    Full Text Available The stomach is one of the most common organs in which mucosa-associated lymphoid tissue (MALT lymphoma develops. It is well established that Helicobacter pylori (Hp infection plays a major role in the development of gastric MALT lymphoma and that the presence of Hp in the gastric mucosa is connected with mucosa-associated lymphatic tissue (MALT.The same tissue is located in the oral cavity and pharynx in Waldayer’s circuit. Recently, the oral cavity was proposed as an extragastric reservoir of Hp infection. We report the case of a 79-year-old female patient with concomitant pharyngeal (MALT lymphoma and Hp-related gastric MALT lymphoma. Gastric MALT lymphoma was detected both through endoscopic examination as well as in biopsies. Pharyngeal MALT lymphoma was also detected in biopsies. Hp has been recognized in the gastric mucosa by positive serum H. pylori antibody and urease tests. Treatment of the Hp infection in our patient using antibiotics led to the regression of both lesions. This is the first case report on the regression of a pharyngeal MALT lymphoma after Hp eradication.

    Gastric non-Hodgkin lymphoma is a rare tumour that represents approximately 7% of all stomach cancers and 2% of all lymphomas. The most frequent location of gastric MALT (mucosa associated lymphoid tissue) lymphomas is in the antrum in 41% of the cases, and 33% can be multifocal. The risk of spontaneous perforation of a gastric MALT lymphoma is 4-10%. 24 year old male patient carrying the Human Immunodeficiency Virus, who began with signs and symptoms of acute abdomen and fever 72 hours before arriving in the emergency room. A computed tomography was performed that showed free fluid in the cavity, and gastric wall thickening. The patient underwent a laparotomy, finding absence of the anterior wall of the stomach, sealed with the left lobe of the liver, colon and omentum. Total gastrectomy, with oesophagosty and jejunostomy tube, was performed. Gastric perforation secondary to a MALT lymphoma is rare, with high mortality. There is limited information reported of this complication and should be highly suspected in order to provide appropriate treatment for a complication of this type.

    AIMS: Gastric MALT (mucosa-associated lymphoid tissue) lymphoma is now recognized as a distinct entity within extranodal non-Hodgkin's lymphoma. The purpose of this study was to describe the radiographic findings in low grade gastric MALT lymphoma. MATERIALS AND METHODS: We retrospectively reviewed the radiographic findings in 22 cases of low-grade gastric MALT lymphoma. The study group consisted of 15 men and seven women (median age 68 years, range 41-91 years). Lesions were designated as infiltrative or polypoid by consensus of two radiologists. Polypoid lesions were categorized by number and size. Anatomical site within the stomach and presence of transpyloric or oesophagogastric extension was determined for each case. The presence of abdominal lymphadenopathy was categorized as regional or distant. The presence of Helicobacter pylori was determined from endoscopic and surgical biopsies. RESULTS: Computed tomography (CT) revealed abnormalities of the stomach in 19 cases of the 21 in which it was performed. There were 14 infiltrative lesions and five polypoid lesions. Of the 14 infiltrative lesions, the mean gastric wall thickness was 2.2 cm (range 0.8-6.0 cm). There were three single and two multiple polypoid lesions (mean size 2.2 cm, range 1.5-2.7 cm). Transpyloric extension was observed in two cases and oesophagogastric extension in one. Abdominal lymphadenopathy was observed in 10 of 21 patients. Helicobacter pylori was found in 19 of 22 cases (86%). CONCLUSION: Low grade B cell gastric MALT lymphomas present with an infiltrative form on CT in about three-quarters of cases and a polypoid pattern in the remainder. Abdominal lymphadenopathy is seen in approximately one-half of cases. There is a high association with Helicobacter pylori. Brown, J.A. 2000. Clinical Radiology 55, 384-389

    Gastric MALT lymphoma is a distinct entity related to Helicobacter pylori gastritis. Some studies suggest a role for trisomy 3 in the genesis of these lymphomas, but they mainly focused on low-grade MALT lymphoma. Gastric MALT lymphoma, however, comprises a spectrum from low- to high-grade cases.

    The aim of the study was to evaluate the usefulness of 18 F-FDG-PET in patients with gastric lymphoma, in particular those affected by mucosa-associated lymphoid tissue (MALT) type and aggressive gastric non-Hodgkin's lymphoma (NHL). The study group consists of 15 patients with a previous diagnosis of gastric NHL referred to our PET centres in Bologna Hospital and Rovigo Hospital, Italy, in the period 2003-2004. In 9/15 patients the subsequent histological evaluation was consistent with a gastric MALT lymphoma, while aggressive gastric NHL was diagnosed in the other 6/15. PET scan was carried out in patients with known active disease in order to stage or re-stage disease prior to treatment or in patients in complete clinical remission to monitor disease during follow up. Patients were considered in complete clinical remission if free from disease for at least 8 months after chemotherapy or surgery. 18 F-FDG PET was performed following standard procedures. 18 F-FDG-PET was true positive in all cases of gastric MALT and non-MALT aggressive NHL with known active disease, while no pathological 18 F-FDG uptake was evident in the subjects who were in complete clinical remission. The degree of 18 F-FDG uptake (mean SUVmax values) in MALT lymphoma was much less intense in comparison to aggressive gastric NHL, suggesting a prognostic role of SUV calculation in gastric lymphomas. Our data demonstrate the significant accuracy of 18 F-FDG-PET in detecting active disease in gastric lymphoma of both MALT and non-MALT NHL type. A higher SUV value appears to be related to a more aggressive disease. (author)

    Full Text Available Context Gastric mucosa-associated lymphoid tissue (MALT lymphoma is clearly associated with Helicobacter pylori gastritis and can be cured with anti- H pylori therapy alone. The presence of t(11;18(q21;q21 translocation is thought to predict a lower response rate to anti- H pylori treatment. Objectives To study the presence of t(11;18(q21;q21 genetic translocation and its clinical impact in low-grade gastric MALT lymphoma Brazilian patients. Methods A consecutive series of eight patients with gastric MALT lymphoma were submitted to gastroscopy, endoscopic ultrasound, histopathological examination, H pylori search and RT-PCR-based methodology. All patients received anti-H pylori treatment. Eradicated patients were followed-up every 3-6 months for 2 years. Results Eight patients were studied. All patients had tumor involvement restricted to the mucosa or submucosa and seven patients had low-grade gastric MALT lymphoma. All infected patients achieved H pylori eradication. Histological tumor regression was observed in 5/7 (71% of the low-grade gastric MALT lymphoma patients. The presence of t(11;18(q21;q21 translocation was found in 4 (57% of these patients; among them only two had histological tumor regression following H pylori eradication. Conclusions RT-PCR is a feasible and efficient method to detect t(11;18(q21;q21 translocation, being carried out in routine molecular biology laboratories. The early detection of such translocation can be very helpful for better targeting the therapy to be applied to gastric MALT lymphoma patients.

    Full Text Available Background/Aim. Lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma of the stomach usually occurs as a consequence of Helicobacter pylori (H. pylori infection. The aim of this study was to investigate the long-term effect of treatment of low-grade gastric MALT lymphoma with the H. pylori eradication method. Methods. In the period 2002-2012 in 20 patients with dyspepsia, mean age 55.1 years, the endoscopic and histologic diagnosis of gastric MALT lymphoma in the early stages were made. Histological preparations of endoscopic biopsy specimens were stained with hematoxyllineosin (HE, histochemical and immunohistochemical methods. Results. Endoscopic findings of gastritis were documented in 25% of the patients, and 75% of the patients had hypertrophic folds, severe mucosal hyperemia, fragility, nodularity, exulcerations and rigidity. Histopathologically, pathognomonic diagnostic criterion were infiltration and destruction of glandular epithelium with neoplastic lymphoid cells, the so-called lymphoepithelial lesions. In all 20 patients H. pylori was verified by rapid urease test and Giemsa stain. After the triple eradication therapy complete remission of MALT lymphoma was achieved in 85% of the patients, with no recurrence of lymphoma and H. pylori infection in the average follow-up period of 48 months. In 3 (15% of the patients, there was no remission of MALT lymphoma 12 months after the eradication therapy. Of these 3 patients 2 had progression of MALT lymphoma to diffuse large-cell lymphoma. Conclusion. Durable complete re-mission of low-grade gastric MALT lymphoma is achieved in a high percentage after eradication of H. pylori infection, thus preventing the formation of diffuse large-cell lymphoma and gastric adenocarcinoma.

    Mucosa-associated lymphoid tissue (MALT) lymphomas represent a relatively new described class of rare lymphomas, characterized by an indolent course and favourable outcome with specific therapy. Gastric MALT lymphomas are associated with chronic Helicobacter pylori (HP) infection. We report the case of a 67 year old man admitted for an 8-month history of epigastric pain, anorexia and progressive weight loss. He was diagnosed with low-grade primary gastric MALT lymphoma by endoscopy, histopathological examination of gastric mucosa (light microscopy and immunohistochemistry) and endoscopic ultrasonography (EUS). The patient received a 2-week course of anti-HP therapy and chemotherapy with Chlorambucil 0.1 mg/kg/day was started. During the follow-up, continuous improvement of clinical status, endoscopic and EUS appearance was noted. We conclude that, facing the trend toward nonsurgical treatment modalities for primary gastric lymphoma, EUS appears an important tool for staging the disease and defining cases suitable for anti-HP, radio- and chemotherapy, as well as for the detection of local recurrence.

    A 68-year-old Japanese woman underwent radiotherapy for gastric lymphoma. Although lymphangiectasia was sparsely observed in the second portion of the duodenum before radiotherapy, the number of pinpoint white spots obviously increased after the treatment. Although the duodenal lymphangiectasia gradually progressed, the patient had no features of protein-losing enteropathy. This case highlights the importance of endoscopic observation of the duodenum after irradiation to the abdomen as radiotherapy may secondarily cause intestinal lymphangiectasia. PMID:28798810

    The role of 18F-FDG-PET/CT in evaluating gastric MALT lymphoma is still controversial. In the literature the detection rate of 18F-FDG-PET/CT in patients with gastric MALT lymphoma is variable, and the reason for this heterogeneity is not still clear. Our aim was to investigate the particular metabolic behavior of these lymphoma. Sixty-nine patients (26 female, 43 male) with histologically confirmed gastric MALT lymphoma who underwent a 18F-FDG-PET/CT for initial staging from two centers were included. The PET images were analyzed visually and semi-quantitatively by measuring the maximum standardized uptake value (SUVmax), lesion-to-liver SUVmax ratio, and lesion-to-blood pool SUVmax ratio and compared with Ann Arbor stage, epidemiological (age, sex), histological (presence of gastritis, ulcer, H. pylori infection, plasmacytic differentiation, Ki-67 index), and morphological (tumor size, superficial lesions or mass-forming) characteristics. Thirty-six patients (52 %) had positive PET/CT (average SUVmax was 9±6.7; lesion-to-liver SUVmax ratio 3.7±2.6, lesion-to-blood pool SUVmax ratio 4.8±3.3) at the corresponding gastric lesion; the remaining 33 were not 18F-FDG-avid. In the univariate analysis, 18F-FDG avidity was significantly associated with morphological features (mass forming p<0.001 and high maximum diameter p<0.001), Ann Arbor stage (p=0.010), and Ki67 index (p<0.001) and not correlated with age, sex, presence of gastritis, ulcer, Helicobacter pylori infection, and plasmacytic differentiation. In the multivariate analysis, the correlations with gross morphological appearance, Ann Arbor stage, and Ki-67 score were confirmed. SUVmax, lesion-to-liver SUVmax ratio, and lesion-to-blood pool SUVmax ratio correlated significantly only with Ki67 index (p=0.047; p=0.012; p=0.042). 18F-FDG avidity was noted in 52 % of gastric MALT lymphoma and this avidity is correlated with gross morphological characteristics, tumor stage, and Ki-67 index.

    In most H. pylori-positive patients, gastric low-grade mucosa-associated lymphoid tissue (MALT) lymphomas regress both endoscopically and histopathologically after H. pylori eradication, but no factors that can be predictive of the response to the eradication have been definitively identified, and there is little information on how to determine the optimal observation period before additional treatment can be started. Here, clinical studies dealing with the diagnosis and treatment of gastric MALT lymphomas and H. pylori published during the last 5 years were systematically reviewed, and studies identifying the molecular approaches involved in the pathogenesis were summarized. Most of the clinical studies indicate a favorable effect of H. pylori eradication on the clinical outcome of gastric MALT lymphomas. Some studies suggest the necessity of additional treatment in nonresponders to H. pylori eradication, while others suggest the adoption of a watch-and-wait strategy. The molecular characteristics of MALT lymphomas could play an important role in prognostic prediction and the selection of further therapeutic intervention after the eradication. This updated review of gastric MALT lymphomas illustrates the potential efficacy of H. pylori eradication in tumor remission, but further molecular characterization is necessary to establish the most suitable therapeutic strategy for patients who do not respond to eradication.

    Over the last years, our knowledge on pathogenesis of gastric MALT lymphoma has greatly improved, but its morphological diagnosis is still hampered by overlapping histological features with advanced chronic gastritis. MicroRNAs are deregulated in lymphomas, but their role and usefulness in gastric MALT lymphoma has not been extensively investigated. We analyzed the expression of 384 miRNAs using TaqMan microRNA assay in a training series of 10 gastric MALT lymphomas, 3 chronic gastritis and 2 reactive lymph nodes. Then, significantly deregulated miRNAs were individually assessed by real-time PCR in a validation series of 16 gastric MALT lymphomas and 12 chronic gastritis. Gastric MALT lymphoma is characterized by a specific miRNA expression profile. Among the differentially expressed miRNAs, a significant overexpression of miR-142-3p and miR-155 and down-regulation of miR-203 was observed in gastric MALT lymphoma when compared to chronic gastritis. miR-142-3p, miR-155 and miR-203 expression levels might be helpful biomarkers for the differential diagnosis between gastric MALT lymphomas and chronic gastritis.

    Objective: In recent years, a large proportion of non-Hodgkin's lymphomas of the stomach are recognized as low grade tumors of the mucosa associated lymphoid tissue (MALT) type. Since the MALT morphological subtype has only gained acceptance as a malignant lymphoma after the establishment of the Working Formulation, there is limited information about its natural history, disease pattern, and longterm treatment outcome. This study is an analysis of these parameters in patients with primary MALT lymphoma of the stomach. Materials and Methods: Consecutive patients with primary gastric MALT lymphoma who received definitive treatment at the Massachusetts General Hospital between (4(78)) and (2(95)) were included in the study. The diagnosis was pathologically verified in all cases. Clinical staging studies included chest X-ray +/- chest CT, abdomino-pelvic CT or bipedal lymphangiogram, barium swallow, and bone marrow biopsy. Treatment strategies included combinations of partial or total gastrectomy, radiation (RT) and chemotherapy (chemo). RT was given via multifield technique, with 10-25MV photons, to doses of 36-50.4 Gy (1.1-1.8 Gy per fraction, 5 days a week). Survival analyses were performed by the Kaplan-Meier actuarial method. Results: There were twenty-two patients between the ages of 45 - 93 years, with a mean follow-up of 67 months. Ten were male and 12 female. The most frequent presenting symptoms were epigastric pain (77%), dyspepsia (65%), and melena (41%). The mean duration of symptoms was 27 months. Eighteen cases were clinical stage (cs)I, two csII, one csIII, and one csIV. The treatment approaches were: 1) csI:6 gastrectomy alone, 7 gastrectomy and RT, 1 gastrectomy and chemo, 2 RT alone, 1 chemo and RT, 1 no therapy; 2) csII: 2 gastrectomy and RT; 3) csIII: 1 gastrectomy and chemo; 4) csIV: 1 chemo and RT. Among 16 gastrectomy specimens, multifocal gastric involvement was evident in 50%. The most frequently involved sites were the body (63%) and antrum

    Full Text Available The aim of this study was to investigate the Lewis antigen expression in Helicobacter pylori gastric MALT lymphoma associated strains in comparison to chronic gastritis only strains. Forty MALT strains (19 cagPAI (- and 21 cagPAI (+ and 39 cagPAI frequency-matched gastritis strains (17 cagPAI (- and 22 cagPAI (+ were included in this study. The lipopolyssacharide for each strain was extracted using a hot phenol method and the expression of Le(x and Le(y were investigated using Western Blot. The data were analyzed according to the strains' cagPAI status and vacA genotype. Le(x was identified in 21 (52.5% MALT strains and 29 (74.3% gastritis strains. Le(y was identified in 30 (75% MALT strains and 31 (79.5% gastritis strains. There was an association between cagPAI positivity and Le(x expression among MALT strains (p<0.0001, but not in gastritis strains (p = 0.64. Among cagPAI (- strains, isolates expressing solely Le(y were associated with MALT with an odds ratio of 64.2 (95% CI 4.9-841.0 when compared to strains expressing both Le(x and Le(y. vacA genotypes did not modify the association between Lewis antigen expression and disease status. In conclusion, cagPAI (- MALT strains have a particular Lewis antigen profile which could represent an adaptive mechanism to the host response or participate in MALT lymphomagenesis.

    Full Text Available Introduction: endoscopic ultrasonography (EUS has already proven useful in the assessment of submucosal lesions, and the staging of gastrointestinal cancer, particularly gastric MALT-type lymphoma. The goal of this paper was EUS staging. Patients and method: 24 patients (10 females, 14 males with a median age of 56 years and possibly gastric MALT lymphoma (25 cases were studied using videoendoscopy, biopsies, and echoendoscopy with 7.5- and 20-MHz radial EUS, and also with 12- and 20-MHz miniprobes (MPs. Nineteen patients were definitely evaluated (7 females, 12 males as having 20 MALT-type lymphomas, as five patients were post-hoc disregarded when an invasive, high-grade gastric lymphoma (3c or plasmocytoma (2c was subsequently demonstrated. Of these 19 patients, all had T1 lesions except for two with T2 lesions; one patient had a gastroduodenal T1 lymphoma. Echographic findings with MPs were compared to EUS (gold standard and histology both before and after eradication. Then, patients were followed up every 1-3-6 months using videoendoscopy and MPs. Results: echoendoscopy correctly identified T stages in 90% of cases. MPs identified T stages in 88% of cases, and N stages in 33% of cases, with results being slightly inferior to those obtained with conventional EUS (91 vs. 45%; they were consequently used for follow-up. After eradication, all but two patients are in complete remission and have been followed every 1-3-6 months using MPs without echographic abnormalities, except for a patient who relapsed.Introducción: la ultrasonografía endoscópica (USE ha demostrado ya su utilidad en la evaluación de las lesiones submucosas, en la estadificación del cáncer digestivo en general, y del linfoma gástrico tipo MALT en particular.

    Although eradication of Helicobacter pylori and radiation therapy (RT) have curative potential for gastric mucosa-associated lymphoid tissue (MALT) lymphoma, no prospective study has yet been reported. This prospective study evaluated the efficacy and safety of this non-surgical treatment for localized gastric MALT lymphoma. Among the 115 eligible patients, 89 (77.3%) achieved remission with eradication therapy. Twenty five (21.7%) patients received RT as additional treatment for residual tumor and 22 (88%) achieved complete remission. No serious adverse events, such as hemorrhage or perforation of the stomach, were observed. This organ-preserving treatment for localized gastric MALT lymphoma is safe and effective and has the potential to become the standard treatment for this disease, although long-term follow up is necessary.

    An 80-year-old man was referred to Shinshu University Hospital in April 2001 for treatment of gastric mucosa-associated lymphoid tissue (MALT) lymphoma. He had received anti-biotic therapy in spite of no evidence of H. pylori infection in the former hospital 3 years ago, but no remarkable improvement was recognized and endoscopic findings were progressive. An esophagogastroduodenoscopy (EGD) revealed mucosal redness on the greater curvature and the anterior wall of the body. Biopsy specimens taken from the lesions showed remarkable infiltration of atypical small lymphocytes, and this lesions were diagnosed MALT lymphoma by an immunophenotypic studies. Endoscopic ultrasonography (EUS) showed that MALT lymphoma was limited within the mucosa and submucosa. Staging work up revealed stage I. After written informed consent, he was treated by 30 Gy radiation therapy for gastric MALT lymphoma. Response assessment was performed by EGD, EUS, and biopsy specimens, and a complete remission was confirmed. After that, he was followed up with regular intervals, and EGD was performed every 6 months. He was diagnosed to have O I type cardiac cancer at 21 months after radiation therapy. He underwent proximal partial gastrectomy, and histopathological findings showed as follows: O I type, 17 x 12 mm, tub 2, SM, ly 1, v 1, n 0, PM (-), DM (-), INFγ, stage I A. No residual lesion of gastric MALT lymphoma and no dysplasia of gastric mucosa was recognized. Causal relationship between radiation therapy and carcinogenesis in this case is unclear. However, it might be suggested by the facts that cancer occurred in the radiation field where MALT lymphoma had been presented and gastric cancer was rare in the stomach without H. pylori infection.

    To clarify the clinical features of gastric mucosa-associated lymphoid tissue (MALT) lymphoma (GML) with persistent lymphoma after eradication therapy of Helicobacter pylori (H. pylori), and the outcome of long-time follow-up study after treatment against GML, seventy-six patients with localized GML were studied. The median follow-up period was 44.4 months. Thirty-eight of 49 patients (77.6%) with H. pylori-positive GML had been cured of GML by antibiotic therapy alone. On the other hand, none of 13 patients with H. pylori-negative GML had been cured by antibiotic therapy (77.6% vs 0%, p<0.001). ''H. pylori-negative'' is one of the clinical features of antibiotic-resistant cases with GML. There was no significant difference in sex, age, stage, endoscopic finding, depth, and affected region between the two groups of cured and persistent GML with H. pylori infection. Twenty-two of 29 patients (75.6%) with antibiotic-resistant or H. pylori-negative cases of GML had been cured by 30 Gy radiation therapy. Low-dose radiation was thought to be a useful therapeutic procedure as a second line treatment'' of localized GML. (author)

    Extranodal marginal-zone lymphoma of mucosa-associated lymphoid tissue of the stomach (gastric MALT lymphoma) is derived from memory B cells of the marginal zone. Normal memory B cells do not express markers of germinal-center B cells, such as E2A (immunoglobulin enhancer-binding factor E12/E47), B-cell chronic lymphocytic leukemia/lymphoma 6 (BCL6), or activation-induced cytidine deaminase (AID). E2A is a transcription factor that induces somatic hypermutations and blocks plasma cell differentiation. In 50 stage-I(E)/II(E1) gastric MALT lymphomas, we confirmed that all cases were BCL6(-)/AID(-), but a subset (50%, 25/50) was E2A(+). As E2A(-) and E2A(+) gastric MALT lymphomas had similar numbers of somatic hypermutations without intraclonal variations, which implied an origin from memory B cells, the expression of E2A was best regarded as a marker of aberrant follicular differentiation. Although the status of somatic hypermutation was not affected by E2A, E2A(+) gastric MALT lymphoma showed less plasmacytoid infiltrates and higher expressions of miRNA-223, a microRNA associated with memory B cells. Clinically, E2A(+) gastric MALT lymphomas were more likely to spread to perigastric lymph nodes and were less responsive to Helicobacter eradication therapy than were E2A(-) gastric MALT lymphomas. Taken together, aberrant E2A expression is a diagnostic feature of a subtype of gastric MALT lymphoma with weaker plasmacytoid infiltrates and stronger miR-223 expression. A prospective study would be necessary to verify the association between E2A expression and a poor response to Helicobacter eradication therapy.

    The coexistence of gastric cancer with duodenal ulcer has been found empirically to be rare, but why it is rare is difficult to explain satisfactorily. To elucidate this question, we carried out a literature review of the subject. The frequency with which the two diseases coexist is 0.1-1.7%, and the main factor associated with both gastric cancer and duodenal ulcer is Helicobacter pylori infection. However, there are marked differences between the disorders of hyperchlorhydria in duodenal ulcer, and hypochlorhydria in gastric cancer. The most acceptable view of the reason for the difference may be that the acquisition of H. pylori infection occurs mainly in childhood, so that the time of acquisition of atrophic gastritis may be the most important, and if atrophic gastritis is not acquired early, high levels of gastric acid may occur, and consequently acute antral gastritis and duodenal ulcer may occur in youth, whereas, in elderly individuals, persistent H. pylori infections and the early appearance of atrophic gastritis may be the causes of low gastric acid, and consequently gastric cancer may occur. In patients with duodenal ulcer, factors such as nonsteroidal anti-inflammatory drugs (NSAIDs) and dupA-H. pylori strains may contribute to preventing the early acquisition of atrophic gastritis, while acid-suppressive therapy and vascular endothelial growth factor and other entities may inhibit atrophic gastritis. In contrast, in gastric cancer, factors such as excessive salt intake, acid-suppressive therapy, polymorphisms of inflammatory cytokines, and the homB-H. pylori strain may contribute to the early acquisition of atrophic gastritis, while factors such as NSAIDs; fruits and vegetables; vitamins A, C, and E; and good nutrition may inhibit it.

    Full Text Available Gastric choriocarcinoma is a rare neoplasm and usually accompanies gastric adenocarcinoma. The prognosis is poor due to the aggressive course of the disease. A 57-year-old female patient with weight loss and abdominal pain was examined. The patient was operated following the examination, and pathological analysis revealed the presence of a gastric adenocarcinoma associated with choriocarcinoma. Immunohistochemical analysis showed a positive reaction with antibodies to beta-human chorionic gonadotropin and overexpression of the cErbB2 proto-oncogene. Staging revealed multiple metastases in the liver. A complete response was obtained with a combination of trastuzumab and chemotherapy. The diagnosis of gastric choriocarcinomas without pathological examination is difficult due to their rare occurrence. A complete response can be obtained with trastuzumab in the treatment of cases with overexpression of the cErbB2 protein.

    Full Text Available Objective: to perform a retrospective review of the clinical characteristics and prevalence of H. pylori infection in patients with gastric MALT lymphoma diagnosed in our hospital during the last 15 years. Methods: patients with gastric MALT lymphoma diagnosed in our hospital during the last 15 years were retrospectively included. Demographic, clinic, analytic, endoscopic, and histological variables were reviewed. The extension study, the staging classification, and the presence of H. pylori infection were assessed. Results: thirty-seven patients with gastric MALT lymphoma were identified. Mean age was 61 years, with 62% of males. The most common presentation symptom was dyspepsia (76%, followed by digestive bleeding (11% and constitutional syndrome (8%. At endoscopy, erosive lesions were identified in 41%, and proliferative or exophytic lesions in 43%. Most lymphomas were classified as low-grade (68%. The stage distribution was EI for 56%, EII for 13%, EIII for 3%, and EIV for 28%. The prevalence of H. pylori infection (histology in all cases, rapid urease test in 19%, and 13C-urea breath test in 24% was 46%. When only low-grade lymphomas in stage EI were considered, H. pylori prevalence increased to 55%. When H. pylori infection was evaluated by 13C-urea breath testing (in addition to histology, the prevalence of H. pylori infection increased to 78%. Conclusions: it is probable that the reduced H. pylori prevalence found in some studies, as in ours, could be explained by false-negative results obtained when only one diagnostic method was used. Therefore, at least two (invasive diagnostic methods should be performed. Furthermore, the performance of a non-invasive diagnostic method (such as a 13C-urea breath test before the exclusion of H. pylori infection should be considered.Objetivo: revisar retrospectivamente las características clínicas y la prevalencia de infección por H. pylori en los pacientes con linfoma MALT gástrico diagnosticados

    Borderline ovarian tumors (BOTs) represent a heterogeneous group of ovarian epithelial neoplasms. Despite a favorable prognosis, 10-20% of BOTs exhibit progressively worsening clinic. Primary involvement of pelvic organs with echinococcus is very rare. Lymphoepithelioma-like gastric carcinoma is a rare neoplasm of the stomach. A 58-year-old woman referred with abdominal swelling and gastric complaints. Imaging studies revealed a huge cystic mass with multiple septations and solid component, another cystic mass with an appearance of cyst hydatid in the pelvis, and thickening of the small curvature of stomach. Gastroscopy revealed an ulcer with a suspicious malignant appearance, and histology of the endoscopic specimen showed severe chronic inflammation and lymphocytic infiltration. No other involvement of hydatid cyst was detected. In the exploration, there was a 25cm cystic lesion with solid components arising from right ovary, another 6cm cyst over the former, 7cm cystic lesion arising from left ovary, and 10cm mass near the small curvature of the stomach. Excision of the masses; total gastrectomy with esophagojejunal anastomosis; total abdominal hysterectomy; bilateral salpingo-oophorectomy; omentectomy; appendectomy; splenectomy; and pelvic, paraaortic, and coeliac lympadenectomy were performed. Final pathology revealed lymphoepithelioma-like gastric carcinoma, bilateral serous BOT, and hydatid cyst. Hydatid cyst should always be considered in the differential diagnosis of abdominopelvic masses in endemic regions of the world. Preoperative diagnosis of primary pelvic hydatid disease is difficult and awareness of its possibility is very important especially in patients residing in or coming from endemic areas.

    Mucosa-associated lymphoid tissue (MALT) lymphoma is a low-grade lymphoma that differs from high-grade non-Hodgkin lymphoma both clinically and histologically. The CT appearances of MALT lymphoma are described. Of 40 patients referred with biopsy-proven MALT lymphoma, only seven had not had gastrectomy or chemotherapy prior to CT examination. The CT scans of these seven cases were analysed for the degree and extent of gastric wall thickening, enlargement of abdominal and extra-abdominal lymph nodes, and presence of extranodal disease. In all patients the stomach was distended with oral contrast medium and scans performed at narrow collimation, after intravenous administration of 20 mg hyoscine butylbromide. In six patients focal thickening of the gastric wall was 1 cm or less. One patient had thickening of over 4 cm. There was no enlargement of abdominal or extra-abdominal lymph nodes or extension to adjacent organs. Thus on CT, at presentation, MALT lymphoma results in minimal gastric wall thickening, unlike high-grade non-Hodgkin lymphoma, which typically causes bulky gastric disease, nodal enlargement and extension into adjacent organs. CT is therefore of limited value in monitoring response to treatment. With disease greater than minimal thickening, transformation to a higher grade should be considered. (orig.)

    The broad category of non-Hodgkin's lymphoma includes a large variety of different diseases including indolent as well as aggressive lymphomas. Mucosa-associated lymphoid tissue (MALT) lymphoma arises in the extranodal mucosal lymphoid tissue and has only been recognised as a distinct entity in recent years. It affects one or several extranodal structures such as the stomach, the lung, the eye and salivary glands. The lymphoma is generally of low grade and has indolent course. The aim of this article is to exemplify the most common radiological patterns of MALT lymphoma. (orig.)

    Purpose: To evaluate the feasibility of real-time, real-anatomy tracking and gating for gastric lymphoma patients treated with magnetic resonance image-guided radiation therapy (MR-IGRT) Methods: Over the last 2 years, 8 patients with gastric lymphoma were treated with 0.3-T, Co-60 MR-IGRT. Post-treatment analysis of real-time cine imaging in the sagittal plane during each patient’s treatment revealed significant motion of the stomach. While this motion was accounted for with generous PTV margins, the system’s capability for real-time, real-anatomy tracking could be used to reduce treatment margins by gating. However, analysis was needed for the feasibility of gating using only the single available sagittal imaging plane. While any plane may be chosen, if the stomach moves differently where it is not being observed, there may potentially be a mistreatment. To that end, imaging with healthy volunteers was done to ascertain stomach motion over 2–4 min by analyzing multiple parallel sagittal and coronal planes 0.75 cm apart. The stomach was contoured on every slice, and the mean displacement between pairs of contour centroids was used to determine the amount of overall motion. Results: The mean displacement of the centroid in the image plane was 4.3 ± 0.7 mm. The greatest observed motion was more medial with respect to the patient, and less motion laterally, which implies that gating on a plane located closer to MRI isocenter will provide the more conservative scenario as it will turn the radiation delivery off when the stomach is observed to move outside a predetermined boundary. Conclusion: The stomach was observed to move relatively uniformly throughout, with maximum extent of motion closer to where most MRI systems have the best spatial integrity (near isocenter). Analysis of possible PTV margins from the healthy volunteer study (coupled with previous patient data on interfraction volumetric stomach deformation) is pending.

    Epstein-Barr virus-associated gastric carcinoma (EBVaGC) frequently harbors dense lymphocytic infiltration, suggesting a specific microenvironment allowing coexistence with tumor immunity. CD47, which mediates the "do not eat me" signal in innate immunity, is also important in adaptive anti-tumor immunity. We investigated the significance of CD47 in EBVaGC compared with EBV-negative gastric cancer and the correlation with various immune cells. By immunohistochemistry of CD47, high, low, and negative expression was observed in 24, 63, and 12% of EBVaGC (n = 41), while 11, 49, and 39% of EBV-negative gastric cancer (n = 262), respectively, indicating that high expression of CD47 in cancer cells was significantly frequent and increased in EBVaGC (P = 0.043). In contrast to EBV-negative gastric carcinoma in which no significant correlation was observed between CD47 and survival, high expression of CD47 correlated significantly with worse disease-specific survival (P = 0.011) and overall survival (P = 0.013) in EBVaGC. To further clarify the role of CD47 expression in EBVaGC, digital image analysis of immune cell infiltration revealed that high CD47 expression was correlated with a lower ratio of CD8 + /Foxp3 + T cells (P = 0.021), a sensitive indicator of tumor immunity. Thus, CD47 lowers anti-tumor immunity in EBVaGC by finely tuning profile of infiltrating T cells, suggesting that CD47 is an additional target for cancer immunotherapy against this virus-driven gastric cancer.

    Orbital mucosa-associated lymphoid tissue (MALT) lymphoma is an uncommon disease, while the incidence is recently increasing. We describe the F-18 fluorodeoxyglucose positron emission tomography computerized tomography (FDG PET/CT) findings in a case of bilateral orbital MALT lymphomas with a coexisting gastric lesion. Although only the lesion in the left orbit was initially identified on MR imaging, FDG PET/CT scan unexpectedly and additionally could identify the tiny lesion of the contralateral orbit and the gastric lesion. This patient received radiotherapy to all these lesions, with a combination of rituximab monoclonal antibody therapy. The follow-up PET/CT studies at 3, 6, and 9 months and 1.5 years after treatment showed regression or disappearance of all these FDG-avid lesions. Accurate localization and staging are crucial to select an adequate treatment in MALT lymphoma at any location. This case indicates the feasibility of FDG PET/CT scan for accurate localization and staging and also for monitoring treatment in patients with orbital MALT lymphoma.

  17. Mutation breeding in malting barley

    The released varieties of malting barley through mutation breeding is more than ten in number, including foreign varieties. In Japan four varieties has been released so far. We started mutation breeding in 1956 together with cross breeding that we employed before. Until now, Gamma 4, Amagi Nijo 1 and Fuji Nijo 2 have been produced from the direct use of induced mutations and Nirasaki Nijo 8 from the indirect use of them. Mutation breeding has been used mainly in the partial improvement of agronomic characteristics since the selection for malting quality was very complicated. As the variety bred by induced mutation is usually equivalent to the original variety in malting quality, both this new variety and the original one could be cultivated in the same area without any problem on later malt production. Particularly when one farmer cultivates barley in an extensive acreage, he can harvest at the best time according to the different maturing time of each variety. From these points of view, mutation breeding is an efficient tool in malting barley breeding. Mutagens we have used so far are X-rays, ..gamma..-rays, neutron and chemicals such as dES. From our experience in selection, the low dose of radiation and chemical mutagens are more effective in selection of point mutation than the high dose of radiation which tends to produce many abnormal but few practical mutants.

  18. Molecular Pathogenesis of MALT Lymphoma

    2015-01-01

    Full Text Available Approximately 8% of all non-Hodgkin lymphomas are extranodal marginal zone B cell lymphoma of mucosa associated lymphoid tissue (MALT, also known as MALT lymphoma, which was first described in 1983 by Isaacson and Wright. MALT lymphomas arise at a wide range of different extranodal sites, with the highest frequency in the stomach, followed by lung, ocular adnexa, and thyroid, and with a low percentage in the small intestine. Interestingly, at least 3 different, apparently site-specific, chromosomal translocations and missense and frameshift mutations, all pathway-related genes affecting the NF-κB signal, have been implicated in the development and progression of MALT lymphoma. However, these genetic abnormalities alone are not sufficient for malignant transformation. There is now increasing evidence suggesting that the oncogenic product of translocation cooperates with immunological stimulation in oncogenesis, that is, the association with chronic bacterial infection or autoaggressive process. This review mainly discusses MALT lymphomas in terms of their genetic aberration and association with chronic infections and summarizes recent advances in their molecular pathogenesis.

    Mucosa-associated lymphoid tissue (MALT) type lymphoma arises from extranodal marginal zone B-cell. It is etiologically associated with Helicobacter pylori infection and, hence, can be cured by antibiotic treatment. MALT type lymphoma is the most common variety of gastric lymphoma that is rare in the stomach). The published data of clinical studies on the usefulness of 18F-FDG PET in the diagnosis of MALT type lymphoma varied according to authors. Thus, the result of Hoffmann et al. was discouraging whereas a high diagnostic accuracy was reported by Ambrosini et al. The latter group further went to suggest that higher 18F-FDG uptake in gastric MALT type lymphoma would positively relate to the aggressiveness of neoplasm. The clinical studies conducted by other groups on MALT lymphomas of the stomach, lung, orbit and parotid gland and the stomach, lung, parotid gland, skin, orbit, mandible, esophagus and uterus confirmed that 18F-FDG scan is valuable

    Heat pumps have halved the energy costs of producing finished malt at two of the country's maltsters. The fuel-fired kilning processes described are now performed by heat pumps with considerable energy and production benefits at the maltings of J.P. Simpson and Co. (Alnwick) Ltd, in Tivetshall St Margaret, Norfolk, and of Munton and Fison Plc of Stowmarket, Suffolk. The heat pump system installed at the Station Malting of J.P. Simpson was devised by the Electricity Council Research Centre at Capenhurst near Chester. Energy cost benefits of Pound 6,000 a month are being realised at Simpsons, but there is the added benefit that the system has been designed to provide conditioned air to the germination cycle to ensure that the correct temperature is maintained throughout the year. At the Cedars factory of Munton and Fison, heat pumps were used on a trial basis for plant micropropagation and for a fish farming unit.

