Abstract
Toxoplasma gondii and Trichinella spp. are critical tissue-dwelling foodborne zoonotic parasites associated with pork consumption and pig rearing. Despite being a major pig-rearing region in the country, Northeastern India has not undergone any investigation regarding the presence of T. gondii and Trichinella spp. in pigs. Therefore, this study aims to determine the seroprevalence of T. gondii and Trichinella spp. and identify associated risk factors in pigs reared by tribal communities and small-holder livestock farmers in the northeastern region of India. In a cross-sectional serological survey, 400 pigs from 400 households across five northeastern states of India underwent testing for the seroprevalence of porcine toxoplasmosis and trichinellosis. Serum samples (80 from each state) were analyzed using commercially available ELISA assays. Data on backyard farm characteristics and various management aspects were collected, and risk factors linked with prevalence were analyzed through univariate and multivariate logistic regression analysis. The findings revealed that the apparent and true prevalence of anti-T. gondii antibodies were 45% (40.12-49.88, 95% CI) and 45.7% (40.7-50.69, 95% CI), respectively. As for anti- Trichinella antibodies, both the apparent and true prevalence were 0.75% (-0.1-1.6, 95% CI). The univariate and multivariate analyses indicated that age above 24 months (OR 7.20, 95% CI 2.45-23.71), exposure to cats (OR = 5.87, 95% CI 2.55-14.05), and farms operating for breeding purposes (OR = 5.60, 95% CI 3.01-11.04) were significant risk factors associated with the seroprevalence of T. gondii. This study marks the initial documentation of the seroprevalence of T. gondii and Trichinella spp. in pigs reared by tribal communities in Northeastern India. The results emphasize the significance of these parasites as foodborne zoonotic threats in the region, potentially posing substantial public health risks, especially within tribal and rural communities. The insights derived from this research could be valuable in formulating targeted preventive and control strategies against T. gondii and Trichinella spp. in pigs, not only in this region but also in areas with similar rearing practices.

Abstract
Hepatitis E virus (HEV) is the leading cause of acute viral hepatitis globally, with zoonotic potential, and pigs are considered the major reservoir. To determine the seroprevalence of HEV infection in pigs reared in backyard conditions in the northeastern region of India, blood samples were collected from 400 pigs from five northeastern states (80 samples from each state) and tested for IgG antibodies against HEV using an ELISA assay. Questionnaires on farm characteristics and management practices were completed, and risk factors associated with HEV were studied using univariate and multivariate analysis. The apparent seroprevalence of HEV infection was 51% (46.1-55.9, 95% CI), with a true prevalence of 52.98% (47.22-58.75, 95% CI). The risk factors significantly associated with higher HEV seropositivity were as follows: lack of disinfection (OR 4.65), feeding swill (restaurant and bakery waste) (OR 2.55), failure to follow the all-in-all-out production system (OR 3.47), and medium holding size (OR 9.83), which refers to mixed rearing of younger and older age groups. This study demonstrates that HEV is widespread among pigs reared in northeastern India. The risk factor analysis conducted in this study provides valuable insights into the prevalence of HEV in the region.

Abstract
Staphylococcus aureus is an important and leading cause of foodborne diseases worldwide. Prompt detection and recall of contaminated foods are crucial to prevent untoward health consequences caused by S. aureus. Helix loop-mediated isothermal amplification (HAMP) is an exciting recent addition to the array of available isothermal-based nucleic acid amplification techniques. This study aimed to develop and evaluate a HAMP assay for detecting S. aureus in milk and milk products. The assay is completed in 75 minutes of isothermal temperature incubation (64 ˚C) and dye-based visual interpretation of results based on colour change. The specificity of the developed assay was ascertained using 27 S. aureus and 17 non S. aureus bacterial strains. The analytical sensitivity of the developed HAMP assay was 9.7 fg/µL of pure S. aureus DNA. The detection limit of the HAMP assay in milk (86 CFU/mL) was 1000x greater than the routinely used endpoint PCR (86 × 103 CFU/mL). The practicality of applying the HAMP assay was also assessed by analysing milk and milk product samples (n = 95) obtained from different dairy farms and retail outlets. The developed test is a more rapid, sensitive, and user-friendly method for the high-throughput screening of S. aureus in food samples and may therefore be suitable for field laboratories. To our knowledge, this is the first study to develop and evaluate the HAMP platform for detecting S. aureus.

