Mercury (Hg) and persistent organic pollutant (POP) accumulation among species and biomagnification through food webs is typically assessed using stable isotopes of nitrogen (δN) and carbon (δC) in bulk (whole) tissues. Yet, bulk isotopic approaches have limitations, notably from the potential overlap of isotope values from different dietary sources and from spatial variation in source (baseline) signals. Here, we explore the potential of fatty acid carbon isotopes (FA δC) to (1) evaluate the trophic structure of a marine food web, (2) distinguish feeding patterns among four marine mammal consumers, (3) trace contaminant biomagnification through a food web, and (4) explain interspecific variation in contaminants among high-trophic position predators.

Background: Registry-based data are increasingly used in dermatological research. A recent epidemiological study has shown that the use of non-specific diagnostic codes is common among dermatologists.
Objectives: To study closely the use of the diagnostic codes L23.

Unlabelled: Intrinsic capacity and quality of life of older adults are determined by many factors, including the functional state of the organ of vision.
Purpose: This study assessed the visual functions of elderly residents of Northern European Russia and examined the relationship between visual impairment and sociodemographic characteristics, ophthalmic conditions, and preservation of work capacity and social functions.
Material And Methods: This cross-sectional study included a random population sample of older adults (ages 60-74) from Arkhangelsk, Russia (=604).

Light environment in the Arctic differs widely with the seasons. Studies of relationships between objectively measured circadian phase and amplitude of light exposure and melatonin in community-dwelling Arctic residents are lacking. This investigation combines cross-sectional (n = 24-62) and longitudinal (n = 13-27) data from week-long actigraphy (with light sensor), 24-h salivary melatonin profiles, and proxies of metabolic health.

The equine bloodworm, Strongylus vulgaris, is a common and highly pathogenic parasite in horses due to its migratory life cycle involving the intestinal arteries. Current diagnostic techniques cannot detect the prepatent migrating stages of S. vulgaris, highlighting the need for new biomarkers.
