Superior Maximization of Sphenoidotomy With Olfaction Preservation in Endoscopic Endonasal Surgery.

In endoscopic endonasal surgery for anterior skull base lesions, maximizing the anterior sphenoidotomy in the superior part is crucial for direct visualization and creating a wide working corridor. Here, we describe a technique we devised that maximizes upper anterior sphenoidotomy while preserving the olfactory mucosa. Laryngoscope, 2024.

Factors Predicting Renal Outcomes in Hypertensive Emergencies With Severe Renal Impairment: A Single-Center Retrospective Study.

Background And Aims: Hypertensive emergencies, characterized by elevated blood pressure (BP) and multiple organ damage, have poor prognosis. Patients occasionally show gradual improvement in renal function with appropriate antihypertensive treatment despite renal impairment. However, reports analyzing factors predicting prognosis in patients with hypertensive emergencies and severe renal impairment are limited.

Random mutagenesis and disulfide bond formation improved thermostability in microbial transglutaminase.

Microbial transglutaminase (MTG) from Streptomyces mobaraensis is widely used in the food and pharmaceutical industries for cross-linking and post-translational modification of proteins. It is believed that its industrial applications could be further broadened by improving its thermostability. In our previous study, we showed that the introduction of structure-based disulfide bonds improved the thermostability of MTG, and we succeeded in obtaining a thermostable mutant, D3C/G283C, with a T (incubation temperature at which 50% of the initial activity remains) 9 °C higher than that of wild-type MTG.

Low Serum Albumin Levels are Associated with Short-Term Recurrence of Arteriovenous Fistula Failure.

Background: Vascular access intervention therapy (VAIVT) is widely used as a treatment for arteriovenous fistula (AVF) failure. However, recurrent AVF failure is a major concern for dialysis patients. By prospectively observing patients after an initial VAIVT, we attempted to identify risk factors for developing restenosis of AVF.