Abstract
This study aimed to investigate the prevalence of Shiga toxin-producing Escherichia coli (STEC), Enteropathogenic E. coli (EPEC), and Enterotoxigenic E. coli (ETEC) in common food animals (cattle, goats, and pigs) reared by tribal communities and smallholder farmers in Northeast India. The isolates were characterized for the presence of virulence genes, extended-spectrum beta-lactamases (ESBL) production, antimicrobial resistance, and biofilm production, and the results were statistically interpreted. In pathotyping 141 E. coli isolates, 10 (7.09%, 95% CI: 3.45%-12.66%) were identified as STEC, 2 (1.42%, 95% CI: 0.17%-5.03%) as atypical-EPEC, and 1 (0.71%, 95% CI: 0.02%-3.89%) as typical-EPEC. None of the isolates were classified as ETEC. Additionally, using the phenotypic combination disc method (ceftazidime with and without clavulanic acid), six isolates (46.1%, 95% CI: 19.22%-74.87%) were determined to be ESBL producers. Among the STEC/EPEC strains, eleven (84.6%, 95% CI: 54.55%-98.08%) and one (7.7%, 95% CI: 0.19%-36.03%) strains were capable of producing strong or moderate biofilms, respectively. PFGE analysis revealed indistinguishable patterns for certain isolates, suggesting clonal relationships. These findings highlight the potential role of food animals reared by tribal communities and smallholder farmers as reservoirs of virulent biofilm-forming E. coli pathotypes, with implications for food contamination and zoonotic infections. Therefore, monitoring these pathogens in food animals is crucial for optimizing public health through one health strategy.

Abstract
The Corona Virus was first started in the Wuhan city, China in December of 2019. It belongs to the Coronaviridae family, which can infect both animals and humans. The diagnosis of coronavirus disease-2019 (COVID-19) is typically detected by Serology, Genetic Real-Time reverse transcription-Polymerase Chain Reaction (RT-PCR), and Antigen testing. These testing methods have limitations like limited sensitivity, high cost, and long turn-around time. It is necessary to develop an automatic detection system for COVID-19 prediction. Chest X-ray is a lower-cost process in comparison to chest Computed tomography (CT). Deep learning is the best fruitful technique of machine learning, which provides useful investigation for learning and screening a large amount of chest X-ray images with COVID-19 and normal. There are many deep learning methods for prediction, but these methods have a few limitations like overfitting, misclassification, and false predictions for poor-quality chest X-rays. In order to overcome these limitations, the novel hybrid model called "Inception V3 with VGG16 (Visual Geometry Group)" is proposed for the prediction of COVID-19 using chest X-rays. It is a combination of two deep learning models, Inception V3 and VGG16 (IV3-VGG). To build the hybrid model, collected 243 images from the COVID-19 Radiography Database. Out of 243 X-rays, 121 are COVID-19 positive and 122 are normal images. The hybrid model is divided into two modules namely pre-processing and the IV3-VGG. In the dataset, some of the images with different sizes and different color intensities are identified and pre-processed. The second module i.e., IV3-VGG consists of four blocks. The first block is considered for VGG-16 and blocks 2 and 3 are considered for Inception V3 networks and final block 4 consists of four layers namely Avg pooling, dropout, fully connected, and Softmax layers. The experimental results show that the IV3-VGG model achieves the highest accuracy of 98% compared to the existing five prominent deep learning models such as Inception V3, VGG16, ResNet50, DenseNet121, and MobileNet.

Abstract
Gram pod borer, Helicoverpa armigera (Hub.) is the major insect pest of pigeonpea and prediction of number of generations (no. of gen.) and generation time (gen. time) using growing degree days (GDD) approach during three future climate change periods viz., Near (NP), Distant (DP) and Far Distant (FDP) periods at eleven major pigeonpea growing locations of India was attempted. Multi-model ensemble of Maximum (Tmax) and Minimum (Tmin) temperature data of four Representative Concentration Pathways viz., RCP 2.6, 4.5, 6.0 and 8.5 of Coupled Model Inter comparison Project 5 (CMIP5) models was adopted here. The increase in projected Tmax and Tmin are significant during 3 climate change periods (CCPs) viz., the NP, DP and FDP over base line (BL) period under four RCP scenarios at all locations and would be higher (4.7-5.1 °C) in RCP 8.5 and in FDP. More number of annual (10-17) and seasonal (5-8) gens. are expected to occur with greater percent increase in FDP (8 to 38%) over base line followed by DP (7 to 22%) and NP (5to 10%) periods with shortened annual gen. time (4 to 27%) across 4 RCPs. The reduction of crop duration was substantial in short, medium and long duration pigeonpeas at all locations across 4 RCPs and 3 CCPs. The seasonal no.of gen. is expected to increase (5 to 35%) with shortened gen. time (4 to 26%) even with reduced crop duration across DP and FDP climate periods of 6.0 and 8.5 RCPs in LD pigeonpea. More no. of gen. of H. armigera with reduced gen. time are expected to occur at Ludhiana, Coimbatore, Mohanpur, Warangal and Akola locations over BL period in 4 RCPs when normal duration of pigeonpeas is considered. Geographical location (66 to 72%), climate period (11 to 19%), RCPs (5-7%) and their interaction (0.04-1%) is vital and together explained more than 90% of the total variation in future pest scenario. The findings indicate that the incidence of H. armigera would be higher on pigeonpea during ensuing CCPs in India under global warming context.

