“Detection of small concentrations of sub-200-nm-sized SPBs (superparamagnetic beads with sizes similar to target molecules) used as ‘magnetic labels’ is critical for the development of rapid, highly sensitive, and portable point

of care treatment (POCT) systems. Currently, magnetoresistive (MR) biosensors are used for the detection of large concentrations of SPBs but such an approach is not suitable for monitoring small numbers of sub-200-nm SPBs due to the intrinsic noise of these electronic SN-38 ic50 devices. In order to overcome this limitation of conventional MR sensors, we have developed a simple procedure Alvespimycin price for detecting small concentrations of sub-200-nm-diameter SPBs for biosensing by exploiting magnetically induced self-assembly of micrometer-sized SPBs onto nanometer targets. Here, our approach enables the physical amplification of the signal from otherwise undetectable nano-SPB targets using Hall biosensors without using the application of ac, magnetic fields or lock-in detection, thereby

enabling the production of a simple POCT protocol for a wide range of applications. (C) 2011 American Institute of Physics. [doi:10.1063/1.3556957]“
“The aim of this study was to investigate serum fetuin-A, coenzyme Q(10) and plasma fatty acids profiles in obese and healthy subjects. Subjects & Methods: The study was performed on a total of 105 obese subjects (22 male and 83 female) aged 38.3 +/- 12.9 years and 80 healthy subjects (20 male and 60 female) aged 36.3 +/- 11.3 years. Plasma fatty acid composition was measured by gas chromatography-mass spectrometry, serum coenzyme Q(10) level was measured by high-performance liquid chromatography and serum fetuin-A level was measured by ELISA methods. Results: Plasma myristic acid, palmitic acid, palmitoleic acid, 10c-heptadecanoic

acid, linoleic acid, heneikosanoic acid, saturated fatty acids levels and Delta 9-desaturase activity of the obese subjects were significantly find more higher (p < 0.05), whereas behenic acid levels and elongase activity were significantly lower (p < 0.05) than the same parameters in the controls. There were no significant differences between plasma monounsaturated fatty acids, polyunsaturated fatty acids, serum coenzyme Q(10) and fetuin-A levels in either of the groups. Discussion: Our results demonstrate that plasma saturated fatty acid levels of obese subjects were significantly increased. Also, the plasma levels of some fatty acids and enzyme activities of both groups were significantly different from each other. The role of these findings in the development of obesity needs to be investigated further.
