From symplectic cohomology to Lagrangian enumerative geometry

We build a bridge between Floer theory on open symplectic manifolds and the enumerative geometry of holomorphic disks inside their Fano compactifications, by detecting elements in symplectic cohomology which are mirror to Landau-Ginzburg potentials. We also treat the higher Maslov index versions of LG potentials. We discover a relation between higher disk potentials and symplectic cohomology rings of anticanonical divisor complements (themselves related to closed-string Gromov-Witten invariants), and explore several other applications to the geometry of Liouville domains.Comment: 47 pages, 13 figures; v2: reference fixes, minor correction

Regeneration of the periodontium for preservation of the damaged tooth

The population of the world grows every year, and life expectancy tends to increase. Thus, longterm preservation of teeth in aged individuals is an urgent issue. The main causes of tooth loss are well known to be periodontitis, caries, fractures, and orthodontic conditions. Although implant placement is a widely accepted treatment for tooth loss, most patients desire to preserve their own teeth. Many clinicians and researchers are therefore challenged to treat and preserve teeth that are irreversibly affected by deep caries, periodontitis, fractures, and trauma. Tissue engineering techniques are beneficial in addressing this issue; stem cells, signal molecules, and scaffolds are the main elements of such techniques. In this review, we describe these three elements with respect to their validation for regeneration of the periodontium and focus particularly on the potency of diverse scaffolds. In addition, we provide a short overview of the ongoing studies of 4- methacryloxyethyl trimellitate anhydride/methyl methacrylate-tri-n-butyl-borane resin including calcium chloride or hydroxyapatite for periodontium regeneration

The Roles of Angiotensin II in Stretched Periodontal Ligament Cells

The loading caused by occlusion and mastication plays an important role in maintaining periodontal ligament (PDL) tissues. We hypothesized that a loading magnitude would be involved in the production of biological factors that function in the maintenance of PDL tissues. Here, we identified up-regulated gene expressions of transforming growth factor-β1 (TGF-β1), alkaline phosphatase (ALP), and angiotensinogen in human PDL fibroblastic cells (HPLFs) that were exposed to 8% stretch loading. Immunolocalization of angiotensin I/II (Ang I/II), which was converted from angiotensinogen, was detected in rat PDL tissues. HPLFs that were stimulated by Ang II also increased their gene expressions of TGF-β1 and ALP. Furthermore, the antagonist for Ang II type 2 receptor, rather than for type 1, significantly inhibited gene expressions induced by the stretch loading. Analysis of these data suggests that Ang II mediates the loading signal in stretched HPLFs to induce expressions of TGF-β1 and ALP
