Abstract
BACKGROUND In-office three-dimensional (3D) printers and metal sleeveless surgical guides are becoming a major trend recently. However, metal sleeve-free designs are reported to be more prone to distortion which might lead to variation in the inner diameter of the drill hole and cause deviation and inaccuracy in the placement of the implant. Carbon fiber nanoparticles are reported to improve the properties of 3D printing resin material in industrial application. AIM The purpose of the study is to evaluate and compare the wear resistance of 3D-printed implant guides with metal sleeve, sleeve-free, and reinforced sleeve-free resin to the guide drill. MATERIALS AND METHODS A total of 66 samples with 22 samples in each group. Three groups including 3D-printed surgical guide with metal sleeve (Group A), without metal sleeve (Group B), an carbon fiber reinforced without metal sleeve (Group C) were included in the study. All samples were evaluated before sequential drilling and after sequential drilling using Vision Measuring Machine. The data were tabulated and statistically evaluated. RESULTS The data obtained were statistically analyzed with one-way analysis of variance and posthoc test. The data obtained for wear observed in the samples showed that the wear was highest in Group B with a mean of 0.5036 ± 0.1118 and the least was observed in Group A with a mean of 0.0228 ± 0.0154 and Group C was almost similar to Group A with mean of 0.0710 ± 0.0381. The results showed there was a significant difference between Group B with Group A and C, respectively (P < 0.05). The results showed that there was no significant difference regarding the wear observed between Groups A and C (P > 0.05). CONCLUSION The wear observed in the guide with a metal sleeve and carbon fiber reinforced without a metal sleeve was almost similar. The carbon fiber-reinforced guide showed better tolerance to guide drill equivalent to metal sleeve. Thus, carbon fiber nanoparticles reinforced in 3D printing resin have shown improved strength and can be used as a good replacement for a metal sleeve for an accurate placement of the implant.

Abstract
Quorum sensing (QS) is a molecular cell-cell communication utilized by several bacteria and some fungi. It involves cell density dependent gene expression that includes extra polymeric substance production, sporulation, antibiotic production, motility, competence, symbiosis and conjugation. These expressions were carried out by different signaling molecules like acyl homo-serine lactone (AHL) and auto-inducing peptides (AIPs) which was effluxed by gram negative and gram positive bacteria. Pathogenic bacteria and biofilms often exhibit high resistance to antibiotics, attributed to the presence of antibiotic efflux pumps, reduced membrane permeability, and enzymes that deactivate quorum sensing (QS) inhibitors. To counteract virulence and multi-drug resistance (MDR), novel strategies such as employing quorum sensing (QS) inhibitors and quorum quenchers are employed. It targets signaling molecules with synthesis and prevents the signal from binding to receptors. In this present review, the mechanisms of QS along with inhibitors from different sources are described. These strategies potentially interfere with QS and it can be applied in different fields, mainly in hospitals and marine environments where the pathogenic infections and biofilm formation are highly involved.

Abstract
Globally, the prevalence and pollution of pharmaceutical drugs in aquatic environments have been steadily increasing. This study sought to evaluate the effects of 14 days of exposure to environmental-relevant doses (ibuprofen 0.5, 5, and 50 µg/L, and carbamazepine 0.005, 1, and 10 µg/L) of the nonsteroidal anti-inflammatory drugs ibuprofen and carbamazepine in the freshwater fish Oreochromis mossambicus. The results showed a significant (P < 0.05) decrease in O. mossambicus superoxide dismutase, catalase, biotransformation enzymes, glutathione-s-transferase, glutathione peroxidase, oxidative stress lipid peroxidation, protein carbonyl activity, cellular damage metallothionine, reduced glutathione, immunological activities, and respiratory burst activity. Consequently, the acquired data revealed that O. mossambicus treated with ibuprofen and carbamazepine shows more significant alterations in metabolic depression, biochemical parameters, and oxidative stress. In addition, increased neurotoxic effects were observed in ibuprofen and carbamazepine treated O. mossambicus.

