| 1 | Effect of sodium arsenite on spermatogenesis, plasma gonadotrophins and testosterone in rats显示文摘Aim:To investigate the effect of arsenic on spermatogenesis.Methods:Mature(4 months old)Wistar rats were intraperitoneally administered sodium arsenite at doses of 4,5 or 6mg·kg^-1·day^-1 for 26 days.Different varieties of germ cells at stage Ⅶ seminiferous epithelium cycle,namely,type A spermatogonia(ASg),preleptotene spermatocytes(pLSc),midpachytene spermatocytes(mPSc) and step 7 spermatids(7Sd) were quantitatively evaluated, along with radioimmunoassay of plasma follicle-stimulating hormone(FSH),lutuneizing hormone(LH),testosterone and assessment of the epididymal sperm count.Results:In the 5 and 6 mg/kg groups,there were significant dosedependent decreases in the accessory sex organ weights,epididymal sperm count and plasma concentrations of LH,FSH and testosterone with massive degeneration of all the germ cells at stage Ⅶ,The changes were insignificant in the 4 mg/kg group.Conclusion:Arsenite has a suppressive influence on spermatogenesis and gonadotrophin and testosterone release in rats. | Mahitosh Sarkar Gargi Ray Chaudhuri Aloke Chattopadhyay Narendra Mohan Biswas | 2003 | Asian Journal of Andrology2003，5，1： | 24 |
| 2 | Outcome of gall bladder polypoidal lesions detected by transabdominal ultrasound scanning: A nine year experience显示文摘AIM: To determine the outcome of polypoidal lesions within the gall bladder (PLG) diagnosed by trans-abdominal scanning.METHODS: A nine-year (1993-2002) retrospective casenote review of all patients who underwent ultrasound scanning after referral to a single Upper GI Surgeon at a District General Hospital was conducted. Patients who were diagnosed with a PLG were included in our study. A database was constructed and patient details, investigations including ultrasound scan (USS) findings, treatment and histology and final diagnosis were recorded. RESULTS: Twenty-three (out of 651) patients were diagnosed pre-operatively by USS to have a polyp-likegall bladder lesion (PLG). Post cholecystectomy histological examination revealed 12 gallstones, 7 cholesterol polyps, 3 adenocarcinomas within polyps and 1 normal gall bladder. The specificity of USS in the diagnosis of PLG was 92.3%. All the true polyps were malignant. Overall USS had 66.66% sensitivity and 100% specificity in the pre-operative suspicion of malignancy. Using size greater than 10 mm as measured on USS as a cut-off, we find 100% sensitivity and 86.95% specificity with a positive predictive value of 50% in the diagnosis of malignancy in PLG.CONCLUSION: A large number of PLG are in fact calculi within diseased gall bladder. In cases of gall bladder polyps more then 10 mm in size on USS further imaging (crosssectional and/or EUS) is indicated prior to surgery. This will help in the optimal management of patients and avoid histological surprises. | D Chattopadhyay R Lochan S Balupuri BR Gopinath KS Wynne | 2005 | World Journal of Gastroenterology2005，11，14： | 23 |
| 3 | The development of Terminalia chebula Retz.(Combretaceae) in clinical research显示文摘Medicinal plants are part and parcel of human society to combat diseases from the dawn of civilization.Terminalia chebula Retz.(Fam.Combretaceae),is called the‘King of Medicine??in Tibet and is always listed at the lop of the list of‘Ayurvedic Materia Medica??because of its extraordinary power of healing.The whole plant possesses high medicinal value and traditionally used for the treatment of various ailments for human beings.Some of the folklore people used this plant in the treatment of asthma,sore throat,vomiting,hiccough,diarrhea,dysentery,bleeding piles,ulcers,gout,heart and bladder diseases.The plant has been demonstrated to possess multiple pharmacological and medicinal activities,such as antioxidant,antimicrobial,antidiabetic,hepatoprotective,anti-inflammatory,antimutagenic,antiproliferative,radioprotective,cardioprotective,antiarthritic,anticaries,gastrointestinal motility and wound healing activity.But no systematic updated information on the therapeutic effectiveness of Terminalia chebula,a popular herbal remedy in India and South-East Asia has so far been reported.This review highlights an updated information particularly on the phytochemistry and various pharmacological and medicinal properties of Terminalia chebula Retz.and some of its isolated compounds,along with their safety evaluation.This may provide incentive for proper evaluation of the plant as medicinal agent against the human diseases and also to bridge the lacunae in the existing literature and future scope which may offer immense opportunity for researchers engaged in validation of the traditional claims and development of safe and effective botanical medicine. | Anwesa Bag Subir Kumar Bhattacharyya Rabi Ranjan Chattopadhyay | 2013 | Asian Pacific Journal of Tropical Biomedicine2013，3，3： | 17 |

