Results are presented for [C ii] 158μm line fluxes observed with the Herschel PACS instrument in 112 sources with both starburst and active galactic nucleus (AGN) classifications, of which 102 sources have confident detections. Results are compared with mid-infrared spectra from the Spitzer Infrared Spectrometer and with Lir from IRAS fluxes; AGN/starburst classifications are determined from eq...
We report CS J=7→6, HCN J=4→3, and HCO J=4→3 observations in 20 nearby star-forming galaxies with the Acatama Pathfinder EXperiment 12-m telescope. Combined with 4 CS, 4 HCN, and 3 HCO detections in literature, we probe the empirical link between the luminosity of molecular gas (L′gas) and that of infrared emission (LIR), up to the highest gas densities (106 108cm−3 ) that have been probed so f...
We present the most complete study to date of the X-ray emission from star formation in high-redshift (median z= 0.7; z < 1.5), IR-luminous (LIR = 1010–1013 L ) galaxies detected by Herschel’s PACS and SPIRE instruments. For our purpose, we take advantage of the deepest X-ray data to date, the Chandra Deep Fields (North and South). Sources which host AGN are removed from our analysis by means o...
BACKGROUND AND PURPOSE CHOP is a C/EBP family transcription factor involved in endoplasmic reticulum (ER) stress-mediated apoptosis. Several studies have demonstrated that ischemia reperfusion results in apoptosis. Oxidative stress is central to ischemia reperfusion-induced apoptosis. Taurine protects against lung injury after limb ischemia reperfusion (LIR) through antioxidation. The effects o...
We present the most complete study to date of the X-ray emission from star formation in high-redshift (median z= 0.7; z < 1.5), IR-luminous (LIR = 10 –10 L⊙) galaxies detected by Herschel’s PACS and SPIRE instruments. For our purpose, we take advantage of the deepest X-ray data to date, the Chandra Deep Fields (North and South). Sources which host AGN are removed from our analysis by means of m...
We explore the behaviour of [C ii]λ157.74μm forbidden fine-structure line observed in a sample of 28 galaxies selected from ∼ 50 deg of the H-ATLAS survey. The sample is restricted to galaxies with flux densities higher than S160μm > 150mJy and optical spectra from the GAMA survey at 0.02 < z < 0.2. Far-IR spectra centred on this redshifted line were taken with the PACS instrument on-board the ...
Several autophagy proteins contain an LC3-interacting region (LIR) responsible for their interaction with Atg8 homolog proteins. Here, we show that ALFY binds selectively to LC3C and the GABARAPs through a LIR in its WD40 domain. Binding of ALFY to GABARAP is indispensable for its recruitment to LC3B-positive structures and, thus, for the clearance of certain p62 structures by autophagy. In add...
We report the results of a Spitzer infrared study of the Cosmic Eye, a strongly lensed, L∗UV Lyman Break Galaxy (LBG) at z = 3.074. We obtained Spitzer IRS spectroscopy as well as MIPS 24 and 70 μm photometry. The Eye is detected with high significance at both 24 and 70 μm and, when including a flux limit at 3.5 mm, we estimate an infrared luminosity of LIR = 8.3 +4.7 −4.4 × 10 11 L⊙ assuming a...
OBJECTIVE To elucidate the value of early computed tomographic (CT) signs of stroke in predicting the occlusion site in the cerebral arteries. PATIENTS 105 consecutive patients with acute embolic stroke affecting the anterior circulation. METHODS Four early signs were evaluated on cranial CT within six hours of stroke onset: loss of the insular ribbon (LIR); attenuation of the lentiform nuc...
INTRODUCTION We aimed to understand the changes in cartilage lubricin expression and immunolocalisation in responsed to treadmill running with different intensities in a rat model. METHODS A total of 24 male Wistar rats were randomly assigned into groups of control (CON), low-intensity running (LIR), moderate-intensity running (MIR), and high-intensity running (HIR). Rats in LIR, MIR, and HIR...
