Physiological and Genetic Basis of High-Altitude Indigenous Animals’ Adaptation to Hypoxic Environments

open access: yesAnimals
Adaptation is one of the fundamental characteristics of life activities; humans and animals inhabiting high altitudes are well adapted to hypobaric hypoxic environments, and studies on the mechanisms of this adaptation emerged a hundred years ago.

Avoid, attack or do both? Behavioral and physiological adaptations in natural enemies faced with novel hosts

open access: yesBMC Evolutionary Biology, 2005
Background Confronted with well-defended, novel hosts, should an enemy invest in avoidance of these hosts (behavioral adaptation), neutralization of the defensive innovation (physiological adaptation) or both?

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

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.

Explaining bathymetric diversity patterns in marine benthic invertebrates and demersal fishes: physiological contributions to adaptation of life at depth

open access: yes, 2014
Bathymetric biodiversity patterns of marine benthic invertebrates and demersal fishes have been identified in the extant fauna of the deep continental margins.

Evaluation of hemato-biochemical parameters in Ouled Djellal sheep: influence of age, sex, and body weight on individual variability

open access: yesJournal of Scientific Research in Science
This study evaluates the hematological and biochemical parameters of Ouled Djellal sheep in the Tébessa region, eastern Algeria, by analyzing the impact of age, sex, and weight on these parameters.

Metastatic niche shaped by host factors influences disseminated cancer cell fate

open access: yesFEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Supporting evidence-based adaptation decision-making in the Australian Capital Territory: a synthesis of climate change adaptation research [PDF]

open access: yes, 2013
This research synthesis provides policy-makers and practitioners with an understanding of the building blocks for effective adaptation decision-making, as evidenced through the NCCARF research program.

DNA ligase LigE increases bacterial transformation with damaged extracellular DNA

open access: yesFEBS Letters, EarlyView.
The DNA ligase LigE from the naturally competent Gram‐negative bacterium Neisseria gonorrhoaea increases transformation with cut extracellular DNA. This process is ATP‐dependent and relies on the catalytic activity of LigE; it also requires that LigE contains an intact periplasmic localisation sequence, indicating that ligE functions in the periplasm ...