| 5 | Portal biliopathy显示文摘Biliary ductal changes are a common radiological finding in patients with portal hypertension, however only a small percentage of patients (5%-30%) develop symptomatic bile duct obstruction. The exact pathogenesis is not clear, but an involvement of factors such as bile duct compression by venous collaterals, ischemia, and infection is accepted by most authors. Although endoscopic retrograde cholangiopancrea- tography was used to define and diagnose this condition, magnetic resonance cholangiopancreatography is currently the investigation of choice for diagnosing this condition. Treatment is indicated only for symptomatic cases. Portosystemic shunts are the treatment of choice for symptomatic portal biliopathy. In the majority of patients, the changes caused by biliopathy resolve after shunt surgery, however, 15%-20% patients require a subsequent bilio-enteric bypass or endoscopic management for persistent biliopathy. There is a role for endoscopic therapy in patients with bile duct stones, cholangitis or when portosystemic shunt surgery is not feasible. | Somnath Chattopadhyay Samiran Nundy | 2012 | World Journal of Gastroenterology2012，18，43： | 9 |

| 7 | Euler-Euler CFD modeling of fluidized bed:Influence of specularity coefficient on hydrodynamic behavior显示文摘Euler-Euler two-fluid model is used to simulate the hydrodynamics of gas-solid flow in a bubbling fluidized bed with Geldert B particles where the solid property is calculated by applying the kinetic theory of granular flow(KTGF).Johnson and Jackson wall boundary condition is used for the particle phase,and different amount of slip between particle and wall is given by varying the specularity coefficient(φ) from0 to 1.The simulated particle velocity,granular temperature and particle volume fraction are compared to investigate the effect of different wall boundary conditions on the hydrodynamic behavior.Some of the results are also compared with the available experimental data from the literature.It was found that the model predictions are sensitive to the specularity coefficient.The hydrodynamic behavior deviated significantly for φ = 0 and φ = 0.01 with maximum deviation found at φ = 0 i.e.free-slip condition.However,the overall bed height predicted by all the conditions is similar. | Chanchal Loha Himadri Chattopadhyay Pradip K.Chatterjee | 2013 | Particuology2013，11，6： | 7 |
| 8 | Curcumin reverses T cell-mediated adaptive immune dysfunctions in tumor-bearing hosts显示文摘Immune dysfunction is well documented during tumor progression and likely contributes to tumor immune evasion.CD81 cytotoxic T lymphocytes(CTLs)are involved in antigen-specific tumor destruction and CD41 T cells are essential for helping this CD81 T cell-dependent tumor eradication.Tumors often target and inhibit T-cell function to escape from immune surveillance.This dysfunction includes loss of effector and memory T cells,bias towards type 2 cytokines and expansion of T regulatory(Treg)cells.Curcumin has previously been shown to have antitumor activity and some research has addressed the immunoprotective potential of this plant-derived polyphenol in tumor-bearing hosts.Here we examined the role of curcumin in the prevention of tumor-induced dysfunction of T cell-based immune responses.We observed severe loss of both effector and memory T-cell populations,downregulation of type 1 and upregulation of type 2 immune responses and decreased proliferation of effector T cells in the presence of tumors.Curcumin,in turn,prevented this loss of T cells,expanded central memory T cell(TCM)/effector memory T cell(TEM)populations,reversed the type 2 immune bias and attenuated the tumor-induced inhibition of T-cell proliferation in tumor-bearing hosts.Further investigation revealed that tumor burden upregulated Treg cell populations and stimulated the production of the immunosuppressive cytokines transforming growth factor(TGF)-b and IL-10 in these cells.Curcumin,however,inhibited the suppressive activity of Treg cells by downregulating the production of TGF-b and IL-10 in these cells.More importantly,curcumin treatment enhanced the ability of effector T cells to kill cancer cells.Overall,our observations suggest that the unique properties of curcumin may be exploited for successful attenuation of tumor-induced suppression of cell-mediated immune responses. | Sankar Bhattacharyya Dewan Md Sakib Hossain Suchismita Mohanty Gouri Sankar Sen Sreya Chattopadhyay Shuvomoy Banerjee Juni Chakraborty Kaushik Das Diptendra Sarkar Tanya Das Gaurisankar Sa | 2010 | Cellular & Molecular Immunology2010，7，4： | 7 |
