Saponins are sterols or triterpene glycosides that are widely distributed in plants. The biosynthesis of soybean saponins is thought to involve many kinds of glycosyltransferases, which is reflected in their structural diversity. Here, we performed linkage analyses of the Sg-3 and Sg-4 loci, which may control the sugar chain composition at the C-3 sugar moieties of the soybean saponin aglycones...

AIM To investigate factors causing diabetes recurrence after sleeve gastrectomy (SG) and duodenal-jejunal bypass (DJB). METHODS SG and DJB were performed on rats with diabetes induced by high-fat diet (HFD) and streptozotocin (STZ). HFD was used to induce diabetes recurrence at 4 wk postoperatively. Body weight, oral glucose tolerance test, homeostatic model assessment of insulin resistance (...

Stress grading (SG) layer in cable terminations limits the critical electric field and properties of SG materials are important issues which have to be considered during manufacturing and selecting procedure. In this paper, two different types of (SG) materials are analyzed by both theory and test. According to the applied theory, important parameters as: electrical resistivity, breakdown volta...

In this note we show that the moduli space M(Sg,n) of surface Sg,n of genus g with n punctures, satisfying 3g + n ≥ 5, admits no complete Riemannian metric of nonpositive sectional curvature such that the Teichmüler space T(Sg,n) is a mapping class group Mod(Sg,n)-invariant visibility manifold.

We determine the smooth locus and the locus of canonical singularities in the Cornalba compactification Sg of the moduli space Sg of spin curves, i.e., smooth curves of genus g with a theta characteristic. Moreover, the following lifting result for pluricanonical forms is proved: Every pluricanonical form on the smooth locus of Sg extends holomorphically to a desingularisation of Sg.

Hyposalivation often leads to irreversible and untreatable xerostomia. Salivary gland (SG) stem cell therapy is an attractive putative option to salvage these patients but is impeded by the limited availability of adult human tissue. Here, using murine SG cells, we demonstrate single-cell self-renewal, differentiation, enrichment of SG stem cells, and robust in vitro expansion. Dependent on ste...

Siegesbeckia glabrescens (SG) Makino (Compositae) has been used as a traditional medicine for the treatment of allergic and inflammatory diseases. In the present study, we report the effects and molecular mechanism of an ethanolic extract of SG on cell proliferation, migration and tube formation in vascular endothelial growth factor-A (VEGF-A)-treated human umbilical vein endothelial cells. SG ...

The moduli space Sg of smooth spin curves parameterizes pairs [C, η], where [C] ∈ Mg is a curve of genus g and η ∈ Pic(C) is a theta-characteristic. The finite forgetful map π : Sg → Mg has degree 22g and Sg is a disjoint union of two connected components S+ g and S− g of relative degrees 2g−1(2g +1) and 2g−1(2g − 1) corresponding to even and odd theta-characteristics respectively. A compactifi...

Sleeve gastrectomy (SG) is a surgical weight-loss procedure. Splenic abscess is a rare complication of SG. Four cases of splenic abscess after SG have been reported, all managed by surgical intervention. We report the first documented case of multiple splenic abscesses following SG managed conservatively by an integrated medical treatment.
