Connections between the Levant and the Balkans in the late Middle Pleistocene: Archaeological findings from Velika and Mala Balanica Caves (Serbia).

Major changes in the technological, economic, and social behavior of Middle Pleistocene hominins occurred at the onset of the Middle Paleolithic, 400-200 ka. However, until recently it was not possible to establish when, where, and how certain forms of Middle Paleolithic behavior appeared and spread into Southeastern Europe, mainly owing to gaps in the Paleolithic record. Here we report new results of dating, material culture, and the archaeological context of finds from the Balanica Cave Complex in Sićevo (Serbia).

High-Resolution AMS Dating of Architecture, Boulder Artworks and the Transition to Farming at Lepenski Vir.

The archaeological site of Lepenski Vir is widely known after its remarkable stone art sculptures that represent a unique and unprecedented case of Holocene hunter-gatherer creativity. These artworks were found largely associated with equally unique trapezoidal limestone building floors around their centrally located rectangular stone-lined hearths. A debate has raged since the discovery of the site about the chronological place of various discovered features.

Factors affecting the patency of arteriovenous fistulas for hemodialysis: Single center experience.

Introduction: Arteriovenous fistulas (AVFs) are the preferred form vascular access for hemodialysis (HD), as they have a low rate of complications and durable function. The aim of our investigation was to analyze the factors that might influence the function of AVFs.

Methods: Data were taken from the computerized patient record system in the Clinic of Urology and Nephrology, Clinical Center, Kragujevac, Serbia, for a 2-year period.

The use of hyaluronic and aminocaproic acid in the treatment of alveolar osteitis.

Background/aim: Alveolar osteitis (AO), also known as “dry socket”, is relatively common post-extraction complication. It probably occurs due to excessive fibrinolytic activity in the coagulum and is characterized by intense pain sensations. The aim of this clinical study was to examine the role of hyaluronic acid and aminocaproic acid in the treatment of AO.

Comparative radiographic and resonance frequency analyses of the peri-implant tissue after dental implants placement using flap and flapless techniques: an experimental study on domestic pigs.

Background/aim: Flapless implant surgery has become very important issue during recent years, mostly thanks to computerization of dentistry and software planning of dental implants placements. The aim of this study was to compare flap and flapless surgical techniques for implant placement through radiographic and radiofrequency analyses.

Methods: The experiment was made in five domestic pigs.
