HL-7702


titanium oxide / chitosan composite scaffolds were prepared by a freeze-drying technique. Composite scaffolds were very porous with an average pore size of 120-300 microns, and titanium dioxide (TiO (2)) powders were uniformly dispersed on the surface of the pore walls. The compressive strength of the composite scaffolds was significantly improved compared to that of pure chitosan scaffolds. weight / chitosan composite scaffold with 0.3 TiO (2) showed resistance to the maximum compression 159.7 +/- 21 kPa. Liver immortal cell line HL-7702 was used as seed cells on the scaffold, and after periods of cultivation different investigated adhesion and cell function. HL-7702 in adhering to the walls of the scaffold pores with spheroid shape after 1 day of culture cells, but aggregates of cells in the formed TiO (2) / chitosan composite scaffolds compared to scaffolds of pure chitosan. specific functions of the liver, the secretion of albumin and urea synthesis were detected using a spectrometric method. The results showed that the secretion and urea synthesis rate of albumin HL-7702 cells slightly reduced with the time of culture, and there was no significant difference between the composite scaffolds and chitosan scaffolds pure. In conclusion, the TiO (2) / chitosan composite scaffolds had improved compared to pure chitosan scaffolds mechanical strength and supports the setting and functional expression of hepatocytes, which means that their possible application in tissue engineering of the liver.

Injustice through the ages, because DNA expelled!

A few weeks ago, in a middle school in Palo Alto, Colman Chadam is ready to ascend to the sixth grade, he was the school drop-out requirements, because his father and mother told the teacher said something about his DNA thing.

After genetic testing, Chadam has cystic fibrosis genetic markers - a rare genetic disease, seriously affecting the lungs and digestive system, the patient vulnerable to infection. These markers does not mean that he suffers from the disease, and there has never been any Chadam-related symptoms, the most irritating is that he's already had two schools with cystic fibrosis admitted students, Chadam the people have kept the ring!

Still it sounds crazy? Yes, but no.

Yes, that's because, although DNA is such tips, but Chadam never been diagnosed with cystic fibrosis. The school seems to do his own to do, because patients suffering from cystic fibrosis need to be isolated, in the face of specific bacteria, they are prone to cross-infection.

"In patients with cystic fibrosis, the mucus can clog the lungs strong and conducive to bacterial growth and reproduction. Long-term accumulation makes them more prone to lung infections," said the US Cystic Fibrosis Foundation.

When more than one school in cystic fibrosis patients is best to keep a distance of at least 1.8 meters between them. Airborne bacteria can spread as droplets almost 1.8 meters away.

Chadam parents declared that they would secretly medical information to tell his son after school, there is a teacher this information leaked to the school with other parents of children suffering from cystic fibrosis. They complained that other children would Chadam enrollment serious health threat, Chadam was asked to drop out.

I say "claims" because this happened in 2012, after which, Chadam parents have been trying to prosecute the crime of genetic discrimination schools.

Prednicarbate


A synthetic non-halogenated double-ester derivative of the corticosteroid prednisolone with anti-inflammatory, antipruritic and vasoconstrictive properties. Following skin permeation, prednicarbate enters cells and binds to and activates specific nuclear receptors, resulting in an altered gene expression and inhibition of pro-inflammatory cytokine production by increasing the expression of lipocortins. These block phospholipase A-dependent release of arachidonic acid thereby inhibiting prostaglandin synthesis. This agent also decreases the number of circulating lymphocytes by suppression of the production of vasodilators such as prostacyclin and nitric oxide.
