The Neolithic Demographic Transition in the Central Balkans: population dynamics reconstruction based on new radiocarbon evidence.

In this paper, we test the hypothesis of the Neolithic Demographic Transition in the Central Balkan Early Neolithic (6250-5300 BC) by applying the method of summed calibrated probability distributions to the set of more than 200 new radiocarbon dates from Serbia. The results suggest that there was an increase in population size after the first farmers arrived to the study area around 6250 BC. This increase lasted for approximately 250 years and was followed by a decrease in the population size proxy after 6000 BC, reaching its minimum around 5800 BC.

Bone spoons for prehistoric babies: Detection of human teeth marks on the Neolithic artefacts from the site Grad-Starčevo (Serbia).

Around 8000 years ago, throughout the Neolithic world a new type of artefact appeared, small spoons masterly made from cattle bone, usually interpreted as tools, due to their intensive traces of use. Contrary to those interpretations, the small dimensions of spoons and presence of intensive traces of use led us to the assumption that they were used for feeding babies. In order to test that assumption we compared 2230 marks on three spoons from the Neolithic site of Grad-Starčevo in Serbia (5800-5450 cal BC) with 3151 primary teeth marks produced experimentally.

Prognostic Significance of Atrial Fibrillation in Lower Limb Amputee Patients.

Objective: In patients with risk factors or established atherothrombosis, atrial fibrillation (AF) is associated with a poor prognosis compared with patients without AF. The aim of this study was to evaluate the prevalence of AF in patients with lower limb amputation (LLA) and its association with cardiovascular death and adverse cardiovascular events in long-term follow-up.

Methods: Observational prospective study of consecutive patients after index major (transfemoral and transtibial) LLA.

Demography of the Early Neolithic Population in Central Balkans: Population Dynamics Reconstruction Using Summed Radiocarbon Probability Distributions.

The Central Balkans region is of great importance for understanding the spread of the Neolithic in Europe but the Early Neolithic population dynamics of the region is unknown. In this study we apply the method of summed calibrated probability distributions to a set of published radiocarbon dates from the Republic of Serbia in order to reconstruct population dynamics in the Early Neolithic in this part of the Central Balkans. The results indicate that there was a significant population growth after ~6200 calBC, when the Neolithic was introduced into the region, followed by a bust at the end of the Early Neolithic phase (~5400 calBC).

Walking quality after surgical treatment of developmental dysplasia of the hip in children.

We assessed the quality of life of children with developmental dysplasia of the hip (DDH) treated surgically, through analysis of leg length discrepancy, quality of walking and presence of pain in 39 children with DDH between 1991 and 2011 at the University Children's Hospital in Belgrade. Salter's innominate osteotomy combined with derotation and femoral bone shortening was performed. Patients were divided into 3 groups based on their age at operation: the first group included participants operated at age up to 24 months, the second group between 24 and 48 months and the third group above 48 months of life.

[Comparative analysis of gynaecological status of workers from textile and metal industry].

Introduction: Female workers in textile and metal industry are exposed to various physical and chemical hazards that can lead to the occurrence of gynaecological diseases.

Objective: The aim of this study was to estimate the frequency of gynaecological diseases among workers of textile and metal industries.

Method: The investigation comprised 197 female workers, 148 from textile and 49 from metal industry, aged from 26 to 57 years.

[Morbidity patterns of workers employed in pharmaceutical-chemical industry].

Introduction: Work in pharmaceutical-chemical industry is characterized by exposure to numerous hazards, both physical (microclimate, illumination, noise) and chemical (organic solvents). Organic solvents can cause damage to many organic systems and have carcinogenic, teratogenic and mutagenic effects.

Objective: The aim of this study was to analyze patterns of chronic morbidity of workers employed in pharmaceutical-chemical industry during 2002.

Speciations of trace metals in the Danube alluvial sediments within an oil refinery.

A sequential extraction procedure was applied to identify forms of Ni, Zn, Pb and Cu with Fe- and Mn-oxides associated in alluvial sediments of the River Danube within Pancevo Oil Refinery (Serbia). The five steps of the sequential extraction procedure partitioned metals into: CH(3)COONH(4) extractable (S1); NH(2)OH.HCl carbonate extractable and easily reducible (S2); (NH(4))(2)C(2)O(2)/H(2)C(2)O(2) moderately reducible (S3); H(2)O(2)-HNO(3) organic extractable (S4); and HCl acid soluble residue (S5).

Ganglioside GM1 and GM3 in early human brain development: an immunocytochemical study.

The distribution of GM1 and GM3 gangliosides in human brain development between gestational week (g.w.) 6 and 15 was demonstrated by an immunocytochemical approach using polyclonal anti-GM1 and anti-GM3 antibodies.
