Assessment of benzene induced oxidative impairment in rat isolated pancreatic islets and effect on insulin secretion.

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

The role of sodium in the salty taste of permeate.

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

Perfluoroalkyl acids in blood serum samples from children in Taiwan.

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

pH-dependent promotion of phospholipid flip-flop by the KcsA potassium channel.

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

Identification of manipulated variables for a glycosylation control strategy.

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
