First VLBI mapping of circumstellar 29SiO maser emission
We report the first VLBI map of the v=0 J=1-0 maser line of 29SiO in the
long-period variable star IRC+10011. We have found that this maser emission is
composed of multiple spots distributed in an incomplete ring, suggesting that
this maser is also amplified tangentially, as already proposed in other SiO
circumstellar masers. We present also VLBI maps for the 7 mm 28SiO v=1 and 2
J=1-0 and the 3 mm v=1 J=2-1 lines. The 29SiO masing region appears to be
located in a layer in between the 28SiO v=1 J=1-0 and 28SiO v=1 J=2-1 lines. In
addition, we confirm that the 86 GHz maser v=1 J=2-1 forms in an outer region
of the circumstellar envelope compared to the other 28SiO masers studied.
Finally, we discuss the possible implications of the observational results on
the SiO maser pumping theory.Comment: 4 pages, 2 figures. Accepted for publication in A&A Letter
Dense gas in the dust lane of Centaurus A
The interstellar medium of Centaurus A (NGC 5128) has been studied
extensively in recent years, using mostly molecular lines tracing low to medium
density gas (500 to several cm). The amount and distribution of
the dense molecular gas was largely unknown. Here we present new millimeter
data of the HCN(1-0), CS(2-1), and CS(3-2) rotational transitions towards the
nearby radio galaxy Centaurus A observed with the SEST on La Silla, Chile. We
obtained spectra of the HCN(1-0) emission which traces dense 10 cm
molecular gas at the center and along the prominent dust lane at offset
positions and . We also
obtained a few spectra of CS(2-1) and (3-2) tracing densities of
cm. The emission in these lines is weak and reaches a few mK at the
available angular resolutions of 54 - 36.
At the central position, the integrated intensity ratio I(HCN)/I(CO) peaks at
0.064, and decreases to 0.02 to 0.04 in the dust lane.Comment: 7 pages, 5 figures, accepted by A.&A. 04. May 200

Propranolol in Infantile Hemangioma Treatment. Experience in 2 Cases
Introdução: O Hemangioma infantil é o tumor benigno mais frequente na idade pediátrica. A maioria tem evolução favorável, no entanto dependendo da sua localização, podem levar à distorsão de estruturas anatómicas ou a outras complicações locais ou sistémicas, tornando necessária uma abordagem terapêutica precoce e eficaz. Neste contexto, desde que Léauté-Labréze e colaboradores publicaram a sua experiência com o propranolol em 2008, têm-se multiplicado na literatura internacional, casos clínicos e pequenas séries em que este fármaco é utilizado “off-label” como terapêutica de primeira linha. O presente trabalho visa reportar a experiência de um
serviço na utilização de propranolol como terapêutica de primeira linha no tratamento do hemangioma infantil em 2 doentes.
Casos clínicos: O doente 1, do sexo feminino, tinha um hemangioma infantil desde as 5 semanas, localizado na pirâmide nasal. O doente 2, do sexo masculino, tinha dois hemangiomas infantis ulcerados: um localizado na face, com atingimento do mento, lábio inferior, mucosa gengival e labial; um segundo de localização escrotal. Ambos os doentes realizaram indução terapêutica com propranolol em regime de internamento com uma dose alvo de 2 a 3 mg/Kg/dia. Ao fim de 6 meses de follow-up, assistiu-se a uma resposta muito satisfatória, sem complicações
documentadas.
Discussão: O propranolol constitui uma alternativa segura e eficaz no tratamento do hemangioma. Embora não tenham ocorrido complicações, elas estão descritas e ocorrem principalmente durante a fase de indução terapêutica, tornando importante a monitorização durante esse período
Information technology and the transformation of mass societies. Information technology today
International audienceThe goal is to analyze the formation and content of the notion of Information Society (Joho shakai). The point is that it needs to be understood not as a technology but as part of techno-industrial system in the sense of Bertrand Gille and Gilbert Simondon.La notion de "société de l'information" ne désigne pas une technologie générique qui en serait l'infrastructure mais l'émergence d'un nouveau système technique, tel que Bertrand Gille et Gilbert Simondon permettent de le penser et analyser