| 9 | Effect of coefficient of restitution in Euler-Euler CFD simulation of fluidized-bed hydrodynamics显示文摘Collision between particles plays an important role in determining the hydrodynamic characteristics of gas-solid flow in a fluidized bed.In the present work,earlier work(Loha,Chattopadhyay.& Chatterjee,2013) was extended to study the effect of the elasticity of particle collision on the hydrodynamic behavior of a bubbling fluidized bed filled with 530-μm particles.The Eulerian-Eulerian two-fluid model was used to simulate the hydrodynamics of the bubbling fluidized bed.where the solid-phase properties were calculated by applying the kinetic theory of granular flow.To investigate the effect of the elasticity of particle collision,different values of the coefficient of restitution were applied in the simulation and their effects were studied in detail.Simulations were performed for two different solid-phase wall boundary conditions.No bubble formation was observed for perfectly elastic collision.The bubble formation started as soon as the coefficient of restitution was set below 1.0,and the space occupied by bubbles in the bed increased with a decrease in the coefficient of restitution.Simulation results were also compared with experimental data available in the literature,and good agreement was found for coefficients of restitution of 0.95 and 0.99. | Chanchal Loha Himadri Chattopadhyay Pradip K.Chatterjee | 2014 | Particuology2014，12，4： | 6 |
| 10 | Endovascular management in abdominal visceral arterial aneurysms:A pictorial essay显示文摘Visceral artery aneurysms(VAAs) include aneurysms of the splanchnic circulation and those of the renal artery.Their diagnosis is clinically important because of the associated high mortality and potential complications.Splenic,superior mesenteric,gastroduodenal,hepatic and renal arteries are some of the common arteries affected by VAAs.Though surgical resection and anastomosis still remains the treatment of choice in some of the cases,especially cases involving the proximal arteries,increasingly endovascular treatment is being used for more distal vessels.We present a pictorial review of various intra-abdominal VAAs and their endovascular management. | Manisha Jana Shivanand Gamanagatti Amar Mukund Sujoy Paul Pankaj Gupta Pramod Garg Tushar K Chattopadhyay Peush Sahni | 2011 | World Journal of Radiology2011，3，7： | 5 |

| 13 | 1α,25-dihydroxyvitamin D_(3) prevents DNA damage and restores antioxidant enzymes in rat hepatocarcinogenesis induced by diethylnitrosamine and promoted by phenobarbital显示文摘AIM:To investigate the chemopreventive iffects of 1α,25-dihydroxyvitamin D3 in diethylnitrosamine induced,phenobarbital promoted rat hepatocarcinogenesis.METHODS:The rats were randomly divided into 6 different groups(A-F).Group A,C and E rats received a single intraperitoneal (i.p) injection of diethylnitrosamine (DEN) at a dose of 200 mg/kg body mass in 9 g/L NaCl solution at 4 wk of age ,while group B served as normal vehicle control received normal saline once.After a brief recovery of 2 WK, all the DEN treated rats were given phenobarbital (PB) at 0.5g/L daily in the basal diet till WK 20.Group C was started 4 wk prior to DEN injection and continued thereafter till wk 20 at a dose (os) twice a week.Group E received the treatment of 1α,25-(OH)2D3 at the same dose mentioned as above for 15 wk.The rats in group D and F received 1α,25-(OH)2D3 alone as in group C without DEN injection.RESULTS:The comet assay showed statistically higher mean values for length to width ratios (L:W) of DNA mass and tailed cells (p<0.01;p<0.01 respectively) in DEN treated rats as compared to their normal controls.Continuous supplementation of 1α,25-dihydroxyvitaminD3 showed a significant (p<0.01) decrease in L:W ratio of DNA mass tailed cells.Furthermore,1α,25-(OH)2D3 supplementations elevated the super oxide dismutase (SOD) activety,hepatic malondialdehyde(MDA) levle,reduced glutathione (GSH) and glutathione S-transferase (GST) activety (p<0.01,p<0.01,p<0.05 and p<0.05 respectively).As an endpoint marker histological changes were observed to establish the chemopreventive effects of 1α,25-dihydroxyvitaminD3.CONCLUSION:Supplementations of 1α,25-(OH)2D3 has a marked protection against hepatic nodelogenesis,antioxidant enzymes and DNA damages in DEN induced rat hepatocarcinogenesis promoted by phenobarbital. | Mahendrakumar Chandrasekharappa Banakar Suresh Kanna Paramasivan Mitali Basu Chattopadhyay Subrata Datta Prabir Chakraborty Malay Chatterjee Kalaiselvi Kannan Elayaraja Thygarajan | 2004 | World Journal of Gastroenterology2004，10，9： | 5 |
