EFFECT OF PIGEON ORIGIN NEWCASTLE DISEASE VIRUS ON VARIOUS LIVER ENZYMES AND ASSOCIATED PATHOLOGICAL CHANGES IN EXPERIMENTALLY INFECTED PIGEONS

Newcastle disease virus (NDV) was isolated from a field outbreak in pigeons. The virus was characterized by haemagglutination test (HA) and confirmed by haemagglutination inhibition test (HAI). The pathotyping was done by mean death time (MDT), intracerebral pathogenicity index (ICPI) and intravenous pathogenicity index (IVPI). The ELD50 of the velogenic strain was 10-4.66/0.1 ml. Thirty-nine pigeons were randomly divided into three equal groups. Pigeons of one group were vaccinated with ND vaccine (LaSota strain) intraocularly after 14 days of procurement, while the other two groups served as vaccinated and non-vaccinated controls. Birds of these two groups were challenged with velogenic strain of field isolate of NDV 7 days post-vaccination. Birds were kept under observation for 15 days post-challenge. Haemorrhages and congestion were observed in trachea, lungs, liver, proventriculus and intestine of pigeons infected with NDV. Concentrations of AST, ALT and ALP did not differ among pigeons of the three groups

Maternal risk factors associated with low birth weight in Karachi: A case-control study

To evaluate maternal risk factors associated with low birth weight (LBW) among women aged 15-35 years, we carried out a hospital-based, case-control study on 262 cases (mothers of neonates weighing \u3c or = 2.5 kg) and 262 controls (mothers of neonates weighing \u3e 2.5 kg). Odds of delivering a low-birth-weight baby decreased with increase in maternal haemoglobin [odds ratio (OR): 0.701; 95% confidence interval (CI): 0.62-0.79]. Odds were greater among mothers not using iron supplements during pregnancy (OR: 2.88; 95% CI: 1.83-4.54). Mothers of LBW babies had lower haemoglobin levels before delivery

Clinical features and management of malignant ascites

Retrospective analysis of 45 patients (33 females, 12 males) with cytologically-proven malignant ascites is presented. Abdominal pain was the most frequent symptom (69%). Fiftythree percent cases had low serum albumin. Ascitic fluid was haemorrhagic or serosanguinous in 48% cases, in the rest it was clear or straw-coloured. Peritoneal effusion was exudative in 84% cases. Mean glucose content of ascitic fluid was 95 mg/dl and the mean white cell count of 919 cells/cmm. Vast majority (82%) of the cases had metastatic adenocarcinomas. Primary malignancy was mostly ovarian (47%) followed by non-Hodgkin\u27s lymphoma (11%) and gall bladder carcinoma (9%). Primary site could not be identified in 13% cases. Sixty-two percent patients received systemic chemotherapy for the underlying malignancy, of these 43% had complete or partial resolution of the ascites. Of the patients whose long-term follow-up is available, 54% were alive with a median follow-up of 9 months

Large-scale shell-model calculations near mass region 100-130

308-313In this work, we have presented a microscopic shell-model description of the structure and collective behavior of intermediate-mass nuclei around doubly magic 100Sn and 132Sn nuclei. The Sn-isotopes lie between the two doubly magic nuclei and cover a range from exotic proton-rich N=Z nuclei to exotic neutron-rich nuclei with N/Z > 1.6. The results obtained using BIGSTICK code for the low-level excitation states and transition probabilities for the studied Sn and Ba isotopic chains have been discussed in the radiance of available experimental data. We have used 100Sn as a core for all the studied isotopes with the same valence space (i.e. 1d5/2, 2s1/2, 1d3/2, 0g7/2, 0h11/2 or ‘sdgh’) for both protons (Z) and neutrons (N) between 50 and 82. These calculations are performed by means of globally optimized monopole effective interaction for the sdgh-shell

The family planning know-do gap among married women of reproductive age in urban Pakistan

Objective: To examine the prevalence and predictors of family planning (FP) know-do gaps among married women of reproductive age (MWRA) in low socio-economic urban areas of Karachi, Pakistan.Design: This was a cross-sectional survey of randomly selected 7288 MWRA (16-49 years) to identify predictors of the know-do gap in FP using a logistic regression model.Results: More than one third (35.5%) of MWRA had FP know-do gap, i.e., despite having a knowledge of contraceptives and desire to limit or delay childbearing, they were not using contraceptives. Women were less likely to use FP if they were getting older (25-35 years: OR 1.45, 95% CI 1.09-1.94; \u3e35 years: OR 3.02, 95% CI 1.90-4.80), from certain ethnicities (Sindhi: OR 1.64, 95% CI 1.11-2.42; Saraiki: OR 1.66, 95% CI 1.01-2.71; other minorities: OR 2.37, 95% CI 1.63-3.44); did not receive FP counselling: OR 1.43, 95% CI 1.13-1.80; and had not made a joint decision on FP: OR 1.44, 95% CI 1.06-1.98). Conversely, women were more likely to use contraceptives if they had \u3e10 years of schooling (OR 0.66, 95% CI 0.46-0.94), with each increasing number of a living child (OR 0.68, 95% CI 0.62-0.75) and each increasing number of contraceptive method known (OR 0.93, 95% CI 0.88-0.98).Conclusion: The predictors associated with the FP know-do gap among MWRA should be considered when planning future strategies to improve the contraceptive prevalence rate in Pakistan

Globalising assessment: an ethnography of literacy assessment, camels and fast food in the Mongolian Gobi

What happens when standardised literacy assessments travel globally? The paper presents an ethnographic account of adult literacy assessment events in rural Mongolia. It examines the dynamics of literacy assessment in terms of the movement and re-contextualisation of test items as they travel globally and are received locally by Mongolian respondents. The analysis of literacy assessment events is informed by Goodwin’s ‘participation framework’ on language as embodied and situated interactive phenomena and by Actor Network Theory. Actor Network Theory (ANT) is applied to examine literacy assessment events as processes of translation shaped by an ‘assemblage’ of human and non-human actors (including the assessment texts)
