Expression and significance of Cyr61 in distant metastasis cells of human primary salivary adenoid cystic carcinoma.

Objective: The objective of this study was to examine the expression of cysteine-rich protein 61 (Cyr61) in the distant metastatic tumor cells of human primary salivary adenoid cystic carcinoma (SACC) and its relationship with tumor angiogensis and metastasis.

Study Design: The experimental group comprised 35 paraffin-embedded tumor specimens of distant metastasis from primary SACC, with their corresponding primary tumor tissues and matched normal salivary gland tissues used as the control groups. Immunohistochemical staining was used to detect the expression of Cyr61 and vascular endothelial growth factor in the experimental and control groups.

Expression of Cyr61 in primary salivary adenoid cystic carcinoma and its relation to Ki-67 and prognosis.

Cysteine-rich protein 61 (Cyr61) selectively binds heparin and insulin-like growth factors and mediates a variety of biological actions, including cell adhesion, differentiation, proliferation, migration, angiogenesis, and tumorigenesis. Cyr61 is also a prognostic factor for tumor progression and survival of individuals with various types of tumors. This study investigated the relationship between the expression level of Cyr61 and clinicopathological features, as well as the prognostic significance of Cyr61 expression in human salivary adenoid cystic carcinoma (SACC).

Suppression of spirals and turbulence in inhomogeneous excitable media.

Suppression of spiral and turbulence in inhomogeneous media due to local heterogeneity with higher excitability is investigated numerically. When the inhomogeneity is small, control tactics by boundary periodic forcing (BPF) is effective against the existing spiral and turbulence. When the inhomogeneity of excitability is large, a rotating electric field (REF) is utilized to "smooth" regional heterogeneity based on driven synchronization.

Influences of periodic mechanical deformation on spiral breakup in excitable media.

Influences of periodic mechanical deformation (PMD) on spiral breakup that results from Doppler instability in excitable media are investigated. We present a new effect: a high degree of homogeneous PMD is favored to prevent the low-excitability-induced breakup of spiral waves. The frequency and amplitude of PMD are also significant for achieving this purpose.
