IL‐4 induces cAMP and cGMP in human monocytic cells

open access: yesMediators of Inflammation, Volume 4, Issue 4, Page 298-305, 1995., 1995
Human monocytes, preincubated with IFN‐γ respond to IL‐4 by a cGMP increase through activation of an inducible NO synthase. Here, IL‐4 was found to induce an accumulation of cGMP (1 – 3 min) and cAMP (20 – 25 min) in unstimulated monocytes. This was impaired with NOS inhibitors, but also with EGTA and calcium/calmodulin inhibitors.

Precise measurements of optical Feshbach resonances of $^{174}$Yb atoms

open access: yes, 2016
We present precise measurements of the optical Feshbach resonances (OFRs) of $^{174}$Yb atoms for the intercombination transition. We measure the photoassociation (PA) spectra of a pure $^{174}$Yb Bose-Einstein condensate, and determine the dependence of

Global Observations of Acetyl Peroxynitrate (PAN) in the Remote Troposphere

open access: yesGeophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract We present global airborne observations of acetyl peroxynitrate (CH3C(O)OONO2, PAN) in the remote troposphere from the Atmospheric Tomography (ATom) campaign. These observations show that biomass burning is the dominant source of PAN in the Southern Hemisphere (SH).

Commutant Lifting for Commuting Row Contractions

open access: yes, 2009
If $T= \big[ T_1 ... T_n\big]$ is a row contraction with commuting entries, and the Arveson dilation is $\tilde T= \big[ \tilde T_1 ... \tilde T_n\big]$, then any operator $X$ commuting with each $T_i$ dilates to an operator $Z$ of the same norm which ...

O Tratado sobre a Proibição de Armas Nucleares (TPAN): inovação no desarmamento nuclear ou esforço inócuo?

open access: yesMeridiano 47 - Journal of Global Studies, 2019
O Tratado sobre a Proibição de Armas Nucleares (TPAN) foi aberto para assinaturas em 2017, e em outubro de 2019 o tratado tinha 79 signatários. No entanto, nenhum Estado Nuclearmente Armado assinou o tratado. Este artigo argumenta que o TPAN é tanto uma inovação no regime de não proliferação de armas nucleares quanto um tratado inadequado para atingir ...
