Abstract
Development of leaf rust-resistant cultivars is a priority during wheat breeding, since leaf rust causes major losses in yield. Resistance against leaf rust due to Lr genes is partly controlled by epigenetic modifications including histone acetylation that is known to respond to biotic/abiotic stresses. In the present study, enrichment of H3K4ac and H3K9ac in promoters of six defense responsive genes (N-acetyltransferase, WRKY 40, WRKY 70, ASR1, Peroxidase 12 and Sarcosine oxidase) was compared with their expression in a pair of near-isogenic lines (NILs) for the gene Lr28 following inoculation with leaf rust pathotype '77-5'; ChIP-qPCR was used for this purpose. The proximal and distal promoters of these genes contained a number of motifs that are known to respond to biotic stresses. The enrichment of two acetylation marks changed with passage of time; changes in expression of two of the six genes (N-acetyltransferase and peroxidase12), largely matched with changes in H3K4/H3K9 acetylation patterns of the two promoter regions. For example, enrichment of both the marks matched with higher expression of N-acetyltransferase gene in susceptible NIL and the deacetylation (H3K4ac) largely matched with reduced gene expression in resistant NIL. In peroxidase12, enrichment of H3K4ac and H3K9ac largely matched with higher expression in both the NILs. In the remaining four genes, changes in H3 acetylation did not always match with gene expression levels. This indicated complexity in the regulation of the expression of these remaining four genes, which may be controlled by other epigenetic/genetic regulatory mechanisms that need further analysis.

Abstract
Leaf rust disease causes severe yield losses in wheat throughout the world. During the present study, high-throughput RNA-Seq analysis was used to gain insights into the role of Lr28 gene in imparting seedling leaf rust resistance in wheat. Differential expression analysis was conducted using a pair of near-isogenic lines (NILs) (HD 2329 and HD 2329+Lr28) at early (0h before inoculation (hbi), 24 and 48h after inoculation (hai)) and late stages (72, 96 and 168 hai) after inoculation with a virulent pathotype of pathogen Puccinia triticina. Expression of a large number of genes was found to be affected due to the presence/absence of Lr28. Gene ontology analysis of the differentially expressed transcripts suggested enrichment of transcripts involved in carbohydrate and amino acid metabolism, oxidative stress and hormone metabolism, in resistant and/or susceptible NILs. Genes encoding receptor like kinases (RLKs) (including ATP binding; serine threonine kinases) and other kinases were the most abundant class of genes, whose expression was affected. Genes involved in reactive oxygen species (ROS) homeostasis and several genes encoding transcription factors (TFs) (most abundant being WRKY TFs) were also identified along with some ncRNAs and histone variants. Quantitative real-time PCR was also used for validation of 39 representative selected genes. In the long term, the present study should prove useful in developing leaf rust resistant wheat cultivars through molecular breeding.

Abstract
Notochordal cell derived matrix (NCM) can induce regenerative effects on nucleus pulposus cells and may exert such effects on chondrocytes as well. Furthermore, when dissolved at low concentrations, NCM forms a viscous fluid with potential lubricating properties. Therefore, this study tests the feasibility of the use of NCM as a regenerative lubricant for the osteoarthritic joint. Chondrocyte-seeded alginate beads were cultured in base medium (BM), BM with NCM (NCM), or BM with TGF-β1 (TGF), as well as BM and NCM treated with IL-1β. NCM increased GAG deposition and cell proliferation (stronger than TGF), and GAG/DNA ratio and hydroxyproline content (similar to TGF). These effects were maintained in the presence of IL-1β. Moreover, NCM mitigated expression of IL-1β-induced IL-6, IL-8, ADAMTS-5 and MMP-13. Reciprocating sliding friction tests of cartilage on glass were performed to test NCM's lubricating properties relative to hyaluronic acid (HA), and showed a dose-dependent reduction in coefficient of friction with NCM, similar to HA. NCM has anabolic and anti-inflammatory effects on chondrocytes, as well as lubricating properties. Therefore, intra-articular NCM injection may have potential as a treatment to minimize pain while restoring the affected cartilage tissue in the osteoarthritic joint.

