The value of the Hubble Deep Field to study of the remote regions of the observable Universe is difficult to overstate, as the many exciting results of this workshop are ample testament. However, an added bonus of the HDF is that, although it a very narrow angle survey, the depth of the HDF results in its sampling a significant volume of the halo of our galaxy. Thus it is useful for the purpose...

High dosages of intra-operative remifentanil are associated with opioid-induced hyperalgesia (OIH). The aim of the present study was to investigate the effect of combined dexmedetomidine and flurbiprofen axetil treatment on remifentanil-induced hyperalgesia. Patients with an American Society of Anesthesiologists physical status of I-II who were diagnosed with hysteromyoma and scheduled for lapa...

We present an analysis of the evolution of galaxy clustering in the redshift interval 0 ≤ z ≤ 4.5 in the HDF-South. The HST optical data are combined with infrared ISAAC/VLT observations, and photometric redshifts are used for all the galaxies brighter than IAB ≤ 27.5. The clustering signal is obtained in different redshift bins using two different approaches: a standard one, which uses the bes...

Background Compared to high-flux dialysis membranes, novel medium cut-off (MCO) membranes show greater permeability for larger middle molecules. Methods In two prospective, open-label, controlled, randomized, crossover pilot studies, 39 prevalent hemodialysis (HD) patients were studied in four dialysis treatments as follows: study 1, three MCO prototype dialyzers (AA, BB and CC with increasin...

We present results from a 479.7 ks Chandra exposure of the Hubble Deep Field North (HDF-N) and its immediate vicinity. In our X-ray image, the deepest ever reported with a 0.5–2.0 keV flux limit of ≈ 4.9 × 10 −17 erg cm −2 s −1 , we detect four new HDF-N X-ray sources bringing the total number of such sources to 12. The new sources include two optically bright (R = 18.3–18.8), low-redshift (z <...

We present a catalog of 74 galaxies detected serendipitously during a campaign of spectroscopic observations of the Hubble Deep Field North (HDF) and its environs. Among the identiÐed objects are Ðve candidate Lya emitters at a galaxy cluster at z\ 0.85, and a Chandra source with a heretofore z Z 5, undetermined redshift of z\ 2.011. We report redshifts for 25 galaxies in the central HDF, 13 of...

ASTRONOMY AND ASTROPHYSICS AGN and starbursts at high redshift: High resolution EVN radio observations of the Hubble Deep Field. Abstract. We present deep, wide-field European VLBI Network (EVN) 1.6 GHz observations of the Hubble Deep Field (HDF) region with a resolution of 0.025 arcseconds. Above the 210 µJy/beam (5σ) detection level, the EVN clearly detects two radio sources in a field that e...

We present catalogues of faint 1.4-GHz radio sources from extremely-deep Very Large Array pointings in the Lockman Hole, the Hubble Deep Field North (HDF-N) and ELAIS N2. Our analysis of the HDF-N data has produced maps that are significantly deeper than those previously published and we have used these to search for counterparts to submm sources. For each of the fields we have derived normalis...

Mimicking the biological function of the extracellular matrix is an approach to developing cell adhesive biomaterials. The RGD peptide, derived from fibronectin (Fn), mainly binds to integrin αvβ3 and has been widely used as a cell adhesive peptide on various biomaterials. However, cell adhesion to Fn is thought to be mediated by several integrin subtypes and syndecans. In this study, we synthe...
