Abstract
Animal species detection is one of the crucial steps for consumer's food analysis. In the present study we developed an in-house built loop-mediated isothermal amplification (LAMP) assay for rapid detection of adulterated cow DNA in goat milk/meat samples. The cow milk/tissue DNA in goat milk/meat samples were identified in the developed LAMP assay by either naked eye visualizing with SYBR Green I dyes or by detecting the typical ladder pattern on gel electrophoresis. This test can detect up to minimum 5% level of cow components admixed in goat milk/meat samples and can be completed within 1 h 40 min starting from DNA extraction from milk/meat samples and can be performed in a water bath. Developed LAMP methodology is simple; rapid and sensitive techniques that can detect adulterant like cow components in goat milk/meat are more accurate than other existing DNA based technologies.

Abstract
Dopamine (DA) has emerged as a potent inhibitory neuromodulator of luteinsing hormone (LH) secretion and reproduction in teleosts. The DA neurones located in the anterior subdivision of nucleus preopticus periventricularis (NPPa) in the preoptic area (POA) innervate the pituitary gland and regulate LH cells. Although a reduction in the inhibitory DAergic tone is crucial for stimulatory action of gonadotrophin-releasing hormone (GnRH) on LH cells, the role of other hypothalamic factors is suggested but not fully understood. Nonapeptide, isotocin (IST) has emerged as a likely candidate that may also influence the LH cell function. IST neurones reside in the nucleus preopticus and innervate LH cells. While IST treatment dramatically elevated LH secretion, the IST levels in brain peaked during spawning. In a pilot study on the catfish, Clarias batrachus, we observed a dense network of IST-immunoreactive (IST-IR) fibres in the NPPa, the region known to harbour hypophysiotropic DA neurones. Application of the double immunofluorescence method showed a dense IST-IR fibre network around the tyrosine hydroxylase-immunoreactive (TH-IR) neurones in the NPPa region. A great majority of the TH-IR neurones in the NPPa were contacted by IST-IR fibres during the spawning phase. The NPPa therefore appears to be a site for the intense interaction of DA and IST. IST-IR fibre innervation in NPPa showed reproduction phase-dependent changes. The percent fluorescent area of IST-IR fibres showed a gradual increase from the resting through prespawning phases (resting: 7.5 ± 1.04; preparatory: 8.6 ± 0.8; prespawning: 15.5 ± 1.4), reaching a peak in the spawning phase (28 ± 2.3; P < 0.001). Compared to the spawning phase, a drastic reduction in IST-IR fibres in the NPPa was observed during the postspawning phase (8.4 ± 0.9; P < 0.001). Superfused slices of the POA of C. batrachus treated with IST peptide resulted in a significant reduction in TH immunoreactivity in the NPPa (Control: 45.3 ± 4.2; IST peptide, 5 μm: 29.4 ± 4.7; P < 0.05). We suggest that the intense interaction between IST and DA in the NPPa, most probably of an inhibitory nature, may be critical for the regulation of LH cells and reproduction in teleosts.

Abstract
INTRODUCTION Oral Submucous Fibrosis (OSMF) is one of the most prevalent potentially malignant disorders seen in South east population since ages. Despite the extensive amount of research held in this field, its treatment still remains a challenge. In this study, we present our experience in successfully managing OSMF with intralesional injections of a peripheral vasodilator namely xantinol nicotinate. AIM To determine the efficacy and safety of intralesional xantinol nicotinate in the treatment of various stages of OSMF. MATERIALS AND METHODS This parallel, prospective, clinical study included 60 patients clinically diagnosed with oral submucous fibrosis divided into two groups. Group I patients were subjected to intralesional xantinol nicotinate injections bi-weekly for a period of four months while Group II patients were given intralesional saline injections biweekly for four months. All the patients were instructed to perform home mouth opening physiotherapy exercises. At each visit, parameters like increase in interincisal distance, cheek flexibility, tongue protrusion and relief from burning sensation and any side effects were measured and recorded. The drop out figure was zero. RESULTS At the end of four months, in Group I, there was an increase in mean values of interincisal distance, cheek flexibility and tongue protrusion (p<0.001). For burning sensation a significant decrease in mean value was observed (p<0.001). Whereas, in Group 2 the difference between pre-treatment and post-treatment values was not statistically significant (p>0.001). On comparing the results of Group 1 and Group 2, statistically significant difference was observed (p<0.001). CONCLUSION Xantinol nicotinate, a peripheral vasodilator, when injected intralesionally in OSMF patients not only provides relief from burning sensation but also results in increased mouth opening, tongue protrusion and cheek flexibility.

