Strains of Lactobacillus plantarum, Weissella cibaria/confusa, Lactobacillus brevis, Pediococcus pentosaceous, Lactobacillus sp. and Enterococcus faecium/faecalis were identified from raw tomatoes by Biolog System, partial 16S rRNA gene sequence and subjected to typing by Random Amplified Polymorphic DNA-Polymerase Chain Reaction (RAPD-PCR) analysis. Ten autochthonous strains were singly used t...

nowadays brain tumors remain as a significant cause of morbidity and mortality and are often treatment refractory. the grading of brain tumor has an important implication in clinical management. currently, magnetic resonance spectroscopy (mrs) is an important modality in evaluating and grading brain tumors. the aim of this study is  evaluation of metabolites in the differentiation of brain tumo...

abdominal mass is one of the commonest clinical findings in children. the purpose of this study was to evaluate abdominal masses in different age groups in a referral children surgical center. we retrospectively reviewed records of 325 patients (57% boys, mean age 37.7 months) admitted to amir kabir hospital in period of 12 years for abdominal mass surgery. the 4 most common abdominal masses wa...

Dissolved organic matter (DOM) in glacier runoff is aliphatic-rich, yet studies have proposed that DOM originates mainly from allochthonous, aromatic, and often aged material. Allochthonous (OM) exposed to ultraviolet radiation both atmospheric transport post-deposition on the surface. Thus, we evaluate photochemistry as a mechanism account for compositional disconnect between allochthonous OM ...

background imaging plays a critical role not only in the detection, but also in the characterization of lung masses as benign or malignant. objectives to determine the diagnostic accuracy of dynamic magnetic resonance imaging (mri) in the differential diagnosis of benign and malignant lung masses. patients and methods ninety-four masses were included in this prospective study. five dynamic seri...
