Sequential injection immunoassay systems for environmental measurements based on the selective immunoreaction between antigen and antibody were described. A sequential injection analysis (SIA) technique is suitable to be applied for the procedure of enzyme-linked immunosorbent assay (ELISA), because the washing and the addition of reagent solutions can be automated by using a computer-controll...

The ratio of Rashba and Dresselhaus spin splittings of the (001)-grown GaAs/AlGaAs quantum wells (QWs), investigated by the spin photocurrent spectra induced by circular photogalvanic effect (CPGE) at inter-band excitation, has been effectively tuned by changing the well width of QWs and by inserting a one-monolayer-thick InAs layer at interfaces of GaAs/AlGaAs QWs. Reflectance difference spect...

In vivo assessment of tumor glucose catabolism by positron emission tomography (PET) has become a highly valued study in the medical management of cancer. Emerging technologies offer the potential to evaluate in vivo another aspect of cancer carbohydrate metabolism related to the increased anabolic use of monosaccharides like sialic acid (Sia). Sia is used for the synthesis of sialylated oligos...

Previous work has shown that nude (nu/nu) mice additionally immunosuppressed by splenectomy, sublethal irradiation, and treatment with antiasialo GM1 antiserum (SIA-nu/nu mice) have no detectable natural killer activity and allow the growth of human malignant lymphoblasts. We show here that all SIA-nu/nu mice engrafted intravenously with 5 x 10(6) malignant lymphoblasts originally derived from ...

Streptococcus pneumoniae is a human-adapted pathogen that encounters terminally sialylated glycoconjugates and free sialic acid (Sia) in the airways. Upon scavenging by the bacterial sialidase NanA, Sias serve as carbon sources for the bacteria. Unlike most animals in which cytidine-monophosphate-N-acetylneuraminic acid hydroxylase (CMAH) converts Sia N-acetylneuraminic acid (Neu5Ac) into N-gly...

purpose : to evaluate the safety and efficacy of limbal relaxing incisions (lris) for corneal astigmatism correction during phacoemulsification methods : 24 eyes of 24 patients with the mean age of 65.71 years (range: 55 to 83 years) with senile cataracts and mean corneal astigmatism of 1.9±0.83 diopters (d) (range: 1.5 to 3.5 d) were included in this study. all lris were performed during phaco...

Riassunto: Sia X un sottoinsieme di r elementi di uno spazio di Hilbert H e sia V0 il sottospazio chiuso generato dall’iterazione di X mediante l’operatore unitario U = (U1, . . . , Ud). Analogamente sia V1 ⊃ V0 il sottospazio generato da un insieme Y con s > r elementi. Si descrivono alcuni metodi per costruire un insieme Γ con s − r elementi che generi in modo simile il complemento ortogonale...

A remarkable development in twentieth-century mathematics is smooth infinitesimal analysis ("SIA"), introducing nilsquare and nilpotent infinitesimals, recovering the bulk of scientifically applicable classical analysis ("CA") without resort to the method of limits. Formally, however, unlike Robinsonian "nonstandard analysis", SIA conflicts with CA, deriving, e.g., "not every quantity is either...

Social Impact Assessment (SIA) facilitates sustainable and equitable consideration of social issues in transport infrastructure planning. However, SIA practitioners face significant constraints ...
