BACKGROUND: Contact dermatitis to cosmetics is a common dermatosis, especially in adults and professionals who handle them. OBJECTIVE: The objective of this study was to evaluate the frequency of sensitization to cosmetics ́ components in patients with suspected allergic contact dermatitis and to identify the main sensitizers related to occupational contact dermatitis. METHODS: During the period...

Suspended particles in water are a major concern in global pollution management. They affect the appreciation of water due to clarity, photosynthesis, and poor oxygen environment rendering water unsuitable for aquatic animals. Some suspended materials contain functional groups capable of forming complex compounds with metals making them available for poisoning. Such material promotes the growth...

New Cr–Fe–Ln complexes with ferrocenecarboxylate and triethanolamine ligands are obtained. Tb, Dy Ho SMMs, one has the anisotropy barrier of 75 K. Thermolysis leads to Cr 0.75 Fe 1.25 O 3 LnCr 0.25 phases.

Capillary zone electrophoresis was applied for the determination of amphetamine and related substances in seized drugs. A buffer made of 0.1 M phosphoric acid adjusted to pH 3.0 with triethanolamine was selected. With this background electrolyte, triethanolamine is adsorbed to the capillary wall and the electroosmotic flow is reversed. This gives rise to peaks with good symmetry, high efficienc...

Triethanolamine (TEA) is converted into acetate and ammonia by a strictly anaerobic, gram-positive Acetobacterium strain LuTria3. Fermentation experiments with resting cell suspensions and specifically deuterated substrates indicate that in the acetate molecule the carboxylate and the methyl groups correspond to the alcoholic function and to its adjacent methylene group, respectively, of the 2-...

Terbinafine Hydrochloride (TH) is a new potent antifungal agent. Several HPTLC, non-aqueous voltametric, spectrometric methods, ion-pair RP chromatography and Stability-indicating HPTLC methods have been published till now. The aim of the present study is to develop and validate simple, precise, specific and sensitive stability indicating reversed-phase HPLC (RP-HPLC) method for analysis of Ter...
