| 1 | Differentiating Crohn's disease from intestinal tuberculosis显示文摘Differentiating Crohn's disease(CD) and intestinal tuberculosis(ITB) has remained a dilemma for most of the clinicians in the developing world, which are endemic for ITB, and where the disease burden of inflammatory bowel disease is on the rise. Although, there are certain clinical(diarrhea/hematochezia/perianal disease common in CD; fever/night sweats common in ITB), endoscopic(longitudinal/aphthous ulcers common in CD; transverse ulcers/patulous ileocaecal valve common in ITB), histologic(caseating/confluent/large granuloma common in ITB; microgranuloma common in CD), microbiologic(positive stain/culture for acid fast-bacillus in ITB), radiologic(long segment involvement/comb sign/skip lesions common in CD; necrotic lymph node/contiguous ileocaecal involvement common in ITB), and serologic differences between CD and ITB, the only exclusive features are caseation necrosis on biopsy, positive smear for acid-fast bacillus(AFB) and/or AFB culture, and necrotic lymph node on cross-sectional imaging in ITB. However,these exclusive features are limited by poor sensitivity, and this has led to the development of multiple multi-parametric predictive models. These models are also limited by complex formulae, small sample size and lack of validation across other populations. Several new parameters have come up including the latest Bayesian meta-analysis, enumeration of peripheral blood T-regulatory cells, and updated computed tomography based predictive score. However, therapeutic anti-tubercular therapy(ATT) trial, and subsequent clinical and endoscopic response to ATT is still required in a significant proportion of patients to establish the diagnosis. Therapeutic ATT trial is associated with a delay in the diagnosis of CD, and there is a need for better modalities for improved differentiation and reduction in the need for ATT trial. | Saurabh Kedia Prasenjit Das Kumble Seetharama Madhusudhan Siddhartha Dattagupta Raju Sharma Peush Sahni Govind Makharia Vineet Ahuja | 2019 | World Journal of Gastroenterology2019,25,4: | 19 |
| 2 | Biodiversity effects and transgressive overyielding显示文摘Aims The potential for mixtures of plant species to produce more biomass than every one of their constituent species in monoculture is still controversially discussed in the literature.Here we tested how this socalled transgressive overyielding is affected by variation between and within species in monoculture yields in biodiversity experiments.Methods We use basic statistical principles to calculate expected maximum monoculture yield in a species pool used for a biodiversity experiment.Using a real example we show how between-and withinspecies variance components in monoculture yields can be obtained.Combining the two components we estimate the importance of sampling bias in transgressive overyielding analysis.Important Findings The net biodiversity effect(difference between mixture and average monoculture yield)needed to achieve transgressive overyielding increases with the number of species in a mixture and with the variation between constituent species in monoculture yields.If there is no significant variation between species,transgressive overyielding should not be calculated using the best monoculture,because in this case the difference between this species and the other species could exclusively reflect a sampling bias.The sampling bias decreases with increasing variation between species.Tests for transgressive overyielding require replicated species’monocultures.However,it can be doubted whether such an emphasis on monocultures in biodiversity experiments is justified if an analysis of transgressive overyielding is not the major goal. | Bernhard Schmid Andy Hector Prasenjit Saha Michel Loreau | 2008 | Journal of Plant Ecology2008,1,2: | 5 |
