plant growth-promoting rhizobacteria (pgpr) is an alternative to chemical pesticides against harmful microorganisms especially soil-borne diseases. rhizoctonia solani is one of the most important soil-borne fungal pathogens that causes serious damages to important crops. in this study, to screen successful pseudomonas bacterial isolates, the inhibition of pathogen growth was evaluated in-vitro....

evaluation of changes present in soil and water resources due to operation implement of floodwater spreading is necessary to assess their positive or negative resultant effect. rate of the internal sediment to diversion spreader channels, surface sedimentation and aggregation of the spreading field depth are most important effective attributes on the yield of floodwater spreading systems. these...

background :cytotoxic t lymphocyte-associated antigen-4 (ctla-4) is an important negative regulator of t-cell responses. the -1722tc polymorphism of the ctla-4 gene may be associated with systemic lupus erythematosus (sle) risk, but related results from previous studies have been inconsistent. we carried out a meta-analysis to assess this association more precisely.   methods : a systematic sea...

aim : this study evaluated the association between serum endothelin- 1 level and symptoms, clinical examination, laboratory and cardio-respiratory parameters, in patients with cirrhosis compared to controls. background : cirrhosis is associated with significant portal, pulmonary and systemic vascular abnormities. recent studies have suggested that endothelin -1 may have a significant role in th...
