Bacteria play an important role in the decomposition and cycling of a variety of compounds in freshwater aquatic environments, particularly nutrient-rich eutrophic lakes. A unique Chinese eutrophic lake--Dianchi--was selected for study because it has two separate and distinct basins, Caohai with higher organic carbon levels and Waihai with lower organic(More)
Dianchi Lake is a typical Chinese eutrophic lake. The bacterial community in the polluted water of the Dianchi lakeshore was investigated by cultivation-independent approaches. The amplicon length heterogeneity polymerase-chain reaction (LH-PCR) was used to detect the major differences in bacterial structure among the nine different sampling sites. Cluster(More)
We explored the regulation of erythropoietin and erythropoietin receptor on traumatic brain injury (TBI), as well as the antiapoptotic effects of recombinant human erythropoietin (rhEPO) treatment. Female Wistar rats were randomly divided into three groups: rhEPO-treated TBI, vehicle-treated TBI, and sham-operated. TBI was induced by the Feeney free falling(More)
BACKGROUND Through adaptation, animals can function visually under an extremely broad range of light intensities. Light adaptation starts in the retina, through shifts in photoreceptor sensitivity and kinetics plus modulation of visual processing in retinal circuits. Although considerable research has been conducted on retinal adaptation in nocturnal(More)
Mesenchymal stem cells (MSCs) are a potential source of adult stem cells for cell-based therapeutics due to their substantial multilineage differentiation capacity and secretory functions. No information is presently available regarding the maintenance of immunosuppressive properties of this cell type with repeated passages. It was therefore the aim of the(More)
Cystic fibrosis (CF) is the most common life-limiting recessive genetic disease among Caucasians caused by mutations of the cystic fibrosis transmembrane conductance regulator (CFTR) with over 95% male patients infertile. However, whether CFTR mutations could affect spermatogenesis and result in azoospermia remains an open question. Here we report(More)
OBJECTIVE To evaluate the impact of mesenchymal stem cells (MSCs) against hepatic I/R injury and explore the role of N-acetyltransferase 8 (NAT8) in the process. METHODS We investigated the potential of injected MSCs systemically via the tail vein in healing injuried liver of the SD rat model of 70% hepatic I/R injury by measuring the biochemical and(More)
Putrescine (Put), spermidine (Spd), and spermine (Spm) are the major polyamines (PAs) in plant, which are not only involved in the regulation of plant developmental and physiological processes, but also play key roles in modulating the defense response of plants to diverse environmental stresses. In this study, Cucumis sativus L. seedlings were cultivated(More)
The immunomodulatory and anti-oxidative activities of differentiated mesenchymal stem cells contribute to their therapeutic efficacy in cell-replacement therapy. Mesenchymal stem cells were isolated from human umbilical cord and induced to differentiate with basic fibroblast growth factor, nerve growth factor, epidermal growth factor, brain-derived(More)
New information regarding the relationship between the agonist receptor and the regulatory and catalytic components of adenylate cyclase has been obtained by applying forskolin in combination with several different activators of adenylate cyclase. Adipocyte adenylate cyclase cannot be fully activated by forskolin; maximal stimulation by forskolin can be(More)
