Comparison of Patient Survival after Resection for Pulmonary Carcinoid Tumors Compared to Other Neuroendocrine Tumors: A United States Population Study  [PDF]
Jay M. Bhatt, J. Nilas Young, David T. Cooke
Open Journal of Thoracic Surgery (OJTS) , 2012, DOI: 10.4236/ojts.2012.24020
Abstract: Background: We hypothesized: 1) resected pulmonary typical carcinoid (TC) will show a favorable clinical pattern compared to other bronchopulmonary neuroendocrine tumors (BPNETs); and 2) Atypical carcinoid (AC) and large-cell neuroendocrine carcinoma (LCNEC) patients will have similar outcomes. Methods: The Surveillance Epidemiology and End Result database was queried to compare demographics and tumor specific variables in patients undergoing resection for TC, AC, LCNEC and small cell lung cancer (SCLC) from 2001 to 2006. Results: Similar to LCNEC, AC patients had greater incidence of histologic positive lymph nodes compared to TC (P < 0.001). Survival analysis showed a mean survival of 40.0 ± 1.9 months for SCLC, 46.2 ± 2.2 months for LCNEC, 58.3 ± 2.3 months for AC, and 70.2 ± 0.2 months for TC tumors. TC patients demonstrated favorable survival, and SCLC patients poorer survival, compared to AC and LNEC patients (P < 0.01). Conclusion: AC tumors are a BPNET histology that exhibits clinical behavior distinct from TC. AC tumors should be staged, and treated with stage appropriate therapeutic strategies similar to other non-small cell lung cancers.
Symmetry of forward and reverse path populations
Divesh Bhatt,Daniel M. Zuckerman
Physics , 2010,
Abstract: In this note, we address formally the issue of symmetry for probabilities of different dynamical pathways in the forward and reverse directions of a conformational transition. Our discussion is based on a decomposition of equilibrium into opposing steady states, and makes clear the conditions necessary for symmetry to apply. From a practical point of view, we also discuss when approximate symmetry is to be expected.
Heterogeneous path ensembles for conformational transitions in semi-atomistic models of adenylate kinase
Divesh Bhatt,Daniel M. Zuckerman
Physics , 2009,
Abstract: We performed "weighted ensemble" path-sampling simulations of adenylate kinase, using several semi-atomistic protein models. Our study investigated both the biophysics of conformational transitions as well as the possibility of increasing model accuracy without sacrificing good sampling. Biophysically, the path ensembles show significant heterogeneity and the explicit possibility of two principle pathways in the Open-Closed transition. We recently showed, under certain conditions, a "symmetry of hetereogeneity" is expected between the forward and the reverse transitions: the fraction of transitions taking a specific pathway/channel will be the same in both the directions. Our path ensembles are analyzed in the light of the symmetry relation and its conditions. In the realm of modeling, we employed an all-atom backbone with various levels of residue interactions. Because reasonable path sampling required only a few weeks of single-processor computing time with these models, the addition of further chemical detail should be feasible.
Impact Analysis of Knowledge Practice for Food Safety in Urban Area of Varanasi
Shuchi Rai Bhatt,S.M. Bhatt,Anita Singh
Pakistan Journal of Nutrition , 2010,
Abstract: The present study was planned with main objective of identifying buying practices of homemakers and their awareness in food practices in Varanasi (urban area). For this objective, questionnaire was prepared and distributed among selected people depends on their age group, sex and educational background. Statistical test were carried out on the basis of frequency of male and female respondents obtained in total respondents (n = 300). Chi square test were carried out and the calculated value were compared with value of t test (0.05) and on this basis, conclusion were drawn. Correlation between different variables was determined for their impact. Study revealed that educated people of both sexes follow slightly good buying practices while homemakers are not following food practices and also they differ significantly in following the practices in term of use of quality water which affects the family health. Study also revealed that age and awareness are not interlinked while education is interlinked with good practices.
Impact of Media and Education on Food Practices in Urban Area of Varanasi
Bhatt Shuchi R, Bhatt Sheeendra M, Singh Anita
National Journal of Community Medicine , 2012,
Abstract: Background: Currently food malpractices are increasing in various metro cities of India and all the measures taken by agencies are failed to detect rapidly and many times it becomes late when the adulteration is detected. Worst scenario is the adulteration of some branded items of the children’s and in the women’s use such as milk cheese, ghee and oils. Therefore, Study for food practices and safety measures was done in selected area of Varanasi which was also validated by the wetlab methods. Methods: For this objective, questionnaire was prepared and distributed among selected people depending on their age group, sex and educational background. Statistical test were carried out on the basis of frequency of male and female respondents obtained in total respondents (n = 300). Chi square test were done and the calculated value were compared with value of t test (0.05) and on this basis, conclusion were drawn. Results: Result shows that regardless of the age income and religion, all of the groups are well aware the food adulteration and educated people are less prone to the effect. In terms of adulteration any how all the stores contains adulterated food however branded items contains less %age of adulteration than local item. This may be caused due to inactive agencies or longer process of legal system Conclusions: Study show that there is lag in following the food practices by all the ages in spite of having good media awareness program and knowledge of food practices.

