Climate change and temperature dependent biogeography: oxygen limitation of thermal tolerance in animals [PDF]

open access: yes, 2001
Recent years have shown a rise in mean global temperatures and a shift in the geographical distribution of ectothermic animals. For a cause and effect analysis the present paper discusses those physiological processes limiting thermal tolerance.

Modification of pyruvate kinase and lactate dehydrogenase in foot muscle of the sea mussel Mytilus galloprovincialis under anaerobiosis and recovery

open access: yesBrazilian Journal of Medical and Biological Research, 1997
The modification of pyruvate kinase (PK) and lactate dehydrogenase (LDH) activity in foot muscle of the mussel Mytilus galloprovincialis during exposure to air and recovery in water was investigated.

The Many Facets of Hypoxia in Plants

open access: yesPlants, 2020
Plants are aerobic organisms that require oxygen for their respiration. Hypoxia arises due to the insufficient availability of oxygen, and is sensed by plants, which adapt their growth and metabolism accordingly.

ArxA From Azoarcus sp. CIB, an Anaerobic Arsenite Oxidase From an Obligate Heterotrophic and Mesophilic Bacterium

open access: yesFrontiers in Microbiology, 2019
Arsenic is a toxic element widely distributed in nature, but numerous bacteria are able to resist its toxicity mainly through the ars genes encoding an arsenate reductase and an arsenite efflux pump.

Involvement of ethylene signalling in a non-climacteric fruit: new elements regarding the regulation of ADH expression in grapevine [PDF]

open access: yes, 2004
Although grape berries have been classified as non climacteric fruits, ongoing studies on grape ethylene signalling lead to challenge the role of ethylene in their ripening. One of the significant molecular changes in berries is the up regulation of ADH

Differential Gene Expression of Mucor lusitanicus under Aerobic and Anaerobic Conditions

open access: yesJournal of Fungi, 2022
Mucor lusitanicus and some other members of the fungal order Mucorales display the phenomenon of morphological dimorphism. This means that these fungi aerobically produce filamentous hyphae, developing a coenocytic mycelium, but they grow in a multipolar

Salt Stress Induces Imbalanced ADI Pathway Gene Expressions in Pediococcus acidilactici Drives Citrulline Accumulation as an Ethyl Carbamate Precursor in Soy Sauce

open access: yesFood Bioengineering, EarlyView.
ABSTRACT Citrulline is the main precursor of a carcinogen compound ethyl carbamate (EC) in soy sauce. Accumulation of citrulline is mainly related to metabolism of arginine by Pediococcus acidilactici via the arginine deiminase (ADI) pathway during soy sauce fermentation.

Electrolyzed saline as an alternative to chlorhexidine: Antimicrobial and biofilm volume outcomes in a 4‐day non‐brushing randomized controlled clinical trial

open access: yesJournal of Periodontology, EarlyView.
Abstract Background The biofilm‐inhibitory effects of electrolyzed saline (EOS) vary widely due to differences in formulations and treatment methods. This study analyzed the impact of EOS on key oral microbial species and used serial 3D‐intraoral scans to evaluate its effects on de novo biofilm formation.