Woman 61 years old with antecedents of vitiligo, gastric ulcus, cirrhosis by VHC, that go into the hospital by sudden disnea, thoracic paint with pleural characterises and fever of 38.5 degrees C, Her thorax radiography and thoracic TAC showed nodes that affect to different pulmonary lobes. The cytology by PAAF confirms their malignant nature. In subsequent radiological controls it was notice the nodels took away completely and returns in different pulmonary place in each recurrence. The presentation like fluctuant pulmonary nodes is exceptional in a MALT lymphoma. It was described a higher incidence of VHC infection and tumour. The evidence of chronic hepatitis by virus C disease, and local chronic inflammatory process as well as autoimmune disorders may be considerate like a factor that contribute to MALT lymphoma.

El presente estudio muestra un paciente masculino con aumento de volumen bilateral de ambas glándulas parótidas y diagnóstico citohistopatológico de un proceso linfoepitelial benigno, el cual desarrolló un linfoma tipo MALT en relación con la glándula parótida derecha.The lymphomas type MALT or the mucosa-associated lymphoid tissue, are the most recent variety of non-Hodgkin lymphomas present mainly in the gastric mucosa associated with Helycobacter pylori infection and in the thyroid gland in relation to Hashimoto's thyroiditis. Frequently the origin of this lesion can't be determined only by cytology study, thus it is necessary the histopathology analysis for a definitive diagnosis in most cases. Present paper includes the case of male patient with bilateral volume increase of both parotid glands and a diagnosis cytopathological of a benign lymphoepithelial process and the development of a type MALT lymphoma in relation to the right parotid gland.

    Malt is a preferred base for fermentations that produce beer or whisky. Barley for malt is grown under diverse environments in different geographical locations. Malt provides an ecological niche for a varied range of microorganisms with both positive and negative effects on its quality for brewing. Little information exists in the literature on the microbial community structure of Australian malt as well as broader global geographical differences in the associated fungal and bacterial communities. The aims of the present study were to compare the bacterial and fungal community structures of Australian commercial malt with its international counterparts originating from different geographical regions using terminal restriction fragment length polymorphism (TRFLP) fingerprinting and clone library analyses of ribosomal RNA genes. Further, the relationship between malt associated microbial communities and conventional malt quality parameters was also compared. Results showed that differences in fungal communities of malts from different geographical location were more pronounced than bacterial communities. TRFLP analysis discriminated high quality commercial malts with low fungal loads from malts deliberately infected with fungal inocula (Fusarium/Penicillium). Malt moisture, beta-amylase, α-amylase and limit dextrinase contents showed significant correlations with fungal community structure. This investigation concluded that fungal community structure was more important to subsequent malt quality outcomes than bacteria. Copyright © 2015 Elsevier B.V. All rights reserved.

    The mechanisms promoting malignant transformation from chronic Helicobacter pylori-gastritis to gastric extranodal marginal zone lymphoma (MALT lymphoma) are insufficiently characterized. This follow-up study aimed to validate candidate microRNAs (miRs) in the process of neoplastic transformation. MicroRNA expression signatures (n=20) were generated for a total of 60 cases of gastric lesions ranging from Wotherspoon 0-5 employing a quantitative real-time polymerase chain reaction (PCR) approach. Morphological and immunohistochemical characterization of the cohort was supplemented by PCR-based immunoglobulin heavy chain recombination studies. Quantitative expression of miR-150, miR-142.3p, miR-375 and miR-494 was significantly de-regulated in samples from MALT lymphoma compared to those from gastritis. The previously reported up-regulation of miR-150 in marginal zone lymphoma of MALT type was verified in an independent cohort of lymphoma samples employing a modified methodology. This further substantiates the role of miR-150 as a potential oncomiR in MALT lymphoma.

    Mucosa-associated lymphoid tissue (MALT) type lymphoma arises from extranodal marginal zone B-cell. It is etiologically associated with Helicobacter pylori infection and, hence, can be cured by antibiotic treatment. MALT type lymphoma is the most common variety of gastric lymphoma that is rare in the stomach). The published data of clinical studies on the usefulness of 18F-FDG PET in the diagnosis of MALT type lymphoma varied according to authors. Thus, the result of Hoffmann et al. was discouraging whereas a high diagnostic accuracy was reported by Ambrosini et al. The latter group further went to suggest that higher 18F-FDG uptake in gastric MALT type lymphoma would positively relate to the aggressiveness of neoplasm. The clinical studies conducted by other groups on MALT lymphomas of the stomach, lung, orbit and parotid gland and the stomach, lung, parotid gland, skin, orbit, mandible, esophagus and uterus confirmed that 18F-FDG scan is valuable.

    Mucosa-associated lymphoid tissue (MALT) lymphoma and reactive inflammatory lymphoid changes are frequently difficult to distinguish based on a routine histological differential diagnosis. We were unable to diagnose gastric MALT lymphoma histologically using specimens obtained by endoscopy, although a flow cytometry (FCM) analysis demonstrated clonality of neoplastic cells by separating cells by CD45 gating. Furthermore, a fluorescence in situ hybridization (FISH) analysis showed trisomy 18. We therefore diagnosed gastric MALT lymphoma with trisomy 18. We recommend that FCM and FISH analyses of biopsy specimens be considered for diagnosing gastric MALT lymphoma if this diagnosis is suspected based on endoscopic findings.

    Between 2000 and 2007, 17 patients with localized gastric lymphoma (10 mucosa-associated lymphoid tissue lymphomas and 7 diffuse large B-cell lymphomas) were treated with radiotherapy alone or doxorubicin-based chemotherapy followed by radiotherapy. Radiation dose of mucosa-associated lymphoid tissue (MALT) lymphoma was 30 Gy with a daily fraction size of 1.5 Gy. Sixteen patients achieved complete remission and the 5-year overall survival of MALT lymphoma and diffuse large B-cell lymphoma (DLBCL) were 100% and 87%, respectively. No gastric perforation and hemorrhage were noticed. Using AP/LR 2-port radiotherapy markedly decreased the liver dose. (author)

    2003-01-01

    We report on the case of a 86-year-old male patient with a rapidly growing nodule within the right lobe of the thyroid gland, which after hemithyroidectomy, turned out to be a mucosa-associated lymphoid tissue (MALT) lymphoma of the thyroid gland. In addition, Hashimoto's thyroiditis was reported in the thyroid tissue adjacent to the MALT lymphoma. During follow-up a second nodule emerged within the left lobe and, because of evidence of MALT lymphoma recurrence, F-18-FDG-PET was performed. F-18-FDG-PET imaged a clearly in-creased accumulation within the whole left lobe and isthmus. Thus, no differences in the degree of hypermetabolism could be imaged between the nodule and the adjacent thyroid tissue. To our knowledge, this is the first report about F-18-FDG-PET in a patient with MALT lymphoma of the thyroid. Literature search revealed only a few cases of MALT lymphomas in locations other than the thyroid gland that were studied with F-18-FDG-PET. In no case was F-18 FDG accumulation seen in the MALT lesions. However, clear F-18 FDG accumulation was reported in some patients with Hashimoto's thyroiditis. It is concluded that the intensive F-18-FDG accumulation within the whole left lobe and isthmus of the presented case was due to the coexisting Hashimoto's thyroiditis. Consequently, F-18-FDG-PET imaging does not seem to be indicated in a patient with MALT lymphoma and known Hashimoto's thyroiditis in order to evaluate the status of the MALT lymphoma. (author)

  18. THE MALT EXTRACT, RELATIVE EXTRACT AND DIASTATIC POWER AS A VARIETAL CHARACTERISTIC OF MALTING BARLEY

    Directory of Open Access Journals (Sweden)

    Štefan Dráb

    2014-02-01

    Full Text Available Malting quality of barley depends on genetic and agro-ekological factors. Chemical composition of malting barley and its technological parameters are very important for malting and brewing, due to this fact the quality of barley must be strictly evaluated. The aim of this work was to evaluate the influence of variety, locality and year of production on the 5 technological parameters of malt: extract, relative extract at 45 °C, Kolbach index, diastatic power and friability. It was found out that the barley variety significantly influenced the following parameters: extract, relative extract and diastatic power. The growing locality weakly influenced qualitative parameters i.e. Kolbach index and relative extract at 45°C. The study confirmed the most significant impact of the year on the Kolbach index and friability.

    Full Text Available The simultaneous association of gastric carcinoma with omental mucosa-associated lymphoid tissue (MALT lymphoma is a rare event that has not been reported previously. We focused on the hypothetic pathogenetic mechanisms, diagnosis and treatment of this rare condition. A 55-year-old woman with Helicobacter pylori infection underwent distal gastrectomy in our hospital. Three independent early gastric cancers and a mass near the cecum were diagnosed preoperatively. Pathological review of the resected stomach showed three independent early signet ring cell gastric carcinomas, and the mass in the omentum near the cecum was shown to be omental MALT lymphoma. Due to the nature of the patient's disease, she was started on medical eradication of H. pylori. Synchronous gastric adenocarcinoma and omental MALT lymphoma is a rare event. Special attention given to H. pylori-associated gastric cancer patients can avoid misdiagnosis and lead to adequate treatment.

    Full Text Available Primary non-Hodgkin’s lymphoma (NHL of the breast constitutes 0.04%-0.53% of all malignancies and 2.2% of extra nodal lymphomas. In total, 7%-8% of all B-cell lymphomas are the mucosa-associated lymphoid tissue (MALT type, of which up to 50% of primary gastric MALT lymphoma. Herein we present a patient with breast MALT lymphoma that transformed to diffuse large B-cell lymphoma (DLBCL. A 69-year-old female presented with a mass on her left breast. Physical examination showed a 3 × 3-cm mass located 1 cm from the areola on the upper lateral quadrant of the breast at the 1 o’clock position, which was fixed and firm. Excisional biopsy was performed and pathologic examination of the specimen showed MALT lymphoma transformation to DLBCL. The patient was staged as II-EA. The rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP protocol was scheduled as treatment. Following 6 courses of R-CHOP, 2 additional courses of rituximab were administered. Positron emission tomography (PET-CT was done at the end of the treatment. PET showed that the patient was in complete remission. At the time this report was written, the patient was being followed-up at the outpatient clinic on a regular basis. Lymphoma of the breast is a rarity among malignant tumors of the breast. The most common type of lymphoma is DLBCL. Breast MALT lymphoma is extremely rare. Primary MALT lymphoma of the breast can transform from low grade to high grade and recurrence is possible; therefore, such patients should be monitored carefully for transformation.

  2. Breeding of proanthocyanidin free malting barley

    1990-01-01

    Full text: Haze formation in stored beer is due to colloidal precipitation of proteins with polyphenols of which proanthocyanidins are the most important group. 70-80% of proanthocyanidin in beer are from barley malt. Today breweries attain haze stability by using enzymes, additives or adsorbents. A better solution would be to remove proanthocyanidins. Carlsberg Plant Breeding uses induced mutations to breed proanthocyanidin-free malting barley. After mutagen treatment with sodium azide M1 seeds are planted in the field and M2 seeds are harvested in bulk. A single seed, non-destructive method has been developed to identify mutant kernels lacking proanthocyanidins in the testa. The method involves the inclusion of M2 seeds - 50 at a time - in semisolid clay blocks, whereafter a small part of the endosperm, testa and pericarp are exposed by sanding the seeds. The clay block is then placed in a vanillin-HCI solution so that the uncovered tissues can react with the solution. A red colour will develop in the testa of normal seeds, whereas the testa layers of proanthocyanid-free seeds remain colourless. So far, more than 600 mutants have been induced in over 100 barley varieties, spring as well as winter-types, from barley producing areas around the world. The mutants can be assigned to at least 7 loci, all of which can block the biosynthetic pathway for the proanthocyanidins. Mutants in the ant-18 and ant-19 loci show poor kernel development. Only a few mutants are known in the ant-12, ant-22 and ant-25 loci. Breeding work is focussed on mutants belonging to the ant-13 and ant-17 loci. Whereas the malting quality of ant-17 lines suffer from apparent abnormal enzyme development in the aleurone layer, this defect does not exist in ant-13 lines. Brewing trials with proanthocyanidin-free malt have shown excellent haze stability without changes in beer flavour. Breeding work based on the ant-13 lines led to disease resistant lines with good malting quality, while grain yield

Barley irradiated with doses up to 75 Krad produced normal malts when compared to the controls. Irradiation doses of 125 and 250 Krad significantly increased the malt yields but considerably decreased the α-amylase activity.

    Little is known about the fate of Fusarium mycotoxins during the barley malting process. To determine the fungal DNA and mycotoxin concentrations during malting, we used barley grain harvested from field plots that we had inoculated with Fusarium species that produce type A or type B trichothecenes or enniatins. Using a recently developed multimycotoxin liquid chromatography-tandem mass stable isotope dilution method, we identified Fusarium-species-specific behaviors of mycotoxins in grain and malt extracts and compared toxin concentrations to amounts of fungal DNA in the same samples. In particular, the type B trichothecenes and Fusarium culmorum DNA contents were increased dramatically up to 5400% after kilning. By contrast, the concentrations of type A trichothecenes and Fusarium sporotrichioides DNA decreased during the malting process. These data suggest that specific Fusarium species that contaminate the raw grain material might have different impacts on malt quality.

    Fifteen patients with primary gastric malignant lymphoma who underwent radiotherapy were examined. Median age was 68 years, and male to female ratio was 1:2. All the cases were stage I including 7 cases of diffuse large B-cell lymphoma (DLBCL), 7 cases of MALT lymphoma, and 1 case of follicular lymphoma. Therapy methods were as follows. For DLBCL, 30 Gy of radiotherapy was performed after chemotherapy. For six cases of MALT lymphomas, 30 Gy of radiotherapy was performed. For one patient diagnosed as high-grade gastric MALT lymphoma was treated in the same way as DLBCL. For one patient with follicular lymphoma, 30 Gy of radiotherapy was performed. The radiotherapy was applied with 3-dimensional fixed multi-portal irradiation, with the reduced irradiation of the liver and kidney. There was no recurrence of disease in all cases, and all patients have been alive, and no-recurrence living periods are 20 to 120 months. There was no harmful adverse event, and the tumor had disappeared with 30 Gy of radiation therapy in all cases. Considering the occurrence of secondary cancer, it was considered that a dosage of more than 30 Gy was not necessary for primary gastric malignant lymphoma. (J.P.N.)

    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.

    of "lymphoepithelial lesions". There are usually less reactive follicles than in low-grade lymphoma. High-grade MALT-lymphoma is macroscopically characterized by predominantly infiltrative-ulcerative lesions of stomach and gastric ulcer defects up to 4-5 cm in diameter. Histologically there is a significant number of atypical centroblast-like and immunoblast-like cells (sometimes polynuclear, numerous figures of mitosis and apoptotic bodies are found. The main immunophenotypic feature of the MALT-lymphoma is the presence of diffuse immunocell infiltration by CD20+, IgM+, IGD-B-cells outside the mantle zone of reactive follicles. Immunophenotype of tumor MALT-lymphoma cells is identical to the immunophenotype of marginal zone B-cells, the reaction with antibodies against CD5, CD10 and CD23 is negative. The comparison of expression of CD20 and CD3 antibodies has the differential-diagnostic value: predominance of CD20-positive B-cells over CD3-positive T-cells indicates a violation of immunarchitectonics which is observed in lymphomas. When reactive (nonmalignant processes are present T-lymphocytes predominate over B-lymphocytes in lymphoid cell infiltrate or they are in equal proportion. An important feature is the coexpression of BCL-2 and T-cell marker CD43 by B-cells. It was described the molecular and genetic disorders, as well as the stages of stomach MALT-lymphoma to select the method of patient’s treatment.

    Objective was to present a histopathologic and immunohistochemical analysis of primary gastric lymphomas that was reclassified according to the new World Health Organization classification of lymphoid neoplasms. We reviewed the morphological and immunohistochemical features of 28 patients with gastric lymphomas, diagnosed in the Department of pathology at the University Hospital of Tishreen University, Lattakia, Syria, during the period 1994-2003. Specimens were obtained from endoscopic and surgical biopsies. The immunohistochemical study was performed to analyze the immunophenotype of these lymphomas. Patients were aged 17-71 years. There was a slight predominance of females (male to female ratio, 13:15). Seventeen of the patients had tumors mainly located in the gastric antrum. Histologically, the most common lymphoma was of mucosa-associated lymphoid tissue (MALT) type (20 patients), also with diffuse large B-cell lymphoma (7 patients) and anaplastic large cell lymphoma (one patient). Our study demonstrates the different patterns of gastric lymphomas in Lattakia, Syria during a 10-year period in 28 Syrian patients, and reveals that the most primary gastric lymphomas are B-cell MALT lymphomas.

    Sjogren's syndrome is a chronic inflammatory disease that predominantly affects salivary, lacrimal, and other exocrine glands. We report a case of Sjogren's syndrome combined with MALT (mucose associated lymphoid tissue) lymphoma which occurred in the parotid gland. A 57-year-old female with the complaint of painful swelling and lymph node enlargement was referred to our department. Sialograms of both parotid glands showed globular collections of contrast material uniformly distributed throughout the parotid gland. Salivary scintigraphy showed decreased uptake of the parotid gland. CT scan showed larger, slightly more dense parotid gland than normal and honeycomb glandular appearance. Also, It showed discrete, slightly more enhanced round mass in the left parotid gland. Histopathological finding showed replacement of salivary gland parenchyma with dense small lymphocytic infiltration having the feature of epimyoepithelial islands. Kappa light chain restriction of interglandular plasma cell could be seen.

    Full Text Available Fungi were isolated and identified in two samples of winter two-row barley (SSK3 and SSK6 harvested in 2003, Kragujevac location, during micromalting. Fungi were isolated and identified in barley before the micromalting, after the 1st, 2nd and 3rd day of steeping, the first day and after the germination after kilning and after malt degermination. The total fungi count was followed in both barley samples, during the mentioned phases. The total count of fungi was also determined in the steeping water, and the isolation and identification was performed after the steeping process. Change of the total count of fungi during barley micromalting was exponentional. During barley micromalting nine fungi genera were isolated: Phoma, Alternaria, Fusarium aspergillus, Cladosporium, Geotrichum, Scopulariopsis, Aureobasidium and Mucor. The most frequent genera were: Phoma, Alternaria and Fusarium. In water for steeping, five genera were identified: Geotrichum, Fusarium, Phoma Cladosporium and Mucor. The most frequent genera was Phoma.

    The Great Western Malting Company recently constructed a barley malting facility in Pocatello, Idaho, designed to produce 6.0 million bushels per year of brewing malt. This facility uses natural gas to supply the energy for germination and kilning processes. The escalating cost of natural gas has prompted the company to look at alternate and more economical sources of energy. Trans Energy Systems has investigated the viabiity of using geothermal energy at the new barley processing plant. Preliminary investigations show that a geothermal resource probably exists, and payback on the installation of a system to utilize the resource will occur in under 2 years. The Great Western Malting plant site has geological characteristics which are similar to areas where productive geothermal wells have been established. Geological investigations indicate that resource water temperatures will be in the 150 to 200/sup 0/F range. Geothermal energy of this quality will supply 30 to 98% of the heating requirements currently supplied by natural gas for this malting plant. Trans Energy Systems has analyzed several systems of utilizing the geothermal resource at the Great Western barley malting facility. These systems included: direct use of geothermal water; geothermal energy heating process water through an intermediary heat exchanger; coal or gas boosted geothermal systems; and heat pump boosted geothermal system. The analysis examined the steps that are required to process the grain.

    The possibility of using [ 18 F] FDG PET for assessment of tumor extension in primary gastric non-Hodgkin's lymphoma (NHL) was studied in 8 patients (6 high-grade and 2 low-grade, one of the MALT type) and in a control group of 7 patients (5 patients with NHL without clinical signs of gastric involvement, 1 patient with NHL and benign gastric ulcer and 1 patient with adenocarcinoma of the stomach). All patients with gastric NHL and the two with benign gastric ulcer and adenocarcinoma, respectively, underwent endoscopy including multiple biopsies for histopathological diagnosis. All patients with high-grade and one of the two with low-grade NHL and the patient with adenocarcinoma displayed high gastric uptake of [ 18 F] FDG corresponding to the pathological findings at endoscopy and/or CT. No pathological tracer uptake was seen in the patient with low-grade gastric NHL of the MALT type. In 6/8 patients with gastric NHL, [ 18 F] FDG PET demonstrated larger tumor extension in the stomach than was found at endoscopy, and there was high tracer uptake in the stomach in two patients who were evaluated as normal on CT. [ 18 F] FDG PET correctly excluded gastric NHL in the patient with a benign gastric ulcer and in the patients with NHL without clinical signs of gastric involvement. Although the experience is as yet limited, [ 18 F] FDG PET affords a novel possibility for evaluation of gastric NHL and would seem valuable as a complement to endoscopy and CT in selected patients, where the technique can yield additional information decisive for the choice of therapy.

    Purpose: Mucosa-associated lymphoid tissue (MALT) lymphoma is a distinct disease with specific clinical and pathologic features that may affect diverse organs. We analyzed our recent experience with Stage I/II MALT lymphoma presenting in the stomach and other organs to assess the outcome following involved field radiation therapy (RT). Patients and Methods: Seventy patients with Stage IE (62) and IIE (8) disease were treated between 1989 and 1998. Patients with transformed MALT were excluded. The median age was 62 years (range, 24-83 years), M:F ratio 1:2.2. Presenting sites included stomach, 15; orbital adnexa, 19; salivary glands, 15; thyroid, 8; lung, 5; upper airways, 3 (nasopharynx, 2; larynx, 1); urinary bladder, 3; breast, 1; and rectum, 1. Staging included site-specific imaging, CT abdomen in 66 patients (94%) and bone marrow biopsy in 54 (77%). Sixty-two patients received radiation therapy: 52 received RT alone, 7 received chemotherapy and RT, and 3 received antibiotics followed by RT. Median RT dose was 30 Gy (range, 17.5-35 Gy). Most frequently used RT prescriptions were 25 Gy (26 patients--18 orbit, 6 stomach, and 2 salivary glands), 30 Gy (23 patients), and 35 Gy (8 patients). Five patients had complete surgical excision of lymphoma and no other treatment (stomach 1, salivary 2, lung 2), whereas 2 patients with gastric lymphoma received antibiotics only. One patient refused treatment and was excluded from the analysis of treatment outcome, leaving 69 patients with a median follow-up of 4.2 years (range, 0.3-11.4 years). Results: A complete response was achieved in 66/69 patients, and 3 patients had partial response (2 lung, 1 orbit). The 5-year disease-free survival (DFS) was 76%, and the overall survival was 96%. No relapses were observed in patients with stomach and thyroid lymphoma. The 5-year DFS for these patients was 93%, in contrast to 69% for patients presenting in other sites (p 0.006). Among the 5 patients treated with surgery only, 2

    Mercury is a metal of particular concern due to its toxicity even at relatively low concentrations. The maximum permissible level for mercury in drinking water set by the European Union is 0.001 mg/L. Mercury is released into the environment via four principal pathways: (1) natural processes; i.e. a volcanic eruption, (2) incidental to some other activity; i.e. coal burning power plants, (3) accidentally during the manufacture, breakage or disposal of products that have mercury put into them deliberately, and (4) direct use in industrial settings. The present study focuses on the removal of mercury (II) from aqueous solutions via sorption onto Malt Spent Rootlets (MSR). Batch experiments were conducted employing MSR with size ranging from 0.18 to 1 mm. The effects of pH, mercury concentration, contact time, and solid to liquid ratio on mercury sorption onto MSR were investigated. The highest mercury removal from the aqueous phase, of 41%, was observed at pH of 5.

  5. Endoproteolytic activity assay in malting barley

    Full Text Available Hydrolysis of barley proteins into peptides and amino acids is one of the most important processes during barley germination.The degradation of the endosperm stored proteins facilitates water and enzyme movements, enhances modification, liberates starch granules and increases soluble amino nitrogen. Protease activity is the result of the activities of a mixture of exo- and endo-proteases. The barley proteins are initially solubilized by endo-proteases and the further by exo-proteases. Four classes of endo-proteases have been described: serine-proteases, cysteine-proteases, aspartic-proteases and metallo-proteases. The objective of this work was to develop a rapid and colorimetric enzymatic assay to determine the endo-proteolytic activity of the four endo-protease classes using two different substrates: azo-gelatin and azo-casein. Optimum conditions for the assays such as: pH,reaction time and temperature and absorbance scale were determined. Azo-gelatin presented several difficulties in standardizing an “in solution” assay. On the other hand, azo-casein allowed standardization of the assay for the four enzyme classes to produce consistent results. The endo-proteoteolytic method developed was applied to determine the endo-protease activity in barley, malt and wort.

    Schechter, Naomi R.; Yahalom, Joachim

    2000-01-01

    Purpose: Low-grade mucosa-associated lymphoid tissue (MALT) lymphoma of the stomach (MLS) is often associated with the presence of Helicobacter pylori (H. pylori) bacteria. Eradication of the infection with antibiotic therapy may result in regression of the lymphoma. But when antibiotic treatment fails to reverse the malignant process or if H. pylori is absent, other treatment options should be considered. Because MLS is often confined to the stomach and regional lymph nodes, it is potentially curable with local therapy. Endoscopy and improved imaging, with endoscopic ultrasound (EUS) and computerized tomography (CT), have reduced the prior dependence on surgery for diagnosis and staging of gastric lymphomas. Methods and Results: This review details the advances in the diagnosis, classification, and imaging of MLS. We also describe the experience that supports the use of radiation therapy as the preferred treatment of MLS in patients who have not responded to antibiotic therapy or have not had evidence for H. pylori infection. Conclusions: Radiation therapy for MLS is not only effective and safe, but offers the significant advantage of low morbidity and gastric function preservation

  8. Comparison of Rheological Properties of Hopped Wort and Malt Wort

    Full Text Available The aim of this work is determination rheological properties of hopped wort and malt wort and their comparison. In the paper following rheological properties has been described: the dependence of viscosity on a temperature of a sample and hysteresis loop test. The time dependence test was performed for a confirmation thixotropic behaviour. Based on measured values Arrhenius mathematical model has been applied. The activation energy was determined by using of this model. Tests have been carried out in the temperature range from 5 °C to 40 °C. Rheological tests proved that malt wort behaves as Newtonian fluid in all temperatures and hopped wort behaves as non-Newtonian fluid at low temperatures. Thixotropic behaviour is caused by the content of the rests of hops heads or malt scraps.

    We report four cases of lingual tonsillar MALT (mucosal associated lymphoid tissue) lymphoma. The cases consisted of a 68-year-old woman, a 60-year-old woman, a 55-year-old woman, and a 75-year-old man. The clinical stages of these cases were IIA, IA, IV (invasion to bone marrow) and IA, respectively. As some types of lingual tonsillar MALT lymphomas show hypertrophy of the lymphoid tissue but not a mass, it is not easy to make a diagnosis of MALT lymphoma only by fiberscopic findings. Furthermore, the small size of biopsy specimens or tissue damaged by forceps can show a false negative consult. Repeat biopsies are sometimes required for a definitive diagnosis. It is important to take large biopsy specimens with little damage, and to discuss well with pathologists. (author)

    Gibson, Nigel B.; Costigan, Gavin T.; Swannell, Richard P. J.; Woodfield, Michael J.

    Estimates have been made of the amounts of volatile organic compounds (VOCs) released during different stages of beer manufacture. The estimates are based on recent measurements and plant specification data supplied by manufacturers. Data were obtained for three main manufacturing processes (malting, wort processing and fermentation) for three commercial beer types. Some data on the speciation of emitted compounds have been obtained. Based on these measurements, an estimate of the total unabated VOC emission. from the U.K. brewing industry was calculated as 3.5 kta -1, over 95% of which was generated during barley malting. This value does not include any correction for air pollution control.

    Rose, Neil L; Yang, Handong; Turner, Simon D

    2016-02-01

    Mercury (Hg) concentrations were measured in 26 Scottish single malt whiskies, and all found to be very low (mercury emissions and deposition over the last 200 years affecting concentrations in local waters used in whisky production. As UK atmospheric emissions of mercury have declined by 90 % since the 1970s, we suggest that whisky being produced today should have even lower Hg concentrations when consumed in 10- to 15-years time. This reduction may be compromised by the remobilisation of contaminants stored in catchment soils being transferred to source waters, but is very unlikely to raise the negligible health risk due to Hg from Scottish single malt whisky consumption.

    Full Text Available The possibility of application of malt extract as a source of carbohydrate in a medium for tea fungus was investigated. The beverage obtained on such medium was compared with that prepared in a traditional way with sucrose medium. The presence of easily adoptable sugars, glucose and fructose, as dominant in malt medium results in a very effective fermentation, which gives much more sour beverage for the same time and makes it possible to reduce the fermentation period. The obtained beverage has satisfactory sensorial characteristics.

    The use of 18F-fluoro-deoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in primary gastric lymphoma (PGL) is challenging due to physiologic FDG activity in the stomach and variability in the degree of uptake in various histologic subtypes. This study assesses FDG avidity and PET/CT patterns in newly diagnosed PGL. Sixty-two PET/CT studies of newly diagnosed PGL were reviewed (24 low-grade mucosa-associated lymphoid tissue [MALT], 38 aggressive non-Hodgkin's lymphoma [AGNHL]). FDG avidity, patterns (focal/diffuse), and intensity (visually vs. the liver and SUVmax) were assessed and compared to 27 controls. Gastric CT abnormalities and extragastric sites were recorded. Gastric FDG uptake was found in 55/62 (89%) PGL (71% MALT vs. 100% AGNHL, p < 0.001) and 63% controls. A diffuse pattern was found in 60% PGL (76% MALT vs. 53% AGNHL, p = NS) and 47% controls. FDG uptake higher than liver was found in 82% PGL (58% MALT vs. 97% AGNHL, p < 0.05) and 63% controls. SUVmax in FDG-avid PGLs was 15.3 ± 11.7 (5.4 ± 2.9 MALT vs. 19.7 ± 11.5 AGNHL, p < 0.001) and 4.6 ± 1.4 in controls. CT abnormalities were found in 79% PGL (thickening, n = 49; ulcerations, n = 22). Extra-gastric FDG-avid sites were seen in none of MALT, but 61% of AGNHL (nodal, n = 18; nodal and extranodal, n 5). FDG avidity was present in 89% of PGLs, including all patients with AGNHL but only 71% of MALT. FDG uptake can be differentiated, in particular in AGNHL-PGL, from physiologic tracer activity by intensity but not by pattern. Extragastric foci on PET and structural CT abnormalities are additional parameters that can improve PET/CT assessment of PGL. Defining FDG avidity and PET/CT patterns in AGNHL and a subgroup of MALT-PGL before treatment may be important for further monitoring therapy response. (orig.)

    AIM:To assess the significance of chromosome translocation t(11;18)(q21;q21),B-cell lymphoma 10 (BCL-10)protein and Helicobacter pylori (H.pylori) infection in gastric mucosa-associated lymphoid tissue (MALT) lymphoma in Colombia.METHODS:Fifty cases of gastric MALT lymphoma and their respective post-treatment follow-up biopsies were examined to assess the presence of the translocation t(11;18)(q21;q21) as identified by fluorescence in situ hybridization; to detect protein expression patterns of BCL10 using immunohistochemistry; and for evaluation of tumor histology to determine the correlation of these factors and resistance to H.pylori eradication.RESULTS:Infection with H.pylori was confirmed in all cases of gastric MALT lymphoma in association with chronic gastritis.Bacterial eradication led to tumor regression in 66% of cases.The translocation t(11;18)(q21;q21) was not present in any of these cases,nor was there evidence of tumor transformation to diffuse large B-cell lymphoma.Thirty-four percent of the patients showed resistance to tumor regression,and within this group,7 cases,representing 14% of all those analyzed,were considered to be t(11;18)(q21;q21)-positive gastric MALT lymphomas.Protein expression of BCL10 in the nucleus was associated with the presence of translocation and treatment resistance.Cases that were considered unresponsive to therapy were histologically characterized by the presence of homogeneous tumor cells and a lack of plasmacytic differentiation.Responder cases exhibited higher cellular heterogeneity and a greater frequency of plasma cells.CONCLUSION:Both t(11;18)(q21;q21)-positive MALT lymphoma cases and those with nuclear BCL10 expression are considered resistant to H,pylori eradication.It is suggested that chronic antigenic stimulation is not a dominant event in resistant cases.

    Full Text Available In this work the α and β-amylase enzymes were obtained from maize (Zea mays malt and were biochemistry characterized. A germination study to obtain the maize malt with good amylase activity was made. The maize seeds were germinated in laboratory and the enzymatic activity was measured daily. Activity dependence to germination time were fitted to an exponential model (A=A0eµt, which showed that the behaviour of enzymatic activity in the germination process was similar to the growth of the microorganism. Its model could be applied to describe the mechanism of α-amylase production for each maize varieties and others cereals. Maize malt characterization showed that α and β-amylase had optimal pH between 4-6.5, optimal temperature 50 and 90ºC, and molecular weight of 67.4 and 47.5kDa, respectively. This work contributed with the advances in biotechnology generating of conditions for application of a new and of low price amylases source.Neste trabalho as enzimas α e β-amilases foram obtidas de malte de milho e depois foram caracterizadas bioquimicamente. Um estudo da germinação foi feito para obtenção do malte com boa atividade amilásica. A germinação ocorreu em escala laboratorial e a atividade enzimática foi medida diariamente. Um modelo exponencial do tipo A=A0eµt foi ajustado a dependência do tempo de germinação com a atividade, mostrando que o comportamento da atividade enzimática no processo de germinação é semelhante ao crescimento de microorganismos. Este modelo pode ser aplicado para descrever o mecanismo de produção da α-amilase para cada variedade de milho e de outros cereais. A caracterização do malte de milho mostrou que as α e β-amilase têm pH ótimo entre 4,0-6,5, temperatura ótima de 50 e 90ºC, e massa molar de 67,4 e 47,5 kDa, respectivamente. Este trabalho contribuiu com os avanços da biotecnologia gerando condições de emprego de uma nova e barata fonte de amilases.

    Malted grains are extensively used in weaning and geriatric foods. Malting generally improves the nutrient content and digestibility of foods. The present investigation examined the influence of malting of finger millet, wheat, and barley on the bioaccessibility of iron, zinc, calcium, copper, and manganese. Malting increased the bioaccessibility of iron by >3-fold from the two varieties of finger millet and by >2-fold from wheat, whereas such a beneficial influence was not seen in barley. The bioaccessibility of zinc from wheat and barley increased to an extent of 234 and 100%, respectively, as a result of malting. However, malting reduced the bioaccessibility of zinc from finger millet. Malting marginally increased the bioaccessibility of calcium from white finger millet and wheat. Whereas malting did not exert any influence on bioaccessibility of copper from finger millet and wheat, it significantly decreased (75%) the same from barley. Malting did increase the bioaccessibility of manganese from brown finger millet (17%) and wheat (42%). Thus, malting could be an appropriate food-based strategy to derive iron and other minerals maximally from food grains.

    The possibility of using [{sup 18}F] FDG PET for assessment of tumor extension in primary gastric non-Hodgkin`s lymphoma (NHL) was studied in 8 patients (6 high-grade and 2 low-grade, one of the MALT type) and in a control group of 7 patients (5 patients with NHL without clinical signs of gastric involvement, 1 patient with NHL and benign gastric ulcer and 1 patient with adenocarcinoma of the stomach). All patients with gastric NHL and the two with benign gastric ulcer and adenocarcinoma, respectively, underwent endoscopy including multiple biopsies for histopathological diagnosis. All patients with high-grade and one of the two with low-grade NHL and the patient with adenocarcinoma displayed high gastric uptake of [{sup 18}F] FDG corresponding to the pathological findings at endoscopy and/or CT. No pathological tracer uptake was seen in the patient with low-grade gastric NHL of the MALT type. In 6/8 patients with gastric NHL, [{sup 18}F] FDG PET demonstrated larger tumor extension in the stomach than was found at endoscopy, and there was high tracer uptake in the stomach in two patients who were evaluated as normal on CT. [{sup 18}F] FDG PET correctly excluded gastric NHL in the patient with a benign gastric ulcer and in the patients with NHL without clinical signs of gastric involvement. Although the experience is as yet limited, [{sup 18}F] FDG PET affords a novel possibility for evaluation of gastric NHL and would seem valuable as a complement to endoscopy and CT in selected patients, where the technique can yield additional information decisive for the choice of therapy.

    Full Text Available Emmer wheat (EW, Triticum dicoccum grows under adverse climatic and soil conditions in the hilly areas of Italy and other temperate regions. So far, EW has been used for pasta or bakery products. The malt obtained from EW was used to produce a light beer, a double malt beer, and beers with 50% (B50 and 30% (B30 EW malt combined with barley malt. These top-fermented beers showed a sweet, fruity, citrus character. The different sensory impact and chemical composition (betaglucans and flavanoids of the beers was related to the germinative energy of EW and the different proportions of malted EW and barley malt. The light beer combines the moderate alcohol (3% vol. with a good intake of natural antioxidants (total phenolic content, TPC, 85 mg l−1, whereas B50 showed a high TPC (109 mg l−1 and the highest beta-glucan content (27 mg l−1.

    Gastric pseudolymphoma is an uncommon benign lesion which poses a difficult problem in diagnosis and management. Lymphoid hyperplasia of the stomach, however, may occasionally precede true gastric lymphoma. Endoscopic, radiologic and pathological findings are not generally helpful in establishing the diagnosis preoperatively. Benign gastric lymphoid hyperplasia could be mistaken radiologically for ulcerated gastric carcinoma and pathologically for malignant lymphoma. Recognition of this condition is important to prevent unnecessary treatment by surgery or radiotherapy. About 140 case reports have been published to date. This paper describes the cases of two further patients. (orig.) [de

    2007-01-01

    Gastric cancer is still a major health problem and a leading cause of cancer mortality despite a worldwide decline in incidence. Primarily due to early detection of the disease, the results of treatment for gastric cancer have improved in Japan, Korea and several specialized Western centres. Surgery offers excellent long-term survival results for early gastric cancer (EGC). In the Western world, however more than 80 % of patients at diagnosis have an advanced gastric cancer with a poor prognosis. The aim of surgery is the complete removal of the tumour (UICC R0-resection), which is known to be the only proven, effective treatment modality and the most important treatmentrelated prognostic factor. The prognosis after surgical treatment of gastric cancer remains poor. Neoadjuvant chemotherapy is a rising option in locally advanced gastric cancer. Adjuvant chemoradiation has been shown to be beneficial in gastric cancer patients who have undergone suboptimal surgical resection. The benefits of adjuvant chemotherapy alone seem to be very small, Untreated metastatic gastric cancer is associated with a median survival of only 3 - 4 months, but this can be increased to 8 - 10 months, associated with improved quality of life, with combination chemotherapy. Currently, no standard combination chemotherapy regimen exists, although regimens utilizing both cisplatin and 5-fluorouracil, such as epirubicin/cisplatin/fluorouracil (ECF) or docetaxel/cisplatin/fluorouracil (DCF) are amongst the most active. Newer chemotherapeutic agents, including irinotecan, oxaliplatin and taxanes, show promising activity, and are currently being tested with biologics in clinical trials. (author)

    A 65-year old patient, with no medical history, was admitted for lower gastrointestinal bleeding. On clinical examination the patient seemed to be in good health. However the examination was completed with a rectosigmoidoscopy revealing the presence of mucosal erosions, ulcerations, multiple papulae. The histopathological examination raised the suspicion of a colonic lymphoma. Gastric biopsies suggested a gastric MALT type lymphoma associated to the colonic lymphoma, but the immunohistochemical profile corresponded to a mantle cell lymphoma. In spite of the general poor prognosis of mantle cell lymphoma, our patient had a good clinical and endoscopic response to the standard cyclophosphamide, vincristine, prednisone (CVP) therapy. The cases of gastric and colonic mantle lymphoma are rare, the response to therapy is poor; fortunately, our patient had a complete resolution after completion of the six cycles of chemotherapy.

