Abstract
The investigation of micro or nano plastics behavior in the environment is essential to minimize the hazards of such pollutants on humans. While the conventional method requires sophisticated procedures and a lot of animal subjects, the nuclear technique confers a sensitive, accurate, and real-time method using radiolabeled micro or nano plastics as a tracer. In this study, polystyrene sulfonate-based microplastic (PSM) was developed with a size of around 3.6 μm, followed by radiolabeling with iodine-131 (131I) or zinc-65 (65Zn) for microplastic radiotracer model. After a stability study in seawater, phosphate buffer saline (PBS), and human serum albumin (HSA) for fifteen days, PSM-131I remained stable (>90 %), except in HSA (50-60 % after day-9), while PSM-65Zn was unstable (<50 %).

Abstract
The microplastics amount in the environment is significantly increasing due to human activity, and the hazards are still being investigated. To evaluate the fate of microplastics in organisms, an accurate, fast, and sensitive method is required. Nuclear technology harnessing radiotracer is one of the most sensitive and accurate method for bioaccumulation, biodistribution and biokinetic study. Here, we developed a preparation method for radioiodinated polyvinyl chloride (PVC) as a potential radiotracer of microplastics. Iodine-131 (131I) as a potential radiotracer for microplastic was used in this experiment (activity of 98.05-221.63 MBq). The 131I-PVC was prepared using the Conant-Finkelstein reaction with a solvent combination of phosphate buffer (B), acetone (A), and tetrahydrofuran (T). Such preparation method resulted in spherical 131I-PVC with sizes ranging from 608.6 to 5457.0 nm. Our study showed that acetone is the most suitable solvent for the radioiodination process, resulting in a stable 131I-PVC for up to six days.

Abstract
Purpose The application of contrast and tracing agents is essential for lung imaging, as indicated by the wide use in recent decades and the discovery of various new contrast and tracing agents. Different aerosol production and pulmonary administration methods have been developed to improve lung imaging quality. This review details and discusses the ideal characteristics of aerosol administered via pulmonary delivery for lung imaging and the methods for the production and pulmonary administration of dry or liquid aerosol. Methods We explored several databases, including PubMed, Scopus, and Google Scholar, while preparing this review to discover and obtain the abstracts, reports, review articles, and research papers related to aerosol delivery for lung imaging and the formulation and pulmonary delivery method of dry and liquid aerosol. The search terms used were "dry aerosol delivery", "liquid aerosol delivery", "MRI for lung imaging", "CT scan for lung imaging", "SPECT for lung imaging", "PET for lung imaging", "magnetic particle imaging", "dry powder inhalation", "nebuliser", and "pressurised metered-dose inhaler". Results Through the literature review, we found that the critical considerations in aerosol delivery for lung imaging are appropriate lung deposition of inhaled aerosol and avoiding toxicity. The important tracing agent was also found to be Technetium-99m (99mTc), Gallium-68 (68Ga) and superparamagnetic iron oxide nanoparticle (SPION), while the essential contrast agents are gold, iodine, silver gadolinium, iron and manganese-based particles. The pulmonary delivery of such tracing and contrast agents can be performed using dry formulation (graphite ablation, spark ignition and spray dried powder) and liquid aerosol (nebulisation, pressurised metered-dose inhalation and air spray). Conclusion A dual-imaging modality with the combination of different tracing or contrast agents is a future development of aerosolised micro and nanoparticles for lung imaging to improve diagnosis success.

Abstract
Cobalt metal is considered as an essential trace element for the animals. Present investigation was undertaken in the peri-urban area to analyze the cobalt availability in animal food chain by using different indices. Cow, buffalo and sheep samples along with forage and soil samples were collected from the three different sites of District Jhang and analyzed through atomic absorption spectrophotometer. Cobalt values differed in soil samples as 0.315-0.535 mg/kg, forages as 0.127-0.333 mg/kg and animal samples as 0.364-0.504 mg/kg. Analyzed cobalt concentration in soil, forage and animal samples was found to be deficient in concentration with respect to standard limits. Soil showed the minimum cobalt level in Z. mays while maximum concentration was examined in the forage C. decidua samples. All indices examined in this study has values lesser than 1, representing the safer limits of the cobalt concentration in these samples. Enrichment factor (0.071-0.161 mg/kg) showed the highly deficient amount of cobalt enrichment in this area. Bio-concentration factor (0.392-0.883) and pollution load index (0.035-0.059 mg/kg) values were also lesser than 1 explains that plant and soil samples are not contaminated with cobalt metal. The daily intake and health risk index ranged from 0.00019-0.00064 mg/kg/day and 0.0044-0.0150 mg/kg/day respectively. Among the animals, cobalt availability was maximum (0.0150 mg/kg/day) in the buffaloes that grazed on the C. decidua fodder. Results of this study concluded that cobalt containing fertilizers must be applied on the soil and forages. Animal feed derived from the cobalt containing supplements are supplied to the animals, to fulfill the nutritional requirements of livestock.