Abstract
BACKGROUND Orbital involvement in Wegener's Granulomatosis (WG) is rare and has an overall good prognosis. CASE A 60-year-old hypertensive Indian female presented with vision loss and painful proptosis of left eye. Orbital incisional biopsy suggested necrotising small vessel inflammation. The saddle nose deformity and pedal nodulo- ulcerative lesions further consolidated the diagnosis of Wegener's granulomatosis. Systemic immunosuppressant provided remission and the only relapse was managed successfully with intravenous Rituximab. CONCLUSION Wegener's granulomatosis should be kept in the differential diagnosis of painful proptosis with a diffuse orbital mass in an elderly patient presenting with profound vision loss. Newer immune modulating agents are useful adjuncts in preventing relapses of this fatal disease.

Abstract
The incidence of acute kidney injury (AKI) in pregnancy is declining in developing countries but still remains a major cause of maternal and fetal morbidity and mortality. The aim of the study was to analyze the changing trends in pregnancy related AKI (PR-AKI) over a period of thirty-three years. Clinical characteristics of PR-AKI with respect to incidence, etiology and fetal and maternal outcomes were compared in three study periods, namely 1982-1991,1992-2002 and 2003-2014. The incidence of PR-AKI decreased to 10.4% in 1992-2002, from 15.2% in 1982-1991, with declining trend continuing in 2003-2014 (4.68%).Postabortal AKI decreased to 1.49% in 2003-2014 from 9.4% in 1982-1991of total AKI cases. The AKI related to puerperal sepsis increased to 1.56% of all AKI cases in 2003-2014 from 1.4% in 1982-1991. Preeclampsia/eclampsia associated AKI decreased from 3.5% of total AKI cases in 1982-1991 to 0.54% in 2003-2014. Pregnancy associated – thrombotic microangiopathy and acute fatty liver of pregnancy were uncommon causes of AKI. Hyperemesis gravidarum associated AKI was not observed in our study. Incidence of renal cortical necrosis (RCN) decreased to 1.4% in 2003-2014 from 17% in 1982-1991.Maternal mortality reduced to 5.79% from initial high value 20% in 1982-1991. The progression of PR-AKI to ESRD decreased to1.4% in 2003-2014 from 6.15% in 1982-1991. The incidence of PR-AKI has decreased over last three decades, mainly due to decrease in incidence of postabortal AKI. Puerperal sepsis and obstetric hemorrhage were the major causes of PR-AKI followed by preeclampsia in late pregnancy. Maternal mortality and incidence and severity of RCN have significantly decreased in PR-AKI. The progression to CKD and ESRD has decreased in women with AKI in pregnancy in recent decade. However, the perinatal mortality did not change throughout study period.

Abstract
Diabetes mellitus is a major source of mortality and morbidity along with an economic menace all over the world. In 2000, prevalence of diabetes worldwide was 171,000,000 and in 2030, it will be 366,000,000, nearly one in ten people globally will have some form of diabetes by 2035. There are some 382 million people living with the disease, but that could jump 55% by 2035. The total number of people in India with diabetes to be around 50.8 million in 2010, rising to 87.0 million by 2030 and it is estimated that by 2040 the numbers will increase upto 123.5 million. It has estimated that the prevalence of diabetes in rural populations is one-quarter that of urban population for India and other Indian sub-continent countries such as Bangladesh, Nepal, Bhutan, and Sri Lanka. Indian Council of Medical research (ICMR) revealed that a lower proportion of the population is affected in states of Northern India (Chandigarh 0.12 million, Jharkhand 0.96 million) as compared to Maharashtra (9.2 million) and Tamil Nadu (4.8 million). The National Urban Survey conducted across the metropolitan cities of India reported similar trend: 11.7 per cent in Kolkata (Eastern India), 6.1 per cent in Kashmir Valley (Northern India), 11.6 per cent in New Delhi (Northern India), and 9.3 per cent in West India (Mumbai) compared with (13.5 per cent in Chennai (South India), 16.6 per cent in Hyderabad (south India), and 12.4 per cent Bangalore (South India). Strengthening of health promotion activitiesin different settings, preventive health screening package, better treatment facilities and effective implementation can cure these problems worldwide.