    MALT1 is involved in the activation of immune responses, as well as in the proliferation and survival of certain cancer cells. MALT1 acts as a scaffold protein for NF-κB signaling and a cysteine protease that cleaves substrates, further promoting the expression of immunoregulatory genes. Deregulated MALT1 activity has been associated with autoimmunity and cancer, implicating MALT1 as a new therapeutic target. Although MALT1 deficiency has been shown to protect against experimental autoimmune encephalomyelitis, nothing is known about the impact of MALT1 on virus infection in the central nervous system. Here, we studied infection with an attenuated rabies virus, Evelyn-Rotnycki-Abelseth (ERA) virus, and observed increased susceptibility with ERA virus in MALT1 -/- mice. Indeed, after intranasal infection with ERA virus, wild-type mice developed mild transient clinical signs with recovery at 35 days postinoculation (dpi). Interestingly, MALT1 -/- mice developed severe disease requiring euthanasia at around 17 dpi. A decreased induction of inflammatory gene expression and cell infiltration and activation was observed in MALT1 -/- mice at 10 dpi compared to MALT1 +/+ infected mice. At 17 dpi, however, the level of inflammatory cell activation was comparable to that observed in MALT1 +/+ mice. Moreover, MALT1 -/- mice failed to produce virus-neutralizing antibodies. Similar results were obtained with specific inactivation of MALT1 in T cells. Finally, treatment of wild-type mice with mepazine, a MALT1 protease inhibitor, also led to mortality upon ERA virus infection. These data emphasize the importance of early inflammation and activation of T cells through MALT1 for controlling the virulence of an attenuated rabies virus in the brain. IMPORTANCE Rabies virus is a neurotropic virus which can infect any mammal. Annually, 59,000 people die from rabies. Effective therapy is lacking and hampered by gaps in the understanding of virus pathogenicity. MALT1 is an intracellular

    Industrial malt in Kenya for commercial beer production is made exclusively from barley. This study explored the potential of producing suitable malt from some sorghum and finger millet grain varieties grown in Kenya. Malting characteristics of two sorghum grain varieties, KARI Mtama-1 and local Red variety, and that of finger millet was done and compared to that of barley. Among the grain characteristics determined before malting were water sensitivity, polyphenol (tannin) content and total protein. The grain was malted by striping in water for 48 h, followed by germination for four days at 25 degrees celcious, then kilned at 50 degrees celcious for 24 h. The malting characteristics determined included total soluble N, free amino N, wort pH and fermentable sugars. The local red sorghum and millet had high polyphenol content while KARI Mtama-1 and barley had low levels. KARI Mtama-1 had positive water sensitivity while barley had negative sensitivity. Finger millet and local red sorghum were water insensitive. Free amino N was 113, 125, 144, and 154mg 100g - 1 malt for millet, barley, local Red and KARI Mtama-1, respectively. Total fermentation sugars were 307, 477, 610 and 178 mg 1 - 1 for finger millet, local red, barley and KARI Mtama 1 , respectively. The results showed that that the proteolytic and amyloytic characteristics of the KARI Mtama-1 malt are largely similar to those of barley. Hence the KARI Mtama-1 malt are largely similar to those of barley. Hence the KARI Mtama-1 has good potential fro conventional lager beer production. Malts of local Red sorghum grain and millet may be more suitable for industrial production of opaque/cloudy beer

    Full Text Available Versatile microbiota are inevitably naturally present on cereals. Fungi, yeasts and bacteria and their metabolites all contribute to the quality and safety of the final products derived from most common beer cereals—barley and wheat. The microorganisms that are most often associated with the safety and quality of cereals for beer production belong to the Fusarium spp. They greatly influence yields from the field, and can modify and diminish economic success for farmers. However, the real problem is their harmful metabolites—mycotoxins—that affect the health of humans and animals. In the era of emerging analytical methodologies, the spectrum of known toxins originating from microorganisms that can pose a threat to humans has grown tremendously. Therefore, it is necessary to monitor microflora throughout the productive “barley to beer” chain and to act suppressive on the proliferation of unwanted microorganisms, before and during malting, preventing the occurrence of mycotoxins in final products and by-products. Multi-mycotoxin analyses are very advanced and useful tools for the assessment of product safety, and legislation should follow up and make some important changes to regulate as yet unregulated, but highly occurring, microbial toxins in malt and beer.

    Energy requirements and exergy inefficiencies for processing of malt drink were estimated for a Nigerian brewery. The process was divided into twenty-one basic unit operations and grouped into four main group operations: silo house, brew house, filter room and packaging house. The energy intensity for processing a batch of 9.8 tonnes brew grains to 562 hl of malt drink was estimated as 261.63 MJ/hl consisting of electrical (41.01%), thermal (58.81%) and manual (0.19%) of the total energy. The most energy intensive group operation was the Packaging House operation, followed by the Brew House operation with energy intensities of 223.19 and 35.94 MJ/hl, respectively. The exergy analysis revealed that the packaging house operation was responsible for most of the inefficiency (92.16%) followed by brew house operation (7.17%) and the silo house and filter room operations with less than 1% of the total exergy lost. The most exergy loss took place in the pasteurizer, which accounted for 59.75% of the overall system inefficiency. Modification in the pasteurizer and use of spent grains as alternate source of energy in the steam boiler were recommended to improve the energy efficiency of the system.

    1985-01-01

    Factors influencing gastric emptying were studied by measuring gastric emptying time (GET) with RI experimentally and clinically. The restlts are as follows: 1. The parasympathetic blockers suppressed gastric emptying but the parasympathetic stimulater did not accelerate it. 2. Posture of the subject in measurement influenced gastric emptying and GET was reduced in order of prone, sitting and supine positions. 3. In cases of gastric and duodenal ulcer, there were differences of GET between pre-operation and post-operation depending on the methods of operation. 4. The GET was measured to investigate the gastric emptying of liquid and solid food by double RI tracer method, using 99m Tc-DTPA and 111 In-DTPA which were measured separately. The GET of liquid food was faster than that of solid food and was influenced by the stickiness of coexistent solid food. On the other hand, the GET of solid food tended to be faster with increasing stickiness. (author)

    1985-01-01

    70 cases of gastric mucosal erosions were diagnosed by double contrast upper gastrointestinal examinations and endoscopic findings. Analyzing the radiologic findings of these 70 cases of gastric mucosal erosions, the following results were obtained. 1. Among the total 70 cases, 65 cases were typical varioliform erosions showing central depressions and surrounding mucosal elevations. Remaining 5 cases were erosions of acute phase having multiple irregular depressions without surrounding elevations. 2. The gastric antrum was involved alone or in part in all cases. Duodenal bulb was involved with gastric antrum in 4 cases. 3. The majority of the cases had multiple erosions. There were only 2 cases of single erosion. 4. In 65 cases of varioliform erosions; 1) The diameter of the surrounding elevations varied from 3 to 20 mm with the majority (47 cases) between 6 and 10 mm. 2) In general, the surrounding elevations with sharp margin on double contrast films were also clearly demonstrated on compression films but those with faint margin were not. 3) The size of the central barium collections varied from pinpoint to 10 mm with the majority under 5 mm.

    The article deals with the research of using the sludge from malting industry wastewater’s biological treatment and the calcium carbonate slurry as organo-mineral fertilizing additives. The sludge, generated as a result of industrial wastewater biological treatment, is subject to dumping at solid domestic waste landfills, which has a negative impact on the environment, though its properties and composition allow using it as an organic fertilizer. The physical and chemical properties of both wastes have been studied; the recommendations concerning the optimum composition of soil mix, containing the above-mentioned components, have been provided. The phytotoxic effect on the germination capacity and sprouts of cress (Lepidium sativum), barley (Hordéum vulgáre) and oats (Avena sativa) in soil mixes has been determined. The heavy metals and arsenic contents in the sludge does not exceed the allowable level; it is also free of pathogenic flora and helminthes.

    Gastric emptying (GE) of nutriments is a major function of the stomach. GE disorders are observed after gastric surgery and with various diseases, either of a strictly gastroenterologic kind or interesting other specialities (especially diabetes mellitus). Scintigraphy, which has allowed a better knowledge of GE physiological and pathological mechanisms, has now become the reference method for studying the emptying of solids and liquids. In a near future, it could well have two major applications: a diagnostic approach of functional digestive disorders and an assessment of the various effects of pharmacological drugs with digestive affinity [fr

    The current study aimed to summarize the clinical manifestations and identify the epigenetic mechanisms of gastric mucosa associated lymphoid tissue (MALT) lymphoma, as well as evaluate the long-term effects of Helicobacter pylori ( H. pylori ) eradication. A total of 122 patients with marginal zone B-cell lymphoma of primary gastric MALT lymphoma were enrolled in the present study. The clinical manifestations of gastric MALT lymphoma, including symptoms, H. pylori state and endoscopic type, were summarized. The response to therapy was evaluated in patients that underwent H. pylori eradication. Survival analysis was estimated using the Kaplan-Meier method. The expression of microRNA-383 (miR-383) in tumor tissues and cell lines was determined using reverse transcription quantitative polymerase chain reaction. Furthermore, bioinformatic analyses, luciferase reporter assays. and western blot analysis identified zinc finger E-box binding homeobox 2 (ZEB2) as a direct target gene of miR-383. An MTT assay was used to examine the function of miR-383 and ZEB2 in MALT lymphoma. The clinical symptoms of patients with gastric MALT lymphoma were non-specific and included epigastric pain, abdominal discomfort and bleeding. The majority of endoscopic types were classified as ulcer, erosion and mucosa edema. The H. pylori infection rate was 79.5% (97/122) and a total of 47 patients underwent eradication therapy. Lymphoma remission was achieved in 93.6% (44/47) of patients and complete remission (CR) was achieved in 74.4% (35/47). The median follow-up time was 38 months (range, 10-132 months) and the median time taken to achieve CR was 4 months (range, 3-7 months). The estimated 3-year survival rate was 90.3% and the 5-year survival rate was 76.2%. Therefore, it was determined that patients with stage I or II gastric MALT lymphoma are able to undergo H. pylori eradication as a first-line treatment and that the survival rate of patients undergoing this treatment is high

    Full Text Available Gastric colonization with Helicobacter pylori induces diverse human pathological conditions, including superficial gastritis, peptic ulcer disease, mucosa-associated lymphoid tissue (MALT lymphoma, and gastric adenocarcinoma and its precursors. The treatment of these conditions often relies on the eradication of H. pylori, an intervention that is increasingly difficult to achieve and that does not prevent disease progression in some contexts. There is, therefore, a pressing need to develop new experimental models of H. pylori-associated gastric pathology to support novel drug development in this field. Here, we review the current status of in vivo and ex vivo models of gastric H. pylori colonization, and of Helicobacter-induced gastric pathology, focusing on models of gastric pathology induced by H. pylori, Helicobacter felis and Helicobacter suis in rodents and large animals. We also discuss the more recent development of gastric organoid cultures from murine and human gastric tissue, as well as from human pluripotent stem cells, and the outcomes of H. pylori infection in these systems.

    2017-01-01

    Full Text Available The article deals with production of various malts intended for manufacture of special types of beer. The malts were used to brew samples of beer with alcoholic strength ranging between 8 - 12% EPM. The above range of original wort content was chosen due to its suitability for sensory evaluation and properties; in stronger types of beer, (more than 12% EPM, nature of the beverage can be drown by mashy flavour. In the experimental samples, the actual residual extract oscillated between 4.0 - 6.5%. The content of ethanol corresponded to the degree of fermentation and thereby also to the residual actual extract in balance equilibrium specifying that higher residual extract corresponds to lower content of alcohol by volume. It ranged between 2.5 - 5.0%. The sample 1 contained the highest amount of ethanol by mass (3.9% and the sample 13 showed the lowest one (1.9%; alike trend of ethanol content by volume was revealed (5 and 2.44%, respectively. The highest content of actual and apparent extract was found in the sample 2 (6.6 and 5.2%, respectively; the sample 13 showed the lowest levels (4.0 and 3.1%, respectively. The original wort extract content averaged 9.9% in most of the samples; the sample 1 showed distinctly higher value (12.6% and, on the contrary, the sample 13 demonstrated the lowest one (7.4%. The highest relative density was revealed in the sample 2 (1.02% and the lowest one in the sample 13 (1.01%. Considering differences in osmotic pressure, the sample 1 exhibited the highest value (1045 mOs and the sample 13 the lowest one (551 mOs. The highest level of fermentation was found in the sample 19 (61.7%, the lowest one was proved in the sample 19 (44.0%. Sensory analysis corresponded to originality and characteristics of each sample. The sample of beer made from spring barley was evaluated to be the best one.

  5. Competitive intransitivity promotes species coexistence.

    Using a spatially explicit cellular automaton model with local competition, we investigate the potential for varied levels of competitive intransitivity (i.e., nonhierarchical competition) to promote species coexistence. As predicted, on average, increased levels of intransitivity result in more sustained coexistence within simulated communities, although the outcome of competition also becomes increasingly unpredictable. Interestingly, even a moderate degree of intransitivity within a community can promote coexistence, in terms of both the length of time until the first competitive exclusion and the number of species remaining in the community after 500 simulated generations. These results suggest that modest levels of intransitivity in nature, such as those that are thought to be characteristic of plant communities, can contribute to coexistence and, therefore, community-scale biodiversity. We explore a potential connection between competitive intransitivity and neutral theory, whereby competitive intransitivity may represent an important mechanism for "ecological equivalence."

    Barley is the cornerstone of the malting and brewing industry. It is known that 250 quantitative trait loci (QTLs) of the grain are associated with 19 malting-quality phenotypes. However, only a few of the contributing genetic components have been identified. One of these, on chromosome 4H, contains a major malting QTL, QTL2, located near the telomeric region that accounts, respectively, for 28.9% and 37.6% of the variation in the β-glucan and extract fractions of malt. In the current study, we dissected the QTL2 region using an expression- and microsynteny-based approach. From a set of 22 expressed sequence tags expressed in seeds at the malting stage, we identified a candidate gene, TLP8 ( thaumatin-like protein 8 ), which was differentially expressed and influenced malting quality. Transcript abundance and protein profiles of TLP8 were studied in different malt and feed varieties using quantitative PCR, immunoblotting, and enzyme-linked immunosorbent assay (ELISA). The experiments demonstrated that TLP8 binds to insoluble (1, 3, 1, 4)-β-D glucan in grain extracts, thereby facilitating the removal of this undesirable polysaccharide during malting. Further, the binding of TLP8 to β-glucan was dependent on redox. These findings represent a stride forward in our understanding of the malting process and provide a foundation for future improvements in the final beer-making process.

    Full Text Available Beer manufacturing is one of the most ancient procedures of food manufacturing. The four (in many cases much more ingredients, the great numbers of technological steps and variations of technological parameters (temperature, time, pressure etc. have a major influence on both type and quality of the final product. As a result of this, studying beer brewing may offer a great deal of possibilities for numerous researches, scientific examinations, and can provide useful informations for the manufacturing companies as well. At the „Slovak University of Agriculture in Nitra" we examined an entire beer brewing process in October 2013, utilising the Ahlborn sensors, which were integrated in the instruments. Simultaneously, in Gödöllő at the Szent István University, we analysed the effect of malt milling on extract yield and the filterability of wort. We used the brewing parameters (temperature, time, volume ratios, which were experienced in the microbrewery and published in professional literature. Our results verify the conclusions drawn in the professional literature, however they point out the importance of grinding. Results performed on the yields with different grain-constitution might directly be utilised for the specialists of recently in Slovakia and Hungary spreading small-scale, handicraft, and homemade beer brewing.

    Using molecular-line data from the Millimetre Astronomy Legacy Team 90 GHz Survey (MALT90), we have estimated kinematic distances to 1905 molecular clumps identified in the ATLASGAL 870 μ m continuum survey over the longitude range 295° <  l  < 350°. The clump velocities were determined using a flux-weighted average of the velocities obtained from Gaussian fits to the HCO{sup +}, HNC, and N{sub 2}H{sup +} (1–0) transitions. The near/far kinematic distance ambiguity was addressed by searching for the presence or absence of absorption or self-absorption features in 21 cm atomic hydrogen spectra from the Southern Galactic Plane Survey. Our algorithm provides an estimation of the reliability of the ambiguity resolution. The Galactic distribution of the clumps indicates positions where the clumps are bunched together, and these locations probably trace the locations of spiral arms. Several clumps fall at the predicted location of the far side of the Scutum–Centaurus arm. Moreover, a number of clumps with positive radial velocities are unambiguously located on the far side of the Milky Way at galactocentric radii beyond the solar circle. The measurement of these kinematic distances, in combination with continuum or molecular-line data, now enables the determination of fundamental parameters such as mass, size, and luminosity for each clump.

    A steam heat pump was installed in the Auchroisk malt whiskey distillery of International Distillers and Vintners Ltd. as a result of a four year research and development program. Distillation accounts for 67 million CJ of energy use per annum in the UK, much of which is provided by steam and most of which is ejected into the environment by cooling towers. A closed cycle heat pump with water/steam as the working fluid which uses heat exchangers designed to give low approach temperatures can have a high coefficient of performance (COP) which would ensure a large energy saving and a good economic return. The installation has shown that a heat pump can produce large energy savings in distillation. In this instance, the heat pump has achieved over 90 % of its design performance and operated continuously. The use of steam as a working fluid was shown to have advantages over other fluids, mostly in the area of integration with the existing steam services. 3 refs., 9 figs.

The pain was intermittent, located at the epigastric region, non-radiating, fluctuating intensity up to 8/10, and had worsened over the past month. She did not have fever, nausea, vomiting, diarrhea, constipation, or blood in her stool. The patient also endorsed hair loss over the same time period and noted that her previously long hair was now short and thin. On exam, patient was noted to have shoulder-length hair, a soft, non-distended abdomen with mild tenderness to the epigastric region, and a 5cm hard mass palpated at the epigastrium. Significant findings: In the abdominal radiograph, a nonspecific and non-obstructive bowel gas pattern with no air-fluid level was noted, however the stomach was distended with soft tissue. The CT abdomen/pelvis revealed a distended stomach with undigested heterogeneous contents (presumed bezoar. Discussion: A bezoar is a mass of incompletely digested material typically originating in the stomach and consisting of vegetable fibers, hair, or drugs.1 Bezoars develop after ingested foreign material accumulates in the gastrointestinal tract due to indigestibility, gastric outlet obstruction, or intestinal stasis. Trichobezoars are comprised of hair and classically form in young females with an underlying psychiatric disorder resulting in the urge to pull one’s hair out (trichotillomania and swallow it (trichophagia.2,3 Gastric bezoars are rare with an approximate incidence of 0.3 percent of patients undergoing upper endoscopy.4 Patients tend to remain asymptomatic for long periods, but may develop abdominal pain, nausea/vomiting, early satiety, anorexia, and weight loss.5 Complications may include gastrointestinal ulcerations, perforations, intussusception, pancreatitis, obstructive jaundice, and death.6-8 The diagnosis of a gastric bezoar can be made using plain films, ultrasound, or CT, and

    Introduction: MALT lymphoma arises in a variety of body tissues, but most often in the stomach. Though relatively rare, these MALT lymphomas may arise within several sites in the head and neck, and often present diagnostic and therapeutic challenges. Immunohistochemical analysis are helpful in confirming the diagnosis between the MALT-lymphoma and the reactive lymphoid hyperplasia. MALT-type lymphoma demonstrated characteristic negative staining for CD3, CD5 and CD43, positive staining for CD20, and monotypic staining for either kappa or lambda light chain immunoglobulin markers, whereas reactive lymphoid hyperplasia all expressed Band T cell markers. Material and Methods: 41 cases of nasopharyngeal masses were obtained from the files at pathology department, Mansoura Faculty of Medicine through the period from 2002 till 2006. 31 cases were corresponded histomorphologically to low-grade B-cell lymphoma of mucosa associated lymphoid tissue (MALT) type and 10 patients with reactive lymphoid hyperplasia of the adenoid. Hematoxylin-eosin-stained slides were reviewed to confirm the diagnosis. Immunohistochemical studies were performed on formalin-fixed, paraffin-embedded sections using the labeled streptavidin-biotin-peroxidase complex method with DAB as chromogen. The following antibodies were evaluated CD20, CD3, Kappa, lambda and cytokeratin antibodies. Results: All cases of low grade MALT lymphoma show Iymphoepitheliallesion and proliferation of centrocyte like cells. 14 cases (45.1 %) show subepithelial plasma cells. Dutcher bodies were demonstrated in 10 cases (32.2%). Monocytoid B-cells were seen in 12 cases (38.7%). Six (60%) out of the ten cases of adenoids show transmigrating lymphocyte without formation of lymphoepithelial lesion. All cases with MALT-type lymphoma expressed CD20 and not CD3 whereas 10 cases of adenoid, all expressed Band T cell markers. Immunohistochemical staining showed that 31 cases of low grade MALT lymphoma were positive for immunoglobin

    Several coexisting diseases have been reported in patients with moyamoya vasculopathy (MMV), but studies of quasi-moyamoya disease (quasi-MMD) are rare. This study aims to investigate the frequency of known coexisting diseases in patients with quasi-MMD and to compare quasi-MMD with moyamoya disease (MMD). Between 2000 and 2011, we retrospectively screened patients with International Classification of Diseases, Ninth Revision, code of 4375 (MMD) in the Health Information System of our hospital. The vascular images of each patient were confirmed by 2 neurologists and 1 neuroradiologist based on the diagnostic criteria of Japan Ministry of Health and Welfare. We excluded the patients with missing images and erroneous diagnosis. Demographics, coexisting diseases, laboratory data, treatment, and recurrent strokes were recorded. The eligible patients were divided into quasi-MMD and MMD groups according to the presence or absence of coexisting diseases. MMV was found in 90 patients including 37 (41.1%) quasi-MMD and 53 (58.9%) MMD. Atherosclerosis (32.4%) and thyroid disease (29.7%) were the leading coexisting diseases in quasi-MMD. Patients with MMD became symptomatic in a bimodal age distribution, whereas patients with quasi-MMD became symptomatic in a single-peak distribution. The prognosis of recurrent strokes was similar between quasi-MMD and MMD based on Kaplan-Meier analysis. A bimodal distribution of onset age was noted in MMD, whereas a single-peak distribution was found in quasi-MMD. Coexisting diseases were usually underevaluated but were more common than expected in patients with MMV. Atherosclerosis and thyroid diseases were the leading coexisting diseases in different preferential age. Copyright © 2014 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    Full Text Available The main parameters of fermentation of whey-malt wort with the use of different strains of lactose-fermentation yeast was investigated experimentally. According to the findings of investigation of fermentive activity for different types of lactose-fermentation microorganisms in whey-malt wort it was found that the most active spirituous fermentation for all parameters was in wort fermented by microorganisms Zygosaccharomyces lactis 868-K and Saccharomyces lactis 95. High capacity for utilization of malt carbohydrates represented by easily metabolized carbohydrates of malt extract was determined. Also organoleptic analysis of fermented whey drinks derived from the renewed mixtures of dry whey and fermented malt and yeast Zygosaccharomyces lactis 868-K and Saccharomyces lactis 95 was carried out. It was found that the drink fermented with yeast Zygosaccharomyces lactis 868-K had intense refreshing flavor of rye bread with fruit tones. Intensity growth of aromatization for complex of sample with microorganisms Saccharomyces lactis 95, indicating high organoleptic indexes of the drink was observed.

    Full Text Available Rectal mucosa-associated lymphoid tissue (MALT lymphoma is a rare condition. Although the majority of patients undergo surgical resection, a definitive treatment for rectal MALT lymphoma has not yet been established. In the present study, we report the outcome of radiotherapy in 3 patients with rectal MALT lymphoma. Our cohort ranged from 56 to 65 years of age. The male/female ratio was 1:2, and all patients were in stage I (Lugano classification of the disease. Endoscopic findings revealed elevated lesions resembling submucosal tumors in 2 patients, and a sessile elevated lesion with a nodular surface in 1 patient. One of the 3 patients underwent magnifying endoscopy with crystal violet staining that demonstrated a type I pit pattern (Kudo’s classification lesion with a broad intervening area caused by the upthrust of the tumor from the submucosa. All patients tolerated radiotherapy at doses of 30 Gy without major complications and achieved complete remission. Follow-up ranged from 13 to 75 months (mean 51.0 months, revealing no recurrence of MALT lymphoma. As such, we propose radiotherapy to be a safe and effective means for treating rectal MALT lymphoma.

    Full text: Mucosa associated lymphoid tissue (MALT lymphoma) of the urinary bladder is a rare condition. The best treatment approach for this disease is controversial. A case report on a patient with MALT lymphoma of the urinary bladder. The relevant current literature was reviewed. A 79 year old lady presented with haematuria in 2002. Ultrasound of the pelvis showed a large tumour in the bladder. Cystoscopy revealed a mass arising from the bladder. Transurethral resection of the tumour was performed. Histology showed Non Hodgkin's lymphoma of MALT type. CT showed a 8.9 X 7.6 cm solid tumour involving almost whole of the bladder. The patient could not tolerate anti helicobacter treatment and was then treated with radiotherapy. The pelvis was treated with 18 MV photons with a 3 field technique in 2 phases, with CT planning. In phase 1, the pelvis was treated to 24 Gy in 12 fractions, over 2.5 weeks. Phase 2 was treated to a reduced pelvic field, to a dose of 16 Gy in 8 fractions over 1.5 weeks. Five months after radiotherapy, repeat cystoscopy and biopsy of bladder base showed no evidence of malignancy. MALT lymphoma of the urinary bladder responds well to radiotherapy and permits bladder preservation. The current literature in management of MALT lymphoma of urinary bladder is reviewed

    Medication adherence is an important determinant of transplant outcomes. Attempts to investigate adherence are frequently undermined by selection bias: It is very hard to recruit and retain non-adherent patients in research efforts. This manuscript presents recruitment strategies and results from the MALT (Medication Adherence in children who had a Liver Transplant) multisite prospective cohort study. MALT sites recruited 400 pediatric liver transplant patients who agreed to be followed for 2 years. The primary purpose was to determine whether a marker of adherence, the Medication Level Variability Index (MLVI), predicts rejection outcomes. The present manuscript describes methods used in MALT to ensure that a representative sample was recruited, and presents detailed recruitment results. MALT sites were able to recruit a nationally representative sample, as determined by a comparison between the MALT cohort and a national sample of transplant recipients. Strategies that helped ensure that the sample was representative included monitoring of the outcome measure in comparison with a national sample, drastically limiting patient burden, and specific recruitment methods. We discuss the importance of a representative sample in adherence research and recommend that future efforts to study adherence pay special attention to sample characteristics. © 2017 John Wiley & Sons A/S.

    Full Text Available CD95 (Fas/APO-1-mediated apoptosis plays an important role in immunological regulation and is related to the pathogenesis of autoimmune diseases. Immunoexpression of CD95 has been reported to frequently occur in low grade non-Hodgkin lymphomas, especially of post-germinal center histogenesis, among which those originating in mucosa-associated lymphoid tissue (MALT lymphomas. However, there is no report comparing in situ immunoexpression of this marker in lymphomas and the hyperplastic lymphoid reaction (chronic gastritis related to Helicobacter pylori infection. The purpose of the present research was to compare the intensity of lymphoid CD95 immunoexpression in 15 cases of H. pylori-related chronic gastritis and 15 gastric MALT lymphomas. CD95 (anti-CD95 was detected by an immunoperoxidase technique in paraffin sections using the catalyzed amplification system. Graduation of reaction intensity (percentage of CD95-positive cells was semiquantitative, from 1+ to 4+. Nine cases of chronic gastritis were 4+, five 2+ and one 1+. Three lymphomas were 4+, three 3+, four 2+, four 1+, and one was negative. Although 14 of 15 lymphomas were positive for CD95, the intensity of the reaction was significantly weaker compared to that obtained with gastric tissue for patients with gastritis (P = 0.03. The difference in CD95 immunoexpression does not seem to be useful as an isolated criterion in the differential diagnosis between chronic gastritis and MALT lymphomas since there was overlapping of immunostaining patterns. However, it suggests the possibility of a pathogenetic role of this apoptosis-regulating protein in MALT lymphomas.

    2010-01-01

    Nuclear shape change and shape coexistence in the Selenium isotopes have been investigated by Total-Routhian-Surface (TRS) calculations. It is found that nuclear shapes vary significantly with increasing neutron number. The TRS calculations for the ground states of 66,72,92,94 Se isotopes show that both neutron-deficient and neutron-dripline Selenium isotopes have oblate and prolate shape coexistence. The cranking shell-model calculations for 72,94 Se give that prolate and oblate shape coexistence in low rotational frequency. However, oblate rotational bands disappear and prolate rotational bands become yrast bands with increasing rotational frequency, which is due to the intrusion of the g 9/2 orbitals. (authors)

    The barley 0601 is a spontaneous albino-lemma mutant from beer barley cultivar Supi3. Genetic control of albino-lemma trait in the mutant 0601 and, the agronomic traits (thousand kernel weight, kernel plumpness), physiological traits (chlorophyll content, proanthocyanidin content) and major malt qualities (diastatic power, malt extract, Kolbach index) were investigated. The results showed that the albino-lemma trait is controlled by one recessive gene, and there were significant differences between the mutant and its wild-type in thousand kernel weight, kernel plumpness, chlorophyll content, diastatic power, and the malt extract, whereas no significant difference in proanthocyanidin content was found. These results provide the basis on mapping and cloning the albino-lemma gene and also provide good material for genetic research. (authors)

    Full Text Available We report a case of a 4-week-old female neonate with Jeune's asphyxiating thoracic dystrophy (JATD and coexistent situs anomaly, primarily presenting as gastric motility disorder. The child presented with abdominal distension and nonbilious vomiting since birth with failure to thrive. However, skeletal survey revealed JATD. Upper gastrointestinal contrast study showed situs inversus with delayed gastric emptying. Pyloric biopsy and intraoperative antro-duodenal manometry confirmed association of gastric motility disorder. Awareness of the unusual possibility of primary presentation of Jeune syndrome as gastric motility disorder will improve the management approach in such infants.

    Full Text Available Starches were isolated from soaked and malted sorghum and studied to understand their physicochemical and functional properties. The swelling power (SP and the water solubility index (WSI of both starches were nearly similar at temperatures below 50 °C, but at more than 50 °C, the starch isolated from malted sorghum showed lower SP and high WSI than those isolated from raw and soaked sorghum. The pasting properties of starches determined by rapid visco-analyzer (RVA showed that malted sorghum starch had a lower viscosity peak value (86 BU/RVU than raw sorghum starch (454 BU/RVU. For both sorghum, X-ray diffractograms exhibited an A-type diffraction pattern, typical of cereal starches and the relative degrees of crystallinity ranged from 9.62 to 15.50%. Differential scanning calorimetry (DSC revealed that raw sorghum starch showed an endotherm with a peak temperature (Tp at 78.06 °C and gelatinization enthalpies of 2.83 J/g whereas five-day malted sorghum starch had a Tp at 47.22 °C and gelatinization enthalpies of 2.06 J/g. Storage modulus (G′ and loss modulus (G″ of all starch suspensions increased steeply to a maximum at 70 °C and then decreased with continuous heating. The structural analysis of malted sorghum starch showed porosity on the granule’s surface susceptible to the amylolysis. The results showed that physicochemical and functional properties of sorghum starches are influenced by soaking and malting methods.

    Full Text Available Recently, the traditional formulations of essential food products are actively including malt – a valuable dietary product rich in extractives and hydrolytic enzymes, obtained by germination in artificially created conditions. Containing a full set of essential amino acids and a high saccharifying ability of malt, obtained from grain cereals, determines its wide use in the production of beer, alcohol, mono- and poly-malt extracts, bakery products, special types of flour, food additives, cereals, non-alcoholic beverages, lactic acid products and, in particular, in the production of natural coffee substitutes. However, the classical germination technology, which includes 2-3 days of soaking and 5-8 days of germination due to the considerable duration and laboriousness of the process, does not meet the requirements of modern technology and the constantly growing rates of industrial production, so this problem requires finding new and improving existing scientific and technical solutions. The features of malt production using organic acids of different concentrations are presented. The malt production technology has been analyzed and investigated. It includes washing, disinfection, air and water soaking of grains, germination and drying. The feature of the technology under investigation is using of aqueous solutions of butadiene, 3-pyridinecarboxylic acid and pteroylglutamic acid. The results of the inquiry of the effect of these organic acids on energy and the ability of germination of the grain are presented. The optimal values of concentrations of active substances in solutions are revealed. The influence of organic acids on the absorption of grain moisture has been investigated. It has been established that in comparison with the classical technology, the use of these acids as a growth stimulator can reduce the overall length of the reproduction process of the material from 1.5 to 2 times and increase the yield of flour grains in the batch of

  7. MALT lymphoma and concurrent adenocarcinoma of the prostate: a rare case report and review of the literature.

    Full Text Available Primary MALT lymphoma of the prostate is a rare disease which characteristically follows an indolent course. It is believed that infection or chronic inflammation may be triggers for malignant transformation in the prostate, but it is of unknown etiology. Reports of MALT lymphomas of the prostate with other concurrent primary prostate cancers are even more limited. We present the unique case of a 67 year old male with concurrent adenocarcinoma of the prostate and primary MALT lymphoma of the prostate. The patient was treated with standard therapy for prostate adenocarcinoma, which also sufficiently would treat a primary MALT lymphoma. He has been disease-free for over one year for both his primary malignancies. This case confirms that MALT lymphoma can arise concurrently with adenocarcinoma of the prostate.

    Full Text Available In order to study the influence of mycotoxins on the production of alcohols, a fermentative process on a laboratorial scale was simulated. Malt was contaminated with deoxynivalenol and T-2 in different ratios (up to 500 ppb, according to a 3² factorial design, and the alcohols obtained after the fermentation were determined through gas chromatography. The results showed that trichothecenes influenced the profile of the alcohols produced by Saccharomyces cerevisiae during the fermentative process of malt, especially the profile of methyl and isoamyl alcohols.

    Alterations in the immune response of patients with autoimmune diseases may predispose to malignancies, and a link between chronic autoimmune gastritis and gastric cancer has been reported in many studies. Intestinal metaplasia with dysplasia of the gastric corpus-fundus mucosa and hyperplasia of chromaffin cells, which are typical features of late-stage autoimmune gastritis, are considered precursor lesions. Autoimmune gastritis has been associated with the development of two types of gastric neoplasms: intestinal type and type I gastric carcinoid. Here, we review the association of autoimmune gastritis with gastric cancer and other autoimmune features present in gastric neoplasms. PMID:29373557

    Objective: To analyze the clinical results and prognostic factors of patients with early-stage primary gastric mucosa-associated lymphoid tissue (MALT) lymphoma. Methods: Seventy-seven patients with primary gastric MALT lymphoma treated from 1985 to 2006 were retrospectively analyzed. All patients were pathologically confirmed as MALT lymphoma in stage I, II and II E (by modified Blackedge staging system). Thirty-seven patients had stage I disease, 23 stage II and 17 stage II E . Sixty patients underwent surgical resection and 17 received non-surgical treatment. Survival rates were calculated by the Kaplan-Meier analysis with the Logrank test. Results: With a median follow up of 57 months for the surviving patients (ranging from 1 to 198 months for all patients), the 5-year overall survival rate, disease-free survival rate, loco-regional control rate and distant metastasis free survival rate were 74%, 70%, 76% and 87%, respectively. In univariate analysis, clinical stage was significantly associated with overall survival. Patients with stage I or II disease had a better overall survival than those with stage II E (P=0.01). Tumor size and surgical resection were significantly associated with disease-free survival. Patients with primary tumor 8 cm or less in diameter had better disease-free survival than those with primary tumor more than 8 cm in diameter (P =0.03). Patients who underwent complete resection had better disease-free survival than those who underwent incomplete resection or no surgery (P=0.02). Clinical stage, tumor size and surgical resection were significantly associated with loco-regional control. Patients with stage I or II disease had better loco-regional control than those with stage II E (P=0.03). Patients with primary tumor 8 cm or less in diameter had better loco-regional control than those with primary tumor more than 8 cm in diameter (P=0.01). Patients who underwent complete resection had better loco-regional control than those who underwent

    Full Text Available In the brewing process, barley malt is used as main raw material. Sorghum is one of the most suitable cereals to replace barley because of its high nutritional value. However, the sorghum beer supply is still insufficient in the global market due to the low quality of its malt. The aim of this research was to study the development of free amino nitrogen (FAN during sorghum malting for brewing process by using Response Surface Methodology (RSM. A Central Composite Rotatable Design (CCD was used to develop a statistical model for the optimization of process variables such as NaOH concentration (0,2 - 0,5%(w/v, steeping time (12 - 36 h, and germination time (48 - 72 h. Data obtained from RSM on FAN production were subjected to the analysis of variance (ANOVA and were analyzed using a second order polynomial equation. Optimum malting conditions for the highest FAN value (350,00 mg L-1 were: NaOH concentration 0,35%, steeping time 26 h and germination time 63 h.

