Dental Status of Victims from Batajnica’s Mass Graves

The aim of this paper is to present the post mortem dental evidence and dental health of the victims interred during 1999 in five grave pits at Batajnica near Belgrade. The investigated sample comprised 32 individuals with only maxillae preserved, 80 with mandible, and 260 individuals with both jaws. We have found high degree of enamel hypoplasia (25.89%), frequent signs of the severe forms of periodontal disease (18.55%), very high percent of antemortem tooth loss (31.48%), and evidence of edentate jaws in an early age of individuals. Amalgam was predominant material for tooth fillings; implants and non-metal ceramic crowns were not found, and three quaters of edentate individuals were found with full prostetic dentures. Despite the detailed postmortem dental analysis, antemortem dental charts were not collected. These individuals were identified by other forensic methods

Editorial: Antimicrobial nanostructured polymeric materials and nanocomposites, volume II

Antimicrobial resistance (AMR) and infections caused by multidrug-resistant microbial pathogens represent one of the major clinical challenges responsible for high-level morbidity and mortality. They are a significant problem to the public health and the economic stability of societies all over the world. In November 2021 WHO has declared AMR as one of the top 10 global public health threats (Antimicrobial resistance (who.int)). According to CDC’s 2019 AMR Report, although declining since 2013, with 2.8 million new cases and more than 35,000 deaths each year, the number of people facing the AMR problem in United States is still too high (Antibiotic Resistance Threats in the United States, 2019 (cdc.gov)). AMR also remains the major health concern of EU with more than 670,000 new cases of infections caused by antibiotic-resistant bacterial strains and more than 33,000 deaths per year (Antimicrobial resistance surveillance in Europe 2022 - 2020 data (europa.eu)). In 2019 China recorded 39-% drop of antibiotic use in hospitalised patients compare to 2011 (Antimicrobial resistance - China (who.int)). Still, with 73,000 estimated new cases only for multi-drug resistant tuberculosis, the region remained at second position of the global highest incident rates (Antimicrobial resistance - China (who.int)). Each year a large number of people receive different kinds of implants, for example, hip or knee. However recent discoveries reveal that, either during the operative protocol or due to secondary infections, the implant’s surface could be colonized by bacteria, fungi, or both which can have serious consequences on a patient’s health. According to Annual Epidemiological Report of ECDC in 2016, post-surgical infections were identified as most common healthcare-associated infections (Surgical site infections - Annual Epidemiological Report 2016 [2014 data] (europa.eu)). In recent years it has been also recognized that microbial biofilms are ubiquitous, which has resulted in a number of studies from a biofilm perspective. Currently, great efforts are focused on the development of innovative therapeutic strategies regarding both novel drug candidates and drug delivery systems for treating microbial infections associated with implants. However, despite all these efforts as well as the urgent need, an effective and long-lasting solution to this problem is still not found. In the last decades, great attention is paid to nanostructured polymeric materials and nanocomposites because of their unique properties, which make them appropriate candidates for various applications in different medical and pharmaceutical fields. This Research Topic draws attention to the up-to-date findings regarding these issues and advanced therapeutic strategies and approaches as possible solutions

Cases of spontaneous interbreeding of wolf and domestic dog in the region of Southeast Banat

The study presents the first documented data indicating the occurrence of spontaneous interbreeding of wolf and domestic dog in nature on the territory of Serbia, based on three specimens originating from the region of Southeast Banat. Some unique morpho-anatomical malformations of the cranium in two specimens are described. Based on complex morphological and craniometrical analysis of hybrid specimens and comparison with the corresponding material of authentic wolves from this region, it is possible to follow a local process of multiple wolf/dog hybridization and disturbance of the authentic genetic structure of wolf. The identification of wolf/dog hybrids is a subject of primary concern for the development of conservation and management strategies. Because of great vulnerability of the population of South-Carpathian wolves on the boundaries of their range in Serbia, there is a need for permanent and increased protection in order to maintain their adequately strong population in this region.U ovoj studiji po prvi put se prezentuju podaci o spontanom parenju vuka i domaćeg psa u prirodnim uslovima na teritoriji Srbije, zasnovani na tri hibridna primerka jugoistočnog Banata. Na osnovu složene morfološke i kraniološke analize hibrida i poređenjem sa "materijalom autohtonih" vukova iz tog regiona, moguće je pratiti proces lokalne multipne hibridizacije sa psima i poremećaja autentične genetičke strukture vuka. Identifikacija hibrida vuka i psa jeste od naročite važnosti u razviću konzervacije, zaštiti i strategiji menadžmenta.nul

