Characteristics of Subgingival Plaque Microbiome in Japanese Older Adults With Healthy Gingiva

Journal of Clinical Periodontology, Volume 52, Issue 9, Page 1314-1326, September 2025.
ABSTRACT Aim To elucidate the characteristics of the subgingival plaque microbiome in older adults without gingival inflammation. Materials and Methods Subgingival plaque from 180 participants was collected and analysed using 16S rRNA sequencing. Based on the clinical parameters at the sampling sites, participants were categorised as healthy (gingival ...

Photosynthetic impact of hypoxia on in hospite zooxanthellae in the scleractinian coral Pocillopora damicornis [PDF]

, 2005
Shallow water coral reefs may experience hypoxia under conditions of calm weather doldrums. Anaerobic responses of endosymbionts (i.e. zooxanthellae) within Pocillopora damicornis coral colonies were tested using both slow and fast chlorophyll a ...

Ornithine-catalyzed urea formation in liver homogenate [PDF]

, 1947
Heretofore attempts to obtain synthesis of urea from ammonia (and carbon dioxide) in cell-free extracts have been unsuccessful. We have found the reaction to proceed in guinea pig liver homogenate.

Dark Anaerobic Conditions Induce a Fast Induction of the Xanthophyll Cycle in Chlamydomonas reinhardtii When Exposed to High Light

Microorganisms
Background: Dark anaerobiosis promotes the acidification of the thylakoid lumen and a reduction in the plastoquinone (PQ) pool. The relationship between the reduction in the PQ pool in the dark and the induction of the xanthophyll cycle under high light ...

The thermodynamic landscape of carbon redox biochemistry [PDF]

, 2018
Redox biochemistry plays a key role in the transduction of chemical energy in all living systems. Observed redox reactions in metabolic networks represent only a minuscule fraction of the space of all possible redox reactions.