Type of funding sources: None.
Background
Cardioprotective therapies represent an important avenue to reduce these limiting toxicities, including serious heart failure (HF) events. However, due to conflicting isolated reports, the true efficacy and optimal cardioprotective therapy at the time of anticancer treatment initiation is unclear. Therefore, we undertook a network meta-analysis to elucidate the most effective therapies at cardiotoxic HF prevention.
Purpose
To determine the efficacy, and optimal cardioprotective strategy in patients receiving cardiotoxic chemotherapies.
Methods
Leveraging the MEDLINE/Pubmed, CENTRAL, and clinicaltrials.gov databases, we identified all randomized controlled trials (RCTs) investigating cardioprotective therapies from inception to November 2021. Eligible cardioprotective classes included ACEIs, ARBs, Beta-blockers, dexrazoxane (DEX), statins, and mineralocorticoid receptor antagonists (MRA). The primary endpoint was the prevention of new-onset HF. The secondary outcomes were the mean difference in left ventricular ejection fraction (LVEF) change, the incidence of hypotension, and all-cause mortality. Network meta-analyses were used to assess the cardioprotective effects of each therapy to deduce the most effective therapies. Both analyses were undertaken using a Bayesian random-effects model to estimate risk ratios (RR) and 95% credible intervals (95% CrI).
Results
Overall, from 726 articles, 39 studies evaluating 5,931 participants (38.0±19.1 years, 72.0% females) were identified. Over a median follow-up of 6 months, use of any cardioprotective strategy was associated with a significant reduction in new-onset HF (RR:0.32; 95% CrI:0.19-0.55), improved LVEF (mean difference: 3.92%; 95% CrI:2.81-5.07), and increased hypotension (RR:3.27; 95% CrI:1.38-9.87); there was no difference in mortality (RR:1.03; 95% CrI:0.84-1.22). Based on the median risk of incident HF in the control groups being 3.28%, the number need to treat (NNT) for "any" cardioprotective therapy to prevent one incident HF event was 45 patients. For dexrazoxane and neurohormonal agents, the median NNT was 36 and 53 patients, respectively. In this network analysis, dexrazoxane was most effective at HF prevention [Surface Under the Cumulative Ranking curve (SUCRA): 81.47%] and MRA most effective at preserving LVEF (SUCRA: 99.22%). ARBs most greatly increased hypotension (RR:7.20; 95% CrI:2.46-26.94).
Conclusion
Cardiotoxicity remains a challenge for cancer patients requiring life-saving cancer therapies. The initiation of a cardioprotective strategy reduces incident HF. Additional head-to-head trials are needed to confirm the optimal preventative strategy.

Abstract
Abstract
Background
Despite free vaccination services, gaps in information access impede immunization uptake in low and middle-income countries (LMICs), including Pakistan. We developed Bablibot (Babybot), a local-language, text-based chatbot to connect caregivers with immunization-related information in real-time, and evaluated its feasibility and acceptability in resolving immunization-related queries among Karachi's low-income communities.
Methods
We developed Bablibot using Natural Language Processing (NLP), Machine Learning, and Human in the Loop features. We conducted a sequential mixed-methods pilot in Karachi where caregivers were recruited when visiting selected immunization centers for any childhood vaccine except Measles 2 (last vaccine visit) or were informed through targeted text messages. We assessed Bablibot's feasibility and acceptability through user-engagement metrics and thematic analysis of qualitative interviews conducted with 20 pilot participants.
Results
Between March 9, 2020 and April 15, 2021, Bablibot accrued 677 users and participated in 874 conversations. Of 2,202 pilot-enrolled caregivers, 210 (10%) interacted with the bot; other 467 users were not pilot participants. Most queries were about due dates (25%; 221/874), delaying vaccination (17%; 146/874), or side-effect management (16%;137/874). The conversations now constitute a valuable training database for future local-language bots. Over 90% (277/307) of responses to text-based exit surveys indicated user satisfaction. Qualitative analysis showed caregivers appreciate Bablibot's convenience, reliability, and responsiveness.
Conclusions
Our results demonstrate the feasibility and acceptability of local-language NLP chatbots in providing immunization information. Text-based chatbots can minimize workload on helpline operators, in addition to quickly resolving queries that otherwise lead to delay or default. Bablibot's conversation data provides learning infrastructure for future health-related bots.
Key messages
An AI-based NLP chatbot is a feasible and acceptable intervention for providing immunization-related information to large number of caregivers 24/7 in limited resource setting. By serving as a remote, low-cost and confidential bi-directional channel, chatbots can address gaps in information access, especially for women, and have long term impact on immunization uptake.

Abstract
Intelligent Tutoring System (ITS) has been widely used in supporting personal learning. However, there is an aspects that have not become focus in ITS, namely immersive. This research proposes an Immersive Intelligent Tutoring (IIT) model based on Bayesian Knowledge Tracing (BKT) for determining the learner’s characteristics and learning content delivery strategies using genetic algorithms. The model uses remedial learning with a faded worked-out example. This study uses a 3-Dimensional Virtual Learning Environment (3DMUVLE) that implements immersive features to increase intrinsic motivation. This model was built using a client / server architecture. The server side component uses the MOODLE, the client side component uses OpenSim and its viewers, and the middleware component uses the Simulation Linked Object Oriented Dynamic Learning Environment (SLOODLE). Model testing is performed on user acceptance using a combination of Technology Acceptance Model (TAM) and Hedonic-Motivation System Adoption Model (HMSAM) and the impact of the model in learning using statistical test. The results showed 83% of the learners felt happy with the learning. Meanwhile, the evaluation of the impact on learning outcomes shows that the use of this model is significantly different from traditional learning.

