The results showed that delay chilling significantly improved μ-calpain activities (P<0.05) and enhanced the tenderness of bovine M. longissimus during earlier aging periods compared with conventional chilling. But in later aging periods,delay chilling weakened the effect on the tenderness of beef because of premature consumption of μ-calpain. The experiment results confirmed that delay chilling improved the rate of postmortem aging of beef and remarkably enhanced the tenderness of beef through the effect of delay chilling on μ-calpain activities. 展开更多

The growth inhibitory effects of D-glucosamine hydrochloride (GlcNH2-HCl), D-glucosamine (GlcNH2) and N-acetyl glucosamine (NAG) on human hepatoma SMMC-7721 cells in vitro were investigated. The results showed that GlcNH2.HCl and GlcNH2 resulted in a concentration-dependent reduction in hepatoma cell growth as measured by MTT (3-(4,5-dimethylthiazol- 2-yl)-2,5-diphenyltetrazolium bromide) assay. This effect was accompanied by a marked increase in the proportion of S cells as analyzed by flow cytometry. In addition, human hepatoma SMMC-7721 cells treated with GlcNH2-HCl resulted in the induction of apoptosis as assayed qualitatively by agarose gel electrophoresis. NAG could not inhibit the proliferation of SMMC-7721 cells. GlcNH2-HCl exhibited antitumor activity against Sarcoma 180 in Kunming mice at dosage of 125-500 mg/kg, dose of 250 mg/kg being the best. GlcNH2-HCl at dose of 250 mg/kg could enhance significantly the thymus index, and spleen index and could promote T lymphocyte proliferation induced by ConA. The antitumor effect of GlcNH2-HCl is probably host-mediated and cytocidal. 展开更多

AIMTo compare the efficacy and safety of cold snare polypectomy (CSP) and hot forceps biopsy (HFB) for diminutive colorectal polyps.METHODSThis prospective, randomized single-center clinical trial included consecutive patients &#x02265; 20 years of age with diminutive colorectal polyps 3-5 mm from December 2014 to October 2015. The primary outcome measures were en-bloc resection (endoscopic evaluation) and complete resection rates (pathological evaluation). The secondary outcome measures were the immediate bleeding or immediate perforation rate after polypectomy, delayed bleeding or delayed perforation rate after polypectomy, use of clipping for bleeding or perforation, and polyp retrieval rate. Prophylactic clipping after polyp removal wasn&#x02019;t routinely performed.RESULTSTwo hundred eight patients were randomized into the CSP (102), HFB (106) and 283 polyps were evaluated (CSP: 148, HFB: 135). The en-bloc resection rate was significantly higher with CSP than with HFB [99.3% (147/148) vs 80.0% (108/135), P &#x0003c; 0.0001]. The complete resection rate was significantly higher with CSP than with HFB [80.4% (119/148) vs 47.4% (64/135), P &#x0003c; 0.0001]. The immediate bleeding rate was similar between the groups [8.6% (13/148) vs 8.1% (11/135), P = 1.000], and endoscopic hemostasis with hemoclips was successful in all cases. No cases of perforation or delayed bleeding occurred. The rate of severe tissue injury to the pathological specimen was higher HFB than CSP [52.6% (71/135) vs 1.3% (2/148), P &#x0003c; 0.0001]. Polyp retrieval failure was encountered CSP (7), HFB (2).CONCLUSIONCSP is more effective than HFB for resecting diminutive polyps. Further long-term follow-up study is required. 展开更多

