Notes on the Guidelines of the 2009 Online Workshop on Theories of Consciousness

open access: yesScripta, 2022
The Online Workshop on Theories of Consciousness (OWTC), a set of live online (text only) discussions carried out in 2009 at the site Nature.com, was an attempt to organize and find minimal agreement on the epistemological bases for scientific and ...

The envenomation of general physiology throughout the last century. [PDF]

open access: yes, 2017
Toxins are the poisonous products of organisms. Toxins serve vital defensive and offensive functions for those that harbor them: stinging scorpions, pesticidal plants, sanguinary snakes, fearless frogs, sliming snails, noxious newts, and smarting spiders.

Temperature increase and its effects on fish stress physiology in the context of global warming.

open access: yesJournal of Fish Biology, 2020
The capacity of fishes to cope with environmental variation is considered to be a main determinant of their fitness and is partly determined by their stress physiology.

Photosynthesis under far‐red light—evolutionary adaptations and bioengineering of light‐harvesting complexes

open access: yesFEBS Letters, EarlyView.
Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.

Somatosensory processing in long COVID fatigue and its relations with physiological and psychological factors

open access: yesExperimental Physiology
Fatigue is prevalent amongst people with long COVID, but is poorly understood. The sensory attenuation framework proposes that impairments in sensory processing lead to heightened perception of effort, driving fatigue.

Exploring the Influence of Planting Densities and Mulching Types on Photosynthetic Activity, Antioxidant Enzymes, and Chlorophyll Content and Their Relationship to Yield of Maize

open access: yesPlants
High-density maize cultivation can enhance yield, but water scarcity on the Loess Plateau may limit this potential. Mulching is a sustainable practice that conserves soil moisture, yet limited studies exist on the combined effects of planting densities ...

The role of fibroblast growth factors in cell and cancer metabolism

open access: yesFEBS Letters, EarlyView.
Fibroblast growth factor (FGF) signaling regulates crucial signaling cascades that promote cell proliferation, survival, and metabolism. Therefore, FGFs and their receptors are often dysregulated in human diseases, including cancer, to sustain proliferation and rewire metabolism.

Levels of shading and application of glyphosate and carfentrazone-ethyl in the control of Macroptilium atropurpureum

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental
Variations in environmental conditions, such as the availability of light, can affect the efficacy of herbicides because they alter the biological characteristics of plants including those that are related to the plant’s sensitivity to herbicides ...

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots

open access: yesFEBS Letters, EarlyView.
This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...
