1Reoperation for early postoperative complications after gastric cancer surgery in a Chinese hospital显示文摘AIM:To investigate the occurrence of postoperative complications of gastric cancer surgery,and analyze the potential causes of reoperation for early postoperative complications. METHODS:A total of 1639 patients who underwent radical or palliative gastrectomies for gastric cancer were included in the study.The study endpoint was the analysis of postoperative complications in inpatients. RESULTS:About 31%of patients had early postoperative complications,and complications of infection occurred most frequently.Intra-abdominal hemorrhage and anastomotic leak were the main causes of reoperation,which accounted for about 2.2%.Mortality was 11.1%in the reoperation group,but was only 0.8%in other patients.The duration of postoperative stay in hospital was significantly longer and the total expenditure was markedly higher in the patients who underwent reoperation(P<0.001).There was no significant association of any available factors in this study with the high rate of reoperation.CONCLUSION:Reoperation significantly increases the mortality rate and raises the burden of the surgical unit.More prospective studies are required to explore the potential risk factors.Birendra Kumar Sah 2010World Journal of Gastroenterology2010,16,1:23
2Identification of EST–SSRs and molecular diversity analysis in Mentha piperita显示文摘EST sequences of Mentha piperita available in the public domain(NCBI) were exploited to develop SSR markers. A total of 1316 ESTs were assembled into 155 contigs and 653 singletons and of these, 110 sequences were found to contain 130 SSRs, with a frequency of1 SSR/3.4 kb. Dinucleotide repeat SSRs were most frequent(72.3%) with the AG/CT(43.8%)repeat motif followed by AT/AT(16.2%). Primers were successfully designed for 68SSR-containing sequences(62.0%). The 68 primers amplified 13 accessions of M. piperita and 54 produced clear amplicons of the expected size. Of these 54, 33(61%) were found to be polymorphic among M. piperita accessions, showing from 2 to 4 alleles with an average of2.33 alleles/SSR, and the polymorphic information content(PIC) value varied between 0.13 and 0.51(average 0.25). All the amplified SSRs showed transferability among four different species of Mentha, with a highest in Mentha arvensis(87.0%) and minimum in Mentha citrata(37.0%). The newly developed SSRs markers were found to be useful for diversity analysis, as they successfully differentiated among species and accessions of Mentha.Birendra Kumar Umesh Kumar Hemant Kumar Yadav 2015The Crop Journal2015,3,4:14

6Multiobjective optimization of friction welding of UNS S32205 duplex stainless steel显示文摘The present study is to optimize the process parameters for friction welding of duplex stainless steel(DSS UNS S32205).Experiments were conducted according to central composite design.Process variables,as inputs of the neural network,included friction pressure,upsetting pressure,speed and burn-off length.Tensile strength and microhardness were selected as the outputs of the neural networks.The weld metals had higher hardness and tensile strength than the base material due to grain refinement which caused failures away from the joint interface during tensile testing.Due to shorter heating time,no secondary phase intermetallic precipitation was observed in the weld joint.A multi-layer perceptron neural network was established for modeling purpose.Five various training algorithms,belonging to three classes,namely gradient descent,genetic algorithm and LevenbergeM arquardt,were used to train artificial neural network.The optimization was carried out by using particle swarm optimization method.Confirmation test was carried out by setting the optimized parameters.In conformation test,maximum tensile strength and maximum hardness obtained are 822 MPa and 322 Hv,respectively.The metallurgical investigations revealed that base metal,partially deformed zone and weld zone maintain austenite/ferrite proportion of 50:50.P.M.AJITH Birendra Kumar BARIK P.SATHIYA S.ARAVINDAN 2015Defence Technology(防务技术)2015,11,2:3
7Effect of potassium on soil conservation and productivity of maize/cowpea based crop rotations in the north-west Indian Himalayas显示文摘Plots under conservation tillage may require higher amount of potassium(K) application for augmenting productivity due to its stratification in upper soil layers, thereby reducing K supplying capacity in a medium or long-term period. To test this hypothesis, a field experiment was performed in 2002-2003 and 2006-2007 to study the effect of K and several crop rotations on yield, water productivity, carbon sequestration, grain quality, soil K status and economic benefits derived in maize(Zea mays L)/cowpea(Vigna sinensis L.) based cropping system under minimum tillage(MT). All crops recorded higher grain yield with a higher dose of K(120 kg K2 O ha-1) than recommended K(40 kg K2 O ha-1). The five years' average yield data showed that higher K application(120 kg K2 O ha-1) produced 16.4%(P<0.05)more maize equivalent yield. Cowpea based rotation yielded 14.2%(P<0.05) higher production than maize based rotation. The maximum enhancement was found in cowpea-mustard rotation. Relationship between yield and sustainable indices revealed that only agronomic efficiency of fertilizer input was significantly correlated with yield. Similarly, higherdoses of K application not only increased the water use efficiency(WUE) of all crops, but also reduced runoff and soil loss by 16.5% and 15.8% under maize and 23.3% and 19.7% under cowpea cover, respectively. This study also revealed that on an average 16.5% of left over carbon input contributed to soil organic carbon(SOC). Here, cowpea based rotation with the higher K application increased carbon sequestration in soil. Potassium fertilization also significantly improved the nutritional value of harvested grain by increasing the protein content for maize(by 9.5%) and cowpea(by 10.6%). The oil content in mustard increased by 5.0% and 6.0% after maize and cowpea, respectively. Net return also increased with the application of the higher K than recommended K and the trend was similar to yield. Hence, the present study demonstrated the potential yield and profit gains along with resource conservation in the Indian Himalayas due to annual additions of higher amount of K than the recommended dose. The impact of high K application was maximum in the cowpea-mustard rotation.Birendra Nath GHOSH Om Pal Singh KHOLA Ranjan BHATTACHARYYA Kuldeep Singh DADHWAL Prasant Kumar MISHRA 2016Journal of Mountain Science2016,13,4:2
