Spatial Scale Matters: Hydrolysis of Aryl Methyl Ethers over Zeolites.

The local environment of the active site, such as the confinement of hydronium ions within zeolite pores, significantly influences catalytic turnover, similar to enzyme functionality. This study explores these effects in the hydrolysis of guaiacols─lignin-derived compounds─over zeolites in water. In addition to the interesting catechol products, this reaction is advantageous for study due to its bimolecular hydrolysis pathway, which involves a single energy barrier and no intermediates, simplifying kinetic studies and result interpretation.

Methods: A Working Group of experts including members of the ESC Clinical Practice Guidelines Task Force for ACS, Acute CardioVascular Care Association and European Association of Percutaneous Cardiovascular Interventions followed the ESC methodology for QI development.

The Role of Multimodality Imaging in Multiple Valvular Heart Diseases. A Clinical Consensus Statement of the European Association of Cardiovascular Imaging (EACVI) of the ESC.

With this document, the European Association of Cardiovascular Imaging (EACVI) provides an Expert Consensus on the role of multi-modality imaging (MMI) in the management of patients with multiple valvular heart disease (MVD).

Risk characterization of organic micropollutants in public wastewater treatment plant effluents in Flanders, Belgium.

This study investigates the ecological risks posed by organic micropollutants (OMPs) in wastewater treatment plant (WWTP) effluents in Flanders, Belgium based on single-compound risk characterization. Utilizing a five-year monitoring dataset from the Flemish Environment Agency (VMM) and employing seven ecological threshold values (ETV) types, this research characterizes the risk of 207 OMPs, including pharmaceuticals, pesticides, industrial chemicals, and other pollutants. Several OMPs persist in effluents at concentrations that pose significant ecological risks after secondary and tertiary treatment processes in the region of Flanders (Belgium).

Pulmonary vascular complications of cirrhosis: hepatopulmonary syndrome and portopulmonary hypertension.

Hepatopulmonary syndrome (HPS) and portopulmonary hypertension (POPH) are two distinct pulmonary vascular complications seen in patients with liver disease and/or portal hypertension. HPS is characterized by disturbed gas exchange and hypoxemia because of intrapulmonary vascular dilatations. POPH is defined by pulmonary arterial hypertension, which might lead to right heart failure.

Biodiversity within phytoplankton-associated microbiomes regulates host physiology, host community ecology, and nutrient cycling.

Unlabelled: Biological diversity is declining across the tree of life, including among prokaryotes. With the increasing awareness of host-associated microbes as potential regulators of eukaryotic host physiology, behavior, and ecology, it is important to understand the implications of declining diversity within host microbiomes on host fitness, ecology, and ecosystem function. We used phytoplankton and their associated environmental microbiomes as model systems to test the independent and interactive effects of declining microbiome diversity with and without other stressors often caused by human activity-elevated temperature and altered nutrient availability.

Our study aimed to assess these abnormalities in non-IBD individuals and compare them with IBD patients in endoscopic remission to identify the associated factors.

Simulation of adaptive immune receptors and repertoires with complex immune information to guide the development and benchmarking of AIRR machine learning.

Machine learning (ML) has shown great potential in the adaptive immune receptor repertoire (AIRR) field. However, there is a lack of large-scale ground-truth experimental AIRR data suitable for AIRR-ML-based disease diagnostics and therapeutics discovery. Simulated ground-truth AIRR data are required to complement the development and benchmarking of robust and interpretable AIRR-ML methods where experimental data is currently inaccessible or insufficient.

Mammary Gland Reactive Stroma Characterization at Aging After Bisphenol A Exposure During Hormonal Susceptibility Windows.

Mammary glands development is influenced by endocrine signaling, which remodels epithelial and stromal compartments. Reactive stroma phenotype is observed when stromal disturbances occur, leading to changes in extracellular matrix composition and occurrence of reactive cell types. One of the triggers of these alterations is endocrine-disrupting chemical exposure, such as bisphenol A (BPA).

Evaluation of phenotypic risk indicators for the development of alopecia X (hair cycle arrest) in Pomeranian dogs in the Netherlands and Belgium.

Background: Alopecia X (AX) is a common noninflammatory alopecic condition of Pomeranian dogs with an unknown cause. While a genetic aetiology is suspected, no current tests can predict the development of this disorder or confirm the aetiology. Therefore, identifying potential risk indicators for the development of AX would be of value in this breed.
