Cancer is a dreadful disease and any practical solution in combating this disease is of paramount importance to public health. In recent years, medicinal plants have attracted a lot of attention globally. Many herbs have been evaluated and are currently being investigated phytochemically to understand their anti-tumor actions against various types of cancers. Abrus precatorius L. - Family Fabaceae is a medicinal herb used for many diseases. The ethnomedicinal properties mentioned in the literature are antitumor, antifertility, antihelminthic, insecticidal, anti-inflammatory, antidiabetic and antibacterial. In the present investigation, four different extracts (viz. Aqueous, Ethanolic, Methanolic and Petroleum ether) of seeds of Abrus precatorius L. were analysed for their preliminary phytochemical constituents, whereas five different extracts (viz. Aqueous, Hydroalcoholic, Ethanolic, Methanolic and Petroleum ether) of seeds of Abrus precatorius L. were analysed for in vitro anticancer activity and HPTLC fingerprint. Preliminary phytochemical analysis of extracts of seeds of Abrus precatorius L. was carried out. Sulforhodamine B (SRB) assay was carried out for in vitro anticancer activity for five different extracts (viz. Aqueous, Hydroalcoholic, Ethanolic, Methanolic and Petroleum ether). HPTLC fingerprint profile was also developed and standardized for these extracts. The preliminary phytochemical analysis of extracts of seeds of A. precatorius L. showed presence of aleurone grains, amino acids, proteins, fats and fixed oils, tannins, alkaloids, steroids, glycosides, mucilage and flavonoids. In vitro anticancer activity was studied against 19 Human Cancer Cell Lines namely Cervix (ME180, SiHa), Leukemia (HL60, K562), Ovarian (A2780, Ovkar-3), Breast (MCF-7, MDA-MB-468, MDA-MB-435, MDA-MB-231, ZR-75-1, BT-474), Prostate (PC3, DU145), Colon (HT29, Colo205), Lung (A549), Hepatoma (HEPG2) and Oral (AW13516). Out of the 5 extracts and 19 cell lines used for studying anticancer activity, the Hydroalcoholic and Petroleum ether extracts of seeds of Abrus precatorius L. were active on Human Breast Cancer Cell Lines MCF-7 and Zr-75-1 respectively. The anticancer activity of Hydroalcoholic and Petroleum ether extracts of seeds of Abrus precatorius L. may be related to its flavonoid, terpenoid, alkaloid and protein contents. HPTLC fingerprint profile developed is unique to extracts of seeds of Abrus precatorius L. © 2015, Global Research Online. All rights reserved.

The fruits of Averrhoa bilmbi L. are used to treat skin disorders, fever, for scurvy and beneficial in diarrhoea, hepatitis and in inflammatory condition. It is also used to treat hyperlipidaemia and possess potential antibacterial and antioxidant activity. Pharmacognostical standards on bilimbi fruits are not yet available for correct identification of plant material and to ascertain its quality and purity. The present investigation was therefore undertaken to determine the requisite pharmacognostical standards according to the Pharmacopoeial guidelines for evaluating the fruit. Pharmacognostical evaluation included examination of morphological and microscopical characters, physicochemical properties, phytochemical analysis, fluorescence study and HPTLC fingerprint. The powder microscopy showed the presence of simple and glandular trichomes and spiral thickening of vessels. Phytochemical screening reported the presence of carbohydrates, proteins, amino acids, flavonoids, tannins and hydrolysable tannins. The HPTLC fingerprint developed for the separation of phytoconstituents is unique to A. bilimbi L. fruit powder. HPTLC fingerprint has been developed; as the chemical fingerprint obtained by chromatographic techniques are strongly recommended for the purpose of quality control of herbal medicines. This unique band pattern obtained from HPTLC fingerprint can be used for the identification of A. bilimbi L. fruits. These studies provide referential information for correct identification and standardization of A. bilimbi L. fruit. © 2012, JPR Solutions.

Curcumin, an ingredient of turmeric, exhibits a variety of biological activities such as anti-inflammatory, anti-atherosclerotic, anti-proliferative, anti-oxidant, anti-cancer and anti-metastatic. It is a highly pleiotropic molecule that inhibits cell proliferation and induces apoptosis in cancer cells. Despite its imperative biological activities, chemical instability, photo-instability and poor bioavailability limits its utilization as an effective therapeutic agent. Therefore, enhancing the bioavailability of curcumin may improve its therapeutic index for clinical setting. In the present study, we have conjugated curcumin with a biodegradable polymer Poly (D, L-lactic-co-glycolic acid) and evaluated its apoptotic potential in human colon carcinoma cells (HCT 116). The results show that curcumin-PLGA conjugate efficiently inhibits cell proliferation and cell survival in human colon carcinoma cells as compared to native curcumin. Additionally, curcumin conjugated with PLGA shows improved cellular uptake and exhibits controlled release at physiological pH as compared to native curcumin. The curcumin-PLGA conjugate efficiently activates the cascade of caspases and promotes intrinsic apoptotic signaling. Thus, the results suggest that conjugation potentiates the sustainability, anti-proliferative and apoptotic activity of curcumin. This approach could be a promising strategy to improve the therapeutic index of cancer therapy. © 2015 Waghela et al.

