Enhanced Microbial Sensing via Resazurin Reduction Catalyzed by Graphene Oxide, A Versatile Approach for Diagnostics and Electrochemical Applications

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Resazurin is a cell viability phenoxazine dye widely employed for bacterial monitoring, as its colorimetric and fluorometric conversion reflects microbial metabolic activity. In this work, we demonstrate that graphene oxide (GO), a two‐dimensional nanomaterial with high surface reactivity, markedly accelerates the reduction of resazurin in the

High‐Altitude Adaptation of Frogs (Case Study: Nanorana parkeri): From Physiological Phenotypes to AltitudeOmics

open access: yesIntegrative Zoology, EarlyView.
High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.

Effects of temperature and carbon source on the isotopic fractionations associated with O_2 respiration for ^(17)O/^(16)O and ^(18)O/^(16)O ratios in E. coli [PDF]

open access: yes, 2018
^(18)O/^(16)O and ^(17)O/^(16)O ratios of atmospheric and dissolved oceanic O_2 are used as biogeochemical tracers of photosynthesis and respiration. Critical to this approach is a quantitative understanding of the isotopic fractionations associated with

New Allergens Approved by the WHO/IUIS Allergen Nomenclature Sub‐Committee in 2021–2024 and Their Significance for Future Diagnostics, Regulation, and Research. An EAACI Task Force Report

open access: yesAllergy, EarlyView.
ABSTRACT The WHO/IUIS Allergen Nomenclature Sub‐Committee is an international body of experts that maintains the systematic nomenclature of allergenic proteins by assigning official names to newly identified allergens submitted by researchers. Here, we summarize the data on new allergens approved between 2021 and 2024.

INSL3 Expression in Leydig Cells is a Biomarker for Immunocastration in Boars: Transcriptional Evidence

open access: yesAndrology, EarlyView.
ABSTRACT Background Study aimed to obtain insights into physiological responses to immunocastration in pubertal boars by evaluating effects of alternative vaccination protocols and identifying a reliable immunocastration biomarker. Objectives It was hypothesized that the timing of gonadotropin‐releasing hormone (GnRH) suppression by immunocastration ...

Denitrification by rhizobia: A possible factor contributing to nitrogen losses from soils [PDF]

open access: yes, 1980
The intensive pastoral farming system on which New Zealand animal production is based is almost completely dependent upon the rhizobium-legurne symbiosis for the fixed nitrogen required for pasture production.

Anti‐inflammatory effects of physical stimuli: The central role of networks in shaping the future of pharmacological research

open access: yesBritish Journal of Pharmacology, EarlyView.
Addressing complexity in the study of life sciences through Systems Biology and Systems Medicine has been transformative, making Systems Pharmacology the next logical step. In this review, we focus on physical stimuli, whose potential in pharmacology has been neglected, despite demonstrated therapeutic properties.

Distribution and activity of nitrate and nitrite reductases in the microbiota of the human intestinal tract

open access: yesThe FEBS Journal, EarlyView.
Nitrate from food is first converted to nitrite by oral bacteria and then further processed in the intestine. The gut microbiota reduces nitrate and nitrite to ammonia or nitric oxide, preventing the formation of carcinogenic nitrosamines. Our analysis highlights Escherichia coli as a key player in this detoxification process, supported by other ...
