BACKGROUND We describe a novel approach that harnesses the ubiquity of copy number deletion polymorphisms in human genomes to definitively detect and quantify chimeric DNA in clinical samples. Unlike other molecular approaches to chimerism analysis, the copy number deletion (CND) method targets genomic loci (>50 base pairs in length) that are wholly absent from wild-type (i.e., self) background...

OBJECTIVES/HYPOTHESIS To describe the clinical and audiometric characteristics of children with cochlear nerve dysplasia (CND). STUDY DESIGN Retrospective chart review of clinical database of children with inner ear anomalies treated at a tertiary care children's hospital. METHODS Institutional review board-approved retrospective review from June 30, 2006, to July 1, 2011; 18 children were ...

The goal of computer network defense (CND) is to protect the system and ensure the organization operates resiliently under strain [1]. To succeed, the CND strategy must plan for adversary response to defensive measures. Part of this planning is strategic management of equities. In the security field, the word equities has a special meaning: information assets that provide an advantage over the ...

BACKGROUND Central lymph node dissection (CND) has been proposed in the treatment of patients affected by papillary thyroid cancer (PTC) with clinically negative neck lymph nodes. The procedure allows pathologic staging of lymph nodes of the central compartment and treatment of the micrometastases. By comparing bilateral and unilateral thymectomy during total thyroidectomy with central lymph no...

Effective visual analysis of computer network defense (CND) information is challenging due to the volume and complexity of both the raw and analyzed network data. A typical CND is comprised of multiple niche intrusion detection tools, each of which performs network data analysis and produces a unique alerting output. The state-of-the-practice in the situational awareness of CND data is the prev...

In this study, a new reliable, economic, and environmentally-friendly one-step synthesis is established to obtain carbon nanodots (CNDs) with well-defined and reproducible photoluminescence (PL) properties via the microwave-assisted hydrothermal treatment of starch and Tris-acetate-EDTA (TAE) buffer as carbon sources. Three kinds of CNDs are prepared using different sets of above mentioned star...

OBJECTIVES This study aims to evaluate the effectiveness of selective neck dissection (SND) in stage pN1 head and neck cancers. PATIENTS AND METHODS Patients who underwent neck dissection due to squamous cell carcinoma of oral cavity, larynx, oro-hypopharynx were evaluated retrospectively. Sixty-one patients diagnosed with pathological N1 by neck dissection were included in the study. Thirty-...

Crop nitrogen is an efficient index for estimating crop yield. Using hyperspectral information to monitor in cotton real time can help guide cultivation. In this study, we used drip-irrigation Xinjiang as the research object and employed various treatments explore correlation between vegetation indexes leaf concentration (LNC) canopy density (CND) of different growth periods interannual. We 30 ...

Lymph node involvement is associated with recurrence in papillary thyroid carcinoma (PTC). The central neck compartment (level VI) lymph nodes are at the greatest risk of metastases from PTC, but the role of central neck dissection (CND) remains controversial, particularly in PTC without clinical cervical lymph node metastasis (cN0). The present study aimed to identify risk factors of central c...
