BACKGROUND The subtype distribution of lymphoid neoplasms in Southwest China was analyzed according to WHO classifications. This study aims to analyze subtype distribution of lymphomas in southwest China. METHODS Lymphoid neoplasms diagnosed within 9 years in a single institution in Southwest China were analyzed according to the WHO classification. (More)
The problem of missing link prediction in complex networks has attracted much attention recently. Two difficulties in link prediction are the sparsity and huge size of the target networks. Therefore, to design an efficient and effective method is of both theoretical interest and practical significance. In this letter, we proposed a method based on local(More)
To estimate the distribution of lymphoid neoplasms in China, we conducted a comprehensive analysis, based on subtype, age, sex, and lesion, of primary and resected biopsy specimens of 4,638 lymphoid neoplasms diagnosed from 2004 to 2008 at 5 large hospitals. Of the 4,638 patients, mature B-cell neoplasms accounted for 64.3% of all lymphoid neoplasms, mature(More)
Anaerobic ammonium-oxidizing (anammox) bacteria have been detected in many marine and freshwater ecosystems. However, little is known about the distribution, diversity, and abundance of anammox bacteria in terrestrial ecosystems. In this study, anammox bacteria were found to be present in various agricultural soils collected from 32 different locations in(More)
PURPOSE To investigate the role of early or up-front radiotherapy (RT), the optimal RT dose required to achieve appropriate treatment outcome and prognostic factors for patients with localized extranodal NK/T-cell lymphoma, nasal-type, in the upper aerodigestive tract. METHODS AND MATERIALS Eighty-two patients were reviewed. Eight patients were treated(More)
Atrazine (ATZ) is the most common pesticide of freshwater ecosystems in the world. The effects of ATZ exposure on the induction of oxidative stress and the alteration of gene expression were studied in liver and ovary samples from female zebrafish (Danio rerio). Antioxidant enzyme activities (SOD and CAT), in addition to the GSH and MDA content, in the(More)
Algal blooms have been increasing in prevalence all over the world, destroying ecosystems and placing other organisms at risk. Chemical remediation is one of most important methods of controlling algal bloom formation. The effects of copper sulfate, hydrogen peroxide (H(2)O(2)) and N-phenyl-2-naphthylamine on photosynthesis-related and microcystin-related(More)
Simple spring-damper-mass models have been widely used to simulate human locomotion. However, most previous models have not accounted for the effect of non-rigid masses (wobbling masses) on impact forces. A simple mechanical model of the human body developed in this study included the upper and lower bodies with each part represented by a rigid and a(More)
Traumatic brain injury (TBI) is a leading cause of mortality and disability among the young population. It has been shown that hydrogen gas (H(2)) exerts a therapeutic antioxidant activity by selectively reducing hydroxyl radical (OH, the most cytotoxic ROS). Recently, we have found that H(2) inhalation significantly improved the survival rate and organ(More)
BACKGROUND Extranodal natural killer/T-cell lymphoma (ENKTL), nasal-type, is a distinct entity of lymphoid tissue. ENKTL is sensitive to radiotherapy (RT), but the prognosis is poorer than for other types of early lymphoma. The treatment schedule is controversial. METHODS A phase 2 study was conducted of "sandwich" protocols, with earlier RT after an(More)
