Conditioned medium from activated spleen cells supports the survival of rat retinal cells in vitro BJMBR
Sholl-Franco,A.; Araujo,E.G..
Cytokines are a heterogeneous group of molecules that have been associated with several functions in the nervous system, such as survival and differentiation of neuronal and glial cells. In the present study, we demonstrated that conditioned medium from spleen cells activated with concanavalin A increased neuritogenesis and survival of retinal cells, as measured by biochemical and morphological criteria. Our data showed that conditioned medium induced a five-fold increase in the amount of protein after 120 h in vitro. This effect was not inhibited by the blockade of voltage-dependent L-type calcium channels with 5.0 µM nifedipine. However, the use of an intracellular calcium chelator (15.0 µM BAPTA-AM) inhibited this effect. Our results support the idea...

Effects of chestnut ( Castanea sativa ) meal supplementation on growth performance, carcass characteristics, and meat quality of pigs R. Bras. Zootec.
Joo,Young Ho; Choi,In Hag; Kim,Dong Hyeon; Lee,Hyuk Jun; Amanullah,Sardar M.; Yang,Han Sul; Kim,Sam Churl.
ABSTRACT This study examined the effect of chestnut ( Castanea sativa ) meal (CNM) on growth performance, carcass characteristics, and meat quality of pigs. Thirty-two crossbred pigs were randomly allocated equally into four groups and fed one of four diets containing 0, 30, 50, or 100 g kg−1 DM CNM for 49 days. The animals were housed individually into the cage, fed the diet ad libitum , and allowed to access water freely. Feed efficiency decreased quadratically, while carcass yield decreased linearly with increasing CNM supplementation. The highest pH and the lowest drip loss were found in 30 g kg−1 of CNM supplementation, respectively, while no effects on fatty acid profiles were observed in all treatments. The addition of CNM at 30 g kg−1 into the...

Influence of fermented fish meal supplementation on growth performance, blood metabolites, and fecal microflora of weaning pigs R. Bras. Zootec.
Lee,Hyuk Jun; Choi,In Hag; Kim,Dong Hyeon; Joo,Young Ho; Kim,Sam Churl.
ABSTRACT This study was conducted to estimate the effect of dietary supplementation with fermented fish meal on growth performance, blood metabolites, and fecal microflora in weaning pigs. A total of 180 weaned pigs ((Landrace ×Yorkshire) × Duroc; with average body weight of 6.0 kg) were randomly distributed among three dietary treatments (0, 0.2, and 0.5% fermented fish meal) in three replicate pens (20 heads per pen) in a completely randomized trial over three weeks. Addition of fermented fish meal to weanling pig diets had a linear effect on average feed intake and a quadratic trend on final body weight, average daily gain, and gain:feed ratio throughout the whole period (but not initial body weight). Hematocrit, monocyte, immunoglobulin G, and blood...

Microcarriers Based on Glycosaminoglycan-Like Marine Exopolysaccharide for TGF-β1 Long-Term Protection ArchiMer
Zykwinska, Agata; Marquis, Melanie; Godin, Mathilde; Marchand, Laetitia; Sinquin, Corinne; Garnier, Catherine; Jonchere, Camille; Chedeville, Claire; Le Visage, Catherine; Guicheux, Jerome; Colliec-jouault, Sylvia; Cuenot, Stephane.
Articular cartilage is an avascular, non-innervated connective tissue with limited ability to regenerate. Articular degenerative processes arising from trauma, inflammation or due to aging are thus irreversible and may induce the loss of the joint function. To repair cartilaginous defects, tissue engineering approaches are under intense development. Association of cells and signalling proteins, such as growth factors, with biocompatible hydrogel matrix may lead to the regeneration of the healthy tissue. One current strategy to enhance both growth factor bioactivity and bioavailability is based on the delivery of these signalling proteins in microcarriers. In this context, the aim of the present study was to develop microcarriers by encapsulating...

Regulation of MMP2 and MMP9 metalloproteinases by FSH and growth factors in bovine granulosa cells Genet. Mol. Biol.
Portela,Valerio M.; Veiga,Angela; Price,Christopher A..
Matrix metalloproteinases (MMP) are key enzymes involved in tissue remodeling. Within the ovary, they are believed to play a major role in ovulation, and have been linked to follicle atresia. To gain insight into the regulation of MMPs, we measured the effect of hormones and growth factors on MMP2 and MMP9 mRNA levels in non-luteinizing granulosa cells in serum-free culture. FSH and IGF1 both stimulated estradiol secretion and inhibited MMP2 and MMP9 mRNA abundance. In contrast, EGF and FGF2 both inhibited estradiol secretion but had no effect on MMP expression. At physiological doses, none of these hormones altered the proportion of dead cells. Although we cannot link MMP expression with apoptosis, the specific down regulation by the gonadotropic hormones...