Abstract
Aim Antibiotics treat various diseases by targeting microorganisms by killing them or reducing their multiplication rate. New Delhi Metallo-beta-lactamase-1 (NDM-1) is produced by bacteria possessing the resistance gene blaNDM-1, the enzyme that makes bacteria resistant to beta-lactams. Bacteriophages, especially Lactococcus, have shown their ability to break down lactams. Hence, the current study computationally evaluated the binding potential of Lactococcus bacteriophages with NDM using Molecular docking and dynamics. Methods Modelling of NDM I-TASSER for Main tail protein gp19 OS=Lactococcus phage LL-H or Lactobacillus delbrueckii subsp. lactis after downloading from UNIPROT ID- Q38344. Cluspro tool helps in Understanding cellular function and organization with protein-protein interactions. MD simulations(19) typically compute atom movements over time. Simulations were used to predict the ligand binding status in the physiological environment. Results The best binding affinity score was found -1040.6 Kcal/mol compared to other docking scores. MD simulations show in RMSD values for target remains within 1.0 Angstrom, which is acceptable. The ligand-protein fit to receptor protein RMSD values of 2.752 fluctuates within 1.5 Angstrom after equilibration. Conclusions Lactococcus bacteriophages showed a strong affinity to the NDM. Hence, this hypothesis, supported by evidence from a computational approach, will solve this life-threatening superbug problem.

Abstract
BACKGROUND AND OBJECTIVES Epidermal growth factor receptor (EGFR) mutation analysis has become an important part of the initial workup of non-squamous non-small cell lung cancer (NS-NSCLC) patients. This study is attempted as South Indians population is comprised of ethnic groups with diverse genetic makeup and only very limited data on EGFR mutation is available from south India. A detailed understanding of EGFR mutation profile will help in better planning of treatment strategies and resource allocation. METHODS A retrospective analysis of EGFR mutation frequency in 350 patients diagnosed with adenocarcinoma of lung and its association with pathological characteristics was done. RESULTS Out of 350 cases of pulmonary adenocarcinoma, within an age group ranging from 30 to 86 years. EGFR mutations were identified in 34.8% (n = 122) cases, out of which 35.24% (n = 43) were in non-smoker females (P = 0.001). Of the 14 cases with resistant type of EGFR mutations, nine were in smoker males and the remaining five in non-smoker females. INTERPRETATION AND CONCLUSION Overall EGFR mutation frequency observed in our study was similar to other Indian studies. However, in our study, we observed that mutation in exon 21 was less frequent compared to other studies. A similar slightly increased frequency of rare mutations and double mutations were observed in our study. A detailed study of the molecular epidemiology of lung cancer and its association with different geographical zones of India is needed. This understanding will help in better planning of treatment strategies and resource allocation.

Abstract
In this study, the potential effects of 30-day exposure to environmentally relevant concentrations of chlorothalonil (0, 5, 10, and 20 μg L-l) were tested in the blood of the economically important olive flounder, Paralichthys olivaceus, using biochemical endpoints. Significant decreases in the enzymatic activities of immunity markers, alternative complements, and lysozymes were detected in the fish exposed to 10 or 20 μg L-l of chlorothalonil at day 20 or 30. The total immunoglobulin content was lowered in response to 20 μg L-l chlorothalonil at day 10 and 20, even when later exposed to 5 μg L-l at day 30. Among the essential blood components, the cortisol level was increased in response to chlorothalonil throughout the study with a decrease in white blood cells, while no changes were observed in hemoglobin, red blood cells, total protein concentration, and glucose in all exposures. The enzymatic activities of the three hepatic toxicity markers, alanine transferases, aspartate transaminase, and alkaline phosphatase, increased by 10 and/or 20 μg L-l of chlorothalonil. Significant oxidative stress was induced by chlorothalonil in the fish exposed to 10 or 20 μg L-l of chlorothalonil, as revealed by increased malondialdehyde and fluctuating glutathione levels with increase in the enzymatic activities of antioxidant defense system, including catalase and superoxide dismutase, during exposure. Taken together, these results suggest that long-term exposure to environmentally relevant concentrations of chlorothalonil can affect susceptibility to pathogens through immunosuppression, hepatic toxicity, and oxidative stress in olive flounder. These results can contribute to the monitoring of aquatic environments and ecotoxicological research through the measurement of blood components against waterborne chlorothalonil.

