Seven races of Striga gesnerioides parasitic on cowpea, a major food and forage legume in sub-Saharan Africa, have been identified. Race-specific resistance of cowpea to Striga involves a coiled-coil nucleotide binding site leucine-rich repeat domain resistance protein encoded by the RSG3-301 gene. Knockdown of RSG3-301 expression by virus-induced gene(More)
Following the first human infection with the influenza A (H10N8) virus in Nanchang, China in December 2013, we identified two additional patients on January 19 and February 9, 2014. The epidemiologic, clinical, and virological data from the patients and the environmental specimen collected from 23 local live poultry markets (LPMs) were analyzed. The three(More)
BACKGROUND Human infections with different avian influenza viruses--eg, H5N1, H9N2, and H7N9--have raised concerns about pandemic potential worldwide. We report the first human infection with a novel reassortant avian influenza A H10N8 virus. METHODS We obtained and analysed clinical, epidemiological, and virological data from a patient from Nanchang(More)
In order to increase the speed of genetic watermarking and improve the robustness and imperceptibleness of the algorithm, a new embedding and extracting method with genetic algorithm (GA) was proposed. The AC coefficients of image in DCT domain were modified to embed the watermark. The proposed embedding and extracting method was employed to accelerate the(More)
On a local scale, invasiveness of introduced species and invasibility of habitats together determine invasion success. A key issue in invasion ecology has been how to quantify the contribution of species invasiveness and habitat invasibility separately. Conventional approaches, such as comparing the differences in traits and/or impacts of species between(More)
Transcriptional networks orchestrate complex developmental processes, and such networks are commonly instigated by master regulators for development. By now, considerable progress has been made in elucidating GATA factor-dependent genetic networks that control red blood cell development. Here we reported that GATA-1 and GATA-2 co-regulated the expression of(More)
BACKGROUND MicroRNAs act as posttranscriptional regulators of gene expression in many biological processes. Their deregulations occur commonly in gastric cancer (GC). Although DNA methylation constitutes an important mechanism for microRNA deregulation in cancer, this field largely remains unexplored. METHODOLOGY/PRINCIPAL FINDINGS Total RNA was extracted(More)
Type B influenza virus is one of the major epidemic strains and responsible for considerable mortality and morbidity. Rapidly and accurately identifying different influenza B virus lineages, i.e., B/Yamagata (B/Y) and B/Victoria (B/V), is desirable during the flu season. However, the available rapid techniques lack sensitivity, and the usual methods for(More)
In this paper, a passive RFID tag antenna in UHF band (860MHz-960MHz) using a meander split ring like a gear and an electricity small loop is proposed. Inductively coupled feed method is used to broaden the bandwidth. The proposed structure not only successfully reduces the tag size but also achieves impedance match between the antenna and the chip(More)
