[Emergent Off-pump Coronary Artery Bypass Grafting in a Patient with Situs Inversus Totalis: Report of a Case].

Dextrocardia associated with situs inversus totalis is a rare congenital anomaly. We herein report a patient with this condition and ischemic coronay artery disease who underwent emergency surgical myocardial revascularization. A 76-year-old man was admitted to our hospital with a diagnosis of unstable angina pectoris.

[Spontaneous Renal Rupture of Acquired Cystic Kidney Disease after Coronary Artery Bypass Grafting:Report of a Case].

We described a hemodialysis patient with spontaneous renal rupture of acquired cystic kidney disease (ACKD) after off-pump coronary artery bypass grafting(OPCAB). A 53-year-old man was transfer to our hospital with a diagnosis of unstable angina pectoris. He became ventilated due to congestive heart failure 3 days and underwent OPCAB on schedule 6 days after hospitalization.

High metabolic heterogeneity on baseline 18FDG-PET/CT scan as a poor prognostic factor for newly diagnosed diffuse large B-cell lymphoma.

Metabolic heterogeneity (MH) can be measured using 18F-fluorodeoxyglucose (18FDG) positron emission tomography/computed tomography (PET/CT), and it indicates an inhomogeneous tumor microenvironment. High MH has been shown to predict a worse prognosis for primary mediastinal B-cell lymphoma, whereas its prognostic value in diffuse large B-cell lymphoma (DLBCL) remains to be determined. In the current study, we investigated the prognostic values of MH evaluated in newly diagnosed DLBCL.

[Coronary Artery Bypass Grafting to the Left Anterior Descending Artery via Anterior Minithoracotomy after Surgery for Acute Papillary Muscle Rupture;Report of a Case].

We presented a case with chronic occlusion of the left anterior descending artery(LAD) after mitral valve replacement (MVR). An 80-year-old man was transferred to our hospital with a diagnosis of acute myocardial infarction. Before coronary angiography, the patient suddenly fell in a state of cardiogenic shock.

Serum level of soluble interleukin-2 receptor is positively correlated with metabolic tumor volume on F-FDG PET/CT in newly diagnosed patients with diffuse large B-cell lymphoma.

Diffuse large B-cell lymphoma (DLBCL) is the most frequent subtype of non-Hodgkin lymphoma. High total metabolic tumor volume (TMTV) calculated using F-FDG PET/CT images at diagnosis predicts poor prognosis of patients with DLBCL. However, high cost and poor access to the imaging facilities hamper wider use of F-FDG PET/CT.

Diagnostic value of ¹⁸F-FDG PET/CT for lymph node metastasis of esophageal squamous cell carcinoma.

Purpose: This study investigated the diagnostic accuracy of hybrid positron-emission tomography/computed tomography (PET/CT) for lymph node (LN) metastasis of esophageal cancer. We also investigated the correlation between the size of metastatic nests and the detection by PET/CT.

Methods: Two hundred and fifty-eight patients with esophageal squamous cell carcinoma who underwent esophagectomy with two- or three-field radical lymphadenectomy were analyzed retrospectively.

One-bottle silane coupling agent containing 4-META.

The effectiveness of commercial and experimental silane coupling agents was evaluated by measuring their shear bond strengths to a ceramic disk. Experimental one-bottle silane coupling agents were prepared using 3-MPTS, 4-META, and resin monomers. The surfaces of two ceramic disks (IPS e-max, Ivoclar Vivadent AG, Schaan, Lichtenstein) were treated by a silane coupling agent to bond them to each other; this bonding was mediated by a commercial flowable resin composite (Clearfil Majesty LV, Kuraray, Tokyo, Japan).

Diagnostic accuracy of lymph node metastasis depends on metabolic activity of the primary lesion in thoracic squamous esophageal cancer.

Unlabelled: The metabolic activity of the primary tumor is an important variable in (18)F-FDG PET interpretation for presurgical staging, because this activity is likely to affect the possibility of detection of malignant involvement in lymph nodes (LNs). The purpose of this study was to reevaluate the diagnostic accuracy of (18)F-FDG PET/CT for the presurgical staging of esophageal squamous cell carcinoma (SCC) in correlation with the (18)F-FDG avidity of the primary lesions.

