Abstract Background Patients with injection drug use (IDU) have increased risk of developing infective endocarditis (IE). Previous studies reported recurrent IE, duration hospital stay, poor adherence and compliance as well higher mortality worse outcomes after surgery in the IDU-IE patient group. Further are needed to provide a basis for optimized care prevention readmissions this population. ...

Wadi El-Hitan, the UNESCO World Heritage Site, of the Fayum Depression in the northeast part of the Western Desert of Egypt, has produced a remarkable collection of Eocene vertebrates, in particular the fossil whales from which it derives its name. Here we describe a new genus and species of marine catfishes (Siluriformes; Ariidae), Qarmoutus hitanensis, from the base of the upper Eocene Birket...

Oxidative stress, the physiological condition whereby the production of reactive oxygen and nitrogen species overwhelms the capacity of antioxidant defences, causes damage to key bio-molecules. It has been implicated in many diseases, and is proposed as a reliable currency in the trade-off between individual health and ornamentation. Whether oxidative stress mediates the expression of carotenoi...

Few ankylosaurs are known from more than a single specimen, but the ankylosaurid Euoplocephalus tutus (from the Late Cretaceous of Alberta, Canada and Montana, USA) is represented by dozens of skulls and partial skeletons, and is therefore an important taxon for understanding intraspecific variation in ankylosaurs. Euoplocephalus is unusual compared to other dinosaurs from the Late Cretaceous o...

Tags made of mudstone are predominantly found in ancient Egyptian Predynastic cemetery contexts. This study examines the symbolism and significance tags with recurved horns hartebeests crescent-shaped tags. The use syncretic imagery on these provides evidence for fluidity artistic perceptions Egypt. Available data suggests that individuals buried hartebeest crescent were almost exclusively fema...

The present study was carried out to characterize the cervical mucus (CM) collected when inseminating Holstein cows and to relate the secretion pattern with pregnancy. The mucus was collected from mid-cervix of 64 cows with spontaneus estrus (SE) and induced estrus (IE). The quantity, pattern and consistency of the mucus, pH, arborization patterns and the sperm motility were observed. The level...