Abstract
Brucellosis is an economically important livestock disease worldwide besides having a noteworthy impact on human health. In this study, a rapid, simple, and ultra-sensitive nuclei-acid diagnostic technique was developed for the detection of brucellosis harnessing saltatory rolling circle amplification (SRCA). The diagnostic method was developed using World Organization for Animal Health (WOAH) approved primers targeting the bcsp31 gene of the Brucella genome. The assay can be accomplished within 90 min at a temperature of 65 °C without the requirement of sophisticated instrumentation. The result interpretation can be done with the naked eye with the aid of SYBR green dye. The developed technique displayed 100% specificity by amplifying only 10 reference and field strains of Brucella spp. and there was no cross-reactivity with the other tested pathogens. The lower limit of detections of SRCA and end-point PCR assays were 9.7 fg/μL (2.7 genome copies of Brucella) and 970 fg/μL, respectively. Thus, the developed SRCA assay was found to be 100× more sensitive than the end-point PCR assay. To the best of our knowledge, our study is the first one to develop an SRCA-based assay for the detection of brucellosis and it can be a diagnostic tool for resource-constrained laboratories and veterinary hospitals.

Abstract
Tympanoplasty is a surgical procedure which includes eradication of disease from the middle ear and reconstruction of the hearing mechanism with or without tympanic membrane repair. The purpose of this article was to compare the clinical and audiological outcomes of Type 1 underlay tympanoplasty with or without anterior tucking of the temporals fascia graft. This is a prospective interventional study which included 100 patients between 15 and 60 years of age, diagnosed with chronic otitis media, mucosal disease inactive stage. 100 patients were divided into two groups 50 each, who underwent type 1 underlay tympanoplasty, group A underwent anterior tucking of the temporals fascia graft and group B without anterior tucking of the temporals fascia graft. Analysis of data was made of the demographic details, graft uptake status and audiological outcomes following surgery. Among the 100 patients included in the study, majority were seen between 21 and 40 years of age group. In our study successful graft uptake was seen in 93.4% in group A temporalis fascia with anterior tucking which was better than group B which showed 84% results. However hearing outcome was almost similar in both the groups. In conclusion, graft uptake in tympanoplasty with anterior tucking was found to be better than without anterior tucking. There is significant hearing improvement following underlay technique of tympanoplasty both with and without anterior tucking. There is no significant difference in the hearing improvement with anterior tucking when compared to without anterior tucking of the temporalis fascia graft.

Abstract
BACKGROUND India today is home for the largest youth population in the world. Youth is a formative phase transitioning from childhood to adulthood. Relationship is fundamental for a healthy and satisfactory life. Relationships assume importance and maturity during adolescence and youth. Relationships and mental health have a bidirectional effect. The effect of relationships on mental health is stronger than vice versa. MATERIALS AND METHODS Two-year case record analysis of 8595 beneficiaries aged 15-35 years attending youth guidance centers (Yuva Spandana Kendras) in Karnataka, India, was undertaken to understand factors affecting relationship issues among them. Multivariate logistic regression was performed with any beneficiary having a relationship issue as outcome. RESULTS Being a student (adjusted odds ratio [AOR] = 1.49; 95% confidence interval [CI] = 1.18-1.89), occupation (AORbusiness/salaried = 3.04; 95% CI = 2.10-4.40 and AORothers = 1.72; 95% CI = 1.22-2.44), marital status (AORmarried = 1.42; 95% CI = 1.06-1.90 and AORothers = 3.44; 95% CI = 1.45-8.15), having health and lifestyle issues (AOR = 3.61; 95% CI = 3.05-4.27), personality issues (AOR = 2.88; 95% CI = 2.43-3.41), safety issues (AOR = 6.28; 95% CI = 5.01-7.87), gender, sex, and sexuality issues (AOR = 3.10; 95% CI = 1.93-4.98), suicidality (AOR = 1.82; 95% CI = 1.17-2.85), alcohol use (AOR = 5.43; 95% CI = 3.92-7.41), and different emotions experienced (AOR ranging from 0.37 to 3.50), had significant association with relationship issues. CONCLUSION Investing in health promotion interventions focusing on these precursors of relationship issues among youth seems strategic. Our findings have implications for other states in India and other low-middle-income countries like India.

