Abstract
The present study was undertaken to identify polymorphism in the coding sequence of GDF8gene across indigenous meat type sheep breeds. A 1647 bp sequence was generated, encompassing 208 bp of the 5'UTR, 1128 bp of coding region (exon1, 2 and 3) as well as 311 bp of 3'UTR. The sheep and goat GDF8 gene sequences were observed to be highly conserved as compared to cattle, buffalo, horse and pig. Several nucleotide variations were observed across coding sequence of GDF8 gene in Indian sheep. Three polymorphic sites were identified in the 5'UTR, one in exon 1 and one in the exon 2 regions. Both SNPs in the exonic region were found to be non-synonymous. The mutations c.539T > G and c.821T > A discovered in this study in the exon 1 and exon 2, respectively, have not been previously reported. The information generated provides preliminary indication of the functional diversity present in Indian sheep at the coding region of GDF8gene. The novel as well as the previously reported SNPs discovered in the Indian sheep warrant further analysis to see whether they affect the phenotype. Future studies will need to establish the affect of reported SNPs in the expression of the GDF8 gene in Indian sheep population.

Abstract
BACKGROUND The future health of individuals depends on the well being of the children of today. Proper nutrition for children is very important. The most commonly used index of obesity and over weight is Body Mass Index. The growth of children should be monitored using the Body Mass Index (BMI) and risk factors assessed through a dietary and physical activity history. The increase in obesity is attributed to increased carbohydrate consumption among children. Obesity and caries are both diet-based conditions that share a cause that is, excessive ingestion of fermentable carbohydrates. OBJECTIVE This study was undertaken to determine the association of nutritional status with dental caries in 8 to 12 year old children of Udaipur city. METHOD The present study was conducted on a random sample of 1000 boys and girls, aged 8-12 years. The children were selected from schools located in the Udaipur City, Rajasthan. The schools examined were of government and private sector schools in Udaipur city. The children from schools of Udaipur city was taken in the study with male, female and age group ratio as per distribution in population. A proforma was used to record children's age, gender, school, year, height, weight, parental income and dental caries status. Statistical analysis was done using Statistical Package of Social Science (SPSS Version 15; Chicago Inc., USA). RESULT It was found that caries free individuals were more from normal nutritional status group with 134 (13.4 %) subjects where as only 11 (1.1 %) of subjects obese children were found caries free. CONCLUSION Study shows that the children with normal BMI for age had more caries in their primary teeth, as well as in their permanent teeth, than the overweight children.

Abstract
OBJECTIVE To assess the safety and immunogenicity of a quadrivalent meningococcal (groups A,C,Y,W) polysaccharide diphtheria toxoid conjugate vaccine (MenACYW-DT) in India. DESIGN Open-label, descriptive, non-randomized study. SETTING Three medical college hospitals, one each in New Delhi, Bengaluru and Mumbai, India. PARTICIPANTS 300 healthy, vaccine-naïve participants (100 children aged 2-11 years, 100 adolescents aged 12-17 years, and 100 adults aged 18-55 years). INTERVENTION One dose (0.5 mL) of MenACYW-DT administered intramuscularly. MAIN OUTCOME MEASURES Serum bactericidal antibody titers against A, C, Y, and W were measured before and after MenACWY-DT vaccination. Safety data were also collected. RESULTS Thirty days post-vaccination, geometric mean titers rose across all serogroups. Most participants had protective titers >8 (1/dil) across the four serogroups. The percentage (95% CI) achieving >8 (1/dil) in the Adolescent Group was typical - A: 96.9% (91.2%; 99.4%); C: 96.9% (91.2%; 99.4%); Y:100% (96.3%; 100%); W:100% (96.3%; 100%). In general, solicited reactions were mild and short-lived. Unsolicited events were uncommon and unrelated to vaccination. CONCLUSIONS MenACYW-DT was well tolerated and elicited a robust and protective immune response 30 days post-vaccination against meningococcal serogroups A, C, Y, and W-135 in the Indian study participants aged 2-55 years.

Abstract
BACKGROUND Rheumatoid arthritis (RA), a chronic and systemic inflammation, results in destruction of joints and cartilages. Effectiveness of curcumin has been established in a wide variety of inflammatory disorders, but its utility as a therapeutic agent is limited by its poor absorption, rapid metabolism and fast systemic elimination. To apprehend these limitations, we propose to use highly bioavailable curcumin loaded solid lipid nanoparticles (C-SLNs) for the treatment of RA. METHODS In the present study, the protective effect of curcumin and its SLNs was evaluated in complete Freund's adjuvant (CFA)-induced arthritis in rats. RESULTS Arthritic rats exhibited marked decrease in paw withdrawal threshold in Randall-Selitto and von Frey hair test along with decreased reaction time in hot plate. Arthritic rats also showed significant joint hyperalgesia, joint stiffness and increased paw volume along with marked decrease in mobility score. Arthritic rats showed a significant increase in blood leukocyte count, oxidative-nitrosative stress, tumour necrosis factor-α, C-reactive protein, cyclic citrullinated peptide antibody levels and radiological alterations in tibiotarsal joint. C-SLN administration (10 and 30 mg/kg), when compared with free curcumin (10 and 30 mg/kg), significantly and dose dependently ameliorated various symptoms of arthritis in rats, improved biochemical markers and preserved radiological alterations in joints of arthritic rats. CONCLUSIONS The current findings suggest the protective potential of curcumin-SLNs in ameliorating CFA-induced arthritis in rats through attenuation of oxido-inflammatory and immunomodulatory cascade. Further, the results emphasize that SLNs are a novel approach to deliver curcumin into the inflamed joints and improve its biopharmaceutical performance.

