Research ArticleOpen accessEvery word in the titleINCREASED NUTRIENT SOLUTION CONCENTRATION DURING EARLY FRUIT DEVELOPMENT STAGES ENHANCES PUNGENCY AND PHENYLALANINE AMMONIA-LYASE ACTIVITY IN HOT CHILI (CAPSICUM ANNUUM L.)Parichat Dittakit, Thammasak ThongketThe effect of increased nutrient concentration during different fruit development stages on the yield, pun-gency and PAL enzyme activity in hot chili cv. ’Super hot’ was studied during August 2009-January 2010. The seedlings were planted in plastic containers containing 20 L of coconut-coir-dust substrate placed inside a plastic-roofed net house and received Resh’s Tropical Dry Summer nutrient solution at a … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 27 Dec 2013 · 7,492 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEVALUATION OF ANTIMICROBIAL ACTIVITY IN OLIVE (OLEA EUROPAEA) LEAF EXTRACTMukadderat Gökmen, Recep Kara, Levent Akkaya et al.In this study the antimicrobial activity of Olive Leaf Extracts (OLE) was screened against five gram-positive and five gram-negative bacteria. The antimicrobial activity was evaluated using disc diffusion and microdilution methods. The diameters of inhibition zones of the olive leaf extract were observed 13.33±2.08 mm against S. typhimurium and 21.67±1.53 mm against B. cereus. There was a similarity between the … …Current Research in Microbiology, Vol. 5, Issue 2 · 15 Jan 2015 · 15,214 accessesView PDFCite
Research ArticleOpen accessIn the keywordsACCUMULATION OF RADIONUCLIDES BY PYLAISIELLA MOSS (PYLAISIA POLYANTHA) UNDER URBOECOSYSTEM CONDITIONST. V. Varduni, T. M. Minkina, E. A. Buraeva et al.Contamination of environment by radionuclides in territories under urboecosystem conditions is actual problem. The search of new express methods for radioactivity determination of environment is important task of research. In present work it was shown that mosses are bioindicators of radioactive contamination, because they accumulate radioactive substances in high concentrations. Using of bryoindication methods are promising techniques for the assessment … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 1 Dec 2014 · 6,450 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAntibacterial Activity of β-Cyclodextrin and 2-Hydroxypropyl-β-Cyclodextrin Trimethoprim ComplexesHsien-Kuo Sun, Madhumathi Seshadri, Scott Lingard et al.Problem statement: Cyclodextrin complexation has previously been shown to improve the solubility and dissolution properties of trimethoprim; however, no report provides an account of the effect cyclodextrin complexation has on the antibacterial activity of this agent. Approach: β-cyclodextrin and 2-hydroxypropyl β-cyclodextrin inclusion complexes of trimethoprim were prepared and confirmed by differential scanning calorimetry and proton nuclear magnetic resonance. The in-vitro … …Current Research in Microbiology, Vol. 2, Issue 1 · 26 Oct 2011 · 14,801 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimum Conditions for Measuring Dehydrogenase Activity of Aspergillus niger using TTCA. E. Ghaly, N. S. MahmoudThe suitability of the triphenyl tetrazolium chloride (TTC) for dehydrogenase activity measurement of the vegetative cells of the fungal species Aspergillus niger was investigated. The triphenyl formazan (TF) yield increased with the increases in TTC concentration, pH, temperature and incubation time within the studied ranges. The effects of individual parameters, as well as the combined effects, on the TF yield … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 9,002 accessesView PDFCite

Research ArticleOpen accessIn the abstractQualitative Analysis of the Chemical Composition of Cinnamomum tamala leaves and Biological ActivityQianwen Gong, Pin Chen, Linyang Wang, Shuge TianCinnamomum tamala (Buch.-Ham.) Nees and Ebermaier. (Lauraceae) is a less explored medicinal plant in Uyghur medicine, with limited knowledge about its non-volatile compounds. We utilized chemical pre-screening in conjunction with UPLC-Q-Orbitrap-MS to analyze the phytochemical makeup of C. tamala leaves. Total polyphenols were measured using the Folin-Ciocalteu method, while total flavonoids were quantified through NaNO2-Al (NO3)3 colorimetric analysis across four … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 21 Sep 2026 · 659 accessesView PDFCite
