1Changing role of histopathology in the diagnosis and management of hepatocellular carcinoma显示文摘Hepatocellular carcinoma (HCC) is one of the most common and fatal cancer in the world. HCC frequently presents with advanced disease, has a high recurrence rate and limited treatment options, which leads to very poor prognosis. This warrants urgent improvement in the diagnosis and treatment. Liver biopsy plays very important role in the diagnosis and prognosis of HCC, but with technical advancements and progression in the field of imaging, clinical guidelines have restricted the role of biopsy to very limited situations. Biopsy also has its own problems of needle tract seeding of tumor, small risk of complications, technical and sampling errors along with interpretative errors. Despite this, tissue analysis is often required because imaging is not always specific, limited expertise and lack of advanced imaging in many centers and limitations of imaging in the diagnosis of small, mixed and other variant forms of HCC. In addition, biopsy confirmation is often required for clinical trials of new drugs and targeted therapies. Tissue biomarkers along with certain morphological features, phenotypes and immune-phenotypes that serve as important prognostic and outcome predictors and as decisive factors for therapy decisions, add to the continuing role of histopathology. Advancements in cancer biology and development of molecular classification of HCC with clinic pathological correlation, lead to discovery of HCC phenotypic surrogates of prognostic and therapeutically significant molecular signatures. Thus tissue characteristics and morphology based correlates of molecular subtypes provide invaluable information for management and prognosis. This review thus focuses on the importance of histopathology and resurgence of role of biopsy in the diagnosis, management and prognostication of HCC.Archana Rastogi 2018World Journal of Gastroenterology2018,24,35:17

3Retrograde-viewing device improves adenoma detection rate in colonoscopies for surveillance and diagnostic workup显示文摘AIM:To determine which patients might benefit most from retrograde viewing during colonoscopy through subset analysis of randomized,controlled trial data.METHODS:The Third Eye Retroscope Randomized Clinical Evaluation(TERRACE) was a randomized,controlled,multicenter trial designed to evaluate the efficacy of a retrograde-viewing auxiliary imaging device that is used during colonoscopy to provide a second video image which allows viewing of areas on the proximal aspect of haustral folds and flexures that are difficult to see with the colonoscope's forward view.We performed a post-hoc analysis of the TERRACE data to determine whether certain subsets of the patient population would gain more benefit than others from use of the device.Subjects were patients scheduled for colonoscopy for screening,surveillance or diagnostic workup,and each underwent same-day tandem examinations with standard colonoscopy(SC) and Third Eye colonoscopy(TEC),randomized to SC followed by TEC or vice versa.RESULTS:Indication for colonoscopy was screening in 176/345 subjects(51.0%),surveillance after previous polypectomy in 87(25.2%) and diagnostic workup in 82(23.8%).In 4 subjects no indication was specified.Previously reported overall results had shown a net additional adenoma detection rate(ADR) with TEC of 23.2% compared to SC.Relative risk(RR) of missing adenomas with SC vs TEC as the initial procedure was 1.92(P = 0.029).Post-hoc subset analysis shows additional ADRs for TEC compared to SC were 4.4% for screening,35.7% for surveillance,55.4% for diagnostic and 40.7% for surveillance and diagnostic combined.The RR of missing adenomas with SC vs TEC was 1.11(P = 0.815) for screening,3.15(P = 0.014) for surveillance,8.64(P = 0.039) for diagnostic and 3.34(P = 0.003) for surveillance and diagnostic combined.Although a multivariate Poisson regression suggested gender as a possibly significant factor,subset analysis showed that the difference between genders was not statistically significant.Age,bowel prep quality and withdrawal time did not significantly affect the RR of missing adenomas with SC vs TEC.Mean sizes of adenomas detected with TEC and SC were similar at 0.59 cm and 0.56 cm,respectively(P = NS).CONCLUSION:TEC allows detection of significantly more adenomas compared to SC in patients undergoing surveillance or diagnostic workup,but not in screening patients(ClinicalTrials.gov Identifier:NCT01044732).Peter D Siersema Amit Rastogi Anke M Leufkens Paul A Akerman Kassem Azzouzi Richard I Rothstein Frank P Vleggaar Alessandro Repici Giacomo Rando Patrick I Okolo Olivier Dewit Ana Ignjatovic Elizabeth Odstrcil James East Pierre H Deprez Brian P Saunders Anthony N Kalloo Bradley Creel Vikas Singh Anne Marie Lennon Daniel C DeMarco 2012World Journal of Gastroenterology2012,18,26:6
