Enhancement of Polyacrylate Antiscalant Activity during Gypsum Deposit Formation with the Pretreatment of Aqueous Solutions with Spruce Wood Shavings.

Considerable efforts are made worldwide to reduce inorganic scale in reverse osmosis plants, boilers and heat exchangers, evaporators, industrial water systems, geothermal power plants and oilfield applications. These include the development of new environmentally friendly antiscalants and the improvement of conventional ones. The present report is dedicated to the unconventional application of spruce wood shavings in combination with polyacrylate (PAA-F1) in a model case of gypsum scale formation.

Formation of metabolic syndrome as a risk factor of circulatory diseases in drivers.

The authors considered systemic approaches to disclosing factors that promote metabolic syndrome formation and associated risk of ciculatory system diseases in drivers. Examination covered drivers with metabolic syndrome and without it. Findings are that metabolic disorders developing in drivers are occupationally conditioned.

[Neuromyelitis optica and aquaporin-associated syndromes].

Identification of aquaporin-4 antibodies in neuromyelitis optica (NMO) is highly important to provide early diagnosis for starting pathogenetic treatment, and for differential diagnosis in neuromyelitis optica spectrum disorders (NMO-SD). In this paper, we review current pathogenetic and clinical aspects of NMO and NMO NMO-SD. We present our data on the identification of aquaporin-4 antibodies in CNS disorders.

[The role of biofilms in pathogenesis of chronic bacterial rhinosinusitis].

The objective of the present work was to study the contribution of biofilms to the development of chronic bacterial rhinosinusitis. A total of 50 patients with this pathology were available for the examination. Mucosal swabs were taken from the middle nasal passages of all the patients to be used for the detection of biofilms by luminescence microscopy.

[Effect of oregano essential oil on the engraftment and development of Lewis carcinoma in F1 DBA C57 black hybrid mice].

The effect of a low uptake dose of oregano essential oil with drinking water for three months (Origanum vulgare L.) on the degree of Lewis carcinoma engraftment and some parameters of oxidative stress has been studied in vivo using F1 DBA C57 Black hybrid mice. Oregano essential oil has been established to possess an anticancer activity.
