La amistad de los animales como denuncia en contra del parasitismo en la Historia de los Animales de Claudio Eliano

open access: yesRevista Ciencias y Humanidades, 2018
La amistad es un tema capital en la historia del pensamiento occidental. Ella representó para algunos filósofos grecolatinos uno de los bienes más valiosos para la vida de los hombres, pues la amistad contribuye a la vida buena o la vida feliz.

Ten Key Insights into the Use of Spinal Cord fMRI

open access: yesBrain Sciences, 2018
A comprehensive review of the literature-to-date on functional magnetic resonance imaging (fMRI) of the spinal cord is presented. Spinal fMRI has been shown, over more than two decades of work, to be a reliable tool for detecting neural activity.

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.

Detecting Emerging Diseases in Farm Animals through Clinical Observations

open access: yesEmerging Infectious Diseases, 2006
Predicting emerging diseases is among the most difficult challenges facing researchers and health managers. We present available approaches and tools to detect emerging diseases in animals based on clinical observations of farm animals by veterinarians ...

Mitochondrial fatty acid oxidation is stimulated by red light irradiation

open access: yesFEBS Letters, EarlyView.
Light at different wavelengths has distinct effects on keratinocyte viability and metabolism. UVA light abrogates metabolic fluxes. Blue and green light have no effect on metabolic fluxes, while red light enhanced oxidative phosphorylation by promoting fatty acid oxidation. Keratinocytes are the primary constituents of sunlight‐exposed epidermis.

ANIMAL IMAGES IN GEORG TRACKL’S POETRY

open access: yesJuvenis Scientia, 2019
The article analyzes the images of animals in lyrical works of the famous Austrian expressionist poet Georg Trakl. Animals are the representatives of the biological kingdom of the same name. The images of mammals, as well as the images of insects, birds,

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.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
