There are concerns about the health effects of formaldehyde exposure, including carcinogenicity, in light of elevated indoor air levels in new homes and occupational exposures experienced by workers in health care, embalming, manufacturing, and other industries. Epidemiologic studies suggest that formaldehyde exposure is associated with an increased risk of(More)
To assess effects of postconditioning with the vagal stimulation (VS) on the local and systematic inflammatory responses to acute myocardial ischemia reperfusion injury (IRI). Sixty male Sprague–Dawley rats were randomly allocated into three groups: sham group, ischemia reperfusion group (IR group), and postconditioning with the VS group (POVS group). Serum(More)
Histone modifications play a vital role in the con-formation and function of their associated chromatin templates [1]. Histone H3K27 methylation mediated by the PRC2 complex is critical for transcriptional regulation , Polycomb silencing, Drosophila segmentation, mammalian X inactivation and cancer [1]. Interestingly, H3K27me1 (H3 mono-methylated at residue(More)
Two copies of each core histone exist in every nucleosome; however, it is not known whether both histones within a nucleosome are required to be symmetrically methylated at the same lysine residues. We report that for most lysine methylation states, wild-type histones paired with mutant, unmethylatable histones in mononucleosomes have comparable methylation(More)
Occupational cohort and case-control studies suggest that trichloroethylene (TCE) exposure may be associated with non-Hodgkin lymphoma (NHL) but findings are not consistent. There is a need for mechanistic studies to evaluate the biologic plausibility of this association. We carried out a cross-sectional molecular epidemiology study of 80 healthy workers(More)
Future application of adult stem cells in clinical therapies largely depends on the successful isolation of homogeneous stem cells with high plasticity. Multipotent adult progenitor cells (MAPCs) are thought to be a more primitive stem cell population capable of extensive in vitro proliferation with no senescence or loss of differentiation capability. The(More)
Considering that the dosage of manipulating Moxa plays an important role in obtaining good effects for heat-sensitive moxibustion, it would be valuable to know whether the use of fixed dosage is as effective as the use of an individual one. The paper carried out a rigorous multi-centre randomized controlled trial, and its result demonstrated that the(More)
Epidemiological studies suggest that trichloroethylene (TCE) exposure may be associated with renal cancer. The biological mechanisms involved are not exactly known although nephrotoxicity is believed to play a role. Studies on TCE nephrotoxicity among humans, however, have been largely inconsistent. We studied kidney toxicity in Chinese factory workers(More)
Deconvolution wide-field fluorescence microscopy and single-particle tracking were used to study the three-dimensional mobility of single secretory granules in live PC12 cells. Acridine orange-labeled granules were found to travel primarily in random and caged diffusion, whereas only a small fraction of granules traveled in directed fashion. High K(+)(More)
