    Occurrence of metastatic cancer to the stomach is rare, particularly in patients with prostate cancer. Gastric metastasis generally presents as a solitary and submucosal lesion with a central depression. We describe a case of gastric metastasis arising from prostate cancer, which is almost indistinguishable from the undifferentiated-type gastric cancer. A definitive diagnosis was not made until endoscopic resection. On performing both conventional and magnifying endoscopies, the lesion appeared to be slightly depressed and discolored area and it could not be distinguished from undifferentiated early gastric cancer. Biopsy from the lesion was negative for immunohistochemical staining of prostate-specific antigen, a sensitive and specific marker for prostate cancer. Thus, false initial diagnosis of an early primary gastric cancer was made and endoscopic submucosal dissection was performed. Pathological findings from the resected specimen aroused suspicion of a metastatic lesion. Consequently, immunostaining was performed. The lesion was positive for prostate-specific acid phosphatase and negative for prostate-specific antigen, cytokeratin 7, and cytokeratin 20. Accordingly, the final diagnosis was a metastatic gastric lesion originating from prostate cancer. In this patient, the definitive diagnosis as a metastatic lesion was difficult due to its unusual endoscopic appearance and the negative stain for prostate-specific antigen. We postulate that both of these are consequences of hormonal therapy against prostate cancer.

    Problems concerning diagnosis of early stomach cancer using X-ray and endoscopic investigation techniques are stated. Classification of early stomach cancer suggested by the Japan Endoscopy Society and division system of early stomach cancer into two main foms: depth (erosive-ulcerous) one and elevated (polypoid) one-is presented X-ray and endoscopic investigation techniques are shown to be high efficiency concerning revealingation of stomach mucous variations using biopsy, which allow to determine for certain whother the process is benign or malignant one

    Some potentialities of the X-ray and endoscopic methods in the recognition of early stomach cancer are analysed. Both methods are provided by a roentgenotogist. Of 396 operated patients with stomach cancer, early forms were detected in 78 which is equal to 8% of the detected number and 19.7% of the operated cancer pasients. Two macroscopic forms of early cancer were detected: cancer with ulceration (erosion-ulcerative form) and polypoidcancer. The first form is interpreted as primary-ulcerative cancer, malignant ulcers and cancer in the form of erosions, the second one as polyps, polypoid and patchlike cancer, malignant polyps. X-ray changes were detected in 80% of the patients, in the rest of 20% by the endoscopic method only. With the help of the roentgenological and endoscopic methods (without cytological examination) one cannot be sure of accurate differential diagnosis between malignant and benign variants of ulcerations and polypoid changes in early cancer. The potentialities of the X-ray method ir the detection of ulcerative and polypoid changes of the stomach make it possible to improve it, though under a strict condition of performing subsequent obligatory endoscopy and getting tissue specimens for biopsy. The organization of the common roentgenoendoscopic centers is found appropriate

    Little information exists regarding the optimal treatment of early gastric cancer (EGC) in a remnant stomach or gastric tube. The aim of this study was to assess the feasibility and clinical outcomes of endoscopic submucosal dissection (ESD) for EGC in a remnant stomach and gastric tube. Between September 2002 and December 2009, ESD was performed in 62 lesions in 59 patients with EGC in a remnant stomach (48 lesions) or gastric tube (14 lesions). Clinicopathological data were retrieved retrospectively to assess the en bloc resection rate, complications, and outcomes. Treatment results were assessed according to the indications for endoscopic resection, and were compared with those of ESD performed in a whole stomach during the same study period. The en bloc resection rates for lesions within the standard and expanded indication were 100 % and 93 %, respectively. Postoperative bleeding occurred in five patients (8 %). The perforation rate was significantly higher (18 %, 11 /62) than that of ESD in a whole stomach (5 %, 69 /1479). Among the perforation cases, eight lesions involved the anastomotic site or stump line, and ulcerative changes were observed in five lesions. The 3-year overall survival rate was 85 %, with eight deaths due to other causes and no deaths from gastric cancer. A high en bloc resection rate was achieved by ESD for EGC in a remnant stomach or gastric tube; however, this procedure is still technically demanding due to the high complication rate of perforation. © Georg Thieme Verlag KG Stuttgart · New York.

    Esophagus and stomach cancers are associated with poor prognosis. But most published population-based cancer survival estimates for stomach and esophagus cancer refer to survival experience of patients diagnosed in the 1990s or earlier years. The aim of this study was to provide up-to-date survival estimates and trends for patients with stomach and esophagus cancer in Germany. Our analysis is based on data from 11 population-based cancer registries, covering 33 million inhabitants. Patients diagnosed with stomach and esophagus cancer in 1997-2006 were included. Period analysis was used to derive five-year relative survival estimates and trends by age, sex, cancer subsite, and stage for the time period of 2002-2006. German and US survival estimates were compared utilizing the SEER 13 database. Overall age-standardized five-year relative survival was 31.8% and 18.3% for stomach and esophagus cancer, respectively, compared to 27.2% and 17.4% in the US. Survival was somewhat higher among female than among male patients for both cancer sites (33.6% vs. 30.6% and 21.5% vs. 17.5%, respectively) and much higher for non-cardia stomach cancer (40.4%) than for cardia cancer (23.4%). From 2002 to 2006, a moderate increase in five-year relative survival by 2.7 percent units was observed for non-cardia stomach cancer patients in Germany (p cancer survival has reached levels around 40% for patients with non-cardia stomach cancer in Germany in the early 21st century, whereas it remained at lower levels around 20% for patients with esophagus and cardia cancer.

    To elucidate the clinicopathological characteristics of clinically early gastric cancer in the upper-third stomach and to clarify treatment precautions. A total of 683 patients with clinical early gastric cancer were enrolled in this retrospective study, 128 of whom had gastric cancer in the upper-third stomach (U group). All patients underwent a double contrast barium examination, endoscopy, and computed tomography (CT), and were diagnosed preoperatively based on the findings obtained. The clinicopathological features of these patients were compared with those of patients with gastric cancer in the middle- and lower-third stomach (ML group). We also compared clinicopathological factors between accurate-diagnosis and under-diagnosis groups in order to identify factors affecting the accuracy of a preoperative diagnosis of tumor depth. Patients in the U group were older (P = 0.029), had a higher ratio of males to females (P = 0.015), and had more histologically differentiated tumors (P = 0.007) than patients in the ML group. A clinical under-diagnosis occurred in 57 out of 683 patients (8.3%), and was more frequent in the U group than in the ML group (16.4% vs 6.3%, P cancer recurrence was not detected in the U group in the present study. Clinical early gastric cancer in the upper-third stomach has distinguishable characteristics that increase the risk of a clinical under-diagnosis, especially in patients with larger or undifferentiated tumors.

    We report the case of a 45-year-old male patient who developed an acute peptic ulcer perforation of the tubal stomach on the second postoperative day after oesophagectomy. The patient underwent emergency surgery (perforation was closed with a Graham patch) followed by treatment in intensive care, and was finally discharged on the 19th postoperative day. Gastric pull-up is a surgical technique that is widely used to re-establish the continuity of the gastrointestinal tract after oesophagectomy. Various early and late complications of reconstruction with the tubal stomach are well-known, such as gastric necrosis, gastritis, gastric ulcer, as well as benign and malignant tumors. The precise etiology of gastric tube ulceration is not known yet, however, it can develop not only in the late, but also in the early postoperative period, as well.

    Laparoscopic proximal gastrectomy (LPG) has recently been applied for early gastric cancer (EGC) in the upper stomach as a minimally invasive and function-preserving surgery. This study aimed to clarify the feasibility and nutritional benefits of LPG over laparoscopic total gastrectomy (LTG). This was a retrospective study of 77 patients with clinical stage I gastric cancer in the upper stomach. Of these patients, 25 underwent LPG, while 52 underwent LTG. Surgical outcomes and postoperative nutritional status such as changes in body weight and blood chemistries were compared between LPG and LTG. Intraoperative blood loss and C-reactive protein levels at 3 and 7 days after surgery were significantly lower in LPG than in LTG (p = 0.018, 0.036, and 0.042, respectively). No significant differences were observed in postoperative early or late complication rates between LPG and LTG. The incidence of Los Angeles Grade B or more severe reflux esophagitis after LPG was 9.1 %, which was similar to that after LTG (9.3 %). Postoperative changes in body weight at 6 months and 1 and 2 years after surgery were consistently less in LPG than in LTG (p = 0.001, 0.022, and 0.001, respectively). Moreover, postoperative levels of hemoglobin and serum albumin and total lymphocyte count were also higher in LPG than in LTG. LPG may be a better choice for EGC in the upper stomach than LTG because it has distinct advantages in terms of surgical invasiveness and postoperative nutritional status.

    Endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) after surgical gastrectomy is a technically difficult procedure because of the limited working space in the remnant stomach as well as the presence of severe gastric fibrosis and staples under the suture line. We evaluated clinical results including long-term outcomes to determine the feasibility and effectiveness of ESD for EGC in the remnant stomach of patients after gastrectomy. Retrospective study. National Cancer Center Hospital, Tokyo, Japan. We investigated patients undergoing ESD for EGC in the remnant stomach from 1997 to 2011. We examined the patient characteristics, endoscopic findings, technical results, adverse events, and histopathologic results including curability and evaluations of Helicobacter pylori gastritis in addition to the rates of local recurrence, metachronous gastric cancer, overall survival, and cause-specific survival. A total of 128 consecutive patients with 139 lesions had previously undergone 87 distal (68%), 25 proximal (19.5%) and 16 pylorus-preserving gastrectomies (12.5%). The median period from the original gastrectomy to the subsequent ESD for EGC in the remnant stomach was 5.7 years (range 0.6-51 years), the median tumor size was 13 mm (range 1-60 mm), and the median procedure time was 60 minutes (range 15-310 minutes). There were 131 en bloc resections (94%), with curative resections achieved for 109 lesions (78%); 22 lesions (16%) resulted in non-curative resections, and 8 lesions (6%) had only a horizontal margin positive or had inconclusive results. A total of 118 patients (92%) were assessed as H pylori gastritis-positive, with 7 patients (5%) negative. Adverse events included 2 cases of delayed bleeding (1.4%) and 2 perforations (1.4%), with 1 patient requiring emergency surgery. The 5-year overall and cause-specific survival rates were 87.3% and 100%, respectively, during a median follow-up period of 4.5 years (range 0-13.7 years), with no deaths from

    Absence of a substantial pretracheophyte fossil record for bryophytes (otherwise predicted by molecular systematics) poses a major problem in our understanding of earliest land-plant structure. In contrast, there exist enigmatic Cambrian-Devonian microfossils (aggregations of tubes or sheets of cells or possibly a combination of both) controversially interpreted as an extinct group of early land plants known as nematophytes. We used an innovative approach to explore these issues: comparison of tube and cell-sheet microfossils with experimentally degraded modern liverworts as analogues of ancient early land plants. Lower epidermal surface tissues, including rhizoids, of Marchantia polymorpha and Conocephalum conicum were resistant to breakdown after rotting for extended periods or high-temperature acid treatment (acetolysis), suggesting fossilization potential. Cell-sheet and rhizoid remains occurred separately or together depending on the degree of body degradation. Rhizoid break-off at the lower epidermal surface left rimmed pores at the centers of cell rosettes; these were similar in structure, diameter, and distribution to pores characterizing nematophyte cell-sheet microfossils known as Cosmochlaina. The range of Marchantia rhizoid diameters overlapped that of Cosmochlaina pores. Approximately 14% of dry biomass of Marchantia vegetative thalli and 40% of gametangiophores was resistant to acetolysis. Pre- and posttreatment cell-wall autofluorescence suggested the presence of phenolic compounds that likely protect lower epidermal tissues from soil microbe attack and provide dimensional stability to gametangiophores. Our results suggest that at least some microfossils identified as nematophytes may be the remains of early marchantioid liverworts similar in some ways to modern Marchantia and Conocephalum.

    Roentgenological findings of the fine reliefs in the non-cancerous portion were studied in 61 patients with early gastric cancer by double contrast examination. Incidence of the various types of the fine reliefs in the non-cancerous portion were as follows ; verrucae 4 %, granularity 34 %, fine granularity 58 %, islet 24 %, network 17 % and irregular network 16 %, respectively. Fine granularity and network were observed in 61 % and 46 % of the cases with poorly differentiated adenocarcinoma, respectively. Granularity, fine granularity and irregular network were observed in 30 %, 55 % and 40 % of the cases with signet-ring cell carcinoma, respectively. Granularity, fine granularity and islet were observed in 41 %, 59 % and 30 % of the cases with tubular adenocarcinoma, respectively. These results suggest that fine reliefs in the non-cancerous portion of the stomach with early gastric cancer showed both findings those found in atrophic gastritis (verrucae, granularity, fine granularity and network) and those in gastric cancer (granularity, fine granularity, islet and irregular network).

    The Warburg effect is an abnormal glycolysis response that is associated with cancer cells. Here we present evidence that metabolic changes resembling the Warburg effect are induced by a nonmammalian virus. When shrimp were infected with white spot syndrome virus (WSSV), changes were induced in several metabolic pathways related to the mitochondria. At the viral genome replication stage (12 h postinfection [hpi]), glucose consumption and plasma lactate concentration were both increased in WSSV-infected shrimp, and the key enzyme of the pentose phosphate pathway, glucose-6-phosphate dehydrogenase (G6PDH), showed increased activity. We also found that at 12 hpi there was no alteration in the ADP/ATP ratio and that oxidative stress was lower than that in uninfected controls. All of these results are characteristic of the Warburg effect as it is present in mammals. There was also a significant decrease in triglyceride concentration starting at 12 hpi. At the late stage of the infection cycle (24 hpi), hemocytes of WSSV-infected shrimp showed several changes associated with cell death. These included the induction of mitochondrial membrane permeabilization (MMP), increased oxidative stress, decreased glucose consumption, and disrupted energy production. A previous study showed that WSSV infection led to upregulation of the voltage-dependent anion channel (VDAC), which is known to be involved in both the Warburg effect and MMP. Here we show that double-stranded RNA (dsRNA) silencing of the VDAC reduces WSSV-induced mortality and virion copy number. For these results, we hypothesize a model depicting the metabolic changes in host cells at the early and late stages of WSSV infection.

    Patients who die from stomach cancer are still present. Early diagnosis is crucial in reducing the mortality rate of cancer patients. Therefore, computer aided methods have been developed for early detection in this article. Stomach cancer images were obtained from Fırat University Medical Faculty Pathology Department. The Local Binary Patterns (LBP) and Histogram of Oriented Gradients (HOG) features of these images are calculated. At the same time, Sammon mapping, Stochastic Neighbor Embedding (SNE), Isomap, Classical multidimensional scaling (MDS), Local Linear Embedding (LLE), Linear Discriminant Analysis (LDA), t-Distributed Stochastic Neighbor Embedding (t-SNE), and Laplacian Eigenmaps methods are used for dimensional the reduction of the features. The high dimension of these features has been reduced to lower dimensions using dimensional reduction methods. Artificial neural networks (ANN) and Random Forest (RF) classifiers were used to classify stomach cancer images with these new lower feature sizes. New medical systems have developed to measure the effects of these dimensions by obtaining features in different dimensional with dimensional reduction methods. When all the methods developed are compared, it has been found that the best accuracy results are obtained with LBP_MDS_ANN and LBP_LLE_ANN methods.

    Proximal gastrectomy has two problems, reflux esophagitis and curability. This study evaluates postoperative outcomes focusing on reflux esophagitis and curability of proximal gastrectomy with jejunal pouch interposition for early gastric cancer in the upper third of the stomach. One hundred and thirty nine patients who underwent jejunal pouch interposition between 1996 and 2011, 10 esophago-gastrostomy and 20 jejunal interposition at our institution were compared retrospectively to examine heart burn and reflux esophagitis. Furthermore, we examined the remote outcomes of jejunal pouch interposition patients. There were significantly fewer cases of heart burn; the numbers of cases of reflux esophagitis based on endoscopic findings were significantly small in jejunal pouch interposition. Carcinoma of the remnant stomach after jejunal pouch interposition was observed in 9 patients, curative treatment was possible with endoscopic therapy in 6 patients and surgical treatment in 3 patients. There are 119 survivals and 20 deaths at present Death caused primary disease is only 2 patients. Both recurrent patterns were peritoneal metastasis and the histopathological diagnosis was not indicated for proximal gastrectomy. Jejunal pouch interposition after proximal gastrectomy for early upper third gastric cancer proves beneficial and favorable modality achieving prevention of reflux esophagitis and high curability.

    The feasibility, safety, and improved quality of postoperative life following laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG) with a hand-sewn anastomosis via a mini-laparotomy for early gastric cancer (EGC) have been previously established. Here we describe the surgical procedure of totally laparoscopic pylorus-preserving gastrectomy (TLPPG) using an intracorporeal delta-shaped anastomosis technique, and the short-term surgical outcomes of 60 patients with EGC in the middle stomach are reported. After lymphadenectomy and mobilization of the stomach, intraoperative gastroscopy was performed in order to verify the location of the tumor, and then the distal and proximal transecting lines were established, 5 cm from the pyloric ring and just proximal to Demel's line, respectively. Following transection of the stomach, a delta-shaped intracorporeal gastrogastrostomy was made with linear staplers. There were no intraoperative complications or conversions to open surgery. Mean operation time and blood loss were 259 min and 28 mL, respectively. Twelve patients (20.0%) experienced postoperative complications classified as grade II using the Clavien-Dindo classification, with the most frequent complication being gastric stasis (6 cases, 10.0 %). The incidence of severe complications classified as grade III or above was 1.7%; only one patient required reoperation and intensive care due to postoperative intraabdominal bleeding and subsequent multiple organ failure. TLPPG with an intracorporeal delta-shaped anastomosis was found to be a safe procedure, although it tended to require a longer operating time than the well-established LAPPG with a hand-sewn gastrogastrostomy.

Instead, their status as biologic structures and thus actual fossils is supported. Enrichment in the element carbon, and also possibly to some extent the elements magnesium and iron, seems to be playing some role in the preservation process.

    Xenografting is widely used for assessing in vivo pluripotency of human stem cell populations. Here, we report on early to late events in the development of mature experimental teratoma from a well-characterized human embryonic stem cell (HESC) line, HS181. The results show an embryonic process, increasingly chaotic. Active proliferation of the stem cell derived cellular progeny was detected already at day 5, and characterized by the appearance of multiple sites of engraftment, with structures of single or pseudostratified columnar epithelium surrounding small cavities. The striking histological resemblance to developing embryonic ectoderm, and the formation of epiblast-like structures was supported by the expression of the markers OCT4, NANOG, SSEA-4 and KLF4, but a lack of REX1. The early neural marker NESTIN was uniformly expressed, while markers linked to gastrulation, such as BMP-4, NODAL or BRACHYURY were not detected. Thus, observations on day 5 indicated differentiation comparable to the most early transient cell populations in human post implantation development. Confirming and expanding on previous findings from HS181 xenografts, these early events were followed by an increasingly chaotic development, incorporated in the formation of a benign teratoma with complex embryonic components. In the mature HS181 teratomas not all types of organs/tissues were detected, indicating a restricted differentiation, and a lack of adequate spatial developmental cues during the further teratoma formation. Uniquely, a kinetic alignment of rare complex structures was made to human embryos at diagnosed gestation stages, showing minor kinetic deviations between HS181 teratoma and the human counterpart.

    Pre- and post-operative stomach volumes can be important determinants for effectiveness of laparoscopic sleeve gastrectomy (LSG) in causing weight loss. There is little existing data on the volumes of stomach preoperatively and that excised during LSG. This study was designed to evaluate the change in gastric volume after LSG using multi-detector CT and to correlate it with early post-operative weight loss. Twenty consecutive patients with BMI ≥ 40 kg/m(2) and medical comorbidities underwent LSG between October 2011 and October 2013 and were analysed prospectively. The pre-operative stomach volume was measured by MDCT done 1-3 days before the surgery. LSG was performed in the standard manner using a 36F bougie. The volume of excised stomach was measured by distending the specimen with saline. MDCT of the upper abdomen was repeated 3 months postoperatively to calculate the gastric sleeve volume. Weight loss and resolution of comorbidities were documented. The mean pre-operative weight of patients was 123.90 kg, and the mean pre-operative stomach volume on MDCT was 1,067 ml. The stomach volume on pre-operative MDCT correlated with pre-operative weight and BMI. The mean volume of the excised stomach was 859 ml when measured by distension of the specimen and 850 ml on MDCT. After 3 months post surgery, the mean volume of gastric sleeve on MDCT was 217 ml, and the mean weight of the patients was 101.22 kg. The volume of the excised stomach calculated by MDCT correlated with the weight loss achieved 3 months postoperatively. However, no correlation was seen between the gastric sleeve volume 3 months postoperatively and weight loss during this period. MDCT is a good method to measure gastric volume before and after LSG. Early post-operative weight loss (3 months) correlates well with the volume of the excised stomach but not with that of the gastric sleeve.

    Fundoplication during esophagogastrostomy (EG) after proximal gastrectomy (PG) is a useful procedure to prevent reflux esophagitis, but it is unclear how much of the remnant stomach should be wrapped around the esophagus. We analyzed data from 101 patients who underwent PG for upper third early gastric cancer between 1999 and 2011. In all, 64 patients underwent EG, 25 underwent jejunal interposition (JI), and 12 underwent jejunal pouch interposition (JPI). We compared intraoperative details and postoperative outcomes, and investigated the relationships between the degree of the fundoplication during EG and endoscopic findings. The length of the operation was significantly shorter in the EG group than in the other 2 groups (P 180° wrap of the remnant stomach around the esophagus than in patients with a smaller wrap (P = .0008). The rate of body weight loss was significantly less in the EG group compared with the other 2 groups (P 180° wrap as the optimal reconstructive procedure. Copyright © 2014 Mosby, Inc.

  13. Does facial resemblance enhance cooperation?

    Directory of Open Access Journals (Sweden)

    Trang Giang

    Full Text Available Facial self-resemblance has been proposed to serve as a kinship cue that facilitates cooperation between kin. In the present study, facial resemblance was manipulated by morphing stimulus faces with the participants' own faces or control faces (resulting in self-resemblant or other-resemblant composite faces. A norming study showed that the perceived degree of kinship was higher for the participants and the self-resemblant composite faces than for actual first-degree relatives. Effects of facial self-resemblance on trust and cooperation were tested in a paradigm that has proven to be sensitive to facial trustworthiness, facial likability, and facial expression. First, participants played a cooperation game in which the composite faces were shown. Then, likability ratings were assessed. In a source memory test, participants were required to identify old and new faces, and were asked to remember whether the faces belonged to cooperators or cheaters in the cooperation game. Old-new recognition was enhanced for self-resemblant faces in comparison to other-resemblant faces. However, facial self-resemblance had no effects on the degree of cooperation in the cooperation game, on the emotional evaluation of the faces as reflected in the likability judgments, and on the expectation that a face belonged to a cooperator rather than to a cheater. Therefore, the present results are clearly inconsistent with the assumption of an evolved kin recognition module built into the human face recognition system.

    Gastric surgery may be performed for the treatment of a variety of benign and malignant diseases of the upper gastrointestinal tract, including peptic ulcers and gastric carcinoma. Radiographic studies with water-soluble contrast agents often are obtained to rule out leaks, obstruction, or other acute complications during the early postoperative period. Barium studies may also be obtained to evaluate for anastomotic strictures or ulcers, bile reflux gastritis, recurrent tumor, or other chronic complications during the late postoperative period. Cross-sectional imaging studies such as CT are also helpful for detecting abscesses or other postoperative collections, recurrent or metastatic tumor, or less common complications such as afferent loop syndrome or gastrojejunal intussusception. It is important for radiologists to be familiar not only with the radiographic findings associated with these various abnormalities but also with the normal appearances of the postoperative stomach on radiographic examinations, so that such appearances are not mistaken for pseudoleaks or other postoperative complications. The purpose of this article is to describe the normal postsurgical anatomy after the most commonly performed operations (including partial gastrectomy, esophagogastrectomy and gastric pull-through, and total gastrectomy and esophagojejunostomy) and to review the acute and chronic complications, normal postoperative findings, and major abnormalities detected on radiographic examinations in these patients.

    Full Text Available Adenosqamous carcinoma of the stomach is a rare subtype, accounting for less than 0.4 % of cases of gastric cancer. It is aggressive and tends to be present in advanced stages with a worse prognosis than typical gastric adenocarcinoma. This case is interesting because of its rarity and histogenesis. Based on the fact that clinically and endoscopically, it resembles intestinal-type adenocarcinoma, histopathology is required to make definitive diagnosis. Presented here is a case report of a 70-year-old male that presented with the features of gastric outlet obstruction. Distal gastrectomy with D1duodenectomy showed adenosquamous carcinoma at the distal end of the stomach with metastatic deposits in 4/6 perigastric lymphnodes. With immunohistochemistry, the squamous component demonstrated CK5/6 positivity and the adenocarinoma component was positive for CK7. [Arch Clin Exp Surg 2017; 6(4.000: 217-220

    We report about two patients with gastric neuroendocrine tumours (carcinoids) and chronic atrophic gastritis. A 68-year-old woman presented with nonspecific dyspeptic complaints. Gastroscopy revealed a single neuroendocrine tumour of the corpus. 33 months after endoscopic therapy she is free of detectable tumour. As cause of an upper gastrointestinal bleeding in a 75-year-old woman, a small ulcerated fundic neuroendocrine tumour was found together with other multiple tumours. Repeated endoscopic removals of these and further developing similar tumours were necessary during a follow-up of 25 months. Neuroendocrine tumours of the stomach are rare and are potentially malignant. According to their clinical context they can be divided into three subtypes: 1. tumours in chronic atrophic gastritis, 2. tumours in multiple endocrine neoplasia type I, 3. sporadic tumours, not associated with particular diseases. The first two types may be gastrin-promoted; they occur often multifocal only in the nonantral mucosa and seem to behave relatively benign. Metastasis limited to regional lymph nodes has not been described often. The very rare third type appears solitary in the whole stomach and seems to have a higher malignant potential with frequent distant metastasis to the liver. Therapy should be mainly guided by subtype and tumour size.

  9. Intestinal metaplasia of the stomach. A status report.

    Science.gov (United States)

    Stemmermann, G N

    1994-07-15

    Intestinal metaplasia in the stomach increases the risk of gastric cancer, and the increased risk is proportional to the extent of the metaplasia. This risk could be generated by one or more mechanisms: (1) the metaplastic tissue is an early step in a multistep induction process; (2) the metaplastic tissue is an epigenetic change that raises the pH of gastric juice by replacing oxyntic mucosa, favoring the growth of a bacteria capable of generating endogenous mutagens; and/or (3) the metaplasia is only a marker for chronic gastritis due to H. pylori infection or pernicious anemia. With the last mechanism, the inflammatory response favors intramural mutagenesis that might result in metaplasia or neoplasia as independent events. Finding gene rearrangements common to both metaplastic and neoplastic tissue may establish a direct link between them, but too few have been identified to account for the large number of stomach cancers that develop in high risk populations. Histochemical and immunochemical stains that identify enzymes or mucosubstances may suggest that metaplastic epithelial cells resemble small or large intestinal cells, but they are distinctly different from both. Moreover, these stains do not indicate whether a given cytologic change is genetic or epigenetic; therefore, they cannot be used to define the relationship between metaplasia and neoplasia. It is unnecessary for practicing physicians to await resolution of this question. It can be assumed that any person with extensive metaplasia is at high risk for gastric cancer and should be subject to periodic screening. The extent of the metaplastic process is probably more important than the metaplastic subtype.

    Symptoms of epigastric pain raise the possibility of peptic ulcer disease and lead to an examination of the stomach and duodenum. Hematemesis or melena is also a strong indication. The nausea-vomiting complex on a subacute or chronic basis raises the possibility of an obstructive lesion. A palpable mass in the upper abdomen may involve the stomach. Weight loss and anorexia are less specific symptoms but can occur with gastric cancer. Major changes in indications have occurred now that ultrasonography, computed tomography (CT), and magnetic resonance (MR) imaging are available. No longer is the gut studied to detect extra-gut disease. Currently, the duodenal contour is not important in the search for pancreatic disease. All intra-abdominal structures can now be seen directly using CT or ultrasound

    The stomach is a digestive organ that has important roles in human physiology and pathophysiology. The developmental origin of the stomach is the embryonic foregut, which also gives rise a number of other structures. There are several signaling pathways and transcription factors that are known to regulate stomach development at different stages, including foregut patterning, stomach specification, and gastric regionalization. These developmental events have important implications in later homeostasis and disease in the adult stomach. Here we will review the literature that has shaped our current understanding of the molecular mechanisms that coordinate gastric organogenesis. Further we will discuss how developmental paradigms have guided recent efforts to differentiate stomach tissue from pluripotent stem cells. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2015-01-15

    In vertebrates, the digestive tract develops from a uniform structure where reciprocal epithelial-mesenchymal interactions pattern this complex organ into regions with specific morphologies and functions. Concomitant with these early patterning events, the primitive GI tract is colonized by the vagal enteric neural crest cells (vENCCs), a population of cells that will give rise to the enteric nervous system (ENS), the intrinsic innervation of the GI tract. The influence of vENCCs on early patterning and differentiation of the GI tract has never been evaluated. In this study, we report that a crucial number of vENCCs is required for proper chick stomach development, patterning and differentiation. We show that reducing the number of vENCCs by performing vENCC ablations induces sustained activation of the BMP and Notch pathways in the stomach mesenchyme and impairs smooth muscle development. A reduction in vENCCs also leads to the transdifferentiation of the stomach into a stomach-intestinal mixed phenotype. In addition, sustained Notch signaling activity in the stomach mesenchyme phenocopies the defects observed in vENCC-ablated stomachs, indicating that inhibition of the Notch signaling pathway is essential for stomach patterning and differentiation. Finally, we report that a crucial number of vENCCs is also required for maintenance of stomach identity and differentiation through inhibition of the Notch signaling pathway. Altogether, our data reveal that, through the regulation of mesenchyme identity, vENCCs act as a new mediator in the mesenchymal-epithelial interactions that control stomach development. © 2015.

    In this study, we established a radioimmunoassay (RIA) specific for ghrelin from the bullfrog Rana catesbeiana using a novel antibody raised against the C-terminal amino acid sequence of bullfrog ghrelin [13-28]. We also examined the distribution of ghrelin-producing cells in the stomachs of bullfrogs using this antibody and a cRNA probe specific for the bullfrog ghrelin gene. Ghrelin levels in plasma and stomach extracts were approximately 150 fmol/ml and 83-135 fmol/mg wet tissue, respectively. Reverse-phase high performance liquid chromatographic analysis, combined with bullfrog ghrelin RIA, revealed that ghrelin immunoreactivity in the stomach was composed of non-acylated ghrelin (des-acyl ghrelin) and several acylated forms of ghrelin bearing different fatty acid modifications, which could induce increases in intracellular Ca2+ in cells expressing the rat GH secretagogue receptor. In the stomach, the major storage form was acylated ghrelin. In bullfrog plasma, however, the majority of ghrelin immunoreactivity was des-acyl ghrelin and C-terminal fragments of frog ghrelin. Acylated ghrelin forms comprised only minor peaks. Ghrelin-immunopositive and ghrelin mRNA-expressing cells were observed within the mucosal layer of the stomach. Following starvation, significant increases in plasma ghrelin levels and stomach ghrelin mRNA levels were observed as early as 10 days after starvation. These results indicate that ghrelin is present in the stomach and plasma of the bullfrog, which can be detected with our novel antibody. Interestingly, the primary storage form of ghrelin in the stomach differed from the circulating form dominating in the plasma. Furthermore, increases in ghrelin levels in plasma and mRNA levels in the stomach after starvation suggest the possible involvement of ghrelin in energy homeostasis in the bullfrog.

  17. Xanthomas of the stomach: a report of two cases

    Directory of Open Access Journals (Sweden)

    2012-05-01

    Full Text Available Gastrointestinal tract xanthomas are non tumor, well demarcated mucosal lesions that consist of foamy histiocytes, most commonly diagnosed in the stomach. The histologic appearance of xanthomas can resemble certain malignant lesions. After retrospective data base search, we have encountered only 2 cases of xanthomas, both in the antral part of the stomach. Lamina propria of the mucosa contained rare, chronic inflammatory infiltrate and clusters of oval and polygonal cells with abundant, foamy cytoplasm. The cytoplasm of described cells did not show the presence of mucin (Periodic acid-Schiff (PAS and Alcian blue staining. The cells showed distinct cytoplasmic CD68 positivity and CKMNF116 negativity, which confirmed the diagnosis of xanthoma. Given the frequent association of xanthomas and known precancerous lesions of gastric mucosa, and occasional coexistence of malignant change, we need to pay attention to its diagnosis, and it is advisable to use both histochemical and immunohistochemical methods.

  18. Social perception of facial resemblance in humans.

    2008-02-01

    Two lines of reasoning predict that highly social species will have mechanisms to influence behavior toward individuals depending on their degree of relatedness. First, inclusive fitness theory leads to the prediction that organisms will preferentially help closely related kin over more distantly related individuals. Second, evaluation of the relative costs and potential benefits of inbreeding suggests that the degree of kinship should also be considered when choosing a mate. In order to behaviorally discriminate between individuals with different levels of relatedness, organisms must be able to discriminate cues of kinship. Facial resemblance is one such potential cue in humans. Computer-graphic manipulation of face images has made it possible to experimentally test hypotheses about human kin recognition by facial phenotype matching. We review recent experimental evidence that humans respond to facial resemblance in ways consistent with inclusive fitness theory and considerations of the costs of inbreeding, namely by increasing prosocial behavior and positive attributions toward self-resembling images and selectively tempering attributions of attractiveness to other-sex faces in the context of a sexual relationship.

  19. The stomach-brain axis.

    Science.gov (United States)

    Holtmann, Gerald; Talley, Nicholas J

    2014-12-01

    The stomach has distinct functions in relation to the ingestion and handling of solids and liquids. These functions include storage of the food before it is gradually emptied into the duodenum, mechanical crushing of larger food particles to increase the surface area, secretion of an acidic enzyme rich gastric juice and mixing the ingested food with the gastric juice. In addition, the stomach 'senses' the composition of the gastric content and this information is passed via the vagal nerve to the lateral hypothalamus and the limbic system, most likely as palatability signals that influence eating behaviour. Other sensory qualities related to the stimulation of gastric tension receptors are satiety and fullness. Receptors that respond to macronutrient content or gastric wall tension influence appetite and meal related hormone responses. The ingestion of food - in contrast to an infusion of nutrients into the stomach - has distinct effects on the activation of specific brain regions. Brain areas such as thalamus, amygdala, putamen and praecuneus are activated by the ingestion of food. Gastric nutrient infusion evokes greater activation in the hippocampus and anterior cingulate. The brain integrates these interrelated neural and hormonal signals arising from the stomach as well as visual, olfactory and anticipatory stimuli that ultimately influence eating and other behavioural patterns. Furthermore, there is now good evidence from experimental studies that gastric afferents influence mood, and animal studies point towards the possibility that gastric dysfunction may be a risk factor for mood disorders such as anxiety and depression. The stomach is also not only colonised by Helicobacter pylori but a large array of bacteria. While there is sufficient evidence to suggest that H. pylori may alter caloric intake and mood, the role of other gastric microbiome for the brain function is unknown. To address this appropriate targeted gastric microbiome studies would be

    This study examines the association between intake of selected macronutrients and the risk of stomach cancer in a Northern American population. Mailed questionnaires were completed between 1994 and 1997 in eight Canadian provinces by 1,181 incident, histologically confirmed cases of stomach cancer and 5,039 population controls. Information on nutrient intake was obtained using a food frequency questionnaire. Odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) were derived through unconditional logistic regression to adjust for potential confounders, including an estimate of total energy intake. Intakes of total fat, saturated fat, and cholesterol were significantly associated with the risk of stomach cancer: The ORs for the highest versus the lowest quartile were 1.58 (95% CI 1.13-2.20), 1.86 (95% CI 1.37-2.52), and 1.75 (95% CI 1.36-2.25), respectively. Total fiber was inversely associated with stomach cancer (p = 0.03). The positive associations with intake of total fat and saturated fat were apparently stronger in women, overweight or obese subjects, and ever smokers. Saturated fat was specifically associated with increased risk of gastric cardia cancer, with an OR of 3.31 (95% CI 1.48-7.43). A diet high in saturated fat appears to increase the risk of stomach cancer, particularly among obese subjects and for gastric cardia cancer.

    CT is a valuable method for preoperative staging of patients with stomach cancers. However, in patients with poor distension of the stomach and scanty fat between the stomach and adjacent organs, CT findings may indicate a false impression of gastric wall thickening and cannot provide the precise extent of stomach cancer. We studied the usefulness of gastric distension by gas-forming agent in 28 cases of pathologically confirmed gastric cancers on CT. Comparative analysis between CT findings and surgical pathologic findings was done in 22 cases who underwent surgery. The results were as follows; 1. Conventional CT failed to define the wall thickening or masses of the stomach, in 14 cases of 23 advanced gastric cancers, while CT with gas distension technique allowed good visualization in all advanced gastric cancers. 2. In 2 cases of 5 early gastric cancers, CT with gas distension technique could detect focal thickening of the gastric wall, even less than 1cm thickness. 3. Among 13 cases with indistinguishable border between stomach and liver on conventional CT, 7 cases were diagnosed as negative invasion on CT with gas distension technique and 5 cases of these were confirmed by surgery. 4. Among 11 cases with indistinguishable border between stomach and pancreas on conventional CT, 3 cases were diagnosed as negative invasion on CT with gas distension technique, all of which were confirmed by surgery. 5. There was no significant difference between conventional CT and CT with gas distension technique of the stomach to diagnose invasion into transverse colon, transverse colon, transverse mesocolon, lymph node metastasis, and various distant metastasis.

    Breast cancer with stomach metastasis rare with an incidence of 1% or less among metastatic breast cancer patients. We experienced a case of breast cancer metastasizing to the stomach in 65-year-old female patient. She experienced dyspepsia and poor oral intake before visiting the clinic. Diffuse infiltration with nodular mucosal thickening of the stomach wall was observed, suggesting advanced gastric cancer based on gross endoscopic finding. Spread of poorly cohesive tumor cells in the gastric mucosa observed upon hematoxylin and eosin stain resembled signet ring cell carcinoma, but diffuse positive staining for GATA3 in immunohistochemical stain allowed for a conclusive diagnosis of breast cancer metastasizing to the stomach. Based on the final diagnosis, systemic chemotherapy was administered instead of primary surgical resection. After 2 cycles of docetaxel administration, she showed a partial response based on abdominal computed tomography scan. This case is an unusual presentation of breast cancer metastasizing to the gastrointestinal tract.

    Full Text Available Steinstrasse or “stone street” is an expected complication after extracorporeal shock wave lithotripsy in patients with high stone burden. However, there are published reports of multiple ureterolithiasis resembling steinstrasse in patients with distal renal tubular acidosis. Here we report an uncommon case of a 60-year-old woman who presented with right renal calculi. Her right ureter was studded with multiple calculi up to the vesicoureteric junction. The affected right kidney was nonfunctional and was managed by nephroureterectomy.

    A study was made of the X-ray picture of the stomach postulcer scar in correlation with fibrogastroscopy in 39 patients. The X-ray picture was characterized by considerable polymorphism and at the same time it was difficult to single out pathognomonic features. For specified diagnosis and differentiation the detection of the postulcer scar must become a multifaceted roentgenoendoscopic problem. Stomach ulcers may scar, sometimes with the complete regeneration of the mucosa relief, however their recurrences can develop in the zone of the postulcer scar

    There were four types of stomach contour included eutonic, hypotonic, steerhorn, and cascade. The aim of this study is to clarify relationship between incidence of stomach cancer and contour variation of the stomach. Double- contrast upper gastrointestinal study was performed in 1,546 patients, who had dyspepsia or other gastrointestinal tract symptoms. The radiographs were classified into the four types including eutonic, hypotonic, steerhorn, and cascade according to stomach contour in relation to body build. We also reviewed pathologic reports on endoscopic biopsy or surgical specimen. We studied the presence of relationship between incidence of stomach cancer and variation of stomach contour. We also examined the incidence of gastritis and gastric ulcer to the stomach contour variation. Of total 1,546 patients, eutonic stomach were 438(28.3%), hypotonic 911(58.9%), steerhorn 102(6.5%) and cascade 95(6.2%). Stomach cancer was found in 139(31.7%) of 438 eutonic stomachs, in 135(14.8%) of 911 hypotonic, in 42(41.2%) of 102 steerhorn, and in 24(36.9%) of 95 cascade (P=0.001). In hypotonic stomach, the incidence of stomach cancer was lower compared to the other three types significantly (p<0.05). Gastritis or gastric ulcer was found in 146(33.3%) of eutonic stomach, in 293(32.1%) of hypotonic, in 36(35.2%) of steerhorn, and in 26(27.3%) of cascade (p=0.640). In conclusion, gastric contour variation seems to be a factor affecting development of stomach cancer. The patients with hypotonic stomach may have lower incidence of stomach cancer than that of the other types. There was no relationship between the contour and gastric ulcer

    Radiolabelled antacid preparations have been monitored in the stomach using gamma scintigraphy. The stomach contents were labelled with technetium-99m and two antacid preparations with indium-113m. It has been shown that the antacid containing aluminium hydroxide and magnesium oxide mixed and emptied with the other stomach contents. An alginate containing preparation tended to float on the food and emptied only slowly from the stomach. (Auth.)