    To learn how the local context may affect a city's ability to regulate alcohol products such as high-alcohol-content malt liquor, a beverage associated with heavy drinking and a spectrum of nuisance crimes in urban areas. An exploratory, qualitative case study comparing cities that adopted policies to restrict malt liquor sales with cities that considered, but did not adopt policies. Nine large U.S. cities in seven states. City legislators and staff, alcohol enforcement personnel, police, neighborhood groups, business associations, alcohol retailers, and industry representatives. Qualitative data were obtained from key informant interviews (n = 56) and media articles (n = 360). The data were coded and categorized. Similarities and differences in major themes among and across Adopted and Considered cities were identified. Cities faced multiple barriers in addressing malt liquor-related problems, including a lack of enforcement tools, alcohol industry opposition, and a lack of public and political will for alcohol control. Compared to cities that did not adopt malt liquor sales restrictions, cities that adopted restrictions appeared to have a stronger public mandate for a policy and were less influenced by alcohol industry opposition and lack of legislative authority for alcohol control. Strategies common to successful policymaking efforts are discussed. Understanding the local context may be a critical step in winning support for local alcohol control policies.

  18. Ronald Malt or Chen Zhongwei: Who performed the first surgical replantation?

    Science.gov (United States)

    Fan, Ka-Wai

    2018-01-01

    This article discusses the contributions of the two pioneers of the surgical procedure of replantation-Ronald Malt in the US and Chen Zhongwei in China. Ronald Malt performed the reattachment surgery on a boy who had an accident in 1962, but he published his case report two years later in 1964. Chen Zhongwei performed a similar surgery on a worker who cut off his forearm in 1963, but he published his case report the same year. There is some debate about which one of these reputed surgeons should be given credit for being the first one to perform this breakthrough surgery, because although Malt was the first to perform the procedure, Zhongwei was the first to report it. To shed light on this controversy, criteria for scientific priority suggested by Ronald Vale and Anthony Hyman were applied. Although the criteria mainly favored Zhongwei as the pioneer of this procedure, he did not entirely fulfill one of the criteria. Therefore, the article could not present a definitive answer to the question, and it concludes by pointing out the highly commendable achievements and contributions of both Ronald Malt and Chen Zhongwei.

    Mucosal surface nodularity was defined as present at UGIS when multiple nodular defects larger than 5 mm were scattered in the gastric mucosa in an area greater than 5 x 5 cm. The purpose of this study was to determine the primary causes of this radiographic finding and to assess the incidence of gastric malignancy in these patients. During a one-year period were prospectively collected among patients who underwent UGIS, data for 51 [aged 30-78 (mean, 51) years] above who met the criteria of mucosal surface nodularity. Whether or not this was present was decided by two radiologists who in reaching a consensus excluded the possibility of erosive gastritis, indicated by central barium collection in the nodular defects. The primary causes of mucosal nodularity and associated gastric pathologies were determined by the histopathological results obtained from the specimens after surgery (n=18) or endoscopic biopsy (n=33). Pathological examinations revealed that the primary causes of the mucosal nodularity in these 51 patients were intestinal metaplasia in 28 (54.9%), MALT lymphoma in seven (13.7%), early gastric cancer in six (11.8%), chronic gastritis in five (9.8%), low grade dysplasia in four (7.8%), and gastritis cystica profunda in one (2%). Gastric malignancy was present either in or outside the area of mucosal nodularity in 34 (66/7%) of the 51 (27 carcinomas and 7 MALT lymphomas). No different patterns of mucosal surface nodularity were noted between the groups of each disease entity. Mucosal surface nodularity is observed at UGIS in various gastric pathologies. Because of the high incidence of gastric malignancy in these patients, close follow-up or gastrofiberscopic biopsy is mandatory.

    Intrahepatic cholangiocarcinoma (CCA) is an aggressive cancer that lacks an effective targeted therapy. Here, we assessed the therapeutic efficacy of regorafenib in CCA, as well as elucidated its underlying mechanism. We first demonstrated that regorafenib not only inhibited growth but also induced apoptosis in human CCA cells. Subsequently, we used in silico approaches to identify MALT1 (Mucosa-associated lymphoid tissue protein 1), which plays an important role in activating NF-κB, as a potential target of regorafenib. Overexpression of Elk-1, but not Ets-1, in HuCCT1 cells markedly reduced their sensitivity to regorafenib, which might be attributed to a significant increase in MALT1 levels. Our results further demonstrated that this drug drastically inhibited MALT1 expression by suppressing the Raf/Erk/Elk-1 pathway. The efficacy of regorafenib in decreasing in vivo CCA growth was confirmed in animal models. Regorafenib efficacy was observed in two MALT1-positive CCA patients who failed to respond to several other lines of therapy. Finally, MALT1 was also identified as an independent poor prognostic factor for patients with intrahepatic CCA. In conclusion, our study identified MALT1 to be a downstream mediator of the Raf/Erk/Elk-1 pathway and suggested that MALT1 may be a new therapeutic target for successful treatment of CCA by regorafenib.

    The consumption of beverages contributes to diet quality and overall nutrition. Studies on malted drinks, one of the widely consumed beverage choices among children in Asia, however, have received limited attention. This study aimed to examine the prevalence of malted drink consumption and explored associations of sociodemographic characteristics, nutrient intakes, weight status and physical activity levels with malted drink consumption among primary school children in Malaysia. Data for this analysis were from the MyBreakfast Study, a national cross-sectional study conducted from April to October 2013 throughout all regions in Malaysia. A total of 2065 primary school children aged 6 to 12 years were included in the present analysis. Data on two days 24-h dietary recall or record, anthropometry, physical activity and screen time were recorded. Associations between malted drink consumption and related factors were examined using binary logistic regression, adjusting for region, area, gender, ethnicity and household income. Among children aged 6 to 12 years, 73.5% reported consuming malted drinks for at least once per week. Consumption of malted drinks was significantly associated with region (χ(2) = 45.64, p Malaysian primary school children, particularly higher among boys, indigenous children and those who lived in the East Coast region of Malaysia. Consuming malted drinks is associated with higher micronutrient intakes and higher levels of physical activity, but not with body weight status.

    Both histologic chorioamnionitis (HCAM) and Ureaplasma infection are considered important contributors to perinatal lung injury. We tested the hypothesis that coexistence of maternal HCAM and perinatal Ureaplasma exposure increases the risk of prolonged mechanical ventilation in extremely low-birthweight (ELBW) infants. A retrospective cohort study was carried out of all ELBW infants born between January 2008 and December 2013 at a single academic center. Placental pathology and gastric fluid Ureaplasma data were available for all infants. Culture and polymerase chain reaction were used to detect Ureaplasma in gastric fluid. Prolonged mechanical ventilation was defined as mechanical ventilation that began within 28 days after birth and continued. Of 111 ELBW infants enrolled, 84 survived beyond 36 weeks of postmenstrual age (PMA) and were included in the analysis. Eighteen infants (21.4%) had both HCAM and Ureaplasma exposure. Seven infants (8.3%) required mechanical ventilation beyond 36 weeks of PMA. Coexistence of HCAM and Ureaplasma in gastric fluid was significantly associated with prolonged mechanical ventilation after adjustment for gestational age, sex, mode of delivery, and use of macrolide antibiotics (OR, 8.7; 95%CI: 1.1-67.2). Coexistence of maternal HCAM and perinatal Ureaplasma exposure significantly increases the risk of prolonged mechanical ventilation in ELBW infants. © 2016 Japan Pediatric Society.

    Full Text Available The feasibility of partially replacing wheat flour with malted rice flour in bread making was evaluated in several formulations, aiming to find a formulation for the production of malted rice-wheat bread with better nutritional quality and consumer acceptance. The whole grains of a local rice variety (Oryza sativa L. subsp. indica var. Mottaikaruppan were steeped in distilled water (12 h, 30°C and germinated for 3 days to obtain high content of soluble materials and amylase activity in bread making. The quality of bread was evaluated by considering the physical and sensorial parameters. When the wheat flour was substituted with malted rice flour, 35% substitution level and the malted rice flour from 3 days of germination was the best according to the physical and sensory qualities of bread. The quality of bread was improved by the addition of 20 g of margarine, 20 g of baking powder and 20 g of yeast in 1 kg of flour. Among different ratios of yeast and baking powder, 2:1 was the best. Bread improver containing amylases and oxidizing agents at the concentration of 40 g/kg was selected as the best concentration. When comparing the final formulation made in the bakery with wheat bread, malted rice-wheat bread contains more soluble dietary fiber (0.62%, insoluble dietary fiber (3.95%, total dietary fiber (4.57% and free amino acid content (0.64 g/kg than those in wheat bread (0.5%, 2.73%, 3.23% and 0.36 g/kg, respectively.

  9. Can magnetism and superconductivity coexist

    1982-01-01

    Recent syntheses of rare earth (RE) ternary superconductors such as (RE)Mo 6 X 8 (X=S or Se) and (RE)Rh 4 B 4 have provided the first opportunity to explore the interaction between magnetism and superconductivity in detail owing to their particular crystal structure. The regular sublattice of the rare-earth ions in these new ternary compounds undergoes a ferro- or antiferromagnetic phase transition in the superconducting state. If the transition is antiferromagnetic, the superconductivity is preserved so that true coexistence results. If it is ferromagnetic, on the other hand, the superconductivity eventually gives way to uniform ferromagnetism at low temperatures. However, recent theories predict several possible states of coexistence even in ferromagnetic superconductors. This article reviews aspects of these new phase transitions in ternary superconductors.

    The high-spin states in 153Ho have been studied by the La57(20Ne139,6 n ) reaction at a projectile energy of 139 MeV at the Variable Energy Cyclotron Centre (VECC), Kolkata, India, utilizing an earlier campaign of the Indian National Gamma Array (INGA) setup. Data from γ -γ coincidence, directional correlation, and polarization measurements have been analyzed to assign and confirm the spins and parities of the levels. We have suggested a few additions and revisions of the reported level scheme of 153Ho. The RF-γ time difference spectra have been useful to confirm the half-life of an isomer in this nucleus. From the comparison of experimental and theoretical results, it is found that there are definite indications of shape coexistence in this nucleus. The experimental and calculated lifetimes of several isomers have been compared to follow the coexistence and evolution of shape with increasing spin.

    Gastric surgery is commonly performed to remove foreign bodies and correct gastric dilatation-volvulus and is less commonly performed to treat gastric ulceration or erosion, neoplasia, and benign gastric outflow obstruction. Intestinal surgery, although commonly performed by veterinarians, should never be considered routine. The most common procedures of the small intestinal tract performed in dogs and cats include enterotomy and resection/anastomosis. Surgery of the large intestine is indicated for lesions causing obstruction, perforations, colonic inertia, or chronic inflammation.

    The roentgenographic recognition of gastric varices often is difficult, even when there is a history of liver disease or splenomegaly without demonstrable esophageal varices. An apparant polypoid filling defect with exaggerated mucosal folds in proximal portion of the gastric body and funds on upper GI series, accompanied by hematemesis and splenomegly should suggest the presence of pseudotumoral gastric varices. We have an experience a case of polypoid filling defects in gastric fundus of psudotumoral gastric varices of 49 years old Korean woman, which was diagnosed by surgical and histopathological findings

    Full Text Available Os linfomas extralinfonodais representam aproximadamente 1/3 de todos os linfomas não Hodgkin (LNH e, embora possam ter início em qualquer tecido, mais frequentemente acometem o trato gastrointestinal, sendo o estômago o órgão responsável pela grande maioria dos casos. Os linfomas primários gástricos são comumente LNH, sendo representados em mais de 95% dos casos pelo linfoma difuso de grandes células B e pelo linfoma MALT (mucosa associated lymphoid tissue. De evolução indolente, o linfoma MALT destaca-se por ser um modelo de câncer secundário à estimulação antigênica crônica exercida por uma bactéria denominada Helicobacter pylori (HP. No outro polo, situa-se o linfoma difuso de células B (LDGCB, que, de patogênese duvidosa, pode tratar-se de uma transformação de LNH MALT ou ainda se caracterizar por um linfoma "de novo". Neste estudo, revisamos a literatura, enfatizando aspectos importantes à prática clínica destes linfomas.Extranodal lymphomas account for about 30% of all non-Hodgkin lymphomas (NHL, and although they can originate in any tissue, the gastrointestinal tract is the most commonly affected structure with the stomach being the most common subtype. Diffuse Large B cell lymphoma (DLBCL and MALT (mucosa associated lymphoid tissue lymphoma account for more than 95% of the cases of gastric lymphoma. The indolent development of MALT lymphoma stands out as it is a type of cancer subject to chronic antigen stimulation by the Helicobacter pylori bacteria. Conversely, diffuse large B cell lymphomas, whose pathogenesis is uncertain, can be a transformation from MALT NHL or perhaps a new type of lymphoma. In this study we carried out a review of the literature, stressing the key aspects of these lymphomas in the clinical practice.

    2000-01-01

    Analysis of husked barleys for proanthocyanidins and malt quality attributes has shown that not a single variety is free of proanthocyanidins. The proanthocyanidins in barley grains varied from 3.85 to 4.94 mg/g as catechin equivalent. The concentration of proanthocyanidins decreased, while total soluble sugars, reducing sugars, diastatic power and beta-amylase activity increased during maltings as well as with exogenous gibberellic acid (GA3) application. Alfa 93 (two-row) and RD2560 (six-row) varieties appeared to be superior for malting and brewing purposes on the basis of proanthocyanidins, total phenols, diastatic power and beta-amylase activity. It is suggested that exogenous application of GA3 at 15 ppm may be useful for producing good quality malt from barley grains.

    Chlorella vulgaris is a unicellular and microscopic algae that is currently used in a variety of forms of tablets, capsules and liquid as a biological response modifier. The aim of this study was to investigate the effects of hydrolyzed Chlorella vulgaris by malted barley for its potential reduction of the immobility time in ICR mice and on the cytokine regulation in human T cell line, Molt-4. After a forced swimming test, the changes in aspects of blood biochemical parameters due to the administration of hydrolyzed Chlorella vulgaris by malted barley were examined. The effect of hydrolyzed Chlorella vulgaris by the malted barley-treated group for 14 days on the immobility time was significantly reduced in comparison with that of the control group (P cells. These results indicate that hydrolyzed Chlorella vulgaris by malted barley is useful for immune function improvements, enhanced physical stamina, and as a candidate for an anti-fatigue or antidepressant agent.

    A method was developed to determine pesticides in malt beverages using solid phase extraction on a polymeric cartridge and sample cleanup with a MgSO4-topped aminopropyl cartridge, followed by capillary gas chromatography with electron impact mass spectrometry in the selected ion monitoring mode [GC-MS(SIM)]. Three GC injections were required to analyze and identify organophosphate, organohalogen, and organonitrogen pesticides. The pesticides were identified by the retention times of peaks of the target ion and qualifier-to-target ion ratios. GC detection limits for most of the pesticides were 5-10 ng/mL, and linearity was determined from 50 to 5000 ng/mL. Fortification studies were performed at 10 ng/mL for three malt beverages that differ in properties such as alcohol content, solids, and appearance. The recoveries from the three malt beverages were greater than 70% for 85 of the 142 pesticides (including isomers) studied. The data showed that the different malt beverage matrixes had no significant effect on the recoveries. This method was then applied to the screening and analysis of malt beverages for pesticides, resulting in the detection of the insectide carbaryl and the fungicide dimethomorph in real samples. The study indicates that pesticide levels in malt beverages are significantly lower than the tolerance levels set by the United States Environmental Protection Agency for malt beverage starting ingredients. The use of the extraction/cleanup procedure and analysis by GC-MS(SIM) proved effective in screening malt beverages for a wide variety of pesticides. Copyright 2004 American Chemical Society

    Full Text Available Malting quality comprises one of the most economically relevant set of traits in barley ( L.. It is a complex phenotype, expensive and difficult to measure, that would benefit from a marker-assisted selection strategy. Malting quality is a target of the U.S. Barley Coordinated Agricultural Project (CAP and development of winter habit malting barley varieties is a key objective of the U.S. barley research community. The objective of this work was to detect quantitative trait loci (QTL for malting quality traits in a winter breeding program that is a component of the U.S. Barley CAP. We studied the association between five malting quality traits and 3072 single nucleotide polymorphisms (SNPs from the barley oligonucleotide pool assay (BOPA 1 and 2, assayed in advanced inbred lines from the Oregon State University (OSU breeding program from three germplasm arrays (CAP I, CAP II, and CAP III. After comparing 16 models we selected a structured association model with posterior probabilities inferred from software STRUCTURE (QK approach to use on all germplasm arrays. Most of the marker-trait associations are germplasm- and environment-specific and close to previously mapped genes and QTL relevant for malt and beer quality. We found alleles fixed by random genetic drift, novel unmasked alleles, and genetic-background interaction. In a relatively small population size study we provide strong evidence for detecting true QTL.

    Report a case of satisfactory progress radiation retinopathy after radiation for mucosa-associated lymphoid tissue (MALT) lymphoma. A 26-year-old male patient, referred to our department for lacrimal sac tumor. Biopsy was done by otolaryngology and radiation therapy was performed (total irradiation of 41.4 Gy) as pathological examination revealed MALT lymphoma. Soft exudates and macula edema appeared in posterior pole of the right fundus after radiotherapy. Right vision became 0.5 because of macula edema, and panretinal photocoagulation (PRP) was performed. After PRP, macula edema withdrew and right vision improved to 1.2. It is suggested that the fundus must be monitored after radiation therapy, and early treatment, such as PRP is effective in radiation retinopathy. (author)

    Two einkorn wheat, one barley, three optional winter cultivation wheat and five winter cultivation wheat samples harvested in Hungary in 2011, and their malts were evaluated for their DPPH radical and ABTS radical cation scavenging activity, ferric reduction capacity (FRAP) and total phenolic content (TPC). All einkorn and barley samples exhibited significant antioxidant activities determined by DPPH and ABTS radical scavenging activities. The einkorn samples show higher polyphenol content than the other wheat samples. In all cases the barley sample had the highest antioxidant potential and polyphenol content. The einkorn malts had high DPPH and ABTS radical cation scavenging activities, but the phenolic content was lower against wheat samples. There was significant difference between the antioxidant potential of optional and winter cultivation wheat samples except on ABTS scavenging activities. Einkorn wheat is potentially a new raw material to produce organic beer that might have beneficial effects with its increased antioxidant potential. Copyright © 2014 Elsevier Ltd.

    Full Text Available  In this study, sorghum Feterita malt extract was used to prepare carbonated beverages flavored with traditional Hulu-mur spices extract.  The beverages produced were assessed for their physicochemical, sensory, and nutritional qualities. Malting (3–5 days of the Feterita grains showed significant (P ≤ 0.05 differences in proximate composition from that of unmalted grains. Protein and sugars increased significantly (P ≤ 0.05 with increased the malting time (days, while there was a significant (P ≤ 0.05 reduction in oil and starch  content  during malting progress. The kilning temperature of 150°C for 20 minutes was found to produce the most acceptable Hulu-mur carbonated beverage analogue in terms of flavor and taste. Significant differences (P ≤ 0.05 were observed in physicochemical and nutritional qualities between the Hulu-mur analogue carbonated beverage and commercial non-alcoholic beverage. The Hulu-mur carbonated beverage analogue was rich in Na, K, Ca, and Fe (26.45, 21.84, 24.00, and 0.57 mg /100 g, respectively compared to levels of the same minerals in the non-alcoholic beverage (22.31, 8.19, 22.00 and 0.15 mg/100 g, respectively. The Hulu-mur analogue also had a higher calorific value (35.85 kcal /100 mL compared to the non-alcoholic beverage (32.96 kcal/100 mL.

  3. Cell wall polysaccharides hydrolysis of malting barley (Hordeum vulgare L.: a review

    Directory of Open Access Journals (Sweden)

    Jamar, C.

    2011-01-01

    Full Text Available Malting quality results from the different steps of the malting process. Malting uses internal changes of the seed occurring during germination, such as enzymes synthesis, to obtain a good hydrolysis process and the components required. Among the three main hydrolytic events observed, that are namely starch degradation, cell wall breakdown and protein hydrolysis, an efficient cell wall polysaccharides hydrolysis is an essential condition for a final product of quality. Indeed, because of the physical barrier of the cell wall, cell wall polysaccharides hydrolysis is one of the first steps expected from the process to gain access to the cell components. Moreover, viscosity problem and haze formation in malting industry are related to their presence during the process when inefficient degradation occurs, leading to increased production time and cost. Understanding the key elements in cell wall degradation is important for a better control. (1-3,1-4-β-glucans and arabinoxylans are the main constituents of cell wall. (1-3,1-4-β-glucans are unbranched chains of β-D-glucopyranose residues with β-(1,3 linkages and β-(1,4 linkages. Arabinoxylan consists in a backbone of D-xylanopyranosyl units linked by β-(1-4 bonds connected to single L-arabinofuranose by α-(1→2 or α-(1→3-linkages. Degradation of (1-3,1-4-β-glucans is processed by the (1-3,1-4-β-glucanases, the β-glucosidases and the β-glucane exohydrolases. It seems that the (1-3-β-glucanases are also involved. Arabinoxylans are mainly decomposed by (1-4-β-xylan endohydrolase, arabinofuranosidase and β-xylosidase.

    The estimated volume of meal in the stomach 30 mins after sup(113m)In-DTPA administration was determined in patients with gastric ulcer and normal controls by 1) relating counts in the stomach to those in the whole field of view of the gamma camera and 2) aspirations. In the normal controls there was no significant difference between the two methods but in the gastric ulcer patients, the gamma camera method predicted significantly more meal in the stomach than was recovered by aspiration. It was suggested that the large low lying stomach found in gastric ulcer disease causes extensive overlap of the small bowel and invalidates measurements of gastric emptying made by a gamma camera.

    1985-01-01

    Seventy-six patients suffering from dyspeptic symptoms secondary to roentgenologically demonstrated delayed gastric emptying were treated with clebopride (0.5 mg TID) or with placebo during a three-month double-blind trial. Clebopride was more effective (P less than or equal to 0.001) than placebo in reducing or relieving symptoms and roentgenological findings associated with delayed gastric emptying. No interactions of clebopride with concomitant drugs or coexisting disorders were observed, and the incidence of side effects was low. We conclude that clebopride will be beneficial in the management of patients with delayed gastric emptying.

    The tandem accelerator in University of Tokyo, which was renewed from 1991 to March, 1994 started the joint utilization within the University since April, 1995 after about one year of the period of adjustment. The time of operation exceeding 3500 hours in one year was recorded. This facility is that for carrying out the minute analysis such as AMS, PIXE, NRA and others and the research of atomic and molecular physics, and called microanalysis laboratory-tandem accelerator (MALT). Support has been done by placing emphasis on the development of AMS measurement which enables the microanalysis of {sup 14}C,{sup 10}Be and {sup 26}Al, but the accuracy of {sup 14}C AMS did not attain the practical level. {sup 10}Be and {sup 26}Al AMS reached almost the practical level, and the measurement of actual samples has been carried out. The state of operation and utilization of the MALT is reported. As to the recent troubles and the countermeasures in the MALT, the voltage instability of the accelerator, the unstable ion source support mechanism and the poor transmissivity of beam in the accelerator are described.

    The roasting of barley and malt products generates colour and flavour, controlled principally by the time course of product temperature and moisture content. Samples were taken throughout the industrial manufacture of three classes of roasted product (roasted barley, crystal malt and black malt) and analysed for moisture content, colour and flavour volatiles. Despite having distinct flavour characteristics, the three products contained many compounds in common. The product concentrations through manufacture of 15 flavour compounds are used to consider the mechanisms (Maillard reaction, caramelisation, pyrolysis) by which they were formed. The use of water sprays resulted in transient increases in formation of certain compounds (e.g., 2-cyclopentene-1,4-dione) and a decrease in others (e.g., pyrrole). The study highlights rapid changes in colour and particularly flavour which occur at the end of roasting and onwards to the cooling floor. This highlights the need for commercial maltsters to ensure consistency of procedures from batch to batch. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Fusarium head blight (FHB) caused by Fusarium and Microdochium species can significantly affect the yield of barley grain as well as the quality and safety of malt and beer. The present study provides new knowledge on the impacts of the FHB pathogen complex on the malting and brewing quality parameters of naturally infected barley. Quantitative real-time PCR and liquid chromatography double mass spectrometry were used to quantify the predominant FHB pathogens and Fusarium mycotoxins, respectively, in commercially grown UK malting barley samples collected between 2007 and 2011. The predominant Fusarium species identified across the years were F. poae, F. tricinctum and F. avenaceum. Microdochium majus was the predominant Microdochium species in 2007, 2008, 2010 and 2011 whilst Microdochium nivale predominated in 2009. Deoxynivalenol and zearalenone quantified in samples collected between 2007 and 2009 were associated with F. graminearum and F. culmorum, whilst HT-2 and T-2, and nivalenol in samples collected between 2010 and 2011 correlated positively with F. langsethiae and F. poae, respectively. Analysis of the regional distribution and yearly variation in samples from 2010 to 2011 showed significant differences in the composition of the FHB species complex. In most regions (Scotland, the South and North of England) the harvest in 2010 had higher concentrations of Fusarium spp. than in 2011, although no significant difference was observed in the Midlands between the two years. Microdochium DNA was significantly higher in 2011 and in the North of England and Scotland compared to the South or Midlands regions. Pathogens of the FHB complex impacted negatively on grain yield and quality parameters. Thousand grain weight of malting barley was affected significantly by M. nivale and M. majus whilst specific weight correlated negatively with F. avenaceum and F. graminearum.

    To assess the clinical outcomes of radiotherapy (RT) using two-dimensional (2D) and three-dimensional conformal RT (3D-CRT) for patients with gastric mucosa-associated lymphoid tissue (MALT) lymphoma to evaluate the effectiveness of involved field RT with moderate-dose and to evaluate the benefit of 3D-CRT comparing with 2D-RT. Between July 2003 and March 2015, 33 patients with stage IE and IIE gastric MALT lymphoma received RT were analyzed. Of 33 patients, 17 patients (51.5%) were Helicobacter pylori (HP) negative and 16 patients (48.5%) were HP positive but refractory to HP eradication (HPE). The 2D-RT (n = 14) and 3D-CRT (n = 19) were performed and total dose was 30.6 Gy/17 fractions. Of 11 patients who RT planning data were available, dose-volumetric parameters between 2D-RT and 3D-CRT plans was compared. All patients reached complete remission (CR) eventually and median time to CR was 3 months (range, 1 to 15 months). No local relapse occurred and one patient died with second primary malignancy. Tumor response, survival, and toxicity were not significantly different between 2D-RT and 3D-CRT (p > 0.05, each). In analysis for dose-volumetric parameters, Dmax and CI for PTV were significantly lower in 3D-CRT plans than 2D-RT plans (p < 0.05, each) and Dmean and V15 for right kidney and Dmean for left kidney were significantly lower in 3D-CRT than 2D-RT (p < 0.05, each). Our data suggested that involved field RT with moderate-dose for gastric MALT lymphoma could be promising and 3D-CRT could be considered to improve the target coverage and reduce radiation dose to the both kidneys

    Animal aggregations are visually striking, and as such are popular examples of collective behavior in the natural world. Quantitatively demonstrating the collective nature of such groups, however, remains surprisingly difficult. Inspired by thermodynamics, we applied topological data analysis to laboratory insect swarms and found evidence for emergent, material-like states. We show that the swarms consist of a core "condensed" phase surrounded by a dilute "vapor" phase. These two phases coexist in equilibrium, and maintain their distinct macroscopic properties even though individual insects pass freely between them. We further define a pressure and chemical potential to describe these phases, extending theories of active matter to aggregations of macroscopic animals and laying the groundwork for a thermodynamic description of collective animal groups.

    Although the majority of gastric carcinomas are sporadic, approximately 10% show familial aggregation, and a hereditary cause is determined in 1%-3% cases. Of these, hereditary diffuse gastric cancer is the most recognized predisposition syndrome. Although rare, the less commonly known syndromes also confer a markedly increased risk for development of gastric cancer. Identification and characterization of these syndromes require a multidisciplinary effort involving oncologists, surgeons, genetic counselors, biologists, and pathologists. This article reviews the molecular genetics, clinical and pathologic features, surveillance guidelines, and preventive measures of common and less common hereditary gastric cancer predisposition syndromes. ©AlphaMed Press.

  17. Prebiotic and synbiotic effects on rats fed malted barley with selected bacteria strains

    Full Text Available Background: Butyric acid, one of the key products formed when β-glucans are degraded by the microbiota in the colon, has been proposed to be important for colonic health. Glutamine bound to the fibre may have similar effects once it has been liberated from the fibre in the colon. Both β-glucans and glutamine are found in high amounts in malted barley. Lactobacillus rhamnosus together with malt has been shown to increase the formation of butyric acid further in rats. Objective: To investigate whether Lactobacillus rhamnosus 271, Lactobacillus paracasei 87002, Lactobacillus plantarum HEAL 9 and 19, and Bifidobacterium infantis CURE 21 affect the levels of short-chain fatty acids and glutamine in caecum and portal blood of rats fed barley malt. Design: The experimental diets were fed for 12 days. The daily dose of the probiotic strain was 1×109 colony forming units and the intake of fibre 0.82 g/day. Results: The malt mostly contained insoluble fibre polymers (93%, consisting of glucose and xylose (38–41 g/kg and some arabinose (21 g/kg. The fibre polysaccharides were quite resistant to fermentation in the rats, regardless of whether or not probiotics were added (25–30% were fermented. Caecal and portal levels of acetic acid decreased in the rats after the addition of L. plantarum HEAL 9 and L. rhamnosus 271, and also the levels of butyric acid. Viable counts of Lactobacillus, Bifidobacterium and Enterobacteriaceae were unaffected, while the caecal composition of Lactobacilli was influenced by the type of strain administrated. Portal levels of glutamine were unchanged, but glycine levels increased with L. plantarum HEAL 9 and 19 and phenylalanine with L. rhamnosus 271. Conclusions: Although the probiotic strains survived and reached the caecum, except B. infantis CURE 21, there were no effects on viable counts or in the fermentation of different fibre components, but the formation of some bacterial metabolites decreased. This may be due to

    The functional connectivity and structural proximity of elements of the language and motor systems result in frequent co-morbidity post brain injury. Although rehabilitation services are becoming increasingly multidisciplinary and "integrated", treatment for language and motor functions often occurs in isolation. Thus, behavioural therapies which promote neural reorganisation do not reflect the high intersystem connectivity of the neurologically intact brain. As such, there is a pressing need for rehabilitation tools which better reflect and target the impaired cognitive networks. The objective of this research is to develop a combined high dosage therapy tool for language and motor rehabilitation. The rehabilitation therapy tool developed, MaLT (Motor and Language Therapy), comprises a suite of computer games targeting both language and motor therapy that use the Kinect sensor as an interaction device. The games developed are intended for use in the home environment over prolonged periods of time. In order to track patients' engagement with the games and their rehabilitation progress, the game records patient performance data for the therapist to interrogate. MaLT incorporates Kinect-based games, a database of objects and language parameters, and a reporting tool for therapists. Games have been developed that target four major language therapy tasks involving single word comprehension, initial phoneme identification, rhyme identification and a naming task. These tasks have 8 levels each increasing in difficulty. A database of 750 objects is used to programmatically generate appropriate questions for the game, providing both targeted therapy and unique gameplay every time. The design of the games has been informed by therapists and by discussions with a Public Patient Involvement (PPI) group. Pilot MaLT trials have been conducted with three stroke survivors for the duration of 6 to 8 weeks. Patients' performance is monitored through MaLT's reporting facility

    Chronic Helicobacter pylori-stimulated immune reactions determine the pathogenesis of gastric mucosa-associated lymphoid tissue (MALT) lymphoma. We aimed to explore the genetic predisposition to this lymphoma and its clinical implication. A total of 68 patients and 140 unrelated controls were genotyped for 84 single-nucleotide polymorphisms in genes encoding cytokines, chemokines and related receptors that play important roles in T cell-mediated gastrointestinal immunity. Five genotypes in IL-22, namely CC at rs1179246, CC at rs2227485, AA at rs4913428, AA at rs1026788 and TT at rs7314777, were associated with disease susceptibility. The former four genotypes resided in the same linkage disequilibrium block (r 2 =0.99) that conferred an approximately threefold higher risk. In vitro experiments demonstrated that co-culturing peripheral mononuclear cells or CD4 + T cells with H. pylori stimulated the secretion of interleukin-22 (IL-22), and that IL-22 induced the expression of antimicrobial proteins, RegIIIα and lipocalin-2, in gastric epithelial cells. Furthermore, patients with gastric tissue expressing IL-22 were more likely to respond to H. pylori eradication (14/22 vs 4/19, P<0.006). We conclude that susceptibility of gastric MALT lymphoma is influenced by genetic polymorphisms in IL-22, the product of which is involved in mucosal immunity against H. pylori and associated with tumor response to H. pylori eradication

    Our study showed that sorghum and millet followed a similar pattern of changes when they were malted under similar conditions. When the malt from these cereals was mashed, both cereal types produced wide spectra of substrates (sugars and amino acids) that are required for yeast fermentation when malted at either lower or higher temperatures. At the germination temperatures of 20, 25, and 30 °C used in malting both cereal types, production of reducing sugars and that of free amino nitrogen (FAN) were similar. This is an important quality attribute for both cereals because it implies that variation in temperature during the malting of sorghum and millet, especially when malting temperature is difficult to control, and also reflecting temperature variations, experienced in different countries, will not have an adverse effect on the production and release of amino acids and sugars required by yeast during fermentation. Such consistency in the availability of yeast food (substrates) for metabolism during fermentation when sorghum and millet are malted at various temperatures is likely to reduce processing issues when their malts are used for brewing. Although sorghum has gained wide application in the brewing industry, and has been used extensively in brewing gluten-free beer on industrial scale, this is not the case with millet. The work described here provides novel information regarding the potential of millet for brewing. When both cereals were malted, the results obtained for millet in this study followed patterns similar to those of sorghum. This suggests that millet, in terms of sugars and amino acids, can play a role similar to that of sorghum in the brewing industry. This further suggests that millet, like sorghum, would be a good raw material for brewing gluten-free beer. Inclusion of millet as a brewing raw material will increase the availability of suitable materials (raw material sustainability) for use in the production of gluten-free beer, beverages, and

    The gastric lesion is a common source of complaints to Orientals, however, evaluation of gastric symptoms and laboratory examination offer little specific aid in the diagnosis of gastric diseases. Thus roentgenography of gastrointestinal tract is one of the most reliable method for detail diagnosis. On double contract study of stomach, gastric filling defect is mostly caused by malignant gastric cancer, however, other benign lesions can cause similar pictures which can be successfully treated by surgery. 66 cases of benign causes of gastric filling defect were analyzed at this point of view, which was verified pathologically by endoscope or surgery during recent 7 years in Yensei University College of Medicine, Severance Hospital. The characteristic radiological picture of each disease was discussed for precise radiologic diagnosis. 1. Of total 66 cases, there were 52 cases of benign gastric tumor 10 cases of gastric varices, 5 cases of gastric bezoar, 5 cases of corrosive gastritis, 3 cases of granulomatous disease and one case of gastric hematoma. 2. The most frequent causes of benign tumors were adenomatous polyp (35/42) and the next was leiomyoma (4/42). Others were one of case of carcinoid, neurofibroma and cyst. 3. Characteristic of benign adenomatous polyp were relatively small in size, smooth surface and were observed that large size, benign polyp was frequently type IV lesion with a stalk. 4. Submucosal tumors such as leiomyoma needed differential diagnosis with polypoid malignant cancer. However, the characteristic points of differentiation was well circumscribed smooth margined filling defect without definite mucosal destruction on surface. 5. Gastric varices showed multiple lobulated filling defected especially on gastric fundus that changed its size and shape by respiration and posture of patients.

  4. Spatial Complementarity and the Coexistence of Species

    Coexistence of apparently similar species remains an enduring paradox in ecology. Spatial structure has been predicted to enable coexistence even when population-level models predict competitive exclusion if it causes each species to limit its own population more than that of its competitor. Nevertheless, existing hypotheses conflict with regard to whether clustering favours or precludes coexistence. The spatial segregation hypothesis predicts that in clustered populations the frequency of intra-specific interactions will be increased, causing each species to be self-limiting. Alternatively, individuals of the same species might compete over greater distances, known as heteromyopia, breaking down clusters and opening space for a second species to invade. In this study we create an individual-based model in homogeneous two-dimensional space for two putative sessile species differing only in their demographic rates and the range and strength of their competitive interactions. We fully characterise the parameter space within which coexistence occurs beyond population-level predictions, thereby revealing a region of coexistence generated by a previously-unrecognised process which we term the triadic mechanism. Here coexistence occurs due to the ability of a second generation of offspring of the rarer species to escape competition from their ancestors. We diagnose the conditions under which each of three spatial coexistence mechanisms operates and their characteristic spatial signatures. Deriving insights from a novel metric — ecological pressure — we demonstrate that coexistence is not solely determined by features of the numerically-dominant species. This results in a common framework for predicting, given any pair of species and knowledge of the relevant parameters, whether they will coexist, the mechanism by which they will do so, and the resultant spatial pattern of the community. Spatial coexistence arises from complementary combinations of traits in each

    Sorghum types suitable for brewing and bioethanol production are required. The effect of sorghum type (white non-tannin versus white type II tannin) on free amino nitrogen (FAN) production from sorghum grain and malt using exogenous protease enzymes was investigated over extended incubation at moderate temperature (45 °C). With grain in the absence of exogenous proteases, white non-tannin sorghum produced substantially higher levels of FAN than white type II tannin sorghum, due to the tannins in the latter. Incubating sorghum grain with neutral proteinase and amino-peptidase in combination improved FAN production. The two sorghum types produced similar FAN levels when malted and incubated in the absence of the exogenous proteases. When both sorghums were malted and incubated with neutral proteinase alone substantially more FAN yield (124-126 mg 100 g(-1)) occurred than with grains (61-84 mg 100 g(-1)). The combination of amino-peptidase and proteinase did not improve FAN further. Neither, did malting influence wort free amino acid profile. Group B amino acids constituted the highest percentage (42-47%). With grain, white non-tannin sorghum plus proteinase and amino-peptidase yields the highest FAN, with malt both white non-tannin and white type II tannin sorghums plus proteinase yield the highest FAN. © 2014 Society of Chemical Industry.

