UNLABELLED The incidence and prevalence of gastroenteropancreatic neuroendocrine tumors has been increasing over the past 3 decades. Because of high densities of somatostatin receptors (sstr)--mainly sstr-2--on the cell surface of these tumors, (111)In-diethylenetriaminepentaacetic acid-octreotide scintigraphy has become an important part of clinical management. (18)F-radiolabeled analogs with ...

We demonstrate a fast response photo-inverter comprised of one transparent gated ZnO nanowire field-effect transistor (FET) and one opaque FET respectively as the driver and load. Under ultraviolet (UV) light the transfer curve of the transparent gate FET shifts to the negative side and so does the voltage transfer curve (VTC) of the inverter. After termination of UV exposure the recovery of ph...

Afm&act — We present a novel approach to nonlinear large-signaf FET model parameter extraction for GaAs MESFET devices measured under large-signaf condkions. Powerful nonlinear adjoint-based optimizatio~ which employs the harmonic bafance method as the nonlinear circuit simulation technique, simultaneously processes mrdtibias, yultipower inputs, mnki-fundamental-frequency excitations, and mnfti...

Utilizing the coupled piezoelectric and semiconducting dual properties of ZnO, we demonstrate a piezoelectric field effect transistor (PE-FET) that is composed of a ZnO nanowire (NW) (or nanobelt) bridging across two Ohmic contacts, in which the source to drain current is controlled by the bending of the NW. A possible mechanism for the PE-FET is suggested to be associated with the carrier trap...

This paper presents different techniques of one bit Full adder. In every technique the main requirements are power consumption, speed and power delay product. The proposed FIN-FET technique gives the bette.r power consumption, speed and power delay product than other techniques. The proposed Fin-FET technique is compared with some of the popular adders based on the power consumption, speed and ...

Background: Currently, frozen embryo transfers contribute an increasing rate of births from assisted reproductive technologies such as in vitro fertilization (IVF). However, very few studies evaluated the neonatal outcomes from frozen embryo transfer. This study aimed to investigate and compare the neonatal outcomes from frozen embryo transfer versus fresh embryo transfers. Materials and Method...

We present a technique for the label-free detection and recognition of cancer biomarkers using metal nanoislands intended to be integrated in a novel type of nanobiosensor. His-tagged (scFv)-F7N1N2 is the antibody fragment which is directly immobilized, by coordinative bonds, onto ~5 nm nickel islands, then deposited on the surface of a quartz crystal of a quartz crystal microbalance (QCM) to v...

background: natural endometrium in frozen-thawed embryo transfer (fet) may have some benefits upon implantation in patients with repeated implantation failure (rif). it might be due to possible differences between natural and stimulated endometrial growth factors and cytokins secretions. objective: the objective of this study was to compare the pregnancy rate of fet on modified natural cycle ve...

The breathing pattern of 399 patients with hyperventilation syndrome (HVS) and/or with anxiety disorders and that of 347 normal controls was investigated during a 5 min period of quiet breathing and after a 3 min period of voluntary hyperventilation. The diagnosis of HVS was based on the presence of several suggestive complaints occurring in the context of stress, and reproduced by voluntary hy...

UNLABELLED The aim of this study was to determine the spatial correlation of O-(2-(18)F-fluoroethyl)-L-tyrosine ((18)F-FET) uptake and the concentrations of choline (Cho), creatine (Cr), and total N-acetylaspartate (tNAA) determined with proton magnetic resonance spectroscopic imaging ((1)H MRSI) in cerebral gliomas for the multimodal evaluation of metabolic changes. METHODS (18)F-FET PET and...
