Recent Advances on Membranes for Water Purification Based on Carbon Nanomaterials.

Every year the problem of water purification becomes more relevant. This is due to the continuous increase in the level of pollution of natural water sources, an increase in the population, and sharp climatic changes. The growth in demand for affordable and clean water is not always comparable to the supply that exists in the water treatment market.

Highly Porous Expanded Graphite: Thermal Shock vs. Programmable Heating.

Highly porous expanded graphite was synthesized by the programmable heating technique using heating with a constant rate (20 °C/min) from room temperature to 400-700 °C. The samples obtained were analyzed by scanning electron microscopy, energy-dispersive spectroscopy, low-temperature nitrogen adsorption, X-ray photoelectron spectroscopy, Raman spectroscopy, thermogravimetry, and differential scanning calorimetry. A comparison between programmable heating and thermal shock as methods of producing expanded graphite showed efficiency of the first one at a temperature 400 °C, and the surface area reached 699 and 184 m/g, respectively.

[The influence of electrical stimulation on the peripheral immune system under the experimental and clinical conditions].

The authors for the first time provide the scientifically-grounded substantiation for the application of electrical stimulation with bipolar pulsed currents for the combined treatment of the patents presenting with acne vulgaris. Experiments on the rabbits have demonstrated the influence of bipolar pulsed currents on the cellular composition of lymph nodes and thereby facilitated the better understanding of certain theoretical aspects of the application of electrical stimulation at large. The clinical study on the application of multi-channel electrical stimulation and microcurrent therapy showed that these physical factors may cause remodeling of immunogenesis in the patents presenting with acne vulgaris manifested as the normalization of the cellular composition of peripheral blood (leukocyte, lymphocyte, T- and B-lymphocyte counts and immunoglobulin levels).

[Peculiarities of behavior of offspring of rats-ambidexters after surviving vital stress].

Psychogenic trauma inflicted to mothers (Wistar rats) during pregnancy is more tragic for establishment of psychoemotional functions in offspring than in the rat pups whose mothers survived prior to pregnancy the stress connected with threat of life. The "antenatal stress" causes in the one-month-old offspring the depression-like behavior, while the stress one month prior to conception--the increased anxiety. Disturbances of the integral behavior in the test "open field" can be caused both by the acute psychogenic trauma of mothers and by its delayed consequences.

[The application of electrical stimulation by bipolar pulsed currents and galanthamine electrophoresis for the rehabilitation of patients with diabetes mellitus].

Clinical observations provided evidence of the positive effects of multichannel electrical stimulation by bipolar pulsed currents in combination with galanthamine electrophoresis applied for the treatment of patients with complicated diabetes mellitus. Such treatment facilitated normalization of water and carbohydrate metabolism and reduction of the body weight; moreover, it improved blood circulation and the state of the nervous system.