8Effects of in ovo delivered xylo-and mannan-oligosaccharides on growth performance,intestinal immunity,cecal short-chain fatty acids,and cecal microbiota of broilers显示文摘Background:This study investigated a novel in ovo feeding strategy to determine the prebiotic effects of xylo-and mannan-oligosaccharides(XOS and MOS)differing in the degree of polymerization.A total of 192 fertilized eggs were divided into 6 treatment groups:i)normal saline control(NSC),ii)xylotriose(XOS3),iii)xylotetraose(XOS4),iv)mannotriose(MOS3),v)mannotetraose(MOS4),and vi)no injection control(NIC),each containing 4 replicate trays with 8 eggs per replicate.On d 17 of incubation,3 mg of oligosaccharides(except for controls)dissolved in 0.5 mL of 0.85%normal saline were injected into the amnion of Cobb 500 broilers eggs.After hatch,the chicks were raised for 28 d under standard husbandry practices and were fed a commercial broilers diet ad libitum,and samples were collected periodically.Results:The hatchability,growth performance,and relative weights of breast,drumstick,liver,and proventriculus were not different among the treatments(P>0.05).The XOS3 injection increased the total short-chain fatty acid production at d 28 compared with both control groups(P<0.05).The villus height to crypt depth ratio was significantly higher in the XOS4 group than both controls on the hatch day(P<0.01)but were not different among any treatments on d 7 and 28(P>0.05).On the hatch day,the expression level of the CD3 gene(a T cell marker)was increased by XOS3,while the IL-10 gene(a marker of anti-inflammatory cytokine)was reduced by MOS4(P<0.05)compared with both controls.Compared with both controls,XOS3 exhibited a trend of reduction for IL-10(P=0.074).No cytokines or lymphocyte markers were affected by the treatments on d 7(P>0.05),except XOS4 increased IL-4 compared with NSC(P<0.05).The broilers in the MOS4 group had higher operational taxonomic units(OTUs)and had more differentially abundant taxa,including order Lactobacillales and family Leuconostocaceae(P<0.05)than both controls on d 28.The predictive functional profiling indicated that the linoleic acid metabolism pathway was enriched in the cecal microbiota of the XOS3 group compared with both controls(P<0.05).Conclusion:The effects of these XOS and MOS on ileal mucosa and immunity are transient,but the effects on fermentation and cecal microbiota are prolonged,and further research is warranted to determine their use as a gut health promoter in poultry.Amit Kumar Singh Utsav Prakash Tiwari Birendra Mishra Rajesh Jha 2022Journal of Animal Science and Biotechnology2022,13,4:2
9Ore petrography of low-grade siliceous manganese ores from the Bonai-Keonjhar belt, Orissa, India: The influence of mineral-fabric on their beneficiation显示文摘Low grade siliceous manganese ores from the iron ore group of the Bonai-Keonjhar belt, Orissa, India are found mostly in shear zones. The ore characteristics of siliceous manganese ore samples from three differ- ent mines, viz. the Shankar (Barbil OMC lease hold area), the Sone-Patuli (Patmunda, OMM lease hold area), and the Musaghar (Roida, OMDC lease hold area), were studied. These siliceous manganese ores are of three types, respectively: (i) spongy-granular; (ii) massive-mosaic; and (iii) hard-mylonitized. The spongy-gran- ular type contains granular, saccharoidal quartz and the major manganese mineral present is pyrolusite. The second type contains well crystallized quartz and cryptomelane, while the third has cherty, fine grained quartz (mylonite) along with romanechite. All three ores were subjected to physical beneficiation under similar conditions. Both gravity and magnetic separation techniques were employed. The mineral-fabric of the ores has been correlated to the extent of their beneficiation using these physical techniques. Of these three ores only the spongy-granular type responded well to upgrading. The feed with 22% Mn content could be upgraded to 44% with a 28% yield and a 49% recovery. The good response to beneficiation of the spongy- granular sample could be due to the large euhedral crystals of pyrolusite and the friable nature of the sac- charoidal quartz. This study reveals the influence of mineral-fabric on beneficiation of low grade ore, siliceous Mn ore in particular.Mishra Subrat Mohapatra Birendra Kumar Dash Nilima Rao Danda Srinivas 2011Mining Science and Technology2011,21,6:2

11Does testosterone prevent early postoperative complications after gastrointestinal surgery?显示文摘AIM:To investigate the role of sex hormones in the early postoperative complications of gastrointestinal diseases. METHODS:A total of 65 patients who underwent operations for gastric and colorectal diseases(mainly malignant diseases)were included in the study. Peripheral venous blood samples were collected at different times for analysis of estradiol,testosterone and progesterone.The only study endpoint was analysis of postoperative complications. RESULTS:Patients of both sexes were uniform but postoperative complication rate was significantly higher in female patients(P=0.027).There was no significant association of estradiol and progesterone with postoperative complications.Testosterone levels in complicated patients were significantly lower than in uncomplicated patients(P<0.05).Area under the receiver operating characteristic curve showed that a lower value of testosterone was a predictor for higher complication rate(P<0.05),and a lower value oftestosterone at later times after surgery was a better predictor of complications. CONCLUSION:Patients with low testosterone level were prone to higher postoperative complications,which was evident in both sexes.However,further studies are necessary to support this result.Birendra Kumar Sah 2009World Journal of Gastroenterology2009,15,44:1
