In this study, we characterized a WRKY family member gene, SsWRKY1, which is located in the nucleus and contains multiple stress-related cis-acting elements. In addition, constructed SsWRKY1-overexpressing Arabidopsis thaliana had higher antioxidant enzyme activity and proline content under drought stress conditions, with lower malondialdehyde content and reactive oxygen species (ROS) accumulation, and the expression levels of six stress-related genes were significantly upregulated. This indicates that the overexpression of SsWRKY1 in Arabidopsis thaliana improves resistance to drought stress.

The utilization of restricted parents in breeding programs of modern cultivated sugarcane has resulted in a genetic blockage, which controlled its improvement because of the limited genetic diversity. The use of wild relatives is an effective way to broaden the genetic composition of cultivated sugarcane.

The morphology and crystal structure of the nanoparticles were studied by TEM/HRTEM and XRD. The nanoparticles manifest soft ferromagnetic and/or near superparamagnetic behavior with a small coercivity of ~19 Oe at room temperature.

In the comments, the authors raise a question whether the linear headache (LH) we reported be a linear interictal pain in epicranial fugax (EF), based on a case they reported. We think that the LH is not a linear interictal pain in EF based on our observations and considerations.

In a 25-month period from Feb 2012 to Mar 2014, we encountered 12 patients with a paroxysmal motionless head pain restricted in a linear trajectory. The head pain trajectory was similar to that of EF, but its all other features obviously different from those of EF.

The third cranial nerve is most commonly involved in the recurrent attacks. But it is still debated whether a migraine or an oculomotor neuropathy may be the primary cause of this disorder.

Objective: To develop a spatio-temporal model of schistosomiasis japonica based on Bayesian model, and to analyze the spatio-temporal pattern of schistosomiasis, as well as to evaluate the impact of environment changes on schistosomiasis endemic.
Methods: Different Bayesian models were established by employing the data of the periodical surveillance on schistosomiasis during 1996-2005 period by taking into account of the uncertainty in sensitivity and specificity of diagnostic test, then the best fitness model was selected to analyze the spatio-temporal pattern of schistosomiasis and evaluate the impact of environment changes on schistosomiasis.
Results: The model with space-time interaction was a better fitting model.

Objective: To study the expression of plasma membrane Ca(2+)-ATPase isoform 2 (PMCA2) in spiral ganglion cell (SGC) from inner ear of newborn rats and further check PMCA2 splice variants at site A and C.
Methods: Spiral ganglion tissues isolated from cochlea of newborn rats (P3-P4) were cultured and identified in vitro. The cochlea of newborn rats (P3-P4) were isolated and cut into frozen sections.
Detailed knowledge of how local landscape patterns influence the distribution of Oncomelania hupensis, the intermediate host snail of Schistosoma japonicum, might facilitate more effective schistosomiasis control. We selected 12 villages in a mountainous area of Eryuan County, Yunnan Province, People's Republic of China, and developed Bayesian geostatistical models to explore heterogeneities of landscape composition in relation to distribution of O. hupensis.

However, the available data suggested that schistosomiasis has re-emerged shortly after the World Bank Loan Project which was conducted from 1992 to 2001. The national control program with a revised strategy to control schistosomiasis by using integrated measures has been implemented since 2005.

Objective: To study the evaluation indices and their weights of social burden caused by advanced schistosomiasis so as to provide scientific basis for control of the disease.
Methods: Primary indices of social burden evaluation for advanced schistosomiasis were summarized based on literature review. Secondary indices were put forward by a brainstorming process of experts.
Background: Schistosoma japonicum causes an infection involving humans, livestock, and snails and is a significant cause of morbidity in China.
Methods: We evaluated a comprehensive control strategy in two intervention villages and two control villages along Poyang Lake in the southeastern province of Jiangxi, where annual synchronous chemotherapy is routinely used. New interventions, implemented from 2005 through 2007, included removing cattle from snail-infested grasslands, providing farmers with mechanized farm equipment, improving sanitation by supplying tap water and building lavatories and latrines, providing boats with fecal-matter containers, and implementing an intensive health-education program.

Objective: To analyze and compare the spatio-temporal structure and risk factors of county-level seroprevalence of Schistosoma japonicum infection in lake and mountainous regions.
Methods: Bayesian spatio-temporal models were used to analyze the county-level data from serological tests, which was part of the annual reports on S. japonicum infection in China from 2002 to 2005; also used were normalized difference vegetation index (NDVI), land surface temperature (LST), land use type from Moderate Resolution Imaging Spectroradiometer (MODIS), and the index of economic level.
Background: Spatial modeling is increasingly utilized to elucidate relationships between demographic, environmental, and socioeconomic factors, and infectious disease prevalence data. However, there is a paucity of studies focusing on spatio-temporal modeling that take into account the uncertainty of diagnostic techniques.
Methodology/principal Findings: We obtained Schistosoma japonicum prevalence data, based on a standardized indirect hemagglutination assay (IHA), from annual reports from 114 schistosome-endemic villages in Dangtu County, southeastern part of the People's Republic of China, for the period 1995 to 2004.
The aim of this study is to better understand ecological variability related to the distribution of Oncomelania hupensis, the snail intermediate host of Schistosoma japonicum, and predict the spatial distribution of O. hupensis at the local scale in order to develop a more effective control strategy for schistosomiasis in the hilly and mountainous regions of China. A two-pronged approach was applied in this study consisting of a landscape pattern analysis complemented with Bayesian spatial modelling.

Appraisal of the present and future impact of climate change and climate variability on the transmission of infectious diseases is a complex but pressing public health issue. We developed a biology-driven model to assess the potential impact of rising temperature on the transmission of schistosomiasis in China. We found a temperature threshold of 15.

Objective: To estimate the age-specific disability weight of chronic schistosomiasis japonica in China.
Methods: Between October 2004 and January 2005, residents from two schistosome-endemic counties were screened for Schistosoma japonicum infection using an enzyme-linked immunosorbent assay. Disability and morbidity were assessed in seropositive individuals using the European quality of life questionnaire with an additional cognitive dimension (known as the "EQ-5D plus") and ultrasonography.

Objective: To compare the compatibility of three species of freshwater snails, Pomacea canaliculata, Cipangopaludina chinensis, Bellamy a aeruginosa, with Angiostrongylus cantonensis.
Methods: The snails were infected by the first-stage larvae of A. cantonensis under the same conditions.
A Bayesian approach to overcome the imperfections of an immunological test (an antibody-based ELISA) and a parasitological test (Kato-Katz) in the detection of Schistosoma japonicum infection, was used to estimate community prevalences of S. japonicum infection in China. At the same time, the similarity between the prevalence estimates based on data from ELISA alone and those using data from both ELISA and Kato-Katz tests was explored.
