Widespread Bathyarchaeia encode a novel methyltransferase utilizing lignin‐derived aromatics

mLife, Volume 2, Issue 3, Page 272-282, September 2023., 2023
Abstract Lignin degradation is a major process in the global carbon cycle across both terrestrial and marine ecosystems. Bathyarchaeia, which are among the most abundant microorganisms in marine sediment, have been proposed to mediate anaerobic lignin degradation. However, the mechanism of bathyarchaeial lignin degradation remains unclear.

Modeling Multi‐Fraction Coastal Aeolian Sediment Transport With Horizontal and Vertical Grain‐Size Variability

Journal of Geophysical Research: Earth Surface, Volume 128, Issue 7, July 2023., 2023
Abstract Grain size affects the rates of aeolian sediment transport on beaches. Sediment in coastal environments typically consists of multiple grain‐size fractions and exhibits spatiotemporal variations. Still, conceptual and numerical aeolian transport models are simplified and often only include a single fraction that is constant over the model ...

Monsoons, Upwelling, and the Deoxygenation of the Northwestern Indian Ocean in Response to Middle to Late Miocene Global Climatic Shifts

Paleoceanography and Paleoclimatology, Volume 35, Issue 2, February 2020., 2020
Abstract Today, upwelling along the Oman margin in the Arabian Sea is governed by the South Asian Monsoon winds. The Oman upwelling results in the formation of an oxygen minimum zone (OMZ) spanning across the Arabian Sea and large parts of the Indian Ocean.

Clinical Efficacy of Oral Mesalazine in Crohn’s Disease

Canadian Journal of Gastroenterology and Hepatology, Volume 4, Issue 1, Page 13-18, 1990., 1990
A randomized controlled trial was performed to evaluate in Crohn′s disease the clinical efficacy and safety of a higher dose of a new slow‐release preparation of mesalazine (500 mg tablets). Twenty‐four patients created with 3 g mesalazine/day were compared with 26 patients treated with sulfasalazine (3 g/day) and methylprednisolone (initially 40 mg ...
