| 2 | Evaluating alternative stem cell hypotheses for adult corneal epithelial maintenance显示文摘In this review we evaluate evidence for three different hypotheses that explain how the corneal epithelium is maintained. The limbal epithelial stem cell(LESC)hypothesis is most widely accepted. This proposes that stem cells in the basal layer of the limbal epithelium, at the periphery of the cornea, maintain themselves and also produce transient(or transit) amplifying cells(TACs). TACs then move centripetally to the centre of the cornea in the basal layer of the corneal epithelium and also replenish cells in the overlying suprabasal layers. The LESCs maintain the corneal epithelium during normal homeostasis and become more active to repair significant wounds. Second, the corneal epithelial stem cell(CESC) hypothesis postulates that, during normal homeostasis, stem cells distributed throughout the basal corneal epithelium, maintain the tissue. According to this hypothesis, LESCs are present in the limbus but are only active during wound healing. We also consider a third possibility, that the corneal epithelium is maintained during normal homeostasis by proliferation of basal corneal epithelial cells without any input from stem cells. After reviewing the published evidence, we conclude that the LESC and CESC hypotheses are consistent with more of the evidence than the third hypothesis, so we do not consider this further. The LESC and CESC hypotheses each have difficulty accounting for one main type of evidence so we evaluate the two key lines of evidence that discriminate between them. Finally, we discuss how lineage-tracing experiments have begun to resolve the debate in favour of the LESC hypothesis. Nevertheless, it also seems likely that some basal corneal epithelial cells can act as long-term progenitors if limbal stem cell function is compromised. Thus, this aspect of the CESC hypothesis may have a lasting impact on our understanding of corneal epithelial maintenance, even if it is eventually shown that stem cells are restricted to the limbus as proposed by the LESC hypothesis. | John D West Natalie J Dorà J Martin Collinson | 2015 | World Journal of Stem Cells2015,7,2: | 6 |
| 3 | Characteristics of gas geochemistry in Yangbajing geothermal field, Tibet显示文摘CO 2 is a main component of gases in the Yangbajing geothermal field, usually higher than 85 in volume; others are N 2, H 2S, H 2, CH 4, etc. Helium R/R a ratios, ranging from 0.14 to 0.46, indicate a crustal component to be dominant in the gases. δ 13C-CO 2 values and δ 34S-H 2S values are in the range -7.72‰--11.33‰ and 0.2‰-8.3‰, respectively. The gases are inferred to mostly derive from the partial melting of the Nyainqentanglha core complex. The gases of shallow and deep reservoirs are distinctive in chemical compositions and δ 34S-H 2S values, which shows their different flowing paths and physical-chemical processes. Sulphur does not approach isotopic equilibrium between H 2S and SO 2- 4 species in both reservoirs. Significance of steam chemical monitoring is also discussed. | Ping Zhao Ji Dor Tingli Liang Jian Jin Haizheng Zhang | 1998 | Chinese Science Bulletin1998,43,21: | 5 |
| 4 | The effects of water flow and temperature on thermal regime around a culvert built on permafrost显示文摘Temperature and water flow through a culvert beneath the Alaska Highway near Beaver Creek,Yukon,were measured at hourly intervals between June and October 2013.These data were used to simulate the effect of the culvert on the thermal regime of the road embankment and subjacent permafrost.A 2-D thermal model of the embankment and permafrost was developed with TEMP/W and calibrated using field observations.Empirical relations were obtained between water temperatures at the entrance to the culvert,flow into the culvert,and water temperatures inside the structure.Water temperatures at the entrance and inside the culvert had a linear relation,while water temperatures inside the culvert and water flow were associated by a logarithmic relation.A multiple linear regression was used to summarize these relations.From this relationship,changes in the flow rate and water temperatures at the entrance of the culvert were simulated to obtain predicted water temperatures in the culvert.The temperatures in the culvert were used in the thermal model to determine their effects on the ground thermal regime near the culvert.Variation of ±10% in water flow rate had no impact on the thermal regime underneath the culvert.Variation of water temperature at the entrance of the culvert had a noticeable influence on the thermal regime.A final simulation was conducted without insulation beneath the culvert.The thaw depth was 30 cm with insulation,and 120 cm without insulation,illustrating the importance of insulation to the ground thermal regime. | Loriane Périer Guy Doré C.R.Burn Loriane Perier Guy Dore C.

