FUSE observations of the central star of Abell 78 [PDF]
arXiv, 2002 FUSE high resolution spectra of two PG1159 type central stars (K1-16 and NGC 7094) have revealed an unexpected iron deficiency of at least 1 or 2 dex (Miksa et al. 2002). Here we present early results of FUSE spectroscopy of the CSPN Abell 78. It is shown that iron is strongly deficient in this star, too.

Iron Deficiency Anemia in Inflammatory Bowel Disease
Journal of Education, Health and SportInflammatory bowel disease (IBD) is a chronic inflammatory disease of the gastrointestinal tract. It includes Crohn's disease (CD) and ulcerative colitis (UC). It occurs with periods of exacerbations and remissions.

Metal abundances in PG1159 stars from Chandra and FUSE spectroscopy [PDF]
arXiv, 2002 We investigate FUSE spectra of three PG1159 stars and do not find any evidence for iron lines. From a comparison with NLTE models we conclude a deficiency of 1-1.5 dex. We speculate that iron was transformed into heavier elements. A soft X-ray Chandra spectrum of the unique H- and He-deficient star H1504+65 is analyzed.

Eurasian Journal of Medicine, 2011 Objective: Iron deficiency anemia is the most common cause of microcytic anemia throughout the world. Ferritin levels are good indicators of iron stores; however, levels may increase irrespective of iron stores in cases of chronic disease.

Improved parameters of the hydrogen-deficient binary star KSPer [PDF]
arXiv, 2008 Using the high resolution spectral observations obtained with the Nasmyth Echelle Spectrograph NES of the 6m telescope we analysed the optical spectrum of the hydrogen-deficient binary star KSPer. The atmospheric parameters derived are: effective temperature Teff=9500+/-300 K, surface gravity log g=2.0+/-0.5, and microturbulent velocity Vt=9.5+/-0.5km ...

Hematology, Transfusion and Cell Therapy, 2018 Background: Refractory or unexplained iron deficiency anemia accounts for about 15% of all cases. The endoscopic gastrointestinal workup sometimes fails to establish the cause of iron deficiency anemia and a considerable proportion of patients regardless

Haematologica, 2018 The detection of iron deficiency anemia is challenged by the paucity of diagnostic tests demonstrating high sensitivity and specificity. Using two biomarkers, zinc-protoporphyrin/heme and hepcidin, we established the diagnostic cut-off values for iron ...

UV and FUV spectroscopy of the hybrid PG 1159-type central star NGC 7094 [PDF]
arXiv, 2008 Previous studies aiming at the iron-abundance determination in three PG 1159 stars (K 1-16, PG 1159-035, NGC 7094) and a [WC]-PG 1159 transition star (Abell 78) have revealed that no object shows any iron line in the UV spectrum. The stars are iron-deficient by at least 1 dex, typically.
