluten exclusion diet and showed partial improvement of histopathologic findings after 3 months. Collagenous gastritis is a rare disease, but a wider recognition of its histopathologic features and clinical associations may bring more cases to light and provide additional clues in determining its etiology and pathogenesis.

    AIM: To evaluate the histological features of gastric mucosa, including Helicobacter pylori infection in patients with early gastric cancer and endoscopically found superficial gastritis, gastric erosion, erosive gastritis,gastric ulcer.METHODS: The biopsy specimens were taken from the antrum, corpus and upper angulus of all the patients.Giemsa staining, improved toluidine-blue staining, and H pylori-specific antibody immune staining were performed as appropriate for the histological diagnosis of H pylori infection. Hematoxylin-eosin staining was used for the histological diagnosis of gastric mucosa inflammation, gastric glandular atrophy and intestinal metaplasia and scored into four grades according to the Updated Sydney System.RESULTS: The overall prevalence of H pylori infection in superficial gastritis was 28.7%, in erosive gastritis 57.7%,in gastric erosion 63.3%, in gastric ulcer 80.8%, in early gastric cancer 52.4%. There was significant difference (P<0.05), except for the difference between early gastric cancer and erosive gastritis. H pylori infection rate in antrum, corpus, angulus of patients with superficial gastritis was 25.9%, 26.2%, 25.2%, respectively; in patients with erosive gastritis 46.9%, 53.5%, 49.0%,respectively; in patients with gastric erosion 52.4%, 61.5%,52.4%, respectively; in patients with gastric ulcer 52.4%,61.5%, 52.4%, respectively; in patients with early gastric cancer 35.0%, 50.7%, 34.6%, respectively. No significant difference was found among the different site biopsies in superficial gastritis, but in the other diseases the detected rates were higher in corpus biopsy (P<0.05). The grades of mononuclear cell infiltration and polymorphonuclear cell infiltration, in early gastric cancer patients, were significantly higher than that in superficial gastritis patients, lower than that in gastric erosion and gastric ulcer patients (P<0.01);however, there was no significant difference compared with erosive gastritis.

    Collagenous colitis belongs to the group of microscopic colitis. The aetiology and pathogenesis are unknown but different pathogenic hypothesis, autoimmune, infectious, alimentary and medicinal being are advanced, the last one being the most frequent aetiology. The collagenous gastritis is a rare entity and its association with collagenous colitis was exceptionally reported, only six cases being published. We report the seventh case of collagenous gastritis, ileitis and colitis in a 75-year-old woman with chronic diarrhea and important weight loss. This thickened subepithelial collagen band was appeared in an autoimmune injury context with antecedent of Hashimoto's thyroiditis and probably chronic atrophic Biermer's gastritis. The clinical and histological evolution was favourable with budesonide. PMID:20637552

    2013-01-01

    Full Text Available Emphysematous gastritis is a rare variant of phlegmonous gastritis due to invasion of stomach wall by gas-forming bacteria. It is characterised by abnormal presence of gas in the stomach by imaging, in association with clinical sepsis. Patients suffering from this condition usually present with an underlying pathology. We are reporting a middle-aged Chinese male with hepatitis B virus related hepatocellular carcinoma. He underwent partial hepatectomy and was diagnosed with emphysematous gastritis 4 days after index operation. Emergency laparotomy, including upper endoscopy, was performed. He was managed with antibiotics and discharged 18 days after second operation. This paper shows a review of the literature about the disease, with particular attention to pathology, clinical features, and management.

    2001-07-01

    A 74-year-old woman was investigated for abdominal pain and diarrhea. Endoscopic examinations including biopsies of the stomach and colon demonstrated the typical subepithelial deposits characteristic of collagenous gastritis and collagenous colitis. Histochemical and ultrastructural methods confirmed the presence of collagen in the subepithelial deposits. The topographic distribution of these collagen deposits and their relationship to the inflammatory process in the stomach were then defined by endoscopic mapping and multiple site biopsies of the mucosa in the gastric body and antrum. These studies indicate that collagenous gastritis not only is distinctive, but also is a far more extensive and diffuse inflammatory process than has previously been appreciated. PMID:11493952

    Full Text Available Collagenous gastritis is a rare entity of unknown etiology characterized histologically by the presence of a thick subepithelial collagen band associated with an inflammatory infiltrate of gastric mucosa. A 40-year-old male presented with a history of chronic intermittent abdominal pain for about 6 months. Physical examination was unremarkable, and biological tests were within normal range. The patient underwent esophagogastroduodenoscopy and colonoscopy which showed a nodular mucosa of the stomach. Biopsies of the duodenum and colon were unremarkable. However, biopsies of the gastric fundus revealed a mild chronic gastritis characterized by lymphocytic and plasma cell infiltration of deep mucosa, without lymphoid follicle formation or active inflammation. No microorganisms were identified on routine hematoxylin and eosin or Giemsa-stained sections. Subepithelial collagen in the gastric biopsies was thickened and showed entrapped capillaries. Subepithelial collagen was highlighted by Masson's trichrome staining and was negative for amyloid by Congo Red. In the areas containing thickened collagen, there were no intraepithelial lymphocytes. The final pathological diagnosis was collagenous gastritis. Collagenous gastritis is an extremely rare disease, but it is important to recognize its characteristic endoscopic and pathologic findings to make a correct diagnosis. Specific therapy for this rare entity has not yet been established. [J Interdiscipl Histopathol 2015; 3(2.000: 68-70

    The discovery of Helicobacter pylori as the cause of gastritis and peptic ulcers ushered in the modern era of research into gastritis and into acid-peptic diseases and rekindled interest in the role of ascorbic acid in the pathophysiology and treatment of gastritis and peptic ulcer disease. Here, we review historic and modern studies on ascorbic acid and gastric diseases with an emphasis on H. pylori gastritis and its sequelae. The relationship of ascorbic acid and gastritis and peptic ulcer and its complications was extensively studied during the 1930s through the 1950s. Much of this extensive literature has been effectively "lost." Ascorbic acid deficiency was associated with all forms of gastritis (e.g., autoimmune, chemical, and infectious) due in varying degrees to insufficient intake, increased metabolic requirements, and destruction within the GI tract. Importantly, gastritis-associated abnormalities in gastric ascorbic acid metabolism are reversed by H. pylori-eradication and potentially worsened by proton pump inhibitor therapy. Diets rich in naturally occurring ascorbic acid are associated with protection of the gastric corpus from atrophy and a reduction in the incidence of gastric cancer possibly through the ability of ascorbic acid to reduce oxidative damage to the gastric mucosa by scavenging carcinogenic N-nitroso compounds and free radicals and attenuating the H. pylori-induced inflammatory cascade. Ascorbic acid supplementation was possibly associated with a decreased incidence of bleeding from peptic ulcer disease. Pharmacologic doses of ascorbic acid also may improve the effectiveness of H. pylori-eradication therapy. Occasionally, looking back can help plot the way forward. PMID:22543844

    2001-11-01

    This report reviews the literature pertaining to collagenous gastritis and describes the clinicopathologic evolution of this disease in a patient during a 12-year period. We examined 109 biopsy specimens of gastric mucosa from 19 different endoscopic procedures for the severity and distribution of collagenous gastritis in a single patient. Assessments were undertaken for the presence of endocrine and gastrin cell hyperplasias and dysplastic epithelial changes. Relative to biopsy specimens from age- and sex-matched control subjects, the patient's biopsy specimens showed a significantly lower number of antral gastrin cells, along with a significant corpus endocrine cell hyperplasia, suggesting an increased risk of endocrine neoplasia. Gastric corpus biopsy specimens revealed an active, chronic gastritis, subepithelial collagen deposition, smooth muscle hyperplasia, and mild to moderate glandular atrophy. Additional findings of intestinal metaplasia and reactive epithelial changes indeterminate for dysplasia raise concerns about the potential for adenocarcinoma. PMID:11710694

    Emphysematous gastritis is a rare form of gastritis that results from infection of the stomach wall by gas-forming organisms. Diagnosis of this commonly fatal condition rests on radiological demonstration of gas within the stomach wall. This can be observed on plain radiographs or CT scans of the abdomen. Only by prompt diagnosis and treatment can mortality be avoided. A new case of empysematous gastritis, diagnosed on CT scan by the demonstration of both intramural and portal venous gas, is presented and the literature is reviewed.

    1996-03-01

    Collagenous sprue and collagenous colitis are two well-recognized idiopathic enteritides whose defining histologic attribute is fibrous thickening of the subepithelial basement membrane. Analogous changes in gastric mucosa seem to be quite rare. The term "collagenous gastritis" was recently applied for the first time to an isolated case of refractory gastritis in which distinctive subepithelial gastric fibrosis was noted. We report an additional case of this entity in a 35-year-old woman with refractory dyspepsia. In contrast to the earlier case of collagenous gastritis, our patient also had lymphocytic colitis, a type of colitis associated with watery diarrhea. Collagenous gastritis appears to be a distinct clinicopathologic entity, the histologic changes of which should be sought in patients with unexplained dyspepsia. Increased awareness of this condition and its possible clinical correlates may provide clues to its etiology and pathogenesis. PMID:8742654

In the latter group, CG is frequently associated with collagenous colitis and/or coeliac disease. This case concerns a 15-year-old boy with a bleeding ulcer. The biopsies from corpus ventriculi showed a thickened subepithelial collagen band (> 10 micrometres), and the patient was diagnosed with CG. Ulcers are rarely linked to CG. CG should be considered when ulcers are found in children and young adults. PMID:22713227

    Collagenous gastritis is an exceptional entity with eight cases documented to date characterized by the presence of a thick subepithelial collagen band associated with an inflammatory infiltrate of the gastric mucosa. The aim of our study was to describe the clinical and histologic characteristics of six new cases of collagenous gastritis. All cases showed a subepithelial collagen band that averaged 30 microm but often measured up to 120 microm. This finding was almost always accompanied by mixed chronic inflammation in the lamina propria and by surface epithelial damage of varying severity. Our study seems to delineate two subsets in patients with collagenous gastritis: 1) collagenous gastritis occurring in children and young adults presenting with severe anemia, a nodular pattern on endoscopy, and a disease limited to the gastric mucosa without evidence of colonic involvement, and 2) collagenous gastritis associated with collagenous colitis occurring in adult patients presenting with chronic watery diarrhea. These findings highlight the fact that subepithelial collagen deposition may be a generalized disease affecting the entire gastrointestinal tract. PMID:11688577

    Full Text Available Gastric lipase is one of the prepancreatic lipases found in some mammalian species and in humans. Our knowledge of the hormonal regulation of gastric lipase secretion in children and adolescents is still very limited. The aim of this study was to compare the activity of human gastric lipase (HGL in gastric juice in healthy adolescents and in patients with gastritis. The adolescents were allocated to three groups: the first including patients with Helicobacter pylori gastritis (HPG; n = 10, the second including patients with superficial gastritis caused by pathogens other than H. pylori (non-HPG; n = 14 and the control group including healthy adolescents (n = 14. Activity of HGL was measured in gastric juice collected during endoscopy. Plasma concentrations of cholecystokinin (CCK, glucagon-like peptide-1 (GLP-1 and glucose-dependent insulinotropic peptide (GIP were measured in all adolescents. Activity of HGL in the non-HPG group was significantly lower than in the HPG group (p < 0.005 and the control group (p < 0.005. Mean plasma GIP levels in the control group were lower than in the non-HPG group (p < 0.003 and the HPG group (p < 0.01. We conclude that the regulation of HGL secretion by GLP-1 and CCK is altered in patients with gastritis. Moreover, GIP is a potent controller of HGL activity, both in healthy subjects and in patients with gastritis.

    Full Text Available Problem statement: Speech corpus is one of the major components in corpus-based synthesis. The quality and coverage in speech corpus will affect the quality of synthesis speech sound. Approach: This study proposes a corpus design for Malay corpus-based speech synthesis system. This includes the study of design criteria in corpus-based speech synthesis, Malay corpus based database design and the concatenation engine in Malay corpus-based synthesis system. A set of 10 millions digital text corpuses for Malay language has been collected from Malay internet news. This text corpus had been analyzed using word frequency count to find out all high frequency words to be used for designing the sentences for speech corpus. Results: Altogether 381 sentences for speech corpus had been designed using 70% of high frequency words from 10 million text corpus. It consists of 16826 phoneme units and the total storage size is 37.6Mb. All the phone units are phonetically transcribed to preserve the phonetic context of its origin that will be used for phonetic context unit. This speech corpus had been labeled at phoneme level and used for variable length continuous phoneme based concatenation. Speech corpus is one of the major components in corpus-based synthesis. The quality and coverage in speech corpus will affect the quality of synthesized speech sound. Conclusion/Recommendation: This study has proposed a platform for designing speech corpus especially for Malay Text to Speech which can be further enhanced to support more coverage and higher naturalness of synthetic speech.

    Severe gastric complications due to radiotherapy are uncommon, in particular hemorrhagic gastritis. A high total dose and, above all, high daily fraction appear to be the main risk factors in gastric injuries. A case of hemorrhagic gastritis induced by radiotherapy requesting a total gastrectomy is reported. The patient was treated for a primary gastric non-Hodgkin's lymphoma. Hemorrhagic gastritis occurred despite a low total dose (40 Gy) and 2 Gy daily fractions. Upper gastrointestinal endoscopy and repeated biopsies are usually insufficient to exclude a tumor recurrence. Endoscopic ultrasonography may argue for a recurrence or for radiation lesions. As the conservative treatment is usually ineffective, these gastrointestinal radiation injuries ought to be treated surgically. Besides it allows to ascertain the benign nature of radiation lesions.

    AIM: To investigate the prevalence of H pylori associated corpus-predominant gastritis (CPG) or pangastritis, severe atrophy, and intestinal metaplasia (IM) in patients without any significant abnormal findings during upper GI endoscopy.METHODS: Gastric biopsies from 3548 patients were obtained during upper GI-endoscopy in a 4-year period. Two biopsies from antrum and corpus were histologically assessed according to the updated Sydney-System.Eight hundred and forty-five patients (mean age 54.8 ±2.8 years) with H pylori infection and no peptic ulcer or abnormal gross findings in the stomach were identified and analyzed according to gastritis phenotypes using different scoring systems.RESULTS: The prevalence of severe H pylori associated changes like pangastritis, CPG, IM, and severe atrophy increased with age, reaching a level of 20% in patients of the age group over 45 years. No differences in frequencies between genders were observed. The prevalence of IM had the highest increase, being 4-fold higher at the age of 65 years versus in individuals less than 45 years.CONCLUSION: The prevalence of gastritis featuring at risk for cancer development increases with age. These findings reinforce the necessity for the histological assessment, even in subjects with normal endoscopic appearance. The age-dependent increase in prevalence of severe histopathological changes in gastric mucosa, however, does not allow estimating the individual risk for gastric cancer development-only a proper follow-up can provide this information.

    AIM: To investigate the influences of bile reflux on profiles of gastric mucosal lesions in patients with dyspepsia or chronic gastritis.METHODS: A total of 49 patients diagnosed with dyspepsia and chronic gastritis underwent 24-h ambulatory andsimultaneous monitoring of intragastric bilirubin absorbance and pH values, and then they were divided into bile refluxpositive group and bile reflux negative group. Severity of pathological changes in gastric mucosa including activeinflammation, chronic inflammation, intestinal metaplasia, atrophy and dysplasia as well as Helicobacter pylori (H pylori) infection at the corpus, incisura and antrum were determined respectively according to update Sydney system criteria. The profiles of gastric mucosal lesions in the two groups were compared, and correlations between time-percentage of gastric bilirubin absorbance >0.14 and severity of gastric mucosal lesions as well as time-percentage of gastric pH >4 were analyzed respectively. RESULTS: Thirty-eight patients (21 men and 17 women, mean age 44.2 years, range 25-61 years) were found existing with bile reflux (gastric bilirubin absorbance >0.14) and 11 patients (7 men and 4 women, mean age 46.2 years,range 29-54 years) were bile reflux negative. In dyspepsia patients with bile reflux, the mucosal lesions such as active inflammation, chronic inflammation, intestinal metaplasia, atrophy or H pylori infection in the whole stomach, especially in the corpus and incisura, were significantly more severe than those in dyspepsia patients without bile reflux. Moreover, the bile reflux time was well correlated with the severity of pathological changes of gastric mucosa as well as H pylori colonization in the near-end stomach, especially in the corpus region. No relevance was found between the time of bile reflux and pH >4 in gastric cavity. CONCLUSION: Bile reflux contributes a lot to mucosal lesions in the whole stomach, may facilitate H pylori colonization in the corpus region

    2007-08-01

    In this article, we report a case of collagenous gastritis in a child and review the paediatric cases reported to date. Collagenous gastritis is a rare entity, with only less than 30 cases reported so far, including 12 children, since the first description of this entity by Colletti and Trainer in 1989. This is a histological diagnosis characterised by a dramatically thickened subepithelial collagen band in the gastric mucosa associated with an inflammatory infiltrate. Children with this condition often present with epigastric pain and severe anaemia, with no evidence of extragastric involvement, in contrast to the adult patients, where chronic watery diarrhoea is the main presentation due to associated collagenous colitis. A macroscopic pattern of gastritis with nodularity of gastric mucosa, erythema and erosions are characteristic endoscopic findings in paediatric patients. Specific therapy has not been established and resolution of the abnormalities, either endoscopic or histological, has not been documented. In conclusion, collagenous gastritis is a rare entity of unknown aetiology, pathogenesis and prognosis. Gastroenterologists and pathologists need to be aware of this condition when evaluating a child with epigastric pain, anaemia and upper gastrointestinal bleeding, particularly when endoscopy reveals the nodularity of gastric mucosa. The identification, reporting and long-term follow-up of cases will shed more light on this puzzling condition. PMID:17453238

    AIM: To evaluate fecal calprotectin concentrations (FCCs) in subjects with chronic gastritis and the correlation between FCCs and gastritis activity score. METHODS: FCCs were measured in 61 patients with histological diagnosis of gastritis and in 74 healthy volunteers. Histological grading of gastritis was performed according to the updated Sydney gastritis classification. Patients were subdivided into 2 groups according to the presence/absence of an active gastritis. Patients with chronic active gastritis were divided into 3 subgroups on the basis of the activity score (mild, moderate, marked). FFCs in relation to Helicobacter pylori (H. pylori) infection and proton pump inhibitor (PPI) use were also evaluated. RESULTS: FCCs in patients with chronic active gastritis were not significantly different to FCCs either in subjects with non active gastritis or in healthy controls. Among patients with chronic active gastritis (even marked), FCCs did not significantly differ according to activity score. No significant differences in FCCs were found when considering H. pylori, as well as when considering PPI chronic use. CONCLUSION: FCCs were not significantly increased in subjects with chronic gastritis, even in those patients with a marked neutrophil infiltration. PMID:20632443

    AIM: To conduct a detailed histological study of gastritis in adult patients attending an endoscopy clinic at a Kenyan teaching and referral hospital.METHODS: Biopsy specimens from consecutive patients were examined and graded according to the Updated Sydney System for H pylori infection, chronic inflammation, neutrophil activity, glandular atrophy and intestinal metaplasia. Also documented were gastric tissue eosinophil counts and presence of lymphoid follicles.RESULTS: The rate of the graded variables, in the antrum and corpus respectively, were as follows:H pylori infection (91%, 86%), chronic inflammation (98%, 93%),neutrophil activity (91%, 86%), glandular atrophy (57%,15%) and intestinal metaplasia (11%, 2%). Lymphoid follicles were noted in 11% of cases. Duodenal and gastric ulcers were documented in 32% and 2% respectively.The mean eosinophil count was 5.9 ± 0.74 eosinophils/HPF and 9.58 ± 0.93 eosinophils/HPF in the corpus and antrum respectively. Significant association was found between the degree of H pylori colonisation with chronic inflammation, neutrophil activity and antral glandular atrophy. Biopsies from the antrum and corpus showed significant histopathological discordance for all the graded variables.H pylori negative cases were associated with recent antibiotic use.CONCLUSION: The study reaffirms that H pylori is the chief cause of gastritis in this environment. The majority of patients show a moderate to high degree of inflammation but a low degree of glandular atrophy and intestinal metaplasia. The study shows that interrelationships between the histological variables in this African population are similar to those found in other populations worldwide including non-African populations.

    2015-03-01

    Full Text Available Management of breast cancer includes systematic therapies including chemotherapy and endocrine therapy can lead to a variety of symptoms that can impair the quality of life of many breast cancer survivors. Atrophic vaginitis, caused by decreased levels of circulating estrogen to urinary and vaginal receptors, is commonly experienced by this group. Chemotherapy induced ovarian failure and endocrine therapies including aromatase inhibitors and selective estrogen receptor modulators can trigger the onset of atrophic vaginitis or exacerbate existing symptoms. Symptoms of atrophic vaginitis include vaginal dryness, dyspareunia, and irritation of genital skin, pruritus, burning, vaginal discharge, and soreness. The diagnosis of atrophic vaginitis is confirmed through patient-reported symptoms and gynecological examination of external structures, introitus, and vaginal mucosa. Lifestyle modifications can be helpful but are usually insufficient to significantly improve symptoms. Non-hormonal vaginal therapies may provide additional relief by increasing vaginal moisture and fluid. Systemic estrogen therapy is contraindicated in breast cancer survivors. Continued investigations of various treatments for atrophic vaginitis are necessary. Local estrogen-based therapies, DHEA, testosterone, and pH-balanced gels continue to be evaluated in ongoing studies. Definitive results are needed pertaining to the safety of topical estrogens in breast cancer survivors.

    Collagenous gastritis (CG) is an uncommon condition known in the pediatric age. It is characterized by the presence of subepithelial collagen bands (> 10 μm) associated with lymphoplasmacytic infiltration of the stomach's lamina propria. Symptoms manifested by patients with CG may be common with many other disorders. It typically manifests with epigastralgia, vomiting, and iron deficiency during pre-adolescence. This condition's pathophysiology remains unclear. In contrast to adults, where as...

    Brain, Oliver; Rajaguru, Chandima; Warren, Bryan; Booth, Jonathan; Travis, Simon

    2009-12-01

    Collagenous gastritis is a rare disorder first described in 1989. After encountering two cases, we decided to review the literature and evaluate the collagen band. A systematic review of PubMed and EMBASE databases was performed. Twenty-eight cases have been previously described and two patterns of presentations are identifiable: children or young adults (median age 12 years, range 2-22 years) presenting with symptoms attributable to the gastritis (anaemia and pain); and older adults (median age 52 years, range 35-77 years) presenting with loose stools, often associated with collagenous colitis or coeliac disease. Our two cases (one child and one adult) matched this pattern. Immunostaining of the collagen band for collagens II, III, IV and VI, and tenascin showed that the band in our cases was predominantly tenascin. In conclusion, collagenous gastritis is a rare entity whose presentation depends on the age of the patient. An autoimmune aetiology seems possible given its associations. Treatment is empirical. The 30 cases now reported show that the disorder can relapse or persist for years. PMID:19730387

    AIM: To compare Helicobacter pyloriinfection and gastric mucosal histological features of gastric ulcer patients with chronic gastritis patients in different age groups and from different biopsy sites.METHODS: The biopsy specimens were taken from the antrum, corpus and upper angulus of gastric ulcer and chronic gastritis patients. Giemsa staining, improved Toluidine-blue staining and H pylori-specific antibody immune staining were performed as appropriate for the histological diagnosis of H pylori infection. Hematoxylineosin staining was used for the histological diagnosis of activity of H pylori infection, mucosal inflammation,glandular atrophy and intestinal metaplasia and scored into four grades according to the Updated Sydney System.RESULTS: Total rate of H pylori infection, mucosal inflammation, activity of H pylori infection, glandular atrophy and intestinal metaplasia in 3 839 gastric ulcer patients (78.5%, 97.4%, 82.1%, 61.1% and 64.2%,respectively) were significantly higher than those in 4 102chronic gastritis patients (55.0%, 90.3%, 56.2%, 36.8%,and 37.0%, respectively, P<0.05). The rate of H pylori colonization of chronic gastritis in <30 years, 31-40 years,41-50 years, 51-60 years, 61-70 years and >70 years age groups in antrum was 33.3%, 41.7%, 53.6%, 57.3%,50.7%, 43.5%, respectively; in corpus, it was 32.6%,41.9%, 53.8%, 60.2%, 58.0%, 54.8%, respectively; in angulus, it was 32.4%, 42.1%, 51.6%, 54.5%, 49.7%,43.5%, respectively. The rate of Hpyloricolonization of gastric ulcer in <30 years, 31-40 years, 41-50 years,51-60 years, 61-70 years and >70 years age groups in antrum was 60.5%, 79.9%, 80.9%, 66.8%, 59.6%, 45.6%,respectively; in corpus, it was 59.7%, 79.6%, 83.6%,80.1%, 70.6%, 59.1%, respectively; in angulus, it was61.3%, 77.8%, 75.3%, 68.8%, 59.7%, 45.8%,respectively.