Abstract
OBJECTIVES To investigate the appearance of three esthetic nickel titanium (NiTi) wires after 6 weeks of intra-oral cycling and to determine the association between objective and subjective measures of esthetics. SETTING AND SAMPLE POPULATION A prospective cohort study was undertaken involving participants undergoing upper fixed orthodontic appliance treatment with ceramic brackets. MATERIALS AND METHODS Fifty participants were assigned to one of three groups of NiTi esthetic wires (American Orthodontics Ever White™, Forestadent Biocosmetic™ and GAC High Aesthetic™), with wires retrieved after 6 weeks in situ. Participants completed a bespoke questionnaire exploring perceptions of wire esthetics. Objective measurement of coating loss was undertaken using a custom arch wire jig. RESULTS American Orthodontics Ever White™ had the greatest mean coating loss (50.7%) followed by Forestadent Biocosmetic™ (6%), with GAC High Aesthetic TM undergoing minimal loss (0.07%) (P < .001). The majority of coating loss with the American Orthodontics Ever White™ wires arose in the anterior region while Forestadent Biocosmetic™ wires and GAC High Aesthetic™ wires exhibited coating loss posteriorly (P < .001). These findings were reflected in the subjective assessment with a negative correlation found between coating loss and final Visual Analogue Scale scores (P < .001). CONCLUSIONS Considerable esthetic variation between arch wires following 6 weeks of intraoral cycling was identified in this prospective cohort study. Intraoral cycling has a negative impact on participant perception of arch wire esthetics, and objective and subjective assessment of wire esthetics appears to be consistent.

Abstract
This study describes the influence of parasitism (Trypanosoma lewisi and Cysticercus fasciolaris) on the condition factor, hepato and splenosomatic indices of the common house rat, Rattus rattus Linnaeus, 1758 from Rohilkhand, Uttar Pradesh, India. Examination of R. rattus (n = 389) revealed T. lewisi (prevalence 12.40 %; intensity14 parasites/1000 RBC) from the blood and C. fasciolaris (larval Taenia taeniaeformis) (prevalence 46.70 %; intensity 2-4 par/host) from the liver. Condition factor (K) and organosomatic indices [hepatosomatic index, spleenosomatic index (SSI)] were evaluated in two groups (Group I non pregnant, Group II pregnant) of female rats which were further subdivided into four subgroups each (a Uninfected, b T. lewisi infected, c C. fasciolaris infected, d T. lewisi and C. fasciolaris infected) belonging to three weight groups (A 50-100 g; B 100-150 g; C 150-200 g). The results indicated that reduction in K-factor was more apparent in young rats, Group Ic (weight category A) showing the maximum depletion (21.62 %), hepatomegaly and splenomegaly were frequent outcomes of parasitic infection and maximum change (50 %) was recorded in dual-infected pregnant rats (Group IId) expressed as SSI of the infected rat. The abnormal condition factor and organosomatic indices indicate perturbations in the biological systems at the organismal level. Thus, the information generated through this piece of work is a warning of an incipient or impending problem.

Abstract
BACKGROUND Both antitubercular therapy (ATT) and antiretroviral therapy (ART) can cause drug induced liver injury (DILI) in tuberculosis (TB) and human immunodeficiency virus (HIV) coinfection. The aim of this research was to study ATT-induced liver function test (LFT) abnormalities in HIV-infected patients. METHODS HIV-infected patients diagnosed with TB were evaluated with baseline LFT and CD4 counts. ATT regimen was modified if baseline LFT was significantly abnormal. Patients on protease inhibitors were given rifabutin instead of rifampicin. In patients on nevirapine-based ART, efavirenz was substituted for nevirapine. In ART-naive patients, the timing of introduction of ART was according to CD4 cell counts. LFT were repeated fortnightly or as clinically indicated for 10 weeks. RESULTS We studied 100 patients with HIV ([M - 67, F - 23], mean age: 40.05 ± 10.75 years, mean CD4 cell count: 239.157 ± 228.49 cells/dL). Sixty-one patients were on ART prior to diagnosis of TB. Baseline LFT abnormalities (n = 40) were similar in ART and non-ART group (28/61 vs 12/39, p = 0.13). After starting ATT, derangement of LFT was observed in majority of patients (99/100). However, liver sparing ATT was required only in 15 patients. Bilirubin >2.5 mg/dL was seen only in 9 patients. Significant rise in transaminases was commoner in patients on concurrent ART and ATT (p = 0.044) and with baseline LFT abnormalities (p = 0.00016). There was no case of acute liver failure or mortality. CONCLUSION Mild LFT abnormalities are common in HIV-infected individuals on ATT. Concomitant use of ATT and ART and baseline LFT abnormalities increase the risk of significant DILI. However, with closer follow-up, serious liver injury can be prevented.

