Epigenetic Modulating Chemicals Significantly Affect the Virulence and Genetic Characteristics of the Bacterial Plant Pathogen pv. .

Epigenetics is the study of heritable alterations in phenotypes that are not caused by changes in DNA sequence. In the present study, we characterized the genetic and phenotypic alterations of the bacterial plant pathogen   pv. () under different treatments with several epigenetic modulating chemicals.

Persistence of pv. in Field Soil in Central Europe.

pv. () is a bacterium that causes black rot of crucifers. The greatest losses of brassica crop production usually result from seed-borne infection, but carry-over of inoculum in field soil may also be possible.

Assessment of Antioxidants in Selected Plant Rootstocks.

The service tree () is a wild fruit tree with immense medicinal and industrial value. This study aimed at determining the four major groups of antioxidants (flavonoids, phenolic acids and aldehydes, catechin and procyanidin) in rootstocks of (genotypes O-LE-14 and O-LE-21), (genotypes O-LE-14 and O-LE-21), (genotype O-LE-9) and (BA 29) (genotypes O-LE-14 and O-LE-21). Hyperoside (Quercetin 3-D-galactoside) was the most abundant flavonoid compound, since its average content in the rootstocks of (O-LE-21) was 180.

[The seroprevalence of HCV among injecting drug users in the years 2004-2008 in Slovakia].

Introduction: Virus of hepatitis C (HCV) is the leading cause of chronic liver disease, including cirrhosis and cancer, and the most common indication for liver transplantation. In industrialised countries, injecting drug use is currently the most important risk factor for infection with hepatitis C, resulting in high prevalence of hepatitis C among injecting drug users (IDUs). The aim of the study was to assess the seroprevalence of HCV infection and distribution of genotypes among IDUs in the years 2004-2008.

[Virological sustained response to former young intravenous drug abusers with chronic hepatitis C treated by pegylated interferon-α plus ribavirin].

Introduction: The most risk group with high rate of infection of viral hepatitis C represents the former drug abusers (IDUs).

Objectives: The objectives of the clinical study were to assess the sustained virological response (SVR) in the group of former IDUs with chronic hepatitis C (CHC) treated with pegylated interferon-α and ribavirin.

Patients And Methods: Of 293 previously untreated (naive) former IDUs with CHC who have started treatment, we assessed 239 (69 women, 170 men) with an average age of 27 years who completed treatment and received a follow-up examination after 24 weeks.
