OBJECTIVE To identify an appropriate cell source for the generation of meniscus substitutes, among those which would be available by arthroscopy of injured knee joints. METHODS Human inner meniscus cells, fat pad cells (FPC), synovial membrane cells (SMC) and articular chondrocytes (AC) were expanded with or without specific growth factors (Transforming growth factor-beta1, Fibroblast growth ...

Pelleting costs money, and better pellets cost a little more. Payback comes in the form of convenience in handling the feed and more efficient use of the feed by the animal. Improved efficiency is due in part to heat processing which reduces pathogens and makes starches more digestible. A significant portion of the improvement is related to the physical form of the pellet. Durable pellets reduc...

The infusion of autologous blood into the brain of rats is a widely used model of intracerebral hemorrhage (ICH). Careful assessment of functional recovery is an essential part of preclinical testing (e.g., putative cytoprotectants). However, few tests detect long-term deficits in this model. In this study, we used the staircase and single pellet tests to characterize skilled reaching ability a...

PURPOSE To study the spatial variances in ligand expression and angiogenic effect in response to the inflammatory response induced by basic fibroblast growth factor (b-FGF). METHODS b-FGF micropellets (80 ng) were implanted in the temporal side of the cornea of Balb/c mice. On days 1, 3, and 7, blood (heme-) and lymphangiogenesis were observed by immunofluorescence staining of corneal flat mo...

Pellet combustion in residential heating stoves has increased globally during the last decade. In this study, environmental simulation chamber experiments were performed to characterize fresh and aged organic aerosol emitted by a pellet stove.

Recent field studies indicate that dinoflagellates are key degraders of copepod fecal pellets. This study is the first to publish direct evidence of pellet grazing by dinoflagellates. Feeding and growth on copepod fecal pellets were studied for both heterotrophic (4 species) and mixotrophic dinoflagellates (3 species) using a combination of classic incubation experiments and video recordings of...

The microinjection of cytoplasm taken from one strain of large free-living amoeba into another strain is followed by an incompatibility phenomenon, the inhibition of division amongst the recipient cells. The post-microsomal supernatant fraction from Amoeba discoides (T1D13) injected into A. proteus (T1P) inhibited division in 90% of the injected cells. Further centrifugation of this fraction yi...

Background: The dose rate distribution delivered by a low dose rate 137Cs pellet source, a spherical source used within the source trains of the Selectron gynecological brachytherapy system, was investigated using the MCNP4C Monte Carlo code. Materials and Methods: The calculations were performed in both water and Plexiglas and the absolute dose rate distribution for a single pellet s...

Objective: In this study investigated effects of different amounts of pelleted manure with urea and micro elements on yield and seed quality of medicinal plants, pumpkin (Cucurbita pepo var. styriaca). Methods: The animal manure and urea as pellet with four levels (150 Kg urea, 50 Kg urea + 3.5 ton animal manure, 100 (Kg) urea+ 1.5 ton animal manure and 150 (Kg) urea+1.5 ton animal man...