Abstract
Abstract
Background
The walls across hospital wards are cluttered with posters, which, in some places, are peeling and staining with the years. Hospital management and well intention ward users dictate these displays, however their effectiveness in delivering essential information is rarely measured. We undertook a survey to establish: a) Whether posters are effective, b) What information ward users want, c) How they want information to be delivered.
Methods
100 participants (68 staff and 32 patients’ relatives) were surveyed across three 28 bedded wards for older people. They had to recall as many posters as possible then identify useful posters from a current list. They were asked about unmet information needs, other media that they would utilise and alternative uses for ward walls. Interventions were made on one ward based on initial findings: 1. An ‘Information for Relatives’ board was created, 2. A mural was installed. 20 relatives were asked to complete an anonymous form reviewing the board.
Results
Only 23% of participants were able to recall at least 3 posters. 34% could not find a single useful topic among the current posters. The most popular unmet information needs, among many, were ‘the discharge pathway’, ‘delirium’ and ‘falls’. Most participants said they would engage with alternative information media, suggesting leaflets, email and websites. A quarter felt walls should be for artwork, not posters. The ‘Information for Relatives’ board was well received. In the second survey, new unmet information needs were uncovered and, despite the new mural, 45% called for more paintings still.
Conclusions
Most people do not read the information on the walls on hospital wards. An appetite exists for alternative media. Paintings were earnestly called for at every point; a comforting ward environment should be part of the holistic care we aim to offer, especially for older patients.

The maximum biodiesel yield of 83% was obtained by base catalyzed transesterification process under optimum operating conditions of methanol to oil ratio of 15:1, reaction temperature of 150 °C, reaction time of 5 h and catalyst loading of 3.5%. The synthesized catalyst and biodiesel were characterized for their structural features and chemical compositions using various state-of-the-art techniques, including x-ray diffraction, scanning electron microscopy, energy dispersive x-ray spectroscopy, Fourier transform infrared spectroscopy, nuclear magnetic resonance (1H, 13C) and gas chromatography-mass spectroscopy. The fuel properties of the biodiesel were estimated including kinematic viscosity (4.36 cSt), density (0.8312 kg/L), flash point (72 °C), acid value (0.172 mgKOH/g) and sulphur content (0.0002 wt.%). These properties were compared and found in good agreement with the International Biodiesel Standards of American (ASTM-951, 6751), European Committee (EN-14214) and China GB/T 20828 (2007). The catalyst was re-used in five consecutive transesterification reactions without losing much catalytic efficiency. Overall, non-edible Raphnus raphanistrum L.. seed oil and Cu doped MMT clay catalyst appeared to be highly active, stable, and cheap contenders for future biofuel industry. However, detailed life cycle assessment (LCA) studies of Raphnus raphanistrum L. seed oil biodiesel are highly recommended to assess the technical, ecological, social and economic challenges.

Abstract
Abstract
Background
Randomized trials have shown improvement in hard clinical end points when catheter ablation (CA) was employed as a management strategy for certain atrial fibrillation (AF) patients with heart failure and reduced ejection fraction (HFrEF). We sought to determine real world data on mortality and complications after utilization of CA in such patients.
Methods and results
Data were derived from National Inpatient Sample from January 2008 to August 2015. Patients were identified using the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes. Baseline characteristics and outcomes were compared among AF and HFrEF patients undergoing CA or not. Propensity matching was done to mitigate selection bias and balance confounding variables. Various CA related complications were assessed. Logistic regression was done to determine predictors of mortality in our study cohort. A total of 2,569,919 patients were enrolled and out of these approximately 7773 patients underwent CA. Mortality was significantly better in CA group in both unmatched (1.2% vs. 4.9%, p<0.01) and propensity matched cohorts (1.2% vs. 3.6%, p<0.01). Overall complication rate was 10.2% in CA cohort and were primarily cardiac and neurological in origin. In regression analysis, CA remains a strong predictor of reduced mortality (OR 0.301, 95% CI 0.184–0.494).
Conclusion
CA is associated with improved mortality in admitted AF patients with concomitant HFrEF. Overall complication rate after CA was modest at 10.2%.

Abstract
Abstract
Background
The Integrated Management of Childhood Illnesses (IMCI) strategy was launched by WHO and partners in 1995 to reduce child mortality by enhancing frontline health workers' (FHWs) ability to diagnose and manage childhood illnesses, and strengthen overall health systems. However, although IMCI is associated with decreased child mortality, numerous studies have shown its impact has been limited due to persistent barriers to implementation.
Methods
We developed a digitized version of IMCI (eIMCI) using Android technology to overcome implementation problems, including poor protocol compliance, lengthy trainings, paper-based data collection, and gaps in the referral system. The feasibility and efficacy of eIMCI was assessed through a mixed-methods pilot study encompassing baseline and end-line surveys, interviews, and Focus Group Discussions, in a low-resource rural district of Punjab, Pakistan. During the 8 weeks of deployment, a total of 1,978 children were enrolled in the eIMCI application by 10 participating FHWs, and 47 electronic referrals were generated.
Results
Preliminary outcomes showed reduced disease occurrence (for example, diarrhea decreased from 48% at baseline to 29% at endline), increased adherence to IMCI protocol, and strengthened health system linkages (facility referrals increased from 5% at baseline to 45% at endline). FHWs reported enhanced performance, as well as an improved community response to their services.
Discussion
Indicating the feasibility and efficacy of eIMCI deployment in a low-resource setting, evidence from the pilot demonstrates the benefit of digitizing the IMCI protocol. eIMCI is a digital health solution with the potential to significantly reduce child mortality and improve service delivery and performance of FHWs.
Key messages
eIMCI is a feasible solution for the implementation of IMCI strategy in developing countries and demonstrates increased compliance and enhanced performance by the frontline health workers. Implementation of eIMCI can result in a significant reduction in child morbidity and mortality via timely referrals of patients and reduced disease occurrence.

