Abstract Asymptotic giant branch stars create a rich inventory of molecules in their envelopes as they lose mass during later stages evolution. These cannot survive the conditions interstellar space, where are exposed to ultraviolet photons radiation field. As result, daughter ones injected into and halo those is predicted exist around cool evolved stars. The most abundant molecule other than H...

We report the detection of the elusive carbon-chain radical C 5 N in the dark cloud TMC1 and its tentative detection in the circumstellar envelope IRC+10216. C 5 N appears to be two orders of magnitude less abundant than the related molecule HC 5 N and much less abundant than expected from current gas phase chemistry models. In comparison the HC 3 N to C 3 N abundance ratio is of the order of 1...

[email protected] En los pacientes con IRC, los mecanismos que pueden explicar las elevaciones inespecíficas de TnIc son principalmente el mayor daño cardíaco y la función renal disminuida5. En nuestro estudio, las principales causas de elevación de TnIc en el grupo Otras Patologías Cardíacas (OPC) fueron la insuficiencia cardíaca congestiva, fibrilación auricular y taquicardia, mientras que en e...

Silicon-bearing species Si2Hx (x = 1–6) are probable candidates in the circumstellar envelope of IRC+10216. We have observed several fundamentals of new silicon-containing radicals Si2H3 and Si2H5 in addition to the well-known Si2H4 and Si2H6 species from infrared spectroscopy in low temperature silane matrices at 10 K. Several infrared bands identify the Si2Hx species and can be used to search...

Background Recanalization of cerebral large‐vessel occlusions (LVOs) by intravenous thrombolysis is infrequent but has been relatively unexplored with ultraearly treatment. We evaluated prehospital treatment tissue plasminogen activator (tPA) in a mobile stroke unit to explore the recanalization rate patients LVOs and its effect on early clinical improvement long‐term disability. Methods Prospe...