    The gastrointestinal tract of the snake has various distinctions from mammals, birds and other reptiles. Five gopher snakes (Pituophis catenifer) were studied in relation to the gross anatomical measurements of visceral organs relative to body length as well as the histology of the oesophagus and the stomach. The oesophagus closely resembles the empty stomach upon gross examination. A small palpable thickening was observed at the junction of the oesophagus with the stomach. In both the oesophagus and the stomach, there were cellular and structural differences observed in the tunica mucosa which can be linked to the feeding habits and natural biology of the snake when compared to those of mammals. Both oesophagus and stomach were lined by simple columnar to pseudostratified columnar epithelium. There were no glands in the wall of the oesophagus. Scattered ciliated triangular cells (brush cells) were present among the columnar epithelial cells in the distal portion of the oesophagus. The stomach can be divided into three portions (proximal, middle and distal). The stomach has a small non-glandular portion with low folds. After this small non-glandular portion, glands started to appear and gradually increase in quantity. The largest quantity of glands appeared in the middle portion of the stomach with more branching folds resulting in a decrease in the lumen diameter. The tunica muscularis increased in thickness at the oesophageal and the pyloric-duodenal junctions. Positive statistical correlations were established in thickness of the tunica muscularis between proximal and distal portions of the oesophagus and the stomach. © 2011 Blackwell Verlag GmbH.

  15. Neurogenic tumors of the stomach

    1983-08-01

    The general and radiologic features of neurogenic tumors of the stomach are reviewed in connection with 18 cases (16 benign and 2 maglignant tumors). Such neurogenic tumors are rare in the stomach, representing less than 0.5% of all tumors. Solitary neurogenic tumors must be differentiated from those encountered during von Recklinghausen's disease. Radiological or endoscopic examination can generally determine the benign or malignant nature of solitary neurogenic tumors, which are essentially represented by schwannomas. Since these tumors are submucosal, a deep biopsy is imperative; furthermore, since such tumors are subject to hemorrhage, prior investigation by CT appears advisable to detect possible hypervascularization after injection of contrast material. For patients with von Recklinghausen's disease, a neurofibroma is usually diagnosed when faced with a digestive hemorrhage. Radiological exploration of the entire digestive tract appears essential to confirm the solitary nature of the gastric lesion and to be sure it is responsible for the clinical symptoms.

    The purpose of the present study was to determine the family resemblance of attitude toward body elimination in Kuwaiti participants. This study was conceptualized in the context of the theories of moral development, importance of cleanliness in the Muslim religion, cross-cultural differences in personal hygiene practices, previous research reporting an association between family attitudes and body elimination attitude, and health implications. The 24-item Likert-type format Body Elimination Attitude Scale-Revised was administered to 277 Kuwaiti high school students and 437 of their parents. Females scored higher, indicating greater disgust, than the males. Moreover, sons' body elimination attitude correlated more strongly with fathers' attitude (r = .85) than with that of the mothers (r = .64). Daughters' attitude was similarly associated with the fathers' (r = .89) and the mothers' attitude (r = .86). The high correlations were discussed within the context of Kuwait having a collectivistic culture with authoritarian parenting style. The higher adolescent correlations, and in particular the boys' correlation with fathers than with mothers, was explained in terms of the more dominant role of the Muslim father in the family. Public health and future research implications were suggested. A theoretical formulation was advanced in which "ideal" body elimination attitude is relative rather than absolute, and is a function of one's life circumstances, one's occupation, one's culture and subculture, and the society that one lives in.

    Dik, K.J.; Kalsbeek, H.C.

    1985-01-01

    To obtain radiographic information concerning the equine stomach, a gastrographic contrast examination is required. This study describes this procedure in detail. A powerful radiographic unit, the tubehead linked to an image intensifier and suspended by an electromechanical overhead gantry system, is required. To obtain accurately positioned radiographs during the fluoroscopic examination, a cassette holder with a stationary grid is mounted at the entrance window of the image intensifier. The examination is performed in the unsedated standing horse after 24 hours of starvation, using a combination of survey radiography and fluoroscopic viewing after the inflation of air, followed by the administration of barium sulphate suspension by stomach tube. The gastrographic contrast examination is performed in three experimental animals and 23 abnormal horses. Pneumogastrophy appeared to be valuable to diagnose gastric tumors, to differentiate between gastric tumors and other masses in the cranial abdomen, and to visualize gastric parasites, even in large horses. The use of barium sulphate suspension does not result in an adequate double contrast of the stomach, but it may aid to diagnose esophagogastric or pyloric stenosis and gastric or duodenal ulcers

    Necrotizing fasciitis is a serious infection that originates in the subcutaneous tissues. Although many reports have been published about necrotizing infections of other anatomical sites, retroperitoneal necrotizing soft tissue infection is a rare entity that has been described in only a few case reports. The etiology and clinical course of retroperitoneal necrotizing fasciitis can be variable and it is often difficult to identify the etiology of the infective process. We report a 58-year-old man with rapidly progressive, gas-producing, necrotizing inflammation in the retroperitoneum, complicated with genital involvement resembling Fournier gangrene. The patient was managed successfully by aggressive drainage, debridement, and sequential laparotomies to track and control the extensive necrosis of the retroperitoneum and perineum, in addition to systemic care to control sepsis. After his general condition stabilized, early rectosigmoid adenocarcinoma was identified and resected curatively. He remained well at follow up, six months after discharge. In retrospect, the trigger of the disease process was unclear. Although it was believed possibly to be due to the colon lesion, adenocarcinoma of the rectosigmoid colon was identified and the patient was managed successfully. Similar to necrotizing infections at other anatomical sites, early diagnosis and timely surgical intervention and systemic antimicrobial therapy are mandatory for treating patients with retroperitoneal necrotizing fasciitis.

    2016-12-01

    The Hedgehog (Hh) signaling pathway not only plays a key part in controlling embryonic development, but in the adult stomach governs important cellular events such as epithelial cell differentiation, proliferation, gastric disease, and regeneration. In particular, Sonic Hedgehog (Shh) signaling has been well studied for its role in gastric physiology and pathophysiology. Shh is secreted from the gastric parietal cells and contributes to the regeneration of the epithelium in response to injury, or the development of gastritis during Helicobacter pylori infection. Dysregulation of the Shh signaling pathway leads to the disruption of gastric differentiation, loss of gastric acid secretion and the development of cancer. In this chapter, we will review the most recent findings that reveal the role of Shh as a regulator of gastric physiology, regeneration, and disease. Copyright © 2016 Elsevier Ltd.

    The stomach, an organ derived from foregut endoderm, secretes acid and enzymes and plays a key role in digestion. During development, mesenchymal-epithelial interactions drive stomach specification, patterning, differentiation and growth through selected signaling pathways and transcription factors. After birth, the gastric epithelium is maintained by the activity of stem cells. Developmental signals are aberrantly activated and stem cell functions are disrupted in gastric cancer and other disorders. Therefore, a better understanding of stomach development and stem cells can inform approaches to treating these conditions. This Review highlights the molecular mechanisms of stomach development and discusses recent findings regarding stomach stem cells and organoid cultures, and their roles in investigating disease mechanisms. © 2016.

    Pulmonary arterial hypertension (PAH) is a commonly fatal pulmonary vascular disease that is often diagnosed late and is characterised by a progressive rise in pulmonary vascular resistance resulting from typical vascular remodelling. Recent data suggest that vascular damage plays an important role in the development of radiation-induced pulmonary toxicity. Therefore, the authors investigated whether irradiation of the lung also induces pulmonary hypertension. Different sub-volumes of the rat lung were irradiated with protons known to induce different levels of pulmonary vascular damage. Early loss of endothelial cells and vascular oedema were observed in the irradiation field and in shielded parts of the lung, even before the onset of clinical symptoms. 8 weeks after irradiation, irradiated volume-dependent vascular remodelling was observed, correlating perfectly with pulmonary artery pressure, right ventricle hypertrophy and pulmonary dysfunction. The findings indicate that partial lung irradiation induces pulmonary vascular remodelling resulting from acute pulmonary endothelial cell loss and consequential pulmonary hypertension. Moreover, the close resemblance of the observed vascular remodelling with vascular lesions in PAH makes partial lung irradiation a promising new model for studying PAH.

  4. Neurogenesis in Aplysia californica resembles nervous system formation in vertebrates

    Jacob, M.H.

    1984-01-01

    The pattern of neurogenesis of the central nervous system of Aplysia californica was investigated by [ 3 H]thymidine autoradiography. Large numbers of animals at a series of early developmental stages were labeled with [ 3 H]thymidine for 24 or 48 hr and were subsequently sampled at specific intervals throughout the life cycle. I found that proliferative zones, consisting of columnar and placodal ectodermal cells, are established in regions of the body wall adjacent to underlying mesodermal cells. Mitosis in the proliferative zones generates a population of cells which leave the surface and migrate inward to join the nearby forming ganglia. Tracing specific [ 3 H]thymidine-labeled cells from the body wall to a particular ganglion and within the ganglion over time suggests that the final genomic replication of the neuronal precursors occurs before the cells join the ganglion while glial cell precursors and differentiating glial cells continue to divide within the ganglion for some time. Ultrastructural examination of the morphological features of the few mitosing cells observed within the Aplysia central nervous system supports this interpretation. The pattern of neurogenesis in the Aplysia central nervous system resembles the proliferation of cells in the neural tube and the migration of neural crest and ectodermal placode cells in the vertebrate nervous system but differs from the pattern described for other invertebrates

    Full Text Available Evolutionary theory predicts that men should be more concerned with issues of false paternity than women should be concerned with false maternity. In an earlier study (Volk and Quinsey, 2002, we studied how infant cues of resemblance influenced adults' hypothetical adoption decisions. We found that self-perceived cues of resemblance were significantly more important in men's decisions than in women's. Since that study was published, conflicting results have been reported regarding a sex-difference in the importance of cues of resemblance for adoption preference. We therefore sought to replicate our findings in three new studies. In all three studies, we replicated the initial finding of a larger correlation between ratings of resemblance and ratings of adoption preference among men than among women. We also found a trend towards slightly higher global resemblance scores in younger children, suggesting that adults view infants as more anonymous and/or less uniquely distinctive than older children. However, there was wide variance in both the global resemblance and developmental changes in resemblance amongst the different child stimuli used.

    The stomach is traditionally regarded as a hollow muscular sac that initiates the second phase of digestion. Yet this simple view ignores the fact that it is the most sophisticated endocrine organ with unique physiology, biochemistry, immunology and microbiology. All ingested materials, including our nutrition, have to negotiate this organ first, and as such, the stomach is arguably the most important segment within the GI tract. The unique biological function of gastric acid secretion not only initiates the digestive process but also acts as a first line of defence against food-borne microbes. Normal gastric physiology and morphology may be disrupted by Helicobacter pylori infection, the most common chronic bacterial infection in the world and the aetiological agent for most peptic ulcers and gastric cancer. In this state-of-the-art review, the most relevant new aspects of the stomach in health and disease are addressed. Topics include gastric physiology and the role of gastric dysmotility in dyspepsia and gastroparesis; the stomach in appetite control and obesity; there is an update on the immunology of the stomach and the emerging field of the gastric microbiome. H. pylori-induced gastritis and its associated diseases including peptic ulcers and gastric cancer are addressed together with advances in diagnosis. The conclusions provide a future approach to gastric diseases underpinned by the concept that a healthy stomach is the gateway to a healthy and balanced host. This philosophy should reinforce any public health efforts designed to eradicate major gastric diseases, including stomach cancer. PMID:26342014

    Microbiota in human alimentary tract plays important roles for homeostatic maintenance of the body. Compositional difference of gut microbiota is tightly associated with susceptibility of many diseases, including inflammatory diseases, obesity, diabetes mellitus, cancer, and atherosclerosis. "Dysbiosis" refers to a state of imbalance among the colonies of microorganisms within the body, which brings abnormal increase of specific minor components and decrease in the normally dominant species. Since stomach secrets strong acid for its digestive role, this organ has long been thought a sterile organ. However, the discovery of Helicobacter pylori (H. pylori) has changed the concept. This bacterium has proven to cause gastritis, peptic ulcer, and gastric cancer. However, recent cross-sectional studies revealed that H. pylori carriers had a decreased risk of developing immunological diseases, such as asthma. H. pylori coinfection also suppresses inflammatory bowel diseases. This review describes human gastric microbiota by discussing its mutual interaction and pathogenic enrollment. Gastric "dysbiosis" may affect host inflammatory response and play important role for gastric pathogenesis. We will topically discuss enrollment of dysbiosis for genesis of gastric cancer as well as for disruption of immunological homeostasis affecting oncogenic resistance.

    Pentacaine is a local anaesthetic which exhibited positive effects on healing of model ulcers in the rat stomach. The in situ disappearance of pentacaine from the ulcerous and intact rat stomach was studied. Gastric ulcers were produced by oral administration of phenylbutazone (200 mg/kg) 3.5 h before absorption experiment. Pentacaine exhibited a biexponential decrease from the lumen of the stomach, the rate of which was essentially the same in both groups. The total amount of pentacaine absorbed was small because of extremly low absorption rate. (author)

However, it is very important for us to examine anterior wall of the stomach for an early detection of gastric carcinoma. The results of the study are as follows : 1. Frequency of occurrence of the early gastric carcinoma for the anterior wall were 50 cases and 34 cases for the posterior wall out of 84 cases. 2. Only a hospitals have examined the anterior wall of stomach. 3. In case of operation, only a hospitals have used two techniques at for same time single and double contrast studies. 4. Only one hospital used a compression pad and three hospitals had only filing state images taken. 5. In general, l chest of film was used and the number of exposures rouged from 1 to 2 times. Lesions on the anterior wall of the stomach can be shown by the combination of prone single compression and supine double contrast radiographs. Therefore, the conclusion came to the result that the prone single compression and supine double contract technique of the anterior wall are indispensable methods to the routine check of the stomach

    To our knowledge this is the first systemic review that provides an overview of the cutaneous paraneoplastic syndromes (CPS) (i.e., clinical manifestations, pathomechanisms, and treatment modalities) occurring in stomach cancer. CPS are caused by substances produced by stomach cancer and may precede, coincide with, or follow the diagnosis of this malignancy. More than 20 possible CPS in association with stomach cancer have been identified. CPS mostly compromises the patient's quality of life by skin impairment plus discomfort and are often associated with a dismal prognosis on survival. Studies of these CPS not only in stomach cancer have partially contributed to the understanding of pathomechanism and since CPS may be the presenting sign of an occult cancer, cognizance of their features and clinical implications are of considerable importance. Patients with these syndromes should have an appropriate work-up for a possibly occult malignancy with consecutive successful early treatment. Copyright © 2016. Published by Elsevier Ireland Ltd.

    Bacteria are sparsely distributed in the stomach due to the gastric microbicidal barrier. Several innate defenses (low pH, migrating motor complex and the entero-salivary circulation of nitrate) as well as external factors (diet, Helicobacter pylori infection, proton pump inhibitors, antibiotics and stomach diseases) have been shown to influence significantly the microbiota composition in the stomach. In recent years new culture-independent technologies have allowed the investigation of the cross talk that occurs between hosts and stomach-associated microflora, which helps us to understand the role of gastric bacterial flora in the gastrointestinal microbiological system, both in physiological and pathological conditions. Here, we reviewed the literatures related to this topic and set the stage for future developments of the field. © 2013 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

    This study was performed to evaluate histopathologic features of advanced gastric cancer (AGC) to predict FDG uptake on PET. 153 patients(102 men; mean age, 55 y) were diagnosed with AGC by surgery were included in this study. PET images were evaluated by visual and semi-quantitative analysis of FDG uptake in primary tumors. Primary tumors size were measured and divided according to Borrmann classification. Tumor histology was classified under WHO classification, depth of invasion and Iymphovascular invasion. The tumors were also grouped by high cellular(cellularity = 50%) and low cellular group (<50%). Microscopic growth type was based on Lauren classification. Stromal fibrosis degree and inflammatory cell infiltration amount was graded as low(none∼mild), or high(moderate∼severe). Lymph node metastases was assessed in all patients. Statistical analyses were performed to evaluate differences in SUV as to histopathologic factors. Of the 153 patients, 21 patients(14%) had primary tumor invisible on initial whole body images. After water ingestion, the tumors became visible in 15 of the 21 patients due to disappearance of physiologic stomach uptake. Polypoid or ulcerofungating tumors, high cellularity, intestinal growth pattern, and larger tumors significantly predicted increased tumor SUVs. Well or moderately differentiated adenocarcinoma tended to show high cellularity and intestinal growth pattern. Poorly differentiated adenocarcinoma had diverse spectrum of histopathology. Signet ring cell carcinomas were mostly ulceroinfiltrative or diffusely infiltrative in macroscopic type and diffuse in microscopic tumor growth. Mucinous adenocarcinomas were mostly low in cellularity. FDG uptake patterns are useful in representing histopathologic characteristics of the entire tumor in gastric cancers. The degree of FDG uptake depends on tumor size, macroscopic type, cellularity, and microscopic growth pattern and it shows no association with well known important prognostic

    2016-01-01

    Leigh disease (LD) is one of the clinical phenotypes of mitochondrial OXPHOS disorders and also known as sub-acute necrotizing encephalomyelopathy. The disease has an incidence of 1 in 77,000 live births. Symptoms typically begin early in life and prognosis for LD patients is poor. Currently, no clinically effective treatments are available. Suitable animal and cellular models are necessary for the understanding of the neuropathology and the development of successful new therapeutic strategies. In this study we used the Ndufs4 knockout (Ndufs4(-/-)) mouse, a model of mitochondrial complex I deficiency. Ndusf4(-/-) mice exhibit progressive neurodegeneration, which closely resemble the human LD phenotype. When dissecting behavioral abnormalities in animal models it is of great importance to apply translational tools that are clinically relevant. To distinguish gait abnormalities in patients, simple walking tests can be assessed, but in animals this is not easy. This study is the first to demonstrate automated CatWalk gait analysis in the Ndufs4(-/-) mouse model. Marked differences were noted between Ndufs4(-/-) and control mice in dynamic, static, coordination and support parameters. Variation of walking speed was significantly increased in Ndufs4(-/-) mice, suggesting hampered and uncoordinated gait. Furthermore, decreased regularity index, increased base of support and changes in support were noted in the Ndufs4(-/-) mice. Here, we report the ability of the CatWalk system to sensitively assess gait abnormalities in Ndufs4(-/-) mice. This objective gait analysis can be of great value for intervention and drug efficacy studies in animal models for mitochondrial disease. Copyright © 2015 Elsevier B.V. All rights reserved.

    Systematic double contrast study of stomach allows differences as small as 1/10 mm to be recognized and thereby also the visualization of all relevant pathologic-anatomic differences in the gastric mucosa. This representation of fine details has made possible the detection and accurate diagnosis of small polyps, superficial acute and chronic linear ulcers, ulcer scars, and 21 early gastric carcinomas. Radiology and endoscopy, in spite of their differences, have proven to be of equal value. Superficial indentations, changes in gastric contour, and localized rididity of a gastric segment are more easily shown by x-ray than by endoscopy. (orig.) [de

    The stomach is traditionally regarded as a hollow muscular sac that initiates the second phase of digestion. Yet this simple view ignores the fact that it is the most sophisticated endocrine organ with unique physiology, biochemistry, immunology and microbiology. All ingested materials, including our nutrition, have to negotiate this organ first, and as such, the stomach is arguably the most important segment within the GI tract. The unique biological function of gastric acid secretion not only initiates the digestive process but also acts as a first line of defence against food-borne microbes. Normal gastric physiology and morphology may be disrupted by Helicobacter pylori infection, the most common chronic bacterial infection in the world and the aetiological agent for most peptic ulcers and gastric cancer. In this state-of-the-art review, the most relevant new aspects of the stomach in health and disease are addressed. Topics include gastric physiology and the role of gastric dysmotility in dyspepsia and gastroparesis; the stomach in appetite control and obesity; there is an update on the immunology of the stomach and the emerging field of the gastric microbiome. H. pylori-induced gastritis and its associated diseases including peptic ulcers and gastric cancer are addressed together with advances in diagnosis. The conclusions provide a future approach to gastric diseases underpinned by the concept that a healthy stomach is the gateway to a healthy and balanced host. This philosophy should reinforce any public health efforts designed to eradicate major gastric diseases, including stomach cancer. Published by the BMJ Publishing Group Limited.

  1. Resistance to rupture of the equine stomach

    Directory of Open Access Journals (Sweden)

    Paula A. Di Filippo

    Full Text Available ABSTRACT: Equine colic is an important and common cause of disease and death in horses. Gastric rupture has been extensively described in the literature, and is known to affect expressive numbers of horses. Gastric dilatation, which precedes rupture, may be observed when the animal consumes large amounts of recently harvested grass or drinks water too fast, though diagnosis criteria also include infestation with Gastherophilus and the presence of ileus and distal intestinal obstructions. The objective of the present study was to determine the resistance to rupture of the equine stomach to air (mm Hg and water (L injection. Forty stomachs of young horses (20 geldings and 20 mares with no defined breed were analyzed. Total organ length (cm, weight (g, greater curved length (cm, lesser curved length (cm and height (cm were measured, with no statistical difference between males and females (p > .05. However, stomachs of horses were larger than those of mares and therefore presented higher volumetric capacity (p<0.05. No difference between males and females was observed in the pressure assay (93mmg Hg. Rupture occurred along the greater curvature (99% and on the visceral (80% and diaphragmatic (20% surfaces, across all layers of the gastric wall. Although the equine stomach is relatively small, the organ is considerably resistant to rupture, whether by injection of air or liquid. Horses and mares exhibit similar resistance values, although the stomach of females has smaller volumetric capacity.

  2. Schwannoma of the stomach: a case report.

    2016-01-15

    Schwannomas, also known as neurilemmomas, are benign slow-growing neoplasms originating from a Schwann cell sheath. These neoplasms are rare among the mesenchymal tumors of the gastrointestinal tract. In the stomach, Schwannomas only represent 0.2 % of all gastric tumors; this makes the presentation of a schwannoma in the stomach of a man in his seventh decade unusual. This case report highlights the rarity of a schwannoma at the greater curvature of the stomach because only a few cases have been reported in the literature. This case describes the importance of including gastric schwannomas in the differential diagnosis when preoperative assessment reveals a submucosal gastric mass with gastrointestinal stromal tumor as a leading differential diagnosis because of its common occurrence at this site. A 72-year-old man of Indian origin presented with a painless abdominal mass with nonspecific gastrointestinal upset. An endoscopy showed a submucosal lesion in his stomach measuring 4 × 3 × 2 cm. Histology revealed a benign spindle cell tumor. Immunohistochemistry confirmed the diagnosis of gastric schwannoma. He is on regular follow-up and doing well. It should be remembered that a schwannoma can present as a mass lesion in the stomach and mimic gastrointestinal stromal tumor. Patients should undergo an endoscopy and a biopsy of the lesion should be done. Many patients do not undergo endoscopy which can delay diagnosis and management. As these tumors have an excellent prognosis, surgical removal is sufficient treatment. Surgeons, radiologists, pathologists and gastroenterologists must be aware of this entity.

    2009-08-01

    Full Text Available Abstract Background Metastases to the stomach from an extra-gastric neoplasm are an unusual event, identified in less than 2% of cancer patients at autopsy. The stomach may be involved by hematogenous spread from a distant primary (most commonly breast, melanoma or lung, or by contiguous spread from an adjacent malignancy, such as the pancreas, esophagus and gallbladder. These latter sites may also involve the stomach via lymphatic or haematogenous spread. We present three cases of secondary gastric malignancy. Methods/Results The first is a 19-year-old male who received a diagnosis of testicular choriocarcinoma in September 2004. Metastatic malignancy was demonstrated in the stomach after partial gastrectomy was performed to control gastric hemorrhage. The second is a 75-year-old male, generally well, who was diagnosed with adenocarcinoma of the lung in September 2005. Poorly differentiated adenocarcinoma of the lung was demonstrated in a subsequent biopsy of "gastric polyps". The third is an 85-year-old man with no known history of malignancy who presented for evaluation of iron deficiency anemia by endoscopy in February 2006. Biopsies of the colonic and gastric mucosa demonstrated moderately differentiated invasive colonic adenocarcinoma with metastatic deposits in the stomach. Conclusion While the accurate recognition of these lesions at endoscopy is fraught with difficulty, pathological awareness of such uncommon metastases in the gastric mucosa is essential for accurate diagnosis and optimal patient management.

    Full Text Available The gastrointestinal tract (GIT of vertebrates develops from a simple undifferentiated tube into highly differentiated regions for the digestion and absorption of nutrients. Each region has a different histological structure and gene expression profile that enables the performance of their different functions. The stomach is the most highly derived GIT region and gastric glands are responsible for the secretion of HCl and pepsinogen that enables acid-peptic digestion, representing a functional innovation found exclusively in jawed vertebrates. The mechanisms of GIT organ specification are well studied in some vertebrates including mouse, Xenopus, chicken and some teleost fishes. General embryonic development has been studied in chondrichthyans but not GIT development. In this study we characterize the development of the stomach in the catshark Scyliorhinus canicula, an elasmobranch with a ~5 month development spanning 34 developmental stages. As a representative of basal jawed vertebrate for which genomic information is currently available, the catshark is a suitable model system to characterize the ancient expression and function developmental of physiologically relevant genes. Therefore, during this study we used embryos from a brood stock held in our fish facility to conduct gene expression, protein detection and histological analyses. Our aim was to characterize, at molecular and morphological levels, stomach development and the differentiation of its characteristic secreting glands. The differentiation of the stomach starts around stage 24. However, immunohistochemistry for the gastric proton pump indicates a delayed development of gastric gland that are only visible before hatching at stage 33-34. Supported by NSERC to JMW

    2005-01-01

    Full Text Available Stomach diseases have an important place in the clinical pathology of dogs. Etiological factors can be nutritive, chemical, or infective, but treatment implies certain common general principles and a certain number of therapy protocols which are most often used. On the other hand, a part of the medicines used in the pharmacotherapy of stomach diseases in dogs are taken from the palette of medicines intended for human use, so that a regular dosage and regime of implementation are the main precondition for the success of the applied therapy. Drugs used in the treatment of stomach diseases include antiemetics, prokinetics, antacids, mucoprotectives, anticholinergics, H2-antagonists, proton pump inhibitors, semisynthetic derivatives of prostaglandin E1, and others. The therapy of stomach diseases implies the simultaneous application of several drugs from different pharmacodynamic groups (for instance, an antiemetic, a prokinetic, an antacid, and an Hg antagonist or a proton pump inhibitor when it is necessary to establish a correct regime of implementation because of possible interaction, which will also be discussed in this work.

    Full Text Available Abstract: Politeness principles are universally utilized by the speakers of any language when realizing various speech acts. However, the speakers of particular languages relatively apply politeness due to the cultural norms embedded. The present study attempts to delineate how the Indonesian learners of English (ILE apply the politeness principles in request realizations. Specifically it devotes to the types of politeness strategies applied and resemblance of the indirectness in politeness strategies in requesting acts. The FTAs and indirectness are the theoretical bases used to trace the typologies of both politeness and request strategies. The data werere collected by means of certain elicitation techniques, i.e. DCTs and Role-plays. The analyses werere done through three stages; determining request strategies, politeness strategies, and resemblance of indirectness in politeness. The results show that the indirectness generally is parallel to politeness. Besides, some pragmatic transfers are found in terms of applying native-culture norms in realizing target speech acts.

    We examined whether people can detect analogical resemblance to an earlier experimental episode without being able to recall the experimental source of the analogical resemblance. We used four-word analogies (e.g., robin-nest/beaver-dam), in a variation of the recognition-without-cued-recall method (Cleary, 2004). Participants studied word pairs (e.g., robin-nest) and were shown new word pairs at test, half of which analogically related to studied word pairs (e.g., beaver-dam) and half of which did not. For each test pair, participants first attempted to recall an analogically similar pair from the study list. Then, regardless of whether successful recall occurred, participants were prompted to rate the familiarity of the test pair, which was said to indicate the likelihood that a pair that was analogically similar to the test pair had been studied. Across three experiments, participants demonstrated an ability to detect analogical resemblance without recalling the source analogy. Findings are discussed in terms of their potential relevance to the study of analogical reasoning and insight, as well as to the study of familiarity and recognition memory.

    Stomach cancer is the fourth most common cancer and the second leading cause of cancer- related death through the world. It is predicted that the number of new cancer cases will be more than 15 million cases by 2020. Regarding the lack of studies on this topic in the country, we have thoroughly examined the patho-epidemiology of stomach cancer in Iran. In this cross- sectional study data were collected retrospectively reviewing all new stomach cancer patients in Cancer Registry Center report of health deputy for Iran during a 6-year period (2003-2008). The study also examined the morphology of common stomach cancers. Trends in incidence and morphology underwent joinpoint regression analysis. During the six-year period, a total of 35,171 cases of stomach cancer were registered. Average age standardized rate for females and males were equal to 7.1 and 15.1 per 100,000 persons, respectively. Most common histological type was adenocarcinoma, NOS with 21,980 cases (62.50%). The annual percentage change (APC) in age-standardized incidence rate (per 100,000) was increase in both females and males at 11.1 (CI: 4.3 to 18.3) and 9.2 (CI: 5.2 to 13.4), respectively. According to our results, the incidence of gastric cancer is increasing in Iran, so further epidemiological studies into the etiology and early detection are essential.

Differential radiodiagnosis of tumoral and non-tumoral nature of ulcerations is based on analyzing the combination of X-ray symptoms, because every separate symptom doesn't reflect the whole variety and complexity of X-ray semiotics of the disease

    We compared retrospectively three groups of 150 patients who had undergone radiologic examinations of the stomach and duodenum. Each group was examined with a different barium suspension and radiographic technique: single-contrast (SC), double-contrast (DC), or biphasiccontrast (BC). The radiographs of each study were evaluated for technical quality and visualization of lesions. The number of X-ray exposures, films, and the amount of fluoroscopic time for each study were tabulated. The total radiation dose and cost for each technique were calculated. The BC examinations required the greatest number of radiographic exposures and X-ray films; however, cost was highest for the DC method. Fluoroscopy was significantly longer during the DC procedures, and the total radiation dose was also highest with this technique. Gaseous distention and barium coating of the stomach were equally good for the BC and DC groups, but X-ray penetration of the barium suspension during compression filming was significantly better in the BC and SC groups. Areae gastricae were most frequently seen during the BC studies and artifacts from excess secretions, barium flocculation or gas bubbles were least commonly present using this technique. Significantly more lesions were demonstrated in the stomach with the BC technique than with the other methods; however, the number of lesions found in the duodenum was the same for each technique.

    The present study examined the relationship between stomach cancer and the low intake of fresh fruit and vegetables and/or a high intake of pickled, preserved or salted foods and frequent use of cooking oil. During 139,390 person-year of follow-up of over 13,000 subjects, 116 died from stomach cancer. Using a Cox proportional hazards-regression analysis of relative risk (RR, 95% CI) controlling for age, sex, smoking and other dietary factors, a significant decline was found with a high consumption of green and yellow vegetables (RR=0.4, 95% CI=0.2-0.9). Reductions of between 40 and 50% were also observed with a high consumption of fresh foods (fruit, cuttle fish, tofu, and potatoes), but these associations were not statistically significant. The risk was significantly increased by the high consumption of processed meat (RR=2.7, 95% CI=1.0-7.4) and by the frequent use of cooking oil (RR=4.0, 95% CI=1.3-11.8). The high consumption of pickled food and traditional soups also increased risk, but not significantly. The findings suggest that a diet high in salt and low in vitamins may be associated with an increase in stomach cancer. . Copyright 2002 Cancer Research UK

    The intention of this book is to convey vividly and comprehensively a method, which has been applied in practice and whose basic principle is easy to learn. This technique requires as absolutely necessary equipment only a scanner. Therefore the examination technique is explained in detail with its fundamental principles and specific modifications. The morphologic part of the book wants to point out the systematic procedure to a definite and logic interpretation of the findings, and it arranges the numerous different pathological alterations of the stomach according to the continuous concept of the alway repeating macroscopic basic pattern. For each disease group the typical features, the more rare variants and also the differential diagnosis are presented and special limits for the examination procedure are given. For all important stomach lesions characteristic X-ray images were selected. In some more rare stomach pathologies the short description of the roentgenologic findings is added in order to complete the book, since its intention is not only to be a guide-line, but it shall also be an enceclopaedic adviser.

    A method is described, which extracts stomach region by picture processing technique for double contrast radiographs. The double contrast radiographs, which are used for observing the mucosa folds or morbid state of stomachs, play an important role in X-ray stomach examination. However, the difference in density between the exterior and interior of stomachs is small, and the stomach region overlaps with the complicated background, so that difficulties are present in computer processing. In the present method, the edge intensification with FIR filter and then the thinning of lines are made. Barium-filled regions were extracted by boundary searching, and excluded from the thinned line image. Subsequently, check-up on the connection and branching of the remaining lines and circular and fanshaped searches at line ends are made, so that the stomach boundaries are partly obtained. To extract the stomach region, these are joined together with the boundaries of barium-filled regions already obtained. (J.P.N.)

    Helicobacter pylori ( Hp ) is the primary cause of gastric cancer but we know little of its relative abundance and other microbes in the stomach, especially at the time of gastric cancer diagnosis. Here we characterized the taxonomic and derived functional profiles of gastric microbiota in two different sets of gastric cancer patients, and compared them with microbial profiles in other body sites. Paired non-malignant and tumor tissues were sampled from 160 gastric cancer patients with 80 from China and 80 from Mexico. The 16S rRNA gene V3-V4 region was sequenced using MiSeq platform for taxonomic profiles. PICRUSt was used to predict functional profiles. Human Microbiome Project was used for comparison. We showed that Hp is the most abundant member of gastric microbiota in both Chinese and Mexican samples (51 and 24%, respectively), followed by oral-associated bacteria. Taxonomic (phylum-level) profiles of stomach microbiota resembled oral microbiota, especially when the Helicobacter reads were removed. The functional profiles of stomach microbiota, however, were distinct from those found in other body sites and had higher inter-subject dissimilarity. Gastric microbiota composition did not differ by Hp colonization status or stomach anatomic sites, but did differ between paired non-malignant and tumor tissues in either Chinese or Mexican samples. Our study showed that Hp is the dominant member of the non-malignant gastric tissue microbiota in many gastric cancer patients. Our results provide insights on the gastric microbiota composition and function in gastric cancer patients, which may have important clinical implications.

    In order to achieve more correct diagnosis of gastric lesion, further progress in the technique of diagnosis is much desired. And so, in pursuing the more ideal study, about 7,500 cases of U. G. I. studies taken in Severance Hospital in the past 29 months from May 1969 to September 1971, have been reviewed to evaluate how the following factors will affect the demonstrability of gastric lesion in upper G. I. series. (1) Introduction of air into the stomach by nasogastric tube. (2) Kinds and concentration of barium. (3) Demonstrability according to the position of the patient. (4) Use of antispasmodics. The results may be briefly summarized as follows: 1. The intubation of nasogastric tube gives discomfort temporarily to the patient: however, it has an advantage that the amount of air required for ideal insufflation of the stomach can be controlled under the fluoroscopy. 2. About concentration and type of barium. a) Mikabarium in 90% seems to give the best result in filling study, mucosal relief study and double contrast study. b) Mikabarium in higher concentration adheres to the mucosa better, thus resulting in good double contrast: however, it tends to coagulate each other in the high concentration. c) Micropaque powder of 110% solution produces good double contrast, but it has the disadvantage of making air bubbles. d) When water is given prior to barium ingestion, the anterior wall of stomach is better demonstrated with mucosal relief study. e) To get better result in contrast study, the selection of barium is important as well as rapid and proper positioning of the patient and abdominal respiratory movement. 3. Demonstrability of the stomach lesion according to the position. a) The small lesion either in pylorus or in antrum can be best demonstrated by compression technique of double contrast method in supine position. b) The mucosal relief study in prone by adequate air insufflation was proper to demonstrate the lesion of anterior wall. c) In the lesion of the

    An 82-year-old woman presented to our hospital with a complaint of frequent vomiting. She was admitted for intensive examination and treatment. Abdominal computed tomography revealed that her stomach was severely expanded, and the wall of the ascending colon was thickened throughout its circumference. Upper gastrointestinal endoscopy uncovered severe stenosis in the pylorus and an elevated lesion resembling a submucosal tumor on the posterior wall of the pylorus. Biopsies of the lesion revealed that it was of Group 1. On colonoscopy, type 2 cancer was found in the ascending colon throughout the circumference, and the biopsies revealed that it was of Group 5. Upper gastrointestinal endoscopy was repeated, and the same result was obtained. The possibility of malignancy could not be excluded; therefore, distal gastrectomy and right colectomy were performed. In terms of histopathology, both resected specimens displayed poorly differentiated adenocarcinoma; however, immunohistochemical studies revealed differences in staining at the two sites. The case was diagnosed as synchronous double cancer involving gastric cancer resembling a submucosal tumor with stenosis in the pylorus and ascending colon cancer. Gastric cancer resembling a submucosal tumor is usually difficult to diagnose on biopsy. If the endoscopic findings reveal an elevated lesion resembling a submucosal tumor with stenosis, then the possibility of carcinoma should be considered, and the most suitable treatment should be selected.

Grady (1999 draws attention to this problem and calls for a more serious study of the latter type of metaphor. The present paper takes up this challenge on the basis of a small corpus of ‘animal’ metaphors in English, which are essentially based on resemblance. Contrary to previous analyses by cognitive linguists (e.g. Lakoff & Turner 1989, Ruiz de Mendoza Ibáñez, 1998, who claim that such metaphors are based on a single mapping generally involving comparable behavioral attributes, I will argue that we have a more complex situation which involves different patterns of conceptual interaction.

    Stomach cancer is the fourth most common cancer and the second leading cause of death from cancer in the world. In Iran, this type of cancer has high rates of incidence and mortality. This study aimed to assess the survival rate of patients with stomach cancer and its determinants in Kurdistan, a province with one of the highest incidence rates of stomach cancer in the country. We studied a total of 202 patients with stomach cancer who were admitted to Tohid Hospital in Sanandaj from 2009 to 2013. Using KaplanMeier nonparametric methods the survival rate of patients was calculated in terms of different levels of age at diagnosis, gender, education, residential area, occupation, underweight, and clinical variables including tumor histology, site of tumor, disease stage, and type of treatment. In addition, we compared the survival rates using the logrank test. Finally, Cox proportional hazards regression was applied using Stata 12 and R 3.1.0 software. The significance level was set at 0.05. The mean age at diagnosis was 64.7 ± 12.0 years. The survival rate of patients with stomach cancer was 43.9% and 7% at the first and the fifth year after diagnosis, respectively. The results of logrank test showed significant relationships between survival and age at diagnosis, education, disease stage, type of treatment, and degree of being underweight (P<0.05). Moreover, according to the results of Cox proportional hazards regression model, the variables of education, disease stage, and type of treatment were associated with patient survival (P<0.05). The survival rate of patients with stomach cancer is low and the prognosis is very poor. Given the poor prognosis of the patients, it is critical to find ways for early diagnosis and facilitating timely access to effective treatment methods.

    Digestive cells are present in all metazoans and provide the energy necessary for the whole organism. Pancreatic exocrine cells are a unique vertebrate cell type involved in extracellular digestion of a wide range of nutrients. Although the organization and regulation of this cell type is intensively studied in vertebrates, its evolutionary history is still unknown. In order to understand which are the elements that define the pancreatic exocrine phenotype, we have analyzed the expression of genes that contribute to specification and function of this cell-type in an early branching deuterostome, the sea urchin Strongylocentrotus purpuratus. We defined the spatial and temporal expression of sea urchin orthologs of pancreatic exocrine genes and described a unique population of cells clustered in the upper stomach of the sea urchin embryo where exocrine markers are co-expressed. We used a combination of perturbation analysis, drug and feeding experiments and found that in these cells of the sea urchin embryo gene expression and gene regulatory interactions resemble that of bona fide pancreatic exocrine cells. We show that the sea urchin Ptf1a, a key transcriptional activator of digestive enzymes in pancreatic exocrine cells, can substitute for its vertebrate ortholog in activating downstream genes. Collectively, our study is the first to show with molecular tools that defining features of a vertebrate cell-type, the pancreatic exocrine cell, are shared by a non-vertebrate deuterostome. Our results indicate that the functional cell-type unit of the vertebrate pancreas may evolutionarily predate the emergence of the pancreas as a discrete organ. From an evolutionary perspective, these results encourage to further explore the homologs of other vertebrate cell-types in traditional or newly emerging deuterostome systems.

    We elucidated the expression of ciclosporin protein B (cyclophilin B) in stomach cancer tissue and the correlation between cyclophilin B and clinicopathological parameters, and determined the effect of cyclophilin B on growth and proliferation of stomach cancer cells. Pathological sections of stomach cancer and paracancerous tissue were collected for detecting the expression and distribution of cyclophilin B, using immunohistochemistry, and for analyzing the relationship between the expression levels of cyclophilin B in stomach cancer and the clinical pathological parameters of the patients. A cyclophilin BsiRNA lentiviral (LV-cyclophilin B-siRNA) and corresponding control vector (LV-siRNA-con) were constructed. MTT and cell cycle assays were used to detect the effect of downregulation of cyclophilin B expression on in vitro growth and proliferation and clone formation capacity of BGC823 and SGC7901 cells. The cyclophilin B-positive rate of stomach cancer tissue was 84.29% (59/70) and that of paracancerous tissue was 56.00% (28/50). The expression of cyclophilin B in stomach cancer tissue was significantly higher than that in paracancerous tissue (P stomach cancer cells, cell cycle progression, and in vivo tumorigenicity capacity. Cyclophilin B has a high diagnostic value for stomach cancer and its downregulation can effectively inhibit the growth of stomach cancer cells. Thus, cyclophilin B may be a potential therapeutic target for stomach cancer treatment.