Abstract
Background Accidental electrocution was more common in animals and death was mostly due to shock and cardiac arrest. Survival of animals or humans could be possible if victims receive immediate medical support. Case description A 3-year-old crossbred Jersey heifer was presented to the Emergency and Critical Care Medicine Referral Clinic of the Veterinary College and Research Institute, Orathanadu, with a history of accidental electrocution by broken high-tension overhead power transmission line during grazing in the paddy fields. The animal was dull and depressed, dark red, and some areas were charred in appearance on the dorsum and limbs. The animal showed difficulty walking due to the electrocution burn injury and was poorly responding to the surroundings. Clinical examination revealed subnormal temperature, polypnea, pale mucous membranes, ruminal atony, and arrhythmias on auscultation. Findings/treatment and outcome On point of care (PoC) hematology testing, leukocytosis, neutrophilia, and microcytosis were observed. PoC electrolyte analysis revealed hypocalcemia (ionized calcium 0.89 mmol/L), mild hypochloremia, and severe hypokalemia (2.81 mmol/L). PoC biochemistry revealed hypoglycemia (41 mg/dl). PoC elevated levels of serum cardiac troponin (0.33 ng/dl) indicated cardiac damage. Aspartate aminotransferase (1794 U/L), CK-MB (699 U/L) and LDH (6.7 U/L) were also elevated. On PoC urinalysis, proteinuria, myoglobinuria, and glucosuria were observed. Evident clinical recovery, wound healing, and improvement in animal activities were observed. Conclusion High-voltage electrocution injury is a serious type of accident with the potential risk of multi-organ damage and death. Early diagnosis of electrocution and immediate management enhances the expectancy of complete recovery.

Abstract
In this paper, a self-adaptive load balancing technique is proposed using live migration of heterogeneous virtual machines (VM) in a Hyper-V based cloud environment. A cloud supported plugin as a management activity within the infrastructure as a service strategy. It is proposed to assist the load balancing process in such a way so that all hypervisors are almost equally loaded once the overload status gets triggered. In the cloud computing environment, load balancing plays a major role if the large number of events triggered has a high impact on the performance of the system. The efficiency of cloud computing is based on the efficient load balancing having a self-adjustable technique using live migration of VMs across clusters of nodes. The proposed load balancing model is efficient in performance improvement by efficient resource utilization and also it helps to avoid the situation occurrence of server hanging by the cause of server overload within the infrastructure of multiple Microsoft Hyper-V hypervisors environment.

Abstract
Embryos from the marine medaka fish Oryzias javanicus were treated with eight concentrations of benzo[a]pyrene (BaP) (0.001, 0.01, 0.1, 1, 2, 5, 10, or 20 μg L--1) after they had been fertilized. Significant mortality and hatching delays were detected in embryos that had been exposed to 10 and 20 μg L-1 BaP for 4 weeks. The mortality rate after hatching was higher in the medaka that had been previously exposed to > 2 μg L-1 BaP. Significant elevations in intracellular reactive oxygen species and malondialdehyde contents were measured and the mRNA expressions of the antioxidant defense system genes (gst, sod, cat, and gpx) increased in the embryos exposed to 10 and 20 μg L-1 BaP for 1 week. The hsp70, ahr, and cyp1a transcriptional responses were also significantly upregulated in the exposed groups after 1 week. The alterations to the in vivo parameters and molecular components suggested that waterborne BaP had a toxic effect on marine medaka embryos. Finally, fin defects, spinal curvature, and cardiac edema were highly induced when the embryos were exposed to > 5 μg L-1 BaP.

Abstract
In this study, potential immunological and hematological effects of different concentrations (0, 1, 10, and 50 μg L-l) of waterborne zinc pyrithione (ZnPT) were studied in the blood of the olive flounder Paralichthys olivaceus over 30 days. Reduced alternative complement activity (ACH50) and lysozyme activity were measured in fish exposed to 10 and/or 50 μg L-l of ZnPT for 20 days. Decreased levels of total Ig were also observed in response to 10 and/or 50 μg L-l ZnPT during the exposure period. Levels of cortisol, a marker of stress, were significantly increased by 10 and 50 μg L-l ZnPT from day 10, and by 1 μg L-l exposure on day 30. The levels of red blood cells (RBCs) and white blood cells (WBCs) decreased following exposure to 10 and/or 50 μg L-l ZnPT, while no significant change was observed in hemoglobin level. Concentrations of total protein and albumin were significantly reduced with 50 μg L-l ZnPT at day 20. Alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase activities were significantly increased following exposure to 10 and/or 50 μg L-l ZnPT. Lipid peroxidation was induced by ZnPT, and higher concentrations (10 and 50 μg L-l) significantly increased intracellular malondialdehyde levels during exposure. Regarding the subsequent antioxidant response, intracellular glutathione levels increased significantly in response to 10 and 50 μg L-l ZnPT on days 20 and 30. Similarly, catalase and superoxide dismutase activity was significantly increased in response to 10 and 50 μg L-l ZnPT after day 10. Taken together, changes in the studied parameters suggested the immunotoxicity of ZnPT, with modulations observed in hematological homeostasis and oxidative stress induction in the blood of olive flounder.

