Clay-based materials are promising adsorbents for removal of various pollutants from wastewater. This work is aimed to study the changes in structure and adsorption capacity of microwave-treated bentonite after adsorption of lead(II) ions. The structural investigation of the microwave-treated sample reveals that a partial destruction of silica skeleton takes place, and new surface nucleation centers are formed during microwave processing. The adsorption of Pb 2+ on natural bentonite occurs on heterogeneous adsorption sites, whereas the removal of lead on microwave-treated sample is accompanied by the formation of plumbophyllite microcrystals. The natural and microwave-treated adsorbents were tested for lead adsorption in batch experiments. The results were fitted according to Langmuir, Freundlich, Toth, Redlich-Peterson, and Langmuir-Freundlich isotherms of adsorption. The microwave-treated samples revealed substantially higher efficiency towards the removal of lead, their maximal adsorption capacity was 114.7 mg g-1 , whereas natural samples showed only 31 mg g-1 .

Adult mammalian central nervous system axons have intrinsically poor regenerative capacity, so axonal injury has permanent consequences. One approach to enhancing regeneration is to increase the axonal supply of growth molecules and organelles. We achieved this by expressing the adaptor molecule Protrudin which is normally found at low levels in non-regenerative neurons. Elevated Protrudin expression enabled robust central nervous system regeneration both in vitro in primary cortical neurons and in vivo in the injured adult optic nerve. Protrudin overexpression facilitated the accumulation of endoplasmic reticulum, integrins and Rab11 endosomes in the distal axon, whilst removing Protrudin's endoplasmic reticulum localization, kinesin-binding or phosphoinositide-binding properties abrogated the regenerative effects. These results demonstrate that Protrudin promotes regeneration by functioning as a scaffold to link axonal organelles, motors and membranes, establishing 2 important roles for these cellular components in mediating regeneration in the adult central nervous system.

The flotation process of power plants’ ash-slag materials treatment is considered in the article. The original method related to preparing of ash-slag waste before their further bioleaching processing is proposed. The positive results of rare earth metals extraction efficiency increase by bioleaching are obtained. The essence of proposed approach is as follows. Coal combustion’s ash-slag waste is mixed with water to obtain a fine suspension, in which the carbonaceous reagent is injected. Flotation treatment of ash suspension is carried out in mechanical flotation machine with flotation time equal to 15-18 min and air flow rate equal to about 0.7-0.8 m3/(m2·min). The chamber product as treated ash suspension is going to the separation in open hydrocyclone. In such a case the concentration product in the form of ash product is derived to special site, and hydrocyclone overflow is directed to the clearing in pressure flotation machine for extraction of metal ions from the liquid. A positive effect of rare earth metals’ extraction rising related in particular to scandium about 26.6-30.3%, yttrium — 28-34.7%, lanthanum — 50.5-21.5%, as well as precious metals such as gold — 18.7-21.6%, silver — 11.4-21.4% is obtained.

The true picture of the severity and the degree of central nervous system (CNS) in children of the first months of life, doesn´t is always reflected. The outcome of the disease, including unfavorable, is obvious only to the 9-12 months of age due to the features that are assessed as the phenomena of self-defense. A lot of attention in modern Russian and foreign literature is given to the biochemical risk factors for the development of various diseases and their complications, in particular the indicators of oxidative stress, lipid peroxidation, oxidative modification of proteins and antioxidant defense, neurospecific factors involved in the processes of maturation, differentiation and maintain the viability of brain neurons. However, the diagnostic potential of the investigated markers in children didn´t revealed. Purpose of this study is determination of markers of neurological deficits in infants on the basis of neurotrophic factors, indicators of oxidative stress and endothelial dysfunction. Materials and methods. Comprehensive survey of 134 children (61 boys and 73 girls) aged from 0 to 9 months was carried out with the assessment of neurological status and biochemical markers. Results of study. The first component of the nervous tissue of the brain, responding to hypoxia, is microglial environment, which is caused by the growth of lesions S100- protein (i.e., the neuron at the stage of 0-1 months didn´t been metabolic changes - this is evidence of low levels of SOD and MDA).