Background:Forefoot strike(FFS) and rearfoot strike(RFS) runners differ in their kinematics,force loading rates,and joint loading patterns,but the timing of their muscle activation is less clear.Methods:Forty recreational and highly trained runners ran at four speeds barefoot and shod on a motorized treadmill. "Barefoot" runners wore thin,five-toed socks and shod runners wore neutral running shoes.Subjects were instructed to run comfortably at each speed with no instructions about foot strike patterns.Results:Eleven runners landed with an FFS when barefoot and shod and eleven runners landed with an RFS when barefoot and shod.The 18remaining runners shifted from an FFS when barefoot to an RFS when shod(shifters).Shod shifters ran with a lower stride frequency and greater stride length than all other runners.All FFS runners landed with more plantarflexed ankles and more vertical lower legs at the beginning of stance compared to RFS runners.FFS runners activated their plantarflexor muscles 1 1%earlier and 10%longer than RFS runners.Conclusion:This earlier and longer relative activation of the plantarrlexors likely enhances the capacity for the passive structures of the foot and ankle to store elastic energy,and may also enhance the performance of the active muscle by increasing the storage of elastic strain energy in the cross-bridaes and activated thin. 展开更多

Purpose: To test the effectiveness of sitting surfaces with varied amounts of stability on muscle activity and energy expenditure.Methods: Using a within-participants repeated measures design, 11 healthy young-adult females(age = 20.0 ± 1.8 years) were measured using indirect calorimetry to assess energy expenditure, and electromyography to assess muscular activation in trunk and leg musculature under 3different sitting surfaces: flat-firm surface, air-filled cushion, and a stability ball. Data were analyzed using repeated measures analysis of variance with follow-up pairwise contrasts used to determine the specific effects of sitting surface on muscle activation and energy expenditure.Results: Significantly greater energy expenditure was recorded for the stability ball(p = 0.01) and the cushion(p = 0.03) over the flat surface(10.4% and 9.6% greater, respectively), with no differences between the ball and the cushion. Both the ball and the cushion produced higher tibialis anterior activation over the flat surface(1.09 and 0.63 root-mean-square millivolts(RMSmv), respectively), while the stability ball produced higher soleus activity over both cushion and flat surfaces(3.97 and 4.24 RMSmv, respectively). Additionally, the cushion elicited higher adductor longus activity over the ball and flat surfaces(1.76 and 1.81 RMSmv, respectively), but no trunk musculature differences were revealed.Conclusion: Compliant surfaces resulted in higher levels of muscular activation in the lower extremities facilitating increased caloric expenditure.Given the increasing trends in sedentary careers and the increases in obesity, this is an important finding to validate the merits of active sitting facilitating increased caloric expenditure and muscle activation. 展开更多

The effects of rearing temperature on white muscle and hepatic phosphofructokinase (PFK), pyruvate kinase (PK), lactate dehydrogenase (LDH), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were examined in fingerlings of blue tilapia, Oreochromis aureus. The experiment was conducted for 14 weeks at temperatures of 18, 22, 26, 30, and 34℃. The activity of the glycolytic enzymes PFK, PK, and LDH in white muscle increased significantly with increase in water temperature. A reverse trend was observed for these enzymes in the liver, except for LDH, which behaved in the same manner as in white muscle. Cytosolic AST and ALT activity increased in both white muscle and liver in response to warm thermal acclimatization, while a reduction in mitochondrial AST and ALT activity was noticed at high temperatures in comparison with those at a lower temperature. 展开更多

AIM: To determine the most frequent etiologies of hepatic epithelioid granulomas, and whether there was an association with chronic hepatitis C virus (HCV). METHODS: Both a retrospective review of the pathol- ogy database of liver biopsies at our institution from 1996 through 2006 as well as data from a prospective study of hepatic fibrosis markers and liver biopsies from 2003 to 2006 were reviewed to identify cases of hepatic epithelioid granulomas. Appropriate charts, liver biopsy slides, and laboratory data were reviewed to determine all possible associations. The diagnosis of HCV was based on a positive HCV RNA. RESULTS: There were 4578 liver biopsies and 36 (0.79%) had at least one epithelioid granuloma. HCV was the most common association. Fourteen patients had HCV, and in nine, there were no concurrent condi- tions known to be associated with hepatic granulomas. Prior interferon therapy and crystalloid substances from illicit intravenous injections did not account for the finding. There were hepatic epithelioid granulomas in 3 of 241 patients (1.24%) with known chronic HCV enrolled in the prospective study of hepatic fibrosis markers. CONCLUSION: Although uncommon, hepatic granu- Iomas may be part of the histological spectrum of chronic HCV. When epithelioid granulomas are found on the liver biopsy of someone with HCV, other clini- cally appropriate studies should be done, but if nothing else is found, the clinician can be comfortable with an HCV association. 展开更多

