Abstract
BACKGROUND Low- and middle-income countries have a critical shortage of specialist anaesthetists. Most patients arriving for surgery are of low perioperative risk. Without immediate access to preoperative specialist care, an appropriate interim strategy may be to ensure that only high-risk patients are seen preoperatively by a specialist. Matching human resources to the burden of disease with a nurse-administered pre-operative screening tool to identify high-risk patients who might benefit from specialist review prior to the day of surgery may be an effective strategy. OBJECTIVE To develop a nurse-administered preoperative anaesthesia screening tool to identify patients who would most likely benefit from a specialist review before the day of surgery, and those patients who could safely be seen by the anaesthetist on the day of surgery. This would ensure adequate time for optimisation of high-risk patients preoperatively and limit avoidable day-of-surgery cancellations. METHODS A systematic review was conducted to identify preoperative screening questions for use in a three-round Delphi consensus process. A panel of 16 experienced full-time clinical anaesthetists representing all university-affiliated anaesthesia departments in South Africa participated to define a nurses' screening tool for preoperative assessment. RESULTS Ninety-eight studies were identified, which generated 79 questions. An additional 14 items identified by the facilitators were added to create a list of 93 questions for the first round. The final screening tool consisted of 81 questions, of which 37 were deemed critical to identify patients who should be seen by a specialist prior to the day of surgery. CONCLUSION A structured nurse-administered preoperative screening tool is proposed to identify high-risk patients who are likely to benefit from a timely preoperative specialist anaesthetist review to avoid cancellation on the day of surgery.

Abstract
Background Living with hypertension (HTN) has been found to cause distress, which adversely affects one's self-care and may lead to elevated blood pressure. There is a paucity of data regarding the prevalence of HTN-related distress. This study was conducted to estimate the prevalence of HTN-related distress among adults with HTN attending an outpatient department in an urban primary health centre and to determine the factors associated with distress. Methods This was a cross-sectional study conducted at the outpatient department of an urban primary health centre in Delhi, India. The enrolled participants were administered a questionnaire, which included a Distress Scale for patients with diabetes mellitus and/or hypertension (DSDH17 M) (to assess for HTN-related distress) and Health-Related Quality of Life, Healthy Days Measure. A descriptive analysis was performed. Factors associated with HTN-related distress were tested using logistic regression. Results One hundred forty-one participants were enrolled in this study. Most were women (73.76%) with a mean age of 60.15 years (standard deviation [SD]: 0.78). The prevalence of HTN-related distress (average DSDH17 M score ≥3) was 14% (95% confidence interval [CI]: 9.30-21.03). Patients with HTN-related distress had significantly poor health and reported a greater number of days where they were physically or mentally unhealthy. Patients with uncontrolled blood pressure had six times the odds (95% CI: 1.69-21.77, P value = 0.006) of HTN-related distress compared to those with controlled blood pressure. Conclusions Hypertension-related distress was present in 14% of adults with HTN. Patients with uncontrolled blood pressure had six times the odds of HTN-related distress.

Abstract
Background DNA testing in the cattle industry undergoes multiple hurdles. Successful genotyping involves the transportation of samples from the field to the laboratory in a chilled environment followed by DNA extraction, and finally, a specific genotyping protocol is followed. Various researches are focused on overcoming these issues. Microcards offer blood transportation at ambient temperature. Direct PCR methods can save the time of DNA extraction but available only for simplex PCR. Tetra Primer-Amplification Refractory Mutation System based Polymerase Chain Reaction (T-ARMS PCR) can make DNA testing faster in a low-cost setting. The present study was aimed to design, optimize, and validate a T-ARMS PCR for faster DNA testing of SNP responsible for Complex Vertebral Malformation (CVM)-an important genetic disease of the cattle industry. Further, a direct T-ARMS PCR from whole blood was developed to avoid the DNA extraction steps. Lastly, using the optimized protocol, genotyping of blood spotted on Microcard eliminates the need for cold chain maintenance in the transportation of samples. Results The present study demonstrated a novel T-ARMS PCR-based genotyping of the SNP rs438228855, which is responsible for CVM. Here, wild genotypes were recognized by 389 bp and 199 bp bands in agarose gel, while the carrier genotype showed an additional 241 bp band. The developed protocol was validated using PCR-Primer Introduced Restriction Analysis (PCR-PIRA) and sequencing. The present study further established a direct T-ARMS PCR for this SNP from whole blood. Different conditions such as heparin and EDTA treated blood, the need for pre-treatment, and two different DNA Polymerases for the direct PCR were optimized. Finally, our optimized protocol successfully genotyped the whole blood samples dried on Insta™DNA cards. Conclusions The present study reported the usefulness of primer modified T-ARMS PCR for detecting CVM for the first time. To the best of our knowledge, direct PCR in T-ARMS PCR has never been reported. Lastly, the use of microcards in the developed protocol can make the assay useful in the DNA testing of field samples.

