BACKGROUND Elderly social isolation could be prevented by facilitating communication or mutual helping at the neighborhood level. The helping of elderly neighbors by local volunteers may relate to their community commitment (CC), but ways to measure CC have not been identified. The aim of the present study was to develop a Community Commitment Scale (CCS) to measure psychological sense of belon...

background and objective: photobacterium damselae subsp. damselae is a marine pathogenic bacterium which causes disease in marine animals and human. this bacterium mostly found in coastal shallow seawater. so, the aim of this study was isolation and characterization of photobacterium damselae subsp. damselae from edible fish of persian gulf, bandar abbas. material and methods: totally 100 fish ...

Genetic variation within populations depends on population size, spatial structuring, and environmental variation, but is also influenced by mating system. Mangroves are some of the most productive and threatened ecosystems on earth and harbor a large proportion of species with mixed-mating (self-fertilization and outcrossing). Understanding population structuring in mixed-mating species is cri...

several species of magnetotactic bacteria have been discovered recently. these bacteria synthesize intracellular magnetic nanoparticles in specific sizes and shapes and arrange them in chains. these particles called magnetosomes and can be used for drug-delivery, cell-targeting and hyperthermia. magnetotactic bacteria navigate along the magnetic field; this process is known as ‘magnetotaxis’ wh...

the majority of the long stay psychiatric patients who are in need of rehabilitation suffer from schizophrenia. most of them enter the old age with this illness, and besides the consequences of schizophrenia, they are facing the deprivation and misery due to the old age. in contrast to the previous decades in which there was no effective treatment for schizophrenia, today with the immediate dia...

It is generally accepted that local species richness at a site reflects the combined influence of local and regional processes. However, most empirical studies evaluate the influence of either local environmental variables or regional enrichment but not both simultaneously. Here we demonstrate the importance of combining these processes to understand continental-scale richness patterns in breed...

environmental factors mainly temperature are believed to determine the distribution and population dynamics of fusarium species in a natural ecosystem. species may be restricted in their distribution by adaptation to specific sets of soil environmental conditions. population dynamics of five fusarium species representative of different climatic conditions were studied at three levels of tem...

Strains of bacteria with the ability utilizing glyphosate as sole source carbon were isolated from soil exposed to herbicide by culture enrichment method and identified through partial 16S rRNA gene sequence analysis. Sixteen different microbial strains glyphosate-contaminated sites in Kubau local govt. area, Kaduna state. Two strains: BBDD3 BBD4 found be best degraders able withstand up 16.4 m...
