The concentrations of nonylphenol (NP), nonylphenol ethoxylates (NPnEOs: n = 1-15) and nonylphenoxy acetic acids (NPmECs: m = 1-10) in river water and sediment were determined seasonally at four sampling sites in the Kamo River, which is a typical urban river and was already known to be polluted by NP. In the water, the concentrations of NP, NPnEOs and NPmECs ranged from 0.13 to 3.65 microg/L, ...

Isobutyl-2 cyanoacrylate (IBCA) polymerizes by an anionic mechanism. The initiation of polymerization depends on an alkaline medium and can be inhibited with the addition of small amounts of acid. Using small amounts of glacial acetic acid (3.7%-7.1% by volume), the polymerization time was prolonged from 2.3 sec to 7.8 sec. In vivo experiments in dogs demonstrated no additional inflammatory rea...

The analgesic and anthelmintic activities of the common fruits in Sundarbans forest, Bangladesh were evaluated. Acetic acid-induced writhing test hot plate mice model demonstrated for examining activity whereas an was performed using a flatworm, Paramphistomum cervi livestock ruminants. Among fruits, Ceriops decandra showed strongest through inhibiting acetic (45%) increasing response time (16....

This study reports on the development and application of a fish-specific estrogen-responsive reporter gene assay. The assay is based on the rainbow trout (Oncorhynchus mykiss) gonad cell line RTG-2 in which an acute estrogenic response is created by cotransfecting cultures with an expression vector containing rainbow trout estrogen receptor a complementary DNA (rtERalpha cDNA) in the presence o...

Synthesis of 2-(4-sec-butyl-phenyl)-propionic acid-pyrrolidin-2-ylcarbamoyl methyl ester with bio-isosteric concept for ibuprofen with enhancing anti-inflammatory potential. Ibuprofen on refluxing with 2-amino pyridine in chloroacetyl chloride in presence of glacial acetic acid gave 2-(4-sec-butyl-phenyl)-propionic acid-pyrrolidin-2-yl-carbamoyl methyl ester, which can be used as a prodrug for ...