AIM To define clinical criteria to differentiate eosinophilic gastrointestinal disorder(Eo GD) in the esophagus. METHODS Our criteria were defined based on the analyses of the clinical presentation of eosinophilic esophagitis(Eo E), subepithelial eosinophilic esophagitis(s Eo E) and eosinophilic esophageal myositis(Eo EM), identified by endoscopy, manometry and serum immunoglobulin E levels(s-Ig E), in combination with histological and polymerase chain reaction analyses on esophageal tissue samples.RESULTS In five patients with Eo E, endoscopy revealed longitudinal furrows and white plaques in all, and fixed rings in two. In one patient with s Eo E and four with Eo EM, endoscopy showed luminal compression only. Using manometry, failed peristalsis was observed in patients with Eo E and s Eo E with some variation, while Eo EM was associated with hypercontractile or hypertensive peristalsis, with elevated s-Ig E. Histology revealed the following eosinophils per high-power field values. Eo E = 41.4 ± 7.9 in the epithelium and 2.3 ± 1.5 in the subepithelium; s Eo E = 3 in the epithelium and 35 in the subepithelium(conventional biopsy); Eo EM = none in the epithelium, 10.7 ± 11.7 in the subepithelium(conventional biopsy or endoscopic mucosal resection) and 46.8 ± 16.5 in the muscularis propria(peroral esophageal muscle biopsy). Presence of dilated epithelial intercellular space and downward papillae elongation were specific to Eo E. Eotaxin-3, IL-5 and IL-13 were overexpressed in Eo E.CONCLUSION Based on clinical and histological data, we identified criteria, which differentiated between Eo E, s Eo E and Eo EM, and reflected a different pathogenesis between these esophageal Eo GDs. 展开更多

AIM. Pouchitis develops in ileoanal pouches in up to 50% of patients with ulcerative colitis during the first 10 years after pouch surgery while being rare in patients after proctocolectomy for familial adenomatous polyposis coil (FAP) syndrome. Defensins are major components of the innate immune system and play a significant role in gastrointestinal microbial homeostasis. Pouch defensin and cytokine expression were correlated with states of pouch inflammation to study their role in pouchitis.METHODS: Patients with ulcerative colitis and FAP syndrome were stratified into groups with pouches after surgery, pouches without or with pouchitis. Biopsies from terminal ileum from a healthy intestine or from normal terminal ileum of patients with ulcerative colitis served as controls, mRNA from pouches and controls was analysed for defensin and cytokine expression.RESULTS: Expression of defensins was increased in all pouches immediately after surgery, compared to ileum of controls. Initially, pouches in ulcerative colitis revealed higher defensin expression than FAP pouches. Defensin expression declined in both patient groups and increased again slightly in pouchitis in patients with ulcerative colitis. FAP pouches without pouchitis had strong expression of β-defensin hBD-1, while all other defensins remained at low levels. Cytokine expression in ulcerative colitis pouches was high, while FAP pouches showed moderately elevated cytokines only after surgery.CONCLUSION: Development of pouchitis correlates with decreased defensin expression in ulcerative colitis in addition to high expression of cytokines. The low incidence of pouchitis in FAP pouches correlates with increased expression of hBD-1 β- defensin in association with low cytokine levels. 展开更多

