Senescence- and drought-related changes in peroxidase and superoxide dismutase isoforms in leaves of Ramonda serbica
No full textEffect of atmospheric ageing on volatility and ROS of biodiesel exhaust nano-particles
No full textGenerally, the magnitude of pollutant emissions from diesel engines is ultimately coupled to the structure of fuel molecules. The presence of oxygen, level of unsaturation and the carbon chain length of respective molecules influence the combustion chemistry. It is speculated that increased oxygen content in the fuel may lead to the increased oxidative potential (Stevanovic, S. 2013). Also, upon the exposure to UV and ozone in the atmosphere, the chemical composition of the exhaust is changed. The presence of an oxidant and UV is triggering the cascade of photochemical reactions as well as the partitioning of semi-volatile compounds between the gas and particle phase. To gain an insight into the relationship between the molecular structures of the esters, their volatile organic content and the potential toxicity of diesel exhaust particulate matter, measurements were conducted on a modern common rail diesel engine. This research also investigates the contribution of atmospheric conditions on the transfer of semi-volatile fraction of diesel exhaust from the gas phase to the particle phase and the extent to which semi-volatile compounds (SVOCs) are related to the oxidative potential, expressed through the concentration of reactive oxygen species (ROS) (Stevanovic, S. 2013)..
Open questions on the implementation of engineering geology techniques and methods in karst
No full textThe article deals with some questions remained open as concerns the
implementation of techniques and methods of engineering geology to the karst
environment. Karst, a fragile environment characterized by significant peculiarities, must
be carefully studied and analyzed before applying approaches which, even though valid
in other settings, might potentially produce severe problems to the karst landscape and
the natural resources therein contained, including the high-quality karst groundwater
Hierarchical structuring of psychopathological dimensions in youth : current progress and future steps with the Hierarchical Taxonomy of Psychopathology (HiTOP)
No full textOver the past two decades, it has become clear that psychopathology exists on continuous spectra organized hierarchically from broad, general symptom dimensions to more specific ones. This structure is best represented by the Hierarchical Taxonomy of Psychopathology (HiTOP) framework that incorporates individual signs, symptoms, and behaviors at its most specific level while encompassing higher-order dimensions at its broadest level. This commentary gives an overview of studies that evaluated higher-order dimensions of psychopathology and their alignment with the HiTOP framework. Studies consistently support the alignment of youth psychopathology with the HiTOP framework, particularly its general dimension of psychopathology and the broad internalizing and externalizing spectrum. The model also identifies distinct, lower-level dimensions such as fear, affectivity, antagonism, and attention problems. This hierarchical structure is evident across the entire age span but with specific makeup of dimensions appearing to differ between children and adolescents. Rapidly gaining momentum, current evidence indicates HiTOP’s effectiveness in conceptualizing youth mental health. Future studies should focus on exploring the HiTOP structure across different ages and populations, testing its real-world generalizability, selecting the most appropriate assessment tools, and understanding how the framework applies to youth from diverse societies and cultures.

Development of polyphenols-enriched maple sugars by freeze- and vacuum drum drying technologies
No full text[EN] Hot water extract of sugar and red maple bark was added to maple syrup and dried by freeze (FD) and vacuum drum drying (VD) techniques. Addition of maple bark extracts to syrup helped to develop polyphenols-enriched maple sugar. X-ray diffraction revealed that sugar obtained from FD was amorphous in nature, while crystalline when dried by VD. Furthermore, the observation of maple sugar samples under scanning electron microscopy showed smooth and porous surface for FD sugar, while rough and grainy surface for VD sugar. Hausner ratio indicated that sugar produced by VD showed better flow characteristics than FD sugar.Bhatta, S.; Stevanovic, T.; Ratti, C. (2018).

NMR probing of in silico identification of anti-HPV16 E7 mAb linear peptide epitope
No full textA proteomics-based approach was exploited to individuate peptide sequences having the immunogenic potential to evoke humoral response. The epitope search utilized two parameters: the similarity level of the peptide sequence to the host's proteins, and the peptide capability to bind to the major histocompatibility complex class II mols. By this approach, the human papillomavirus 16 E749-63 RAHYNIVTFCCKCDS peptide was individuated as the immunogenic epitope recognized by an anti-HPV16 E7 monoclonal antibody raised against the full-length viral oncoprotein. In this report, two-dimensional NMR spectroscopic expts. unequivocally probe the HPV16 E7 epitope individuation
