Fat/Water Separation at 7 T Using a 3D Radial Sequence With Quasi‐Continuous Echo Times

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To achieve a reliable fat/water separation (FWS) at 7 T using a new 3D radial sequence and reconstruction workflow with quasi‐continuous TE sampling. Methods A 3D radial density‐adapted sequence with quasi‐continuous TE sampling was developed for a 7 T whole‐body MRI system.

Glycemic control and renal function decline in patients with chronic coronary syndrome: A multicenter cohort study

Journal of Diabetes Investigation, EarlyView.
Achieving HbA1c of 6.5–6.9% is associated with a reduced risk of renal complications in patients with diabetes and chronic coronary syndrome. Abstract Aims/Introduction Diabetes mellitus significantly contributes to renal complications, especially in patients with coronary artery disease (CAD).

Life in The Context of Order and Complexity

Life, 2020
It is generally accepted that life requires structural complexity. However, a chaotic mixture of organic compounds like the one formed by extensive reaction sequences over time may be extremely complex, but could just represent a static asphalt-like dead

Toward a Biosignature for Suicide [PDF]

American Journal of Psychiatry, 2014
Suicide, a major cause of death worldwide, has distinct biological underpinnings. The authors review and synthesize the research literature on biomarkers of suicide, with the aim of using the findings of these studies to develop a coherent model for the biological diathesis for suicide.The authors examined studies covering a large range of ...

Simultaneous characterization of the atmospheres, surfaces, and exomoons of nearby rocky exoplanets

Earth and Planetary Physics, 2018
Atmospheric composition is an important indicator of habitability and life. The presence or absence of a large exomoon around an Earth-size exoplanet could have important consequences for planet climate stability.

Microbially generated ferruginous crusts: A potential biosignature of continental input in coastal settings

Sedimentology, EarlyView.
ABSTRACT Thin ferruginous sandy crusts are common on top of sandstone beds in the Early Permian post‐glacial deposits of the Paraná Basin in southern Brazil. These crusts usually preserve wrinkle structures, suggesting that they might be a product of microbial mediation.

Development of Holocene lacustrine microbialites on the Iberian Peninsula: Insights into environmental and depositional controls using X‐ray CT and petrography

Sedimentology, EarlyView.
ABSTRACT Microbial mats and microbialites are common in modern and ancient saline lacustrine environments and are highly responsive to biological and environmental factors. As such, they represent important sources of high‐resolution environmental data across a wide range of geological time. Nonetheless, interpretation of fossil mats is non‐trivial due

Biosignatures Associated with Freshwater Microbialites [PDF]

Life, 2020
Freshwater microbialites (i.e., lithifying microbial mats) are quite rare in northern latitudes of the North American continent, with two lakes (Pavilion and Kelly Lakes) of southeastern BC containing a morphological variety of such structures. We investigated Kelly Lake microbialites using carbon isotope systematics, phospholipid fatty acids (PLFAs ...
