Cold comfort for change: Stream mats as biological indicators of ecosystem processes in the McMurdo Dry Valleys, Antarctica

Journal of Phycology, EarlyView.
Abstract Glacier‐fed streams (GFSs) make ideal systems for studying climate‐related changes. Some of the best‐studied GFSs are found in the McMurdo Dry Valleys (MDVs) of Antarctica, one of the Earth's coldest and driest deserts. Despite their harsh and isolated nature, MDV GFSs represent an oasis of life in a landscape visually devoid of it, with ...

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Gut Microbiota‐Derived Extracellular Vesicles in Patients With Obesity Undergoing Gastric Bypass Surgery

Molecular Microbiology, EarlyView.
Extracellular vesicles (EVs) have been suggested to participate in gut microbiota–host communication. While obesity and bariatric surgery have been shown to alter the gut microbiota composition, changes in gut microbiota‐EVs have not been investigated.

Inflammatory Bowel Disease in Children and Young People Living With Overweight or Obesity: A Critical Narrative Review

Obesity Reviews, EarlyView.
ABSTRACT Inflammatory bowel disease is a chronic inflammatory disorder affecting the gastrointestinal tract. It mainly comprises of Crohn's disease and ulcerative colitis. Its global prevalence has risen simultaneously with overweight and obesity among children and young people over the last decades.

Associations of Adiposity With Gut Microbiota Composition Among Adults—Results From a Federated Analysis of Individual Participant Data From Eight European Observational Studies

Obesity Reviews, EarlyView.
ABSTRACT Gut microbiota may contribute to the adiposity‐associated disease risk, but human studies reported inconsistent associations of adiposity with gut microbiota composition. We examined associations of body mass index (BMI) with alpha diversity and relative microbial abundance at the phylum and genus taxonomic levels (based on 16S rRNA amplicon ...

Phyllosphere Keystone Beneficial Specialists Enhance Yield in Nutrient Deficiency‐Resistant Sorghum Cultivars

Plant, Cell &Environment, EarlyView.
ABSTRACT The phyllosphere, the aboveground interface between plant leaves and their microbial residents, plays a vital yet underappreciated role in crop productivity. While root‐ and soil‐associated microbiomes are well‐studied, the ecological assembly and yield‐related effects of host‐mediated phyllosphere microbial communities remain largely ...

Investigation of 222‐nm ultraviolet C irradiation bactericidal effect on the surgical field in a rabbit model

Photochemistry and Photobiology, EarlyView.
In a rabbit surgical field model seeded with polymicrobial flora, a single dose of 222‐nm UV‐C (500 mJ/cm2) markedly reduced bacterial colonies, achieving a bactericidal effect comparable to 254‐nm UV‐C (200 mJ/cm2), while no UV‐C irradiation showed heavy growth. Wound healing did not differ among groups. Microbiota profiling detected SSI‐relevant taxa
