Feasibility of long-range telesurgical robotic radical gastrectomy in a live porcine model.

Background: Telesurgery has been made increasingly possible with the advancements in robotic surgical platforms and network connectivity. However, long-distance transnational complex robotic surgeries such as gastrectomy have yet to be attempted.

Methods: Multiple transnational network connections by Science Innovation Network (SINET), Japan Gigabit Network (JGN), and Arterial Research and Education Network in Asia-Pacific (ARENA-PAC) were established and tested by multiple surgeons in a dry box model.

Genotoxicity evaluation of fucoidan-rich sporophyll.

Unlabelled: The aim of this study was to investigate genotoxicity of fucoidan-rich sporophyll (FUPS) using a three-component test battery. Our sulfate analysis method showed that FUPS extract contained 14% fucoidan sulfate. The reverse mutation assay showed that the FUPS extract did not increase the number of revertant colonies in any of the five bacterial strains tested, regardless of metabolic activation by S9 mix.

Evaluation of acute, repeated dose 28-day and 13-week oral toxicity and genotoxicity of a standardized fraction (HemoHIM) from .

HemoHIM is a functional food ingredient comprising a triple herbal combination of extracts from Nakai, Makino, and Pallas. It was developed to aid the recovery of impaired immune function. Although it is widely used to treat various immune disorders in Korea, its potential toxicity has not been extensively investigated.

Compound K promotes thermogenic signature and mitochondrial biogenesis via the UCP1-SIRT3-PGC1α signaling pathway.

Compound K (CK), an active ingredient in ginseng, has anti-cancer, anti-inflammatory, and antioxidant properties. However, its effects on thermogenesis and mitochondrial dynamics in white adipose tissue (WAT) adipocytes are not well understood. This study explores CK's impact on thermogenesis and mitochondrial metabolism in cold-exposed mice and mouse stromal vascular fraction (SVF) cells.

A three-dimensional mouse liver organoid platform for assessing EDCs metabolites simulating liver metabolism.

Hepatic metabolism is an important process for evaluate the potential activity and toxicity of endocrine disrupting chemicals (EDCs) metabolites. Organization for Economic Co-operation and Development (OECD) has advocated the development of in vitro assays that mimic in vivo hepatic metabolism to eventually replace classical animal tests. In response to this need, we established a 3D mouse liver organoid (mLO) platform that mimics the animal model and is distinct from existing models.