Abstract
ETHNOBOTANICAL RELEVANCE Medicinal plants are frequently used by Gaddi and Gujjar tribes of Kangra and Chamba districts of Himachal Pradesh, India to cure various ailments in humans and livestock. Therefore, extensive field work was conducted to document the traditional use of ethnomedicinal plants by these tribes. MATERIALS AND METHODS Direct interviews of 208 informants were conducted. The data generated through interviews was analysed using quantitative tools such as use-value (UV), factor informant consensus (Fic) and fidelity level (Fl). RESULTS A total of 73 plant species in 67 genera and 40 families were observed to be medicinal and used to cure 22 ailment categories. The highest number of ethnomedicinal plants was recorded from the family Asteraceae followed by Lamiaceae, Apiaceae, Acanthaceae, Caesalpiniaceae, Polygonaceae, Ranunculaceae, Rosaceae and Rutaceae. Leaves were the most frequently used plant part used to treat various ailments followed by whole plant and roots or rhizomes. Ajuga parviflora, Berberis lycium, Viola canescens, Vitex negundo and Zanthoxylum armatum were the most important medicinal plants used for treating human diseases, whereas Achyranthes bidentata, Aloe sp., Cassia fistula, Podophyllum hexandrum and Pogostemon benghalensis were the most important medicinal plants used for treating animal diseases as per use value. The important ailment categories classified on the basis of factor informant consensus were gastrointestinal and respiratory disorders. CONCLUSION The present study revealed that people of the study area are extensively using the ethnomedicinal plants to cure various ailments. Plants with high use value and fidelity level should be subjected to pharmacological investigation for scientific validation.

Abstract
Bacterial adhesion and subsequent biofilm formation on material surfaces represent a serious problem in society from both an economical and health perspective. Surface coating approaches to prevent bacterial adhesion and biofilm formation are of increased importance due to the increasing prevalence of antibiotic resistant bacterial strains. Effective antimicrobial surface coatings can be based on an anti-adhesive principle that prevents bacteria to adhere, or on bactericidal strategies, killing organisms either before or after contact is made with the surface. Many strategies, however, implement a multifunctional approach that incorporates both of these mechanisms. For anti-adhesive strategies, the use of polymer chains, or hydrogels is preferred, although recently a new class of super-hydrophobic surfaces has been described which demonstrate improved anti-adhesive activity. In addition, bacterial killing can be achieved using antimicrobial peptides, antibiotics, chitosan or enzymes directly bound, tethered through spacer-molecules or encased in biodegradable matrices, nanoparticles and quaternary ammonium compounds. Notwithstanding the ubiquitous nature of the problem of microbial colonization of material surfaces, this review focuses on the recent developments in antimicrobial surface coatings with respect to biomaterial implants and devices. In this biomedical arena, to rank the different coating strategies in order of increasing efficacy is impossible, since this depends on the clinical application aimed for and whether expectations are short- or long term. Considering that the era of antibiotics to control infectious biofilms will eventually come to an end, the future for biofilm control on biomaterial implants and devices is likely with surface-associated modifications that are non-antibiotic related.