Abstract
Screening of chemicals related to chemical weapons convention including their all possible degradation and reaction products in environmental samples is important in the organization for prohibition of chemical weapons verification process. Sulfur mustards, commonly known as blistering agents, are included in schedule 1 chemicals of chemical weapons convention. Because of the presence of chlorine atoms in sulfur mustards, they are highly reactive and prone to react with other organic molecules such as phenols to produce corresponding reaction products. Thus, it is important to screen for not only the sulfur mustards but also their reaction products for verification process. The sulfur mustards and their degradation products have been routinely analyzed by gas chromatography/mass spectrometry method, however, the methods are yet to establish for the reaction products. In this study, the reaction products of the sulfur mustards with phenol (compounds 1-7) were studied by gas chromatography/mass spectrometry under electron ionization and chemical ionization conditions. The EI spectra of 1-7 displayed molecular ion and characteristic fragments that provided structure information. Mostly the fragment ions were due to homolytic cleavages involving C-O, C-S, and C-C cleavages. The methane or isobutane CI spectra showed M+., [M + H]+, and [M - H]+ ions including reagent specific adduct ions. The CI spectra also showed other adduct ions formed by association of analyte molecule with its most abundant fragment ion. The gas chromatography/retention index values were also calculated, which support unambiguous identification of targeted molecules in suspected environmental samples. The method was demonstrated for detection of the targeted molecules spiked in soil samples.

Abstract
Brucellosis is an important zoonosis worldwide. In livestock, it frequently causes chronic disease with reproductive failures that contribute to production losses, and in humans, it causes an often-chronic febrile illness that is frequently underdiagnosed in many low- and middle-income countries, including India. India has one of the largest ruminant populations in the world, and brucellosis is endemic in the country in both humans and animals. In November 2017, the International Livestock Research Institute invited experts from government, national research institutes, universities, and different international organizations to a one-day meeting to set priorities towards a "One Health" control strategy for brucellosis in India. Using a risk prioritization exercise followed by discussions, the meeting agreed on the following priorities: collaboration (transboundary and transdisciplinary); collection of more epidemiological evidence in humans, cattle, and in small ruminants (which have been neglected in past research); Economic impact studies, including cost effectiveness of control programmes; livestock vaccination, including national facilities for securing vaccines for the cattle population; management of infected animals (with the ban on bovine slaughter, alternatives such as sanctuaries must be explored); laboratory capacities and diagnostics (quality must be assured and better rapid tests developed); and increased awareness, making farmers, health workers, and the general public more aware of risks of brucellosis and zoonoses in general. Overall, the meeting participants agreed that brucellosis control will be challenging in India, but with collaboration to address the priority areas listed here, it could be possible.

Abstract
AIMS To estimate the serum fucose levels in clinically and histopathologically diagnosed oral cancer, oral leukoplakia, and oral submucous fibrosis cases. To compare and correlate the severity of dysplasia or histopathological grading of the premalignant and malignant lesions with serum fucose levels. OBJECTIVE To determine the role of serum fucose as a reliable biomarker for early detection of malignant transformation of potentially malignant lesions and conditions and prediction of biologic behavior of the malignant lesions. MATERIAL AND METHOD The intended study shall include 100 participants divided into 4 groups. Groups I, II, and III will include 25 clinically and histological diagnosed cases of oral leukoplakia, oral submucous fibrosis, and oral cancer, and 25 normal control group. Fucose was measured according to the method of Dische and Shettles as adopted by Winzler. STATISTICAL ANALYSIS Statistical analysis will be done using SPSS statistical software (Version 10), and the levels of significance will be analyzed using the paired and unpaired t-tests. RESULT In subjects of 4 groups were age- and gender-matched and comparable thus these may also not influence the study outcome measure (fucose levels). ANOVA revealed significantly different fucose levels among the groups (F = 17.00, P < 0.001). Mean fucose level did not differ (P > 0.05) between oral leukoplakia, oral submucous fibrosis, and oral cancer (84.5%) groups. The increase in mean fucose levels with severity was the highest in the oral cancer group followed by oral submucous fibrosis and oral leukoplakia group. The mean fucose levels did not differ between mild and moderate grades (P > 0.05) in all the 3 groups. CONCLUSION The evaluation of serum l-fucose would be of good help in assessing early malignant change in increasing the accuracy of clinical diagnosis and also in assessing the spread and invasiveness of oral cancer, oral submucous fibrosis, and leukoplakia.

