A water-soluble cationic porphyrin, 5,10,15,20-Tetra(N-methylpyridinium-4-yl)-21H,23H-porphyrin has been shown to intercalate selectively into the A3-G4 gap of C-quadruplexed DNA d(TTAGGG)4.

in the present study ethanol and water extracts of 15 seaweeds, dictyota dichotoma var. velutricata, dictyota indica, iyengaria stellata, padina pavonia, sargassum swartzii, sargassum variegatum, stoechospermum marginatum, stokeyia indica, jolyna laminarioides, caulerpa taxifolia, halimeda tuna, ulva fasciata, ulva lactuca, solieria robusta, and melanothamnus afaqhusainii, were evaluated for th...

Molecular weight distribution of prion proteins in meat, blood, processed blood products, gelatin, milk, cheese has been studied in a paper. The obtained electrophoregrams of blood plasma samples indicate the presence of two fractions of blood protein in the range of 30 to 40 kDa. The relative abundance of these proteins in the blood plasma contains 22.06 % of the total, which are 2.15 g/100 g ...

stereoselectivity of mefloquine enantiomers were studied in rats after oral administration of a single 50mg/kg dose of the racemate. pharmacokinetic parameters of (+)-(rs)-mfq in blood and plasma showed no significant difference. the concentration, auc , clif and vdlf of (+)-(rs)-enantiomerin blood were significantly higher than those for the (-)-(sr)-enantiomer. tlie results obtained from this...

The aim of the research was to determine the concentration of total protein and its fractions as well as the concentration of selected mineral components in the blood serum of male broiler chickens Cobb 500 fed diets with different cellulose content. Blood samples were collected for examination from the birds' pterygoid canal veins on their 42 day of age. There was no influence of cellulose pre...

Cord blood is a potential source of hematopoietic stem cells for transplantation and is being used on a growing number of patients. However, there are concerns that cord blood might be contaminated with maternal cells that could lead to graft-versus-host disease. To ascertain the extent to which maternal cell contamination of cord blood occurs, we examined 49 cord blood samples from male babies...

Background: The risk of hepatitis C virus (HCV) transmission during assisted reproductive techniques (ARTs) is still disputed and no report concerning its prospective evaluation is available. The aim of this 4-year follow-up multicentre study that enrolled 86 HCV-serodiscordant couples was to determine whether a sperm-processing method was able to reduce levels of HCV in semen and the risk of H...

Multidrug resistance (MDR) continues to be a major obstacle for successful anticancer therapy. In this work, fractions from 17 clinically used antitumour traditional Chinese medicinal herbs were tested for their potential to restore the sensitivity of MCF-7/ADR and A549/Taxol cells to a known antineoplastic agent. The effects of these fractions were evaluated by MTT method and an assay of the c...