Abstract
Abstract
Introduction
Cancer is likened to a non-healing wound. There is limited evidence on the expression of wound healing tissue inflammatory markers, CD68(pan-macrophage marker), HO-1(tumour cell marker) and FAP(cancer-associated fibroblast marker) in human breast cancer.
Method
In 201 invasive breast cancer and 58 DCIS patients, CD68+TAM expression, tumour HO-1 and fibroblast FAP expression, quantified by immunohistochemistry(dichotomised: high/present vs low/absent), was correlated with tumour factors (grade, proliferation(Ki67), ER, HER2); demographic factors, behavioural factors (smoking, alcohol) and survival status(DFS, OS)
Result
High CD68+macrophage expression was increased in invasive breast cancer, compared to DCIS, and normal tissue distant from the tumour(59%,41%and 6% respectively; p<0.001).In invasive cancer,CD68+TAM expression increased with increasing tumour grade(Grade 1:42%, Grade 2:58%, Grade 3:72%; p=0.006), high Ki67(71%vs.47%; p=0.004), ER negativity(79.4%vs.55.4%; p=0.01) and HER2(HER2 positive 81.8% vs. HER2 negative 56.3%; p=0.03). CD68+TAM expression was higher in high compared to low/intermediate grade DCIS(44% % vs. 31% p=0.52). CD68+TAM expression was increased in patients who self-reported alcohol intake(non-drinker 43% vs. drinker 62%; p=0.01). HO-1 was associated with shorter DFS(HR:3.22,p=0.027) and OS(HR:2.86,p=0.029).FAP fibroblast expression correlated with longer DFS (HR:0.296,p=0.029) and OS (HR:0.271,p=0.008).
Conclusion
Tumour inflammation as assessed by CD68+TAM expression shows utility in identifying aggressive breast cancer sub-types. The association reported between CD68+TAM density and alcohol intake suggests a possible mechanism for alcohol as a risk factor for breast cancer. The prognostic value of HO-1 and FAP expression demonstrated here suggests a functional role of these wound healing markers in breast cancer. HO-1:Heme-oxygenase-1; FAP:Fibroblast activation protein; TAM:Tumour associated macrophage; DCIS: Ductal carcinoma in situ
Take-home message
Wound healing pathways of inflammation may be implicated in early breast cancer development

Abstract
Background: Osteoarthritis (OA) is the most common type of arthritis and a very common disease of elderly. It is one of the leading causes of disability. The present study was conducted to estimate the burden of the knee OA among rural elderly. Methods: A community-based cross-sectional study was conducted among 500 randomly selected elderly resident of rural Ballabgarh, Haryana. A semi-structured interview schedule was used by a trained investigator for face-to-face interview, clinical examination of knee using American College of Rheumatology criteria, and quality of life assessment using WHOQOL-BREF. Results: Almost two-third of the participants among 454 elderly recruited, suffered from knee OA (292, 64.3%) had knee OA. History of a knee injury, a family history of knee pain, current physical activity and smoking status were found to be significantly associated with knee OA, in multivariate logistic regression model. Elderly suffering from knee OA had significantly lower quality-of-life scores contrasted to those not (p-value < 0.001). The scores were significantly lower for all the domains (P-value <0.001) among elderly suffering with the knee OA, with the maximum effect seen in psychological, and physical domain. Conclusion: Rural elderly of Ballabgarh, Haryana, had a high burden of knee OA. Elderly suffering from knee OA had significantly lower perception of their quality of life most affected is the psychological and physical domains of quality of life.