Abstract
Developing cultivars with traits that can enhance and sustain productivity under climate change will be an important climate smart adaptation option. The modified CSM-CERES-Pearl millet model was used to assess yield gains by modifying plant traits determining crop maturity duration, potential yield and tolerance to drought and heat in pearl millet cultivars grown at six locations in arid (Hisar, Jodhpur, Bikaner) and semi-arid (Jaipur, Aurangabad and Bijapur) tropical India and two locations in semi-arid tropical West Africa (Sadore in Niamey and Cinzana in Mali). In all the study locations the yields decreased when crop maturity duration was decreased by 10% both in current and future climate conditions; however, 10% increase in crop maturity significantly (p<0.05) increased yields at Aurangabad and Bijapur, but not at other locations. Increasing yield potential traits by 10% increased yields under both the climate situations in India and West Africa. Drought tolerance imparted the lowest yield gain at Aurangabad (6%), the highest at Sadore (30%) and intermediate at the other locations under current climate. Under climate change the contribution of drought tolerance to the yield of cultivars either increased or decreased depending upon changes in rainfall of the locations. Yield benefits of heat tolerance substantially increased under climate change at most locations, having the greatest effects at Bikaner (17%) in India and Sadore (13%) in West Africa. Aurangabad and Bijapur locations had no yield advantage from heat tolerance due to their low temperature regimes. Thus drought and heat tolerance in pearl millet increased yields under climate change in both the arid and semi-arid tropical climates with greater benefit in relatively hotter environments. This study will assists the plant breeders in evaluating new promising plant traits of pearl millet for adapting to climate change at the selected locations and other similar environments.

Abstract
Tamil Nadu is located in the South-Eastern part of Indian peninsula, between 8.087° and 13.09°N and 76.50° and 80.27°E. Bluetongue (BT) was first reported in this region in sheep during 1982 with regular occurrence thereafter. In 1989-1990, 1997-1998 and 2005-2006, there was wide spread occurrence of BT resulting in huge mortality of sheep. The present study had the goal of isolating the BTV from outbreaks in sheep occurred in Tamil Naadu between 2003-2011 and comparing the VP2 gene sequences of the BTV isolates involved in such outbreaks. Serotypes 1, 2, 16, and 23 of the Bluetongue virus (BTV) have been isolated from sheep during BT outbreaks. BTV-16 has also been isolated in goats and cattle in the region; BTV-2 isolated in Tamil Nadu has homology with BTV-2 isolated in Africa; whereas the BTV-23 isolated in this area has homology with BTV-23 from South East Asia, indicating that both Eastern and Western topotypes of BTV are circulating in ruminant population in Tamil Nadu.

Abstract
The aim of this study was to report the success of maintaining reduced distal radius fractures with cast immobilisation and analyse risk factors for redisplacement. A retrospective analysis of distal radius fracture manipulated between April 2011 and 2013 was conducted. Age, gender, fracture classification, ulna fracture, dorsal comminution and volar alignment were recorded. Reduction and redisplacement were measured using Sarmiento's modification of Lidstrom's system. 110 patients were included ; mean age 62.8 years and 83.4% female. The AO classification was used to grade initial fractures A2 (44%), A3 (25%), C1 (20%) and C2 (10%). 86.4% of cases were improved following manipulation, although 48.4% redisplaced and 27.4% required surgical intervention. The radial length (60%) was harder to maintain than dorsal alignment (44%) in cases of redisplacement. Successful alignment of the volar cortices was associated with a statistically significant reduction in redisplacement (p = 0.024). Manipulation of distal -radius fractures is initially beneficial but half of cases redisplace.

