- Abstract
The study was carried out to evaluate the hepatoprotective activity of leaf and leaf callus extracts of Anisochilus carnosus (L) Wall. against alcohol induced toxicity using HepG2 cell line. Leaf explants were cultured on Murashige and Skoog solid medium supplemented with different growth regulators. Prior to the determination of hepatoprotective property leaf and leaf callus extracts were subjected to the toxic dose study. The degree of hepatoprotection of extracts was determined by measuring cell viability percentage by MTT assay. The preliminary phytochemical analysis of leaf and leaf callus was carried out by qualitative analysis. Maximum percentage of callus formation (98%) was obtained in MS medium fortified with 3 mg/l 2,4-D. HepG2 cells were pretreated with the different concentrations (below toxic dose) of leaf and leaf callus extracts for 72 hours followed by alcohol intoxication. Results revealed that ethanolic leaf extract pretreated HepG2 cells show 94% cell viability compared to the standard silymarin pretreated HepG2 cells which showed 81% cell viability. Leaf callus extracts also exhibited significant hepatoprotective activity where ethanolic callus extract pretreated HepG2 cells showed 86% viability after intoxication with alcohol. Results revealed that HepG2 cell viability percentage is dose dependent. Phytochemical studies revealed the presence of different secondary metabolites in leaf and leaf callus extracts. The bio-efficacy study confirms the presence of secondary metabolites of hepatoprotective nature in leaf and leaf callus of A. carnosus. more...

- Abstract
The traditional healers in Wayanad (Kerala), India possess rich aboriginal herbal medicinal knowledge (AHMK). This investigation has brought in to light many valuable therapeutic measures which were at the verge of extinction. Validation and documentation of some of such valuable in formation was hence done in order to conserve at least a part of this aboriginal ethno medicinal heritage. The study consists of three consecutive phases. In the first phase a methodology for the study including work plan was elucidated. A field level testing of the method was executed at a selected study site. In the second phase an extensive data collection cum field appraisal long three calendar years commences from July 2010 to July 2013 was conducted. In the final and third phase, validation and recording of the valid responses was done. A total of 60 species distributed in 56 genera belong to 38 families were identified being used in 67 recipes meant for 15 reproductive and urinary healthcare measures in Wayanad (Kerala), India. 31 herbs, 28 trees, 22 climbers and 16 shrubs were among the medicinal constituents. The therapeutic ingredients includes Fresh whole plants (12), dried whole plant (08), fresh root (2), dry root (29), fresh tuber (01), dried tuber (17), fresh bark (01), dried bark (02), fresh leaves (04) dried leaf (01), dried stem (01), dried petiole (01), pith powder (01), dried gum (2), fresh inflorescence (01), dried inflorescence (01), fresh flower (03), dried stamen (01), dried fruits (07), dried seeds (11), and seed oil (01). Validity stands maximum when FPVS was four and minimum when FPVS was two. Among the 67 medicinal recipes 59 has highest FPVS and the remaining 08 has mediocre FPVS. Many of the aboriginal herbal medicinal cultures (AHMC) and the associated therapeutic knowledge and practices still alive in the district are at the verge of extinction.

- Abstract
Developing traditional medicine in the field of hepatology and nephrology research is the key to pharmacology. This study demonstrates the mechanism of hepatoprotective and renal protective activity of Ficus dalhousiae Miq. (Moraceae) methanolic leaf extract on carbon tetrachloride induced hepatic and renal toxicity. Shade dried powder was subjected to shoxlet extraction with methanol and assessed for hepatoprotective and renal protective activities. Hepatotoxicity and renal toxicity were induced in rats by single oral dose of CCl4 diluted with olive oil (1:1 v/v; ml/kg body weight) after pretreatment of methanolic extract for seven days. Sixteen hrs after CCl4 administration, rats were sacrificed and biochemical markers like Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) estimated followed by the measurement of liver and kidney cytosolic antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), glutathione (GSH) and reactive oxygen species (ROS). The data were analysed by one way analysis of variance (ANOVA). The extract at the doses of 150 and mg/kg b.w. significantly reduces elevated levels of ALT, AST, ALP and LDH. The extracts also showed significant increase in the reduced level of SOD, CAT and GSH. The ROS activity also found down regulated. The activity of methanolic extracts were comparable with the standard Silymarin. These findings not only showed potential hepatoprotective and renal protective activities of Ficus dalhousiae but also manifested by restoring antioxidant enzymes. With this pilot study we can justify the medicinal importance of this plant. more...