Methods: One hundred fifty-six patients (mean age ± SD, 61.

Multimodality evaluation of cardiac paraganglioma.

We report 2 rare cases of primary cardiac paraganglioma demonstrated with multimodality imaging. Both a 46-year-old woman who presented with hypertension (case 1) and a 46-year-old woman without any symptoms (case 2) had mediastinal tumors depicted by CT and MRI. Both cases showed intense focal uptakes in the tumors with iodine-123-meta-iodobenzylguanidine SPECT.

Direct projections from the central amygdaloid nucleus to the mesencephalic trigeminal nucleus in rats.

The amygdala is activated by fear and plays an important role in the emotional response to life-threatening situations. When rats feel threatened, they respond by biting fiercely. Bite strength is regulated by the trigeminal motor nucleus and the mesencephalic trigeminal nucleus (Me5).

Diffusion of GM primer and dentin adhesive into EDTA-conditioned dentin.

The aim of this study was to investigate the diffusion of red-stained experimental GM primer and blue-stained dentin bonding agent into EDTA-conditioned dentin and the effect of GM priming on contraction gap formation. After GM priming at 0, 35, 70, or 100 vol%, marginal adaptation was evaluated by measuring the wall-to-wall contraction gap width of a light-activated resin composite (Palfique Estelite, Tokuyama Dental, Japan) mediated with a commercial dentin bonding agent (Clearfil Photo Bond, Kuraray Medical, Japan). Contraction gap formation was completely prevented when treated with 35 vol% GM primer.

Production of polyselenodipenicillamines, unique selenium compounds.

Selenite (H(2)SeO(3)) reacts with thiol compounds (RSH) under acidic conditions to form selenotrisulfides (RSSeSR, i.e. monoselenodithiols).

The locus coeruleus projects to the mesencephalic trigeminal nucleus in rats.

The ganglion-cells in the mesencephalic trigeminal nucleus (Me5) process proprioceptive signals from the masticatory muscles and the periodontal ligaments, and are considered to regulate the rhythm of biting and bite strength. The locus coeruleus (LC) is the major source of noradrenergic projections in the brain and plays an important role in stressful situations and aggressive behavior. The two nuclei are adjacently located to each other in the lateral part of the periaqueductal gray matter of the fourth ventricle.

Measurement of shear bond strength to intact dentin.

Previously, we reported that the integrity of a resin composite restoration deteriorated when the dentin cavity wall was decalcified by conditioning. In this study, to evaluate the bonding between dentin adhesive and non-decalcified dentin surface, we experimented with a novel method of using a high-pressure water spray device to prepare smear layer-free dentin surfaces. When the smear layer was removed, shear bond strength significantly increased regardless of the removal method employed.

Can hybrid FDG-PET/CT detect subclinical lymph node metastasis of esophageal cancer appropriately and contribute to radiation treatment planning? A comparison of image-based and pathological findings.

Background: We aimed to determine the appropriateness of adding 18F-fluorodeoxyglucose (FDG)-positronemission tomography (PET) to computed tomography (CT) and other pre-existing diagnostic imaging modalities for detecting subclinical lymph node metastasis of esophageal cancer, by comparing images from these modalities with the results of histopathological analysis.

Methods: Twenty patients who received radical surgery for squamous cell carcinoma of the esophagus were examined by PET-CT, and endoscopic ultrasound (EUS) examination before surgery. Based on these diagnostic modalities, the clinical target volume (CTV) was set as the gross tumor volume (GTV) plus a 1-cm margin.

In vitro comparison of three caries dyes.

Purpose: To evaluate the efficacy of a conventional and newly-developed caries detector (Caries Check) by measuring the Vickers microhardness (VMH) and DIAGNOdent value of the dentin cavity wall of extracted human teeth after removing carious dentin that was stained by the caries detector.