Abstract
INTRODUCTION The purpose of the current study was to investigate the effects of residual articular incongruity after Bennett's fracture on load distribution of the joint surface. Our aim was to investigate whether a residual joint step and the altered load distribution led to negative clinical outcomes or symptomatic degenerative osteoarthritis of the trapeziometacarpal joint. PATIENTS AND METHODS Twenty-four patients were available for long-term follow-up examination and were contacted by phone, and they returned for follow-up examination. Computed tomography (CT) scans of both carpometacarpal (CMC) joints were performed. CT scans were taken in the sagittal plane of the forearms with a slice thickness of 0.625 mm for three-dimensional reconstruction. The CMC joints were analysed due to a residual step in the joint. Only patients with a residual step-off were included in this study. To determine the areas of maximum density in the joint, CT-osteoabsorptiometry was performed. RESULTS Ten patients had the maximum loading area radial and two patients central. The second major position of mineralization was detected central in four patients, volar-ulnar in two patients, radial in one patient, dorso-radial in one patient, volar in one patient and volar-radial in two patients. CONCLUSION Finally, no higher loading in the area of the beak fragment could be found. The Wagner technique, even if it results in a persistent 1-2-mm intra-articular step-off of the beak fragment, is still the favourable method for the treatment of Bennett's luxation fractures.

Abstract
BACKGROUND Determination of correct working length is one of the keys to success in endodontic therapy. AIM The aim of this study was to evaluate the diagnostic efficacy of various methods to determine working length of root canal. MATERIALS AND METHODS Tactile method was assessed using digital radiography and compared with electronic method using apex locator. A total sample of 30 single rooted young permanent teeth the (mandibular first premolars) with matured apices were selected for the study. Access cavity preparation was carried out. Working length was measured by tactile method using digital radiography and electronic method using apex locator with no 15 K file. Actual working length was established by grinding of cementum and dentine from the root apex and was observed under stereomicroscope. Data was collected and statistical analysis was carried out with the help of SPSS-15. RESULTS The results of this study showed that there was a significant difference between tactile method assessed by digital radiography and electronic method using apex locator. CONCLUSION Apex locator was found to be more reliable and accurate when compared with the actual length.

Abstract
Purpose To compare intraocular pressure (IOP) measurements, taken using Perkins applanation tonometry (PAT) and Goldmann applanation tonometry (GAT). Methods 100 eyes of 100 patients underwent Perkins and Goldmann applanation tonometry, with a randomized order of modality, performed by a masked observer. The right eye was measured, for all subjects, and the data used in statistical analysis. The comparability of results given by the two instruments was evaluated using the Bland–Altman method. Results IOP measurements for 100 eyes were obtained (range: 10–44 mmHg). The mean GAT reading was 21.63 mmHg, with standard deviation (SD) 5.69 mmHg. The mean PAT reading was 21.40 mmHg, with SD 5.67 mmHg. The mean difference between readings from Goldmann versus Perkins tonometry was 0.22 mmHg (SD: 0.44 mmHg). The limits of agreement were calculated to be −0.64–+1.08 mmHg (1.96 SD either side of the bias). Conclusion The Perkins applanation tonometer yields IOP measurements that are closely comparable with GAT. Therefore, PAT may be used in routine clinical practice, as part of the implementation of national guidelines, or preferred practice patterns, for glaucoma and ocular hypertension.

Abstract
More than three decades have passed since the introduction of transcatheter devices for closure of patent ductus arteriosus, and many occluders have been made available since then. The ideal requirements of any procedure are a user-friendly technique, optimum success rate, no residual anomaly, minimal morbidity/mortality, and comparability or superiority to the existing conventional modality of treatment. With various advancements in device design, delivery and assisted systems, the tremendous procedural safety and effectiveness, along with low cost and widespread availability of these devices makes transcatheter closure of patent ductus arteriosus a preferred therapeutic modality in all age groups, with decreasing demographic trends of surgical management.

