abstract in this study the effects of land use changes from pasturelands to croplands on soil microbiological and biochemical properties were studied in kangaver, dehno and soltanye regions. composite soil samples from 0-20 and 20-40 cm depths of pasture and cultivated lands were taken from kangaver, dehno and soltanye regions, and soil microbial respiration, microbial biomass c and n, and urea...

To gain better knowledge of the effects residual chlorothalonil on soil characteristics and microbial communities, we evaluated dissipation different concentrations respiration, enzyme activities, community structure in yellow–brown loam soils. Bacterial fungal communities were examined using traditional plate counting polymerase chain reaction–denaturing gradient gel electrophoresis (PCR–DGGE)...

Atrazine has been extensively used in China’s agricultural production for a long time and the potential risks to environment have received widespread attention. The purpose of this study was examine effect continuous application atrazine on soil herbicide residues, enzyme activity, microbial community structure, as well provide theoretical reference appropriate improvement soil. Previous studie...

A study was made of the enzyme content of the isolated cell walls and of a plasma-membrane preparation obtained by centrifugation after enzymic digestion of the cell walls of baker's yeast. The isolated cell walls showed no hexokinase, alkaline phosphatase, esterase or NADH oxidase activity. It was concluded that these enzymes exist only in the interior of the cell. Further, only a negligible a...

Background Intestinal ischemia is often caused by a malperfusion of the upper mesenteric artery. Since the intestinal mucosa is one of the most rapidly proliferating organs in human body, this tissue can partly regenerate itself after the onset of ischemia and reperfusion (I/R). Therefore, we investigated whether glycine, sodium pyruvate, and resveratrol can either support or potentially harm r...

We used DNA-based pyrosequencing to characterize the bacterial community structure of the sandy soil of an apple orchard with different manure ratios. Five manure percentages (5%, 10%, 15%, 20% and 25%) were examined. More than 10,000 valid reads were obtained for each replicate. The communities were composed of five dominant groups (Proteobacteria, Actinobacteria, Chloroflexi, Acidobacteria an...

This comparative investigation aimed to evaluate controlling factors for the changes of chemical and microbial properties in soils taken from fertilizer experiments carried out mainly Chernozem Andosol Hungary Japan, respectively. The plant available nutrient content soil, stock C N soil parameters carbon nitrogen cycles were examined under different land-use vegetation. In Japanese soils, ther...

Hypolactasia associated with severe iron-deficiency anemia has been reported in several studies. The objective of the present study was to determine whether hypolactasia is associated with the degree and duration of iron-deficiency anemia. Newly weaned male Wistar rats were divided into a control group receiving a diet supplemented with iron (C) and an experimental group (E) receiving a diet no...
