Fertimetro, a Principle and Device to Measure Soil Nutrient Availability for Plants by Microbial Degradation Rates on Differently-Spiked Buried Threads [PDF]

open access: yes, 2018
A novel patented method (PCT/IB2012/001157: Squartini, Concheri, Tiozzo, University of Padova) and the corresponding application devices, suitable to measure soil fertility, are presented. The availability or deficiency of specific nutrients for crops is

Exploring metabolic dysfunction in chronic kidney disease [PDF]

open access: yes, 2012
Impaired kidney function and chronic kidney disease (CKD) leading to kidney failure and end-stage renal disease (ESRD) is a serious medical condition associated with increased morbidity, mortality, and in particular cardiovascular disease (CVD) risk ...

IMPACT OF NONPATHOGENIC MICROBIAL BURDEN OF FEED ON THE HEALTH OF LABORATORY RATS

open access: yesZernovì Produkti ì Kombìkorma
Compound feeds provide nutritious and favorable environment for microorganisms, which can affect animal health during feeding. Microorganisms can interact with the animal’s normal gut microbiota and its own body, affecting the processes of feed digestion

The kynurenine pathway and the brain: challenges, controversies and promises [PDF]

open access: yes, 2017
Research on the neurobiology of the kynurenine pathway has suffered years of relative obscurity because tryptophan degradation, and its involvement in both physiology and major brain diseases, was viewed almost exclusively through the lens of the well ...

Mathematical Modeling of Transport and Degradation of Feedstuffs in the Small Intestine [PDF]

open access: yes, 2011
We describe a mathematical modeling of the digestion in the small intestine. The main interest of our work is to consider, at the same time, different aspects of the digestion i.e.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

The ecology of exercise: mechanisms underlying Individual variation in behavior, activity, and performance: an introduction to symposium [PDF]

open access: yes, 2017
Wild animals often engage in intense physical activity while performing tasks vital for their survival and reproduction associated with foraging, avoiding predators, fighting, providing parental care, and migrating.

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

open access: yesAdvanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

A reinforcement learning theory for homeostatic regulation [PDF]

open access: yes, 2011
Reinforcement learning models address animal’s behavioral adaptation to its changing “external” environment, and are based on the assumption that Pavlovian, habitual and goal-directed responses seek to maximize reward acquisition.
