introduction: hemangiomas are the most frequent benign tumors of the liver and detecting them from metastasis or other malignant hepatic tumors is of outmost importance. 99mtc- rbc scan is highly specific and is the method of choice for this differentiation. this scintigraphy is performed in planar and spect modes. these two procedures are in agreement most of the times, however since spect is ...

Abstract It has become increasingly evident that even though B cells respond to both soluble and membrane-presented antigens in vitro, the primary mode of antigen recognition vivo appears be on surfaces antigen-presenting cells. To determine how sense an is membrane associated, we investigated role Piezo1 mechanosensing cation channel human B-cell activation. We discovered flux calcium when sim...

Here we present a planar patch clamp chip based on biomimetic cell membrane fusion. This architecture uses nanometer length-scale surface patterning to replicate the structure and function of membrane proteins, creating a gigaohm seal between the cell and a planar electrode array. The seal is generated passively during cell spreading, without the application of a vacuum to the cell surface. Thi...

this paper is dedicated to propose an algorithm in order to generate the certain isomers of some well-known fullerene bases. furthermore, we enlist the bipartite edge frustration correlated with some of symmetrically distinct innite families of fullerenes generated by the oered process.

Cells expressing the E1 and E2 envelope proteins of Semliki Forest virus (SFV) were fused to voltage-clamped planar lipid bilayer membranes at low pH. Formation and evolution of fusion pores were electrically monitored by capacitance measurements, and membrane continuity was tracked by video fluorescence microscopy by including rhodamine-phosphatidylethanolamine in the bilayer. Fusion occurred ...

Transfer printing integration of planar membrane devices on photonic and electronic circuits is becoming a well established technology. Typical systems incorporate single layer printed into full contact with the host substrate. In this work we present an advanced transfer print system that enables optical in non-planar geometries allows in-situ monitoring devices. We show micro-resonators air-c...

Electrochemical pressure impedance spectroscopy (EPIS) has recently been developed as a potential diagnosis tool for polymer electrolyte membrane fuel cells (PEMFC). It is based on analyzing the frequency response of cell voltage with respect to an excitation gas-phase pressure. We present here combined modeling and experimental study EPIS. A pseudo-two-dimensional PEMFC model was parameterized...