Unapređenje koncepta medicinskih informacionih sistema u cilju smanjenja efekata i posledica epidemija i pandemija

The emergence and fast expansion of huge epidemics and pandemics besides the effect on everyday life of people through the change of health, economic, social and political routine, greatly influence the existing IT products, with a significant emphasis on large information systems which are exploited daily. The main issue which naturally arises is the effective decrease of the rapid spread of epidemics. The reduction of disease transmission is most effectively achieved by socially distancing people and reducing their contacts. In addition to engaging health resources in combating the epidemic, there is also a need for the intensive use of IT solutions that can help slowdown the spread of epidemics, enable continuous monitoring of the affected area, enable rapid and early diagnosis of diseases, reduce contacts between infected and uninfected people, predict trends of the spread of epidemics in order to act in a targeted and proactive manner, etc. This doctoral dissertation presents an improved concept of medical information systems which is aimed at the reduction of effects and consequences of epidemics and pandemics. It enables a better response of the medical information system to the challenges which will be posed by future epidemics and pandemics, not just the COVID- 19 pandemic, which was taken as a case study. The concepts proposed in this doctoral dissertation are applicable to all existing medical information systems both in the Republic of Serbia and in the region. The main objective of the scientific research is to improve the concept of medical information systems in order to reduce the effects and consequences of epidemics and pandemics. The most important objectives of this doctoral dissertation are: the improved concept of medical information system, improved level of collaboration of medical information systems with other information systems outside of the primary health care level, increased level of social distance by implementing new medical information system services, proposed machine learning model for the fast and early diagnosis of COVID -19 disease based on radiological images of lungs, timely and accurate reporting in order to provide conditions for the rapid and adequate response and planning of human and material resources allocation, confirmation of proposed concepts by the practical implementation of certain proposed services and functionalities built into the real medical information system MEDIS.NET which is used daily

The influence of chemical characteristics of precipitation on tree health in Banjica Forest (Belgrade, Serbia)

The most represented tree species in the Banjica Forest are Acer negundo, Quercus robur, Acer pseudoplatanus, Populus nigra, Fraxinus pennsylvanica, Fraxinus ornus and Robinia pseudoacacia. According to the ICP Forests combined assessment (degree of defoliation and decolorization), endangered species are Populus nigra (64.3% of heavily damaged trees), Quercus robur (45.5%), Fraxinus pennsylvanica (37.0%) and Acer negundo (26.6%), while the situation is much better for Acer pseudoplatanus and Fraxinus ornus. For Robinia pseudoacacia, 83% of trees are without decolorization, however, defoliation is established. In the period from April to October 2009, the average pH of rainwater was 5.46, and 5.18 in the period from November 2009 to March 2010. The concentration of SO42- in the period from April to October 2009 amounted to an average of 24.21 mg/l, and 28.87 mg/l in the period from November 2009 to March 2010. The concentration of SO42- and pH values is a possible explanation for the condition of the trees. [Acknowledgments.

Spectrophotometric and uplc study of reaction between [AuCl4] - and quercetin

The equilibrium and kinetics of the reaction between tetrachloroaurate(III) ion (AuCl4 - ) and quercetin in 0.1 M HClO4 were studied spectrophotometrically. The fast and the slow reaction steps were distinguished in the reaction mechanism, depending on the ratio of AuCl4 - and quercetin concentration. The stoichiometry of reaction, determined by molar ratio and Jobb’s methods, was 1:1. The kinetics of complex formation was followed under the pseudo-first order conditions by measuring the absorbance at 294 nm vs. time as the function of quercetin concentration in 5 – 15 fold excess.Physical chemistry 2008 : 9th international conference on fundamental and applied aspects of physical chemistry; Belgrade (Serbia); 24-28 September 200

Theoretical and experimental analysis of dynamic processes of pipe branch for supply water to the Pelton turbine