Abstract
Immunotoxic effects of manganese (Mn) were investigated in the blood of the economically important marine fish, red seabream (Pagrus major) and black rockfish (Sebastes schlegelii) when exposed to different concentrations of Mn (0, 0.5, 1, and 2 mg L-1) for 14 days. During exposure, the levels of alternative complement activity in both fish were significantly lowered at 2 mg L-1 of Mn of exposure. Lysozyme activity was significantly decreased in black rockfish in all concentrations of Mn after 14 days, while in red seabream, the decrease was significant with concentrations of 1 and 2 mg L-1 of Mn after 7 and 14 days of exposure. A significantly low level was observed only in the 2 mg L-1-exposed red seabream on day 14 of exposure. The concentrations of hemoglobin, red blood cells, white blood cells, and total serum proteins were significantly decreased in both fish under exposure to 1 and 2 mg L-1 of Mn, while cortisol, alanine transferase, aspartate transaminase, and alkaline phosphatase levels were significantly increased compared to the levels of control groups. No significant change was found in serum glucose and albumin except in red seabream exposed to 2 mg L-1 of Mn for 14 days. The responses of the antioxidant defense system were significantly induced in both fish after exposure to 1 and 2 mg L-1 of Mn on day 7 and 14 of exposure. Taken together, alterations of these parameters suggest the immunotoxicity of waterborne Mn produced by the modulation of hematological components and the induction of oxidative stress in the blood of these marine fish.

Abstract
Low concentrations of nonylphenol (NP) in aquatic environment can induce drastic effects on the endocrine system in animals. In this study, we examined the modulatory effects of NP on reproductive and physiological parameters in juveniles of the red seabream and black rockfish following waterborne NP exposure (0, 1, 10, and 50 μg L-1) for 60 days. In red seabream exposed to 50 μg L-1 NP, plasma levels of 17β-estradiol (E2) and 11-ketotestosterone (11-KT) were significantly lower at 30 and 60 days, while E2 levels were slightly higher in 10 μg L-1-exposed individuals at day 30. Similarly, significantly lower levels of E2 and 11-KT were observed in 10 and 50 μg L-1-exposed black rockfish at 60 days, whereas the E2 level was higher in 1 μg L-1-exposed individuals at day 30. After exposure to NP, plasma and mRNA levels of vitellogenin (VTG) were significantly higher in both species at 30 and 60 days, similar to the inducible effects from synthetic estrogen. Plasma cortisol levels were significantly elevated by relatively higher concentrations of NP (10 and 50 μg L-1) at 30 and 60 days. Finally, 60 days of exposure of 50 μg L-1 NP significantly decreased the gonadosomatic index (GSI) and increased the hepatosomatic index (HSI) in both species. The results obtained from this study provide an evidence of the endocrine disrupting potential of waterborne NP on early stages of economically important marine fish. The NP-triggered endocrine modulation can induce effects on the development of reproductive and metabolic organs in fish species.

Abstract
Tributyltin (TBT) is as an antifouling organotin compound used in boat paints. Although organotin-based antifouling agents have been banned on a global scale, the mode of action of TBT has been studied in numerous aquatic species because of its toxicity, persistence, bioaccumulation potential, and endocrine-disrupting characteristics. In this study, we conducted 96-h acute toxicity tests wherein we exposed juvenile and adult marine mysids to waterborne TBT. Over 4 weeks of exposure, mortality was dose-dependently increased in juveniles and adult mysids. To test sublethal effects of TBT on juvenile development, newborn juvenile mysids were exposed to 1, 5, or 10 ng L-1 TBT for 4 weeks. Subsequently, we measured morphological growth parameters and quantified the hormone ecdysterone (20-hydroxyecdysone: 20E), which controls molting in mysids. The lengths of the whole body, antennal scale, exopod, endopod, and telson were significantly smaller in the 5 and/or 10 ng L-1 TBT-exposed juvenile mysids than in control and DMSO-exposed groups. Levels of 20E were significantly lower at 5 and 10 ng L-1 TBT exposures. Additionally, the number of newly hatched juveniles was significantly lower from females previously exposed to 10 ng L-1 TBT. Our results indicate sublethal concentrations of TBT have inhibitory effects on the survival, growth, and production of juveniles. The lower 20E levels could be strongly associated with TBT-triggered inhibition.

