4 unusual facts about gamma-ray astronomy


Gamma-ray astronomy

The solar observations inspired theoretical work by Reuven Ramaty and others.

On June 19, 1988, from Birigüi (50° 20' W 21° 20' S) at 10:15 UTC a balloon launch occurred which carried two NaI(Tl) detectors (600 cm2 total area) to an air pressure altitude of 5.5 mb for a total observation time of 6 hr.

The most energetic photons (up to 16 TeV) observed from an extragalactic object originate from the blazar Markarian 501 (Mrk 501).

The highest photon energies measured to date are in the TeV range, the record being held by an "extraordinary outburst" of blazar Markarian 501 in 1997, yielding photons with as much as 16 TeV.

Influenza A virus subtype H2N3

Blood plasma levels of Interleukin 6 (IL-6), Interleukin 8, monocyte chemotactic protein-1 and Interferon-gamma were significantly increased in swine H2N3 compared to human H2N2 infected animals supporting the previously published notion of increased IL-6 levels being a potential marker for severe influenza infections.

Interleukin 10

IL-10 is capable of inhibiting synthesis of pro-inflammatory cytokines such as IFN-γ, IL-2, IL-3, TNFα and GM-CSF made by cells such as macrophages and regulatory T-cells.
