BACKGROUND AND AIM OF THE STUDY A new-generation heart valve was developed to improve long-term durability. The study aim was to evaluate the need for in-vitro autologous endothelial cell seeding of a decellularized valve scaffold. METHODS A seeded (group I, n = 6) or non-seeded (group II, n=6) decellularized valve was implanted into the right ventricular outflow tract of 12 juvenile sheep. I...

most studies regarding the marrow-derived equine mesenchymal stem cells (mscs) have mainly focusedon the cell transplantation without considering the capacity of differentiation and in vitro requirements of thecells. these concerns were investigated in the present study. equine mscs were isolated from the sternalmarrow aspirates and expanded through two successive subcultures. passage-2 equine ...

Filamentous species of Ulva are ideal for cultivation because they are robust with high growth rates and maintained across a broad range of environments. Temperate species of filamentous Ulva are commercially cultivated on nets which can be artificially 'seeded' under controlled conditions allowing for a high level of control over seeding density and consequently biomass production. This study ...

Cellular fibronectin is deposited on tissue culture polystyrene during the adhesion and spreading of cultured human endothelial cells (HEC). Following the seeding of HEC upon this polymer, larger amounts of fibronectin are deposited as both cell density and incubation time increase. Our results indicate that the ability to deposit cellular fibronectin onto a polymeric surface is a condition for...

We present a simple and robust method to evaluate the transfection efficiency of commercially available transfection reagents intended to be established for use in nonmammalian cell lines. To illustrate the method, we compare the ability of four different reagents to transfect the embryonic zebrafish cell line Z3. Z3 cells were seeded in a 96-well plate and simultaneously transfected in several...

We report the first observation of laser seeding of the storage-ring microbunching instability. Above a threshold bunch current, the interaction of the beam and its radiation results in a coherent instability, observed as a series of stochastic bursts of coherent synchrotron radiation (CSR) at terahertz frequencies initiated by fluctuations in the beam density. We have observed that this effect...

The cohesion-tension theory of water transport states that hydrogen bonds hold water molecules together and that they are pulled through the xylem under tension. This tension could cause transport failure in at least two ways: collapse of the conduit walls (implosion), or rupture of the water column through air-seeding. The objective of this research was to elucidate the functional significance...

Western juniper (Juniperus occidentalis ssp. occidentalis Hook) encroachment into mountain big sagebrush (Artemisia tridentata spp. vaseyana (Rydb.) Beetle) steppe has reduced livestock forage production, increased erosion risk, and degraded sagebrush-associated wildlife habitat. Western juniper has been successfully controlled with partial cutting followed by prescribed burning the next fall, ...

Leptomeningeal seeding is a strong negative prognostic factor for medulloblastoma (MB). The mechanism of leptomeningeal seeding is unclear but may involve epigenetic regulation. In this study, we evaluated the feasibility of a histone deacetylase (HDAC) inhibitor, panobinostat, in the suppression of MB leptomeningeal seeding. Panobinostat decreased the cell viability and proliferation, inducing...
