“Physiology in extreme conditions” was concerned with two main issues: (a) to increase knowledge about individual reactions and mechanisms of adaptations in specific extreme environmental conditions; (b) to widen the analytical skills gap created by data generated in extremely severe conditions, and in response to pathological disorders. A wide spectrum of topics was proposed by the included ar...

Non-structural carbohydrates (NSC) affect tree growth and survival when photosynthesis is impacted by climate change, such as seasonal drought extreme precipitation. Nevertheless, it still unclear whether Eucalyptus suffers limitation under natural conditions if trees recover artificial cultivation. In present study, we conducted a field control experiment to compare the NSC storage in urophyll...

UNLABELLED The use of ocular prostheses for ophthalmic patients aims to rebuild facial aesthetics and provide an artificial substitute to the visual organ. Natural intemperate conditions promote discoloration of artificial irides and many studies have attempted to produce irides with greater chromatic paint durability using different paint materials. OBJECTIVES The present study evaluated the...

1. Four groups of rat pups were reared: mother-reared (MR) control (well-fed) and undernourished (MRC and MRU respectively) and artificially reared (AR) control and undernourished (ARC and ARU respectively). Pups for artificial rearing were fitted with a gastric cannula on postnatal day 5 and were fed, by intermittent gastric infusion, expressed rats' milk (days 5-7), mixtures of rats' milk and...

Newand old-world tropical electric fish lack a common electrical ancestor, suggesting that the mechanisms of signal generation and recognition evolved independently in the two groups. Recent research on convergent designs for electrogenesis and electroreception has focused on the structure of electric organs, the neural circuitry controlling the pacemaker driving the electric organ, and the neu...

Artificial intelligence-enhanced skin-like sensors based on flexible nanogenerators have been widely used in physiological signal acquisition, artificial organ, sensory simulation, human movement status recognition, and other biomedical related fields due to their excellent biocompatibility, comfortable wearing experience, high sensing accuracy, low power consumption. In this paper, the working...

The development of a variety of new biomedical and bioinspired mechatronic systems poses challenges that share the need for innovative technologies for electromechanical transduction, so as to enable applications not feasible or even imaginable with conventional approaches. To address this need, new technologies based on electromechanically active polymer (EAP) transducers are progressively eme...

“Epigenetic Tracking” is an evo-devo method to generate arbitrary 2d or 3d shapes; as such, it belongs to the field of “artificial embryology”. In silico experiments have proved the effectiveness of the method in devo-evolving any kind of shape, of any complexity (in terms of number of cells, number of colours, etc.); being shape complexity a metaphor for organismal complexity, such simulations...

abstract background: studies have shown that, with regard to social, cultural, and institutional contexts, several factors affect family decision-making on organ donation. this study aimed to investigate the effective factors in organ donation by family members with brain-dead patients. materials and methods: this was a descriptive-comparative study in which a researcher-made questionnaire was ...
