Progress in detection of and correction for low-energy contamination.

Contamination with low-energy radiation leads to an increased number of weighted residuals being larger in absolute terms than three standard uncertainties. For a Gaussian distribution, these rare events occur only in 0.27% of all cases, which is a small number for small- to medium-sized data sets.

Choosing a treatment method for post-catheterization pseudoaneurysms guided by the late to early velocity index.

Ultrasound-guided thrombin injection (UGTI) is often the first-line treatment for iatrogenic post-catheterization pseudoaneurysms (psA). There are also first reports of the use of biologically derived tissue glues (TG) instead of sole thrombin especially when UGTI was unsuccessful or in case of psA recurrence. Previously, we have established that a late to early velocity index (LEVI) < 0.

On the accuracy and precision of X-ray and neutron diffraction results as a function of resolution and the electron density model.

X-ray diffraction is the main source of three-dimensional structural information. In total, more than 1.5 million crystal structures have been refined and deposited in structural databanks (PDB, CSD and ICSD) to date.

Analysis of major otosclerosis-associated variants in and genes in Polish patients.

Introduction: Otosclerosis (OTSC) is one of the most common causes of progressive adult-onset hearing loss in the Caucasian population, with a female preponderance. The etiology of OTSC is complex and there are a number of genetic variants reported to be associated with OTSC susceptibility, but no data on the genetic background of OTSC in patients originating from the central-eastern part of Europe have been available. The purpose of our study was to investigate in Polish patients the frequency of genetic variants previously reported to be most strongly associated with OTSC.

Diferrocenyl Thioketone: Reactions with (Bisphosphane)Pt(0) Complexes-Electrochemical and Computational Studies.

Diferrocenyl thioketone reacts smoothly with (bisphosphane)Pt(0) complexes in toluene solution at room temperature yielding 1:1 adducts identified as ferrocenyl (Fc) functionalized platinathiiranes. Their structures were unambiguously confirmed by means of spectroscopic methods as well as by X-ray diffraction analysis. A unique, ferrocene-rich platinathiirane, bearing three Fc-units, was prepared starting with [bis(diphenylphosphino)ferrocene] Pt(0(-norbornene).