    Full Text Available Aim: to investigate the serum levels of TNF-α, IL-8, VEGF in Helicobacter pylori infection, and their association with the degrees of gastritis histopathology. Methods: a cross-sectional study was done on 80 consecutive gastritis patients admitted to endoscopy units at Adam Malik General Hospital and Permata Bunda Hospital, Medan, Indonesia from July-December 2014. The Rapid Urease test was used for the diagnosis of H. pylori infection. The severity of chronic inflammation, neutrophil infiltration, atrophy, and intestinal metaplasia were assessed. Serum samples were obtained to determine circulating TNF-α, IL-8, and VEGF. Univariate and bivariate analysis (chi square, fisher’s exact, and mann-whitney test were done using SPSS version-22. Results: there were 41.25% of 80 patients infected with Helicobacter pylori. Serum TNF-α and VEGF levels in the infected group were significantly higher compared to H. pylori negative, but there were no significant differences between serum levels of IL-8 in H. pylori positive and negative. There were significant associations between serum level of TNF-α and IL-8 with degree of chronic inflammation, and also between serum level of IL-8 and degree of neutrophil infiltration. There were significant associations between serum level of VEGF and degree of atrophy, and also between serum level of VEGF and degree of intestinal metaplasia. Conclusion: High levels of TNF-α were associated with severe degree of chronic inflammation, high levels of IL-8 associated with severe degree of chronic inflammation and neutrophil infiltration, and high levels of VEGF associated with severe degree of premalignant gastric lesion. Key words: cytokine, neoangiogenesis, Helicobacter pylori, atrophic gastritis, intestinal metaplasia.

    In this article, we propose an automatic process to build multi-lingual lexico-semantic resources. The goal of these resources is to browse semantically textual information contained in texts of different languages. This method uses a mathematical model called Atlas s\\'emantiques in order to represent the different senses of each word. It uses the linguistic relations between words to create graphs that are projected into a semantic space. These projections constitute semantic maps that denote the sense trends of each given word. This model is fed with syntactic relations between words extracted from a corpus. Therefore, the lexico-semantic resource produced describes all the words and all their meanings observed in the corpus. The sense trends are expressed by syntactic contexts, typical for a given meaning. The link between each sense trend and the utterances used to build the sense trend are also stored in an index. Thus all the instances of a word in a particular sense are linked and can be browsed easily...

    Background Spleen in Traditional Chinese Medicine (TCM) is not actually the spleen in the anatomic sense designated in western medicine because its functions basically belong to the physiological category of digestive system in modern medicine, and it represents a macroscopic concept of digestion, absorption and nutrition metabolism. Spleen deficiency syndrome refers to the clinical phenomena such as hypofunction of digestion, absorption and nutrition metabolism. By integrating TCM with modern medicine , this paper is intended to explore the pathological basis of classification of spleen deficiency in chronic gastritis.Method By means of optical microscope, scanning electron microscope (SEM), transmission electron microscope (TEM) and histochemical staining, we conducted histopathological and subcellular ultrastructural (nuclei and mitochondrial) analysis of gastric mucosa of 188 patients of spleen deficiency, and that of 42 voluntary blood donors without clinical symptoms. Results The gastric mucosa of patients with spleen Qi deficiency (SQD) and spleen yang deficiency (SyangD) could either be affected by organic lesion (type G-occurring on the basis of chronic superficial gastritis (CSG), chronic atrophic gastritis (CAG)) or unaffected (type F-chiefly belonging to functional indigestion); spleen yin deficiency (SyinD) and spleen deficiency with Qi stagnation (SDQS) both occurred on the basis of CSG and CAG; and the degree of mucosa inflammatory cells infiltration, the degree of decrease in glands propria, and the incidence of IMⅡb in CSG and CAG were more serious than those of G-SQD and G-SyangD, P<0.05-0.01.Conclusion Spleen deficiency syndrome is likely to occur on the basis of organic lesion of gastric mucosa (disease with symptoms of both CSG or CAG and spleen deficiency symptoms), as well as on the basis of inorganic lesion of gastric mucosa (nondisease with symptoms, which is, despite spleen deficiency symptoms, there is no CSG or CAG).

    Background Most of the studies on traditional Chinese medicine (TCM)‘spleen’deficiency syndrome in the recent 30 years were conducted only on the basis of single functional index, neglecting the study on the pathophysiologic internal relationship between spleen deficiency syndrome and gastric diseases in modern medicine. But it was at the subcellular molecular biological level that we explored the pathophysiologic basis of classification of spleen deficiency in chronic gastritis by detecting the bioactive substances in gastric mucosa nuclei and mitochondria. Methods By means of optical microscope, scanning electron microscope (SEM), transmission electron microscopy (TEM) and histochemical staining, we conducted histopathological, subcellular ultrastructural analysis and nuclei and mitochondrial ultrastructural analysis of gastric mucosa of 188 spleen deficiency patients and of 42 voluntary blood donors. At the same time, bioactive substances were measured by means of X-ray energy dispersive analysis system (EDAX) image analysis system, radioimmunoassay method and chemiluminescence method. Results The content of cAMP, superoxide dismutase (SOD), Zn and Cu in gastric mucosa, and the content of Zn and Cu in mitochondria decreased progressively in order of groups: healthy control (HC), spleen Qi deficiency without organic lesion (F-SQD), spleen Yang deficiency without organic lesion (F-SyangD), disease without symptoms group, spleen Qi deficiency with organic lesion (G-SQD), spleen Yang deficiency with organic lesion (G-SyangD), spleen Yin deficiency (SyinD) and spleen deficiency with Qi stagnation (SDQS), chronic spleen deficiency gastritis (CSG) and chronic atrophic gastritis (CAG); decreased in order of HC, intestinal metaplasia (IM)Ⅰa, IMⅠb, IMⅡa and IMⅡb, P<0.05. The content of DNA, Zn and Cu in nuclei progressively increased in order mentioned above, P<0.05.Conclusions The quantitative changes of gastric mucosal cAMP, SOD, Zn, Cu, of mitochondrial Zn

Although the diagnostic techniques for alimentary diseases of horses have improved significantly over the past few years, difficulties still exist in establishing the causes of a significant number of enteric diseases in this species. This problem is compounded by several agents of enteric disease also being found in the intestine of clinically normal horses, which questions the validity of the mere detection of these agents in the intestine.

  13. Towards an integrated corpus stylistics

    2015-12-01

    Full Text Available Over recent years, the use of corpora in stylistic analysis has grown in popularity. However, questions still remain over the remit of corpus stylistics, its distinction from corpus linguistics generally and its capacity to explain complex stylistic effects. This article argues in favour of an integrated corpus stylistics; that is, an approach to corpus stylistics that integrates it with other stylistic methods and analytical frameworks. I suggest that this approach is needed for two main reasons: (i it is analytically necessary in order to fully explain stylistic effects in texts, and (ii integrating corpus methods with other stylistic tools is what will distinguish corpus stylistics from corpus linguistics. My argument is supported by reference to examples from Mark Haddon’s no vel The Curious Incident of the Dog in the Night-time and the HBO TV series Deadwood. Both these examples rely for their explanation on a combination of corpus stylistic analytical techniques and other stylistic methods of analysis.

  14. [Corpus Hermeticum in history].

    The originator and founder of hermetism was the mythical Hermes Trismegistos, a deity of the syncretic Hellenistic religion that came into being through the identification of the Greek god Hermes with the Egyptian god Thot. In later Hellenistsic times various hermetic writers considered Hermes Trismegistos to have been a historical personage, a king, prophet and philosopher (physician), as well as author of many widely disseminated writings that made up the so-called Corpus Hermeticum (eighteen separate treatises from the 2nd-4th centuries AD) and the so-called Emerald Table (Tabula Smaragdina). The Corpus Hermeticum is a collection of treatises of a philosophical, religious, theological as well as theosophical nature. The collection played an important role in the development of the philosophy of alchemy and hermetism, and formed the basis for an alchemist philosophy of nature. There are currently two views among scholars on the origins of hermetism. According to one, hermetism derived directly from Egypt, while according to the other it orginated in Greece. In the years 1945-46 a number of hermetic texts forming part of the now famous gnostic "library" were discovered in Nag-Hammadi (Chenosboskion) in Upper Egypt. The Coptic texts from Nag-Hammadi date from the middle of the 4th century AD, and according to experts are translations from the Greek. Some authors (R. Reitzenstein and T. Zieliński) have suggested that along with the appearance in Egypt of the Hermetic Books, attributed to Hermes Trismegistos, there also appeared a new god in Egypt, Poimandres, and a new religion was established, hermetism, which competed for influence with Christianity. The present article discusses the main of the hermetic treatises, including Poimandres, which contains an account of the creation of the world. The article also discusses the reasons for the decline of hermetism as a religion and stresses that in spite of this decline the doctrine managed to survive in the form of

    2002-01-01

    The gastroesophageal reflux disease (GORD) is frequent and causes by retrograde flow of the gastric content through incompetent gastroesophageal junction. Epidemiological studies have proved that GORD is associated with hearburn in high prevalence. In western countries several studies reported that 20-40% of adult population experience heartburn symptoms at least once in the year, approximately 10% have symptoms weekly and 5% daily. Esophagitis was objectively defined as a mucosal damage and it was endoscopically verificated in 25% of patients. Indeed, GORD symptoms and esophagitis are in poor correlation and less than half of patients with heartburn symptoms had esophagitis on endoscopy. From 1989, Savary Monniér and Metaplasia-Ulcer-Stricture-Erosion (MUSE) endoscopically classification is in use. From 1994, LA (Los Angeles) classification of reflux disease is also in use by endoscopists. During its life cycle, gastric mucosa is exposed to different harmful agents and its response is restitution "ad integrum" on the beginning and at the end of process. First line defence is mucuse barrier which prevent contact between epithelial cell and possible irritant. Important role in mucuse layer plays prostaglandins. After several classification systems previously used, in 1991 Price introduced Sydney system gradation and gastritis classification. Pointing out importance of topographical differences in gastritis distribution, system has introduced 5 histological variations in its Morphological section: chronic inflammation, neutrophylic activity, glandular atrophy, intestinal metaplasy and H. pylori colonisation, with 4 points grading.

    Full Text Available Collagenous gastritis (CG is an uncommon condition known in the pediatric age. It is characterized by the presence of subepithelial collagen bands (> 10 μm associated with lymphoplasmacytic infiltration of the stomach's lamina propria. Symptoms manifested by patients with CG may be common with many other disorders. It typically manifests with epigastralgia, vomiting, and iron deficiency during pre-adolescence. This condition's pathophysiology remains unclear. In contrast to adults, where association with collagenous colitis and other autoimmune conditions is more common, pediatric involvement is usually confined to the stomach. Drugs of choice include proton pump inhibitors and corticoids. A case is reported of a 12-year-old girl with abdominal pain and ferritin deficiency who was diagnosed with CG based on gastric biopsy and experienced a favorable outcome.

    Collagenous gastritis is a rare histopathological disorder of unknown origin, characterized by a subepithelial collagen deposit greater than 10 microm thick, associated with an inflammatory infiltrate of the gastric mucosa. This report describes a second pediatric case of collagenous gastritis, revealed by severe anemia caused by gastric bleeding, as was the first case. Unlike the adult cases of collagenous gastritis, lesions were limited to the stomach, and remained unchanged on six series of biopsies taken during a 30 month follow-up, despite treatment with omeprazole, sucralfate and corticosteroids. An immunohistochemical study showed signs of local immune activation on all biopsy specimens, including overexpression of HLA-DR by epithelial cells, increased numbers of CD3+ intraepithelial lymphocytes, and CD25+ cells in the lamina propria. Although the cause of the disease remains unclear, our findings suggest that the histopathological lesions of collagenous gastritis may result from a local immune process. PMID:9712433

    Collagenous gastritis is rare; there are only four previous case reports. Histologic features seem to overlap with the other "collagenous enterocolitides"; however, pathologic criteria are not yet established for the diagnosis of collagenous gastritis. We describe an additional case of ostensible collagenous gastritis in a patient who initially presented with celiac sprue and subsequently developed colonic manifestations of mucosal ulcerative colitis. Endoscopic biopsies of the stomach revealed deposition of patchy, very thick bandlike subepithelial collagen in gastric antral mucosa, focal superficial epithelial degeneration, numerous intraepithelial lymphocytes, and a dense lamina propria lymphoplasmacytic infiltrate. Image analysis evaluation of gastric antral biopsies demonstrated a mean thickness of subepithelial collagen of 27.07 micron. Morphologic comparison was made with age-matched control groups of 10 patients who had normal gastric mucosal biopsies and 10 patients who had "chronic" gastritis, which revealed mean subepithelial collagen measures of 1.37 micron and 1.19 micron, respectively. We compared these morphologic findings with those of all previous case reports of collagenous gastritis and propose a pathologic definition based on the limited combined data. It seems that subepithelial collagen is dramatically thickened in reported cases of collagenous gastritis, with a cumulative mean measure of 36.9 micron. It is also apparent from this and previous reports that the thickened subepithelial collagen is accompanied by a chronic or chronic active gastritis and sometimes intraepithelial lymphocytes and surface epithelial damage. Recently described associations of lymphocytic gastritis, sprue, and lymphocytic colitis as well as collagenous and lymphocytic colitis suggest a common pathogenesis that empirically may include collagenous gastritis in the same disease spectrum. We propose that collagenous gastritis can be confidently identified by using

  12. DEVELOPING SOFTWARE FOR CORPUS RESEARCH

    Directory of Open Access Journals (Sweden)

    Oliver Mason

    2008-06-01

    Full Text Available Despite the central role of the computer in corpus research, programming is generally not seen as a core skill within corpus linguistics. As a consequence, limitations in software for text and corpus analysis slow down the progress of research while analysts often have to rely on third party software or even manual data analysis if no suitable software is available. Apart from software itself, data formats are also of great importance for text processing. But again, many practitioners are not very aware of the options available to them, and thus idiosyncratic text formats often make sharing of resources difficult if not impossible. This article discusses some issues relating to both data and processing which should aid researchers to become more aware of the choices available to them when it comes to using computers in linguistic research. It also describes an easy way towards automating some common text processing tasks that can easily be acquired without knowledge of actual computer programming.

    Here, we report on a case of acute phlegmonous gastritis (PG) complicated by delayed perforation. A 51-year-old woman presented with severe abdominal pain and septic shock symptoms. A computed tomography scan showed diffuse thickening of the gastric wall and distention with peritoneal fluid. Although we did not find definite evidence of free air on the computed tomography (CT) scan, the patient's clinical condition suggested diffuse peritonitis requiring surgical intervention. Exploratory laparotomy revealed a thickened gastric wall with suppurative intraperitoneal fluid in which Streptococcus pyogenes grew. There was no evidence of gastric or duodenal perforation. No further operation was performed at that time. The patient was conservatively treated with antibiotics and proton pump inhibitor, and her condition improved. However, she experienced abdominal and flank pain again on postoperative day 10. CT and esophagogastroduodenoscopy showed a large gastric ulcer with perforation. Unfortunately, although the CT showed further improvement in the thickening of the stomach and the mucosal defect, the patient's condition did not recover until a week later, and an esophagogastroduodenoscopy taken on postoperative day 30 showed suspected gastric submucosal dissection. We performed total gastrectomy as a second operation, and the patient recovered without major complications. A pathological examination revealed a multifocal ulceration and necrosis from the mucosa to the serosa with perforation.

    AIM: To establish an experimental animal model of chronic gastritis in a short term and to investigate the effects of several potential inflammation-inducing factors on rat gastric mucosa.METHODS: Twenty-four healthy, male SD rats were treated with intragastric administration of 600 mL/L alcohol, 20mmol/L sodium deoxycholate and 0.5 g/L ammonia (factor A), forage containing low levels of vitamins (factor B), and/or indomethacin (factor C), according to an L8(27)orthogonal design. After 12 wk, gastric antral and body mucosae were pathologically examined.RESULTS: Chronic gastritis model was successfully induced in rats treated with factor A for 12 wk. After the treatment of animals, the gastric mucosal inflammation was significantly different from that in controls, and the number of pyloric glands at antrum and parietal cells at body were obviously reduced (P<0.01). Indomethacin induced gastritis but without atrophy, and short-term vitamin deficiency failed to induce chronic gastritis and gastric atrophy, In addition,indomethacin and vitamin deficiency had no synergistic effect in inducing gastritis with the factor A. No atypical hyperplasia and intestinal metaplasia in the gastric antrum and body were observed in all rats studied.CONCLUSION: Combined intragastric administration of 600 mL/L alcohol, 20 mmol/L sodium deoxycholate and 0.5 g/L ammonia induces chronic gastritis and gastric atrophy in rats. Indomethacin induces chronic gastritis only.The long-term roles of these factors in gastric inflammation and carcinogenesis need to be further elucidated.

  15. Paradigm Shift in the Management of the Atrophic Posterior Maxilla

    Directory of Open Access Journals (Sweden)

    Rabah Nedir

    2014-01-01

    Full Text Available When the posterior maxilla is atrophic, the reference standard of care would be to perform sinus augmentation with an autologous bone graft through the lateral approach and delayed implant placement. However, placement of short implants with the osteotome sinus floor elevation technique and without graft can be proposed for an efficient treatment of clinical cases with a maxillary residual bone height of 4 to 8 mm. The use of grafting material is recommended only when the residual bone height is ≤4 mm. Indications of the lateral sinus floor elevation are limited to cases with a residual bone height ≤ 2 mm and fused corticals, uncompleted healing of the edentulous site, and absence of flat cortical bone crest or when the patient wishes to wear a removable prosthesis during the healing period. The presented case report illustrates osteotome sinus floor elevation with and without grafting and simultaneous implant placement in extreme conditions: atrophic maxilla, short implant placement, reduced healing time, and single crown rehabilitation. After 6 years, all placed implants were functional with an endosinus bone gain.

    AIM To investigate the roles of the neuropeptides vasoactive intestinal peptide (VIP), substance P (SP), and calcitonin gene-related peptide (CGRP) in chronic gastritis and duodenitis in children. METHODS Biopsy samples from the gastric and duodenal mucosa of 52 patients and 30 control subjects were obtained. Samples were taken for pathological examination, immunohistochemical staining, enzyme activity measurements and quantitative measurements of tissue peptide levels. RESULTS We observed differential effects of the disease on peptide levels, which were somewhat different from previously reported changes in chronic gastritis in adults. Specifically, SP was increased and CGRP and VIP were decreased in patients with gastritis. The changes were more prominent at sites where gastritis was severe, but significant changes were also observed in neighboring areas where gastritis was less severe. Furthermore, the degree of changes was correlated with the pathological grade of the disease. The expression of CD10, the enzyme primarily involved in SP hydrolysis, was also decreased in patients with duodenitis. CONCLUSION Based on these findings, we propose that decreased levels of VIP and CGRP and increased levels of SP contribute to pathological changes in gastric mucosa. Hence, new treatments targeting these molecules may have therapeutic and preventive effects. PMID:27729741

    Russell body gastritis is an unusual form of chronic gas-tritis characterized by the permeation of lamina propria by numerous plasma cells with eosinophilic cytoplasmic inclusions. Very few cases have been reported in the lit-erature; the majority of which have shown Helicobacter Pylori (H. pylori) infection, thus suggesting a correlation between plasma cell presence and antigenic stimulation by H. pylori. We present a case of Russell body gastritis in a 78-year-old woman who was undergoing esophago-gastroduodenoscopy for epigastric pain. Gastric biopsy of the gastroesophageal junction showed the presence of cells with periodic acid-Schiff-positive hyaline pink bodies. Giemsa staining for H. pylori infection was nega-tive, as well as immunohistochemical detection. The cells with eosinophilic inclusions stained positive for CD138, CD79a, and κ and lambda light chains, which confirmed plasma cell origin. In particular, κ and lambda light chains showed a polyclonal origin and the patient was negative for immunological dyscrasia. The histologi-cal observations were confirmed by ultrastructural ex-amination. The cases reported in the literature associated with H. pylori infection have shown regression of plasma cells after eradication of H. pylori. Nothing is known about the progression of H. pylori-negative cases. The unusual morphological appearance of this type of chron-ic gastritis should not be misinterpreted during routine examination, and it should be distinguished from other common forms of chronic gastritis. It is mandatory to exclude neoplastic diseases such as gastric carcinoma, lymphoma and plasmocytoma by immunohistochemistry and electron microscopy, which can help with differential diagnosis. The long-term effects of plasma cells hyper-activation are still unknown, because cases of gastric tu-mor that originated in patients affected by Russell body gastritis have not been described in the literature. We are of the opinion that these patients should be

    Collagenous gastritis is a rare gastrointestinal disorder characterized in pediatrics by abdominal pain and anemia. The literature divides collagenous gastritis into distinct pediatric-onset and adult-onset phenotypes. As opposed to pediatric form, the adult form is associated with collagenous colitis and presents clinically with voluminous non-bloody diarrhea. There are over 25 case reports of collagenous gastritis of which 10 are pediatric cases. We present two cases of pediatric onset collagenous gastritis: one with a classic pediatric presentation, the other with findings typical of adult-onset disease. This is the first report of the adult-onset phenotype collagenous gastritis in a pediatric patient. PMID:19829984

  2. Histological Features and Biocompatibility of Bone and Soft Tissue Substitutes in the Atrophic Alveolar Ridge Reconstruction

    Full Text Available The reconstruction of the atrophic alveolar ridges for implant placement is today a common procedure in dentistry daily practice. The surgical reconstruction provides for the optimization of the supporting bone for the implants and a restoration of the amount of keratinized gingiva for esthetic and functional reasons. In the past, tissue regeneration has been performed with autogenous bone and free gingival or connective tissue grafts. Nowadays, bone substitutes and specific collagen matrix allow for a complete restoration of the atrophic ridge without invasive harvesting procedures. A maxillary reconstruction of an atrophic ridge by means of tissue substitutes and its histological features are then presented.

    Because the presence or absence of H pylori infection has important implications for therapeutic decisions based on histological assessment, the reproducibility of Sydney system is important. The study was designed to test the reproducibility of features of Helicobacter pylori gastritis,using the updated Sydney classification.METHODS: Gastric biopsies of 40 randomly selected cases of Hpylori gastritis were scored semiquantitatively by three pathologists. Variables analysed included chronic inflammation,inflammatory activity, atrophy, intestinal metaplasia, H pylori,surface epithelial damage. Κ values below 0.5 represented poor, those between 0.5 and 0.75 good and values over 0.75excellent interobserver agreement.RESULTS: The best interobserver agreement (κ=0.62) was present for intestinal metaplasia. The agreement was the poorest for evaluating atrophy (κ=0.31).CONCLUSION: Although the results of this study were in accordance with some previous studies, an excellent agreement could not be reached for any features of H pylori gastritis. This low degree of concordance is assumed to be due to the personal evaluation differences in grading the features, the lack of standardized diagnostic criteria, and the ignorance to reach a consensus about the methods to be used in grading the features of H pylori gastritis before initiating the study.

    AIM: To investigate the clinicopathological factors underlying the ethnic differences of Helicobacter pylori gastritis and cancer.METHODS: We analyzed clinicopathological parameters of gastric biopsies having H pylori infection that were randomly selected from different ethnic populations including 147 Americans, 149 Japanese, and 181 Koreans.RESULTS: Males were predominant in Japanese and Korean populations (77.9 and 67.4% respectively) in comparison with Americans (48.3%) (P<0.001). H pylori gastritis in Koreans and Japanese was characterized by the predominant antral involvement. In the antrum,neutrophilic infiltration into the proliferative zone of pit, i,e.acute foveolitis, was more frequent in Koreans (82%) than in Japanese (71%) (P<0.05) and Americans (61%) (P<0.001).Interstitial neutrophilic infiltration, intestinal metaplasia and atrophy were also frequent in Koreans and Japanese. In the body, the prevalence of acute foveolitis was not significantly different among the populations while chronic interstitial inflammation and lymphoid follicles were more pronounced in the body of Americans than in the body of others (P<0.01).CONCLUSION: The male-, and antrum-predominant Hpylori gastritis in Koreans and Japanese is compatible with the pattern of sex and topographical distribution of gastric cancer incidence. Our data suggest that persistent acute foveolitis at the proliferative zone is a crucial step in the gastric carcinogenesis.

