Development of Novel Composite Biocompatible Materials by Surface Modification of Porous Inorganic Compounds Using Bambus[6]Uril.

In this present investigation, a novel series of composite materials based on porous inorganic compounds-hydroxyapatite and diatomite-have been innovatively formulated for the first time through surface modification employing the promising macromolecular compound, bambus[6]uril. The process entailed the application of a bambus[6]uril dispersion in water onto the surfaces of hydroxyapatite and diatomite. Extensive characterization was carried out, involving IR spectroscopy and SEM.

Acute kidney injury in neonatal intensive care: Medicines involved.

Background: The incidence of acute kidney injury (AKI) in neonates in the intensive care units and neonatal intensive care (NICU) according Plotz et al. ranges from 8% to 22% [3]. According to Andreoli, neonatal death due to AKI in NICU amounts up to 10-61% [1].

[Dynamics of the morphofunctional status of digestive organs in patients with chronic gastroduodenitis during monotherapy with sulfate sodium-calcium mineral water].

The authors describe morphofunctional changes in gastroduodenal tract in patients with chronic gastroduodenitis. Some of them have previously undergone laparoscopic cholecystectomy for cholelithiasis. Balneotherapy with mineral water "Uvinskaya" has a good effect in the above disease and therefore is recommended for prevention and treatment of patients with chronic gastroduodenitis as well as for prevention of repeated cholelithiasis after cholecystectomy.

[Clinical and morphological aspects of Helicobacter pylori invasion in reflux esophagitis].

The mucosal biopsies morphological investigation of the lower third of esophagus were conducted for Helicobacter pylori detection in 43 patients with reflux-esophagitis. Helicobacter pylori were detected in 66.7%, gastric metaplasia-in 83.

[Glucose consumption and dehydrogenase activity of the cells of the arsenite-oxidizing bacterium Pseudomonas putida].

The rates of glucose assimilation and dehydrogenase activity were studied in Pseudomonas putida oxidizing arsenite. The rate of glucose utilization by the cells decreased in the presence of arsenites in the medium at the beginning because of the microbial adaptation to arsenite. The activity of dehydrogenase fell down when the cells were cultivated in the medium with arsenite.

[Catalase activity of a Pseudomonas putida strain oxidizing arsenic].

Trivalent arsenic ions added to the medium stimulated the catalase activity of a Pseudomonas putida 18 culture correlating with the rate of arsenic oxidation. As soon as the process of arsenic oxidation stopped, the activity of catalase decreased. Apparently, the production of H2O2, its decomposition by catalase and oxidation of As(III) to As(V) by the formed oxygen are a device for detoxication of trivalent arsenic acquired by the cell in the course of evolution.