- Abstract
Laplace decomposition methods are based on Laplace transform method and Adomian decomposition method or modified Adomian decomposition method. In this paper we show that the methods are applicable to the class of successive interval valued linear as well as nonlinear differential-difference equations with the differential order two and the difference order one involving a two variable function admitting Taylor series expansion. Two test problems are selected to illustrate the applicability of methods. In both the problems, when the difference parameter w = 0, the resulting differential equations have exact solution. The exact solution is used to compare approximate solutions obtained by Laplace decomposition methods. Numerical results show good convergence of approximate solutions. more...

- Abstract
A new class of molecular architecture made of five conjugated rings carrying terminal methyl or variable alkoxy (chain lengths of 4, 6, 8, or 16) substituted at para positions has been synthesized. Among the five rings, two rings are of cyanopyridones utilized as an electron deficient N-heterocycle along with blue luminescent motif, and the rest of them are phenylene motifs. All the compounds produced good yield and ATR-IR, NMR and Mass spectroscopy confirmed their structures. Further, the compounds were stable up to ≈200 °C and the degradation occurs at higher temperature as evident from the TGA analysis. The mesomorphic study reveals that compound is only having very long terminal n-hexadecyloxy substituents appeared in-layers liquid crystalline organization as confirmed by POM and variable temperature XRD analysis. Further, the compounds showed intense blue fluorescence in both solution as well as solid state and their fluorescence quantum yields are dependent on the length of alkoxy chains. Calculated HOMO/LUMO levels by cyclic voltammetry measurements revealed that the compounds are ambipolar in nature and cited as an ideal candidates for electroluminescent applications. more...

- Abstract
Aphanamixis polystachya (Wall.) Parker, vernacularly called “Amoora rohituka” is a medicinal plant belonging to the family of Meliaceae and appearing among Indian natural drugs used as remedy as an astringent and applied on swelling after a fall. In recent times anti carcinogenic ingredients are found from this plant. The search for safe therapeutic molecules suitable for long term use are most needed today to prevent the progression of free radical mediated diseases. Hence, the antioxidant activity of polar and non-polar solvent extracts of the leaf of Aphanamixis polystachya was evaluated in a series of in vitro assay involving free radicals and reactive oxygen species. The extract exhibited its scavenging effect in concentration dependent manner depending on the solvent extract on superoxide anion radicals, DPPH radical scavenging and property of metal chelating and reducing power. The extract has shown considerably good value for total reducing power, total phenolics, flavanoids and flavanol content. more...

- Abstract
Nervilia aragoana Gaud. (Orchidaceae) has long been used in the antidiabetic medicinal preparations of traditional healers of Wayanad (Kerala), but antidiabetic and regenerative potential of the plant remain unravelled. The aim of the present study was to investigate the recuperative and regenerative potential of alcoholic stem extract of Nervilia aragoana Gaud. on streptozotocin-nicotinamide induced type 2 diabetic models. Administration of 5mg/kg of plant extract, blood glucose levels of the NIDDM rats showed 65.91 and 76.58 % decrease in the blood glucose levels on 0 and day 30 days respectively. Damages caused to the kidney tissue were negligible or not seen. Serum urea and creatinine levels showed 65.00 % and 71.00% decrease on day 30. LPP levels of kidney and pancreas showed 76.47 % and 74.19% decrease respectively. These results demonstrate significant antidiabetic and regenerative potential of the Nervilia aragoana Gaud. justifying the use of plant in the indigenous system of medicine. Isolation and characterisation of the compound(s) playing pivotal role in the cure would open new vistas in the therapy of type 2 diabetes. more...

- Abstract
The ever increasing resistance of pathogens to antibiotics as well as the undesirable side effects of certain antimicrobial agents has necessitated the discovery of novel natural products. The ethanolic extract of O. tenuiflorum was investigated against S. aureus isolate which is a major pathogen causing infective endocarditis. The total phenolic content in O. tenuiflorum was found to be 1289 μg gallic acid equivalent/g and HPLC profile revealed the presence of catechin, Caffeic acid and p-coumaric acid. The antibacterial profile of O. tenuiflorum against S. aureus isolate from infective endocarditis patients exhibited significant inhibition at the MIC of 50 μg/ml and the standard antibiotic Vancomycin showed inhibition at 40 ng/ml. Percent inhibition of viable growth was found to be >95% and the scanning electron micrographs (SEM) revealed the disruption of the membrane of S. aureus treated with O. tenuiflorum extract. The antimicrobial activity correlates with phenolic content of the extract. These results demonstrate the potency of O. tenuiflorum, could serve as a new source of antimicrobials with potential applications and related health benefits. more...

