Objective- To evaluate the healing potential of oleaster leave water soluble extract on skin wounds. Design- Experimental study. Animals- 30 male Spragne-Dawly rats, randomly assigned in two equal groups. Procedures- Under general anesthesia, and following surgical preparation, two uniform skin defects were made by 7mm skin punch. The water soluble extract was then applied on half of the wo...

We show that if $w$ is a multilinear commutator word and $G$ finite group in which every metanilpotent subgroup generated by $w$-values of rank at most $r$, then the verbal $w(G)$ bounded terms $r$ only. In case where soluble we obtain better result -- nilpotent $r+1$.

We consider the class of groups whose word problem is poly-contextfree; that is, an intersection of finitely many context-free languages. We show that any group which is virtually a finitely generated subgroup of a direct product of free groups has poly-context-free word problem, and conjecture that the converse also holds. We prove our conjecture for several classes of soluble groups, includin...

BACKGROUND AND AIMS Enteral fiber-free diets alter intestinal transit and produce diarrhea or constipation. This prospective double blind, controlled study evaluates the use of guar gum, a soluble fiber and a candidate prebiotic in enteral feeds, to prevent diarrhea and potential health benefits in intensive care unit patients. METHODS Twenty patients on enteral nutrition with persistent diar...

A series of new polyamides containing maleimide pendant group were prepared by low temperature polycondensation of 5-(4-(2,5-dioxo-2H-pyrrol-1(5H)-yl)benzamido)isophthaloyl chloride as a new monomer with various aromatic diamines in NMP. Monomer and polymers structures were identified through FT-IR, 1H-NMR and elemental analysis. Obtained polymers were soluble in polar solvents and non solu...

OBJECTIVES One of the most frequent complications in cardiac surgery is postoperative bleeding from the sternum. To diminish the risk of bleeding, bone wax is frequently used for haemostasis. However, we have previously shown that bone wax impairs bone healing and induces inflammation in the sternum. A new, water-soluble polymer wax enriched with gentamicin has haemostatic properties similar to...

Physiological challenges during one part of the annual cycle can carry over and affect performance at a subsequent phase, and antioxidants could be one mediator of trade-offs between phases. We performed a controlled experiment with zebra finches to examine how songbirds use nutrition to manage trade-offs in antioxidant allocation between endurance flight and subsequent reproduction. Our treatm...
