The association of serum choline concentrations with the risk of cancers: a community-based nested case–control study

Scientific Reports, 2023
Few studies have been designed to investigate the effect of serum choline on the risk of incident cancer. This study aims to explore the association between serum choline and the risk of new-onset cancer.

Methemoglobin determination by multi-component analysis in coho salmon (Oncorhynchus kisutch) possessing unstable hemoglobin

MethodsX, 2020
Hemoglobin derivatives are often quantified in blood to establish cardio-respiratory status and possible causes of impaired oxygen transport. The derivative known as methemoglobin results from oxidation of hemoglobin and is pathologically relevant ...

A Qualitative Study on Engaged Families’ Experiences with Long-Term Follow-Up Care in the Colorado/Wyoming Newborn Screening System

International Journal of Neonatal Screening
Understanding whether the long-term follow-up (LTFU) system is working for families is critical to measuring the success of newborn screening (NBS) and understanding why some families are lost to follow-up.

Photoprotective Strategies of Mediterranean Plants in Relation to Morphological Traits and Natural Environmental Pressure: A Meta-Analytical Approach

Frontiers in Plant Science, 2017
Despite being a small geographic extension, Mediterranean Basin is characterized by an exceptional plant biodiversity. Adaptive responses of this biocoenosis are delineated by an unusual temporal dissociation along the year between optimal temperature ...

How competitive is drought deciduousness in tropical forests? A combined eco-hydrological and eco-evolutionary approach

Environmental Research Letters, 2017
Drought-deciduous and evergreen species are both common in tropical forests, where there is the need to cope with water shortages during periodic dry spells and over the course of the dry season. Which phenological strategy is favored depends on the long-
