Pollution Removal

The objectives of this study are to testing the impacts of Atrush forests on the environment and oxygen production based on I-Tree program, function and management decisions that will improve human health and environmental quality. Human communities derive many essential benefits from natural ecosystems; these benefits represent important and familiar parts of the economy. What has been less appreciated up to this day is that natural ecosystems also perform fundamental life-support services without them human civilizations would cease to thrive. Evaluation of the vegetation structure, conducted during 2017. Data from 21 fields located were analyzed using the I-Tree Eco program. The most common species of trees are Pinus brutia (Turkish pine). Quercus aegilops (Ajo mountain scrub oak ), Plantanus orientalis (Oriental plane tree), Pistacia atlantica (Mt.atlas mastic tree) as well as shrubs Crataegus azarolus (Mediterranean Medlar), Junipours occidentalis (Western juniper), Prunus amygdalus (Almendro), Rhus coriaria (sumac spp), Nerium oleander (Oleander). Results show that the Pollution removal is ( 0.106 ton/year) referred ($280 /year) for sum of surveyed trees and shrubs in Atrush location, and oxygen production is (2 ton/year) .That means there are a effected role of trees on ecosystem in selected area.

The aim of the article was to defi ne the role of the radioactive environment contamination in the formation of ecosystem services strategy. Methods. Monographic, systemic and structural, factor analysis, abstract and logical research methods have been used. The data from the State Statistics Service of Ukraine, the Ministry of Agrarian Policy and Food of Ukraine, the Ministry of Ecology and Natural Resources of Ukraine, materials of scientifi c researches, international materials and reports and other literary sources on the issues investigated have been used as an information base. Results. Retrospective analysis of sources and state of radioactive eco- systems contamination was conducted and the priority steps in developing the concept of ecosystem services in conditions of radiation contamination were found. Conclusions. The current socio-ecological paradigm of the transition from environmental use to environmental management should be refl ected in the relevant envi- ronmental management mechanisms. Currently, when assessing the state of ecosystem services in Ukraine and worldwide one must take into account the changes in food demand of residents of radioactively contaminated areas, the exploitation of radioactively safe ecosystems growth, their overload and degradation. All of this re- quires an inventory of ecosystem services by type, region, consumers, etc. and the formation of a state register of ecosystem services with a clear assignment of area of responsibility for appropriate natural ecosystems. This will help to make the economic evaluation of different ecosystem services and mechanisms of charges for ecosystem services.

In natural ecosystems, plants are constantly exposed to changes in their surroundings as they grow, caused by a lifestyle that requires them to live where their seeds fall. Thus, plants strive to adapt and respond to changes in their exposed environment that change every moment. Heat stress that naturally occurs when plants grow in the summer or a tropical area adversely affects plants’ growth and poses a risk to plant development. When plants are subjected to heat stress, they recognize heat stress and respond using highly complex intracellular signaling systems such as reactive oxygen species (ROS). ROS was previously considered a byproduct that impairs plant growth. However, in recent studies, ROS gained attention for its function as a signaling molecule when plants respond to environmental stresses such as heat stress. In particular, ROS, produced in response to heat stress in various plant cell compartments such as mitochondria and chloroplasts, plays a crucial role as a signaling molecule that promotes plant growth and triggers subsequent downstream reactions. Therefore, this review aims to address the latest research trends and understandings, focusing on the function and role of ROS in responding and adapting plants to heat stress.

Thrombocytopenic Purpura

We describe the case of a peripartum thrombotic thrombocytopenic purpura with fulminant cardiogenic shock treated with extracorporeal life support. Thrombotic thrombocytopenic purpura should be considered in the case of thrombotic microangiopathy with several or severe organ involvement and needs emergent treatment with plasmapheresis (with or without rituximab). In the case of cardiac involvement, aggressive treatment should be considered given the high mortality and the potential complete recovery.

Elucidating the mechanisms of abiotic stress tolerance in different species will help to develop more resistant plant varieties, contributing to improve agricultural production in a climate change scenario. Basic responses to salt stress, dependent on osmolyte accumulation and activation of antioxidant systems, have been studied in Nerium oleander, a xerophytic species widely used as ornamental. Salt strongly inhibited growth, but the plants survived one-month treatments with quite high NaCl concentrations, up to 800 mM, indicating the the species is relatively resistant to salt stress, in addition to drought. Levels of proline, glycine betaine and soluble sugars increased only slightly in the presence of salt; however, soluble sugar absolute contents were much higher than those of the other osmolytes, suggesting a functional role of these compounds in osmotic adjustment, and the presence of constitutive mechanisms of response to salt stress. High salinity generated oxidative stress in the plants, as shown by the increase of malondialdehyde levels. Antioxidant systems, enzymatic and non-enzymatic, are generally activated in response to salt stress; in oleander, they do not seem to include total phenolics or flavonoids, antioxidant compounds which did not accumulate significantly in salt-trated plants

The paper is devoted to a concept study and empirical verification of the hypothesis about existence and development of new post-urban lifestyles in Russian society, which are formed on the basis of industrial and urban state of life, but trying to overcome the urbanism limitations. The authors differentiate posturban representatives as down-shifters and up-shifters. Materials of conducted empirical investigation have demonstrated that innovative technological solutions and modern autonomous eco-friendly housing lifesupport technologies take an important place in post-urban representatives’ socio-economic activity models.