  9. Biological markers in Helicobacter pylori-associated gastritis and carcinoma: the value of a scoring system

    International Nuclear Information System (INIS)

    Helicobacter pylori-associated gastritis has been linked to the pathogenesis of gastric adenocarcinoma (GA), especially when assciated with intestinal metaplasia (IM) and atypia/dysplasia (A/D). We examined p53 expression, ploidy and proliferative activity and assessed H.pylori infection in relationship to IM and A/Din case of gastritis not associated with GA and in cases of GA. We examined 53 gastric biopsies from patients with gastritis not associated with GA, including patients with IM and/or A/D (n=35) and with gastritis associated with IM and/or A/D (n=21). Thirty-six distal gastrectomy specimens from patients with GA constituted a third group of patients. A scoring system that encompassed the presence or absence of H.Pylori, degree of gastritis, IM and/or A/D, p53, MIB-1prolefarative index (MPI) and ploidy was estimated in the cases of gastritis and in cancer associated mucosa (CAM) and the adenocarcinoma from patients withGA. Patients with GA had a higher median age than those with gastritis without IM and more were males (ratio 2.2:1). H.pylori was detected in 75% (40/53) of gastritis specimen and in 55% (20/36) of GA cases. There was a statistically significant difference between the incidence of gastritis without IM and/or A/D and CAM (p=0.01). p53 expression was seen in 67% of the cases (14/21) of gastritis with IM and/or A/D and only in 5% (2 cases ) of gastritis without IM (p=0.0005). A statistically significant difference in MPI was seen between CAM and GA (p=0.01) and gastritis without IM and/or A/D and gastritis with IM(p=0.004). Cases of gastritis without IM and/or or A/D has a median score of 8 while cases of gastritis with IM and/or A/D had a median score of 12 (p=0.0003). CAM had a median score of 13, which was significantly different than gastritis without IM and/or A/D(p=0.0003) The presence of IM and/or A/D can be used in H.pylori -associated gastritis as as starting point to further investigate high risk lesions.

    AIM: To conduct a retrospective study to determine the risk factors for development of metaplastic gastritis in Korean population.METHODS: The database of 113449 subjects who underwent a gastroscopy for the purpose of a regular check-up at center for health promotion, Samsung medical center during 5 years was collected and retrospectively analyzed. Among them, 5847 subjects who had endoscopically diagnosed as a metaplastic gastritis or 10076 normal as well as answered to questionnaire were included for present study. The subjects were divided into 2 groups; Group Ⅰ, normal and Group Ⅱ, metaplastic gastritis. Age, gender, Helicobacter pylori(H pylori) seropositivity, body mass index (BMI),family history of cancer, smoking, alcohol consumption,total daily calories, folate and salt intake and dietary habit (out-eating, overeating, irregular eating) were retrieved from questionnaire or electronic medical record and compared between group Ⅰ and group Ⅱ.RESULTS: The prevalence of group Ⅱ was 11%(13578/113449) increasing its prevalence with age(P= 0.000). But, there was no significant association between 2 groups in BMI, family history of cancer,alcohol consumption, total daily calories, folate and salt intake and dietary habit (out-eating, overeating, irregular eating). Old age (P=0.000), male gender (P=0.000),H pylori seropositivity (P= 0.010) and current smoker (P= 0.000) were significantly more common in group Ⅱ at multiple logistic regression model.CONCLUSION: Our data suggested that old age, male gender,Hpyloriseropositivity and smoking were risk factors for metaplastic gastritis, precancerous lesion of gastric cancer.

    Directory of Open Access Journals (Sweden)

    Theodoridis Athanasios

    2013-01-01

    Full Text Available Abstract Definition of the disease Malignant atrophic papulosis (MAP, described independently by Köhlmeier and Degos et al., is a rare, chronic, thrombo-obliterative vasculopathy characterized by papular skin lesions with central porcelain-white atrophy and surrounding teleangiectatic rim. Epidemiology Less than 200 cases have been described in the literature. The first manifestation of MAP usually occurs between the 20th and 50th year of life. Clinical description The cutaneous clinical picture is almost pathognomonic. The histology is not consistent but in most cases it shows a wedge-shaped connective tissue necrosis in the deep corium due to a thrombotic occlusion of the small arteries. In the systemic variant, manifestations mostly occur at the intestine and central nervous system. Etiology The etiopathogenesis of the disease remains unknown, a genetic predisposition may occur. Vasculitis, coagulopathy or primary dysfunction of the endothelial cells have been implicated. Diagnostic methods Diagnosis is only based on the characteristic skin lesions. Differrential diagnosis It depends on the clinical presentation of MAP, but systemic lupus erythematosus and other connective tissue diseases need to be considered. Management No effective treatment exists for the systemic manifestations, while compounds that facilitate blood perfusion have achieved a partial regression of the skin lesions in single cases. Prognosis An apparently idiopathic, monosymptomatic, cutaneous, benign variant and a progressive, visceral one with approx. 50% lethality within 2–3 years have been reported. Systemic manifestations can develop years after the occurrence of skin lesions leading to bowel perforation and peritonitis, thrombosis of the cerebral arteries or massive intracerebral hemorrhage, meningitis, encephalitis, radiculopathy, myelitis.

    AIM: To study the value of serum biomarker tests to differentiate between patients with healthy or diseased stomach mucosa: i.e. those with Helicobacter pylori (H pylori) gastritis or atrophic gastritis, who have a high risk of gastric cancer or peptic ulcer diseases.METHODS: Among 162 Japanese outpatients, pepsinogenⅠ(PgⅠ) and Ⅱ(Pg Ⅱ) were measuredusing a conventional Japanese technique, and the European GastroPanel examination (PgⅠand Pg Ⅱ,gastrin-17 and H pylori antibodies). Gastroscopy with gastric biopsies was performed to classify the patients into those with healthy stomach mucosa, H pylori nonatrophic gastritis or atrophic gastritis. RESULTS: Pg Ⅰ and Pg Ⅱ assays with the GastroPanel and the Japanese method showed a highly significant correlation. For methodological reasons, however, serum Pg Ⅰ, but not Pg Ⅱ, was twice as high with the GastroPanel test as with the Japanese test.The biomarker assays revealed that 5% of subjects had advanced atrophic corpus gastritis which was also verified by endoscopic biopsies. GastroPanel examination revealed an additional seven patients who had either advanced atrophic gastritis limited to the antrum or antrum-predominant H pylori gastritis.When compared to the endoscopic biopsy findings,the GastroPanel examination classified the patients into groups with "healthy" or "diseased" stomach mucosa with 94% accuracy, 95% sensitivity and 93% specificity.CONCLUSION: Serum biomarker tests can be used to differentiate between subjects with healthy and diseased gastric mucosa with high accuracy.

    2009-05-01

    Collagenous gastritis (CG) characterized by the deposition of a subepithelial collagen band and accompanying inflammatory infiltrate is a rare disorder. The natural history and pathogenesis of CG remain unclear. We describe the histologic features (23 gastric, 18 duodenal, and 4 colonic biopsies) and clinical findings of an additional 12 cases. Histologic features including active or chronic inflammation, surface epithelial injury, intraepithelial lymphocytosis, intestinal metaplasia, and Helicobacter pylori, and measurement of thickness of subepithelial collagenous band were evaluated in gastric biopsies. The clinical features, endoscopic findings, and follow-up were obtained and correlated with histologic features. There was an even number of males (n=6) and females (n=6). Four patients were children/young adults, 3 of whom (75%) presented with anemia and gastric nodularity. Eight patients were adults, 6 of whom (75%) had an associated autoimmune disease (1 with Hashimoto thyroiditis and polymyositis) or other intestinal disease (3 with celiac sprue, 1 with collagenous colitis, 1 with collagenous sprue), in contrast to none in the 4 children/young adults, P=0.06. The range of subepithelial collagen thickness was 15 to 120 microm in CG. The collagenous layer showed surface epithelial injury and entrapped inflammatory cells. On presentation, the thickened collagen distribution in the antrum and body was variably patchy and diffuse. Four (33%) patients showed lymphocytic gastritis (3 within the same biopsy); one of these patients also had celiac sprue and another had collagenous sprue. Three (25%) patients had celiac sprue (2 had duodenal biopsy proven and 1 had a clinical diagnosis of celiac sprue). An additional patient had duodenal biopsies showing collagenous sprue. Four patients had follow-up biopsies during a 3 to 119-month period after the diagnosis of CG. CG persisted on the follow-up gastric biopsies in 3 (75%) of the 4 patients, and the other patient had

However, in clinical practice, there is complex and nonlinear relationship between symptoms (signs and syndrome. So we employed deep leaning and multilabel learning to construct the syndrome diagnostic model for chronic gastritis (CG in TCM. The results showed that deep learning could improve the accuracy of syndrome recognition. Moreover, the studies will provide a reference for constructing syndrome diagnostic models and guide clinical practice.

    Gastritis cystica polyposa (GCP) is an uncommon lesion that usually develops at the gastroenterostomy site. A 57 year old man visited a hospital with a complaint of melena. He did not have any surgical history or past medical history. Endoscopy was performed to evaluate the cause of melena, and a polypoid cystic mass in the stomach was found on an endoscopy and endoscopic ultrasonography. The polypoid cystic mass did not show any enhancing solid portion on a computed tomography. The gastric lesion was conclusively confirmed as GCP through endoscopic submucosal dissection. We report a rare case of GCP that occurred in an unoperated stomach.

    Full Text Available Background: medical translation has countless documentary sources; the major difficulty lies in knowing how to assess them. The corpus is the ideal tool to perform this activity in a rapid and reliable way, and to define the learning objectives based on text typology and oriented towards professional practice.Objective: to compile an electronic corpus that meets the requirements of the professional practice to perform specialized medical translation. Methods: a pedagogical research was conducted in the province of Cienfuegos. The units of analysis involved records from translators of the Provincial Medical Sciences Information Center and specialized translators in this field, who completed a questionnaire to accurately determine their information needs, conditioning the corpus design criteria. The analysis of a set of texts extracted from highly reputable sources led to the text selection and final compilation. Subsequently, the validation of the corpus as a documentary tool for teaching specialized medical translation was performed. Results: there was a concentration of translation assignments in the topics: malignant tumors, hypertension, heart disease, diabetes mellitus and pneumonias. The predominant text typologies were: evaluative and dissemination of current research, with plenty original articles and reviews. The text corpus design criteria were: unannotated, documented, specialized, monitor and comparable. Conclusions: the corpus is a useful tool to show the lexical, terminological, semantic, discursive and contextual particularities of biomedical communication. It allows defining learning objectives and translation problems. Key words: teaching; translating; medicine

    Full Text Available The Bulgarian-Polish-Russian parallel corpusThe Semantics Laboratory Team of Institute of Slavic Studies of Polish Academy of Sciences is planning to begin work on the creation of a Bulgarian-Polish-Russian parallel corpus. The three selected languages are representatives of the main groups of Slavic languages: Bulgarian represents the southern group of Slavic languages, Polish – the western group of Slavic languages, Russian – the eastern group of Slavic languages. Our project will be the first parallel corpus of these three languages. The planned corpus will be based on material, dating from one period (the 20th century and will have a synchronous nature. The project will not constitute the sum of the separate corpora of selected languages.One of the problems with creating multilingual parallel corpora are different proportions of translated texts between the selected languages, for example, Polish literature is often translated into Bulgarian, but not vice versa.Bulgarian, Russian and Polish differ typologically – Bulgarian is an analytic language, Polish and Russian are synthetic. The parallel corpus should have compatible annotation, while taking into account the characteristic features of the selected languages.We hope that the Bulgarian-Polish-Russian parallel corpus will serve as a source of linguistic material of contrastive language studies and may prove to be a big help for linguists, translators, terminologists and students of linguistics. The results of our work will be available on the Internet.

    2005-02-01

    Collagenous gastritis, a counterpart of collagenous colitis, is an extremely rare disorder. The first case of collagenous gastritis in a Korean boy in his pre-teens who had been receiving treatment for refractory iron deficiency anemia has been reported. The patient had been suffering from intermittent abdominal pain, recurrent blood-tinged vomiting and poor oral intake. The gastric endoscopy revealed diffuse cobblestone appearance of the mucosa with easy touch bleeding throughout the stomach but no abnormalities in the esophagus, duodenum, and colon. Pathologic examination of the gastric biopsies from the antrum, body and cardia showed a subepithelial collagen deposition with entrapped dilated capillaries, moderate infiltrates of lympho-plasma cells and eosinophils of the lamina propria, and marked hypertrophy of the muscularis mucosa. The collagen deposition appeared as discontinuous bands with focally irregular extension into the deeper part of the antral mucosa. It measured up to 150 microm. Helicobacter pylori infection was not detected. The biopsies from the duodenum, esophagus and colon revealed no pathologic abnormalities. PMID:15716621

    Objective To evaluate the clinical manifestations, endoscopic features and the clinical pathological characteristics of H. heilmannii-associated gastritis, and to compare these variables with those of H. pylori-ussociated gastritis. Methods The clinical data, endoscopic findings and pathologic characteristics of 3107 patients, who underwent endoscopy from 2005 to 2007, were retrospectively analyzed. Results Twenty-five cases of H. heilmannii infection were identified, the infection rates of H. heilmannii and H. pylori were 0.80% (25/3107) and 4.12% (1060/3107) respectively. Three cases were mixed infections. Of 25 patients, 20 showed such gastroenterologic symptoms to a greater or less extent as abdominal distending pain,nausea and anorexia, and other 5 cases were asymptomatic. All 25 patients showed chronic gastritis by en-doscopy, including chronic superficial gastritis (7/25, 28% ), erosion ( 3/25, 12% ), chronic atrophic gastritis (4/25, 16%), bile reflux(1/25, 4%), ulcer (1/25, 4%), polyp (1/25, 4%) and duodenal bulbar inflammation (2/25, 8% ). In rapid urease test, 3 cases were hyper-positive, 3 cases positive, 7 ca-ses mild-positive and 12 cases negative. According to histological observation, H. heilmannii scattered or ac-cumulated within the gastric pits, glandular lumen or mucus. The organism was observed in parietal cells with cell damage in one case. Sporadic lymphatic and plasmic infiltration were found in all patients with H.heilmannii infection, infiltration of neutrophils (12/25), gland atrophy and intestinal metaplasia (4/25)and lymphoid follicles (6/25) were also observed. Compared with H. pylori-associated gastritis, H. heilman-nii-associated gastritis showed less inflammation, less helicobacter density, mononuclear cell infiltration and neutrophilic activity ( P < 0.05 ). Conclusion H. heilmanaii mainly induces chronic gastritis, which is less severe than H. pylori-associated gastritis.%目的 评估上消化道H.heilmannii感染的临床表现

    Jen-Pi Tsai

    Full Text Available BACKGROUND: Reduced turnover of extracellular matrix has a role in renal fibrosis. Matrix metalloproteinases (MMPs is associated with many glomerular diseases, but the histological association of MMPs and human renal fibrosis is unclear. METHODS: This is a retrospective study. Institutional Review Board approval was obtained for the review of patients' medical records, data analysis and pathological specimens staining with waiver of informed consents. Specimens of forty-six patients were examined by immunohistochemical stain of MMP-9 in nephrectomized kidneys, and the association of renal expression of MMP-9 and renal fibrosis was determined. MMP-9 expression in individual renal components and fibrosis was graded as high or low based on MMP-9 staining and fibrotic scores. RESULTS: Patients with high interstitial fibrosis scores (IFS and glomerular fibrosis scores (GFS had significantly higher serum creatinine, lower estimated glomerular filtration rate (eGFR, and were more likely to have chronic kidney disease (CKD and urothelial cell carcinoma. Univariate analysis showed that IFS and GFS were negatively associated with normal and atrophic tubular cytoplasmic MMP-9 expression and IFS was positively correlated with atrophic tubular nuclear MMP-9 expression. Multivariate stepwise regression indicated that MMP-9 expression in atrophic tubular nuclei (r = 0.4, p = 0.002 was an independent predictor of IFS, and that MMP-9 expression in normal tubular cytoplasm (r = -0.465, p<0.001 was an independent predictor of GFS. CONCLUSIONS: Interstitial fibrosis correlated with MMP-9 expression in the atrophic tubular nuclei. Our results indicate that renal fibrosis is associated with a decline of MMP-9 expression in the cytoplasm of normal tubular cells and increased expression of MMP-9 in the nuclei of tubular atrophic renal tubules.

  3. INTEGRATING CORPUS CONSULTATION IN LANGUAGE STUDIES

    2005-05-01

    Full Text Available Alongside developments in language research, the potential of corpora as a resource in language learning and teaching has been evident to researchers and teachers since the late 1960s. Despite publications which emphasise the benefits of corpus consultation for language learners (Bernardini, 2002; Kennedy & Miceli, 2001, there is little evidence to suggest that direct corpus consultation is coming to be seen as a complement or alternative to consultation of a dictionary, course book, or grammar by the majority of learners. There is thus a need for research to underpin the integration of corpora and concordancing in the language-learning environment.This study begins with an account of published research relating to course design and structure in the area of corpus consultation by language learners. The focus then narrows to the initial training of learners in corpus consultation, using as an example a course involving undergraduate students on several language degree programmes. The results of the students' consultation of the corpora are examined, including choice of search word(s, analytical skills, the problems encountered, and their evaluation of the activity. The results reveal how corpus consultation can complement traditional language-learning resources, while also raising questions concerning its integration in the language-learning environment.

    AIM: To assess the mechanisms of protective action by different mild irritants through maintenance of gastric mucosal integrity and modulation of mucosal nitric oxide (NO) in experimental gastritis rats.METHODS: Either 200 ml/L ethanol, 50 g/L NaCl or 0.3 mol/LHCl was pretreated to normal or 800 mL/L ethanol-induced acute gastritis Sprague-Dawley rats before a subsequent challenge with 500 mL/L ethanol. Both macroscopic lesion areas and histological damage scores were determined in the gastric mucosa of each group of animals. Besides,gastric mucosal activities of NO synthase isoforms and of superoxide dismutase, along with mucosal level of leukotriene (LT)C4 were measured.RESULTS: Macroscopic mucosal damages were protected by 200 mL/L ethanol and 50 g/L NaCl in gastritis rats.However, although 200 mL/L ethanol could protect the surface layers of mucosal cells in normal animals (protection attenuated by NG-nitro-L-arginine methyl ester), no cytoprotection against deeper histological damages was found in gastritis rats. Besides, inducible NO synthase activity was increased in the mucosa of gastritis animals and unaltered by mild irritants. Nevertheless, the elevation in mucosal LTC4 level following 500 mL/L ethanol administration and under gastritis condition was significantly reduced by pretreatment of all three mild irritants in both normal and gastritis animals.CONCLUSION: These findings suggest that the aggravated 500 mL/L ethanol-evoked mucosal damages under gastritis condition could be due to increased inducible NO and LTC4 production in the gastric mucosa. Only 200 mL/L ethanol is truly "cytoprotective" at the surface glandular level of nongastritis mucosa. Furthermore, the macroscopic protection of the three mild irritants involves reduction of LTC4 level in both normal and gastritis mucosa, implicating preservation of the vasculature.

    Lymphocytic gastritis and lymphocytic colitis are two rare disorders of unknown etiology, only diagnosable by histology. Simultaneous occurrence of lymphocytic colitis and lymphocytic gastritis has not been described up to now. A 69-year-old female patient was examined because of crampy abdominal pain and watery diarrhea. Laboratory tests did not reveal an etiology and in colonoscopy the colon and terminal ileum were normal. Histology disclosed lymphocytic colitis. Esophagogastroduodenoscopy showed erosive bulbitis. Biopsies of the stomach revealed lymphocytic gastritis. A second colonoscopy one year later showed the development of collagenous colitis. PMID:8367708

    We report a case of radiation gastritis in consequence of radiotherapy for recurrent ovarian cancer. A 61-year-old woman received irradiation of a metastatic lesion of the second lumbar vertebra. Six months later she complained of fatigue and presented with severe anemia, and her diagnosis was hemorrhagic radiation gastritis. She was treated endoscopically, but that failed to control the bleeding, making it necessary to resect surgically. The incidence of radiation gastritis is very low because the stomach is rarely within the treated field, but it is of importance to be aware that the stomach is by no means more radioresistant than other organs.

    2010-02-01

    Full Text Available In much of the literature on the exploitation of corpora for language learning, the learners are viewed as researchers, who formulate and test their own hypotheses about language use. Having identified difficulties encountered in corpus investigations by our intermediate-level students of Italian in a previous study, we have designed a semester-long apprenticeship in corpus use which does not demand of them the high level of language proficiency, attention to detail in observation, and logical rigour that we consider necessary for rewarding work in the learner-as-researcher role. Instead, we introduce a corpus initially as an aid to the imagination in writing, and then to achieving accuracy through specific grammatical problem solving. We see this as the groundwork for subsequent development of the students’ research skills with corpus data. This paper describes the approach we have adopted to the corpus apprenticeship and reports on an evaluation of its effectiveness through case studies of three students and their use of a corpus and bilingual dictionary as reference resources when writing. Drawing on insights from the case studies, we outline a working definition of corpus-consultation literacy for our learning context and identify some refinements to be made to our apprenticeship.

    The aim of this study was to identify the species and determine the prevalence of gastric Helicobacter in the saliva of dogs with gastritis. The study was carried out on 30 dogs of different breeds, genders and ages, which were diagnosed with gastritis. The nested-PCR method was used to detect Helicobacter spp. in saliva. Helicobacter bacteria were found in the saliva samples of 23 (76.6%) dogs. Helicobacter heilmannii was the most commonly detected species of gastric Helicobacter spp. in canine saliva, and was found in 22 (73.3%) cases. The results indicate that gastric Helicobacter spp. occurs relatively frequently in dogs with gastritis. Moreover, the saliva of dogs with gastritis may be a source of Helicobacter spp. infection for humans and other animals. However, further studies are needed to confirm this finding as the PCR method does not distinguish active from inactive infections. PMID:27096797

Helicobacter pylori (H. pylori infection is known to be the must common cause of chronic gastritis having some endoscopic and pathologic characteristies as determinated by the Sydney System for Gastritis Classification. The aim of our case report was to point out the relationship between an endoscopic finding of nodular antritis and the presence of H. pylori infection and active chronic gastritis. Case report. Our patient underwent upper gastrointestinal endoscopy for dyspeptic complaints and was diagnosed as having nodular antritis, but also underwent urease test and hystopathologic examination of antral mucosa, to determine the presence and density of H. pylori infection and the presence and severity of gastritis. After a course of anti H. pylori treatment, dyspepsia improved and new biopsy specimens obtained two months and six months afterwards revealed no pathological findings. Conclusion. The case report supported the association of H. pylori infection of lymphoid follicles with nodular gastric mucosis.

