Background: The prevalence of child obesity is increasing rapidly worldwide. In developing countries such as India, especially in urban populations, childhood obesity is emerging as a major health problem. In view of these contexts, the present study was undertaken to estimate the prevalence of overweight and obesity in an urban population of girl adolescent students attending the English Medium School in Kolkata, India. Methods: A total of 571 girl students, aged 12-18 years, were evaluated. Cole et al. (2000) recommended cut-off points were utilized to assess overweight and obesity. Results: the overall prevalence rates of overweight and obesity were 28.5% and 4.2% respectively. The rate of overweight was the highest when compared with that of different parts of India, including Kolkata, and also when compared to rates from the USA and Great Britain. Conclusions: In the context of the present study, it can be presumed that, the higher prevalence of overweight in these school children may be due to their eating habits, as well as to their lack of awareness on proper eating habits. In addition, low involvement in physical activities may also have influenced the rate of overweight and obesity. Thus, it can be concluded that the study definitely highlighted the existence of an obesity threat, which is likely to persist among Bengalee school children of wealthier families.

The manuscript studies autocorrelation and cross correlation of SENSEX fluctuations and Forex Exchange Rate in respect to Indian scenario. Multifractal detrended fluctuation analysis (MFDFA) and multifractal detrended cross correlation analysis (MFDXA) were employed to study the correlation between the two series. It was observed that the two series are strongly cross correlated. The change of degree of cross correlation with time was studied and the results are interpreted qualitatively. © 2016 Elsevier B.V.

In this paper multifractal analysis of fluctuation pattern of pions emitted in 32S-AgBr and 16O-AgBr interactions at 200 GeV and 60 GeV, respectively, is performed in the framework of multifractal detrended fluctuation analysis (MFDFA). The pseudorapidity and azimuthal distributions exhibit multifractal scaling properties at both energies. The variation of multifractal width with energy is also studied. The study reveals a dependence of multifractal width on energy in pseudorapidity space while no such dependence is observed in azimuthal space. © World Scientific Publishing Company.

2,2′-Bipyridine (bpy), 1,10-phenanthronline (phen) and p-nitro-o-aminophenol (NO2LH2) oxidovanadium complexes of the types [(LONO 2-)(VO)(bpy)] (1), [(LONO 2-)(VO)(phen)] (2) and [(LONO 2-)(VO)(NO2LISQ ·-)][NHEt3] (3- NHEt3 +; NO2LISQ ·- = p-nitro-o-iminobenzosemiquinonate radical) were isolated with (E)-2-(3-hydroxy-3-phenyltriaz-1-en-1-yl)benzoic acid (LONOH2) as a coligand. The single-crystal X-ray bond parameters and electron paramagnetic resonance (EPR) spectra authenticated that 1 and 2 are the oxidovanadium(IV) complexes of bpy and phen, whereas 3- is the NO2LISQ ·- complex of oxidovanadium(IV) and undergoes reversible one-electron oxidation and reduction at lower potentials. Density functional theory (DFT) calculations established that the closed-shell-singlet (CSS) solution of 3- is unstable owing to open-shell-singlet (OSS) perturbation. The CSS → OSS charge-transfer transition that appears at λ = 632 nm is absent for 1 and 2. Complex 3 is a hybrid of the [(LONO 2-)(VO2+)(NO2LIQ)] (NO2LIQ = p-nitro-o-iminobenzoquinone) and [(LONO 2-)(VO3+)(NO2LISQ ·-)] states, whereas 32- is an oxidovanadium(IV) complex of the type [(LONO 2-)(VO2+)(NO2LAP 2-)]2- (NO2LAP 2- = p-nitro-o-amidophenolato). © 2016 WILEY-VCH Verlag GmbH & Co.

In this paper, a variant of windowed Huffman coding with limited distinct symbols is proposed. Symbols most recently processed are stored in a window where the number of distinct symbols cannot exceed a specified threshold. But, if the number of distinct symbols exceeds a specified threshold, least recently used symbol is removed from the window instead of oldest symbol of the window. Then, another variant of the method is proposed where instead of single window two windows are used. The most recently processed symbols are kept in a small primary window buffer. A comparatively large secondary window buffer is used to store more past processed symbols. The first proposed technique significantly improves the compression rates of most of the file type. The compression rates of the second proposed technique are not so poor than its counter parts. © Springer International Publishing Switzerland 2015.

Purpose: Developing countries like India, accounts for about 40 percent of undernourished children in the World and it is largely due to the result of dietary inadequacy in relation to their needs. The purpose of this paper was to evaluate the changes in the nutritional status of the children, from their preschool days to the present primary school days.Design/methodology/approach: The present investigation was conducted at 20 Integrated Child Development Service (ICDS) centers (Center-A) and 15 primary schools (Center-B) in Bali Gram Panchayat, Arambag, Hooghly District of West Bengal, India, at an interval of three to four years. A total of 1,012 children (boys=498; girls=514) aged two to six years old enrolled in these ICDS centers and a total of 603 children (boys=300, girls=303), aged five to ten years were studied from the 15 primary schools who were the beneficiaries of ICDS centers. Underweight (weight-for-age Z-score (WAZ)) and wasting (weight-for height Z-score (WHZ)) were used to assess the nutritional status. Findings: The nutritional situation (both in case of underweight and wasting) was better in Center B as compared with Center A. In general, the nutritional condition of boys was better than girls. Center had a very significant effect on both WAZ as well as WHZ, irrespective of age and sex. Sex has a significant impact only on WAZ. Interestingly, there was no significant sex-center interaction for both WAZ as well as WHZ. The children of the area were getting Mid Day Meal supplied through the school authorities which was comparatively better than the ICDS centers' food supplementation. Better monitoring of nutritional supplementation at primary schools may be an important factor. Practical implications: In ICDS centers, only the Anganwari worker is responsible in running and implementing the programs offered by the Government. However, at primary schools, the active involvement of all the teachers to run the program may have effectively led to have better results. Furthermore, the Government's focus should not be only on the increase the area covered by the ICDS program, but focus should be to increase the quality of food supplied, proper monitoring of the implementation and increase the allocation of funds. Appropriate measures may be taken by the authorities regarding this. Originality/value: The results of the study will help in policy making in reducing the prevalence of undernutrition. © Emerald Group Publishing Limited.