- Abstract
Ethanolic and water extracts from six species of Indian medicinal plants mainly distributed in the region of Western Ghats, India such as Morinda citrifolia (leaf), Garcinia indica (leaf), Garcinia cambogia (leaf), Salacia oblonga (leaf), Coccinium fenestratum (stem bark) and Calophyllum inophyllum (bark) were tested for their inhibitory activities against two prime enzymes of HIV which are HIV-1 protease (HIV-PR) and HIV-1 integrase (HIV-IN). The results revealed that the ethanolic and water extract of the bark extract of Calophyllum inophyllum exhibited potent anti-HIV-IN activity with IC50 values of 9.8 and 5.6 μg/ml, respectively. Whereas those for anti-HIV-1 PR effect were found to be 63.8 and 16.3 μg/ml, respectively. This result strongly supports the basis for the use of C. inophyllum for AIDS treatment by local traditional practitioners of Ayurveda and Unani system of Indian medicine and it is the first report on HIV-1 Protease and HIV-1 Integrase enzyme inhibition by this plant extract. more...

The paper is based on the research survey undertaken during 2007-2010. The availability of GL collections and its use pattern in the Recognised Research Centres of Visvesvaraya Technological University (VTU) have been analysed on the basis of the responses of the librarians and the personal observation of the situation in the libraries. A detailed attempt is also made to capture the responses of the users on the use pattern of GL in these Recognized Research Centres. Here, the users constitute the faculty members (340) engaged in supervising the research programmes, and the research scholars (930) who have registered with VTU for doctoral research. The extent of the use of the 6 types of conventional form of GL : theses, dissertations, institutional publications, trade literature, technical reports and proceedings of conferences, seminars and workshops has been studied on the basis of the feedback rendered by the faculty and researchers working in the 65 engineering colleges in Karnataka which are identified for conduct of research programmes. Further, the research systematically covers every aspect involved in building strong need based GL collections useful for research in engineering science and technology. The mode of procurement of GL to the libraries, habits of the faculty in visualizing the recent releases of GL and the trends in exploiting the GL collections available in the local and regional libraries have been depicted with adequate data using tables, diagrams and charts. The research suggests for the creation of databases of GL, resource sharing and development of digital repositories of theses and proceedings of conferences and seminars, for which increased demand is noticed from the user community. Paper encompasses in its purview the aspects related to use pattern of GL collections by research supervisors and the research scholars mainly for the purposes of teaching, research and extramural activities such as delivering special lectures, preparing conference papers and articles for scholarly journals. The study also captures the training needs of the working librarians and information scientists for building GL collections, comprehensively and systematically and also to facilitate access to GL in the network environment. The need of orientation and training of the user community, covering the faculty and researchers has also been projected expecting better access and use of GL collections in the Research Centres of the VTU.

- Abstract
Leucasin is one of the active antimicrobial principle of Leucas aspera. The effect of this compound and other antibacterial agents with known mechanisms of action upon the cytoplasmic membrane integrity of Staphylococcus aureus was investigated by comparing scanning electron microscopy (SEM) and potassium loss profiles from bacterial cell suspensions. The minimum inhibitory concentrations (MICs) of leucasin, novobiocin - the bacteriostatic antibiotic and penicillin G – the bactericidal antibiotic against S. aureus (ATCC 12600) were determined as 35 μg/ml, 55 ng/ml and 40 ng/ml respectively. The morphology of S. aureus was impaired, when treated with leucasin showing mucilaginous mass, which could lead to the impairment in cell division, as observed under SEM. When S. aureus were suspended in potassium free media containing 35 μg/ml leucasin, a 100 fold decrease in viability was observed after 12 h. Potassium loss assay revealed that S. aureus treated with 35 μg/ml leucasin lost 17% more potassium than untreated control populations whereas, cells treated with 40 ng/ml of penicillin G exhibited 9% increase in potassium loss and 55 ng/ml of novobiocin had no effect on potassium loss. This data may be attributed to either direct damage to the cytoplasmic membrane or indirect damage affected through autolysis/weakening of the cell wall and consequent osmotic lysis. more...

