Regulation of Choroid Plexus Bicarbonate Transporters Following Intraventricular Hemorrhage in Mice

Cell Biochemistry and Function, Volume 44, Issue 3, March 2026.
ABSTRACT Posthemorrhagic hydrocephalus is a severe complication to intraventricular hemorrhage. The condition results in enlarged brain ventricles and increased intracranial pressure due to accumulation of cerebrospinal fluid (CSF). In this study, two mouse models of intraventricular hemorrhage were investigated: injection of lysed red blood cells ...

SMC-Last Extracted Photometry

The Astronomical Journal
We present point-source photometry from the Spitzer Space Telescope's final survey of the Small Magellanic Cloud (SMC). We mapped nearly 30 deg ^2 in two epochs in 2017, with the second extending to early 2018 at 3.6 and 4.5 μ m using the Infrared Array ...

The Spectral Energy Distributions and Bolometric Luminosities of Local AGN: Study of the Complete 12 μm AGN Sample

The Astrophysical Journal
We measure the bolometric luminosity of a complete and unbiased 12 μ m-selected sample of active galactic nuclei (AGN) in the local Universe. For each galaxy, we used a 10-band radio-to-X-ray spectral energy distribution (SED) to isolate the genuine AGN ...

Long-term infrared photometry of Seyferts [PDF]

Monthly Notices of the Royal Astronomical Society, 2004
Long-term (up to 10 000 d) monitoring has been undertaken for 41 Seyferts in the near-infrared (1.25–3.45 μm). All but two showed variability, with amplitudes at K in the range 1.1 mag. The time-scale for detectable change is from about one week to a few years.

An infrared study of galactic OH/IR stars. I. An optical/near-IR atlas of the Arecibo sample

, 2004
In this paper we present optical and near-infrared finding charts, accurate astrometry (~1") and single-epoch near-infrared photometry for 371 IRAS sources, 96% of those included in the so-called Arecibo sample of OH/IR stars (Eder et al.

Dazzle: Oversampled Image Reconstruction and Difference-imaging Photometry for the Nancy Grace Roman Space Telescope

The Astronomical Journal
We present algorithms and software for constructing high-precision difference images to detect and measure transients, such as microlensing events, in crowded stellar fields using the Nancy Grace Roman Space Telescope.

Infrared photometry of UV Piscium

Astrophysics and Space Science, 1987
The eclipsing binary system UV Psc was observed in the near-infrared (JHK), and a wave-like distortions have been observed similar to those in the visible. The out-of-eclipse observations have shown real large amount of scatter. This cannot be attributed to the existence of spots on one of the components, which can explain the wave-like distorition of ...

Monitoring luminous yellow massive stars in M33: new yellow hypergiant candidates

, 2017
The evolution of massive stars surviving the red supergiant (RSG) stage remains unexplored due to the rarity of such objects. The yellow hypergiants (YHGs) appear to be the warm counterparts of post-RSG classes located near the Humphreys-Davidson upper ...

The effects of dust on the optical and infrared evolution of SN 2004et

, 2011
We present an analysis of multi-epoch observations of the Type II-P supernova SN 2004et. New and archival optical spectra of SN 2004et are used to study the evolution of the Halpha and [O I] 6300A line profiles between days 259 and 646.
