Hyaluronan (HA), an abundant polysaccharide found in human bodies, plays a role in the mesenchymal stem cells (MSCs) maintenance. We had previously found that HA prolonged the lifespan, and prevented the cellular aging of murine adipose-derived stromal cells. Recently, we had also summarized the potential pathways associated with HA regulation in human MSCs. In this study, we used the human pla...

plant growth regulators (pgrs) are widely used for lodging control in winter wheat (triticum aestivum l.) grown at high n rates. although the introduction of semi-dwarf wheat cultivars had largely solved the problem of lodging, evidence was already accumu-lating that the timely application of a growth retardant such as chlormequat (ccc) or ethephon could increase the grain yield of wheat, by th...

The essential oil of Rosa damascena Mill. is one of the most valuable and important base material in the flavor and fragrance industry. The aim of this study was to determine the effects of different rates of cow manure on the essential oil of the rose petals. For this a field experiment was conducted on a clay loam soil at the research farm of Alborz research station, Karaj, Iran. Experimental...

Für den Freistaat Thüringen (16,172 km2) wurden räumlich hochaufgelöste Simulationen mit dem dynamische Agrarökosystemmodell MONICA unter Verwendung von Wetterdaten mit hoher, mittlerer und niedriger Informationsdichte mit durchschnittlich auf Kreisebene gemessenen Winterweizenerträgen aus den Jahren 1992 – 2010 (6.7 t ha) verglichen. Unter Verwendung von Daten einer einzelnen Wetterstation wur...

The graft-versus-leukemia effect of allogeneic stem-cell transplantation is believed to be mediated by T-cell recognition of minor histocompatibility antigens on recipient cells. For minor histocompatibility antigens HA-1 and HA-2, normal cell expression is restricted to hemopoietic cells, and boosting the immune response to these antigens may potentiate graft-versus-leukemia effect without acc...

An explicit water molecular dynamics (MD) simulation is presented of a solution modeling aliphatic 6,6-ionene oligocations mixed with low-molecular-weight electrolytes. In all cases, the co-ions were sodium cations and the counterions were fluoride, chloride, bromide, or iodide anions. The simple point charge/extended (SPC/E) model was used to describe water. The results of the simulation at T ...

We describe a novel approach to process bioceramic microparticles and poly(diol citrates) into bioceramic-elastomer composites for potential use in orthopedic surgery. The composite consists of the biodegradable elastomer poly(1,8-octanediol-citrate) (POC) and the bioceramic hydroxyapatite (HA). The objective of this work was to characterize POC-HA composites and assess the feasibility of fabri...

PURPOSE To differentiate radiation necrosis from tumor recurrence using single-photon emission CT (SPECT). METHODS Forty-two thallium-201 SPECT scans were obtained in 33 adult patients. All patients had previously been treated with either conventional external-beam radiation therapy (XRT) (26 patients) or gamma knife radiosurgery (16 patients) and had subsequent contrast-enhanced MR examinati...
