Use of Ribav and succinate for stimulating natural resistance of chicks at different stages of ontogeny

The aerosol use of Ribav before incubation and succinic acid on the 19th day of incubation of eggs leads to optimizing metabolic processes in embryos, which promotes an increase of viability of chicks both in early and late stages of embryogenesis.     

Variability of spring wheat grain quality in the Middle Volga Region of the Russian Federation under the effect of variety and environment

The effect of technological factors (varieties, fertilizers, and sowing rate) and weather conditions of the Middle Volga Region of the Russian Federation on variability of the quality of soft spring wheat grain is analyzed on the basis of long-term investigations (2003–2008).

Determination of cycle cut off in real-time PCR for the detection of regulated plant pathogens

Given the high importance of an accurate detection for quarantine plant pathogens, and the risk of false positive or false negative results, a detection method must be correctly validated. A statistical procedure has been developed to determine the cycle cut off and the corresponding limit of detection in real-time PCR, considering a risk of false positive results of 1% and a probability of detection of 95%. The procedure presented in this paper is easy to develop and can be applied to any plant pathogen to be detected by real-time PCR.     

EPPO database on diagnostic expertise: http://dc.eppo.org

In 2004, the EPPO Council expressed profound concerns about the decreasing expertise in plant protection and declared a state of emergency for Plant Health (‘Madeira declaration’). As diagnostics is one of the scientific fields which are vital for sustaining sound plant health policies, a questionnaire was launched and all EPPO member countries were asked to provide information about their diagnostic expertise, focusing on regulated pests or pests which may present a risk to the EPPO region. In 2006, results of the questionnaire were analysed and compiled by the EPPO Secretariat into a new database. This database now contains detailed information (contact addresses, quality programmes, and accreditations) for 80 diagnostic laboratories from 28 EPPO member countries. More than 500 experts are now registered with details about their diagnostic expertise (pests diagnosed and methods used). The EPPO database on diagnostic expertise can be freely accessed on the Internet: http://dc.eppo.org .

Anti-Inflammatory Activity of Chitooligosaccharides in Vivo

All the reports to date on the anti-inflammatory activity of chitooligosaccharides (COS) are mostly based on in vitro methods. In this work, the anti-inflammatory activity of two COS mixtures is characterized in vivo (using balb/c mice), following the carrageenan-induced paw edema method. This is a widely accepted animal model of acute inflammation to evaluate the anti-inflammatory effect of drugs. Our data suggest that COS possess anti-inflammatory activity, which is dependent on dose and, at higher doses, also on the molecular weight. A single dose of 500 mg/kg b.w. weight may be suitable to treat acute inflammation cases; however, further studies are needed to ascertain the effect upon longer inflammation periods as well as studies upon the bioavailability of these compounds.