4Nicotinamide adenine dinucleotide phosphate oxidase activation and neuronal death after ischemic stroke显示文摘Nicotinamide adenine dinucleotide phosphate oxidase(NOX) is a multisubunit enzyme complex that utilizes nicotinamide adenine dinucleotide phosphate to produce superoxide anions and other reactive oxygen species. Under normal circumstances, reactive oxygen species mediate a number of important cellular functions, including the facilitation of adaptive immunity. In pathogenic circumstances, however,excess reactive oxygen species generated by NOX promotes apoptotic cell death. In ischemic stroke, in particular, it has been shown that both NOX activation and derangements in glucose metabolism result in increased apoptosis. Moreover, recent studies have established that glucose, as a NOX substrate, plays a vital role in the pathogenesis of reperfusion injury. Thus, NOX inhibition has the potential to mitigate the deleterious impact of hyperglycemia on stroke. In this paper, we provide an overview of this research,coupled with a discussion of its implications for the development of NOX inhibition as a strategy for the treatment of ischemic stroke. Both inhibition using apocynin, as well as the prospect of developing more specific inhibitors based on what is now understood of the biology of NOX assembly and activation, will be highlighted in the course of our discussion.Jiamei Shen Radhika Rastogi Xiaokun Geng Yuchuan Ding 2019Neural Regeneration Research2019,14,6:6

11Clinical practice of early extubation after liver transplantation显示文摘BACKGROUND: Anesthetic practices such as early tracheal extubation facilitate postoperative recovery. Early extubation after liver transplantation has been adopted by some centers in the recent two decades. No universal clinical guidelines are used and questions remain. This review aimed to address the current status of early extubation after liver transplantation. DATA SOURCES: A literature search of MEDLINE and ISI Web of Knowledge databases was performed using terms such as liver transplantation, early extubation, immediate tracheal extubation fast tracking or fast track anesthesia and postoperative tracheal extubation. Additional papers were identified by a manual search of the references in the key articles. RESULTS: Review of the available literature provided an insight into the definition, evolution, advantages and risks of early extubation, and anesthetic techniques that prompt early extubation in liver transplant patients. Early extubation has proved to be feasible and safe in these patients, but the outcomes are still uncertain. CONCLUSIONS: Early extubation after liver transplantation is feasible, safe and cost-effective in the majority of patients and has been increasingly accepted as an option for conventional postoperative ventilation. Comprehensive and individualized evaluation of the patient's condition before extubation by an experienced anesthesiologist is the cornerstone of success Understanding of its effect on the outcome remains incomplete In the future, additional trials are required to establish universal early extubation guidelines and to determine its benefits for patients and practitioners.Vaibhav Rastogi 2012Hepatobiliary & Pancreatic Diseases International2012,11,6:3
12Determination of flavonoids,polyphenols and antioxidant activity of Tephrosia purpurea:a seasonal study显示文摘OBJECTIVE:Tephrosia purpurea(Linn.) Pers.is widely used in traditional medicine to treat liver disorders,febrile attacks,enlargement and obstruction of liver,spleen,and kidney.In the present study,investigations were carried out to determine the seasonal impact on the content of flavonoid glycosides and on antioxidant activities so as to identify the optimal time of harvesting.METHODS:The plant materials were collected in different seasons during 2013-2014.Air-dried,powdered plant materials were extracted with 95%ethanol and ethanokwater(1:1) by ultrasound-assisted extraction process.Their chemical composition in terms of total polyphenol and flavonoid contents(TPCs and TFCs) was determined using modified colorimetric Folin-Ciocalteu method and aluminum chloride colorimetric assay respectively.To determine the in vitro antioxidant activity,diphenyl-picryl hydrazyl(DPPH) radical-scavenging assay and total antioxidant capacity by phosphomolybdate antioxidant assay were carried out.High-performance liquid chromatography(HPLC)/photo-diode array(PDA) analysis was used to quantify the flavonoid glycosides in the