suave, B. pilosa, neomycin sulfate Apoptosis inhibitor or distilled water. The rate of wound contraction, epithelialization, and complete healing were assessed over the experimental
period. Wounds treated with extracts of O. suave, B. pilosa and neomycin sulfate had faster rates of wound contraction (p<0.05) on days 3, 6 and 9 than negative control. Histological examination of wound on day 7 also revealed better collagenation, angiogenesis and organization of the wound tissue. Epithelialisation and total healing time for B. pilosa and O. suave were comparable to neomycin sulfate (p>0.05). In conclusion, extracts of O. suave and B. pilosa show potential for use as alternative to neomycin for treatment of wounds.”
“Lignophenol (LP)-graft-poly(2-ethyl-2-oxazoline) (POZO) was prepared to reuse lignin, an industrial waste material, and to
produce BVD-523 inhibitor novel LP-based polymer blends with poly(vinyl chloride) (PVC), poly(bisphenol A carbonate) (PC), polyvinylpyrrolidone (PVP), and polystyrene (PSt) as commodity polymers. The resulting graft polymer was soluble in various types of organic solvents such as chloroform, THF, acetone, and methanol, unlike LP. The miscibility of LP-graft-POZO with commodity polymers was measured by differential scanning calorimetry (DSC) to determine the glass transition temperatures (Tg). In the cases of the blends of LP-graft-POZO with PVC, PC, and PVP, the Tg values decreased during the second scan. Moreover, in the cases of the blends with PVC and PVP, the Tg values were not detected during the third scan. Therefore, it was inferred that LP-graft-POZO was miscible with PVC, PC, and PVP while forming single phases; in particular, the blends of LP-graft-POZO with PVC and PVP exhibited a secondary miscibility because the Tg values were not detected. Furthermore, the blend of LP-graft-POZO with PC exhibited better thermostability than LP and LP-graft-POZO. These results indicated that LP blended with POZO could be used as a polymer KU-55933 additive and as an adhesive to combine different polymers, organicinorganic polymers, etc. (c) 2011 Wiley

“Background: The use of artemisinin-based combination therapy (ACT) is currently recommended for treating uncomplicated malaria. The objective was to assess the efficacy and safety of repeated administrations of two fixed-dose presentations of ACT – artesunate plus amodiaquine (ASAQ) and artemether-lumefantrine (AL) – in subsequent episodes of Plasmodium falciparum malaria.
Methods: A randomized comparative study was conducted in a rural community of central Senegal from August 2007 to January 2009. Children and adults with uncomplicated P. falciparum malaria were randomized to receive open-label ASAQ once daily or AL twice daily for three days. Drug doses were given according to body weight. Treatments for first episodes were supervised.