The resulting HA powders were characterized by X-ray diffraction, infra-red spectroscopy, thermogravimetry, and transmission electron microscopy, nitrogen adsorption and dynamic light scattering methods. Choosing reaction conditions in the 99 yield region of the CaO–P2O5–NH4OH–H2O phase-pure equilibrium system, nearly stoichiometric and nanostructured HA powders were prepared at room temperature in as little as 1 h. The minimum time to obtain phase-pure HA was 8 h from the conventional attrition mill. As-prepared powders were found to be highly agglomerated with a mass-weighted mean diameter of 2.6 µm in deionized water and average agglomeration number AAN as high as 4.5 × 106. Dispersion studies revealed that the appropriate use of dispersants could reduce the mass-weighted mean diameter and AAN. In the presence of sodium polyacrylate, the mass-weighted mean diameter and AAN were 217 nm and 1600, respectively. more...

- Abstract
The arithmetical theory of irrational numbers has been developed in three main forms, of which the first was given by Weierstrass in his Lectures on Analytical Functions, the second is that of Cantor and the third that due to Dedekind. Of these three theories, it has been shown that those of Cantor and Dedekind are fundamentally identical and it has been established that whereas the theory of Dedekind operates with the whole aggregate of rational numbers, the other operates with sequences selected out of that aggregate. We here propose to establish the fundamental identity of all the three theories of irrational number by establishing the same for the theories of Weierstrass and Cantor and to show that the entities used in the former definition are but particular types of the entities used in the latter. more...

It has been claimed that the economist of to-day has prevailed upon the Parliamentary mind and as a result " without interfering with, or abrogating, the essential elements of freedom in the policy of laissez faire and without assuming the awkward and dangerous responsibility for fixing prices and incomes, Parliament has interfered materially with the distribution of wealth, has done much to secure a better distribution and has done more probably in the present century to solve the problem of poverty than any previous generation or any other country has been able to do."* more...

Mitochondria are an autonomous organelle that plays a crucial role in the metabolic aspects of a cell. Cortical spreading depression (CSD) and fluctuations in the cerebral blood flow have for long been mechanisms underlying migraine. It is a neurovascular disorder with a unilateral manifestation of disturbing, throbbing and pulsating head pain. Migraine affects 2.6% and 21.7% of the general population and is the major cause of partial disability in the age group 15-49. Higher mutation rates, imbalance in concentration of physiologically relevant molecules and oxidative stress biomarkers have been the main themes of discussion in determining the role of mitochondrial disability in migraine. The correlation of migraine with other disorders like hemiplegic migraine; mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes [MELAS]; tension-type headache (TTH); cyclic vomiting syndrome (CVS), ischaemic stroke; and hypertension has helped in the assessment of the physiological and morphogenetic basis of migraine. Here, we have reviewed the different nuances of mitochondrial dysfunction and migraine. The different mtDNA polymorphisms that can affect the generation and transmission of nerve impulse has been highlighted and supported with research findings. In addition to this, the genetic basis of migraine pathogenesis as a consequence of mutations in nuclear DNA that can, in turn, affect the synthesis of defective mitochondrial proteins is discussed along with a brief overview of epigenetic profile. This review gives an overview of the pathophysiology of migraine and explores mitochondrial dysfunction as a potential underlying mechanism. Also, therapeutic supplements for managing migraine have been discussed at different junctures in this paper. more...

As part of our ongoing investigation on the chemical and biological properties of piperazinium salts, we synthesized three novel compounds: 1-ethylpiperazinium 3,5-dinitrobenzoate (I), 1-methylpiperazinium 3,5-dinitrobenzoate (II) and 1-methylpiperazinium 4-iodobenzoate (III). The crystal structures of these compounds are built up of organic layers formed by the strong connection between the molecules by hydrogen bonds of type N—H...O. These layers are linked through N—H...O hydrogen bonds and C—H...O interactions or C—I...N halogen bonding, leading to the formation of a three-dimensional network., Funding for this research was provided by: Spanish Ministerio de Ciencia e Innovacion (grant No. PID2020-113558RB-C41 to Santiago Garcia-Granda); Gobierno del Principado de Asturias (grant No. GRUPIN-ID2018-170 to Santiago GarciaGranda); University of Mysore (grant to Sriramapura D.
