This study aims at modelling the daily concentrations of nonylphenolic compounds such as 4-nonylphenol (4-NP), nonylphenol monoethoxylate (NP1EO) and nonylphenoxy acetic acid (NP1EC) within the Seine River downstream of Paris City for over a year, firstly in the present state (year 2010) and for years 2050 and 2100 in order to assess the consequences of global change on the fate of nonylphenoli...

generally, fruit trees should produce sufficient yield annually through their economic life. fruit trees usually produce flowers over their ability of productivity. if all of the flowers are converted to fruit, the tree will be weak and poor smaller fruit will be produced and it may cause alternate bearing. thus some flowers must be removed by hand, mechanically or chemically. in this study, th...

vanadium supported on highly ordered nanoporous silica (vox-lus-1) was synthesized and characterized by xrd, nitrogen adsorption‑desorption isotherms and uv-visible spectrophotometer. direct oxidation of benzene to phenol in liquid phase by h2o2 peroxide were examined by using various solvents (methanol, acetone, acetic acid, acetonitryl). the maximum yield (25%) and selectivity (73%) of the ph...

Previously, we found that orally administered acetic acid decreased lipogenesis in the liver and suppressed lipid accumulation in adipose tissue of Otsuka Long-Evans Tokushima Fatty rats, which exhibit hyperglycemic obesity with hyperinsulinemia and insulin resistance. Administered acetic acid led to increased phosphorylation of AMP-activated protein kinase (AMPK) in both liver and skeletal mus...

Peroxidase catalyzes the oxidation of indole-3-acetic acid. The primary products of this reaction stimulate growth in plants. Therefore, our concept is that an increase in peroxidase activity will increase the effect of indole-3-acetic acid as a growth hormone. Our objective was to study the effect of 2,3,5-triiodobenzoic acid, a growth regulator, on isoperoxidases in the cell wall and cytoplas...

To elucidate the mechanism underlying the action of dietary vinegar on antithrombotic activity, acetic acid, the main acidic component of dietary vinegar, was used to determine antiplatelet and fibrinolytic activity. The results revealed that acetic acid significantly inhibits adenosine diphosphate (ADP)-, collagen-, thrombin-, and arachidonic acid (AA)-induced platelet aggregation. Acetic acid...

Acetic acid bacteria are obligate aerobes able to oxidize ethanol, sugar alcohols, and sugars into their corresponding acids. Among them, Acetobacter and Gluconacetobacter species have very high ethanol oxidation capacity, leading to accumulation of vast amounts of acetic acid outside the cell. Since these bacteria are able to grow in media with high concentrations of acetic acid, they must pos...

Objective To compare the clinical efficacy of ear drops containing acetic acid, corticosteroid and acetic acid, and steroid and antibiotic in acute otitis externa in primary care. Design Randomised controlled trial. Setting 79 general practices, Netherlands. Participants 213 adults with acute otitis externa. Main outcome measures Primary outcome: duration of symptoms (days) according to patient...

objective: anti-inflammatory, immuno-modulatory, and antioxidant properties of moringa oleifera lam. suggest that it might have beneficial effects on colitis. the present study was performed to investigate the anticolitis effect of moringa oleifera seeds hydro-alcoholic extract (mshe) and its chloroform fraction (mcf) on acetic acid-induced colitis in rats. materials and methods: both mshe and ...

zno thin film of 80 nm thickness was deposited by the sol-gel spin coating method on sio2/si substrate and subsequently post-annealed at 500°c with a flow of oxygen for 60 min. crystallographic structure of the sample was characterized by x-ray diffraction (xrd) method while a field emission scanning electron microscope (fesem) was used to investigate the surface physical morphology and chemica...
