Squid male alternative reproductive tactics are determined by birth date.

Alternative reproductive tactics (ARTs) are discontinuous phenotypes associated with reproduction, observed in males of many species. Typically, large males adopt a tactic of competing with rivals for mating, while small males adopt a tactic of stealing fertilization opportunities from the large males. The 'birth date hypothesis', proposing that the date of birth influences the determination of each male's reproductive tactic, has been tested only in teleost fish to date.

Outcomes of endoscopic submucosal dissection for gastroesophageal reflux disease (ESD-G) for medication-refractory gastroesophageal reflux disease: 35 cases underwent ESD-G including 15 cases followed more than 5 years.

Background: Although some kinds of endoluminal surgery for patients with proton pump inhibitor (PPI)-refractory gastroesophageal reflux disease (GERD) have been reported, there are few reports on their long-term outcomes. In 2014, we reported the effectiveness of endoscopic surgery for PPI-refractory GERD, which we invented and named endoscopic submucosal dissection for GERD (ESD-G) in 2008. Thereafter, we accumulated more cases and monitored the patients' condition postoperatively and describe the outcomes herein.

A novel approach for effective superior vena cava isolation using the CARTO electroanatomical mapping system.

Background: Previous studies have demonstrated that some patients have spontaneous right atrium (RA)-superior vena cava (SVC) conduction block, which could be utilized to isolate the SVC effectively by using the Rhythmia mapping system (Boston Scientific). However, employing this approach for SVC isolation using the CARTO electroanatomical mapping system (Biosense Webster) has not yet been clarified. This study aimed to evaluate the safety and efficacy of SVC isolation using the extended early meets late (EEML) tool with the CARTO system.

Treatment strategy and endpoint of catheter ablation for bi-atrial tachycardia after substrate modification ablation in a low voltage zone of the left atrial anterior wall: Long-term results.

Background: The termination of bi-atrial tachycardia (BiAT) via the ablation of the Bachmann's bundle (BB) and mitral isthmus (MI) has been previously reported; however, the strategy and long-term results of catheter ablation for BiAT remain unclear.

Methods: The data of nine patients with BiAT who underwent low voltage zone (LVZ) ablation of the left atrial anterior wall (LAAW) after pulmonary vein isolation were reviewed. Patients with a P wave duration <100 ms during sinus rhythm underwent MI ablation and those with a P wave duration >100 ms underwent BB ablation.

Long-term outcome of ventricular tachycardia ablation in patients who did not undergo programmed electrical stimulation after ablation.

Background: Ventricular arrhythmia inducibility is one of the ideal endpoints of ventricular tachycardia (VT) ablation. However, it may be challenging to implement programmed electrical stimulation (PES) at the end of the procedure under several circumstances. The long-term outcome of patients who did not undergo PES after VT ablation remains largely unknown.

Cardiac perforation due to a fracture of a recalled Accufix bipolar active fixation pacing lead 29 years after implantation: A case report.

The Accufix bipolar active fixation atrial pacing lead (Model 330-801; Telectronics) can have mechanical complications due to a fracture of its J retention wire. An 80-year-old man had the Accufix atrial pacing lead implanted 29 years prior, and surgical removal was required because a part of the lead was perforating the apex of the right ventricle. Regular follow-up examinations are recommended to eliminate the possibility of protrusion and detachment of the J retention wire, even if the clinical course after implantation is stable for a prolonged period.