| 14 | Effect of pouring temperature on cooling slope casting of semi-solid Al-Si-Mg alloy显示文摘Present trend of semi-solid processing is directed towards rheocasting route which allows manufacturing of near-net-shape cast components directly from the prepared semi-solid slurry. Generation of globular equi-axed grains during solidification of rheocast components, compared to the columnar dendritic structure of conventional casting routes, facilitates the manufacturing of components with improved mechanical properties and structural integrity. In the present investigation, a cooling slope has been designed and indigenously fabricated to produce semi solid slurry of Al-Si-Mg (A356) alloy and successively cast in a metallic mould. The scope of the present work discusses about development of a numerical model to simulate the liquid metal flow through cooling slope using Eulerian two-phase flow approach and to investigate the effect of pouring temperature on cooling slope semi-solid slurry generation process. The two phases considered in the present model are liquid metal and air. Solid fraction evolution of the solidifying melt is tracked at different locations of the cooling slope, following Schiel s equation. The continuity equation, momentum equation and energy equation are solved considering thin wall boundary condition approach. During solidification of the liquid metal, a modified temperature recovery scheme has been employed taking care of the latent heat release and change of fraction of liquid. The results obtained from simulations are compared with experimental findings and good agreement has been found. | Prosenjit Das Sudip K.

| 16 | Physiological Basis of Stagnant Flooding Tolerance in Rice显示文摘Stagnant flooding(SF) is an important constraint which prolonges partial submergence damages of rice plants and reduces grain yield. Due to the heterogeneity in flood-prone ecosystem, many different types of traditional rice varieties are being grown by the farmers. The local landraces adapted to extreme in water availability could be the sources of new gene(s) which would be utilized to improve the adaptability of rice to SF with high yield. The main goal of this study is to identify new genetic resources tolerant to SF based on morpho-physiological traits. A total of 16 rice varieties were selected after initial screening from more than 400 rice varieties which were collected from eastern states of India. The increase rate of plant height was higher under SF compared to control, whereas no such trend was observed in the increment rate of aboveground total dry weight and culm dry weight. Area of aerenchyma gas spaces per tiller increased whereas root oxidase activity decreased under SF. The reduction of root oxidase activity, leaf area, and leaf dry weight was higher in susceptible varieties under SF compared to control. Stability index for different grain yield and yield attributes revealed that the impact of SF differed among different varieties. Correlation coefficient studies among different parameters taking stability index showed significant association with the grain yield. Based on the findings, it was concluded that maintenance of equivalent panicle weight and panicle number, plant height and harvest index at the maturity stage, leaf area, leaf and culm dry weights, root oxidase activity and tiller numbers at the flowering stage under SF compared to control help the plant to counteract the adverse effects of SF. | Sandhya R.KUANAR Anuprita RAY Santosh K.SETHI Krishnendu CHATTOPADHYAY Ramani K.SARKAR | 2017 | Rice science2017，24，2： | 4 |
| 17 | Healing property of the Piper betel phenol, allylpyrocatechol against indomethacin-induced stomach ulceration and mechanism of action显示文摘AIM: To evaluate the protective activity of allylpyrocatechol (APC), the major antioxidant constituent of Piper betel, against the indomethacin-induced stomach ulceration in the rat model and correlates with its antioxidative and mucin protecting properties. METHODS: Male Sprague-Dawley rats were divided into five groups. Normal control rats (group Ⅰ) were given the vehicle oral dose of gum acacia in distilled water (1 mL per rat); ulcerated control and treated rats (groups Ⅱ-Ⅴ) were given a single dose of indomethacin (30 mg/kg body wt.); group Ⅱ rats were sacrificed 4 h after indomethacin administration; groups Ⅲ-Ⅴ rats were given the vehicle (1 mL per rat) or APC (2 mg/kg body wt.) or misoprostol (1.43 μg/kg body wt.) once daily by oral intubation for 