Abstract
Background & objectives: Improving quality of life (QOL) of healthy people living with HIV (PLHIV) is critical needing home-based, long-term strategy. Sudarshan Kriya yoga (SKY) intervention is acknowledged for its positive impact on health. It is hypothesised that SKY would improve PLHIV's QOL, justifying an evaluation. Methods: In this open label randomized controlled pilot trial, 61 adult PLHIV with CD4 count more than 400 cells/µl and Karnofsky scale score above 70 were enrolled. Those with cardiac disease, jaundice, tuberculosis, or on antiretroviral therapy/yoga intervention were excluded. All were given standard care, randomized to SKY intervention (31: I-SKY) and only standard of care in control (30: O-SOC) arms. The I-SKY participants were trained for six days to prepare for daily practice of SKY at home for 30 min. A validated 31-item WHOQOL-HIVBREF questionnaire was used to document effect in both arms from baseline to three visits at 4 wk interval. Results: Baseline QOL scores, hypertension and CD4 count were similar in both arms. An overall 6 per cent improvement of QOL scores was observed in I-SKY group as compared to O-SOC group, after controlling for baseline variables like age, gender, education and occupation (P =0.016); 12 per cent for physical (P =0.004), 11 per cent psychological (P =0.023) and 9 per cent level of independence (P =0.001) domains. Improvement in I-SKY observed at post-training and in the SKY adherence group showed increase in these two domains. Conclusions: A significant improvement in QOL scores was observed for the three health related QOL domains in SKY intervention arm. This low cost strategy improved physical and psychological state of PLHIV calling for upscaling with effective monitoring for sustainability of quality of life.

Abstract
BACKGROUND Fixed appliances hinder the effective control of plaque accumulation and white spot lesions may develop under the ill fitting bands or adjacent to the stainless steel brackets during orthodontic treatment particularly the etching process. AIMS AND OBJECTIVES Comparative study of tensile bond strength of an orthodontic adhesive with and without fluoride application after acid etching to know the effect of fluoride on bond strength. MATERIALS AND METHODS This study is carried out on 90 non carious human premolar teeth, and divided in 6 groups with each group of 15 specimens. In those Groups I and IV were control group acid etch treatment, Group II and V is 1.23% APF gel (acid etch plus APF gel treatment,) and group III and VI is 8% SnF2 (acid etch plus SnF2 treatment). Samples of Group I, II and III bond strength were tested after 24 h and groups IV, V and VI after one month on microtechtensometer machine. The scanning electron microscope (SEM) investigation was carried out for the 2 specimens for the control group after acid etch and 4 specimens after acid etch with fluoride application for fluoride groups. RESULTS Control and SnF2 treated groups was found to be nearly similar to the control group whereas APF treated group showed less focal holes than the other 2 groups. CONCLUSION Fluoride application after acid etching without having an adverse effect on bond strength but we can prevent the white spot lesions and caries.

Abstract
OBJECTIVE The aim of this study is to establish the sensitivity and specificity of MRA in the investigation of patients with traumatic anterior shoulder dislocations. MATERIALS AND METHODS A retrospective analysis of consecutive patients undergoing both magnetic resonance arthrography and arthroscopic assessment after a traumatic anterior shoulder dislocation between January 2011 and 2014 was performed. Demographic data were collected from electronic records. Images were interpreted by 8 musculoskeletal radiologists and patients were treated by 8 consultant orthopaedic surgeons. Arthroscopic findings were obtained from surgical notes and these findings were used as a reference for MRA. The sensitivity, specificity, and positive predictive value were calculated for the different injuries. RESULTS Sixty-nine patients underwent both an MRA and shoulder arthroscopy during the study period; however, clinical notes were unavailable in 9 patients. Fifty-three patients (88 %) were male, the mean age was 28 years (range 18 to 50) and 16 subjects (27 %) had suffered a primary dislocation. The overall sensitivity and specificity of MRA to all associated injuries was 0.9 (CI 0.83-0.95) and 0.94 (CI 0.9-0.96) retrospectively. The lowest sensitivity was seen in osseous Bankart 0.8 (CI 0.44-0.96) and superior labral tear (SLAP) lesions 0.5 (CI 0.14-0.86). The overall positive predictive value was 0.88 (CI 0.76-0.91) with the lowest values found in rotator cuff 0.4 (CI 0.07-0.83) and glenohumeral ligament (GHL) lesions 0.29 (CI 0.05-0.7). CONCLUSION Magnetic resonance angiography has a high sensitivity when used to identify associated injuries in shoulder dislocation, although in 8 patients (13 %) arthroscopy identified an additional injury. The overall agreement between MRA and arthroscopic findings was good, but the identification of GHL and rotator cuff injuries was poor.

