Background & objectives: There is poor knowledge and behaviors regarding chronic diseases related nutritional and lifestyle factors among women in low income countries. To evaluate efficacy of a multilevel population-based intervention in improving knowledge and practices for related factors we performed a study in India. Methods: Population based study among women 35-70 years was performed in four urban and five rural locations. Stratified sampling was performed and we enrolled 4624 (rural 2616, urban 2008) of eligible 8000 women (58%). Demographic details, medical history, diet, physical activity and anthropometry were recorded and blood hemoglobin, glucose and total cholesterol determined. Knowledge and behaviors regarding diet in chronic diseases were inquired in a randomly selected 100 women at each site (n = 900). A systematic multilevel population based intervention (using posters, handouts, street plays, public lectures, group lectures and focused group discussions) was administered over 6 months at each site. The questionnaire was re-administered at the end in random 100 women (n = 900) and differences determined. Descriptive statistics are reported. Comparison of parameters before and after intervention was assessed using Mann Whitney test. Results: Prevalence (%) of chronic disease related lifestyles and risk factors in rural/urban women, respectively, was illiteracy in 63.6/29.4, smoking/tobacco use 39.3/18.9, high fat intake 93.6/93.4, high salt intake 18.2/12.6, low physical activity 59.5/70.2, overweight/obesity 22.5/45.6, truncal obesity 13.0/44.3, hypertension 31.6/48.2, hypercholesterolemia 13.5/27.7, and diabetes in 4.3/15.1 percent. Composite chronic diseases knowledge at baseline vs after intervention increased significantly in overall (32.0 vs 62.0), rural (29.0 vs 63.5) and urban (39.5 vs 60.5) groups (p < 0.001). Significant increase in knowledge regarding diet in hypertension, diabetes, heart disease and anemia as well as importance of dietary proteins, fats, fibres and fruits was observed (p < 0.001). There was insignificant change in most of the practices regarding intake of low fat, high protein, high fibre diet except sieving the flour which declined significantly (80.1 vs 53.6, p < 0.001). Conclusions: A short-term multilevel population-wide intervention among women in rural and urban locations in India increased chronic disease knowledge but failed to influence practices. © 2012, Cardiological Society of India.

Palaeoclimate estimates derived from plant-based proxies are potentially subject to uncertainties arising from taphonomic filtering. In any given fossil assemblage it is possible to identify the kinds of likely taphonomic influences, but virtually impossible to quantify the uncertainties they introduce because filtering removes information. Because that information is missing it cannot be measured. An alternative approach is to measure the maximum uncertainty possible due to specific information loss within recognised analytical protocols. In respect of the multivariate foliar physiognomic technique known as CLAMP (Climate Leaf Analysis Multivariate Program) we have attempted to do this by experimentally degrading both the character state scores and the number and composition of taxa as subsets of the full range of character states and taxonomic diversity in the source vegetation.In this study a stand of protected vegetation on Green Island (23° 08' 58' N, 88° 26' 59.19' E) within the Ganges Delta was sampled following standard CLAMP protocols. The island is subject to annual flooding during the monsoon season and is typical of the kinds of naturally disturbed vegetation likely to be represented in ancient delta floodplain assemblages. A total of 56 woody dicot taxa were scored in the living vegetation. From this 'complete' sample leaf character states for lobing, margin, size, apex, base, length-to-width ratio and shape were removed in turn from all 56 taxa to give 7 analyses simulating worst case taphonomic loss of physiognomic data. Ten subsets of 20 randomly selected taxa were also analysed to simulate taphonomic diversity loss of almost two thirds of the potentially available taxa in the source vegetation. In all cases the completeness statistic remained above the CLAMP recommended minimum of 0.66. The results show that in all cases the uncertainties arising from taphonomic processes, either through taphonomic diversity or character state filtering, were not significantly different from the statistical CLAMP uncertainties associated with the most commonly used calibration dataset (Physg3brc), and gave similar climatic estimates as the source vegetation in its entirety. This suggests that stratigraphically well constrained museum collections lacking detailed sedimentary or taphonomic context can still be used with confidence for CLAMP analyses. Leaf margin analysis displayed a greater sensitivity to diversity loss. The Green Island estimates suggested a cooler, moister climate than that indicated by the observed regional climate as derived from a 0.5 × 0.5° gridded data set used in climate modelling evaluation. The likely cause for this disparity is the prevalence of a sub-canopy microclimate signal developed by the vegetation itself, and this is strongly dependant on the temperature and humidity characteristics of the regional climate as well as the proximity to water bodies. Within the sample size limitations of this study this disparity is larger than that introduced by taphonomic processes, but potentially can be corrected for. © 2011 Elsevier B.V.

We have designed a dodecamer d-AGATCTAGATCT (RY12) with alternate oligopurines and oligopyrimidines tracts and its homologous 28 bp hairpin oligomer (RY28) that forms a triple helix only in the presence of a pentapeptide REWER. An intermolecular triplex is formed by the single strand invasion of the RY28 duplex by RY12 in the presence of REWER. 5′- oligopurine end of RY12 binds to oligopurine sequence of RY28 in a parallel orientation and its oligopyrimidine stretch then changes strand and adopts an antiparallel orientation with the other strand of the duplex. Evidence for the formation of the triplex come from our studies of the UV melting curves, UV mixing curves, gel retardation assay, and chemical sequencing of 1:1 mixture of dodecamer and hairpin oligonucleotides in the presence and absence of the peptide REWER. RY12 exists as a duplex that melts at 35°C. The hairpin (RY28) melts at 68°C. 1:1 mixture of RY12 and RY28 in the absence of REWER gives a biphasic transition curve with thermodynamic properties corresponding to those of the melting of the duplex of RY12 and the hairpin RY28. However, the melting curve of this mixture is triphasic in the presence of the REWER; the thermodynamic parameters associated with the first phase (melting of the duplex of RY12), second phase (melting of the triplex) and the third phase (melting of the hairpin) show dependence on the molar ratio of peptide to oligonucleotides. Under appropriate conditions, gel retardation assay showed a shifted band that corresponds to a possible triplex. Chemical sequencing of KMnO4 and DEPC treated mixture of RY12, RY28 and REWER revealed the footprint of triplex. © 2013 Das et al.