Abstract
Flow coefficients v_{n} of the orders n=1-6 are measured with the High-Acceptance DiElectron Spectrometer (HADES) at GSI for protons, deuterons, and tritons as a function of centrality, transverse momentum, and rapidity in Au+Au collisions at sqrt[s_{NN}]=2.4 GeV. Combining the information from the flow coefficients of all orders allows us to construct for the first time, at collision energies of a few GeV, a multidifferential picture of the angular emission pattern of these particles. It reflects the complicated interplay between the effect of the central fireball pressure on the emission of particles and their subsequent interaction with spectator matter. The high precision information on higher order flow coefficients is a major step forward in constraining the equation of state of dense baryonic matter.

Abstract
Fibromyalgia is a multi-symptomatic disorder characterized by generalized pain. The pathophysiology of fibromyalgia is supposedly an interplay between central nervous system hyper-responsiveness, autonomic dysfunction, and peripheral pain. In this cross-sectional study, the objective was to assess central sensitization and autonomic activity in patients with fibromyalgia compared with control. Fifty adults diagnosed with fibromyalgia by the modified American College of Rheumatology 2010 criteria and an equal number of age- and sex-matched controls participated in the study in an urban tertiary care hospital. Central sensitization was assessed by history and by evidence of increased prefrontal cortical activity as measured by cortical oxygenation using functional near-infrared spectroscopy. Autonomic activity was assessed by heart rate variability, electrodermal activity, and deep breathing test in three physiological states: rest, sympathetic stress (cold pressor test), and deep breathing. Mann–Whitney U-test, paired t-test, Wilcoxon test, and Friedman test with Bonferroni a priori were used to analyze the data. Cortical activity was significantly higher in the fibromyalgia group than control. There was no significant difference in autonomic activity between the fibromyalgia and control groups. In the fibromyalgia group, variable degrees of sympathetic hyperactivity and normal parasympathetic activity were observed. Central sensitization may be playing a primary role in the pathophysiology of generalized pain in fibromyalgia.

Abstract
Firefighters perform physically intensive jobs in suboptimal environments, making it even more important for them to maintain good functional postural balance or stability. As part of their training, firefighters are required to perform physically demanding tasks under high stress and high heat environments. These demanding tasks lead to increased physical fatigue which can then result in poor performance and/or postural instability. The objectives of this study were to 1) investigate the effect of live-firefighting training-induced heat stress on static postural balance, and 2) investigate the association between commonly monitored physiological responses (core body temperature, heart rate, oxygen saturation and blood pressure) and measures of static postural balance. Twenty-six firefighters (mean ± SD: age 36.0 years ±5.2, weight 216 lbs. ± 34, BMI 29.7 ± 4.2) participated in live firefighting training while performing following tasks: search and rescue, hose advancement, and backup. Prior to heat exposure (PRE) and following each scenario (POST1, POST2, POST3), firefighters' postural balance was assessed with a wearable 3-D inertial sensor system quantifying time dependent changes in linear acceleration (LIN ACC) and angular velocity (AV) about three orthogonal axes [Anterior-Posterior (AP), Medial-Lateral (ML), and vertical (V)] during one foot balance tests for 30 seconds under eyes open and eyes closed conditions. The outcome variables from 3-D wearable sensors were used to create 3-D Phase-Plane based postural stability metrics. Physiological measurement of core body temperature (CBT) (measured with a radio pill) as well as perception of heat increased significantly during the live fire-training exercise. In addition, firefighters also perceived an increase in physical fatigue and respiratory distress. Angular combined stability parameters (ACSP), RMS angular velocity around ML axis were significantly correlated with CBT. In the multivariate analysis adjusted for the scenarios, height and weight of the firefighters, these measures of static postural balance were significantly associated with CBT. As per the model results, static postural balance, as indicated by ACSP, worsened with an increase in CBT. Future studies should place sensors at body extremities along with close to center of mass to capture the kinematic movements more comprehensively influencing postural balance.