Water samples were collected from 25 sampling sites during the pre-monsoon season in Ulhasnagar city, Thane district in Mumbai. Different physicochemical parameters were measured and the samples were also analyzed for dissolved metal concentrations. The surface water physicochemical parameters included pH, temperature, turbidity, hardness, total alkalinity, dissolved oxygen (DO), total dissolved solids (TDS), electrical conductance (EC) and turbidity while the dissolved metals were Cd, Cu, Pb and Cr. The ranges for the physicochemical parameters were 28-32 degrees C for temperature, 6.8-8.5 for pH, 0.4-12.8 mg/l for DO, 0-100 NTU for turbidity, 22-580 ppm (as CaCO3) for hardness, 44-61 ppm. for total alkalinity, 250-520 mg/l for TDS and 554-1040 mhos/cm while the dissolved metals (mg/l) were 0.001-0.008 for Cd, 0.002-0.012 for Cu, 0.04-1.30 for Pb and 0.000-0.15 for Cr. Based on multivariate analysis and correlation studies, lead was identified as major dissolved metal contaminant in most of the analyzed samples. Microbial analysis was also carried out by testing the samples for E. coli and thermo tolerant bacteria and ranges for these were from 2-18 ppm for E. Coli and 2-19 ppm for the thermo tolerant bacteria.

In this work, cotton cellulose/polyacrylic (CC/PAAc) composite fibers are produced by soaking plain cotton cellulose (CC) fibers in a reaction mixture containing monomer acrylic acid, crosslinker N,N-methylene-bis acrylamide (MB) and initiator potassium persulphate (KPS), followed by microwave induced in-situ formation of polyacrylic acid within cotton fibers. The fibers are characterized by TGA, FTIR and SEM analysis. The mechanical strength of CC/PAAc fibers was comparable to that of CC fibers, indicating marginal loss in mechanical strength. The antibacterial drug Gentamicin Sulphate (GS) was added to the reaction mixture before soaking the CC fibers in the reaction solution. This yielded GS loaded CC/PAAc fibers. The release of drug GS was investigated as a function of the amount of crosslinker in the soaking solution. It was found that the quantity of crosslinker MB in the soaking solution influenced the release mechanism. Fiber samples with relatively lower and higher amount of crosslinker followed Second order model and the Higuchi diffusion model, respectively. The CC fibers showed lower release as compared to the CC/PAAc fibers. Finally, the biocidal action of fibers was tested using a zone of inhibition method using E. Coli as model bacteria. The fibers demonstrated biocidal action by exhibiting zones of inhibition of diameter 1.3 and 2.2cm, respectively for fibers prepared by soaking in the reaction solutions containing 0.2 and 0.4 percent (w/v) drug. Finally, the killing kinetics was investigated to show time dependent bacterial killings for the fiber samples GSLCC/PAAc (0.2) and GSLCC/PAAc (1.2). © 2013 Copyright Taylor and Francis Group, LLC.

In this work, poly(acrylic acid) has been grafted onto cotton fibers through the free radical initiated polymerization and the resulting fibers have been characterized by Fourier transform infrared, thermogravimetric analysis, and scanning electron microscopy analysis. The grafted fibers have been loaded with copper nanoparticles using in situ approach. The Transmission Electron Microscopy (TEM) analysis of Cu nanoparticles revealed that almost 45% of the particles had a diameter range of 60–80 nm. The copper nanoparticles loaded fibers show slow release of Cu(II) ions, extended over a period of around 50 h. The release of Cu(II) ions followed a second-order kinetic model successfully. The fibers also exhibited an excellent antibacterial action against model bacteria Escherichia coli as tested by zone of inhibition method. © 2014, The Author(s) 2014.

To obtain effective drug with proven efficacy, it is necessary to establish standards through modern scientific and technical procedures which would certainly enhance the reputation and acceptance of traditional medicines. Sufoof-e-mohazzil, a unani polyherbal formulation is used by Unani physicians for treatment of obesity. The present work involves standardization of Sufoof-e-mohazzil in order to assess the quality of In-house and marketed formulations. In-house and marketed formulations were subjected to pharmacognostic studies, physico-chemical properties, phytochemical analysis and HPTLC fingerprint profile to set the standards, which can be used as reference standard to evaluate the quality control in herbal industries and to overcome batch to batch variations in traditional preparation. In the present study, the anatomical markers fibro vascular tissue, endospermic cells, vittae, pitted vessels and group of sclereids from the mesocarp were observed. The extractive values were found to be more for alcohol than water. The preliminary phytochemical analysis indicated presence of alkaloids, fats and fixed oils, essential oils, glycosides, resins and saponins. HPTLC fingerprint profile of formulations showed a characteristic pinkish red band of Thymol at Rf of 0.43.