Methods: 30 human teeth with coronal dentin caries extending halfway through the dentin were sectioned and extracted for use in this study. As a control, the longitudinal section of a caries-free extracted human tooth was prepared.

Role of oxidative stress in hypertrophied myoblasts stimulated by isoproterenol.

Objective: Hydrogen peroxide (H(2)O(2)), one of the oxyradical members, has been shown to have insulin-like effects, and endogenous H(2)O(2) may have the ability to improve impaired glucose metabolism. As a mechanism contributing to progression of hypertrophy, we hypothesized that the formation of H(2)O(2) to improve glucose uptake could be an oxidative stress resulting in apoptotic cell death.

Methods: We used cultured myoblasts (H9c2) stimulated by isoproterenol as a model to focus on glucose metabolism, oxidative stress, apoptosis, and extracellular signal-regulated protein kinases (ERKs) expression.

Priming effects of triethylene glycol and triethylene glycol monomethacrylate on dentin bonding.

The objective of this study was to evaluate the effects of triethylene glycol (TEG) and triethylene glycol monomethacrylate (TEGMA) solutions as dentin primers on dentin bonding. To this end, wall-to-wall polymerization contraction gap width of a resin composite in a cylindrical dentin cavity and shear bond strength to a flat dentin surface were measured. Dentin was pretreated with an experimental dentin bonding system - consisting of 0.

Guinea Pig Maximization Test of tri-ethylene glycol mono-methacrylate.

The aim of this study was to evaluate tri-ethylene glycol mono-methacrylate (TEGMA) in terms of dermatological allergic reaction using a Guinea Pig Maximization Test. Skin reaction was evaluated according to the criteria of International Contact Dermatitis Research Group. TEGMA, as a constituent in new primers, has been reported to contribute to a priming ability similar to that of highly purified glyceryl mono-methacrylate (GM).

Light intensity evaluation of laser-induced fluorescence after caries removal using an experimental caries staining agent.

Objective: The purpose of this study was to evaluate the intensity of fluorescent light reflected from cavity wall dentin, after dentin stained by an experimental caries detecting liquid was removed.

Background Data: The conventional caries detecting liquid tends to penetrate dentin too deeply. On the other hand, DIAGNOdent has gradually gained recognition and established itself as a caries detection device using a laser beam.

Brain-derived neurotrophic factor participates in determination of neuronal laminar fate in the developing mouse cerebral cortex.

Lamina formation in the developing cerebral cortex requires precisely regulated generation and migration of the cortical progenitor cells. To test the possible involvement of brain-derived neurotrophic factor (BDNF) in the formation of the cortical lamina, we investigated the effects of BDNF protein and anti-BDNF antibody separately administered into the telencephalic ventricular space of 13.5-d-old mouse embryos.

Contraction gap versus shear bond strength of dentin adhesive in sound and sclerotic dentins.

To evaluate the effect of a dentin adhesive on sclerotic dentin, contraction gap width and shear bond strength were measured. Dentin cavity wall was pretreated with an experimental dentin bonding system with and without a dentin primer, or with a commercial dentin bonding system. In the experimental dentin bonding groups, contraction gap width of sclerotic dentin was significantly smaller than that of sound dentin when the cavity was not primed with glyceryl monomethacrylate.

Preoperative evaluation of the right gastroepiploic artery using abdominal ultrasonography.

Preoperative evaluation of the right gastroepiploic artery was performed by abdominal ultrasonography to determine whether the graft was adequate for coronary artery bypass. The gastroepiploic artery was used when the graft diameter was greater than 2 mm with pulsatile flow. Postoperative angiography revealed the gastroepiploic artery dominant, and the graft diameter measured by angiography was almost the same size as that of abdominal ultrasonography.

Projections of glutamate decarboxylase positive and negative cerebellar neurons to the pretectum in the cat.

The pretectum is one of the primary visual centers, and plays an important role in the visuomotor reflexes. It also receives projections from the cerebellar nuclei that are considered to regulate these reflexes. Gamma aminobutylic acid (GABA) and glutamate are supposed to be two major neurotransmitters of the projection neurons of the cerebellar nuclei.
