Neutrophil-Lymphocyte, Platelet-Neutrophil, and Platelet-Lymphocyte Ratios as Indicators of Sickle Cell Anaemia Severity.

Background: Sickle cell anaemia (SCA) imposes a substantial healthcare burden, affecting millions of people worldwide. Understanding the determinants influencing SCA severity is crucial for enhanced disease management and optimized patient outcomes. This study aimed to investigate the relationship between Neutrophil-Lymphocyte Ratio (NLR), Platelet-Neutrophil Ratio (PNR), Platelet-Lymphocyte Ratio (PLR), and SCA severity.

Atlantic salmon Salmo salar in the chalk streams of England are genetically unique.

Recent research has identified genetic groups of Atlantic salmon Salmo salar that show association with geological and environmental boundaries. This study focuses on one particular subgroup of the species inhabiting the chalk streams of southern England, U.K.

The origins of Atlantic salmon (Salmo salar L.) recolonizing the River Mersey in northwest England.

By the 1950s, pollution had extirpated Atlantic salmon in the river Mersey in northwest England. During the 1970s, an extensive restoration program began and in 2001, an adult salmon was caught ascending the river. Subsequently, a fish trap was installed and additional adults are now routinely sampled.
