A 79-year-old man with repeated and massive hemoptysis due to bronchiectasis was admitted to our department for surgery. The patient had undergone left upper lobectomy for pulmonary tuberculosis, and descending aortic replacement for Stanford type B aortic dissection. The patient underwent occlusion of the left main bronchus by suturing through median sternotomy. The reasons we did not choose completion pneumonectomy were advanced age, poor physical condition immediately after hemorrhagic shock, and the difficulty of performing pneumonectomy due to previous surgery and anastomotic aneurysm of descending aorta. The postoperative course was uneventful and the patient left the hospital on the 16th postoperative day. The patient did not develop pneumonia or empyema thereafter, but died suddenly of unknown etiology 1.5 years postoperatively. Lung exclusion by suturing a bronchus is thought to be a useful alternative for repeated and massive hemoptysis without pneumonia in a case of difficult lung resection.

More than a century of research shows that spaced learning improves long-term memory. However, there remains debate concerning why that is. A major limitation to resolving theoretical debates is the lack of evidence for how neural representations change as a function of spacing.

Metabolic pathway modeling, essential for understanding organism metabolism, is pivotal in predicting genetic mutation effects, drug design, and biofuel development. Enhancing these modeling techniques is crucial for achieving greater prediction accuracy and reliability. However, the limited experimental data or the complexity of the pathway makes it challenging for researchers to predict phenotypes.

Since 2011, Caribbean territories have experienced massive and repeated sargassum seaweed inundations. Once on shore, sargassum degradation through anaerobic metabolism elicits the release of many noxious molecules, including hydrogen sulfide (HS) and ammonia (NH). HS has been long recognized as a malodorous and highly toxic gas, while chronic exposure has not been extensively explored.

Background: There is a relative paucity of studies examining how the superior capsule reconstruction (SCR) may alter the kinematics of the glenohumeral joint capsule itself, specifically with respect to rotation and translation in the anterior-posterior and superior-inferior planes. This then raises the possibility that the SCR may be having unintended consequences on glenohumeral kinematics. The purpose of this study was to quantify the glenohumeral joint kinematics following Fascia Lata SCR (FL-SCR).
