Preoperative screening for synchronous colorectal neoplasia (CRN) has been recommended in patients with gastric cancer because patients with gastric cancer are at increased risk for synchronous CRN. The aim of this study was to investigate the diagnostic accuracy of F-fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) for detecting synchronous advanced CRN in p...

Oligonucleosomal fragmentation of chromosomes in dying cells is a hallmark of apoptosis. Little is known about how it is executed or what cellular components are involved. We show that crn-1, a Caenorhabditis elegans homologue of human flap endonuclease-1 (FEN-1) that is normally involved in DNA replication and repair, is also important for apoptosis. Reduction of crn-1 activity by RNA interfer...

BACKGROUND To improve assessment of dystrophinopathy, the aim of this study was to identify whether serum creatinine (Crn) level reflects disease severity. METHODS Biochemical, Vignos score, and genetic data were collected on 212 boys with dystrophinopathy. RESULTS Serum Crn level had a strong inverse correlation with Vignos score by simple correlation (r = -0.793) and partial correlation a...

CONTEXT Cost-related medication nonadherence (CRN) has been a persistent problem for individuals who are elderly and disabled in the United States. The impact of Medicare prescription drug coverage (Part D) on CRN is unknown. OBJECTIVE To estimate changes in CRN and forgoing basic needs to pay for drugs following Part D implementation. DESIGN, SETTING, AND PARTICIPANTS In a population-level...

Mesoporous chromium nitride (CrN) was prepared by a solid-solid phase separation method and was further evaluated as a support for Pt in the oxygen reduction reaction (ORR). Pt/CrN exhibits higher electrocatalytic activity and stability than Pt/C toward the ORR, which may be attributed to the excellent electronic conductivity, and chemical and electrochemical stability of CrN. The fact that CrN...

Both singleand polycrystalline CrN layers are grown by reactive sputtering on MgO and quartz substrates, respectively. Temperature-dependent x-ray diffraction indicates a phase transition near 280 K to a low-temperature orthorhombic phase for polycrystalline CrN, while epitaxial constraints cause single-crystal CrN(001) and CrN(111) to remain in the cubic high-temperature phase. Electronic tran...

Phytophthora and other oomycetes secrete a large number of putative host cytoplasmic effectors with conserved FLAK motifs following signal peptides, termed crinkling and necrosis inducing proteins (CRN), or Crinkler. Here, we first investigated the evolutionary patterns and mechanisms of CRN effectors in Phytophthora sojae and compared them to two other Phytophthora species. The genes encoding ...

In this paper, we conduct a cross-layer analysis of both the jamming capability of the cognitiveradio-based jammers and the anti-jamming capability of the cognitive radio networks (CRN). We use a Markov chain to model the CRN operations in spectrum sensing, channel access and channel switching under jamming. With various jamming models, the jamming probabilities and the throughputs of the CRN a...

Patients, aged ≥ 50 years, with gastric neoplasm are reported to be at increased risk for colorectal neoplasia (CRN), while data regarding the risk of CRN in young patients, aged < 50 years with gastric neoplasm are limited. We aimed to investigate the risk of CRN according to the presence of gastric neoplasm in patients, aged < 50 years, and conducted a cross-sectional study on 131,888 asympto...
