Synthesis and multi‐spectroscopic study on DNA‐binding, cleavage and biological properties of M(II) complexes based on N2O2 donor Schiff base ligand

Abstract: A novel Schiff base, (S,Z)-4-(methylthio)-2-((3-oxo-2,3-dihydro-1H-inden-1-ylidene)amino)butanoic acid (L) and four M(II) complexes (where M = Co, Cu, Ni and Zn) were synthesized and characterized. The DNA-binding characteristics of the complexes were investigated using various spectroscopic methods and viscosity measurements. Analysis of the results suggests that all the complexes bind to calf thymus DNA via intercalation. Among the four, Cu(II) complex was found to promote the photocleavage of plasmid DNA pBR322 under irradiation at 365 nm. These complexes also exhibit good antioxidant activities against 2,2-diphenyl-1-picrylhydrazyl radical. In vitro antibacterial and antifungal assay indicates that these complexes are good antimicrobial agents.

Nanoparticulated polymeric composites enfolding lithium carbonate as brain drug in persuading depression: an in vivo study.

Abstract: Lithium carbonate is considered an effective drug against mania and acts as a mood stabilizer. It is found that it enhances antidepressants targeting depression, consequently it is prone to have risk factors that leads to adverse effects. The study is devised in confronting depression under nanoscale by preparing nanocomposites which is a matrix of biopolymer chitosan that encapsulates lithium carbonate by ionic gelation method. This facilitates the drug delivery in a regulated manner targeting the therapeutic action with a limited dosage that lessens the side effects in the course of treatment. The drug polymer interaction was validated by XRD studies, whereas the morphology and size characterization by SEM and zetasizer. The average particle size was determined as 193 ± 0.18 nm with a positive zeta potential of 37.9 mV. The in vitro drug release patterns of nanocomposites were comparatively assayed with the standard lithium carbonate which rendered a controlled release in its profile. The in vivo investigation by animal despair studies bestowed a significant difference in the duration of immobility during force swimming and tail suspension tests. These results were substantiated with histopathological examinations of cerebral cortex region which showed mild cellular edema, degenerative changes and lymphocytic infiltration when compared with the control groups. Consequently, the efficacy of nanocomposites encased with lithium carbonate fortifies targeted drug delivery and restrains adverse effects by endorsing it as a lead compound in brain drug developmental research.

NPASA: A Noble Path Selection Algorithm

Abstract: As the network is growing exponentially, challenges and issues also increases. They affect the performance of the network. Many factors contribute to improve the performance of the network. One such factor is finding the path quickly. In this paper, we are going to find a shortest path faster compared to Dijkstra's shortest path algorithm. We have introduced new ideas in building the end-to-end path. Various steps involved in finding the shortest path are refined. The simulated algorithm shows better results than the existing algorithm. We are sure that, the outcome of this paper reduces computation overhead and processing overload.

Template-free and cost-effective nebulizer spray-coated BiVO 4 nanostructured thin films for photocatalytic applications

Abstract: The present study reports on facile deposition of single-phase BiVO4 thin films by nebulizer spray pyrolysis route for different spray volumes (5, 10, 15, and 20 ml). The main objective is to identify the optimum thickness and morphology of BiVO4 films for enhanced photocatalytic performance. The physical properties of the films were characterized using different analytical techniques. Highly compact and flake-like structures in BiVO4 film were resulted for higher spray volume without any aid of additive or template in the preparation procedure. Nanoflake BiVO4 film possessed high optical absorption, effective charge carrier transport properties, and high penetration depth, and exhibited maximum photodegradation efficiency for the treatment of rhodamine B and methyl orange dyes.

A technical study on Information Retrieval using web mining techniques

Abstract: Information Retrieval (IR) is a significant area in web mining where the users procure their needed information from the web. The documents in the web are in the form of web pages. As there is a high usage of data in the web, researchers are intended to do research in the field of IR. Web query classification and web page classification are leading major role to classify the web documents in IR using classification algorithms, based on the user query. The classified documents are indexed using ranking algorithm. This research paper aims to study about various methods of IR to classify and index the relevant web pages respectively.
