Living donor right hepatectomy (LDRH) is currently the most common donor surgery in adult-to-adult living donor liver transplantation although the morbidity and mortality reported in living donors still contradicts the Hippocratic tenet of “do no harm”. Achieving low complication rates in LDRH remains a matter of major concern. Living donor surgery is performed worldwide as an established solution to the donor shortage. The aim of this study was to assess the current status of LDRH and comment on the future of the procedure; assessment was made from the standpoint of optimizing the donor selection criteria and reducing morbidity based on both the authors’ 8-year institutional experience and a literature review. New possibilities have been explored regarding selection criteria. The safety of living donors with unfavorable conditions, such as low remnant liver volume, fatty change, or old age, should also be considered. Abdominal incisions have become shorter, even without laparoscopic assistance; upper midline laparotomy is the primary incision used in more than 400 consecutive LDRHs in the authors’ institution. Various surgical techniques based on preoperative imaging technology of vascular and biliary anomalies have decreased the anatomical barriers in LDRH. Operative time has been reduced, with low blood loss. Laparoscopic or robotic LDRH has been tried in only a few selected donors. The LDRH-specific, long-term outcomes remain to be addressed. The follow-up duration of these studies should be long enough to address possible late complications. Donor safety, which is the highest priority, is ensured by three factors: preoperative selection, intraoperative surgical technique, and postoperative management. These three focus areas should be continuously refined, with the ultimate goal of zero morbidity.

Wilson disease (WD) is an autosomal recessive disorder of copper transport caused by alteration of the adenosine triphosphatase 7B gene. It is rare to diagnose WD below the age of three years. Molecular genetic testing is one of the most important diagnostic methods and may confirm the diagnosis in equivocal cases. We report a case of a 9-mo old boy with WD who presented as chronic hepatitis. Genetic analysis showed compound heterozygotes of p.G1186S and c.4006delA.

Herein,we report a highly active K-added Ru/MgO catalyst for hydrogen storage into aromatic benzyltoluenes at low temperatures to advance liquid organic hydrogen carrier *** hydrogenation activity of Ru/K/MgO catalysts exhibits a volcano-shaped dependence on the K content at the maximum with 0.02 wt%.This is in good agreement with the strength and capacity of H_(2) adsorption derived from basicity,despite a gradual decrease in the textural property and the corresponding increase in the Ru particle size with increasing the K *** functional theory calculations show that heterolytic hydrogen adsorption properties(strength and polarization)are facilitated up to a specific density of K on the Ru–MgO interface and excessive K suppresses heterolytic H_(2) adsorption by direct interaction between K and hydrogen,assuring the hydrogenation activity and H_(2) adsorption capability of Ru/K/MgO ***,the Ru/K/MgO catalyst,when K is added in an optimal amount,is highly effective to accelerate hydrogen storage kinetics at low temperatures owing to the enhanced heterolytic H_(2) adsorption.