samples collected in different seasons.Correlation studies were also carried out between antioxidant activities and TPCs.RESULTS:The highest TPC and TFC were found to be in the 95%ethanolic extract of the August sample and the lowest in the 50%hydro-alcoholic extract of the plant sample collected in winter season.It was observed that in both the assays used to determine the antioxidant activity,the 95%ethanolic extracts in all the seasons showed a higher activity than their respective 50%hydroalcoholic extracts with an increase in activity as we go from cold to hot to rainy seasons.Based on correlation analysis,DPPH radical-scavenging activities as well as the spectrophotometrically measured phosphomolybdenum complex were also strongly correlated with TPC of the extracts.The most abundant flavonoid glycoside was quercetin-3-O-rhamnoglucoside in all the seasons.The content of all flavonoids was observed highest in the 95%ethanolic extract of the plant collected in August(TP-3).The 50%hydro-alcoholic extract of the plant collected in December(TP-6) showed the lowest amount of flavonoids and antioxidant activity.CONCLUSION:The findings of this study confirmed that the metabolism and production of flavonoids in T.purpurea are vigorously affected by seasonal factors.Significant differences were observed in the TPC,TFC and flavonoid glycoside composition in the 95%ethanolic as well as 50%hydro-alcoholic extracts of T.purpurea collected in different seasons.Since the 95%ethanolic extract of the August sample(TP-3),which also happens to be its flowering season,exhibited the highest TPC.TFC and antioxidant activities in both DPPH and phosphomolybdate assays as well as contained the highest content of all flavonoids,it could be recommended as the optimal season of harvesting T.purpurea with respect to its pharmaceutically important constituents,i.e.,flavonoids.Madan Mohan Pandey Sayyada Khatoon Subha Rastogi Ajay Kumar Singh Rawat 2016Journal of Integrative Medicine2016,14,6:3
13Bipolar radiofrequency ablation of tibialchondroblastomas: A report of three cases显示文摘Chondroblastoma is a rare benign cartilaginous neoplasm of bone. The recurrence rate is high and complications are frequent following open curettage with bone grafting which is the standard treatment forchondroblastomas. We performed radiofrequency ablation in three cases of tibialchondroblastoma using the bipolar system. One patient experienced residual pain for which repeat ablation was performed. No other complications were observed during follow-up. Radiofrequency ablation may offer an effective alternative for the treatment of selected cases of chondroblastoma. The lesion characteristics which are likely to influence treatment outcome and the advantages offered by the bipolar system are discussed.Prathiba Rajalakshmi Deep N Srivastava Shivanand Gamanagatti Pramod Kumar Julka Sushma Bhatnagar Shishir Rastogi 2012World Journal of Radiology2012,4,7:2
14Recent advances in production,purification and applications of phycobiliproteins显示文摘An obligatory sunlight requirement for photosynthesis has exposed cyanobacteria to different quantity and quality of light. Cyanobacteria can exhibit efficient photosynthesis over broad region(450 to 650 nm) of solar spectrum with the help of brilliantly coloured pigment proteins called phycobiliproteins(PBPs). Besides light-harvesting, PBPs are found to involve in several life sustaining phenomena including photoprotection in cyanobacteria. The unique spectral features(like strong absorbance and fluorescence), proteineous nature and, some imperative properties like hepato-protective, antioxidants, anti-inflammatory and anti-aging activity of PBPs enable their use in food, cosmetics, pharmaceutical and biomedical industries. PBPs have been also noted to show beneficial effect in therapeutics of some disease like Alzheimer and cancer. Such large range of applications increases the demand of PBPs in commodity market. Therefore, the large-scale and coast effective production of PBPs is the real need of time. To fulfil this need, many researchers have been working to find the potential producer of PBPs for the production and purification of PBPs. Results of these efforts have caused the inventions of some novel techniques like mixotrophic and heterotrophic strategies for production and aqueous two phase separation for purification purpose. Overall, the present review summarises the recent findings and identifies gaps in the field of production, purification and applications of this biological and economically important proteins.Ravi Raghav Sonani Rajesh Prasad Rastogi Rutvij Patel Datta Madamwar 2016World Journal of Biological Chemistry2016,7,1:2