    AIM: Lymphocytic gastritis is commonly ass ociated with Helicobacter pylori infection. The presence of glandular atrophy and foveolar hyperplasia in lymphocytic gastritis suggests abnormalities in cell proliferation and differentiation,forming a potential link with the suspected association with gastric cancer. Our aim was to compare epithelial cell proliferation and morphology in H pylori associated lymphocytic gastritis and H pylori gastritis without features of lymphocytic gastritis,and to evaluate the effect of H pylori treatment.METHODS: We studied 14 lymphocytic gastritis patients with H pylori infection. For controls, we selected 14 matched dyspeptic patients participating in another treatment trial whose H pylori infection had successfully been eradicated.Both groups were treated with a triple therapy and followed up with biopsies for 6-18 months (patients) or 3 months (controls). Blinded evaluation for histopathological features was carried out. To determine the cell proliferation index,the sections were labeled with Ki-67 antibody.RESULTS: Before treatment, lymphocytic gastritis was characterized by foveolar hyperplasia (P=0.001) and glandular atrophy in the body (P=0.008), and increased proliferation in both the body (P=0.001) and antrum (P=0.002). Proliferation correlated with foveolar hyperplasia and inflammation activity. After eradication therapy, the number of intraepithelial lymphocytes decreased in the body (P=0.004)and antrum (P=0.065), remaining higher than in controls (P<0.001). Simultaneously, the proliferation index decreased in the body from 0.38 to 0.15 (P=0.043), and in the antrum from 0.34 to 0.20 (P=0.069), the antral index still being higher in lymphocytic gastritis than in controls (P=0.010).Foveolar hyperplasia and glandular atrophy in the body improved (P=0.021), reaching the non-LG level.CONCLUSION: In lymphocytic gastritis, excessive epithelial cell proliferation is predominantly present in the body, where it associates with

  19. Major motor atrophic patterns in the face and neck: CT evaluation

    International Nuclear Information System (INIS)

    Cranial nerve deficits from various pathologic processes of the head and neck may result in characteristic patterns of denervation muscular atrophy. Such atrophic patterns may be clues to the location and extent of the lesion, particularly when cranial nerves are involved early in the course of the disease process. Thirty-six patients with computed tomographic (CT) evidence of muscular atrophy secondary to pathologic conditions involving the motor division of cranial nerves were examined. Five characteristic denervation muscular atrophy patterns seen on CT scans were identified. Recognition of these atrophic patterns can prevent misinterpretation of their CT appearance and direct the CT examination to the course of the compromised cranial nerve from the brainstem to its peripheral innervation

    2012-07-01

    Full Text Available Abstract Background Manually annotated corpora are critical for the training and evaluation of automated methods to identify concepts in biomedical text. Results This paper presents the concept annotations of the Colorado Richly Annotated Full-Text (CRAFT Corpus, a collection of 97 full-length, open-access biomedical journal articles that have been annotated both semantically and syntactically to serve as a research resource for the biomedical natural-language-processing (NLP community. CRAFT identifies all mentions of nearly all concepts from nine prominent biomedical ontologies and terminologies: the Cell Type Ontology, the Chemical Entities of Biological Interest ontology, the NCBI Taxonomy, the Protein Ontology, the Sequence Ontology, the entries of the Entrez Gene database, and the three subontologies of the Gene Ontology. The first public release includes the annotations for 67 of the 97 articles, reserving two sets of 15 articles for future text-mining competitions (after which these too will be released. Concept annotations were created based on a single set of guidelines, which has enabled us to achieve consistently high interannotator agreement. Conclusions As the initial 67-article release contains more than 560,000 tokens (and the full set more than 790,000 tokens, our corpus is among the largest gold-standard annotated biomedical corpora. Unlike most others, the journal articles that comprise the corpus are drawn from diverse biomedical disciplines and are marked up in their entirety. Additionally, with a concept-annotation count of nearly 100,000 in the 67-article subset (and more than 140,000 in the full collection, the scale of conceptual markup is also among the largest of comparable corpora. The concept annotations of the CRAFT Corpus have the potential to significantly advance biomedical text mining by providing a high-quality gold standard for NLP systems. The corpus, annotation guidelines, and other associated resources are

    2015-01-01

    Corpus Christi Bay and Nueces Bay comprise the middle estuarine portion of Texas’ Coastal Bend region (Figure 1; Burgan and Engle, 2006). Aransas Bay is part of the upper estuarine portion of the region. These bays make up part of the Coastal Bend Bays and Estuaries Program, one of the many estuarine areas in the U.S. Environmental Protection Agency’s National Estuary Program (Holt, 1998). The Coastal Bend region is sub-humid and sub-tropical. Summers are long, hot, and humid, and winters are short and mild. The landscape around the estuaries is dominated by row crops, pastures, and brushy rangeland (Handley and others, 2007). The Nueces River, along with other smaller rivers and creeks, provides freshwater inflow—along with essential nutrients and sediment— into Nueces Bay, which feeds into Corpus Christi Bay (Holt, 1998). Freshwater inflow into the Aransas Bay comes from Mission River, Aransas River, and Copano Creek. The region is relatively dry otherwise and prone to droughts. Corpus Christi receives an average of 76.2 cm (30 in) of rain annually; evaporation usually exceeds 177.8 cm (70 in) (Holt, 1998; Handley and others, 2007). The San Antonio-Nueces Coastal Basin drains into Aransas Bay. The Nueces River basin covers 43,253 km2 (16,700 miles2 ), from northwest of San Antonio, flowing southeast to where it drains into Nueces and Corpus Christi Bays (Holt, 1998). The Nueces-Rio Grande basin covers approximately 18,648 1 U.S. Geological Survey National Wetlands Research Center, 700 Cajundome Blvd., Lafayette, LA 70506 2 Harte Research Institute for Gulf of Mexico Studies, Texas A&M University - Corpus Christi, 6300 Ocean Drive, Unit 5869, Corpus Christi, Texas 78412 2 km2 (7,200 miles2 ) and flows partially into Corpus Christi Bay (as well as the upper Laguna Madre). The inflow from Nueces River has declined by approximately 20 percent over the past several decades, partly due to construction of lakes and reservoirs, particularly Lake Corpus Christi

  16. Disappearance of Helicobacter without Antibiotics in 12 Patients with Gastritis

    Directory of Open Access Journals (Sweden)

    Hugh James Freeman

    1997-01-01

    Full Text Available Detection of Helicobacter pylori in endoscopic gastric biopsies has been associated with a variety of diseases, including ulcers and gastritis. Although the natural history of H pylori in the gastric mucosa is unknown, antibiotic regimens have been used for eradication. Gastric biopsies from 6050 endoscopic procedures done by a single gastroenterologist from 1981 to 1994 were evaluated. Of these, 2860 from April 1, 1991 to September 30, 1994 had silver-stained biopsies to facilitate H pylori detection, and at least two upper endoscopic procedures were done with gastric biopsies in 188 patients. Twelve of the 188 patients with an initially positive H pylori gastric biopsy became H pylori-negative without antibiotic treatment for H pylori or other infection; 10 received omeprazole and two received no drug treatment. In two of the 12 patients recurrent H pylori in the gastric mucosa was also documented. These findings indicate that H pylori may disappear and reappear in the gastric mucosa with no specific antibiotic eradication regimen, although omeprazole may eradicate H pylori in vivo in some patients. The natural history of H pylori in gastric biopsies is poorly understood. Improved understanding, especially regarding the pathogenesis of upper gastrointestinal ulcerative and inflammatory disease processes, is essential before recommendations for specific antibiotic eradication regimens can be made.

  17. Bayesian Stratified Sampling to Assess Corpus Utility

    1998-01-01

    This paper describes a method for asking statistical questions about a large text corpus. We exemplify the method by addressing the question, "What percentage of Federal Register documents are real documents, of possible interest to a text researcher or analyst?" We estimate an answer to this question by evaluating 200 documents selected from a corpus of 45,820 Federal Register documents. Stratified sampling is used to reduce the sampling uncertainty of the estimate from over 3100 documents to fewer than 1000. The stratification is based on observed characteristics of real documents, while the sampling procedure incorporates a Bayesian version of Neyman allocation. A possible application of the method is to establish baseline statistics used to estimate recall rates for information retrieval systems.

  18. Corpus-Based Word Sense Disambiguation

    CERN Document Server

    Fujii, A

    1998-01-01

    Resolution of lexical ambiguity, commonly termed ``word sense disambiguation'', is expected to improve the analytical accuracy for tasks which are sensitive to lexical semantics. Such tasks include machine translation, information retrieval, parsing, natural language understanding and lexicography. Reflecting the growth in utilization of machine readable texts, word sense disambiguation techniques have been explored variously in the context of corpus-based approaches. Within one corpus-based framework, that is the similarity-based method, systems use a database, in which example sentences are manually annotated with correct word senses. Given an input, systems search the database for the most similar example to the input. The lexical ambiguity of a word contained in the input is resolved by selecting the sense annotation of the retrieved example. In this research, we apply this method of resolution of verbal polysemy, in which the similarity between two examples is computed as the weighted average of the simi...

    2015-11-01

    Full Text Available This article has two main purposes. The first is to provide a short panorama of existing trends within computer-assisted stylistics. The second is to analyse a prize winning novel by English writer Julian Barnes, by resorting to the tenets and working tools of one of the newest branch of Stylistics, the so-called Corpus stylistics. To this end, the article starts by looking at various attempts at defining what style is and their implications to the definition of the discipline known as Stylistics. Then the paper presents recent work within the field of Corpus stylistics, as it describes the uses of computational tools as part of the stylistician tool kit. Finally, the paper provides a variety of ways with which a literary work may be approached digitally with a view to showing how computational tools can aid the stylistician in acts of interpretation.

    The semantic analysis of documents is a domain of intense research at present. The works in this domain can take several directions and touch several levels of granularity. In the present work we are exactly interested in the thematic analysis of the textual documents. In our approach, we suggest studying the variation of the theme relevance within a text to identify the major theme and all the minor themes evoked in the text. This allows us at the second level of analysis to identify the relations of thematic associations in a textual corpus. Through the identification and the analysis of these association relations we suggest generating thematic paths allowing users, within the frame work of information search system, to explore the corpus according to their themes of interest and to discover new knowledge by navigating in the thematic association relations.

    2008-12-01

    Full Text Available Information technologies have now matured to the point of enabling researchers to create a repository of language resources, especially for those languages facing the crisis of endangerment. The development of an online platform of corpora, made possible by recent advances in data storage, character-encoding and web technology, has profound consequences for the accessibility, quantity, quality and interoperability of linguistic field data. This is of particular significance for Formosan languages in Taiwan, many of which are on the verge of extinction. As a response to the recognition of this burgeoning problem, the key objectives of the establishment of the NTU Corpus of Formosan Languages aim to document and thus preserve valuable linguistic data, as well as relevant ethnological and cultural information. This paper will introduce some of the theoretical bases behind this initiative, as well as the procedures, transcription conventions, database normalization, in-house system and three special features in the creation of this corpus.

    Honesto Herrera Soler

    2008-04-01

    Full Text Available In linguistics a corpus typically involves a finite body of texts which are considered to be representative of a particular variety of language at a specific time (McEnery & Wilson, 2001. Those are the assumptions we have had in mind in this metaphor corpus based on business press headlines. Our body of texts is a finite number of headlines drawn from the specific field of the business sections of three newspapers: Financial Times, El País and El Mundo, published over a period running from January to July 2003. Compiling a small corpus of non-literal instantiations as different authors have done (Cortés de los Ríos, 2001; Kövecses, 2002; Charteris-Black, 2003; Koller, 2004; Deignan, 2005; and others will enable us first to identify whether the contextual meaning of a word or a multiword unit of headline contrasts with its basic meaning and whether the contextual meaning can be understood by comparison with that basic meaning, and then to categorize, both in the Spanish and in the British press, the different linguistic realizations of a headline in terms of their syntactic structure, metaphor foci and source domains.

  5. Tumors of the corpus callosum: imaging diagnosis

    International Nuclear Information System (INIS)

    Objective: To study the imaging features of tumors in the corpus callosum. Methods: Different imaging data of 25 tumors in the corpus callosum were retrospectively analyzed. Results: Of the 25 cases, 2 cases were anaplastic astrocytomas, 7 cases were glioblastomas, 10 cases were malignant lymphomas, 1 case for each in the following tumors: low grade astrocytoma, oligodendroglioma, anaplastic oligodendroglioma, oligoastrocytoma, lipoma, and metastatic tumor. The lesion's size varied from 7 cm to 0.5 cm. These lesions were usually iso-or hypointense on T1-weighted images and hyper-in- tense on T1-weighted images with focal necrosis, and showed ring-like or 'butterfly sign' enhancement after administration of contract medium. Lipoma showed hypodensity on CT with attenuation value of -85 HU. Glioblastomas and malignant lymphomas usually infiltrated into cerebral ventricles and brain parenchyma. Conclusions: Tumors of the corpus callosum have characteristic imaging features. MRI exam before surgery is helpful for the surgical excision. (authors)

  6. Named Entity Recognition Using Web Document Corpus

    Directory of Open Access Journals (Sweden)

    Wahiba Ben Abdessalem Karaa

    2011-02-01

    Full Text Available This paper introduces a named entity recognition approach in textual corpus. This Named Entity (NE can be a named: location, person, organization, date, time, etc., characterized by instances. A NE isfound in texts accompanied by contexts: words that are left or right of the NE. The work mainly aims at identifying contexts inducing the NE’s nature. As such, The occurrence of the word "President" in atext, means that this word or context may be followed by the name of a president as President "Obama". Likewise, a word preceded by the string "footballer" induces that this is the name of afootballer. NE recognition may be viewed as a classification method, where every word is assigned to a NE class, regarding the context. The aim of this study is then to identify and classify the contexts that are most relevant to recognize aNE, those which are frequently found with the NE. A learning approach using training corpus: web documents, constructed from learning examples is then suggested. Frequency representations andmodified tf-idf representations are used to calculate the context weights associated to context frequency, learning example frequency, and document frequency in the corpus.

  7. Immunoglobulin gene repertoire diversification and selection in the stomach – from gastritis to gastric lymphomas

    Directory of Open Access Journals (Sweden)

    Miri eMichaeli

    2014-06-01

    Full Text Available Chronic gastritis is characterized by gastric mucosal inflammation due to autoimmune responses or infection, frequently with Helicobacter pylori. Gastritis with H. pylori background can cause gastric mucosa-associated lymphoid tissue lymphoma (MALT-L, which sometimes further transforms into diffuse large B cell lymphoma (DLBCL. However, gastric DLBCL can also be initiated de novo. The mechanisms underlying transformation into DLBCL are not completely understood. We analyzed immunoglobulin repertoires and clonal trees to investigate whether and how immunoglobulin gene repertoires, clonal diversification and selection in gastritis, gastric MALT-L and DLBCL differ from each other and from normal responses. The two gastritis types (positive or negative for H. pylori had similarly diverse repertoires. MALT-L dominant clones presented higher diversification and longer mutational histories compared with all other conditions. DLBCL dominant clones displayed lower clonal diversification, suggesting the transforming events are triggered by similar responses in different patients. These results are surprising, as we expected to find similarities between the dominant clones of gastritis and MALT-L and between those of MALT-L and DLBCL.

    2014-01-01

    Full Text Available Background: While laser resurfacing remains the most effective treatment option for atrophic acne scars, the high incidence of post-treatment adverse effects limits its use. Fractional laser photothermolysis attempts to overcome these limitations of laser resurfacing by creating microscopic zones of injury to the dermis with skip areas in between. Aim: The aim of the present study is to assess the efficacy and safety of fractional CO 2 laser resurfacing in atrophic facial acne scars. Materials and Methods: Sixty patients with moderate to severe atrophic facial acne scars were treated with 3-4 sessions of fractional CO 2 laser resurfacing at 6-week intervals. The therapeutic response to treatment was assessed at each follow up visit and then finally 6 months after the last laser session using a quartile grading scale. Response to treatment was labelled as ′excellent′ if there was >50% improvement in scar appearance and texture of skin on the grading scale while 25-50% response and <25% improvement were labelled as ′good′ and ′poor′ response, respectively. The overall satisfaction of the patients and any adverse reactions to the treatment were also noted. Results: Most of the patients showed a combination of different morphological types of acne scars. At the time of final assessment 6 months after the last laser session, an excellent response was observed in 26 patients (43.3% while 15 (25% and 19 patients (31.7% demonstrated a good and poor response respectively. Rolling and superficial boxcar scars responded the best while pitted scars responded the least to fractional laser monotherapy. The commonest reported adverse effect was transient erythema and crusting lasting for an average of 3-4 and 4-6 days, respectively while three patients developed post-inflammatory pigmentation lasting for 8-12 weeks. Conclusions: Fractional laser resurfacing as monotherapy is effective in treating acne scars especially rolling and superficial boxcar

    Full Text Available STUDY BACKGROUND Post acne scars are always a challenge to treat, especially the ones which are deep seated. There are many treatment options like laser resurfacing, dermabrasion, microdermabrasion and non-ablative laser resurfacing but with considerable morbidity and interference with the daily activities of the patient in the post-treatment period. Microneedling or dermaroller therapy is one of the new treatment options in the management of acne scars with satisfactory improvement and no significant side effect. The aim of the present study is to perform an objective evaluation the efficacy of microneedling in the treatment of atrophic acne scars. MATERIALS AND METHODS Thirty patients of skin type III-V having atrophic facial acne scars presenting to our dermatology OPD. were received multiple sittings of microneedling (dermaroller treatment with an interval of 6 weeks between each session. Goodman & Baron’s acne scar grading system was used for assessment of their scars and was evaluated clinically by serial photography at the start as well as at two months after the conclusion of the treatment. Patients on anticoagulant therapy, of keloidal tendency, with bleeding disorders, vitiligo patients, pregnant and lactating mothers and patients with active acne lesions were excluded from the study. The duration of this study was for ten months-from January 2014 to October 2014. RESULTS Any change in the grading of scars after the end of treatment and follow-up period was noted down. The efficacy and improvement of dermaroller treatment was assessed by Goodman and Baron’s Global Acne Scarring System. Out of 30 patients, 26(80.64% patients achieved a reduction in the severity of their scarring by one or two grades. Quantitative assessment showed that 13.3% of patients had minimal, 16.6% had good and 70% showed very good improvement. Adverse effects were limited to transient pain, erythema and edema.

    Abstract: The Ndebele language corpus described here is that compiled by the ALLEX Project (now ALRI at the University of Zimbabwe. It is intended to reflect as much as possible the Ndebele language as spoken in Zimbabwe. The Ndebele language corpus was built in order to provide much-needed material for the study of the Ndebele language with a special focus on dictionarymaking and research. Like most corpora, the Ndebele language corpus may in future be used for other purposes not thought of at the time of its inception. It has been designed to meet generally acceptable standards so that it can be adaptable to various possible uses by various researchers. The article wants to outline the building process of the Ndebele language corpus with special emphasis on the challenges that faced compilers, and possible solutions. It is assumed that some of these challenges might not be peculiar to Ndebele alone but could also affect related African languages in a more or less similar situation. The main focus of the discussion will be the composition of the Ndebele language corpus, i.e. the type of texts that constitute the corpus. The corpus is composed of published texts, unpublished texts and oral material gathered from Ndebele-speaking districts of Zimbabwe. It will be argued that the use of the corpus and its reliability for research depends among other factors on its contents. It will also be shown that the contents of a corpus depend on a number of factors, some of which include sociolinguistic, political and economic considerations. These considerations have implications on both the content and quality of published and oral texts that constitute the Ndebele language corpus.

    Radiation-induced gastritis is an infrequent cause of gastrointestinal bleeding.It is a serious complication arising from radiation therapy,and the standard treatment method has not been established.The initial injury is characteristically acute inflammation of gastric mucosa.We presented a 46-year-old male patient with hemorrhagic gastritis induced by external radiotherapy for metastatic retroperitoneal lymph node of hepatocellular carcinoma.The endoscopic examination showed diffuse edematous hyperemicmucosa with telangiectasias in the whole muscosa of the stomach and duodenal bulb.Mlultiple hemorrhagic patches with active oozing were found over the antrum.Anti-secretary therapy was initiated for hemostasis,but melena still occurred off and on.Finally,he was successfully treated by prednisolone therapy.We therefore strongly argue in favor of perdnisolone therapy to effectively treat patients with radiation-induced hemorrhagic gastritis.

  16. Divergent Approaches to Corpus Processing: The Need for Standardisation

    Directory of Open Access Journals (Sweden)

    2011-10-01

    Full Text Available Abstract: This article discusses some problems encountered in the processing of the Shona corpus. Most of the problems deal with the handling of adoptives, punctuation and individuals' idiolects. It also discusses the problem ensuing from an attempt to standardise the formats used in the handling of the corpus. The way a corpus is processed is critical in determining its quality. This article aims to show how the different lin-guistic backgrounds of the processors affect the appreciation of some vital aspects of the corpus. One of the acclaimed advantages of a corpus is that it allows research to be done on natural language. An ideal corpus should be a body of texts combined in a principled way to become a reliable language bank from which researchers retrieve data for various research purposes. With a good corpus, data can be provided giving an authoritative body of linguistic evidence which can support generalisations and against which hypotheses can be tested. As this proves the invaluable status of a corpus, the article assesses the processing of the Shona corpus and discusses how some aspects of the processing may impact negatively on its quality.

    shows support for Cheshire et al. (2005). This difference in the direction of change is explained by socio-psychological processes linking linguistic forms, the local Tyneside area and speaker identity. More specifically, it is argued that speakers imbue local vernacular variants with social meaning......Cheshire et al. (2005) argue that different levels of language do not necessarily follow the same patterns of change over time. In an attempt to test this prediction, this article reports on a comparison between two quantitative corpus studies of Tyneside English which are partly based on the same...... at a time when this area is undergoing vast changes....

    2011-01-01

    Short Message Service (SMS) messages are largely sent directly from one person to another from their mobile phones. They represent a means of personal communication that is an important communicative artifact in our current digital era. As most existing studies have used private access to SMS corpora, comparative studies using the same raw SMS data has not been possible up to now. We describe our efforts to collect a public SMS corpus to address this problem. We use a battery of methodologies to collect the corpus, paying particular attention to privacy issues to address contributors’ concerns. Our live project collects new SMS message submissions, checks their quality and adds the valid messages, releasing the resultant corpus as XML and as SQL dumps, along with corpus statistics, every month. We opportunistically collect as much metadata about the messages and their sender as possible, so as to enable different types of analyses. To date, we have collected about 60,000 messages, focusing on English and...

    1992-08-01

    The content of ascorbin acid and thiamin was assessed in the food ration of 36 patients with chronic gastritis and ulcer disease. By the end treatment including dietotherapy these vitamins showed a deficit. Correction of this deficit of the above mentioned vitamins with a polyvitamine drug "Supradin" allowed to improve significantly the biochemical indices and availability of ascorbic acid and thiamin in patients with chronic gastritis and ulcer disease. The treatment produced a favourable effect on the clinical course of the disease, reduction of the pain syndrome and earlier recovery. PMID:1475934

  3. Progressive atrophic rhinitis in a medium-scale pig farm in Kiambu, Kenya : case report

    Directory of Open Access Journals (Sweden)

    J.K. Wabacha

    2000-07-01

    Full Text Available Forty-two pigs in a herd of 117 displayed various clinical signs of progressive atrophic rhinitis. The main signs included sneezing, coughing, lachrymation, serous to muco-purulent nasal discharge, and nasal bleeding in 1 pig. Three pigs had lateral deviation of the snout, while 4 had brachygnathia superior with obvious deformation of the face. Four acutely affected weaner pigs appeared weak, while the 7 chronically-affected pigs appeared smaller than their apparently unaffected penmates of the same age. Treatment of the acutely affected pigs with long-acting oxytetracycline at 20 mg/kg body weight intra-muscularly, repeated once after 7 days, reduced the severity but did not clear the sneezing from all the pigs. Fifteen pigs were slaughtered 2 months after the clinical diagnosis was made. The carcasses of the chronically affected pigs were about 15 % lighter than those of the apparently normal pigs of the same age and from the same pen, which translated to a loss of 921.00 Kenya shillings per pig (US$13.7. Diagnosis of progressive atrophic rhinitis was confirmed by sectioning the snouts of randomly selected slaughtered pigs with obvious deformation of the snout. Sections were madeat the level of the 1st/2nd upper premolar tooth. Varying degrees of turbinate atrophy, from mild to complete, were noted. Histopathology of the turbinates revealed metaplasia of nasal epithelium and fibrosis in the lamina propria.

  4. A two-short-implant-supported molar restoration in atrophic posterior maxilla: A finite element analysis

    Science.gov (United States)

    2016-01-01

    PURPOSE The aim of this study was to investigate the stress distribution of 2-short implants (2SIs) installed in a severely atrophic maxillary molar site. MATERIALS AND METHODS Three different diameters of internal connection implants were modeled: narrow platform (NP), regular platform (RP), and wide platform (WP). The maxillary first molars were restored with one implant or two short implants. Three 2SI models (NP-oblique, NP-vertical, and NP-horizontal) and four single implant models (RP and WP in a centered or cantilevered position) were used. Axial and oblique loadings were applied on the occlusal surface of the crown. The von Mises stress values were measured at the bone-implant, peri-implant bone, and implant/abutment complex. RESULTS The highest stress distribution at the bone-implant interface and the peri-implant bone was noticed in the RP group, and the lowest stress distribution was observed in the 2SI groups. Cantilevered position showed unfavorable stress distribution with axial loading. 2SI types did not affect the stress distribution in oblique loading. The number and installation positions of the implant, rather than the bone level, influenced the stress distribution of 2SIs. The implant/abutment complex of WP presented the highest stress concentration while that of 2SIs showed the lowest stress concentration. CONCLUSION 2SIs may be useful for achieving stable stress distribution on the surrounding bone and implant-abutment complex in the atrophic posterior maxilla.

  6. Named Entity Recognition Using Web Document Corpus

    CERN Document Server

    Karaa, Wahiba Ben Abdessalem

    2011-01-01

    This paper introduces a named entity recognition approach in textual corpus. This Named Entity (NE) can be a named: location, person, organization, date, time, etc., characterized by instances. A NE is found in texts accompanied by contexts: words that are left or right of the NE. The work mainly aims at identifying contexts inducing the NE's nature. As such, The occurrence of the word "President" in a text, means that this word or context may be followed by the name of a president as President "Obama". Likewise, a word preceded by the string "footballer" induces that this is the name of a footballer. NE recognition may be viewed as a classification method, where every word is assigned to a NE class, regarding the context. The aim of this study is then to identify and classify the contexts that are most relevant to recognize a NE, those which are frequently found with the NE. A learning approach using training corpus: web documents, constructed from learning examples is then suggested. Frequency representatio...

  10. Magnetic resonance imaging in agenesis of corpus callosum

    International Nuclear Information System (INIS)

    The recent use of computed tomography (CT) scan is providing an easy diagnoses of agenesis of corpus callosum which had been difficult to diagnose only by clinical signs and symptoms. Since, more neuropsychological studies on agenesis of corpus callosum are being done, clinical details of agenesis of corpus callosum are being clarified. We examined magnetic resonance imaging (MRI) on 3 patients who were suspected to have agenesis of corpus callosum by CT scan. And we studied the usefulness of MRI in agenesis of corpus callosum. By sagittal MRI, we could easily make a diagnosis on one case (Case 3) of hypoplasia of corpus callosum which could not been diagnosed by CT scan. On all of the cases, MRI showed the high intensity area of anterior commissure which had not been found by CT scan. Anomaly of cingurate gyrus was shown on all of the patients. MRI can show some important points in detail which CT scan can not reveal. The sagittal view especially is the most helpful for diagnosis of agenesis of corpus callosum. And we proposed that neuropsychological study on agenesis of corpus callosum should have MRI data. (J.P.N.)

