In this issue, Sabin et al. (2009) and Gruber et al. (2009) reveal the protein Ars2 as a versatile regulator of RNA silencing. They show that Ars2 stimulates microRNA processing, contributes to antiviral resistance in flies, and is important for cell proliferation in mammals.
lop? This question is as simple as it is fundamental to the understanding of the lymphatic system (LS) under physiological and pathological conditions. Moreover, it is also critical for the development of therapeutic interventions. In 1902, the anatomist Florence Sabin published her studies on the development of the earliest lymphatic vessels in pigs [1 ] and thereby laid the foundation for a c...
3D+T echocardiography is a valuable tool for assessing cardiac function, as it enables real-time, non-invasive and low cost acquisition of volumetric images of the heart. The automated tracking of heart chambers in 3D+T echocardiography remains a challenging task due to reasons including speckle noise, shadowing, and the existence of intra-cavity structures [6]. Furthermore, the real-time detec...
Attempts to produce in animals conditions resembling various rheumatic diseases have been numerous and have employed a wide variety of agents. Such work has usually had as its object the investigation of the part played by a certain factor in the causation of rheumatic conditions or the provision of animal subjects to test the efficacy of therapeutic agents. The work reported here was undertake...
Vaccine derived poliovirus (VDPV) type 2 strains strongly divergent from the corresponding vaccine strain, Sabin 2, were repeatedly isolated from sewage in Slovakia over a period of 22 months in 2003-2005. Cell cultures of stool specimens from known immune deficient patients and from an identified putative source population of 500 people failed to identify the potential excretor(s) of the virus...
Type 1 wild-vaccine recombinant polioviruses sharing a 367-nucleotide (nt) block of Sabin 1-derived sequence spanning the VP1 and 2A genes circulated widely in China from 1991 to 1993. We surveyed the sequence relationships among 34 wild-vaccine recombinants by comparing six genomic intervals: the conserved 5'-untranslated region (5'-UTR) (nt 186 to 639), the hypervariable portion of the 5'-UTR...
