1Expression profile of cholecystokinin type-A receptor in gallbladder cancer and gallstone disease显示文摘BACKGROUND:Regulatory peptide receptors have attracted the interest of oncologists as a new promising approach for cancer pathology,imaging and therapy.Although cholecystokinin (CCK) is a potent modulator of gallbladder contractility and plays a potential role in pancreatic carcinogenesis through CCK type-A receptor (CCKAR),its role in gallbladder cancer (GBC) is still unknown and immunohistochemical detection of CCKAR in the gallbladder has not yet been reported.This novel case-control study aimed to investigate the expression profile of CCKAR in GBC and gallstone disease (GSD).METHODS:This study included 162 samples of gallbladder:94 from GBC and 68 from GSD.Expression of CCKAR was analyzed by immunohistochemistry and immunoblotting.The results were statistically correlated with disease history including age,sex,presence of gallstone,stage and differentiation.RESULTS:CCKAR was positive in 30/68 (44.1%) of GSD and 72/94 (76.6%) of GBC samples.Fifty-one of the 72 (70.8%) CCKAR-positive GBC samples showed over-expression.Interestingly,consistent results also appeared in the immunoblotting study.CONCLUSIONS:CCKAR expression was significantly increased in GBC compared to GSD.Moreover,CCKAR expression was associated with the degree of tumor differentiation,i.e.,less expression in poorly-differentiated tumors.Thus,it has future prognostic and therapeutic implications in the management of GBC.Rajani Rai Mallika Tewari Mohan Kumar Tej Bali Singh Hari S Shukla 2011Hepatobiliary & Pancreatic Diseases International2011,10,4:7
2Species Richness, Diversity and Density of Understory Vegetation along Disturbance Gradients in the Himalayan Conifer Forest显示文摘We investigated whether species richness, diversity and density of understory herbaceous plants differed along logging(gap) and grazing(primarily by cattle) disturbance gradients, and sought to identify drivers of richness, diversity and density of understory vegetation of logged sites. A factorial experiment was conducted in the mixed conifer forest of Gidakom in Western Bhutan. Levels of the logging treatment included small(0.15 – 0.24 ha), medium(0.25 – 0.35 ha) and large(0.36 – 1.31 ha) gaps. The grazing treatment included grazed(primarily by cattle) and ungrazed(where herbivores were excluded by a fence) plots nested within each gap. Data were collected from 12 gaps(4 replicates at each level of logging) using the point intercept method. Shannon Weaver Diversity and Margalef's indices were used to estimate species diversity and describe species richness, respectively. Soil samples were analyzed for pH and nutrients. The interaction effect of logging and grazing was significant(p≤0.001) only on species diversity. Relative to ungrazed areas, species diversity was significantly higher(0.01≤p≤0.05) in medium grazed gaps. Under grazed conditions, soil P was negatively correlated with gap size and species diversity. While species diversity was positivelycorrelated(0.01≤p≤0.05) with soil N in grazed plots species richness was positively correlated(0.001≤p≤0.01) with soil N in ungrazed plots. Relative density of Yushania microphylla and Carex nubigena were higher under ungrazed conditions. Our study suggests that the combined effect of cattle grazing and logging results in higher species diversity of understory vegetation in medium and grazed gaps in mixed conifer forests of Bhutan,whereas increase or decrease in relative density of major species is determined primarily by the independent effects of grazing and logging. From management perspective, forest managers must refrain from creating large gaps to avoid loss of nutrients(mainly P and N), which may eventually affect tree regeneration. Managers intending to maintain understory vegetation diversity must consider the combined effects of grazing and logging, ensuring low to moderate grazing pressure.Kesang WANGCHUK András DARABANT Prem Bahadur RAI Maria WURZINGER Werner ZOLLITSCH Georg GRATZER 2014Journal of Mountain Science2014,11,5:2