Abstract
INTRODUCTION Oral Submucous Fibrosis (OSMF) is precancerous condition caused by areca nut chewing characterized by restricted mouth opening, burning sensation and stiffness & blanching of oral mucosa. Complete regression of the condition had not been achieved in all cases with any of the present treatment regimens. Curcumin is (diferuloylmethane), a yellow pigment in curry powder, exhibits anti-oxidant, anti-inflammatory, and pro-apoptotic activities. Hence an interventional study was undertaken to establish the efficacy of curcumin in OSMF patients. SETTINGS & DESIGN A randomized open label, interventional study was conducted in forty patients with clinically and histologically proven Oral Submucous Fibrosis. MATERIALS & METHODS Forty patients with clinically and histologically proven Oral Submucous Fibrosis were selected for the study and were randomly divided into 2 groups. The first group was treated with weekly intralesional injection of 4 mg Dexamethasone & 1500 I.U Hyaluronidase and the second group by oral administration of two Curcumin tablets (Turmix 300 mg) per day for 3 months each. Improvement of burning sensation, interincisal distance and tongue protrusion was evaluated on a weekly basis. RESULTS Burning sensation improved in both the groups from early to late stages. Complete resolution of burning sensation was noted with turmix. The mean increase in interincisal distance was 3.13 mm and 1.25 mm respectively in groups 1 &2. The interincisal distance improved in both the groups, with significant results at the end of first month. Tongue protrusion showed greater recovery at the end of 1st month in group 1 when compared with group 2. CONCLUSION Turmix is beneficial and effective in reducing burning sensation in early OSMF patients.

Abstract
AIM The purpose of this cross sectional study was to understand and evaluate local practioner's knowledge on dental bur selection, its usage, sterilization procedures undertaken and the method of disposal of dental burs in restorative procedures. MATERIALS AND METHODS A Questionnaire proforma was prepared with each question having 4 answers. A total of 20 questions were framed and were sub-divided in to 3 categories namely selection, usage sterilization and disposal. These Questionnaire were sent to all the local practioner's by mail and to ensure a high response rate as they were followed up by telephone calls. The results were analyzed statistically and were represented in the form of percentage. RESULTS A total 131 out of 150 practioner's answered the questions, a response rate of 87%. Most of the practioner's preferred diamonds (75%) over tungsten carbide (15%) burs. most of the dentists used burs till they were worn out (85%) and many of the dentists agreed that the cutting efficiency of bur decreased with usage (33%). Clinicians usually sterilized burs either once daily (35%) or for every patient (35%). Almost every practioner discarded their worn out burs into dustbin (100%). CONCLUSION From the survey we came to know the operators attitude towards one group of burs in terms of cutting efficiency. In terms of cutting efficiency diamond burs predominated the choice irrespective of the grit size. Burs were used repeatedly till they were worn out and minimal coolant was used during tooth preparation and believed that it didn't have any effect on the cutting efficiency.

Abstract
Alzheimer's disease (AD) is the most common form of dementia. It is the sixth leading cause of death in old age people. Despite recent advances in the field of drug design, the medical treatment for the disease is purely symptomatic and hardly effective. Thus there is a need to understand the molecular mechanism behind the disease in order to improve the drug aspects of the disease. We provided two contributions in the field of proteomics in drug design. First, we have constructed a protein-protein interaction network for Alzheimer's disease reviewed proteins with 1412 interactions predicted among 969 proteins. Second, the disease proteins were given confidence scores to prioritize and then analyzed for their homology nature with respect to paralogs and homologs. The homology persisted with the mouse giving a basis for drug design phase. The method will create a new drug design technique in the field of bioinformatics by linking drug design process with protein-protein interactions via signal pathways. This method can be improvised for other diseases in future.

Abstract
Residual ridge resorption has been considered as an inevitable consequence after extraction of the teeth. There is a gradual loss of the alveolar bone due to the pattern of bone remodeling. In spite of the availability of newer treatment modalities like endodontic restoration and periodontic procedures for preservation of the remaining teeth they are not feasible for the patients in severe stages where restoration might not be possible. The only reliable method of preserving the remaining bone is by maintaining the functional health of the teeth. Over the years, many studies showed that roots which are fractured and left behind during extractions are retained into the alveolar bone with no evidence of pathosis. Over denture as a treatment option was developed in an effort to preserve the remaining alveolar bone by retaining the natural teeth or roots. In over denture treatment, the teeth selected as abutments are prone to caries and periodontal disease over a period of time, hence evolved the vital or non vital root submergence concept. After a thorough radiographic and clinical examination, few teeth without pathosis are retained that eventually are surgically submerged in the alveolar ridge. After healing, the over denture with reaining vital or non vital teeth preserve the integrity of the bone, making the treatment an effective and successfull preventive prosthodontic treatment.

