Lactobacillus reuteri strain 121 uses sucrose for synthesis of a unique, soluble glucan ('reuteran') with mainly alpha-(1-->4) glucosidic linkages. The gene (gtfA) encoding this glucansucrase enzyme had previously been characterized. Here, a detailed biochemical and molecular analysis of the GTFA enzyme is presented. This is believed to be the first report describing reuteransucrase enzyme kine...

this paper describes a methodology in designing high-performance concrete for simply supported beams, using a hybrid optimization strategy based on a variable neighborhood search threshold acceptance algorithm. three strategies have been applied to discrete optimization of reinforced concrete beams: variable neighborhood descent (vnd), reduced neighborhood search (rns) and basic variable neighb...

Recently, we and other groups reported in acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) a strong correlation between cytogenetic rearrangements leading to 17p deletion, a typical form of dysgranulopoiesis combining pseudo-Pelger-Huët hypolobulation and small vacuoles in neutrophils, and p53 mutation. To gain further insight into this "17p-syndrome," we studied 17 cases of AML ...

abstractthis study investigates ‘repetition’ in the english translation of the arabic novel, adrift on the nile (1993). it aims to explore the communicative functions of ‘repetition’ and to see if these functions have been maintained or lost in the process of translating the novel. in addition, it seeks to find the translation strategies used in rendering ‘repetition’. to achieve this aim, a de...

background aesthetic surgery procedures have been performed at dramatically increased rates in recent years in iran. few researches exist documenting the usage of body image coping strategies and its relationship in seeking surgery. methods the present research examined data from 90 aesthetic surgery participants (30 ss each in invasive, minimally-invasive, and control groups). assessed subject...

(TD)-deletion is a well-known variable phonological process subject to the influence of both external social factors and internal structural constraints, including phonetic environmental and morphosyntactic effects. Its profile of variation has been widely investigated in American English dialects. However, it interacts with another grammatical process -the affixation of the regular Pasttense m...

We report two families with an autosomal dominant syndrome of abnormalities of the hands and feet, short palpebral fissures, and variable microcephaly with learning disability. Between a third and a quarter of cases are born with oesophageal atresia, duodenal atresia, or both. Individual patients have hypoplastic thumbs or congenital heart disease. The phenotype of the syndrome reported here is...