    Weight loss following gastroplasty had no correlation with gastric emptying rate. Patients who showed transient prolongation of gastric emptying returned to normal one year later and showed no significant difference in weight loss from those who did not have temporary delayed gastric emptying. Perhaps gatroplasty (at least temporarily) reduces the gastric volume producing early satiation without affecting the gastric emptying rate as tested by a small volume radiolabelled test meal. Longer follow-up is indicated to see if delayed weight gain occurs because of gastric pouch stretching and if this has any correlation with gastric emptying rate. (Author)

    Two of the most common species of toxin-producing Fusarium contaminating small cereal grains are Fusarium graminearum and F. poae; with both elaborating diverse toxins, especially deoxynivalenol (DON) and nivalenol (NIV), respectively. The objective of our work during the 2012–2014 growing seasons was to screen crops for the most commonly isolated Fusarium species and to quantify DON and NIV toxins in natural malting-barley samples from different producing areas of Argentina. We identified 1180 Fusarium isolates in the 119 samples analyzed, with 51.2% being F. graminearum, 26.2% F. poae and 22.6% other species. We found high concentrations of mycotoxins, at maximum values of 12 μg/g of DON and 7.71 μg/g of NIV. Of the samples, 23% exhibited DON at an average of 2.36 μg/g, with 44% exceeding the maximum limits (average of 5.24 μg/g); 29% contained NIV at an average of 2.36 μg/g; 7% contained both DON and NIV; and 55% were without DON or NIV. Finally, we report the mycotoxin contamination of the grain samples produced by F. graminearum and F. poae, those being the most frequent Fusarium species present. We identified the main Fusarium species affecting natural malting-barley grains in Argentina and documented the presence of many samples with elevated concentrations of DON and NIV. To our knowledge, the investigation reported here was the first to quantify the contamination by Fusarium and its toxins in natural samples of malting barley in Argentina. PMID:29439459

    Full Text Available This essay examines Rainer Maria Rilke's The Notebooks of Malte Laurids Brigge (1910 as one corner in a triangle of reciprocal influence and affinity in early twentieth-century modernity consisting of Rilke, the sociologist Georg Simmel, and the art theorist Wilhelm Worringer. In the notes, this essay documents the biographical relations among the three, but in its text it demonstrates through textual analysis how Rilke's descriptions of Malte in Paris enact Simmel's categories of psychological response for man in the metropolis, as delineated in his essay "The Metropolis and Mental Life"(1903. Rilke's descriptions of Malte's attempts to overcome his fears of the metropolis coincide then with Worringer's thesis in his Abstraction and Empathy (1908 on the psychological origins of abstract art and Joseph Frank's later elaboration of that thesis into an aesthetics of spatial form.

  13. Effects of nitrogen application rate on dry matter redistribution, grain yield, nitrogen use efficiency and photosynthesis in malting barley

    2012-01-01

    The harmonious combination of malting barley yield, quality and nitrogen (N) use-efficiency under nitrogen (N) rates applications was greatly conducive to production in China. The malting barley cultivar Supi 3 was planted during the growing seasons 2005 and 2006 at two contrasting sites in China....... Five nitrogen (N) application rates (0, 75, 150, 225 and 300 kg ha−1) were applied for research of effects of N rates application on grain yield, protein content and N use-efficiency. At both sites and in both years, grain yield increased with increasing N application rates up to 225 kg N ha−1...... with a quadrant model, the optimum N application rates for high grain yield with high nitrogen use-efficiency in malting barley could be indicated. So, the higher yields could be mainly ascribed to the higher accumulation of photoassimilates between anthesis and maturity. In order to achieve high grain yield...

O objetivo deste relato é descrever os aspectos clínicos e anatomopatológicos da Meningoencefalite Necrotizante (MEN em um cão Maltês. A doença tem um caráter necrótico único e está relacionada intimamente à Encefalite do Cão Pug (ECP devido a suas semelhanças, bem como à Leucoencefalite Necrotizante (LEN. Embora o primeiro relato de caso de ECP tenha mais de 15 anos e o primeiro relato de caso de MEN em Maltês tenha 11 anos, há muito a ser revelado sobre a etiologia e os mecanismos imunopatológicos da doença. Neste trabalho, relata-se o caso de um cão Maltês com sinais que foram compatíveis com a MEN. Foram detectadas nas imagens macroscópicas, cavitação cerebral, e na microscopia, perda de células do parênquima em certas regiões do córtex cerebral. A partir dessas descobertas descreve-se o primeiro caso de MEN em cão Maltês no Brasil.The Necrotizing Meningoencephalitis (NME is an encephalopathy caused by an inflammatory dysfunction with necrotic characterization. The aim of this report is to describe the anatomopathological features of the NME in a Maltese dog. The disease has a unique necrotic pattern and is closely related to Pug Dog Encephalitis (PDE because of their similarity as well as to Necrotizing Leukoencephalitis (NLE. Although the first PDE report has more than 15 years and the first Maltese NME report has 11 years there is a lot to be unveiled about the etiologic and the immunopathologic mechanisms of the disease. Here we report one case of a Maltese dog with signs that were compatible with NME. The gross morphology pictures with the cerebral cavitation and the histological loss of parenchymal cells in some regions of the cerebral cortex were detected. Based on these findings, we describe the first case of NME in Maltese dog in Brazil.

  16. Gastric-emptying tests

    Mechanisms regulating gastric emptying have been characterized through many decades of experimental work. Both central and peripheral mechanisms are important. Central mechanisms are related to the center of vomiting and are probably influenced by psychologic and emotional factors. Peripheral mechanisms are located at both sides of the pylorus. Gastric mechanisms are stimulatory and are triggered mainly by distention of the stomach, although hormonal mechanisms may also participate (gastrin). However, with complex, nutrient-containing meals, the intragastric volume is not the primary determinant of gastric emptying. Inhibitory mechanisms of the gut are more important. The key factors are the pH, osmolality, and nutrient content of the chyme being emptied into the duodenum. Osmotic and pH-sensitive receptors are thought to reside in the duodenum. On the other hand, receptors triggered by nutrients extend much more distally into the duodenum and are sensitive to nutrient composition and load. Protein, carbohydrates, and lipids all inhibit gastric emptying, although the lipids are probably the most potent inhibitors. If the duodenal load or the characteristics of the emptying material are not adequate, inhibitory mechanisms will reduce gastric emptying at the expense of expanding the intragastric volume. It is therefore not possible to dissociate postprandial gastric emptying from postprandial gastric secretion

    Shape coexistence is one of the important nuclear phenomenon which appears throughout the periodic chart from light mass nuclei to superheavy nuclei. The evolution of ground-state shapes in an isotopic or isotonic chain is governed by changes of the shell structure of single-nucleon orbitals. In recent past, evolution of shell structure guiding shape coexistence, has been observed in the N = 20 and N = 28 isotones around proton drip line. In this paper we have investigated shape coexistence phenomenon for N = 28 isotones in the vicinity of proton drip line using Relativistic Mean Field plus BCS approach

    Hejazi, Sara Najdi; Orsat, Valérie

    2016-04-01

    Finger millet (Eleusine coracana) is a nutritious, gluten-free, and drought resistant cereal containing high amounts of protein, carbohydrate, and minerals. However, bio-availability of these nutrients is restricted due to the presence of an excessive level of anti-nutrient components, mainly phytic acid, tannin, and oxalate. It has been shown that a well-designed malting/germination process can significantly reduce these anti-nutrients and consequently enhance the nutrient availability. In the present study, the effects of two important germination factors, duration and temperature, on the enhancement of in-vitro protein digestibility of finger millet were thoroughly investigated and optimized. Based on a central composite design, the grains were germinated for 24, 36, and 48 h at 22, 26, and 30 °C. For all factor combinations, protein, peptide, phytic acid, tannin, and oxalate contents were evaluated and digestibility was assessed. It was shown that during the malting/germinating process, both temperature and duration factors significantly influenced the investigated quantities. Germination of finger millet for 48 h at 30 °C increased protein digestibility from 74 % (for native grain) up to 91 %. Besides, it notably decreased phytic acid, tannin, and oxalate contents by 45 %, 46 %, and 29 %, respectively. Linear correlations between protein digestibility and these anti-nutrients were observed.

Currently, a multi-nuclide AMS ({sup 10}Be, {sup 14}C, {sup 26}Al, {sup 36}Cl, {sup 129}I) system is available and shows good performance in both precision and sensitivity, and the accelerator serves for PIXE, NRA, ERDA/RBS measurements as well. The total operation time of the accelerator has been over 95,000 hours since the start of MALT, 20 years ago. After the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident, many projects related to {sup 129}I have been conducted. The retrospective reconstruction of the {sup 131}I distribution at the accident from {sup 129}I is one of the most important missions for dose evaluation of the residents. The accident-derived {sup 129}I is also quite useful as a tracer for the general iodine dynamics in the environment. As a new tool for environmental assessment related to nuclear activity, including the global fallout from past atmospheric nuclear bomb testing, effects from the spent fuel reprocessing plant, and nuclear accidents such as Chernobyl and FDNPP, a {sup 236}U-AMS system is now under development.

The optimum formula was galanga, garlic, long pepper, licorice, and black pepper at the ratio of 0.5:8:1:4:1,respectively. Previously, waste paddy has been used directly as a renewable resource for fuel ethanol production using solidstate fermentation (SSF with Loog-pang. In this study, hydrolyzed malted rice starch was used as the sole nutrient source insubmerged fermentation (SmF to enhance the process yield. The maximum ethanol productivity (4.08 g/kg waste paddy h-1and the highest ethanol concentration (149±7.0 g/kg waste paddy were obtained after 48 hrs of incubation. The resultsindicated that starch saccharification provided a higher ethanol yield (48.38 g/100g sugar consumed than SSF. In addition,the efficiency of ethanol fermentation was 67% which is similar to that of the malted rice made from normal paddy (68%.This result suggests that waste paddy could be used as an alternative raw material for ethanol production.

    Gastric varices that arise secondary to the splenic vein occlusion can result in gastrointestinal hemorrhaging. Endoscopic color Doppler ultrasonography (ECDUS) was performed in 16 patients with gastric varices secondary to splenic vein occlusion. This study retrospectively evaluated the role of ECDUS in the diagnosis of gastric varices secondary to splenic vein occlusion. Thirteen patients had co-existing pancreatic diseases: 8 with chronic pancreatitis, 4 with cancer of the pancreatic body or tail and 1 with severe acute pancreatitis. Of the remaining 3 patients, 1 had myeloproliferative disease, 1 had advanced gastric cancer, and the third had splenic vein occlusion due to an obscure cause. The endoscopic findings of gastric varices were: variceal form (F) classified as enlarged tortuous (F2) in 12 cases and large, coil-shaped (F3) in 4 cases, and positive for erosion or red color sign of the variceal surface in 4 cases and negative in 12 cases. ECDUS color flow images of gastric variceal flow clearly depicted a round fundal region at the center, with varices expanding to the curvatura ventriculi major of the gastric body in all 16 cases. The velocities of F3 type gastric varices were significantly higher than those of the F2 type. The wall thickness of varices positive for erosion or red color sign was significantly less than the negative cases. I conclude that ECDUS color flow images of gastric variceal flow depicted specific findings of gastric varices secondary to splenic vein occlusion at the round fundal region at the center, with varices expanding to the curvatura ventriculi major of the gastric body.

    The Helicobacter heilmannii sensu lato (H. heilmannii s.l.) group consists of long, spiral-shaped bacteria naturally colonizing the stomach of animals. Moreover, bacteria belonging to this group have been observed in 0.2-6% of human gastric biopsy specimens, and associations have been made with the development of chronic gastritis, peptic ulceration, and gastric MALT lymphoma in humans. To gain insight into the prevalence of H. heilmannii s.l. infections in patients suffering from gastric disease in China, H. heilmannii s.l. species-specific PCRs were performed on DNA extracts from rapid urease test (RUT)-positive gastric biopsies from 1517 patients followed by nucleotide sequencing. At the same time, Helicobacter pylori cultivation and specific PCR was performed to assess H. pylori infection in these patients. In total, H. heilmannii s.l. infection was detected in 11.87% (178/1499) of H. pylori-positive patients. The prevalence of H. suis, H. felis, H. bizzozeronii, H. heilmannii sensu stricto (s.s.), and H. salomonis in the patients was 6.94%, 2.20%, 0.13%, 0.07%, and 2.54%, respectively. Results revealed that all patients with H. heilmannii s.l. infection were co-infected with H. pylori, and some patients were co-infected with more than two different Helicobacter species. Helicobacter heilmannii s.l. infections are fairly common in Chinese patients. This should be kept in mind when diagnosing the cause of gastric pathologies in patients. Helicobacter suis was shown to be by far the most prevalent H. heilmannii s.l.species. © 2014 John Wiley & Sons Ltd.

    Full Text Available Gastric carcinoma is extremely rare in children representing only 0.05% of all gastrointestinal malignancies. Here, we report the first pediatric case of gastric cancer presenting with gastric outlet obstruction. Upper endoscopy revealed a markedly thickened antral mucosa occluding the pylorus and a clean base ulcer 1.5 cm × 2 cm at the lesser curvature of the stomach. The narrowed antrum and pylorus underwent balloon dilation, and biopsy from the antrum showed evidence of Helicobacter pylori gastritis. The biopsy taken from the edge of the gastric ulcer demonstrated signet-ring-cell type infiltrate consistent with gastric adenocarcinoma. At laparotomy, there were metastases to the liver, head of pancreas, and mesenteric lymph nodes. Therefore, the gastric carcinoma was deemed unresectable. The patient died few months after initiation of chemotherapy due to advanced malignancy. In conclusion, this case report underscores the possibility of gastric adenocarcinoma occurring in children and presenting with gastric outlet obstruction.

The most common variant of PRL is the mucosa-associated lymphoid tissue (MALT) type. To date, no study has been able to recommend an optimal treatment algorithm for this rare disease. The aim of our study was to review the English literature on primary rectal MALT lymphoma. A review of the English literature was conducted to identify articles describing the MALT variant of PRL. Fifty-one cases were identified. A complete response was achieved in 12 of 19 cases treated with Helicobacter pylori eradication therapy, 5 of 6 with radiation, 2 of 4 cases with chemotherapy, 2 of 4 with endoscopic resection, 6 of 8 cases with surgical resection, and all 8 with combination therapies. Cases failing initial therapies were responsive to various second-line treatments. Two cases spontaneously regressed with observation alone. Complete regression of primary rectal MALT lymphoma was achieved using various therapeutic strategies, although the numbers of different treatment modalities are too small to draw definitive conclusions.

    The problem is that current definitions of early gastric cancer allow the inclusion of regional lymph node metastases. The increasing use of endoscopic submucosal dissection to treat early gastric cancer is a concern because regional lymph nodes are not addressed. The aim of the study was thus to critically evaluate current evidence with regard to tumour-specific factors associated with lymph node metastases in "early gastric cancer" to develop a more precise definition and improve clinical management. A systematic and comprehensive search of major reference databases (MEDLINE, EMBASE, PubMed and the Cochrane Library) was undertaken using a combination of text words "early gastric cancer", "lymph node metastasis", "factors", "endoscopy", "surgery", "lymphadenectomy" "mucosa", "submucosa", "lymphovascular invasion", "differentiated", "undifferentiated" and "ulcer". All available publications that described tumour-related factors associated with lymph node metastases in early gastric cancer were included. The initial search yielded 1494 studies, of which 42 studies were included in the final analysis. Over time, the definition of early gastric cancer has broadened and the indications for endoscopic treatment have widened. The mean frequency of lymph node metastases increased on the basis of depth of infiltration (mucosa 6% vs. submucosa 28%), presence of lymphovascular invasion (absence 9% vs. presence 53%), tumour differentiation (differentiated 13% vs. undifferentiated 34%) and macroscopic type (elevated 13% vs. flat 26%) and tumour diameter (≤2 cm 8% vs. >2 cm 25%). There is a need to re-examine the diagnosis and staging of early gastric cancer to ensure that patients with one or more identifiable risk factor for lymph node metastases are not denied appropriate chemotherapy and surgical resection.

It can be used in existing engines. Biodiesel consists of fatty acid alkyl esters. Conversion of triglycerides to biodiesel fuel is commonly achieved through a series of transesterification reactions involving the reaction of an alkoxy group of an ester (i.e., mono-, di-, or triglyceride) with that of a small alcohol (usually methanol). This reaction is traditionally catalyzed by homogeneous catalysts, such as bases or mineral acids. Basic catalysts have been proved to be much more active than acidic ones. However, due to environmental (waste water) and economic concerns (catalyst separation and product and by-product cleaning), heterogeneous catalysts are much more desirable. In the present study we have evaluated the use of biochar, produced from malt spent rootlets, as a potential basic catalyst, for transesterification of triglycerides using triacetin as a probe molecule. The biochar used in this study was prepared by heating malt spent rootlets in an oxygen-limited environment. It is a carbon rich material, containing 66% C, 22% O, 0.45% Mg, 0.86% Si, 5.7% K, 1.5% Cl, 0.61% Ca, and 2.4% P. Aqueous suspension of this material equilibrates at pH= 10. This is probably due to high K content. Furthermore, it exhibits high specific surface area (SSA= 183 m2g-1). The above described characteristics make this material very promising catalyst for

    Objective: Although radiation therapy is frequently used in the treatment of ocular adnexal lymphoma, it is uncertain whether it is curative, or whether it simply provides local control in a systemic disease. Extranodal marginal zone (mucosa-associated lymphoid tissue [MALT] type) lymphoma, a recently described type of low-grade lymphoma, is often localized at diagnosis and may therefore potentially be curable with local therapy. We analyzed the pathologic and clinical features of 165 cases of ocular adnexal lymphoma to determine the proportion that were MALT lymphomas, and to compare the frequency of primary versus secondary involvement, the frequency of localized disease, and the probability for local and distant recurrences after radiation therapy in MALT lymphoma relative to other lymphomas. Methods: Clinical and pathologic (morphologic and immunophenotypic) findings were reviewed in 165 cases of ocular adnexal lymphoma diagnosed between 1974 and 1994. The lymphomas were classified according to the recently described Revised European-American Lymphoma Classification Scheme which newly incorporated the diagnostic category of extranodal marginal zone (MALT) lymphoma. Staging information was available in 73 primary cases. Radiation was given as either photons (for intraorbital disease) or electrons (for superficial disease). Photon treatment primarily consisted of a wedged pair of anterior plus anterior-oblique fields to a median dose of 39.6 Gy (range 19.8 - 46 Gy) at 1.8 Gy per fraction. Electron treatment consisted of an en face field to a median dose of 30 Gy (range 25.6 - 40 Gy) at 2.5 Gy per fraction. Survival data were analyzed by the Kaplan-Meier actuarial method. P-values for differences between frequencies of lymphoma types and stages were calculated by chi square. Results: In 133 patients with no known prior history of lymphoma (primary cases), MALT lymphoma accounted for 55%, while other cases were follicle center lymphoma (FCL) (22%), low grade

  6. Coexistence of competing stage-structured populations.

    2011-10-05

    This paper analyzes the stability of a coexistence equilibrium point of a model for competition between two stage-structured populations. In this model, for each population, competition for resources may affect any one of the following population parameters: reproduction, juvenile survival, maturation rate, or adult survival. The results show that the competitive strength of a population is affected by (1) the ratio of the population parameter influenced by competition under no resource limitation (maximum compensatory capacity) over the same parameter under a resource limitation due to competition (equilibrium rate) and (2) the ratio of interspecific competition over intraspecific competition; this ratio was previously shown to depend on resource-use overlap. The former ratio, which we define as fitness, can be equalized by adjusting organisms\\' life history strategies, thereby promoting coexistence. We conclude that in addition to niche differentiation among populations, the life history strategies of organisms play an important role in coexistence.

    2012-01-01

    Full Text Available Traditional sorghum beers are produced in several countries of Africa, but variations in the manufacturing process may occur depending on the geographic localization. These beers are very rich in calories, B-group vitamins including thiamine, folic acid, riboflavin and nicotinic acid, and essential amino acids such as lysine. However, the traditional sorghum beer is less attractive than Western beers because of its poorer hygienic quality, organoleptic variations and shorter shelf life. Research into the microbiological and biochemical characteristics of traditional sorghum beers as well as their technologies have been performed and documented in several African countries. This review aims to summarize the production processes and compositional characteristics of African traditional sorghum beers (ikigage, merissa, doro, dolo, pito, amgba and tchoukoutou. It also highlights the major differences between these traditional beers and barley malt beer, consumed worldwide, and suggests adaptations that could be made to improve the production process of traditional sorghum beer.

    The control strategy of temperature and humidity in the beer barley malt drying chamber based on fuzzy logic control was implemented.Expounded in this paper was the selection of parameters for the structure of the regulatory device, as well as the essential design from control rules based on the existing experience. A temperature fuzzy controller was thus constructed using relevantfuzzy logic, and humidity control was achieved by relay, ensured the situation of the humidity to control the temperature. The temperature's fuzzy control and the humidity real-time control were all processed by single chip microcomputer with assembly program. The experimental results showed that the temperature control performance of this fuzzy regulatory system,especially in the ways of working stability and responding speed and so on,was better than normal used PID control. The cost of real-time system was inquite competitive position. It was demonstrated that the system have a promising prospect of extensive application.

    The chemical changes of high-mass star-forming regions provide a potential method for classifying their evolutionary stages and, ultimately, ages. In this study, we search for correlations between molecular abundances and the evolutionary stages of dense molecular clumps associated with high-mass star formation. We use the molecular line maps from Year 1 of the Millimetre Astronomy Legacy Team 90 GHz (MALT90) Survey. The survey mapped several hundred individual star-forming clumps chosen from the ATLASGAL survey to span the complete range of evolution, from prestellar to protostellar to H II regions. The evolutionary stage of each clump is classified using the Spitzer GLIMPSE/MIPSGAL mid-IR surveys. Where possible, we determine the dust temperatures and H{sub 2} column densities for each clump from Herschel/Hi-GAL continuum data. From MALT90 data, we measure the integrated intensities of the N{sub 2}H{sup +}, HCO{sup +}, HCN and HNC (1-0) lines, and derive the column densities and abundances of N{sub 2}H{sup +} and HCO{sup +}. The Herschel dust temperatures increase as a function of the IR-based Spitzer evolutionary classification scheme, with the youngest clumps being the coldest, which gives confidence that this classification method provides a reliable way to assign evolutionary stages to clumps. Both N{sub 2}H{sup +} and HCO{sup +} abundances increase as a function of evolutionary stage, whereas the N{sub 2}H{sup +} (1-0) to HCO{sup +} (1-0) integrated intensity ratios show no discernable trend. The HCN (1-0) to HNC(1-0) integrated intensity ratios show marginal evidence of an increase as the clumps evolve.

    Full Text Available In food industry, especially among the brewers, using of natural ingredients is increasingly growing demand. Beer is one of the most popular beverages in the world with evident positive effects on the overall health condition. It can be used as a base for developing a variety of products with specific physiological activity. Bee pollen is considered to be one of the possible sources of active ingredients for that purpose. Activity of phenolic and flavonoid compounds in bee pollen can contribute to the antioxidant potential of beer. The objective of this study was to examine the influence of different types and content of bee pollen on the antioxidant properties of malt beverages and to compare phenolic and flavonoid profiles. The technological process of malt beverages preparation with addition of bee pollen was also verified. It was found out that all beverages enriched with bee pollen had higher polyphenol, flavonoid content and antioxidant potential than control sample – pure wort. The higher antioxidant activities of all extracts was measured in sample R2 - wort with 0.6% of dry rapeseed pollen and sample R4 - wort with 0.6% of frozen rapeseed pollen. The higher phenolic content than in other samples was measured in sample M4 - wort with 0.6% of frozen poppy pollen and sample M1 - wort with 0.256% of dry poppy pollen. Higher total flavonoid content was found out in sample M2 - wort with 0.6% of dry poppy pollen and M4 - wort with 0.6% of frozen poppy pollen. In conclusion, the most noticeable results of antioxidant activity, phenolic and flavonoid content were achieved in samples with higher 0.6% addition of bee pollen, mostly poppy (Papaver somniferum L. pollen.

    This paper gives conditions under which vertical separation is chosen by some upstream firms, while vertical integration is chosen by others in the equilibrium of a symmetric model. A vertically separating firm trades off fixed contracting costs against the strategic benefit of writing a (two......-part tariff, exclusive dealing) contract with its retailer. Coexistence emerges when more than two vertical Cournot oligopolists supply close substitutes. When vertical integration and separation coexist, welfare could be improved by reducing the number of vertically separating firms. The scope...

    2011-05-10

    Epithelioid haemangioendothelioma (EHE) is a rare tumour of vascular origin, characterised by celular proliferation, endotelial, epitelioid or hystiocitoid. It may develop in any organ, but it is more common in lung and liver. Surgery is the recommended treatment; however, in case of a potentially benign situation, an expectant attitude should be adopted. The case reports a 71-year-old female who underwent a laparotomy for a colonic adenocarcinoma. During surgery, a polypoid lesion in the dependency of the gastric wall was found incidentally, which was removed. Histopathology and immunohistochemical analysis confirmed the diagnosis of EHE. Gastric vascular neoplasms represent about 0.9-3.3% of all gastric tumours. Usually have a good prognosis, but due to the borderline biological behaviour of these tumours, it is important to have a detailed clinical evaluation at follow-up of these patients.

    Host innate immunity can affect the clinical outcomes of Helicobacter pylori infection, including gastritis, gastric ulcer, gastric adenocarcinoma, and MALT lymphoma. Nucleotide binding oligomerization domain (NOD)-1 and -2 are two molecules of innate immunity which are involved in the host defense against H. pylori. This study aimed to evaluate the effect of the expression level of NOD1 and NOD2 on the susceptibility to gastric cancer as well as peptic ulcer in individuals with H. pylori infection. The gene expression levels of these molecules were compared in three groups of non-ulcer dyspepsia (NUD) as a control group (n=52); peptic ulcer disease (PUD), (n=53); and gastric cancer (GC), (n=39). Relative expression levels of NOD1 in patients with GC were higher than those of NUD and PUD (p<0.001 and P<0.001, respectively). Similarly in case of NOD1, PUD group showed higher level of expression than NUD group (p<0.01). However, there was no significant difference between H. pylori -positive and -negative patients in NUD, PUD, or GC groups. Moreover, the expression levels of NOD2 showed no significant difference among NUD, PUD, or GC groups, while among H. pylori-positive patients, it was higher in GC group than NUD  and PUD groups (p<0.05 and p<0.01, respectively). In addition, positive correlation coefficients were attained between NOD1 and NOD2 expressions in patients with NUD (R2 Linear=0.349, p<0.001), PUD (R2 Linear=0.695, p<0.001), and GC (R2 Linear=0.385, p<0.001). Collectively, the results suggest that the chronic activation of NOD1 and NOD2 receptors might play a role in the development of gastric cancer.

    Gastric cancer is among the most common human malignancies and the second leading cause of cancer-related death. The different epidemiologic and histopathology of subtypes of gastric cancer are associated with different genomic patterns. Data suggests that gene expression patterns of proximal, distal gastric cancers-intestinal type, and diffuse/signet cell are well separated. This review summarizes the genetic and epigenetic changes thought to drive gastric cancer and the emerging paradigm of gastric cancer as three unique disease subtypes.

    Gastric rupture after blunt abdominal trauma is a rare injury with few reports in the literature. The purpose of this study was to review our experience with blunt gastric injuries and compare outcomes with small bowel or colon injuries. All patients with hollow viscus perforations after blunt abdominal trauma from 1992 to 2005 at our level I trauma center were reviewed. Of 35,033 blunt trauma admissions, there were 268 (0.7%) patients with a total of 319 perforating hollow viscus injuries, 25 (0.07%) of which were blunt gastric injuries. When compared with the small bowel or colon injuries, the blunt gastric injury group had a higher Injury Severity Score (22 versus 17, P = 0.04), more patients with a chest Abbreviated Injury Score greater than 2 (36% versus 12%, P < 0.01), and a shorter interval from injury to laparotomy (221 versus 366 minutes, P = 0.017). Multivariate analysis identified five independent risk factors for mortality: age older than 55 years, head Abbreviated Injury Score greater than 2, chest Abbreviated Injury Score greater than 2, the presence of hypotension on admission, and Glasgow Coma Scale 8 or less. The results of this study suggest that mortality in patients with blunt hollow viscus injuries can be attributed to concurrent head and chest injuries, but not the specific hollow viscus organ that is injured.

    Gastric neuroendocrine tumours (NETs) are increasingly recognised, and management decisions may be difficult due to an incomplete understanding of aetiology, natural history and optimum therapy. This article presents a current understanding based on recent advances in epidemiology, classification, molecular profiling, and treatment. Relevant medical literature was identified from searches of PubMed and references cited in appropriate articles identified. Selection of articles was based on peer review, journal and relevance. Gastric NETs may be divided into three clinical prognostic groups: type I is associated with autoimmune atrophic gastritis and hypergastrinaemia, type II is associated with Zollinger-Ellison syndrome, and type III lesions are gastrin-independent, have the greatest metastatic potential and poorest prognosis. There has been an increased frequency of gastric NETs reported. Management approaches have evolved in parallel with advances in endoscopic staging and surgery, as well as improved understanding of the biology and natural history of NETs. Gastric NETs present a spectrum of activity from indolent tumours to metastatic malignancy. Treatment decisions for patients must be individualised and are best managed by a multidisciplinary team approach. The current evidence base is limited to small series and efforts to treat patients within clinical networks of expertise are warranted. Copyright © 2012 S. Karger AG, Basel.

To investigate the influence of mastication on gastric emptying and motility, we conducted a randomized trial to compare the effects of mastication on gastric emptying and gastric myoelectrical activity under conditions that excluded the influences of food comminution, taste, and olfaction. A (13)C-acetate breath test with electrogastrography and electrocardiography was performed in 14 healthy men who ingested a test meal with or without chewing gum. Autonomic nerve activity was evaluated by fluctuation analysis of heart rate. Gastric emptying was significantly delayed in the 'ingestion with mastication' group. Gastric myoelectrical activity was significantly suppressed during mastication and increased gradually in the post-mastication phase. A decrease in the high-frequency power of heart rate variability was observed coincidentally with gastric myoelectrical activity suppression. These findings suggest that initial gastric emptying is suppressed by mastication, and that the suppression is caused by mastication-induced inhibition of gastric activity (UMIN Clinical Trial Registration no. UMIN000005351).

    Full Text Available A simple and reliable method for the simultaneous determination of nine phenolic compounds in barley and malted barley was established, using liquid chromatography-diode array detection-electrospray ionization tandem mass spectrometry (HPLC-DAD-ESI-MS/MS. The phenolic compounds can be easily detected with both systems, despite significant differences in sensitivity. Concentrations approximately 180-fold lower could be achieved by mass spectrometry analysis compared to diode array detection, especially for the flavan-3-ols (+-catechin and (−-epicatechin, which have poor absorptivity in the UV region. Malt samples were characterized by higher phenolic content comparing to corresponding barley varieties, revealing a significant increase of the levels of (+-catechin and (−-epicatechin during the malting process. Moreover, the industrial malting is responsible for modification on the phenolic profile from barley to malt, namely on the synthesis or release of sinapinic acid and epicatechin. Accordingly, the selection of the malting parameters, as well as the barley variety plays an important role when considering the quality and antioxidant stability of beer.

    The gastric epithelium is continuously regenerated by gastric stem cells, which give rise to various kinds of daughter cells, including parietal cells, chief cells, surface mucous cells, mucous neck cells, and enteroendocrine cells. The self-renewal and differentiation of gastric stem cells need delicate regulation to maintain the normal physiology of the stomach. Recently, it was hypothesized that cancer stem cells drive the cancer growth and metastasis. In contrast to conventional clonal ev...

    The clinical efficacy displayed by ibrutinib in chronic lymphocytic leukemia (CLL) has been challenged by the frequent emergence of resistant clones. The ibrutinib target, Bruton's tyrosine kinase (BTK), is essential for B-cell receptor signaling, and most resistant cases carry mutations in BTK or PLCG2 , a downstream effector target of BTK. Recent findings show that MI-2, a small molecule inhibitor of the para-caspase MALT1, is effective in preclinical models of another type of BCR pathway-dependent lymphoma. We therefore studied the activity of MI-2 against CLL and ibrutinib-resistant CLL. Treatment of CLL cells in vitro with MI-2 inhibited MALT1 proteolytic activity reduced BCR and NF-κB signaling, inhibited nuclear translocation of RelB and p50, and decreased Bcl-xL levels. MI-2 selectively induced dose and time-dependent apoptosis in CLL cells, sparing normal B lymphocytes. Furthermore, MI-2 abrogated survival signals provided by stromal cells and BCR cross-linking and was effective against CLL cells harboring features associated with poor outcomes, including 17p deletion and unmutated IGHV Notably, MI-2 was effective against CLL cells collected from patients harboring mutations conferring resistance to ibrutinib. Overall, our findings provide a preclinical rationale for the clinical development of MALT1 inhibitors in CLL, in particular for ibrutinib-resistant forms of this disease.

    Malting is a beneficial approach to improve the nutritional value of cereals used in infant preparations. Malted finger millet and amaranth might be considered as potentially appropriate gluten-free alternatives for common wheat-based weaning products, especially in case of those suffering from celiac disease. In this study, the effects of germination temperature and duration on the main nutrients of malted finger millet and amaranth, are evaluated and optimized. Grains were germinated for 24, 36 and 48 h at 22, 26 and 30 °C. In the case of finger millet, germinating for 48 h at 30 °C resulted into 17% increase in protein availability, 10% increase in total energy and 60% reduction in resistant starch (RS). For amaranth, germinating for 48 h at 26 °C was preferable, resulting in 8% increase in protein availability, 11% increase in total energy, 70% reduction in RS and a 10% increase in the linoleic acid.

    To compare clinicopathologic and molecular characteristics of low-grade gastric mucosa-associated lymphoid tissue lymphoma depending on Helicobacter pylori positivity and to find out a predictive factor for unresponsiveness to Helicobacter pylori eradication therapy in Korea. A total of 53 Helicobacter pylori-positive and 13 negative mucosa-associated lymphoid tissue lymphoma patients were enrolled, and tissues from 21 patients were investigated to examine the presence of t(11;18)(q21;q21) with fluorescence in situ hybridization. Clinicopathologic features such as the endoscopic appearance, dominant site of lesion, depth of invasion, clinical stage, and the existence of MALT1 gene rearrangement were compared between these two groups. Fifty-six patients who underwent H. pylori eradication therapy were divided into responder and nonresponder groups. The two groups were analyzed to calculate odds ratios for resistance to the eradication. Helicobacter pylori-negative gastric mucosa-associated lymphoid tissue lymphoma patients averaged a more advanced clinical stage than H. pylori-positive (p = .023) patients. The frequency of t(11;18)/API2-MALT1 did not differ between H. pylori-positive (45.5%) and H. pylori-negative cases (55.6%). Thirty-eight of 51 (74.5%) H. pylori-positive patients achieved complete regression after the eradication, while 2 of 5 (40%) H. pylori-negative patients obtained regression. Presence of lesions in both distal and proximal parts of stomach (p = .041) and bearing of t(11;18)(q21;q21) (p = .007) were predictors for nonresponsiveness for H. pylori eradication. Helicobacter pylori eradication could be performed as a primary therapy regardless of H. pylori status, and assessing t(11;18)/API2-MALT1 would be considered after failure to remission by H. pylori eradication. © 2013 John Wiley & Sons Ltd.

    Gastric polyps are often an incidental finding on upper gastrointestinal endoscopy, with an incidence up to 5%. The majority of gastric polyps are asymptomatic, occurring secondary to inflammation. Prior reviews discussed Helicobacter pylori (H pylori)-associated singular gastric polyposis; however, we present a rare and unusual case of recurrent multiple benign gastric polyposis post H pylori eradication resulting in intermittent gastric outlet obstruction. A 70-year-old independent male, Chinese in ethnicity, with a background of diabetes mellitus, hypertension, and a simple renal cyst presented with a combination of melena, anemia, and intermittent vomiting of partially digested food after meals. Initial gastroscopy was positive for H pylori; thus he was treated with H pylori eradication and proton pump inhibitors. Serial gastroscopy demonstrated multiple sessile gastric antral polyps, the largest measuring 4 cm. Histopathologic examination confirmed a benign hyperplastic lesion. Computed tomography identified a pyloric mass with absent surrounding infiltration or metastasis. A distal gastrectomy was performed, whereby multiple small pyloric polyps were found, the largest prolapsing into the pyloric opening, thus explaining the intermittent nature of gastric outlet obstruction. Such polyps often develop from gastric ulcers and, if left untreated, may undergo neoplasia to form malignant cells. A distal gastrectomy was an effective choice of treatment, taking into account the polyp size, quantity, and potential for malignancy as opposed to an endoscopic approach, which may not guarantee a complete removal of safer margins and depth. Therefore, surgical excision is favorable for multiple large gastric polyps with risk of malignancy.

In the histogram reweighting method, the distributions of density and energy calculated in Grand Canonical Monte Carlo simulations are stored in histograms and analyzed to construct the grand canonical partition function of the system. All thermodynamic properties are calculated from the grand partition function. The results are compared with Wertheim close-quote s renormalization perturbation theory. Deviations between theory and simulation results for the coexistence envelope are near 2% for the lower dipole moment and 10% for the higher dipole moment we studied. copyright 1997 American Institute of Physics

    Full Text Available Utilizing sports and other recreational activities to foster peaceful relations and coexistence is an idea that has gained popularity in recent years, particularly in Israel. The aim of the current research is to fill a gap in the research literature on the subject of coexistence programming. The Mifalot organization conducts a program called “Get to Know Your Neighbor” in which Palestinian, Jordanian, and Israeli youth play soccer together. The program, based mainly on the participants’ love for football, is a series of activities and lessons designed to prepare children to meet and interact with youth from neighboring communities. The study examines the effects of participation in this program on the attitudes of the Palestinians, Jordanians, and Israelis toward each other.

    Despite its decreasing incidence overall, gastric cancer is still a challenging disease. Therapy is based mainly upon surgical resection when the tumour remains localised in the stomach. Conventional chemotherapy may play a role in treating micrometastatic disease and is effective as palliative therapy for recurrent or advanced disease. However, the knowledge of molecular pathways implicated in gastric cancer pathogenesis is still in its infancy and the contribution of molecular biology to the development of new targeted therapies in gastric cancer is far behind other more common cancers such as breast, colon or lung. This review will focus first on the difference of two well defined types of gastric cancer: intestinal and diffuse. A discussion of the cell of origin of gastric cancer with some intriguing data implicating bone marrow derived cells will follow, and a comprehensive review of different genetic alterations detected in gastric cancer, underlining those that may have clinical, therapeutic or prognostic implications.

