2Comparative study of outcomes following laparoscopic Roux-en-Y gastric bypass and sleeve gastrectomy in morbidly obese patients: A case control study显示文摘AIM To compare the impact of laparoscopic Roux-en-Y gastric bypass(LRYGB) and laparoscopic sleeve gastrectomy(LSG) on weight loss and obesity related comorbidities over two year follow-up via case control study design.METHODS Forty patients undergoing LRYGB, who completed their two year follow-up were matched with 40 patients undergoing LSG for age, gender, body mass index and presence of type 2 diabetes mellitus(T2DM). Data of these patients was retrospectively reviewed to compare the outcome in terms of weight loss and improvement in comorbidities, i.e., T2 DM, hypertension(HTN), obstructive sleep apnea syndrome(OSAS), hypothyroidism and gastroesophageal reflux disease(GERD).RESULTS Percentage excess weight loss(EWL%) was similar in LRYGB and LSG groups at one year follow-up(70.5% vs 66.5%, P = 0.36) while it was significantly greater for LRYGB group after two years as compared to LSG group(76.5% vs 67.9%, P = 0.04). The complication rate after LRYGB and LSG was similar(10% vs 7.5%,P = 0.99). The median duration of T2 DM and mean number of oral hypoglycemic agents were higher in LRYGB group than LSG group(7 years vs 5 years and 2.2 vs 1.8 respectively, P < 0.05). Both LRYGB and LSG had significant but similar improvement in T2 DM, HTN, OSAS and hypothyroidism. However, GERD resolved in all patients undergoing LRYGB while it resolved in only 50% cases with LSG. Eight point three percent patients developed new-onset GERD after LSG.CONCLUSION LRYGB has better outcomes in terms of weight loss two years after surgery as compared to LSG. The impact of LRYGB and LSG on T2 DM, HTN, OSAS and hypothyroidism is similar. However, LRYGB has significant resolution of GERD as compared to LSG.Harshit Garg Pratyusha Priyadarshini Sandeep Aggarwal Samagra Agarwal Rachna Chaudhary 2017World Journal of Gastrointestinal Endoscopy2017,9,4:7
3Minimizing transmission loss using inspired ant colony optimization and Markov Chain Monte Carlo in underwater WSN environment显示文摘In Underwater Wireless Sensor Networks(UWSNs),the most important challenging issues are propagation delay,high error probability,high latency,high communication cost,limited bandwidth,limited memory,low packet delivery ratio,and transmission loss.In our proposed work,the various efforts are taken to minimize the propagation delay and transmission loss during data transmission in an underwater environment.A hybrid mechanism is implemented to improve energy efficiency for faster data transmission in underwater WSN.In the underwater environment of acoustic channel condition,propagation delay and transmission loss lead to high complexity in accessing the information and also it is difficult to obtain the Channel Status Information(CSI).To address this problem,Ant Colony Optimization(ACO)routing with Markov Chain Monte Carlo(MCMC)algorithm is used and to capture the transmission loss in the MCMC approach,CSI Forecast Prediction(FP)algorithm is used.The experimental simulations are evaluated by utilizing the performance evaluation metrics such as Transmission Loss,Probability Density Function,Average Delay and Throughput.From the simulation results it is evident that the proposed algorithm,ACO-MCMC has recorded the minimum transmission loss,increase in probability density function,minimum average delay and maximum throughput of the network when compared to the existing algorithms.Raj Priyadarshini R Sivakumar N 2019Journal of Ocean Engineering and Science2019,4,4:7
4A Distributed Mechanism for Handling of Adaptive/Intelligent Selfish Misbehaviour at MAC Layer in Mobile Ad Hoc Networks显示文摘Medium access control(MAC) protocols such as IEEE 802.11 are used in wireless networks for sharing of the wireless medium.The random nature of the protocol operation together with the inherent difficulty of monitoring in the open poses significant challenges.All nodes are expected to comply with the protocol rules.But,some nodes in order to gain greater benefits misbehave by not complying with the rules.One such selfish misbehavior is waiting for smaller back-off intervals when compared to the other nodes in the same subnet.Such selfish misbehavior is being tackled in this paper.A diagnosis scheme and a penalty scheme are being proposed for overcoming such selfish-misbehavior at MAC layer of mobile ad hoc networks which could be extended to other types of networks also.Raja Gunasekaran Vaidheyanathan Rhymend Uthariaraj Uamapathy Yamini Rajagopalan Sudharsan Selvaraj Sujitha Priyadarshini 2009Journal of Computer Science & Technology2009,24,3:4