Abstract
Abstract
Introduction
Older people are likely to have more CT head scans given their multiple co- morbidities, being on anticoagulants, and increased falls. The aims of this quality improvement project (QIP) were to identify the number of patients who had CT head scan, the reason/indication of it, the number of patients who had new finding/s on it, actions taken on new findings, and whether the management plan was altered because of the CT scan.
Methods
Medical notes and CT head scan reports of all patients admitted to the Health Care of Older People department from April to September 2018 were reviewed to evaluate the indications of CT head scans, new findings, and management plans following the findings.
Results
461 (10.7%) out of the 4323 patients discharged from the healthcare of older people department during April to September 2018 had CT head scans during admission. Frequent indications for CT head scans included delirium, falls and head injury. Only 46 (9.9%) patients had new finding/s on the CT head scan, and action was taken on 26 (56.5%) of these patients. The CT head scan changed the management plan of only 17 (3.6%) patients. Please see Table for more details.
Conclusions
By using our clinical judgement, following NICE guidelines on head injuries, educating our colleagues on the criteria for requesting a CT head scan, taking collateral histories about patients’ cognition and ascertaining the mechanism of fall, we can lessen the financial burden on the NHS and minimise the radiation exposure to our patients.

Abstract
Technetium-99m (99mTc), a daughter radionuclide of molybdenum-99 (99Mo), is the most widely used radiodiagnostic agent due to its ideal characteristics. The separation of this radionuclide from 99Mo is commonly performed using alumina. However, a new production method of this radionuclide, which employs a low specific activity 99Mo, makes alumina no longer suitable as separation material. This study aims to develop novel alumina using a facile solid-state reaction for 99Mo/99mTc generator system. The SS-alumina was synthesized from aluminium nitrate nonahydrate and ammonium bicarbonate without solvent. The resulted SS-alumina was then analyzed by FTIR and BET method. 99Mo adsorption and 99mTc releasing study on a series of pH were also performed. FTIR study revealed that the resulting material was Al2O3 with a surface area of 237.65 m2/g. The adsorption capacity, 99mTc yield, 99Mo breakthrough, and alumina breakthrough were 76.06 mg Mo/g alumina, 80.31%, 56.5 µCi/mCi 99mTc, and less than 5 mg/mL, respectively. The elution profile shows a high activity of 99mTc in 2nd and 3rd fraction. It is concluded that the SS-alumina shows good performance as adsorbent material for separation of a 99Mo/99mTc and further work is now underway.

Abstract
Newcastle disease (ND) and avian influenza (AI) are economically important infectious diseases of poultry. Sometime, concomitant secondary viral/or bacterial infections significantly alters the pathobiology of ND and AI in poultry. As of now, the disease patterns and dynamics of co-infections caused by ND virus (NDV, genotype XIII) and Low Pathogenic AI viruses (LPAI, H9N2) are explicitly elusive. Thus, we examined the clinicopathological disease conditions due to these two economically important viruses to understand the complex disease outcomes by virus-virus interactions in vaccinated flocks. The findings of clinicopathological and molecular investigations carried on 37 commercial ND vaccinated poultry flocks revealed simultaneous circulation of NDV and AIV in same flock/bird. Further, molecular characterization of hemagglutinin (HA) and neuraminidase (NA) genes confirmed that all the identified AIVs were of low pathogenicity H9N2 subtype and fusion (F) gene analysis of detected NDVs belong to NDV class II, genotype XIII, a virulent type. The NDV and H9N2 alone or co-infected flocks (NDV + LPAI) exhibit clinical signs and lesions similar to that of virulent NDV except the degree of severity, which was higher in H9N2-NDV co-infected flocks. Additionally, avian pathogenic E. coli and mycoplasma infections were detected in majority of the ailing/dead birds from the co-infected flocks during progression of the clinical disease. Overall, the findings highlight the multi-factorial disease complexity in commercial poultry and suggest the importance of NDV genotype XIII in intensifying the clinical disease in vaccinated birds.

Abstract
Canine parvoviruses (CPV) exist as antigenic variants with varying frequencies and genetic variabilities across the globe. Given the endemicity and high prevalence in Pakistan, we characterized the CPVs originating from dogs-population to elucidate viral diversity and evolution. Fecal samples from clinically diseased pups (n = 17) of different breeds and age (2-6 months) were processed for hemagglutination assay (HA), and later for partial amplification of VP2 gene sequence and amino acid analysis. A total of 11 samples (64.71%) were found positive both in hemagglutination and PCR assays. Phylogenetic and evolutionary analysis demonstrated higher genetic heterogeneity in studied strains and constituted seven clusters within the CPV-2a group, however, they shared high level of identity with Chinese strains. Further studies are necessary to elucidate genetic analysis and epidemiology of CPV variants across a wide geographical area of the country.

Abstract
Analysis of 108 cases of Neonatal Tetanus by using a scoring system (Tjandra et al., 1974) revealed that 18 patients belonged to Grade I with a mortality rate of 5.6%; 43 belonged to Grade II with a mortality nate of 58.1%; and 47 belonged to Grade III with 91.5% mortality. The differences of mortality between the 3 groups are statistically significant. Mortality rate of 1973 was the lowest (50%) compared to that of 1972 (75%); 1974 (72.2%) and 1975 (61.4%). However, the number of patients belonging to Grade I in 1973 was the highest, 36.4%; whereas that of 1972 was 16.7%; 1974 was 11.1% and 1975 was 9.1 %. Classification of severity in Neonatal Tetanus is therefore, not only important for selecting a "treatment of choice" by comparing mortality rates of those having the same grade of severity, but may be also very useful in determining the method of treatment for different levels of severity.

