In the present study, the endophytic actinomycetes were collected from three medicinal plants Azadiracta indica, Ocimum sanctum and Phyllanthus amarus. Endophytic actinomycetes were isolated using different media like Starch casein agar, Starch casein nitrate agar, Actinomycetes isolation agar and Soyabean agar, while it showed more colonies in Starch casein agar. The endophytic actinomycetes were stained and biochemical tests were performed. Antimicrobial compound was purified from the filtrate by ethanol extraction method. Antagonistic activities of endophytic actinomycetes isolates were tested against bacterial pathogens (Staphylococcus aureus, Streptococcus pyogenes, Klebsiella pneumoniae and Pseudomonas aeruginosa) and the fungi Rhizopus. For the selected isolates antibiotic resistance was checked using various antibiotic discs like Amoxycillin, Penicillin, Rifampicin and Ampicillin. The strains which showed efficient antibacterial activity were selected to study the effect of mutation by physical and chemical method. In this study, UV mutated endophytic actinomycetes increase antibiotic production than non-mutated endophytic Actinomycetes, whereas in chemical mutation it does not increase the antibiotic...

Cancer is a group of disease characterized by unregulated cell growth and spread of cells from site of origin to other sites in body. Two main genetic changes lead to cancer they are inactivation of tumour suppressor gene and activation of proto-oncogene. Ras gene is a proto-oncogene, when this gene activated it stimulates signalling pathway and that causes unregulated proliferation of cells. Ras family is a group of three precursors H-Ras, K-Ras and N-Ras. It was analyzed that more than 30% of cancers occurs due to Ras gene. But most of the Ras related cancers are occur due to mutations in H-Ras gene. In H-Ras gene codons 12, 13 and 61 are hotspots. Bioinformatics tools are help to find out the amino acid sequence from which got the gene sequence of H-Ras. Using the H-Ras gene sequence, six primer pairs were designed to amplify the DNA of patients with the potential mutations. Designed primers can be used for the diagnosis of H-Ras related...

FDTs are designed to disintegrate rapidly on contact with saliva and enables oral administration without water or chewing, these formulations offer increased convenience and ease of administration with the potential to improve patient compliance, particularly in certain populations, where swallowing of conventional solid oral dosage forms presents difficulties. In the present study, the effect of a natural superdisintegrant Fenugreek and synthetic superdisintegrants sodium starch glycolate (SSG) was compared in the formulations of fast dissolving tablets (FDT). FDTs of Diclofenac (model drug) were prepared by direct compression method. These tablets were evaluated for weight variation, hardness, thickness, disintegration time, water absorption ratio, friability and dissolution. Swelling index was also investigated with an aim to compare the swelling property of Fenugreek with Sodium starch glycolate (SSG). Fenugreek showed higher swelling index than SSG. Hence, the present study revealed that this natural superdisintegrants showed better disintegrating property than the most widely used synthetic superdisintegrants like...

The objective of this study was to conduct a survey and determine the barriers to implement performance-based management in pharmacies in Trinidad. PBM is defined as “a systematic approach to performance improvement through an on-going process of establishing strategic performance objectives, measuring performance, collecting, analyzing, reviewing, and reporting performance data, and using that data to drive performance improvement”(Performance Management Handbook). A questionnaire was conducted, with respect to the presence or absence of barriers to implementation of performance-based management at pharmacies along the East-West corridor of Trinidad. A twenty-two (22) question survey was administered to sixteen (16) pharmacies to be assessed. This region was chosen because of its close proximity and convenience. Fourteen (14) of the twenty-two (22) questions were based on a Likert-type scale, so that respondents were able to specify their level of agreement or disagreement of applicability on a symmetric “strongly agree – strongly disagree” scale for a series of statements based on the barriers of PBM implementation. Pharmacies were selected in a non-randomized manner. The SPSS...

Pluchea lanceolata has been used in massage oil as well as in traditional ayurveda as a potent pain reliever. The traditional Method of obtaining oil is simply based on taking water as the medium for extraction. The water extract obtained is then boiled with oil, till the water is completely evaporated. Here, our aim is to replace water by different organic solvents and obtain oil which has much better efficacy than the traditionally extracted oil. The idea here is to obtain more efficacious oil than the marketed sample which is majorly extracted using water as solvent. Here, the different organic solvents used are methanol, ethanol, petroleum ether and chloroform. The oil obtained was checked for its anti-inflammatory activity with the carrageenan induced rat paw edema. The prepared oil was compared with the marketed sample of mahanarayan oil. The ethanolic extract has showed to be having high extract yield in...
