Routing in wireless sensor networks (WSNs) is very challenging due to their inherent characteristics of large scale, no global identification, dynamic topology, and very limited power, memory, and computational capacities for each sensor. Recent research on WSNs routing protocol has proved that data-centric technologies are needed for performing in-network(More)
BACKGROUND Human leukocyte antigen (HLA) antibodies, especially those that fix complement, are associated with antibody-mediated rejection and graft failure. The C1q assay on single antigen beads detects a subset of HLA antibodies that can fix complement and precede C4d deposition. The aim of this study was to determine whether C1q-fixing antibodies(More)
It has been known for 40 years that cytotoxic human leukocyte antigen (HLA) antibodies are associated with graft rejection. However, the complement-dependent cytotoxicity assay (CDC) used to define these clinically deleterious antibodies suffers from a lack of sensitivity and specificity. Recently, methods exploiting immunoglobulin G (IgG) antibody binding(More)
BACKGROUND The indications for laparoscopic spleen-preserving distal pancreatectomy (LSPDP) and its morbidity compared with laparoscopic distal pancreatectomy with splenectomy (LDPS) are ill-defined. This study aimed to share the indications for spleen-preservation and investigate the safety and outcome of LSPDP at our institution. METHODS A retrospective(More)
Trametes Villosa Laccase (TVL) was immobilized through physical adsorption on SBA-15 mesoporous silica and the immobilized TVL was used in the oxidative coupling of trans-resveratrol. Higher loading and activity of the immobilized enzyme on SBA-15 were obtained when compared with the free enzyme. The effects of reaction conditions, such as buffer type, pH,(More)
(R)-1-Chloro-3-(1-naphthyloxy)-2-propanol, which is the key intermediate of (S)-propranolol, was successfully prepared via enantioselective transesterification catalyzed by lipase under ultrasound irradiation. Compared with conventional shaking, the enzyme activity and enantioselectivity were dramatically increased under ultrasound exposure. Effects of(More)
To analyze the incidence of instrument separation (IS) and the factors influencing it, when associated with Mtwo rotary system (VDW, Munich, Germany) during endodontic therapy. A retrospective study involving a total of 24,108 root canals (11,036 endodontic treated teeth) was conducted at Nanjing Stomatology Hospital between January 2011 and March 2013. The(More)
Long-term outcomes following renal transplantation remain disappointing. Recently, interest has focused on the antibody-mediated component of allograft injury and the deleterious effects of DSA. We applied a novel C1q solid-phase assay in parallel with the standard IgG SAB assay to identify DSA with the potential to activate complement by binding C1q. Among(More)
BACKGROUND Intravenous gammaglobulin (i.v.IG) contains anti-idiotypic antibodies that are potent inhibitors of HLA-specific alloantibodies in vitro and in vivo. In addition, highly HLA-allosensitized patients awaiting transplantation can have HLA alloantibody levels reduced dramatically by i.v.IG infusions, and subsequent transplantation can be accomplished(More)
BACKGROUND Donor-specific antibodies (DSA) against human leukocyte antigens complicate transplantation with the potential for acute antibody-mediated rejection (AMR). Complement-fixing antibodies are required to initiate the complement cascade. Not all DSAs, however, can fix complement. METHODS A novel C1q assay was developed to detect the sub-set of(More)
