The cranium from the Octagon in Ephesos.

During excavations in 1929, a well-preserved skeleton was discovered in a sarcophagus in the Octagon at Ephesos (Turkey). For the following century, archaeologists have speculated about the identity of this obviously notable person. Repeated claim is that the remains could represent Arsinoë IV, daughter of Ptolemy XII, and younger (half-)sister of Cleopatra VII.

Cervidae antlers exploited to manufacture prehistoric tools and hunting implements as a reliable source of ancient DNA.

Antler is one of the primary animal raw materials exploited for technical purposes by the hunter-gatherer groups of the Eurasian Upper Palaeolithic (UP) all over the ecological range of deers, and beyond. It was exhaustively employed to produce one of the most critical tools for the survival of the UP societies: hunting weapons. However, antler implements can be made from diverse deer taxa, with different ecological requirements and ethological behaviours.

Shape variation in modern human upper premolars.

Morphological variation in modern human dentition is still an open field of study. The understanding of dental shape and metrics is relevant for the advancement of human biology and evolution and is thus of interest in the fields of dental anthropology, as well as human anatomy and medicine. Of concern is also the variation of the inner aspects of the crown which can be investigated using the tools and methods of virtual anthropology.

The difficult PICC insertion is associated with the significant increase of complications in 1 month follow-up.

Background: PICC is routinely inserted with assistance of ultrasonography and/or ECG navigation (RI- routine insertion). Only in a minority of patients the insertion of a PICC is difficult and fluoroscopic visualization with introduction of special guidewire is necessary for the success of the procedure (DI-difficult insertion). The aim of the study was to evaluate whether DI can be predicted and associated with a risk of complications during follow-up.

The selection of the suitable long peripheral catheter in DIVA patients: The significance of ultrasonography.

Background: There are several types of LPC (long peripheral catheters) that vary in length, size, insertion method, and cost. The aim of the study was to evaluate whether ultrasonography can be useful for the selection of the suitable LPC in DIVA (difficult intravenous access) patients.

Methods: Based on the ultrasonographic examination, a long peripheral catheter was selected.

Morphological variation of the deciduous second molars in the Baka Pygmies.

The Baka Pygmies are known for their short stature resulting from a reduced growth rate during infancy. They are peculiar also for their teeth erupt earlier than in any other African population, and their posterior dentition is larger than in non-Pygmy populations. However, the Baka's dental morphology, like several other aspects of their biology, is still understudied.