Abstract
Multiple species of Colletotrichum can cause bitter rot disease of apple, but the identities and relative representation of the species causing the disease in Kentucky are unknown. In total, 475 Colletotrichum isolates were collected from diseased apple fruit in 25 counties and characterized both morphologically and by using various molecular approaches. Multigene sequence analyses revealed that sample isolates belonged to several newly erected species within the Colletotrichum acutatum and C. gloeosporioides species complexes. The isolates were identified as C. fioriniae and C. nymphaeae, which reside within the C. acutatum species complex, and C. siamense, C. theobromicola, and C. fructicola, which are placed within the C. gloeosporioides species complex. C. fioriniae was the most common species causing bitter rot in Kentucky, comprising more than 70% of the isolates. Infectivity tests on detached fruit showed that C. gloeosporioides species-complex isolates were more aggressive than isolates in the C. acutatum species complex. However, isolates within the C. acutatum species complex produced more spores on lesions compared with isolates within the C. gloeosporioides species complex. Aggressiveness varied among individual species within a species complex. C. siamense was the most aggressive species identified in this study. Within the C. acutatum species complex, C. fioriniae was more aggressive than C. nymphaeae, causing larger, deeper lesions. Apple cultivar did not have a significant effect on lesion development. However, Colletotrichum spp. produced more spores on 'Red Stayman Winesap' than on 'Golden Delicious'. Fungicide sensitivity tests revealed that the C. acutatum species complex was more tolerant to thiophanate-methyl, myclobutanil, trifloxystrobin, and captan compared with the C. gloeosporioides species complex. The study also revealed that mycelial growth of C. siamense was more sensitive to tested fungicides compared with C. fructicola and C. theobromicola. These research findings emphasize the importance of accurate identification of Colletotrichum spp. within each species complex, because they exhibit differences in pathogenicity and fungicide sensitivity.

Abstract
Peste des petits ruminants (PPR) is an acute viral disease of small ruminants. The disease was first reported in Tanzania in 2008 when it was confined to the Northern Zone districts bordering Kenya. The present study was carried out to confirm the presence of PPR virus (PPRV) in Tanzania and to establish their phylogenetic relationships. Samples (oculonasal swabs, tissues and whole blood) were obtained from live goats with clinical presentation suggestive of PPR and goats that died naturally in Ngorongoro (Northern Tanzania) and Mvomero (Eastern Tanzania) districts. The clinical signs observed in goats suspected with PPR included fever, dullness, diarrhea, lacrimation, matting of eye lids, purulent oculonasal discharges, cutaneous nodules, erosions on the soft palate and gums and labored breathing. Post mortem findings included pneumonia, congestion of the intestines, and hemorrhages in lymph nodes associated with the respiratory and gastrointestinal systems. PPRV was detected in 21 out of 71 tested animals using primers targeting the nucleoprotein (N) gene. Phylogenetic analysis, based on the N gene, indicated that PPRV obtained from Northern and Eastern Tanzania clustered with PPRV strains of Lineage III, together with PPRV from Sudan and Ethiopia. The findings of this study indicate that there are active PPRV infections in Northern and Eastern Tanzania, suggesting risks for potential spread of PPR in the rest of Tanzania.

Abstract
Classical swine fever (CSF) is a highly contagious and the most important disease of pigs worldwide.CSF is enzootic in pig herds in India and continues to cause huge economic losses to pig farmers. Nearly 40% of the total pig population of India is present in the north-eastern (NE) states where pig husbandry plays an important role in the socio-economic development. Pigs reared in the backyards are the only source of livelihood for a majority of poor tribal population in the region. Hardly any CSF vaccination is currently being undertaken in the unorganized pig farming in the NE region due to economic reasons and vaccine unavailability. A thorough understanding of the current epidemiological status of CSF is essential for the effective control of the disease in the NE region. Hence, we carried out molecular characterization of CSFV isolates from field outbreaks during 2011-2012 in the entire north-eastern region of India to establish the genetic groups of prevalent CSF viruses in the region. A total of 17 CSFV isolates obtained from different parts of the NE region were characterized by comparing the sequences of three partial genomic regions of the virus, that is 150 nt of 5' UTR, 190 nt of E2 and 409 nt of NS5B. Of the 17 CSFV isolates, 15 isolates belonged to 1.1 (88.2%) and two isolates (11.8%) belonged to 2.2 subgenogroup. The genogroup 2.2 CSFV were associated with outbreaks in Arunachal Pradesh that shares international borders with Bhutan, Myanmar and China. Genogroup 2.2 CSFV isolated in the present study shared high level of sequence similarity with 2.2 viruses form China, raising the possibility of virus incursion from this region. In summary, we found a continued predominance of 1.1 subgroup and an emergence of 2.2 subgroup CSFV in NE region of India.

Abstract
Isolates of peste des petits ruminants virus (PPRV) can be segregated genetically into four lineages. For decades, lineages I-III have been reported across Africa whilst lineage IV has predominantly circulated across Asia. However, the lineage distribution is currently changing in Africa. Importantly, full genome sequence data for African field isolates have been lacking. Here, we announce the first complete genome sequence of a field isolate of peste des petits ruminants virus (PPRV) from East Africa. This isolate was derived from the intestine of a goat suffering from severe clinical disease during the 2010 outbreak in Ethiopia. The full genome sequence of this isolate, PPRV Ethiopia/2010, clusters genetically with other lineage IV isolates of PPRV, sharing high levels of sequence identity across the genome. Further, we have carried out a phylogenetic analysis of all of the available African partial N gene and F gene PPRV sequences to investigate the epidemiology of PPRV with a focus on the emergence of different lineages of PPRV in Africa.