Abstract
Zinc oxide nanoparticles (ZnONPs) exhibit abundant biomedical applications. Anisotropic ZnONPs with a defined shape and size were synthesized using Bacillus megaterium (NCIM 2326) cell free extract as a bio-reductant. The study investigated the multidimensional effect of ZnONPs on Helicobacter pylori strains and assessed its biosafety in normal human mesenchymal stem cells (hMSc). The highly stable ZnONPs were produced using B. megaterium and Zinc nitrate as a precursor. The phase of ZnONPs formation and structural characterization were performed by UV- visible (UV-Vis), Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) and Field Emission Scanning electron microscopy (FESEM) analysis. Furthermore, the ZnONPs exhibited higher biocompatibility against human mesenchymal stem cells (hMSC) and proved to be potentially safe in mammalian cells. Corroborating the current investigation, we described the anti-H. Pylori dosage of ZnONPs was safe to hMSC and could efficiently use as nano-antibiotic.

Abstract
Probiotics are vital bacteria that colonize the intestine and modify its microflora with benefits for the host. Very few members of the Bacillus group are recognized as safe for use and hence only a few strains are available as commercial preparations for application in humans and animals. Acute and subacute studies in rats were conducted to establish safety of Bacillus clausii (B. clausii) UBBC07. In the acute toxicity study, the oral LD50 for B. clausii UBBC07 was found to be >5000 mg/kg (630 billion cfu/kg) body weight. The NOAEL for B. clausii UBBC07 was found to be 1000 (126 billion cfu) mg/kg body weight/day by oral route in the subacute toxicity study. There were no significant differences between control and treated groups in any of the endpoints assessed using an OECD443 or OECD407 protocol. B. clausii UBBC07 was found to be resistant to three antibiotics -clindamycin, erythromycin and chloramphenicol. Analysis of the whole genome sequence of B. clausii UBBC07 revealed that the antibiotic resistance genes are present in chromosomal DNA which is intrinsic and not transferable. Toxin genes were also found to be absent. These results suggest consumption of B. clausii UBBC07 is safe for humans.

Abstract
INTRODUCTION Implant-supported prosthesis has high predictability and success and improves quality of life. This study aims at assessing awareness among the patients regarding implant-supported prosthesis. MATERIALS AND METHODS A cross-sectional study was conducted among 391 study participants. A structured questionnaire was distributed to assess implant-related awareness among the study participants. The questionnaires were analyzed for the responses. RESULTS Among the 391 respondents, 37.5% of the respondents reported having moderate knowledge regarding the tooth replacement options. Nearly 50% considered implants as a viable treatment option. The majority of them enlisted the dentist as the major source of information regarding implants, and media had a share of about 7.03% only. High cost was a major barrier in selecting implants as a treatment option. CONCLUSION This survey showed that awareness among people was low regarding the dental implants. Efforts need to be directed to increase the awareness levels by utilizing media as a tool to achieve the target. CLINICAL SIGNIFICANCE A patient who is aware of the advantages of the implant-supported dentures will make an informed decision for better functional stability and retention of the denture, especially in the mandibular arch.