5Chemopreventive effect of apple and berry fruits against colon cancer显示文摘Colon cancer arises due to the conversion of precancerous polyps(benign)found in the inner lining of the colon.Prevention is better than cure,and this is very true with respect to colon cancer.Various epidemiologic studies have linked colorectal cancer with food intake.Apple and berry juices are widely consumed among various ethnicities because of their nutritious values.In this review article,chemopreventive effects of these fruit juices against colon cancer are discussed.Studies dealing with bioavailability,in vitro and in vivo effects of apple and berry juices are emphasized in this article.A thorough literature survey indicated that various phenolic phytochemicals present in these fruit juices have the innate potential to inhibit colon cancer cell lines.This review proposes the need for more preclinical evidence for the effects of fruit juices against different colon cancer cells,and also strives to facilitate clinical studies using these juices in humans in large trials.The conclusion of the review is that these apple and berry juices will be possible candidates in the campaign against colon cancer.Saravana Kumar Jaganathan Muthu Vignesh Vellayappan Gayathri Narasimhan Eko Supriyanto Dyah Ekashanti Octorina Dewi Aqilah Leela T Narayanan Arunpandian Balaji Aruna Priyadarshini Subramanian Mustafa Yusof 2014World Journal of Gastroenterology2014,20,45:3
6Rice GLUTATHIONE PEROXIDASE1-mediated oxidation of bZIP68 positively regulates ABA-independent osmotic stress signaling显示文摘Osmotic stress caused by drought and high salinity is a significant environmental threat that limits plant growth and agricultural yield. Redox regulation plays an important role in plant stress responses, but the mechanisms by which plants perceive and transduce redox signals are still underexplored. Here, we report a critical function for the thiol peroxidase GPX1 in osmotic stress response in rice, where it serves as a redox sensor and transducer. GPX1 is quickly oxidized upon exposure to osmotic stress and forms an intramolecular disulfide bond, which is required for the activation of bZIP68, a VRE-like basic leucine zipper (bZIP) transcription factor involved in the ABA-independent osmotic stress response pathway. The disulfide exchange between GPX1 and bZIP68 induces homo-tetramerization of bZIP68 and thus positively regulates osmotic stress response by regulating osmotic-responsive gene expression. Furthermore, we discovered that the nuclear translocation of GPX1 is regulated by its acetylation under osmotic stress. Taken together, our findings not only uncover the redox regulation of the GPX1-bZIP68 module during osmotic stress but also highlight the coordination of protein acetylation and redox signaling in plant osmotic stress responses.Heng Zhou Feng Zhang Fengchao Zhai Ye Su Ying Zhou Zhenglin Ge Priyadarshini Tilak Jürgen Eirich Iris Finkemeier Ling Fu Zongmin Li Jing Yang Wenbiao Shen Xingxing Yuan Yanjie Xie 2022Molecular Plant2022,15,4:2

8Prediction and optimization of machining forces using oxley’s predictive theory and RSM approach during machining of WHAs显示文摘Tungsten heavy alloys have come up as one of the best alternatives for high density fragmenting devices and armor piercing ammunition.Machining is mandatory for obtaining the final shapes of such kind of ammunitions.However,due to high density and elastic stiffness of WHAs,cutting forces will be higher than for most of the metals and alloys;thus,making the machining operation challenging.The machining variable,namely,cutting force components are significantly influenced by the cutting parameters.This paper makes use of Oxley’s predictive analytical model in conjunction with Johnson-Cook constitutive equation to predict forces under different speed and feed combinations during machining of 95 W tungsten heavy alloy.The cutting forces,so predicted by Ml,are considered as input data for the optimization of cutting parameters(cutting speed and feed)using Response Surface Method(RSM).Chithajalu Kiran Sagar Tarun Kumar Amrita Priyadarshini Amit Kumar Gupta 2019Defence Technology(防务技术)2019,15,6:1
