somatostatin-like immunoreactivity (SLI) was assessed simultaneously in an in vivo dog model. The hepatic extraction of this peptide was 29.4+±2.3% and was similar for endogenous and infused exogenous SLI. The renal extraction was 62.3±+5%. The renal clearance of SLI was significantly greater than that of inulin indicating that the peptide is handled by peritubular uptake from postglomerular bl...

Somatostatin-like immunoreactivity (SLI) is widely distributed in tissues and biological fluids. To determine whether SLI is also present in amniotic fluid, samples obtained by amniocentesis from 30 normal and 27 abnormal pregnancies were studied by radioimmunoassay. Direct incubation of [(125)I-Tyr(1)]tetradecapeptide somatostatin (SRIF) with amniotic fluid resulted in 89% tracer degradation. ...

These studies were performed to assess the contribution of the pancreas to the somatostatin-like immunoreactivity (SLI) circulating in arterial and portal venous plasma. Basal SLI concentrations in arterial, pancreatic venous, and portal venous plasma were 95 +/- 9, 277 +/- 32, and 130 +/- 12 pg/ml, (means +/- SEM), respectively. Measurement of pancreatic and portal venous blood flow (5 +/- 1 v...

Co-morbidity of Developmental Coordination Disorder (DCD) in children with specific language impairment (SLI) and the impact of DCD on quality-of-life (QOL) was investigated in 65 5-8 year old children with SLI (43 boys, age 6.8±0.8; 22 girls, age 6.6±0.8). The prevalence of DCD was assessed using DSM-IV-TR criteria (American Psychiatric Association (APA), 2000) operationally defined in the cli...

BACKGROUND AND PURPOSE This study aims to investigate the association between insulin resistance (IR) and silent lacunar infarction (SLI) in healthy adults. METHODS We recruited 2326 healthy Korean adults who took health checkups, including a brain magnetic resonance imaging. SLI was defined as an infarction measuring 0.3 to 1.5 cm in diameter that was localized in the territory of perforatin...

The goal of this study was to determine whether bilingual children with specific language impairment (SLI) are similar to monolingual age mates with SLI, in each language. Eight French-English bilingual children with SLI were compared to age-matched monolingual children with SLI, both English and French speaking, with respect to their use of morphosyntax in language production. Specifically, us...

Autism spectrum disorder (ASD) and specific language impairment (SLI) are developmental disorders exhibiting language deficits, but it is unclear whether they arise from similar etiologies. Language impairments have been described in family members of children with ASD and SLI, but few studies have quantified them. In this study, we examined IQ, language, and reading abilities of ASD and SLI ch...

SLI-1, a Caenorhabditis elegans homologue of the proto-oncogene product c-Cbl, is a negative regulator of LET-23-mediated vulval differentiation. Lack of SLI-1 activity can compensate for decreased function of the LET-23 epidermal growth factor receptor, the SEM-5 adaptor, but not the LET-60 RAS, suggesting that SLI-1 acts before RAS activation. SLI-1 and c-Cbl comprise an N-terminal region (te...

This thesis is in two parts: the first focuses on theories of SLI and the development of argument structure while the second focuses on intervention. Chapter 1 reviews experimental findings and theories of SLI and finds that while some areas of language are well-researched, others (including argument structure) have received relatively little attention. Chapter 2 reviews the literature regardin...
