Regulation of cellulolytic genes by McmA, the SRF-MADS box protein in Aspergillus nidulans.

Cellobiose triggers the production of two endoglucanases, EglA and EglB, in Aspergillus nidulans. The cellulose responsive element (CeRE) cis-element that is essential for induction has been identified on the eglA promoter, but transcription factors that bind to CeRE have not yet been identified. CeRE contained a consensus sequence CC(A/T)6GG for binding of the SRF-type MADS box proteins.

Correlation between plasma brain natriuretic peptide concentration and lung thallium-201 uptake on exercise thallium perfusion images.

The plasma brain natriuretic peptide (BNP) concentration at rest correlates with left ventricular end-diastolic pressure (LVEDP), left ventricular ejection fraction (LVEF), and pulmonary capillary wedge pressure (PCWP). High lung thallium-201 uptake has been reported to be associated with hemodynamic variables such as LVEDP, LVEF, and PCWP. However, there is no study that has investigated the correlation of plasma BNP concentration with lung thallium-201 uptake.

Clinical usefulness of ECG-gated 18F-FDG PET combined with 99mTC-MIBI gated SPECT for evaluating myocardial viability and function.

Objectives: This study sought to evaluate an imaging approach using gated 99mTc-MIBI (MIBI) SPECT and gated 18F-FDG (FDG) PET for assessment of myocardial viability and cardiac function.

Methods: Forty-eight patients (38 men, mean age 68.1 +/- 9.

Assessment of regional wall motion by strain Doppler during biventricular pacing in patients with conventional indications for a pacemaker.

Biventricular pacing therapy is effective in patients with severe congestive heart failure. Strain Doppler imaging (SDI) is a new tool for measuring regional myocardial deformation. We evaluated regional wall motion by strain Doppler imaging in 13 patients who had conventional indications for a pacemaker (74 +/- 6 years old) and in six with NYHA Class III or IV heart failure with a biventricular pacemaker (HF-RV: during right ventricular pacing, HF-BV: during biventricular pacing).

[Assessment of regional wall motion using strain Doppler imaging during right ventricular bifocal pacing in a patient with severe congestive heart failure: a case report].

A 79-year-old man presented with dilated cardiomyopathy and chronic atrial fibrillation. A DDD pacemaker was implanted due to sick sinus syndrome. His left ventricular ejection fraction was 23%.

Prevalence of right bundle-branch block and right precordial ST-segment elevation (Brugada-type electrocardiogram) in Japanese children.

Background: The prevalence of Brugada-type electrocardiogram (ECG) in schoolchildren remains unclear. This study aimed to further investigate this condition.

Methods And Results: We studied the prevalence of Brugada-type ECG in 20,387 children (10,434 males and 9,953 females, 9.

[Brugada syndrome associated with ventricular fibrillation induced by administration of pilsicainide: a case report].

A 56-year-old man with Brugada syndrome presented with ventricular fibrillation induced by administration of pilsicainide. He had syncope at age 46 years, and his uncle suddenly died of unknown cause. He had taken pilsicainide (150 mg/day) for paroxysmal atrial fibrillation, and suffered from syncope due to ventricular fibrillation.

[Factors for successful conversion of atrial fibrillation using intravenous injection of pilsicainide hydrochloride].

Objectives: The factors affecting successful conversion of atrial fibrillation using intravenous injection of pilsicainide hydrochloride are unclear. The efficacy of intravenous injection of pilsicainide hydrochloride and the factors affecting successful conversion of symptomatic atrial fibrillation were investigated.

Methods: Twenty-six patients[21 men, 5 women, 64 +/- 12 years (mean +/- SD)] with electrocardiographically confirmed, symptomatic atrial fibrillation were treated with intravenous injection 1.

Changes in evoked QT intervals according to variations in atrioventricular delay and cardiac function in patients with implanted QT-driven DDDR pacemakers.

In patients with implanted DDD pacemaker, cardiac output is maximal when atrioventricular (AV) delay is set to give the maximum QT interval (QTI). QTI is used as a sensor of a rate-responsive pacemaker and the evoked QTI (eQTI) is measured as the time duration from the ventricular pace-pulse and the T sense point, which is the steepest point of the intracardiac T wave. The relationship between the changes in eQTI according to AV delay variations and cardiac function was studied in 13 patients (74.