  15. MR measurement of normal corpus callosum in children

    International Nuclear Information System (INIS)

    To measure the mean size of the various portions of the corpus callosum in normal Korean children, using MR imaging. Our subjects were 166 children (male : female=100 : 66) aged under 15 whose findings on MR imaging and neurologic examination were normal. Using midsagittal T1-weighted imaging, we measured the length of the brain and corpus callosum, the height of the latter, and the thickness of its genu body, transitional zone and splenium. The measurements were statistically analysed according to age and sex. Brain length and the size of the various portions of the corpus callosum tended to increase relatively rapidly during the first three years of life, but the rate of growth tended to decrease according to age. The mean lenght of the brain and corpus callosum and the mean thickness of the splenium of the corpus callosum did not differ according to sex. The mean thickness of the genu, body and transitional zone of the corpus callosum was greater in males than in females. The ratio of the length of the corpus callosum to the anteroposterior diameter of the brain was significantly greater in females than in males (alpha=0.05). Using MR imaging, we measured the mean sizes of the various portions of the corpus callosum in normal children;these values may provide a useful basis for determing changes occurring in its structure

    Full Text Available Curcuma aromatica is an herbal medicine and traditionally used for the treatment of various diseases in Asia. We investigated the effects of C. aromatica water extract (CAW in the stomach of rats with ethanol-induced gastritis. Gastritis was induced in rats by intragastric administration of 5 mL/kg body weight of absolute ethanol. The CAW groups were given 250 or 500 mg of extract/kg 2 h before administration of ethanol, respectively. To determine the antioxidant effects of CAW, we determined the level of lipid peroxidation, the level of reduced glutathione (GSH, the activities of catalase, degree of inflammation, and mucus production in the stomach. CAW reduced ethanol-induced inflammation and loss of epithelial cells and increased the mucus production in the stomach. CAW reduced the increase in lipid peroxidation associated with ethanol-induced gastritis (250 and 500 mg/kg, p<0.01, resp. and increased mucosal GSH content (500 mg/kg, p<0.01 and the activity of catalase (250 and 500 mg/kg, p<0.01, resp.. CAW increased the production of prostaglandin E2. These findings suggest that CAW protects against ethanol-induced gastric mucosa injury by increasing antioxidant status. We suggest that CAW could be developed for the treatment of gastritis induced by alcohol.

    We examined the effects of visual deprivation at birth on the development of the corpus callosum in a large group of congenitally blind individuals. We acquired high-resolution T1-weighted MRI scans in 28 congenitally blind and 28 normal sighted subjects matched for age and gender. There was no...... overall group effect of visual deprivation on the total surface area of the corpus callosum. However, subdividing the corpus callosum into five subdivisions revealed significant regional changes in its three most posterior parts. Compared to the sighted controls, congenitally blind individuals showed a 12......% reduction in the splenium, and a 20% increase in the isthmus and the posterior part of the body. A shape analysis further revealed that the bending angle of the corpus callosum was more convex in congenitally blind compared to the sighted control subjects.

    AIM: To compare the reliability of gastritis staging systems in ranking gastritis-associated cancer risk in a large series of consecutive patients.METHODS: Gastric mucosal atrophy is the precancerous condition in which intestinal-type gastric cancer (GC) most frequently develops. The operative link for gastritis assessment (OLGA) staging system ranks the GC risk according to both the topography and the severity of gastric atrophy (as assessed histologically on the basis of the Sydney protocol for gastric mucosal biopsy). Both cross-sectional and long-term follow-up trials have consistently associated OLGA stages Ⅲ-Ⅳ with a higher risk of GC. A recently-proposed modification of the OLGA staging system (OLGIM) basically incorporates the OLGA frame, but replaces the atrophy score with an assessment of intestinal metaplasia (IM) alone. A series of 4552 consecutive biopsy sets (2007-2009) was retrieved and reassessed according to both the OLGA and the OLGIM staging systems. A set of at least 5 biopsy samples was available for all the cases considered.RESULTS: In 4460 of 4552 cases (98.0%), both the high-risk stages (Ⅲ + Ⅳ) and the low-risk stages (0 +Ⅰ + Ⅱ) were assessed applying the OLGA and OLGIM criteria. Among the 243 OLGA high-risk stages, 14 (5.8%) were down-staged to a low risk using OLGIM. The 67 (1.5%) incidentally-found neoplastic lesions (intraepithelial or invasive) were consistently associated with high-risk stages, as assessed by both OLGA and OLGIM (P < 0.001 for both). Two of 34 intestinal-type GCs coexisting with a high-risk OLGA stage (stage Ⅲ) were associated with a low-risk OLGIM stage (stage Ⅱ).CONCLUSION: Gastritis staging systems (both OLGA and OLGIM) convey prognostically important information on the gastritis-associated cancer risk. Because of its clinical impact, the stage of gastritis should be included as a conclusive message in the gastritis histology report. Since it focuses on IM alone, OLGIM staging is less sensitive than

    2014-04-01

    We report 3 cases of primary renal cell tumor simulating atrophic kidney with distinct gross, morphologic, immunohistochemical, and molecular genetic features. The tumors were retrieved out of more than 17 000 renal tumors from the Plzen Tumor Registry. Tissues for light microscopy had been fixed, embedded, and stained with hematoxylin and eosin using routine procedures. The tumors were further analyzed using immunohistochemistry, array comparative genomic hybridization, and human androgen receptor. Analyses of VHL gene and loss of heterozygosity (LOH) 3p were also performed. The patients were 2 women and 1 man, with ages ranging from 29 to 35 years (mean, 31.3 years). Grossly, the neoplasms were encapsulated and round with largest diameter of 3.5 cm (mean, 3.2 cm). Follow-up available for all patients ranged from 2 to 14 years (mean, 8 years). No aggressive behavior was noted. Histologically, akin to atrophic (postpyelonephritic) kidney parenchyma, the tumors were composed of follicles of varying sizes that were filled by eosinophilic secretion. Rare areas contained collapsed follicles. Each follicle was endowed with a small capillary. The stroma was loose, inconspicuous, and focally fibrotic. Two types of calcifications were noted: typical psammoma bodies and amorphous dark-blue stained calcified deposits. Immunohistochemically, tumors were strongly positive for cytokeratins (OSCAR), CD10, and vimentin, with weak immunopositivity for CAM5.2 and AE1-AE3.

    Helicobacter pylori infection triggers chronic inflammation of the gastric mucosa that may progress to gastric cancer. The hypoxia-inducible factors (HIFs) are the central mediators of cellular adaptation to low oxygen levels (hypoxia), but they have emerged recently as major transcriptional regulators of immunity and inflammation. No studies have investigated whether H. pylori affects HIF signaling in immune cells and a potential role for HIF in H. pylori-mediated gastritis. HIF-1 and HIF-2 expression was examined in human H. pylori-positive gastritis biopsies. Subsequent experiments were performed in naive and polarized bone marrow-derived macrophages from wild-type (WT) and myeloid HIF-1α-null mice (HIF-1(Δmyel)). WT and HIF-1(Δmyel) mice were inoculated with H. pylori by oral gavage and sacrificed 6 mo postinfection. HIF-1 was specifically expressed in macrophages of human H. pylori-positive gastritis biopsies. Macrophage HIF-1 strongly contributed to the induction of proinflammatory genes (IL-6, IL-1β) and inducible NO synthase in response to H. pylori. HIF-2 expression and markers of M2 macrophage differentiation were decreased in response to H. pylori. HIF-1(Δmyel) mice inoculated with H. pylori for 6 mo presented with a similar bacterial colonization than WT mice but, surprisingly, a global increase of inflammation, leading to a worsening of the gastritis, measured by an increased epithelial cell proliferation. In conclusion, myeloid HIF-1 is protective in H. pylori-mediated gastritis, pointing to the complex counterbalancing roles of innate immune and inflammatory phenotypes in driving this pathology.

    AIM: To assess the possibility of non-invasive screening of atrophic chronic gastritis for preventing further development of gastric cancer.METHODS: One hundred and seventy-eight consecutive Helicobacter pylori ( H pylori)-positive dyspeptic patients after detection of serum levels of pepsinogen-1 (PG-1) and gastrin-17 (G-17) by enzyme immunoassay were proposed for endoscopy and histology. The serologic and morphologic results were compared with estimating the sensitivity,specificity and prognostic values of the tests.RESULTS: There was statistically significant reverse dependence between the grade of stomach mucosal antral or corpus atrophy and the proper decreasing of serum G17or PG1 levels. The serologic method was quite sensitive in the diagnosis of non-atrophic and severe antral and corpus gastritis. Also, it was characterized by the high positive and negative prognostic values.CONCLUSION: Detection of serum G-17 and PG1 levels can be offered as the screening tool for atrophic gastritis. The positive serologic results require further chromoendoscopy with mucosal biopsy, for revealing probable progressing of atrophic process with development of intestinal metaplasia,dysplasia or gastric cancer.

  6. Corpus-Based Word Sense Disambiguation

    Resolution of lexical ambiguity, commonly termed ``word sense disambiguation'', is expected to improve the analytical accuracy for tasks which are sensitive to lexical semantics. Such tasks include machine translation, information retrieval, parsing, natural language understanding and lexicography. Reflecting the growth in utilization of machine readable texts, word sense disambiguation techniques have been explored variously in the context of corpus-based approaches. Within one corpus-based framework, that is the similarity-based method, systems use a database, in which example sentences are manually annotated with correct word senses. Given an input, systems search the database for the most similar example to the input. The lexical ambiguity of a word contained in the input is resolved by selecting the sense annotation of the retrieved example. In this research, we apply this method of resolution of verbal polysemy, in which the similarity between two examples is computed as the weighted average of the similarity between complements governed by a target polysemous verb. We explore similarity-based verb sense disambiguation focusing on the following three methods. First, we propose a weighting schema for each verb complement in the similarity computation. Second, in similarity-based techniques, the overhead for manual supervision and searching the large-sized database can be prohibitive. To resolve this problem, we propose a method to select a small number of effective examples, for system usage. Finally, the efficiency of our system is highly dependent on the similarity computation used. To maximize efficiency, we propose a method which integrates the advantages of previous methods for similarity computation.

    Abstract: Language corpora are now indispensable to dictionary compilation. They help broaden the role of the dictionary from standardizing the vocabulary to recording a language. The trilingual corpus generated by the Hong Kong Polytechnic University gives a record of business languages used in Hong Kong. It differs from other corpora in that (1 it includes English, Chinese and Japanese; (2 it shows local characteristics; and (3 it focuses on a specific area (financial services, including banking, accounting, auditing, insurance and investment. The paper discusses various issues of setting up a tricorpus, and how to make full use of the data to generate a trilingual lexicon.

    Full Text Available Ocular defects may cause several ocular and orbital disorders, which require surgical intervention. These defects are psychologically disturbing for the patients, and therefore, they require immediate management and rehabilitation by a team of specialist. Ocular prosthesis may be either readymade (stock or custom made. Fabrication of a custom ocular prosthesis allows for a range of variations during construction. The iris can also be custom made by ocular painting or by digital photography. The optimum cosmetic and functional results of a custom-made prosthesis enhance the patient′s rehabilitation to a normal life style. This paper elaborates the technique for fabrication of a custom-made ocular prosthesis for an atrophic eye socket utilizing digital photography.

    Objectives To explore the therapeutic potential of combining bone marrow-derived mesenchymal stem cells (BM-MSCs) and hydroxyapatite (HA) granules to treat nonunion of the long bone. Methods Ten patients with an atrophic nonunion of a long bone fracture were selectively divided into two groups. Five subjects in the treatment group were treated with the combination of 15 million autologous BM-MSCs, 5g/cm3 (HA) granules and internal fixation. Control subjects were treated with iliac crest autograft, 5g/cm3 HA granules and internal fixation. The outcomes measured were post-operative pain (visual analogue scale), level of functionality (LEFS and DASH), and radiograph assessment. Results Post-operative pain evaluation showed no significant differences between the two groups. The treatment group demonstrated faster initial radiographic and functional improvements. Statistically significant differences in functional scores were present during the first (p = 0.002), second (p = 0.005) and third (p = 0.01) month. Both groups achieved similar outcomes by the end of one-year follow-up. No immunologic or neoplastic side effects were reported. Conclusions All cases of nonunion of a long bone presented in this study were successfully treated using autologous BM-MSCs. The combination of autologous BM-MSCs and HA granules is a safe method for treating nonunion. Patients treated with BM-MSCs had faster initial radiographic and functional improvements. By the end of 12 months, both groups had similar outcomes. Cite this article: H.D. Ismail, P. Phedy, E. Kholinne, Y. P. Djaja, Y. Kusnadi, M. Merlina, N. D. Yulisa.

    Full Text Available Long bone and in particular tibia fractures frequently fail to heal. A disturbed revascularisation is supposed to be a major cause for impaired bone healing or the development of non-unions. We aim to establish an animal model, which reliably mimics the clinical situation. Human microvascular endothelial cells (HMEC-1 and primary human osteoblast like cells (POBs were cultured with different angiogenesis-inhibitors (Fumagillin, SU5416, Artesunate and 3,5,4’-Trimethoxystilbene released out of poly(D,L-Lactide (PDLLA coated k-wires and cell activity was determined. Discs containing PDLLA or PDLLA + Fumagillin/Artesunate were placed at the chorionallantoic membrane of hen eggs and the effect on vessel formation and egg vitality was observed. Tibia osteotomy was performed in rats and stabilised with K-wires coated with PDLLA + Fumagillin or with PDLLA only (control group. The healing was compared at different time points to the PDLLA control. Fumagillin and Artesunate inhibited the activity of HMEC-1 with minor effect on POBs. Artesunate caused embryonic death, whereas Fumagillin had no effects on egg vitality, but reduced the blood vessels. In the animal study all rats showed an impaired healing with reduced biomechanical stability. The Fumagillin treated tibiae had a significantly decreased callus size at day 42 and 84, less blood vessels in the early callus, a reduced histological callus size at day 10, 28 and 84, as well as an altered callus composition. This study presents a less vascularised, atrophic, tibia non-union and can be used in further investigations to analyse the pathology of atrophic non-union and to test new interventions.

    Full Text Available Background: Atrophic vaginitis is a disease, which affects up to 50% of postmenopausal women. This study compared the effectiveness and user-friendliness of Vagifem (an estradiol vaginal tablet and vaginal estrogen cream in the treatment of atrophic vaginitis. Materials and Methods: One hundred and sixty postmenopausal women with symptoms of atrophic vaginitis were randomly divided into two groups of treatment with Vagifem or with vaginal estrogen cream for 12 weeks. Patients used the medication daily for the first 2 weeks of the study, and twice weekly. Severity of vaginal atrophy and four main symptoms of atrophic vaginitis including dysuria, dyspareunia, vaginal itching, and dryness were evaluated and compared before and after treatment. In addition, patients were asked regarding user-friendliness and hygienic issues of medications. Results: Both vaginal estrogen cream and Vagifem significantly improved symptoms of atrophic vaginitis but in terms of effectiveness for the treatment symptoms of atrophic vaginitis, there was no significant difference between the two medications. Vagifem compared to estrogen cream resulted in significantly lower rate of hygienic problems (0% versus 23%, P < 0.001, and was reported by the patients as a significantly easier method of treatment (90% versus 55%, P < 0.0001. Conclusion: This investigation showed that Vagifem is an appropriate medication for the treatment of atrophic vaginitis, which is as effective as vaginal estrogen creams and is more user-friendly.

  13. Corpus Linguistics and the Design of a Response Message

    Most research related to SETI, the Search for Extra-Terrestrial Intelligence, is focussed on techniques for detection of possible incoming signals from extra-terrestrial intelligent sources (e.g. Turnbull et al. 1999), and algorithms for analysis of these signals to identify intelligent language-like characteristics (e.g. Elliott and Atwell 1999, 2000). However, another issue for research and debate is the nature of our response, should a signal arrive and be detected. The design of potentially the most significant communicative act in history should not be decided solely by astrophysicists; the Corpus Linguistics research community has a contribution to make to what is essentially a Corpus design and implementation project. (Vakoch 1998) advocated that the message constructed to transmit to extraterrestrials should include a broad, representative collection of perspectives rather than a single viewpoint or genre; this should strike a chord with Corpus Linguists for whom a central principle is that a corpus must be "balanced" to be representative (Meyer 2001). One idea favoured by SETI researchers is to transmit an encyclopaedia summarising human knowledge, such as the Encyclopaedia Britannica, to give ET communicators an overview and "training set" key to analysis of subsequent messages. Furthermore, this should be sent in several versions in parallel: the text; page-images, to include illustrations left out of the text-file and perhaps some sort of abstract linguistic representation of the text, using a functional or logic language (Ollongren 1999, Freudenthal 1960). The idea of "enriching" the message corpus with annotations at several levels should also strike a chord with Corpus Linguists who have long known that Natural language exhibits highly complex multi-layering sequencing, structural and functional patterns, as difficult to model as sequences and structures found in more traditional physical and biological sciences. Some corpora have been annotated with

    Epididymal sperm preservation can be used to avoid the total loss of genetic material in threatened species. Spermatozoa from the corpus, as from the cauda, are motile and can undergo capacitation. Thus, they can potentially be preserved for assisted reproductive technologies. However, cryopreservation of spermatozoa has a direct detrimental effect on sperm quality. The aim of this study was to compare the chromatin stability and the survival rate of spermatozoa from the corpus and cauda epididymis after cryopreservation. Epididymal spermatozoa were collected and cryopreserved from the corpus and cauda of 12 domestic cats. Sperm motility, progressive motility, membrane integrity, acrosome integrity, and DNA integrity were evaluated before and after freezing thawing. The average total number of spermatozoa collected from the corpus was lower (10.2 × 10(6) ± 7.4) than that from the cauda epididymis (24.9 × 10(6) ± 14.4; P = 0.005). The percentage of spermatozoa with intact DNA did not differ significantly whether it was collected from the corpus or cauda regions and did not decrease after freezing thawing in either region. However, motility of spermatozoa from both regions was affected by the freezing thawing process with a significant decline in motility after thaw compared with fresh spermatozoa. A significant difference in the percentage of motile sperm between the corpus and cauda was observed after the freezing thawing process (P < 0.001). Although sperm motility was lower in postthaw spermatozoa from the corpus epididymidis than from the cauda, the rate of the reduction did not differ between regions. This study indicates that the cryopreservation process does not have a negative effect on chromatin stability of feline epididymal spermatozoa. Spermatozoa from the corpus region have a similar freezability as spermatozoa from the cauda region. Therefore, preservation of spermatozoa from the corpus and the cauda epididymidis might be of value in preserving

    Full Text Available Psychiatric symptoms may occasionally be related to anatomic alterations of brain structures. Particularly, corpus callosum lesions seem to play a role in the change of patients’ behavior. We present a case of a sudden psychotic attack presumably due to a hemorrhagic cavernous angioma of the corpus callosum, which was surgically removed with complete resolution of symptoms. Although a developmental defect like agenesis or lipoma is present in the majority of these cases, a growing lesion of the corpus callosum can rarely be the primary cause. Since it is potentially possible to cure these patients, clinicians should be aware of this association.

    Full Text Available Abstract Background The aim of this study is evaluating the correlation of postprandial fullness with chronic gastritis or rapid inflow of gastric content into duodenum, based on double-contrast barium X-ray imaging. Methods 253 healthy subjects who underwent upper gastrointestinal barium X-ray examination were analyzed. Chronic gastritis was judged from mucosal atrophy and hypertrophic thickened folds on barium X-ray images. For the gastric excretion, the tips of barium flow on the single-contrast frontal barium X-ray images of the stomach were classified into four categories; V type (all the barium remained in the stomach, V-H type (some barium had flowed into the duodenum but the tip of barium remained in the proximal half of the duodenal bulb, H-V type (some barium had flowed into the duodenum and the tip of barium was in the distal half of duodenal the bulb, but no barium was observed in the descending part of the duodenum, and H type (some barium had flowed into the descending part of the duodenum. The chi-square test and Cochran-Mantel-Haenzel test were used for evaluation. Results Chronic gastritis was observed in 72 subjects, among which 21 subjects (29.2% presented with postprandial fullness. For the remaining 181 subjects without chronic gastritis, 53 subjects (29.3% complained of postprandial fullness. There is no significant correlation between chronic gastritis and postprandial fullness (p = 0.973. For the rapid flow of gastric content into duodenum, all the 253 subjects comprised 136 subjects with V type (in the stomach, 40 subjects with V-H type (in the proximal half of the duodenal bulb, 21 subjects with H-V type (in the distal half of the duodenal bulb, and 56 subjects with H type (in the descending part of the duodenum.

    Abstract: This article presents various approaches used in corpus-based computational lexico-graphy. A claim is made that in order for computational lexicography to be efficient, precise and comprehensive, it should utilize the method where the corpus text is first analysed, and the results of this analysis is then processed further to meet the needs of a dictionary. This method has several advantages, including high precision and recall, as well as the possibility to automate the process much further than with more traditional computational methods. The frequency list obtained by using the lemma (the equivalent of the headword as basis helps in selecting the words to be in-cluded in the dictionary. The approach is demonstrated through various phases by applying SALAMA (the Swahili Language Manager to the process. Manual work will be needed in the phase when examples of use are selected from the corpus, and possibly modified. However, the list of examples of use, arranged alphabetically according to the corresponding headword, can also be produced automatically. Thus the alphabetical list of headwords with examples of use is the mate-rial on which the lexicographer works manually. The article deals with problems encountered in compiling traditional printed dictionaries, and it excludes electronic dictionaries and thesauri.

    Hippocrates (Island of Kos, 460 B.C.-Larissa, 370 B.C.) is the founder of the most famous Medical School of the classical antiquity. In acknowledgement of his pioneering contribution to the new scientific field of Paediatric Virology, this article provides a systematic analysis of the Hippocratic Corpus, with particular focus on viral infections predominating in neonates and children. A mumps epidemic, affecting the island of Thasos in the 5th century B.C., is described in detail. ‘Herpes’, a medical term derived from the ancient Greek word ‘ἕρπειν’, meaning ‘to creep’ or ‘crawl’, is used to describe the spreading of cutaneous lesions in both childhood and adulthood. Cases of children with exanthema ‘resembling mosquito bites’ are presented in reference to varicella or smallpox infection. A variety of upper and lower respiratory tract viral infections are described with impressive accuracy, including rhinitis, pharyngitis, tonsillitis, laryngitis, bronchiolitis and bronchitis. The ‘cough of Perinthos’ epidemic, an influenza-like outbreak in the 5th century B.C., is also recorded and several cases complicated with pneumonia or fatal outcomes are discussed. Hippocrates, moreover, describes conjunctivitis, otitis, lymphadenitis, meningoencephalitis, febrile convulsions, gastroenteritis, hepatitis, poliomyelitis and skin warts, along with proposed treatment directions. Almost 2,400 years later, Hippocrates' systematic approach and methodical innovations can inspire paediatric trainees and future Paediatric Virology subspecialists. PMID:27446241

    Full Text Available A 47-year-old, single, Chinese woman presented with pain on the 1st day of menses for more than 30 years. Her dysmenorrhea worsened over years and underwent a total abdominal hysterectomy and bilateral salpingooophorectomy. The myometrium showed trabeculated appearance, and there were adhesions between ovaries and fallopian tubes. A pale solid brownish mass measuring 1.5 cm and times; 1 cm and times; 0.6 cm with fibrous whitish cut surfaces was present on the lateral wall of the uterus in the lower uterine segment. Histologically, adenomyosis and left ovarian endometriosis were confirmed. The lateral uterine wall nodule showed a tubular structure lined by ciliated pseudostratified columnar epithelium. Smooth muscle bundles were found around the entire tubular structure. Lobules of salivary type glands containing both serous and mucous cells are present. The pathological diagnosis of heterotopic respiratory mucosa (HRM was made. To our knowledge, this is the first reported case of HRM of the uterine corpus.