    Differences in body sizes may create a trade-off between foraging efficiency (foraging gains/costs) and access to resources. Such a trade-off provides a potential mechanism for ecologically similar species to coexist on one resource. We explored this hypothesis for tundra (Cygnus columbianus) and trumpeter swans (Cygnus buccinator), a federally protected species, feeding solely on sago pondweed (Stuckenia pectinata) tubers during fall staging and wintering in northern Utah. Foraging efficiency was higher for tundra swans because this species experienced lower foraging and metabolic costs relative to foraging gains; however, trumpeter swans (a) had longer necks and therefore had access to exclusive resources buried deep in wetland sediments and (b) were more aggressive and could therefore displace tundra swans from lucrative foraging locations. We conclude that body size differentiation is an important feature of coexistence among ecologically similar species feeding on one resource. In situations where resources are limiting and competition for resources is strong, conservation managers will need to consider the trade-off between foraging efficiency and access to resources to ensure ecologically similar species can coexist on a shared resource.

    2015-01-01

    The consequences of global change for the maintenance of species diversity will depend on the sum of each species responses to the environment and on the interactions among them. A wide ecological literature supports that these species-specific responses can arise from factors related to life strategies, evolutionary history and intraspecific variation, and also from environmental variation in space and time. In the light of recent advances from coexistence theory combined with mechanistic explanations of diversity maintenance, we discuss how global change drivers can influence species coexistence. We revise the importance of both competition and facilitation for understanding coexistence in different ecosystems, address the influence of phylogenetic relatedness, functional traits, phenotypic plasticity and intraspecific variability, and discuss lessons learnt from invasion ecology. While most previous studies have focused their efforts on disentangling the mechanisms that maintain the biological diversity in species-rich ecosystems such as tropical forests, grasslands and coral reefs, we argue that much can be learnt from pauci-specific communities where functional variability within each species, together with demographic and stochastic processes becomes key to understand species interactions and eventually community responses to global change.

    The mechanisms that drive species coexistence and community dynamics have long puzzled ecologists. Here, we explain species coexistence, size structure and diversity patterns in a phytoplankton community using a combination of four fundamental factors: organism traits, size-based constraints, hydrology and species competition. Using a ‘microscopic’ Lotka–Volterra competition (MLVC) model (i.e. with explicit recipes to compute its parameters), we provide a mechanistic explanation of species coexistence along a niche axis (i.e. organismic volume). We based our model on empirically measured quantities, minimal ecological assumptions and stochastic processes. In nature, we found aggregated patterns of species biovolume (i.e. clumps) along the volume axis and a peak in species richness. Both patterns were reproduced by the MLVC model. Observed clumps corresponded to niche zones (volumes) where species fitness was highest, or where fitness was equal among competing species. The latter implies the action of equalizing processes, which would suggest emergent neutrality as a plausible mechanism to explain community patterns. PMID:21177680

    Gastric volvulus, defined as an abnormal rotation of stomach, may be idiopathic or secondary to abnormal fixation of intraperitoneal visceral ligaments. Wandering spleen is a movable spleen resulting from absence or underdevelopment of the splenic supporting ligaments that suspend the spleen to its normal position in the left part of the supramesocolic compartment of the abdomen. Wandering spleen increases the risk of splenic torsion. Both gastric volvulus and splenic torsion are potentially life-threatening if not urgently managed with surgery. Prompt and accurate diagnosis based on multidetector computed tomography (MDCT) is crucial to prevent unforeseen complications. Gastric volvulus and coexistent torsion of wandering spleen is a very rare condition. Herein, we described a case of gastric volvulus associated with wandering spleen and intestinal non-rotation in a 15-year-old girl focusing on MDCT findings

    Full Text Available The aim of the work was to evaluate the effect of addition of humidity absorbent (malt sprouts and chemical conservation additive on fermentation process quality of brewer grains’ silage. Chemical conservation additive was based on formic acid, propionic acid, benzoic acid and ammonium formate content. In a model experiment the fresh brewer grains were used. A dry matter (DM content of brewer grains was 187.4 g / kg. Six treatments with three repetitions per treatment were prepared. The treatments A1, A2 and A3 were not supplied by humidity absorbent. Treatment A1 was a control treatment without any additive. The treatments A2 and A3 were supplied by chemical conservation additive in a dose of 3 L per tonne and 6 L per tonne, respectively. The treatments B1, B2 and B3 were supplied by malt sprouts to reach DM content of conserved matter on level 320–350 g / kg. Moreover the treatments B2 and B3 were supplied by chemical additive with its dose 3 and 6 L per tonne. Model silages were evaluated after 8 months of conservation at average laboratory temperature 26–28  °C, from each treatment were the final laboratory samples taken and analyzed. During conservation of treatments B1, B2 and B3 were no drain recognized. From A1 treatment drained 1300 ml of waste fluid that is 145 L per tonne of conserved matter. That was significant (P < 0.01 the malt sprouts addition support the lactic acid production and eliminate acetic acid production. There was no propionic acid or butyric acid detected in silages with malt sprouts event in these silages were analyzed higher (P < 0.01 concentration of ammoniac. Chemical additive supplementation improved (P < 0.01 the pH value and water leach acidity. The results show the malt sprout addition eliminates waste fluid drain and improves fermentation process. The higher concentration of chemical additive (6 l / t inhibited the fermentation process in our model experiment.

    In recent years, due to the negative impact of toxigenic mycobiota and of the accumulation of their secondary metabolites in malting barley grains, monitoring the evolution of fungal communities in a certain cultivation area as well as detecting the different mycotoxins present in the raw material prior to malting and brewing processes have become increasingly important. In this study, a survey was carried out on malting barley samples collected after their harvest in the Umbria region (central Italy). Samples were analyzed to determine the composition of the fungal community, to identify the isolated Fusarium species, to quantify fungal secondary metabolites in the grains and to characterize the in vitro mycotoxigenic profile of a subset of the isolated Fusarium strains. The fungal community of barley grains was mainly composed of microorganisms belonging to the genus Alternaria (77%), followed by those belonging to the genus Fusarium (27%). The Fusarium head blight (FHB) complex was represented by nine species with the predominance of Fusarium poae (37%), followed by Fusarium avenaceum (23%), Fusarium graminearum (22%) and Fusarium tricinctum (7%). Secondary metabolites biosynthesized by Alternaria and Fusarium species were present in the analyzed grains. Among those biosynthesized by Fusarium species, nivalenol and enniatins were the most prevalent ones. Type A trichothecenes (T-2 and HT-2 toxins) as well as beauvericin were also present with a high incidence. Conversely, the number of samples contaminated with deoxynivalenol was low. Conjugated forms, such as deoxynivalenol-3-glucoside and HT-2-glucoside, were detected for the first time in malting barley grains cultivated in the surveyed area. In addition, strains of F. avenaceum and F. tricinctum showed the ability to biosynthesize in vitro high concentrations of enniatins. The analysis of fungal secondary metabolites, both in the grains and in vitro, revealed also the presence of other compounds, for which

    Gastric emptying of a semiliquid test meal with 5 MBq /sup 99m/Tc-sulfur colloid as a marker was measured in 97 chronic dyspeptic patients and 16 healthy subjects. A comparison of half emptying time between both showed that chronic dyspeptic patients empty semiliquid meal at a significantly (p < 0.005) slower rate (at 70 +- 33 min) than healthy controls (at 52 x 20 min). The studies indicate that gastric stasis in chronic dyspepsia is not caused by inflammatory changes in gastric or duodenal mucosa nor by different gastric acid secretion. The presence of stasis cannot be predicted sufficiently by anamnestic complaints or endoscopic findings. (author)

    Gastric Schwannoma is a rare benign intramural tumor arising from the stomach, and it accounts for only 0.1% of all the different kinds of gastric neoplasms, and it's less than 4% of all the benign gastric tumors. This tumor is very difficult to differentiate from the other mesenchymal tumors by the clinical, endoscopic and radiologic findings. In this study, we demonstrate the appearance of this tumor on endoscopic ultrasound and contrast-enhanced abdomen CT. We also show the histopathologic findings of a surgically confirmed gastric Schwannoma that was located in the proper muscle layer

Materials and Methods. Esophageal and gastric cancer cases, who underwent surgery between January 1, 2012, and December 31, 2013, were examined. Pathology reports of the patients and presence of Helicobacter pylori (HP were recorded. Surveys were filled by face to face meeting or telephone call. Control group was created with randomly selected individuals without any cancer diagnosis having age, gender, and socioeconomic characteristics similar to patient group. All data were analyzed using SAS.9.3 statistical programme. Results. Compared with the control group, herby cheese consumption (a component of eating habits and smoking were significantly higher in the patient group (P<0.001. Tandoor exposure is compared in terms of female gender, and significant difference was found between the groups (P=0.0013. As a result of the analysis with logistic regression more than 150 gr of herby cheese consumption per day was found to increase the cancer risk (odds ratio 1.017; 95% CI: 1.012–1.022. Conclusion. A high consumption of herby cheese, cooking bread on tandoor, and heavy smoking were seen to be important risk factors for esophageal and gastric cancers.

    Full Text Available The aim of this case-control study, conducted in Serbia during the period 1998-2000, was to investigate whether diet was associated with the development of gastric cancer. The case group consisted of 131 patients with histologically confirmed gastric cancer, and the control group of 131 patients with orthopedics diseases and injuries. Cases and controls were individually matched by age (±± 2 years, gender, and place of residence. On the basis of multivariate logistic regression analysis, following factors were found as independent risk factors for gastric cancer: more frequent consumption of high-fat milk [Odds ratio (OR =1.45, 95% confidence interval (CI = 0.99-2.16]; mutton, lamb and/or calf meat (OR = 2.46, 95% CI = 1.11-5.47, sugar (OR = 2.13, 95% CI = 1.43-3.18, semi-white bread (OR = 2.09, 95% CI = 1.25-3.50, and salting food (OR = 5.72, 95% CI = 2.63-12.42. Factors found as protective were: more frequent consumption of margarine (OR = 0.41, 95% CI = 0.25-0.69, „other“ cheeses (OR = 0.47, 95% CI = 0.29 - 0.77, and fish (OR = 0.39, 95% CI = 0.19-0.76.

    Full Text Available A bezoar is an intraluminal mass formed by the accumulation of undigested material in the gastrointestinal tract. Trichobezoar is a rare condition seen almost exclusively in young women with trichotillomania and trichotillophagia. When not recognized, the trichobezoar continues to grow, which increases the risk of severe complications such as gastric ulceration and even perforation. Formation of a gallstone within the trichobezoar (tricholithobezoar is an event that has not yet been described. We report the case of a 22-year-old woman admitted to the emergency room with signals and symptoms of an epigastric mass and perforative acute abdomen. Radiological study revealed bilateral pneumoperitoneum. Personal history revealed depressive syndrome, trichotillomania and trichophagia. With a diagnosis of visceral perforation, an urgent exploratory laparotomy was performed. This confirmed the diagnosis of gastric perforation due to a large trichobezoar with the formation of a gastrolith that was removed by anterior gastrotomy. Biochemical study of the gastric stone revealed that it was composed of bile salts. There were no complications. The patient was discharged on the 5th postoperative day and was referred for psychiatric treatment.

    Full Text Available Barley ( L. is an economically important model plant for genetics research. Barley is currently served by an increasingly comprehensive set of tools for genetic analysis that have recently been augmented by high-density genetic linkage maps built with gene-based single nucleotide polymorphisms (SNPs. These SNP-based maps need to be aligned with earlier generation maps, which were used for quantitative trait locus (QTL detection, by integrating multiple types of markers into a single map. A 2383 locus linkage map was developed using the Oregon Wolfe Barley (OWB Mapping Population to allow such alignments. The map is based on 1472 SNP, 722 DArT, and 189 prior markers which include morphological, simple sequence repeat (SSR, Restriction Fragment Length Polymorphism (RFLP, and sequence tagged site (STS loci. This new OWB map forms, therefore, a useful bridge between high-density SNP-only maps and prior QTL reports. The application of this bridge concept is shown using malting-quality QTLs from multiple mapping populations, as reported in the literature. This is the first step toward developing a Barley QTL Community Curation workbook for all types of QTLs and maps, on the GrainGenes website. The OWB-related resources are available at OWB Data and GrainGenes Tools (OWB-DGGT (.

    Full Text Available One of the most important biological substances consumed in insufficient quantity is fibre that is often deficient in the diet. In general, dietary fibre is edible part of plants, or similar carbohydrates, that are resistant to digestion and absorption in the small intestine. Nowadays, there are many sources of fibre available for bakery industry, whether through addition of non-traditional bread cereals or through isolated form as additives. Except to supposed increase the nutritional value of bakery products with added fiber and raw materials containing fiber is necessary to think about their technological quality and rheological properties of dough. The aim of this experimental work was to investigate the effect of the addition of selected polysaccharides (inulin, Potex - potato fiber and non-bakery crops (naked barley, malt containing significant polysaccharides used in the mixture with wheat flour type T-650 in different ratios on the basis of farinographic evaluations. Based on the results of rheological measurements we found out that quality of dough was deteriorating proportionally to the amount of used additives. On the other hand, positively could be considered the increase of water absorption with addition of Potex and naked barley.

    One of the purposes to employ modern technologies in agricultural and food industry is to increase the efficiency and automation of production processes, which helps improve productive effectiveness of business enterprises, thus making them more competitive. Nowadays, a challenge presents itself for this branch of economy, to produce agricultural and food products characterized by the best parameters in terms of quality, while maintaining optimum production and distribution costs of the processed biological material. Thus, several scientific centers seek to devise new and improved methods and technologies in this field, which will allow to meet the expectations. A new solution, under constant development, is to employ the so-called machine vision which is to replace human work in both quality and quantity evaluation processes. An indisputable advantage of employing the method is keeping the evaluation unbiased while improving its rate and, what is important, eliminating the fatigue factor of the expert. This paper elaborates on the topic of quality evaluation by marking the contamination in malting barley grains using computer image analysis and selected methods of artificial intelligence [4-5].

    T-2 and HT-2 toxins are two of the most toxic members of type-A trichothecenes, produced by a number of Fusarium species. The occurrence of these mycotoxins was studied in barley samples during a survey carried out in the 2011-2014 growing seasons in climatically different regions in Italy. The percentage of samples found positive ranges from 22% to 53%, with values included between 26 and 787 μg/kg. The percentage of samples with a T-2 and HT-2 content above the EU indicative levels for barley of 200 μg/kg ranges from 2% to 19.6% in the 2011-2014 period. The fungal species responsible for the production of these toxins in 100% of positive samples has been identified as Fusarium langsethiae, a well-known producer of T-2 and HT-2 toxins. A positive correlation between the amount of F. langsethiae DNA and of the sum of T-2 and HT-2 toxins was found. This is the first report on the occurrence of F. langsethiae-and of its toxic metabolites T-2 and HT-2-in malting barley grown in Italy.

    Our objective is to estimate the relative price elasticity of demand for malt liquor beer (MLB), regular beer, hard liquor, and a combined group of all other alcoholic beverages. Three hundred and twenty-nine alcohol consumers (mostly male) in South-Central Los Angeles answered a series of questions pertaining to expected consumption responses to hypothetical price increases. We found that based on a 10% price increase, the mean price elasticity of demand (% change in quantity demanded / % change in price) was -0.79 for MLB drinkers, -1.14 for regular beer drinkers, -1.11 for hard liquor drinkers, and -1.69 for the combined group of all other drinkers. Logistic regression analysis revealed that the personal characteristics significantly related to being a MLB drinker were older age, not working, being homeless, and a daily drinker. Daily (or nearly daily) drinkers were more likely to be married, earning lower incomes, and hard liquor drinkers. This study is the first to investigate the price elasticity of demand for MLB drinkers and other heavy alcohol consumers in poor urban neighborhoods of the US. Future research can use the methods from this pilot study to more rigorously examine and compare the price sensitivity among heavy drinking groups.

    Functional foods targeting the improvement of gastrointestinal health are widely recognized; of these, dairy-based probiotics are the most popular. Thus, the design of nondairy probiotics applying fruits, vegetables and cereals has raised great interest in the healthy food sector. The objective of this work was to assess the potential of germinated and malted oat substrates to support the growth of the probiotic cultures Lactobacillus acidophilus, Lactobacillus casei and Lactobacillus rhamnosus. Fermentations were carried out with distinctive oat substrates at inoculum levels of 3, 5 and 7% v/v, substrate concentrations of 3, 5 and 7% w/v and with sucrose addition 1·5% w/v. Lag phase profiles, maximum growth rates and maximal growths were evaluated; protein and sugar contents were also quantified. There was no significant effect (P > 0·05) of the inoculum size on the fermentation kinetics; however, oat media significantly affected the growth kinetics. In simple oat media, Lact. acidophilus exhibited biphasic growth patterns. Lactobacillus growth patterns were significantly affected (P viability of the probiotic lactobacilli; Lactobacillus casei exhibited better growth adaptability. The results also highlight that different weight in volume oat substrate concentrations has particular effects on Lact. casei growth kinetics. Our results contribute to a better understanding of oat-based media formulations as substrates for probiotic cultures. © 2014 The Society for Applied Microbiology.

    Animal models have greatly enriched our understanding of the molecular mechanisms of numerous types of cancers. Gastric cancer is one of the most common cancers worldwide, with a poor prognosis and high incidence of drug-resistance. However, most inbred strains of mice have proven resistant to gastric carcinogenesis. To establish useful models which mimic human gastric cancer phenotypes, investigators have utilized animals infected with Helicobacter species and treated with carcinogens. In addition, by exploiting genetic engineering, a variety of transgenic and knockout mouse models of gastric cancer have emerged, such as INS-GAS mice and TFF1 knockout mice. Investigators have used the combination of carcinogens and gene alteration to accelerate gastric cancer development, but rarely do mouse models show an aggressive and metastatic gastric cancer phenotype that could be relevant to preclinical studies, which may require more specific targeting of gastric progenitor cells. Here, we review current gastric carcinogenesis mouse models and provide our future perspectives on this field. PMID:24216700

    In contrast to patients with migraine with aura (MA) and migraine without aura (MO), most patients with familial hemiplegic migraine (FHM) do not report migraine-like attacks after pharmacologic provocation with glyceryl trinitrate (GTN), a donor of nitric oxide. In the present study, we examined...... patients with FHM without known gene mutations and hypothesized that 1) GTN would cause more migraine-like attacks in patients with FHM compared to controls, and 2) GTN would cause more migraine attacks in patients with FHM with coexisting MA or MO compared to the pure FHM phenotype....

    Genomic prediction of malting quality traits in barley shows the potential of applying genomic selection to improve selection for malting quality and speed up the breeding process. Genomic selection has been applied to various plant species, mostly for yield or yield-related traits such as grain dry matter yield or thousand kernel weight, and improvement of resistances against diseases. Quality traits have not been the main scope of analysis for genomic selection, but have rather been addressed by marker-assisted selection. In this study, the potential to apply genomic selection to twelve malting quality traits in two commercial breeding programs of spring and winter barley (Hordeum vulgare L.) was assessed. Phenotypic means were calculated combining multilocational field trial data from 3 or 4 years, depending on the trait investigated. Three to five locations were available in each of these years. Heritabilities for malting traits ranged between 0.50 and 0.98. Predictive abilities (PA), as derived from cross validation, ranged between 0.14 to 0.58 for spring barley and 0.40-0.80 for winter barley. Small training sets were shown to be sufficient to obtain useful PAs, possibly due to the narrow genetic base in this breeding material. Deployment of genomic selection in malting barley breeding clearly has the potential to reduce cost intensive phenotyping for quality traits, increase selection intensity and to shorten breeding cycles.

    Understanding lactic acid bacteria (LAB) fermentation behavior in malt wort is a milestone towards flavor improvement of lactic acid fermented malt beverages. Therefore, this study aims to outline deficiencies that may exist in malt wort fermentation. First, based on six LAB strains, cell viability and vitality were evaluated. Second, sugars, organic acids, amino acids, pH value and buffering capacity (BC) were monitored. Finally, the implication of key amino acids, fructose and wort BC on LAB growth was determined. Short growth phase coupled with prompt cell death and a decrease in metabolic activity was observed. Low wort BC caused rapid pH drop with lactic acid accumulation, which conversely increased the BC leading to less pH change at late-stage fermentation. Lactic acid content (≤3.9 g/L) was higher than the reported inhibitory concentration (1.8 g/L). Furthermore, sugars were still available but fructose and key amino acids lysine, arginine and glutamic acid were considerably exhausted (≤98%). Wort supplementations improved cell growth and viability leading to conclude that key amino acid depletion coupled with low BC limits LAB growth in malt wort. Then, a further increase in organic acid reduces LAB viability. This knowledge opens doors for LAB fermentation process optimization in malt wort. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Iris metastasis in patients with gastric cancer is extremely rare. Herein, it is aimed to report on a patient with gastric adenocarcinoma and iris metastasis. A 65-year-old patient with the history of gastric cancer was admitted for eye pain and eye redness on his left eye. There was ciliary injection, severe +4 cells with hypopyon in the anterior chamber and a solitary, friable, yellow-white, fleshy-creamy vascularized 2 mm × 4 mm mass on the upper nasal part of the iris within the left eye. The presented patient's mass lesion in the iris fulfilled the criteria of the metastatic iris lesion's appearance. The ocular metastasis occurred during chemotherapy. Iris metastasis can masquerade as iridocyclitis with pseudohypopyon or glaucoma. In patients with a history of gastric cancer that present with an iris mass, uveitis, and high intraocular pressure, ocular metastasis of gastric cancer should be a consideration.

    In this work, we perform a statistical investigation towards 50 high-mass clumps using data from the Bolocam Galactic Plane Survey (BGPS) and Millimetre Astronomy Legacy Team 90-GHz survey (MALT90). Eleven dense molecular lines (N2H+(1–0), HNC(1–0), HCO+(1–0), HCN(1–0), HN13C(1–0), H13CO+(1–0), C2H(1–0), HC3N(10–9), SiO(2–1), 13CS(2–1)and HNCO(44,0 ‑ 30,3)) are detected. N2H+ and HNC are shown to be good tracers for clumps in various evolutionary stages since they are detected in all the fields. The detection rates of N-bearing molecules decrease as the clumps evolve, but those of O-bearing species increase with evolution. Furthermore, the abundance ratios [N2H+]/[HCO+] and log([HC3N]/[HCO+]) decline with log([HCO+]) as two linear functions, respectively. This suggests that N2H+ and HC3N transform to HCO+ as the clumps evolve. We also find that C2H is the most abundant molecule with an order of magnitude 10‑8. In addition, three new infall candidates, G010.214–00.324, G011.121–00.128 and G012.215–00.118(a), are discovered to have large-scale infall motions and infall rates with an order of magnitude 10‑3 M ⊙ yr‑1.

    A heterodimer consisting of two or more different kinds of proteins can display an enormous number of distinct molecular architectures. The conformational entropy is an essential ingredient in the Helmholtz free energy and, consequently, these heterodimers can have a very complex phase structure. Here, it is proposed that there is a state of proteins, in which the different components of a heterodimer exist in different phases. For this purpose, the structures in the protein data bank (PDB) have been analyzed, with radius of gyration as the order parameter. Two major classes of heterodimers with their protein components coexisting in different phases have been identified. An example is the PDB structure 3DXC. This is a transcriptionally active dimer. One of the components is an isoform of the intra-cellular domain of the Alzheimer-disease related amyloid precursor protein (AICD), and the other is a nuclear multidomain adaptor protein in the Fe65 family. It is concluded from the radius of gyration that neither of the two components in this dimer is in its own collapsed phase, corresponding to a biologically active protein. The UNRES energy function has been utilized to confirm that, if the two components are separated from each other, each of them collapses. The results presented in this work show that heterodimers whose protein components coexist in different phases, can have intriguing physical properties with potentially important biological consequences.

    2005-01-01

    Shape coexistence in the light krypton isotopes was studied in a series of experiments at GANIL using various experimental techniques. A new low-lying 0+ state, a so-called shape isomer, was found in delayed conversion-electron spectroscopy after fragmentation reactions. The systematics of such low-lying 0+ states suggests that the ground states of the isotopes 78Kr and 76Kr have prolate deformation, while states with prolate and oblate shape are practically degenerate and strongly mixed in 74Kr, and that the oblate configuration becomes the ground state in 72Kr. This scenario was tested in experiments performing low-energy Coulomb excitation of radioactive 76Kr and 74Kr beams from the SPIRAL facility. Both transitional and diagonal electromagnetic matrix elements were extracted from the observed γ-ray yields. The results find the prolate shape for the ground-state bands in 76Kr and 74Kr and an oblate deformation for the excited 2 2 + state in 74Kr, confirming the proposed scenario of shape coexistence

    The presence of bronchiectasis (BR) in patients with rheumatoid arthritis (RA) has been recognized for many decades; nevertheless, little research has been undertaken in this area. It is important to recognize that BR coexistent with RA differs from the other types of BR. The purpose of this descriptive review was to delineate the epidemiology, etiology, risk factors, pulmonary function testing, imaging, prognosis and management of concomitant BR and RA. To inform our study we searched the PubMed, EMBASE, CINAHL, and MEDLINE databases, using combinations of the following key words: computed tomography, lung function tests, rheumatoid arthritis, bronchiectasis, biological agents, and interstitial lung disease. The number of published papers covering this topic is limited, but several relevant conclusions can be drawn. Patients with concomitant RA and BR have worse obstructive airways disease, increased susceptibility to recurrent pulmonary infections, faster lung function decline, and higher mortality, compared with subjects with either RA or BR alone. The use of disease-modifying anti-rheumatic drugs (both biological and non-biological) for RA in RA-BR patients imparts a further challenge in managing these patients. Although there are not any published guidelines on the management of coexisting RA-BR, we have attempted to provide such recommendations, based on the literature review and our experience.

    To evaluate the treatment outcome in patients with mucosa associated lymphoid tissue (MALT) lymphoma in terms of response to treatment, progression-free and overall survivals as well as prognostic factors. Patients and Methods: Between 1995 and 2002,40 patients with clinical stages (CS) I-IV MALT lymphoma were treated at NEMROCK. The progression free survival (PFS) and overall survival (OAS) were calculated using the Kaplan Meier technique. Thirty-one patients (77.5%) had CS I-II and 9 (22.5%) had CS III-IV disease. Twenty of the 31 CS I-II patients received radiation therapy alone, five patients received chemotherapy, while three patients were treated by triple therapy (Amoxicillin, Omeperazole, Clarithromycin). Among the 9 CS III-IV patients, treatment included chemotherapy alone (6 patients), chemo radiation (2 patients) and surgery (one patient). The median followup period was 40 months. 19 out of twenty patients with CS I-II treated by radiation therapy alone had a 95% response rate (CR 85% - PR 10%). Among the study population (40 patients), the 5 year OAS and PFS were 86% and 66%, respectively. The 5 year OAS was 86% and PFS was 72% among CS III patients; the corresponding estimates in CS III-IV patients were 70% and 28%, respectively. Using multivariate analysis, there was a significant correlation between the stage of the disease, site of presentation (non GIT) and the overall survival. Modest doses of radiation therapy provide better local control in patients with early stage MALT lymphoma. The poor PFS in advanced staged disease suggests the need for further clinical trials evaluating novel drug approaches taking into consideration the biological behavior and the indolent nature of such disease entity

    Full Text Available This study aimed to describe gastric ulcer in donkeys. 10 donkeys (Equus asinus were studied in Bodonal de la Sierra, Badajoz-Extremadura, Spain. They were referred for necropsy and dead due to non-digestive causes. 4 males and 6 females were examined. The ages were classified of 4-16 years old. The stomach and gastric mucosa was evaluated for classified Merrit, 2003. Samples of gastric tissue were collected. The samples fixed in formalin were processed by conventional histological techniques and examined by histopathology. None of the donkeys presented clinical signs for gastric ulcers syndrome. Of the 10 donkeys studied, 10% had Grade 0; 30% Grade 1; 40% Grade 2; 10% Grade 3; and 10% Grade 4. In 30% (3/10 parasites such as Gasterophilus sp. were observed. The histological slices revealed severe damage on the gastric mucosa, a loss of continuity of the gastric mucosa with corium exposure, and subchorionic edema with parakeratotic hyperkeratosis, together with a mixed lymphoplasmocytic mononuclear infiltrate. In conclusion, we reported gastric ulcers syndrome in donkeys in Spain.

  1. Ancient Origin of the CARD–Coiled Coil/Bcl10/MALT1-Like Paracaspase Signaling Complex Indicates Unknown Critical Functions

    Directory of Open Access Journals (Sweden)

    2018-05-01

    Full Text Available The CARD–coiled coil (CC/Bcl10/MALT1-like paracaspase (CBM signaling complexes composed of a CARD–CC family member (CARD-9, -10, -11, or -14, Bcl10, and the type 1 paracaspase MALT1 (PCASP1 play a pivotal role in immunity, inflammation, and cancer. Targeting MALT1 proteolytic activity is of potential therapeutic interest. However, little is known about the evolutionary origin and the original functions of the CBM complex. Type 1 paracaspases originated before the last common ancestor of planulozoa (bilaterians and cnidarians. Notably in bilaterians, Ecdysozoa (e.g., nematodes and insects lacks Bcl10, whereas other lineages have a Bcl10 homolog. A survey of invertebrate CARD–CC homologs revealed such homologs only in species with Bcl10, indicating an ancient common origin of the entire CBM complex. Furthermore, vertebrate-like Syk/Zap70 tyrosine kinase homologs with the ITAM-binding SH2 domain were only found in invertebrate organisms with CARD–CC/Bcl10, indicating that this pathway might be related to the original function of the CBM complex. Moreover, the type 1 paracaspase sequences from invertebrate organisms that have CARD–CC/Bcl10 are more similar to vertebrate paracaspases. Functional analysis of protein–protein interactions, NF-κB signaling, and CYLD cleavage for selected invertebrate type 1 paracaspase and Bcl10 homologs supports this scenario and indicates an ancient origin of the CARD–CC/Bcl10/paracaspase signaling complex. By contrast, many of the known MALT1-associated activities evolved fairly recently, indicating that unknown functions are at the basis of the protein conservation. As a proof-of-concept, we provide initial evidence for a CBM- and NF-κB-independent neuronal function of the Caenorhabditis elegans type 1 paracaspase malt-1. In conclusion, this study shows how evolutionary insights may point at alternative functions of MALT1.

  5. Limits on new forces coexisting with electromagnetism

    1994-01-01

    We consider the limits arising from different electromagnetic systems on the existence of a possible new electromagnetic analogue of the fifth force. Although such a force may have no intrinsic connection to electromagnetism (or gravity), its effects could be manifested through various anomalies in electromagnetic systems, for appropriate values of the coupling strength and range. Our work generalizes that of Bartlett and Loegl (who considered the case of a massive vector field coexisting with massless electrodynamics) to encompass a broad class of phenomenological interactions mediated by both scalar and vector exchanges. By combining data from both gravitational and electromagnetic systems, one can eventually set limits on a new force whose range λ extends from the subatomic scale (λ∼10 -15 m) to the astrophysical scale (λ∼10 12 m)

    Giant cell fibroblastoma (GCF) is a rare soft tissue tumour that occurs almost exclusively in children younger than 10 years of age and is mostly located in the superficial soft tissues of the back and thighs. We present a rare case of GCF with encephalocele in a 1.5-year-old boy who presented with a swelling in the occipital area of the scalp since birth. CT scan suggested encephalocele without any suspicion of a mass lesion. On histopathology, an ill-defined proliferation of fibroblasts in a heavily collagenised and focally myxoid stroma was seen containing numerous multinucleated cells having a floret-like appearance along with mature glial tissue bordering a cystic space. Immunohistochemically, the stromal cells were positive for both, vimentin (diffuse) and CD34 (focal) thereby confirming the histological diagnosis of GCF. This case highlights the unusual coexistence of GCF with congenital defects and its histogenetic resemblance to dermatofibrosarcoma protuberans.

    Healthy and active ageing has become an ideal in Western societies. In the Nordic countries, this ideal has been supported through a policy of help to self-help in elder care since the 1980s. However, reforms inspired by New Public Management (NPM) have introduced a new policy principle of consumer......-oriented service that stresses the wishes and priorities of older people. We have studied how these two principles are applied by care workers in Denmark. Is one principle or logic replacing the other, or do they coexist? Do they create tensions between professional knowledge and the autonomy of older people......? Using neo-institutional theory and feminist care theory, we analysed the articulation of the two policy principles in interviews and their logics in observations in four local authorities. We conclude that help to self-help is the dominant principle, that it is deeply entrenched in the identity...

  9. Coexistence of pheochromocytoma with uncommon vascular lesions

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Background: Pheochromocytoma/paragangliomas have been described to be associated with rare vascular abnormalities like renal artery stenosis. Coexistence of physiologically significant renal artery lesions is a compounding factor that alters management and prognosis of pheochromocytoma patients. Apart from individual case reports, data on such association in Indian population is not available. The aim of this study is to find the nature and prevalence of associated vascular abnormalities. Materials and Methods: From 1990 to 2010, a total of 50 patients were diagnosed with pheochromocytoma/paragangliomas. Hospital charts of these patients were reviewed retrospectively to identify those with unusual vascular abnormalities. Available literature was also reviewed. Results: Of the 50 patients with pheochromocytoma, 7 (14% had coexisting vascular lesions including renal artery stenosis in 4, aortoarteritis in 1, aortic aneurysm in 1 and inferior vena cava thrombosis in 1. Pheochromocytoma was adrenal in 42 and extra adrenal in 8. Laparoscopic adrenalectomy was done in the patients. One patient with renal artery stenosis due to intimal fibrosis was subjected to percutaneous balloon angioplasty; the other three improved after adrenalectomy and lysis of fibrous adhesive bands. The patient with aortoarteritos was treated with oral steroids. Inferior vena cava thrombosis was reversed with anticoagulants. The patient with abdominal aortic aneurysm was advised for annual follow-up on account of its size of 4.5 cm and asymptomatic presentation. Conclusion: There are multiple mechanisms that can lead to renal artery stenosis and other vascular abnormalities in a case of pheochromocytoma. A high index of suspicion is necessary to enable both entities to be diagnosed preoperatively and allow proper planning of surgical therapy. Incomplete diagnosis may lead to persistent hypertension postoperatively in a case of associated renal artery stenosis.

  10. [AFP-producing gastric cancer and hepatoid gastric cancer].

    2017-11-23

    AFP-producing gastric cancer(AFPGC) and hepatoid adenocarcinoma of the stomach (HAS) are two special subtypes of gastric cancer. There are both correlation and difference between them. AFPGC is usually identified as primary gastric cancer with serum AFP level more than 20 ng/ml or showed AFP positive staining by immunohistochemistry. The diagnosis of HAS is mainly dependent on the pathological character of hepatocellular carcinoma-like differentiation of gastric cancer. The morbidity of AFPGC and HAS are rather low, especially the incidence of HAS is about 1%. The prognoses of these two subtypes are poorer than that of common gastric adenocarcinoma, due to a high incidence rate of liver metastasis and lymph node metastasis. With the development of next-generation sequencing and other genomic technologies, gastric cancers, including these two rare subtypes, are now being investigated in more detail at the molecular level. Treatment remains the biggest challenge, early diagnosis and radical resection can dramatically improve patients'prognosis. Monitoring serum AFP and abdominal imaging examination during follow-up is important for early detection of liver metastasis. In combination with local treatment methods such as transarterial chemoembolization and radiofrequency ablation of liver may further extend patients'survival time. Targeted therapy owes a great potential value in the future.

    Malt sprout (MS), a by-product of the malt industry obtained by removing rootlets and sprouts from the seed of germinated barley ( Hordeum vulgare L.), was used as culture, dehydration and storage medium of three strains of lactobacilli: Lactobacillus salivarius CM-CIDCA 1231B and CM-CIDCA 1232Y and Lactobacillus plantarum CIDCA 83114. The three strains were grown in MS and MS supplemented with 20% w/v fructo-oligosaccharides (MS FOS). Bacterial growth was determined by registering the decrease of pH and by plate counting. Comparable results with those of microorganisms grown in MRS (controls) were observed in terms of lag times, ΔpH and acidification rates. Furthermore, during fermentation, a significant increase of DP6 (FOS with degree of polymerization 6) was observed at expenses of inulin and DP7, probably indicating their hydrolysis. A concomitant decrease of DP3, sucrose and monosaccharides was also observed, as result of their bacterial consumption during growth. The presence of FOS in the fermented media protected microorganisms during freeze-drying and storage, as no decrease of culturability was observed after 60 days at 4 °C (> 10 8 CFU/mL). Using MS appears as an innovative strategy for the production of lactobacilli at large scale, supporting their use for the elaboration of functional foods containing prebiotics and probiotics.

    This study aims to define the aroma composition and key aroma compounds of barley malt wort beverages produced from fermentation using six lactic acid bacteria (LAB) strains. Gas chromatography mass spectrometry-olfactometry and flame ionization detection was employed; key aroma compounds were determined by means of aroma extract dilution analysis. Fifty-six detected volatile compounds were similar among beverages. However, significant differences were observed in the concentration of individual compounds. Key aroma compounds (flavor dilution (FD) factors ≥16) were β-damascenone, furaneol, phenylacetic acid, 2-phenylethanol, 4-vinylguaiacol, sotolon, methional, vanillin, acetic acid, nor-furaneol, guaiacol and ethyl 2-methylbutanoate. Furthermore, acetaldehyde had the greatest odor activity value of up to 4266. Sensory analyses revealed large differences in the flavor profile. Beverage from L. plantarum Lp. 758 showed the highest FD factors in key aroma compounds and was correlated to fruity flavors. Therefore, we suggest that suitable LAB strain selection may improve the flavor of malt based beverages. Copyright © 2017 Elsevier Ltd. All rights reserved.

    We retrospectively reviewed the results of radiotherapy for localized ocular adnexal MALT lymphoma (OAML) to investigate the risk factors of cataract. Sixty-seven patients with stage IE OAML treated with radiotherapy at Seoul St. Mary’s Hospital from 2001 to 2016 were included. Median treatment dose was 30 Gy. Lens protection was done in 52 (76%) patients. Radiation therapy (RT) extent was as follows: superficial (82.1%), tumor mass (4.5%), and entire orbital socket (13.4%). The risk factors for symptomatic cataract were analyzed using the Cox proportional hazard model. Median follow-up time was 50.9 months (range, 1.9 to 149.4 months). All patients were alive at the time of analysis. There were 7 recurrences and there was no local recurrence. Median time to recurrence was 40.4 months. There were 14 cases of symptomatic cataract. Dose >30 Gy had hazard ratio of 3.47 for cataract (p = 0.026). Omitting lens protection showed hazard ratio of 4.10 (p = 0.008). RT achieves excellent local control of ocular MALT lymphoma. Consideration of RT-related factors such as lens protection and radiation dose at the stage of RT planning may reduce the risk of RT-induced cataract after radiotherapy.