    Purpose Treatment-related stomach cancer is an important cause of morbidity and mortality among the growing number of Hodgkin lymphoma (HL) survivors, but risks associated with specific HL treatments are unclear. Patients and Methods We conducted an international case-control study of stomach cancer nested in a cohort of 19,882 HL survivors diagnosed from 1953 to 2003, including 89 cases and 190 matched controls. For each patient, we quantified cumulative doses of specific alkylating agents (AAs) and reconstructed radiation dose to the stomach tumor location. Results Stomach cancer risk increased with increasing radiation dose to the stomach (Ptrend stomach ≥ 25 Gy and high-dose procarbazine (≥ 5,600 mg/m2) had strikingly elevated stomach cancer risk (25 cases, two controls; odds ratio [OR], 77.5; 95% CI, 14.7 to 1452) compared with those who received radiation stomach ≥ 25 Gy but procarbazine stomach cancer risk (12 cases, nine controls; OR, 8.8; 95% CI, 2.1 to 46.6), after adjustment for radiation and procarbazine doses. Conclusion Patients with HL who received subdiaphragmatic radiotherapy had dose-dependent increased risk of stomach cancer, with marked risks for patients who also received chemotherapy containing high-dose procarbazine. For current patients, risks and benefits of exposure to both procarbazine and subdiaphragmatic radiotherapy should be weighed carefully. For patients treated previously, GI symptoms should be evaluated promptly. PMID:23980092

    A 67-year-old man developed slowly progressive muscular weakness in the bilateral upper extremities (C5-7 regions) without signs of sensory deficit following the cervical radiation therapy (70.5 Gy) for right laryngeal cancer 4 years before. These clinical signs resembled those of lower motor neuron disease. MRI with gadolinium-DTPA, however, showed enhancement in the bilateral C5 and C6 anterior roots, suggesting the cervical radiculopathy due to radiotherapy. It is known that radiation to the spinal cord can lead to ''selective anterior horn cell injury''. This is the first case report of the cervical radiation radiculopathy, which, if without MRI, might be classified into selective anterior horn cell injury. Suggestion is made for the hypothesis that the spinal motoneuron loss in radiation myelopathy would be caused by retrograde degeneration due to anterior root damages. (author)

    The spectrum of this disease has undergone major changes since 1932 when Crohn, Ginzberg and Oppenheimer differentiated Ileitis terminalis from nonspecific inflammations of the bowels. Initially, Crohn assumed an inflammation restricted to the terminal ileum. Today, Crohn's disease has been verified to affect the total gastro-intestinal tract from the cavity of the mouth to the anus. In 1949 Ross et al. were the first to report Crohn's disease in the region of the stomach and duodenum. Its localization in the upper intestinal tract, however, is a rare occurrence on the whole.

    The aim of the study was to characterize CT images and stages of carcinomas localized in the antral part of the stomach obtained with spiral CT. Seven men aged from 54 years old to 81 years old inclusive, with subjective complaints and clinical suspicion of a neoplasm in the upper gastrointestinal tract were examine Examinations were performed following stomach wall re relaxation with Buscolysin.The stomach is distended by drinking 600 ml of water. Upper abdomen scans were performed with spiral CT/e General Electric with the following parameters: slice thickness 3-5 mm, spacing 3 mm, pitch 1,5, reconstruction index 3 mm. After the pre-contrast scans, 100 ml of non-ionic contrast media is administered intravenously with an injection rate of 30 ml/sec. Scan delay time - 30 seconds after start of injection. Exposition data-120 kV, 180 mAs. Carcinoma localized in the antral part of the stomach was demonstrated in 7 patients. The staging showed: I stage - one patient, II stage - 2, III stage - 1 and IV stage - three patients. According to the macro morphological characteristic: exophytic type - 4, endophytic tumor - 1, ulcerous tumor - 1 and early carcinoma - 1 patient. In our material only male patients were present. Early carcinoma was demonstrated in a male patient at an age of 80 years old. An enhancing nodular local thickness was visualized. Differential diagnosis between malignant and benign ulcer is necessary in certain cases. It is performed on the contrast scans, the malignant process enhances twice its density, When performing a purposive CT examination it is possible to diagnose neoplasms in the antral part of the stomach, from stage i to IV with different macro morphologic characteristic

    BACKGROUND: Abdominal radiotherapy for testicular cancer (TC) increases risk for second stomach cancer, although data on the radiation dose-response relationship are sparse. METHODS: In a cohort of 22,269 5-year TC survivors diagnosed during 1959-1987, doses to stomach subsites were estimated...... for 92 patients who developed stomach cancer and 180 matched controls. Chemotherapy details were recorded. Odds ratios (ORs) were estimated using logistic regression. RESULTS: Cumulative incidence of second primary stomach cancer was 1.45% at 30 years after TC diagnosis. The TC survivors who received...... radiotherapy (87 (95%) cases, 151 (84%) controls) had a 5.9-fold (95% confidence interval (CI) 1.7-20.7) increased risk of stomach cancer. Risk increased with increasing stomach dose (P-trend

    Successful pluripotent stem cell differentiation methods have been developed for several endoderm-derived cells, including hepatocytes, β-cells and intestinal cells. However, stomach lineage commitment from pluripotent stem cells has remained a challenge, and only antrum specification has been demonstrated. We established a method for stomach differentiation from embryonic stem cells by inducing mesenchymal Barx1, an essential gene for in vivo stomach specification from gut endoderm. Barx1-inducing culture conditions generated stomach primordium-like spheroids, which differentiated into mature stomach tissue cells in both the corpus and antrum by three-dimensional culture. This embryonic stem cell-derived stomach tissue (e-ST) shared a similar gene expression profile with adult stomach, and secreted pepsinogen as well as gastric acid. Furthermore, TGFA overexpression in e-ST caused hypertrophic mucus and gastric anacidity, which mimicked Ménétrier disease in vitro. Thus, in vitro stomach tissue derived from pluripotent stem cells mimics in vivo development and can be used for stomach disease models.

    Gastric tuberculosis is an extremely rare condition because of unfavorable circumstances in stomach due to low pH, high motility and lack of lymphoid tissue. All these discourage the development of tuberculosis lesion. Similarly, simultaneous stromal tumour of stomach is also a rare entity. We present a rare case of tuberculosis of stomach with no evidence of pulmonary involvement and a conceomitant stromal tumour of the stomach. This unique case illustrates the need for a high index of suspicion in order to diagnose this rare condition, as this can present in patients with no particular risk factors or minimal symptoms.

    The myelination of axons in the central nervous system (CNS) is essential for nervous system formation, function and health. CNS myelination continues well into adulthood, but not all axons become myelinated. Unlike the peripheral nervous system, where we know of numerous axon-glial signals required for myelination, we have a poor understanding of the nature or identity of such molecules that regulate which axons are myelinated in the CNS. Recent studies have started to elucidate cell behavior during myelination in vivo and indicate that the choice of which axons are myelinated is made prior to myelin sheath generation. Here we propose that interactions between axons and the exploratory processes of oligodendrocyte precursor cells (OPCs) lead to myelination and may be similar to those between dendrites and axons that prefigure and lead to synapse formation. Indeed axons and OPCs form synapses with striking resemblance to those of neurons, suggesting a similar mode of formation. We discuss families of molecules with specific functions at different stages of synapse formation and address studies that implicate the same factors during axon-OPC synapse formation and myelination. We also address the possibility that the function of such synapses might directly regulate the myelinating behavior of oligodendrocyte processes in vivo. In the future it may be of benefit to consider these similarities when taking a candidate-based approach to dissect mechanisms of CNS myelination. Copyright © 2013 IBRO. Published by Elsevier Ltd.

    Full Text Available Background. Lacrimal infections by Actinomyces are rare and commonly misdiagnosed for long periods of time. They account for 2% of all lacrimal diseases. Case Report. We report a case of a 70-year-old female patient suffering from a para-canalicular abscess in the medial canthus of the left eye, beside the lower punctum lacrimale, resembling a chalazion. Purulence exited from the punctum lacrimale due to inflammation of the inferior canaliculus (canaliculitis. When pressure was applied to the mass, a second exit of purulence was also observed under the palpebral conjunctiva below the lacrimal caruncle. A surgical excision was performed followed by administration of local antibiotic therapy. The histopathological examination of the extracted mass revealed the existence of actinomycosis. Conclusion. Persistent or recurrent infections and lumps of the eyelids should be thoroughly investigated. Actinomyces as a causative agent should be considered. Differential diagnosis is broad and should include canaliculitis, chalazion, and multiple types of neoplasias. For this reason, in nonconclusive cases, a histopathological examination should be performed.

    Coffin-Siris syndrome is a multiple congenital anomaly/mental retardation syndrome with phenotypic variability [OMIM 135900]. The diagnosis is based solely on clinical findings, as there is currently no molecular, biochemical, or cytogenetic analysis available to confirm a diagnosis. Although typically described as an autosomal recessive disorder, autosomal dominant inheritance has also been infrequently reported. We describe a mother and her two daughters who all have features that resemble Coffin-Siris syndrome. However, this is not a completely convincing diagnosis given that hypertelorism is not a feature of Coffin-Siris syndrome and the family is relatively mildly affected. Yet, this family provides further evidence of an autosomal dominant mode of inheritance for a likely variant of Coffin-Siris syndrome (at least in some families). In addition, Sibling 1 had premature thelarche. She is the second reported individual within the spectrum of Coffin-Siris syndrome to have premature thelarche, indicating that it may be a rare clinical feature. Copyright 2006 Wiley-Liss, Inc.

    Full Text Available Atypical mycobacterial (AM infection is caused by Mycobacterium species other than M.tuberculosis. AM skin infection has clinical manifestations that resemble M. tuberculosis infection and deep fungal infection. Laboratory workup is necessary to confirm the diagnosis. An 83-year old female came with a painful lump and swelling on her right lower extremity since three months before admission. Physical examination revealed a plaque consisting, of multiple erythematous and hyperpigmented papules and nodules, diffuse erythematous lesion, and shallow ulcers partially covered with pus and crust. Histopathological features showed tuberculoid granuloma. Direct test and periodic acid-Schiff (PAS staining of the skin biopsy found no fungal element nor acid-fast bacilli (AFB. Culture and polymerase chain reaction (PCR of M. tuberculosis were negative. The working diagnosis was atypical mycobacterial infection and treatment with 450 mg rifampicin and 100 mg minocycline daily were administered accordingly. In two months observation following the treatment, the pain was no longer exist, the ulcers were completely healed, and some nodules were in the process of healing Among other Mycobacterium spp, M.marinum is the most common cause of AM infrections. Clinical manifestation of M. marinum infection may present as solitary or multiple nodules on the hands, feet, elbows and knees with sporotrichoid spreading patern. The diagnosis of AM was established based on clinical and laboratory examination. The diagnosis was also confirmed by good clinical response to minocycline and rifampicin.

  11. Serrated adenoma of stomach: A premalignancy?

    2015-01-01

    Full Text Available Serrated adenoma is a newly described entity in the group of gastric adenomas. Until date only 20 cases of gastric serrated adenoma have been reported. It is an important entity to be diagnosed accurately as it has a very high-risk of malignant transformation, especially those located in the cardia of stomach. Serrated adenoma associated with adenocarcinoma is more frequent in the elderly, but pure serrated adenoma is common in the young, in whom follow-up is mandatory. Gastric serrated adenoma has distinct location, definite histomorphology and characteristic Ki-67 immunohistochemical staining. Ki-67 staining helps to differentiated pure serrated adenoma from those associated with adenocarcinoma. We present a young adult male, incidentally detected to have gastric serrated adenoma.

    One thousand five hundred and eighty-three patients who were x-rayed for dyspepsia showed varioliform erosions in 15.3%. Men had an incidence of 9.8%, almost twice as common as in women (5.5%). Mucosal polyps, usually of the hyperplastic type, occurred in 2.4%. 15% of patients with gastric ulcers and 16% of patients with duodenal ulcers had varioliform erosions. On the other hand, amongst patients with erosions, 11% had gastric ulcers and 8.3% duodenal ulcers. The definitions of erosion which have been given in the literature are partly contradictory, and are discussed. Varioliform erosions, also known as complete erosions, may be acute or chronic. They are the third most common cause of bleeding from the upper gastrointestinal tract. With modern radiological methods of examining the stomach, they are no longer a rare finding. (orig.) [de

    Cancer can develop in the operated stomach after partial gastrectomy and in the reconstructed gastric tube after surgery for esophageal cancer. It is considered that endoscopic therapy is more safe and suitable for the early gastric cancer developed in such stomach than operation. We investigated the efficacy of endoscopic submucosal dissection (ESD) for cancer of the operated stomach. Subjects were 669 gastric cancer patients who underwent ESD: 22 patients (23 lesions) had surgically altered gastric anatomy, whereas 647 patients (727 lesions) had normal gastric anatomy. In the altered gastric anatomy group, 13 patients, 6 patients, and 3 patients had previously undergone distal gastrectomy, gastric tube reconstruction, and proximal gastrectomy, respectively. Rates of complete en bloc resection and curative resection were compared between the two groups. Influence of an anastomotic site and/or a suture line on ESD outcomes was examined in the altered gastric anatomy group. The rate of complete en bloc resection by ESD was 82.6% (19/23 lesions) in the altered gastric anatomy group and 92.3% (671/727 lesions) in the normal gastric anatomy group. The rate of curative resection and incident rates of complications were not significantly different between the groups. In the altered gastric anatomy group, the rate of complete en bloc resection was significantly lower when a lesion had spread across an anastomotic site and/or a suture line (P = 0.0372). Furthermore, duration of ESD was significantly longer (P = 0.0276), and resection efficiency was significantly lower (13 mm(2)/min, P = 0.0283), when treating lesions with an anastomotic site and/or a suture line than when treating isolated lesions. Outcome of ESD for cancer of the operated stomach compares with that in normal stomach anatomy. Anastomotic site/suture line within a lesion influenced the ESD procedure.

    2016-01-01

    Aim and objective: It is argued whether general radiographic examinations adhere to a person-centred approach within the direct digital radiography (DDR) environment. General radiographic examinations continue to increase and constitute approximately 90% of all examinations undertaken in the clinical environment. This study explored the potential impact patients experience whilst undergoing general imaging examinations. Method: An ethnographic methodology provided insight of two general radiography environments in the United Kingdom (UK) using participant observation and semi-structured interviews. Findings: The findings highlighted an ‘in and out’ culture whereby patients are ‘hurried’ and ‘rushed’ out of X-ray rooms in response to increasing time pressures experienced by diagnostic radiographers. In addition, this study challenged that patients may begin to rank ‘speed’ and ‘waiting times’ above other elements of radiographic care thus presenting new challenges for radiographers within the clinical environment. Conclusion: It is asserted that radiographers should remain holistic healthcare professionals and not begin to resemble operators on the production line. Further, it challenges whether patients are beginning to rank aspects of radiographic care within contemporary practices. Advances in knowledge: Few studies have explored the radiographer–patient relationship within the DDR environment, yet this study provides insight of person-centred practices within contemporary practices. - Highlights: • Challenges whether the use of DDR conforms to a person-centred approach. • Challenges whether radiographers are ‘treating patients as persons’ using DDR. • Patients may begin to rank ‘speed’ and ‘waiting times’ above other aspects of radiographic care.

  19. Predator-Resembling Aversive Conditioning for Managing Habituated Wildlife

    Full Text Available Wildlife habituation near urban centers can disrupt natural ecological processes, destroy habitat, and threaten public safety. Consequently, management of habituated animals is typically invasive and often includes translocation of these animals to remote areas and sometimes even their destruction. Techniques to prevent or reverse habituation and other forms of in situ management are necessary to balance ecological and social requirements, but they have received very little experimental attention to date. This study compared the efficacy of two aversive conditioning treatments that used either humans or dogs to create sequences resembling chases by predators, which, along with a control category, were repeatedly and individually applied to 24 moderately habituated, radio-collared elk in Banff National Park during the winter of 2001-2002. Three response variables were measured before and after treatment. Relative to untreated animals, the distance at which elk fled from approaching humans, i.e., the flight response distance, increased following both human and dog treatments, but there was no difference between the two treatments. The proportion of time spent in vigilance postures decreased for all treatment groups, without differences among groups, suggesting that this behavior responded mainly to seasonal effects. The average distance between elk locations and the town boundary, measured once daily by telemetry, significantly increased for human-conditioned elk. One of the co-variates we measured, wolf activity, exerted counteracting effects on conditioning effects; flight response distances and proximity to the town site were both lower when wolf activity was high. This research demonstrates that it is possible to temporarily modify aspects of the behavior of moderately habituated elk using aversive conditioning, suggests a method for reducing habituation in the first place, and provides a solution for Banff and other jurisdictions to manage

    This study examined the results of surgical treatment of 90 patients with ulcerative stenosing disease of the stomach and duodenal ulcer between 1984 and 1995. 30 patients (study group) underwent stomach Roux resection. Truncal vagotomy with stomach Bilroth-I resection (control group) was made in 20 patients, 20 patients had a truncal vagotomy with pyloroplasty according to Heineke-Mikulicz (control group), and 20 patients had a selective proximal vagotomy with gastroduodenostomy by Joboulay (control group). Motor and evacuation functions of gallbladder were assessed by dynamic US and radioisotope scintigraphy. After a Roux stomach resection and a stomach Bilroth-I resection, respectively, hypokinetic and hyperkinetic types of the gallbladder's dyskinesia was established. After a selective proximal vagotomy with gastroduodenostomy by Joboulay and truncal vagotomy with pyloroplasty according to Heineke-Mikulicz essential change of the gallbladder refractive function wasn't observed.

    Treatment-related stomach cancer is an important cause of morbidity and mortality among the growing number of Hodgkin lymphoma (HL) survivors, but risks associated with specific HL treatments are unclear. We conducted an international case-control study of stomach cancer nested in a cohort of 19,882 HL survivors diagnosed from 1953 to 2003, including 89 cases and 190 matched controls. For each patient, we quantified cumulative doses of specific alkylating agents (AAs) and reconstructed radiation dose to the stomach tumor location. Stomach cancer risk increased with increasing radiation dose to the stomach (Ptrend < .001) and with increasing number of AA-containing chemotherapy cycles (Ptrend = .02). Patients who received both radiation to the stomach ≥ 25 Gy and high-dose procarbazine (≥ 5,600 mg/m(2)) had strikingly elevated stomach cancer risk (25 cases, two controls; odds ratio [OR], 77.5; 95% CI, 14.7 to 1452) compared with those who received radiation < 25 Gy and procarbazine < 5,600 mg/m(2) (Pinteraction < .001). Risk was also elevated (OR, 2.8; 95% CI, 1.3 to 6.4) among patients who received radiation to the stomach ≥ 25 Gy but procarbazine < 5,600 mg/m(2); however, no procarbazine-related risk was evident with radiation < 25 Gy. Treatment with dacarbazine also increased stomach cancer risk (12 cases, nine controls; OR, 8.8; 95% CI, 2.1 to 46.6), after adjustment for radiation and procarbazine doses. Patients with HL who received subdiaphragmatic radiotherapy had dose-dependent increased risk of stomach cancer, with marked risks for patients who also received chemotherapy containing high-dose procarbazine. For current patients, risks and benefits of exposure to both procarbazine and subdiaphragmatic radiotherapy should be weighed carefully. For patients treated previously, GI symptoms should be evaluated promptly.

    BACKGROUND Stomach cancer was a leading cause of cancer-related deaths early in the 20th century and has steadily declined over the last century in the United States. Although incidence and death rates are now low, stomach cancer remains an important cause of morbidity and mortality in black, Asian and Pacific Islander, and American Indian/Alaska Native populations. METHODS Data from the CONCORD-2 study were used to analyze stomach cancer survival among males and females aged 15 to 99 years who were diagnosed in 37 states covering 80% of the US population. Survival analyses were corrected for background mortality using state-specific and race-specific (white and black) life tables and age-standardized using the International Cancer Survival Standard weights. Net survival is presented up to 5 years after diagnosis by race (all, black, and white) for 2001 through 2003 and 2004 through 2009 to account for changes in collecting Surveillance, Epidemiology, and End Results Summary Stage 2000 data from 2004. RESULTS Almost one-third of stomach cancers were diagnosed at a distant stage among both whites and blacks. Age-standardized 5-year net survival increased between 2001 to 2003 and 2004 to 2009 (26.1% and 29%, respectively), and no differences were observed by race. The 1-year, 3-year, and 5-year survival estimates were 53.1%, 33.8%, and 29%, respectively. Survival improved in most states. Survival by stage was 64% (local), 28.2% (regional), and 5.3% (distant). CONCLUSIONS The current results indicate high fatality for stomach cancer, especially soon after diagnosis. Although improvements in stomach cancer survival were observed, survival remained relatively low for both blacks and whites. Primary prevention through the control of well-established risk factors would be expected to have the greatest impact on further reducing deaths from stomach cancer. PMID:29205310

    Although cardiac cancer of the remnant stomach and primary cardiac cancer both occur in the same position, their clinical characteristics and outcomes have not been compared previously. The objective of this study was designed to evaluate the prognosis of cardiac cancer of the remnant stomach in comparison with primary cardiac cancer. In this retrospective comparative study, clinical data and prognosis were compared in 48 patients with cardiac cancer of the remnant stomach and 96 patients with primary cardiac cancer who underwent radical resection from January 1995 to June 2007. Clinicopathologic characteristics, survival times, mortality, and complications were analyzed. The 5-year survival rate was significantly higher in patients with primary cardiac cancer than in those with cardiac cancer of the remnant stomach (28.4% vs. 16.7%, P = 0.035). Serosal invasion, lymph node metastasis and tumor location were independent prognostic factors for survival. Subgroup analysis, however, showed similar survival rates in patients with primary cardiac cancer and cardiac cancer of the remnant stomach without serosal invasion (25.0% vs. 43.8%, P = 0.214) and without lymph node metastasis (25.0% vs. 38.8%, P = 0.255), as well as similar complication rates (20.8% vs. 11.5%, P = 0.138). Although the survival rates after radical resection in patients with cardiac cancer of the remnant stomach were poorer than in those with primary cardiac cancer, they were similar in survival rates when patients without serosal invasion or lymph node metastasis. Therefore, early detection is an important way to improve overall survival in cardiac cancer of the remnant stomach.

    Abdominal radiotherapy for testicular cancer (TC) increases risk for second stomach cancer, although data on the radiation dose-response relationship are sparse. In a cohort of 22,269 5-year TC survivors diagnosed during 1959-1987, doses to stomach subsites were estimated for 92 patients who developed stomach cancer and 180 matched controls. Chemotherapy details were recorded. Odds ratios (ORs) were estimated using logistic regression. Cumulative incidence of second primary stomach cancer was 1.45% at 30 years after TC diagnosis. The TC survivors who received radiotherapy (87 (95%) cases, 151 (84%) controls) had a 5.9-fold (95% confidence interval (CI) 1.7-20.7) increased risk of stomach cancer. Risk increased with increasing stomach dose (P-trendstomach increased gastric cancer risk for several decades, with the highest risks after stomach doses of ⩾30 Gy. Clinicians should be aware of these excesses when previously irradiated TC survivors present with gastrointestinal symptoms and when any radiotherapy is considered in newly diagnosed TC patients.

    Gastrointestinal stromal tumour (GIST), within its definition, is a gastrointestinal (GI) mesenchymal tumour containing spindle cells and showing CD 117 immunopositivity. The incidence of GISTs is estimated at 10-20/million. GISTs occur typically in people over 50 years of age. Over 95% of primary GISTs are solitary. Rarely, GISTs are multifocal and occur in young adults and children. A case of a 60-year-old women with double GIST of the stomach is reported here. The patient approached her general practitioner because of stomach ache, chronic diarrhoea and weight loss. Ultrasonography showed an abdominal tumour. During gastroscopy a submucosal tumour in the antral part of the stomach was found. Computed tomography revealed a pathological lesion between the stomach and the liver and an intramural tumour of the stomach. Two stomach tumours were found, and a Bilroth I gastrectomy was performed. Histopathological examination showed GIST in both tumours. This case shows that multifocal GISTs of the stomach can arise in older patients.

    Although spouses strongly resemble one another in their risk for alcohol use disorder (AUD), the causes of this association remain unclear. To examine longitudinally, in first marriages, the association of a first registration for AUD in one spouse with risk of registration in his or her partner and to explore changes in the risk for AUD registration in individuals with multiple marriages as they transition from a spouse with AUD to one without or vice versa. Population-wide Swedish registries were used to identify individuals born in Sweden between 1960 and 1990 who were married before the end of study follow-up on December 31, 2013. The study included 8562 marital pairs with no history of AUD registration prior to their first marriage and an AUD registration in 1 spouse during marriage and 4891 individuals with multiple marriages whose first spouse had no AUD registration and second spouse did or vice versa. Final statistical analyses were conducted from August 15 to September 1, 2017. A spousal onset or history of AUD registration. Alcohol use disorder registration in national medical, criminal, or pharmacy registries. Among the 8562 marital pairs (5883 female probands and 2679 male probands; mean [SD] age at marriage, 29.2 [5.7] years) in first marriages, the hazard ratio of AUD registration in wives immediately after the first AUD registration in their husbands was 13.82, which decreased 2 years later to 3.75. The hazard ratio of AUD registration in husbands after the first AUD registration in their wives was 9.21, which decreased 2 years later to 3.09. Among the 4891 individuals with multiple marriages (1439 women and 3452 men; mean [SD] age at first marriage, 25.5 [4.2] years), when individuals transitioned from a first marriage to a spouse with AUD to a second marriage to a spouse without AUD, the hazard ratio for AUD registration was 0.50 (95% CI, 0.42-0.59) in women and 0.51 (95% CI, 0.44-0.59) in men. After a first marriage to a spouse without AUD, the

Less than 200 case reports have been documented in literature so far. Herein, we report a 26-year-old otherwise healthy female patient who presented with a 1-month history of epigastric pain. On physical examination, a palpable, slightly mobile, and tender epigastric mass was detected. All laboratory tests were normal. A chest, abdominal, and pelvic contrast-enhanced computed tomography (CT scans showed a 3.8 × 7.2 × 8.7 cm ill-defined mass, involving gastric fundus and extending into gastric cardia and lower gastroesophageal junction. It was associated with multiple enlarged gastrohepatic lymph nodes; the largest measured 1.2 cm. There was no evidence of ascites or retroperitoneal or mesenteric lymphatic metastases. Patient underwent total gastrectomy with D2 lymphadenectomy, splenectomy, and antecolic Roux-en-Y esophagojejunal anastomosis. Histopathological examination revealed coexpression of mesenchymal, epithelial, and neural markers. The characteristic chromosomal translocation (t(11; 22(p13; q12 was demonstrated on fluorescence in situ hybridization (FISH technique. Diagnosis of DSRCT of stomach was confirmed. Patient received no postoperative radiotherapy or chemotherapy. A postoperative 3-month followup failed to show any recurrence. In addition, a literature review on DSRCT is included.

    In the search for microfossils of early life on Earth, the demonstration of biogenicity is paramount. Traditionally, only syngenetic structures with cellular elaboration, hollow sheaths/cell walls, and indigenous kerogen have been considered bona fide fossils. Recent reports of inorganically preserved microfossils represent a shift from this practice. Such a shift, if accompanied by a robust set of biogenicity criteria, could have profound implications for the identification of biosignatures on early Earth and extraterrestrial bodies. Here, we reaffirm the conventional criteria by examining aggregates of inorganic filaments from the Pilbara region of Western Australia. These aggregates are preserved in bedded chert, and the filaments measure up to 1 μm in diameter and 100 μm in length. The aggregates superficially resemble kerogenous microbial fabrics and mycelial organisms. However, the filaments consist of manganese oxide, lack cellular elaboration, and show no evidence for hollow sheaths or cell walls. We conclude that the filaments are fibrous minerals of abiotic origin. The similarities between these pseudofossils and some filamentous fossils highlight the need for strict application of the conventional criteria for recognizing microfossils. In the absence of kerogen, morphologically simple structures should, at least, show evidence of cellular features to be considered bona fide fossils.

    Full Text Available An 82-year-old man presented with upper gastrointestinal bleeding. A polypoid lesion of the distal stomach with focal ulceration was seen at endoscopy. This was treated by a partial gastrectomy. The resected stomach contained two separate tumours near the pylorus: a gastrointestinal stromal tumour (GIST and an adjacent lipoma. The literature includes case reports of synchronously occurring GIST and adenocarcinoma, GIST and mucosa-associated lymphoid tissue lymphoma and GIST and carcinoid tumour. Herein is the first case report of two distinct mesenchymal tumors coexisting in the stomach.

    Incidence of gastric ulcer is high in almost all countries of the world. On the development and course of the disease affect the state acid- and enzymes production stomach, immune status. The purpose was to determine the presence and power of correlative links secretory activity of the stomach and immune changes in the peripheral blood during exacerbation of ulcer disease stomach. Surveyed in obtaining informed consent 42 patients with gastric ulcer in the acute phase prior to the eradication and antisecretory therapy and 40 healthy volunteers. On the state of function acid- and enzymes production of the gastric mucosa judged by the results of a 2-hour intragastric pH-metry and serum concentration pepsinogen, gastrin before the start of active treatment. Immunophenotype lymphocytes on CD-antigens (CD3, CD4, CD8, CD16, CD19, CD45, CD56) was measured by immunofluorescence, levels immunoglobulin isotype M, G, A, E - ELISA method. When short-term intragastric pH-metry of the stomach hyperacidity patients recorded 6.7 times more likely than healthy, normacidity - 12.3 times less. Reduction of acid production was observed up to 8.6 times more, indicating the development of mucosal atrophy. Basal pH in the antrum was lower by 54.5% than in the control group, with stimulation increased by 33.6%, but remained lower than the values of healthy individuals by 48.7%. When ELISA amount pepsinogen patients showed significant increase in serum levels of PG-I relative to the control group at 33.4%, PG-II - 52%. In assessing the immune status of patients were identified changes in system phagocytes, cellular and humoral links, most pronounced for severe current peptic ulcer disease. The results indicate the presence of positive and negative correlative links mild to moderate force between indicators of secretory activity of gastric mucosal innate and adaptive immunity in patients with acute exacerbation of peptic ulcer disease.

    This study aimed to show reconstruction of the fetal stomach using the HDlive rendering mode in ultrasound. Seventeen healthy singleton fetuses at 18-34 weeks' gestational age were observed using the HDlive rendering mode of ultrasound in utero. In all of the fetuses, we identified specific spatial structures, including macroscopic anatomical features (e.g., the pyrous, cardia, fundus, and great curvature) of the fetal stomach, using the HDlive rendering mode. In particular, HDlive rendering images showed remarkably fine details that appeared as if they were being viewed under an endoscope, with visible rugal folds after 27 weeks' gestational age. Our study suggests that the HDlive rendering mode can be used as an additional method for evaluating the fetal stomach. The HDlive rendering mode shows detailed 3D structural images and anatomically realistic images of the fetal stomach. This technique may be effective in prenatal diagnosis for examining detailed information of fetal organs.

    Despite the reduced incidence of gastric cancer in the developed world, a diagnosis of stomach carcinoma still carries a poor prognosis due to the asymptomatic nature of the disease in the early stages, subsequent advanced stage diagnosis, and a low 5 year survival rate. Endoscopy remains the primary standard for diagnosis of stomach carcinoma and the current marker, carbohydrate antigen 19-9 (CA19-9) lacks the levels of sensitivity and specificity required in order to make it clinically useful for diagnostic monitoring. Therefore, there is a current need for additional markers to improve the diagnostic accuracy for the early stages of stomach cancer. Together, glycomic, proteomic, and glycoproteomic analyses of serum have the potential to identify such probable markers. A discovery study is reported here using preoperative serum from 80 stomach cancer patients, 10 patients bearing benign stomach disease, and 20 matched controls. Glycomic analysis of the total and immunoaffinity depleted serum revealed statistically significant increases in the levels of sialyl Lewis X epitopes (SLe(X)) present on triantennary glycans accompanied by increased levels of core fucosylated agalactosyl biantennary glycans present on IgG (referred to as the IgG G0 glycoform) which are associated with increasing disease pathogenesis. Protein expression analysis using 2D-DiGE returned a number of differentially expressed protein candidates in the depleted serum, many of which were shown to carry triantennary SLe(X) during subsequent glycomic investigations. Biological pathway analysis of the experimental data returned complement activation and acute phase response signaling as the most significantly altered pathways in the stomach cancer patient serum. Upon the basis of these findings, it is suggested that increased expression of IgG G0 and complement activation are a host response to the presence of the stomach tumor while the increased expression of SLe(X) and acute phase response

    The technique for examining surgical resection margins described in the Japanese Classification of Gastric Carcinoma is based on the examination of continuous infiltration by the primary tumor, and discontinuous lesions such as multiple cancers are not examined. However, examining lesions-particularly cancers-at the resection margins is important for the prevention of cancers in the remaining stomach that result from cancer remnants (remnant gastric cancer). The clinical usefulness of a simple pathological examination technique for detecting cancer located at the surgical margin of the stomach was studied. A specimen 5-8 mm wide was resected from the surgical cut margin along the entire circumference of the stomach. When the pathological margin was positive for cancer, the surgical margin was also examined, and cases that were positive for cancer were regarded as marginally positive. Of the 1,498 patients with early gastric cancer who were examined using this method, 17 (1.1 %) were marginally positive for multiple cancers, and 8 of these 17 patients (57 %) had microcancers cancer involving the surgical margin, which occurs at a rate of 1.1 %, making it possible to prevent remnant gastric cancer by reoperation.

    Stomach cancer, the fourth most common cancer and the second leading cause of cancer-related death through the world, is very common in parts of Iran. Geographic variation in the incidence of stomach cancer is due to many different factors. The aim of this study was to assess the geographical and spatial distribution of stomach cancer in Iran using data from the cancer registry program in Iran for the year 2009. The reported incidences of stomach cancer for different provinces were standardized to the world population structure. ArcGIS software was used to analyse the data. Hot spots and high risk areas were determined using spatial analysis (Getis-Ord Gi). Hot and cold spots were determined as more than or less than 2 standard deviations from the national average, respectively. A significance level of 0.10 was used for statistical judgment. In 2009, a total of 6,886 cases of stomach cancers were reported of which 4,891 were in men and 1,995 in women (standardized incidence rates of 19.2 and 10.0, respectively, per 100,000 population). The results showed that stomach cancer was concentrated mainly in northwest of the country in both men and women. In women, northwest provinces such as Ardebil, East Azerbaijan, West Azerbaijan, Gilan, and Qazvin were identified as hot spots (pstomach cancer is clustered in the northwest of the country, further epidemiological studies are needed to identify factors contributing to this concentration.

    Stomach cancer is an aggressive malignancy that is difficult to detect at an early stage and therefore is characterized by poor survival rates. Over the last two decades, there has been no report of gastric cancer survival in Khon Kaen province, Thailand. The aim of this retrospective cohort study was to provide up-to-date information about the survival of gastric cancer patients in this province. Data from Khon Kaen population-based cancer registry, Faculty of Medicine, Khon Kaen University were newly obtained on 650 patients who were diagnosed with stomach cancer during the period 1 January, 2000 to 31 December, 2012. These were then followed up until death or the end of the study (31 December 2014). We calculated the observed survival with the actuarial life table method, and relative survival, defined as the ratio of observed survival in the group of the stomach cancer patients to the expected survival in the entire Thai population from the estimated generation life tables for Thailand of five-year birth cohorts from 1900 - 2000. The 5 year observed and 5 year relative survival rates were 17.2 % (95% CI: 13.54-21.14) and 18.2 % (95% CI: 14.3-22.4), respectively. The highest 5 year relative survival rates were demonstrated among patients aged 45-65, with stage I or II lesions, with adenocarcinomas, with a body of stomach location, well differentiated and receiving surgery and/or chemotherapy. The observed and relative survival rates were close to each other. Our findings provide basic information beneficial to development of an effective treatment system and appropriately improved population-based cancer registration.

    The study of complex regional pain syndrome (CRPS) in humans is complicated by inhomogeneities in available study cohorts. We hoped to characterize early CRPS-like features in patients undergoing hand surgery. Forty-three patients were recruited from a hand surgery clinic that had elective surgeries followed by cast immobilization. On the day of cast removal, patients were assessed for vasomotor, sudomotor, and trophic changes, and edema and pain sensitization using quantitative sensory testing. Pain intensity was assessed at the time of cast removal and after 1 additional month, as was the nature of the pain using the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS). Skin biopsies were harvested for the analysis of expression of inflammatory mediators. We identified vascular and trophic changes in the surgical hands of most patients. Increased sensitivity to punctate, pressure, and cold stimuli were observed commonly as well. Moreover, levels of IL-6, TNF-alpha, and the mast cell marker tryptase were elevated in the skin of hands ipsilateral to surgery. Moderate-to-severe pain persisted in the surgical hands for up to 1 month after cast removal. Exploratory analyses suggested interrelationships between the physical, quantitative sensory testing, and gene expression changes and pain-related outcomes. This study has identified CPRS-like features in the limbs of patients undergoing surgery followed by immobilization. Further studies using this population may be useful in refining our understanding of CRPS mechanisms and treatments for this condition. Published by Elsevier Inc.

E-mail: radiovet@ufrrj.br The equine gastric ulcer syndrome (EGUS includes all symptomatic or asymptomatic cases of erosions, ulcers, gastritis, gastric emptying disorders, duodenitis, duodenal ulcers and complications of these disorders. Occupies a prominent place in the equine clinic where you can go for the death of the animal. Ultrasonography of the stomach is indicated when the animals showed clinical signs of gastric disease. The aim of this study was to describe the sonographic evaluation and macroscopic pathological findings of the stomach of adult horses intended for commercial slaughter. To this 39 intended for commercial slaughter horses were evaluated. Sonographic evaluation before slaughter transabdominal via the left side of abdomen for evaluation of the stomach was performed. After the slaughter of these animals their stomachs were collected, evaluated and photographed. The study concluded that ultrasonography identified the stomach in all animals evaluated, but did not allow a careful evaluation of the entire length of the viscera, especially the aglandular region and pleated border. All animals evaluated had injury to the gastric mucosa in different degrees. In animals evaluated, the stomach region was most affected by injuries glandular region, although the most severe lesions have been found in the ruffled border adjacent to aglandular region.

    The human stomach is a formidable barrier to orally ingested microorganisms and was long thought to be sterile. The discovery of Helicobacter pylori, a carcinogenic bacterial pathogen that infects the stomach mucosa of more than one half of all humans globally, has started a major paradigm shift in our understanding of the stomach as an ecological niche for bacteria. The special adaptations that enable H. pylori to colonize this well-protected habitat have been intensively studied over the last three decades. In contrast, our knowledge concerning bacteria other than H. pylori in the human stomach is still quite limited. However, a substantial body of evidence documents convincingly that bacteria can regularly be sampled from the stomachs of healthy adults. Commonly detected phyla include Firmicutes, Actinobacteria, Bacteroidetes, and Proteobacteria, and characteristic genera are Lactobacillus, Streptococcus, and Propionibacterium. In this review, we summarize the available literature about the gastric microbiota in humans and selected model animals, discuss the methods used in its characterization, and identify gaps in our knowledge that need to be addressed to advance our understanding of the bacterial colonization of the different layers of the gastric mucosa and its potential role in health and disease. © 2013 Federation of European Microbiological Societies.

    To identify the patterns and the correlation of morphological and functional changes in stomach wall with the dynamics of different types of acute intestinal obstruction. The study was performed on 33 adult mongrel dogs of both genders weighing 17-20 kg. All researches were conducted in accordance with the documents, such as the 'Guide for the Care and Use of laboratory animals of the National Institute of Health (National Institute of Health - NIH, Bethesda, USA)' and 'Rules of work with experimental animals'. The same methods were used to study the morphology of stomach wall in normal conditions and after intestinal obstruction simulation. We used H & E stain, Van Gieson's picrofuchsin staining combined with Mallory. The choice of histochemical methods was determined by the need to study metabolic processes in epithelial cells and gastric mucosa glands. Einarson method for detecting total nucleic acids was used. The last group of methods was statistical analysis. We determined the regularities of structural organization of microcirculation in various parts of the stomach, the correlation of morphological and functional changes in stomach wall with the dynamics of different types of acute intestinal obstruction. Our data indicate proximal-distal gradient of gastric perfusion: the most pronounced vascular network and maximum blood flow are observed in proximal stomach in both normal conditions and acute intestinal obstruction. More tenuous and reduced blood flow was revealed in the antrum, that is morphological basis of the most frequent localization of acute ulcers in this department.

    Available are the results of surgical treatment of 90 patients with stenotic gastroduodenal ulcer in Burdenko Surgical Faculty Hospital of Sechenov Moscow Medical Academy between 1984 and 1985. 30 patients (study group) underwent stomach Roux-type resection. Truncal vagotomy with a stomach Bilroth-I resection was made in 20 control patients, after 20 control patients had a truncal vagotomy with pyloroplasty according to Heineke-Mikulicz, and 20 patients had selective proximal vagotomy with gastroduodenostomy by Joboulay (the third control group). Exocrine function of the pancreas was assessed by serum concentration of immunoreactive trypsin, endocrine function by fasting blood sugar, oral glucose tolerance and serum concentration of immunoreactive insulin. The authors came to the conclusion that exocrine function of the pancreas was equally damaged in patients with a Roux stomach resection, stem vagotomy with a stomach Bilroth-I resection and a stem vagotomy with pyloroplasty Heineke-Mikulicz. After selective proximal vagotomy a level of immunoreactive trypsin was normal. After a Roux stomach resection relative incompetence of basophil cells of the pancreas and long increase of insulin in the blood were observed but without influence on the glucose curve. The changes of glucose curve and level of immunoreactive insulin were similar in the control groups.