Abstract
Lichen planus is a chronic, autoimmune, mucocutaneous disease that shows differences in clinical presentation at different times of the year. The present retrospective study was conducted to clarify the meteorological factors that influence the incidence of lichen planus, as well as the general features and clinical presentation of this condition during three consecutive years, 2008, 2009, and 2010, in Moradabad district (Western Uttar Pradesh, India). The study group comprised 1,355 patients extracted from the records of the outpatient department of Kothiwal Dental College Research Centre and Hospital, who were clinically diagnosed as having lichen planus during this three-year period. The highest number of patients (735) were recorded in summer, and the lowest (56) in winter. Females were affected more often, and psychosocial influences were also evident. There were significant differences in the incidence of lichen planus in different seasons, and the summer peak was attributable to the intensity of sun exposure (actinic lichen planus and summertime lichen planus).

Abstract
Trends showing drug-resistance pattern are needed to understand direction of tuberculosis (TB) control programme. The drug-resistance pattern in state of Uttar Pradesh, India, is not documented. Here we are reporting the prevalence of multi-drug-resistant (MDR) and drug-resistant TB in previously treated cases of pulmonary tuberculosis following launch of revised national TB control programme (RNTCP) in whole of Uttar Pradesh. Isolates of Mycobacterium tuberculosis, from patients of pulmonary tuberculosis, who were treated with antitubercular drugs for more than 4 weeks, were tested for resistance to first-line drugs; streptomycin (S), Ethambutol (E), Rifampicin (R) and isoniazid (H) over a period of 4 years, 2009-2012. Total 2496 isolates of M. tuberculosis were tested, of which 1139 isolates (45.6%) were pan-sensitive and 370 (14.8%) were pan-resistant. Total 695 isolates (27.8%) were MDR. Maximum resistance was with Isoniazid (n=1069, 42.8%) followed by streptomycin (n=840, 33.7%), rifampicin (n=742, 29.7%), and ethambutol (n=613, 24.6%). A decline in number of MDR strains and individual drug resistance was seen. Total MDR strains in the year 2009, 2010, 2011 and 2012 were 35.6%, 30.8%, 26.7% and 22.8% respectively. The drug resistance pattern reported from time to time may vary substantially. The decline in drug resistance visible over last four years, after implementation of DOTS, appears promising.

Abstract
Mammalian circadian locomotor output cycles kaput (CLOCK) gene encodes a transcription factor that affects both the persistence and the period of circadian rhythms. Earlier reports suggested that CLOCK gene might be associated with male infertility in human. Present investigation, for the first time, reports that CLOCK gene expresses differentially between good and poor quality crossbred bull semen. The relative expression of CLOCK was significantly (p < 0.05) higher among good quality bull semen than motility-impaired ones. Clusterins (CLU) are series of genes associated with a variety of physiological activities including spermatogenesis, apoptosis and degenerative disease conditions. In the present context, we also investigated that the expression of CLU gene was significantly (p < 0.05) higher among motility-impaired crossbred bull semen compared to the good quality one.

