Plastic Solid Waste (PSW) in the Context of Life Cycle Assessment (LCA) and Sustainable Management.

Over the past few decades, life cycle assessment (LCA) has been established as a critical tool for the evaluation of the environmental burdens of chemical processes and materials cycles. The increasing amount of plastic solid waste (PSW) in landfills has raised serious concern worldwide for the most effective treatment. Thermochemical post-treatment processes, such as pyrolysis, seem to be the most appropriate method to treat this type of waste in an effective manner.

A review on thermal and catalytic pyrolysis of plastic solid waste (PSW).

Plastic plays an important role in our daily lives due to its versatility, light weight and low production cost. Plastics became essential in many sectors such as construction, medical, engineering applications, automotive, aerospace, etc. In addition, economic growth and development also increased our demand and dependency on plastics which leads to its accumulation in landfills imposing risk on human health, animals and cause environmental pollution problems such as ground water contamination, sanitary related issues, etc.

[Peculiarities of metabolic syndrome and nonalcogolic fatty liver disease in menopausal women].

Correlation between menopause metabolic syndrome and nonalcogolic fatty liver disease (NAFLD) is reviewed. NAFLD refers to a wide spectrum of liver disease ranging from simple fatty liver (steatosis), to nonalcoholic steatohepatitis, to cirrhosis. The causes and pathogenetic factors of the disease are still under investigation.

[Haemodynamic role of blood-plasma circulating cell-free DNA and contained therein high-molecular-weight CpG-rich fraction in pathogenesis of arterial hypertension and atherosclerosis obliterans of carotid arteries].

The hydrodynamic resistance (HR) of blood is one of the components of the total peripheral resistance. High-molecular-weight DNA appears to decrease the HR in accordance with the Toms's effect. The present study was undertaken to investigate the HR and properties of cell-free DNA circulating in the blood plasma (hereinafter referred to as pDNA) of the control donors, patients suffering from either arterial hypertension (AH) alone or that combined with atherosclerotic lesions of the carotid arteries (CAs).

[Pharmacotherapy and prevention of osteoporosis].

In the article data regarding pharmacological prevention of primary osteoporosis is reviewed. Some main aspects of the disease are underlined. The primary prevention of osteoporosis is targeted on building up and sustaining the strength of the skeleton during different periods of human life.