Ramesh Prasad Bhatt, Sarala Bhatt
American Journal of Plant Sciences (AJPS) , 2016, DOI: 10.4236/ajps.2016.71004
Abstract: Forest and vegetation of particular ecosystem is generally influenced by external factors especially from development activities. Nepal has been endowed with an immense variety of forest resources with its unique biodiversity. The current study is conducted in the temperate forest of central Nepal to compare the state of vegetation recorded during 1995 with the present condition. To identify floristic composition, species distribution and diversity, same location and same size of quadrates were selected in natural forest and planted or regenerated area as in previous study. Measurement and analytical tools for forest and vegetation reveled a total of 19 species and 341 individuals in 0.14 ha regenerated area and 18 species, 17 genera and 260 individuals in 0.16 ha, natural forest areas. However, in 1995, total 31 individuals of 20 woody species, 18 genera and 15 families were recorded within the sampling plots of 0.16 ha of natural forest. Moreover, Alnus nepalensis is found dominating regenerated area and Caryopteris odorata in natural forests whereas in 1995, Litsea chartacea and Maesa chisia were recorded dominant. The Shannon’s diversity H’ = 2.908, E = 0.970 and Var H’ = -0.00 and Simpsons D = 0.027 recorded in 1995 is found to be with higher values when compared with the analysis of present study. Furthermore, in comparison to 1995 study, this study showed lower basal area and timber volume with declining species diversity. Although, the natural forest is found with higher species composition compared to rehabilitated forest, species of herbs and shrubs were found extensively growing.

Advances in Bioscience and Biotechnology (ABB) , 2014, DOI: 10.4236/abb.2014.53030
Abstract:

Aim: Whole genome sequencing and functional annotation of Bacillus nealsonii strain AAU1, an amylolytic anaerobic spore forming isolate from ruminal contents of buffalo. Methods and Results: Morphologically, the strain was observed as slender Grampositive rods, occurring in pairs. Optimal growth was observed at 40°C (range: 30°C to 45°C) and pH 6.5 (range: 5.5 to 7.5) when cultivated in Hungate’s medium supplemented with starch. The microorganism showed extracellular constitutive amylolytic activity, proving to be capable of utilizing glucose, maltose, mannose, trehalose, dextrin and starch under anaerobic conditions. Sequence analysis revealed a GC content of 35.1 mol%. Comparison of housekeeping gene sequences for RNA polymerase subunit B (rpoB) and gyrase A (gyrA) identified sequence similarity within the Bacillus genus, confirmed by 16S rRNA gene sequence similarity which identified Bacillus nealsonii DSM 15077 as the closest publically available relative. Chemotaxonomic analysis provided conflicting results with straight-chain saturated C16: 0/C16:0 aldehyde, C16:0 DMA, C14:0 and monounsaturated 16:1w7c and 16:1w9c the major fatty acids in contrast to those reported for

World Journal of Nuclear Science and Technology (WJNST) , 2017, DOI: 10.4236/wjnst.2017.74024
Abstract: This paper presents a study on the process engineering aspects of relevance to the industrial implementation of ThO2 and (Th, U)O2 mixed oxide (MOX) pellet type fuel manufacturing. The paper in particular focuses on the recycling of thoria based fuel production scrap which is an economically important component in the fuel manufacturing process. The thoria based fuels are envisaged for Advanced Heavy Water Reactor (AHWR) and other reactors important to the Indian Nuclear Power Programme. A process was developed for recycling the chemically clean, off-specification and defective sintered ThO2 and (Th, U)O2 MOX nuclear fuel pellets. ThO2 doesn’t undergo oxidation or reduction and thus, more traditional methods of recycling are impractical. The integrated process was developed by combining three basic approaches of recycling namely mechanical micronisation, air oxidation (for MOX) and microwave dissolution-denitration. A thorough investigation of the influence of several variables as heating method, UO2 content, fluoride and polyvinyl alcohol (PVA) addition during microwave dissolution-denitration was recorded on the product characteristics. The suitability evaluation of the recycled powder for re-fabrication of the fuel was carried out by analyzing the particle size, BET specific surface area, phase using XRD, bulk density and impurities. The physical and chemical properties of recycled powder obtained from the sintered (Th1-y, Uy)O2 (y; 0 - 30 wt%) pellets advocate 100% utilisation for fuel re-fabrication. Recycled ThO2 by integrated process showed distinctly high sinterability compared to standard powder evaluated in terms of surface area and particle size.
Destructive Strength Properties of Recycled Coarse Aggregate
Chetna M Vyas,,Darshana R Bhatt
International Journal of Innovative Technology and Exploring Engineering , 2013,
Abstract: Due to a critical shortage of natural aggregate, the availability of demolished concrete for use as recycled coarse aggregate (RCA) is increasing. Use of waste concrete as RCA conserves natural aggregate, reduces the impact on landfills, save energy and can provide cost benefit. Recycled aggregates are the materials for the future. The application of recycled aggregate has been started in many Asian & Western countries for construction projects. Research Paper reports the basic strength properties of recycled coarse aggregate. It also compares these properties with natural aggregates. Basic changes in all aggregate properties were determined. Basic concrete properties like compressive strength, pull out strength are explained here for different combinations of recycled coarse aggregate with natural aggregate. The compressive strength, pull out strength is used to determine the maximum resistance of a concrete to axial loading of the concrete specimens that having different percentage of recycled coarse aggregate replacement. The testing is just carried out after 28 days of casting. The resting specimen was 100mm diameter and 200 mm height for M25 grade concrete. There were total of six batches of concrete mixes, consists of every 20% increment of recycled aggregate replacement from 0% to 100%.