Abstract
The growth, development and consumption of four successive generations of semilooper, Achaea janato reared on castor (Ricinus communis L.) foliage grown under elevated carbon dioxide (550 and 700 parts per million ) concentrations in open top chambers were estimated at Hyderabad, India. Significantly lower leaf nitrogen, higher carbon, higher relative proportion of carbon to nitrogen (C: N) and higher polyphenols expressed in terms of tannic acid equivalents were observed in castor foliage under elevated CO2 levels. Significant influence on life history parameters of A. jonata viz., longer larval duration, increased larval survival rates and differential pupal weights in successive four generations were observed under elevated over ambient CO2 levels. The consumption per larva under elevated CO2 increased from first to fourth generation. An increase in approximate digestibility and relative consumption rate, decreased efficiency of conversion of ingested food and digested food and relative growth rate of the four generations under elevated CO2 levels was noticed. Potential population increase index was lower for successive generations under both elevated CO, over ambient. The present findings indicated that elevated CO2 levels significantly alter the quality of castor foliage resulting in higher consumption and better assimilation by larvae, slower growth and longer time to pupation besides producing less fecund adults over generations.

Abstract
Oral lichen planus (OLP) is a chronic mucocutaneous disease of uncertain etiopathogenesis. Several factors including stress, genetics, systemic diseases, viruses, dental restorative materials and drugs have been implicated as causative agents. The disease seems to be mediated by an antigen specific mechanism, activating cytotoxic T cells, and non specific mechanisms like mast cell degranulation and matrix metalloproteinase activation. Further clarity on the pathogenesis will aid in modifying therapeutic interventions, thus significantly reducing the morbidity of OLP patients.

Abstract
The electrospray ionization collisionally activated dissociation (CAD) mass spectra of protonated 2,4,6-tris(benzylamino)-1,3,5-triazine (1) and 2,4,6-tris(benzyloxy)-1,3,5-triazine (6) show abundant product ion of m/z 181 (C(14) H(13)(+)). The likely structure for C(14) H(13)(+) is α-[2-methylphenyl]benzyl cation, indicating that one of the benzyl groups must migrate to another prior to dissociation of the protonated molecule. The collision energy is high for the 'N' analog (1) but low for the 'O' analog (6) indicating that the fragmentation processes of 1 requires high energy. The other major fragmentations are [M + H-toluene](+) and [M + H-benzene](+) for compounds 1 and 6, respectively. The protonated 2,4,6-tris(4-methylbenzylamino)-1,3,5-triazine (4) exhibits competitive eliminations of p-xylene and 3,6-dimethylenecyclohexa-1,4-diene. Moreover, protonated 2,4,6-tris(1-phenylethylamino)-1,3,5-triazine (5) dissociates via three successive losses of styrene. Density functional theory (DFT) calculations indicate that an ion/neutral complex (INC) between benzyl cation and the rest of the molecule is unstable, but the protonated molecules of 1 and 6 rearrange to an intermediate by the migration of a benzyl group to the ring 'N'. Subsequent shift of a second benzyl group generates an INC for the protonated molecule of 1 and its product ions can be explained from this intermediate. The shift of a second benzyl group to the ring carbon of the first benzyl group followed by an H-shift from ring carbon to 'O' generates the key intermediate for the formation of the ion of m/z 181 from the protonated molecule of 6. The proposed mechanisms are supported by high resolution mass spectrometry data, deuterium-labeling and CAD experiments combined with DFT calculations.

Abstract
An area of 0.6 km(2) in the manganese nodule field of the Central Indian Basin was physically disturbed and sediments discharged in the near bottom waters to simulate seabed mining and study its impact on benthic ecosystem. An estimated 2 to 3 tonnes of sedimentary organic carbon (C(org)) was resuspended into the water column during a 9-day experiment. The majority of the sediment cores from within the disturbed area and areas towards the south showed a ~30% increase in C(org) content as well as an increase in carbon burial rates after disturbance, though with a reduction in carbon/phosphorus ratios. High specific surface area (SSA~25 m(2) g(-1)) and low C(org)/SSA ratios (mostly <0.5) are typical of deep-sea sediments. The increased C(org) values were probably due to the organic matter from dead biota and the migration and redeposition of fine-grained, organic-rich particles. Spatial distribution patterns of C(org) contents of cores taken before and after disturbance were used to infer the direction of plume migration and re-sedimentation. A positive relationship was observed between total and labile C(org) and macrobenthos density and total bacterial numbers prior to disturbance, whereas a negative relationship was seen after disturbance owing to drastic reduction in the density of macrofauna and bacteria. Overall decrease in labile organic matter, benthic biota and redistribution of organic matter suggest that the commercial mining of manganese nodules may have a significant immediate negative effect on the benthic ecosystem inducing changes in benthic community structure.
