De novo expression in the kidney of periostin, a protein involved in odontogenesis and osteogenesis, has been suggested as a biomarker of renal disease. In this study, we investigated the mechanism(s) of induction and the role of periostin in renal disease. Using a combination of bioinformatics, reporter assay, and chromatin immunoprecipitation analyses, we found that NFκB and other proinflammatory transcription factors induce periostin expression in vitro and that binding of these factors on the periostin promoter is enriched in glomeruli during experimental GN...

BACKGROUND: Gram-negative bacteria are associated with significant morbidity and mortality in preterm and term newborns. Meropenem has widespread efficacy and often allows for monotherapy in this group. Prolonged infusion instead of infusion over 30 minutes has been suggested to result in higher microbiologic efficacy. OBJECTIVE: To compare the clinical and microbiologic efficacy and safety of prolonged infusions versus conventional dosing of meropenem in neonates with Gram negative late onset sepsis (GN-LOS)...

We tested the effects of microiontophoretic application of serotonin (5-HT) on the firing rate of neurons located in the gracile nucleus (GN) of rats. Application of 5-HT1A and 5-HT2 agonists and antagonists respectively mimicked/ modulated and blocked the effects produced by the amine, respectively. Among the tested neurons, 88.2% modified their background firing activity in the presence of 5-HT. Responsive neurons decreased their mean firing activity (MFA) in 56.7% of cases and increased it in the remaining 43...

Gomisin N (GN) is a phytochemical derived from Schisandra chinensis. It has been reported to exert a protective effect against hepatic steatosis by attenuating endoplasmic recticulum (ER) stress. However, the detailed mechanism by which GN inhibits hepatic steatosis remains to be elucidated. In this study, we examined whether GN activates AMP-activated protein kinase (AMPK) and exerts therapeutic effects on liver X receptor (LXR)- or palmitic acid (PA)-induced triglyceride (TG) accumulation in HepG2 cells. Furthermore, in vivo protective effects of GN against hepatic steatosis were assessed in high-fat diet (HFD)-induced obese mice...

Fatigued walking condition (FWC) in ducks is an important welfare and processing issue during the loading/unloading to the processing plant that can be related to heart and bone development. An experiment was conducted to evaluate the effects of incubation conditions on duck embryo bone and heart development and their subsequent effects on ducks showing FWC at market age. Four groups of 2500 Pekin duck eggs were subjected to combinations of two incubation temperature profiles (elevated [E] and normal [N]) and two eggshell conductance profiles (G) (reduced [GR] and normal [GN])...

For several decades, glucocorticoids have been used empirically to treat rapid progressive GN. It is commonly assumed that glucocorticoids act primarily by dampening the immune response, but the mechanisms remain incompletely understood. In this study, we inactivated the glucocorticoid receptor (GR) specifically in kidney epithelial cells using Pax8-Cre/GR(fl/fl) mice. Pax8-Cre/GR(fl/fl) mice did not exhibit an overt spontaneous phenotype. In mice treated with nephrotoxic serum to induce crescentic nephritis (rapidly progressive GN), this genetic inactivation of the GR in kidney epithelial cells exerted renal benefits, including inhibition of albuminuria and cellular crescent formation, similar to the renal benefits observed with high-dose prednisolone in control mice...

BACKGROUND: Longer life expectancy is associated with an increasing prevalence of kidney disease. Aging itself may cause renal damage, but the spectrum of kidney disorders that affect elderly patients is diverse. Few studies, mostly form US, Asia and West Europe found differences in the prevalence of some types of kidney diseases between elderly and younger patients based on renal biopsy findings, with varied proportion between glomerulopathies and arterionephrosclerosis as a dominant injury found...

Ganglioneuroma (GN) is the uncommon, benign representative of the peripheral neuroblastic tumours (PNTs), which arise from primitive sympathetic ganglion cells. PNTs comprise one of the most common groups of neoplastic diseases in infants and children, but its occurrence in the pancreas is rare. We report a 4-year-old girl with GN of the pancreas requiring pancreaticoduodenectomy as a definitive therapy and with a great outcome, and we review the published literature.

Robert Oven
Electrically poled layers have been formed in soda-lime glass using graphite electrodes in air. The refractive index and thickness of the poled glass layers have been measured by the analysis of leaky optical modes. These modes are supported by the poled layer and can be determined by analysis of the optical reflectivity measured with a prism coupler arrangement. A relatively constant refractive index of ∼1.486 in the poled glass region is measured, which is ∼0.03 below the substrate index. The reflectivity data shows that the transition between poled and unpoled glass is very sharp and is consistent with ion transport models...

The severe fever with thrombocytopenia syndrome virus (SFTSV) is an emerging, highly pathogenic bunyavirus against which neither antivirals nor vaccines are available. The SFTSV glycoproteins, Gn and Gc, facilitate viral entry into host cells. Gn and Gc are generated from a precursor protein, Gn/Gc, but it is currently unknown how the precursor is converted into the single proteins and whether this process is required for viral infectivity. Employing a rhabdoviral pseudotyping system, we demonstrate that a predicted signal sequence at the N-terminus of Gc is required for Gn/Gc processing and viral infectivity while potential proprotein convertase cleavage sites in Gc are dispensable...

Nitrogen and water are two important factors influencing GHG (primarily CO2 - carbon dioxide; CH4 - methane, and N2O - nitrous oxide) fluxes in semiarid grasslands. However, the interactive effects of nitrogen and water on GHG fluxes remain elusive. A 3-year (2010-2012) manipulative experiment was conducted to investigate the individual and interactive effects of nitrogen and water additions on GHG fluxes during growing seasons (May to September) in a semiarid grassland in Northern China. Accumulated throughout growing seasons, nitrogen input stimulated CO2 uptake by 3...

BACKGROUND: Rotavirus vaccines have poor efficacy in infants from low- and middle-income countries. Gut microbiota is thought to influence the immune response to oral vaccines. Thus, we developed a gnotobiotic (Gn) pig model of enteric dysbiosis to study the effects of human gut microbiota (HGM) on immune responses to rotavirus vaccination, and the effects of rotavirus challenge on the HGM by colonizing Gn pigs with healthy HGM (HHGM) or unhealthy HGM (UHGM). The UHGM was from a Nicaraguan infant with a high enteropathy score (ES) and no seroconversion following administration of oral rotavirus vaccine, while the converse was characteristic of the HHGM...
