BACKGROUND AND THE PURPOSE OF THE STUDY Technetium-99m is the major radionuclide used in the world and mainly is provided by fission product. However extensive research has been conducted on the use of accelerators for production of (99m)Tc. This investigation reports the production of (99m)Tc radioisotope using cyclotrons and the preparation, quality control and biodistribution studies of four...

I briefly review several key issues in understanding the cuprate superconductors from the point of view of doped-Mott-insulator. Then I present an effective low-energy theory and show that the phase diagram of such a model includes an anti-ferromagnetic (AF) phase, a superconducting state, and a pseudogap phase at low doping and low temperature, consistent with the experimental one. The dual to...

How to enhance the superconducting critical temperature (Tc) has been a primary issue since the discovery of superconductivity. The highest Tc reported so far is 166 K in HgBa2Ca2Cu3O8+δ (Hg1223) at high pressure of 23 GPa, as determined with the reduction onset, but not zero, of resistivity. To clarify the possible condition of the real maximum Tc, it is worth revisiting the effects of pressur...

We report first-principles calculations of the structures and properties of technetium nitride phases within the framework of gradient-corrected density functional theory. Specifically, we have investigated the possible existence of hexagonal Tc(3)N and Tc(2)N subnitrides, following the recent discovery of Re nitrides analogues synthesized directly from the elements. These novel Tc subnitride p...

UNLABELLED Reliable assessment of hepatic function during liver regeneration is crucial after liver surgery or liver transplantation. (99m)Tc-galactosyl human serum albumin ((99m)Tc-GSA) scintigraphy, (99m)Tc-mebrofenin hepatobiliary scintigraphy (HBS), the indocyanine green (ICG) clearance test, and the galactose elimination capacity (GEC) are common quantitative liver function tests. However,...

(99m)Tc-HYNIC-annexin A5 can be considered as a benchmark in the field of apoptosis imaging. However, (99m)Tc-HYNIC-annexin A5 has characteristics of high uptake and long retention in non-target tissues such as kidney and liver. To minimize this problem, we developed a novel (99m)Tc-labeled annexin A5 using a bis(hydroxamamide) derivative [C3(BHam)2] as a bifunctional chelating agent, and evalu...

H umanoid robotics is an emerging and challenging research field that has received significant attention during the past years and will continue to play a central role in robotics research and many applications of the 21st century. Regardless of the application area, one of the common problems dealt with in humanoid robotics is the understanding of humanlike information processing and the under...

(+)-Tubocurarine (TC) decreases the probability that the protozoan, Stentor coeruleus Ehrenberg, will contract in response to mechanical stimulation, because it selectively depresses mechanoreceptor currents. Resting membrane properties and action potentials are not significantly altered by the drug. Stentor incubated in media containing radioactively labelled TC (TC*) retain TC* after extensiv...

Recombinant human transcobalamin (TC) was probed with 17 monoclonal antibodies (mAbs), using surface plasmon resonance measurements. These experiments identified five distinct epitope clusters on the surface of holo-TC. Western blot analysis of the CNBr cleavage fragments of TC allowed us to distribute the epitopes between two regions, which spanned either the second quarter of the TC sequence ...