| 3 | In-Situ Hydrothermal Synthesis of Bi–Bi2O2CO3 Heterojunction Photocatalyst with Enhanced Visible Light Photocatalytic Activity显示文摘Bismuth containing nanomaterials recently received increasing attention with respect to environmental applications because of their low cost, high stability and nontoxicity. In this work, Bi–Bi_2O_2CO_3 heterojunctions were fabricated by in-situ decoration of Bi nanoparticles on Bi_2O_2CO_3 nanosheets via a simple hydrothermal synthesis approach. X-ray diffraction(XRD), scanning electron microscopy(SEM), transmission electron microscopy(TEM) and high-resolution TEM(HRTEM) were used to confirm the morphology of the nanosheet-like heterostructure of the Bi–Bi_2O_2CO_3 composite. Detailed ultrafast electronic spectroscopy reveals that the in-situ decoration of Bi nanoparticles on Bi_2O_2CO_3 nanosheets exhibit a dramatically enhanced electron-hole pair separation rate, which results in an extraordinarily high photocatalytic activity for the degradation of a model organic dye, methylene blue(MB) under visible light illumination. Cycling experiments revealed a good photochemical stability of the Bi–Bi_2O_2CO_3 heterojunction under repeated irradiation. Photocurrent measurements further indicated that the heterojunction incredibly enhanced the charge generation and suppressed the charge recombination of photogenerated electron-hole pairs. | Prasenjit Kar Tuhin Kumar Maji Ramesh Nandi Peter Lemmens Samir Kumar Pal | 2017 | Nano-Micro Letters2017,9,2: | 3 |
| 4 | Plasma cathepsin L:A prognostic marker for pancreatic cancer显示文摘AIM:To assess the prognostic significance of cathepsin L,a cysteine protease that degrades the peri-tumoral tissue,in patients with pancreatic cancer.METHODS:Plasma samples from 127 pancreatic cancer patients were analyzed for cathepsin L levels by ELISA.Out of these patients,25 underwent surgeryand their paraffin-embedded tissue was analyzed for cathepsin L expression by immunohistochemistry.Survival of patients and clinicopathological parameters was correlated with cathepsin L expression in plasma and tissue using appropriate statistical analysis.RESULTS:The mean(±SD)cathepsin L in plasma samples of pancreatic cancer patients was 5.98±2.5ng/m L that was significantly higher compared to the levels in healthy controls(3.83±0.45)or chronic pancreatitis patients(3.97±1.06).Using ROC curve,a cut-off level of 5.0 ng/m L was decided for survival analysis.Elevated plasma levels of cathepsin L were found to be associated with poor prognosis(P=0.01)in multivariate analysis.The plasma levels of the protease decreased after surgery.Though no significant correlation was seen between plasma and tissue expression of this protease,a trend did emerge that high cathepsin L expression in tissue correlated with its high levels in plasma.CONCLUSION:Cathepsin L levels in plasma of pancreatic cancer patients may be used as a potential prognostic marker for the disease. | Nidhi Singh Prasenjit Das Surabhi Gupta Vikas Sachdev Siddhartha Srivasatava Siddhartha Datta Gupta Ravindra Mohan Pandey Peush Sahni Shyam S Chauhan Anoop Saraya | 2014 | World Journal of Gastroenterology2014,20,46: | 2 |

| 13 | Load-dependent indentation behavior ofβ-SiAlON andα-silicon carbide显示文摘A comparative study was carried out on the load-dependent indentation behavior with respect to hardness and induced cracks ofβ-SiAlON andα-silicon carbide ceramics.It is observed that silicon carbide(SiC)exhibits lower transition load,early cracking and severely crushed indentation sites,whereasβ-SiAlON shows higher transition load and damage-free indentation zone even at the maximum applied load(294.19 N).Crack density is higher forα-SiC with comparison toβ-SiAlON at each load.SiC exhibits both main and secondary radial types of cracking from low indentation load(0.98 N).Cracks are often associated with branching at higher load(>9.80 N)forα-SiC.β-SiAlON exhibits cracks which are mainly radial types initiated at 4.90 N load.These opposing behaviors ofβ-SiAlON andα-SiC are attributed to their difference in hardness,toughness,and brittleness index.Higher brittleness ofα-SiC results in early and severe cracking around its indentations.β-SiAlON shows less cracking due to its lower brittleness and higher toughness.The increased size of indentation-induced cracks ofα-SiC is higher than that ofβ-SiAlON due to the rapid crack propagation inα-SiC with transgranular fracture behavior. | Prasenjit BARICK Dulal Chandra JANA Bhaskar Prasad SAHA | 2013 | Journal of Advanced Ceramics2013,2,2: | 1 |