Pat Mora's House of Houses is a collection of memories about a Southwestern Mexican immigrant family. She develops multilayered meanings of the house in terms of psychological, spiritual, and sensory influences on both her private and communal life. She deploys sensory signiflers to portray religious and spiritual memories in a picturesque or performative way. The book reveals that the primacy of the senses as a perceptual device transforms the habitual religious rituals of popular Catholicism into the unconscious. This book shows how sensory perception is engaged in appropriating mystical space/time and interiorizing spiritual objects of family life. Thus, the paper investigates how the sensory agencies contribute to exploring culturally plural ways of experiencing the divine. It also illustrates how Mora's deployment of corporeality is related to her reassessment of femaleness and understanding of a meaning of the divine, which is distinctively embodied through 1o cotidiano. In effect, it focuses on Mora's treatment of the sensible body in connection with spiritual and religious connotations. 展开更多

Over the last few years, the importance of the resident intestinal microbiota in the pathogenesis of several gastrointestinal diseases has been largely investigated. Growing evidence suggest that microbiota can influence gastrointestinal motility. The current working hypothesis is that dysbiosis-driven mucosal alterations induce the production of several inflammatory/immune mediators which affect gut neuro-muscular functions. Besides these indirect mucosal-mediated effects, the present review highlights that recent evidence suggests that microbiota can directly affect enteric nerves and smooth muscle cells functions through its metabolic products or bacterial molecular components translocated from the intestinal lumen. Tolllike receptors, the bacterial recognition receptors, are expressed both on enteric nerves and smooth muscle and are emerging as potential mediators between microbiota and the enteric neuromuscular apparatus. Furthermore, the ongoing studies on probiotics support the hypothesis that the neuromuscular apparatus may represent a target of intervention, thus opening new physiopathological and therapeutic scenarios. 展开更多

AIM:To analyze gastric polypoid lesions in our patient- population with respect to histopathologic features and demographic,clinical,and endoscopic characteristics of patients. METHODS:Clinical records and histopathologic reports of patients with gastric polypoid lesions were analyzed retrospectively.All lesions had been totally removed by either endoscopic polypectomy or hot biopsy forceps.The histopathologic slides were re-evaluated by the same histopathologist. RESULTS:One-hundred and fifty gastric polypoid lesions were identified in 91 patients.There were 53(58 %)women and 38(42 %)men with a median age of 53(range,31 to 82)years.The most frequent presenting symptom was dyspepsia that was observed in 35(38.5 %)patients. Symptoms were mostly related to various associated gastric abnormalities such as chronic gastritis or H pylori infection rather than polypoid lesion itself.Polypoid lesions were commonly located in the antrum followed by cardia.Out of 150 lesions,80(53 %)had the largest dimensions less than or equal to 5 mm and only 7 were pedunculated.The frequencies of hyperplastic polyps,foveolar hyperplasia,and fundic gland polyps were 46 %,18 %,and 14 % respectively. We also detected gastritis varioliformis in 12 specimens, lymphoid follicles in 9,4 adenomatous polyps in 4,polypoid lesions with edematous mucosa in 4,inflammatory polyps in 3,and carcinoid tumor in 1.Adenomatous changes were observed within two hyperplastic polyps and low grade dysplasia in one adenoma.Histopathologic evaluation of the surrounding gastric mucosa demonstrated chronic gastritis in 72(79 %)patients and H pylori infection in 45(49 %). CONCLUSION:Hyperplastic polyps are the mbst frequently encountered subtype of gastric polypoid lesions.They are usually associated with chronic gastritis or H pylori gastritis.Contrary to the previous belief,they may harbour adenomatous changes or dysplastic foci. Therefore,endoscopic polypectomy seems as a safe and fast procedure for both diagnosis and treatment of gastric polypoid lesions at the same session.In addition, edematous mucosa may appear misleadingly as a polypoid lesion in some instances and it can be ruled out only by histopathologic examination. 展开更多