Visceral leishmaniasis (VL) caused by the parasite Leishmania donovani is a potentially fatal disease. Available limited drugs are toxic, require prolonged treatment duration, and are costly. A low-cost parenteral formulation of paromomycin sulfate (PM) has recently been approved for the treatment of VL. Monotherapy with PM runs the risk of development of resistance. Hence, efforts are needed to develop a combination therapy of PM with other drugs to shorten the duration of treatment and prolong the effective life of the drug. PM was formulated with leishmanicidal stearylamine (SA)-bearing phosphatidylcholine (PC) liposomes for low-dose therapy. In vitro and in vivo antileishmanial effects of the combination drug were determined. The immunomodulatory role of PC-SA - PM was determined using enzyme-linked immunosorbent assay (ELISA) and flow cytometry. Excluding the spleen, for which the therapeutic effect was additive, a remarkable synergistic activity toward cure and prophylaxis with a single-shot low-dose treatment with PC-SA-associated PM was achieved with BALB/c mice. PC-SA - PM showed an immunomodulatory effect on CD4 + and CD8 + T cells for gamma interferon (IFN-γ) production and downregulated disease-associated interleukin-10 (IL-10) and transforming growth factor β (TGF-β) to almost negligible levels. Such combination chemotherapy may provide a promising alternative for the cure of leishmaniasis, with a plausible conversion of the host immune response from a disease-promoting pattern to a Th1-biased response indicative of long-term resistance.

Background: Visceral leishmaniasis (VL), a potentially fatal disease, is most prevalent in the Indian subcontinent, East Africa and South America. Since the conventional antileishmanial drugs have many limitations we evaluated a new ergosterol rich liposomal amphotericin B formulation, KALSOME™10 for its leishmanicidal efficacy, tolerability and immunomodulatory activity. Methods: Normal healthy mice were treated with 3.5 mg/kg single and 7.5 mg/kg single and double doses of KALSOME™10. Liver and kidney function tests were performed fourteen days after treatment. Next, normal mice were infected with Leishmania donovani amastigotes. Two months post infection they were treated with the above mentioned doses of KALSOME™10 and sacrificed one month after treatment for estimation of parasite burden in the liver and spleen by Limiting Dilution Assay. Leishmanial antigen stimulated splenocyte culture supernatants were collected for cytokine detection through ELISA. Flow cytometric studies were performed on normal animals treated with KALSOME™10, Amphotericin B (AmB) and AmBiosome to compare their immunomodulatory activities. Results: The drug was found to induce no hepato- or nephrotoxicities at the studied doses. Moreover, at all doses, it led to significant reduction in parasite burden in two month infected BALB/c mice, with 7.5 mg/kg double dose resulting in almost complete clearance of parasites from both liver and spleen. Interestingly, the drug at 7.5 mg/kg double dose could almost completely inhibit the secretion of disease promoting cytokines, IL-10 and TGFβ, and significantly elevate the levels of IFNγ and IL-12, cytokines required for control of the disease. Mice treated with KALSOME™10 showed elevated levels of IFNγ and suppressed IL-10 secretion from both CD4+ and CD8+ subsets of T cells, as well as from culture supernatants of splenocytes, compared to that of normal, AmB and AmBisome treated animals. Conclusions: Treatment of infected mice with 7.5 mg/kg double dose of KALSOME™10 was safe and effective in clearing the parasites from the sites of infection. The drug maintains the inherent immunomodulatory activities of AmB by effectively suppressing disease promoting cytokines IL-10 and TGFβ, thereby boosting IL-12 and IFNγ levels. This emphasizes KALSOME™10 as a promising drug alternative for lifelong protection from VL. © Asad et al.

The three conventional anthropometric indicators of childhood undernutrition are stunting (low height-for-age), underweight (low weight-for-age) and wasting (low weight-for-height). Recently a new composite index, namely the Composite Index of Anthropometric Failure (CIAF) has been proposed and utilised to study childhood undernutrition. In this paper, we have attempted to construct three new indices of undernutrition, relative to the CIAF. These three indices are: Stunting Index (SI) = Stunting/CIAF, Underweight Index (UI) = Underweight/CIAF and Wasting Index (WI) = Wasting/CIAF. Furthermore, we have calculated and compared these indices using our dataset as well as other existing datasets. Using our dataset, the sex-combined values of SI, UI and WI were 0.364, 0.866 and 0.684, respectively. The corresponding values among boys were 0.364, 0.866 and 0.729. Among girls, they were 0.380, 0.866 and 0.641, respectively. When applied to the all India dataset, the values of SI, UI and WI were 0.756, 0.788 and 0.266, respectively. Similar values (SI = 0.723, UI = 0.681, WI = 0.294) were observed when they were computed on data available from Coimbatore, South India. In conclusion, we suggest that these three new indices provide additional information on the prevalence of different forms of undernutrition relative to the total level of undernutrition in a particular population.
