The Chandra Deep Survey of the Hubble Deep Field North Area. IV. An Ultradeep Image of the HDF-N [PDF]

, 2001
We present results from a 479.7 ks Chandra exposure of the Hubble Deep Field North (HDF-N) and its immediate vicinity. In this X-ray image, the deepest ever reported with a 0.5–2.0 keV flux limit of ≈4.9 × 10-17 ergs cm-2 s-1, four new HDF-N X-ray ...

HDF promise for the future [PDF]

Nephrology Dialysis Transplantation, 2008
Sir, The February issue of Nephrology Dialysis Transplantation amply reported on online haemodiafiltration (HDF) as a possible promise for the future [1]. Please note the following erratum in Table 1 of the Editorial Comment, concerning our study with reference 16: high-volume HDF in postdilution was compared with high-flux haemodialysis (hfHD ...

Use of Amniotic Microparticles Coated with Fibroblasts Overexpressing SDF-1a to Create an Environment Conducive to Neovascularization for Repair of Full-Thickness Skin Defects

Cell Transplantation, 2016
As angiogenesis and vasculogenesis involve the complex network structures of various types of cells, extracellular matrix components, and cytokines, it is still difficult to exactly mimic the microenvironment of vascularization in vivo.

The AGN contribution to mid-infrared surveys. X-ray counterparts of the mid-IR sources in the Lockman Hole and HDF-N [PDF]

, 2001
We provide constraints on the AGN contribution to the mid-IR extragalactic background light from a correlation analysis of deep X-ray and mid-IR observations in two regions centred on the Lockman Hole and Hubble Deep Field North (HDF-N).

Autologous Extracellular Matrix‐Based Cell‐Free Therapy for Tissue Regeneration Through Trem2+ Macrophages Mediated Angiogenesis

Exploration, EarlyView.
ADF is prepared as a cell‐free bio‐membrane from autologous adipose ECM using simple physical techniques inspired by “papermaking”. It boasts superior properties and facilitates tissue regeneration through Trem2+ macrophages‐mediated angiogenesis. ADF can be stored long‐term for personalized medicine, offering insights into autologous ECM preservation ...

Persistent Mono‐Oxo Bonding with Protactinium(V) Revealed in Highly Acidic Chloride Solutions

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
Protactinium(V) defies expectations. Its elusive mono‐oxo bond was revealed through a combination of extended X‐ray absorption fine structure (EXAFS) and X‐ray absorption near‐edge structure (XANES) analyses, as well as quantum chemical calculations. This bond persists even in 12 M HCl.
