Excavation of mass graves with Serbian context: Complexity of the political milieu.

This paper will discuss the complexity of the investigation of mass graves in today's Serbia (part of ex Yugoslavia), belonging primarily to WWII with an exception of one mass grave from WWI, through the prism of historical events behind it. By interpreting historical and political circumstances, we will show why and on what occasions mass graves, as cultural-historical monuments and symbols of the sufferings of Serbs, Jews, Romani, and other nations or ethnic groups, remained outside the focus of expert teams. Also, through examples of explored sites related to WWII (Visnjica, Topola, Kragujevac, Ada Ciganlija), it will be shown the importance of engaging the forensic expert teams to locate sites, identifing victims and interpretation of historical events from their perspective.

Radical Scavenging and Antimicrobial Properties of Polyphenol Rich Waste Wood Extracts.

The main focus of this study is to assess radical scavenging and antimicrobial activities of the 11 wood extracts: oak (Quercus petraea (Matt.) Liebl., Q. robur L., and Q. cerris L.), mulberry (Morus alba L.), myrobalan plum (Prunus cerasifera Ehrh.), black locust (Robinia pseudoacacia L.), and wild cherry (Prunus avium L.). High-performance thin-layer chromatography (HPTLC) provided initial phenolic screening and revealed different chemical patterns among investigated wood extracts. To identify individual compounds with radical scavenging activity DPPH-HPTLC, assay was applied. Gallic acid, ferulic and/or caffeic acids were identified as the compounds with the highest contribution of total radical scavenging activity. Principal component analysis was applied on the data set obtained from HPTLC chromatogram to classify samples based on chemical fingerprints: Quercus spp. formed separate clusters from the other wood samples. The wood extracts were evaluated for their antimicrobial activity against eight representative human and opportunistic pathogens. The lowest minimum inhibitory concentration (MIC) was recorded against Staphylococcus aureus for black locust, cherry and mulberry wood extracts. This work provided simple, low-cost and high-throughput screening of phenolic compounds and assessments of the radical scavenging properties of selected individual metabolites from natural matrix that contributed to scavenge free radicals.

Trepanation in archaic human remains - characteristic features and diagnostic difficulties.

Three trepanned skulls originated from a medieval archeological site at St. Pantelejmon Church, located in Serbia, all showing characteristic depressions and perforations of the vault of the skull from trepanning. Trepanation refers to the process of creating a defect in the skull by drilling, cutting or scraping and is one of the oldest known surgical procedures. Anthropological assessment of possible cases of trepanation in archaic material is complicated by a differential diagnosis that includes both congenital/developmental lesions such as parietal fenestrae, and acquired conditions such as trauma, infection and malignancy.