Abstract
Considering the 'One Health' principles, the links between animal and human health are very strong. Both domestic and wild animals are sources of infectious agents that cause diseases in humans. Poor animal health may also indirectly affect human health, through reduced access to food. A large number of infectious diseases of animals, the transboundary animal diseases, spread rapidly across borders. Robust and accurate diagnostic assays are needed to detect the infectious agents rapidly and to limit their spread. A large arsenal of novel assays has been developed during the last three decades, with a tremendous impact on the detection of infectious agents. The new diagnostic methods are mostly laboratory-based and expensive, requiring sophisticated equipment and special skills. However, rapid and cheap field-based assays have also been developed. Herein, the authors give several examples of the development of novel assays, with special focus on the 'One Health' principles.

Abstract
Peste des petits ruminants (PPR) is an endemic disease of small ruminants, and vaccination has been the method of control but outbreaks are continuously occurring in Pakistan. The following study presents a detailed investigation of an outbreak, suspected to be PPR, probably introduced by PPRV-infected sheep and goats from Sindh Province (north-west) to Punjab Province (central) of Pakistan during the flood relief campaign in 2011. A total of 70 serum samples from 28 different flocks were tested with competitive ELISA (H antibodies), which detected 24 (34.2%) samples positive for PPRV antibodies. Nasal swabs and faeces were tested with immunocapture ELISA (N antigen), which detected 18 (25.7%) samples positive for PPRV antigen. The RNA detected positive (n = 28, 40%) using real-time PCR was subjected to conventional PCR for the amplification of the fusion and nucleoprotein genes. Sequencing of both genes and subsequent phylogenetic analysis indicated the grouping of all the sequences to be in lineage IV along with other Asian isolates of PPRV. However, sequences of both genes were divided into two groups within lineage IV. One group of viruses clustered with previously characterized Pakistani isolates, whereas the other group was distinctly clustered with isolates from the Middle East or India. The sequence identity indicated the introduction of at least one population of PPRV from a different source and circulation in the local flocks of small ruminants, which emphasized the need to obtain health clearance certificate before movement of animals. The results of this study provide baseline data for the genetic characterization of different PPRV populations in Pakistan.

Abstract
Newcastle disease (ND) is a fatal and contagious disease that poses a constant threat to the poultry industry around the globe. Due to the complex clinico-pathological picture and high genetic variability, the efficient diagnosis of NDV strains is a challenge. In an emerging wave of ND in the north of Pakistan, samples from six outbreaks in commercial poultry and two from healthy backyard poultry flocks were screened for NDV. A real-time PCR based on the fusion and polymerase genes of NDV detected all six isolates whereas a validated real-time PCR based on the matrix gene failed to detect any of these isolates, most likely due to substantial mismatches in the probe-binding site. All isolates have shown ICPI and MDT values similar to the velogenic form of NDV strains. The cleavage site in the F protein was found to be (112)RRQKR↓F(117), typical of virulent NDV. Phylogenetic reconstruction, based on fusion and matrix genes, provided enough evidences to consider these isolates as a new subgenotype within genotype VII. This study raised concerns about the genetic variability of NDV circulating in Pakistan, and sensitivity of the assays for the detection of the NDV isolates in clinical samples.

Abstract
Peste des Petits Ruminants (PPR) is an important viral disease of small ruminants and is endemic in Pakistan. In the following study, samples from two outbreaks of PPR in goats have been subjected to laboratory investigations. The Peste des Petits Ruminants virus (PPRV) genome was detected using both conventional and real-time PCR. Genetic characterization of the local PPRV field isolates was conducted by sequencing 322 bp of the fusion (F) gene and 255 bp of the nucleoprotein (N) gene. The phylogenetic tree based on the F gene clustered samples from both outbreaks into lineage 4 along with other Asian isolates, specifically into subcluster 1 along with isolates from Middle East. Analysis of N gene revealed a different pattern. In this case, the Pakistani samples clustered with Chinese, Tajikistani and Iranian isolates, which probably represents the true geographical pattern of virus circulation. This is the first report presenting the phylogenetic tree based on N gene as well as performing a parallel comparison of the trees of F and N gene together from Pakistani isolates. The results of this study shed light on the PPRV population in Pakistan and emphasize the importance of using molecular methods to understand the epidemiology. Such understanding is essential in any efforts to control the number and impact of outbreaks that are occurring in endemic countries such as Pakistan, especially in the current scenario where OIE and FAO are eager to control and subsequently eradicate PPR from the globe, as has been achieved for Rinderpest.

Abstract
The prevalence of gastrointestinal nematodes was studied in 143 (80 male and 63 female) domestic pigeons. Faecal samples were collected to determine the gastrointestinal nematodes of domestic pigeons through qualitative and quantitative faecal examinations. A total of 48 (male 33 and 25 female) naturally infected domestic pigeons were divided into G1 (albendzdole) and G2 (fenbendazole) treatment-groups along with one control group (C). The overall prevalence of gastrointestinal nematodes was 40.5% (58/143) in domestic pigeons. Likewise, the prevalence of gastrointestinal nematodes in males and females was found 41.3% (33/58) and 39.7% (25/58) respectively. The overall prevalence of Capillaria obsignata and Ascaridia columbae was found to be 67.2% and 32.8%, respectively. The prevalence of C. obsignata and A. columbae in males was 72.7% (24/33) and 27.8% (9/33) and in females was 60% (15/25) and 40% (10/25), respectively. There was no significant sex related difference seen in the prevalence of C. obsignata (p>0.56) and A. columbae (p>0.40) in domestic pigeons, respectively. The overall efficacy of albendazole and fenbendazole was calculated to be 66% and 71%. A remarkable significant difference (p<0.05) was observed in eggs per gram before and after treatment in both G1 and G2 treated-groups. The efficacy of fenbendazole was found to be more significant (p<0.02) than albendazole.