Rapid increase in human population, industrialization, automobiles and GDP drives world energy requirements and in particular fossil fuels with the enhanced site of is likely to deplete limited natural resources over short period of time whereas sustained development needs demandancy energy cannot be compromised. So search for alternative fuel is only the way to overcome this problem of upcoming energy crisis. In this aspect biofuel is a sustainable option. Production of biofuels from various biomasses becomes a very interesting field of research. Biomasses used for biodiesel production include algae, animal fats, vegetable oils like soyabean, rapeseed, jatropha, mahua, mustard, flax, sunflower, palm, hemp, field pennycress, Pongamia pinnata etc. Presently, the population explosion needing huge food demands, agricultural land cannot be used for biofuel production. To mitigate the problem using algae for biodiesel production could play an important role. Certain species of algae contains oil at a very significant level and also are fast growing. This algal oil could be processed into biodiesel easily. Provided certain conditions are maintained during the process. Biodiesel production from algae involves identification of proper algal species, cultivation of algae by maintaining certain parameters (like temperature, pH, nutrients, and aeration), harvesting, oil extraction, and process standardization. Biodiesel production from algae is in an initial stage which needs attentions of researchers for further explorations.

The present study investigated externalizing and internalizing behaviours in Greek (n = 599), Russian (n = 596), Indian (n = 571), and Chinese (n = 376) 7- to-12-year-old children. The Fairy Tale Test was used to measure impulsive and motivated aggression, fear of aggression, anxiety, and depression. The results indicated culture-specific patterns of the aforementioned behaviours. Greek children demonstrated the highest levels of impulsive and motivated aggression, while Russian children had the highest fear of aggression. Chinese children appeared to be most anxious among other cultural groups. Both Russian and Indian children were more depressed than their Greek and Chinese counterparts. Gender and age difference were obtained only for impulsive aggression. Regardless of culture, boys scored higher compared to girls; and 7- to 8-year-old children demonstrated higher level of impulsive aggression than older children. The obtained results are interpreted in light of contextual differences in child socialization in four cultures; suggestions for school psychology practices are offered. © The Author(s) 2011.

The antiapoptotic Bcl-2 protein is overexpressed in a variety of cancers, particularly leukemias. In some cell types this is the result of enhanced stability of bcl-2 mRNA, which is controlled by elements in its 3′-untranslated region. Nucleolin is one of the proteins that binds to bcl-2 mRNA, thereby increasing its half-life. Here, we examined the site on the bcl-2 3′-untranslated region that is bound by nucleolin as well as the protein binding domains important for bcl-2 mRNA recognition. RNase footprinting and RNA fragment binding assays demonstrated that nucleolin binds to a 40-nucleotide region at the 5′ end of the 136-nucleotide bcl-2 AU-rich element (AREbcl-2). The first two RNA binding domains of nucleolin were sufficient for high affinity binding to AREbcl-2. In RNA decay assays, AREbcl-2 transcripts were protected from exosomal decay by the addition of nucleolin. AUF1 has been shown to recruit the exosome to mRNAs. When MV-4-11 cell extracts were immunodepleted of AUF1, the rate of decay of AREbcl-2 transcripts was reduced, indicating that nucleolin and AUF1 have opposing roles in bcl-2 mRNA turnover. When the function of nucleolin in MV-4-11 cells was impaired by treatment with the nucleolin-targeting aptamer AS1411, association of AUF1 with bcl-2 mRNA was increased. This suggests that the degradation of bcl-2 mRNA induced by AS1411 results from both interference with nucleolin protection of bcl-2 mRNA and recruitment of the exosome by AUF1. Based on our findings, we propose a model that illustrates the opposing roles of nucleolin and AUF1 in regulating bcl-2 mRNA stability. © 2010 by The American Society for Biochemistry and Molecular Biology, Inc.

InterCeram: International Ceramic Review | Year: 2013
The Bokaro Steel Plant of the Bokaro Steel Authority of India Ltd. (BSL-SAIL) is India's largest flat steel producer. It has five 2000-2500 m 3 capacity (useful volume) blast furnaces for production of hot metal. These furnaces are currently producing 11,550 mt of processed metal on a daily basis. The five furnaces are operated at a top pressure of 1.0-1.65 kg/cm2, with average productivity of 1.55 mt/m3/day of hot metal at a temperature of 1480-1510°C. In the Bokaro Steel Plant, each blast furnace (BF) has twin cast houses offset from each other by 180°. To increase the productivity of the BFs, there is continual demand for ever higher throughput of hot metal tonnage from the cast house through the main trough, metal runners and other parts of the plant, and a desire to move to hotter metal temperatures. The throughput and operational life of BF troughs and runners depends on the characteristics of their refractory components, lining design, installation, and maintenance and operating regimes. The paper describes the details of refractory-related operating parameters, product (Al 2O3-SiC-C) characteristics, trough/ runner material reactions in contact with iron, slag and air/slag interfaces, installation techniques, and causes of lining wear and other critical issues. New generation Al2O3-SiC-C low moisture castables with varied SiC content were also created and tested for strength and slag resistance.
