Microsatellite markers from tea green leafhopper Empoasca (Matsumurasca) onukii: a powerful tool for studying genetic structure in tea plantations

Background Tea green leafhopper is one of the most dominant pests in Chinese tea plantations. Recent evidence, including morphological and molecular data, revealed that tea green leafhopper in China is the same species as in Japan, Empoasca (Matsumurasca) onukii Matsuda. Previous morphological study that revealed variation in the structure of the male genitalia within and among...

Acausality in nonlocal gravity theory

We investigate the nonlocal gravity theory by deriving nonlocal equations of motion using the traditional variation principle in a homogeneous background. We focus on a class of models with a linear nonlocal modification term in the action. It is found that the resulting equations of motion contain the advanced Green’s function, implying that there is an acausality problem. As a...

Clarification of the Identity of the Tea Green Leafhopper Based on Morphological Comparison between Chinese and Japanese Specimens

Tea green leafhopper is one of the most dominant pests in major tea production regions of East Asia. This species has been variously identified as Empoasca vitis (Goëthe), Jacobiasca formosana (Paoli) and Empoasca onukii Matsuda in Mainland China, Taiwan and Japan, respectively. Recent study of DNA sequence data suggested that treatment of this pest as different species in these...

A cross-sectional study of irritable bowel syndrome in nurses in China: prevalence and associated psychological and lifestyle factors

evaluation and treatment together with rectification of some unhealthy aspects of current and past lifestyles. Compliance with ethics guidelines Liang LIU, Qi-fan XIAO, Yan-li ZHANG, and Shu-kun YAO declare

Visceral and somatic hypersensitivity, autonomic cardiovascular dysfunction and low-grade inflammation in a subset of irritable bowel syndrome patients

ethics guidelines Liang LIU, Bei-ni LIU, Shuo CHEN, Miao WANG, Yang LIU, Yan-li ZHANG, and Shu-kun YAO declare that they have no conflict of interest. All procedures followed were in accordance with the

An La-related protein controls cell cycle arrest by nuclear retrograde transport of tRNAs during diapause formation in Artemia

Background In eukaryotes, tRNA trafficking between the nucleus and cytoplasm is a complex process connected with cell cycle regulation. Such trafficking is therefore of fundamental importance in cell biology, and disruption of this process has grave consequences for cell viability and survival. To cope with harsh habitats, Artemia has evolved a special reproductive mode to...

Splicing factor 3b subunit 1 (Sf3b1) haploinsufficient mice display features of low risk Myelodysplastic syndromes with ring sideroblasts

Background The presence of somatic mutations in splicing factor 3b subunit 1 (SF3B1) in patients with Myelodysplastic syndromes with ring sideroblasts (MDS-RS) highlights the importance of the RNA-splicing machinery in MDS. We previously reported the presence of bone marrow (BM) RS in Sf3b1 heterozygous (Sf3b1 +/−) mice which are rarely found in mouse models of MDS. Sf3b1...

Satellite-Based Analysis of Evapotranspiration and Water Balance in the Grassland Ecosystems of Dryland East Asia

The regression tree method is used to upscale evapotranspiration (ET) measurements at eddy-covariance (EC) towers to the grassland ecosystems over the Dryland East Asia (DEA). The regression tree model was driven by satellite and meteorology datasets, and explained 82% and 76% of the variations of ET observations in the calibration and validation datasets, respectively. The...

Genome-Wide Profiling of DNA Methylation Reveals a Class of Normally Methylated CpG Island Promoters

The role of CpG island methylation in normal development and cell differentiation is of keen interest, but remains poorly understood. We performed comprehensive DNA methylation profiling of promoter regions in normal peripheral blood by methylated CpG island amplification in combination with microarrays. This technique allowed us to simultaneously determine the methylation status...

A Nitroimidazole Derivative, PR-350, Enhances the Killing of Pancreatic Cancer Cells Exposed to High-dose Irradiation under Hypoxia

The radiosensitizing effects of PR-350, a nitroimidazole derivative, were examined concerning the cell killing of human pancreatic cancer cell lines exposed to high doses of gamma-ray irradiation in vitro. The percentages of dead cells were analyzed with a multiwell plate reader to measure the fluorescence intensity of propidium iodide before and after a digitonin treatment. The...