7 d starting from 4 h after the indomethacin administration. After 7 d, the stomach tissues were excised for histological examination and biochemical analysis. RESULTS: Treatment with APC (2 mg/kg body wt per day) and misoprostol (1.43 μg/kg body wt per day) for 7 d could effectively heal the stomach ulceration as revealed from the ulcer index and histopathological studies. Compared to the zero day ulcerated group, treatment with APC and misoprostol reduced the ulcer index by 93.4% and 85.4% respectively (P < 0.05). Both APC and misoprostol accelerated ulcer healing observed in natural recovery (P < 0.05), their respective healing capacities not being significantly different. The healing capacities of APC and misoprostol could be attributed to their antioxidant activity as well as the ability to enhancethe mucin content of the gastric tissues. Compared to the ulcerated untreated rats, those treated with APC and misoprostol showed near normal MDA levels, while the protein levels were 86% and 78% of the normal value respectively (P < 0.05). Likewise, both APC and misoprostol increased the SOD, catalase, and mucin levels significantly (P < 0.05), the effect of APC being better. CONCLUSION: APC can protect indomethacin-induced gastric ulceration due to its antioxidative and mucin protecting properties. | S Bhattacharya D Banerjee AK Bauri S Chattopadhyay SK Bandyopadhyay | 2007 | World Journal of Gastroenterology2007，13，27： | 4 |
| 18 | Nitric oxide mediated Staphylococcus aureus pathogenesis and protective role of nanoconjugated vancomycin显示文摘Objective:To investigate the relation between fruit seeds,plants residuals and appendicitis. Methods:Among cases that underwent appendectomy,the appendicitis cases having fruit seeds and undigested plant residuals in their etiology were examined retrospectively.Also, histopathological features,age,sex,and parameters of morbidity and mortality were used. Results:Fruit seed was found in one case(0.05%) with presence of pus in appendix lumen, undigested plant residuals in 7 cases(0.35%).It was determined that there were appendix inflammation in 2 of the plant residuals cases,while there were obstruction and lymphoid hyperplasia in the appendix lumen of 5 cases.No mortality was observed.Conclusions:The ratio of acute appendicitis caused by plants is minimal among all appendectomised patients, but avoidence of eating undigested fruit seeds and chewing plants well may help to prevent appendicitis. | Subhankari Prasad Chakraborty Santanu Kar Mahapatra Sumanta Kumar Sahu Sourav Chattopadhyay Panchanan Pramanik Somenath Roy | 2011 | Asian Pacific Journal of Tropical Biomedicine2011，1，2： | 4 |

| 20 | Gene expression profile of esophageal cancer in North East India by cDNA microarray analysis显示文摘AIM: To identify alterations in genes and molecular functional pathways in esophageal cancer in a high incidence region of India where there is a widespread use of tobacco and betel quid with fermented areca nuts. METHODS: Total RNA was isolated from tumor and matched normal tissue of 16 patients with esophageal squamous cell carcinoma. Pooled tumor tissue RNA was labeled with Cy3-dUTP and pooled normal tissue RNA was labeled with Cy5-dUTP by direct labeling method. The labeled probes were hybridized with human 10K cDNA chip and expression profiles were analyzed by Genespring GX V 7.3 (Silicon Genetics). RESULTS: Nine hundred twenty three genes were differentially expressed. Of these, 611 genes were upregulated and 312 genes were downregulated. Using stringent criteria (P ≤ 0.05 and ≥ 1.5 fold change), 127 differentially expressed genes (87 upregulated and 40 downregulated) were identified in tumor tissue. On the basis of Gene Ontology, four different molecular functional pathways (MAPK pathway, G-protein coupled receptor family, ion transport activity, and serine or threonine kinase activity) were most significantly upregulated and six different molecular functional pathways (structural constituent of ribosome, endopeptidase inhibitor activity, structural constituent of cytoskeleton, antioxidant activity, acyl group transferase activity, eukaryotic translation elongation factor activity) were most significantly downregulated. CONCLUSION: Several genes that showed alterations in our study have also been reported from a high incidence area of esophageal cancer in China. This indicates that molecular profiles of esophageal cancer in these two different geographic locations are highly consistent. | Indranil Chattopadhyay Sujala Kapur Joydeep Purkayastha Rupkumar Phukan Amal Kataki Jagadish Mahanta Sunita Saxena | 2007 | World Journal of Gastroenterology2007，13，9： | 3 |
