On the difficulty of finding spines [PDF]

open access: yes, 2018
We prove that the set of symplectic lattices in the Siegel space $\mathfrak{h}_g$ whose systoles generate a subspace of dimension at least 3 in $\mathbb{R}^{2g}$ does not contain any $\mathrm{Sp}(2g,\mathbb{Z})$-equivariant deformation retract of ...

Preliminary Study of Reaction Conditions for the Synthesis of AA-2G by Cyclodextrin Glucosyltransferase

open access: yesShipin gongye ke-ji, 2023
To investigate the effect of cyclodextrin glucosyltransferase (CGTase) produced by the recombinant strain pET-28a(+)-cgt-T1/BL21 (DE3) on the synthesis of 2-O-α-D-glucoside (AA-2G), the recombinant protein CGTase-T1 was expressed in the fermentation ...

Anti-Allergic Activity of Monoacylated Ascorbic Acid 2-Glucosides

open access: yesMolecules, 2017
2-O-α-d-Glucopyranosyl-l-ascorbic acid (AA-2G) is one of the stable ascorbic acid (AA) derivatives known as provitamin C agents. We have previously synthesized two types of monoacylated derivatives of AA-2G, 6-O-acyl-2-O-α-d-glucopyranosyl-l-ascorbic ...

Projective Normality Of Algebraic Curves And Its Application To Surfaces [PDF]

open access: yes, 2006
Let $L$ be a very ample line bundle on a smooth curve $C$ of genus $g$ with $\frac{3g+3}{2}\max\{2g+2-4h^1(C,L), 2g-\frac{g-1}{6}-2h^1(C,L)\}$. Let $C$ be a triple covering of genus $p$ curve $C'$ with $C\stackrel{\phi}\to C'$ and $D$ a divisor on $C ...

Hypergravity as a gravitational therapy mitigates the effects of knee osteoarthritis on the musculoskeletal system in a murine model.

open access: yesPLoS ONE, 2020
Insights into the effects of osteoarthritis (OA) and physical interventions on the musculoskeletal system are limited. Our goal was to analyze musculoskeletal changes in OA mice and test the efficacy of 8-week exposure to hypergravity, as a replacement ...
