The human α(1)/His(10)-β(1) isoform of the Na,K-ATPase has been expressed in Pichia pastoris, solubilized in n-dodecyl-β-maltoside, and purified by metal chelate chromatography. The α(1)β(1) complex spontaneously associates in vitro with the detergent-solubilized purified human FXYD1 (phospholemman) expressed in Escherichia coli. It has been confirmed that(More)
The use of wireless sensor networks (WSNs) has grown enormously in the last decade, pointing out the crucial need for scalable and energy-efficient routing and data gathering and aggregation protocols in corresponding large-scale environments. To maximize network lifetime in Wireless Sensor Networks (WSNs) the paths for data transfer are selected in such a(More)
Effect of chamber pressure on liquid drop impacts on a stationary smooth and dry surface. ii ACKNOWLEDGEMENTS I would like to thank the Graduate College, University of Iowa, for giving me this chance to pursue a Master's degree at this university. Many thanks are due also to Prof. whose constant guidance, support and encouragement were extremely important(More)
This paper proposed an automated system for grading of colorectal cancer using image processing method. Almost, half a million people die every year due to colon cancer. Histopathological tissue analysis is a common method for its detection, which needs an expert pathologist. Screening for this cancer is effective for prevention as well as early detection.(More)
FXYD proteins are a family of seven small regulatory proteins, expressed in a tissue-specific manner, that associate with Na,K-ATPase as subsidiary subunits and modulate kinetic properties. This study describes an additional property ofFXYD proteins as stabilizers ofNa,K-ATPase. FXYDI (phospholemman), FXYD2 (y subunit), and FXYD4 (CHIF) have been expressed(More)
The Teeter Toy provides a simple yet effective and interesting example for understanding modeling of dynamics of a rigid body system, from the view point of generalized forces, representation of different forms of energy, stability etc. In this paper, the dynamics of the Teeter toy is modeled using multibond graph. Constraints have also been taken into(More)
The purpose of this work is to present ongoing development of a test rig to understand the participation of each tendon of the human finger during a task. Both flexion and extension of the finger are considered. For the extensor mechanism, tendon topology as in the Winslow rhombus tendon topology is considered. For flexor, two tendons are explicitly used.(More)
