We modified the previously described DMELD score in deceased donor liver transplant, to (D+10)MELD to account for living donors being about 10 years younger than deceased donors, and tested it on living donor liver transplantation (LDLT) recipients. 500 consecutive LDLT, between July 2010 and December 2012 were retrospectively analyzed to see the effect of (D+10)MELD on patient and graft survival. Donor age alone did not influence survival. Recipients were divided into 6 classes on based on the (D+10)MELD score: Class 1 (0-399), Class 2 (400-799), Class 3 (800-1199), class 4 (1200-1599), Class 5 (1600-1999) and Class 6 (>2000)...

Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is an extremely rare cause of hyponatremia post-liver transplantation. A 15-year-old Japanese girl with recurrent cholangitis after Kasai surgery for biliary atresia underwent successful living donor liver transplantation. Peritonitis due to gastrointestinal perforation occurred. Hyponatremia gradually developed but improved after hypertonic sodium treatment. One month later, severe hyponatremia rapidly recurred. We considered the hyponatremia's cause as SIADH...

BACKGROUND: Transversus abdominis plane (TAP) block is a peripheral nerve block that reduces postoperative pain, nausea, vomiting and the need for postoperative opioids following various types of abdominal surgery. The primary aim of the present study was to evaluate the effects of TAP block on postoperative analgesia and opioid consumption in living liver donors in whom a right "J" abdominal incision was used. METHODS: This prospective, double-blinded, randomized controlled study was conducted with 50 living liver donors, aged 18-65years, who were scheduled to undergo right hepatectomy...

Since the pioneering work by Reutter and co-workers that demonstrated structural flexibility in the carbohydrate biosynthesis and glycosylation pathways, many different labs have used unnatural monosaccharide analogs to perform glycan engineering on the surface of living cells. A subset of these unnatural monosaccharides contain bioorthogonal groups that enable the selective installation of visualization or enrichment tags. These metabolic chemical reporters (MCRs) have proven to be powerful for the unbiased identification of glycoproteins; however they do have certain limitations...

In renal transplant, multiple renal arteries in a donor require meticulous vascular reconstruction for successful allograft function in the recipient. Presence of more than 4 renal arteries is usually considered to be a relative contraindication for proceeding with renal donation. We report a living-donor renal transplant procedure where preoperative radiologic imaging of the donor showed 3 left renal arteries. Two additional arteries were identified intraoperatively. All 5 arteries were reconstructed during the back-table procedure, and the allograft was implanted in the recipient...

Refinement of immunosuppressive strategies has led to further improvement of kidney graft survival in recent years. Currently, the main limitations to long-term graft survival are life-threatening side effects of immunosuppression and chronic allograft injury, emphasizing the need for innovative immunosuppressive regimens that resolve this therapeutic dilemma. Several cell therapeutic approaches to immunosuppression and donor-specific unresponsiveness have been tested in early phase I and phase II clinical trials in kidney transplantation...

INTRODUCTION: Kidney transplantation (KT) is the preferred treatment for patients with end-stage renal disease (ESRD). To reduce the morbidity of the open surgery, a robotic-assisted approach has been recently introduced. Our aim is to evaluate surgical and functional results on 17 cases of robotic-assisted kidney transplantation (RAKT) performed at the same institution. MATERIALS AND METHODS: From July 2015 to June 2016, we performed 17 cases of RAKT from living donors in pre-emptive patients, who underwent laparoscopic nephrectomy...

The arabino-configured analog of uridine with a propargyl group at the 2'-position was synthesized and incorporated into DNA by solid-phase chemistry. The fluorescence quantum yields of DNA strands that were postsynthetically modified by blue and green emitting cyanine-styryl dyes were improved due to the arabino-configured anchor. These oligonucleotides were used as energy transfer donors in hybrids with oligonucleotides modified with acceptor dyes that emit in the yellow-red range. These combinations give energy transfer pairs with blue-yellow, blue-red and green-red emission color changes...

We previously reported results of interferon (IFN)-free daclatasvir and asunaprevir for the treatment of recurrent hepatitis C virus (HCV) genotype 1 infection after liver transplantation (LT). Here we report three patients who achieved viral response with no effect on the blood concentrations of immunosuppressive agents following sofosbuvir plus ledipasvir treatment. The first patient was a 68-year-old female with HCV-related liver cirrhosis who failed to respond to pegylated-IFN and ribavirin (PEG-IFN/RBV) after living donor LT...