| 5 | Anticoagulation in simultaneous pancreas kidney transplantation - On what basis?显示文摘BACKGROUND Despite technical refinements,early pancreas graft loss due to thrombosis continues to occur.Conventional coagulation tests(CCT)do not detect hypercoagulability and hence the hypercoagulable state due to diabetes is left untreated.Thromboelastogram(TEG)is an in-vitro diagnostic test which is used in liver transplantation,and in various intensive care settings to guide anticoagulation.TEG is better than CCT because it is dynamic and provides a global hemostatic profile including fibrinolysis.AIM To compare the outcomes between TEG and CCT(prothrombin time,activated partial thromboplastin time and international normalized ratio)directed anticoagulation in simultaneous pancreas and kidney(SPK)transplant recipients.METHODS A single center retrospective analysis comparing the outcomes between TEG and CCT-directed anticoagulation in SPK recipients,who were matched for donor age and graft type(donors after brainstem death and donors after circulatory death).Anticoagulation consisted of intravenous(IV)heparin titrated up to a maximum of 500 IU/h based on CCT in conjunction with various clinical parameters or directed by TEG results.Graft loss due to thrombosis,anticoagulation related bleeding,radiological incidence of partial thrombi in the pancreas graft,thrombus resolution rate after anticoagulation dose escalation,length of the hospital stays and,1-year pancreas and kidney graft survival between the two groups were compared.RESULTS Seventeen patients who received TEG-directed anticoagulation were compared against 51 contemporaneous SPK recipients(ratio of 1:3)who were anticoagulated based on CCT.No graft losses occurred in the TEG group,whereas 11 grafts(7 pancreases and 4 kidneys)were lost due to thrombosis in the CCT group(P=0.06,Fisher’s exact test).The overall incidence of anticoagulation related bleeding(hematoma/gastrointestinal bleeding/hematuria/nose bleeding/re-exploration for bleeding/post-operative blood transfusion)was 17.65%in the TEG group and 45.10%in the CCT group(P=0.05,Fisher’s exact test).The incidence of radiologically confirmed partial thrombus in pancreas allograft was 41.18%in the TEG and 25.50%in the CCT group(P=0.23,Fisher’s exact test).All recipients with partial thrombi detected in computed tomography(CT)scan had an anticoagulation dose escalation.The thrombus resolution rates in subsequent scan were 85.71%and 63.64%in the TEG group vs the CCT group(P=0.59,Fisher’s exact test).The TEG group had reduced blood product usage{10 packed red blood cell(PRBC)and 2 fresh frozen plasma(FFP)}compared to the CCT group(71 PRBC/10 FFP/2 cryoprecipitate and 2 platelets).The proportion of patients requiring transfusion in the TEG group was 17.65%vs 39.25%in the CCT group(P=0.14,Fisher’s exact test).The median length of hospital stay was 18 days in the TEG group vs 31 days in the CCT group(P=0.03,Mann Whitney test).The 1-year pancreas graft survival was 100%in the TEG group vs 82.35%in the CCT group(P=0.07,log rank test)and,the 1-year kidney graft survival was 100%in the TEG group vs 92.15%in the CCT group(P=0.23,log tank test).CONCLUSION TEG is a promising tool in guiding judicious use of anticoagulation with concomitant prevention of graft loss due to thrombosis,and reduces the length of hospital stay. | Jeevan Prakash Gopal Frank JMF Dor Jeremy S Crane Paul E Herbert Vassilios E Papalois Anand SR Muthusamy | 2020 | World Journal of Transplantation2020,10,7: | 2 |
| 6 | Synchronous electrogastrographic and manometric study of the stomach as an esophageal substitute显示文摘AIM: To investigate the electric and contractile mechanisms involved in the deranged function of the transposed stomach in relation to the course of the symptoms and the changes in contractile and electrical parameters over time.METHODS: Twenty-one patients after subtotal esophagectomy and 18 healthy volunteers were studied.Complaints were compiled by using a questionnaire, and a symptom score was formed. Synchronous electrogastrography and gastric manometry were performed in the fasting state and postprandially.RESULTS: Eight of the operated patients were symptomfree and 13 had symptoms. The durations of the postoperative periods for the symptomatic (9.1±6.5 mo)and the asymptomatic (28.3±8.8 mo) patients were significantly different. The symptom score correlated negatively with the time that had elapsed since the operation. The percentages of the dominant frequency in the normogastric, bradygastric and tachygastric ranges differed significantly between the controls and the patients.A significant difference was detected between the power ratio of the controls and that of the patients. The occurrence of tachygastria in the symptomatic and the symptom-free patients correlated negatively both with the time that had elapsed and with the symptom score. There was a significant increase in motility index after feeding in the controls, but not in the patients. The contractile activity of the stomach increased both in the controls and in the symptom-free patients. In contrast, in the group of symptomatic patients, the contractile activity decreased postprandially as compared with the fasting state.CONCLUSION: The patients' post-operative complaints and symptoms change during the post-operative period and correlate with the parameters of the myoelectric and contractile activities of the stomach. Tachygastria seems to be the major pathogenetic factor involved in the contractile dysfunction. | Ferenc Izbéki Tibor Wittmann Sándor (O|')dor Balázs Botos (A|')ron Altorjay | 2005 | World Journal of Gastroenterology2005,11,8: | 2 |