The paper presents the results of the analysis of pipe branch A6 to feed the Hydropower Plant ”Perućica” with integrated action Pelton turbines. The analysis was conducted experimentally (tensometric) and numerically. The basis of the experimental research is the numerical finite element analysis of pipe branch A6 in pipeline C3. Pipe branch research was conducted in order to set the experiment and to determine extreme stress states. The analysis was used to perform the determination of the stress state of a geometrically complex assembly. This was done in detail as it had never been done before, even in the design phase. The actual states of the body pipe branch were established, along with the possible occurrence of water hammer accompanied by the appearance of hydraulic oscillation. This provides better energetic efficiency of the turbine devices. [Projekat Ministarstva nauke Republike Srbije, br. TR35049 and br. TR 33040

Reintroduction of the European beaver (Castor fiber L.) into Serbia and return of its parasite: The case of Stichorchis subtriquetrus

After becoming extinct in the second half of the 20th century, the European beaver (Castor fiber L., 1758) was successfully reintroduced from Bavaria into Serbia during 2004-2005. In the necropsy of an adult female beaver (found dead in December of 2007), we discovered some parasites identified as Stichorchis subtriquetrus in the colon and peritoneal area. This is the first occurrence of the given specific parasite of beavers in Serbia. Decoding of a subcutaneous implanted microchip has confirmed that our specimen was one of the released beavers. We therefore conclude that the parasite in question was reintroduced into Serbia with the beavers originating from Bavaria.Nakon nestanka u drugoj polovini XX veka, evropski dabar (Castor fiber L. 1758) je tokom 2004-2005. godine, uspešno reintrodukovan sa područja Bavarske u Srbiju. Tokom obdukcije jedne adultne ženke(pronađena mrtva u decembru 2006) pronašli smo parazite u želucu koji su identifikovani kao Stichorchis subtriquetrus. To je prvi nalaz ovog specifičnog parazita dabra u Srbiji. Dekodiranjem subkutano implantiranog mikročipa, potvrđeno je da pronađena ženka jedna od 20 jedinki koje su decembra 2004. godine naseljene na području Specijalnog rezervata prirode Obedska bara. Ova činjenica nam sugeriše da je parazit neželjeno reintrodukovan u Srbiju zajedno sa dabrovima koji su poreklom iz Bavarske naseljavani u Srbiju.Projekat ministarstva br. TR 2001

A survey in natural forest ecosystems of Vietnam reveals high diversity of both new and described Phytophthora taxa including P. ramorum

In 2016 and 2017, surveys of Phytophthora diversity were performed in 25 natural and semi-natural forest stands and 16 rivers in temperate and subtropical montane and tropical lowland regions of Vietnam. Using baiting assays from soil samples and rivers and direct isolations from naturally fallen leaves, 13 described species, five informally designated taxa and 21 previously unknown taxa of Phytophthora were isolated from 58 of the 91 soil samples (63.7%) taken from the rhizosphere of 52 of the 64 woody plant species sampled (81.3%) in 20 forest stands (83.7%), and from all rivers: P. capensis, P. citricola VII, VIII, IX, X and XI, P. sp. botryosa-like 2, P. sp. meadii-like 1 and 2, P. sp. tropicalis-like 2 and P. sp. multivesiculata-like 1 from Phytophthora major phylogenetic Clade 2; P. castaneae and P. heveae from Clade 5; P. chlamydospora, P. gregata, P. sp. bitahaiensis-like and P. sp. sylvatica-like 1, 2 and 3 from Clade 6; P. cinnamomi (Pc), P. parvispora, P. attenuata, P. sp. attenuata-like 1, 2 and 3 and P. ×heterohybrida from Clade 7; P. drechsleri, P. pseudocryptogea, P. ramorum (Pr) and P. sp. kelmania from Clade 8, P. macrochlamydospora, P. sp. ×insolita-like, P. sp. ×kunnunara-like, P. sp. ×virginiana-like s.l. and three new taxa, P. sp. quininea-like, P. sp. ×Grenada 3-like and P. sp. ×Peru 4-like, from Clade 9; and P. sp. gallica-like 1 and 2 from Clade 10. The A1 and A2 mating types of both Pc and Pr co-occurred. The A2 mating type of Pc was associated with severe dieback of montane forests in northern Vietnam. Most other Phytophthora species, including Pr, were not associated with obvious disease symptoms. It is concluded that (1) Vietnam is within the center of origin of most Phytophthora taxa found including Pc and Pr, and (2) Phytophthora clades 2, 5, 6, 7, 8, 9, and 10 are native to Indochina.info:eu-repo/semantics/publishedVersio