Methyl viologen hexafluorophosphate (MV(2+)·2PF6(-)) and dodecamethylbambus[6]uril (BU6) form crystals in which the layers of viologen dications alternate with those of a 1:2 supramolecular complex of BU6 and PF6(-). This arrangement allows for a one-electron reduction of MV(2+) ions upon UV irradiation to form MV(+•) radical cations within the crystal structure with half-lives of several hours in air. The mechanism of this photoinduced electron transfer in the solid state and the origin of the long-lived charge-separated state were studied by steady-state and transient spectroscopies, cyclic voltammetry, and electron paramagnetic resonance spectroscopy...

This article describes the design and synthesis of donor-bridge-acceptor-based semiconducting polymer dots (Pdots) that exhibit narrow-band emissions, ultrahigh brightness, and large Stokes shifts in the near-infrared (NIR) region. We systematically investigated the effect of π-bridges on the fluorescence quantum yields of the donor-bridge-acceptor-based Pdots. The Pdots could be excited by a 488 or 532 nm laser and have a high fluorescence quantum yield of 33% with a Stokes shift of more than 200 nm. The emission full width at half-maximum of the Pdots can be as narrow as 29 nm, about 2...

BACKGROUND: The association of HLA mismatching with kidney allograft survival has been well established. We examined whether amino acid mismatches at the antigen recognition site of HLA molecules represent independent and incremental risk factors for kidney graft failure (GF) beyond those mismatches assessed at the antigenic (2-digit) specificity. METHODS: Data on 240,024 kidney transplants performed between 1987 and 2009 were obtained from the Scientific Registry of Transplant Recipients...

BACKGROUND: Living donor liver transplantation is now an established technique for treating children with end-stage liver disease. Few data exist about liver transplantation for exclusively young infants, especially infants of <3 months of age. We report our single-center experience with 12 cases in which living donor liver transplantation (LT) was performed during the first 3 months of life and compare the results with those of older infants who underwent LT. All of the patients were treated at the National Center of Child Health and Development, Tokyo, Japan...

The risk of infection with avian influenza viruses for poultry workers is relatively unknown in China, and study results are often biased by the notification of only the severe human cases. Protein microarray was used to detect binding antibodies to 13 different haemagglutinin (HA1-part) antigens of avian influenza A(H5N1), A(H7N7), A(H7N9) and A(H9N2) viruses, in serum samples from poultry workers and healthy blood donors collected in the course of 3 years in Guangdong Province, China. Significantly higher antibody titre levels were detected in poultry workers when compared to blood donors for the most recent H5 and H9 strains tested...

BACKGROUND Acute liver failure (ALF) is known to be a rapidly progressive and fatal disease. Various models which could help to estimate the post-transplant outcome for ALF have been developed; however, none of them have been proved to be the definitive predictive model of accuracy. We suggest a new predictive model, and investigated which model has the highest predictive accuracy for the short-term outcome in patients who underwent living donor liver transplantation (LDLT) due to ALF. MATERIAL AND METHODS Data from a total 88 patients were collected retrospectively...

We analyzed the effectiveness of paravertebral-block for immediate postoperative pain control in living liver donors. Specifically, we sought to determine whether or not the addition of paravertebral catheters with continuous ropivacaine infusion would decrease postoperative opioid use and reduce the incidence of adverse effects and complications. We reviewed the records of 26 patients who underwent right-lobe living donor hepatectomy (RLDH): 16 with and 10 without such catheters. The primary outcome was opioid use on postoperative day (POD) 1 through 3...

BACKGROUND: The objective of the study was to establish a right-lobe graft weight (GW) estimation formula for living donor liver transplantation (LDLT) from right-lobe graft volume without veins (GVw/o_veins), including portal vein and hepatic vein measured by computed tomographic (CT) volumetry, and to compare its estimation accuracy with those of existing formulas. Right-lobe GW estimation formulas established with the use of graft volume with veins (GVw_veins) sacrifice accuracy because GW measured intra-operatively excludes the weight of blood in the veins...