Abstract
Occupational exposure data of workers due to external sources of radiation in various medical practices such as nuclear medicine (NM), radiotherapy and diagnostic radiology (DR) in Pakistan were collected and analysed. Whole-body doses of workers were measured by film badge dosimetry technique during 2003-2007. Annual average effective dose in NM, radiotherapy and DR varied in the range of 1.39-1.80, 1.05-1.45 and 1.22-1.71 mSv, respectively, during 2003-2007. These values are quite low and well below the annual limit of 20 mSv averaged over a period of 5 consecutive years. Nobody received the radiation dose >50 mSv in any single year over a period of 5 consecutive years; therefore, no overexposure case has been detected. Decreasing trend of annual average dose values in aforementioned categories of work during 2003-2007 indicates the improvement of radiation protection status in medical field in Pakistan.

Abstract
The disease early warning system (DEWS) was introduced in the immediate aftermath of the 2005 earthquake in Pakistan, with the objective to undertake prompt investigation and mitigation of disease outbreaks. The DEWS network was replicated successfully during subsequent flood and earthquake disasters as well as during the 2008-09 internally displaced persons' crisis. DEWS-generated alerts, prompt investigations and timely responses had an effective contribution to the control of epidemics. Through DEWS, 1360 reported alerts during 2005-09 averted the risk of disease outbreaks through pre-emptive necessary measures, while the 187 confirmed outbreaks were effectively controlled. In the aftermath of the disasters, DEWS technology also facilitated the development of a disease-surveillance system that became an integral part of the district health system. This study aims to report the DEWS success and substantiate its lead role as a priority emergency health response intervention.

Abstract
A portable gamma radiation monitor has been designed and developed. The monitor can be used effectively in the dose range from 0.07 to 500 mGy/h due to gamma rays of energy greater than 65 keV. The monitor overestimated radiation doses and the uncertainty in the measured dose rate has been found to be < or = 30%. The response of the monitor can be considered isotropic within an acceptable error of +/-30%. Provision has also been added to use the monitor as an installed radiation monitor. In installed mode, it can be operated from a remote location up to 1 km and the timing history can be stored on a personal computer.

Abstract
BACKGROUND Tuberculosis, being an infectious disease, carries a risk of infection to contacts attending tuberculous patients. This study was conducted to evaluate the risk for household contacts of tuberculous patients as compared to non-contacts. The study was conducted at PGMI, Gulab Devi Hospital and Defence Housing Authority Lahore. The study included 120 household contacts and 80 non-contacts. METHODS A Cross sectional study for evaluation of antituberculous antibodies levels by ELISA method in two groups; Mantoux positive household contacts 49, Mantoux negative household contacts 71 and normal healthy persons 'non contacts' 80. Routine Haematological investigations like HB, TLC and ESR were done by conventional methods and all the sera of 200 subjects included in the study were tested for IgM, IgG and IgA anti tuberculous antibodies by enzyme linked immunosorbant assay (ELISA). Purified protein derivative 0.1 ml containing 5 TU was injected intradermally. The test was read after 72 hours by measuring the induration around injection site of forearm. RESULTS There was no difference in the average age of the household contacts and non-contacts. The complaints of pyrexia, night sweats and weight loss were more in house hold contacts as compared to non-contacts. The awareness about BCG vaccination was equal in both. There were 49 contacts with positive Mantoux test while negative Mantoux test was found in 71 contacts. There were only three Mantoux positive among eighty non-contacts. There was no significant difference in the presence of IgM among household contacts as compared to non-contacts. However both IgG and IgA were present in significantly higher number of household contacts compared to non-contacts. CONCLUSION Household contacts of patients suffering from active pulmonary tuberculosis have more chances of being infected with Mycobacterium tuberculosis as compared to the healthy non-contact, as shown by the higher levels of antituberculous antibodies & positivity of Mantoux test.

Abstract
A model has been developed that can be used to determine the phases of sensitivity to photoperiod for seedlings subjected to reciprocal transfers at regular intervals between long (LD) and short day (SD) conditions. The novel feature of this approach is that it enables the simultaneous analysis of the time to flower and number of leaves below the inflorescence. A range of antirrhinum cultivars were grown, all of which were shown to be quantitative long-day plants. Seedlings were effectively insensitive to photoperiod when very young (juvenile). However, after the end of the juvenile phase, SD delayed flowering and increased the number of leaves below the inflorescence. Plants transferred from LD to SD showed a sudden hastening of flowering and a decrease in leaf number once sufficient LD had been received for flower commitment. Photoperiod had little effect on the rate of flower development. The analysis clearly identified major cultivar differences in the length of the juvenile phase and the photoperiod-sensitive inductive phase in both LD and SD.

Abstract
BACKGROUND A study was conducted at Ayub Teaching Hospital, Abbottabad, a tertiary hospital, to know whether drugs are prescribed rationally keeping in mind indications, interactions, contraindications, proper dosage and economy of the patient. METHODS The study was a descriptive case study. Records of 200 patients admitted in various units of the hospital were analysed by a panel of pharmacologists and conclusions drawn. RESULTS It was found that only 52% of patients receive prescriptions that were rationale in all aspects. Where as in rest of the patients the rationale could be challenged. CONCLUSION This study stresses the need for more concentrated and dedicated effort towards prescription of medicines.

