Electrochemical Behavior of Reduced Graphene Oxide Supported Germanium Oxide, Germanium Nitride, and Germanium Phosphide as Lithium-Ion Battery Anodes Obtained from Highly Soluble Germanium Oxide.

Germanium and germanium-based compounds are widely used in microelectronics, optics, solar cells, and sensors. Recently, germanium and its oxides, nitrides, and phosphides have been studied as active electrode materials in lithium- and sodium-ion battery anodes. Herein, the newly introduced highly soluble germanium oxide (HSGO) was used as a versatile precursor for germanium-based functional materials.

Identification of Barium Hydroxo-Hydroperoxostannate Precursor for Low-Temperature Formation of Perovskite Barium Stannate.

A breakthrough "superoxide colloidal solution route" for low-temperature synthesis of barium and strontium stannate perovskites and their doped analogues was recently introduced. The synthesis starts from hydrogen peroxide-rich stannate solutions and yields a so-called "crystalline superoxide molecular cluster" that is converted by low temperature (<300 °C) to the respective perovskites. In this paper, the so-called "crystalline superoxide molecular cluster" is identified as a superoxide-free, barium trihydroxo(hydroperoxo)peroxostannate, BaSn(OH)(OOH)(OO) phase (BHHPS).

[Search for new regulatory elements of the Bithorax complex in Drosophila melanogaster].

The Ultrabithorax (Ubx), Abdominal-A (Abd-A), and Abdominal-B (Abd-B) homeotic genes of the Bithorax complex are responsible for the development of body segments in Drosophila melanogaster. Their regulatory region of approximately 300 kb harbors a series of specific enhancers, each regulating expression in a single parasegment. Molecular genetic analysis of the Abd-B gene revealed the regulatory modules MCP, Fab-7, and Fab-8, which contain insulators with adjacent silencers.

[L-pyroglutamyl-D-alanine amide normalizes the function of the developing brain damaged by antenatal alcoholization in rats].

The effects of the synthetic dipeptide, L-pyroglutamyl-D-alaninamide (LPDA) were studied in the experiments on offspring of alcoholized during the pregnancy (5 g/kg/day) females. This dipeptide, which revealed the nootropic activity in previous experiments, was injected to the pups in dose of 1 mg/kg from 8 to 19 days of life. LPDA was shown to prevent the delayed disturbances of learning in passive avoidance test, of extrapolatory behaviour in escape test, to attenuate the emotional hyperreactivity.

Active immunization against bioregulators: behavioural and catecholamine changes in albino rats immunized against sydnophen.

Active immunization of white rats against the catecholamine analogue, sydnophen, results in physiological changes extending over two months. The levels of noradrenaline in blood, and dopamine in brain, were depressed, some behavioural activities were reduced and alcohol consumption was lowered. On this basis, active immunization against various bioregulators--a method of inverse regulation--shows promise as a method for achieving long-term adjustment of physiological status.