    The article deals with evaluation findings of diagnostic possibilities of gastroscintigraphy in assessment of motoric evacuatory function of the stomach in case of pathology of various origin. Gastroscintigraphy was conducted for 122 patients (56 men and 66 women) aged from 18 to 72 with different gastroduodenal pathology (functional dyspepsia, chronic gastritis, chronic cholecystitis, ulcer of the stomach and duodenum. Radiopharmaceutical agent 99 mTc-pertechnetate with activity of 1 MBq/kg was applied. Impaired motoric evacuatory function of the stomach was observed in 63 patients: regarding hypotonic type in most patients with functional dyspepsia (13.3%) and with chronic gastritis (19.8%); according to hypertonic type - 32 patients, mainly with functional dyspepsia (9.8%) and gastric ulcer (6.6%). Increased motoric evacuatory function of the stomach was revealed in 40 patients: with functional dyspepsia (14.8%) and in gastric ulcer (16.4%). The gastroesophageal reflux was observed in 59 patients and duodenogastric one - in 36 patients. Therefore, gastroscintigraphy in assessment of motoric evacuatory function of the stomach can completely replace X-ray examination.

    Laparoscopic surgery for gastric cancer has become extremely widespread in recent years especially in Asian countries due to its low invasiveness. As to evidence of indication for laparoscopic surgery for gastric cancer, laparoscopic surgery for gastric cancer often appears to be indicated for early gastric cancer at many institutions, while evidence was considered to be insufficient to recommend laparoscopic surgery for gastric cancer at Stage II and above. There are also problems with indications for cases other than tumour factors. No meta-analyses and prospective studies have been reported, but outcomes of laparoscopic surgery for gastric cancer in gastric cancer patients with co-morbid and/or existing diseases have been reported in retrospective studies. Indications in the elderly appear to be favourable in terms of post-operative ambulation considering factors such as the degree of dissection in accordance with the status of the patient. Meta-analyses, randomized controlled trials and several retrospective studies have compared the short-term usefulness of laparoscopic surgery for gastric cancer with that of conventional gastrectomy. The superiority of laparoscopic surgery for gastric cancer has been reported in terms of the reduced amount of bleeding, a reduction in the administration frequency and period of analgesic doses, a reduction in the duration of fever, early recovery of intestinal movement and early return to oral intake. A small-scale randomized controlled trial and several retrospective studies have demonstrated no significant differences in survival rate, recurrence rate and type of recurrence between laparoscopic surgery for gastric cancer and conventional gastrectomy. The results of the aforementioned trials in early gastric cancer in Japan and Korea for which enrolment is complete remain to be published. © The Author 2016. Published by Oxford University Press.

    This study is focused on the vascular anatomy of the stomach in relation to the gastric pull-up construction. The vascular anatomy was studied on forty-one human specimens. We find out the differences in blood supplement between anterior and posterior wall. It was maked an review of the main trunk arteries of the stomach. To display the vessels of the stomach we used diaphanoscopy, digital shooting in special mode and micro preparation of the vessels. We find out that left gastric artery gives more branches to the posterior wall and right gastroepiploic artery (RGEA) gives more branches to the anterior wall. But brunches of RGEA are longer on the posterior wall than on the anterior. Also we are offering the new classification of the RGEA related to gastric pull-up construction. This classification based not only on the anatomical shapes of RGEA but on the properties of the flow dynamics through the artery.

    In the following article, we will discuss general issues relating to acute and late gastric's radiation toxicities. The tolerance of the stomach to complete or partial organ irradiation is more un-appreciated than for most other organs. We consulted the Medline database via PubMed and used the key words gastric - radiotherapy - toxicity. Currently, 60 Gy or less is prescribed in gastric radiation therapy. Acute clinical toxicity symptoms are predominantly nausea and vomiting. Although there is a general agreement that the whole stomach tolerance is for doses of 40 to 45 Gy without unacceptable complication, it is well established that a stomach dose of 35 Gy increases the risk of ulcer complications.

    Full Text Available Abstract Background Taurine has chemical structure similar to an inhibitory neurotransmitter, γ-aminobutyric acid (GABA. Previous studies on GABA in the stomach suggest GABAergic neuron is involved in acid secretion, but the effects of taurine are poor understood. Methods The effects of taurine on acid secretion, signal transduction, and localization of taurinergic neurons were determined in the rat stomach using everted whole stomach, RIA kit and immunohistochemical methods.

    Background Taurine has chemical structure similar to an inhibitory neurotransmitter, γ-aminobutyric acid (GABA). Previous studies on GABA in the stomach suggest GABAergic neuron is involved in acid secretion, but the effects of taurine are poor understood. Methods The effects of taurine on acid secretion, signal transduction, and localization of taurinergic neurons were determined in the rat stomach using everted whole stomach, RIA kit and immunohistochemical methods. Results We used antibodies against taurine-synthesizing enzyme, cysteine sulfuric acid decarboxylase (CSAD), and taurine. CSAD- and taurine-positive cells were found in the muscle and mucosal layers. Distributions of CSAD- and taurine-positive cells in both mucosal and muscle layers were heterogeneous in the stomach.

    Helicobacter pylori's ability to respond to environmental cues in the stomach is integral to its survival. By directly visualizing H. pylori swimming behavior when encountering a microscopic gradient consisting of the repellent acid and attractant urea, we found that H. pylori is able to simultaneously detect both signals, and its response depends on the magnitudes of the individual signals. By testing for the bacteria's response to a pure acid gradient, we discovered that the chemoreceptors TlpA and TlpD are each independent acid sensors. They enable H. pylori to respond to and escape from increases in hydrogen ion concentration near 100 nanomolar. TlpD also mediates attraction to basic pH, a response dampened by another chemoreceptor TlpB. H. pylori mutants lacking both TlpA and TlpD (ΔtlpAD) are unable to sense acid and are defective in establishing colonization in the murine stomach. However, blocking acid production in the stomach with omeprazole rescues ΔtlpAD's colonization defect. We used 3D confocal microscopy to determine how acid blockade affects the distribution of H. pylori in the stomach. We found that stomach acid controls not only the overall bacterial density, but also the microscopic distribution of bacteria that colonize the epithelium deep in the gastric glands. In omeprazole treated animals, bacterial abundance is increased in the antral glands, and gland colonization range is extended to the corpus. Our findings indicate that H. pylori has evolved at least two independent receptors capable of detecting acid gradients, allowing not only survival in the stomach, but also controlling the interaction of the bacteria with the epithelium.

  17. Fish stomach contents in benthic macroinvertebrate assemblage assessments

    TH. Tupinambás

    Full Text Available The choice of sampling gears to assess benthic macroinvertebrate communities depends on environmental characteristics, study objectives, and cost effectiveness. Because of the high foraging capacity and diverse habitats and behaviors of benthophagous fishes, their stomach contents may offer a useful sampling tool in studies of benthic macroinvertebrates, especially in large, deep, fast rivers that are difficult to sample with traditional sediment sampling gear. Our objective was to compare the benthic macroinvertebrate communities sampled from sediments with those sampled from fish stomachs. We collected benthic macroinvertebrates and fish from three different habitat types (backwater, beach, riffle in the wet season, drying season, and dry season along a single reach of the Grande River (Paraná River Basin, southeast Brazil. We sampled sediments through use of a Petersen dredge (total of 216 grabs and used gill nets to sample fish (total of 36 samples. We analyzed the stomach contents of three commonly occurring benthophagous fish species (Eigenmannia virescens, Iheringichthys labrosus, Leporinus amblyrhynchus. Chironomids dominated in both sampling methods. Macroinvertebrate taxonomic composition and abundances from fish stomachs differed from those from sediment samples, but less so from riffles than from backwater and beach habitats. Macroinvertebrate taxa from E. virescens stomachs were more strongly correlated with sediment samples from all three habitats than were those from the other two species. The species accumulation curves and higher mean dispersion values, compared with with sediment samples suggest that E. virescens is more efficient than sediment samples and the other fish studied at collecting benthic taxa. We conclude that by analyzing the stomach contents of benthophagous fishes it is possible to assess important characteristics of benthic communities (dispersion, taxonomic composition and diversity. This is especially true

    Stomach and colorectal cancers are common cancers and leading causes of cancer deaths. Because the alimentary tract can interact directly with dietary components, stomach and colorectal cancer may be closely related to dietary intake. We systematically searched published literature written in English via PubMed by searching for terms related to stomach and colorectal cancer risk and dietary flavonoids up to June 30, 2012. Twenty-three studies out of 209 identified articles were finally selected for the analysis. Log point effect estimates and the corresponding standard errors were calculated using covariate-adjusted point effect estimates and 95%CIs from the selected studies. Total dietary flavonoid intake was not associated with a reduced risk of colorectal or stomach cancer [odds ratio (OR) (95%CI) = 1.00 (0.90-1.11) and 1.07 (0.70-1.61), respectively]. Among flavonoid subclasses, the intake of flavonols, flavan-3-ols, anthocyanidins, and proanthocyanidins showed a significant inverse association with colorectal cancer risk [OR (95%CI) = 0.71 (0.63-0.81), 0.88 (0.79-0.97), 0.68 (0.56-0.82), and 0.72 (0.61-0.85), respectively]. A significant association was found only between flavonols and stomach cancer risk based on a limited number of selected studies [OR (95%CI) = 0.68 (0.46-0.99)]. In the summary estimates from case-control studies, all flavonoid subclasses except flavones and flavanones were inversely associated with colorectal cancer risk, whereas neither total flavonoids nor any subclasses of flavonoids were associated with colorectal cancer risk in the summary estimates based on the cohort studies. The significant association between flavonoid subclasses and cancer risk might be closely related to bias derived from the case-control design. There was no clear evidence that dietary flavonoids are associated with reduced risk of stomach and colorectal cancer.

  19. Stomach emptiness in fishes: Sources of variation and study design implications

    2011-01-01

    This study summarizes fish stomach content data from 369,000 fish from 402 species in 1,096 collections and reports on the percentage of individuals with empty stomachs. The mean percentage of individuals with empty stomachs among all species, locations, habitats, seasons, regions, and collection methods was 26.4%. Mean percentage of individuals with empty stomachs varied significantly among fish collection gear types, taxonomic orders, trophic groups, feeding behaviors, and habitats, and with species length at maturity. Most of the variation in percentage of individuals with empty stomachs was explained by species length at maturity, fish collection gear type, and two autecological factors: trophic group (piscivore percentage of individuals with empty stomachs > non-piscivore percentage of individuals with empty stomachs) and feeding habitat (water column feeder percentage of individuals with empty stomachs > benthic feeder percentage of individuals with empty stomachs). After accounting for variation with fish length, the percentage of individuals with empty stomachs did not vary with the stomach removal collection method (dissection vs. gastric lavage), feeding time (diurnal or nocturnal), or time of collection (day or night). The percentage of individuals with empty stomachs was similar between fresh and saltwater fish, but differed within finer habitat classifications and appeared to follow a general prey availability or productivity gradient: percentage of individuals with empty stomachs of open ocean collections > estuary collections, lentic > lotic, and pelagic > littoral. Gear type (active or passive) was the most influential factor affecting the occurrence of empty stomachs that can be readily controlled by researchers.

    The Kafue lechwe is endemic to the Kafue Flats area of Zambia. It is semi-aquatic in habit, feeding upon grasses above and below the waterline. The volume of the lechwe rumen is 17 L in the male and 14 L in the female. It has strong and definite pillars. The interior of the rumen is papillated except in the roof area and on the pillars. The omasum has more than 70 laminae which are papillated on the reticular end. The anatomy of the lechwe stomach is similar to the stomachs of other water dependent grazers such as Bohor Reedbuck, Waterbuck, Uganda Kob and Puku.

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

    To explore the genetic evolutionary distance between plants by using karyotype parameters identification of medicinal plants. The cluster analysis of karyotype resemblance-near coefficient and evolutionary distance was used for 6 Bupleurum species. The results showed that there were the biggest karyotype resemblance-near coefficient (0.9920) and the smallest evolutionary distance (D(e) = 0.0080) between B. scorzonerifolium and B. chinense, indicating the closest relationship, and the minimum karyotype resemblance-near coefficient (0.4794) and the maximum evolutionary distance (D(e) = 0.7352) between B. smityii and B. falcatum, indicating the most distant relationship. Karyotype was an important parameter for identification of medicinal plants because karyotype was stabilized for species. The genetic distance between in 6 species of Bupleurum species was obtained by karyotype clustering analysis of karyotype resemblance-near coefficient. There was the bigger evolutionary distance between the species which had different chromosome number.

    Stomach cancer was a leading cause of cancer-related deaths early in the 20th century and has steadily declined over the last century in the United States. Although incidence and death rates are now low, stomach cancer remains an important cause of morbidity and mortality in black, Asian and Pacific Islander, and American Indian/Alaska Native populations. Data from the CONCORD-2 study were used to analyze stomach cancer survival among males and females aged 15 to 99 years who were diagnosed in 37 states covering 80% of the US population. Survival analyses were corrected for background mortality using state-specific and race-specific (white and black) life tables and age-standardized using the International Cancer Survival Standard weights. Net survival is presented up to 5 years after diagnosis by race (all, black, and white) for 2001 through 2003 and 2004 through 2009 to account for changes in collecting Surveillance, Epidemiology, and End Results Summary Stage 2000 data from 2004. Almost one-third of stomach cancers were diagnosed at a distant stage among both whites and blacks. Age-standardized 5-year net survival increased between 2001 to 2003 and 2004 to 2009 (26.1% and 29%, respectively), and no differences were observed by race. The 1-year, 3-year, and 5-year survival estimates were 53.1%, 33.8%, and 29%, respectively. Survival improved in most states. Survival by stage was 64% (local), 28.2% (regional), and 5.3% (distant). The current results indicate high fatality for stomach cancer, especially soon after diagnosis. Although improvements in stomach cancer survival were observed, survival remained relatively low for both blacks and whites. Primary prevention through the control of well-established risk factors would be expected to have the greatest impact on further reducing deaths from stomach cancer. Cancer 2017;123:4994-5013.

    Pancreatic-type acinar cell carcinoma (ACC) in the stomach is extraordinarily rare. We pathologically examined two cases with multiple primary carcinomas, including gastric tumors. Gastric cancer specimens were examined by immunostaining and electron microscopy. Both cases had cancer cells with acinar patterns, resembling pancreatic ACC. The cancer cells in the first case were positive for exocrine markers, including chymotrypsin, lipase and alpha-1 antichymotrypsin (ACT), as well as neuroendocrine markers, including chromogranin A and synaptophysin. The cancer cells in the second case were positive for chymotrypsin and alpha-1 ACT, while being slightly positive for chromogranin A and synaptophysin. Ultrastructurally, cancer cells contained zymogen granules in both cases. The final diagnosis was pancreatic mixed acinar-neuroendocrine carcinoma and pure pancreatic ACC, respectively. We confirmed two cases with gastric pancreatic-type ACC included in multiple primary carcinomas. This type of double cancer has not been reported previously.

    In a basic study of intraoperative radiation on the stomach, adult dogs were laparotomized, and radiated on the stomach and gastroduodenal anastomosed part with an electron beam to 1,000 - 4,000 rads to observed its effects on hematologic and histologic findings. 1) No leukopenia occurred with the radiation, but secondary effects such as anemia and hypoproteinemia were noted. 2) On the gastric wall, the mucosa was most severely effected by the radiation, presenting such changes as erosion, atrophy, disappearance of glandular tissue, and fibrosis with the lapse of time. 3) The radiation on the stomach to 3,000 rads was followed by ulceration in one month, by the start of repair of the ulceration in three months, and by its healing in eight months. Histologic examination disclosed no evident damages to the blood vessels by the radiation. 4) Delayed healing of the anastomosed part was noted as an effect of the radiation on this part. 5) The findings in this experiment appear to suggest that the single tolerable dose of electron beam radiation on the stomach and the gastroduodenal anastomosed part should be 3,000 rads.

    The growing prevalence of endoscopic surgery in recent years has led to the minimization of postoperative scarring. However, this procedure does not allow for the regeneration of the resected digestive tract, which compromises the postoperative maintenance of digestive function. In this preliminary study, we developed an artificial gastric wall (AGW) using bioabsorbable polymer (BAP), and evaluated the ability of this BAP patch to repair and regenerate a widely defective gastric wall in an animal model. Pigs were laparotomized under general anesthesia. An 8 × 8-cm, round portion of the anterior gastric wall was excised and replaced by an AGW. The AGW was composed of a copolymer comprising 50% lactic acid and 50% caprolactone. The animals were relaparotomized 4, 8, or 12 weeks after implantation, after which they underwent resection of the entire stomach for gross and histologic evaluation of the graft sites. All recipient pigs survived until killing. By 4-8 weeks, the graft site revealed progressively fewer mucosal defect after each day. Moreover, the grafted area was indistinguishable from the native stomach 12 weeks after AGW implantation. The structures of the regenerated mucous membrane and muscle layers were identical to those of the native stomach. Furthermore, proton pumps were found in the regenerated tissue. The BAP sheets helped to restore extensive gastric defects without causing any deformation. The use of BAP sheets may become a new therapeutic method that prevents alterations of gastric volume after extensive gastrectomy for stomach cancer and other diseases. Copyright © 2015 Elsevier Inc.

    Fetuses with concomitant duodenal atresia (DA) and esophageal atresia (EA) might develop in utero gastric rupture as well as neonatal respiratory complication due to dilated stomach and duodenum. Our patient with the typical "double bubble" appearance was highly suspected to have DA in the second trimester. Follow-up examinations revealed a massively dilated stomach and duodenum with a dilated distal esophagus, indicating concomitant DA and EA. With advancing pregnancy, the fetal abdomen progressively increased in size by retention of fluid in the closed loop of DA and EA. To avoid gastric perforation, prenatal stomach paracentesis using an ultrasound-guided needle was performed three times until delivery. A male neonate born at 37 weeks gestation showed no respiratory complication. Perinatal clinical features and operative findings revealed combined DA and EA (gross type A). He was successfully managed with duodenoduodenostomy, followed by esophago-esophagostomy. On fetal sonography, the marked "double bubble" appearance and the cystic structure presenting peristalsis-like movement above the diaphragm were indicative of concomitant DA and EA. Fetal stomach paracentesis could contribute to the improvement of perinatal outcomes in fetuses with this pathological condition.

    The local resection of the stomach is an ideal method for preventing postoperative symptoms. There are various procedures for performing local resection, such as the laparoscopic lesion lifting method, non-touch lesion lifting method, endoscopic full-thickness resection, and laparoscopic endoscopic cooperative surgery. After the invention and widespread use of endoscopic submucosal dissection, local resection has become outdated as a curative surgical technique for gastric cancer. Nevertheless, local resection of the stomach in the treatment of gastric cancer in now expected to make a comeback with the clinical use of sentinel node navigation surgery. However, there are many issues associated with local resection for gastric cancer, other than the normal indications. These include gastric deformation, functional impairment, ensuring a safe surgical margin, the possibility of inducing peritoneal dissemination, and the associated increase in the risk of metachronous gastric cancer. In view of these issues, there is a tendency to regard local resection as an investigative treatment, to be applied only in carefully selected cases. The ideal model for local resection of the stomach for gastric cancer would be a combination of endoscopic full-thickness resection of the stomach using an ESD device and hand sutured closure using a laparoscope or a surgical robot, for achieving both oncological safety and preserved functions.

    2015-06-01

    Epidemiological studies on aspirin and stomach cancer have been inconclusive. The purpose of our study was to investigate the association between aspirin and stomach cancer in China. A 1:2 matched case-control study was conducted in four large medical centers. A self-designed questionnaire was used to collect information. Unconditional logistic regression was used to compute crude and adjusted odds ratios (ORs) with 95% confidence intervals (CIs). Our study indicated that risk of stomach cancer was greatly reduced for regular aspirin user (OR = 0.62; 95% CI 0.42-0.80). Specifically, dosage and tablet-years of use were associated with lower risk (OR = 0.54; 95% CI 0.29-0.84 for ≥7 tabs/week; OR = 0.47; 95% CI 0.32-0.81 for ≥10 tablet years, respectively). Furthermore, the finding was strengthened by stratified studies of gender, smoking status, body mass index (BMI) and helicobacter pylori. Our study confirmed that regular aspirin use is a protective factor to stomach cancer. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Mass screening of stomach cancer is one of the largest screening systems in Japan. In the previous paper, we have described the benefit-risk analysis in terms of life-saving due to early detection of stomach cancer and loss of life due to late induction of cancer by radiation. In this paper, we report the genetic effect of x-ray diagnosis used in the mass screening and cost-effectiveness for the screening program. The former is calculated by the product of genetically significant dose and rate of induction for genetic effects. Since the genetically significant dose in woman is about 10 times larger than that in man, the genetic risk is greater in woman accordingly. It is also found that the genetic risk over 40 years old is only 3% of the risk in the whole population and that it is almost neglected if the screening is performed only over age of 40. Cost of the screening is estimated to be yen 3,000/person which includes that of photofluorography and a part of other detailed examinations. Since total population screened is about 4 million in 1975, the total amount of cost is 1.2 x 10 10 yen/year. Cost per person-year is mainly dependent upon the age of the person: for one person-year in man or woman of 15 - 19 years old, the cost is about 20 million yen, but it is about 150,000 yen for man of 70 - 74 years old. These information is useful in the decision on the mass screening policy for stomach cancer in Japan. (auth.)

    Although the incidence of stomach cancer has been declining, it remains the second leading cause of cancer death worldwide. Potential protective effects of allium vegetables against cancer have been reported by a few epidemiologic studies in Chinese populations, but the sample sizes of these studies were relatively small. We examined the associations between allium vegetable consumption and stomach cancer in a large population-based case-control study in Shanghai (750 cases and 750 age- and gender-matched controls) and Qingdao (128 cases and 128 age- and gender-matched controls). Epidemiological data were collected by a standard questionnaire, and odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using conditional logistic regression in SAS. After adjusting for matching variables, education, body mass index, pack-years of smoking, alcohol drinking, salt intake, and fruit and vegetable intake, inverse relationships with dose response pattern were observed between frequency of onion intake and stomach cancer in Qingdao (P for trend=0.02) and Shanghai (P for trend=0.04) populations. In Shanghai, negative dose-response relationships were observed between monthly intake of onions (P=0.03), monthly intake of garlic stalks (P=0.04) and distal cancer (but not with cardia cancer). Negative association was also noted between intake of garlic stalks (often vs. never) and risk of stomach cancer in Qingdao (OR=0.30; 95% CI: 0.12–0.77). Our results confirm the protective effect of allium vegetables (especially garlic and onions) against stomach cancer. PMID:16236005

    The aim of this study was to identify sonographic (US) findings that can assist in prenatal diagnosis of stomach-down left congenital diaphragmatic hernia (CDH), specifically related to positioning of the abdominal contents including the stomach, bladder, and gallbladder. All US examinations with a postnatally confirmed diagnosis of stomach-down left CDH over a 13-year period were retrospectively reviewed for abnormal position of the abdominal contents, including whether the fetal stomach was in contact with the urinary bladder. Normal fetuses that underwent comprehensive US surveys were similarly evaluated for comparison in a 2:1 ratio. Twenty-two fetuses with stomach-down left CDH were identified in a cohort of 278 fetuses with left CDH. In 15/22 (68.2%) cases of stomach-down left CDH, the bladder and stomach walls were in contact. Contact of the fetal gallbladder with the fetal bladder wall was also observed and was present even more commonly (17/22 cases [77.3%]). There was no case of either the stomach or gallbladder in contact with the bladder wall in the normal fetal cohort (n = 44). Recognition of the fetal stomach and/or gallbladder in contact with the bladder wall can help in the detection of stomach-down left CDH. © 2016 Wiley Periodicals, Inc.

  19. Role of present-day roentgenology in the diagnosis of peptic ulcer with its site in the stomach

    International Nuclear Information System (INIS)

    Portnoj, L.M.

    1996-01-01

    By using the goaloriented X-ray study along with endoscopy in over 600 patients with peptic ulcer with its site in the stomach (PUSS) both for its primary diagnosis and during its treatment and in various posttreatment periods (from 3 to 6 years), the author supposes that X-ray due to its characteristic three-dimensional image of the stomach will provide comprehensive syndrome information as to its benign ulcerations. The author failed to observe signs of their malignancy in none of more than 600 long-term follow-ups, which made him state that appropriate correctives approaches to this problem should be applied. Active use of X-ray techniques to verify the efficiency of the therapy performed eliminates the bulk of problems in the diagnosis of benign and malignant gastric ulcerations, especially those associated with the differentiation of a postulcerous scar and early gastric cancer. 73 refs., 7 figs

    Full Text Available Há cinqüenta anos o câncer de estômago vem perdendo a importância em termos de morbi-mortalidade em países considerados de primeiro mundo. Isso não ocorre no Brasil. Os principais fatores de risco evidenciados a partir de estudos epidemiológicos em várias populações do mundo e associados a essa neoplasia são alguns padrões de dieta. Com a descoberta do papel carcinogênico das nitrosaminas e do potencial anti-oxidante da vitamina C, algumas das associações entre câncer gástrico e padrões de dieta passaram a ser parcialmente entendidas. Com a descrição da Helicobacter pylori em 1983 e as evidências da relação dessa bactéria com certos processos patológicos do estômago, alguns precursores do câncer gástrico, novos elementos foram agregados ao processo fisiopatológico dessa entidade. O conhecimento hoje adquirido sobre a fisiopatologia do câncer gástrico, mesmo que parcial, fornece perspectivas estimulantes para prevenção e diagnóstico precoce.For the last fifty years, stomach cancer has become less important in terms of morbidity and mortality in developed countries, but the same pattern has not occurred in Brazil. The main risk factors for this neoplasm are certain diet patterns that became evident through epidemiological studies in various population groups. After the carcinogenic effects of nitrosamines and the anti-oxidant activity of vitamin C were discovered, some of the associations between stomach cancer and diet were partially understood. After the description of Helicobacter pylori in 1983 and the evidence of the relationship between this bacteria and certain stomach diseases, new elements were added to the knowledge about the development of this neoplasm. Current knowledge, albeit incomplete, provides interesting prospects for the prevention and early diagnosis of stomach cancer.

    Uterine tumor resembling ovarian sex-cord tumor is a very rare uterine neoplasm that was first described by Clement and Scully in 1976. Since then, approximately 70 cases have been reported. However, these case reports have mainly described and discussed the pathologic and clinical features, and few radiologic findings have been presented. We experienced a case of a uterine tumor resembling ovarian sex-cord tumor, which was considered a uterine leiomyoma or leiomyosarcoma upon initial impression at preoperative evaluation including transvaginal ultrasonography and pelvic magnetic resonance imaging. Its diagnosis was pathologically confirmed after total abdominal hysterectomy.

    On 20 May 1961 an immature female tiger shark (Galeocerdo cuvier), 2.3 meters in length and weighing 52 kg, was caught in the Gulf of Mexico several miles offshore from Sarasota, Florida, by personnel of the Cape Haze Marine Laboratory. The contents of its stomach included a leg and some feathers of a land bird. The leg was sent to the Bird and Mammal Laboratories, Bureau of Sport Fisheries and Wildlife, Washington, D.C., where it was identified by Mrs. R. C. Laybourne as that of a Yellow-billed Cuckoo (Coccyzus americanus). In addition to this bird, the stomach contained a blue crab, several sea catfishes (Galeichthys felis), and part of a black nose shark (Carcharhinus acronatus).

    Metastatic disease from pancreatic carcinoma involving the stomach is an unusual event, and the pattern of spread in the form of linitis plastica, to our knowledge, has not been reported previously. Local recurrence after curative resection for pancreatic cancer is the most common pattern of disease. We report a case of metastatic pancreatic adenocarcinoma presenting as linitis plastica of the stomach 4 years after curative resection. A 52-year-old man presented with epigastric pain and melaena 4 years after undergoing a Whipple's procedure for a poorly-differentiated pancreatic adenocarcinoma, stage IB; T2N0M0. CT imaging of the abdomen revealed thickening of the gastric wall, and subsequent oesophagogastroduodenoscopy (OGD) revealed diffuse friable erythaematous tissue. The biopsy specimen obtained during the OGD revealed a poorly differentiated adenocarcinoma, with similar appearance to the prior specimen obtained from the pancreas. 2016 BMJ Publishing Group Ltd.

    Objective: To estimate the incidence and mortality of stomach cancer in China based on the cancer registration data in 2013, collected by the National Central Cancer Registry (NCCR). Methods: There were 347 cancer registries that submitted stomach cancer incidence and deaths occurred in 2013 to NCCR. After evaluating the data quality, 255 registries' data were accepted for analysis and stratified by areas (urban/rural), sex, and age group. Combined with data on national population in 2013, the nationwide incidence and mortality of stomach cancer were estimated. Chinese population census in 2000 and Segi's population were used for age-standardized incidence/mortality rates. Results: Qualified 255 cancer registries covered a total of 226 494 490 populations (111 595 772 in urban and 114 898 718 in rural areas). The percentage of cases morphologically verified and death certificate-only cases were 76.27% and 1.98%, respectively, and the mortality to incidence rate ratio was 0.72. It is estimated that there were 427 000 new cases for stomach cancer nationwide, with a crude incidence rate of 31.38 per 100 000 (42.85 per 100 000 in males, 19.33 per 100 000 in females). The age-standardized incidence rates by Chinese standard population (ASR China) and by world standard population (ASR world) were 21.40 per 100 000 and 21.32 per 100 000, respectively, with a cumulative incidence rate (0-74 age years old) of 2.66%. The crude and ASR China incidence rates of stomach cancer in urban areas were 27.80 per 100 000 and 18.48 per 100 000, respectively, whereas those were 35.54 per 100 000 and 24.93 per 100 000 in rural areas. It is estimated that there were 301 000 deaths for stomach cancer nationwide, with a crude mortality rate of 22.13 per 100 000 (29.85 per 100 000 in males, 14.03 per 100 000 in females). The ASR China and ASR world mortality rates were 14.68 per 100 000 and 14.54 per 100 000, respectively, with a cumulative mortality rate (0-74 years old) of 1.70%. The crude

    The causes, incidence of, and the time of occurrence of cancer of the stomach resected for benign diseases are analyzed. The outcomes of 384 operations for recurrent gastric cancer, including 174 radical ones, are presented. The highest resectability was noted in late recurrence and following Bilroth-II gastrectomy with long-loop forward colonic anastomosis. The late outcomes depend on the time of recurrence, its location in the remaining part of the stomach, and the presence of lymphogenic metastases. Experience of 16 extirpations of esophagojejunal anastomosis was used to show whether recurrent gastric cancer after gastrectomy with satisfactory immediate and long-term outcomes can be surgically treated. The fate of 292 patients with gastric cancer in whom tumor cells were detected along the line of resection is traced. Preventive resurgery in this group of patients is not unjustifiable as in 80.8% of them recurrence fails to occur at all or is followed by late metastases.

  1. Gelation of mucin: Protecting the stomach from autodigestion

    2011-03-01

    In this talk I will describe the molecular mechanisms involved in the remarkable ability of the mucus lining of the stomach for protecting the stomach from being digested by the acidic gastric juices that it secretes. These physical properties can be attributed to the presence of a high molecular weight glycoprotein found in mucus, called mucin. Rheology and other measurements show that gastric mucin forms a gel under acidic pH. A model of gelation based on the interplay of hydrophobic and electrostatic interactions will be discussed. Molecular Dynamics simulation studies of folding and aggregation of mucin domains provide further support for this model. The relevance of gelation to the motion of the ulcer causing bacterium H. pylori will be discussed.

    With the aid of hepatobiliary sequence scintigraphy (HBSS) a functional analysis was obtained form 30 patients, subsequent to gastric surgery - after Billroth II with entero-anastomosis - which showed a suprisingly high rate of reflux into the residual stomach, in 16 out of these 30 patients. The high-grade HBSS data with regard to the biliary reflux proportions after gastric surgery and the low-grade effectiveness of Braun's entero-anastomosis are clearly evidenced. (orig./MG) [de

    Although hematogenous metastasis of cancer to the gastrointestinal track is rare, it sometime has been reported in patients with malignant melanoma and breast cancer. However, it is extremely rare for lung cancer to metastasize to the stomach, not to mention solitary gastric metastasis. Herein, the authors report a case of a 69-year-old man who was initially diagnosed with lung cancer with synchronous primary gastric cancer which proved to be lung cancer with solitary gastric metastasis after the operation.

    Accumulating evidence has implicated Helicobacter pylori, an established cause of chronic gastritis and peptic ulcer, in the etiology of gastric cancer. Control of this infection would reduce the occurrence of chronic gastritis and peptic ulcer and might substantially lower the risk of stomach cancer as well. The public health impact of this infectious agent warrants efforts to identify preventive measures. This paper reviews the evidence linking H. pylori infection to gastric cancer and eval...

    In this article, the tensile properties of gastric wall were investigated by using biomechanical test and theoretical analysis. The samples of porcine stomach strips from smaller and greater curvature of the stomach were cut in longitudinal and circumferential direction, respectively. The loading-unloading, stress relaxation, strain creep, tensile fracture tests were performed at mucosa-submucosa, serosa-muscle and intact layer, respectively. Results showed that the biomechanical properties of the porcine stomach depended on the layers, orientations and locations of the gastric wall and presented typical viscoelastic, nonlinear and anisotropic mechanical properties. During loading-unloading test, the stress of serosa-muscle layer in the longitudinal direction was 15-20% more than that in the circumferential direction at 12% stretch ratio, while it could reach about 40% for the intact layer and 50% for the mucosa-submucosa layer. The results of stress relaxation and strain creep showed that the variation degree was obviously faster in the circumferential direction than that in the longitudinal direction, and the ultimate residual values were also different for the different layers, orientations and locations. In the process of fracture test, the serosa-muscle layer fractured firstly followed by the mucosa-submucosa layer when the intact layer was tested, the longitudinal strips firstly began to fracture and the required stress value was about twice as much as that in the circumferential strips. The anisotropy and heterogeneity of mechanical characterization of the porcine stomach were related to its complicated geometry, structure and functions. The results would help us to understand the biomechanics of soft organ tissue. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Osteoblast activating peptide (OBAP) was previously reported to be expressed in the rat stomach and to have a vital role in osteogenesis, but its distribution in rat stomach has not been determined. Thus, the aim of the present study was to identify the cell types expressing OBAP in the rat stomach. The stomachs of twelve 10-to-11-week-old male Jc1:SD rats were used. Samples were collected for immunohistochemistry, immunoelectron microscopy and dot blot assay. Immunohistochemical investigation revealed that OBAP was distributed mainly in parietal cells without any expression in chief cells, X/A-like cells or enterochromaffin-like cells. Moreover, OBAP-immunopositive cells were observed mainly in the upper and lower parts of the gastric gland. Significantly high optical density of immunopositive cells was observed in the upper and lower gastric gland regions. The dot blot assay confirmed that OBAP is secreted by parietal cells and that it is present in the gastric gland lumen. Immunoelectron microscopy demonstrated that OBAP was confined to the mitochondrial inner membrane within parietal cells and that the number of mitochondria in the upper and lower parts of the gastric epithelium was significantly larger than the number in the middle part of the gastric epithelium. Based on the results, it was concluded that OBAP is mainly produced by mitochondria of parietal cells in the upper and lower parts of the gastric epithelium. Moreover, the presence of OBAP in the gastric gland lumen suggests an exocrine mechanism of release. Copyright © 2015 Elsevier GmbH. All rights reserved.

    To investigate the clinical effect of residual stomach, duodenum, and continual jejunal interposition on the patients of gastric cancer after subtotal gastrectomy. Fifty-four patients with gastric cancer after subtotal gastrectomy were randomly divided into 2 groups: Group A (n = 26, receiving digestive tract reconstruction by manual end-to-side anastomosis of residual stomach and jejunum, end-to-side anastomosis of residual duodenum and jejunum, and side-to-side anastomosis of jejunum and jejunum, then the jejunum proximal to the stomach-jejunum anastomosis and the jejunum distal to the duodenum-jejunum anastomosis were ligated so as to form an integral continual jejunal interposition; and Group B (n = 28, receiving Bilroth digestive tract reconstruction. The operation time, body weight, prognosis nutrition index (PNI), and Visick score 3 and 6 months after the operation were observed. All patients recovered quickly and no complicating anastomosis leakage and obstruction was found. It took 53 +/- 9 minutes to finish the reconstruction in Group A, significantly shorter than that in Group B (57 +/- 6 minutes, t = -2.145, P = 0.037). The body weight and PNI of both groups decreased significantly 3 months after the operation in comparison with those before the operation (both P < 0.05). The body weight and PNI of Group A returned to the levels before operation. Although the body weight and PNI of Group B recovered to some extent 6 months after operation, they remained significantly lower than those before operation both P < 0.05). The Visick score 6 months after operation of Group A was superior to that of Group B (t = 2.1 P < 0.05). Residual stomach, duodenum, and continual jejunal interposition after subtotal gastrectomy helps overcome the difficulty in the procedure of digestive tract reconstruction and restore the physiological passage through duodenum, thus avoiding reflux and improving patients' quality of life.

    The evaluation of the characteristics of the fetal stomach should be part of every routine prenatal ultrasound after 11 weeks. A position that has not been previously described in the literature is the stomach in contact with the bladder. We describe 6 cases with the ultrasonographic finding of the stomach in contact with the bladder, all of them in fetuses with left-sided congenital diaphragmatic hernia. Even though the reasons for this striking position of the stomach are not clear, our series highlights the fact that the visualization of the stomach in contact with the bladder may be a specific sonographic marker of congenital diaphragmatic hernia. © 2015 S.

    We investigated the community structure of bacteria that populate the stomach of the Brumby, a breed of feral horses from the Australian outback. Using a 16S rRNA gene clone library, we identified 155 clones that were assigned to 26 OTUs based on a 99.0 % sequence identity cutoff. Two OTUs represented 73.5 % of clones, while 18 OTUs were each assigned only a single clone. Four major bacterial types were identified in the Brumby stomach: Lactobacillaceae, Streptococcaceae, Veillonellaceae and Pasteurellaceae. The first three groups, which represented 98.1 % of the Brumby stomach library clones, belonged to the bacterial phylum Firmicutes. We found that 49.7 % of clones were related to bacterial species previously identified in the equine hindgut, and that 44.5 % of clones were related to symbiotic bacterial species identified in the mouth or throat of either horses or other mammals. Our results indicated that the composition of mutualistic bacterial communities of feral horses was consistent with other studies on domestic horses. In addition to bacterial sequences, we also identified four plastid 16S rRNA gene sequences, which may help in further characterizing the type of vegetation consumed by Brumby horses in their natural environment.

    Although salient stimuli are known to modulate startle eye-blink responses, and one's own face is considered of particular salience, effects of facial self-resemblance on startle responsiveness have not been systematically investigated. For the present study, pictures from the FACES database (rated as neutral) were digitally morphed to resemble the participants' (N=37) faces to varying degrees (25-50-75%). Perceptually matched geometrical shapes served as a control condition. At SOAs of either 300ms or 3000ms after picture onset, startle responses were elicited by white noise (50ms, 105dB), and recorded at the orbicularis oculi via EMG. Prior to the experiment, self-reported mood was assessed by means of the PANAS. Relative to non-face stimuli, the presentation of faces reduced startle magnitude at short, but not long, lead intervals. Furthermore, for probes presented at a SOA of 300ms, a linear decrease in startle magnitude with higher levels of self-resemblance was observed, presumably reflecting higher salience of the self-face. The startle modulating effect of self-resembling faces during longer lead intervals was moderated by the participants' current mood: negative affect predicted stronger patterns of attenuation, which might be interpreted as an increase in self-focus resulting from more negative mood.

    With the rapid advancement of minimally invasive new technology, laparoscopic surgery and robotic surgery are now regarded as the main direction in surgical treatment for stomach cancers. Recent evidence has confirmed the safety and feasibility of laparoscopic surgery for early gastric cancer and advanced gastric cancer. However, gastrointestinal surgeons should pay more attention to complications after laparoscopic gastrectomy because of rich blood supply, complex tissue layers and lymph node metastasis. Common complications related to laparoscopic surgery are associated with laparoscopic instruments and operating, intra-abdominal bleeding, anastomotic leakage, anastomotic bleeding, pancreatic leakage, duodenal stump leakage, lymphatic leakage and so on. This article mainly focuses on the causes, prevention and treatment of the complications after laparoscopic gastrectomy.

    A study on the diagnosis of carcinoma of the stomach was carried out in 105 selected Korean cases of histologically proved carcinoma of the stomach, aimed to the position and value of roentgenography and gastroscopy. The results were summarized as follows: 1) In the diagnosis of 105 cases of Korean gastric carcinomas, a correct diagnosis was made by roentgenography in 79.1 percent and by gastroscopy in 86.7 percent of all cases. Roentgenography plus gastroscopy permitted a correct diagnosis in 92.3 percent of all cases. There is no significant difference statistically on the diagnostic accuracy between roentgenography and gastroscopy (by t-test, t=0.8572). 2) In the diagnosis of carcinoma of the stomach, with roentgenography the greatest diagnostic error occurred in primary ulcerative lesions and with gastroscopy in inadequate examinations which were resulted from mechanical failures. It occurred also in mixed type of infiltration and ulceration for the gross pathology and in lesions of gastric body and pyloric antrum as the site of the lesion. 3) In this series of 105 cases of Korean gastric carcinomas, two cases of early gastric carcinoma (type IIc +III) were correctly diagnosed by roentgenography and gastroscopy. 4) In this series, the most frequent type of gross pathology appeared to be Bormann tpe III, type of ulceration with spreading infiltration, which was 72.4 percent of all 105 cases and the site of the lesion revealed the highest frequently in the pylorus in 53.3 percent, but both of these had little significance in the determination of diagnostic accuracy of roentgenography and/or gastroscopy in gastric carcinomas. 5) The onset of symptoms, clinical manifestations, and physical findings were reviewed in all 105 cases of this series. The predominant symptoms were epigastric pain (75.2 percent), indigestion (73.3 percent) and weight lose (57.0 percent) in the order and the most frequent physical findings was epigastric tenderness (68.6 percent).

