Venkata V V R Marada et al.
Pharmacological research, 91, 78-87 (2014-12-08)
The ability of an antineoplastic drug to exert its cytostatic effect depends largely on the balance between its uptake into and extrusion from the cancer cells. ATP driven efflux transporter proteins drive the export of antineoplastic drugs and play a
Surya Prakash Rao Pydimarry et al.
Journal of chromatographic science, 52(7), 666-675 (2013-07-19)
A simple, sensitive and reproducible method was developed on ultra-performance liquid chromatography coupled with photodiode array detection for the quantitative determination of dronedarone hydrochloride (DRO) in drug substance and pharmaceutical dosage forms. The method is applicable for the quantification of
Robyn D Warner et al.
Meat science, 108, 155-164 (2015-07-15)
The aim of this experiment was to use metabolomic techniques to investigate the energy metabolism in lamb M. longissimus thoracis et lumborum subjected to very fast chilling (VFC) post-mortem. The tissue was prepared by 2 different operators and subjected to
Takeshi Hano et al.
Bulletin of environmental contamination and toxicology, 95(3), 340-343 (2015-04-24)
We evaluated the bioconcentration and elimination of polycarbamate, a popular antifoulant classified as a dithiocarbamate fungicide, in a marine teleost fish, mummichog (Fundulus heteroclitus), and a polychaete (Perinereis nuntia). Following polycarbamate exposure and depuration, the calculated bioconcentration factor (BCF) and
Jia Bao et al.
Environmental science and pollution research international, 21(12), 7650-7655 (2014-03-14)
Severe perfluoroalkyl acid (PFAA) contamination resulting from the fast-growing semiconductor, electrochemical, and optoelectronic industries has been determined in the river water in the vicinity of the Taipei area, Taiwan, during recent years. However, little is known about body burdens of
Melissa M St Amand et al.
Biotechnology and bioengineering, 111(10), 1957-1970 (2014-04-15)
N-linked glycan distribution affects important end-use characteristics such as the bioactivity and efficacy of many therapeutic proteins, (including monoclonal antibodies), in vivo. Yet, obtaining desired glycan distributions consistently during batch-to-batch production can be challenging for biopharmaceutical manufacturers. While an appropriately
Maria-Teresa Weichler et al.
Applied and environmental microbiology, 81(14), 4564-4572 (2015-04-26)
The recent discovery of a coenzyme B12-dependent acyl-coenzyme A (acyl-CoA) mutase isomerizing 3-hydroxybutyryl- and 2-hydroxyisobutyryl-CoA in the mesophilic bacterium Aquincola tertiaricarbonis L108 (N. Yaneva, J. Schuster, F. Schäfer, V. Lede, D. Przybylski, T. Paproth, H. Harms, R. H. Müller, and
Hongna Zhang et al.
Journal of chromatography. A, 1404, 72-80 (2015-06-14)
Degradation of fluorotelomer alcohols (FTOHs) was recognized as an additional source of perfluorocarboxylic acids (PFCAs). Quantification of FTOHs and their degradation products can help shed light on the sources and fates of PFCAs in the environment. In this study, an
Juan M Quiles et al.
Food and chemical toxicology : an international journal published for the British Industrial Biological Research Association, 83, 222-228 (2015-07-07)
Aflatoxins (AFs) are secondary metabolites produced by different species of Aspergillus, such as Aspergillus flavus and Aspergillus parasiticus, which possess mutagenic, teratogenic and carcinogenic activities in humans. In this study, active packaging devices containing allyl isothiocyanate (AITC) or oriental mustard
Muhammet Uyanik et al.
Science (New York, N.Y.), 345(6194), 291-294 (2014-07-19)
The diverse biological activities of tocopherols and their analogs have inspired considerable interest in the development of routes for their efficient asymmetric synthesis. Here, we report that chiral ammonium hypoiodite salts catalyze highly chemo- and enantioselective oxidative cyclization of γ-(2-hydroxyphenyl)ketones
Hiroyuki Nakao et al.
Biochimica et biophysica acta, 1848(1 Pt A), 145-150 (2014-10-15)
KcsA is a pH-dependent potassium channel that is activated at acidic pH. The channel undergoes global conformational changes upon activation. We hypothesized that the open-close conformational changes of the transmem brane region could promote the flip-flop of phosphoiipids. Based on
Javier Gualix et al.
Purinergic signalling, 10(2), 349-356 (2013-08-15)
Diadenosine triphosphate (Ap(3)A), diadenosine tetraphosphate (Ap(4)A), and diadenosine pentaphosphate (Ap(5)A) have been identified in microdialysis samples from the cerebellum of conscious freely moving rats, under basal conditions, by means of a high-performance liquid chromatography method. The occurrence of Ap(3)A in
K M Frankowski et al.
Journal of dairy science, 97(9), 5356-5370 (2014-07-16)
Many food companies are trying to limit the amount of sodium in their products. Permeate, the liquid remaining after whey or milk is ultrafiltered, has been suggested as a salt substitute. The objective of this study was to determine the
Haji Bahadar et al.
Environmental toxicology and pharmacology, 39(3), 1161-1169 (2015-05-04)
Benzene (C6H6) is an organic compound used in petrochemicals and numerous other industries. It is abundantly released to our environment as a chemical pollutant causing widespread human exposure. This study mainly focused on benzene induced toxicity on rat pancreatic islets
Huanhuan Zhang et al.
Environmental toxicology and chemistry, 34(7), 1499-1504 (2015-03-17)
Analytical methods for determining perfluoroalkyl acids (PFAAs) in leaves were developed to quantify a suite of analytes in both coniferous and deciduous broad-leaved trees. Sodium hydroxide-methanol and solid-phase extraction was selected as the extracting and cleanup strategy for PFAA analysis.
