Synchrotron single-crystal XRD, IR-, Raman spectroscopy and high pressure study of synthetic krieselite.

Spontaneous crystals of krieselite (Ge analogue of topaz) with the chemical formula Al[(GeSi)O](FOH) were synthesized using a thermo-gradient hydrothermal method at a temperature of 600/650 °C and pressure of 100 MPa. The unit cell parameters are: a = 8.9732(8) Å, b = 8.

Synthetic brunogeierite FeGeO: XRD, Mössbauer and Raman high-pressure study.

We present complex spectroscopic data of the synthetic brunogeierite (Fe)GeO with space group Fd3¯m of spinel structure: a = 8.3783 (6) Å, V = 588.12 (13) Å.

The effect of short-term disturbance of day 3 embryo culture on the development and implantation.

This study is carried out to estimate the effect on embryo development and implantation potential performed by inevitably occurring short-term 3-day embryo culture condition disorders due to light microscopy applied for morphology parameter assay. One thousand two hundred and fifty-three IVF program results were analyzed to measure the pregnancy rate on embryo transfer and the percentage of embryos reached the blastocyst stage. In 58% of cases, on the 3rd day the quality of embryos was not evaluated ( = 730), while in 42% of cases the evaluation was done on day 3 ( = 523).

URGENT COLONOSCOPY IN LOWER INTESTINAL BLEEDING.

Unlabelled: The aim of the study was to compare the diagnostic efficacy and safety of emergency colonoscopy without colon preparation at patients with intestinal bleeding.

Material And Methods: In a comparative cohort study included 252 patients admitted due to intestinal bleeding in 2006- 2015. 118 men, women 134.

Effect of laser optoperforation of the zona pellucida on mouse embryo development in vitro.

The effect of laser optical perforation of the zona pellucida on the viability and development of mouse embryos has been studied. Operations of zona pellucida thinning and single or double perforation were carried out on 2-cell embryo, morula, and blastocyst stages with a laser pulse (wavelength 1.48 µm, pulse duration 2 ms).

Two mechanisms of interferon production by leukocytes from immunized animals.

Leukocytes from animals immunized against measles were treated with different doses of interferon and 5-fluorouracil. Under the influence of virus-inducer, two mechanisms of interferon production were realized in the leukocytes: early after immunization (1 day), pre-existing interferon was released; subsequently (4 days) de novo interferon production was started. Interferons induced in cultures of leukocytes from animals at 1 and 4 days after immunization were shown to differ in some physico-chemical properties.
