Analysis of the Alterations in Symbiotic Microbiota and Their Correlation with Intestinal Metabolites in Rainbow Trout (Oncorhynchus mykiss) Under Heat Stress Conditions

open access: yesAnimals
Global warming represents one of the most pressing environmental challenges to cold-water fish farming. Heat stress markedly alters the mucosal symbiotic microbiota and intestinal microbial metabolites in fish, posing substantial barriers to the healthy ...

Exercise and Training at Altitudes: Physiological Effects and Protocols

open access: yesRevista Ciencias de la Salud, 2014
An increase in altitude leads to a proportional fall in the barometric pressure, and a decrease in atmospheric oxygen pressure, producing hypobaric hypoxia that affects, in different degrees, all body organs, systems and functions.

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

open access: yesFEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

open access: yesFEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

Comparative Adaptive Mechanisms of Two Indigenous Goat Genetic Resources Under Simulated Water Scarcity

open access: yesAnimals
Water scarcity is a major constraint to livestock production in tropical and semi-arid environments, necessitating the identification of breeds with superior adaptive capacity.

Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Decision-making for climate change adaptation: A systems thinking approach [PDF]

open access: yes, 2013
The impacts of climate change are exacerbated by inefficient adaptation and mitigation decision making, due to the complexity of the decision-making environment. As a consequence, there is no single approach to planning and decision making.

Preliminary Data Regarding the Physiological State of Alosa immaculata (Bennett, 1835) During Spawning Migration

open access: yesAquaculture, Fish and Fisheries
Reproductive migration in anadromous fish involves complex physiological adjustments to support intense metabolic and reproductive demands. In the case of Alosa immaculata, a key migratory species of the lower Danube River, these adaptations can be ...
