Introduction: The electrothermal bipolar vessel-sealing device (BVSD) is known to supply a strong vessel-sealing power. However, only few studies have reported lymph node dissection (LND) using only BVSD during laparoscopic surgery for gastric cancer. The purpose of this study was to investigate the feasibility of LND using BVSD during reduced port laparoscopic distal gastrectomy for gastric cancer.
Methods: From May 2015, patients in whom three- or single-port laparoscopic distal gastrectomy had been engaged for gastric cancer were enrolled in this study. We performed D1+ or D2 LND using only LigaSure Maryland (Medtronics, Minneapolis, MN), a recently developed BVSD. Clinical outcomes of these patients were investigated.
Results: From May 2015 to November 2016, 20 patients were enrolled in this study. The mean operation time was 262.6 ± 36.6 (200-340) minutes. The mean time for LND was 124.7 ± 19.2 (93-171) minutes. Only one patient had a morbidity of Clavien-Dindo grade more than II. No mortality was observed in all patients. The mean number of retrieved lymph nodes was 46.8 ± 22.8 (15-105).
Conclusions: LND using the Maryland jaw type BVSD was feasible during reduced port (single- or three-port) laparoscopic distal gastrectomy for gastric cancer. Objectively evaluating the potential advantages of BVSD in reduced port laparoscopic surgery is necessary.

<b>Background and Objective:</b> Cadmium (Cd) is one of the heavy metal pollutants and its accumulation impacts the sustainability of marine organisms. Current research aimed to isolate and identify the cadmium-reducing bacteria from contaminated coastal sediment in Karangsong Port, Indramayu, Indonesia. The isolates were investigated for their potential to reduce cadmium and showed the cadmium reduction drastically up to 50% at 6 hrs treated under different cadmium concentrations of 0, 5, 1 and 1.

The introduction and spread of invasive insects is accelerating worldwide owing to human activities, such as trade and transportation development; in particular, ports are hubs and routes for invasive insects, including ants. We surveyed ant populations in eight ports from 2021 to 2023 using pitfall traps. A total of 316,975 ants belonging to four subfamilies, 26 genera and 44 species were identified as , , and .

Addressing quadriceps dysfunction is crucial to improve function, reduce the reinjury risk, and maintain long-term knee health. While deficits specific to the quadriceps are well documented, less is known about the effect of an ACL injury on other lower extremity muscle groups.

Cognitive dysfunction is frequently reported in individuals with postural orthostatic tachycardia syndrome (POTS), possibly resulting from reduced cerebral blood flow (CBF). We used brain SPECT, an accessible imaging modality that has not been systematically evaluated in this patient group. Retrospective review of participants from our registry was undertaken to identify those who had a brain SPECT performed for investigation of cognitive dysfunction.

The fermentative production of valuable chemicals from lignocellulosic feedstocks has attracted considerable attention. Although Saccharomyces cerevisiae is a promising microbial host, it lacks the ability to efficiently metabolize xylose, a major component of lignocellulosic feedstocks. The xylose oxidative pathway offers advantages such as simplified metabolic regulation and fewer enzymatic steps.