    The incidence of gastrointestinal stromal tumours (GIST) has increased in recent years. A number of authors have attempted to define the actual nature of these tumours. Immunohistochemistry highlighting the positivity of tyrosine-kinase (CD117/c-Kit) has revealed the difference between gastrointestinal stromal tumours and other mesenchymal tumours and, therefore, the possibility of medical rather than surgical therapy. We retrospectively reviewed 19 patients affected by primary gastric GIST, who underwent surgery in recent years with subsequent follow-up. Gastroscopy and gastrointestinal tract radiography were used not only to obtain the diagnosis but also to establish the size, density, contours, ulceration, regional lymphadenopathy, mesenteric infiltration and the presence of metastases. The aim of this study was to evaluate the roles of endoscopy and radiology in this pathology and the advantages and limitations of each individual technique.

    There have been sporadic reports about synchronous as well as metachronous gastric adenocarcinoma and primary gastric lymphoma. Many reports have dealt with metachronous gastric adenocarcinoma in mucosa-associated lymphoid tissue lymphoma of stomach. But to our knowledge, there have been no reports that document the increased incidence of metachronous gastric adenocarcinoma in patients with gastric diffuse large B-cell lymphoma. This retrospective study was conducted to estimate the incidence of metachronous gastric adenocarcinoma after primary gastric lymphoma treatment, especially in diffuse large B-cell lymphoma. The retrospective cohort study of 139 primary gastric lymphoma patients treated with radiotherapy at our hospital. Mean observation period was 61.5 months (range: 3.7-124.6 months). Patients profile, characteristics of primary gastric lymphoma and metachronous gastric adenocarcinoma were retrieved from medical records. The risk of metachronous gastric adenocarcinoma was compared with the risk of gastric adenocarcinoma in Japanese population. There were 10 (7.2%) metachronous gastric adenocarcinoma patients after treatment of primary gastric lymphomas. It was quite high risk compared with the risk of gastric carcinoma in Japanese population of 54.7/100,000. Seven patients of 10 were diffuse large B-cell lymphoma and other 3 patients were mixed type of diffuse large B-cell lymphoma and mucosa associated lymphoid tissue lymphoma. Four patients of 10 metachronous gastric adenocarcinomas were signet-ring cell carcinoma and two patients died of gastric adenocarcinoma. Metachronous gastric adenocarcinoma may have a more malignant potential than sporadic gastric adenocarcinoma. Old age, Helicobacter pylori infection and gastric mucosal change of chronic gastritis and intestinal metaplasia were possible risk factors for metachronous gastric adenocarcinoma. There was an increased risk of gastric adenocarcinoma after treatment of primary gastric lymphoma

    The few published case reports of co-existent disease with phenylketonuria (PKU) are mainly genetic and familial conditions from consanguineous marriages. The clinical and demographic features of 30 subjects with PKU and co-existent conditions were described in this multi-centre, retrospective cohort study. Diagnostic age of PKU and co-existent condition, treatment regimen, and impact of co-existent condition on blood phenylalanine (Phe) control and PKU management were reported. 30 patients (11 males and 19 females), with PKU and a co-existent condition, current median age of 14 years (range 0.4 to 40 years) from 13 treatment centres from Europe and Turkey were described. There were 21 co-existent conditions with PKU; 9 were autoimmune; 6 gastrointestinal, 3 chromosomal abnormalities, and 3 inherited conditions. There were only 5 cases of parental consanguinity. Some patients required conflicting diet therapy (n=5), nutritional support (n=7) and 5 children had feeding problems. There was delayed diagnosis of co-existent conditions (n=3); delayed treatment of PKU (n=1) and amenorrhea associated with Grave's disease that masked a PKU pregnancy for 12 weeks. Co-existent conditions adversely affected blood Phe control in 47% (n=14) of patients. Some co-existent conditions increased the complexity of disease management and increased management burden for patients and caregivers. Occurrence of co-existent disease is not uncommon in patients with PKU and so investigation for co-existent disorders when the clinical history is not completely consistent with PKU is essential. Integrating care of a second condition with PKU management is challenging. Copyright © 2015 Elsevier Inc. All rights reserved.

  17. Gastric Adenomyoma: The Unexpected Mimicker

    2017-01-01

    Full Text Available Gastric adenomyoma is a rare benign tumor composed of epithelial structures and smooth muscle stroma. Here, we report an unusual case of gastric adenomyoma mostly composed of smooth muscle that was incidentally found during a laparoscopic intervention. On radiology, it mimicked an acquired hypertrophic pyloric stenosis in an adult patient, and pathologically it resembled a pure smooth muscle hamartoma. Complete submission of the lesion for histology was necessary to find the epithelial component and make the right diagnosis. As a mimicker of benign and malignant entities, gastric adenomyoma is usually an unexpected finding after surgery. The aim of this report is to analyze this adenomyoma variant in the setting of an unexplained thickening of the gastric wall, with explanations concerning histogenesis and biological potential.

    627 cases of gastric cancer treated surgically during the last 5 years, at the Hospital Nacional "Edgardo Rebagliati Martins" from Instituto Peruano de Seguridad Social (Lima-Perú) were revised. 4 of the patients had been operated before of hemigastrectomy or antrectomy with pyloroplasty for peptic ulcer. The time between the first operation and diagnosis of cancer of the gastric stump was more than 20 years. 3 of these cases were able to be resected. The international incidence of cancer in the gastric stump is 1.1% to 9.2% according to different authors. The risk is higher after 15 years. In the pathogenesis are advocated the lower gastric acidity, biliary reflux, the presence of bacteria, the formation of nitrosamines, intestinal metaplasia, etc. Is necessary to perform periodic endoscopic survey in patients who were treated surgically of peptic ulcer with antrectomy or hemigastrectomy with more than 15 years of evolution.

Most patients who experience gastric volvulus present with mild or intermittent gastric obstructive symptoms. However, severe acute gastric volvulus can result in complete gastric outlet obstruction and ischemia. Consequently, acute gastric volvulus warrants immediate evaluation and management. The goals of management are to relieve the obstruction and prevent recurrent volvulus. Techniques to manage gastric volvulus depend on patient characteristics and the presence of gastric ischemia. In the absence of gastric ischemia, gastric volvulus can be managed with anterior abdominal wall gastropexy or paraesophageal hernia repair. If gastric ischemia is present, operative resection of the affected portion of the stomach is indicated. When operative management is indicated, many patients with gastric volvulus can be managed with minimally invasive (laparoscopic, endoscopic, or laparoendoscopic techniques.

    The purpose of this work was to study retrospectively the molecular response and outcome of 19 gastric mucosa associated lymphoid tissue (MALT) lymphoma patients achieving histological remission after chemotherapy or surgery. Immunoglobulin heavy chain variable (IgV(H)) gene rearrangements were studied by PCR in biopsies obtained at diagnosis and follow-up. Presence of t(11;18)(q21;q21) was studied by FISH or RT-PCR. Sequencing analysis of three t(11;18)(q21;q21) positive and two negative lymphomas with persistent monoclonal IgV(H) rearrangements was also performed. Long-term IgV(H) monoclonality was demonstrated in 11/19 patients (58%); in five of them monoclonal rearrangements were present in all samples throughout the follow-up. Persistent IgV(H) monoclonality was detected a median of 49 months after the achievement of histological response and did not condition histological relapse in most cases. All three t(11;18)(q21;q21) positive patients had maintained IgV(H) monoclonality and sequencing analyses revealed the same mutated IgV(H) alleles in the diagnostic and the follow-up samples. Over half of the patients with gastric MALT lymphoma with histological response after chemotherapy and/or surgery have long-term persistent monoclonality. The presence of t(11;18)(q21;q21) seems to condition long-term persistence of the initial lymphoma clone.trade mark.

    We consider the coexistence of hyperon and π condensation in neutron stars. The coexistence phase may occur because of the strong ΛΣπ coupling. Hyperon can appear under π condensation, because short range repulsion reduce the π-baryon p wave attraction. The system approaches the Fermi gas because of this reduction. (author)

    The Database of Human Gastric Cancer (DBGC) is a comprehensive database that integrates various human gastric cancer-related data resources. Human gastric cancer-related transcriptomics projects, proteomics projects, mutations, biomarkers and drug-sensitive genes from different sources were collected and unified in this database. Moreover, epidemiological statistics of gastric cancer patients in China and clinicopathological information annotated with gastric cancer cases were also integrated into the DBGC. We believe that this database will greatly facilitate research regarding human gastric cancer in many fields. DBGC is freely available at http://bminfor.tongji.edu.cn/dbgc/index.do PMID:26566288

    Cross-sectional gastric antral area (GAA) measurements by ultrasonography (US) have been proposed for preoperative assessment of gastric volume in adults but not been validated in children. This study investigates whether in children gastric volumes can be predicted by US performed in different patient positions. Gastric fluid and air volumes were examined by magnetic resonance imaging before or up to 120 min after ingestion of 7 ml·kg(-1) diluted raspberry syrup in healthy volunteers who had fasted overnight. GAA was measured with US three times each in supine (SUP), elevated 45° degree supine (E45) and right decubital (RDC) position using imaging planes defined by vascular landmarks. Correlation coefficients (Pearson) between GAA and gastric volumes were calculated and Bland-Altman analysis performed. Sixteen children aged from 6.4 to 12.8 (9.2) years were included in 23 examinations: 6 after overnight fasting, 3 directly after, and 14 with a delay of 74 ± 35 min after fluid intake. GAA was 221 ± 116, 218 ± 112, and 347 ± 188 mm(2) for SUP, E45, and RDC position, respectively. The best correlation between body weight corrected total gastric/gastric fluid volume (TGV(w)/GFV(w)) with GAA was found for RDC position (R = 0.79; P < 0.01/R = 0.78; P < 0.01). Bias and precision of calculated and measured GFV(w) was 0 ± 2.8 ml·kg(-1). Correlations between GAA and TGV(w) or GFV(w) in children are best in the RDC position, but not sufficient to predict GFV(w) with a given GAA. Interpretation of isolated GAA values may be misleading. © 2011 Blackwell Publishing Ltd.

  12. Occurrence of (Z)-3,4-Dideoxyglucoson-3-ene in Different Types of Beer and Malt Beer as a Result of 3-Deoxyhexosone Interconversion.

    In beer, 3-deoxyglucosone (3-DG) and 3-deoxygalactosone (3-DGal) are important sugar degradation products, but little is known about the relevance of the interconversion reaction between these compounds in different types of beer. In the present study, 3-DG was quantitated at concentrations of 12.9-52.7 mg/L and 3-DGal at concentrations of 6.0-26.4 mg/L in different types of beer (pilsner, wheat, bock, dark, and alcohol-free beers). The concentrations in malt beer tended to be higher. Largely overlapping concentration ranges precluded a classification of beers by their 3-deoxyglycosone contents. 3,4-Dideoxyglucoson-3-ene (3,4-DGE) was identified as an important intermediate and quantitated in beer and malt beer for the first time. The E and Z isomers of the corresponding quinoxaline were synthesized by a new synthetic approach and isolated by semipreparative HPLC. An assay was developed for quantitation of (E)- and (Z)-3,4-DGE by HPLC-MS/MS, and the Z isomer was determined at concentrations of 0.3-1.7 mg/L in beer and 0.5-4.8 mg/L in malt beer samples. The E isomer was shown to be of little importance. Concentrations of 5-hydroxymethylfurfural (HMF) were twice as high as those of (Z)-3,4-DGE in beer samples (0.4-3.7 mg/L) but much higher in malt beer samples (1.6-336 mg/L).

  15. Gastric lactobezoar - a rare disorder?

    Full Text Available Abstract Gastric lactobezoar, a pathological conglomeration of milk and mucus in the stomach of milk-fed infants often causing gastric outlet obstruction, is a rarely reported disorder (96 cases since its first description in 1959. While most patients were described 1975-1985 only 26 children have been published since 1986. Clinically, gastric lactobezoars frequently manifest as acute abdomen with abdominal distension (61.0% of 96 patients, vomiting (54.2%, diarrhea (21.9%, and/or a palpable abdominal mass (19.8%. Respiratory (23.0% and cardiocirculatory (16.7% symptoms are not uncommon. The pathogenesis of lactobezoar formation is multifactorial: exogenous influences such as high casein content (54.2%, medium chain triglycerides (54.2% or enhanced caloric density (65.6% of infant milk as well as endogenous factors including immature gastrointestinal functions (66.0%, dehydration (27.5% and many other mechanisms have been suggested. Diagnosis is easy if the potential presence of a gastric lactobezoar is thought of, and is based on a history of inappropriate milk feeding, signs of acute abdomen and characteristic features of diagnostic imaging. Previously, plain and/or air-, clear fluid- or opaque contrast medium radiography techniques were used to demonstrate a mass free-floating in the lumen of the stomach. This feature differentiates a gastric lactobezoar from intussusception or an abdominal neoplasm. Currently, abdominal ultrasound, showing highly echogenic intrabezoaric air trapping, is the diagnostic method of choice. However, identifying a gastric lactobezoar requires an investigator experienced in gastrointestinal problems of infancy as can be appreciated from the results of our review which show that in not even a single patient gastric lactobezoar was initially considered as a possible differential diagnosis. Furthermore, in over 30% of plain radiographs reported, diagnosis was initially missed although a lactobezoar was clearly

    Full Text Available Gastric bezoars are rare and are usually found incidentally. They can sometimes cause severe complications, including gastric outlet obstruction (GOO or gastric pneumatosis (GP. In cases of bezoars with GP, the optimal treatment strategy has not yet been defined. We report the case of an 89-year-old man with a history of type 2 diabetes mellitus and hypertension who presented to our emergency room with a 2-day history of upper abdominal pain, nausea, and vomiting. Physical examination revealed no rebound tenderness or guarding, and laboratory values revealed no elevation of the serum lactate level. A computed tomography scan of the abdomen showed a dilated stomach with significant fluid collection, GOO, and GP due to a 42 × 40 mm mass composed of fat and air densities. Emergency esophagogastroduodenoscopy revealed two gastric bezoars, one of which was incarcerated in the pyloric region. We used various endoscopic devices to successfully break and remove the bezoars. We used endoscopic forceps and a water jet followed by an endoscopic snare to cut the bezoars into several pieces and remove them with an endoscopic net. Follow-up endoscopy confirmed that the gastric bezoar had been completely removed. As seen in this case, endoscopic treatment may be a safe and viable option for the extraction of gastric bezoars presenting with GOO and GP.

    To assess the diagnostic performance of CT signs of gastric volvulus in both confirmed cases and control subjects. We retrospectively reviewed CT findings in 10 patients with surgically confirmed acute gastric volvulus and 20 control subjects with gastric distension. Two radiologists independently evaluated CT images for risk factors of gastric volvulus, direct findings of gastric volvulus by assessing gastric dilatation, the presence of an antropyloric transition point, the respective position of the different stomach segments and of the greater and lesser curvatures, stenosis of the gastric segments through the oesophageal hiatus and for findings of gastric ischemia. The sensitivity and specificity of each finding were calculated. The most sensitive direct signs of gastric volvulus were an antropyloric transition point without any abnormality at the transition zone and the antrum at the same level or higher than the fundus. The presence of both these two findings as diagnostic criteria of gastric volvulus had 100% sensitivity and specificity for the diagnosis of gastric volvulus. There was no association between CT signs of ischemia and final bowel ischemia at pathology. CT is both highly sensitive and specific for diagnosing acute gastric volvulus. CT is highly reliable for diagnosing acute gastric volvulus with two findings. The two signs are gastropyloric transition zone and abnormal location of the antrum. This allows fast surgical management of this emergency.

    Guillain-Barre syndrome (GBS) and syringomyelia are diseases of different entities. GBS is an acute post-infectious autoimmune disease which is mediated by autoantibodies against the myelin of peripheral nerves. Syringomyelia is a chronic disease characterized by a cavity extending longitudinally inside the spinal cord. A 67-year-old man is being hospitalized due to severe numbness and ascending weakness in all limbs. On neurological examination, the motor power of all limbs are decreased and show absence of deep tendon reflexes (DTRs). The patient is being diagnosed with GBS on the basis of the acute clinical course, nerve conduction studies of segmental demyelinating polyneuropathy, and a finding of albuminocytologic dissociation in the cerebrospinal fluid. The patient is presented with a new set of symptoms thereafter, which composes of sensory changes in the upper extremities, the urinary dysfunction including frequency and residual urine, spastic bilateral lower extremities, and increased reflexes of the knee and the biceps at follow-up examinations. The spinal magnetic resonance imaging in the sagittal section revealed a syrinx cavity between the fifth cervical and the first thoracic vertebral segment in the cord. The somatosensory evoked potential show sensory pathway defects between both the brachial plexus and the brain stem. Thus, this patient is being diagnosed with both GBS and syringomyelia. We report a case of symptomatic syringomyelia coexisting with GBS. Since the GBS is presented with a progressive muscle weakness and reduced DTRs, the muscle weakness and stiffness in the extremities suggests a concurrent syringomyelia might be easily overlooked.

    A patient with a fulminant amebic colitis coexisting with intestinal tuberculosis had a sudden onset of crampy abdominal pain, mucoid diarrhea, anorexia, fever and vomiting with signs of positive peritoneal irritation. Fulminant amebic colitis occurring together with intestinal tuberculosis is an uncommon event and may present an interesting patho-etiological relationship. The diagnosis was proven by histopathologic examination of resected specimen. Subtotal colectomy including segmental resection of ileum, about 80 cm in length, followed by exteriorization of both ends, was performed in an emergency basis. Despite all measures, the patient died on the sixth postoperative day. The exact relationship of fulminant amebic colitis and intestinal tuberculosis is speculative but the possibility of a cause and effect relationship exists. Fulminant amebic colitis may readily be confused with other types of inflammatory bowel disease, such as idiopathic ulcerative colitis, Crohn's disease, perforated diverticulitis and appendicitis with perforation. This report draws attention to the resurgence of tuberculosis and amebiasis in Korea, and the need for the high degree of caution required to detect it. PMID:11194200

    Shape coexistence between the strongly deformed ground state and the weakly deformed 02+ state in 98Sr has been a major topic of interest due to the energy difference of 215 keV, which is the smallest in all even-even nuclei. The electric monopole transition strength ρ2(E 0 ) is an important quantity that can relate the deformation difference and the shape mixing between the two 0+ states, which are admixtures of the vibrational (S) and the rotational (D) states in a simple mixing model. In a β -decay spectroscopy experiment, the experimental ρ2(E 0 ) was measured. A value of 0.053(5) is consistent with the previous measurement and was combined with known electric quadrupole transition strengths B (E 2 ) in calculations of a two-state mixing model. Based on a systematic study on neighboring Kr, Zr, and Mo isotopes, the mixing of the 0+ and 2+ states in 98Sr was determined to be 8.6% and 1.3%, respectively, corresponding to deformation parameters βD=0.38 (1 ) and βS=-0.23 (2 ) . These parameters reproduce experimental transition strengths well except for the 41+→21+ transition, which suggests a smaller D-band deformation for J ≥4 .

    Female caribou (Rangifer tarandus) are highly gregarious, yet there has been little study of the behavioral mechanisms that foster coexistence. Quantifying patterns of aggression between male and female, particularly in the only cervid taxa where both sexes grow antlers, should provide insight into these mechanisms. We asked if patterns of aggression by male and female caribou followed the pattern typically noted in other polygynous cervids, in which males display higher frequencies and intensity of aggression. From June to August in 2011 and 2012, we measured the frequency and intensity of aggression across a range of group sizes through focal animal sampling of 170 caribou (64 males and 106 females) on Adak Island in the Aleutian Archipelago, Alaska. Males in same-sex and mixed-sex groups and females in mixed-sex groups had higher frequencies of aggression than females in same-sex groups. Group size did not influence frequency of aggression. Males displayed more intense aggression than females. Frequent aggression in mixed-sex groups probably reflects lower tolerance of males for animals in close proximity. Female caribou were less aggressive and more gregarious than males, as in other polygynous cervid species.

    The management of pregnant women with active Hodgkin's disease (H.D.) should be individualized depending on the stage, the presence of infradiaphragmatic involvement, and age of gestation. Seventeen women aged 16-31 years with coexisting H.D. and pregnancy were followed between 1969 and 1982. H.D. was diagnosed during pregnancy in 15 patients and two became pregnant while on treatment. Seven women whose pregnancies were allowed to proceed uninterrupted were irradiated to supradiaphragmatic sites to doses of 1500-2000 rad during the second or third trimester; all had full term spontaneous normal deliveries and normal infants. Fetal doses ranged from 2-50 rad. Two patients treated with Vinblastine throughout three pregnancies delivered normal full term infants. Pregnancy was interrupted in six patients at 6-20 weeks of gestation for various reasons. In spite of several months delay in initiation of definitive therapy, the outcome of H.D. was not adversely affected in the majority of uninterrupted pregnancies as evidenced by long term disease-free survivals of 6-11 years in four of seven patients who were irradiated; the children now aged 6-11 years are also alive and reported normal

    Gastric cancer can be classified into two categories based on the absence or presence of symptoms at diagnosis. Differences in clinicopathological features and prognoses between asymptomatic gastric cancer (ACG) and symptomatic gastric cancer (SGC) can be used to inform diagnosis strategies and ultimately improve survival rates. All cases of gastric cancer (239 AGC, 323 SGC) diagnosed in our hospital between 1997 and 1999 were used in this study. ACG patients showed significantly higher frequency of males, cases of early cancer, cases found by a mass screening program, cases treated by endoscopic resection, cases treated by curative operation, cases of type 0 macroscopic finding, cases of histologically-differentiated type, and stage I cases. By contrast, SGC patients showed significantly higher numbers of cases treated by chemotherapy alone or best support care, cases of type 2, 3, and 4 macroscopic findings, cases occupying the whole stomach, and cases of stage II, III, IV. Statistically significant differences were also found for the 5-year survival rate (83.3% in AGC, 41.2% in SGC), the incidence of early cancer (90.1% in AGC, 83.7% in SGC), and for advanced cancer (38.7% in AGC, 22.7% in SGC). The higher incidence of advanced cases in SGC than in AGC (40.0% vs. 13.0%), coupled with the low 5-year survival rate of advanced SGC (22.7%), provides strong evidence of the importance of diagnosing gastric cancer during its asymptomatic period.

    Methanol, often generated in brewed wine, is highly toxic for human health. To decrease the methanol content of the brewed wine, atmospheric and room-temperature plasma (ARTP) was used as a new mutagenesis tool to generate a mutant of Saccharomyces cerevisiae with lower methanol content. Headspace gas chromatography was used to determine the identity and concentration of methanol with butyl acetate as internal standard in brewed wine. With 47.4% higher and 26.3% positive mutation rates were obtained, the ARTP jet exhibited a strong effect on mutation breeding of S. cerevisiae. The mutant S. cerevisiae S12 exhibited the lowest methanol content, which was decreased by 72.54% compared with that of the wild-type strain. Subsequently, the mutant S. cerevisiae S12 was used to ferment different combinations of malt and adjuncts for lower methanol content and higher alcoholic content. It was shown that the culture 6#, which was 60% malt, 20% wheat, and 20% corn, was the best combinations of malt and adjuncts, with the lowest methanol content (104.8 mg/L), and a relatively higher alcoholic content (15.3%, v/v). The optimal malt-adjunct culture 6#, treated with the glucoamylase dose of 0.04 U/mg of grain released the highest reducing sugars (201.6 mg/mL). It was indicated that the variation in reducing sugars among the combinations of malt and different adjuncts could be due to the dose of exogenous enzymes. © 2014 Institute of Food Technologists®

    Objective: To investigate the interventional therapy and its curative effect for progressing stage gastric cancer. Methods: two hundred and twelve patients with progressing stage gastric cancer were treated with arterial perfusion and arterial embolization. Gastric cardia cancer was treated through the left gastric artery and the left inferior phrenic artery or splenic artery. Cancers of lesser and greater gastric curvature was treated either through the left and right gastric arteries or common hepatic artery or through gastroduodenal artery, right gastroomental artery or splenic artery. Gastric antrum cancers were perfused through gastroduodenal artery or after the middle segmental embolization of right gastroomental artery. Results: One hundred and ninety three cases undergone interventional management were followed up. The CR + PR of gastric cardia cancer was 53.13%; gastric body cancer 44.44%; gastric antrum cancer 10%; recurrent cancer and remnant gastric cancer 0. There was no significant difference in outcome between gastric cardia cancer and gastric body cancer (P>0.05) but significant differences were shown both between gastric cardia cancer and gastric antrum cancer, and between gastric body cancer and gastric antrum cancer (P<0.05), with 1 year and 2 years survival rates of 81% and 56% respectively. Conclusion: The interventional therapeutic effect of progressing stage gastric cancers is different due to the different sites of the lesions in the gastric tissue. The curative effect of gastric cardia cancer and gastric body cancer is better than that of gastric antrum cancer, recurrent cancer and remnant gastric cancer. (authors)

    Full Text Available Acute gastric volvulus is a rare, but potentially life-threatening, cause of upper gastro-intestinal obstruction. The diagnosis can prove clinically challenging, and hence there is increased reliance on imaging. There are different types of gastric volvulus, with the variant presented in our case being the less commonly encountered mesenteroaxial gastric volvulus. Some of the CT features of gastric volvulus are described, and the usefulness of CT in assisting with the diagnosis is highlighted.

    Full Text Available Acute gastric dilatation is a rare surgical condition in children, which often results from blunt abdominal trauma. This condition is characterized by the gut-brain connection disorder or gastric muscular layer damage, which results in atony. Gradual gastric stretching with fluid contents and gases in the end leads to the development of various types of intestinal obstruction. When conservative measures are not sufficient (in rare cases, it is reasonable to resort to operative intervention. Several cases of such a pathology have been published around the world. This condition has been observed not only at the blunt abdominal trauma, but also at lesions of central and peripheral nervous systems and in patients with anorexia nervosa and bulimia in the event of excessive food consumption. The article presents a clinical case study and a follow-up analysis of a child with posttraumatic acute gastric dilatation. The authors describe clinical manifestations, pathogenesis and diagnostic algorithm, which allowed establishing this rare diagnosis. Along with the conventional drugs and intensive care measures, the treatment involved a complex of mini-invasive endosurgical and endoscopic manipulations, including laparoscopic jejunostomy, which was performed in order to provide long-term enteral feeding. The clinical case study demonstrated that the use of diagnostic laparoscopy helps to establish nature of the gastric damage correctly and formulate the following optimal treatment tactics on the basis of the obtained data.

    Although many genetic alterations have been reported in gastric cancer, it is not known whether all gastric tumors are capable of indefinite proliferative potential, e.g., immortality. The expression of telomerase and stabilization of telomeres are concomitant with the attainment of immortality in tumor cells; thus, the measurement of telomerase activity in clinically obtained tumor samples may provide important information useful both as a diagnostic marker to detect immortal cancer cells in clinical materials and as a prognostic indicator of patient outcome. Telomerase activity was analyzed in 66 primary gastric cancers with the use of a PCR-based assay. The majority of tumors (85%) displayed telomerase activity, but telomerase was undetectable in 10 tumors (15%), 8 of which were early stage tumors. Most of the tumors with telomerase activity were large and of advanced stages, including metastases. Survival rate of patients of tumors with detectable telomerase activity was significantly shorter than that of those without telomerase activity. Alterations of telomere length (reduced/elongated terminal restriction fragments) were detected in 14 of 66 (21%) gastric cancers, and all 14 had telomerase activity. Cellular DNA contents revealed that all 22 aneuploid tumors had detectable telomerase activity. The present results indicate that telomerase activation may be required as a critical step in the multigenetic process of tumorigenesis, and that telomerase is frequently but not always activated as a late event in gastric cancer progression.

  16. Gastric residual volume (GRV) and gastric contents measurement by refractometry.

    Traditional use of gastric residual volumes (GRVs), obtained by aspiration from a nasogastric tube, is inaccurate and cannot differentiate components of the gastric contents (gastric secretion vs delivered formula). The use of refractometry and 3 mathematical equations has been proposed as a method to calculate the formula concentration, GRV, and formula volume. In this paper, we have validated these mathematical equations so that they can be implemented in clinical practice. Each of 16 patients receiving a nasogastric tube had 50 mL of water followed by 100 mL of dietary formula (Osmolite HN, Abbott Laboratories, Columbus, OH) infused into the stomach. After mixing, gastric content was aspirated for the first Brix value (BV) measurement by refractometry. Then, 50 mL of water was infused into the stomach and a second BV was measured. The procedure of infusion of dietary formula (100 mL) and then water (50 mL) was repeated and followed by subsequent BV measurement. The same procedure was performed in an in vitro experiment. Formula concentration, GRV, and formula volume were calculated from the derived mathematical equations. The formula concentrations, GRVs, and formula volumes calculated by using refractometry and the mathematical equations were close to the true values obtained from both in vivo and in vitro validation experiments. Using this method, measurement of the BV of gastric contents is simple, reproducible, and inexpensive. Refractometry and the derived mathematical equations may be used to measure formula concentration, GRV, and formula volume, and also to serve as a tool for monitoring the gastric contents of patients receiving nasogastric feeding.

  20. Exposure to Glycolytic Carbon Sources Reveals a Novel Layer of Regulation for the MalT Regulon

    Directory of Open Access Journals (Sweden)

    Sylvia A. Reimann

    2011-01-01

    Full Text Available Bacteria adapt to changing environments by means of tightly coordinated regulatory circuits. The use of synthetic lethality, a genetic phenomenon in which the combination of two nonlethal mutations causes cell death, facilitates identification and study of such circuitry. In this study, we show that the E. coli ompR malTcon double mutant exhibits a synthetic lethal phenotype that is environmentally conditional. MalTcon, the constitutively active form of the maltose system regulator MalT, causes elevated expression of the outer membrane porin LamB, which leads to death in the absence of the osmoregulator OmpR. However, the presence and metabolism of glycolytic carbon sources, such as sorbitol, promotes viability and unveils a novel layer of regulation within the complex circuitry that controls maltose transport and metabolism.

    To assess the diagnostic performance of CT signs of gastric volvulus in both confirmed cases and control subjects. We retrospectively reviewed CT findings in 10 patients with surgically confirmed acute gastric volvulus and 20 control subjects with gastric distension. Two radiologists independently evaluated CT images for risk factors of gastric volvulus, direct findings of gastric volvulus by assessing gastric dilatation, the presence of an antropyloric transition point, the respective position of the different stomach segments and of the greater and lesser curvatures, stenosis of the gastric segments through the oesophageal hiatus and for findings of gastric ischemia. The sensitivity and specificity of each finding were calculated. The most sensitive direct signs of gastric volvulus were an antropyloric transition point without any abnormality at the transition zone and the antrum at the same level or higher than the fundus. The presence of both these two findings as diagnostic criteria of gastric volvulus had 100 % sensitivity and specificity for the diagnosis of gastric volvulus. There was no association between CT signs of ischemia and final bowel ischemia at pathology. CT is both highly sensitive and specific for diagnosing acute gastric volvulus. (orig.)

    A 55-year-old wheelchair-bound woman with severe cerebral palsy was found at autopsy to have marked distention of the stomach due to a volvulus. The stomach was viable, and filled with air and fluid and had pushed the left dome of the diaphragm upwards causing marked compression of the left lung with a mediastinal shift to the right (including the heart). There was no evidence of gastric perforation, ischaemic necrosis or peritonitis. Removal of the organ block revealed marked kyphoscoliosis. Histology confirmed the viability of the stomach and biochemistry showed no dehydration. Death in cases of acute gastric volvulus usually occurs because of compromise of the gastric blood supply resulting in ischaemic necrosis with distention from swallowed air and fluid resulting in perforation with lethal peritonitis. Hypovolaemic shock may also occur. However, the current case demonstrates an alternative lethal mechanism, that of respiratory compromise due to marked thoracic organ compression.

    The integral search for improved living conditions for those patients with gastric cancer who have not received curative surgical treatment continues to challenge the knowledge, dexterity and ethical foundations of medical teams. The justification for palliative treatment must be based on a thorough consideration of the available options and the particular situation in each case. This article reviews endoscopic therapy with auto expandable prosthetics for palliative treatment of gastric cancer, as well as the scientific evidence that supports its use and the factors that determine its indication.

    The authors devised a novel method to automate the analysis of nuclear gastric emptying studies. Many previous methods have been used to measure gastric emptying but, are cumbersome and require continuing interference by the operator to use. Two specific problems that occur are related to patient movement between images and changes in the location of the radioactive material within the stomach. Their method can be used with either dual or single phase studies. For dual phase studies the authors use In-111 labeled water and Tc-99MSC (Sulfur Colloid) labeled scrambled eggs. For single phase studies either the liquid or solid phase material is used

    Forty two cases of gastric cancers were reviewed. The cancer had been examined by CT and was confirmed by operation and pathology. The diagnostic results of gastric cancers obtained by CT were compared with that from GI and fibro-gastroscopy examination. The results showed that the preparation of gastrointestinal tract before CT examination was important in the CT diagnosis of gastric cancer. CT in diagnosis of focus of gastric cancer and organ invasion is better than Gl and Fibro-gastroscopy and accuracy in diagnosis of gastric cancers is near to that of GI examination

    Smooth muscle tumors of stomach are unusual tumors, accounting for 1-3% of primary gastric malignancies. Diagnosis of these tumors is important because of the more favorable prognosis of this tumor than that of gastric carcinoma. A retrospective study was made in 18 patients who had pathology-proven gastric leiomyoma and leiomyosarcoma to identify radiologic characteristics for recent 6 years from Jan. 1978 to July. 1984 at Department of Radiology, Seoul National University Hospital. The results were as follows: 1. Age of 13 cases of gastric leiomyosarcoma ranged from 36 to 70 with average of 51 and the male to female ratio was 10 ; 3. Age of 5 cases of gastric leiomyoma ranged from 24 to 67 with average of 44 and the male to female ratio was 3 : 2. 2. Clinically, gastric leiomyosarcoma had epigastric pain in 7 cases, palpable mass in 4 cases, melena in 3 cases, haematemesis in 2 cases, 5 cases of gastric leiomyoma also had above symptoms respectively. 3. Of the 13 cases of gastric leiomyosarcoma studied by upper gastrointestinal examination, 6 cases (32%) involved the fundus, 10 cases (50%) in the body, 3 cases (18%) in the antrum. Of the 5 cases of gastric leiomyoma, 4 cases were confined to the fundus and 1 case in the body. 4. The size of the 13 gastric leiomyosarcoma ranged from 5 to more than 20 cm in diameter. The size of the 5 gastric leiomyomas ranged from 3 to 9 cm in diameter. 5. The growth type of gastric leiomysarcoma was exophytic in 8 cases, endogastric in 1 case and mixed pattern in 4 cases. The growth type of gastric leiomyoma were exophytic in 1 case, endogastric in 2 cases and mixed in 2 cases. 6. Mucosal pattern of gastric leiomyosarcoma were mainly effaced pattern in 10 cases (77%), but 3 cases (23%) showed irregular destruction. 1 case of gastric leiomyoma showed mucosal irregularity. 7.

  17. Scintigraphic evaluation of gastric emptying and motility

    International Nuclear Information System (INIS)

    Linke, R.

    2003-01-01

    The stomach consists of two functionally distinct parts. The fundus and upper corpus mainly serve as a reservoir and exert primarily a tonic activity, which presses ingesta towards the antrum and duodenum. The phasic contractility of the lower corpus and antrum cause mechanical breakdown and mixing of the food particels. A complex regulation of these mechanisms provides a regular gastric emptying. Various disorders such as diabetes mellitus, mixed connective tissue diseases, gastritis, tumors, dyspeptic disorders but also drugs and gastric surgery may influence or impair gastric function and may cause typical symptoms such as upper abdominal discomfort, bloating, nausea and vomiting. However, the interpretation of gastrointestinal symptoms often is difficult. Radionuclide studies of gastric emptying and motility are the most physiologic tools available for studying gastric motor function. Gastric scintigraphy is non-invasive, uses physiologic meal and is quantitative. Emptying curves generated from the gastric ROI offer information whether a disorder is accompanied by a regular, fast or slow gastric emptying. Data on gastric contractions (amplitude and frequency) provide additional information to results obtained by conventional emptying studies. Depending on the underlying disorder, gastric emptying and peristalsis showed both corresponding and discrepant findings. Therefore, both parameters should be routinely assessed to further improve characterisation of gastric dysfunction by scintigraphy. (orig.) [de

    At present, biopsy specimens, cancer cell lines and tissues obtained by gastric surgery are used in the study and analysis of gastric cancer, including the molecular mechanisms and proteomics. However, fibroblasts and other tissue components may interfere with these techniques. Therefore, the present study aimed to develop a procedure for the isolation of viable human gastric epithelial cells from gastric surgical tissues. A method was developed to culture human gastric epithelial cells using fresh, surgically excised tissues and was evaluated using immunocytochemistry, periodic acid-Schiff (PAS) staining and cell viability assays. Low cell growth was observed surrounding the gastric tissue on the seventh day of tissue explant culture. Cell growth subsequently increased, and at 12 days post-explant a high number of pure epithelial cells were detected. The gastric cancer cells exhibited rapid growth with a doubling time of 13-52 h, as compared to normal cells, which had a doubling time of 20-53 h. Immunocytochemical analyses of primary gastric cells revealed positive staining for cytokeratin 18 and 19, which indicated that the culture was comprised of pure epithelial cells and contained no fibroblasts. Furthermore, PAS staining demonstrated that the cultured gastric cells produced neutral mucin. Granulin and carbohydrate antigen 724 staining confirmed the purity of gastric cancer and normal cells in culture. This method of cell culture indicated that the gastric cells in primary culture consisted of mucin-secreting gastric epithelial cells, which may be useful for the study of gastric infection with Helicobacter pylori and gastric cancer.

