A Cost-Effective and Portable Optical Sensor System to Estimate Leaf Nitrogen and Water Contents in Crops

open access: yesSensors, 2020
Non-invasive determination of leaf nitrogen (N) and water contents is essential for ensuring the healthy growth of the plants. However, most of the existing methods to measure them are expensive.

Opportunities and limitations of crop phenotyping in southern european countries [PDF]

open access: yes, 2019
ReviewThe Mediterranean climate is characterized by hot dry summers and frequent droughts. Mediterranean crops are frequently subjected to high evapotranspiration demands, soil water deficits, high temperatures, and photo-oxidative stress.

Integrated immunoisolation and protein analysis of circulating exosomes using microfluidic technology [PDF]

open access: yes, 2014
Developing blood-based tests is appealing for non-invasive disease diagnosis, especially when biopsy is difficult, costly, and sometimes not even an option.

Right ventricular outflow tract velocity time integral-to-pulmonary artery systolic pressure ratio: a non-invasive metric of pulmonary arterial compliance differs across the spectrum of pulmonary hypertension. [PDF]

open access: yes, 2019
Pulmonary arterial compliance (PAC), invasively assessed by the ratio of stroke volume to pulmonary arterial (PA) pulse pressure, is a sensitive marker of right ventricular (RV)-PA coupling that differs across the spectrum of pulmonary hypertension (PH ...

Field phenotyping for African crops: overview and perspectives

open access: yesFrontiers in Plant Science, 2023
Improvements in crop productivity are required to meet the dietary demands of the rapidly-increasing African population. The development of key staple crop cultivars that are high-yielding and resilient to biotic and abiotic stresses is essential.

Impact of sternotomy and pericardiotomy on cardiopulmonary haemodynamics in a large animal model

open access: yesExperimental Physiology, 2023
Animal models of cardiovascular disease are often evaluated by invasive instrumentation for phenotyping. As no consensus exists, both open‐ and closed‐chest approaches are used, which might compromise rigour and reproducibility in preclinical research ...

Affordable Non-Invasive Machine-Aided Phenotyping Identifies Phenotypic Variation to Soil Stress Across the Arabidopsis thaliana Life Cycle. [PDF]

open access: yesPhysiol Plant
ABSTRACTArabidopsis thaliana is a model species for uncovering genetic adaptation to alkaline calcareous soils (ACS). This species thrives in ACS, often occurring in dry marginal and urban environments. Existing research largely focused on vegetatively grown seedlings, with a notable lack of studies examining phenotypic variations across the life cycle.
