    Abstract

    A series of Eu3+ doped MGd2Si3O10 (M = Mg2+, Ca2+, Sr2+ and Ba2+) was synthesized via sol-gel procedure at 950 oC. The optical characteristics of the materials were studied by Photoluminescence (PL) emission spectra. Upon 395 nm excitation and at 0.03 mole concentration of Eu3+ ion, these nanophosphors display optimum photoluminescence with most intense peak due to 5D0→7F2 (614-616) of dopant. Powder X-ray diffraction (PXRD) analysis proves that all synthesized materials are of crystalline nature and crystallinity improves on increasing temperature. Transmission electron microscopy (TEM) exhibited the spherical shape of particles in 13-30 nm size. Fourier Transformation infrared (FTIR) spectra showed peaks in 400-1000 cm-1 corresponding to gadolinium-oxygen and silicon-oxygen bond vibrations. In BaGd2Si3O10 material, Gd-O vibration is centered at 492 cm-1 and absorption band at 855 cm-1 is result of asymmetric vibrations of SiO in silicate tetrahedral unit. Due to excellent photoluminescence and suitable CIE coordinates, these materials could have brilliant applications in innovative displays.

    Research Highlights

    • Series of trivalent europium doped MGd2Si3O10 (M = Mg2+, Ca2+, Sr2+ and Ba2+)fluorescent materials were synthesized successfully with sol-gel procedure.
    • The prepared samples were characterized using Photoluminescence analysis, X-ray diffraction study, Transmission Electron Microscopic analysis and Fourier Transform Infrared spectroscopy.
    • The CIE color coordinates values of phosphor confirmed the red color of complex approving the PL results.
    • X-ray diffraction pattern of these materials determined the particle size using Debye Scherrer’s equation.
    • Excellent photoluminescence response and nano size of these materials made them suitable for various innovative display applications.

    Abstract

    Nanoparticle ferrite with chemical formula CoFe2O4 was prepared from the Co (II) and Fe (III) 3-acetyl-4-hydroxy-coumarin metal complexes by solution based one-pot microwave assisted technique. Single phase structure of CoFe2O4 ferrites nanoparticles was confirmed using FTIR, XRD, SEM, and EDX analysis. Transmission Electron Microscope (TEM) showed that the particle size of the samples in the range of (15 nm). The hysteresis studies showed ferromagnetic behaviour at room temperature. The antifungal activity of CoFe2O4 nanoparticle was investigated against A.flavus and A. niger by employing disc diffusion method. According to the results obtained, CoFe2O4 is a potential material for antifungal diseases. The CoFe2O4 nanoparticles could be readily separated from water solution after the disinfection process by applying an external magnetic field.

    Abstract

    Doxorubicin (Dox), an antineoplastic drug, has been extensively used for the treatment of different cancers. Dox is hydrophilic and therefore distributes to normal organs at a faster rate. Due to its required high doses, it poses severe toxicity, such as cardiotoxicity and nephrotoxicity. Diverse approaches, including nanoparticulate delivery systems, have been designed and evaluated to improve its delivery to the target site and reduce toxicity to normal organs; however, this has met little success. Here in this review, we have discussed various systems (metal nanoparticles, carbon nanotubes, fullerenes, liposomes, dendrimers, cyclic peptides, and other covalent/non-covalent systems) that have been used for Dox. We have critically evaluated their designing and outcome (in vitro and in vivo) with potential applications in the clinical setting.

    Abstract

    Despite the noteworthy advances in the use of chemotherapy for malaria, it continues to constantly affect large number of individuals. New molecules capable of blocking life-cycle of the parasite, preferably through targeting novel pathways and various modes of action, are increasingly becoming area of interest. Phenotypic screening of large chemical libraries is certainly one of the important criteria for the discovery of new and effective drugs. In recent years, diverse research groups including pharmaceutical industries have performed this large-scale phenotypic screening to identify the potential drug molecules. Most of the antimalarial drugs target blood-stage malarial infection and remain either less potent or ineffective against other life stages i.e. liver-stage, and the gametocyte stages of the parasite. Although, liver stage is considered as a crucial drug target, limited clinical options have significantly hampered the discovery of effective treatments. This short review presents the collection of selective molecules targeting specifically liver stage malaria parasites.

    Abstract

    2-Methyl-1,2,3,4-tetrahydroquinolin-4-yl)pyrrolidin-2-ones (3a−g) were synthesized by one pot multicomponent aza Diels-alder reaction between N-arylimines with two molecules of N-vinyl-2-pyrrolidinone in presence of Sm(III)nitrate as catalyst in acetonitrile solvent at room temperature stirring. The photocleavage studies with 2-methyl-1,2,3,4-tetrahydroquinolin-4-yl)pyrrolidin-2-ones (3a−g) revealed that almost all derivatives exhibited effective photocleavage of pUC−19 DNA at 365 nm, The The anticancer activities of newly synthesized compounds (3a−g) were more potent than doxorubicin on MCF−7 cells. The docking of PBR receptor (1EQ1) protein with newly synthesized THQ’s (3a-g) exhibited well established bonds with one or more amino acids in the receptor active pocket.

  • Pharmacy periodicals in India – a review by research

    by Prof. Anant Hardas

    Published in Journal of Biomedical and Therapeutic Sciences BiomedFrontiers section (Print)

    The first issue of Pharmacy Journal in India – The Indian Journal of Pharmacy was published in Dec 1894, however it was defunct after 3 years. The Modern Pharmaceutical Journalism in India was Pioneered by Mr. Premnath Bazaz, who started the Eastern Pharmacist in 1958 and equal contribution was by Dr. A.K. Patni, who edited Indian Drug since its inception published by IDMA. Today there are nearly 175 Pharmacy Journal published in mostly English (and also in Marathi, Hindi & Bengali) by 5 different categories of publishers in India. The PCI has set out official Journals – seven – for D. Pharm Course and 20 for B. Pharm Degree Course, and minimum 2 international Journals for each discipline of specialization at M. Pharm, Ph.D and Pharm. D Courses structure in India. This article brings out short History and progress of Indian Pharmacy Periodical as on today.

    Abstract

    In this paper, we report the fabrication of carbon nanofibers (CNFs) by electrospinning of polyacrylonitrile (PAN) solution in N,N-dimethylformamide (DMF)with different concentrations followed by stabilization and carbonization in a tubular quartz furnace. To improve the electrochemical performance, graphene nanosheets have been used to prepare porous graphene/carbon nanofibers (G-CNFs). The morphology of the porous G-CNFs were characterized by means of scanning electron microscopy (SEM). Diameter of CNFs and G-CNFs were found to be in the range of 400 – 500 nm reveals the fibers in nanoscale with high porosity. The electrochemical performance of as-synthesized CNFs and G-CNFs was studied by cyclic voltammetry (CV), galvanostatic charge discharge (GCD) and electrochemical impedance spectroscopy. The CV curve of the pure CNFs show distorted rectangular shape whereas CV curve of G-CNFs exhibit a nearly rectangle-shaped profile which is the characteristic of an ideal electric double-layer capacitor. The improved electrochemical performance of G-CNFs is due to the improved internal electrical conductivity of G-CNFs via graphene nanosheets interlaying.
