Abstract
The nodular tapeworm, Raillietina echinobothrida is a well studied avian gastrointestinal parasite of family Davaineidae (Cestoda: Cyclophyllidea). It is reported to be the largest in size and second most prevalent species infecting chicken in north-east India. In the present study, morphometrical methods coupled with the molecular analysis of the second internal transcribed spacer (ITS2) region of ribosomal DNA were employed for precise identification of the parasite. The annotated ITS2 region was found to be 446 bp long and further utilized to elucidate the phylogenetic relationships and its species-interrelationships at the molecular level. In phylogenetic analysis similar topology was observed among the trees obtained by distance-based neighbor-joining as well as character-based maximum parsimony tree building methods. The query sequence R. echinobothrida is well aligned and placed within the Davaineidae group, with all Raillietina species well separated from the other cyclophyllidean (taeniid and hymenolepid) cestodes, while Diphyllobothrium latum (Pseudophyllidea: Diphyllobothriidae) was rooted as an out-group. Sequence similarities indeed confirmed our hypothesis that Raillietina spp. are neighboring the position with other studied species of order Cyclophyllidea against the out-group order Pseudophyllidea. The present study strengthens the potential of ITS2 as a reliable marker for phylogenetic reconstructions.

Abstract
The present pot culture study was carried out for the potential phytostabilisation of iron ore tailings using lemon grass (Cymbopogon flexuosus) a drought tolerant, perennial, aromatic grass. Experiments have been conducted by varying the composition of garden soil (control) with iron ore tailings. The various parameters, viz. growth of plants, number of tillers, biomass and oil content of lemon grass are evaluated. The studies have indicated that growth parameters of lemon grass in 1:1 composition of garden soil and iron ore tailings are significantly more (-5% increase) compared to plants grown in control soil. However, the oil content of lemon grass in both the cases more or less remained same. The results also infer that at higher proportion of tailings the yield of biomass decreases. The studies indicate that lemongrass with its fibrous root system is proved to be an efficient soil binder by preventing soil erosion.

Abstract
Dolochar, a waste material generated in sponge iron industry, is processed and put to test as an adsorbent for removal of Cd(II) and Cr(VI) ions from aqueous solutions. The dolochar samples were characterised to determine the different phases and their distribution by reflection microscopy. The analysis indicated that the sample consists of metallic iron, fused carbon, and Ca-Mg bearing phases (Ca-Mg-silicate-oxide) along with lots of voids and pores. The fixed carbon (FC) content of the material is 13.8% with a Langmuir surface area of 81.6m(2)/g and micropore area of 34.1m(2)/g. Batch adsorption experiments have been conducted to study the sorption behaviour of Cd(II) and Cr(VI) ions on dolochar as a function of particle size, contact time, adsorbent dosages, pH and temperature. It is observed that higher pH and temperature enhances sorption of Cd(II) ions. In contrast, the adsorption for Cr(VI) is found to be better in acidic pH in comparison to alkaline media. The equilibrium adsorption isotherm data are tested by applying both Langmuir and Freundlich isotherm models. It is observed that Langmuir isotherm model fitted better compared to the Freundlich model indicating monolayer adsorption. The thermodynamic parameters such as ΔG°, ΔH° and ΔS° indicate the effectiveness of dolochar to remove Cd(II) and Cr(VI) ions from aqueous solution. The kinetics of adsorption is found to better fit to pseudo second order reaction.

Abstract
AbstractWe have developed a nanogrowth technology for the fabrication of periodic arrays of semiconductor nanostructures on silicon that is currently being investigated for silicon based x-ray detectors. The semiconductor nanostructures are formed by chemical synthesis in pores of a template created by the anodization of aluminum on a silicon substrate. The use of the silicon substrate allows greater control over the aluminum thin film properties, better in situ monitoring of the pore formation process, and the direct integration of nanostructure arrays with conventional silicon technology.