Abstract
Abstract
Purpose: Triple-negative breast cancer (TNBC), representing up to 20% of all breast cancer cases, is a highly diverse group of cancer that is associated with an aggressive phenotype, with affected patients having a poorer prognosis. Its treatment has been challenging due to its heterogeneity and the absence of well-defined molecular targets.
Epithelial-to-mesenchymal transition (EMT) is one of the hallmarks of aggressive breast cancers and is associated with increased metastatic potential. TNBCs have been shown to exhibit elevated EMT. Thus, reversal of EMT has been identified as a viable target in the treatment of aggressive breast cancers.
FOXM1 is an oncogenic transcription factor of the Forkhead family and it has a well-defined role in cell proliferation and cell-cycle progression. FOXM1 has been reported to be over-expressed in breast cancer. In prostate cancer, FOXM1 overexpression has been linked to increase EMT. We have previously shown that targeting NF-kB with panepoxydone (PP), an NF-kB inhibitor isolated from Lentinus crinitus (an edible mushroom), has significant antitumor activity against breast cancer cells with a resultant decrease in cell migration and invasion and induction of apoptosis. We have further identified that the FOXM1 promoter has a binding site for NF-kB. Thus, in this study, we investigated whether PP-induced inhibition of breast cancer cell growth could be attributed to FoxM1 activity and EMT reversal.
Experimental Design: The estrogen receptor positive (MCF-7) and three different triple negative (MDA-MB-231, MDA-MB-453, and MDA-MB-468) breast cancer cell lines were selected to observe the effect of PP on FOXM1and EMT markers.
Results: In the current study, we investigated whether panepoxydone- induced inhibition of breast cancer cell growth could be attributed to FoxM1activity and EMT reversal. Breast cancer cells were treated with increasing concentrations of PP and proteins collected after 24 hrs. Panepoxydone treatment significantly reduced FOXM1 expression in MCF-7 and MDA-MB-231 (1.7 and 2.4-fold, respectively, p < 0.05) but not in MDAMB-453 and MDAMB-468 cells when analyzed through western blot analysis. Furthermore, we showed that treatment with PP resulted in alteration of EMT-associated proteins with a significant increase in E-cadherin in all the cell lines (ranging from 1.8 to 4.2-fold, p < 0.05) and a decrease in mesenchymal markers vimentin and zeb1 in the MDA-MB-231 cells (2.5 and 2-fold respectively, p < 0.05).
To further elucidate the relationship between FOXM1 on EMT reversal, we then silenced FOXM1 in MDA-MB-231 cells and evaluated its effect on the EMT-associated markers. Again we noted upregulation of E cadherin (3.5-fold, p< 0.01) and down-regulation of vimentin (4.5-fold, p <0.01) in FOXM1, which was very similar to what was observed in the PP-treated MDA-MB-231 cells.
Conclusion: These studies show, for the first time, the role of FOXM1 in EMT reversal in breast cancer cells. Furthermore, it shows that use of an NF-kB inhibitor, such as panepoxydone, may be helpful in elucidating the relationship between these two transcriptional factors, in the reversal of the EMT phenotype in aggressive breast cancer cells.

Abstract
In this study the nucleotide diversity in the 5'untranslated region (UTR) of TLR8 gene in riverine as well as swamp buffaloes has been described. Analysis of the 5'UTR of TLR8 gene showed presence of two SNPs in this region, g.-139G>T and g.-128A>G. A PCR-RFLP assay designed for genotyping of g.-139G>T SNP across 667 samples from 2 buffalo populations revealed a striking difference in allele frequency distribution across the swamp and riverine buffaloes. The frequency of T allele was higher in swamp buffalo as compared to riverine buffalo, ranging from 0.71 to 1. The G allele on the other hand exhibited a higher frequency across all the Indian riverine buffalo breeds/populations. The principal component analysis revealed separate clusters for the riverine and swamp buffaloes, as expected; however, the riverine type Assamese buffalo population of eastern India formed a distinct cluster. Since most of the buffalo populations in the eastern region are swamp type, this demarcation may be related to the difference in immune response in riverine and swamp buffaloes. These preliminary results indicate that the genetic variation observed in 5'upstream region of TLR8 gene, which differentiates swamp and riverine buffalo, needs to be further explored for association with disease susceptibility in buffalo, an important dairy and meat animal of Southeast Asia.

Abstract
Congenital granular cell lesion (CGCL) is a rare non-neoplastic lesion found in newborns also known as Neumann's tumor. This benign lesion occurs predominantly in females mostly as a single mass. The histogenesis and natural history of the lesion remains obscure. It arises from the mucosa of the gingiva, either from the maxillary or mandibular alveolar ridge. The lesion is more common in the maxillary alveolar ridge than the mandibular.The present report describes a case of congenital granular cell lesion in an eight-day-old female child who was born with a mass on the anterior mandibular alveolar ridge. The mass was protruding from her mouth and compromised feeding. A clinical diagnosis of teratoma was suggested. Histologically, cells of this lesion are identical to granular cell tumor (neuroectodermal type) and show intense diastase-resistant Periodic Acid Schiff positivity. Immunohistochemically, cells are positive for vimentin but negative for S-100 and desmin, thus suggesting that CGCL is possibly derived from primitive gingival mesenchymal cells rather than having schwannian origin.