Abstract
Background: Type 2 diabetes mellitus is a multisystem disorder that is associated with number of complications. Patient's awareness and practices are crucial components in reducing the burden of diseases and its complications. Aim: To assess patient's knowledge about their disease and its complications, practices, treatment seeking behavior and average expenditure incurred by its management. Subjects and Methods: A community based cross-sectional study was conducted in rural and urban slum areas of Delhi selecting a total of 98 diabetic patients diagnosed during the two community surveys and interviewed using pretested and predesigned questionnaire. Data were analyzed using SPSS software, version 17 (Chicago II, USA). Chi-square, fisher or Mann–Whitney tests were used for test of significance and considered statistically significant at P < 0.05. Results: Of 98 participants, 31.6% (31/98) were from urban slum area, and 68.4% (67/98) were from the rural area. In both urban and rural areas, majority were Hindu, married, literate and unemployed. Significantly less subjects (61.3%, 19/31) of urban slum area than of rural area (85.1%, 57/67) could name at least one complication of DM (P < 0.01, odds ratio [OR] =3.6, 95% confidence interval [CI] =1.3–9.6). Majority of participants in both urban slum and rural area have knowledge about at least one component of management but significantly lesser in urban (83.9%, 26/31) than rural area (97.0%, 65/67) were reported (P = 0.02, OR = 6.2, 95% CI = 1.1–34.2). Significantly more subjects (29.0%, 9/31) in urban slum area than rural areas (7.5%, 5/67) reported that they were not taking any treatment for DM (P < 0.01, OR = 0.2, 95% CI = 0.1–0.6). In urban area, 32.2% (10/31) patients told that it is a burden on their family while in rural area 44.7% (30/67) of the patients told that they have to squeeze money from the family expenditure to afford drugs. Conclusion: Patients need to be made aware of the asymptomatic phase of DM and its long term complications. At the same time, efforts should be made to sensitize them about the importance of taking regular treatment and management.

Abstract
In the present study a simple, accurate, precise, economical and specific UV-spectrophotometric method for estimation of besifloxacin in bulk and in different pharmaceutical formulation has been developed. The drug shows maximum λmax289 nm in distilled water, simulated tears and phosphate buffer saline. The linearity range of developed methods were in the range of 3-30 μg/ml of drug with a correlation coefficient (r2) 0.9992, 0.9989 and 0.9984 with respect to distilled water, simulated tears and phosphate buffer saline, respectively. Reproducibility by repeating methods as %RSD were found to be less than 2%. The limit of detection in different media was found to be 0.62, 0.72 and 0.88 μg/ml, respectively. The limit of quantification was found to be 1.88, 2.10, 2.60 μg/ml, respectively. The proposed method was validated statically according to International Conference on Harmonization guidelines with respect to specificity, linearity, range, accuracy, precision and robustness. The proposed methods of validation were found to be accurate and highly specific for the estimation of besifloxacin in different pharmaceutical formulations.

Abstract
BACKGROUND AND PURPOSE Posterior reversible encephalopathy syndrome is associated with eclampsia. We assessed the distribution and nature of typical and atypical cranial MR imaging findings in these patients and their correlation with clinical and laboratory data and predictors of outcome. MATERIALS AND METHODS Forty-five clinically confirmed cases of eclampsia were included in this prospective observational study. Subjects with hemolysis, elevated liver enzymes, and low platelets syndrome (n = 9) and pre-existing neurologic conditions (1 with cerebral solitary cysticercus granuloma) were excluded. Patients underwent blood investigations and cranial MR imaging. RESULTS Twenty-seven patients had abnormal while 8 had normal MR imaging findings. Involvement of brain regions was as follows: frontal, 88.89%; temporal, 44.44%; parietal, 100%; occipital, 100%; deep gray matter, 29.63%; cerebellum, 22.22%; brain stem, 14.81%. Cytotoxic edema was present in 33.33% of cases; 66.67% of patients had mild posterior reversible encephalopathy syndrome; 25.92% had moderate posterior reversible encephalopathy syndrome; and 7.41% had severe posterior reversible encephalopathy syndrome. Abnormal neuroimaging findings were significantly associated with altered sensorium; visual disturbances; status epilepticus; and elevated serum creatinine, uric acid, and lactate dehydrogenase (P=.006, P=.018, P=.015, P=.019, P=.003, and P=.001, respectively). Serum creatinine, uric acid, and lactate dehydrogenase values and the presence of moderate or severe posterior reversible encephalopathy syndrome were significantly associated with mortality (P<.001, P<.001, P=.009, and P=.027, respectively). CONCLUSIONS Neuroimaging in eclampsia demonstrates a higher incidence of atypical distributions and cytotoxic edema than previously thought. Altered sensorium; visual disturbances; status epilepticus; and elevated serum uric acid, lactate dehydrogenase, and creatinine are associated with abnormal neuroimaging findings. Higher serum creatinine, uric acid, and lactate dehydrogenase levels and moderate and severe forms of posterior reversible encephalopathy syndrome are possible predictors of poor outcome.

