All-in-one 2LabsToGo system for analysis of ergot alkaloids in whole rye.

Ergot alkaloids, naturally occurring mycotoxins of Claviceps fungi, pose health risks. This necessitates accurate analysis methods to ensure food safety. This study explored the open-source miniaturized all-in-one 2LabsToGo system to analyze ergot alkaloids in whole rye samples.

Direct Coupling of Methane and Carbon Dioxide on Tantalum Cluster Cations.

Understanding molecular-scale reaction mechanisms is crucial for the design of modern catalysts with industrial prospect. Through joint experimental and computational studies, we investigate the direct coupling reaction of CH and CO , two abundant greenhouse gases, mediated by Ta ions to form larger oxygenated hydrocarbons. Coherent with proposed elementary steps, we expose products of CH dehydrogenation [Ta CH ] to CO in a ring electrode ion trap.

Mass-Spectrometry-Based Lipidome and Proteome Profiling of (Scorpiones: Buthidae) Venom.

Scorpion venom is a complex secretory mixture of components with potential biological and physiological properties that attracted many researchers due to promising applications from clinical and pharmacological perspectives. In this study, we investigated the venom of the Iranian scorpion (Simon, 1880) by applying mass-spectrometry-based proteomic and lipidomic approaches to assess the diversity of components present in the venom. The data revealed that the venom's proteome composition is largely dominated by Na- and K-channel-impairing toxic peptides, following the enzymatic and non-enzymatic protein families, e.

Changes in Endocan and Dermatan Sulfate Are Associated with Biomechanical Properties of Abdominal Aortic Wall during Aneurysm Expansion and Rupture.

Background And Aims:  The study aimed to assess the potential of proteoglycans (PGs) and collagens as serological biomarkers in the abdominal aortic aneurysm (AAA). Furthermore, we investigated the underlying mechano-biological interactions and signaling pathways.

Methods:  Tissue and serum samples from patients with ruptured AAA (rAAA;  = 29), elective AAA (eAAA;  = 78), and healthy individuals ( = 8) were evaluated by histology, immunohistochemistry, and enzyme-linked immunosorbent assay, and mechanical properties were assessed by tensile tests.

A new sea-level record for the Neogene/Quaternary boundary reveals transition to a more stable East Antarctic Ice Sheet.

Sea-level rise resulting from the instability of polar continental ice sheets represents a major socioeconomic hazard arising from anthropogenic warming, but the response of the largest component of Earth's cryosphere, the East Antarctic Ice Sheet (EAIS), to global warming is poorly understood. Here we present a detailed record of North Atlantic deep-ocean temperature, global sea-level, and ice-volume change for ∼2.75 to 2.
