Covering Trick and Embolic Volume [PDF]
arXiv, 2019 Embolic volume of compact manifolds is defined in terms of Berger's embolic inequality. In this paper, we show a result of relating embolic volume to the first Betti number. The proof relies on Gromov's covering argument appeared in systolic geometry. Berger called this method covering trick. We exploit and present more details to covering trick in the

Embolic volume and Betti numbers [PDF]
arXiv, 2019 We show a new result of relating embolic volume of compact manifolds to Betti numbers. The result is an improvement to Durumeric's previous work. The proof is based on Gromov's method appeared in systolic geometry.

Hemobilia due to cystic artery pseudoaneurysm: A rare late complication of laparoscopic cholecystectomy [PDF]
, 2017 We discuss a patient with late presentation of hemobilia following cholecystectomy, which is unusual because pseudoaneurysm caused by vascular injury during surgery typically presents soon after surgery.

Comparison of conservative treatment versus transcatheter arterial embolisation for the treatment of spontaneously ruptured hepatocellular carcinoma [PDF]
, 2018 Purpose: To elucidate the prognostic factors in the spontaneous rupture of hepatocellular carcinoma (HCC) and to determine whether transcatheter arterial embolisation (TAE) is associated with better prognosis compared to conservative treatment.

Classical and Late‐Onset SOS/VOD After Allogeneic HSCT: A Japanese Transplant Registry Analysis
American Journal of Hematology, EarlyView.ABSTRACT Sinusoidal obstruction syndrome/veno‐occlusive disease (SOS/VOD) is a lethal complication of allogeneic hematopoietic stem cell transplantation (allo‐HSCT). According to the 2016 European Society for Blood and Marrow Transplantation criteria, SOS/VOD is classified into classical SOS/VOD and late‐onset SOS/VOD, but their similarities and ...
