Bioelectrochemical Stimulation of Electromethanogenesis at a Seawater-Based Subsurface Aquifer in a Natural Gas Field

Frontiers in Energy Research, 2019
In subsurface anoxic environments, microbial communities generally produce methane as an end-product to consume organic compounds. This metabolic function is a source of biogenic methane in coastal natural gas aquifers, submarine mud volcanoes, and ...

A widely distributed metalloenzyme class enables gut microbial metabolism of host- and diet-derived catechols. [PDF]

, 2020
Catechol dehydroxylation is a central chemical transformation in the gut microbial metabolism of plant- and host-derived small molecules. However, the molecular basis for this transformation and its distribution among gut microorganisms are poorly ...

The Interface of Oral and Brain Health: Current Insights Into the Bidirectional Relationship Between Alzheimer's Disease and Periodontitis

CNS Neuroscience &Therapeutics, Volume 32, Issue 1, January 2026.
Bidirectional Pathogenesis Between AD and Periodontitis. Periodontal pathogens reach the brain via hematogenous/trigeminal/oral–intestinal pathways, triggering neuroinflammation and Aβ plaques to drive AD. Conversely, AD disrupts bone homeostasis (via Aβ, endocrine/autonomic dysregulation) to aggravate periodontitis.

Quality Analysis and Detection of Adulterants and Contaminations in Milk/Milk Powder by Raman Spectroscopy

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 1, January 2026.
ABSTRACT Milk and milk powder are central to global nutrition, yet remain vulnerable to adulteration and contamination. Adulteration using water, urea, ammonium sulfate, thiocyanates, detergents, melamine, or compositional changes with whey and carbohydrate fillers undermines nutritional quality, reduces consumer confidence, and challenges regulatory ...

Chronic Low‐Level Lead Exposure Causes Auditory Impairment and Accelerates the Progression of Age‐Related Hearing Loss in C57BL/6J Mice

Aging Cell, Volume 25, Issue 1, January 2026.
Chronic low‐concentration lead exposure accelerates the development of ARHL. Lead exposure mediates damage to cochlear sensory cells via the mitochondrial protease LONP1, leading to irreversible hearing loss. ABSTRACT Heavy metal ion exposure has become a global public health concern.

Stress Nutrition in Aquatic Animals: From Definition to Practice

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Aquaculture faces numerous challenges, with stress being one of the major issues that lead to growth loss, metabolic disorders, weakened immunity, redox imbalance, and organ damage in aquatic animals. Nutritional intervention is one of the effective strategies to address these problems. Traditional research has primarily focused on the impacts
