Deep-sea Ordovician lingulide brachiopods and their associated burrows suggest an early colonization of proximal turbidite systems

Abstract Trace fossils from Ordovician deep-marine environments are typically produced by a shallow endobenthos adapted to live under conditions of food scarcity by means of specialized grazing, farming, and trapping strategies, preserved in low-energy intermediate to distal zones of turbidite systems.High-energy proximal zones have been considered

Host Cells of Leucocytozoon (Haemosporida, Leucocytozoidae) Gametocytes, with Remarks on the Phylogenetic Importance of This Character

Leucocytozoon parasites remain poorly investigated in comparison to other haemosporidians.The host cell inhabited by their blood stages (gametocytes) remains insufficiently known.This study aimed to determine the blood cells inhabited by Leucocytozoon Nails gametocytes in different species of Passeriformes and to test if this feature has a phylogen

Almanac 2012: Cardiovascular risk scores. The national society journals present selected research that has driven recent advances in clinical cardiology

Global risk scores use individual level information on non-modifiable risk factors (such as age, sex, ethnicity and family history) and modifiable risk factors (such as smoking status and blood pressure) to predict an individual’s absolute risk of an adverse event over a specified period of time in the future.Cardiovascular risk Adapters scores h
