The seeds of Vitis vinifera have been shown to have antioxidant, anticancer and antimicrobial properties due to the presence of rich bioactive phenolic components like resveratrol. The research deals with the synthesis of silver nanobioconjugates from the methanolic extract of grape seeds and the pure compound resveratrol. The presence of resveratrol was confirmed by HPLC analysis in methanolic extract of various parts of grape fruits such as skin, pulp and seeds of two varieties (pink and black). As higher amount of resveratrol was present in the seed extract of pink grapes, it was selected for the silver nanobioconjugate synthesis. Various conditions were applied to influence the rapid reduction of Ag+ to Agο, such as microwave heating, water bath heating, sunlight exposure and incubation at 37οC for nanobioconjugate synthesis. The reduction of silver ions was confirmed by color changes, adsorption spectroscopy (280-800nm) and percentage yield. Among the four different methods, sunlight exposure proved to be rapid in the synthesis and the yield of nanobioconjugates was also high. Therefore, this method...

In vitro antibacterial activity of Bryophyllum pinnatum (in vivo generated and in vitro regenerated roots) were analysed in this study. Traditional uses for these plants treat specific conditions or diseases. The present study examined the antibacterial activity using the disk diffusion method using Ethanolic & Methanolic extract as part of the process of understanding the chemistry, toxicity and efficacy of these plant extracts. Methanolic and Ethanolic extracts of this plant was examined using a standard antimicrobial disk diffusion method. Extracts were tested against both Gram negative (Escherichia coli, Vibrio cholerae, Salmonella typhi and Pseudomonas aeruginosa) & Gram positive (Bacillus cereus & Staphylococcus aureus) bacteria. Methanolic in vitro regenerated roots showed higher inhibition zone against all bacterial species while natural growing plant root extract showed minimum inhibition. In vitro regenerated root extract showed moderate inhibition zone against all bacterial species. S. aureus showed maximum (25.2 mm) inhibition zone in in vitro root methanolic extract while V. cholerae showed minimum (14 mm) in natural growing root extract. In ethanolic extract maximum...

Affordability to healthcare is one of the major factors that have impact on the health care access in the Indian subcontinent. It is the main responsibility of the pharmacist in ensuring that patients get the right drug in the right quantity at the right time. Thus, such prescription pattern monitoring studies can promote appropriate use and reduction of abuse or misuse of monitored drug. The aim of such studies is to facilitate the rational use of drugs in the population. Irrational use of medicines leads to increased incidence of treatment failure, antimicrobial resistance and economic burden on the patient and the community as a whole. This is a descriptive observational prospective study in monitoring the drug prescription pattern in an ENT outpatient department. The objective of this study is to evaluate the patterns of drug prescribing practised. The study conducted observed that the drug prescription pattern was not as per the WHO guidelines and its indicators. ENT disorders led to school absenteeism as most of them where school going...

The natural acid like lemon juice provides mild acidic state which used to catalyzed reaction of primary amine and aldehyde in green solvent like ethanol at room temperature reflux for 1.5 hour gives Schiff bases in good yield. Schiff bases have attracted considerable attention of us due to their significant biological activities 1 like anticancer, antitumor, anti inflammatory agents 4, insecticidal, antibacterial 5, antituberculosis, antimicrobial 2-3, antifungal 5, anti-HIV and metal corrosion inhibition activities of Schiff bases, besides wide range of pharmacological activities. Natural acid is non-polluting and does not employ any lethal materials, quantifying if as a green approach for the synthesis of Schiff bases. Schiff bases also have several types of biological actions such as analgesic and antimalerial 6. They are working as Ligands for complexes of metal ions. Organosilicon complexes with Schiff bases are found to be beneficial in various agricultural applications like fungicides, bactericides, herbicides, acaricides and antifeedants 7. The metal complex of Schiff bases are also of principal significance in analytical chemistry and chemotherapy...

An antibiotic may be defined as a substance or compound that kills or inhibits the growth of, bacteria. Antibiotics belong to the broader group of antimicrobial compounds, used to treat infections caused by microorganisms, including fungi and protozoa, viruses. Antibiotic de-escalation is a mechanism whereby the provision of effective initial antibiotic treatment is achieved while avoiding unnecessary antibiotic use that would promote the development of resistance. The embodiment of de-escalation is that based on microbiology results around the day 3 therapy point; the empiric antibiotic(s) that were started are stopped or reduced in number and/or narrowed in...
