The effect of dietary feeding of hydroxyethyl methylcellulose (HEMC) and hydroxypropyl methylcellulose (HPMC) on the glucose metabolism and antioxidative status in mice under high fat diet conditions was investigated. The mice were randomly divided and given experimental diets for six weeks: normal control (NC group), high fat (HF group), and high fat supplemented with either HEMC (HF+HEMC grou...

The interaction of water with polymers is important because it directly or indirectly affects various properties such as rheological and transport properties. In this study, the hydration/dissolution of a hydrophilic polymer was investigated by calorimetric techniques. Hydroxypropyl methylcellulose E5 (Methocel, HPMC E5) was used as the model polymer. A water-insoluble, hydrophobic polymer, eth...

The title compound, Sr0.6Ba0.4Nb2O6 (strontium barium niobium oxide), belongs to the group of strontium-barium niobates with varying composition of Sr and Ba. Their general formula can be written as Sr x Ba1 - x Nb2O6. Below the Curie temperature, T c , these materials indicate ferroelectric properties. The Curie temperature for SBN60 is equal to 346±0.5 K so the structure is in the ferroelectr...

Background The aim of this study was to prepare and evaluate the impact of polymers on fabricating stable dexibuprofen (Dexi) nanocrystals with enhanced therapeutic potential, using a low energy, anti-solvent precipitation method coupled with molecular modelling approach. Methods Dexi nanocrystals were prepared using antisolvent precipitation with syringe pump. Crystallinity of the processed ...

A histone deacetylase (HDAC) inhibitor, suberoylanilide hydroxamic acid (SAHA), induces apoptosis in neoplastic cells, but its effect on gap junctional intercellular communication in relation to apoptosis was unclear. Therefore, we carried out a comparative study of the effects of two HDAC inhibitors, SAHA and trichostatin-A, on gap junctional intercellular communication in nonmalignant human p...

This Part II paper describes the disintegration and dissolution aspects of the qualification of a new hypromellose capsule (HPMC Shell 2). This new capsule does not contain any gelling agent, and is manufactured by a thermal gelation process. Rupture time of the carrageenan-containing capsule (HPMC Shell 1) and HPMC Shell 2, as measured by an improved real-time detection method, showed only sli...

The crystal structure of chloranilic acid, C(6)H(2)Cl(2)O(4), was first described by Andersen in 1967 [Andersen, E. K. (1967). Acta Cryst. 22, 188-191] at room temperature using visually estimated intensities. Taking into account the importance of the title compound, we have redetermined the structure at 100 (1) K. The approximately planar mol-ecule [the maximum deviation from the mean plane th...

Of key motivation in the development of detector strategies in the search for Weakly Interacting Massive Particles (WIMPs) is the need to maximize the information obtainable from the expected elastic recoil events so that these can be distinguished from background interactions and systematic errors can be controlled. Low temperature techniques may provide one route. However, most of the detecto...

STRUCTURAL STUDIES OF THE TITLE COMPOUND [SYSTEMATIC NAME: 2,2'-(disulfanedi-yl)dianiline], C(12)H(12)N(2)S(2), were previously performed at room temperature [Gomes de Mesquita (1967 ▶). Acta Cryst.23, 671; Lee & Bryant (1970 ▶). Acta Cryst. B26, 1729; Ribar et al. (1975 ▶). Bull. Yugoslav. Crystallogr. Centre, A10, 68]. The results of the current redetermination allow a clarification of the na...
