The effect of salinity on the growth and survival of different localand imported strains of Rhizobium meliloti in liquid media for 72 h was studied in the laboratory. The rhizobial strains were tested for their symbiotic efficiencies with lucerne grown in salinized sand culture and in natural Saudi Arabian soils of dfferent salinities in thegreenhouse. Results have shown that growth of all rhizobial strains investigated in liquid media was adversely affected by high salinity with relatively slight salt tolerance in the local rhizobial strains.Salinization of sand culture to high concentration (100--250 mM NaCl) greatly affected nodulation and symbiotic N2-fixation oflucerne plants grown in it. Growing lucerne in sand of high salt concentration (250 mM NaCl) completely prevented the formation of nodules. Inoculation of lucerne plants grown in sand culture with local isolates of R. meliloti has shown slight salt tolerance up to 100 mM NaCl. These local isolates gave relatively higher symbiotic N2-fixation than the rest of the inoculated rhizobial strains. High salinity of natural soils (9.1 and 14.1 dS m-1) deleteriously affected the nodule formation and the symbiotic N2 fixation in lucerne plants inoculated with all rhizobial strains. Inoculation of lucerne plants with rhizobial strains showing tolerance to salinity in sand culture did not show the same tolerance in natural saline soils, and this could be attributed to the competitive potentiality of the strain used in the soil.

Listeria monocytogenes is a Gram positive, facultative intracellular pathogen with the capacity to cause food poisoning outbreaks as well as severe illness in vulnerable human population groups. In this paper the faecal carriage rate of Listeria monocytogenes in domestic dogs in Isfahan city, determined from 92 faecal samples by bacteriological methods. Listeria monocytogenes was isolated from only one of the samples examined (1.08%). The serotype of isolated bacteria was 1/2b. It was concluded that stray dogs could be a reservoir of the organism as well as a source of human listeriosis in Iran. This is the first report on the isolation of Listeria monocytogenes from domestic dogs in Isfahan city. [ABSTRACT FROM AUTHOR]

There is no data on the effect of maximum and minimum doses of furosemide on heart's work performance and amount of fractional shortening (FS) in echocardiography of rabbit. This study was designed to validate probability of the mentionable effect. Twenty-four healthy female New Zealand white rabbits were divided into four equal groups. Maximum and minimum doses of furosemide were used for the first and second groups and the injection solution for the third and fourth groups was sodium chloride 0.9% which had the same calculated volumes of furosemide for the first two groups, respectively. The left ventricle FS in statutory times (0, 2, 5, 15, 30 minutes) was determined by echocardiography. Measurements of Mean±SD, maximum and minimum amounts for FS values in all groups before injection and in statutory times were calculated. Statistical analysis revealed non-significant correlation between the means of FS. The results of this study showed that furosemide can be used as a diuretic agent for preparing a window approach in abdominal ultrasonography examination with no harmful effect on cardiac function.

Purpose: This study investigates the impact of perceived inclusion among healthcare employees on intrinsic motivation and its subsequent effects on work engagement and stress levels. Drawing from multiple theoretical frameworks, the study hypothesizes the following: (a) perceived inclusion positively influences employees' intrinsic motivation, and (b) perceived inclusion and intrinsic motivation serve as resources that enhance employee well-being by promoting work engagement and reducing stress., Design/methodology/approach: Data were collected from 407 healthcare workers across the European Union. The research objectives were achieved through statistical analysis of the gathered responses., Findings: The results indicate a positive relationship between perceived inclusion and intrinsic motivation. Importantly, both perceived inclusion and intrinsic motivation emerged as significant predictors of work engagement. Additionally, perceived inclusion was found to have a negative association with stress levels, underscoring its importance in healthcare management., Research Limitations/implications: The study is subject to certain limitations, including the cross-sectional design and reliance on self-reported data, which may affect the generalizability of the findings., Practical Implications: The findings highlight the importance of fostering perceived inclusion and intrinsic motivation among healthcare employees to enhance work engagement and reduce stress, thus offering valuable insights for healthcare management practices., Originality/value: This study contributes to the existing literature by examining the complex interplay between perceived inclusion, intrinsic motivation, work engagement and stress within the healthcare sector. It also identifies avenues for future research in this area., (© Emerald Publishing Limited.)
