Article Abstract
Oligonucleotides carrying 3'-terminal phosphates and conjugates are important tools in molecular biology and diagnostic purposes. We described the preparation of solid supports carrying the base labile linker 4-((2-hydroxyethyl)sulfonyl)benzamide for the solid-phase synthesis of 3'-phosphorylated oligonucleotides. These supports are fully compatible with the phosphoramidite chemistry yielding the desired 3'-phosphate oligonucleotides in excellent yields. The use of mild deprotection conditions allows the generation of partially protected DNA fragments.

Evaluating Posterior Vitreous Detachment Annotation Consistency on OCT Scans in Patients with Disease of the Vitreomacular Interface.

Department of Ophthalmology, Inselspital, Bern University Hospital, University of Bern, Freiburgstrasse 15, CH-3010.
Purpose: To evaluate inter-grader variability in posterior vitreous detachment (PVD) classification in patients with epiretinal membrane (ERM) and macular hole (MH) on spectral-domain optical coherence tomography (SD-OCT) and identify challenges in defining a reliable ground truth for artificial intelligence (AI)-based tools.
Methods: A total of 437 horizontal SD-OCT B-scans were retrospectively selected and independently annotated by six experienced ophthalmologists adopting four categories: 'full PVD', 'partial PVD', 'no PVD', and 'ungradable'. Inter-grader agreement was assessed using pairwise Cohen's kappa scores.

Wrist biomechanics remain incompletely understood due to the complexity of experimental measurements in this multi-bone joint system. Finite element analysis provides a powerful alternative for investigating internal variables such as carpal kinematics and displacement patterns. This technical brief compares two bone representation approaches, all-cortical versus cortical-trabecular, using two distinct finite element models developed from the same wrist CT dataset.

A method for determination of ten kinds of sweeteners in soybean products by multi-plug filtration cleanup (-PFC) combined with ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was established. The sample was extracted with acetonitrile (containing 1% formic acid), degreased by using -hexane liquid-liquid extraction and purified by solid phase extraction using an -PFC column (Oasis PRiME HLB). The analytes were separated by using a Waters ACQUITY UPLC® BEH C (2.

Although ammonia-oxidizing archaea (AOA) are globally distributed in nature, growth in biofilms has been relatively little explored. Here we investigated six representatives of three different terrestrial and marine clades of AOA in a longitudinal and quantitative study for their ability to form biofilm, and studied gene expression patterns of three representatives. Although all strains grew on a solid surface, soil strains of the genera Nitrosocosmicus and Nitrososphaera exhibited the highest capacity for biofilm formation.

The supported catalytically active liquid metal solution (SCALMS) concept is based on catalytically active metals dissolved in a low-melting-point liquid metal matrix. These solid alloy particles, deposited over a high area support, transform into a liquid alloy under reaction conditions. In this work, GaPt SCALMS materials of varying composition are investigated and focus on the change in the alloy composition during preheating, the actual high temperature propane dehydrogenation at 823 K, and after cool-down.