Abstract
Objective: With technological evolution, use of power point presentation has been increased tremendously for classroom teachings in medical education. There is dearth of information that whether this technology is really liked by the students in anatomy or not. Therefore present study was conducted to assess which methodology of teaching anatomy was preferred by students: traditional (chalk & black-board), computer assisted or both when combined. Methods: A questionnaire based study was conducted that involved 250 1st year MBBS students. Students were asked to fill semi structured questionnaire that contained closed and open ended questions regarding teaching methodology. Results & Conclusion: 70.37% students favored combination of power point presentations along with traditional method, 25.93% preferred chalk and blackboard method and only 3.7% students opined that power point presentations should be the sole method of teaching. Therefore the study concludes that traditional method of lecture delivery in anatomy should be carefully amalgamated with power point presentations to meet the aspirations of students and to combat the limitations of chalk and board method.

Abstract
The strength of granular sludge is essential for the mechanical stability of the granules. Inorganic precipitants form a major factor influencing the strength of the granules. To check the possibility of apatite accumulation in anammox granules, and study its contribution to the mechanical strength of granules, anammox granular sludge was collected from Dokhaven municipal wastewater treatment plant, the Netherlands. Mineral precipitation inside the granules was visualized by micro-computed tomography, and apatite was identified by electron probe microanalysis and X-ray powder diffraction. The mechanical strength of anammox granules was measured by a low load compression tester. The contribution of apatite to the mechanical strength was evaluated by the generalized Maxwell model. Ca-PO4 minerals are reported to accumulate in anammox granules. A transformation of Ca-PO4 happens, and apatite is the final stable form. The accumulation of apatite increases the mechanical strength of anammox granules. A fast method to monitor and evaluate the accumulation of minerals in anammox granules was proposed.

Abstract
BACKGROUND Serological markers such as anti-neutrophil cytoplasmic antibody (ANCA) and anti-Saccharomyces cerevisiae antibody (ASCA) may be associated with pouchitis after ileal pouch-anal anastomosis (IPAA). AIM To perform a systematic review with meta-analysis of studies evaluating the association of ANCA and ASCA status with risk of acute and chronic pouchitis after IPAA. METHODS We searched multiple databases (upto September 2012) for studies reporting ANCA and/or ASCA status along with risk of acute or chronic pouchitis after IPAA in adults with ulcerative colitis (UC). We abstracted odds ratio (OR) or raw data from the individual studies to calculate summary OR estimates with 95% CIs using random-effects model. RESULTS Eight studies reporting 184 cases of acute pouchitis and six studies reporting 151 cases of chronic pouchitis were included. The odds of chronic pouchitis were 76% higher in ANCA-positive patients than ANCA-negative (six studies; OR: 1.76; 95% CI: 1.19-2.61; P < 0.01). ASCA-positivity was not associated with the risk of chronic pouchitis (three studies; OR: 0.89; 95% CI: 0.49-1.59; P = 0.68). Neither ANCA (eight studies; OR: 1.54; 95% CI: 0.79-3.02; P = 0.21) nor ASCA-positivity (two studies; OR: 1.28; 95% CI: 0.25-6.54; P = 0.77) were associated with the risk of acute pouchitis. CONCLUSIONS The risk of chronic pouchitis after IPAA is higher in ANCA-positive patients, but the risk of acute pouchitis is unaffected by ANCA status. ASCA status was not associated with the risk of acute or chronic pouchitis. This information may be used to counsel UC patients regarding their risk of pouchitis after IPAA.
