Laparoscopically assisted aneurysmorrhaphy for iliac artery aneurysms following endovascular repair: reports of two cases.

Endovascular aneurysm repair (EVAR) is commonly utilized for iliac artery aneurysms (IAA), yet some cases necessitate additional intervention due to aneurysm re-expansion. We report two cases: a 68-year-old male with a left internal IAA (IIAA) and an 80-year-old female with both a left common iliac artery aneurysm (CIAA) and IIAA, who underwent aneurysmorrhaphy following initial EVAR. Both procedures were successful, significantly reducing aneurysm size without immediate complications.

Tetraplegia After Aortic Arch Surgery in Patients With Cervical Spinal Stenosis.

We report 2 rare cases of tetraplegia after total aortic arch replacement with frozen elephant trunk that were attributable to cervical spinal stenosis. Cervical spinal stenosis can increase the vulnerability of the spinal cord to ischemia and may increase the risk of spinal cord injury in operation with circulatory arrest.

Ecological, physiological, and biomechanical differences between gametophytes and sporophytes of Chondrus ocellatus (Gigartinales, Rhodophyta).

Although variation among habitats in the ratio of gametophytes to sporophytes has been reported in various gigartinacean species, factors controlling the phase ratio remain poorly understood. Over 18 months, we examined the phase ratio of Chondrus ocellatus at three sites: a sheltered intertidal site, Hiruga A; an exposed intertidal site, Hiruga B; and a subtidal site, Shikimi. The mean proportion of gametophytes at Hiruga A (73.

Causes of anxiety among teachers giving face-to-face lessons after the reopening of schools during the COVID-19 pandemic: a cross-sectional study.

Background: Coronavirus infections are spreading rapidly worldwide, and primary and middle schools are closed in many countries. After the state of emergency was lifted in Japan, schools have reopened, and teachers are conducting face-to-face classes while maintaining safety precautions. This study aimed to assess the factors contributing to infection-related anxiety and educational anxiety among teachers conducting face-to-face classes during the COVID-19 pandemic after schools reopened.

A Case of Thoracic Endovascular Aortic Repair Using Carotid Access with Axillary-Carotid Bypass for Descending Aortic Aneurysm in a Patient with Aortoiliac Occlusive Disease.

The authors report a 71-year-old male with descending thoracic aortic aneurysm and multiple risk factors (aortoiliac occlusive disease, obesity, ascending aorta dilatation, and history of left ventriculoperitoneal shunt for hydrocephalus) who was treated with thoracic endovascular aortic repair (TEVAR) via left common carotid artery (LCCA) access and left axillary-carotid artery (Ax-CA) bypass; this approach shortened the LCCA clamp time during the procedure. The patient was discharged without any complications. TEVAR via LCCA access with left Ax-CA bypass is a useful and safe procedure for patients in whom conventional femoral artery access is not feasible.

Is ganglionated plexus ablation effective for treating atrial fibrillation?

Purpose: Very few studies have investigated the efficacy of ganglionated plexus ablation during the conventional maze procedure. In this study, we sought to evaluate its additive effect in reducing recurrent atrial fibrillation after concomitant maze surgery.

Methods: A retrospective study was conducted of 79 patients who underwent Cox maze IV concomitantly with open-heart surgery with (GP group) or without (Maze group) ganglionated plexus mapping.

A prospective, randomized study of inhaled prostacyclin versus nitric oxide in patients with residual pulmonary hypertension after pulmonary endarterectomy.

Objectives: Pulmonary endarterectomy (PEA) is an effective treatment for chronic thromboembolic pulmonary hypertension (CTEPH), but postoperative residual hypertension leads to in-hospital mortality. Inhaled epoprostenol sodium (PGI) and NO are administered for pulmonary hypertension after cardiothoracic surgery. This prospective study provides the first comparative evaluation of the effects of inhaled PGI and NO on pulmonary hemodynamics, systemic hemodynamics, and gas exchange in patients developing residual pulmonary hypertension after PEA.

Endovascular Treatment for Proximal Anastomotic Pseudoaneurysm after Total Arch Replacement in Behcet's Disease.

A 17-year-old patient underwent total arch replacement for aortic arch aneurysm due to vascular Behcet's disease (BD). Follow-up computed tomography, performed 6 months after the operation, demonstrated pseudoaneurysm formation at the proximal anastomotic site. We performed endovascular treatment and used a short stent graft that was originally designed for abdominal aortic aneurysm.

A phase 1 clinical trial of the selective BTK inhibitor ONO/GS-4059 in relapsed and refractory mature B-cell malignancies.

We report the results of a multicenter phase 1 dose-escalation study of the selective Bruton tyrosine kinase (BTK) inhibitor ONO/GS-4059 in 90 patients with relapsed/refractory B-cell malignancies. There were 9 dose-escalation cohorts ranging from 20 mg to 600 mg once daily with twice-daily regimens of 240 mg and 300 mg. Twenty-four of 25 evaluable chronic lymphocytic leukemia (CLL) patients (96%) responded to ONO/GS-4059, with a median treatment duration of 80 weeks; 21 CLL patients remain on treatment.

Exposure of a herbivorous fish to ¹³⁴Cs and ¹³⁷Cs from the riverbed following the Fukushima disaster.

Ayu Plecoglossus altivelis, a herbivorous fish, is an important fishery resource and key component of the foodweb in many Japanese streams. Radionuclide contamination of this species is likely transferred to higher trophic levels, include humans, in the food chain. After the Fukushima accident in March 2011, ayu were exposed to highly contaminated silt while feeding on algae attached to the riverbed stones.

[Toward a paradigm for universal procedures of valve repair].

We developed novel methods to simplify valve repair techniques.Adequate exposure is crucial for mitral valve surgery. The right side of the pericardium is sutured to the chest wall, and both cava are mobilized and hitched up to the left.

[A case of mediastinal lymph node metastasis from rectal cancer successfully treated by carbon ion radiotherapy].

We report a case of mediastinal lymph node metastasis from rectal cancer successfully treated by carbon ion radiotherapy. A 65-year-old woman underwent sigmoid colostomy against unresectable rectal cancer. After chemoradiotherapy, primary rectal cancer became resectable and low anterior resection was performed.

Effects of tributyltin on the energy metabolism of pen shell (Atrina pectinata japonica).

We examined the effects of tributyltin (TBT) on aerobic and anaerobic energy metabolism of pen shell (Atrina pectinata japonica). We exposed pen shells to TBT at nominal concentrations of 0 (control) and 1.0microg/l for 72h under aerobic condition.

Tributyltin contamination of bivalves in coastal areas around northern Kyushu, Japan.

We determined tributyltin (TBT) concentrations in bivalve samples of blue mussel (Myitlus edulis), Manila clam (Ruditapes philippinarum) and pen shell (Atrina pectinata) collected from coastal areas around northern Kyushu in 1998 and 2001. TBT was detected in all bivalve samples collected, ranging in concentration from 0.008 to 0.

Liquid chromatography and differential scanning calorimetry studies on the states of water in polystyrene-divinylbenzene copolymer gels.

The thermal phase transition behavior of water incorporated in crosslinked polystyrene-divinylbenzene copolymer (PS-DVB) gel packings for liquid chromatography was investigated by differential scanning calorimetry. Free or bulk water, freezable bound or intermediate water, and nonfreezing water were observed for TSKgel Styrene-250 samples, while only free water and nonfreezing water were observed for TSKgel Styrene-60 samples. Freezable bound water and nonfreezing water in these gel samples were considered to be water confined in pores of the polymer gels.