    A 76-year-old female patient was admitted to the Level I Emergency Department of University of Szeged with severe abdominal pain and vomiting. The clinical assessment with laboratory tests and radiological investigations confirmed severe sepsis associated with intravascular hemolysis and multiorgan failure and acute pancreatitis. On the abdominal CT, besides of other abnormalities, the presence of gas bubbles in the stomach, small intestines and liver were seen. The gastric alterations pointed to emphysematous gastritis. Despite of the medical treatment, the patient's condition quickly deteriorated and eight hours after admission the patient died. The autopsy evaluation revealed systemic infection of abdominal origin caused by gas-producing Gram-positive bacteria, and the post-mortem microbiological cultures confirmed the presence of Cloctridium perfringens in many abdominal organs. Emphysematous gastritis seemed to be the primary infectious focus. PMID:27036998

    To evaluate, using magnetic resonance (MR) imaging, the clinal significance of the corpus callosum by measuring the size of various portions of the corpus callosum in children with cerebral palsy, and in paired controls. Fifty-two children (30 boys and 22 girls aged between six and 96 (median, 19) months) in whom cerebral palsy was clinically diagnosed underwent MR imaging. There were 23 term patients and 29 preterm, and the control group was selected by age and sex matching. Clinal subtypes of cerebral palsy were classified as hemiplegia (n=14), spastic diplegia (n=22), or spastic quadriplegia (n=16), and according to the severity of motor palsy, the condition was also classified as mild (n=26), moderate (n=13), or severe (n=13). In addition to the length and height of the corpus callosum, the thickness of its genu, body, transitional zone and splenium, as seen on midsagittal T1-weighted MR images, were also measured. Differences in the measured values of the two groups were statistically analysed and differences in the size of the corpus callosum according to the clinical severity and subtypes of cerebral palsy, and gestational age, were also assessed. Except for height, the measured values of the corpus callosum in patients with cerebral palsy were significantly less than those of the control group (p less than 0.05). Its size decreased according to the severity of motor palsy. Compared with term patients, the corpus callosum in preterm patients was considerably smaller (p less than 0.05). There was statistically significant correlation between the severity of motor palsy and the size of the corpus callosum. Quantitative evaluation of the corpus callosum might be a good indicator of neurologic prognosis, and a sensitive marker for assessing the extent of brain injury.

    Objective To examine the relationship between Helicobacter pylori-related gastritis and the development of lymphoid tissue hyperplasia in the antral mucosa and to pursue its evolution after eradication of H.pylori in the aged. Methods Gastric antral mucosa biopsy specimens for microscopic study were obtained from 101 chronic gastritis patients over 60 years old with H.pylori-positive in the period from 2000 to 2001, and meanwhile those from 124 H.pylori-positive chronic gastritis patients under the age of 60 served as controls. Four to six weeks after a course of anti-H.pylori therapy, biopsy specimens were again obtained. Lym-phoid follicles and aggregates were counted and other pathologic features were scored according to the updated Sydney System for classification of chronic gastritis. Results The prevalence and density of lymphoid follicles and aggregates were significantly lower in the aged as compared with those in the control group, being 36. 6%(37/101) and 0. 41 vs. 72. 5%(90/124) and 0. 81, respectively(P<0.0001). The prevalence and density of lymphoid follicles and aggregates correlated strongly with the activity and severity of gastric antral mucosal inflammation in both groups. Eradication of H.pylori resulted in a decrease in the prevalence and density of lymphoid follicles and aggregates in both groups, especially in the aged group. Conclusion The prevalence and density of lymphoid follicles and aggregates in gastric antral mucosal biopsies correlated closely with H.phlori infection in the aged, therefore, anti-H.pylori treatment would be of importance to the aged patients infected with H.pylori.

    Full Text Available PURPOSE: To describe a technique for en bloc harvesting of the corpus cavernosum, cavernous artery and urethra from transplant organ donors and contraction-relaxation experiments with corpus cavernosum smooth muscle. MATERIALS AND METHODS: The corpus cavernosum was dissected to the point of attachment with the crus penis. A 3 cm segment (corpus cavernosum and urethra was isolated and placed in ice-cold sterile transportation buffer. Under magnification, the cavernous artery was dissected. Thus, 2 cm fragments of cavernous artery and corpus cavernosum were obtained. Strips measuring 3 x 3 x 8 mm3 were then mounted vertically in an isolated organ bath device. Contractions were measured isometrically with a Narco-Biosystems force displacement transducer (model F-60, Narco-Biosystems, Houston, TX, USA and recorded on a 4-channel Narco-Biosystems desk model polygraph. RESULTS: Phenylephrine (1µM was used to induce tonic contractions in the corpus cavernosum (3 - 5 g tension and cavernous artery (0.5 - 1g tension until reaching a plateau. After precontraction, smooth muscle relaxants were used to produce relaxation-response curves (10-12M to 10-4 M. Sodium nitroprusside was used as a relaxation control. CONCLUSION: The harvesting technique and the smooth muscle contraction-relaxation model described in this study were shown to be useful instruments in the search for new drugs for the treatment of human erectile dysfunction.

    The purpose of the present study was to investigate Chinese EFL (English as a Foreign Language) teachers ’attitudes to-ward corpus use in collocation instruction. Fourteen Chinese EFL teachers from seven different colleges or universities answered a questionnaire asking their perceptions about corpus use in collocation instruction. The statistical analysis revealed that significant difference (t=2.449, df.=9, p=.037<0.1) was found between males and females in their perception of the learnability of the search-ing technique in collocation corpus. Besides, the result also revealed that significant differences were found between novice and experienced teachers’perception of helpfulness of corpus in writing native-like sentences (t=5.75, df=11, p<0.1), identifying col-location errors in English (t=5.75, df=11, p<0.1), usefulness of corpus in searching for English collocations (t=2.93, df=12, p<0.1), and advocacy of corpus to colleagues(t=5.75, df=11, p<0.1).

    The Pirahã language has been at the center of recent debates in linguistics, in large part because it is claimed not to exhibit recursion, a purported universal of human language. Here, we present an analysis of a novel corpus of natural Pirahã speech that was originally collected by Dan Everett and Steve Sheldon. We make the corpus freely available for further research. In the corpus, Pirahã sentences have been shallowly parsed and given morpheme-aligned English translations. We use the corpus to investigate the formal complexity of Pirahã syntax by searching for evidence of syntactic embedding. In particular, we search for sentences which could be analyzed as containing center-embedding, sentential complements, adverbials, complementizers, embedded possessors, conjunction or disjunction. We do not find unambiguous evidence for recursive embedding of sentences or noun phrases in the corpus. We find that the corpus is plausibly consistent with an analysis of Pirahã as a regular language, although this is not the only plausible analysis.

    Full Text Available Aim: We want to evaluate a new bone block material in the inlay technique, for the vertical bone augmentation of a posterior atrophic mandible, in order to perfom aesthetic and prosthetic rehabilitation and enable implant insertion. Materials & Methods: Inlay technique and the subsequent successful implant rehabilitation in the atrophic right posterior mandible in a 42-year-old woman, was completed using a cancellous equine bone block as grafting material. Results: Three months after surgical procedure both clinical and histological aspects show complete integration of the biomaterial with the surrounding bone and three dental implants were placed. Computed tomography and conventional radiography showed a 5mm mean vertical bone gain. Conclusion: Cancellous equine bone grafts may be an effective alternative to autogenous bone and/or inorganic bovine bone for reconstruction of the posterior mandible using inlay technique.

  12. Helicobacter pylori detection in chronic gastritis: a comparison of staining methods

    International Nuclear Information System (INIS)

    Background: Helicobacter pylori is an important cause of chronic gastritis, gastric ulceration and gastric malignancies as gastric carcinoma and MALT lymphoma. Its definitive diagnosis is based on histopathology. Routine H and E stain is not very effective in its detection, immune-stains and fluorescent stains are costly. Need for simple cheap and sensitive stain has always been a topic of hot debate and extensive research. Method: paraffin embedded blocks of all adult patients diagnosed as chronic gastritis/gastric ulceration with no accompanying gastric pathology as hypertrophic gastropathys, and neoplasias were taken into study. Three sections of 4 micron were cut and stained with routine H and E, Giemsa, and Cresyl fast violet. Results: Total number of patients was 50. Out of these 37 (74%) were males and 13 (26%) were females. Mean age of the patients was 50.4 years. Thirty-four percent (34%) were positive in normal H and E stain, 68% were positive in Giemsa and 76% were positive in Cresyl fast violet. Conclusion: Cresyl fast violet is a good stain for diagnosis of H. pylori gastritis. (author)

We detected and compared the PPTs of people with and without gastric ulcer or gastritis on the related acupoints, abdomen area, and back area with von Frey detector and observed the similarities and differences under their respective physiological and pathological states. The results showed that (1 the PPTs of patients with gastric ulcer on related acupoints decreased significantly compared with the control group; (2 there was no significant difference in PPT between the chosen points of the measured meridian and the adjacent nonacupoints; (3 there was an apparent distribution of tender points on the relevant abdomen and back regions of patients with gastric ulcer or gastritis, but none was found on the control group; (4 the pain-sensitive points of gastric ulcer and gastritis patients were BURONG (ST19, LIANGMEN (ST21, and HUAROUMEN (ST24 of the stomach meridian on the abdominal region and PISHU (BL20, WEISHU (BL21, and WEICANG (BL50 on the back, among others The results suggest that the practical significance of acupoints may lie in its role as a relatively sensitive functional area. In a pathological state, the reflex points on the skin which are related to certain visceral organs become sensitive and functionally intensify.

    We studied the preventive effect of cimetidine at the microscopic level on chronic erosive gastritis induced experimentally by 6-months of administration of drinking water containing 5 mmol/l of the sodium salt of taurocholic acid (TCA) in rats. The chronic erosive gastritis was characterized by mucosal erosions, reduction of mucosal thickness and reduction in the number of parietal cells per unit area, infiltration of inflammatory cells which were mainly lymphocytes and plasmocytes, and proliferation of collagenous fibers in the gastric mucosa. A standard meal including cimetidine 0.4 and 0.8%, which was administered ad libitum with TCA, reduced the total length of erosions, normalized the mucosal thickness and the number of parietal cells, and reduced inflammatory cell infiltration in the gastric mucosa. However, cimetidine did not show any effect on the proliferation of collagenous fibers in the interstitial space of the mucosa. The doses administered were 400 mg/kg/day and 800 mg/kg/day for 6 months. Cimetidine, thus, had a preventive effect on experimental chronic erosive gastritis in rats. PMID:2024066

    AIM: To assess expression of matrix metalloproteinases 2 (MMP2) and MMP9 in gastric cancer, superficial gastritis and normal mucosa, and to measure metalloproteinase activity. METHODS: MMP2 and MMP9 mRNA expression was determined by quantitative real-time polymerase chain reaction. Normalization was carried out using three different factors. Proteins were analyzed by quantitative gelatin zymography (qGZ). RESULTS: 18S ribosomal RNA (18SRNA) was very highly expressed, while hypoxanthine ribosyltransferase-1 (HPRT-1) was moderately expressed. MMP2 was highly expressed, while MMP9 was not detected or lowly expressed in normal tissues, moderately or highly expressed in gastritis and highly expressed in cancer. Relative expression of 18SRNA and HPRT-1 showed no significant differences. Significant differences in MMP2 and MMP9 were found between cancer and normal tissue, but not between gastritis and normal tissue. Absolute quantification of MMP9 echoed this pattern, but differential expression of MMP2 proved conflictive. Analysis by qGZ indicated significant differences between cancer and normal tissue in MMP-2, total MMP-9, 250 and 110 kDa bands. CONCLUSION: MMP9 expression is enhanced in gastric cancer compared to normal mucosa; interpretation of differential expression of MMP2 is difficult to establish. PMID:20333791

    Full Text Available The decrease in the prevalence of Helicobacter pylori (Hp infection in children in the world gave rise to a new pathological finding termed as Hp-negative gastritis. Unfortunately, the term “Hp-negative gastritis” has not been identified as a pathological process and has the status of a “second cousin”; in most publications it was never mentioned as a subject to be dealt with, but was “left over” data that was never the topic of the manuscripts’ discussions. Only recently has the topic captured the attention of the pathologists who described this phenomenon in adults, yet the pathological and/or clinical spectrum or significance of this phenomenon has not been adequately investigated. In the current manuscript we describe Hp-negative gastritis in children, summarize its clinical prevalence and touch upon the possible etiology, pathology, and/or therapeutic implication. Overall, this review has concluded that Hp-negative gastritis is a pathological phenomenon in children that needs further investigation, and to date, as the title suggests, is a new clinical enigma that needs to be considered.

    The aim of this study was to determine the drainage routes of the corpus cvernosum penis and the corpus spongiosum penis in the cat using contrast cavernosography. Five male cats, 1.5-2.5 years old, weighing between 4.5 and 5.5 kg were investigated. The cats were anesthetized and the root and the proximal part of the penis were exposed by an incision on the perineum reaching the scrotum. Each cat was radiographed in lateral and dorsal recumbency before and during injection of contrast medium into the erectile bodies. The corpus spongiosum penis was injected at the bulb of the penis and the corpus cavernosum penis at the root. Injection of contrast media into the cavernous bodies showed that both the external and internal iliac veins drain the erectile bodies into the caudal vena cava. Drainage from the corpus spongiosum penis was from the bulb for the proximal part and from the glans for the distal part. The corpus cavernosum penis was drained only proximally, from the crura. There was a network of veins above the pelvic symphysis and the drainage of erectile bodies where through various routes into the internal and external iliac veins.

  4. The FSHD atrophic myotube phenotype is caused by DUX4 expression.

    Directory of Open Access Journals (Sweden)

    Céline Vanderplanck

    Full Text Available BACKGROUND: Facioscapulohumeral muscular dystrophy (FSHD is linked to deletions in 4q35 within the D4Z4 repeat array in which we identified the double homeobox 4 (DUX4 gene. We found stable DUX4 mRNAs only derived from the most distal D4Z4 unit and unexpectedly extended to the flanking pLAM region that provided an intron and a polyadenylation signal. DUX4 encodes a transcription factor expressed in FSHD but not control primary myoblasts or muscle biopsies. The DUX4 protein initiates a large transcription deregulation cascade leading to muscle atrophy and oxidative stress, which are FSHD key features. METHODOLOGY/PRINCIPAL FINDINGS: We now show that transfection of myoblasts with a DUX4 expression vector leads to atrophic myotube formation associated with the induction of E3 ubiquitin ligases (MuRF1 and Atrogin1/MAFbx typical of muscle atrophy. DUX4 induces expression of downstream targets deregulated in FSHD such as mu-crystallin and TP53. We developed specific siRNAs and antisense oligonucleotides (AOs targeting the DUX4 mRNA. Addition of these antisense agents to primary FSHD myoblast cultures suppressed DUX4 protein expression and affected expression of the above-mentioned markers. CONCLUSIONS/SIGNIFICANCE: These results constitute a proof of concept for the development of therapeutic approaches for FSHD targeting DUX4 expression.

    Atrophic vaginitis (AV) is common in postmenopausal women, but its causes are not well understood. The symptoms, which include vaginal itching, burning, dryness, irritation, and dyspareunia, can usually be alleviated by low doses of estrogen given orally or locally. Regrettably, the composition of vaginal bacterial communities in women with AV have not been fully characterized and little is known as to how these communities change over time in response to hormonal therapy. In the present intervention study we determined the response of vaginal bacterial communities in postmenopausal women with AV to low-dose estrogen therapy. The changes in community composition in response to hormonal therapy were rapid and typified by significant increases in the relative abundance of Lactobacillus spp. that were mirrored by a decreased relative abundance of Gardnerella. These changes were paralleled by a significant four-fold increase in serum estradiol levels and decreased vaginal pH, as well as nearly a two-fold increase in the Vaginal Maturation Index (VMI). The results suggest that after menopause a vaginal microbiota dominated by species of Lactobacillus may have a beneficial role in the maintenance of health and these findings that could lead to new strategies to protect postmenopausal women from AV.

    Whether or not the atrophic skeletal muscle induces insulin resistance and its mechanisms are not resolved now. The antigravity soleus muscle showed a progressive atrophy in 1-week, 2-week, and 4-week tail-suspended rats. Hyperinsulinemic-euglycemic clamp showed that the steady-state glucose infusion rate was lower in 4-week tail-suspended rats than that in the control rats. The glucose uptake rates under insulin- or contraction-stimulation were significantly decreased in 4-week unloaded soleus muscle. The key protein expressions of IRS-1, PI3K, and Akt on the insulin-dependent pathway and of AMPK, ERK, and p38 on the insulin-independent pathway were unchanged in unloaded soleus muscle. The unchanged phosphorylation of Akt and p38 suggested that the activity of two signal pathways was not altered in unloaded soleus muscle. The AS160 and GLUT4 expression on the common downstream pathway also was not changed in unloaded soleus muscle. But the GLUT4 translocation to sarcolemma was inhibited during insulin stimulation in unloaded soleus muscle. The above results suggest that hindlimb unloading in tail-suspended rat induces atrophy in antigravity soleus muscle. The impaired GLUT4 translocation to sarcolemma under insulin stimulation may mediate insulin resistance in unloaded soleus muscle and further affect the insulin sensitivity of whole body in tail-suspended rats.

    This paper presents the treatment results and experiences gained from a retrospective study of patients treated with the IMZ osseo-integrated implant system and mandibular overdentures. Patients experiencing problems wearing conventional dentures were assessed by the implant team and 65 cases were treated with 154 endosseous implants placed in the edentulous mandible. Two to four implants were placed in each case and in addition some patients have had augmentation of the mandible with hydroxyapatite. The definitive mandibular prostheses were supported by both implants and the residual ridges. A variety of retention systems were utilised, which included different types of bar and clip, stud attachments, and magnets. The patients have been followed up regularly and evaluated after periods of between one and six years. Six implants have failed over this time resulting in a success rate of over 96%. Most patients expressed a high degree of satisfaction with their new overdentures. There was, however, a considerable burden of maintenance care required for the patient group examined. The findings demonstrate that implant retained overdentures offer a highly effective means of oral rehabilitation for the atrophic mandible, restoring both oral function and facial form.

    Full Text Available Purpose. This systematic review was aimed at assessing the feasibility by means of survival rate, histologic analysis, and causes of failure of allogeneic block grafts for augmenting the atrophic maxilla. Material and Methods. A literature search was conducted by one reviewer in several databases. Articles were included in this systematic review if they were human clinical trials in which outcomes of allogeneic bone block grafts were studied by means of survival rate. In addition other factors were extracted in order to assess their influence upon graft failure. Results. Fifteen articles fulfilled the inclusion criteria and subsequently were analyzed in this systematic review. A total of 361 block grafts could be followed 4 to 9 months after the surgery, of which 9 (2.4% failed within 1 month to 2 months after the surgery. Additionally, a weighed mean 4.79 mm (95% CI: 4.51–5.08 horizontal bone gain was computed from 119 grafted sites in 5 studies. Regarding implant cumulative survival rate, the weighed mean was 96.9% (95% CI: 92.8–98.7%, computed from 228 implants over a mean follow-up period of 23.9 months. Histologic analysis showed that allogeneic block grafts behave differently in the early stages of healing when compared to autogenous block grafts. Conclusion. Atrophied maxillary reconstruction with allogeneic bone block grafts represents a reliable option as shown by low block graft failure rate, minimal resorption, and high implant survival rate.

    Collagenous gastritis is a rare disease in the general population and collagenous colitis has seldom been reported in children. We report a girl with both diseases and review the literature on this association afetr a systematic search of Pubmed, Medline and Embase databases.. The girl, diagnosed of collagenous colitis at the age of 2 years, started with abdominal pain and anaemia at the age of 9 years and was diagnosed of collagenous gastritis in the gastric biopsies. After review of the literature, we found 66 reported cases (33 children, 33 adults, 68% females), 56 patients with collagenous gastritis and 16 children with collagenous colitis. Both disorders coexisted in 20 patients. The main presenting symptoms are abdominal pain and anaemia in patients with collagenous gastritis and diarrhoea and weight loss in patients with both disorders. Hypoalbuminemia was found in 9 patients with both diseases and protein losing enteropathy was demonstrated in 3 cases. Deposits of collagen in the duodenum were observed in 13 of 19 patients with both diseases. Seventeen of 66 patients had associated autoimmune disorders, particularly in patients with both diseases (35%). These conditions have a chronic course but gastric or colonic malignancies have not been communicated to date. In conclusion, collagenous gastritis and collagenous colitis mainly affects women and can occur at any age. Their association is exceptional. These disorders, although rare, should be considered in patients with anaemia and epigastric pain, watery diarrhoea or protein losing enteropathy. PMID:22103057

    Full Text Available Aim: To evaluate the efficacy of the treatment method of autogenous iliac wing or radius bone graft and fixation with screw applied to cases of scaphoid non-union. Material and Method: A retrospective evaluation was made of 89 cases between 2000 and 2014. Postoperative measurements were taken of both wrists%u2019 movement with a goniometer and muscle strength was assessed with a dynamometer. Fractures were evaluated radiologically according to the Herbert-Fisher System and the functional results according to the Herbert-Fisher Classification System and the Mayo Clinic Modified Wrist Scoring System. The data were input to the SPSS system and evaluated with the Shapiro-Wilk test. Results: Non-union were on the right side in 47 and the left side in 42 cases. The fracture was seen to be in the waist in 60 cases (67.5%, in the proximal third in 27 cases (30.3% and in the distal third in two cases (2.2%. The mean follow-up period was 16.4 months (range, 5-72 months. Definitive findings of union were observed in 71 cases. The mean time to union was 14.9 weeks (range, 8-40 weeks. Discussion: The grafting procedure applied is an invasive technique but if it is considered that there are negative effects of open surgery on the feeding of the scaphoid bone, then in the treatment of scaphoid non-union which is atrophic non-union, ultimately autogenous bone grafting and screw fixation is a safe and successful method and because of the pain created by an iliac wing graft, radius distal bone graft can be considered more appropriate.

Because standard diagnostic techniques might provide falsely negative results, we evaluated the sonication method for detection of bacteria on implants of patients with fracture nonunions. A total of 49 patients with a nonunion (group NU and, for comparison, 45 patients who had undergone routine removal of osteosynthetic material (group OM, were included in the study. Five different diagnostic methods (culture of tissue samples, culture of intraoperative swabs, histopathology of tissue samples, culture of sonication fluid, and 16S ribosomal DNA polymerase chain reaction of sonication fluid were compared and related to clinical data. Among the diagnostic tests, culture of sonication fluid demonstrated by far the highest detection rate of bacteria (57% in group NU, and rather unexpectedly 40% in group OM. Culture of sonication samples also revealed a broad spectrum of bacteria, in particular Propionibacterium spp. In conclusion, our results indicate that more bacteria can be detected on implants of patients with atrophic nonunions of long-bone fractures by means of the sonication procedure, which provides a valuable additional diagnostic tool to decide on a surgical procedure (eg, two-step procedure and to further specify antimicrobial therapy.

  15. Diffusion tensor analysis of corpus callosum in progressive supranuclear palsy

    International Nuclear Information System (INIS)

    Progressive supranuclear palsy (PSP) is a neurodegenerative disease featuring parkinsonism, supranuclear ophthalmoplegia, dysphagia, and frontal lobe dysfunction. The corpus callosum which consists of many commissure fibers probably reflects cerebral cortical function. Several previous reports showed atrophy or diffusion abnormalities of anterior corpus callosum in PSP patients, but partitioning method used in these studies was based on data obtained in nonhuman primates. In this study, we performed a diffusion tensor analysis using a new partitioning method for the human corpus callosum. Seven consecutive patients with PSP were compared with 29 age-matched patients with Parkinson's Disease (PD) and 19 age-matched healthy control subjects. All subjects underwent diffusion tensor magnetic resonance imaging, and the corpus callosum was partitioned into five areas on the mid-sagittal plane according to a recently established topography of human corpus callosum (CC1-prefrontal area, CC2-premotor and supplementary motor area, CC3-motor area, CC4-sensory area, CC5-parietal, temporal, and occipital area). Fractional anisotropy (FA) and apparent diffusion coefficient (ADC) were measured in each area and differences between groups were analyzed. In the PSP group, FA values were significantly decreased in CC1 and CC2, and ADC values were significantly increased in CC1 and CC2. Receiver operating characteristic analysis showed excellent reliability of FA and ADC analyses of CC1 for differentiating PSP from PD. The anterior corpus callosum corresponding to the prefrontal, premotor, and supplementary motor cortices is affected in PSP patients. This analysis can be an additional test for further confirmation of the diagnosis of PSP

    An audio and video corpus of speech addressed to 28 11-month-olds is described. The corpus allows comparisons between adult speech directed toward infants, familiar adults, and unfamiliar adult addressees as well as of caregivers' word teaching strategies across word classes. Summary data show that infant-directed speech differed more from speech to unfamiliar than familiar adults, that word teaching strategies for nominals versus verbs and adjectives differed, that mothers mostly addressed infants with multi-word utterances, and that infants' vocabulary size was unrelated to speech rate, but correlated positively with predominance of continuous caregiver speech (not of isolated words) in the input.

      Although numerous researches have been done on corpus and cognitive linguistics, only a few researches combine them together, especially in language teaching. It provides a theoretical guidance for combining corpus and cognitive linguistics in Eng⁃lish lexical teaching. Linguists should take both the frequency and cognitive theories into consideration when they decide which word should be included in the lexical syllabus because there is sometimes a difference between the frequency and the tuition. What’s more, the combination in lexical teaching can help EFL (English as a Foreign Language) learners to better deal with some common problems such as homonymy and synonymy.

