Ariadnema polymorpha gen. et sp. nov. (Scytonemataceae, Cyanobacteria): A new heterocytous cyanobacterium with true and false branching from ruins in the Brazilian Atlantic Forest

Journal of Phycology, EarlyView.
Abstract A novel heterocytous Cyanobacterium, Ariadnema polymorpha gen. et sp. nov., was observed in the northern Brazilian Atlantic Forest (BAF), a globally significant biodiversity hotspot that has microbiome diversity yet to be explored.

A convenient approach to (-)-8-epi-swainsonine

, 2007
A novel and efficient synthesis of (-)-8-epi-swainsonine 2 is reported. Face selective diol formation from the bicyclic alkene 3 followed by a stereoselective vinylation of the aldehyde and ring closing metathesis gave the indolizidine ring system which ...

Periodontal Salutogenesis: Why Are Some People Resistant to Oral Microbial Dysbiosis and Destructive Inflammation?

Journal of Periodontal Research, EarlyView.
Emerging evidence suggests that periodontal health is not simply the absence of disease, but the result of a dynamic interaction between biological resilience, healthy lifestyles, adaptive coping mechanisms, and supportive environments. This results in a strong sense of coherence, which is not only a psychological state but also a biological state ...

Laterally Oscillating Trajectory for Undersampling Slices: LOTUS. [PDF]

Magn Reson Med
ABSTRACT Purpose While spiral sampling offers SNR advantages for diffusion MRI, its acceleration with simultaneous multislice remains relatively unexplored. This study introduces Laterally Oscillating Trajectory for Undersampling Slices (LOTUS), which is a 3D spiral‐like k‐space trajectory that aims to minimize g‐factor via controlled incoherent ...

The Diremption of Meaning

Modern Theology, EarlyView.
