1全球变化下地表反照率研究进展显示文摘地表反照率表征地球表面对太阳辐射的反射能力,决定着地表与大气之间辐射能量的分配过程,是影响地球气候系统的关键变量。在全球变化日益突出的今天,地表反照率与全球变化的相互影响机制已经成为地球科学研究领域的热点问题之一。地表反照率的细微变化,会影响到地气系统的能量收支平衡,进而引起区域以至全球气候变化。详细介绍地表反照率影响因素、研究方法等方面的最新研究进展,并从全球变化的角度阐述地表反照率的研究动态及其研究方向。肖登攀 陶福禄 Moiwo Juana P 2011地球科学进展2011,26,11:57
2Role of endoscopic ultrasound in the diagnosis of pancreatic cancer显示文摘Endoscopic ultrasonography(EUS) with or without fine needle aspiration has become the main technique for evaluating pancreatobiliary disorders and has proved to have a higher diagnostic yield than positron emission tomography,computed tomography(CT) and transabdominal ultrasound for recognising early pancreatic tumors.As a diagnostic modality for pancreatic cancer,EUS has proved rates higher than 90%,especially for lesions less than 2-3 cm in size in which it reaches a sensitivity rate of 99% vs 55% for CT.Besides,EUS has a very high negative predictive value and thus EUS can reliably exclude pancreatic cancer.The complication rate of EUS is as low as 1.1%-3.0%.New technical developments such as elastography and the use of contrast agents have recently been applied to EUS,improving its diagnostic capability.EUS has been found to be superior to the recent multidetector CT for T stagingwith less risk of overstaying in comparison to both CT and magnetic resonance imaging,so that patients are not being ruled out of a potentially beneficial resection.The accuracy for N staging with EUS is 64%-82%.In unresectable cancers,EUS also plays a therapeutic role by means of treating oncological pain through celiac plexus block,biliary drainage in obstructive jaundice in patients where endoscopic retrograde cholangiopancreatography is not affordable and aiding radiotherapy and chemotherapy.Juana Gonzalo-Marin Juan Jose Vila Manuel Perez-Miranda 2014World Journal of Gastrointestinal Oncology2014,6,9:6
3Laparoscopic sleeve gastrectomy:More than a restrictive bariatric surgery procedure?显示文摘Sleeve gastrectomy(SG) is a restrictive bariatric surgery technique that was first used as part of restrictive horizontal gastrectomy in the original Scopinaro type biliopancreatic diversion. Its good results as a single technique have led to a rise in its use, and it is currently the second most performed technique worldwide. SG achieves clearly better results than other restrictive techniques and is comparable in some aspects to the Roux-en-Y gastric bypass, the current gold standard in bariatric surgery. These benefits have been associated with different pathophysiologic mechanisms unrelated to weight loss such as increased gastric emptying and intestinal transit, and activation of hormonal mechanisms such as increased GLP-1 hormone and decreased ghrelin. The aim of this review was to highlight the salient aspects of SG regarding its historical evolution, pathophysiologic mechanisms, main results, clinical applications and perioperative complications.David Benaiges Antonio Más-Lorenzo Albert Goday José M Ramon Juan J Chillarón Juan Pedro-Botet Juana A Flores-Le Roux 2015World Journal of Gastroenterology2015,21,41:6
4为胃的倒空和活动性评估的电的 bioimpedance 和另外的技术显示文摘 The aim of this article is to identify non-invasive, inexpensive, highly sensitive and accurate techniques for evaluating and diagnosing gastric diseases. In the case of the stomach, there are highly sensitive and specific methods for assessing gastric motility and emptying (GME). However, these methods are invasive, expensive and/or not technically feasible for all clinicians and patients. We present a summary of the most relevant international information on non-invasive methods and techniques for clinically evaluating GME. We particularly emphasize the potential of gastric electrical bioimpedance (EBI). EBI was initially used mainly in gastric emptying studies and was essentially abandoned in favor of techniques such as electrogastrography and the gold standard, scintigraphy. The current research evaluating the utility of gastric EBI either combines this technique with other frequently used techniques or uses new methods for gastric EBI signal analysis. In this context, we discuss our results and those of other researchers who have worked with gastric EBI. In this review article, we present the following topics: (1) a description of the oldest methods and procedures for evaluating GME; (2) an explanation of the methods currently used to evaluate gastric activity; and (3) a perspective on the newest trends and techniques in clinical and research GME methods. We conclude that gastric EBI is a highly effective non-invasive, easy to use and inexpensive technique for assessing GME.María Raquel Huerta-Franco Miguel Vargas-Luna Juana Berenice Montes-Frausto Corina Flores-Hernández Ismael Morales-Mata 2012World Journal of Gastrointestinal Pathophysiology2012,3,1:5
