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
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.

Abstract
Extensive use of pharmaceuticals in human and veterinary medicine and aquaculture practices pose a serious threat to aquatic organisms. In the present investigation, Cirrhinus mrigala an Indian major carp was exposed to different concentrations of clofibric acid (CA) and diclofenac (DCF) and certain biochemical and ionoregulatory responses were assessed under short and long term exposures. During short-term (96h) exposure period, plasma glucose and sodium (Na(+)) levels were increased at all concentrations (1, 10 and 100μgL(-1)) of CA and DCF treated fish. Plasma protein and chloride (Cl(-)) levels were found to be decreased at all concentrations of CA and DCF exposed fish comparatively to control groups. Meanwhile an increase in plasma potassium (K(+)) level was noted in fish exposed to CA treatments alone and in DCF treatments it was decreased. In long-term exposure (35d), plasma Na(+) and Cl(-) levels were found to be significantly increased at all concentration of CA and DCF. However, a biphasic trend was observed in plasma glucose, protein and K(+) levels. In both the treatments, a significant (P<0.01 and P<0.05) changes were observed in all parameters measured in fish exposed to different concentrations of CA and DCF. The results of the present investigation indicate that both the drugs caused significant changes in biochemical and ionoregulatory responses of fish at all concentrations. The alterations of these parameters can be useful in monitoring of pharmaceutical residues present in aquatic environment.