Abstract
Propofol causes pain on intravenous injection in 28 to 90% of patients. A number of techniques have been tried to minimize propofol-induced pain, with variable results. In a randomized, double-blind, placebo-controlled trial, we compared the efficacy of ephedrine 30 μg/kg pretreatment to lignocaine 40 mg for prevention of propofol-induced pain. Ninety-three adult patients, ASA 1 and 2, undergoing elective laparoscopic cholecystectomy were randomly assigned to three groups of 31 each. Group 1 received normal saline, group 2 received lignocaine 2% (40 mg) and group 3 received 30 μg/kg ephedrine. All pretreatment drugs were made up to 2 ml. Pain at the time of propofol injection was assessed on a four-point scale: 0=no pain, 1=mild pain, 2=moderate pain, and 3=severe pain. Twenty-seven patients (87%) of ephedrine pretreatment patients had pain during intravenous injection of propofol as compared to 24 (77%) in the normal saline group. In the lignocaine group, propofol-induced pain was observed in only 13 (42%) when compared with other study groups (P<0.05). Pretreatment with ephedrine 30 μg/kg did not attenuate pain associated with intravenous injection of propofol, nor did it improve haemodynamic stability during induction. However, pretreatment with 2% lignocaine (40 mg) was effective in attenuating propofol-associated pain.

Abstract
Tumor infiltrating lymphocytes (TIL), especially T-cells, have both prognostic and therapeutic applications. The presence of CD8+ effector T-cells and the ratio of CD8+ cells to FOXP3+ regulatory T-cells have been used as biomarkers of disease prognosis to predict response to various immunotherapies. Blocking the interaction between inhibitory receptors on T-cells and their ligands with therapeutic antibodies including atezolizumab, nivolumab, pembrolizumab and tremelimumab increases the immune response against cancer cells and has shown significant improvement in clinical benefits and survival in several different tumor types. The improved clinical outcome is presumed to be associated with a higher tumor infiltration; therefore, it is thought that more accurate methods for measuring the amount of TIL could assist prognosis and predict treatment response. We have developed and validated quantitative immunohistochemistry (IHC) assays for CD3, CD8 and FOXP3 for immunophenotyping T-lymphocytes in tumor tissue. Various types of formalin fixed, paraffin embedded (FFPE) tumor tissues were immunolabeled with anti-CD3, anti-CD8 and anti-FOXP3 antibodies using an IHC autostainer. The tumor area of stained tissues, including the invasive margin of the tumor, was scored by a pathologist (visual scoring) and by computer-based quantitative image analysis. Two image analysis scores were obtained for the staining of each biomarker: the percent positive cells in the tumor area and positive cells/mm2 tumor area. Comparison of visual vs. image analysis scoring methods using regression analysis showed high correlation and indicated that quantitative image analysis can be used to score the number of positive cells in IHC stained slides. To demonstrate that the IHC assays produce consistent results in normal daily testing, we evaluated the specificity, sensitivity and reproducibility of the IHC assays using both visual and image analysis scoring methods. We found that CD3, CD8 and FOXP3 IHC assays met the fit-for-purpose analytical acceptance validation criteria and that they can be used to support clinical studies.

Abstract
Context: Identification using DNA has proved its accuracy multiple times in the field of forensic investigations. Investigators usually rely on either teeth or bone as the DNA reservoirs. However, there are instances where the skeletal or dental remains are not available or not preserved properly. Moreover, due to religious beliefs, the family members of the dead do not allow the investigating team to damage the remains for the sole purpose of identification. Aim: To investigate the presence of human DNA in dental calculus and to quantify the amount, if present. Materials and Methods: This prospective single-blinded pilot study included twenty subjects selected from the patients visiting a dental college. The samples of dental calculus were collected from the thickest portion of calculus deposited on the lingual surfaces of mandibular incisors. These samples were decontaminated and subjected to gel electrophoresis for DNA extraction. Results: DNA was found in 85% cases. The amount of DNA varied from 21 to 37 μg/ml of dental calculus. Conclusion: Dental calculus is a rich reservoir of human DNA.

