Fixation is a critical step in the preparation of tissues for histopathology. The objective of this study was to investigate the effects of different fixatives vs formalin on proteins and DNA, and to evaluate alternative fixation for morphological diagnosis and nucleic acid preservation for molecular methods. Forty tissues were fixed for 24 h with six different fixatives: the gold standard fixa...

The aim of the present study was to investigate the effects of size-fractionated (i.e., <1; 1-2.5, and 2.5-10 µm in an aerodynamic diameter) ambient particulate matter (PM) on reactive oxygen species (ROS) activity and cell viability in human bronchial epithelial cells (BEAS-2B). The PM samples were collected from an urban site (uPM) in Beijing and a steel factory site (sPM) in Anshan, China, f...

The recommended policy-based management system by the IETF is a two-tiered architectural design. It exhibits several observable fundamental limitations, for example, system scalability and cross-vendor hardware compatibility problems. In this article, a multitiered architecture, the unified policy-based management system, is proposed. The middle-tier agents, introduced between policy managers a...

For the past decade, the field of Bacteriorhodopsin (BR) research has been influenced by a kinetic view of the photocycle as a reversible, homogeneous, model (RHM) with a linear sequence of intermediates. More recently, we proposed a much different model which consists of essentially unidirectional, parallel (i.e., heterogeneous) cycles (UPM) (Hendler, R. W.; Shrager, R. I.; Bose, S. J. Phys. C...

We describe a new control method for vibrationsbased planar manipulation. We’ve developed a device – the Universal Planar Manipulator (UPM) – based on a single, horizontally-vibrating plate. Though minimalist in construction (one moving part), the UPM can manipulate several parts on its surface in parallel, simply using friction. Previously, we’ve shown that a sequence of rigid plate rotations ...

Besides providing network management to the Internet, it has become essential to offer different Quality of Service (QoS) to users. Policy-based management provides control on network routers to achieve this goal. The Internet Engineering Task Force (IETF) has proposed a two-tier architecture whose implementation is based on the Common Open Policy Service (COPS) protocol and Lightweight Directo...