    Corpus-based translation studies has grown considerably over the past fifteen years or so. This paper appraises the uniformity and diversity of descriptive corpus studies of translation in terms of divergent similarity, as intended by Andrew Chesterman (1996, 2004a, 2006). The analysis focuses on the state of the art of research into translation universals, highlighting the interdisciplinary nature of current investigations and their contribution to the progress of the discipline as a whole. The general framework proposed by Chesterman is also used to introduce an envisaged study of Anglicisms whose aim is twofold: to unveil the translation-specific lexical primings of English loan genre.

    Abstract: In this paper the writer examines problems the African Languages Lexical (ALLEX Project (at present the African Languages Research Institute (ALRI? encountered while tagging the Shona corpus. The problems to be highlighted include general problems which apply to more than one language as well as problems peculiar to Shona. The paper was inspired by the challenges the writer encountered when he took part in building the Shona corpus. An analysis of the problems that most corpus builders face shows that more problems are likely to be encountered when dealing with spoken corpora than with written corpora. The paper demonstrates that tagging is an important component of corpus building as it makes it easier for a researcher to extract relevant data. To utilise the benefits of a tagged corpus, the tagging should be thorough and accurate. Wellinformed decisions form an integral part of the tagging process since the utility of a tagged corpus depends largely on the input of the tagging process. This paper shows the need to take the tagging process seriously.

La endoscopia con biopsia gástrica y prueba de ureasa han sugerido que este dolor se relaciona con gastritis nodular asociada a infección por Helicobacter pylori (Hp. Se realizó un estudio en 66 niños entre 7 y 15 años de edad y de ambos sexos, ingresados en 9 hospitales cubanos con el objetivo de evaluar el efecto del Q-Ulcer (subcitrato de bismuto coloidal y metronidazol en pacientes con diagnóstico endoscópico de gastritis crónica asociada a infección por Hp. Se realizó endoscopia, examen histológico y evaluación clínica antes de comenzar el tratamiento y 4 semanas después de haber finalizado. En treinta y cuatro de estos pacientes se erradicó el Hp con remisión de la gastritis. De los 28 pacientes restantes 14 se incluyeron en la categoría de mejorados y 14 en la de sin respuesta, debido a que el microorganismo se mantuvo positivo, aunque en menor densidad. Los eventos adversos se presentaron en aproximadamente la mitad de los niños y fundamentalmente, durante las dos primeras semanas de tratamiento en que la terapia era combinada. Por esta razón, no se puede precisar que fuera el Q-Ulcer el único responsable de la presencia de estos síntomas, ya que a partir de la tercera semana no se presentaron con la misma frecuencia. La terapia combinada de Q-Ulcer y metronidazol garantizó una apreciable mejoría clínica, endoscópica e histológica, a la vez que resultó segura en el tratamiento de niños portadores de gastritis.

  13. How host regulation of Helicobacter pylori-induced gastritis protects against peptic ulcer disease and gastric cancer.

    Science.gov (United States)

    Dhar, Poshmaal; Ng, Garrett Z; Sutton, Philip

    2016-09-01

    The bacterial pathogen Helicobacter pylori is the etiological agent of a range of gastrointestinal pathologies including peptic ulcer disease and the major killer, gastric adenocarcinoma. Infection with this bacterium induces a chronic inflammatory response in the gastric mucosa (gastritis). It is this gastritis that, over decades, eventually drives the development of H. pylori-associated disease in some individuals. The majority of studies investigating H. pylori pathogenesis have focused on factors that promote disease development in infected individuals. However, an estimated 85% of those infected with H. pylori remain completely asymptomatic, despite the presence of pathogenic bacteria that drive a chronic gastritis that lasts many decades. This indicates the presence of highly effective regulatory processes in the host that, in most cases, keeps a check on inflammation and protect against disease. In this minireview we discuss such known host factors and how they prevent the development of H. pylori-associated pathologies.

    AIM: To investigate the expression of different cytokeratins (CKs) in gastric epithelium of adult patients with chronic gastritis infected with Helicobacter pylori(H pylori) cagA + strains.METHODS: The expression of CK 7, 8, 18, 19 and 20 was studied immunohistochemically in antral gastric biopsies of 84 patients. All the CKs were immunostained in cagA +H pylori gastritis (57 cases), non-Hpylori gastritis (17 cases) and normal gastric mucosa (10 cases).RESULTS: In cagA+ Hpylori gastritis, CK8 was expressed comparably to the normal antral mucosa from surface epithelium to deep glands. Distribution of CK18 and CK 19 was unchanged, i.e. transmucosal,but intensity of the expression was different in foveolar region in comparison to normal gastric mucosa. Cytokeratin 18 immunoreactivity was significantly higher in the foveolar epithelium of H pylori-positive gastritis compared to both Hpylori-negative gastritis and controls.On the contrary, decrease in CK19 immunoreactivity occurred in foveolar epithelium of H pylori-positive gastritis. In both normal and inflamed antral mucosa without H pylori infection, CK20 was expressed strongly/ moderately and homogenously in surface epithelium and upper foveolar region, but in H pylori-induced gastritis significant decrease of expression in foveolar region was noted. Generally, in both normal antral mucosa and H pylori-negative gastritis, expression of CK7 was not observed, while in about half cagA+ H pylori-infected patients, moderate focal CK7 immunoreactivity of the neck and coiled gland areas was registered, especially in areas with more severe inflammatory infiltrate.CONCLUSION: Alterations in expression of CK 7, 18,19 and 20 together with normal expression of CK8 occur in antral mucosa of H pylori-associated chronic gastritis in adult patients infected with cagA+ strains. Alterations in different cytokeratins expression might contribute to weakening of epithelial tight junctions observed in H pylori-infected gastric mucosa.

First, major corpus query tools such as Sketch Engine, NINJAL-NLP, Natsume, Chunagon, which can be used by learners and teachers of Japanese language, are briefly described. Focus then shifts to adjectival and nominal collocates and the resource "Collocation data of adjectives and nouns" which consists of adjective headwords and their nominal collocates extracted from two large corpora, BCCWJ and JpTenTen: 500 adjectives and 9,218 collocate nouns, and 500 adjectives and 23,220 collocate nouns from each corpus respectively. Finally, it is shown that corpus-based resources can be used in the creation of reference materials for learners of the Japanese language. The benefits of empirical research into collocations are also shown by comparing the obtained results with collocations in textbooks for Japanese as foreign language.

    Agenesis of the corpus callosum is currently diagnosed prenatally with ultrasound and MRI. While the diagnostic aspects of callosal defects are widely addressed, anatomo-histological data from fetal autopsies are sparse. Callosal defects were present in 50 fetal autopsies. Four distinct groups of complete, partial, hypoplastic, and mixed defects were determined by the gross and histologic details of the corpus callosum. These details helped to rule out other midline defects such as holoprosencephaly. Additional autopsy findings enabled specific diagnoses and suggested etiopathogeneses. Hypoplastic and mixed defects were associated with more abnormalities of the cerebral hemispheres and internal organs. The four groups did not differ according to gender, external dysmorphism, or cerebellar and brainstem anomalies. Defects were classified as syndromic (68 %), encephaloclastic (8 %), undetermined (14 %), or isolated (10 %) based on the autopsy findings. Isolated agenesis of the corpus callosum was diagnosed in only 10 % of the cases in this series, compared to higher numbers diagnosed by prenatal ultrasonography and MRI. Therefore, the autopsy, through its detailed, careful evaluation of external, as well as gross and histological internal features, can elucidate the etiopathogenesis of agenesis of the corpus callosum and suggest specific diagnoses which cannot be ascertained by prenatal imaging.

    Full Text Available PURPOSE: Hydrocephalus causes countless cerebral damages, especially on the structures around the ventricles. Hydrocephalic children present deficiencies in the nonverbal skills more than in the verbal skills, and not always revertible with an early treatment. As the corpus callosum has an important role in the nonverbal acquisition it is possible that the injuries in this structure are responsible for the cognitive dysfunctions of these children. This present study tries to establish the alterations caused by hydrocephalus on the corpus callosum of developing Wistar rats, induced by intracisternal injection of kaolin. METHODS : Seven, fourteen and twenty one days after the injection, the animals were killed, and the corpus callosum was dissected and prepared for the study of the axonal fibers. RESULTS AND CONCLUSION: The seven-day old rats in hydrocephalus development presented a delay in myelination in relation to the control rats. With the fourteen-day old rats in hydrocephalus development the corpus callosum showed a recovery of myelin, but with the twenty one-day old rats in hydrocephalus development the axonal fibers were damaged and reduced in number.

    In this longitudinal population-based study (N = 544), we investigated whether early parenting and corpus callosum length predict child executive function abilities at 4 years of age. The length of the corpus callosum in infancy was measured using postnatal cranial ultrasounds at 6 weeks of age. At 3 years, two aspects of parenting were observed: maternal sensitivity during a teaching task and maternal discipline style during a discipline task. Parents rated executive function problems at 4 years of age in five domains of inhibition, shifting, emotional control, working memory, and planning/organizing, using the Behavior Rating Inventory of Executive Function-Preschool Version. Maternal sensitivity predicted less executive function problems at preschool age. A significant interaction was found between corpus callosum length in infancy and maternal use of positive discipline to determine child inhibition problems: The association between a relatively shorter corpus callosum in infancy and child inhibition problems was reduced in children who experienced more positive discipline. Our results point to the buffering potential of positive parenting for children with biological vulnerability. PMID:24028215

    Full Text Available Selenium (Se is an essential trace element in human and animal nutrition. It is also widely utilized in industrial processes. Reports of acute selenium toxicity in humans are rare. We report a case of a 23-year-old female who consumed about 100 mL of liquid selenite broth and presented with severe nausea, vomiting, abdominal pain, hematemesis and acute renal failure (ARF. The serum selenium level was significantly increased. Gastro-duodenoscopy revealed severe corrosive gastritis. Renal biopsy showed features of acute tubular necrosis (ATN, affecting primarily the proximal tubules. The patient was managed with gastric lavage, blood transfusions, infusion of fresh frozen plasma (FFP and platelet concentrates and hemo-dialysis. The patient was discharged five weeks after admission and her renal functions reco-vered completely by eight weeks after admission. She continues to be on regular follow-up for any possible sequelae of mucosal corrosive damage. This case highlights a case of selenium intoxication from selenite broth resulting in ARF and corrosive gastritis. The recovery was complete.

    To determine the relationship between H. pylori density with severity of chronic inflammatory infiltrate. Study Design: A cross-sectional study. Place and Duration of Study: The study was carried out in the Department of Pathology (Histopathology), Army Medical College, National University of Sciences and Technology (NUST) Islamabad, from Nov 2011 to Nov 2012. Methodology: Gastric antral biopsies of H. pylori associated chronic gastritis were included in the study. Demographic characteristics and relevant clinical information were collected. First hundred biopsies of H. pylori associated chronic gastritis were assessed for density of H. pylori and chronic inflammatory infiltrate. istopathological features like lymphoid aggregates, ulcer slough, superficial epithelial damage, dysplasia and nuclear reactive changes were simply assessed in case of their presence or absence. Results: A significant moderate positive correlation was found between grades of H. pylori and chronic inflammatory infiltrate (rs= 0.636). Insignificant correlation was found with lymphoid aggregates, superficial epithelial damage, dysplasia and nuclear reactive changes. Conclusion: In conclusion this study corroborated the determination of histopathological parameters and depicted that, the greater the density of H. pylori infection, the greater the degrees of chronic inflammatory infiltrate.

    There are few data in the literature on microscopic gastritis and colitis in the pediatric population. The diagnosis is often made after the occurrence of complications. We report the case of a 10.5 year-old girl for whom the diagnosis was made several years after the initial symptoms. Test for infections, inflammation, and auto-immunity yielded normal results. Upper endoscopy and colonoscopy revealed an abnormal mucosa. However, histology showed microscopic inflammation and fibrotic lesions in the lamina propria, and a thick subepithelial collagenous band. This led to the diagnosis of collagenous gastritis and colitis. Budesonide treatment resulted in the cessation of diarrhea and significant weight gain. Treatment by oral budesonide indeed seems to be highly effective but relapses are frequent when the treatment is stopped. This case shows the importance of being vigilant regarding transit disorders with impact on growth kinetics. Upper endoscopy and colonoscopy need to be carried out when children have organic diarrhea with normal blood tests. PMID:27266639

    Full Text Available Background/Aim: Helicobacter pylori ( H. pylori infection causes peptic ulceration and gastric adenocarcinoma. In Iraq, gastric cancer is rare. We investigated whether infected adults had the antral-predominant pattern of H. pylori -associated gastritis, which does not predispose to cancer. Materials and Methods: We evaluated histopathological changes by the Sydney scoring system in gastric biopsies taken from 30 H. pylori -infected adults and studied the correlation of these changes with the virulence factors. The Mann-Whitney test was used for the comparison of histopathological data. The presence or absence of each pathological index was evaluated with respect to the possession of virulence factors by the infecting H. pylori strain using the χ2 test. Results: Gastric lymphocyte infiltration was more prominent in the antrum ( P = 0.01. Neutrophil infiltration was mild and gastric mucosal atrophy was rare. No relationship was found between virulence factors and histopathological changes. Conclusions: The mild pathology and antral-predominant gastritis help explain the low cancer rate in Iraq.

    Full Text Available In Traditional Chinese Medicine (TCM, tongue diagnosis (TD has been an important diagnostic method for the last 3000 years. Tongue coating can be used as a very sensitive marker to determine the progress of chronic gastritis. Therefore, the scientific, qualitative, and quantitative study for the pathophysiologic basis of tongue coating (TC emerged as a major direction for the objective research of TD. In our current report, we used GC/MS technology to determine the potential changes of metabolites and identify special metabolic biomarkers in the TC of H. pylori infected chronic gastritis patients. Four discriminative metabolites were identified by GC/MS between the TC of H. pylori infection (G+H and without H. pylori infection (G-H patients: ethylene, cephaloridine, γ-aminobutyric acid, and 5-pyroglutamic acid, indicating that changes in amino acid metabolism are possibly involved in the formation of TC, and the amino acid metabolites are part of the material components of TC in G+H patients.

    2014-10-01

    Russell body esophago-gastro-duodenitis is an unusual form of chronic inflammation, with only 22 cases being reported in PubMed. However, the prevalence and clinical significance remain unknown. This report describes the clinico-pathological characteristics of nine cases of Russell body gastritis (RBG) and one case of Russell body duodentitis (RBD), with nonspecific endoscopic appearance. The Mott cells (plasma cells with Russell bodies) showed κ light chain restriction in eight gastritis cases and λ light chain restriction in the duodentitis case, and there were no histological features that suggested lymphoma. Thus, a diagnosis of monoclonal RBG/RBD was made. Helicobacter pylori infection was found in 55.6% of RBG cases and in the RBD case. And, the clinical follow-up evaluations were uneventful. This report is the first study to describe this benign disease entity with monoclonality on a large-scale basis. In addition, the monoclonality of Mott cells cannot be used as evidence of an existing neoplastic lesion, and taken together, these findings may indicate a reactive process. PMID:25001185

    Full Text Available Background/Aim. Changes in the morphology and the size of the corpus callosum, are related to various pathological conditions. An analysis of these changes requires data about sexual dimorphism of the corpus callosum, which we tried to obtain in our study. We also investigated the method of digital morphometry and compared the obtained results with the results of other authors obtained by magnetic resonance imaging or by planimetry. Methods. A morphological research included 34 human brains (cadavers of both sexes − 19 female and 15 male aged 26−72 years. By digital morphometry using an AutoCAD software we performed measurements in the corpus callosum: the length (L, width in the half of its length (WW’, length of its cortical margin (LCM, area and perimeter of the anterior and posterior callosal segments, as well as the area and perimeter of the corpus callosum section area. The investigated parameters were analyzed and compared between the females and males. Results. There was not a statistically significant difference between the males and females in the investigated parameters of the corpus callosum (t test; p > 0.05, including the mean values of the two most important parameters, the surface of its midsagittal section area (males 654.11 mm2; females 677.40 mm2 and of its perimeter (males 19.61 cm; females 19.72 cm. The results obtained by digital morphometry were in the range of the results of other authors obtained by magnetic resonance and by planimetry. However, the value of Pearson coefficient of linear correlation between the section surface area and perimeter of the corpus callosum in the males was highly significant (rxy = 0.6943, p < 0.01, while in the females this value was statistically insignificant. Conclusion. Digital morphometry is accurate method in encephalometric investigations. Our results suggest that the problem of sexual dimorphism of the corpus callosum is very complex, because the identical variables (section

    2015-12-21

    The aim of this study was to identify disease-associated loci in oldest old Han Chinese with atrophic age-related macular degeneration (AMD). This genome-wide association study (GWAS) only included oldest old (≥95 years old) subjects in Rugao County, China. Thirty atrophic AMD patients and 47 age-matched non-AMD controls were enrolled. The study subjects underwent a complete ophthalmic examination. Genomic DNA was extracted from peripheral blood samples. Single nucleotide polymorphisms (SNPs) were scanned by Genome-Wide Human Mapping SNP 6.0 Arrays and GeneChip Scanner 3000 7G. The results were read and analyzed by the Affymetrix Genotyping Console software. We filtered out the SNPs with a no-call rate ≥10%, MAF P old Han Chinese population. This finding may lead to new strategies for screening of atrophic AMD for Han Chinese.

  7. Clinical endocrinological studies on the function of human corpus luteum

    International Nuclear Information System (INIS)

    Plasma progesterone (P) and estradiol-17β (E2) were measured with the radioimmunoassay (RIA), and the human corpus luteum function detected. They are investigated endocrinologically. The investigation is divided into three sections. The first section deals with a study on the function of corpus luteum menstruations. Plasma level of P was 12.6 +- 3.83 ng/ml and that of E2 was 18.9 +- 61.7 pg/ml during mid-luteal phase. Plasma levels of P during menstrual cycle in infertile woman whose BBT(basal body temperature) high phase were 12.1 +- 4.56 ng/ml for 13 days or more, and 6.82 +- 2.14 ng/ml for 11 days. Those indicate a significant difference. However, in the case of E2, there is no significant difference. Interrelation of administration was not recognized between hCG(human chorionic gonadotropin) 2,000, 3,000 and 5,000 IU. The second section deals with the function of corpus luteum graviditatis. There was no significant difference of plasma levels between P and E2 during conceptual cycles. The most active period of the corpus luteum function may be 5 - 6 weeks of gravidity, and the life of the function is considered to be about 9 - 10 weeks. The final section deals with the steroides dynamics under hCG administration for threatened abortion cases in early pregnancy. Administration of hCG up to 20,000 IU a day of normal pregnancy and threatened abortion showed remarkable increase of levels of P and E2. Exogenous hCG up to 20,000 IU a day is supposed to have no luteotropic effect on corpus luteum graviditatis. (Iwakiri, K.)

  8. A MRI quantitative study of corpus callosum in normal adults

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Objective: To investigate the possible age- and sex-related differences in the various dimensions of corpus callosum among Chinese normal adults. Methods: Magnetic resonance images of 286 healthy adults, including 127 males and 159 females, and ranging in age from 20 to 81 years, were investigated. They were classified into 5 age groups (20-29, 30-9, 40-49, 50-59, and 60-81 years old). Corresponding to the age group sequence above, the male/female ratio of each group respectively was: 25/26, 26/33, 33/50, 32/36, and 11/14. The following dimensions of corpus callosum were systematically measured on the midsagittal T1-weighted images: frontal to occipital pole (represented as line segment AB), total longitudinal dimension of the corpus callosum (CD), the maximum height (EF), the widths of the genu (CX), anterior one third (GH), central region (EZ), posterior one third (MN) and splenium (YD). After that, the obtained data was analyzed statistically. Results: (1) The total longitudinal dimension, maximum height, widths of the genu, central region and splenium were proved to be larger in females. But the widths of the anterior one third and posterior one third were similar in-between. In spite of that, a conspicuous sex-related difference was not found. (2) The total longitudinal dimension and the maximum height of the corpus callosum remained stable in all age subgroups. Yet the widths of the genu, anterior one third, central region, posterior one third and splenium had a tendency of decreasing gradually with aging. Statistical difference was seen in the anterior one third, central region, posterior one third (P<0.05). Conclusion: There is no sex-related difference in all dimensions of corpus callosum. But, with aging, a significant difference is found in the widths of the anterior one third, central region and posterior one third.

    Full Text Available We retrospectively reviewed a new preimplantation regenerative augmentation technique for a severely atrophic posterior maxilla using sinus lifting with simultaneous alveolar distraction, together with long-term oral rehabilitation with implants. We also analyzed the regenerated bone histomorphologically. This study included 25 maxillary sinus sites in 17 patients. The technique consisted of alveolar osteotomy combined with simultaneous sinus lifting. After sufficient sinus lifting, a track-type vertical alveolar distractor was placed. Following a latent period, patient self-distraction was started. After the required augmentation was achieved, the distractor was left in place to allow consolidation. The distractor was then removed, and osseointegrated implants (average of 3.2 implants per sinus site, 80 implants were placed. Bone for histomorphometric analysis was sampled from six patients and compared with samples collected after sinus lifting alone as controls (n=4. A sufficient alveolus was regenerated, and all patients achieved stable oral rehabilitation. The implant survival rate was 96.3% (77/80 after an average postloading followup of 47.5 months. Good bone regeneration was observed in a morphological study, with no significant difference in the rate of bone formation compared with control samples. This new regenerative technique could be a useful option for a severely atrophic maxilla requiring implant rehabilitation.

    Sinus floor elevation with simultaneous implant placement in severely atrophic maxilla is challenging. The aim of this retrospective study was to evaluate the short-term performance of modified osteotome sinus floor elevation (OSFE) with concentrated growth factor (CGF) application and concurrent placement of a short implant in cases with residual bone height (RBH) of 2–4 mm. Twenty-five short implants were installed in 16 patients with mean RBH of 3.23 mm using modified OSFE with CGFs from January 2012 to April 2014. Postoperatively, the implants were clinically evaluated, and vertical bone gain (VBG) was measured using cone beam computed tomography. The mean duration of follow-up was 19.88 months (12–32 months). All the implants were stable with an overall survival rate of 100%. The mean VBG immediately after surgery was 9.21 mm. Six months later, significant reduction of alveolar bone height (2.90 ± 0.22 mm) was found (P  0.05). Within the limits of this study, modified OSFE with CGF application and simultaneous short implant placement could yield predictable clinical results for severely atrophic maxilla with RBH of 2–4 mm.

    Muscle unloading due to long-term exposure of weightlessness or simulated weightlessness causes atrophy, loss of functional capacity, impaired locomotor coordination, and decreased resistance to fatigue in the antigravity muscles of the lower limbs. Besides reducing astronauts' mobility in space and on returning to a gravity environment, the molecular mechanisms for the adaptation of skeletal muscle to unloading also play an important medical role in conditions such as disuse and paralysis. The tail-suspended rat model was used to simulate the effects of weightlessness on skeletal muscles and to induce muscle unloading in the rat hindlimb. Our series studies have shown that the maximum of twitch tension and the twitch duration decreased significantly in the atrophic soleus muscles, the maximal tension of high-frequency tetanic contraction was significantly reduced in 2-week unloaded soleus muscles, however, the fatigability of high-frequency tetanic contraction increased after one week of unloading. The maximal isometric tension of intermittent tetanic contraction at optimal stimulating frequency did not alter in 1- and 2-week unloaded soleus, but significantly decreased in 4-week unloaded soleus. The 1-week unloaded soleus, but not extensor digitorum longus (EDL), was more susceptible to fatigue during intermittent tetanic contraction than the synchronous controls. The changes in K+ channel characteristics may increase the fatigability during high-frequency tetanic contraction in atrophic soleus muscles. High fatigability of intermittent tetanic contraction may be involved in enhanced activity of sarcoplasmic reticulum Ca(2+)-ATPase (SERCA) and switching from slow to fast isoform of myosin heavy chain, tropomyosin, troponin I and T subunit in atrophic soleus muscles. Unloaded soleus muscle also showed a decreased protein level of neuronal nitric oxide synthase (nNOS), and the reduction in nNOS-derived NO increased frequency of calcium sparks and elevated

    AIM: To determine the HLA-DQ locus in Mexican patients with Chronic gastritis and gastric adenocarcinoma.METHODS: Oligotyping for HLA-DQ locus was performed in 45 Mexican patients with chronic gastritis and 13 Mexican patients with diffuse-type gastric adenocarcinoma, and was then compared with 99 clinically healthy unrelated individuals. H pylori infection and CagA status were assessed in patients by enzyme-linked immunosorbent assay (ELISA) method.RESULTS: We found a significant increased frequency of HLA-DQB1*0401 allele in H pylori-positive patients with chronic gastritis when compared with healthy subjects [19 vs 0%, P = 1 × 10-7, odds ratio (OR) = 4.96; 95%confidence interval (95% CI), 3.87-6.35]. We also found a significant increased frequency of HLA-DQB1*0501 in patients with diffuse-type gastric carcinoma in comparison with healthy individuals (P = 1 × 10-6, OR = 13.07;95% CI, 2.82-85.14).CONCLUSION: HLA-DQ locus may play a different role in the development of H pylori-related chronic gastritis and diffuse-type gastric adenocarcinoma in the Mexican Mestizo population.