Abstract
2', 5'-Oligoadenylate synthetases (OAS) are important components of an interferon-mediated antiviral pathway. No polymorphisms in exonic regions of bovine OAS1 gene have been identified and associated with reproduction traits. The objective of the study was to detect and evaluate the effects of mutations in exonic region of bovine OAS1 gene with reproduction traits in cattle. DNA samples collected from 250 individual cows of two Indian dairy breeds (Sahiwal and Frieswal) of cattle were used in the study. The genetic variants of the OAS1 gene were identified with polymerase chain reaction-single-strand conformation polymorphism (PCR-SSCP) and sequence analysis using seven set of primer pairs. The PCR-SSCP analysis revealed polymorphism in the fragments comprising of exon 2, exon 5 and first fragment of exon 6 while the fragments of exons 1, 3, 4 and second fragment of exon 6 were monomorphic in Sahiwal and Frieswal cattle. The mutations in the amplified region comprising of exon 2 were found to have significant association with age at first breeding and calving, service period, dry period and pregnancy rate. Significant associations were found between SNPs in the exon 5 and service and dry periods of the animal, whereas the genetic variants in the first fragment of the exon 6 showed significant association with age at first breeding and calving. To our knowledge, this study demonstrated for the first time that the polymorphisms in OAS1 gene were associated with reproductive traits and it can be chosen as a candidate gene for improvement of reproductive performance of cattle.

Abstract
INTRODUCTION Osteoarthritis (OA) of knee is a common joint disease. It is associated with reduced knee joint stability due to impaired quadriceps strength, pain, and an altered joint structure. There is altered muscle activation in knee OA patients, which interferes with normal load distribution around the knee and facilitates disease progression. AIM Our primary aim was to determine activation patterns of the muscles i.e., quadriceps and hamstrings in knee OA patients during walking. We also studied co-activation of muscles around knee joint in primary OA knee patients including directed medial and lateral co-contractions. MATERIALS AND METHODS This observational study was done at Department of Physical Medicine and Rehabilitation, All India Institute of Medical Sciences, New Delhi, India. Fourty-four patients with medial compartment primary knee OA were included in study after satisfying inclusion and exclusion criteria. All the patients were assessed for mean, peak and integrated Root Mean Square (RMS), EMG values, muscle activation patterns and co-activation of muscles around knee joint by surface Electromyography (EMG) analysis of Vastus Medialis Obliques (VMO), Vastus Lateralis (VL), Semitendinosus (SMT) and Biceps Femoris (BF) muscles during gait cycle. The EMG waveform for each muscle was amplitude normalized and time normalized to 100% of gait cycle and plotted on graph. Quantitative variables were assessed for normal distribution and accordingly mean±SD or median (range), as appropriate, was computed. RESULTS For primary OA knee, mean age 61±5 years, mean weight 63.7±10.1 kg, mean height 153.9±7.2 cm, and mean Body Mass Index (BMI) 26.8±3.0 kg/m2 was found. The muscle activity of hamstrings (SMT muscle and BF) was increased during midstance, late stance and early swing phase of gait cycle as compared to quadriceps (VMO and VL) muscle activity respectively, suggesting co-contraction of opposing muscles around knee joint. CONCLUSION Patients with knee OA walk with increased hamstring muscle activity (during late stance and early swing phase) and reduced quadriceps recruitment. Altered neuro-muscular control around knee interferes with normal load distribution and facilitates disease progression in knee joint.

