Opis:
Fort et al. (2010) have written another useful article on flow characteristics generated by axial high speed impellers. I agree with the authors that the knowledge of flow patterns is crucial for developing reliable design procedures for instance, for mixing and blending (Baldyga and Bourne, 1997; Nienow, 1997; Ranade et al., 1991), for solid suspension (Raghva Rao et al., 1988; Zwietering, 1958), for gas induction (Joshi and Sharma, 1977) and bioreactions where controlled shear is important (Joshi et al., 1996). With this context, the work of Fort et al. (2010) needs some clarification and further extension.

Opis:
Cayratia trifolia Linn. Domin Syn. Vitis trifolia (family: Vitaceae ) contains polyphenols as major bioactive compounds. Plant polyphenolics, such as stilbenes, possess a broad spectrum of pharmacological and therapeutic effects, including antioxidative, anticancerous, antiatherosclerotic, cardioprotective, hepatoprotective, and neuroprotective effects. Elicitation is one of the important strategies to enhance secondary metabolite production in cell suspension cultures. In the present study, the effect of two biotic elicitors, namely one fungal (Fusarium sp., and Helminthosporium sp.) extract and another higher plant-originated gum (Anogeissus latifolia ), was evaluated for enhanced production of stilbenes in cell suspension culture of C. trifolia. For the fungal elicitor, the cell suspension cultures of C. trifolia were treated with varying concentrations of Fusarium extract (FE) and Helminthosporium extract (HE) on the 7th day of culture. Increasing concentration of FE in the medium resulted in slightly decreased cell growth but increased the production of stilbenes, with the optimal concentration at 1000 mg/l. This increase in the yield of stilbenes was -5 times (9.30 mg/l) higher than the control value. HE was less effective than FE in increasing stilbene production at optimal concentrations. The addition of 50 mg/l A. latifolia plant gum sieved through a 150 mesh (0.1 mm) to C. trifolia cell culture enhanced stilbene accumulation and yield by 8- to 9-fold over the control value.

Opis:
Some novel 6-fluoro chroman derivatives having 1,2,4-triazolo-[3,4-b]thiadiazole were synthesized and characterized by IR, NMR and mass spectral analysis. All synthesized compounds were screened for antimicrobial activity using broth dilution method. All the compounds showed good antimicrobial activity and compound 5e showed significant antibacterial activity.

Opis:
A series of (4-(7-chloroquinolin-4-yl)piperazin-1-yl)(substitutedphenyl)methanones were prepared via multistep synthesis which involved acrylation without base, cyclisation, hydrolysis, decarboxylation, electrophilic chlorination reactions and subsequent chloro-amine coupling with various substituted benzoyl chloride derivatives. The structure of the synthesized compounds was established by using elemental analysis, FT-IR, 1H NMR, 13C NMR and Mass spectroscopy. All the novel compounds have been tested on thin layer chromatographic plate for purity and evaluated for their antimicrobial activity against gram positive and gram negative bacteria which demonstrated moderate to good antimicrobial activity.
