Bird health and sperm quality in relation to environmental levels of neonicotinoids

2018

Neonicotinoids pesticides are commonly used in agriculture. They are administered mainly prophylactically as seed coating, but can also be sprayed in some cultures. Several characteristics of these molecules make them prone to be transported from the field of application to the surrounding areas. As a consequence, neonicotinoid insecticides represent an environmental risk to non-treated land with potential consequences for non-target species. In this context, we visited 62 farms over the Swiss lowland agricultural area managed under three types of agricultural practices: conventional, integrated production called “IP-Suisse” and organic. We collected soil and vegetation samples in cultivate…

The influence of somatic cell count on sheep milk composition and cheese-making properties

2005

Somatic cell count (SCC) is an important tool for monitoring intramammary infections in dairy cows. However, systematic generalization of this decision rule is not easy in small ruminants. Determination of SCC in sheep milk is important for the processors of milk (indicator of quality), for breeders (mastitis indicator) and could be useful for selection as well. SCC value can be affected by some non-infective factors such as breed, stage of lactation, parity, type of lambing, type of milking, etc. (Bergonier et al., 1994), as well the health status of the udder (Fruganti et al., 1985; Ranucci et al., 1988). In addition, EC Directive 92/46, which regulates the production and commercialisatio…

Der Stoffwechsel verschiedener Carbons�uren durch Milchs�urebakterien

1984

The anaerobic metabolism of citrate, fumarate, gluconate, malate, 2-oxoglutarate and pyruvate by 137 strains of 23 species of lactic acid bacteria was investigated. The bacteria were from various sources (plant material, meat and dairy products, dough and wine) and belonged to the genera Lactobacillus, Leuconostoc, Pediococcus, and Streptococcus. The ability of metabolize the acids was determined by thin layer chromatography or by enzymatic analysis after growth of the strains in a glucose-containing medium. All strains metabolized pyruvate and only 12 mainly heterofermentative strains were malate negative. These strains were also unable to decompose citrate. This acid was fermented by 23 s…

Self-reported consumption of wine and other alcoholic beverages in a German wine area

2013

Petra Fronk,1 Maria Blettner,2 Heinz Decker1 1Institute for Molecular Biophysics, Johannes Gutenberg University of Mainz, Mainz, Germany; 2Institute for Medical Biostatistics, Epidemiology and Informatics, Johannes Gutenberg University of Mainz, Mainz, Germany Purpose: To describe the consumption of alcoholic beverages in a German wine area, with special attention to the number of people drinking more than the tolerable upper alcohol intake level (TUAL). Methods: A cross-sectional study was conducted using a mailed questionnaire, to investigate the weekly consumption of wine, beer, and spirits during the preceding 12 months in Mainz, the state capital of Rhineland-Palatinate, Germany. The a…

Vibrio vulnificus produces quorum sensing signals of the AHL-class

2009

Vibrio vulnificus is an aquatic pathogenic bacterium that can cause vibriosis in humans and fish. The species is subdivided into three biotypes with the fishvirulent strains belonging to biotype 2. The quorum sensing (QS) phenomenon mediated by furanosyl borate diester or autoinducer 2 (AI-2) has been described in human strains of biotype 1, and here we show that the luxS gene which encodes AI-2 is present in all strains of V. vulnificus regardless of origin, biotype or serovar.In this study, we also demonstrate that V. vulnificus produces QS signals of the acylated homoserine lactone (AHL) class (AI-1). AHLs were detected in strains of biotype 1 and 2 from water, fish and human wound infec…

Amylases from orange leaves. Characterization and relation to starch breakdown.

1988

Starch content in adult orange (Citrus sinensis L. Osbeck) leaves was highest at the end of the winter rest period and decreased during flowering and fruit set. Young inflorescence leaves accumulated starch until the June drop period to decrease to a low value at the end of it. Both, α- and ß-amylase activities were found in the leaves and the enzymes separated through Sephadex G100 filtration. By electrophoresis in polyacrylamide gels with 0.25 % amylopectine, α-amylase was resolved in 5 bands, and ß-amylase in 7. Total amylolitic activity in the leaves was determined throughout the annual cycle in both adult and young leaves. Enzyme activities were not correlated with the rate of starch …

Possible involvement of gibberellins on leaf expansion and carbohydrate accumulation in Citrus

1989

During the spring flush of growth both vegetative shoots and inflorescences are formed in Citrus. Some of these inflorescences bear both flowers and leaves (GOLDSCHMIDT and MONSELISE 1972). The leaves from leafy inflorescences are smaller in size (GUARDIOLA et al. 1984) and differ in composition, both organic (SANZ et al. 1987b) and mineral (EMBLETON et al. 1973) as compared to leaves from vegetative sprouts. Some of these differences are related to the competition of nearby developing flowers and fruitlets, but a different type of regulation may also be involved. Early removal of developing reproductive organs had no effect on leaf growth (SANZ et al. 1987a). Further, inflorescence leaves …

Complete Genome Sequence of a New

2017

ABSTRACT A new Firmicutes isolate, strain HV4-6-A5C, was obtained from the hydrolysis stage of a mesophilic and anaerobic two-stage lab-scale leach-bed system for biomethanation of fresh grass. It is assumed that the bacterial isolate contributes to plant biomass degradation. Here, we report a draft annotated genome sequence of this organism.

Objective The aim of this review is to analyze preclinical and clinical studies investigating the anxiety effects of Citrus aurantium or Citrus sinensis essential oils (EOs). Design The bibliographic research was made on the major scientific databases. Analysis included only articles written in English and published on peer-reviewed scientific journals describing preclinical experiments and clinical trials carried out to investigate the antianxiety effects of Citrus aurantium or Citrus sinensis EOs on anxiety disorders. Clinical studies reporting the antianxiety effects of products containing Citrus aurantium or Citrus sinensis EOs in combination with other active substances, including medi…
