The management of locally advanced esophageal cancer typically involves esophagectomy; however, postoperative complications, particularly anastomotic stricture, remain prevalent. Anastomotic stricture can severely compromise patients' quality of life by leading to difficulties in food intake. Although endoscopic balloon dilation has become a standard treatment for gastrointestinal strictures, its efficacy is often limited due to the risk of perforation and the potential for recurrent stricture, necessitating multiple interventions.

Japan is experiencing a dramatic spike in streptococcal toxic shock syndrome (STSS) cases, exceeding the previous year's statistics. This life-threatening illness, caused by , has been connected not only to the relaxation of COVID-19 precautions but also to the prolonged effects of confinement and lack of contact with the surrounding environment/ecology. The condition is characterized by a sudden onset of symptoms, including high fever, rash, and shock, and demands immediate medical intervention.

Introduction: Repairing damaged cartilage poses significant challenges, particularly in cases of congenital cartilage defects such as microtia or congenital tracheal stenosis, or as a consequence of traumatic injury, as the regenerative potential of cartilage is inherently limited. Stem cell therapy and tissue engineering offer promising approaches to overcome these limitations in cartilage healing. However, the challenge lies in the size of cartilage-containing organs, which necessitates a large quantity of cells to fill the damaged areas.

STRAIGHTMORPH: A Voice Morphing Tool for Research in Voice Communication Sciences.

Open Res Eur

January 2025

Center for Innovative Research and Liaison, Wakayama University, Wakayama, Wakayama Prefecture, Japan.

The purpose of this paper is to make easily available to the scientific community an efficient voice morphing tool called STRAIGHTMORPH and provide a short tutorial on its use with examples. STRAIGHTMORPH consists of a set of Matlab functions allowing the generation of high-quality, parametrically-controlled morphs of an arbitrary number of voice samples. A first step consists in extracting an 'mObject' for each voice sample, with accurate tracking of the fundamental frequency contour and manual definition of Time and Frequency anchors corresponding across samples to be morphed.

Objectives: Trunk control involves multiple brain regions related to motor control systems. Therefore, patients with central nervous system (CNS) disorders frequently exhibit impaired trunk control, decreasing their activities of daily living (ADL). Although some therapeutic interventions for trunk impairments have been effective, their general effects on CNS disorders remain unclear.

Saturn's rings have been estimated to be as young as about 100 to 400 million years old according to the hypothesis that non-icy micrometeoroid bombardment acts to darken the rings over time and the Cassini observation indicated that the ring particles appear to be relatively clean. These young age estimates assume that the rings formed out of pure water ice particles with a high accretion efficiency of impacting non-icy micrometeoroid material ( ≳ 10%). Here we show, using numerical simulations of hypervelocity micrometeoroid impacts on a ring particle, that non-icy material may not be as readily accreted as previously thought.

We present a case of a 60-year-old man with claudication in his right foot; the patient had received stent-graft implantation for the right superficial femoral artery (SFA) 1 year ago. Computed tomography angiography suggested stent occlusion of the right SFA, and a thrombus was considered to cause occlusion. To avoid distal embolization, we performed lesion recanalization via a trans-ankle intervention.

Background: Late-stage human immunodeficiency virus (HIV) infection is typically characterized by low CD4 + T-cell count. We previously showed that profound changes in the monocyte turnover (MTO) rate in rhesus macaques infected by the simian immunodeficiency virus (SIV) outperforms declining CD4 + T-cell counts in predicting rapid health decline associated with progression to terminal disease. High MTO is associated with increased tissue macrophage death.

Proximal gastrectomy (PG) has reemerged as a viable surgical option for managing proximal gastric cancer and gastroesophageal junction cancer, particularly for early-stage tumors, offering potential advantages over total gastrectomy (TG). This review examines the evolution of PG, emphasizing surgical techniques and outcomes. Although PG was initially abandoned due to postoperative complications such as reflux esophagitis, advances in reconstruction methods, such as the double-flap technique and double-tract reconstruction, have significantly improved patient quality of life and reduced complications.

Angiosarcoma (AS) is a rare, aggressive malignancy originating from vascular or lymphatic endothelial cells. Despite its severity, little is known about its epidemiology, and no geographical regions have previously been identified as having an exceptionally high incidence. We retrospectively analyzed medical records spanning 37 years (1987-2023) in Okinawa, Japan, identifying 135 cases of AS that were used to calculate its incidence.
