A series of previous studies with quebracho tannin (QT) had shown that the tannin was effective at reducing the worm burden of temperate sheep infected with Haemonchus and Trichostrongylus. The potential of using tanniniferous browse plants available in the tropics as a means to reduce or control nematode infections of small ruminants was, therefore, investigated. Leaves of different browse tre...

Code analysis and simulation of network worm infection are useful methods to evaluate how it spreads and its effects [1]. But a bug in infection algorithm or the way of implementing a random number generator etc. affects the retrieval behavior of network worm infection. It is important to evaluate the retrieval behavior of network worm infection in an experimental environment for complementing ...

Giant and stable worm micelles formed from poly(ethylene glycol) (PEG)-based diblock copolymer amphiphiles have the potential advantage compared to smaller assemblies for delivery of a large quantity of hydrophobic drugs or dyes per carrier. Here we show that worm micelles can be targeted to cells with internalization and delivery of nontoxic dyes as well as cytotoxic drugs. Constituent copolym...

-1. Tobacco hornworms, Manduca sexta, were reared on either tobacco leaves or synthetic diet. 2. Glucose and trehalose levels in the hemolymph were significantly lower in leaf-reared larvae. 3. Levels of trehalose were higher in the earlier part of each stadium. 4. Fourth stadium levels of trehalose were generally greater than fifth stadium levels. 5. Trehalose, but not glucose, levels were low...

In 1963 Sydney Brenner proposed to study the development of multi-cellular organisms using a genetic approach in a simple animal. He settled on a small, transparent nematode, Caenorhabditis elegans, which develops quickly and is anatomically simple with less than a thousand somatic cells. Almost half a century later there are many more researchers studying C. elegans than there are somatic cell...

Benzyl methacrylate (BzMA) is polymerized using a poly(lauryl methacrylate) macromolecular chain transfer agent (PLMA macro-CTA) using reversible addition-fragmentation chain transfer (RAFT) polymerization at 70 °C in n-dodecane. This choice of solvent leads to an efficient dispersion polymerization, with polymerization-induced self-assembly (PISA) occurring via the growing PBzMA block to produ...

SUMMARY hydatic cyst is a serious disease of man. That cause by a worm called taenia echinocococus, the adult worm lives in small bowel of dog and other canine host. The dog is the usual definitive host of this parasite and is important for transmition of this disease. In this study a total of 283 stray dags Teheran country were investigated for the present of intestinal metazoan parasites. T...
