In this clinical study, we have compared routine diagnostic dose (131)I scan and (99m)TcO4(-) thyroid scintigraphy with therapeutic dose (131)I imaging for accurate thyroid remnant estimation after total thyroidectomy. We conducted a retrospective review of the patients undergoing total thyroidectomy for differentiated thyroid carcinoma (DTC) and subsequently receiving radioactive iodine (RAI) ...

The binding and metabolism of [3H]vitamin A-containing chylomicron (CM) remnants by the human hepatoma cell line HepG2 were studied. Mesenteric lymph chylomicrons were collected from [3H]retinol-fed rats and incubated with lipoprotein lipase to obtain CM remnants. At 4 degrees C, specific CM remnant binding was inhibited by an excess of unlabeled CM remnants. Specific binding predominated at lo...

A series of charge-balanced Si4+-M1+,2+ (M = Mg2+, K+, Li+) substitution compositions with the chemical formulae SrFe12−2xSixMgxO19 (x 0, 0.05, 0.1, 0.2), Sr1−yFe12−ySiyKyO19 (y and SrFe12−z(Si0.6Li0.6)zO19 (z 0.2, 0.4, 0.6) were prepared using conventional ceramic processes. While sole doping Si x 0.1 (SrFe12−xSixO19 0.1)) causes a noticeable Fe2O3 phase formation, co-doping Si-Mg Si-Li allow ...

Remnant tree presence affects forest recovery after slashand-burn agriculture. However, little is known about its effect on above-ground carbon stocks, especially in Africa. We focused our study on Sierra Leone, part of the Upper Guinean forests, an important centre of endemism threatened by encroachment and forest degradation. We studied 99 (20-m-radius) plots aged 2–10 years with and without ...

BACKGROUND It remains undetermined whether triglyceride-rich lipoproteins are an independent risk factor for atherosclerosis. METHODS AND RESULTS The correlation of responses of coronary arterial diameter (quantitative coronary angiography) and coronary blood flow (intracoronary flow wire technique) to intracoronary infusion of acetylcholine (10 and 50 microg/min) with coronary risk factors i...

We model the intermediate time evolution of a “jetted” gamma-ray burst by two blobs of matter colliding with the interstellar medium. We follow the hydrodynamical evolution of this system numerically and calculate the bremsstrahlung and synchrotron images of the remnant. We find that for a burst energy of 10 erg the remnant becomes spherical after ∼ 5000 years when it collects ∼ 50M⊙ of interst...

Magnetization reversal of uniaxial Stoner particles under the Slonczewski spin-transfer torques of polarized electric currents is investigated. Based on the modified Landau-Lifshitz-Gilbert equation of magnetization dynamics, the theoretical limit of critical currents required to reverse a magnetization with an arbitrary polarized current is obtained. Under a constant polarization degree and co...

We use two-dimensional hydrodynamical simulations to investigate the properties of dense ejecta clumps (bullets) in a core collapse supernova remnant, motivated by the observation of protrusions probably caused by clumps in the Vela supernova remnant. The ejecta, with an inner flat and an outer steep power law density distribution, were assumed to freely expand into an ambient medium with a con...
