Outer-surface adduct formation and selective separation of -type gallated and -type non-gallated catechins using cucurbit[7]uril.

We found that -type gallated and non-gallated catechins form low water solubility outer-surface adducts with cucurbit[7]uril in aqueous solution, with -type gallated catechins showing a higher tendency to precipitate as outer-surface adducts. By exploiting this phenomenon, we achieved the selective separation of -type gallated and non-gallated catechins in solution.

Conversion surgery for esophageal and esophagogastric junction cancer.

As a result of the recent advances in first-line treatment including chemotherapy, radiation therapy, targeted therapy, and immune checkpoint inhibitor immunotherapy (ICI) for locally advanced/metastatic initially unresectable esophageal and esophagogastric junction cancer, surgery aiming at cure after initial treatment, so-called "conversion surgery" has become more common in this field. Several studies have indicated encouraging survival outcomes for patients after conversion surgery with R0 resection. However, various issues, such the utility and the safety of conversion surgery remain unclear.

Thoracoscopic McKeown esophagectomy in a patient with an azygos lobe.

Background: The azygos lobe is a relatively rare anatomical variation, and there have been no reports, until date, of thoracoscopic McKeown esophagectomy for esophageal cancer in a patient with an azygos lobe. The azygos lobe can be diagnosed by chest X-ray or CT, and is usually not associated with any symptoms. However, surgeons should be aware that transthoracic surgical procedures in patients with an azygos lobe could be associated with a high risk of complications.

Drug-Tea Polyphenol Interaction (III) Incompatibility between Aripiprazole Oral Solution and Green Tea.

The details of incompatibility between aripiprazole (ARIP) oral solution and green tea were examined. When the ARIP oral solution was mixed with a commercial PET bottled green tea beverage, the residual rate of ARIP in the mixed solution decreased to 15.7-17.

Objective and Personalized Assessment of Disease-Related Knowledge Among Patients With Congenital Heart Disease - Development and Validation of the Japanese Version of the Leuven Knowledge Questionnaire for Congenital Heart Disease.

Disease understanding in patients with congenital heart disease is important in transitional and lifelong care. This study aimed to develop the Japanese version of the Leuven Knowledge Questionnaire for Congenital Heart Disease (LKQCHD) and identify factors associated with disease-related knowledge. After confirming the content and face validity of the scale, a questionnaire including the LKQCHD was distributed to 59 eligible patients aged >16 years attending a university hospital.

Characteristics of patients with adult congenital heart disease treated by non-specialized doctors: The potential loss of follow-up.

Background: In the treatment of adult congenital heart disease (ACHD), the transfer of patients from pediatric cardiologists to ACHD cardiologists is of relevance. However, little is known about the clinical courses of ACHD patients that have been referred by non-CHD-specialized doctors (n-CSDs).

Methods: This retrospective cohort study included 230 patients (average age: 37 ± 15.

Unusual double-chambered right ventricle induced by ruptured sinus of Valsalva aneurysm: A case report.

A 54-year-old male with a history of unrepaired ventricular septal defect (VSD) suffered from easy fatigability on exertion. A Levine grade V/VI continuous murmur was auscultated. Transthoracic echocardiogram showed a ruptured sinus of Valsalva aneurysm (SVA) and a significant left-to-right shunting from the ascending aorta to the right ventricle (RV).

A mechanism of a cardiac murmur with respiratory variation in a patient with straight back syndrome.

A 20-year-old male without any symptoms was referred for heart murmur on a medical examination. A thrill was palpable at the upper left sternal border. His cardiac murmur showed respiratory variation.

An early atherosclerotic change detected by an aortic angioscopy in a young patient with coarctation of the aorta: a case report.

The patient was a 19-year-old woman who had experienced headache for 1 year. Soon after birth, ventricular septal defects were diagnosed, the size of which were small, therefore not requiring surgical repair. She also noticed hypertension, with up to 184/110 mmHg of blood pressure.

Importance of identifying the direction of pulmonary venous flow in diagnosing a cavopulmonary window: A case report and review of literature.

A 75-year-old male suffered from dyspnea on exertion. In a referring hospital, cardiac catheterization demonstrated a 25% increase in oxygen saturation between the high superior vena cava (SVC) and the right atrium, suggesting a pre-tricuspid left-to-right shunt. However, neither an intracardiac shunt nor a partial anomalous pulmonary venous connection was detected.

Study of flow rate in pressurized gradient capillary electrochromatography using splitter and separation of peptides using an Amide stationary phase.

A pressurized gradient capillary electrochromatograph using a splitter was constructed. The variation in flow rate during gradient elution was investigated and separations of peptides using an Amide stationary phase were demonstrated. The flow rate, which is one of the important factors to control chromatographic behavior, was increased during the gradient elution, and the mismatching of mobile phase between the column and the resistance tubing derived three variation patterns in the flow rate.