    Stomach cancer is the third most common cause of death worldwide, mainly affecting people with low socioeconomic status. In Brazil, we expect 20,390 new cases of stomach cancer in 2014, in both sexes, and according to the proportional distribution of the ten most prevalent types of cancer (except non-melanoma skin cancer) expected for 2014, this type of cancer was estimated to be the fourth most common in men and sixth in women. To investigate and analyse the clinical and epidemiological profile of deaths caused by stomach adenocarcinoma in patients enrolled in the National Cancer Institute, Brazil. Cross-sectional study, with samples which consisted of data from the medical records of deaths from stomach cancer, enrolled in the period from 1 February 2009 to 31 March 2012 and who had died as of 30 April 2012. The Epi Info ®, version 7. We included 264 cases, mostly male. The mean age was 61.7 years. They were smokers, drinkers, white, and married, with elementary education and an income of one minimum salary. They had advanced stage disease (E IV), with symptoms characteristic of this phase, and the majority died within six months. The findings are similar to other studies. The advanced stage of the disease at the time of admission of the patients reflects the difficulty for users of the Unified Health System to access early diagnosis, demonstrating the need for efforts to identify groups and risk factors for the development of gastric cancer. Training of health professionals will facilitate planning and implementation of programmes for the prevention and control of disease, considering socioeconomic conditions, as seen in the sample, which is common among most users.

    Full Text Available On the base of our own observations and literature data it was determined that the distinctive pathologic features of MALT-lymphoma of the stomach are the presence of a dense diffuse lymphocytic infiltrate of centrocyte-like tumor cells of marginal zone (small cells resembling centrocytes with distinct bright rim of cytoplasm, with small nuclei of irregular shape, sometimes – split, containing coarse chromatin and indistinct nucleoli in the lamina propria between the reactive lymph follicles and glands of the mucous membrane, monocytoid B-lymphocytes characterized by clear cell borders, broad light cytoplasm and bean-like nucleus, plasma cells, which may contain Dutcher bodies – intranuclear inclusions of immunoglobulins; single large centroblast-like or immunoblast-like cells having round-oval or slightly irregular in shape nuclei with 1-3 nucleoli, or vesicular-like round in shape nuclei with compact, centrally located nucleolus; small lymphocytes. Infiltration looks as tumorcell layers or, more rarely, fuzzy nodular cellular formations. An important diagnostic criterion is the presence of "lymphoepithelial lesions" zones of glands due to infiltration by 3 or more centrocyte-like tumor cell aggregates with glands’ basement membranes destruction. In the damaged glands epithelium edema and eosinophilia are marked, but if extensive infiltration is present among the lymphoid infiltrate there are only clusters of degenerated cells at the site of destroyed epithelium. Low-grade MALT-lymphoma is characterized by the absence of distinct macroscopic changes and the prevalence of "mature" tumor cells over the blasts in histological picture. MALT-lymphoma with signs of transformation into high-grade lymphoma is characterized macroscopically by distinct exophytic component, hyperplasia of folds with ulcerous defects up to 1-2 cm in diameter. Histologic picture displays a significant amount of blast cells – both in the infiltrate and in the areas

    Spontaneous esophageal perforation, or Boerhaave's syndrome, is a life-threating condition which usually requires emergent surgery. An upside down stomach is defined as a gastric volvulus in a huge supradiaphragmatic sac. In general, this condition can result in ischemia and perforation of the stomach. This is the first report of a patient with Boerhaave's syndrome and an upside down stomach. A 79-year-old woman presented with sudden epigastric pain following hematemesis. Evaluation of the patient showed both an esophageal perforation and an upside down stomach. Surgical drainage and irrigation of the mediastinum and pleural cavities were undertaken emergently. Due to the concurrent gastric volvulus, a gastrostomy was placed to fix and decompress the stomach. The patient had an uneventful hospital course and was discharged. Boerhaave's syndrome is a rare but severe complication caused by excessive vomiting, due to a sudden elevation in intraluminal esophageal pressure resulting in esophageal perforation. Acute gastric volvulus can result in ischemia and perforation of the stomach, but has not previously been reported with esophageal perforation. The most likely mechanism associating an upside down stomach with Boerhaave's syndrome is acute gastric outlet obstruction resulting in vomiting, and subsequent esophageal perforation. Perforation of the esophagus as well as perforation of the stomach must be considered in patients with an upside down stomach although both upside down stomach and Boerhaave's syndrome are rare clinical entities.

    To provide a theoretical basis for the clinical care of patients with late stomach cancer, we investigated the life quality and analysed its related factor in the patients with late stomach cancer. Due to the lack of effective screening methods, stomach cancer usually has been in the advanced stage when patients are diagnosed. However, the treatment for late stomach cancer is a tough problem in today's medicine. Chemotherapy or radiotherapy brings patients physiological and psychological distress and heavy financial burden, affecting patients' therapeutic effects, prognosis and life quality. The patients with late stomach cancer were included, and then, questionnaires about the life quality were completed. Questionnaires including European Organisation for Research on Treatment of Cancer Quality of Life Questionnaire-Core 30, Social Support Rating Scale, Medical Coping Modes Questionnaire and Self-rating Anxiety Scale were completed by 173 patients with late stomach cancer who received treatment in our hospital between May 2010 and May 2011. Correlation analyses were performed. The overall score of the life quality of the patients with late stomach cancer was only 29·54 ± 12·21. The social support, medical coping modes, anxiety and patients' clinical data (except radiotherapy) markedly affected the overall life quality of the patients with late stomach cancer (p stomach cancer is poor and is associated with many factors.

    2005-01-01

    Purpose: Involved-field radiation therapy of the stomach is often used in the curative treatment of gastric lymphoma. Yet, the optimal technique to irradiate the stomach with minimal morbidity has not been well established. This study was designed to evaluate treatment planning alternatives for stomach irradiation, including intensity-modulated radiation therapy (IMRT), to determine which approach resulted in improved dose distribution and to identify patient-specific anatomic factors that might influence a treatment planning choice. Methods and Materials: Fifteen patients with lymphoma of the stomach (14 mucosa-associated lymphoid tissue lymphomas and 1 diffuse large B-cell lymphoma) were categorized into 3 types, depending on the geometric relationship between the planning target volume (PTV) and kidneys. AP/PA and 3D conformal radiation therapy (3DCRT) plans were generated for each patient. IMRT was planned for 4 patients with challenging geometric relationship between the PTV and the kidneys to determine whether it was advantageous to use IMRT. Results: For type I patients (no overlap between PTV and kidneys), there was essentially no benefit from using 3DCRT over AP/PA. However, for patients with PTVs in close proximity to the kidneys (type II) or with high degree of overlap (type III), the 4-field 3DCRT plans were superior, reducing the kidney V 15Gy by approximately 90% for type II and 50% for type III patients. For type III, the use of a 3DCRT plan rather than an AP/PA plan decreased the V 15Gy by approximately 65% for the right kidney and 45% for the left kidney. In the selected cases, IMRT led to a further decrease in left kidney dose as well as in mean liver dose. Conclusions: The geometric relationship between the target and kidneys has a significant impact on the selection of the optimum beam arrangement. Using 4-field 3DCRT markedly decreases the kidney dose. The addition of IMRT led to further incremental improvements in the left kidney and liver

    Endoscopic pertubation of oesophagogustric neoplasms is an established method of palliative treatment. The dislocated plastic prosthesis may be removed with difficulties from the stomach endoscopically. A simple technique for endoscopic removal of the prosthesis is described. The tube can be precisely centred within the oesophageal lumen by use of an intestinal decompression tube and additional guidance by the endoscopic retraction forceps. Thus gross damge of the exophytic tumor tissue with bleeding or perforation sequelae can be avoided. Injury to the patient does not exceed that caused by an ordinary gastroscopy.

    We report a case of facultative intestinal myiasis due to larvae of the drone fly Eristalis tenax, also named the rat-tailed maggots. The development of larvae in the lower bowel was responsible for non-specific gastrointestinal symptoms that resembled ulcerative proctitis. The diagnosis was established upon the observation of four spontaneously excreted mobile larvae. The definite identification of the E. tenax species was made possible by scanning electron microscopy. The clinical outcome was satisfactory.

    Full Text Available Sex differences in reaction to a romantic partner's infidelity are well documented and are hypothesized to be attributable to sex-specific jealousy mechanisms which are utilized to solve adaptive problems associated with risk of extra-pair copulation. Males, because of the risk of cuckoldry become more upset by sexual infidelity, while females, because of loss of resources and biparental investment tend to become more distressed by emotional infidelity. However, the degree to which these sex-specific reactions to jealousy interact with cues to kin are completely unknown. Here we investigated the interaction of facial resemblance with decisions about sex-specific jealousy scenarios. Fifty nine volunteers were asked to imagine that two different people (represented by facial composites informed them about their romantic partner's sexual or emotional infidelity. Consistent with previous research, males ranked sexual infidelity scenarios as most upsetting and females ranked emotional infidelity scenarios most upsetting. However, when information about the infidelity was provided by a face that resembled the subject, sex-specific reactions to jealousy were exaggerated. This finding highlights the use of facial resemblance as a putative self-referent phenotypic matching cue that impacts trusting behavior in sexual contexts.

    Red-meat lipid peroxidation in the stomach results in postprandial oxidative stress (POS) which is characterized by the generation of a variety of reactive cytotoxic aldehydes including malondialdehyde (MDA). MDA is absorbed in the blood system reacts with cell proteins to form adducts resulting in advanced lipid peroxidation end products (ALEs), producing dysfunctional proteins and cellular responses. The pathological consequences of ALEs tissue damage include inflammation and increased risk for many chronic diseases that are associated with a Western-type diet. In earlier studies we used the simulated gastric fluid (SGF) condition to show that the in vitro generation of MDA from red meat closely resembles that in human blood after consumption the same amount of meat. In vivo and in vitro MDA generations were similarly suppressed by polyphenol-rich beverages (red wine and coffee) consumed with the meal. The present study uses the in vitro SGF to assess the capacity of more than 50 foods of plant origin to suppress red meat peroxidation and formation of MDA. The results were calculated as reducing POS index (rPOSI) which represents the capacity in percent of 100g of the food used to inhibit lipid peroxidation of 200g red-meat a POSI enhancer (ePOSI). The index permitted to extrapolate the need of rPOSI from a food alone or in ensemble such Greek salad, to neutralize an ePOSI in stomach medium, (ePOS-rPOSI=0). The correlation between the rPOSI and polyphenols in the tested foods was R 2 =0.75. The Index was validated by comparison of the predicted rPOSI for a portion of Greek salad or red-wine to real inhibition of POS enhancers. The POS Index permit to better balancing nutrition for human health. Copyright © 2017. Published by Elsevier B.V.

    Puberty is an important developmental stage wherein hormonal shifts mediate the physical and physiological changes that lead to menarche, but until now, the bacterial composition of vaginal microbiota during this period has been poorly characterized. We performed a prospective longitudinal study of perimenarcheal girls to gain insight into the timing and sequence of changes that occur in the vaginal and vulvar microbiota during puberty. The study enrolled 31 healthy, premenarcheal girls between the ages of 10 and 12 years and collected vaginal and vulvar swabs quarterly for up to 3 years. Bacterial composition was characterized by Roche 454 pyrosequencing and classification of regions V1 to V3 of 16S rRNA genes. Contrary to expectations, lactic acid bacteria, primarily Lactobacillus spp., were dominant in the microbiota of most girls well before the onset of menarche in the early to middle stages of puberty. Gardnerella vaginalis was detected at appreciable levels in approximately one-third of subjects, a notable finding considering that this organism is commonly associated with bacterial vaginosis in adults. Vulvar microbiota closely resembled vaginal microbiota but often exhibited additional taxa typically associated with skin microbiota. Our findings suggest that the vaginal microbiota of girls begin to resemble those of adults well before the onset of menarche. This study addresses longitudinal changes in vaginal and vulvar microbial communities prior to and immediately following menarche. The research is significant because microbial ecology of the vagina is an integral aspect of health, including resistance to infections. The physiologic changes of puberty and initiation of cyclic menstruation are likely to have profound effects on vaginal microbiota, but almost nothing is known about changes that normally occur during this time. Our understanding has been especially hampered by the lack of thorough characterization of microbial communities using techniques

    Cholecystography with 99m Tc-EHIDA was performed to assess the preprandial empty function of gallbladder and then solid meal labelled with 99m Tc-DTPA was given to assess the postprandial empty function of stomach in 25 patients with NUD. The examinations were repeated in 15 patients with hypomotilitic stomach and gallbladder following administration of Domperidone 20 mg t.i.d for four weeks. The results showed that the empty function of stomach was closely related to the amplitude and frequency of antrum contractile peristaltic waves, all NUD patients who had delayed gastric empty also had hypomotilitic gallbladder. This may be one of the pathophysiologic bases of NUD. The movements of stomach and gallbladder both preprandial and postprandial were synchronous. Domperidone can restore hypomotility of stomach and gallbladder in NUD patients to normal, and the movements of stomach and gallbladder still remained synchronous

    Gastric cancer in the excluded stomach after Roux-en-Y gastric bypass is a rare finding and most reported diagnoses are made via surgery. Endoscopic access to the excluded stomach is difficult, even with balloon-assisted enteroscopy. We present the case of a 74-year-old woman with malignant gastric outlet obstruction of the excluded stomach, 41 years after Roux-en-Y gastric bypass. Minimally invasive access to the excluded stomach was obtained by placement of a percutaneous gastrostomy tube, followed by insertion of a pediatric gastroscope through the gastrostomy tube tract. This novel approach provides minimally invasive access to the excluded stomach in patients with high suspicion of pathology in the excluded stomach, when balloon-assisted enteroscopy is not technically feasible or available.

    Background: The current optimal radiotherapy (RT) planning technique for stomach cancer is controversial. The design of RT for stomach cancer is difficult and differs according to tumor localization. Dosimetric and clinical studies have been performed in patients with different tumor localizations. This may be the main source of inconsistencies in study results. For this reason, we attempted to find the optimal RT technique for patients with stomach cancer in similar locations.

    Little has been known about the contractile characteristics of diabetic stomach. We investigated spontaneous contractions and responses to acetylcholine in the gastric muscle in diabetic patients and non-diabetic control subjects according to the region of stomach. Gastric specimens were obtained from 26 diabetics and 55 controls who underwent gastrectomy at Samsung Medical Center between February 2008 and November 2011. Isometric force measurements were performed using circular muscle strips from the different regions of stomach under basal condition and in response to acetylcholine. Basal tone of control was higher in the proximal stomach than in the distal (0.63 g vs 0.46 g, p = 0.027). However, in diabetics, basal tone was not significantly different between the proximal and distal stomach (0.75 g vs 0.62 g, p = 0.32). The distal stomach of diabetics had higher basal tone and lower frequency than that of control (0.62 g vs 0.46 g, p = 0.049 and 4.0/min vs 4.9/min, p = 0.049, respectively). After exposure to acetylcholine, dose-dependent increases of basal tone, peak, and area under the curve (AUC) were noticed in both proximal and distal stomach of the two groups. In the proximal stomach, however, the dose-dependent increase of basal tone and AUC was less prominent in diabetics than in control. On the contrary to control, the proximal to distal tonic gradient was not observed in diabetic stomach. Diabetic stomach also had lower frequency of spontaneous contraction in the distal stomach and less acetylcholine-induced positive inotropic effect in the proximal stomach than control. © 2013 John Wiley & Sons Ltd.

    Peptidases degrade neuropeptides and thereby limit the duration and extent of their influence. This investigation examined the importance of peptidases in the degradation of the neuropeptide enkephalin in the stomach wall of the rat. Metabolism of [Leu5]- and [D-Ala2][Leu5]enkephalin by gastric membranes was examined in vitro. Degradation of [Tyr1-3H][Leu5]enkephalin was studied in the gastric submucosa of anesthetized and conscious rats in vivo by using a catheter to deliver peptide to tissues and implanted dialysis fibers to collect the metabolites. Specific inhibitors were used to assess the contribution of particular enzymes. [Leu5]- and [Tyr1-3H][Leu5]enkephalin were metabolized by membranes and in the stomach wall by hydrolysis of the Tyr1-Gly2 bond. Degradation was inhibited by the aminopeptidase inhibitor amastatin (10(-5) M in vitro, 10 nmol in vivo). Inhibitors of endopeptidase-24.11 (phosphoramidon) and angiotensin-converting enzyme (captopril) did not inhibit degradation. Metabolism of the aminopeptidase-resistant analogue [D-Ala2][Leu5]enkephalin by membranes was unaffected by amastatin and weakly inhibited by phosphoramidon affected by amastatin and weakly inhibited by phosphoramidon and captopril. A carboxypeptidase removed the COOH-terminal leucine residue and made a substantial contribution to degradation of both peptides by gastric membranes

    Full Text Available Background: The term caustic generally refers to alkaline and the term corrosive generally refers to acidic agents' injury; however, in medical literature caustic is frequently a term applied to both substances. Ingested alkali typically damage the esophagus more than stomach or duodenum, whereas acids usually cause more severe gastric injury. Since esophagus has a slightly alkaline pH, its epithelium is more resistant to acids, so that only 6 to 20% of those who ingest these substances present lesions in this organ. Case : A middle-aged addicted man who drunk hydrochloric acid accidentally had extensive necrosis of the stomach with remarkable sparing of the esophagus on second look exploration. A total gastrectomy with a Roux-en-Y esophago-jejunostomy with feeding jejunostomy was performed. Conclusion : In caustic GI injury, patients who are operated on and found to have no evidence of extensive esophago-gastric necrosis, a biopsy of the posterior gastric wall should be performed to exclude occult injury. If histologically there is a question of viability, a second look operation should be performed within 36 hours.

    IntroductionGastrostomy tube placement for patients requiring long-term nutritional support may be performed using different techniques including endoscopic, surgical, and percutaneous radiologically guided methods. Radiologically inserted gastrostomy (RIG), typically performed when percutaneous endoscopic gastrostomy is not possible, requires proper gastric distension that is achieved by insufflating air through a nasogastric tube. We describe a simple technique to prevent air escape from the stomach during gastrostomy tube placement. To the best of our knowledge, this technique has not yet been described in the literature.Materials and MethodsFour patients with unsuccessful percutaneous endoscopic gastrostomy were referred for fluoroscopic-guided gastrostomy. One patient had a pyriform sinus tumor and three had an ischemic stroke causing dysphagia. Gastric distention was not achieved in the patients due to air escaping into the bowel during the standard RIG procedure. A modified approach using a balloon catheter inflated in the pylorus to avoid air passing into the duodenum permitted successful RIG.ResultsThe modified RIG procedure was successfully carried out in all cases without complications.DiscussionInadequate air distension of the stomach is an unusual event that causes a failure of gastrostomy tube placement and an increased risk of both major and minor complications. The use of a balloon catheter inflated in the first part of the duodenum prevents the air passage into the bowel allowing the correct positioning of the gastrostomy.

    There is a great variety of abdominal calcifications of varying etiology. Among them, calcification in gastric carcinoma is rare. To the best of our knowledge, there has been no previous report of calcifying mucinous adenocarcinoma of the stomach in Korea. In the present communication, we report toe cases of this rare tumor. The first cases was 27 years old female who had anorexia and palpable mass in the epigastrium. By palpation, a firm non-tender large mass was felt in the epigastrium. A plain abdominal film showed numerous punctuate calcifications in the left upper quadrant. Film from an upper G-I series demonstrated findings of advanced gastric carcinoma with multiple punctuate calcifications involving the antrum and body. Gastroscopic biopsy proved the lesion to be mucinous adenocarcinoma (signet ring cell type). The second case was 38 years old female who complicated of nausea, vomiting and weight loss. On physical examination, she appeared normal. Routine laboratory tests were within normal limits. A plain abdominal film reveal stippled calcifications in the left upper quadrant medial to the splenic shadow. The film from an upper G-I series showed a mass in the fundus and upper body of stomach with multiple stippled calcifications along the lesser curvature. Subtotal gastrectomy was performed and the pathologic finding was calcifying mucinous adenocarcinoma (signet ring cell type)

    Full Text Available Ewing sarcoma/primitive neuroectodermal tumor (ES/PNET is a tumor of small round cells arising in skeletal tissues. These tumors rarely arise in the stomach. We present a 31-year-old healthy female patient who was admitted to our surgical ward due to upper gastrointestinal hemorrhage. Upper endoscopy revealed a large ulcerated bleeding mass originating from the lesser curvature. Biopsy revealed tumor cell immunoreactivity positive for CD99, vimentin, and Ki67 (an index of proliferation. These findings were compatible with gastric ES/PNET. The fluorescence in situ hybridization analysis result for the EWSR1 gene rearrangement (11: 22 translocation was positive. The patient refused neoadjuvant treatment and thus underwent an operation during which a mass at the lesser curvature of the stomach was found. The mass was adhering to the pancreatic tail and to the mesentery of the transverse and descending colon. Total gastrectomy, distal pancreatectomy, splenectomy, and left adrenalectomy were done. The patient refused adjuvant treatment. She is free of disease 3 years after surgery.

    Neuromyelitis optica (NMO), or Devic's syndrome, is an autoimmune central nervous system demyelinating disorder primarily affecting the spinal cord and the optic nerves. It is characterized by the presence of NMO antibodies, alongside clinical and radiological findings. NMO and NMO-spectrum disorders (NMO-SD) have been reported in autoimmune disorders, and are infrequently described as a paraneoplastic syndrome with cancers of lung, breast, and carcinoid tumors of the thyroid. We report a patient who presented with severe vomiting, blurring of vision, vertigo, diplopia, left hemiparesis and hemisensory loss and ataxia. She was found to have a longitudinally-extensive demyelinating lesion extending from the medulla to the upper cervical spinal cord on MRI. Her gastric endoscopy revealed carcinoid tumor of the stomach, and classic paraneoplastic antibodies in the serum were negative. She had extremely high serum gastrin level and high titer of NMO IgG autoantibody. The patient made an excellent recovery with tumor resection and immunotherapy, with both clinical and radiological improvement. On rare instances, NMO or NMO-SD may present as a paraneoplastic neurological syndrome associated with carcinoid tumor of the stomach.

    Peristaltic contraction waves (PCWs) on the stomach wall induce flow that mixes gastric content. Our aim was to evaluate the relationship among PCWs, flow structure and mixing efficiency. We used 2D lattice Boltzmann method with realistic stomach geometry model and a moving boundary condition algorithm. PCWs generate two dominant viscous flow patterns: jet-like retrograde flow through a PCW driven by only fractions of a mmHg pressure drop, and recirculating eddying flow. Both flow patterns are important in mixing, i.e., the rate of spreading of fluid particles. The jet-like flow induces high strain that rapidly separates particles, whereas the eddying motions transport particles across the flow domain. Both flow strength and mixing are sensitive to occlusion and width of the PCWs; retrograde flow was also sensitive to downstream details. We conclude that PCWs drive eddying motions and generate small pressure gradients that drive fluid retrograde against frictional resistance. Both the retrograde jets and the eddying motions contribute to mixing, albeit in different ways. Flow, and consequently mixing, is sensitive to details of PCW geometry.

    This study aimed to evaluate the relationship between biliary excreted contrast media in the stomach and the presence of bile reflux gastritis. Consecutive 111 patients who underwent both gadoxetic acid-enhanced magnetic resonance cholangiography (gadoxetic MRC) and gastric endoscopy were included in this study. We performed a review of the gadoxetic-MRC image sets acquired 60 minutes after intravenous injection of contrast media and endoscopic images. We recorded amount of contrast media in the stomach. The sensitivity, specificity, and accuracy of duodenogastric bile reflux diagnosis were evaluated for the gadoxetic MRC. Statistical analysis was performed using the Fisher exact test and the linear-by-linear association test. Among the 111 patients, 39 had 60-minute delayed images showing the presence of contrast media in the stomach. Of these 39 patients, 13 had bile reflux gastritis and 5 showed bile in the stomach without evidence of erythematous gastritis. Of the 72 patients who did not show contrast media in the stomach, none had bile reflux gastritis and 2 patients showed bile staining in the stomach without evidence of erythematous gastritis. Bile reflux gastritis was significantly more frequent in patients with contrast media in the stomach on gadoxetic MRC than in those without. Patients with high-grade extension of contrast media in the stomach had significantly frequent bile reflux gastritis than did those with low-grade extension. Biliary excreted contrast media in the stomach on 60-minute delayed gadoxetic MRC has a correlation with the presence of bile reflux gastritis on endoscopic examination.

    The association between stomach cancer and colorectal cancer is controversial. The purpose of this study was to determine the synchronous prevalence of colorectal neoplasms in patients with stomach cancer. A total of 123 patients with stomach cancer (86 male) and 246 consecutive, age- and sex-matched persons without stomach cancer were analyzed from July 2005 to June 2010. All of them underwent colonoscopy within 6 months after undergoing gastroscopy. The prevalence of colorectal neoplasms was significantly higher in the stomach cancer group (35.8%) than in the control group (17.9%) (P stomach cancer (odds ratio [OR], 3.10; 95% confidence interval [CI], 1.71 to 5.63). In particular, the difference in the prevalence of colorectal neoplasms was more prominent in the patients above 50 years old (OR, 3.54; 95% CI, 1.80 to 6.98). The results showed that the synchronous prevalence of colorectal neoplasms was higher in patients with stomach cancer than in those without stomach cancer. Therefore, patients with stomach cancer should be regarded as a high-risk group for colorectal neoplasms, and colonoscopy should be recommended for screening.

  12. Resting-state fMRI in sleeping infants more closely resembles adult sleep than adult wakefulness.

    Directory of Open Access Journals (Sweden)

    Anish Mitra

    Full Text Available Resting state functional magnetic resonance imaging (rs-fMRI in infants enables important studies of functional brain organization early in human development. However, rs-fMRI in infants has universally been obtained during sleep to reduce participant motion artifact, raising the question of whether differences in functional organization between awake adults and sleeping infants that are commonly attributed to development may instead derive, at least in part, from sleep. This question is especially important as rs-fMRI differences in adult wake vs. sleep are well documented. To investigate this question, we compared functional connectivity and BOLD signal propagation patterns in 6, 12, and 24 month old sleeping infants with patterns in adult wakefulness and non-REM sleep. We find that important functional connectivity features seen during infant sleep closely resemble those seen during adult sleep, including reduced default mode network functional connectivity. However, we also find differences between infant and adult sleep, especially in thalamic BOLD signal propagation patterns. These findings highlight the importance of considering sleep state when drawing developmental inferences in infant rs-fMRI.

    Increased disease susceptibility during early life has been linked to immune immaturity, regulatory T-cell/TH2 immune biasing and hyporesponsiveness. The contribution of myeloid derived suppressor cells (MDSCs) remains uninvestigated. Here, we assessed peripheral MDSC in HIV-infected and -uninfected children with tuberculosis (TB) disease before, during and after TB treatment, along with matched household contacts (HHCs), HIV-exposed, -infected and -uninfected children without recent TB exposure. Serum analytes and enzymes associated with MDSC accumulation/activation/function were measured by colorimetric- and fluorescence arrays. Peripheral frequencies of cells phenotypically resembling MDSCs were significantly increased in HIV-exposed uninfected (HEU) and M.tb-infected children, but peaked in children with TB disease and remained high following treatment. MDSC in HIV-infected (HI) children were similar to unexposed uninfected controls; however, HAART-mediated MDSC restoration to control levels could not be disregarded. Increased MDSC frequencies in HHC coincided with enhanced indoleamine-pyrrole-2,3-dioxygenase (IDO), whereas increased MDSC in TB cases were linked to heightened IDO and arginase-1. Increased MDSC were paralleled by reduced plasma IP-10 and thrombospondin-2 levels in HEU and significantly increased plasma IL-6 in HI HHC. Current investigations into MDSC-targeted treatment strategies, together with functional analyses of MDSCs, could endorse these cells as novel innate immune regulatory mechanism of infant HIV/TB susceptibility. © 2016 WILEY-VCH Verlag GmbH & Co.

    The aim of this study was to investigate the presence of a patent processus vaginalis (PPV) in children of late childhood and pre-adolescence presenting with new onset hydrocele. All males with hydrocele presenting at our department from January 2011 to January 2013 were followed. Patients with secondary hydroceles were excluded. Demographic data, medical history, clinical symptoms and signs relative to their pathology and U/S findings were recorded. According to their indications, patients were either operated or followed up. Patients surgically treated, consisted our study group. Sixty patients were identified. Thirteen were followed until resolution of their hydrocele. Forty-seven patients were surgically treated. Twenty-seven had right sided hydrocele (57.44%), 13 had left sided hydrocele (27.66%) whereas in 7 patients the hydroceles were bilateral (14.9%). All patients were operated by an inguinal approach. In all 9 patients (19.14%) presenting with new-onset hydrocele at the age >10 years (range: 10-15 years), intraoperative exploration did not reveal a PPV. All patients were followed at least for 6 months post-operatively. Early evidence shows that primary new onset hydroceles presenting in late childhood and pre-adolescence seem to be non-communicating and resemble the adult type hydrocele pathology.

  15. Resembling a viper: implications of mimicry for conservation of the endangered smooth snake.

    Science.gov (United States)

    Valkonen, Janne K; Mappes, Johanna

    2014-12-01

    The phenomenon of Batesian mimicry, where a palatable animal gains protection against predation by resembling an unpalatable model, has been a core interest of evolutionary biologists for 150 years. An extensive range of studies has focused on revealing mechanistic aspects of mimicry (shared education and generalization of predators) and the evolutionary dynamics of mimicry systems (co-operation vs. conflict) and revealed that protective mimicry is widespread and is important for individual fitness. However, according to our knowledge, there are no case studies where mimicry theories have been applied to conservation of mimetic species. Theoretically, mimicry affects, for example, frequency dependency of predator avoidance learning and human induced mortality. We examined the case of the protected, endangered, nonvenomous smooth snake (Coronella austriaca) that mimics the nonprotected venomous adder (Vipera berus), both of which occur in the Åland archipelago, Finland. To quantify the added predation risk on smooth snakes caused by the rarity of vipers, we calculated risk estimates from experimental data. Resemblance of vipers enhances survival of smooth snakes against bird predation because many predators avoid touching venomous vipers. Mimetic resemblance is however disadvantageous against human predators, who kill venomous vipers and accidentally kill endangered, protected smooth snakes. We found that the effective population size of the adders in Åland is very low relative to its smooth snake mimic (28.93 and 41.35, respectively).Because Batesian mimicry is advantageous for the mimic only if model species exist in sufficiently high numbers, it is likely that the conservation program for smooth snakes will fail if adders continue to be destroyed. Understanding the population consequences of mimetic species may be crucial to the success of endangered species conservation. We suggest that when a Batesian mimic requires protection, conservation planners should

    We have previously developed three logistic regression models for discriminating intracranial aneurysm rupture status from 119 aneurysms based on hemodynamic-morphological parameters. In this study we exploit their use as a tool for predicting the risk of rupture of aneurysms with a defined Rupture Resemblance Score (RRS). We collected three-dimensional images of 85 consecutive aneurysms, applied the three regression models and compared model performance at predicting rupture status against anecdotal metrics (aneurysm size and aspect ratio). We then reinterpreted the model-predicted probability as RRS, where the higher the score the closer the resemblance to previously known rupture components, and applied the RRS prospectively to four unruptured aneurysms with borderline treatment decisions. All three models yielded excellent sensitivity (0.78-0.83) and specificity (0.78-0.84) at a cutoff score of 50%, whereas aneurysm size and aspect ratio showed poor sensitivities (0.28 and 0.33, respectively). Lowering the cutoff score to 30% improved sensitivity to 0.90. The RRS identified most of the ruptured aneurysms and also some unruptured ones that closely resembled ruptured aneurysms hemodynamically and/or morphologically. The prospective application of the RRS to unruptured aneurysms shows that it could provide additional insights for treatment decisions. Previous regression models based on hemodynamic-morphological parameters are able to discriminate rupture in a new cohort in the same population. A higher probability of rupture is associated with larger size ratio, lower normalized wall shear stress and higher oscillatory shear index. The RRS could potentially stratify rupture risk and assist in treatment decision-making for unruptured aneurysms. Published by the BMJ Publishing Group Limited.

  17. Metastasis of a pleural mesothelioma to a hyperplastic stomach polyp: an increase of vimentin expression is seen during a gain in deciduoid morphology

    Directory of Open Access Journals (Sweden)

    Peter Vogt

    2011-10-01

    Full Text Available Deciduoid mesothelioma is a rare variant of the epithelioid histotype spectrum, resembling decidua of gravid uterus. It is found in the peritoneum of young women, but also in the pleura of elderly people. Histotype plasticity from epithelioid to sarcomatoid mesothelioma may be considered as epithelial-mesenchymal transition (EMT. A full autopsy was performed and mesothelioma infiltrates were analysed by immunohistochemistry. The metastasis of an epithelioid pleural mesothelioma to a hyperplastic polyp of the stomach is presented in this autopsy case. Deciduoid morphology increased during tumour progression and metastasis. The increase in eosinophilic cytoplasm correlated with the upregulation of the intermediate filament vimentin. High expression of vimentin was found in both central and superficial periglandular regions of the polyp. High vimentin expression also can occur in epithelioid rather than sarcomatoid differentiation. Thus, although vimentin is considered to be the major EMT marker, additional pathways must regulate its expression.

    The authors have isolated genomic and cDNA clones for a Drosophila gene resembling the human β-amyloid precursor protein (APP). This gene produces a nervous system-enriched 6.5-kilobase transcript. Sequencing of cDNAs derived from the 6.5-kilobase transcript predicts an 886-amino acid polypeptide. This polypeptide contains a putative transmembrane domain and exhibits strong sequence similarity to cytoplasmic and extracellular regions of the human β-amyloid precursor protein. There is a high probability that this Drosophila gene corresponds to the essential Drosophila locus vnd, a gene required for embryonic nervous system development

    2014-12-01

    A phenomenon resembling natural ball lightning can be produced via electrical arcing through silicon. We use lump silicon instead of silicon wafers to achieve higher production rates and larger, longer-lived luminous balls than previously reported. The luminous balls consist of a silicon core surrounded by a porous network of loosely bound silicon dioxide nanoparticles. We find that the balls carry a small net charge on the order of 10-12 C and propose that the nanoparticles are electrostatically bound to the core due to this charge.

    Post-aggression consolation is assumed to occur in humans as well as in chimpanzees. While consolation following peer aggression has been observed in children, systematic evidence of consolation in human adults is rare. We used surveillance camera footage of the immediate aftermath of nonfatal...... to be consoled. Furthermore, we show that high levels of threat during the robbery increased the likelihood of receiving consolation afterwards. These patterns resemble post-aggression consolation in chimpanzees and suggest that emotions of empathic concern are involved in consolation across humans...... and chimpanzees....

    We are reporting an unusual case of secondary syphilis, in a homosexual male patient, which resembled borderline lepromatous leprosy, and in whom the diagnosis was considered on clinical grounds. The patient also had concomitant HIV infection, with asymptomatic neurosyphilis. His rapid plasma reagin test was reactive in 1:128 dilution. He improved with three standard, weekly injections of benzathine penicillin, along with 2 g of intravenous ceftriaxone daily for 15 days. This case is being reported to highlight the need for a high index of suspicion in diagnosing unusual cases of secondary syphilis, especially in those with concomitant HIV infection. PMID:26692613

    To analyze the national and provincial disease burden on stomach cancer in the Chinese population, in 1990 and 2013. Data related to province-specific burden of disease in China was used to analyze the standardized incidence and mortality of stomach cancer in 2013. Parameters as incidence, mortality, disability-adjusted life years (DALY), years of life lost due to premature mortality (YLL) and years lived with disability (YLD) on stomach cancer in China in 1990 and 2013, were analyzed while the standardized incidence and mortality of stomach cancer in 1990 and 2013 and the changing patterns in each province were described. In 2013, there were 371 100 new cases of stomach cancer and 317 800 cases died from stomach cancer in China. Figures on the standardized incidence (26.84/100 000), mortality rate (23.55/100 000) and DALY rate (464.47/100 000) all increased with age. Between 1990 and 2013, the standardized incidence rates in men were all higher than that in women (2.03-2.67 times) but both showed a decreasing trend. Under the reported figures, 317 800 people died from stomach cancer in 2013, with an increase of 13.15%. The number of deaths was 182 700, in 1990. From 1990 to 2013, the standardized mortality rate, DALY and DALY rate decreased in both genders,with more seen in women than in men. The top three provinces that having the highest stomach cancer standardized incidences and mortality in 2013 were Qinghai, Anhui, Gansu. The top three provinces with the most reduction of figures appeared in Tianjin, Shanghai and Zhejiang. Compared with those in 1990, the standardized mortality decreased in all the provinces, in 2013. The disease burden of stomach cancer in China remained at high level in 2013. Compared with those in 1990, the disease burden of stomach cancer decreased in 2013. The standardized mortality of stomach cancer in all the provinces had decreased but the provincial differences still existed.

    Full Text Available Primary (AL amyloidosis of the gastrointestinal tract is relatively rare, and symptomatic amyloidosis of the stomach is even more seldom. We present the case of a patient who was referred to upper endoscopy because of weight loss, nausea, and vomiting. Large areas of intramucosal hemorrhages were seen, and biopsies resulted in profuse bleeding stopped with endoscopic clips. The biopsies showed amyloid depositions and further workup revealed that the patient also had cardiac and neuropathic involvements. The patient started treatment with dexamethasone, melphalan and bortezomib. After treatment was started the nausea and epigastric discomfort improved, and a reduction in the biochemical markers troponin T, NT-proBNP, and M-component was observed. Gastric amyloidosis is rarely seen at upper endoscopy in patients without a previously established diagnosis, but the unusual endoscopic findings and bleeding tendency after biopsy should be kept in mind by gastroenterologists.

    Full Text Available The fact that gastric surgery is at the moment the most effective treatment to fight against obesity highlights the relevance of gastric derived proteins as potential targets to treat this pathology. Taking advantage of a previously established gastric explant model for endocrine studies, the proteomic analysis of gastric secretome was performed. To validate this gastric explant system for proteomic analysis, the identification of ghrelin, a classical gastric derived peptide, was performed by MS. In addition, the differential analysis of gastric secretomes under differential nutritional status (control feeding vs fasting vs re-feeding was performed. The MS identified proteins are showed in the present manuscript. The data supplied in this article is related to the research article entitled “Comparative secretome analysis of rat stomach under different nutritional status” [1].

    Radioimmunologic assays of blood serum carcinoembryonic antigen (CEA) level were conducted at major stages of treatment of gastric cancer by subtotal stomach resection and gastrectomy with preliminary cryotreatment and thawing of tumor. A short-term rise in CEA level occurred in 53.9 % of cases 3-4 days after combined therapy. A decrease in CEA concentration at discharge from hospital as compared with preoperative level and that registered 3-4 days after operation was observed in 50 and 75 % of cases of combined therapy, respectively, and 47.5 and 37.5 % of controls (surgery without cryotreatment). There was nocorrelation between cryotreatment and changes in CEA level in gastric ulcer patients

    Mixing fluid in a container at low Reynolds number--in an inertialess environment--is not a trivial task. Reciprocating motions merely lead to cycles of mixing and unmixing, so continuous rotation, as used in many technological applications, would appear to be necessary. However, there is another solution: movement of the walls in a cyclical fashion to introduce a geometric phase. We show using journal-bearing flow as a model that such geometric mixing is a general tool for using deformable boundaries that return to the same position to mix fluid at low Reynolds number. We then simulate a biological example: we show that mixing in the stomach functions because of the "belly phase," peristaltic movement of the walls in a cyclical fashion introduces a geometric phase that avoids unmixing.

    Isolated gastric glands prepared from human and rabbit stomach secrete lipase in response to secretagogues. They have investigated the localization of this enzyme in three species (rabbit, baboon, guinea pig). Gastric mucosa was sampled from the cardia (C), fundus-smooth (FS), fundus-ruggae (FR) and the antral area (A). Lipase activity was measured in mucosal homogenates using 3 H-triolein as substrate and is expressed in units (U) = nmols free fatty acid released/min/mg wet weight. The localization of lipase is compared with that of pepsin (measured by hydrolysis of 2% hemoglobin at pH 1.8 and expressed in I.U.). Lipase is localized in a well defined area in the rabbit and is diffusely distributed in both guinea pig and baboon. The distribution of lipase and pepsin containing cells differs in all three species. The cellular origin of gastric lipase remains to be determined

    Knowledge of milk transfer from mother to offspring and early solid food ingestions in mammals allows for a greater understanding of the factors affecting transition to nutritional independence and pre-weaning growth and survival. Yet studies monitoring suckling behaviour have often relied on visual observations, which might not accurately represent milk intake. We assessed the use of stomach temperature telemetry to monitor suckling and foraging behaviour in free-ranging harbour seal (Phoca vitulina) pups during lactation. Stomach temperature declines were analysed using principal component and cluster analyses, as well as trials using simulated stomachs resulting in a precise classification of stomach temperature drops into milk, seawater and solid food ingestions. Seawater and solid food ingestions represented on average 15.3±1.6% [0–40.0%] and 0.7±0.2% [0–13.0%], respectively, of individual ingestions. Overall, 63.7% of milk ingestions occurred while the pups were in the water, of which 13.9% were preceded by seawater ingestion. The average time between subsequent ingestions was significantly less for seawater than for milk ingestions. These results suggest that seawater ingestion might represent collateral ingestion during aquatic suckling attempts. Alternatively, as solid food ingestions (n = 19) were observed among 7 pups, seawater ingestion could result from missed prey capture attempts. This study shows that some harbour seals start ingesting prey while still being nursed, indicating that weaning occurs more gradually than previously thought in this species. Stomach temperature telemetry represents a promising method to study suckling behaviour in wild mammals and transition to nutritional independence in various endotherm species. PMID:24587327

    Examinations for parietal cell antibody (PCA) were performed on 1334 subjects of the Adult Health Study (AHS), Hiroshima, during a 1-year period. Findings revealed PCA in 112 subjects (8.4%), but no difference in frequency was noted by sex. The relationship of PCA to age showed the positive rate to be significantly higher in those age 50 or over than in those under 50. No correlation was noted between estimated A-bomb exposure dose and PCA frequency. PCA was found in 58 (11.6%) of the 502 cases presenting achlorhydria on tubeless gastric analysis, and particularly in the age 50 and over group, PCA was demonstrated in 43 (14.2%) of the 302 subjects presenting achlorhydria, which is a significant difference compared with the under 50 age group in which PCA was demonstrated in 15 (7.5%) of 200 such subjects. PCA was detected in 11 (7.2%) of 152 subjects with abnormal, or low, serum pepsinogen levels and in 20 (16.3%) of 123 subjects with high levels. The frequency of positive PCA was higher in patients diagnosed on upper gastrointestinal (GI) series as atrophic gastritis than in patients diagnosed as some other gastric disorder. PCA was negative in both of the two cases in whom a definite diagnosis of stomach cancer was established. However, in light of the finding of abnormal Diagnex Blue (DB) tests and positive PCA at a high frequency in the gastritis group and reports that gastritis provides the groundwork for stomach cancer, it is considered that care should be taken in cases with findings of abnormal DB test, abnormal serum pepsinogen levels, and positive PCA.