5Effect of psychological stress on gastric motility assessed by electrical bio-impedance显示文摘AIM:To evaluate gastric motility using electrical bioimpedance(EBI) and gastric changes as a result of stress induced by psychological tests.METHODS:A group of 57 healthy women,aged 40-60 years,was recruited,and a clinical history and physical examination were performed.The women were free from severe anxiety,chronic or acute stress,severe depression,mental diseases and conditions that affect gastric activity.The women were evaluated under fasting conditions,and using a four-electrode configuration,the gastric signals were obtained through a BIOPAC MP-150 system.The volunteers were evaluated using the following paradigm:basal state,recording during the Stroop Test,intermediate resting period,recording during the Raven Test,and a final resting period.We analyzed the relative areas of the frequency spectrum:A1(1-2 cpm),A2(2-4 cpm),A3(4-8 cpm),and A4(8-12 cpm),as well as the median of area A2 + A3.The data were analyzed by an autoregressive method using a Butterworth filter with MatLab and Origin.Analysis of variance(ANOVA) and Friedman ANOVA(for nonparametric variables) were performed;in addition,pairs of groups were compared using the T dependent and Wilcoxon T tests.RESULTS:The results of the main values of area A2 were not significantly different comparing the five steps of the experimental paradigm.Nevertheless,there was a tendency of this A2 region to decrease during the stress tests,with recuperation at the final resting step.When an extended gastric region was considered(1-4 cpm),significant differences with the psychological stress tests were present(F = 3.85,P = 0.005).The A3 region also showed significant changes when the stress psychological tests were administered(F = 7.25,P < 0.001).These differences were influenced by the changes in the adjacent gastric region of A2.The parameter that we proposed in previous studies for the evaluation of gastric motility by electrical bio-impedance(EBI) was the median of the area under the region from 2 to 8 cpm(A2 + A3).The mean values of these frequencies(median of the A2 + A3 area) with the stress test showed significant changes(F = 5.5,P < 0.001).The results of the WilcoxonT test for the A4 area parameter,which is influenced by the breathing response,changed significantly during the Raven stress test(P < 0.05).CONCLUSION:We confirm that the gastric response to acute psychological stress can be evaluated by short-term EBI.María Raquel Huerta-Franco Miguel Vargas-Luna Juana Berenice Montes-Frausto Ismael Morales-Mata Lorena Ramirez-Padilla 2012World Journal of Gastroenterology2012,18,36:5
6Coexistence of papillary thyroid microcarcinoma and mucosa-associated lymphoid tissue lymphoma in a context of Hashimoto's thyroiditis显示文摘Papillary thyroid cancer(PTC)represents 80%-85%of thyroid cancer and its prevalence has been rising in the last decades.Primary thyroid lymphoma(PTL)accounts for 3%of extranodal lymphomas and about 5%of thyroid malignancies,having a prevalence of one or two cases per million people.Mucosa-Associated Lymphoid Tissue lymphoma represents approximately30%of PTL.Both entities have an indolent course and a very good prognosis.Diagnosis is made by ultrasound and fine needle aspiration(FNA)or surgery specimen pathology.They have also been associated with Hashimoto’s thyroiditis(HT),but pathogenesis and its links remains to be known.Treatment remains controversial and surgery is generally accepted in cases of disease limited to thyroid,as the present.Patients with thyroid nodules should be observed and followed.If there is an enlargement by ultrasound or clinical symptoms,FNA should be performed promptly.Patients with HT deserve additional surveillance,since this condition is associated with both PTC and PTL.In this case,the management with surgery and radioactive iodine ablation therapy was effective for both entities.Patients with thyroid nodules should be properly evaluated with ultrasound and thyroid function tests.If there is an enlargement of the neck,reported by symptoms or ultrasound,it requires further investigation.HT is associated to both PTC and PTL so if the enlargement of the nodules is on this context additional tests such as FNA should be performed.In this case,the patient was managed with surgery and radioactive iodine ablation therapy and it was effective for both entities.Saul Levy-Blitchtein Stefany Plasencia-Rebata Domingo Morales Luna Juana del Valle Mendoza 2016Asian Pacific Journal of Tropical Medicine2016,9,8:5

8地下水位对农业用水量变化响应的模拟研究显示文摘我国北方地区农业用水占实际取水总量的80%以上,地表水资源匮乏,地下水成为除降水之外的唯一灌溉水源。农业用水与地下水位的变化密切相关,被认为是引起地下水位持续下降的最大诱因。因此,研究地下水动态只有与农业用水结合才更有意义。本研究将DSSAT和MODFLOW两个不同尺度模型耦合,将作物用水与地下水直接建立关系,屏蔽了复杂的包气带水分运动过程,模型达到了很高的精度。通过对华北山前平原区2000年和2001年的模拟分析表明,农业用水节水28.36%,即减少抽取地下水118.75mm的情况下,才能停止本地区地下水位下降。胡玉昆 王玉坤 Juana Paul-moiwo 2009农业网络信息2009,,2:4

