The quantitative investigation of how networks of microtubules contract can boost our understanding of actin biology.

Thromb Haemost 2008; 99: 655–656 Acute pulmonary embolism (PE) and deep venous thrombosis (DVT) are pathophysiologically linked manifestations of the same disease, but their natural course, prognosis, and therapeutic management are quite different in clinical practice. Clearly, the risk of death related to the initial acute episode is higher in patients who present with PE than in those with DV...

From what we can observe, there is no symmetry between matter and antimatter in the Universe. All structures, from unimaginably large clusters of galaxies to microscopic human cells, are made of matter: protons, neutrons, and electrons. Though it is possible to produce antimatter—antiprotons, antineutrons, and positrons—in high-energy particle collisions, and even make medical use of positrons,...

The obvious fact of US global hegemony has taken quite some time to enter public awareness. It is frequently described now, sometimes quite critically, sometimes celebrated as a great blessing to the world – e.g. in Thomas L. Freedman’s The Lexus and the Olive Tree. Understanding Globalisation (1999). Even the notion of an American Empire has come into use, the term often being used in a compla...

Body composition and fatty acid profile of the body tissue of Caspian kutum (Rutilus frisii kutum) fish larvae were determined from fertilized egg to 50 days post hatching (dph). Feeding with rotifer started from day 3 to day 7 thereafter they were fed with dry food until the end of the experiment. The changes observed in lipid content and the decrease in lipid levels during larval ontogeny ref...

background visceral leishmaniasis(vl) is a spreading potentially fatal zoonosis in iran mimicking many other diseases in infancy which differs from vl in some other regions in terms of it’s clinical characteristics and response to therapy; earlier and better management is quite effective for life saving. patients and methods all cases with final diagnosis of vl,2months to 12 years who were disc...