    Full Text Available The purpose of this article was to write a literature review on the possibility of genetic typing of patients with stomach cancer at the current stage of the domestic molecular genetic laboratory service development. Materials and мethods. The combination of molecular factors in gastric cancer (GC used in the work was based on their relevance in clinical and experimental studies in case of GC over the last 10 years. The frequency of their use in foreign and domestic research works cited by PubMed and Google Scholar Systems, as well as our own research, was estimated. Results. Signs of genetically-stable stomach cancer (GSGC were: a combination of low, below 10 %, p53 oncoprotein expression, the presence of at least weak VEGFR-C expression, a high, more than 20 %, proliferative tumor index. Chromosomal-unstable tumors were characterized not only by the presence of positive expression of crbB2, but also by more than 10 % expression of p53 oncoprotein and complete absence of VEGFR-C expression. Microsatellite-unstable GC (MUGC was characterized by negative expression of the oncoprotein crbB2, positive p53, lack of VEGFR – C. Epstein–Barr virus-associated GC (EBVAGC was characterized by the absence of the VEGFR-C indicator protein and by the presence of crbB2 positive expression, in combination with a low, below 10 % expression, of the p53 oncoprotein. Conclusions. Understanding the nature of the GC various genetic variants makes possible two basic types of complex treatment individualization: the individualization of chemotherapy and the personification of the surgical modalities.

    Many methods have been developed to measure the antioxidant capacity of foods under non physiological-relevant conditions. In this study, three methods (TEAC OH , GEAC RED and TEAC AAPH ) are developed to measure antioxidant capacity at physiological pH, using indigo carmine as a redox dye. TEAC OH and TEAC AAPH determine foodstuffs' scavenging capacity against hydroxyl (OH) and AAPH radicals, while the third method measures the global reducing capacity of the sample. The results obtained for commercial teas, commercial beverages containing tea as the main ingredient and different solid foods (spinach, onion, salami, etc.) were compared with well-established protocols. The new methods demonstrated good linearity-reproducibility, providing reliable data about the antioxidant capacity of foods under physiological-resembling conditions. The new methods were also useful for evaluating the antioxidant capacity of human plasma after acute intake of tea. The physiological-resembling conditions of these assays and the use of absorbance readings make them suitable for application by any laboratory. Copyright © 2017 Elsevier Ltd. All rights reserved.

  13. Familial resemblance of borderline personality disorder features: genetic or cultural transmission?

    Marijn A Distel

    Full Text Available Borderline personality disorder is a severe personality disorder for which genetic research has been limited to family studies and classical twin studies. These studies indicate that genetic effects explain 35 to 45% of the variance in borderline personality disorder and borderline personality features. However, effects of non-additive (dominance genetic factors, non-random mating and cultural transmission have generally not been explored. In the present study an extended twin-family design was applied to self-report data of twins (N = 5,017 and their siblings (N = 1,266, parents (N = 3,064 and spouses (N = 939 from 4,015 families, to estimate the effects of additive and non-additive genetic and environmental factors, cultural transmission and non-random mating on individual differences in borderline personality features. Results showed that resemblance among biological relatives could completely be attributed to genetic effects. Variation in borderline personality features was explained by additive genetic (21%; 95% CI 17-26% and dominant genetic (24%; 95% CI 17-31% factors. Environmental influences (55%; 95% CI 51-60% explained the remaining variance. Significant resemblance between spouses was observed, which was best explained by phenotypic assortative mating, but it had only a small effect on the genetic variance (1% of the total variance. There was no effect of cultural transmission from parents to offspring.

    Although microRNAs (miRNAs) are postulated to fine-tune many developmental processes, their relationships with specific targets and tissues remain largely undefined. The mesenchymal transcription factor Barx1 controls spleen and stomach morphogenesis and is required to specify stomach-specific epithelium in adjacent endoderm. Barx1 expression is precisely regulated in space and time, with a sharp drop in stomach levels after epithelial specification. We tested the hypothesis that specific miRNAs mediate this marked decline in Barx1 levels. Depletion of the miRNA-processing enzyme Dicer in cultured stomach mesenchyme and conditional Dicer gene deletion in mice significantly increased Barx1 levels, disrupted stomach and intestine development and caused spleen agenesis. Computational and experimental studies identified miR-7a and miR-203 as candidate miRNAs that regulate Barx1 and are expressed in inverse proportion to it in the fetal mouse stomach. Through specific interactions with cognate sequences in the Barx1 3′ untranslated region, miR-7a and miR-203 repress Barx1 expression in stomach mesenchymal cells and its function in inducing gastric epithelium. These results indicate that miRNAs are required for proper digestive tract organogenesis and that miR-7a and miR-203 control expression of the stomach homeotic regulator Barx1. PMID:21307095

    Full Text Available Intraluminal gastric and colonic metastases of the breast cancer are very rare and may sometimes prove a  diagnostic dilemma to distinguish from primary gastric and colonic cancers. It is important to make the distinction in order to navigate the proper treatment approach, which is a systemic treatment rather than surgery if the disease is me- tastatic. The spread to the gastrointestinal (GI tract is more frequent in lobular histology and according to a number of investigators, it is related to a particular tropism of lobular cells toward gastrointestinal mucosa. Any region of GI tract may be involved, from the tongue to the anus. Over the last decade, among the 1,100 breast cancer cases registered at our institutions, we diagnosed four patients with breast cancer who had metastases to the stomach and/or colon and presented symptoms that simulated primary gastrointestinal cancer. A total of 84 out of the 1,100 patients experienced invasive lobular histology. Among the four patients with GI tract metastases, three were diagnosed with lobular histology – two of whom had the signet ring cell subtype. The remaining patient was diagnosed with triple negative invasive ductal carcinoma; however, it clinically resembled invasive lobular carcinoma. Clinical and pathological features of these cases, as well as the review of related literature are discussed in this report.

    We compared the ability to extract all stomach contents by using stomach tubes or gastric lavage to sample diets from blue catfish Ictalurus furcatus and flathead catfish Pylodictus olivarus. Pulsed gastric lavage (PGL) removed a significantly greater proportion of stomach content mass (95.6%) from blue catfish than did stomach tubes (14.6%). Percent mass of flathead catfish contents removed with PGL (96.0%) was not significantly different from that removed with stomach tubes (86.9%). Based on the greater effectiveness of PGL for blue catfish, combined with a shorter mean time required per sample (69 versus 118 s) and the better preservation of extracted diet material, we recommend using PGL as a nonlethal technique to collect diet samples from large catfishes.

    Full Text Available Abstract Background Metastatic tumours of the stomach present a clinical dilemma for the surgeon. Palliative surgical resection can alleviate symptoms and prolong survival in selected patients. However, previous studies have used open methods of surgical resection with potentially high morbidity and mortality. We describe the use of laparoscopic wedge resection of the stomach for palliative resection of metastatic melanoma to highlight the benefits of this technique. Case presentation A 58 year old male was investigated for iron deficiency anaemia while under treatment for pulmonary metastatic malignant melanoma. An upper gastrointestinal endoscopy revealed a 5 cm diameter ulcer on the anterior wall of the stomach, biopsies from the ulcer confirmed metastatic melanoma. Laparoscopic wedge resection of the stomach lesion was performed without complication. Conclusion Laparoscopic approach has many benefits and is useful for the palliative resection of rare tumours of the stomach in order to preserve the quality of life. Its use should be considered in selected patients.

    Anastellin is a carboxy-terminal fragment of the 1st FN3 domain from human fibronectin. It is capable of polymerizing fibronectin in vitro, and it displays anti-tumor, antimetastatic and anti-angiogenic properties in vivo. We have determined the structure of anastellin using nuclear magnetic resonance spectroscopy and identified residues critical for its activity. Anastellin exhibits dynamic fluctuations and conformational exchange in solution. Its overall topology is very similar to the corresponding region of full-length FN3 domains. However, its hydrophobic core becomes solvent accessible and some of its -strands lose their protection against hydrogen bonding to -strands from other molecules. These features seem to be relevant for the fibronectin polymerization activity of anastellin and resemble the characteristics of amyloid fibril precursors. We suggest that this analogy is not random and may reflect similarities between fibronectin and amyloid fibril formation.

    A 5-year-old male captive corn snake (Pantherophis guttatus) with caudal coelomic swelling was admitted for surgical treatment. Laparotomy revealed a 5 × 4 × 2.5 cm, firm, expansile, irregularly shaped mass arising from the middle portion of the right kidney with a mild lobulated pattern and mottled white-to-tan. Microscopically, the mass was composed of numerous bizarre angulated tubules of polygonal neoplastic cells separated by a scirrhous stroma with remarkable heterophilic infiltrates. The neoplastic cells were nonciliated and mucin secreting, with abundant brightly eosinophilic cytoplasm. There were marked cellular and nuclear atypia, frequent cell individualization, and stromal invasion, indicative of malignant behavior, which was confirmed by metastasis to the left kidney 1.5 months postoperatively. Both neoplastic epithelial cells and mesenchymal cells contributing to the scirrhous stroma had variable immunopositivity for pan-cytokeratin. The neoplasm was considered a renal adenocarcinoma resembling human collecting duct carcinoma. © 2016 The Author(s).

  11. Westermarck, Freud, and the incest taboo: does familial resemblance activate sexual attraction?

    Science.gov (United States)

    Fraley, R Chris; Marks, Michael J

    2010-09-01

    Evolutionary psychological theories assume that sexual aversions toward kin are triggered by a nonconscious mechanism that estimates the genetic relatedness between self and other. This article presents an alternative perspective that assumes that incest avoidance arises from consciously acknowledged taboos and that when awareness of the relationship between self and other is bypassed, people find individuals who resemble their kin more sexually appealing. Three experiments demonstrate that people find others more sexually attractive if they have just been subliminally exposed to an image of their opposite-sex parent (Experiment 1) or if the face being rated is a composite image based on the self (Experiment 2). This finding is reversed when people are aware of the implied genetic relationship (Experiment 3). These findings have implications for a century-old debate between E. Westermarck and S. Freud, as well as contemporary research on evolution, mate choice, and sexual imprinting.

    Full Text Available Scabies is an infestation caused by Sarcoptes scabiei and characterised by polymorphous lesions that may include burrows, papules, pustules, crusts and excoriations. Several pruritic diseases may be confused with scabies. Herein, we present a case of scabies with lesions resembling perforating folliculitis diagnosed on the basis of both clinical and histopathological view. A 72-year-old man with type 2 diabetes mellitus and receiving hemodialysis for ten years due to end-stage renal disease was admitted to our dermatology department with a 6-month history of severe pruritus. Based on the results of skin biopsy revealing Sarcoptes scabiei in the epidermis, the patient was diagnosed as scabies and was successfully treated with 5% permethrin. This case is presented to emphasize that scabies should be considered in the differential diagnosis in cases of chronic pruritus.

  13. Evaluation and clinical significance of the stomach age model for evaluating aging of the stomach-a multicenter study in China

    2014-01-01

    Background A higher prevalence of chronic atrophic gastritis (CAG) occurs in younger adults in Asia. We used Stomach Age to examine the different mechanisms of CAG between younger adults and elderly individuals, and established a simple model of cancer risk that can be applied to CAG surveillance. Methods Stomach Age was determined by FISH examination of telomere length in stomach biopsies. Δψm was also determined by flow cytometry. Sixty volunteers were used to confirm the linear relationship between telomere length and age while 120 subjects were used to build a mathematical model by a multivariate analysis. Overall, 146 subjects were used to evaluate the validity of the model, and 1,007 subjects were used to evaluate the relationship between prognosis and Δage (calculated from the mathematical model). ROC curves were used to evaluate the relationship between prognosis and Δage and to determine the cut-off point for Δage. Results We established that a tight linear relationship between the telomere length and the age. The telomere length was obvious different between patients with and without CAG even in the same age. Δψm decreased in individuals whose Stomach Age was greater than real age, especially in younger adults. A mathematical model of Stomach Age (real age + Δage) was successfully constructed which was easy to apply in clinical work. A higher Δage was correlated with a worse outcome. The criterion of Δage >3.11 should be considered as the cut-off to select the subgroup of patients who require endoscopic surveillance. Conclusion Variation in Stomach Age between individuals of the same biological age was confirmed. Attention should be paid to those with a greater Stomach Age, especially in younger adults. The Δage in the Simple Model can be used as a criterion to select CAG patients for gastric cancer surveillance. PMID:25057261

    Annually, there are more than 6 million deaths from a type of malignant neoplasia worldwide. In developing countries, the highest rates of incidence of malignant neoplasias are uterine cervical cancer, stomach, lung, esophagus, pharynx, and liver cancers. Recent estimates on the incidence of cancer worldwide show that, in 1990, stomach cancer (SC) was the second most frequent type of cancer (900,000 new cases annually). Rates of incidence have decreased consistently in nearly all areas of the world. In Mexico, however, rates of incidence and mortality have increased gradually between 1980 and 1997; in 1995, 4,685 people died of SC in Mexico. This report presents a descriptive analysis of SC mortality in Mexico. A mortality database edited from the electronic files of the National Institute of Informatics, Statistics and Geography (INEGI) in Mexico was used; population denominators were edited by the Mexican National Population Council (Conapo). Adjusted mortality rates, taking as standard of reference the population of Mexico City by sex, year, and 10-year age groups were calculated as well as the sex ratio for the 1980-1997 period. To evaluate the magnitude of risks by state, the standardized mortality ratio (SMR) was calculated; prematurity was evaluated through the potential lost-life years index (PLLYI). The analysis was carried out using the Excel and Stata 5.0 software programs. During the years from 1980 to 1997, in Mexico the total number of deaths from SC was 76,315. The male:female ratio was 1.2:1.0. SMR by state showed that the states of Yucatán, Sonora, Zacatecas, Michoacán, and Chiapas had higher mortality rates. The PLLYI was higher for males in the states of Chiapas, Sonora, Chihuahua, Zacatecas, and Southern Baja California, and higher for females in Chiapas, Oaxaca, Yucatán, Puebla, and Campeche. World statistics on mortality caused by SC suggest a decreasing trend. Findings for this study show an increase in the adjusted mortality rates by SC

     Most gastric bezoars can be treated with endoscopic fragmentation combined with or without cola dissolution, whereas laparotomy or laparoscopic surgery is generally inevitable for small intestinal bezoars because they cause small bowel obstruction. Therefore, early diagnosis and management of gastric bezoars are necessary to prevent bezoar-induced ileus. To investigate the incidence of overlooked gastric bezoars during the initial esophagogastroduodenoscopy, we retrospectively reviewed the cases of 27 patients diagnosed with gastrointestinal bezoars. The bezoars were diagnosed using esophagogastroduodenoscopy (n=25), abdominal ultrasonography (n=1), and barium follow-through examination (n=1). Bezoars were overlooked in 9/25 patients (36.0%) during the initial endoscopy examination because the bezoars were covered with debris in the stomach. Of the 9 patients, 8 had concomitant gastric ulcers, and the other patient had gastric lymphoma. Although a computed tomography (CT) scan was performed before the second-look endoscopy in 8 of the 9 patients, the bezoars were mistaken as food debris on CT findings and were overlooked in these patients. In conclusion, gastric bezoars may not be discovered during the initial esophagogastroduodenoscopy and CT scan. In cases with debris in the stomach, second-look endoscopy is essential to detect bezoars.

  20. Rhythmicity in mice selected for extremes in stress reactivity: behavioural, endocrine and sleep changes resembling endophenotypes of major depression.

    Directory of Open Access Journals (Sweden)

    Chadi Touma

    Full Text Available Dysregulation of the hypothalamic-pituitary-adrenal (HPA axis, including hyper- or hypo-activity of the stress hormone system, plays a critical role in the pathophysiology of mood disorders such as major depression (MD. Further biological hallmarks of MD are disturbances in circadian rhythms and sleep architecture. Applying a translational approach, an animal model has recently been developed, focusing on the deviation in sensitivity to stressful encounters. This so-called 'stress reactivity' (SR mouse model consists of three separate breeding lines selected for either high (HR, intermediate (IR, or low (LR corticosterone increase in response to stressors.In order to contribute to the validation of the SR mouse model, our study combined the analysis of behavioural and HPA axis rhythmicity with sleep-EEG recordings in the HR/IR/LR mouse lines. We found that hyper-responsiveness to stressors was associated with psychomotor alterations (increased locomotor activity and exploration towards the end of the resting period, resembling symptoms like restlessness, sleep continuity disturbances and early awakenings that are commonly observed in melancholic depression. Additionally, HR mice also showed neuroendocrine abnormalities similar to symptoms of MD patients such as reduced amplitude of the circadian glucocorticoid rhythm and elevated trough levels. The sleep-EEG analyses, furthermore, revealed changes in rapid eye movement (REM and non-REM sleep as well as slow wave activity, indicative of reduced sleep efficacy and REM sleep disinhibition in HR mice.Thus, we could show that by selectively breeding mice for extremes in stress reactivity, clinically relevant endophenotypes of MD can be modelled. Given the importance of rhythmicity and sleep disturbances as biomarkers of MD, both animal and clinical studies on the interaction of behavioural, neuroendocrine and sleep parameters may reveal molecular pathways that ultimately lead to the discovery of new

  1. Noachian-Age Silica Deposits on Mars with Features Resembling Modern Hot Spring Biosignatures at El Tatio, Chile

    Science.gov (United States)

    Ruff, S. W.; Farmer, J. D.

    2016-12-01

    Hydrothermal spring deposits of silica (sinter) have long been targets in the search for fossil life on Mars and early Earth because of their ability to capture and preserve biosignatures. In 2007, the Spirit rover observed exposures of opaline silica (amorphous SiO2-*nH2O) adjacent to "Home Plate" in the inner basin of the Columbia Hills of Gusev crater. The presence of opaline silica in the context of a succession of volcanic rocks is interpreted as evidence of past volcanic hydrothermal activity. The silica occurs most commonly in nodular masses that have a rubbly appearance but are considered outcrops because of their stratiform expression and resistance to deformation by the rover wheels. An origin via either fumarole-related acid-sulfate leaching or precipitation from hot spring fluids was suggested previously. However, the potential significance of the characteristic nodular and mm-scale digitate opaline silica structures was not recognized. Our new observations of silica sinter deposits from the active volcanic hydrothermal system at El Tatio in northern Chile provide a basis for scale-integrated comparisons to the silica features at Home Plate, including geologic context, mesoscale structures in outcrops, mm-scale textures, and spectral signatures. The physical environment of El Tatio presents a rare combination of high elevation ( 4300 m), low precipitation rate (Home Plate silica outcrops. Halite (NaCl) encrusts the silica at El Tatio yielding thermal infrared spectra that are the best match yet to spectra from Spirit. Furthermore, the nodular and digitate silica structures at El Tatio that most closely resemble those on Mars include complex sedimentary structures produced by a combination of biotic and abiotic processes. Although fully abiotic processes are not ruled out for the Martian silica structures, they satisfy an a priori definition of potential biosignatures.

  2. Stomach cancer incidence rates among Americans, Asian Americans and Native Asians from 1988 to 2011

    Yeerae Kim

    2015-02-01

    Full Text Available Stomach cancer is the second most common cancer in Eastern Asia, accounting for approximately 50% of all new cases of stomach cancer worldwide. Our objective was to compare the stomach cancer incidence rates of Asian Americans in Los Angeles with those of native Asians to assess the etiology of stomach cancer from 1988 to 2011. To examine these differences, Asian Americans (Korean, Japanese, Chinese, and Filipino Americans living in Los Angeles, California, USA and native Asians (from Korea, Japan, China, and the Philippines were selected for this study. Using the Cancer Incidence in Five Continents database, stomach cancer incidence rates were examined. Data from the National Cancer Registry of Korea were used for native Koreans. Between native countries, the incidence rates in Japan, China, the Philippines, and the US declined over time, but the incidence in Korea has remained constant. The incidences among Asian immigrants were lower than those among native Asians. The incidence rates of males were approximately 2 times higher than those among females in Asian countries were. The effect of immigration on stomach cancer incidence suggests that lifestyle factors are a significant determinant of stomach cancer risk. However, the incidence in Korea remains the highest of these countries

    The fetal weight estimation depends largely on the accuracy of abdominal circumference. The quality criteria are standardized to minimize variability and include visualization of the stomach. The objective of this study is to investigate the presence or absence of the stomach on the abdominal circumference for 3 different operators. We conducted re-reading of 204 ultrasound images in the second and third trimester of pregnancy, performed by three operators, at the maternity Port Royal in Paris in 2013. On these images, the presence of the stomach was sought and other quality criteria were verified. Among the 204 images, 166 included the stomach (81%). When studying for each of the three operators, there were 79%, 72% and 98% of the stomach into the abdominal circumference, a significant difference between operators (P=0.0029). Regarding the secondary criteria, the quality criteria found most often were the calipers and well placed ellipse (89%). According to the previous studies, the stomach seems to be a reference to search. Our study shows variability depending on the different operators. If a hierarchy of quality criteria is to be considered, the stomach does not seem to be the first criterion to search. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    We used high throughput pyrosequencing to characterize stomach and gut content microbiomes of Crassostrea virginica, the Easter oyster, obtained from two sites, one in Barataria Bay (Hackberry Bay) and the other in Terrebonne Bay (Lake Caillou), Louisiana, USA. Stomach microbiomes in oysters from Hackberry Bay were overwhelmingly dominated by Mollicutes most closely related to Mycoplasma; a more rich community dominated by Planctomyctes occurred in Lake Caillou oyster stomachs. Gut communities for oysters from both sites differed from stomach communities, and harbored a relatively diverse assemblage of phylotypes. Phylotypes most closely related to Shewanella and a Chloroflexi strain dominated the Lake Caillou and Hackberry Bay gut microbiota, respectively. While many members of the stomach and gut microbiomes appeared to be transients or opportunists, a putative core microbiome was identified based on phylotypes that occurred in all stomach or gut samples only. The putative core stomach microbiome comprised 5 OTUs in 3 phyla, while the putative core gut microbiome contained 44 OTUs in 12 phyla. These results collectively revealed novel microbial communities within the oyster digestive system, the functions of the oyster microbiome are largely unknown. A comparison of microbiomes from Louisiana oysters with bacterial communities reported for other marine invertebrates and fish indicated that molluscan microbiomes were more similar to each other than to microbiomes of polychaetes, decapods and fish.

    There is considerable information on the methylation of the promoter regions of different genes involved in gastric carcinogenesis. However, there is a lack of information on how this epigenetic process differs in tumors originating at different sites in the stomach. The aim of this study is to assess the methylation profiles of the MLH1, MGMT, and DAPK-1 genes in cancerous tissues from different stomach sites. Samples were acquired from 81 patients suffering stomach adenocarcinoma who underwent surgery for gastric cancer in the Lithuanian University of Health Sciences Hospital Kaunas Clinics in 2009-2012. Gene methylation was investigated with methylation-specific PCR. The study was approved by the Lithuanian Biomedical Research Ethics Committee. The frequencies of methylation in cancerous tissues from the upper, middle, and lower thirds of the stomach were 11.1, 23.1, and 45.4%, respectively, for MLH1; 22.2, 30.8, and 57.6%, respectively, for MGMT; and 44.4, 48.7, and 51.5%, respectively, for DAPK-1. MLH1 and MGMT methylation was observed more often in the lower third of the stomach than in the upper third (p stomach (coefficient, -0.48; p = 0.01). DAPK-1 and MLH1 methylation correlated inversely in tumors in the middle-third of the stomach (coefficient, -0.41; p = 0.01). Gene promoter methylation depends on the gastric tumor location.

    The stomach develops as the local widening of the foregut after Carnegie stage (CS) 13 that moves in a dramatic and dynamic manner during the embryonic period. Using the magnetic resonance images of 377 human embryos, we present the morphology, morphometry, and three-dimensional movement of the stomach during CS16 and CS23. The stomach morphology revealed stage-specific features. The angular incisura and the cardia were formed at CS18. The change in the angular incisura angle was approximately 90° during CS19 and CS20, and was stomach revealed that the stomach gradually becomes "deflected" during development. The stomach may appear to move to the left laterally and caudally due to its deflection and differential growth. The track of the reference points in the stomach may reflect the visual three-dimensional movement. The movement of point M, representing the movement of the greater curvature, was different from that of points C (cardia) and P (pyloric antrum). The P and C were located just around the midsagittal plane in all the stages observed. Point M moved in the caudal-left lateral direction until CS22. Moreover, the vector CP does not rotate around the dorsoventral axis, as widely believed, but around the transverse axis. The plane CPM rotated mainly around the longitudinal axis. The data obtained will be useful for prenatal diagnosis in the near future. Copyright © 2013 Wiley Periodicals, Inc.

    Stomach cancer mortality was prospectively studied among 9753 Japanese men and women who first responded to a mailed questionnaire in 1985 and were then followed through May 31, 1991. During this follow-up period, 57 stomach cancer deaths were identified. Current smokers had an increased risk of deaths from stomach cancer compared with never smokers (relative risk (RR) = 2.29, 95% confidence interval (CI): 1.15-4.56), but there was no dose-response to amount of cigarettes smoked. Daily alcohol drinkers who consumed 50 ml or more of alcohol per day also had a greater risk than nondrinkers (RR = 3.05, 95% CI: 1.35-6.91). There was no association between stomach cancer mortality and individual food consumption except a positive association with fruit intake. However, frequent use (greater than or equal to 3-4/week) of broiling of meats and traditional style Japanese salad preparation in their cooking procedures were positively associated with stomach cancer mortality. The RR values compared with infrequent use (less than or equal to 1-2/month) were 2.27 (95% CI: 1.06-4.85) and 3.10 (95% CI: 1.40-6.85), respectively. A positive family history of cancer, especially stomach cancer, significantly increased the risk of stomach cancer deaths (RR = 2.01, 95% CI: 1.12-3.63). The effects of these variables remained after adjustment for other variables.

    Stomach cancer is the second most common cancer in Eastern Asia, accounting for approximately 50% of all new cases of stomach cancer worldwide. Our objective was to compare the stomach cancer incidence rates of Asian Americans in Los Angeles with those of native Asians to assess the etiology of stomach cancer from 1988 to 2011. To examine these differences, Asian Americans (Korean, Japanese, Chinese, and Filipino Americans living in Los Angeles, California, USA) and native Asians (from Korea, Japan, China, and the Philippines) were selected for this study. Using the Cancer Incidence in Five Continents database, stomach cancer incidence rates were examined. Data from the National Cancer Registry of Korea were used for native Koreans. Between native countries, the incidence rates in Japan, China, the Philippines, and the US declined over time, but the incidence in Korea has remained constant. The incidences among Asian immigrants were lower than those among native Asians. The incidence rates of males were approximately 2 times higher than those among females in Asian countries were. The effect of immigration on stomach cancer incidence suggests that lifestyle factors are a significant determinant of stomach cancer risk. However, the incidence in Korea remains the highest of these countries.

    Atrophic gastritis, intestinal metaplasia, and Helicobacter pylori (H. pylori) infection are commonly recognized as the risk factor of gastric cancer. In Japan mass screening by the X-ray examination or endoscopy has been performed for a long time in general population or in work place because of the high death rate and high incidence of gastric cancer. Periodic endoscopy has been recommended for the subjects with atrophic gastritis and/or intestinal metaplasia to detect gastric cancer in early stage. On the other hand, there was no guideline to manage premalignant conditions such as atrophic gastritis, intestinal metaplasia, and dysplasia in foreign countries. Recently the guideline for the management of precancerous conditions and lesions in the stomach (MAPS) has been published by the combined efforts of the European Society of Gastrointestinal Endoscopy, European Helicobacter Study Group, European Society of Pathology, and the Sociedade Portuguesa de Endoscopia Digestiva. In this article the main statements have been discussed on comparing the understandings as the premalignant conditions in Japan.

  10. Resilience of honeybee colonies via common stomach: A model of self-regulation of foraging.

    Directory of Open Access Journals (Sweden)

    Thomas Schmickl

    Full Text Available We propose a new regulation mechanism based on the idea of the "common stomach" to explain several aspects of the resilience and homeostatic regulation of honeybee colonies. This mechanism exploits shared pools of substances (pollen, nectar, workers, brood that modulate recruitment, abandonment and allocation patterns at the colony-level and enable bees to perform several survival strategies to cope with difficult circumstances: Lack of proteins leads to reduced feeding of young brood, to early capping of old brood and to regaining of already spent proteins through brood cannibalism. We modeled this system by linear interaction terms and mass-action law. To test the predictive power of the model of this regulatory mechanism we compared our model predictions to experimental data of several studies. These comparisons show that the proposed regulation mechanism can explain a variety of colony level behaviors. Detailed analysis of the model revealed that these mechanisms could explain the resilience, stability and self-regulation observed in honeybee colonies. We found that manipulation of material flow and applying sudden perturbations to colony stocks are quickly compensated by a resulting counter-acting shift in task selection. Selective analysis of feedback loops allowed us to discriminate the importance of different feedback loops in self-regulation of honeybee colonies. We stress that a network of simple proximate mechanisms can explain significant colony-level abilities that can also be seen as ultimate reasoning of the evolutionary trajectory of honeybees.

    Purpose: To assess the dose–response relationship for stomach cancer after radiation therapy for cervical cancer. Methods and Materials: We conducted a nested, matched case–control study of 201 cases and 378 controls among 53,547 5-year survivors of cervical cancer diagnosed from 1943 to 1995, from 5 international, population-based cancer registries. We estimated individual radiation doses to the site of the stomach cancer for all cases and to corresponding sites for the matched controls (overall mean stomach tumor dose, 2.56 Gy, range 0.03-46.1 and after parallel opposed pelvic fields, 1.63 Gy, range 0.12-6.3). Results: More than 90% of women received radiation therapy, mostly with external beam therapy in combination with brachytherapy. Stomach cancer risk was nonsignificantly increased (odds ratio 1.27-2.28) for women receiving between 0.5 and 4.9 Gy to the stomach cancer site and significantly increased at doses ≥5 Gy (odds ratio 4.20, 95% confidence interval 1.41-13.4, P{sub trend}=.047) compared with nonirradiated women. A highly significant radiation dose–response relationship was evident when analyses were restricted to the 131 cases (251 controls) whose stomach cancer was located in the middle and lower portions of the stomach (P{sub trend}=.003), whereas there was no indication of increasing risk with increasing dose for 30 cases (57 controls) whose cancer was located in the upper stomach (P{sub trend}=.23). Conclusions: Our findings show for the first time a significant linear dose–response relationship for risk of stomach cancer in long-term survivors of cervical cancer.

    The aim of the real research was a study influence of leu-enkephalin and extracts from the leaves of goose-grass large, of burdock of felted and root of chicory on the motor function of stomach for dogs. The study was carried out on 6 outbred dogs-males, by mass 14-17 kg, with the fistula of stomach by Basov. A leu-enkephalin ("Vector", Russia) was entered intravenously in a dose 7 mcg/kg. The corresponding plant-based preparations entered perorally during 10-14 days to beginning of experiments, on an empty stomach, in a volume a no more than 20 ml. Experiments put in a morning clock, in 16-18 hours after eating, after the careful washing of stomach. For 30 mines to the record of motive activity of stomach an animal was enter a peptide or gave a corresponding extract as water or spirit infusion. At the choice of doses of vegetable preparations came from the before obtained data about the antiulcerous action of the used plants. The conduct of peptide rendered considerable stimulant influence on motor activity of stomach, that was expressed in the increase of period of work and increase of force of reductions especially tonic. All used plants preparations rendered modulating influence on motive activity of stomach. Changes consisted in strengthening of tonic and oppressing of phase component. The most considerable decline of amount of phase reductions caused application of extract of goose-grass. Not only an amount but also force of phase reductions diminished thus. An extract from the root of chicory less considerably reduced the arnount of Phase reJuctions, but here substantially increased their force. All used herbal medicines stimulated tonic activity. Thus, peptide and all studied herbal medicines stimulated motion activity of the stomach that could cause acceleration of evacuation of food to duodenum. Such effect should be considered while choosing the medicine for correction of stomach functional activity.

    Xeroderma pigmentosum group G (XPG) protein plays an important role in the DNA repair process by cutting the damaged DNA at the 3' terminus. Previous studies have indicated some polymorphisms in the XPG gene are associated with stomach cancer susceptibility. We performed this hospital-based case-control study to evaluate the association of four potentially functional XPG polymorphisms (rs2094258 C>T, rs751402 C>T, rs2296147 T>C and rs873601G>A) with stomach cancer susceptibility. The four single nucleotide polymorphisms (SNPs) were genotyped in 692 stomach cancer cases and 771 healthy controls. Logistic regression analysis was conducted, and odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the association of interest. Of the studied SNPs, XPG rs873601G>A polymorphism was found to significantly associate with stomach cancer susceptibility (AA versus OR = 1.31, 95% CI = 1.03-1.66, P = 0.027). Combined analysis of all SNPs revealed that the individuals with two of risk genotypes had a significantly increased stomach cancer risk (OR = 1.52, 95% CI = 1.13-2.06). In the stratification analysis, the association between the rs873601AA genotype and stomach cancer risk was observed in older group (>59 year), as well as patients with non-cardia stomach cancer. Further combined analysis indicated men, smokers, or non-drinkers more than one risk genotypes had a significantly increased stomach cancer risk. Our results indicate that XPG rs873601G>A polymorphism may be associated with the risk of stomach cancer. Further prospective studies with different ethnicities and large sample sizes are needed to validate our findings. © 2016 The Authors.

  16. Implications of Helicobacter pylori infection for stomach cancer prevention

    Directory of Open Access Journals (Sweden)

    Goodman Karen J.

    1997-01-01

    Full Text Available Accumulating evidence has implicated Helicobacter pylori, an established cause of chronic gastritis and peptic ulcer, in the etiology of gastric cancer. Control of this infection would reduce the occurrence of chronic gastritis and peptic ulcer and might substantially lower the risk of stomach cancer as well. The public health impact of this infectious agent warrants efforts to identify preventive measures. This paper reviews the evidence linking H. pylori infection to gastric cancer and evaluates the potential for control in high-risk populations. Current obstacles to H. pylori control are discussed, including the link to poor socioeconomic conditions, difficulty in identifying incident cases, lack of natural immunity to reinfection, limited effectiveness of antibiotic therapy in high-prevalence populations, and incomplete knowledge regarding the reservoir of infection, mode of transmission, host susceptibility factors, and the potential for developing an effective vaccine. Worthwhile avenues of research include studies designed to identify modifiable risk factors for acquisition of the infection, modifiable host factors that may increase resistance to chronic infection, more effective antibiotic therapies, and effective vaccines.

    The results of radiology and endoscopy were compared in 140 patients who had undergone gastric surgery for ulcer disease. Of 74 patients who were examined with single-contrast radiography, 37 had abnormalities that were demonstrated endoscopically. The radiographic sensitivities in these patients were: gastritis 2/22 (9%); ulcer 3/5 (60%); obstruction 8/8 (100%); and miscellaneous abnormalities 2/2 (100%). The predictive accuracy of a diagnois of ulcer was 38%. Of the 66 patients who were examined with double-contrast radiography, 33 abnormalities were found with endoscopy. The radiographic sensitivities were: gastritis 3/13 (23%); ulcer 7/10 (70%); obstruction 4/4 (100%); and miscellaneous abnormalities 6/6 (100%). The predictive accuracy of a diagnosis of ulcer was 44%. Radiology appears to be unreliable in diagnosing gastritis and recurrent ulceration in the post-operation stomach. The double-contrast technique does not offer significant improvement over the single-contrast method in evaluating these postoperative problems

    A 73-year-old man was referred to our hospital for further examination of a depressed lesion in the stomach found by cancer screening gastroscopy. A barium upper gastrointestinal series showed an area of irregular mucosa measuring 15 mm on the anterior wall of the gastric body. Esophagogastroduodenoscopy revealed a 15 mm depressed lesion on the anterior wall of the lower gastric body. We suspected an undifferentiated adenocarcinoma from the appearance and took some biopsies. However, histology of the specimens revealed amyloidal deposits in the submucosal layer without malignant findings. Congo red staining was positive for amyloidal protein and green birefringence was observed under polarized light microscopy. Congo red staining with prior potassium permanganate incubation confirmed the light chain (AL) amyloid type. There were no amyloid deposits in the colon or duodenum. Computed tomography of the chest, abdomen, and pelvis showed no remarkable findings. Thus, this case was diagnosed as a localized gastric amyloidosis characterized by AL type amyloid deposition in the mucosal or submucosal layer. As the clinical outcome of gastric AL amyloidosis seems favorable, this case is scheduled for periodic examination to recognize potential disease progression and has been stable for 2 years.

    Full Text Available Background: Worldwide, cancer of stomach is still the fourth common cancer and the second cause of mortality among all cancers affecting annually 870,000 subjects. This study aims to determine the frequency and the characteristics of gastric cancer in southern Iran. Materials and Methods: 10,800 of all cancers registered in Fars Hospital-based Cancer Registry were surveyed among which 574 cases were gastric cancer in both genders and all age groups. From January 2002 to December 2007, all hospital-based data were recorded according to International Classification of Disease for Oncology (ICD-O and registered cases included all invasive cancers in ICD-10 categories of C-00 to C-80 and all duplicate cases were eliminated. Results: Among all registered cancers, there were 574 cases of gastric cancer including 69.3% males. The mean age of patients was 58.1 ± 14.8 years, 25.4% with a history of in their first relatives and most of them were smokers (50.9% and from low socioeconomic class (45.5%. Metastasis was visible in 182 patients and majority of them underwent surgery (64.3%. The majority of gastric cancer patients were older than 50 years, smokers, low socioeconomic class, and female in favor of adenocarcinoma. Conclusion: Our results showed that in our area, treatment programs and health plans should focus on men, patients older than 50 years and with adenocarcinoma, smokers, and those in a low income level.

    Arterial supply to the stomach of dogs indigenous to Bangladesh was investigated by using latex. The hepatic, left gastric and splenic arteries sent their major branches to the stomach. The cranial and caudal branches of the left gastric artery supplied the lesser curvature of the stomach. The right gastric, and right and left gastroepiploic arteries also sent their branches to both the lesser and greater curvatures. Six or seven short gastric arteries from the splenic artery supplied the greater curvature. Anastomoses between the left and right gastric, between the left and right gastroepiploic, and between short gastric arteries and left gastric arteries were observed.

    Full Text Available It was fixed, that development of atophanum-carbacholimun ulcer of the gastroduodenal zone invoked various changes of secretory activity of the stomach. The changes directly depend on a progress of pathological process. As this takes place the reaction of stomach secretory glands varies under the stimulation with histamine: the decrease of stomach secretory glands’ work capacity till 10th day and its increase after 10–15th day were observed. Disorders of the glands’ ultradian rhythms at initial stages of modeling of gastrointestinal nervous regulation disturbances testify to dependence of periodic activity of gastrointestinal tract on resistance of regulatory mechanisms correlation.

    An x-ray picture of motor-evacuatory stomach function was studied in patients with pyloroduodenal ulcers after SPV with and without drainage (435 patients aged 16 to 80). Methods of investigation included polyprojectional radioscopy and panoramic and spot films at various time intervals after barium suspension intake. Stomach investigation was performed before operation as well as 2-3 weeks, 3-6 mos, 1-2 yrs, 3-5 yrs, and 7-10 yrs after it. Motor-evacuatory stomach function was studied over time. The least changes in motor-evacuatory fucntion were observed after SPV without drainage as a result of preserving pyloric contractility

    Cues of kinship are predicted to increase prosocial behavior due to the benefits of inclusive fitness, but to decrease approach motivation due to the potential costs of inbreeding. Previous studies have shown that facial resemblance, a putative cue of kinship, increases prosocial behavior. However, the effects of facial resemblance on mating preferences are equivocal, with some studies finding that facial resemblance decreases sexual attractiveness ratings, while other studies show that individuals choose mates partly on the basis of similarity. To further investigate this issue, a psychophysiological measure of affective processing, the startle response, was used in this study, assuming that differences in approach motivation to erotic pictures will modulate startle. Male volunteers (n = 30) viewed 30 pictures of erotic female nudes while startle eyeblink responses were elicited by acoustic noise probes. The female nude pictures were digitally altered so that the face either resembled the male participant or another participant, or were not altered. Non-nude neutral pictures were also included. Importantly, the digital alteration was undetected by the participants. Erotic pictures were rated as being pleasant and clearly reduced startle eyeblink magnitude as compared to neutral pictures. Participants showed greater startle inhibition to self-resembling than to other-resembling or non-manipulated female nude pictures, but subjective pleasure and arousal ratings did not differ among the three erotic picture categories. Our data suggest that visual facial resemblance of opposite-sex nudes increases approach motivation in men, and that this effect was not due to their conscious evaluation of the erotic stimuli.