10A study of the temporomandibular joint during bruxism显示文摘A finite element model of the temporomandibular joint(TMJ)and the human mandible was fabricated to study the effect of abnormal loading,such as awake and asleep bruxism,on the articular disc.A quasilinear viscoelastic model was used to simulate the behaviour of the disc.The viscoelastic nature of this tissue is shown to be an important factor when sustained(awake bruxism)or cyclic loading(sleep bruxism)is simulated.From the comparison of the two types of bruxism,it was seen that sustained clenching is the most detrimental activity for the TMJ disc,producing an overload that could lead to severe damage of this tissue.María S Commisso Javier Martínez-Reina Juana Mayo 2014International Journal of Oral Science2014,6,2:3
11Impact of Land-use Patterns on Distributed Groundwater Recharge and Discharge——A Case Study of Western Jilin,China显示文摘The impact of land-use on distributed groundwater recharge and discharge in the western Jilin (WJ) was analyzed in this study. WJ is a transitional, semi-arid zone with a fragile, hydrological closed ecosystem in the Songhua River Basin (SRB). The research tool includes a seamlessly linked MODFLOW, WetSpass, the Seepage packages, and ArcGIS. The model calibration showed good agreement between simulated water table elevation and measured water table depths, while predicted groundwater discharge zones showed strong correlations with field occurrences of drainage systems and wetlands. Simulated averages for distributed recharge, water table elevation and groundwater drawdown were 377.42mm/yr, 194.43m, and 0.18m respectively. Forest vegetation showed the highest recharge, followed by ag- ricultural farmlands, while open-water and other drainage systems constituted groundwater exit zones. When present land-use conditions were compared with the hypothetical natural pre-development scenario, an overall loss of ground- water recharge (24.09mm/yr) was observed, which for the project area is 18.05×108m3. Groundwater abstraction seemed to be the cause of water table drawdown, especially in the immediate vicinities of the supply wells. An important issue of the findings was the ability of the hypothetical forest vegetation to protect, and hence sustain aquifer reserves and dependent ecosystems. The profound data capture capability of ArcGIS makes it particularly useful in spa- tio-temporal hydroecological modeling.Moiwo Juana PAUL 2006Chinese Geographical Science2006,16,3:3
12Karst subzone division in vertical cycle zone and its significance显示文摘Vertical cycle karst zone has been studied for more than 100 years, however karst subzones in the zone have never been divided and affected depth of CO2 from rainwater in the zone has never been studied. On the basis of field observation, survey and chemical analysis, the difference of karst processes indicated by CaCO3 and pH values in fine and loose sedimentary strata as well as limestone strata, and the vertical cycle zone ascertained by predecessors can be divided into three subzones, that is, the upper first subzone, characterized by unsaturated water solution and strong dissolution processes, the middle second subzone, characterized by supersaturated water solution and precipitation, and the lower third subzone, characterized by unstable water solution and weak dissolution or weak precipitation. The three subzones can indicate the vertical CO2 cycle. In fine and loose sediment strata, the bottom of the first subzone is the lower boundary strongly influenced by CO2 from rainwater, soil and air; all CO2 from rainwater, soil and air is almost exhausted in the second subzone. In the early developmental period of karst process in limestone strata, karst funnels and vertical caves do not form, vertical seeping of rainwater and soil water is very slow, and CO2 from soil, rainwater and air almost can reach the third subzone, but in the middle and late developmental periods, karst funnels and vertical caves occur, CO2 from soil, rainwater and air can reach deep seasonal change zone and horizontal cycle zone and quicken development of karst morphology. Deep karst morphology near groundwater level under vertical cycle zone develops better in the middle and late periods of karst process.ZHAO Jingbo CHEN Baoqun YUE Yingli DU Juana 2006Journal of Geographical Sciences2006,16,4:3
13Is glucose-6-phosphate dehydrogenase deficiency more prevalent in Carrion's disease endemic areas in Latin America?显示文摘Glucose-6-phosphate dehydrogenase(G6PD) is a cytoplasmic enzyme with an important function in cell oxidative damage prevention.Erythrocytes have a predisposition towards oxidized environments due to their lack of mitochondria,giving G6 PD a major role in its stability.G6 PD deficiency(G6PDd) is the most common enzyme deficiency in humans:it affects approximately 400 million individuals worldwide.The overall G6 PDd allele frequency across malaria endemic countries is estimated to be 8%.corresponding to approximately 220 million males and 133 million females.However,there are no reports on the prevalence of G6 PDd in Andean communities where bartonellosis is prevalent.Fernando Mazulis Claudia Weilg Carlos Alva-Urcia Maria J.Pons Juana del Valle Mendoza 2015Asian Pacific Journal of Tropical Medicine2015,8,12:2