Abstract
INTRODUCTION The proportion of the elderly population in Nepal, though low, is steadily increasing. Studies on drug utilisation among geriatric patients in Western Nepal, a region with the highest proportion of the elderly in all of Nepal, are lacking. The present study was carried out at the Manipal Teaching Hospital, a 700-bed teaching hospital in Pokhara, Western Nepal. METHODS The study was carried out from June 1, 2005 to May 31, 2006 using case records of discharged patients aged 60 years and older. This was an observational study that utilised a retrospective case notes review methodology. The microorganisms isolated on culture and their antibiotic sensitivity patterns were studied. Drug consumption was measured by the defined daily dose (DDD) per 100 bed-days. The mean cost of the drugs was calculated. The percentage of drugs prescribed by generic name and the percentages of fixed-dose combinations used were noted. The basic demographic information of older inpatients, drug utilisation patterns, drug consumption using DDD, organisms isolated and their antibiotic sensitivity patterns, and the mean cost of the drugs were studied. RESULTS A total of 548 patients were admitted. Hypertension, acute exacerbation of chronic obstructive pulmonary disease and cancer were the most common illnesses among the patients. The mean number of drugs consumed by each patient was 7.73. Escherichia coli and Pseudomonas aeruginosa were the most common microorganisms isolated. Ranitidine, multivitamins, amlodipine, ipratropium and dextrose normal saline were most commonly prescribed. The DDD per 100 bed-days of ranitidine and omeprazole (highest values) was 33.48 and 3.51, respectively. The mean cost of drugs was USD26.6, and antibiotics accounted for around 40 percent of the cost. CONCLUSION The use of a high number of drugs, and of parenteral drugs and intravenous fluids, is a common problem. The prescription of generic drugs is low. Guidelines for the use of drugs in the elderly are required and further studies are needed on this issue.

Abstract
A total of 2169 samples from 21 tribal populations from different regions of India were scanned for the Y-chromosome Alu polymorphism. This study reports, for the first time, high frequencies (8-65%) of Y Alu polymorphic (YAP) insertion in northeast Indian tribes. All seven Jarawa samples from the Andaman and Nicobar islands had the YAP insertion, in conformity with an earlier study of Andaman Islanders. One isolated case with haplotype E* was found in Dungri Bhill, a western Indian population, while YAP insertion in northeast India and Andaman tribes was found in association with haplotype D* (M168, M174). YAP insertion frequencies reported in the mainland Indian populations are negligible, according to previous studies. Genetic drift may be the causative factor for the variable frequency of the YAP insertion in the mainland populations, while the founder effect may have resulted in the highest incidence of haplotype D among the Andaman Islanders. The results of YAP insertion and the evidence of previous mtDNA studies indicate an early out of Africa migration to the Andaman and Nicobar Islands. The findings of YAP insertion in northeast Indian tribes are very significant for understanding the evolutionary history of the region.

Abstract
AIMS To (i) study the serogroup distribution and virulence characteristics of non-sorbitol-fermenting Escherichia coli isolates from foods of animal origin and cattle faeces and (ii) re-examine the true sorbitol and beta-D-glucuronidase (GUD) reactions of sorbitol-negative (Sor(-)) strains from MacConkey sorbitol agar (SMAC) to assess their phenotypic similarity with E. coli O157. METHODS AND RESULTS One hundred and thirty Sor(-)E. coli were isolated from 556 food samples and 177 cattle stool samples using cefixime tellurite-supplemented SMAC (CT-SMAC) and chromogenic HiCrome MS.O157 agar respectively. Based on typing of somatic antigen, the isolates were classified into 38 serogroups. PCR results identified about 40% strains, belonging to O5, O8, O20, O28, O48, O60, O78, O82, O84, O101, O110, O123, O132, O156, O157, O-rough and OUT as Shiga toxigenic. Majority of O5, O84, O101, O105, O123, O157, O-rough and OUT strains were enterohaemolytic. Further, 39.2% and 63.1% of Sor(-) isolates from CT-SMAC fermented sorbitol in phenol red broth and hydrolysed 4-methylumbelliferyl-beta-D-glucuronide (MUG) respectively. Members of serogroups O5, O28, O32, O81, O82, O84, O101, O-rough lacked both the sorbitol fermentation (broth test) and GUD activity and might create confusion in phenotypic identification of E. coli O157. CONCLUSIONS Sor(-)E. coli isolates from raw meat, milk, shrimp and cattle stool belonged to 38 serogroups, with E. coli O157 constituting only 14.6% of the isolates. Many of these nonclinical Sor(-) strains were potentially pathogenic. Nearly 39% of these Sor(-)E. coli from CT-SMAC fermented sorbitol in broth, indicating the need for confirmation of sorbitol reaction in broth. SIGNIFICANCE AND IMPACTS OF THE STUDY Classical sorbitol utilization and GUD tests are not likely definitive tests for E. coli O157. Further improvement of differential media based on these phenotypic properties is necessary for detection of pathogenic serotypes from foods and environmental samples.
