Long-term exposure and inhalation of odorous compounds from poultry manure can be harmful to farm workers and the surrounding residents as well as animals. The aim of the present study was to determine the cytotoxicity and IC50 values of common odorous compounds such as ammonium, dimethylamine, trimethylamine, butyric acid, phenol, and indole in the chick liver hepatocellular carcinoma cell lin...

A straightforward, sensitive, and quick spectrophotometric approach was created validated for the detection of Ciprofloxacin hydrochloride, Moxifloxacin Roxithromycin hydrochloride in pure form. These techniques were based upon fact that these antibiotics produced dark yellow ion pairs when combined with bromophenol blue. The binary complex universal buffer solution optimum pH values demonstrat...

OBJECTIVES AND BACKGROUND The objective of this study was to investigate the image quality-improving and heart rate-lowering effects of landiolol hydrochloride (a short-acting β1-adrenergic receptor blocker) on coronary computed tomography angiography (CCTA). During CCTA, β-adrenergic receptor blockers have been commonly used to lower heart rate and improve image quality. METHODS A total of 2...

DESCRIPTION Aloxi (palonosetron hydrochloride) is an antiemetic and antinauseant agent. It is a selective serotonin subtype 3 (5-HT3) receptor antagonist with a strong binding affinity for this receptor. Chemically, palonosetron hydrochloride is: (3aS)-2-[(S)-1-Azabicyclo [2.2.2]oct-3-yl]-2,3,3a,4,5,6-hexahydro-1oxo-1Hbenz[de]isoquinoline hydrochloride. The empirical formula is C19H24N2O.HCl, w...

Prior studies of the viscosity of the subunit proteoglycan obtained by dissociative extraction of bovine nasal septum cartilage suggested that the proteoglycan subunit molecule behaves as a rigid rod in aqueous solution over the range of 0.5 to 4.0 M guanidine hydrochloride. A more direct view of dimension and shape can be obtained from light-scattering and viscosity of bovine nasal cartilage p...

The aim of the investigation was research N-deacetyllappaconitine hydrochloride antiarrhythmic properties. It found that studied substance effective on cardiac arrhythmias model caused by aconitine hydrochloride, but does not act models calciume chlorideinduced and reperfusion ventricular fibrillation. compound is less toxic than comparison drug lappaconitine hydrobromide acts in lower doses ar...

The objective of this study was to determine the effect of povidone. hydroxypropyl methylcellulose, hydroxypropyl cellulose, lactose and magnesium stearate on the stability of quinapril hydrochloride. The applied HPLC method was validated by the following parameters: selectivity, precision, linearity and accuracy. Binary 1:4 mixtures of quinapril hydrochloride and selected excipients were stabl...

Cationic surfactant is a chemical substance used in hair conditioner, fabric softener and other household products. By investigating the relationship between the aquatic toxicity and the chemical structures of two types of mono alkyl cationic surfactants, alkyl trimethylammonium salts and alkyl dimethylamine salts, we have found that the C22 alkyl chain length is effective to reduce the toxicit...

Dimethylamine, methylamine, propylamine, and pyrrolidine were the major amines formed by Bacteroides fragilis NCDO 2217 during the active phase of growth in batch culture. Production of these metabolites was strongly pH dependent and was optimal under acidic conditions (pH 6.0). Low pH also favored the formation of pyrrolidine, cadaverine, and dimethylamine by Clostridium perfringens C523, but ...
