This study was undertaken to investigate the antimicrobial activities of aqueous and ethanol extracts of violet plant, Securideca longepedunculata leaves and root bark extracts against the pathogenic bacteria isolates of Salmonella typhi, Escherichia coli and Pseudomonas aeroginosa. Disc diffusion method was used for antibacterial testing and Tetracycline drug at 250 mg/ml concentration was used as positive reference standards to determine the sensitivity of the strains. The results of the antibacterial activities revealed that the highest growth inhibition of the tested bacteria was recorded as 8.00±1.00mm at 250 mg/ml, followed by 7.67±1.15mm at 250 mg/ml and the least inhibition was 3.00±2.00mm at 100 mg/ml. The minimum inhibitory concentrations for E. coli and S. typhi were 124 mg/ml and 250 mg/ml respectively. The results showed significant effect (P < 0.05) of antibacterial activity; with the constituents of S. longepedunculata leaves and root bark extracts been used as potential antimicrobial agents in the management of microbial diseases caused by pathogenic bacteria species which may in turn be an alternative to chemical antibiotics....

The disease causing bacteria have evolved the genetic ability to transmit and acquire resistance to drugs used as therapeutic agents. The discovery of antibiotics to combat these pathogens marked a resolution in the 20th century. Unfortunately, because of the inappropriate use of antibiotics in human and veterinary medicine, certain strains of bacteria and fungi developed the ability to produce substances which block the action of antibiotics or change their target or ability to penetrate cells. One way to prevent antibiotic resistance is by exploring new bioactive compounds from traditional medicine which is not based on the existing synthetic antimicrobial agents. Phytochemicals from medicinal plants showing antimicrobial activities have the potential of filling this need, because their structures are different from those of the more studied microbial sources. The present study was conducted to evaluate the antimicrobial activity from ethanolic extract against different life threatening pathogenic microorganisms and screening for various phytochemical constituents of Lawsonia inermis Linn. According to the results obtained from current investigation, ethanolic extract of Lawsonia inermis...

Diabetes mellitus (DM) was found to impair all dimensions of health except mental health and pain and in a more recent multinational study, DM was found to have a notable impact on general health, measured using the Medical Outcomes Short-Form 36 (SF-36). A cross-sectional, randomized study conducted in Ajman and Sharjah, October 2012 to May 2013, using a self-completed questionnaire and SF-36 health related quality of life (HRQL) questionnaire by 150 diabetic patients on different types of medications and 220 control subjects. Forty four percent of patients used Insulin for their treatment, 34% used Metformin, 14.7% used combination therapy of Insulin with Metformin and only 6% used Gliclazide. The mean values of Physical Functioning (PF), Role-Physical (RP), Bodily Pain (BP), General Health (GH), Vitality (V), Social Functioning (SF), Role Emotional (RE), Mental Health (MH), Physical Components Summary (PCS), and Mental Components Summary (MCS) scores were 61.2, 19.5, 59.2, 56.5, 53.0, 55.4, 57.3, 55.6, 4, and 42.1, respectively. Patients taking an oral therapy had better quality of life than those...

L-asparaginase is responsible for the hydrolysis of L-asparagine into L-aspartic acid and ammonia. L-asparaginase is used as an effective therapeutic agent against lymphocytic leukemia. It also finds applications in food industry. Though much has been unraveled about LA, it may appears today that it is at the tip of iceberg and there is tremendous scope in screening of novel LA sources and studying their properties and applications. In the current study L-asparaginase producing bacteria were screened from forest soil of Vasai, MS, India. Modified M9 medium was used for screening the L-asparaginase producers. Out of the total 885 organisms screened for L-asparaginase production, one isolate was found to produce substantial L-asparaginase (15.94 IU/ml). This isolate was further identified by 16S ribosomal RNA gene sequencing as a novel strain Salinicoccus sp. M KJ997975. This orange pigment producing isolate was found to be moderately halophilic and alkaliphilic. Not much literature is available on L-asparaginase producing gram positive alkalophilic and halophilc bacteria and this is the first kind of report on L-asparaginase...

The contents of Sodium lauryl sulphate (SLS) and Polysorbate (Tween 80) were studied in different formulations of Nebivolol film coated tablets. The contents were extracted using the diluent Methanol: Water in the ratio 60:40 v/v and analyzed in HPLC coupled with Evaporative light scattering detector (ELSD). SLS and Tween 80 are solubilizing agents and the amount of these contents are critical in formulations as they are play a major role in the release pattern of the drug for in-vivo and in-vitro dissolution profiles. A reverse phase liquid chromatographic (RP-LC) method was developed for the quantification of Sodium lauryl sulphate (SLS) and Polysorbate (Tween 80). The method was optimized using buffer (prepared by dissolving 0.77g of Ammonium acetate taken in 2000mL milli-Q-water and then pH was adjusted to 4.5with dilute acetic acid solution) as mobile phase-A and Acetonitrile mobile phase-B. The flow rate was set at 1.0 mL min-1 and the column temperature was maintained at 40°C. The capability of specific method developed was demonstrated by studying the validation parameters...
