Radiologic, Histologic and Scanning Electron Microscopic Characterization of the Peritoneal Reflection in Crohn's Disease

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The peritoneal reflection bridges visceral and parietal peritoneum and lacks adjoining or underlying organs. As such it provides an opportunity to perform a focussed examination of the peritoneum in Crohn's disease. The aim of this study was to exploit this anatomical property and conduct a multilayered, focussed examination of the peritoneal ...

Neutron and proton tests of different technologies for the upgrade of the cold readout electronics of the ATLAS Hadronic End-cap Calorimeter

open access: yes, 2011
The expected increase of total integrated luminosity by a factor ten at the HL-LHC compared to the design goals for LHC essentially eliminates the safety factor for radiation hardness realized at the current cold amplifiers of the ATLAS Hadronic End-cap ...

Click Capture SELEX for the Identification of Click‐Modified Aptamers Targeting Small Molecules in Solution

open access: yesChemistry – A European Journal, EarlyView.
Using kanamycin A as a model target, we developed click‐capture SELEX to identify nucleobase‐modified aptamers capable of binding small molecules in solution. This approach enables flexible incorporation of nucleobase modifications via CuAAC, allowing the chemical properties of the aptamer to be tailored to the target molecule.

Integrated Selective Depolymerization and Downstream Processing for Mixed Polyester Waste, Part 1

open access: yesChemie Ingenieur Technik, EarlyView.
Chemical recycling of mixed plastics by hydrolysis generates dilute monomer mixtures requiring complex downstream purification. To overcome this challenge, upstream selectivity is targeted. Tailored reaction conditions enable cascaded depolymerization which is shown for a PLA/PET model system.

PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana

open access: yesCytoskeleton, EarlyView.
ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.

Analysis and Characterization of Kisspeptin and Its Analogues in Serum and Urine Samples by Liquid Chromatography–High‐Resolution Mass Spectrometry for Doping Control Purposes

open access: yesDrug Testing and Analysis, EarlyView.
Sensitive LC‐HRMS methods were established for the detection of kisspeptin and its analogues in serum and urine, alongside their analytical and metabolic characterization. Stability studies were conducted in serum, plasma, and urine, highlighting the importance of appropriate sample handling for reliable anti‐doping analysis.

Iben Nagel Rasmussen: transparency in the maturity

open access: yesRevista Brasileira de Estudos da Presença, 2022
Transparency is proposed as a quality that emerges from the career of the actress Iben Nagel Rasmussen, a representative of a laboratory dimension, of work on oneself in the European theater.

The impact of forced closure on proppant distribution of hydraulic fracturing in shale formations

open access: yesDeep Underground Science and Engineering, EarlyView.
Research findings demonstrate that implementing forced closure within shale formations can remarkably mitigate proppant settlement, concurrently increasing the effective propped surface area from 29.74% to 38.68%. Abstract Forced closure is widely used in conventional oil and gas reservoirs to promote uniform proppant placement.