Abstract
Sodium-dependent transporters regulate extracellular glutamate in the CNS. Recent studies suggest that the activity of several different neurotransmitter transporters can be rapidly regulated by a variety of mechanisms. In the present study, we report that pre-incubation of primary 'astrocyte-poor' neuronal cultures with glutamate (100 microM) for 30 min nearly doubled the V(max) for Na(+)-dependent accumulation of L-[(3)H]-glutamate, but had no effect on Na(+)-dependent [(3)H]-glycine transport. Pre-incubation with glutamate also increased the net uptake of non-radioactive glutamate, providing evidence that the increase in accumulation of L-[(3)H]-glutamate was not related to an increase in intracellular glutamate and a subsequent increase in exchange of intracellular non-radioactive glutamate for extracellular radioactive glutamate. The glutamate receptor agonists, alpha-amino-3-hydroxy-5-methylisoxazole-4-propionate, quisqualate, and (1 S, 3R)-1-aminocyclopentane-1,3-dicarboxylic acid did not mimic the effect of pre-incubation with glutamate and the glutamate-induced increase was not blocked by receptor antagonists. However, compounds known to interact with the transporters, including L-aspartate, D-aspartate, L-(-)-threo-3-hydroxyaspartate (L-THA) and L-trans-pyrrolidine-2,4-dicarboxylate (L-trans-PDC), caused variable increases in transport activity and attenuated the increase induced by glutamate, suggesting that the increase is related to the interaction of glutamate with the transporters. Several studies were attempted to define the mechanism of this regulation. We found no evidence for increases in transporter synthesis or cell surface expression. Inhibitors of signaling molecules known to regulate other neurotransmitter transporters had no effect on this stimulation. Using a variety of cultures, evidence is provided to suggest that this substrate-induced up-regulation of glutamate transport is specific for the GLT-1 and GLAST subtypes and does not influence transport mediated by EAAC1. These studies suggest that the interaction of glutamate with some of the subtypes of glutamate transporters causes an increase in transport activity. Conceivably, this phenomenon provides an endogenous mechanism to increase the clearance of glutamate during periods of prolonged elevations in extracellular glutamate.

Abstract
OBJECTIVE To compare the results of Clostridium Difficile (CD) on culture with detection of C. difficile toxin by Enzyme Immunoassay (EIA) in the stool specimens of hospitalized patients with antibiotic associated diarrhoea (AAD). PATIENTS AND METHODS The study included 80 adult patients with AAD and 20 adult patients with non-AAD. Stool specimens of all these subjects were inoculated on cycloserine cefoxitin fructose agar and incubated anaerobically to isolate C. difficile. At the same time, all the stool specimens were tested for C. difficile toxin by EIA technique using cytoclone A and B kit manufactured by Cambridge Biotech Corporation, Worcester, Massachusette. RESULTS Out of 80 adult patients with AAD, thirty were females and fifty males. C. difficile was isolated on culture from stool specimen of 16 patients, while twenty-three stool specimens were positive for C. difficile toxin. From 20 control subjects, C. difficile was isolated from stool specimen of only one subject. No stool specimen from the controls was positive for toxin. CONCLUSION Diagnosis of CDAAD by culture is difficult and time consuming because of strict anaerobic nature of organism. Moreover, mere isolation of C. difficile on culture is not sufficient to establish the pathogenic role of these isolates. C. difficile toxin detection by EIA technique is a highly sensitive and specific method for diagnosis of CDAAD. Using this method, results are available in three hours time. Therefore, EIA is recommended for rapid diagnosis of CDAAD.

Abstract
Ameloblastoma is a histologically benign tumor derived from odontogenic apparatus. The tumor can infiltrate into surrounding tissues. Although it is benign, it presents symptoms of a malignant tumor, such as infiltration into the lungs, pleura, regional and distant metastases, orbit, base of skull, brain and has resulted in death. It also has a high incidence of recurrences, the existence of regional or distant metastasis, showing a microscopic pattern of ameloblastic carcinoma with cytologic features of an increasing nuclear/cytoplastic ratio, nuclear hyperchromatism, and the presence of mitosis. We report a study of 12 patients of ameloblastoma of the jaws between January 1992 and December 1996 consisting of 8 affected in the mandible and 4 in the maxilla. One patient with a tumor in the maxilla was excluded from this study, due to a different histological and clinical behaviour of the ameloblastoma.

Abstract
There are multiple subtypes of Na+-dependent glutamate transporters. Several studies suggest that EAAC1 and EAAT4 are expressed in neurons, while GLT-1 and GLAST expression is thought to be restricted to glia. In the present study, expression of GLT-1 and EAAC1 was examined in cultured rat hippocampal neurons using single cell mRNA amplification and immunocytochemistry with subtype specific antibodies. GLT-1 and EAAC1 mRNAs were observed in all neurons examined. Neuronal phenotype was confirmed in these cells by expression of neurofilament (NF-L) mRNA and absence of glial fibrillary acidic protein (GFAP) mRNA. EAAC1 immunoreactivity was observed in essentially all cells which expressed neuron specific enolase (NSE) and GLT-1 immunoreactivity was detected in the majority (approximately 90%) of NSE-positive cells. Consistent with the glial expression of GLT-1, GLT-1 immunoreactivity was also observed in NSE-negative cells. These studies provide evidence that GLT-1 expression is not intrinsically restricted to glial cells, but can occur in neurons under certain circumstances.