    Xiao-Xing Li

    Full Text Available Recent 16S ribosomal RNA gene (rRNA molecular profiling of the stomach mucosa revealed a surprising complexity of microbiota. Helicobacter pylori infection and non-steroidal anti-inflammatory drug (NSAID use are two main contributors to gastritis and peptic ulcer. However, little is known about the association between other members of the stomach microbiota and gastric diseases. In this study, cloning and sequencing of the 16S rRNA was used to profile the stomach microbiota from normal and gastritis patients. One hundred and thirty three phylotypes from eight bacterial phyla were identified. The stomach microbiota was found to be closely adhered to the mucosa. Eleven Streptococcus phylotypes were successfully cultivated from the biopsies. One to two genera represented a majority of clones within any of the identified phyla. We further developed two real-time quantitative PCR assays to quantify the relative abundance of the Firmicutes phylum and the Streptococcus genus. Significantly higher abundance of the Firmicutes phylum and the Streptococcus genus within the Firmicutes phylum was observed in patients with antral gastritis, compared with normal controls. This study suggests that the genus taxon level can largely represent much higher taxa such as the phylum. The clinical relevance and the mechanism underlying the altered microbiota composition in gastritis require further functional studies.

    Full Text Available In Corpus Linguistics and the Description of English Hans Lindquist offers another introductory book to corpus linguistics, but aims it specifically at ‘university students of English at intermediate to advanced levels who have a certain background in grammar and linguistics, but who have not had the opportunity to use computer corpora to any great extent’ (Lindquist 2009, xvi. He proposes that the book, especially certain sections of it, may also be of interest to students of literature. Corpus Linguistics and the Description of English comprises ten chapters. Chapters 1-5 cover the basics, introducing corpus linguistics as a discipline, discussing its methods and explaining key terms, while Chapter 6-10 delve into more specific and different subject matters ranging from corpus-based metaphor studies to the applications of corpora in sociolinguistics. Readers new to corpus linguistics would therefore benefit from reading the first section of the book, but might opt to peruse only chapters relevant to their studies from the second part. That said, Chapters 6-10 provide a valuable overview of the different possibilities within corpus linguistics for anyone new to the field. All chapters are set up in an identical fashion and include, in addition to a discussion of the topic covered, a chapter summary, study questions, suggestions for further reading as well as online corpus exercises on the books supplementary webpage.

    Full Text Available The capture of the public servant in a criminal investigation is subject to special rules and different to those for the capture of individuals, since the imprisonment of an official can affect continuity, speed and efficiency of the civil service, an equally important constitutional value. Therefore, as a rule capturing the public servant must be preceded by a request for suspensión by the prosecution, and to proceed without suspension, the prosecutor in his providence should motivate the reasons and arguments why not affects the normal functioning of public administration. The lack of motivation for this essential aspect, affords a fact that becomes appropriate procedural habeas corpus as an effective mechanism guarantees of personal freedom. Similarly appropriate habeas corpus when catching public server ordered by a prosecutor without functional competence to advance research, by setting a path made by organic defect.

  19. Academic lexis and disciplinary practice: corpus evidence for specificity

    2009-12-01

    Full Text Available The presence of unfamiliar words and expressions in academic texts is a serious obstacle to students reading in a second language. EAP has responded to this challenge by taking the view that there is a common core of academic vocabulary which is frequent across an academic register. This paper briefly considers this view by examining the range, frequency, collocation, and meaning of items on the Academic Word List (AWL in a large multidisciplinary corpus. Our corpus analysis shows that individual lexical items on the list often occur and behave in different ways across disciplines and that words commonly contribute to ‘lexical bundles’ which also reflect disciplinary preferences. Our findings question the widely held assumption that there is a single core vocabulary needed for academic study and suggests that teachers should assist students towards developing a more restricted, disciplinary-based lexical repertoire.

    1997-01-01

    We present the results of a study of definite descriptions use in written texts aimed at assessing the feasibility of annotating corpora with information about definite description interpretation. We ran two experiments, in which subjects were asked to classify the uses of definite descriptions in a corpus of 33 newspaper articles, containing a total of 1412 definite descriptions. We measured the agreement among annotators about the classes assigned to definite descriptions, as well as the agreement about the antecedent assigned to those definites that the annotators classified as being related to an antecedent in the text. The most interesting result of this study from a corpus annotation perspective was the rather low agreement (K=0.63) that we obtained using versions of Hawkins' and Prince's classification schemes; better results (K=0.76) were obtained using the simplified scheme proposed by Fraurud that includes only two classes, first-mention and subsequent-mention. The agreement about antecedents was al...

    2016-05-01

    Full Text Available Corpus callosum agenesis (CCA was evaluated by ultrasound examination and magnetic resonance imaging (MRI with many studies. Ultrasonography was able to suspect CCA by indirect signs but a definitive diagnosis of CCA was achieved in rare cases. MRI was able to diagnose complete CCA in majority of cases. Additional neurological abnormalities including heterotopia, gyration anomaly, asymmetry of the cerebral hemispheres, and Dandy-Walker variant were documented, as well as an ocular anomaly which was described, by MRI examination. Prenatal counseling for fetal agenesis of the corpus callosum is difficult as the prognosis is uncertain. The association with other cerebral abnormalities increases the likelihood of a poor outcome and ultrasonographic assessment of the fetal brain is limited. We found MRI to be a safe and useful additional procedure to complement ultrasonographic diagnosis or suspicion of CCA.

    Full Text Available This paper contemplates how corpus evidence might be used to address teachers' questions about English grammar and suggests that corpus linguistics has an important role to play in raising their awareness to linguistic features and patterns. The article surveys a range of grammatical questions posted by EFL/ESL teachers on four Orkut communities devoted to the teaching and learning of English. It concentrates on three specific types of questions: synonymous lexical items which function differently and are reported to be difficult to teach and explain; linguistic evidence that contradicts the prescriptive grammar rules that teachers have been taught during their education; and collocations that teachers attempt to explicate. In attempting to address the teachers' questions, corpus evidence is used to offer possible explanations. It is suggested that the use of corpus data in addressing these questions is not only convincing but also leads to discoveries of patterns and meanings which might not be found in other reference materials such as grammars and dictionariesEste artículo contempla cómo la evidencia del corpus lingüístico podría ser usado para responder preguntas de los profesores de inglés respecto de la gramática inglesa, y sugiere que el corpus lingüístico tiene un rol importante que jugar para incrementar la advertencia respecto de los patrones y aspectos lingüísticos.

    Full Text Available Abstract The synthesis of progesterone by the corpus luteum is essential for the establishment and maintenance of early pregnancy. Regulation of luteal steroidogenesis can be broken down into three major events; luteinization (i.e., conversion of an ovulatory follicle, luteal regression, and pregnancy induced luteal maintenance/rescue. While the factors that control these events and dictate the final steroid end products are widely varied among different species, the composition of the corpus luteum (luteinized thecal and granulosa cells and the enzymes and proteins involved in the steroidogenic pathway are relatively similar among all species. The key factors involved in luteal steroidogenesis and several new exciting observations regarding regulation of luteal steroidogenic function are discussed in this review.

    Mammals rely on two major pathways to transfer information between the two hemispheres of the brain: the anterior commissure and the corpus callosum. Metatheria and monotremes rely exclusively on the anterior commissure for interhemispheric transfer between the isocortices and olfactory allocortices of each side, whereas Eutheria use a combination of the anterior commissure and an additional pathway exclusive to Eutheria, the corpus callosum. Midline cross-sectional area of the anterior commissure and corpus callosum were measured in a range of mammals from all three infraclasses and plotted against brain volume to determine how midline anterior commissure area and its size relative to the corpus callosum vary with brain size and taxon. In Metatheria, the square root of anterior commissure area rises in almost direct proportion with the cube root of brain volume (i.e. the ratio of the two is relatively constant), whereas among Eutheria the ratio of the square root of anterior commissure area to the cube root of brain volume declines slightly with increasing brain size. The total of isocortical and olfactory allocortical commissure area rises more rapidly with increasing brain volume among Eutheria than among Metatheria. This means that the midline isocortical and olfactory allocortical commissural area of metatherians with large brains (about 70 ml) is only about 50% of that among eutherians with similarly sized brains. On the other hand, isocortical and olfactory allocortical commissural area is similar in Metatheria and Eutheria at brain volumes around 1 ml. Among the Eutheria, some groups make less use of the anterior commissure pathway than do others: soricomorphs, rodents and cetaceans have smaller anterior commissures for their brain size than do afrosoricids, erinaceomorphs and proboscideans. The findings suggest that use of the anterior commissural route for isocortical commissural connections may have placed limitations on interhemispheric transfer of

    2008-01-01

    Full Text Available Abstract Background Advanced Text Mining (TM such as semantic enrichment of papers, event or relation extraction, and intelligent Question Answering have increasingly attracted attention in the bio-medical domain. For such attempts to succeed, text annotation from the biological point of view is indispensable. However, due to the complexity of the task, semantic annotation has never been tried on a large scale, apart from relatively simple term annotation. Results We have completed a new type of semantic annotation, event annotation, which is an addition to the existing annotations in the GENIA corpus. The corpus has already been annotated with POS (Parts of Speech, syntactic trees, terms, etc. The new annotation was made on half of the GENIA corpus, consisting of 1,000 Medline abstracts. It contains 9,372 sentences in which 36,114 events are identified. The major challenges during event annotation were (1 to design a scheme of annotation which meets specific requirements of text annotation, (2 to achieve biology-oriented annotation which reflect biologists' interpretation of text, and (3 to ensure the homogeneity of annotation quality across annotators. To meet these challenges, we introduced new concepts such as Single-facet Annotation and Semantic Typing, which have collectively contributed to successful completion of a large scale annotation. Conclusion The resulting event-annotated corpus is the largest and one of the best in quality among similar annotation efforts. We expect it to become a valuable resource for NLP (Natural Language Processing-based TM in the bio-medical domain.

    t Aim: To investigate alterations of smooth muscle cells and collagen fibers in corpus cavernosum following cavernous neurectomy and its relation to the expression of transforming growth factor-β1 (TGF-β1). Methods: Ten adult male SD rats (neurectomy group) were subject to a bilateral cavernous nerve (CN) resection aseptically under an operating microscope, with 6 sham-operated rats as the control. Fifteen weeks after the operation, the penile specimens were collected and prepared for quantitative-analyzing of ratio of smooth muscle to collagen fibers in corpus cavernosum with confocal microscopy, and for detecting the expression of TGF-β1 by RT-PCR and westernblot.Results: Smooth muscle cells that show red color after fluorescent-labeling with tetramethylrhodamine isothiocyanatephalloidin and collagen fibers that produce green autofluorescence after paraformaldehyde fixation were clearly identified under the confocal microscope. Quantification of fluorescent intensity showed that the ratio of smooth muscle to collagen fibers in corpus cavernosum in neurectomy group was 0.265± 0.125, which was significantly lower than that in sham-operated group (0.760±0.196, P<0.01). RT-PCR and western-blot analyses revealed a significantlyhigher expression of TGF-β1 in the penile tissues of the neurectomy animals than that in sham-operated group.Conclusion: Bilateral ablation of CN can lead to fibrosis of corpus cavernosum, which may be related to an increased expression of TGF-β1 induced by hypoxia in cavernous tissue after denervation.

    Full Text Available Context: Chickenpox (varicella is a common viral disease caused by Varicella zoster virus. Facial atrophic scars after varicella infection are not uncommon and pose a cosmetic problem. Like atrophic scars of other aetiologies, they are a difficult condition to treat. There are not enough references in the literature regarding efficient treatment of post varicella scars. High strength Trichloroacetic acid (TCA, which is known to cause dermal collagen remodelling, was used to treat varicella scars in the present study. Aims: The study was undertaken to assess the efficiency of Chemical Reconstruction of Skin Scars (CROSS technique using 100% TCA in the treatment of atrophic facial post varicella scars. Settings and Design: Open label, pilot study. Materials and Methods: A total of 16 patients with atrophic facial post varicella scars were treated by focal application of 100% TCA solution by pressing down upon the scar surface by a toothpick (CROSS technique. Total 4 sittings were given at 2 weekly intervals and the results evaluated after 3 months of follow-up. Statistical analysis was carried out using Fischer′s exact t-test. Results: All of the 13 patients who completed the study showed good clinical improvement, with 69% patients grading the response as excellent (>75% improvement, whereas the rest 31% patients reporting good (51-75% improvement. No significant complications were seen in any patient. Conclusions: CROSS technique using 100% TCA is a safe, cheap and effective therapy for the treatment of post varicella scars.

  13. Annotated chemical patent corpus: a gold standard for text mining.

    Saber A Akhondi

    Full Text Available Exploring the chemical and biological space covered by patent applications is crucial in early-stage medicinal chemistry activities. Patent analysis can provide understanding of compound prior art, novelty checking, validation of biological assays, and identification of new starting points for chemical exploration. Extracting chemical and biological entities from patents through manual extraction by expert curators can take substantial amount of time and resources. Text mining methods can help to ease this process. To validate the performance of such methods, a manually annotated patent corpus is essential. In this study we have produced a large gold standard chemical patent corpus. We developed annotation guidelines and selected 200 full patents from the World Intellectual Property Organization, United States Patent and Trademark Office, and European Patent Office. The patents were pre-annotated automatically and made available to four independent annotator groups each consisting of two to ten annotators. The annotators marked chemicals in different subclasses, diseases, targets, and modes of action. Spelling mistakes and spurious line break due to optical character recognition errors were also annotated. A subset of 47 patents was annotated by at least three annotator groups, from which harmonized annotations and inter-annotator agreement scores were derived. One group annotated the full set. The patent corpus includes 400,125 annotations for the full set and 36,537 annotations for the harmonized set. All patents and annotated entities are publicly available at www.biosemantics.org.

Šolar’s data gave insight into the whole range of linguistic problems associated with the use of two forms and allowed for the subject of the study, i.e. ‘full verb + infinitival complement’ structures, to be precisely defined. The following section describes the method used to compile a shortlist of high-frequency full verbs co-occurring with infinitival complements from the half-million-word, morphosyntactically and syntactically annotated training corpus that was created within the Communication in Slovene project. Finally, the co-relation between genre, mode and the use of the two forms is examined in detail; based on a quantitative analysis of data extracted from corpora of written (FidaPLUS and spoken language (GOS for each full verb on the shortlist, new findings on the actual use of the short and long infinitive in both written and spoken texts are presented.

    Numerous corpora lutea form from the multiple follicles that ovulate during the oestrous cycle of pigs. Vascular elements invade the follicle from the theca compartment, first centripetally, and subsequently by lateral branching of centripetal veins and arteries. The vessels are the vehicle for dispersion of steroidogenic theca cells throughout the corpus luteum. Mitosis occurs in both the theca and granulosa layers before ovulation, and in luteal cells well into the luteal phase. Luteal cell proliferation undergoes gradual restriction as the corpus luteum matures, but the mechanisms of exit from the cell cycle are unknown. The extracellular ligands that direct luteinization and maintain the corpus luteum include LH, prolactin, insulin and insulin-like growth factors (IGFs). These ligands induce qualitative and quantitative changes in steroid output, with progesterone as the principal product. These changes upregulate the cholesterol synthetic pathways to increase substrate availability. The intracellular regulation of luteinization is complex. A model is presented in which LH stimulates arachidonic and lineoleic acid metabolism to produce ligands for the nuclear proteins of the peripheral peroxisome activator receptor family. These ligands have downstream effects on cell differentiation and exit from the cell cycle. Luteal function is maintained by interactions among ligands, cholesterol regulatory proteins and constitutively expressed and regulated transcription factors. PMID:11980202

  16. MR measurement of normal corpus callosum: Age and sex differentiation

    International Nuclear Information System (INIS)

    Measurement of various portions of the corpus callosum was performed on magnetic resonance(MR) images of 114 subjects with no known or suspected corpus callosal disorders. Midsagittal T1-weighted images used for measurements and mean diameters of various portions in each age and sex group were obtained. Measures of five portions were made: (A) the anterio-posterior length, (B) the diameter of genu position, (C) the diameter of splenium, (D) the diameter of mid-body portion, (E) the diameter of a narrow portion at the body of corpus callosum. The mean diameter in each gender group for A, B, C, D and E were 68.8 mm, 12.1 mm, 12.3 mm, 6,9 mm, 4.1 mm in male and 69.9 mm, 12.0 mm, 12.1 mm, 6.4 mm, 4.1 mm in female, retrospectively.

    H pylori is now accepted as the cause of gastritis and gastritis-associated diseases, such as duodenal ulcer,gastric ulcer, gastric carcinoma, and gastric MALT lymphoma. The natural history of H pylori gastritis includes inflammation progressing from the antrum into the adjacent corpus resulting in an atrophic front of advancing injury leading to a reduction in acid secretion and eventual loss of parietal cells and development of atrophy. Sub-typing intestinal metaplasia has no clinical value to the patient, the pathologist, or the endoscopist.The pattern, extent, and severity of atrophy, with or without intestinal metaplasia, is a far more important predictor than is intestinal metaplasia subtype. The challenge remains to identify a reliable marker that relates to pre-malignant potential.

    Full Text Available Las hazañas trascendentales alcanzadas por la gastroenterología en los últimos cien años han sido mere-cedoras de tres premios Nobel de Medicina y apreciadas por millones de pacientes con úlcera alrededor del mundo. En 1904 Pavlov es premiado por describir los mecanismos neuro-reflejos de la secreción del ácido clorhídrico y en 1988 el equipo de Black por el descubrimiento de los antagonistas de los receptores H2 de histamina. De manera inesperada Marshall y Warren, dos investigadores clínicos australianos reciben el Premio Nobel en el año 2005 por encontrar que el Helicobacter pylori está relacionado con la patogénesis de la gastritis y úlcera péptica. Las investigaciones posteriores a los descubrimientos de Pavlov complementan el conocimiento de la fisiología gástrica al describir los componentes hormonales (gastrina y humorales (histamina de la secreción gástrica. Se propone que la úlcera péptica es consecuencia del exceso de ácido clorhídrico en el estómago y el planteamiento realizado por Schwartz en 1910 guiará el tratamiento de la úlcera péptica durante muchos años. Sin ácido no hay úlcera. La cirugía con sus diversas técnicas de vagotomía no logra el control de la úlcera péptica. Este fracaso impulsa a los farmacólogos a profundizar en el conocimiento de los mecanismos de control hormonal y humoral de la secreción gástrica. Como resultado se desarrollan los medicamentos que bloquean los receptores H2 expresados por las células parietales del estómago, los cuales al ser activados, inducen a las células a producir ácido. Es irónico que Sir James W. Black ganara el Premio Nobel de Medicina en 1988 por el descubrimiento de estos receptores. Su trabajo preparó el camino para el desarrollo de los bloqueadores H2 de histamina y los inhibidores de la bomba de protones. Tales drogas cambiaron el manejo de la enfermedad y finalmente la cirugía quedó limitada a los casos de perforación gástrica. De

    The implant-supported fixed rehabilitation of patients with an atrophic edentulous crest remains a challenge if bone augmentation is not planned. A minimal intervention approach for bone regeneration is necessary to minimize the flap overextension needed to close the defect over the augmented bone. Prosthetically guided bone regeneration can determine the amount of bone augmentation necessary for definitive prosthetic fixed rehabilitation. The positions of the implants and prosthetic restoration were planned; a 0.3 mm thick titanium mesh was customized for bone augmentation by using computer-aided design and computer-aided manufacturing and rapid prototyped by laser sintering, and the definitive prosthetic rehabilitation was carried out according to the initial treatment plan. This resulted in minimal bone augmentation relative to the functional needs of the definitive prosthetic rehabilitation. PMID:25862269

    Collagenous gastritis is a rare condition characterized by surface epithelial damage, subepithelial collagen deposition, and a lamina propria inflammatory infiltrate. Previous studies have proposed 2 clinicopathologic subtypes: (1) children (18 y of age or younger) presenting with severe anemia, nodular gastric mucosa, and isolated gastric disease; and (2) adults with chronic watery diarrhea that is associated with diffuse collagenous involvement of the gastrointestinal tract. However, notable exceptions exist. In fact, broad variability in clinical presentation, etiology, treatment and disease course has been reported. To better define the clinicopathologic features of collagenous gastritis, we have collected 10 pediatric and 21 adult cases and describe their clinical, endoscopic, pathologic, and follow-up findings. Both children and adults presented with similar clinical symptoms such as anemia (50%, 35%, respectively), epigastric/abdominal pain (50%, 45%), and diarrhea (40%, 55%). Concomitant immune disorders were identified in 2 (20%) children and 3 (14%) adults. Further, 7 of 17 (41%) adults were taking medications associated with other immune-related gastrointestinal diseases including olmesartan and antidepressants. Histologically, there were no differences between children and adults with collagenous gastritis in the location of gastric involvement, mean collagenous layer thickness, and prominence of eosinophils (P>0.05). Extragastric collagenous involvement was also seen with comparable frequencies in each cohort (44%, 59%). Follow-up information was available for 22 of 31 (71%) patients and ranged from 2 to 122 months (mean, 33.6 mo). Despite medical management in most cases, persistence of symptoms or collagenous gastritis on subsequent biopsies was seen in 100% of children and 82% of adults. Of note, treatment for 1 adult patient involved cessation of olmesartan resulting in resolution of both symptoms and subepithelial collagen deposition on subsequent

    Full Text Available Although corpora have been used in language teaching for some time, few empirical studies explore their impact on learning outcomes. We provide a microgenetic account of learners’ responses to corpus-driven instructional units for German modal particles and pronominal da-compounds. The units are based on developmental corpus data produced by native speakers during interactions with the very learners for whom the units are designed. Thus, we address the issue of authentication in corpus-driven language pedagogy. Finally, we illustrate how an ethnographically supplemented developmental learner corpus may contribute to second language acquisition research via dense documentation of micro-changes in learners’ language use over time.

    2009-10-01

    Full Text Available Abstract Background Information Extraction (IE is a component of text mining that facilitates knowledge discovery by automatically locating instances of interesting biomedical events from huge document collections. As events are usually centred on verbs and nominalised verbs, understanding the syntactic and semantic behaviour of these words is highly important. Corpora annotated with information concerning this behaviour can constitute a valuable resource in the training of IE components and resources. Results We have defined a new scheme for annotating sentence-bound gene regulation events, centred on both verbs and nominalised verbs. For each event instance, all participants (arguments in the same sentence are identified and assigned a semantic role from a rich set of 13 roles tailored to biomedical research articles, together with a biological concept type linked to the Gene Regulation Ontology. To our knowledge, our scheme is unique within the biomedical field in terms of the range of event arguments identified. Using the scheme, we have created the Gene Regulation Event Corpus (GREC, consisting of 240 MEDLINE abstracts, in which events relating to gene regulation and expression have been annotated by biologists. A novel method of evaluating various different facets of the annotation task showed that average inter-annotator agreement rates fall within the range of 66% - 90%. Conclusion The GREC is a unique resource within the biomedical field, in that it annotates not only core relationships between entities, but also a range of other important details about these relationships, e.g., location, temporal, manner and environmental conditions. As such, it is specifically designed to support bio-specific tool and resource development. It has already been used to acquire semantic frames for inclusion within the BioLexicon (a lexical, terminological resource to aid biomedical text mining. Initial experiments have also shown that the corpus may

    In this paper we propose a new method in which a text corpus is used as the source of knowledge in conjunction with a machine learning method to find matching between two ontologies .The main objective in this new method is to find similarity of two concepts based on similarity of their instances. We show how contextual knowledge hidden in domain specific documents can help us to boost the machine learning methods by providing enough features. Also we show how taking benefit from this knowledge transcends the current approaches merely detect lexical similarity by either recognizing semantic similarity of concepts.

    Full Text Available Electroconvulsive Therapy (ECT is a powerful treatment option in severe or chronic catatonic states and has been reported to be useful in oligophrenic patients. We report the followup medical history of a patient with corpus callosum aplasia (or agenesis who was continuously treated with ECT over three years. First, he improved considerably after a series of ECT, but relapses of catatonia made a continuous, weekly ECT necessary. Due to the severity of the brain malformation, an add-on medication with benzodiazepines and second generation antipsychotics was necessary to treat catatonic symptoms. This case emphasises the benefits of long-term ECT in oligophrenic patients.

    Emotion words play a vital role in many sentiment analysis tasks. Previous research uses sentiment dictionary to detect the subjectivity or polarity of words. In this paper, we dive into Emotion-Inducing Keywords (EIK), which refers to the words in use that convey emotion. We first analyze an emotion corpus to explore the pragmatic aspects of EIK. Then we design an effective framework for automatically detecting EIK in sentences by utilizing linguistic features and context information. Our system outperforms traditional dictionary-based methods dramatically in increasing Precision, Recall and F1-score.
