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 ...

This work introduces three novel chaotic map circuits. Two of the circuit use two p -channel and one xmlns:xlink="http://www.w3.org/1999/xlink">n silicon-on-insulator (SOI) four-gate transistor (G 4 FET) while third design uses G FET. Th...

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...

Two-dimensional (2D) semiconductor materials have attracted broad interest due to their unique structures and physical properties. The stability of the 2D-material-based devices plays a key role in their practical applications. Here, we report the promising stable electrical performance in the large-scale monolayer WSe2(1-x)S2x with a tunable band gap. Photoluminescence (PL) spectroscopy was ut...

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...

This paper presents a simple behavioral model with experimentally extracted parameters for packaged cascode gallium nitride (GaN) field-effect transistors (FETs). This study combined a level-1 metal–oxide–semiconductor field-effect transistor (MOSFET), a junction field-effect transistor (JFET), and a diode model to simulate a cascode GaN FET, in which a JFET was used to simulate a metal-insulat...

The chapter highlights selected electric charge transport phenomena studied recently in low dimensional structures of DMSs. The first part describes transport phenomena related to the quantum interference of scattered electron waves in diffusive transport regime at the boundary of metalinsulator transition. The second part is devoted to Landau quantization of electronic states, as quantum Hall ...

UNLABELLED PET using O-(2-(18)F-fluoroethyl)-L-tyrosine ((18)F-FET) provides important diagnostic information in addition to that from conventional MR imaging on tumor extent and activity of cerebral gliomas. Recent studies suggest that perfusion-weighted MR imaging (PWI), especially maps of regional cerebral blood volume (rCBV), may provide similar diagnostic information. In this study, we dir...

Electron micrographs of CCL237 and FET cells (two slowly growing, differentiated human colon carcinoma lines) revealed enlarged mitochondria with few cristae. Polarographic measurement of respiratory activity in mitochondria isolated from these cell lines was compared to that of CV-1 cells (a normal monkey kidney epithelial line) and MIP101 cells (another human colon carcinoma line), both of wh...

Noninvasive tumor growth monitoring is of particular interest for the evaluation of experimental glioma therapies. This study investigates the potential of positron emission tomography (PET) using O-(2-(18)F-fluoroethyl)-L-tyrosine ([(18)F]-FET) to determine tumor growth in a murine glioblastoma (GBM) model-including estimation of the biological tumor volume (BTV), which has hitherto not been i...
