Highly Active Visible Light-Promoted Ir/-CN Photocatalysts for the Water Oxidation Reaction Prepared from a Halogen-Free Iridium Precursor.

A combination of the exceptional stability of -[Ir(HO)(NO)] together with thermolability of nitro and aqua ligands and high solubility in various solvents makes it promising as a brand-new chlorine-free precursor of iridium for the preparation of heterogeneous catalysts. In the current work, a new technique of -[Ir(HO)(NO)] preparation based on hydrothermal treatment of (NH)[Ir(NO)] was developed. For this purpose, the influence of reaction parameters such as the reaction time, temperature, and pH of the solution on the process of hexanitroiridate salt hydrolysis was investigated.

[Cervical myelopathy in the hyperkinetic form of cerebral palsy: combination of botulinum therapy with surgical treatment].

The article describes the case of cervical myelopathy with tetraparesis and sphincter disorders, as a complication of cervical dystonia in a patient with hyperkinetic form of cerebral palsy. Left-side laterocollis in combination with the same side laterocaput was noted. Myelopathy symptoms progressed gradually over one year.

[Specific regular features of trace formation depending on the properties of the trace-receptive surface and the height of blood droplet fall].

The objective of the present work was to study the morphological characteristics of blood stains resulting from the static fall of blood droplets onto a sloping stain-receptive surface depending on its properties and the height of fall. The blood droplets were allowed to fall down from a specially designed device onto the sloping surfaces at an angle of 45 degrees from the height varying from 5 to 200 cm. The receptive surfaces had different absorbing capacity (non-absorbing, moderately absorbing, and well-absorbing surfaces).

[Changes in the heart of neonatal rats after cryptosporidial gastroenteritis of different degrees of severity].

Disturbances at the childhood age increase risk of the appearance of cardiovascular diseases decades later. The nature of this interconnection called ontogenetic programming is not completely understood. Valuable sources of knowledge about mechanisms of ontogenetic programming are data of interspecies study of biology of the body life cycles and of heart physiological capabilities.

[Threshold rat neonatal cardiomyocyte response to gradual cryptosporidial infection severity increase].

Infectious gastroenteritis is one of the common causes of tachyarrythmia, malabsorbtion and growth retardation in children. Our recent studies have indicated that neonatal.cryptosporidial gastroenteritis is associated with long-term cardiomyocyte abnormalities.
