Short and Mid-term Outcome of Radiofrequency Ablation without Concomitant Phlebectomy/Sclerotherapy for Tributary Varicose Veins.

Endovenous surgery in the treatment of varicose veins generally consists of laser or radiofrequency ablation (RFA) as endovenous thermal ablation (ETA) with a phlebectomy or foam sclerotherapy of tributary varicose veins to improve symptomatic or cosmetic problems. Nevertheless, the efficacy of their concomitant treatments is still controversial for a decade. In the guidelines of the Japanese Society of Phlebology, concomitant phlebectomy of tributary varicose veins with ETA is described that it is not recommended officially.

The Pharmaceutical Composition of Rocuronium Bromide May Promote Catecholamine Release From PC-12 Cells.

Background: Several cases of pheochromocytoma presenting with hypertensive crises after anesthesia induction, possibly caused by rocuronium injection, have been reported. Rocuronium has two compositions: rocuronium bromide (RB) in sodium acetate hydrate/acetic acid buffer solution (acetic acid vehicle) and RB in glycine/hydrochloric acid buffer solution (hydrochloric acid vehicle). This study assessed the effect of rocuronium composition on the release of catecholamine from PC-12 rat adrenal pheochromocytoma cells.

Outcome-based simulation training for ultrasound-guided central venous catheter placement: clinical impact on preventing mechanical complications.

Background: Central venous catheter placement has been associated with mechanical complications, some of which can be life-threatening. Recent studies have shown that simulation-based education on ultrasound-guided central venous catheter placement improves puncture success rates; however, its effect on reducing mechanical complications remains unclear. This observational study examined how outcome-based simulation training for ultrasound-guided central venous catheter placement affects the incidence of mechanical complications in a clinical setting.

Biochemical evidence for the diversity of LHCI proteins in PSI-LHCI from the red alga Galdieria sulphuraria NIES-3638.

Red algae are photosynthetic eukaryotes whose light-harvesting complexes (LHCs) associate with photosystem I (PSI). In this study, we examined characteristics of PSI-LHCI, PSI, and LHCI isolated from the red alga Galdieria sulphuraria NIES-3638. The PSI-LHCI supercomplexes were purified using anion-exchange chromatography followed by hydrophobic-interaction chromatography, and finally by trehalose density gradient centrifugation.

Exploring condition in which people accept AI over human judgements on justified defection.

As artificial intelligence (AI) technology is introduced into different areas of society, understanding people's willingness to accept AI decisions emerges as a critical scientific and societal issue. It is an open question whether people can accept the judgement of humans or AI in situations where they are unsure of their judgement, as in the trolley problem. Here, we focus on justified defection (non-cooperation with a bad person) in indirect reciprocity because it has been shown that people avoid judging justified defection as good or bad.
