Abstract 5426: Down-regulation of cancer metabolism enhances radiosensitivity by impairing the heat shock response

Abstract Therapy (radiation) resistance can, inter alia, be caused by an increased lactate dehydrogenase (LDH) activity, elevated concentrations of the oncometabolite lactate and an overexpression of anti-apoptotic heat shock proteins (HSPs). In this study we aimed to break radioresistance by targeting the cancer metabolism. We could show, for the first time, that the lactate metabolism and heat shock response are co-regulated in two cancer cell systems (murine B16F10 melanoma cells,...

Estimation of motorcycle movement speed, by traffic participants, depending on the (not) use of daytime lights

Previous research in the world, as well as in the Republic of Serbia, was aimed at researching the impact of (not) using daytime running lights, in passenger vehicles, on traffic safety. Research on the impact of the (non) use of daytime running lights by motorcycles on traffic safety has been scarce. Bearing the above in mind, as well as the fact that the occurrence of traffic accidents is influenced by many factors, the authors of this paper decided to conduct an experimental study on a driving...

Sequentiality of beetle communities in the longitudinal gradient of a lowland river in the context of the river continuum concept

The main goal of the study was to recognize the mechanisms underlying assemblage structuring of aquatic beetle fauna inhabiting a medium-sized, lowland river exposed to anthropogenic pressures. An attempt was made to identify the impact of numerous abiotic factors on how beetle communities are formed, with particular emphasis on geomorphological and landscape-related factors, which tend to be omitted from many studies of aquatic organisms. Our intention was to refer the results of our study to the...

Clinical and microbiological effects of photodynamic therapy applied in non-surgical treatment of periodontitis

Background/Aim. Treatment of periodontitis undergoes several treatment phases. Non-surgical periodontal treatment (NSPT) represents the basic treatment stage, and it is applied to all the patients undergoing periodontal treatment. Adjunctive antimicrobial photodynamic therapy (aPDT) is one of several contemporary and relatively new possibilities with a role to inactivate microorganisms responsible for the occurrence and progression of the disease. The aim of this study was to comparatively analyze...

Female infertility in the era of obesity: The clash of two pandemics or inevitable consequence?

AbstractObesity is an epidemic that has led to a rise in the incidence of many comorbidities: among others, reduced fertility is often under‐evaluated in clinical practice. The mechanisms underlying the link between reduced fertility and obesity are numerous, with insulin resistance, hyperglycaemia and the frequent coexistence of polycystic ovary syndrome being the most acknowledged. However, several other factors concur, such as gut microbiome alterations, low‐grade chronic inflammation and oxidative...

DNA barcoding of Chironomidae from the Lake Skadar region: Reference library and a comparative analysis of the European fauna

AbstractAimsThe main aim of this study was to fill a gap in barcoding data of the European Chironomidae of the Balkan region, developing and testing the efficiency of a reference DNA barcode library for ancient Lake Skadar basin species (Montenegro/Albania), a region of Europe never before subjected to barcoding studies on Chironomidae. Another aim was to test the efficiency of DNA barcoding for the identification of European Chironomidae, including the estimation of optimal identification thresholds,...

A Novel Integrated Model under Fuzzy Environments as Support for Determining the Behavior of Pedestrians at Unsignalized Pedestrian Crossings

Pedestrians as a vulnerable category of traffic participants demand a special attention, particularly regarding their behavior at unsignalized pedestrian crossings. Unquestionably, when crossing a road at these types of pedestrian crossings, there is a potential risk, for both the pedestrians and other traffic participants, as well. Accordingly, this article shows the research on pedestrians’ behavior at unsignalized intersections, conducted at four locations in the urban environment of Novi Sad....

The occurrence of the jellyfish Aequorea cf. forskalea in the Adriatic Sea

Jellyfish are becoming an increasingly important component of studies of the global marine environment, as their frequent mass phenomena affect ecosystem performance and have economic and health consequences. Recent research has focused primarily on mass occurrences of scyphozoans and ctenophores, while less attention has been paid to hydromedusae blooms, which can also have significant impacts on the marine ecosystem with economic consequences. Like many members of the Scyphozoa and Ctenophora,...

Thermo-mechanical analysis of linear welding stage in friction stir welding: Influence of welding parameters

The influence of friction stir welding parameters on thermo-mechanical behavior of the material during welding is analyzed. An aluminum alloy is considered (Al 2024 T351), and different rotating and welding speeds are applied. The finite element model consists of the working plate (Al alloy), backing plate and welding tool. The influence of the welding conditions on material behavior is taken into account the application of the Johnson-Cook material model. The rotation speed of the tool affects...
