Besides their catalysis, specific interactions between starch/glycogen processing enzymes and their substrates have been reported. Multiple branching enzyme (BE) isoforms, BE1, BE2, and BE3, have been found in a limited number of cyanobacterial species that are characterized by amylopectin accumulation. Seven surface binding sites (SBSs) located away from the active site have been identified in crystal structures of cyanobacterial BE1 from Crocosphaera subtropica (Cyanothece sp.) ATCC 51142 (51142BE1). In the present study, binding affinity toward amylopectin, amylose, and glycogen was investigated for wild-type 51142BE1 and its mutants (residues at SBSs important for sugar-binding were replaced by alanine). These enzymes showed retarded mobility during electrophoresis in non-denaturing polyacrylamide gels in the presence of polysaccharides. This was caused by interactions between the enzymes and the polysaccharides, enabling calculation of the dissociation constants (Kd values) of the enzymes toward the polysaccharides. Mutational analysis indicated that particular domains of the protein (domains A and C) were involved in the polysaccharide binding. Kd values toward the polysaccharides were also measured for 10 BE isoforms (five BE1, three BE2, and two BE3) from 5 cyanobacterial strains. All BEs displayed much lower Kd values (higher affinity) toward amylopectin and amylose than toward glycogen, as described for plant BEs. In addition, one BE2 displayed exceptionally high Kd values (low affinity), while two BE3 exhibited multiple Kd values to all polysaccharides. These results could be ascribed to sequence variations in the SBSs, irrespective of the catalytic specificity.Major pulmonary resection has been successfully performed after pulmonary endarterectomy for chronic thromboembolic pulmonary hypertension in a few cases. Anacetrapib A pulmonary nodule was detected in a 68-year-old man with a diagnosis of chronic thromboembolic pulmonary hypertension. After pulmonary hypertension was resolved with pulmonary endarterectomy, left upper lobe trisegmentectomy was performed for small lung cancer. Dissection of the pulmonary artery was carefully performed with a possibility of a fragile state on the arterial wall due to previous pulmonary endarterectomy. Pathologically, the arterial media with an uneven thickness was exposed to the vascular lumen in the resected pulmonary artery.Tricuspid valve replacement is commonly performed using biologic or mechanical prostheses. Partial or complete valve replacement using mitral homograft tissue has also been described. Anecdotal reports exist of valve replacement using a pulmonary homograft within a cylinder. This report describes a technique for native or prosthetic valve replacement using a freehand scalloped pulmonary homograft. Late follow-up confirmed the efficacy of this surgical strategy.
The association of hospital volume with outcomes has been assessed previously for patients with non-small cell lung cancer (NSCLC), but there are limited data on the cumulative effect of travel burden and hospital volume on treatment decisions and survival outcomes. We used the National Cancer Database to evaluate this relationship in early-stage NSCLC.

Outcomes of interest were compared between 2 propensity-matched groups with stage I NSCLC patients in the bottom quartile of distance travelled who underwent surgery at low-volume centers (Local) and those in the top quartile of distance travelled who received surgery at high-volume centers (Distant). Outcomes included type of resection (anatomic or nonanatomic), time to resection (< or ≥8 weeks), number of lymph nodes examined (< or ≥10 nodes) and R0 resection.

We identified 3325 Local patients who travelled 2.3 miles (interquartile range [IQR] 1.4-3.3 miles) to centers that treated 10.5 (IQR 6.5-16.5) stage I NSCLCs/year and 3361 Distant patients who travelled 40.0 miles (IQR 29.1-63.4 miles) to centers treating 56.9 (IQR 40.1-84.7) stage I NSCLCs/year. Local patients were less likely to receive surgery <8 weeks post-diagnosis, have ≥10 lymph nodes examined during surgery, and undergo an R0 resection (all P < .01). Distant patients had shorter hospital stays and superior median survival, both P < .01.

Patients travelling longer distances to high-volume centers receive better and more timely surgical care, leading to shorter hospital stays and improved survival outcomes. Regionalization of lung cancer care by improving travel support to larger treatment facilities may help improve early-stage NSCLC outcomes.

Donors without major underlying diseases are selected after medical screening. A 44-year-old man donated his right lower lobe to his sibling with idiopathic interstitial pneumonia. Although he was free of any major medical problems before transplantation, fibrotic changes appeared in both the donated lung and the donor's remaining lungs in a case of familial interstitial pneumonia. For living-donor lobar lung transplantation for idiopathic interstitial pneumonia, donor candidates should be informed of the potential issue of a familial disease.
In patients with hypertrophic obstructive cardiomyopathy, atrial fibrillation is associated with heart failure and increased late mortality. However, the role of surgical ablation in these patients is not well defined. The aim of this study was to evaluate the efficacy of the concomitant Cox-Maze IV procedure in patients undergoing septal myectomy for hypertrophic obstructive cardiomyopathy.

Between 2005 and 2019, 347 patients who underwent septal myectomy at a single institution (Washington University School of Medicine, Barnes-Jewish Hospital, St Louis, MO) were retrospectively reviewed. For patients with hypertrophic obstructive cardiomyopathy and atrial fibrillation who underwent a concomitant Cox-Maze IV procedure, freedom from atrial tachyarrhythmias (ATAs) on or off antiarrhythmic drugs (AADs) was evaluated annually. Predictors of ATA recurrence were identified using Fine-Gray regression, with death as a competing risk.

A total of 42 patients underwent concomitant septal myectomy and Cox-Maze IV procedures.