    To investigate the approaches to improve therapeutic effect of stomach cancer by analysis of the long-term results of surgical treatment of this disease. Prognostic factors of stomach cancer were analyzed by Cox multivariate regression model based on clinical data of 2561 stomach cancer cases who underwent surgical treatment from 1964 to 2004 at Sun Yat-sen University Cancer Center. Survival rates were calculated by life table method. Gastrectomy was performed for 1950 cases with resectability of 76.1%, among which there were 1192 cases of curative resection (46.5%) and 758 cases of non-curative resection (29.6%). The other 611 cases of palliative operation included bypass procedures and laparotomy. Operative mortality of all cases was 0.8% and morbidity was 5.1%. For all cases the 1-, 3- and 5-year survival rate was 52.4%, 38.6% and 35.5%, respectively. The stage-specific 5-year survival rate was 86.8% (Stage I), 58.7% (Stage II), 28.4% (Stage III) and 7.6% (Stage IV), respectively. The 5-year survival after curative resection in the period of 40 years was 45.5%, and increased to 52.7% in the last two decades and 61.8% in recent decade. Stage-specific case proportion during the earlier two decades was 1.4% (Stage I), 10.6% (Stage II), 23.1% (Stage III) and 64.9% (Stage IV), respectively, and that during the recent two decades was 9.3%, 18.5%, 35.3% and 36.8%, respectively. The 5-year survival rate of cases during the earlier two decades was 18.0% and increased to 37.5% during the recent two decades. Multivariate analysis indicated that main prognostic factors of stomach cancer included TNM staging, curative resection and multidisciplinary treatment. Early detection and curative resection were the most important measures to improve therapeutic effect of stomach cancer. A surgery-predominant multidisciplinary treatment individualizing biological characteristics of tumor, staging of disease and tumor site will contribute to improvement of therapeutic effect of

    We developed a novel murine candidiasis model of the gastrointestinal tract using N-acetylglucosamine ( GlcNAc ) as a tool to aggravate symptoms. Forty-eight hours after intragastrically inoculating Candida albicans cells to immunosuppressed and GlcNAc-treated mice, vigorously accumulating patchy whitish plaques were observed on their inner stomach surface. Candida cells colonizing the plaques consisted of both yeast and mycelia, and were directly stained with Calcofluor White M2R. Aggravation of the candidiasis symptoms was dependent on GlcNAc concentration in drinking water, wherein administration of 50 mM GlcNAc not only severely worsened stomach symptoms, but also significantly increased Candida cell number in the stomach and small intestine. The aggravation effect of GlcNAc was enhanced by addition of sedative chemical chlorpromazine chloride after inoculation. In order to semi-quantitatively assess colonization by Candida in the stomach, we devised a new symptom scoring system that represents the extent of the patchy whitish plaques on the mucosal epithelium of the stomach. Histochemical analysis of Candida-infected tissues revealed not only a large amount of thick Candida mycelia invading mucosal epithelial stomach tissues but also infiltrating inflammatory cells. These results suggest that this murine gastrointestinal candidiasis model could serve as a useful tool for evaluating the protective activity of antifungal agents, probiotics, or functional foods against gastrointestinal candidiasis. Furthermore, from another point of view, this novel murine model could also be used to analyze the pathological mechanisms behind the translocation of C. albicans across intestinal barriers, which results in systemic Candida dissemination and infection.

    The purpose of the present study was to determine the response of the porcine coeliac-superior mesenteric ganglion complex (CSMG) neurons projecting to the prepyloric area of the porcine stomach to peripheral neuronal damage following partial stomach resection. To identify the sympathetic neurons innervating the studied area of stomach, the neuronal retrograde tracer Fast Blue (FB) was applied to control and partial stomach resection (RES) groups. On the 22nd day after FB injection, following laparotomy, the partial resection of the previously FB-injected stomach prepyloric area was performed in animals of RES group. On the 28th day, all animals were re-anaesthetized and euthanized. The CSMG complex was then collected and processed for double-labeling immunofluorescence. In control animals, retrograde-labelled perikarya were immunoreactive to tyrosine hydroxylase (TH), dopamine β-hydroxylase (DβH), neuropeptide Y (NPY) and galanin (GAL). Partial stomach resection decreased the numbers of FB-positive neurons immunopositive for TH and DβH. However, the strong increase of NPY and GAL expression, as well as de novo-synthesis of neuronal nitric oxide synthase (nNOS) and leu5-Enkephalin (LENK) was noted in studied neurons. Furthermore, FB-positive neurons in all pigs were surrounded by a network of cocaine- and amphetamine-regulated transcript peptide (CART)-, calcitonin gene-related peptide (CGRP)-, and substance P (SP)-, vasoactive intestinal peptide (VIP)-, LENK- and nNOS- immunoreactive nerve fibers. This may suggest neuroprotective contribution of these neurotransmitters in traumatic responses of sympathetic neurons to peripheral axonal damage. Copyright © 2015 Elsevier B.V.

    Full Text Available OBJECTIVE: To compare the clinical features of a familial prion disease with those of frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17. BACKGROUND: Prion diseases are not usually considered in the differential diagnosis of FTDP-17, since familial Creutzfeldt-Jakob disease (CJD, the most common inherited prion disease, often manifests as a rapidly progressive dementia. Conversely, FTDP-17 usually has an insidious onset in the fifth decade, with abnormal behavior and parkinsonian features. METHOD: We present the clinical features of 12 patients from a family with CJD associated with a point mutation at codon 183 of the prion protein gene. RESULTS: The mean age at onset was 44.0 ± 3.7; the duration of the symptoms until death ranged from two to nine years. Behavioral disturbances were the predominant presenting symptoms. Nine patients were first seen by psychiatrists. Eight patients manifested parkinsonian signs. CONCLUSION: These clinical features bear a considerable resemblance to those described in FTDP-17.

    The general view in psychological science is that natural categories obey a coherent, family-resemblance principle. In this investigation, we documented an example of an important exception to this principle: Results of a multidimensional-scaling study of igneous, metamorphic, and sedimentary rocks (Experiment 1) suggested that the structure of these categories is disorganized and dispersed. This finding motivated us to explore what might be the optimal procedures for teaching dispersed categories, a goal that is likely critical to science education in general. Subjects in Experiment 2 learned to classify pictures of rocks into compact or dispersed high-level categories. One group learned the categories through focused high-level training, whereas a second group was required to simultaneously learn classifications at a subtype level. Although high-level training led to enhanced performance when the categories were compact, subtype training was better when the categories were dispersed. We provide an interpretation of the results in terms of an exemplar-memory model of category learning.

    Full Text Available Background. Extramedullary hematopoiesis is most often seen in reticuloendothelial organs specially spleen, liver, or lymph nodes, and it is rarely seen in lung parenchyma. Almost all reported cases of pulmonary extramedullary hematopoiesis occurred following myeloproliferative disorders specially myelofibrosis. Other less common underlying causes are thalassemia syndromes and other hemoglobinopathies. There was not any reported case of pulmonary extramedullary hematopoiesis in asthmatic patients in the medical literature. Case. Here we reported a 65-year-old lady who was a known case of bronchial asthma with recent developed right lower lobe lung mass. Chest X-ray and CT studies showed an infiltrating mass resembling malignancy. Fine needle aspiration cytology of mass revealed pulmonary extramedullary hematopoiesis. The patient followed for 10 months with serial physical examination and laboratory evaluations which were unremarkable. Conclusion. Extramedullary hematopoiesis of lung parenchyma can be mistaken for lung cancer radiologically. Although previous reported cases occurred with myelofibrosis or hemoglobinopathies, we are reporting the first case of asthma-associated extramedullary hematopoiesis.

    Since the terrorist attacks on the U.S. on September 11th, 2001, Nuclear Security has been focused on and treated as a global issue in the international community and it has also been discussed as a real and serious threat to nuclear power plants in the world since 'The Great East Japan Earthquake' in March, 2011. The International Atomic Energy Agency (IAEA) issued a document including Nuclear Security Recommendations (INFCIRC/225/Rev.5) (NSS 13) in the Nuclear Security Series and emphasized the necessity of fostering Nuclear Security Culture. Nuclear Security Culture has been frequently discussed at various kinds of seminars and events. Since the officials in charge of Nuclear Security are familiar with the area of Nuclear Safety, the relationships between Nuclear Safety Culture and Nuclear Security Culture have been the point in controversy. This paper clarifies relevance between Nuclear Safety and Security, considers resemblances and differences of their concepts and lessons learned for each culture from nuclear power plant accidents, and promotes deeper understanding of Nuclear Safety and Nuclear Security Culture.

    Granular cell ameloblastoma is classified as a histological subtype of solid/multicystic ameloblastoma. Usual granular cell ameloblastoma is histologically characterized by granular changes of stellate-like cells located in the inner portion of the epithelial follicles. Here we report a case of another type of granular cell ameloblastoma, showing predominant anastomosing double-stranded trabeculae of granular cells. This type of granular cell ameloblastoma is extremely rare, and the World Health Organization classification does not contain the entity. We tentatively termed it 'anastomosing granular cell ameloblastoma' in this report. The present case suggests the importance of differential diagnosis because the histology of 'anastomosing granular cell ameloblastoma' resembles that of salivary gland oncocytoma rather than that of usual granular cell ameloblastoma. The trabeculae observed in our case continued to the peripheral cells of a small amount of epithelial sheets of plexiform ameloblastoma, and the tumor cells were positive for CK19, which is regarded as an immunohistochemical marker of odontogenic epithelium. Similar to usual granular cell ameloblastoma, the tumor cells had CD68-positive granules. For precise diagnosis of this condition, immunohistochemistry using CK19 and CD68, as well as detailed histological observation, are recommended. © 2014 Japanese Society of Pathology and Wiley Publishing Asia Pty Ltd.

    Nonlinear kinetic waves of the KEEN type [1] but constructed with two BGK recipes are tested with 1D Vlasov-Poisson simulation (1DVPS). One is that of Allis [2] as modified by Johnston (unpublished), the other is that of Eliasson and Shukla [3]. Strong kinetic waves survive well, but not weaker ones. The potential wave trains resemble those from the Korteweg-deVries equation. This proves to be natural when charge density variation with electrostatic potential is like a quadratic polynomial. For expositions on the physics of ponderomotively driven KEEN waves, consult presentations by Afeyan and Savchenko, this conference.

    Full Text Available Abstract Background An unusual sequence of post operative events heralded by hemodynamic deterioration followed by dyspnea and rapidly progressive dilatation of superficial neck and facial veins, resembling a superior vena cava syndrome, two days post surgical resection of filamentous aortic valve masses, closure of a patent foramen ovale, and performance of a modified Maze procedure for atrial fibrillation in a patient that presented with transient neurologic findings is presented. Case Presentation Although both clinical findings and hemodynamic derangements completely resolved following tricuspid valve repair aimed to correct the new onset severe tricuspid regurgitation noted post operatively; a clear mechanism was not readily obvious and diagnostic testing data somewhat conflictive. We present a careful retrospective examination of all clinical data and review possible clinical entities that could have been implicated in this particular case and recognize that transesophageal echocardiographic findings were most useful in identifying the best course of action. Conclusion After reviewing all clinical data and despite the inconclusive nature of test results; the retrospective examination of transesophageal echocardiographic findings proved to be most useful in identifying the best course of action. We postulate that in our case, resolution of the suspected pulmonary embolism with anticoagulation and reestablishment of a normal right ventricular geometry with tricuspid valve repair worked in unison in restoring normal hemodynamics and resolving both dyspnea and venous dilatation.

    Four Regional Health Protection Branch laboratories each compared aerobic colony counts obtained after "stomaching" and blending, for a minimum of 10 samples in each of the seven food groups: dry pastas; chocolate and cocoa powders; frozen entrees (macaroni and cheese, chow mein, chop suey, fried rice, seafood casseroles, and Salisbury steak); nonfat dry milk; shrimp and crabmeats; spices; and breakfast sausages. Overall, counts obtained after using the Stomacher were equivalent to or higher than counts obtained after using the blender in 73% of the comparisons (alpha = 0.05). Where differences existed, counts obtained after using the Stomacher tended to be higher than counts obtained after using the blender from milk powder and lower from sausage. Aerobic colony counts from these foods are not unacceptably biased when obtained by Stomacher.

    The paper presents a method for analysis of stomach folds pattern in abdominal X-ray CT images. Many stomach cancers have local concentration of folds at cancer lesions. Therefore, in stomach diagnosis, it is very important to evaluate quantitatively such fold concentration. In this paper, a method for calculation of concentration index for line figure on a curved surface is proposed first. Then, using this method a processing procedure for detection of stomach cancer from an abdominal X-ray CT image is developed. In the experiment using practical X-ray CT images, it is shown that by the proposed procedure, higher values of concentration index are obtained at cancer area. (author)

    The probability of a North Sea whiting Merlangius merlangus stomach containing fresh food was depressed when partially digested food was already present in the stomach. The lowered probability was detected even at levels where the fish was physiologically able to ingest an average meal. The feeding...... probability of c. 15% of the fish caught was predicted to be severely decreased at the level of partially digested food found in the stomachs. No effect of stomach fullness on meal size was found. indicating that the saturation is affecting search activity rather than prey or meal size selection. The diurnal...... pattern in food intake varied between the five sampling locations, presumably Lis a result of differences in prey availability. (C) 2002 The Fisheries Society of the British Isles.

    Full Text Available Heterotopic pancreatic tissue of the stomach is a rare condition. Gastric diverticulum is also a rare condition, mostly located at the fornix. Therefore, the existence of a pyloric gastric diverticulum containing a submucosal tumor proved to be heterotopic pancreatic tissue of the stomach is an extremely rare condition. The patient was a young thin male with epigastralgia chronically treated for gastritis/ulcer. Following an episode of melena, he underwent gastroscopy that diagnosed antral gastric diverticulum containing a polyp. The lesion was surgically removed. The pathology report stated: heterotopic pancreatic tissue of the stomach with secondary development of a traction diverticulum. Heterotopic pancreas tissue of the stomach is a rare condition but the association with gastric diverticulum is completely unusual. The possibility of the ectopic tissue leading to secondary diverticulum development should be considered.

    One of complications associated with long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) is peptic ulcer. Recently, we found that orally administered phosphatidic acid (PA) ameliorated aspirin-induced stomach lesions in mice. In this study, we identified PA-rich food sources and examined the effects of the food materials on indomethacin-induced stomach ulcer. Among examined, buckwheat (Fagopyrum esculentum) bran contained the highest level of PA (188 mg/100 g). PA was the richest phospholipid (25%) in the lipid fraction of the buckwheat bran. Administration of the lipid extracts of buckwheat bran significantly ameliorated indomethacin-induced stomach lesions in mice. In contrast, wheat (Triticum durum) bran lipids (PA, 4%) and soybean (Glycine max) lipids (PA, 3%) were not associated with ameliorative effects. These results indicated that PA-rich lipids can be used as an effective supplement for prevention of NSAID-induced stomach ulcer.

    Gastroesophageal reflux is associated with numerous pathologic conditions of the upper aerodigestive tract. Gastric pepsin within reflux contributes to immunologic reactions in the tonsil. In this study, we aimed to find the relationships between pepsin and tonsillar hypertrophy. We explored the notion whether tonsillar hypertrophy was due to pepsin-mediated gastric reflux in tonsil hypertrophy. Fifty-four children with tonsil hypertrophy and 30 adults with tonsillitis were recruited before surgical treatment. Blood and tonsil tissues from each patient were harvested for analysis of changes in lymphocyte and macrophage numbers coupled with histological and biochemical analysis. Pepsin was expressed at different levels in tonsil tissues from each tonsillar hypertrophy. Pepsin-positive cells were found in the crypt epithelium, surrounding the lymphoid follicle with developing fibrosis, and also surrounding the lymphoid follicle that faced the crypt. And also, pepsin staining was well correlated with damaged tonsillar squamous epithelium and TGF-β1 and iNOS expression in the tonsil section. In addition, pepsin and TGF-β1-positive cells were co-localized with CD68-positive cells in the crypt and surrounding germinal centers. In comparison of macrophage responsiveness to pepsin, peripheral blood mononuclear cells (PBMNCs) were noticeably larger in the presence of activated pepsin in the child group. Furthermore, CD11c and CD163-positive cells were significantly increased by activated pepsin. However, this was not seen for the culture of PBMNCs from the adult group. The lymphocytes and monocytes are in a highly proliferative state in the tonsillar hypertrophy and associated with increased expression of pro-inflammatory factors as a result of exposure to stomach reflux pepsin.

    Tissues of cancerous and corresponding normal stomach were studied by FTIR technique. The results showed that there are obvious differences between FTIR spectra of them in spectral parameters such as frequency, intensity and band shape etc. The changes involving the phosphate symmetric stretching nu s, PO2- and asymmetric stretching nu as, PO2- modes, the CH3 and CH2 groups stretching (nu s, CH2, nu as, CH3) and bending (delta CH2) modes and the C-O stretching nu C-O mode were discussed. In addition, the changes of structure of hydrogen-bonding of nucleic acid and cell proteins and the packing and the conformational structure of the membrance lipids were analysed further. The average wavenumber of band of nu s, PO2- shifted from 1,080.92 cm-1 to 1,085.93 cm-1 and that of nu as, PO2- shifted from 1,239.64 cm-1 to 1,238.73 cm-1 which indicated that the degree of hydrogen-bonding formed by oxygen atom of the phosphodiester groups of nucleic acids was increased. The average wavenumber of band of delta CH2 of membrance lipids shifted from 1,455.23 cm-1 to 1,457.37 cm-1 that suggested that the conformational structure of the methylene chains of membrance lipids is more disordered than in normal tissues. The shift of band of nu C-O of cell proteins from 1,166.08 cm-1 to 1,166.58 cm-1 indicated that the hydrogen-bond of cell proteins become weaker.

    Intramural gastric masses arise in the wall of the stomach (generally within the submucosa or muscularis propria), often with intact overlying mucosa. These tumors are typically mesenchymal in origin and have overlapping radiologic appearances. A combination of features such as location, attenuation, enhancement, and growth pattern may suggest one diagnosis over another. Gastrointestinal stromal tumors (GISTs) account for the majority of intramural tumors and can vary widely in appearance, from small intraluminal lesions to exophytic masses that protrude into the peritoneal cavity, commonly with areas of hemorrhage or necrosis. A well-circumscribed mass measuring −70 to −120 HU is a lipoma. Leiomyomas usually manifest as low-attenuation masses at the gastric cardia. Homogeneous attenuation is a noteworthy characteristic of schwannomas, particularly for larger lesions that might otherwise be mistaken for GISTs. A hypervascular mass in the antrum is a common manifestation of glomus tumors. Hemangiomas are also hypervascular but often manifest in childhood. Inflammatory fibroid polyps usually arise as a polypoid mass in the antrum. Inflammatory myofibroblastic tumors are infiltrative neoplasms with a propensity for local recurrence. Plexiform fibromyxomas are rare, usually antral tumors. Carcinoid tumors are epithelial in origin, but often submucosal in location, and therefore should be distinguished from other intramural lesions. Multiple carcinoid tumors are associated with hypergastrinemia, either in the setting of chronic atrophic gastritis or Zollinger-Ellison syndrome. Sporadic solitary carcinoid tumors not associated with hypergastrinemia have a higher rate of metastasis. Histopathologic analysis, including immunohistochemistry, is usually required for diagnosis of intramural masses. © RSNA, 2013 PMID:24108557

    The glands of the stomach body and antral mucosa contain a complex compendium of cell lineages. In lower mammals, the distribution of oxyntic glands and antral glands define the anatomical regions within the stomach. We examined in detail the distribution of the full range of cell lineages within the human stomach. We determined the distribution of gastric gland cell lineages with specific immunocytochemical markers in entire stomach specimens from three non-obese organ donors. The anatomical body and antrum of the human stomach were defined by the presence of ghrelin and gastrin cells, respectively. Concentrations of somatostatin cells were observed in the proximal stomach. Parietal cells were seen in all glands of the body of the stomach as well as in over 50% of antral glands. MIST1 expressing chief cells were predominantly observed in the body although individual glands of the antrum also showed MIST1 expressing chief cells. While classically described antral glands were observed with gastrin cells and deep antral mucous cells without any parietal cells, we also observed a substantial population of mixed type glands containing both parietal cells and G cells throughout the antrum. Enteroendocrine cells show distinct patterns of localisation in the human stomach. The existence of antral glands with mixed cell lineages indicates that human antral glands may be functionally chimeric with glands assembled from multiple distinct stem cell populations.

  16. Control of stomach smooth muscle development and intestinal rotation by transcription factor BARX1.

    Science.gov (United States)

    Jayewickreme, Chenura D; Shivdasani, Ramesh A

    2015-09-01

    Diverse functions of the homeodomain transcription factor BARX1 include Wnt-dependent, non-cell autonomous specification of the stomach epithelium, tracheo-bronchial septation, and Wnt-independent expansion of the spleen primordium. Tight spatio-temporal regulation of Barx1 levels in the mesentery and stomach mesenchyme suggests additional roles. To determine these functions, we forced constitutive BARX1 expression in the Bapx1 expression domain, which includes the mesentery and intestinal mesenchyme, and also examined Barx1(-/)(-) embryos in further detail. Transgenic embryos invariably showed intestinal truncation and malrotation, in part reflecting abnormal left-right patterning. Ectopic BARX1 expression did not affect intestinal epithelium, but intestinal smooth muscle developed with features typical of the stomach wall. BARX1, which is normally restricted to the developing stomach, drives robust smooth muscle expansion in this organ by promoting proliferation of myogenic progenitors at the expense of other sub-epithelial cells. Undifferentiated embryonic stomach and intestinal mesenchyme showed modest differences in mRNA expression and BARX1 was sufficient to induce much of the stomach profile in intestinal cells. However, limited binding at cis-regulatory sites implies that BARX1 may act principally through other transcription factors. Genes expressed ectopically in BARX1(+) intestinal mesenchyme and reduced in Barx1(-/-) stomach mesenchyme include Isl1, Pitx1, Six2 and Pitx2, transcription factors known to control left-right patterning and influence smooth muscle development. The sum of evidence suggests that potent BARX1 functions in intestinal rotation and stomach myogenesis occur through this small group of intermediary transcription factors.

    Noguchi, Taka-Aki K; Kurisaki, Akira

    2017-01-01

    In this chapter, we describe a method for the induction of stomach organoids from mouse embryonic stem (ES) cells. We used an embryoid body-based differentiation method to induce gastric primordial epithelium covered with mesenchyme and further differentiate it in Matrigel by 3D culture. The differentiated organoid contains both corpus- and antrum-specific mature gastric tissue cells. This protocol may be useful for a variety of studies in developmental biology and disease modeling of the stomach.

    Although several experimental studies suggested that soy isoflavone intake inhibits the growth of stomach cancer, previous epidemiological studies have observed inconsistent results. We evaluated the associations of soy or isoflavone intake with stomach cancer incidence after considering several lifestyle factors, including salt intake, in a population-based prospective cohort study in Japan. Subjects were 14,219 men and 16,573 women aged 35 years or older in September 1992. Soy and isoflavone intakes, assessed with a validated food-frequency questionnaire, were controlled for the total energy intake. Cancer incidence was mainly confirmed through regional population-based cancer registries. Until March 2008, 441 men and 237 women developed stomach cancer. After adjustments for multiple confounders, a significantly decreased relative risk of stomach cancer was observed in the highest vs. lowest quartile of soy intake; the estimated hazard ratios were 0.71 (95% CI: 0.53, 0.96) for men (p for trend = 0.039) and 0.58 (95% CI: 0.36, 0.94) for women (p for trend = 0.003). Similar inverse associations between isoflavone intake and stomach cancer risk were also observed in women. Higher intake of non-fermented soy foods was significantly associated with a lower risk of stomach cancer (p for trend: 0.022 in men and 0.005 in women), whereas there was no significant association between the intake of fermented soy foods and a risk of stomach cancer. These results suggest that a high intake of soy isoflavone, mainly nonfermented soy foods, have a protective effect against stomach cancer. © 2015 UICC.

    Family history and nutritional status may affect the long-term prognosis of stomach cancer, but evidence is insufficient and inconsistent. To clarify the prognostic factors of stomach cancer, we conducted a prospective study of 1,033 Japanese patients with histologically confirmed stomach cancer who were admitted to a single hospital between 1997 and 2005. Family history of stomach cancer and pretreatment body mass index (BMI) were assessed using a self-administered questionnaire. Clinical data were retrieved from a hospital-based cancer registry. All patients were completely followed up until December, 2008. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated according to family history in parents and siblings and BMI category. During a median follow-up of 5.3 years, 403 all-cause and 279 stomach cancer deaths were documented. Although no association with family history was observed in the patients overall, analysis according to age group found an increased risk of all-cause death associated with a history in first degree relatives (HR = 1.61, 95% CI: 0.93-2.78, p = 0.09) and with a parental history (HR = 1.86, 95% CI: 1.06-3.26) among patients aged under 60 years at diagnosis. BMI was related to all-cause and stomach cancer death among patients aged 60 and over, showing a J-shaped pattern (HR of all-cause death = 2.28 for BMI stomach cancer, especially parental history, may affect mortality among younger stomach cancer patients, whereas nutritional status may be a prognostic factor in older patients. © 2014 UICC.

    Sex differences in stress-related diseases such as stroke and stomach cancer are well established, but the mechanisms underlying this phenomenon remain unknown. Despite the fact that sexual hormones play an important role in the high resistance of females to harmful effects of stress compared with males, the regulation of oxygenation status can be a potential factor, which might explain sex differences in stress-induced cerebrovascular catastrophes in newborn rats and in mutagens activation in adult rats with stomach cancer.

    Stomach and intestines are involved in the secretion of gastrointestinal fluids and the absorption of nutrients and fluids, which ensure normal gut functions. Aquaporin water channels (AQPs) represent a major transcellular route for water transport in the gastrointestinal tract. Until now, at least 11 AQPs (AQP1-11) have been found to be present in the stomach, small and large intestines. These AQPs are distributed in different cell types in the stomach and intestines, including gastric epithelial cells, gastric glands cells, absorptive epithelial cells (enterocytes), goblet cells and Paneth cells. AQP1 is abundantly distributed in the endothelial cells of the gastrointestinal tract. AQP3 and AQP4 are mainly distributed in the basolateral membrane of epithelial cells in the stomach and intestines. AQP7, AQP8, AQP10 and AQP11 are distributed in the apical of enterocytes in the small and large intestines. Although AQP-null mice displayed almost no phenotypes in gastrointestinal tracts, the alterations of the expression and localization of these AQPs have been shown to be associated with the pathology of gastrointestinal disorders, which suggests that AQPs play important roles serving as potential therapeutic targets. Therefore, this review provides an overview of the expression, localization and distribution of AQPs in the stomach, small and large intestine of human and animals. Furthermore, this review emphasizes the potential roles of AQPs in the physiology and pathophysiology of stomach and intestines.

    Background and aims Atrophic gastritis (AG) results most often from Helicobacter pylori (H. pylori) infection. AG is the most important single risk condition for gastric cancer that often leads to an acid-free or hypochlorhydric stomach. In the present paper, we suggest a rationale for noninvasive screening of AG with stomach-specific biomarkers. Methods The paper summarizes a set of data on application of the biomarkers and describes how the test results could be interpreted in practice. Results In AG of the gastric corpus and fundus, the plasma levels of pepsinogen I and/or the pepsinogen I/pepsinogen II ratio are always low. The fasting level of gastrin-17 is high in AG limited to the corpus and fundus, but low or non-elevated if the AG occurs in both antrum and corpus. A low fasting level of G-17 is a sign of antral AG or indicates high intragastric acidity. Differentiation between antral AG and high intragastric acidity can be done by assaying the plasma G-17 before and after protein stimulation, or before and after administration of the proton pump inhibitors (PPI). Amidated G-17 will rise if the antral mucosa is normal in structure. H. pylori antibodies are a reliable indicator of helicobacter infection, even in patients with AG and hypochlorhydria. Conclusions Stomach-specific biomarkers provide information about the stomach health and about the function of stomach mucosa and are a noninvasive tool for diagnosis and screening of AG and acid-free stomach.

    It is known that the stomach is colonized by indigenous lactobacilli in mice. The aim of this study was to examine the role of such lactobacilli in the development of the stomach. For a DNA microarray analysis, germ-free BALB/c mice were orally inoculated with 109 CFU lactobacilli, and their stomachs were excised after 10 days to extract RNA. As a result, lactobacillus-associated gnotobiotic mice showed dramatically decreased expression of the gastrin gene in comparison to germ-free mice. The mean of the log2 fold change in the gastrin gene was −4.3. Immunohistochemistry also demonstrated the number of gastrin-positive (gastrin+) cells to be significantly lower in the lactobacillus-associated gnotobiotic mice than in the germ-free mice. However, there was no significant difference in the number of somatostatin+ cells in these groups of mice. Consequently, gastric acid secretion also decreased in the mice colonized by lactobacilli. In addition, an increase in the expression of the genes related to muscle system development, such as nebulin and troponin genes, was observed in lactobacillus-associated mice. Moreover, infection of germ-free mice with Helicobacter pylori also showed the down- and upregulation of gastrin and muscle genes, respectively, in the stomach. These results thus suggested that indigenous lactobacilli in the stomach significantly affect the regulation of gastrin-mediated gastric acid secretion without affecting somatostatin secretion in mice, while H. pylori also exerts such an effect on the stomach.

    We sought to determine the relationship between the degree of stomach herniation by antenatal sonography and neonatal outcomes in fetuses with isolated left-sided congenital diaphragmatic hernia (CDH). We retrospectively reviewed neonatal medical records and antenatal sonography of fetuses with isolated left CDH cared for at a single institution (2000-2012). Fetal stomach position was classified on sonography as follows: intra-abdominal, anterior left chest, mid-to-posterior left chest, or retrocardiac (right chest). Ninety fetuses were included with 70% surviving to neonatal discharge. Stomach position was intra-abdominal in 14% (n = 13), anterior left chest in 19% (n = 17), mid-to-posterior left chest in 41% (n = 37), and retrocardiac in 26% (n = 23). Increasingly abnormal stomach position was linearly associated with an increased odds of death (OR 4.8, 95% CI 2.1-10.9), extracorporeal membrane oxygenation (ECMO; OR 5.6, 95% CI 1.9-16.7), nonprimary diaphragmatic repair (OR 2.7, 95% CI 1.4-5.5), prolonged mechanical ventilation (OR 5.9, 95% CI 2.3-15.6), and prolonged respiratory support (OR 4.0, 95% CI 1.6-9.9). All fetuses with intra-abdominal stomach position survived without substantial respiratory morbidity or need for ECMO. Fetal stomach position is strongly associated with neonatal outcomes in isolated left CDH. This objective tool may allow for accurate prognostication in a variety of clinical settings. © 2015 S.

    Gastric acidity is likely a key factor shaping the diversity and composition of microbial communities found in the vertebrate gut. We conducted a systematic review to test the hypothesis that a key role of the vertebrate stomach is to maintain the gut microbial community by filtering out novel microbial taxa before they pass into the intestines. We propose that species feeding either on carrion or on organisms that are close phylogenetic relatives should require the most restrictive filter (measured as high stomach acidity) as protection from foreign microbes. Conversely, species feeding on a lower trophic level or on food that is distantly related to them (e.g. herbivores) should require the least restrictive filter, as the risk of pathogen exposure is lower. Comparisons of stomach acidity across trophic groups in mammal and bird taxa show that scavengers and carnivores have significantly higher stomach acidities compared to herbivores or carnivores feeding on phylogenetically distant prey such as insects or fish. In addition, we find when stomach acidity varies within species either naturally (with age) or in treatments such as bariatric surgery, the effects on gut bacterial pathogens and communities are in line with our hypothesis that the stomach acts as an ecological filter. Together these results highlight the importance of including measurements of gastric pH when investigating gut microbial dynamics within and across species.

    Understanding the lymphatic drainage route in gastric cancer is crucial for complete lymph node retrieval from sites susceptible to metastasis. However, the lymphatic stream of the stomach is complex and remains incompletely characterized. Patients with small (cancer with solitary lymph node metastasis treated at the Cancer Institute Hospital were included in this study. A total of 135 patients were classified according to the location of the solitary lymph node metastasis into the left gastric artery (LGA) group, the right gastroepiploic artery (RGEA) group, the right gastric artery (RGA) group, or the splenic artery (SA) group. The location of the primary tumors was investigated to aid the mapping of the lymphatic stream of the stomach. Lymphatic flow in LGA (65 patients) and in RGEA (57 patients) are main lymphatic drainage routes of the stomach. The lymphatic area overlapped in the lower third of the stomach in LGA and RGEA, and the lymphatic flow associated with gastric cancer located within this overlapped area can be multidirectional. Skip metastases were observed in 13 patients (10%), and all skip metastases were observed in the suprapancreatic area (station 7, 8a, 9, or 11p). The lymphatic stream of the stomach is complicated and multidirectional. Understanding and mapping the complex lymphatic streams of the stomach will allow surgeons to perform more effective lymph node dissection during gastric cancer surgery.

    The relationship between asbestos and stomach cancer is not well understood because of small number of cases. This study aimed to determine the incidence and mortality of stomach cancer among workers exposed to asbestos based on a systematic review and meta-analysis approach. Relevant English electronic databases were systematically searched for published studies characterizing the risk of developing stomach cancer as a result of asbestos exposure. Standardized mortality rate (SMR) for stomach cancer with its 95% confidence interval (CI) was pooled using a fixed-/random-effect model in STATA. A total of 32 independent studies were included for the analysis. The overall SMR for stomach cancer was 1.19 (95% CI 1.06-1.34), with a moderate degree of heterogeneity across the studies (I(2) = 37.6%, P = 0.011). Being male, exposure to crocidolite, miners, studies conducted in Europe and Oceania, and long study follow-up (≥ 25 years) all contribute to significantly higher SMR. Significant publication bias was observed. Elevated risk of stomach cancer mortality was evidenced among workers exposed to crocidolite, especially male miners.

    There are strong indications for a causal association between areca-nut consumption and cancers. In Meghalaya, India, the variety of areca-nut is used as raw and unprocessed form whose chemical composition and pharmacological actions have been reported. Yet we know little on the initial pathway involved in areca-nut associated carcinogenesis since it is difficult to assess its effects on genetic alterations without interference of other compounding factors. Therefore, present study was undertaken in mice to verify the ability of raw areca-nut (RAN) to induce cancer and to monitor the expression of certain genes involved in carcinogenesis. This study was not intended to isolate any active ingredients from the RAN and to look its action. Three groups of mice (n = 25 in each) were taken and used at different time-points for different experimental analysis. The other three groups of mice (n = 15 in each) were considered for tumor induction studies. In each set, two groups were administered RAN-extract ad libitum in drinking water with or without lime. The expression of certain genes was assessed by conventional RT-PCR and immunoblotting. The mice were given the whole RAN-extract with and without lime in order to mimic the human consumption style of RAN. Histological preparation of stomach tissue revealed that RAN induced stomach cancer. A gradual increase in the frequency of precocious anaphase and aneuploid cells was observed in the bone marrow cells with a greater increment following RAN + lime administeration. Levels of p53, Bax, Securin and p65 in esophageal and stomach cells were elevated during early days of RAN exposure while those of different mitotic checkpoint proteins were downregulated. Apoptotic cell death was detected in non-cancerous stomach cells but not in tumor cells which showed overexpression of Bax and absence of PARP. Present study suggested (a) RAN induces stomach cancer, however, presence of lime promoted higher cell transformation and thereby

    Survival is a key component of fitness. Species that occupy discrete breeding colonies with different characteristics are often exposed to varying costs and benefits associated with group size or environmental conditions, and survival is an integrative net measure of these effects. We investigated the extent to which survival probability of adult (≥1-year old) cliff swallows (Petrochelidon pyrrhonota) occupying different colonies resembled that of their parental cohort and thus whether the natal colony had long-term effects on individuals. Individuals were cross-fostered between colonies soon after hatching and their presence as breeders monitored at colonies in the western Nebraska study area for the subsequent decade. Colony-specific adult survival probabilities of offspring born and reared in the same colony, and those cross-fostered away from their natal colony soon after birth, were positively and significantly related to subsequent adult survival of the parental cohort from the natal colony. This result held when controlling for the effect of natal colony size and the age composition of the parental cohort. In contrast, colony-specific adult survival of offspring cross-fostered to a site was unrelated to that of their foster parent cohort or to the cohort of non-fostered offspring with whom they were reared. Adult survival at a colony varied inversely with fecundity, as measured by mean brood size, providing evidence for a survival–fecundity trade-off in this species. The results suggest some heritable variation in adult survival, likely maintained by negative correlations between fitness components. The study provides additional evidence that colonies represent non-random collections of individuals.

    Full Text Available In today’s world, people from different countries, cities and institutions unprecedentedly resemble each other in every aspect of life. Likewise, the deeds and imagery aspirations of Oriental and Occidental people also resemble. In such an atmosphere, the local cultures rooted in history become accessories and lose their historical significance and metaphysical aspects in the edifice of the society. This study aims to analyze Prophet Muhammad’s (s.a.w. warning, “Who so imitates other people becomes one of them”, its layers of meaning and its relationship with “image and global resemblence”.

    Methylentetrahydrofolate reductase plays a central role in converting folate to methyl donor for DNA methylation. Genetic variations in folate metabolism are believed to contribute to the risk of acute lymphoblastic leukemia, colon, esophageal and stomach cancer, as well as cardiovascular and cerebrovascular diseases. MTHFR C677T and A1298C polymorphisms are known to be risk factors for gastric cancer in the Chinese population. Therefore, we hypothesized that the MTHFR polymorphisms are associated with the risk of stomach cancer in Korean subjects. We conducted a Korean population-based case-control study to examine the relationship between genetic polymorphisms in MTHFR and risk of stomach cancer. The study subjects were 133 patients with stomach cancer and 445 population controls, matched according to sex and age. Genomic DNA was extracted from blood samples of the controls and from surgically resected "normal" tissues adjacent to the tumor of stomach cancer patients. MTHFR genotypes at the C677T and A1298C sites were analyzed by PCR-based RFLP methods. We found no evidence for an association between the MTHFR C677T and A1298C polymorphisms and stomach cancer in any of the subjects. The adjusted odds ratios and 95% confidence intervals for MTHFR C677T were 0.924 (0.581-1.469) for 677CT versus 677CC wild-type and 1.147 (0.850-1.549) for 677TT versus 677CC, and for MTHFR A1298C, they were 1.114 (0.695-1.783) for 1298AC versus 1298AA wild-type and 0.834 (0.284-2.450) for 1298CC versus 1298AA. These results suggest that the MTHFR C677T and A1298C polymorphisms by themselves do not play an important role in the etiology of stomach cancer in the Korean population.

    Trace elemental analysis was carried out in the biological samples of carcinoma kidney and stomach using particle induced X-ray emission technique. A 2 MeV proton beam was employed to excite the samples. From the present results, the levels of elements K, Ca, Fe, Ni and Se are lower and those of the elements Ti, Co, Zn, As and Cd are higher in the cancer tissue of kidney than those observed in the normal tissue. In the case of stomach, the concentrations of elements Cl, K, Ca, Ti, Mn, Fe, Co, Cu and Zn are lower while concentrations of elements Cr, Ni, As and Br are higher in the cancer tissue of stomach than those observed in the normal tissue. The observed deficiency or excess of certain elements is correlated to carcinogenesis of that organ. The present results of carcinoma stomach support the previous observations that nickel and chromium are carcinogenic agents. The low levels of selenium observed in the carcinoma tissue of kidney and the low levels of manganese observed in the carcinoma tissue of stomach support the view that selenium and manganese inhibit the growth of cancer in kidney and stomach respectively. The observed high levels of zinc in the cancer tissue of kidney suggest that zinc is involved in the tumor growth and development of neoplastic transformation in kidney while the observed low levels of zinc in the carcinoma tissue of stomach suggest that zinc inhibits the growth of cancer in this organ. For correctly assessing the role played by the trace elements in initiating, promoting or inhibiting cancer in various organs, there is a need for acquisition of more data by trace elemental analysis from several investigations of this type undertaken in different regions

  20. Edge detection of barium-filled stomach picture by one-dimensional collation method

    The method for the contour edge detection of barium- filled stomach pictures by X-ray for the automatic screening is described using computer technique. It is necessary for the automatic screening of barium- filling pictures to detect accurately the outline of stomachs because the analysis of repletion pictures is performed by checking the disorder of marginal contours and abnormal stomach shapes. However, the detection of the coutour lines is difficult to be successful for the reason that the contrast of stomach pictures to background is low, a stomach is not necessarily filled completely with barium and the shadow of barium flowing into intestines is superimposed on stomach images and the shading is likely to occur. The engineering processing against these problems is not yet solved. In order to reduce the noise due to differential operator, the proposed method determines the boundary of a thing generally by the threshold value of density, and defines the edge of the thing from the differential waveform of density in the vicinity of the boundary. In addition, the method corrects the detection error caused by the local nonconformity of parameters by comparing the edges between the adjacent lines. As a result, in spite of its simple algorithm, the edges with good continuity and less noise can be detected, and the method is not much affected by shading. This method was found to be applicable to the images of others than stomachs. The extraction of the contour of barium- filling pictures requires the high level recognition processing instead of the simple conditioning. (Wakatsuki, Y.)

    To investigate if oral omeprazole application induces cancers of fore and glandular stomach in mice. A total of 66 eligible male mice were randomly divided into 6 groups, which were treated with control reagent, low (6 mg/kg) and high dose omeprazole (30 mg/kg), N-methyl-N'-nitro-N-nitrosoguanidine (MNNG, 100 mg/L water), and MNNG plus low and high dose omeprazole, respectively. After 24 weeks, concentrations of acid phosphatase (ACP) and N-acetyl-β-D-glucosaminidase(NAG) in serum and spleen was examined, and p21 and mTOR levels in stomach were detected. The mouse spleen weight index was smaller in the omeprazole group than the control group, and in the MNNG plus omeprazole groups than the MNNG group. In the fore-stomach, more carcinomas were observed in the MNNG plus omeprazole groups than in the MNNG group. In the glandular stomach, there existed more atypical hyperplasia cases in the MNNG plus omeprazole groups than the MNNG-treated group, and one carcinoma was induced in the MNNG plus high dose omeprazole group. Omeprazole alone caused minor gastric pathological changes. Omeprazole treatment lowered both serum and spleen ACP and NAG levels in both the non-MNNG-treated and MNNG-treated subgroups. In fore-stomach, there existed decreased p21 and mTOR levels in the omeprazole-treated groups than in the control group, and in the MNNG plus omeprazole groups than the MNNG-treated group. Omeprazole promotes carcinogenesis of the mouse fore-stomach but not the glandular stomach following treatment with MNNG. Lysosomal hydrolase activity was inhibited and some cancer-associated proteins was dysregulated, which requires further explorations.