Abstract
Dopamine (DA) inhibits, whereas gonadotrophin-releasing hormone (GnRH) stimulates, luteinisiing (LH) cells in the pituitary of some but not all teleosts. A reduction in the hypophysiotropic dopaminergic tone is necessary for the stimulatory effect of GnRH on LH cells. Neuropeptide Y (NPY) has emerged as one of the potent, endogenous agent that modulates LH secretion directly or indirectly via GnRH. Involvement of NPY in the regulation of hypophysiotropic DA neurones, however, is not known, but there is good evidence suggesting an interaction in the mammalian hypothalamus. DA neurones, identified by tyrosine hydroxylase (TH)-immunoreactivity, were observed widely throughout the brain of the Indian major carp, Cirrhinus cirrhosus. The granule cells and ganglion cells of terminal nerve in the olfactory bulb, and cells in ventral telencephalon and preoptic area (POA) showed conspicuous TH immunoreactivity. In the POA, the nucleus preopticus periventricularis (NPP), divisible into anterior (NPPa) and posterior (NPPp) components, showed prominent TH-immunoreactivity. The majority of TH neurones in NPPa showed axonal extensions to the pituitary and were closely associated with LH cells. The NPPa also appeared to be the site for intense interaction between NPY and DA because it contains a rich network of NPY fibres and few immunoreactive cells. Approximately 89.7 ± 1.5% TH neurones in NPPa were contacted by NPY fibres. Superfused POA slices treated with a NPY Y2 -receptor agonist, NPY 13-36 resulted in a significant (P < 0.001) reduction in TH-immunoreactivity in NPPa. TH neurones in NPPa did not respond to NPY Y1 -receptor agonist, [Leu(31) , Pro(34) ] Neuropeptide Y treatment. We suggest that, by inhibiting DAergic neurones in NPPa via Y2 -receptors, NPY may contribute to the up-regulation of the GnRH-LH cells axis. The microcircuitry of DA and NPY and their interaction in NPPa might be a crucial component in the central regulation of LH secretion in the teleosts.

The aim of the present study was to screen the genotype profile of bovine kappa-casein gene among Frieswal (HF × Sahiwal) crossbred cattle developed in India. A total number of two hundred Frieswal cows were evaluated for HinfI RFLP based genotyping of kappa-casein gene. We observed that only two genotypes (AA and AB) exist among the studied population with the genotype frequency of 0.58 (n=117) and 0.42 (n=83), respectively. The calculated allele frequency for A and B was 0.79 and 0.21, respectively. Association of genotypes with certain milk production traits revealed that AB had significant (P<0.05) effect on total milk yield, peak yield, yield at 300 days and SNF% as compared to AA.

Abstract
This study was undertaken to compare the effect of oxytocin and human chorionic gonadotrophin (hCG) on ovulation and conception. A total of 100 women with anovulatory infertility were allocated into two equal groups to take clomiphene citrate plus hCG or clomiphene citrate plus oxytocin. The size and number of follicles by transvaginal sonography determined the administration of hCG or oxytocin. The serum progesterone concentration was measured to provide evidence for ovulation. The ovulation and pregnancy rate of the two groups were compared. There was no significant difference between the groups with respect to mean number of follicles, mean follicular size and rate of ovulation in three cycles. The rate of pregnancy was higher in the oxytocin group compared with the hCG group (12% vs 4%) but it failed to reach statistical difference (p = 0.140). Mild pain was the only side-effect observed in the two groups. Oxytocin was found to be a viable alternative to hCG for triggering ovulation in infertile patients.

Abstract
MicroRNAs (miRNAs) are small non-coding RNAs that modulate gene expression by binding to complementary sequences on target messenger RNA transcripts. Changes in the expression levels of specific miRNAs have been associated with a variety of disease conditions. We developed a reliable and high throughput in situ hybridization (ISH) method and optimized tissue fixation conditions for formalin fixed, paraffin embedded (FFPE) tissues. ISH methods were automated to visualize four miRNAs: miRNA-145 (smooth muscle cells), miRNA-126 (endothelial cells), miRNA-21 (neoplastic cells) and U6 small nuclear RNA (nuclear marker) using locked nucleic acid (LNA) probes and the Discovery Ultra Ventana(™) platform. The FFPE tissue sections were pretreated with protease 3, hybridized with probe concentrations of ≤ 25 nM; signal was detected using an enhanced, polymer-based detection method. The ISH signal was stronger and more uniform for tissue samples fixed for ≥ 48 h. To investigate the specificity of the method, we developed an automated dual ISH for miRNA-145 coupled with immunohistochemistry for smooth muscle actin, which confirmed the specific distribution of miRNA-145 to smooth muscle cells. These methods may be used routinely for exploratory studies of biomarker development, sample screening and understanding the role of miRNA in the pathophysiology of specific diseases.

Abstract
Hereditary gingival fibromatosis is a rare condition characterised by severe gingival hyperplasia that can occur as an isolated disease or as part of a syndrome or chromosomal abnormality. In severe cases, the gingival enlargement may cover the crowns of teeth and cause severe aesthetic, emotional and functional impairment. This case report gives an overview of gingival fibromatosis in a 22-year-old male patient who presented with generalised gingival enlargement.
