A novel method is proposed using nanometer-sized diamond particles as detection probes for biolabeling. The advantages of nanodiamond's unique properties were demonstrated in its biocompatibility, nontoxicity, easily detected Raman signal, and intrinsic fluorescence from its natural defects without complicated pretreatments. Carboxylated nanodiamond's (cND's) penetration ability, noncytotoxicit...

BACKGROUND Our aim was to assess the safety and efficiency of operating microscope use by surgeons in thyroid surgery to reduce static neck flexion. METHODS A retrospective case review comparing thyroidectomies performed using an operating microscope to those using surgical loupes was done. Operative times and incidence of complications were compared between total thyroidectomy procedures don...

Purpose The aim of this study is to investigate the predictive value of BRAF V600E mutation for the persistence of papillary thyroid cancer (PTC) after total thyroidectomy and routine central neck dissection. Patients and Methods We collect the clinicopathological data of 288 PTC patients with total thyroidectomy (TT) and routine central neck dissection (CND), and analyzed the relationship betw...

VLA maps of ammonia emission were made for the Galactic Center region. The NH3(1,1) and NH3(2,2) transitions were observed in three 2 ×2 fields covering Sgr A and the region 3 immediately south of it. In the central 3 parsecs surrounding Sgr A we find emission which appears to be associated with the circumnuclear disk (CND), both morphologically and kinematically. This central emission is conne...

OBJECTIVE To assess risk factors for chronic noncommunicable disease (CND) and to identity social inequalities in their distribution among the adult Brazilian population. METHODS Study of CND risk factors (including tobacco use, overweight and obesity, low fruit and vegetable intake (LFVI), insufficient leisure-time physical activity (LTPA), sedentary lifestyle, and alcohol abuse, among other...

We describe an implicit prediction of the accretion disk models constructed by Wardle and Königl (1990) for the circumnuclear disk (CND) of gas and dust near the Galactic center: supersonic ambipolar diffusion, an essential dynamical ingredient of the Wardle-Königl disks, will cause the alignment of dust grains due to a process described by Roberge, Hanany, & Messinger (1995). We calculate synt...

We present high resolution H41 hydrogen recombination line observations of the 1 2 (3 pc) region surrounding Sagittarius A (Sgr A ) at 92 GHz using the Millimeter Array at the Owens Valley Radio Observatory (OVRO) with an angular resolution of 7 3 and velocity resolution of 13 km s−1. New observations of H31 , H35 , H41 and H44 lines were obtained using the NRAO 12-m telescope, and their relati...

OBJECTIVE To determine the risk of nodal metastases to the central compartment from differentiated papillary thyroid carcinoma (PTC) relative to known prognostic variables. DESIGN A 7-year single-institutional retrospective review. SETTING Tertiary academic center. PATIENTS A total of 115 patients undergoing central neck dissection (CND) for PTC or follicular variant PTC (FVPTC). MAIN O...

Low-density parity-check (LDPC) codes are very powerful error-correction codes with capabilities approaching the Shannon’s limits. In evaluating the error performance of a LDPC code, the computer simulation time taken becomes a primary concern when tens of millions of noise-corrupted codewords are to be decoded, particularly for codes with very long lengths. In this paper, we propose modeling t...