Abstract
Aim: To describe treatment outcomes and complications of selective intra-arterial chemotherapy (IAC) for retinoblastoma (RB) in Indian eyes. Materials and Methods: Single center, retrospective interventional case series of 6 eyes with RB who underwent IAC using Melphalan (3 mg/5 mg/7.5 mg) and topetecan (1 mg) (n = 4) or melphalan (3 mg/5 mg/7.5 mg) alone (n = 2) between December 2013 and June 2014. In all, 17 IAC procedures were performed using selective ophthalmic artery cannulation. Treatment outcomes were evaluated in terms of tumor control, vitreous and subretinal seeds control and globe salvage rates. Results: IAC was employed as primary (n = 1) or secondary (n = 5) modality of treatment. Each eye received mean 3 IAC sessions (median: 3; range: 1-4 sessions). Eyes were classified according to international classification of RB as Group B (n = 1), C (n = 1), D (n = 2) and E (n = 2). Following IAC, complete regression of the main tumor was seen in 3 cases (50%), partial regression in 2 (33%), while 1 case (15%) showed no response. Of 4 eyes with subretinal seeds, 1 (25%) eye had complete regression while 3 (75%) eyes had partial regression. Of 5 eyes with vitreous seeds, 2 (40%) eyes had complete regression while 3 (60%) eyes had a partial response. Globe salvage was achieved in 5 of 6 eyes (83%). Diffuse choroidal atrophy and vitreous hemorrhage were observed in 1 (17%) eye, each. No hematologic toxicity or cerebro-vascular events were observed. Mean follow-up period was 5.5 months (median: 6 months, range: 1-6 months). Conclusion: IAC is an effective therapy for globe preservation in eyes with RB. Larger studies with longer follow-up are required to validate these results.

Abstract
AIM OF THE STUDY Ichnocarpus frutescens (L.) R.Br. (Apocynaceae) is used by the traditional healers in India to treat diabetes and hyperlipidemia.This work aims to study the antiobesity effect of the active sub-fraction obtained from the leaves of this plant using in vitro and in vivo models. METHODOLOGY Active sub-fraction (Sfr3) isolated by column chromatography was analyzed using Gas chromatography and mass spectrometry. Adipogenesis and apoptosis were detected by oil red O and Hoechst-33342 staining, respectively, in 3T3-L1 adipocytes. Expression of specific marker genes involved in lipid metabolism was detected by Reverse Transcriptase Polymerase Chain Reaction in 3T3-L1 adipocytes and adipose tissues of C57 BL/6J mice, fed with high fat diet (HFD) and treated with Sfr3 and fenofibrate for 45 days. RESULTS The treatment with Sfr3 decreased lipid accumulation and caused apoptosis in adipocytes. In the HFD induced obese animals, serum and liver lipid levels were decreased and a significant decrease in body weight gain was observed dose dependently in 45 days treatment. Histopathological examination showed decrease in adipose mass and liver lipid accumulation. The effect of Sfr3 on the marker genes of adipocytes was significantly regulated at the treated doses both in vitro and in vivo. CONCLUSION Sfr3 of Ichnocarpus frutescens is effective in the management of obesity through adipocyte apoptosis.

Abstract
The fate and effect of nanomaterials in the environment has raised concern about their environmental risk to aquatic organisms. Silica nanoparticles (SiO2-NPs) find its uses in various fields and are inevitably released into the environment. However, the ecotoxicological effects of SiO2-NPs on the freshwater fish remain poorly understood. The aim of this study was to evaluate the effect of different concentrations (1, 5 and 25mgL(-1)) of SiO2-NPs on certain hematological, ionoregulatory and enzymological profiles of a freshwater teleost fish Labeo rohita. Hematological parameters such as hemoglobin (Hb), hematocrit (Hct), red blood cells (RBC), white blood cells (WBC), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) values were altered in SiO2-NPs treated groups. Likewise, plasma electrolytes such as plasma sodium (Na(+)), potassium (K(+)) and chloride (Cl(-)) levels and Na(+)/K(+) ATPase activity in gill of SiO2-NPs treated groups were altered in all concentrations throughout the study period (96h). The alterations of these parameters were found to be dependent on dose and exposure period. The results of the present study indicate that the alterations of these parameters may relate to physiological stress system to SiO2-NPs toxicity and also demonstrate that manufactured metal oxide NPs in aquatic environment may affect the health condition of the aquatic organisms.