Abstract
Recent studies suggest an important role for transient receptor potential vanilloid (TRPV) ion channels in neural and neuroendocrine regulation. The TRPV subfamily consists of six members: TRPV1-6. While the neuroanatomical and functional correlates of TRPV1-4 have been studied extensively, relevant information about TRPV5 and TRPV6, which are highly selective for Ca2+ , is limited. We detected TRPV5 mRNA expression in the olfactory bulb, cortex, hypothalamus, hippocampus, midbrain, brainstem and cerebellum of the rat. TRPV5-immunoreactive neurones were conspicuously seen in the hypothalamic paraventricular (PVN), supraoptic (SON), accessory neurosecretory (ANS), supraoptic nucleus, retrochiasmatic part (SOR), arcuate (ARC) and medial tuberal nuclei, hippocampus, midbrain, brainstem and cerebellum. Glial cells also showed TRPV5-immunoreactivity. To test the neuroendocrine relevance of TRPV5, we focused on vasopressin, oxytocin and cocaine- and amphetamine-regulated transcript (CART) as representative candidate markers with which TRPV5 may co-exist. In the hypothalamic neurones, co-expression of TRPV5 was observed with vasopressin (PVN: 50.73±3.82%; SON: 75.91±2.34%; ANS: 49.12±4.28%; SOR: 100%) and oxytocin (PVN: 6.88±1.21; SON: 63.34±5.69%; ANS: 20.4±4.14; SOR: 86.5±1.74%). While ARC neurones express oestrogen receptors, 17β-oestradiol regulates TRPV5, as well as CART neurones and astrocytes, in the ARC. Furthermore, ARC CART neurones are known to project to the preoptic area, and innervate and regulate GnRH neurones. Using double-immunofluorescence, glial fibrillary acidic protein-labelled astrocytes and the majority of CART neurones in the ARC showed TRPV5-immunoreactivity. Following iontophoresis of retrograde neuronal tracer, cholera toxin β (CtB) into the anteroventral periventricular nucleus and median preoptic nucleus, retrograde accumulation of CtB was observed in most TRPV5-equipped ARC CART neurones. Next, we determined the response of TRPV5-elements in the ARC during the oestrous cycle. Compared to pro-oestrus, a significant increase (P<.001) in the percentage of TRPV5-expressing CART neurones was observed during oestrus, metoestrus, and dioestrus. TRPV5-immunoreactivity in the astrocytes, however, showed a significant increase during metoestrus and dioestrus. We suggest that the TRPV5 ion channel may serve as an important regulator of neural and neuroendocrine pathways in the brain.

Abstract
Human immunodeficiency virus (HIV) infection can cause a broad spectrum of renal diseases. However, there is paucity of Indian data on the patterns of renal lesions in HIV-seropositive patients. The aim of the present study was to delineate the spectrum of renal lesions in HIV/acquired immunodeficiency syndrome patients. In this prospective study, all HIV-positive patients of both genders aged >18 years were screened for renal disease. Patients with proteinuria of more than 1 g/24 h were subjected to renal biopsy. A total of 293 HIV-positive patients were screened; of these, 136 (46.4%) patients found to have renal involvement. Dipstick-positive proteinuria of 1+ or more was observed in 112 (38.2%) patients, and 16 (14.2%) patients had proteinuria of more than 1 g/24 h. Renal biopsy in 14 cases revealed glomerulonephritis (GN) in 12 (85.7%) (isolated GN in 4 [28.5%] and GN mixed with chronic TIN in 8 [57.1%]) patients. These include mesangioproliferative GN in 5 (35.7%), membranoproliferative GN in 2 (14.2%), focal segmental glomerulosclerosis in 2 (14.2%), diffuse proliferative GN in 2 (14.2%), and diabetic nephropathy in 1 (7.1%) patients. Chronic interstitial nephritis was noted in 10 (71.42%) (superimposed on GN in 8 [57.1%], isolated in 2 [14.2%]) patients. Granulomatous interstitial nephritis was seen in 3 (24.1%) cases. GN and chronic interstitial nephritis were noted in 85.7% and 71.42% of patients, respectively, mostly superimposed on each other. Mesangioproliferative GN was the most common glomerular lesion, but classical HIV-associated nephropathy was not observed.

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
An extra tooth causing numerical excess in dentition is described as supernumerary tooth, and the resultant condition is termed as hyperdontia. Hyperdontia is more commonly seen in the permanent dentition than primary one. Supernumerary tooth which resembles tooth shape and supplements for occlusion is called as supplemental tooth. We present a case with supplemental tooth in primary dentition.

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.

Abstract
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.