  19. Localization of ectopic gastric mucosa by scintigraphy

    1988-01-01

    When gastric mucosal tissue occurs outside of the confines of the stomach, it is termed ectopic or heterotopic. Ectopic gastric mucosa may be found within Meckel's diverticulum, duplications of the alimentary tract, and Barrett's esophagus. In addition, a surgeon may inadvertently leave behind antral gastric mucosa while performing a partial gastrectomy for peptic ulcer disease (i.e., retained gastric antrum). It is important to detect the presence and location of ectopic mucosa because acid and pepsin secretion may cause ulceration in the adjacent tissue resulting in serious complications. The only currently available specific diagnostic technique for detecting ectopic gastric mucosa is pertechnetate Tc 99m (TcO 4- ) scintigraphy. This chapter reviews the functional anatomy of gastric mucosa, the mechanism of TcO 4 - localization, the various entities containing ectopic gastric mucosa, and the methods and results of TcO 4 - scanning for these disorders

    In recent 5 years, we have experienced 24 cases of advanced gastric cancer associated with obstructive uropathy. Included were 19 cases of undifferentiated, 3 cases of differentiated and 2 cases of unknown histological type. Obstructive uropathy is diagnosed based on the typical radiological findings such as dilatation and delayed demonstration of the upper collecting systems. Pathologically, undifferentiated type of gastric cancer had tendency to spread infiltratively along the vessels, nerves and the lymphatics without alteration of the ordinary anatomical structures. In such cases, mucosal surface of the urinary tract tended to be spared in spite of extensive tumor invasion. It was proven that several radiological findings were characteristic of urinary tract involvement secondary to gastric cancer. Either thread-like ureteral stricture by IVU or ring-like appearance of the ureter by CT is one of those typical findings. Renal sinus involvement may occur continuously to diffuse retroperitoneal invasion and it appears as a thickened wall of renal pelvis or soft tissue mass directly extending into the fatty tissue of renal sinus by CT. In such cases IVU has less diagnostic ability because of the lack of mucosal destruction. If the urinary bladder is involved, it typically shows chestnut-bur appearance by IVU and diffuse wall thickening by CT. In cases of advanced gastric cancer, particularly in cases of histologically undifferentiated type, CT and IVU images should be carefully interpreted in consideration of the infiltrative part of tumor extention.

    Epidemiological investigations indicated association of the Helicobacter pylori infections with the occurrence of inflammatory conditions of the gastric mucosa and development of chronic gastritis and intestinal type of gastric cancer. IL1A and IL1B genes have been proposed as key factors in determining risk of gastritis and malignant transformation. The aim of this paper was to evaluate association of interleukin-1 gene polymorphisms with chronic gastritis, atrophy, intestinal metaplasia, dysplasia and intestinal type of gastric cancer in H. pylori-infected patients. Patients subjected to analysis represent group of 144 consecutive cases that suffered from dyspepsia with coexisting infection of H. pylori and chronic gastritis, chronic atrophic gastritis, intestinal metaplasia, dysplasia or gastric cancer. Molecular studies involved analysis of -889C>T polymorphism of IL1A gene and +3954C>T polymorphism of IL1B gene. Statistical analysis of association of polymorphism -889C>T of gene IL1A with changes in gastric mucosa showed lack of significance, whereas +3954C>T polymorphism of IL1B gene showed significant association. Frequency of allele T of +3954C>T polymorphism of IL1B gene was higher in group of patients with chronic gastritis, atrophy, intestinal metaplasia, dysplasia or intestinal type of gastric cancer (32.1 %) as compared with population group (23 %), χ(2) = 4.61 and p = 0.03. This corresponds to odds ratio: 1.58, 95 % CI: 1.04-2.4. Our results indicate that +3954C>T polymorphism of IL1B gene increase susceptibility to inflammatory response of gastric mucosa H. pylori-infected patients and plays a significant role in the development of chronic gastritis, atrophy, intestinal metaplasia, dysplasia and the initiation of carcinogenesis.

    pearl millet (pennisetum glaucum L.) is a source of carbohydrate, protein and minerals that is comparable to other common cereal grains. However, anti nutrient factors like phytate and polyphenols reduce nutrient bioavailability which can be improved by suitable processing methods such as germination and fermentation with and without malt pretreatment. In this study of 8 pearl millet cultivars Ashana, Dahabaya, Dembi, GB-87-35, Kordofani, Madelkawaya, population 1Shambat and Ugandi were investigated. Results showed that pearl millet contained 7.7-8.9% moisture, 1.6-23% ash, 11.4-13.0% protein, 4.0-7.7% oil and 2.1-3.2% crude fiber. Mineral contents were 13.0-19.4, 370.0-547.5, 70.3-93.3, 49.1-61.9 and 551.0-1290.4 mg/100 g for Na,K,Mg, Ca and P respectively and 1.3-1.8, 7.5-11.7, 0.8-1.7, 0.5-1.5 and 0.062-0.103 mg/100 g for Zn, Fe, Mn, Cu and Co respectively. HCI-extractability of these minerals (an index of their bioavailability to humans) were 63.1-73.3% Na, 64.9-73.3% K, 55.7-61.4% mg, 27.7-88.3% Ca, 31.0-38.5% P, 41.2-45.9% Zn, 22.5-27.7% Fe, 44.3-48.8% Mn, 21.3-28.6% Cu and 85.3-88.6% CO. Phytic acid content ranged from 422.3-1101.0 mg/100 g and polyphenol ranged from 306.7-669.4 mg/100 g. Cooking caused slight increase in mineral content and significantly (p<0.01) improved the bioavailability of all the minerals investigated; phytic acid reduced by 6-10% and polyphenols by 6-8%. Germination for 2,4 and 6- days showed significant (P<0.01) differences in the concentration of minerals during the course of germination.Total content of Fe, Zn and Mn were increased significantly (P<0.01) for all cultivars. The bioavailability of all the minerals was significantly (P<0.01) improved throughout all the time intervals of germination. Phytic acid was reduced by 66.3-81.0% after 6- days of germination while polyphenol content was reduced by 34.3-44.0%. Fermentation of cultivars of : Ashana and Dembi affected the minerals content and significantly (P<0.01) improved the

    The objective of this study was to determine the efficiency of rye and barley starch hydrolysis in mashing processes using cereal malts as a source of amylolytic enzymes and starch, and to establish the volatile profile of the obtained agricultural distillates. In addition, the effects of the pretreatment method of unmalted cereal grains on the physicochemical composition of the prepared mashes, fermentation results, and the composition of the obtained distillates were investigated. The raw materials used were unmalted rye and barley grains, as well as the corresponding malts. All experiments were first performed on a semi-technical scale, and then verified under industrial conditions in a Polish distillery. The fermentable sugars present in sweet mashes mostly consisted of maltose, followed by glucose and maltotriose. Pressure-thermal treatment of unmalted cereals, and especially rye grains, resulted in higher ethanol content in mashes in comparison with samples subjected to pressureless liberation of starch. All agricultural distillates originating from mashes containing rye and barley grains and the corresponding malts were characterized by low concentrations of undesirable compounds, such as acetaldehyde and methanol. The distillates obtained under industrial conditions contained lower concentrations of higher alcohols (apart from 1-propanol) than those obtained on a semi-technical scale.

    The results of the studies of the decay of thallium isotopes establish the coexistence and crossing of two bands in the mercury isotopes. The two bands are built on states of different deformation. The band built upon the ground state has an associated small negative β value (oblate shape) while the second band has a large positive β value (prolate shape). The band heads for the deformed bands in the 184 186 188 Hg isotopes are established as 0 + levels at 375.2, 523.8, and 824.5 keV respectively. A comparison between the experimental results and the predictions of calculations based upon the coexistence of two different nuclear deformations has been made. The presence of two different deformations as described by two minima in the nuclear potential energy curve is termed ''shape coexistence.'' The good agreement of the calculations with the experimental results adds further support to the coexistence interpretation. The coexistence and crossing of two bands of different deformation explains the unusual behavior of the yrast level spacing that is referred to as 'backbending' when discussing moment of inertia versus rotational frequency plots based on the yrast levels. The studies of the 186 188 Pt levels have established the lower members of the ground state band and of a rotation-alignment band. The experimental results confirm the rotation-alignment explanation of backbending in the platinum cases discussed. (Auth.)

    Full Text Available Duodenal obstruction due to duodenal atresia occurs in 1 in 10,000 live births and is the most common type of intestinal obstruction in neonates [1–3]. Gastric outlet obstruction in the newborn period from causes other than hypertrophic pyloric stenosis is very uncommon [3]. Potential etiologies include gastric volvulus, antral web, and duplication cysts. Gastric diverticula in the infant is even more rare, with only a few case reports published, and only one describes a gastric diverticulum in the presence of a duodenal atresia [4–8]. In this report, we describe the first case of a gastric outlet obstruction due to a gastric diverticulum in the presence of duodenal atresia.

    Full Text Available A água de umidificação de malte, resultante da moagem úmida, pode ser usada como matéria prima na fabricação de cerveja. Há, entretanto, cervejarias que descartam esse subproduto, e conseqüentemente, o extrato nele contido. Em função disso, o presente trabalho teve por objetivo avaliar a possibilidade de ganho de rendimento na mosturação e alterações nas características químicas e sensoriais da bebida, em virtude do uso dessa água. Cervejas do tipo Pilsen foram produzidas de duas formas: com e sem água de umidificação de malte. Utilizou-se como matéria prima malte, lúpulo, xarope de maltose, água destilada e água de umidificação de malte. O mosto foi produzido pelo processo de infusão, separado do bagaço de malte por filtração convencional e fervido durante 60 minutos. Após seu resfriamento e clarificação o mosto foi inoculado com levedura de baixa fermentação (1,3g/l, ps e colocado para fermentar a 10°C. A fermentação foi encerrada com 90% da atenuação limite. Em seguida, a cerveja foi engarrafada e maturada a 0°C por 14 dias. Os resultados mostraram que o aumento do rendimento de mosturação, em função do uso da água de umidificação de malte, foi estatisticamente não significativo. A utilização dessa água praticamente não alterou as características químicas e sensoriais da cerveja, havendo apenas um leve aumento na intensidade de cor da bebida (7,1 x 8,0 EBC. Considerando, no entanto, que a água de umidificação de malte obtida em nível industrial apresenta maior concentração de extrato em relação àquela produzida em laboratório, espera-se que o uso da primeira traga ganho de rendimento industrial sem alterações significativas nas características da cerveja.The wet milling malt steep water can be used as raw material on brewing. However, some breweries discard this water containing a certain amount of extract. Based on this fact, the aim of this work was to evaluate possible

    The paper shows the potentialities of gastric study by magnetic resonance imaging (MRI). The methodic aspects of gastric study have been worked out. The MRI-semiotics of the unchanged and tumor-affected wall of the stomach and techniques in examining patients with gastric cancer of various sites are described. Using the developed procedure, MRI was performed in 199 patients, including 154 patients with gastric pathology and 45 control individuals who had no altered gastric wall. Great emphasis is placed on the role of MRI in the diagnosis of endophytic (diffuse) gastric cancer that is of priority value in its morphological structure. MRI was found to play a role in the diagnosis of the spread of a tumorous process both along the walls of the stomach and to its adjacent anatomic structures.

    Gastric and esophageal emptying were evaluated in 31 obese patients and 31 control subjects. A double-isotope techniques was used to measure gastric emptying of a mixed solid/liquid meal, and esophageal emptying was measured as the time taken for a bolus of the solid meal to enter the stomach. Gastric emptying of the solid and the liquid meal and esophageal emptying were delayed in the obese patients compared with the control subjects. There were no significant relationships among gastric emptying, esophageal emptying, and upper gastrointestinal symptoms in the obese patients alone. However, in the total group of 62 subjects there were significant correlations between body mass index and both gastric and esophageal emptying. These results indicate that delayed gastric and esophageal emptying occurs frequently in obesity and that these abnormalties relate to body weight.

  3. Beyond peaceful coexistence the emergence of space, time and quantum

    2016-01-01

    Beyond Peaceful Coexistence: The Emergence of Space, Time and Quantum brings together leading academics in mathematics and physics to address going beyond the 'peaceful coexistence' of space-time descriptions (local and continuous ones) and quantum events (discrete and non-commutative ones). Formidable challenges waiting beyond the Standard Model require a new semantic consistency within the theories in order to build new ways of understanding, working and relating to them. The original A. Shimony meaning of the peaceful coexistence (the collapse postulate and non-locality) appear to be just the tip of the iceberg in relation to more serious fundamental issues across physics as a whole.Chapters in this book present perspectives on emergent, discrete, geometrodynamic and topological approaches, as well as a new interpretative spectrum of quantum theories after Copenhagen, discrete time theories, time-less approaches and 'super-fluid' pictures of space-time.As well as stimulating further research among establis...

    The temperature dependence of thermal expansion of coexistence of ferromag-netism and superconductivity below the superconducting transition temperature T cu of a majority spin conduction band is investigated. Majority spin and minority spin superconducting gaps exist in the coexistent state. We assume that the Curie temperature is much larger than the superconducting transition temperatures. The free energy that Linder et al. [Phys. Rev. B76, 054511 (2007)] derived is used. The thermal expansion of coexistence of ferromagnetism and superconductivity is derived by the application of the method of Takahashi and Nakano [J. Phys.: Condens. Matter 18, 521 (2006)]. We find that we have the anomalies of the thermal expansion in the vicinity of the superconducting transition temperatures.

    Natural and supernatural explanations are used to interpret the same events in a number of predictable and universal ways. Yet little is known about how variation in diverse cultural ecologies influences how people integrate natural and supernatural explanations. Here, we examine explanatory coexistence in three existentially arousing domains of human thought: illness, death, and human origins using qualitative data from interviews conducted in Tanna, Vanuatu. Vanuatu, a Melanesian archipelago, provides a cultural context ideal for examining variation in explanatory coexistence due to the lack of industrialization and the relatively recent introduction of Christianity and Western education. We argue for the integration of interdisciplinary methodologies from cognitive science and anthropology to inform research on explanatory coexistence.

    Full Text Available Appendiceal mucocele is a rare clinical entity, which is however quite often associated with mucinous ovarian tumor. The coexistence of mucinous cystadenoma of the appendix and endometrial adenocarcinoma has not been reported before. A 49-year-old woman presented to our clinic with postmenopausal bleeding and no other symptom. Endometrial biopsy revealed endometrial adenocarcinoma of endometrioid type (grade I. Preoperative CT scanning revealed an appendiceal mucocele, and a colonoscopy confirmed the diagnosis. The patient underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy and appendectomy. The final histopathological examination showed a mucinous cystadenoma of the appendix and confirmed the diagnosis of endometrioid endometrial adenocarcinoma. The coexistence of appendiceal mucocele and female genital tract pathology is rare. However, gynecologists should keep a high level of suspicion for such possible coexistence. Both the diagnostic approach and the therapeutic management should be multidisciplinary, most importantly with the involvement of general surgeons.

    Equine gastric ulcer syndrome is one of the most frequently reported diseases in thoroughbred racehorses. Although several risk factors for the development of gastric ulcers have been widely studied, investigation of microbiological factors has been limited. In this study, the presence of Helicobacter spp. and the gastric microbial communities of thoroughbred racehorses having mild to severe gastric ulcers were investigated. Although Helicobacter spp. were not detected using culture and PCR techniques from 52 gastric biopsies and 52 fecal samples, the genomic sequences of H. pylori and H. ganmani were detected using nextgeneration sequencing techniques from 2 out of 10 representative gastric samples. The gastric microbiota of horses was mainly composed of Firmicutes (50.0%), Proteobacteria (18.7%), Bacteroidetes (14.4%), and Actinobacteria (9.7%), but the proportion of each phylum varied among samples. There was no major difference in microbial composition among samples having mild to severe gastric ulcers. Using phylogenetic analysis, three distinct clusters were observed, and one cluster differed from the other two clusters in the frequency of feeding, amount of water consumption, and type of bedding. To the best of our knowledge, this is the first study to investigate the gastric microbiota of thoroughbred racehorses having gastric ulcer and to evaluate the microbial diversity in relation to the severity of gastric ulcer and management factors. This study is important for further exploration of the gastric microbiota in racehorses and is ultimately applicable to improving animal and human health.

    A case of CT demonstration of a bleeding gastric ulcer is presented, in a patient with confusing clinical manifestations. Abdominal CT was performed without oral contrast medium administration, and showed extravasation of intravenous contrast into a gastric lumen distended with material of mixed attenuation. It is postulated that if radiopaque oral contrast had been given, peptic ulcer bleeding would probably have been masked. CT demonstration of gastric ulcer bleeding, may be of value in cases of differential diagnostic dilemmas.

    A case of CT demonstration of a bleeding gastric ulcer is presented, in a patient with confusing clinical manifestations. Abdominal CT was performed without oral contrast medium administration, and showed extravasation of intravenous contrast into a gastric lumen distended with material of mixed attenuation. It is postulated that if radiopaque oral contrast had been given, peptic ulcer bleeding would probably have been masked. CT demonstration of gastric ulcer bleeding, may be of value in cases of differential diagnostic dilemmas

    Gut hormone secretion in response to nutrient ingestion appears to depend on membrane proteins expressed by the enteroendocrine cells. These include transporters (glucose and amino acid transporters), and, in this case, hormone secretion depends on metabolic and electrophysiological events elicited...... that determines hormone responses. It follows that operations that change intestinal exposure to and absorption of nutrients, such as gastric bypass operations, also change hormone secretion. This results in exaggerated increases in the secretion of particularly the distal small intestinal hormones, GLP-1, GLP-2......, oxyntomodulin, neurotensin and peptide YY (PYY). However, some proximal hormones also show changes probably reflecting that the distribution of these hormones is not restricted to the bypassed segments of the gut. Thus, cholecystokinin responses are increased, whereas gastric inhibitory polypeptide responses...

  14. Radiation therapy for gastric cancer

    1988-01-01

    Adenocarcinoma of the stomach is a moderately radioresponsive neoplasm. Attempts to treat patients with unresectable disease with external beam radiation therapy alone have generally failed because of problems with tumor localization and adequate dose delivery as well as the inherent radioresponsiveness of the gastric mucosa and the organs intimately related to the stomach. Combining external beam therapy and chemotherapy (acting as a systemic agent and as a radiosensitizer) seems to be of some (albeit limited) benefit in the management of unresectable adenocarcinoma of the stomach. Optimum combinations of radiation therapy, chemotherapy, and radiation sensitizers in this situation remain to be determined. The authors discuss strides which have been made in the treatment of gastric cancer. They also address the unanswered clinical questions which remain regarding the use of radiation therapy in the treatment of this highly lethal disease

    A total of 136 cases with gastric cancer was treated with radiation and some anti-cancer drugs. The tumor responded markedly to radiation in 37% of 92 cases, irradiated more than 5000 rad and regressed completely in only 5% of them. Out of them, the permanent cure was achieved in 3% of T2-4 M0 cases. Serious complications, such as hemorrhagic gastritis, massive bleeding, chronic ulcer of the stomach and perforation, were also observed in a few per cent of them. It was suggested that in the treatment of inoperable gastric cancer, the combination treatment of radiation and chemotherapy should be chosen as a valuable therapeutic procedure to get a good palliation.

    Full Text Available An eight year old female dog was referred with anorexia, nervousness and emaciation. At the point of time, severe lifelessness was the only symptom. Then euthanasia was done according to the owner’s decision. As a result of postmortem examination, thin white matters were found on the gastric mucosa of the greater curvature and there were no other significant gross findings. Tissue specimens were collected from the gastric wall, esophagus, gall bladder, aorta, heart, kidneys, liver, mesenteric lymph node, lungs, urinary bladder and spleen and processed for histopathology. Microscopically, the masses of stomach were consisted of well-differentiated osteoid tissues, the compact bone-osteocytes and the matured lamellated bone with Haversian system. It was diagnosed as osteoma of the stomach. Other organs were free on such histological findings.

    Although the idea that gastric problems are in some way related to mental activity dates back to the beginning of the last century, until now it has received scant attention by physiologists, general practitioners and gastroenterologists. The major breakthrough in understanding the interactions between the central nervous system and the gut was the discovery of the enteric nervous system (ENS) in the 19th century. ENS (also called 'little brain') plays a crucial role in the regulation of the physiological gut functions. Furthermore, the identification of corticotropin-releasing factor (CRF) and the development of specific CRF receptor antagonists have permitted to characterize the neurochemical basis of the stress response. The neurobiological response to stress in mammals involves three key mechanisms: (1) stress is perceived and processed by higher brain centers; (2) the brain mounts a neuroendocrine response by way of the hypothalamic-pituitary-adrenal axis (HPA) and the autonomic nervous system (ANS), and (3) the brain triggers feedback mechanisms by HPA and ANS stimulation to restore homeostasis. Various stressors such as anger, fear, painful stimuli, as well as life or social learning experiences affect both the individual's physiologic and gastric function, revealing a two-way interaction between brain and stomach. There is overwhelming experimental and clinical evidence that stress influences gastric function, thereby outlining the pathogenesis of gastric diseases such as functional dyspepsia, gastroesophageal reflux disease and peptic ulcer disease. A better understanding of the role of pathological stressors in the modulation of disease activity may have important pathogenetic and therapeutic implications. © 2014 S. Karger AG, Basel.

    The changes on the molecular weight distribution (MWD) and particle size distribution (PSD) during hydrolysis of barley malt in isothermal mashing procedures were determined using asymmetrical flow field flow fractionation coupled to multiangle laser light scattering and refractive index (AF4/MALS/RI). Mash/trials were focused on amylolytic starch degradation. Therefore, temperatures (65, 70, and 75 °C) were selected according to α- and β-amylases range of activity. Samples were produced by triplicate, tracking amylolytic processes over time periods from 10 to 90 min in each mash/trial. AF4/MALS/RI analysis demonstrated significant differences on the values of the MWD and PSD according to the temperature/time profile used. At mashing times over 30 min at a temperature of 65 °C, when α- and β-amylase are both active, the decrease over time of the MWD and PSD was significantly higher (P < 0.005) than at 70 °C when mainly α-amylase is active. At 75 °C, also the activity of α-amylase decreased and the MWD and PSD were significantly lower (P < 0.005) than at 70 or 65 °C at any time of the procedure. The MWD and PSD of beer components influence beer palate fullness, thus AF4/ MALS/RI would be a powerful tool for breweries to adapt their technological processes to obtain beers with particular sensorial attributes. © 2017 Institute of Food Technologists®.

    In this study, conducted for three years on eleven malting barley varieties cultivated in central Italy, the incidence of different mycotoxigenic fungal genera, the identification of the Fusarium species associated with the Fusarium Head Blight (FHB) complex, and kernels contamination with deoxynivalenol (DON) and T-2 mycotoxins were determined. The influence of climatic conditions on Fusarium infections and FHB complex composition was also investigated. Fusarium species were always present in the three years and the high average and maximum temperatures during anthesis mainly favored their occurrence. The FHB complex was subject to changes during the three years and the main causal agents were F. poae, F. avenaceum, F. tricinctum and F. graminearum, which, even if constantly present, never represented the principal FHB agent. The relative incidence of Fusarium species changed because of climatic conditions occurring during the seasons. The FHB complex was composed of many different Fusarium species and some of them were associated with a specific variety and/or with specific weather parameters, indicating that the interaction between a certain plant genotype and climatic conditions may influence the presence of Fusarium spp. causing infections. With regard to mycotoxin contamination, T-2 toxin, in some cases, was found in kernels at levels that exceeded EU recommended values. PMID:28353653

    Full Text Available Pancreatic and gastric heterotopias are rare clinical entities which have been identified throughout the entire length of the gastrointestinal tract. Combined gastric and pancreatic heterotopias, although unusual, have been described in the duodenum and jejunum, and in other structures, including Meckel's diverticulum and the ampulla of Vater. We report a novel case of pancreatic and gastric heterotopia with an associated submucosal lipoma in a 38-year-old female with a recent history of rectal cancer and chronic crampy abdominal pain. On computed tomography, a 7-cm luminal polypoid mass extending into the distal ileum was discovered. The mass was successfully resected using retrograde double balloon enteroscopy. We believe this is the first report of all three histological entities co-existing in an obstructive ileal lesion in an adult. It highlights endoscopic resection trough double enteroscopy as a safe alternative to more invasive surgical approaches for this type of lesion.

    To investigate whether interdigestive gastric acid secretion can be controlled by a possible memory-related cortical mechanism. To evaluate gastric secretion in rats, we used a methodology that allows gastric juice collection in rats in their habitual conditions (without any restraining) by pairing sound as the conditioning stimulus (CS) and food as the unconditioning stimulus (US). The levels of gastric acid secretion under basal conditions and under sound stimulation were recorded and the circulating gastrin levels determined. When the gastric juice was collected in the course of the conditioning procedure, the results showed that under noise stimulation a significant increase in gastric acid secretion occurred after 10 days of conditioning (p<0.01). The significance was definitively demonstrated after 13 days of conditioning (p<0.001). Basal secretions of the conditioned rats reached a significant level after 16 days of conditioning. The levels of noise-stimulated gastric acid secretion were the highest so far described in physiological experiments carried out in rats and there were no significant increases in the circulating gastrin levels. The results point to the important role played by cortical structures in the control of interdigestive gastric acid secretion in rats. If this mechanism is also present in humans, it may be involved in diseases caused by inappropriate gastric acid secretion during the interprandial periods.

    Gastric cancer is one of the most common malignant tumors in digestive tract functional MRI can represent the functional changes of the tumor. DWI not only provides a new way to diagnosis the gastric cancer, but also reflect the pathology changes of the tumor, which has great value to predict the therapeutic effect and prognosis of the tumor. MRS is the only method to test the chemical composition of tissues in live without injury, which has great value in the early diagnosis of gastric tumor and in the research of tumor mechanism. This review is mainly focused on the status and development of functional MRI in gastric cancer. (authors)

    Gastric emptying scintigraphy was introduced more than 25 years ago by Grittith and still remains the gold standard to assess gastric emptying. Test meals, radiopharmaceuticals and acquisition procedures have been refined and optimized over the years and the test procedure is now pretty well standardized. However, in its most common use, gastric emptying scintigraphy provides little information on gastric physiology. Over the last decade, modelling of the liquid and solid emptying curves have brought some insight in the complex gastric physiology. Compartmental analysis of the stomach has also provided information on the pathophysiological mechanisms of delayed gastric emptying. Over the past 5 years, the most dramatic development in gastric emptying scintigraphy has been the introduction of Digital Antral Scintigraphy (DAS). Digital Antral scintigraphy basically consists in dynamically imaging of the stomach and the use of a refined Fourier transform processing method. This new procedure allows for the visualization of antral contractions and, alike manometry, permits quantitative characterization on the frequency and amplitude of these contractions. Overall, this new procedure provides a unique, non invasive tool to characterize gastric motility, to define the pathophysiologic mechanisms of gastric motor disorders and to evaluate the effect of new gastro-kinetic compounds.

    Analyzing coexistence and survival scenarios of Lotka-Volterra (LV) networks in which the total biomass is conserved is of vital importance for the characterization of long-term dynamics of ecological communities. Here, we introduce a classification scheme for coexistence scenarios in these conservative LV models and quantify the extinction process by employing the Pfaffian of the network’s interaction matrix. We illustrate our findings on global stability properties for general systems of four and five species and find a generalized scaling law for the extinction time.

    Objective: Gastric blunt traumatic injuries are uncommon and their radiological appearance has been infrequently reported in medical literature. These injuries are difficult to diagnose preoperatively, though they require immediate recognition to minimize their otherwise high mortality and morbidity. The aim of our study is to describe the radiological appearance of blunt gastric traumatic injuries. Materials and methods: Retrospective evaluation of a 25 patients series observed between January 1997 and May 2005. Results: We observed rupture of the stomach in 20% of cases, in 44% of cases a partial lesion of the stomach, in one case a necrotic post-traumatic volvulus, five patients (20%) had benign portal pneumatosis, in three patients the stomach was secondarily involved because of a diaphragmatic hernia. The fundus resulted to be the most frequently damaged part of the stomach (80%). Conclusions: Blunt traumatic injuries need a careful and systematic approach given their economical and social relevance. For these reasons uncommon lesions require attention and may be important to search for specific findings of gastric lesions

    Obesity is a public health problem, for which the prevalence has increased worldwide at an alarming rate, affecting 1.7 billion people in the world. To describe the technique employed in incomplete penetration of gastric band where endoscopic management and/or primary closure is not feasible. Laparoscopic removal of gastric band was performed in five patients with incomplete penetrance using Foley catheterization in the perforation site that could lead to the development of a gastro-cutaneous fistula. The cases presented include a leak that required surgical lavage with satisfactory outcome, and one patient developed stenosis 3 years after surgical management, which was resolved endoscopically. In all cases, the penetration site closed spontaneously. Gastric band erosion has been reported in 3.4% of cases. The reason for inserting a catheter is to create a controlled gastro-cutaneous fistula, allowing spontaneous closure. Various techniques have been described: the totally endoscopic, hybrid techniques (endoscopic/laparoscopic) and completely laparoscopic. A technique is described here that is useful and successful in cases where the above-described treatments are not viable. Copyright © 2015. Published by Masson Doyma México S.A.

    Although gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, they comprise less than 1% of all gastrointestinal tumors. Neuroendocrine tumors (NET) of the gastro-enteropancreatic system are also rare, representing about 2% of all gastrointestinal neoplasms. Pancreatic localization of NET is extremely uncommon-these tumors are only 1-5% of all pancreatic cancers. We describe an unusual case with triple tumor localization-a gastric tumor, a formation in the pancreas, which involves the retroperitoneal space, and a uterine leiomyoma. The exact diagnosis was confirmed with immunohistochemical study after surgical treatment of the patient. Distal pancreatic resection, splenectomy, partial gastrectomy, omentectomy, and hysterectomy were performed. The histological examination proved an epithelioid type of gastric GIST. Immunostaining showed focal positive expression of c-kit and no mitotic figures per 50 HPF. Histology of the pancreatic and retroperitoneal formation proved a well-differentiated NET with origin from the islets of Langerhans. The immunohistochemical study demonstrated co-expression of chromogranin A and synaptophysin. This is the fourth case published so far of a patient with synchronous pancreatic NET and gastric GIST. The main objective of the study is to present a unique case because we have not found any reports for coexistence of the described three types of neoplasm, as in our patient, and we hope that it will be valuable in the future investigations about the genesis, diagnosis, and treatment of these types of tumors.

    The aim of this study was to determine both the type of gastric mioelectric and emptying disorders in correlation to degree of severity of hyperthyroidism (clinical and thyroid hormones' blood levels) and ANS function estimated in HRV analysis. The study was performed on a group of 50 patients (35 with multinodular toxic goitre and 15 with Graves' disease, 45 females and 5 males, mean age 39.6 years, mean BMI 23.72) with newly diagnosed and so far untreated hyperthyroidism. The control group were 50 healthy volunteers age-, sex-, and BMI-matched to the studied group. Patients were studied twice, within newly diagnosed thyreotoxicosis and after treatment (Metizol) and reaching stable euthyroid state. The study consisted of: a) percutaneous EGG analysis (Synectics): 30 minutes before and after a test meal (ENRICH Liquid 250 ml), b) HRV analysis (ECG POSTER 2002): 10 minutes at rest and during deep breathing test, c) ultrasound measurement of gastric emptying by Bolondi method. Statistical analysis of collected data was performed. In hyperthyroid patients significant both preprandial and postprandial dysrhythmia (33.01% of bradygastria and 16.49% of tachygastria) was found. In some patients decrease of amplitude of EGG signal was marked as a result of antral hypomotility with coexisting significantly prolonged gastric emptying (110 min). Among severe hyperthyroid patients both the antral food distribution (antrum 35% bigger than in a control group) and impaired proximal stomach relaxation were evident. The degree of gastric mioelectric activity and emptying disorders was proportional to the degree of both severity of clinical manifestation of hyperthyroidism in Zgliczynski scale (from I degree to III degrees) and free thyroid hormones' blood levels (positive correlation). In HRV analysis at rest in hyperthyroid patients comparing to a control group the decrease of both the heart rate variability and a total power was found particularly in HF component resulting in

    Gastric scintigraphy is the gold standard for the measurement of the gastric emptying of a meal because of its reliability and its reproducibility and the respect of physiological conditions. Moreover, this technique allows to measure the emptying of solid and liquid phases simultaneously. Symptoms motivating a gastric scintigraphy, suggest either a gastric stasis (dyspepsia) or a gastric incontinence (dumping syndrome). The two most frequent clinical conditions triggering this test are motility disorders following vagotomy, a delayed emptying of solids is often associated to an accelerated emptying of liquids. Gastric scintigraphy proves quite useful in these conditions, since the diagnosis of such complex abnormalities is uneasy to establish exclusively on a clinical basis. In idiopathic dyspepsia, gastric stasis is proved only in 50 % of the patients. However, a radionuclide study of gastric emptying is seldom ordered because of the common character and good tolerance of these symptoms. In everyday practice, gastric scintigraphy is considered only when gastric or intestinal obstructive lesions have been ruled out. A suggestive clinical picture and/or absence of a deteriorated general condition allow to prescribe a symptomatic treatment. More rarely, equivocal symptoms, degradation of the general condition and unresponsiveness to symptomatic drugs call for gastric scintigraphy. (authors). 241 refs., 2 figs

    To assess gastric trocarization and orogastric tubing as a means of gastric decompression for the initial management of gastric dilatation-volvulus. Retrospective review of 116 gastric dilatation-volvulus cases from June 2001 to October 2009. Decompression was performed via orogastric tubing in 31 dogs, gastric trocarization in 39 dogs and a combination of both in 46 dogs. Tubing was successful in 59 (75·5%) dogs and unsuccessful in 18 (23·4%) dogs. Trocarization was successful in 73 (86%) dogs and unsuccessful in 12 (14%) dogs. No evidence of gastric perforation was noted at surgery in dogs undergoing either technique. One dog that underwent trocarization had a splenic laceration identified at surgery that did not require treatment. Oesophageal rupture or aspiration pneumonia was not identified in any dog during hospitalization. No statistical difference was found between the method of gastric decompression and gastric compromise requiring surgical intervention or survival to discharge. Orogastric tubing and gastric trocarization are associated with low complication and high success rates. Either technique is an acceptable method for gastric decompression in dogs with gastric dilatation-volvulus. © 2013 British Small Animal Veterinary Association.

    We demonstrate experimentally the feasibility of continuous variable quantum key distribution (CV-QKD) in dense-wavelength-division multiplexing networks (DWDM), where QKD will typically have to coexist with several co-propagating (forward or backward) C-band classical channels whose launch power is around 0 dBm. We have conducted experimental tests of the coexistence of CV-QKD multiplexed with an intense classical channel, for different input powers and different DWDM wavelengths. Over a 25 km fiber, a CV-QKD operated over the 1530.12 nm channel can tolerate the noise arising from up to 11.5 dBm classical channel at 1550.12 nm in the forward direction (9.7 dBm in backward). A positive key rate (0.49 kbits s −1 ) can be obtained at 75 km with classical channel power of respectively −3 and −9 dBm in forward and backward. Based on these measurements, we have also simulated the excess noise and optimized channel allocation for the integration of CV-QKD in some access networks. We have, for example, shown that CV-QKD could coexist with five pairs of channels (with nominal input powers: 2 dBm forward and 1 dBm backward) over a 25 km WDM-PON network. The obtained results demonstrate the outstanding capacity of CV-QKD to coexist with classical signals of realistic intensity in optical networks. (paper)

    Evolutionary biologists since Darwin have hypothesized that closely related species compete more intensely and are therefore less likely to coexist. However, recent theory posits that species diverge in two ways: either through the evolution of 'stabilizing differences' that promote coexistence by causing individuals to compete more strongly with conspecifics than individuals of other species, or through the evolution of 'fitness differences' that cause species to differ in competitive ability and lead to exclusion of the weaker competitor. We tested macroevolutionary patterns of divergence by competing pairs of annual plant species that differ in their phylogenetic relationships, and in whether they have historically occurred in the same region or different regions (sympatric versus allopatric occurrence). For sympatrically occurring species pairs, stabilizing differences rapidly increased with phylogenetic distance. However, fitness differences also increased with phylogenetic distance, resulting in coexistence outcomes that were unpredictable based on phylogenetic relationships. For allopatric species, stabilizing differences showed no trend with phylogenetic distance, whereas fitness differences increased, causing coexistence to become less likely among distant relatives. Our results illustrate the role of species' historical interactions in shaping how phylogenetic relationships structure competitive dynamics, and offer an explanation for the evolution of invasion potential of non-native species. © 2016 The Author(s).

  11. Interference Mitigation for Coexistence of Heterogeneous Ultra-Wideband Systems

    2006-01-01

    Full Text Available Two ultra-wideband (UWB specifications, that is, direct-sequence (DS UWB and multiband-orthogonal frequency division multiplexing (MB-OFDM UWB, have been proposed as the candidates of the IEEE 802.15.3a, competing for the standard of high-speed wireless personal area networks (WPAN. Due to the withdrawal of the standardization process, the two heterogeneous UWB technologies will coexist in the future commercial market. In this paper, we investigate the mutual interference of such coexistence scenarios by physical layer Monte Carlo simulations. The results reveal that the coexistence severely degrades the performance of both UWB systems. Moreover, such interference is asymmetric due to the heterogeneity of the two systems. Therefore, we propose the goodput-oriented utility-based transmit power control (GUTPC algorithm for interference mitigation. The feasible condition and the convergence property of GUTPC are investigated, and the choice of the coefficients is discussed for fairness and efficiency. Numerical results demonstrate that GUTPC improves the goodput of the coexisting systems effectively and fairly with saved power.

    This article reviews recent research about academic learning and school coexistence in adolescence from a gender perspective. It focuses on the research developed by the Preventive Psychology research group (UCM), specially the results from the Spanish National Study of School Coexistence using a sample of 22,247 secondary school students. Research shows that girls are overrepresented in positive indicators whereas boys are in negative indicators, not only in academic adjustment but also in school coexistence. Girls' better academic achievement can be explained by their higher tendency to overcome sexism: they identify with traditional masculinity values (such as success orientation) without giving up traditional femininity values (such as empathy). Based on this, the following conclusions are reached: 1) to extend the advantages of equality also to men; 2) to emphasize that sharing academic contexts and activities is necessary but sufficient to construct equality; and lastly, 3) to improve school coexistence, it is necessary to adopt a integrative gender approach to prevent any kind of violence, including violence against women.

    If a pluralistic democratic state such as the United States wishes to move beyond coexistence and toward a more reflective religious pluralism, then public schools must take epistemic issues seriously. Taking a cue from multicultural education, many have called for including the study of religion from a cultural perspective. I argue instead that,…

    Dynamics in coupled Duffing oscillators with two coexisting symmetrical attractors is investigated. For a pair of Duffing oscillators coupled linearly, the transition to the synchronization generally consists of two steps: Firstly, the two oscillators have to jump onto a same attractor, then they reach synchronization similarly to coupled monostable oscillators. The transition scenarios to the synchronization observed are strongly dependent on initial conditions. (general)

    The Hubbard model in the nearly half-filled case was studied in the mean field approximation using the effective Hamiltonian approach. Both antiferromagnetic order parameter and condensation of singlet pairs were considered. In certain parameter ranges the coexistence of antiferromagnetism and superconductivity is energetically favourable. Relevance to the high temperature superconductivity and other theoretical approaches is also discussed. (author). 10 refs, 3 figs
