Anaplasma (formerly Ehrlichia) phagocytophilum, Ehrlichia chaffeensis, and Neorickettsia (formerly Ehrlichia) sennetsu are intracellular vector-borne pathogens that cause human ehrlichiosis, an emerging infectious disease. We present the complete genome sequences of these organisms along with comparisons to other organisms in the Rickettsiales order.(More)
A novel bacterium that infects laboratory rats was isolated from wild Rattus norvegicus rats in Japan. Transmission electron microscopy of the spleen tissue revealed small cocci surrounded by an inner membrane and a thin, rippled outer membrane in a membrane-bound inclusion within the cytoplasm of endothelial cells. Phylogenetic analysis of the 16S rRNA(More)
Long-term field research has revealed that male chimpanzees, Pan troglodytes, affiliate and cooperate in several contexts. Assuming close genetic relationship among males, affiliative and cooperative behaviour have been hypothesized to evolve through the indirect effects of kin selection. We tested the hypothesis that matrilineal genetic relatedness affects(More)
A total of 20 human patients with clinical signs compatible with human monocytic ehrlichiosis (HME), who were admitted to the emergency clinic in Lara State, Venezuela, were studied. Thirty percent (6/20) patients were positive for Ehrlichia canis 16S rRNA on gene-specific polymerase chain reaction (PCR). Compared with the U.S. strains, 16S rRNA gene(More)
UNLABELLED cAMP responsive element-binding protein, hepatocyte specific (CREBH), is a liver-specific transcription factor localized in the endoplasmic reticulum (ER) membrane. Our previous work demonstrated that CREBH is activated by ER stress or inflammatory stimuli to induce an acute-phase hepatic inflammation. Here, we demonstrate that CREBH is a key(More)
BACKGROUND & AIMS Air pollution is a global challenge to public health. Epidemiological studies have linked exposure to ambient particulate matter with aerodynamic diameters<2.5 μm (PM(2.5)) to the development of metabolic diseases. In this study, we investigated the effect of PM(2.5) exposure on liver pathogenesis and the mechanism by which ambient PM(2.5)(More)
PROBLEM We investigated host immunologic responses to endometriosis by comparing immune cell surface antigens in peripheral blood (PB) and peritoneal fluid (PF) from women with endometriosis with those in PB and PF from other patients. METHOD OF STUDY Japanese women with endometriosis (n = 56) were compared with controls with other laparoscopic diagnoses(More)
Reproductive period (RP) is an important trait of soybean [Glycine max (L.) Merr.] It is closely related to yield, quality and tolerances to environmental stresses. To investigate the inheritance and photoperiod response of RP in soybean, the F1, F2, and F2:3 populations derived from nine crosses were developed. The inheritance of RP was analyzed through(More)
Recent studies have suggested a link between inhaled particulate matter (PM) exposure and increased mortality and morbidity associated with pulmonary and cardiovascular diseases. However, a precise understanding of the biological mechanism underlying PM-associated toxicity and pathogenesis remains elusive. Here, we investigated the impact of PM exposure in(More)
The two-component system (TCS) composed of a pair of a sensor histidine kinase and a response regulator, allows bacteria to sense signals and respond to changes in their environment through specific gene activation or repression. The present study examined TCS in the obligatory intracellular bacteria Ehrlichia chaffeensis and Anaplasma phagocytophilum, that(More)