Abstract
PURPOSE This study aimed to compare the viscoelastic properties and antimicrobial activity of a soft liner with and without silver zeolite for a period of 4 weeks. MATERIALS AND METHODS Thirty edentulous patients wearing complete dental prostheses were selected. A uniform space was created in the intaglio surface of their maxillary prosthesis, and a soft liner without silver zeolite (control material: S) was applied. After 28 days, the soft liner was replaced with new soft liner containing silver zeolite (test material: SZ) and worn for another period of 28 days. Viscoelastic analysis was conducted on the prostheses using S and SZ materials for newly formed samples (T0) and on samples collected after the 28-day period (T28). Culture tests were performed on both materials at T28. Statistical analysis was done using Student independent t test. RESULTS The decrease in elasticity from T0 to T28 was found to be 76.49% and 79.11% and the decrease in viscosity was 76.49% and 80.3% for the S and SZ materials, respectively. Hence, the difference was not significant. The mean colony-forming units (CFUs) of Candida albicans and gram-negative bacteria in the S material at T28 days was 3,150 ± 1,251, whereas that of the SZ material was 1,084 ± 662. There was a statistically significant difference in the mean CFUs between the two groups (P < .05). CONCLUSIONS The addition of silver zeolite to the soft liner improved the antimicrobial activity while not affecting significantly its viscoelastic properties.

Abstract
The propagation of an electromagnetic wave in a uniaxial ferromagnetic nanowire under the spin transfer torque effect is widely investigated in the soliton frame. The magnetization dynamics of the ferromagnetic nanowire is governed by the Landau-Lifshitz-Gilbert (LLG) equation coupled to the Maxwell equation for the electromagnetic wave propagation. A nonuniform multiscale analysis is invoked for the coupled LLG-Maxwell equations and obtains the extended derivative nonlinear Schrödinger (DNLS) equation for the magnetization and external magnetic field. The effect of electric current is explored by constructing multisoliton solutions to the extended DNLS equation and the possibility of the soliton collision is exploited using the Hirota bilinearization procedure.

Abstract
Immunoglobulin G4-related disease (IgG4-RD) is an emerging clinicopathological entity. Renal involvement is dominated by tubulointerstitial nephritis (TIN) with IgG4-positive plasma cells and fibrosis. IgG4-RD commonly affects middle-aged to elderly men with accompanying extra-renal lesions such as sialadenitis, lymphadenopathy, or type 1 autoimmune pancreatitis, all of which respond favorably to corticosteroid therapy. The disease burden of IgG4-related kidney disease (IgG4-RKD) in India remains largely underestimated. We report a case of IgG4-RKD manifesting as TIN associated with interstitial pulmonary disease, illustrating typical clinico-pathologic, serologic, immuno-histochemical, and ultrastructural features of this condition. In view of potential amelioration of renal dysfunction with appropriate therapy, the need for awareness of this condition and early diagnosis is highlighted.

Abstract
In the present investigation, the toxicity of most commonly detected pharmaceuticals in the aquatic environment namely clofibric acid (CA) and diclofenac (DCF) was investigated in an Indian major carp Cirrhinus mrigala. Fingerlings of C. mrigala were exposed to different concentrations (1, 10 and 100μgL(-1)) of CA and DCF for a period of 96h (short term) and 35 days (long term). The toxic effects of CA and DCF on thyroid hormones (THs) such as thyroid stimulating hormone (TSH), thyroxine (T4) and triiodothyronine (T3) levels were evaluated. During the short and long-term exposure period TSH level was found to be decreased at all concentrations of CA (except at the end of 14(th) day in 1 and 10μgL(-l) and 21(st) day in 1μgL(-l)) whereas in DCF exposed fish TSH level was found to be increased when compared to control groups. T4 level was found to be decreased at 1 and 100μgL(-l) of CA exposure at the end of 96h. However, T4 level was decreased at all concentrations of CA and DCF during long-term (35 days) exposure period. Fish exposed to all concentrations of CA and DCF had lower level of T3 in both the treatments. These results suggest that both CA and DCF drugs induced significant changes (P<0.01 and P<0.05) on thyroid hormonal levels of C. mrigala. The alterations of these hormonal levels can be used as potential biomarkers in monitoring of pharmaceutical drugs in aquatic organisms.

Abstract
Tick-borne infectious diseases constitute an emerging problem in Veterinary Medicine. The study was undertaken to find out the ultrasonographic changes of liver and spleen in 101 positive cases of tick borne intracellular haemoparasitic diseases in dogs. Abdominal survey of ultrasonography revealed hypo echogenicity of liver, gall bladder distension, splenomegaly, hepato-splenomegaly and ascites in various tick born intracellular diseases viz. ehrlichiosis, babesiosis, anaplasmosis, hepatozoonosis and in mixed infection. Correlating these USG finding with other laboratory examination will be very much useful to spot the diseases condition and organ involvement in tick born intracellular diseases of dog.