    Stomach cancer is one of leading causes of death worldwide. In Thailand, the incidence and mortality of stomach cancer are in the top ten for cancers. Effects of DNA repair gene X-ray repair cross complementary protein 1 (XRCC1) polymorphisms and clinicopathological characteristics on survival of stomach cancer in Thailand have not been previously reported. The aim of this study was to investigate the effects of XRCC1 gene and clinicopathological characteristics on survival of stomach cancer patients in Thailand. Data and blood samples were collected from 101 newly diagnosed stomach cancer cases pathologically confirmed and recruited during 2002 to 2006 and followed-up for vital status until 31 October 2012. Genotype analysis was performed using real-time PCR-HRM. The data were analyzed using the Kaplan-Meier method to yield cumulative survival curve, log-rank test to assess statistical difference of survival and Cox proportional hazard models to estimate adjusted hazard ratio. The total followed-up times were 2,070 person-months, and the mortality rate was 4.3 per 100 person-months. The median survival time after diagnosis was 8.07 months. The cumulative 1-, 3-, 5-years survival rates were 40.4%, 15.2 % and 10.1 % respectively. After adjustment, tumour stage were associated with an increased risk of death (p= 0.036). The XRCC1 Gln339Arg, Arg/Arg homozygote was also associated with increased risk but statistically this was non-significant. In addition to tumour stage, which is an important prognostic factor affecting to the survival of stomach cancer patients, the genetic variant Gln339Arg in XRCC1 may non-significantly contribute to risk of stomach cancer death among Thai people. Larger studies with different populations are need to verify ours findings.

    Depression in cancer survivors affects the rest of their lives in many ways. To estimate the prevalence of depression and identify associated factors in disease-free stomach cancer survivors. We enrolled 391 stomach cancer survivors who had been disease-free for at least one year after surgery from the cancer registries of two hospitals in Korea. Stomach cancer survivors were mailed a survey that included the Beck Depression Inventory, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30, and the associated stomach module, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Stomach Cancer Module 22. Forty-four percent of survivors suffered from depression, and more women (49%) than men (42%) had high depression scores (Beck Depression Inventory >13). In multiple logistic regression analysis, lower income (odds ratio [OR] 2.49; 95% CI 1.64-3.78), problems with care before treatment (OR 1.92; 95% CI 1.23-2.98), body image change (OR 2.23; 95% CI 1.41-3.53), and symptoms of fatigue (OR 3.11; 95% CI 1.49-6.52), dyspnea (OR 2.57; 95% CI 1.48-4.45), or insomnia (OR 4.51; 95% CI 1.88-10.83) were associated with depression. The prevalence of depression was high in stomach cancer survivors even after the completion of treatment, especially among those with problems amenable to treatment, and we identified the associated factors. We suggest that stomach cancer survivors should be screened for depression after the end of treatment. Copyright © 2013 U.S. Cancer Pain Relief Committee. Published by Elsevier Inc.

    Recent investigations revealed that lysophosphatidic acid (LPA), a phospholipid with a growth factor-like activity, plays an important role in the integrity of the gastrointestinal tract epithelium. This paper attempts to clarify the effect of orally administered phosphatidic acid (PA) and LPA on aspirin-induced gastric lesions in mice. Phospholipids, a free fatty acid, a diacylglycerol and a triglyceride at 1 mM (5.7 μmol/kg body weight) or 0.1 mM were orally administered to mice 0.5 h before oral administration of aspirin (1.7 mmol/kg). The total length of lesions formed on the stomach wall was measured as a lesion index. Formation of LPA from PA in the mouse stomach was examined by in vitro (in stomach lavage fluid), ex vivo (in an isolated stomach) and in vivo (in the stomach of a living mouse) examinations of phospholipase activity. Palmitic acid, dioleoyl-glycerol, olive oil and lysophosphatidylcholine did not affect the aspirin-induced lesions. In contrast, phosphatidylcholine (1 mM), LPA (1 mM) and PA (0.1, 1 mM) significantly reduced the lesion index. Evidence for formation of LPA from PA in the stomach by gastric phospholipase A2 was obtained by in vitro, ex vivo and in vivo experiments. An LPA-specific receptor, LPA2, was found to be localized on the gastric surface-lining cells of mice. Pretreatment with PA-rich diets may prevent nonsteroidal anti-inflammatory drug-induced stomach ulcers.

    Information on familial resemblance is important for the design of effective family-based interventions. We aimed to quantify familial correlations and estimate the proportion of variation attributable to genetic and shared environmental effects (i.e., familiality) for dietary intake variables and determine whether they vary by generation, sex, dietary quality, or by the age of the children. The study sample consisted of 1435 families (1007 mothers, 438 fathers, 1035 daughters, and 1080 sons) from the multi-center I.Family study. Dietary intake was assessed in parents and their 2-19 years old children using repeated 24-h dietary recalls, from which the usual energy and food intakes were estimated with the U.S. National Cancer Institute Method. Food items were categorized as healthy or unhealthy based on their sugar, fat, and fiber content. Interclass and intraclass correlations were calculated for relative pairs. Familiality was estimated using variance component methods. Parent-offspring ( r = 0.11-0.33), sibling ( r = 0.21-0.43), and spouse ( r = 0.15-0.33) correlations were modest. Parent-offspring correlations were stronger for the intake of healthy ( r = 0.33) than unhealthy ( r = 0.10) foods. Familiality estimates were 61% (95% CI: 54-68%) for the intake of fruit and vegetables and the sum of healthy foods and only 30% (95% CI: 23-38%) for the sum of unhealthy foods. Familial factors explained a larger proportion of the variance in healthy food intake (71%; 95% CI: 62-81%) in younger children below the age of 11 than in older children equal or above the age of 11 (48%; 95% CI: 38-58%). Factors shared by family members such as genetics and/or the shared home environment play a stronger role in shaping children's intake of healthy foods than unhealthy foods. This suggests that family-based interventions are likely to have greater effects when targeting healthy food choices and families with younger children, and that other sorts of intervention are needed to

  6. NALCN ion channels have alternative selectivity filters resembling calcium channels or sodium channels.

    Directory of Open Access Journals (Sweden)

    Adriano Senatore

    Full Text Available NALCN is a member of the family of ion channels with four homologous, repeat domains that include voltage-gated calcium and sodium channels. NALCN is a highly conserved gene from simple, extant multicellular organisms without nervous systems such as sponges and placozoans and mostly remains a single gene compared to the calcium and sodium channels which diversified into twenty genes in humans. The single NALCN gene has alternatively-spliced exons at exons 15 or exon 31 that splices in novel selectivity filter residues that resemble calcium channels (EEEE or sodium channels (EKEE or EEKE. NALCN channels with alternative calcium, (EEEE and sodium, (EKEE or EEKE -selective pores are conserved in simple bilaterally symmetrical animals like flatworms to non-chordate deuterostomes. The single NALCN gene is limited as a sodium channel with a lysine (K-containing pore in vertebrates, but originally NALCN was a calcium-like channel, and evolved to operate as both a calcium channel and sodium channel for different roles in many invertebrates. Expression patterns of NALCN-EKEE in pond snail, Lymnaea stagnalis suggest roles for NALCN in secretion, with an abundant expression in brain, and an up-regulation in secretory organs of sexually-mature adults such as albumen gland and prostate. NALCN-EEEE is equally abundant as NALCN-EKEE in snails, but is greater expressed in heart and other muscle tissue, and 50% less expressed in the brain than NALCN-EKEE. Transfected snail NALCN-EEEE and NALCN-EKEE channel isoforms express in HEK-293T cells. We were not able to distinguish potential NALCN currents from background, non-selective leak conductances in HEK293T cells. Native leak currents without expressing NALCN genes in HEK-293T cells are NMDG(+ impermeant and blockable with 10 µM Gd(3+ ions and are indistinguishable from the hallmark currents ascribed to mammalian NALCN currents expressed in vitro by Lu et al. in Cell. 2007 Apr 20;129(2:371-83.

We extended those findings in two studies that investigated the contribution of resemblance to emotion expressions and attractiveness to younger adults (YA and older adults (OA age and gender stereotypes on the dimensions of warmth and competence. Using connectionist modeling of facial metrics of 240 neutral younger and older faces, Study 1 found that, neutral expression older faces or female faces showed greater structural resemblance to happy expressions and less resemblance to angry expressions than did younger or male faces, respectively. In addition, neutral female faces showed greater resemblance to surprise expressions.

We found that YA, but not OA, age stereotypes replicated previous research showing higher perceived warmth and lower perceived competence in older adults. In addition, previously documented gender stereotypes were moderated by face age for both YA and OA. The greater attractiveness of younger than older faces and female than male faces influenced age and gender stereotypes, including these deviations from prior research findings using category labels rather than faces. On the other hand, face age and face sex differences in emotion resemblance did not influence age or gender stereotypes, contrary to prediction. Our results provide a caveat to conclusions about age and gender stereotypes derived from responses to category labels, and they reveal the importance of assessing stereotypes with a methodology that is sensitive to influences of group differences in appearance that can exacerbate or mitigate stereotypes in more ecologically valid contexts.

    Full Text Available Streptococcus (S. suis translocates across the intestinal barrier of piglets after intraintestinal application. Based on these findings, an oro-gastrointestinal infection route has been proposed. Thus, the objective of this study was to investigate the survival of S. suis in the porcine stomach. Whereas surviving bacteria of S. suis serotypes 2 and 9 were not detectable after 60 min of incubation in stomach contents with a comparatively high gastric pH of 5 due to feeding of fine pellets, the number of Salmonella Derby bacteria increased under these conditions. Further experiments confirmed the clearance of S. suis serotypes 2 and 9 within 30 min in stomach contents with a pH of 4.7 independently of the bacterial growth phase. Finally, an oral infection experiment was conducted, feeding each of 18 piglets a diet mixed with 1010 CFU of S. suis serotype 2 or 9. Thorough bacteriological screenings of various mesenteric-intestinal lymph nodes and internal organs after different times of exposure did not lead to any detection of the orally applied challenge strains. In conclusion, the porcine stomach constitutes a very efficient barrier against oro-gastrointenstinal S. suis infections. Conditions leading to the passage of S. suis through the stomach remain to be identified.

    Using stored serum samples collected from 1970-72 and/or from 1977-79, serum ferritin, transferrin, and ceruloplasmin levels were immunologically determined for 233 stomach cancer and 84 lung cancer cases diagnosed from 1973-83 and for 385 matched controls from a fixed population of Hiroshima and Nagasaki atomic bomb survivors. Elevated stomach cancer risk was associated with low serum ferritin levels, with more than a threefold excess among those in the lowest quintile as compared to the highest ferritin quintile. The average serum ferritin concentration was 8% lower in the stomach cancer cases than in the controls. Risk did not vary with the time between blood collection and stomach cancer onset, remaining high among those with low ferritin levels five or more years before cancer diagnosis. Low ferritin combined with achlorhydria, diagnosed about 10 years before the blood collection and up to 25 years before cancer diagnosis, was an exceptionally strong marker of increased stomach cancer risk. No effect of transferrin or ceruloplasmin independent of ferritin was observed on gastric cancer risk. Lung cancer risk was not related to these three serum proteins. (author)

    Background: Stomach cancer is one of the five most common cancers in Iran. This study examined the effectiveness of a mobile telephone short-message service (SMS) based-education intervention using Health Belief Model (HBM) variables in improving dietary behavior in terms of stomach cancer prevention among a sample of Iranian female college students. Materials and Methods: In this quasi-experimental study, 124 female college students in the dormitories of Yazd University, Yazd, Iran were randomly selected and assigned to either the intervention (n=62) or the control group (n=62). Information (data) regarding HBM variables and dietary behavior related to stomach cancer prevention was collected by a self-administrated questionnaire. Forty eight messages were designed and sent to the participants’ phones in the intervention group during the 48-day intervention period. Two groups were followed-up one month after the intervention delivered via SMS. Results: There were significant differences in HBM variables (except for the perceived severity) and the preventive dietary behaviors for stomach cancer in the intervention group compared to the comparison group following the education intervention delivered via SMS. Conclusions: SMS-delivered nutrition education intervention can be a practical strategy to improve dietary behavior related to stomach cancer prevention. Creative Commons Attribution License

    The stomach, a hallmark of gnathostome evolution, represents a unique anatomical innovation characterized by the presence of acid- and pepsin-secreting glands. However, the occurrence of these glands in gnathostome species is not universal; in the nineteenth century the French zoologist Cuvier first noted that some teleosts lacked a stomach. Strikingly, Holocephali (chimaeras), dipnoids (lungfish) and monotremes (egg-laying mammals) also lack acid secretion and a gastric cellular phenotype. Here, we test the hypothesis that loss of the gastric phenotype is correlated with the loss of key gastric genes. We investigated species from all the main gnathostome lineages and show the specific contribution of gene loss to the widespread distribution of the agastric condition. We establish that the stomach loss correlates with the persistent and complete absence of the gastric function gene kit--H(+)/K(+)-ATPase (Atp4A and Atp4B) and pepsinogens (Pga, Pgc, Cym)--in the analysed species. We also find that in gastric species the pepsinogen gene complement varies significantly (e.g. two to four in teleosts and tens in some mammals) with multiple events of pseudogenization identified in various lineages. We propose that relaxation of purifying selection in pepsinogen genes and possibly proton pump genes in response to dietary changes led to the numerous independent events of stomach loss in gnathostome history. Significantly, the absence of the gastric genes predicts that reinvention of the stomach in agastric lineages would be highly improbable, in line with Dollo's principle.

    To determine the spinal innervation and neuronal connections is important for studying gastric carbohydrate metabolism and motor responses. Neurons involved in the efferent control of the stomach were identified following visualization of pseudorabies virus (PRV)-614 retrograde tracing. PRV-614 was injected into the ventral stomach wall in 13 adult C57BL/6J strain male mice. On the fifth day postinjection, animals were humanely sacrificed, and spinal cords were removed and sectioned, and processed for PRV visualization. The virus injected into the ventral stomach wall was specifically transported to the thoracic spinal cord. At 5 d after injection of the PRV-614, stomach enlargement and tissue edema were found, and PRV-614 positive cells were found in the intermediolateral cell column, the intercalates nucleus or the central autonomic nucleus of spinal cord segments T3 to L1, and major PRV-614 labeled cells were focused in the T6-10 segment. Our results revealed neuroanatomical circuits between stomach and the spinal intermediolateral cell column neurons.

    Although long thought to be a sterile organ, due to its acid production, the human stomach holds a core microbiome. To provide an update of findings related to gastric microbiota and its link with gastric diseases. We conducted a systematic review of the literature. The development of culture-independent methods facilitated the identification of many bacteria. Five major phyla have been detected in the stomach: Firmicutes, Bacteroidites, Actinobacteria, Fusobacteria and Proteobacteria. At the genera level, the healthy human stomach is dominated by Prevotella, Streptococcus, Veillonella, Rothia and Haemophilus; however, the composition of the gastric microbiota is dynamic and affected by such factors as diet, drugs and diseases. The interaction between the pre-existing gastric microbiota and Helicobacter pylori infection might influence an individual's risk of gastric disease, including gastric cancer. The maintenance of bacterial homeostasis could be essential for the stomach's health and highlights the chance for therapeutic interventions targeting the gastric microbiota, even if gastric pH, peristalsis and the mucus layer may prevent bacteria colonization; and the definition of gastric microbiota of the healthy stomach is still an ongoing challenging task.

    Stomach contents analysis (SCA) provides a snap-shot observation of a consumer's diet. Interpretation of SCA data can be complicated by many factors, including variation in gastric residence times and digestion rates among prey taxa. Although some SCA methods are reported to efficiently remove all stomach contents, the effectiveness of these techniques has rarely been tested for large irregular shaped prey with hard exoskeletons. We used a controlled feeding trial to estimate gastric residency time and decomposition rate of a large crustacean prey item, the Blue Crab (Callinectes sapidus), which is consumed by American Alligators (Alligator mississippiensis), an abundant apex predator in coastal habitats of the southeastern United States. The decomposition rate of C. sapidus in the stomachs of A. mississippiensis followed a predictable pattern, and some crab pieces remained in stomachs for at least 14 days. We also found that certain portions of C. sapidus were prone to becoming caught within the stomach or esophagus, meaning not all crab parts are consistently recovered using gastric lavage techniques. However, because the state of decomposition of crabs was predictable, it is possible to estimate time since consumption for crabs recovered from wild alligators. This information, coupled with a detailed understanding of crab distributions and alligator movement tactics could help elucidate patterns of cross-ecosystem foraging by the American Alligator in coastal habitats

    Stomach lineage specific gene products act as a protective barrier in the normal stomach and their expression maintains the normal physiological processes, cellular integrity and morphology of the gastric wall. However, the regulation of stomach lineage specific genes in gastric cancer (GC) is far less clear. In the present study, we sought to investigate the role and regulation of stomach lineage specific gene set (SLSGS) in GC. SLSGS was identified by comparing the mRNA expression profiles of normal stomach tissue with other organ tissue. The obtained SLSGS was found to be under expressed in gastric tumors. Functional annotation analysis revealed that the SLSGS was enriched for digestive function and gastric epithelial maintenance. Employing a single sample prediction method across GC mRNA expression profiles identified the under expression of SLSGS in proliferative type and invasive type gastric tumors compared to the metabolic type gastric tumors. Integrative pathway activation prediction analysis revealed a close association between estrogen-α signaling and SLSGS expression pattern in GC. Elevated expression of SLSGS in GC is associated with an overall increase in the survival of GC patients. In conclusion, our results highlight that estrogen mediated regulation of SLSGS in gastric tumor is a molecular predictor of metabolic type GC and prognostic factor in GC.

    The aim of this study was to evaluate the incidence and mortality of stomach cancer, and its relationship with the Human Development Index (HDI) and its components in Asia in 2012. This ecological study was conducted based on GLOBOCAN project of WHO for Asian countries. We assessed the correlations between standardized incidence rates (SIR) and standardized mortality rates (SMR) of stomach cancer with HDI and its components using SPSS18. A total of 696,231 cases (68.7% in males and 31.3% in females, ratio of 2.19:1) and 524,465 deaths (67.1% in men and 33.0% in women, ratio 2.03:1) were included in 2012. Five countries with the highest SIR of stomach cancer were Republic Korea, Mongolia, Japan, China and Tajikistan. Five countries with the highest SMR of stomach cancer were Mongolia, Tajikistan, Kyrgyzstan, Kazakhstan and China. Correlation between HDI and SIR was 0.241 (p = 0.106), in men 0.236 (p = 0.114) and in women -0.250 (p = 0.094). Also between HDI and SMR -0.250 (p = 0.871) in men -0.018 (p = 0.903) and in women -0.014 (p = 0.927). No significant correlation was observed between the SIR of stomach cancer, and the HDI and its dimensions, such as life expectancy at birth, mean years of schooling, and income level of the population.

    17 patient swallowed wooden objects have been observed. After abdomenoscopy a conventional X-ray study of the stomach has been made by routine contrast technique in polypositional conditions and fractionated resorption of the contrast matter and fixed creeping compression. A periodical control of the foreign body movement in distal direction is made. The following specific features of the X-ray image are pointed out: the presence of fluid and mucus in an empty hypotonic stomach; progressive intensifying hypotonia of the stomach; gradually increase of the fluid. In recumbent position the foreign bodies show a negative density of respective forms and size. In errect position they 'float' over the contrast matter against the background of the air bubble of the fornix, showing a positive-negative density. When staying for a longer time in the stomach their volume shows a moderate increase. Experimental investigations in-vitro with the same wooden bodies show certain differences in the X-ray image compared to one observed in-vivo, which is due to the presence of fluid and mucus in the stomach. 3 figs., 15 refs

    We have reported the effectiveness of laparoscopy-assisted stomach-partitioning gastrojejunostomy Roux-en-Y reconstruction (LASPGJ-RY) for gastric outlet obstruction (GOO). The aim of this study was to evaluate the surgical outcomes of totally laparoscopic stomach-partitioning gastrojejunostomy Roux-en-Y reconstruction (TLSPGJ-RY) for GOO. This retrospective study enrolled 19 consecutive patients with GOO. Surgical outcomes of LASPGJ-RY (LA group; n=8) and TLSPGJ-RY (TL group; n=11) between January 2004 and 2015 were compared. The patients' background characteristics, operative findings, postoperative complications, and period to starting postoperative chemotherapy were examined. Eligible cases included 6 patients with gastric cancer, 4 with pancreatic cancer, 4 with duodenal cancer, 4 with urologic malignancies, and 1 with benign duodenal stenosis. The patients' background characteristics were not significantly different. In surgical outcomes, there were no significant differences in operating time, bleeding, complications (≥Clavien-Dindo grade IIIA), and postoperative hospital stay between the groups. The time to resume diet was significantly shorter in the TL group (median, 3 d; range, 3 to 6 d) than in the LA group (median, 5 d; range, 3 to 7 d; P=0.0093), and the number of patients who could receive chemotherapy after surgery was significantly higher in the TL group (P=0.039). TLSPGJ-RY was a safe and feasible gastrojejunostomy procedure for GOO. TLSPGJ-RY might be useful for early resumption of oral intake after surgery.

    The basic understanding of the three dimensional structure of mucin is essential to understand its physiological function. Technology has been developed to achieve orientated porcine stomach mucin molecules. X-ray fiber diffraction of partially orientated porcine stomach mucin molecules show d-spacing signals at 2.99, 4.06, 4.22, 4.7, 5.37 and 6.5 Å. The high intense d-spacing signal at 4.22 Å is attributed to the antiparallel β-sheet structure identified in the fraction of the homology modeled mucin molecule (amino acid residues 800-980) using Nidogen-Laminin complex structure as a template. The X-ray fiber diffraction signal at 6.5 Å reveals partial organization of oligosaccharides in porcine stomach mucin. This partial structure of mucin will be helpful in establishing a three dimensional structure for the whole mucin molecule. Copyright © 2011 Elsevier Inc. All rights reserved.

    Background. The aims of this study were to determine whether a modified Qigong breathing exercise can reduce the sense of hunger and identify possible mechanisms. Methods. The results from the test group, which performed the exercise, are compared with the control group, which performed deep breathing. Intestinal pressure measurements, stomach pH monitoring, and participant surveys were used for assessment. Results. Stomach pH was increased by 3 (0.2) and intestinal pressure was reduced by 12 (0.5) mm Hg in the experimental group and did not change significantly in the control group. The study provides strong evidence that the exercise can significantly reduce, or even suppress the sense of hunger on an empty stomach. Conclusion. This breathing exercise provides comfort in different circumstances, such as lack of regular meals, limited volume or caloric diet, and even during temporary complete absence of food in therapeutic fasting.

    Arteriovenous malformations of the stomach are an uncommon cause of upper GI bleeding. We report a case of stomach arteriovenous malformation in an 85-year-old Asian man who presented with massive hematemesis. Initial esophagogastroduodenoscopy did not detect this lesion, but contrast multi-detector CT confirmed GI bleeding. Multi-detector CT revealed a mass of blood vessels underlying the submucosa that arose from the right gastroepiploic artery. Repeat esophagogastroduodenoscopy showed that the lesion was a submucosal tumor with erosion and without active bleeding in the lower body of the stomach on the greater curvature. We performed partial gastrectomy via laparoscopy-assisted surgery. The histopathological diagnosis was arteriovenous malformation. © 2016 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

    Full Text Available Hydrolycus armatus (dog fish is a Teleostei of Cynodontidae Family that forms a distinct group of Neotropical Characiformes. This species is a predator, pelagic, freshwater and carnivorous and ichthyophagic feeding habits. Biological studies on fish are important in fishery, already that they are used as parameters to keep the exploitation to sustainable levels. This study aimed to describe the stomach anatomy of H. armatus, in order to generate basic information of this body of this vertebrate. We used ten (10 specimens of H. armatus, from the Teles Pires, city of Carlinda-MT, being this dissected and analyzed. The stomach of saccular format presented the regions cardial, pyloric and fundic, last being this last larger than the others. The anatomical features presented by the liver and stomach of H. armatus confirmed the relationship between the anatomy of these organs and their feeding habits being these, therefore, characteristics of predatory species, carnivorous and preferably ichthyophagics.

    This study examined the change in the attenuation of X-rays with the ROI (Region of Interest) in DR (Digital Radiography) according to the stomach contents by manufacturing a tissue equivalent material phantom to simulate real stomach tissue based on the assumption that there is some attenuation of X-rays and a difference in imaging quality according to the stomach contents. The transit dosage by the attenuation of X-rays decreased with increasing protein thickness, which altered the average ROI values in the film and DR images. A comparison of the change in average ROI values of the film and DR image showed that the image in film caused larger density changes with varying thickness of protein than the image by DR. The results indicate that NPO (nothing by mouth) is more important in film system than in DR system.

    Tannic acid is a polyphenolic compound that could be labeled with technetium-99m. To produce about 90% yield of  99mTc-tannic acid in acidic media (pH), the conditions required were 150 μg tin chloride, 30 min reaction time, and 200 μg of the substrate. 99mTc-tannic was stable for 6 h. Oral biodistribution of 99mTc-tannic showed that it concentrated in the stomach ulcer to reach about 50% of the total injected dose at 1 h after orall administration. This concentration of 99mTc-tannic in stomach ulcer may be sufficient to radio-image the presence of ulcer in the stomach. PMID:22389852

    Hexavalent chromium (Cr6) is a drinking water contaminant that has been detected in most of the water systems throughout the United States. In 2-year drinking water bioassays, the National Toxicology Program (NTP) found clear evidence of carcinogenic activity in male and female rats and mice. Because reduction of Cr6 to trivalent chromium (Cr3) is an important detoxifying step in the gastrointestinal (GI) tract prior to systemic absorption, models have been developed to estimate the extent of reduction in humans and animals. The objective of this work was to use a revised model of ex vivo Cr6 reduction kinetics in gastric juice to analyze the potential reduction kinetics under in vivo conditions for mice, rats and humans. A published physiologically-based pharmacokinetic (PBPK) model was adapted to incorporate the new reduction model. This paper focuses on the toxicokinetics of Cr6 in the stomach compartment, where most of the extracellular Cr6 reduction is believed to occur in humans. Within the range of doses administered by the NTP bioassays, neither the original nor revised models predict saturation of stomach reducing capacity to occur in vivo if applying default parameters. However, both models still indicate that mice exhibit the lowest extent of reduction in the stomach, meaning that a higher percentage of the Cr6 dose may escape stomach reduction in that species. Similarly, both models predict that humans exhibit the highest extent of reduction at low doses. - Highlights: • We outline a new in vivo model for hexavalent chromium reduction in the stomach. • We examine in vivo reduction for mice, rats, and humans under varying conditions. • Species differences in toxicokinetics may explain susceptibility. • We show that a simplified stomach reduction model is adequate for extrapolation. • Internal dose uncertainties still exist.

    Laparoscopic sleeve gastrectomy (LSG) was initially performed as the first stage of biliopancreatic diversion with duodenal switch for the treatment of super-obese or high-risk obese patients but is now most commonly performed as a standalone operation. The aim of this prospective study was to investigate outcomes after LSG according to resected stomach volume. Between May 2011 and April 2013, LSG was performed in 102 consecutive patients undergoing bariatric surgery. Two patients were excluded, and data from the remaining 100 patients were analyzed in this study. Patients were divided into three groups according to the following resected stomach volume: 700-1,200 mL (group A, n = 21), 1,200-1,700 mL (group B, n = 62), and >1,700 mL (group C, n = 17). Mean values were compared among the groups by analysis of variance. The mean percentage excess body weight loss (%EBWL) at 3, 6, 12, and 24 months after surgery was 37.68 ± 10.97, 50.97 ± 13.59, 62.35 ± 11.31, and 67.59 ± 9.02 %, respectively. There were no significant differences in mean %EBWL among the three groups. Resected stomach volume was greater in patients with higher preoperative body mass index and was positively associated with resected stomach weight. Mean %EBWL after LSG was not significantly different among three groups of patients divided according to resected stomach volume. Resected stomach volume was significantly greater in patients with higher preoperative body mass index.

    Uridine 5'-diphospho-glucuronosyltransferases (UGT) are the key players in the biotransformation of drugs, xenobiotics, and endogenous compounds. Particularly, UDP-glucuronosyltransferase 1A (UGT1A) participates in a wide range of biological and pharmacological processes and plays a critical role in the conjugation of endogenous and exogenous components. Thirteen alternative splicing products were produced from UGT1A gene locus designated as UGT1A1 and UGT1A3-10. A growing amount of evidence suggests that they have important roles in the carcinogenesis which is well documented by colon, liver, pancreas, and kidney cancer studies. Here, we report differential expressions of UGT1A genes in normal and tumor tissues of stomach cancer patients. Total numbers of 49 patients were enrolled for this study, and expression analysis of UGT1A genes was evaluated by the real-time PCR method. Accordingly, UGT1A1, UGT1A8, and UGT1A10 were found to be upregulated, and UGT1A3, UGT1A5, UGT1A7, and UGT1A9 were downregulated in stomach tumors. No expression changes were observed in UGT1A4. Also, UGT1A6 transcription variants were significantly upregulated in stomach cancer tissues compared to normal stomach tissue. Additionally, UGT1A7 gene showed highest expression in both normal and tumoral tissues, and interestingly, UGT1A7 gene expression was significantly reduced in stage II patients as compared to other patients. In conclusion, UGT1A genes are differentially expressed in normal and tumoral stomach tissues and expression changes of these genes may affect the development and progression of various types of cancer including the cancer of the stomach.

    The risk of indoor air radon for lung cancer is well studied, but the risks of groundwater radon for both lung and stomach cancer are much less studied, and with mixed results. Geomasked and geocoded stomach and lung cancer cases in North Carolina from 1999 to 2009 were obtained from the North Carolina Central Cancer Registry. Models for the association with groundwater radon and multiple confounders were implemented at two scales: (i) an ecological model estimating cancer incidence rates at the census tract level; and (ii) a case-only logistic model estimating the odds that individual cancer cases are members of local cancer clusters. For the lung cancer incidence rate model, groundwater radon is associated with an incidence rate ratio of 1.03 [95% confidence interval (CI) = 1.01, 1.06] for every 100 Bq/l increase in census tract averaged concentration. For the cluster membership models, groundwater radon exposure results in an odds ratio for lung cancer of 1.13 (95% CI = 1.04, 1.23) and for stomach cancer of 1.24 (95% CI = 1.03, 1.49), which means groundwater radon, after controlling for multiple confounders and spatial auto-correlation, increases the odds that lung and stomach cancer cases are members of their respective cancer clusters. Our study provides epidemiological evidence of a positive association between groundwater radon exposure and lung cancer incidence rates. The cluster membership model results find groundwater radon increases the odds that both lung and stomach cancer cases occur within their respective cancer clusters. The results corroborate previous biokinetic and mortality studies that groundwater radon is associated with increased risk for lung and stomach cancer. © The Author 2016; all rights reserved.

    The authors report a localized (primary) conjunctival marginal zone B-cell lymphoma (mucosa-associated lymphoid tissue (MALT)-type), with amyloid deposition with relapse in the stomach, 14 months after the initial diagnosis. Ocular adnexal marginal zone B-cell MALT lymphoma is often localized at diagnosis; some relapse in typical MALT sites. There are few reports of localized conjunctival lymphoma with a relapse in the stomach. The authors suggest that all patients with localized ocular adnexal lymphoma be followed for an extended period.

    Breast carcinoma exceptionally leads to metastatic linitis plastica. Distinguishing a breast cancer metastasis to the stomach from a primary gastric cancer on the basis of clinical and radiological signs is very challenging. Thanks to being cognizant of the previous history of invasive lobular carcinoma and the gastric biopsy followed by immunohistochemical analysis, gastric metastasis can be diagnosed. Despite the use of chemotherapy and hormonal therapy, gastric metastasis remains often associated with poor prognosis. We present a case where gastric biopsy allowed a metastatic breast cancer to the stomach to be diagnosed and we discuss its clinical, diagnostic, pathological and therapeutic particularities.

    Solution rules in the form of differential-diagnositc tables with coefficients of weight and threshold values of 16 different signs were obtained with the help of a computer EC-assisted algorithm of a generalized picture. These signs included tumor antigens, cyclonucleotides and hormones determined in the blood serum of healthy individuals, stomach cancer patients and patients with diseases of nonmalignant origin by means of radioimmunoassay. These signs being of low informative value by themselves, in a combined use provided an opportunity to differentiate between ''stomach cancer-not cancer'' with a sufficiently high degree of significance

    The complex physiology of the gastrointestinal (GI) tract must permanently be adjusted according to the composition of ingested food, which requires continuous monitoring by appropriate sensory systems. Sensing the dietary constituents is thought to be mediated by chemosensory cells residing in the mucosa of the GI tract. We have examined the appearance and differentiation of candidate chemosensory cells at distinct postnatal stages and visualized cells that express gustducin or TRPM5. Two critical stages have been considered: the suckling period when the neonates are nourished exclusively on milk and the weaning period when the diet gradually changes to solid food. At early postnatal stages, only a few gustducin- or TRPM5-expressing cells have been found; they display an immature morphology. At the time of weaning, numerous gustducin- or TRPM5-positive cells are present in the gastric mucosa and are isomorphic to adult candidate chemosensory cells. The typical accumulation of gustducin and TRPM5 cells at the border between the forestomach and corpus region and the characteristic tissue fold or "limiting ridge" have not been observed at early postnatal stages but are complete at the time of weaning. The appearance of candidate chemosensory cells at the strategic position occurs within the last few days before weaning but after the formation of the limiting ridge. Thus, both the topographic arrangement of the cells and the limiting ridge seem to be important features for the processing of solid food in the mouse stomach.

    Background. Gastric cancer is one of the leading malignancies with a poor prognosis and low survival rates. Although the mechanisms underlying its development are still unknown, there is a consensus that genetic instability, inactivation of tumor suppressor genes and over-expression of oncogenes are involved in the early and late stages of gastric carcinogenesis. In the present study we wanted to display differential expression of seven oncogenes, namely CCNE1, EGF, ERBB3, FGF4, HRG1, HGFR and TDGF1. Patients and methods. We employed a method based on the multiplex reverse transcription polymerase chain (RT-PCR) method with a fluorescence detection. Results. More than half of patients (74.3%) out of total 74 with gastric adenocarcinoma had over-expressed at least one oncogene, with the exception of FGF4, which was expressed in tumor tissue of less than one third of patients. 56.8% of the patients patients showed over-expression of two or more oncogenes. Conclusions. Patients with precancerous lesions had elevated levels of TDGF1 or cripto-1 (64.9%) and CCNE1 (57.1%), suggesting that they could be used as markers for an early detection of malignant changes in stomach. Finally, the fluorescent multiplex RT-PCR method could be of value for rapid assessment of oncogene mRNA levels in small samples of tumor or precancerous biopsies. (author)

    Full Text Available Abstract Background The polycystic ovary syndrome (PCOS affects approximately 6-10% of women of reproductive age and is characterized by chronic anovulation and hyperandrogenism. However, a comprehensive understanding of the mechanisms that dictate androgen overproduction is lacking, which may account for inconsistencies between measures of androgen excess and clinical presentation in individual cases. Methods A rat model of PCOS was established by injecting dehydroepiandrosterone sulfoconjugate (DHEAS into pregnant females. Rats were administered with DHEAS (60 mg/kg/d subcutaneously (s.c. for all 20 days of pregnancy (Group A, or for the first 10 days (Group B, or from day 11 to day 20 (Group C. Controls were administered with injection oil (0.2 ml/day s.c. throughout pregnancy (Group D. The litter rate, abortion rate, and offspring survival rate in each group were recorded. Serum androgen and estrogen were measured and the morphological features of the ovaries were examined by light and electron microscopy in the offspring of each group. Results We found that rats injected with DHEAS throughout pregnancy (group A lost fertility. Rats injected with DHEAS during early pregnancy (group B exhibited more serious aberrations in fertility than both Group C, in which rats were injected with DHEAS during late pregnancy (P  Conclusions Our results indicate that androgen excess during pregnancy can decrease rat fertility. Excess androgen at the early stage of pregnancy causes high reproductive toxicity, leading to abnormality of ovarian morphology and functions in female offspring.

    Prevention and early detection are key elements for the reduction of stomach cancer mortality. To apply pertinent measures effectively, high-risk groups need to be identified. With this aim, we assessed stomach cancer mortality among migrants from the Former Soviet Union (FSU), a high-risk area, to Germany and Israel. We calculated standardized mortality ratios (SMRs) comparing stomach cancer mortality in two retrospective migrant cohorts from the FSU to Germany (n=34,393) and Israel (n=589,388) to that in the FSU and the host country. The study period ranges from 1990 to 2005 in Germany and from 1990 to 2003 in Israel. Vital status and cause of death were retrieved from municipal and state registries. To assess secular mortality trends, we calculated annual age-standardized mortality rates in the cohorts, the FSU, and the two host countries and conducted Poisson regression modeling. SMRs (95% confidence intervals) for men in the German migrant cohort were 0.51 (0.36-0.70) compared with the FSU population and 1.44 (1.04-1.99) compared with the German population, respectively. For women, SMRs were 0.73 (0.49-1.03) compared with the FSU population and 1.40 (0.98-1.99) compared with the German population. SMRs for men in the Israeli migrant cohort were 0.49 (0.45-0.53) compared with the FSU population and 1.79 (1.65-1.94) compared with the Israeli population. SMRs for women in the Israeli cohort were 0.65 (0.59-0.72) compared with the FSU population and 1.82 (1.66-1.99) compared with the Israeli population. Poisson modeling showed a secular decrease in all populations with a time lag of 4-5 years between migrants and 'natives' in Germany and converging rates between migrants and the general population in Israel. Stomach cancer mortality in migrants from the FSU remains elevated after migration to Germany and Israel but is much lower than in the FSU. Due to a secular decline, it can be expected that mortality among migrants from the FSU reaches within a few years

    It is well known that human behavior and individual psychological traits are moderately to substantially heritable. Over the past decade, an increasing number of studies have explored the genetic and environmental influence on religiousness. These studies originate predominantly from countries generally considered more religious than the very secular northern European countries. Comparisons of the results are complicated by diverse definitions of religiousness, but several studies indicate that the influence of the family environment is most predominant in early life, whereas genetic influences increase with age. We performed a population-based twin study of religiousness in a secular society using data from a Web-based survey sent to 6,707 Danish twins born 1970-1989, who were identified in the Danish Twin Registry. We applied Fishman's three conceptual dimensions of religiousness: cognition, practice, and importance. In all polygenic models and biometric analyses, we controlled for gender and age. The study sample comprised 2,237 same sex twins, a response rate of 45%. We found high correlations within both monozygotic and dizygotic twin pairs in most items of religiousness, indicating a large influence from shared environmental factors. Personal religiousness such as praying to God, believing in God, and finding strength and comfort in religion were more influenced by genetic factors than were social forms of religiousness such as church attendance. We found a small tendency for increasing genetic influence with increasing age for some religious items, but not for all.

    Full text: Introduction: Bezoar formations are formed in the stomach of ingested foreign particles. In most cases those foreign particles are organic, such as hair, plant fibers, seeds, fruit and vegetables and more. According to their composition bezoars are divided into trihobezoari (composed of hair), fitobezoari (composed of vegetable particles), mixed and others. The most common bezoars are trihobezoars. They are formed by chewing and swallowing hair, especially in girls or occupational disease in people who work with wool (brushmakers). Aim: The aim of this study is to demonstrate the value of non-conventional imaging methods, ultrasound, CT and MRI in the diagnosis of trihobezoar in the stomach. Material and methods: Patient of 70 years is hospitalized in Gastrointestinal ward with abdominal pain, nausea, vomiting, a feeling of satiation and weight loss. At physical examination a moving epigastric formation was found with the following characteristics: size 4-5 cm, smooth, hard surface. The patient was carried out echographic, CT and MRI examinations. Results: With the echographic examination in the lumen of the stomach, it was found mainly hipoehogenic formation of relatively sharp and smooth lines and multiple hyperechogenic inclusions. CT results - the described formation is visualized as a parenchymal lesion with a homogeneous structure and smooth contours. MRI results - the gastric formation appears as hipointensiv mainly in T1 and T2 sequences respectively in T1 and T2 hipointensive areas. The patient underwent surgery and was ultimately diagnosed with trihobezoar in the stomach

    Stomach cancer belongs to the most common malignant tumors in Portugal. Main causal factors are age, dietary habits, smoking, and Helicobacter pylori infections. As these factors do not only operate on different time dimensions, such as age, period, or birth cohort, but may also vary along space, it is of utmost interest to model temporal and spatial trends jointly. In this paper, we analyze incidence of stomach cancer in Southern Portugal between 1998 and 2006 for females and males jointly using a spatial multivariate age-period-cohort model. Thus, we avoid age aggregation and allow the exploration of heterogeneous time trends between males and females across age, period, birth cohort, and space. Model estimation is performed within a Bayesian setting assuming (gender specific) smoothing priors. Our results show that the posterior expected rate of stomach cancer is decreasing for all counties in Southern Portugal and that males around 70 have a two times higher risk of getting stomach cancer compared with their female counterparts. We further found that, except for some few counties, the spatial influence is almost constant over time and negligible in the southern counties of Southern Portugal. © 2014 WILEY-VCH Verlag GmbH & Co.
