the toxicity of 7 herbicides to the three cyanobacteria was tested in this work. the results indicated that: (1) there was a highly significant relationship between dried weight or chlorophyll-a and od680nm for tested cyanobacteria; (2) the toxicity of the tested herbicides with the order from high to low was: photosynthesis-inhibiting > accase inhibitor > protox inhibiting herbicides; (3) the ...

Fibroblast growth factor receptors (FGFRs) play an important role in determining cell proliferation, differentiation, migration, and survival. Although a variety of small-molecule FGFR inhibitors have been developed for cancer therapeutics, the interaction between FGFRs and FGFR inhibitors has not been well characterized. The FGFR-inhibitor interaction can be characterized using a new imaging p...

Using natural plant extracts on metallic substances is the most frequently studied green corrosion inhibition approach in science. In this work, Coriaria nepalensis Stem Alkaloid (CNSA) has been successfully extracted and characterized by qualitative chemical (Mayer’s Dragendroff’s) test spectroscopic (UV FTIR) measurement. CNSA employed as a inhibitor for Mild Steel (MS) subjected to 1 M H2SO4...

Wild-type cells of the unicellular green alga Chlamydomonas reinhardi have been grown for several generations in the presence of rifampicin, an inhibitor of chloroplast DNA-dependent RNA polymerase, spectinomycin and chloramphenicol, two inhibitors of protein synthesis on chloroplast ribosomes, and cycloheximide, an inhibitor of protein synthesis on cytoplasmic ribosomes. The effects of cyclohe...

In a first step toward understanding the molecular basis of pineapple fruit development, a sequencing project was initiated to survey a range of expressed sequences from green unripe and yellow ripe fruit tissue. A highly abundant metallothionein transcript was identified during library construction, and was estimated to account for up to 50% of all EST library clones. Library clones with metal...

background: leukemia inhibitor factor (lif) is a very important pleiotropic cytokine which belongs to interleukin-6 (il-6) family. lif exerts multiple effects on different types of cells and tissues with numerous regulatory effects in vivo and in vitro. it is a lymphoid factor, which performs a number of activities including cholinergic neuron differentia­tion, control of stem cell pluripotency...

Quinone, Photosynthetic Electron Transport, Inhibitor UHDBT (5-«-undecyl-6-hydroxy-4,7-dioxobenzothiazole) is an efficient inhibitor of photosyn­ thetic electron transport in chloroplasts from spinach (pl50-value = 7.61) and the green alga Chlamydomonas reinhardii. At low concentrations of UHDBT its site of inhibition is located at the reducing side of plastoquinone, identical to that of 3-(3,4...

Abstract Gongronema latifolium was used as a low-cost green inhibitor for mild steel by applying the weight loss method at 303–323 K. There decrease in percentage inhibition with temperature increase and rise efficiency an concentration of inhibitor. The obtained results showed that extract methanol had efficiencies range 59.06–81.69%. Corrosion good fit to Langmuir model compared Freundlich El...
