Multi-hop structure and broadcast channel of wireless sensor networks necessitate error control schemes to achieve reliable data transmission. The energy efficiency of error control schemes should be considered because of the strict energy constraints of wireless sensor networks. Wireless sensor networks require simple and facile error control schemes(More)
AIMS Inflammation plays a role in the genesis and perpetuation of atrial fibrillation (AF). Interleukin (IL)-18 is a pleiotropic proinflammatory cytokine with a central role in the inflammatory cascade. We hypothesize that the circulating IL-18 concentration is elevated in AF patients. METHODS AND RESULTS In a case-control study design, 56 cases with AF(More)
BACKGROUND Neuroendocrine carcinoma (NEC) of the breast, a pathologic entity newly defined in the 2003 World Health Organization classification of tumors, is a rare type of tumor that is not well recognized or studied. The purpose of this first case-controlled study is to reveal the clinicopathologic features, therapeutic response, and outcomes of patients(More)
Luminal closure and embryo apposition are essential for blastocyst attachment during early pregnancy. In our preliminary microarray results (unpublished data), sodium-potassium adenosine triphosphatase (Na/K-ATPase) β1 (Atp1b1) was highly expressed in mouse uterus on Days 3 and 4 of pregnancy. However, expression and regulation of Atp1b1 in the mammalian(More)
High radiation dose in computed tomography (CT) scans increases the lifetime risk of cancer and has become a major clinical concern. Recently, iterative reconstruction algorithms with total variation (TV) regularization have been developed to reconstruct CT images from highly undersampled data acquired at low mAs levels in order to reduce the imaging dose.(More)
PURPOSE To investigate the protein expression of Twist, Snail, and Slug in oral squamous cell carcinoma (OSCC) samples and evaluate the potential correlation between the expression status and clinicopathologic features in patients with OSCC. PATIENTS AND METHODS Twist, Snail, and Slug protein expression was assessed by immunohistochemistry in a total of(More)
BACKGROUND The role of promoter methylation in the inactivation of E-cadherin (E-cad) in salivary gland adenoid cystic carcinoma (ACC) is unknown. The objective of this study was to determine the role and potential clinical implications of promoter methylation of E-cad in salivary gland ACC. METHODS The promoter methylation status of E-cad was determined(More)
BACKGROUND The aim of this study was to investigate the expression of the apoptosis-inhibitory Bcl-2 protein and the apoptosis-promoting Bax protein and to identify their association with the clinical parameters and prognosis of the patients with oral squamous cell carcinoma (OSCC). METHODS The expression of Bcl-2 and Bax proteins was evaluated by(More)
Salidroside (Sal) is a natural antioxidant extracted from the root of Rhodiola rosea L. that elicits neuroprotective effects in vivo and in vitro. Tyrosol galactoside (Tyr), an analog of Sal, was recently synthesized in our laboratory. The purpose of the current study was to investigate and compare the neuroprotective effects of Sal and Tyr against focal(More)
G-protein-coupled receptor 30 (GPR30)/G-protein-coupled estrogen receptor is a novel estrogen membrane receptor that localizes to the cell membrane and endoplasmic reticulum. GPR30 is widely distributed and has numerous physiological functions in the central nervous system. We found that GPR30 is highly expressed in the basolateral amygdala (BLA).(More)
